ABSTRACT Twitter has become a popular microblogging service that allows millions of active users share news, emergent social events, personal opinions, etc. That leads to a large amount of data producing every day and the problem of managing tweets becomes extremely difficult. To categorize the tweets and make easily in searching, the users can use the hashtags embedding in their tweets. However, valid hashtags are not restricted which lead to a very heterogeneous set of hashtags created on Twitter, increasing the difficulty of tweet categorization. In this paper, we propose a hashtag recommendation method based on analyzing the content of tweets, user characteristics, and currently popular hashtags on Twitter. The proposed method uses personal profiles of the users to discover the relevant hashtags. First, a combination of tweet contents and user characteristics is used to find the top-k similar tweets. We exploit the content of historical tweets, used hashtags, and the social interaction to build the user profiles. The user characteristics can help to find the close users and enhance the accuracy of finding the similar tweets to extract the hashtag candidates. Then a set of hashtag candidates is ranked based on their popularity in long and short periods. The experiments on tweet data showed that the proposed method significantly improves the performance of hashtag recommendation systems.


Introduction. Social instability increases the importance of tolerance of uncertainty among representatives of different social and professional groups. In the context of the COVID-19 pandemic, educators' tolerance of uncertainty as a probable determinant of their psychological health is of particular interest for researchers. Aim: to study tolerance of uncertainty as a determinant of educational staff's psychological health in conditions of social tension. Methods: D. McLain's MSTAT-II (adapted by E.M. Osin), T. Galkina & N. Artemtseva's Attitude to Psychological Health Scale, Scale of Positive Mental Health by J. Lukat et al., and Locus of Health Control questionnaire. Results. It was found that the most pronounced components of tolerance of uncertainty were the attitude to novelty and preference of uncertainty. Uncertainty tolerance components affected most aspects of educators' psychological health. Conclusion. Tolerance of uncertainty should be seen as a determinant of educators' psychological health.

The research at hand investigates the effects of neuropsychological treatment on reading efficiency of students suffering from developmental dyslexia (L-type). Eighty two students suspected of dyslexia were elected from community of students the third, forth, and fifth grade elementary school through cluster sampling. Diagnostic tests (including Wechsler's intelligence scale for children reading disorder, ADHD, and conduct disorder tests) were administered based on which thirty students were purposefully selected .The evaluated sample was then randomly divided into two categories based on Bakker's classification, each consisting of fifteen students (the L-type experimental and control groups). Pre-tests were then administered after which the L-type experimental group received neuropsychological treatments (HSS) through 20 sessions. Control group, however, did not receive any treatment. Subsequent to the mentioned procedures, post-tests were administered (immediately) while follow up tests were administered (after a period of four months). Data was analyzed through Mixed ANOVA, variance analysis of repeated measure and Dependant T-Tests. Research findings indicate that neuropsychological interventions based on Bakker's balance model of reading, increases reading accuracy and comprehension of students suffering from developmental dyslexia of the L-type. Follow up tests indicated the permanence of the effects of neuropsychological interventions after duration of four months. It is recommended that learning disability educators, physician, and psychologists administer Bakker's neuropsychological treatment methods for the improvement of the reading efficiency in students suffering from developmental dyslexia. :


The alumina powder was treated at a high temperature (1000°C). Dense (porosity of less than 2%), solid (1280 ± 30 HV0.3) and wear-resistant coatings based on heat-treated alumina powder were obtained by a multi-chamber detonation sprayer on the steel substrate. The microstructure, microhardness and the wear resistance of the alumina coatings were investigated.


Aimed at short propagation distance and poor anti-jamming capability of narrow-band signal in underwater acoustic(UWA) communication,a new UWA communication scheme is proposed on the basis of fractional Fourier transform which used LFM signals as carrier signals.LFM signals are divided into groups as coding signals in time domain and the coding signals are decoded by using pulse position modulation(PPM) in fractional domain.A Rake receiver is presented to suppress UWA channel's multi-path effect which could lead to inter-symbol interference(ISI).Comparing to traditional UWA communication,this scheme has strong anti-interference ability and high communication rate;the maximum communication rate can be up to 800 bit/s.The feasibility and robustness of this system are verified through simulations,and it is helpful to the long range UWA communication.


Dogimont, C., Slama, S., Martin, J., Lecoq, H., and Pitrat, M. 1996. Sources of resistance to cucurbit aphid-borne yellows luteovirus in a melon germ plasm collection. Plant Dis. 80:13791382. Cucurbit aphid-borne yellows virus (CABYV) is a tentative member of the luteovirus group transmitted by Myzus persicae and Aphis gossypii. Five hundred twenty-three Cucumis melo L. accessions were screened in field conditions in the south of France under severe natural inoculum pressure. Double antibody sandwich-enzyme-linked immunosorbent assays were conducted to confirm the presence or absence of virus in the plants. Several potential sources of CABYV resistance were found, most originating from India, but some from Korea and Africa. The resistance of the most promising genotypes was confirmed in a field trial in five locations and under controlled conditions, with viruliferous Myzus persicae used to inoculate plants. Genotypes found to be resistant were Faizabadi Phoont, 90625, PI 124112, PI 124440, PI 255478, PI 282448, and PI 414723.


Frequency is a vital factor for power system operation and protection. This paper is on extraction of frequency feature for fault/event analysis based on wavelet transform (WT) and fractal geometry (FG). The frequency signal is decomposed by WT-based multiresolution analysis (MRA) and a family of wavelet coefficients is obtained. A maxima line is constructed by connecting the maximum point in the wavelet coefficients across all the decomposition levels. A differential box counting (DBC) method based on FG is applied to compute the fractal dimension of the maxima line. It is realized that the feature of a frequency signal can be characterized by a fraction number-fractal dimension. A simulation is carried out in PSS/E to generate different faults in the power system. The proposed algorithm is implemented to extract the features of the faults. The results verify the effectiveness of the proposed method.


Abstract : During the course of a Young Investigator Award from the Army Research Office (Materials Program) the research in the PI's group has developed into three different but related areas of scientific discovery. The first of these areas concerns the optical properties of novel transition metal nanoparticle topology which we call %"Dendnmerr Metal Nanocomposites%%. This novel metal nanoparticle system was investigated under support by the ARO for novel optical limiting and enhanced metal emission properties. We found in particular that gold-metal dendrimer nanocomposites have very strong optical limiting properties that may be useful for eye and sensor protection devices in the visible and near Infrared spectral regions. The emission properties of both and silver dendrimer metal nanocomposites were also investigated by time-resolved upconversion spectroscopy. From these measurements the PI's group found that the efficiency at emission was enhanced in comparison to other related metal topologies and this enhancement is related to the encapsulated metal's morphology (aspect- ratio). Applications of this particular metal topology in to biological systems are currently under investigation in the PI's laboratory.


MicroRNAs (miRNAs) are a class of noncoding RNAs of 19~22 nucleotides that regulate gene expression at the post-transcriptional level. miRNAs have been demonstrated to be involved in almost all basic signaling pathways. Recent increased data indicate that miRNAs are closely associated with tumor genesis, differentiation, metastasis and relapse. They might be used as for early diagnosis, treatment and prognosis of this disease. miRNAs might act as new biomarkers for tumor diagnosis and new targets for tumor gene therapy. This article fo cused on the relationship between miRNAs and esophageal cancer, as well as their potential use in the diagnosis, prognosis and gene therapy for esophageal cancer.

We prove the existence of solutions for the stochastic differential equation with the measurable coefficients a and b satisfying the condition and for all , where and K are constants. The driving process Z is a symmetric stable process of index . This generalizes the result of Krylov [Controlled Diffusion Processes, Springer, New York, 1980] for the case of , that is, when Z is a Brownian motion. The proof is based on integral estimates of the Krylov type for the given equation, which are also derived in this note and are of independent interest. Moreover, unlike in Krylov [Controlled Diffusion Processes, Springer, New York, 1980], we use a different approach to derive the corresponding integral estimates.


EPM/EPDM elastomers are widely used for the insulation of high and medium voltage electric cables. Insulator mechanical properties depend on the extent of vulcanization, which is obtained by manufactures using a number of different peroxides as cross-linking agents. Vul- canization occurs in the continuous vulcanization tube, a pressurized tube filled with nitrogen at high temperatures. Then, water and/or air are used to cool the cable at ambi- ent temperature. Changes of process variables cause con- siderable changes in insulator physical properties. In the present article, a genetic algorithm with zooming and elit- ist strategy is used for the determination of optimal pro- duction lines parameters to use to maximize rubber output mechanical properties. Nitrogen temperature Ts and exposition time t are assumed as production parame- ters to optimize, whereas two different output mechanical properties (tensile strength and tear resistance) are consid- ered as objective functions. Several optimization problems are analyzed both for medium and high voltage cables. A final multiobjective optimization is presented with the cor- responding Pareto frontier, where objective functions are represented by tear resistance and tensile strength. Opti- mal production Ts and t are obtained for all the cases ana- lyzed. Numerical simulations show how different peroxi- des and insulator thicknesses sensibly influence optimal production variables. V C 2008 Wiley Periodicals, Inc. J Appl


The small angular distance (<100 mas) and the huge flux ratio (107) between an Earth-like exoplanet in the socalled habitable zone and its host star makes it very difficult to direct image such systems. Nulling interferometry consists of a very powerful technique that combines destructively the light from two or more collectors to dim the starlight and to reveal faint companions in its vicinity. We have developed a new nulling experiment based on the fiber nuller principle. This fully symmetric reflective nulling bench aims at testing broadband nulling in both H and K bands as well as characterizing photonic fibers for modal filtering. We present in this paper the design, the development as well as preliminary results of the experiment.


Abstract : This final technical report presents a novel protocol to achieve invariability of nested method invocations. This protocol tolerates Byzantine faulty clients, as is necessary when methods are invoked from other distributed objects that themselves must withstand Byzantine faults. This final report further presents a detail of this protocol, an argument about its correctness and a description of its implementation and performance in a distributed object system.


Article history: Received October 10, 2011 Received in Revised form November, 14, 2011 Accepted 8 December 2011 Available online 12 December 2011 In this paper, the problem of predicting the exchange rate time series in the foreign exchange rate market is going to be solved using a time-delayed multilayer perceptron neural network with gold price as external factor. The input for the learning phase of the artificial neural network are the exchange rate data of the last five days plus the gold price in two different currencies of the exchange rate as the external factor for helping the artificial neural network improving its forecast accuracy. The five-day delay has been chosen because of the weekly cyclic behavior of the exchange rate time series with the consideration of two holidays in a week. The result of forecasts are then compared with using the multilayer peceptron neural network without gold price external factor by two most important evaluation techniques in the literature of exchange rate prediction. For the experimental analysis phase, the data of three important exchange rates of EUR/USD, GBP/USD, and USD/JPY are used. © 2012 Growing Science Ltd. All rights reserved.


This paper studies the effect of uncertainty about stochastic diffusion model on dynamic portfolio choice of an investor who maximizes utility of terminal portfolio wealth. It applies stochastic control method to obtain the closed-form solution of optimal dynamic portfolio, and uses the Bayesian rule to estimate the model parameters to do an empirical study on two different samples of Shanghai Exchange Composite Index. Results show, model uncertainty results in positive or negative hedging demand of portfolio, which depends on investor's attitude toward risk; the effect of model uncertainty is more significant with the increasing of investment horizon, the decreasing of investor's risk-aversion degree, and the decreasing of information; return's predictability enhances the effect of model uncertainty.


The Naturalis Historia by Pliny the Elder is one of the most important works of Antiquity, which influenced later understanding of Greek art and the formation of centuries of subsequent concepts, models, and methods in art history. Scholars use this work as an aid in establishing the general developmental line of Greek art production and the attribution of artifacts to individual authors. The fact that excerpts from Pliny's Naturalis Historia, especially those that describe painting and sculpture, gained the status of a reference work in studying Greek art has resulted in the discipline reading them surprisingly unambiguously.
The greatest problem in the traditional reading of Pliny's Naturalis Historia is the fact that it is usually read by individual sections that more or less correspond to the modern division of knowledge within individual academic disciplines. Although some recent studies explicitly emphasize the necessity of reading Naturalis Historia as a whole, scholars of the art of antiquity often continue to believe that the key to understanding Pliny's attitude to the artistic creativity of his own time and previous periods is hidden in the books in which the author presumably analytically describes the development of painting and sculpture.
This kind of approach to Pliny's work cannot offer a comprehensive insight into his attitude toward the art for at least two reasons. First, because of their focus on particular parts of Naturalis Historia, researchers isolate these from the context of the entire work and in reality create "new texts." Second, reading only the parts in which Pliny describes individual types of art comprises a more or less explicit idea of Pliny as an art historian; that is, an author interested in artistic production in a completely modern sense of the term.
Only a comprehensive reading of Pliny's Naturalis Historia can lead to more suitable interpretation of the entire text and its individual parts. Analyzing the structure of individual volumes or chapters and their placement within the frame of the entire work, focusing on the use of individual words and phrases in various contexts – and, last but not least, a thorough analysis of the sources Pliny uses, with an emphasis on ideas that he borrows from these sources, and on the method he uses to incorporate them into his own narrative – enables a new understanding of Pliny as an author, as well as the goals he tried to achieve through his work.
By examining Pliny's remarks about Phidias, the author shows that in Pliny's descriptions of Greek painting and sculpture we cannot seek the Greek understanding of sculptures and paintings that surrounded the people, nor can we seek a Roman view of Greek works of art that somehow ended up in Rome. In his Naturalis Historia Pliny primarily offers the reader his own politically motivated view of the world. From Pliny's descriptions of Greek sculpture, one can find out exactly as much about Greek sculpture as from the Roman copies of Greek sculptures that flooded the Roman state: both cases deal with an interpretation of the original. Thus, in the author's opinion, the obligation of the discipline – especially art history – in reading Pliny's Naturalis Historia is not to reconstruct the more or less imaginative development of Greek painting and sculpture, but to discover the political and intellectual possibilities that the interpretation of Greek (and Roman) artistic creativity offered Roman intellectuals in the middle of the 1st century AD.


I AM VERY HONOURED to have been asked to give the Sir John Rhŷs Memorial Lecture for the year 2003, and wish to present on this occasion a study of the triad in early Irish literature. I have been interested in the collections of triads in the Celtic languages for many years, in particular the Old Irish text entitled in some manuscripts Trecheng Breth Féne, 'a triad of judgements of the Irish', normally referred to simply as The Triads of Ireland. It was edited in 1906 by the great German scholar Kuno Meyer,1 but it is very much in need of another visit in the light of advances in scholarship and the discovery of other versions of the text.2 It contains two hundred and fourteen triads, three duads, seven tetrads and one nonad. At the beginning of the text, there are also thirty-one single items relating to the monasteries of Ireland. The arrangement of ideas in groups of three is attested from most recorded literatures, both oral and written. Thus we find triads in Greek, Latin, Sanskrit, Hebrew, Russian, English, Chinese, Japanese and many other languages. However, nowhere—to my knowledge—does one get


A model of concrete deformation under the high temperature heating in a loaded state is proposed. It reflects the physical nature of deformation has a rather compact form and requires a minimum number of normalized parameters. In order to describe the curve of concrete deformation and temperature parameters change exponential relationships were assumed and calibration of their coefficients was performed.


Recent wind tunnel tests have been used to establish baseline characteristics of the effect of small particle impacts on two sapphire window plates. These two window plates have been exposed to wind tunnel flowfields of approximately Mach 10 at a simulated altitude of 50,000 feet. Test conditions indicate a free stream velocity, of approximately 4800 ft/sec. Within the wind tunnel flowfield, small particles were carried along and have appeared as impact sites on the exposed surface of each window plate. Examination of the impacted sites indicate that the particles were composed of Deirin (a hard acetal homo-polymer) or stainless steel, both of which resulted in small but measurable damage to each window plate. Characterization of the plate surface appearance and impact damage was conducted at two locations: 1) the University of Alabama in Huntsville, (UAH), Optical Measurements Laboratory (OML) and, 2) Oak Ridge National Laboratories (ORNL), Optical Component Characterization Laboratory (OCCL).


Context-Aware Recommender Systems (CARSs) suffer from the cold-start problem, i.e., the inability to provide accurate recommendations for new users, items or contextual situations. In this research, we aim at solving this problem by exploiting various hybridisation techniques, from simple heuristic-based solutions to complex adaptive solutions, in order to take advantage of the strengths of different CARS algorithms while avoiding their weaknesses in a given (cold-start) situation. Our initial research based on offline experiments using various contextually-tagged rating datasets has shown that basic CARS algorithms perform very differently in different recommendation scenarios, and that they can be effectively hybridised to achieve an overall optimal performance. Further research is now required to find the optimal method for hybridisation.


Cognitive radio network is one of the emerging areas in the field of next generation wireless network. This network is an alternative and more suitable solution to the high demands of resources for facilitating integrated & multimedia services. Instead of fixed spectrum allocation as it is done in conventional wireless networks, the cognitive radio network is based on dynamic spectrum allocation procedure. The success of this radio network depends on how efficiently these spectrums are allocated. A prioritized spectrum allocation technique based on fuzzy logic is proposed in this work. The spectrum allocation is based on four input parameters priority, path loss, node velocity and spectrum efficiency


NUT midline carcinoma (NMC) is an increasingly recognized neoplasm defined by rearrangements of the nuclear protein in testis (NUT) gene (also known as NUTM1). NMC is important to diagnose for prognostic and diagnostic reasons, but to date, only a small case series and rare case reports of the cytopathologic features of NMC have been published.


"Yesterday, law was such an easy game to play...." In periods of transition, it is common for lawyers to be asked, in light of an allegedly overriding reality, to critically revisit the table of contents or categories of their discipline. In such periods it is also normal for the scientific debate of the law to be pervaded by a deep sense of uneasiness. The physiognomy of the law is, at least to a certain extent, to drive rather than to follow the evolution of reality. Accordingly, it is a symptom of pathology if reality systematically departs from rules or categories still in force. Nonetheless, law is everything but a stable artifact. Only in the easy cases does its evolution comply with the procedures that the law itself provides for its amendment. In the other cases, namely when the reality constantly deranges the rules or the legal categories and imposes itself as dominant, it is up to the science of the law to decide either if (and how) the traditional categories have to be reinforced or if (and how) they are required to be updated, accommodating the law to the reality. An example of this uneasiness emerges from the articles hereafter published as a result of a conference held at the Faculty of Law of Trento, Italy, in June 2004. The debate started from the broadly shared assumption that the performances of the traditional domestic circuits of representative democracy are increasingly challenged when a number of actors do not perceive they are properly involved in the regulatory (legislative and administrative) decisionmaking processes and before the courts. As organizers of the conference, we labeled this reality the pluralistic deficit, and we asked each of our guests to deal with this issue from the perspective of his or her highly differentiated academic background.


A new unit-distance counting code (similar to the Gray code but having error-checking properties) that offers distinct advantages in the simplicity of the digital equipment required for encoding and decoding is described. This code has application in several special areas of information processing. It is generated by a particular generalization of the family of Gray codes, which has no error- checking features, but shares with the Gray code a simple conversion relationship to the conventional binary counting code. The new code is derived, and its error-checking and code conversion properties are proven by simple combinatorial arguments. The code has a total of K(m)= 2.2m/2code words of m digits each (m any even integer). It may be employed for correction of single errors or for the detection of double errors.


Surface property of material has a great impact on the interfacial adhesion of particle and surface.Rough surfaces were used for studying scale feature of above two indicators.It could conclude from the above study of scale feature of fractal indicators that there existed two regions when fractal indicators change with scale,which were named unstable fractal region and stable region.In the process of analysing the two-dimensional surface contour,we transfered the finding of critical point into solving the quantitative relationship of sampling length and angleα.By the quantitative relationship,angleαcould be made 0to obtain the critical sampling length.As long as the sample length is greater than the critical length,stable fractal region could be obtained,and then the stable fractal dimension could be calculated,which would not affected by the resolution of instrument.In this case the fractal dimension can reflect the inherent property of rough surface,which can be used as an accurate characterization of surface roughness.Through the analysis of cleaning mechanism of solid dirt,we find that surface roughness has a great impact on interfacial adhesion.The results show that adhesion force changes with surface roughness,Ra0.4627μm,adhesion force decreases with the increase of surface roughness;1.3461μmRa2.9755μm,adhesion force increases gradually;Ra3μm,adhesion force remains the same.Adhesion force also changes with fractal indicator,it changes the opposite trend with surface roughness.


Testicular anti-Mullerian activity was evaluated in pigs from birth to 180 days. Anti-Mullerian activity was low during the first 3 postnatal days, and rose to reach its highest level between 10 and 19 days. Thereafter, anti-MUllerian capacity steadily declined, and fell abruptly after 60 days, at a time when pubertal changes are not yet detectableby histologicalexamination and the blood-testis barrier has not yet formed. The ultrastructuralappearance of Sertolicellsfrom birth to 80 days suggestsactiveglycoprotein biosynthesis,but no correlationcould be establishedbetween the fine structure of Sertolicellsand the degree of anti-Mullerian activity. We conclude that decreased biosynthesis of anti-Mullerian hormone is an early sign of testicular maturation in the postnatal pig.


This paper examines the relationship between female work status and the number of children ever born and child mortality in Orissa. The study is mainly based on the 1993 National Family Health Survey and confined only to currently married women and women who had been married only once. Results are discussed under two sections: the first considers the relationship of womens work status to the number of children ever born and the second considers its relationship to child loss. Overall the findings indicate that performing economically productive work within the house has a positive influence on the number of children ever born to a woman. Furthermore women engaged in work outside the home have fewer children than both those who earn an income by working within the home and those who do not work for an income. However the relationship between female work status and child loss is not significant when variables such as immunization and antenatal care are controlled.


Rye-wheat mixed bread samples made with substitutions of 20, 40, 60 and 80% sourdough, and control made with the addition of naturally fermented raisin extract, were examined for quality characteristics such as pH, total titratable acidity, fermentation power of dough expansion, specific volume, baking loss, water activity, color, texture, external and internal surface appearance, and sensory qualities, in order to determine the optimal ratio of sourdough in the formulation. As the incubation time of sourdough increased, pH decreased, while total titratable acidity increased. The pH of rye-wheat mixed doughs decreased with increasing sourdough content, but total titratable acidity increased. The rye-wheat mixed breads prepared with substitutions of sourdough had higher pH and lower total titratable acidity than the control group. Fermentation power of dough expansion of rye-wheat mixed doughs increased with increasing incubation time. Specific volume was maximum on the 20% substitution sourdough. Baking loss was inferior with the 80% substitution sourdough. Water activity and lightness was minimum on the control group. The higher amounts of sourdough showed the higher tendency of lightness, redness and yellowness. In the texture characteristics, hardness, gumminess, and chewiness was minimum on the control group and tended to increase with higher substitution of sourdough. Substitution of sourdough showed decrease adhesiveness. Fracturability, cohesiveness, and resilience of all rye-wheat mixed breads were not significantly different. Springiness was maximum on the 20% substitution sourdough and minimum on the 40%. A side of loaf of rye-wheat mixed breads, except for 20%, had a poor break and shred. In sensory evaluation, as substitution amount of sourdough increased, the scores of color and consistency of crumb, uniformity of crumb pore, gumminess, and overall acceptability decreased; while the density of crumb pore, springiness of crumb, aroma of rye flour, sourness, and bitterness showed the reverse effect; the 20, 40, and 60% sourdough samples obtained fairly good scores. In conclusion, these results indicated that 20~60% of sourdough could be very useful as a substitute for baker's yeast in developing rye-wheat mixed bread.


Using a femtosecond pulsed laser, ultrafast electrical pulses were optoelectronically generated on silicon and indium phosphide by edge illumination of a coplanar transmission line. Backing up theory with experiment, we demonstrate that this pulse‐generation method is material independent, thus providing a powerful tool for broadband characterization of devices made on a wide range of semiconductor substrates. We also demonstrate that edge illumination enables the generation of 550 fs electrical pulses on indium phosphide and 800 fs pulses on silicon—the fastest pulses to date on bulk silicon.


The persistent existence of the 'gender pay gap' in organisations, and the lack of females at executive level position in Ireland due to motherhood is the context for this paper. In particular, this study seeks to investigate why women's careers are impacted by childbearing. The study investigates if there is a correlation between taking maternity leave, and women's career progression in the work place. The increasing length of maternity leave benefits and flexible work arrangements results in elongated absence of females from the workplace. This leads to stereotypical role emergence by both men and women. Women take on the main responsibilities of home and child rearing, while men maintain and expand their careers. As a result, a marked absence of women exists at senior executives levels in organisations both in Ireland and internationally. Many studies have drawn attention to the challenges faced by women in reaching executive level positions in organisations. There is, however, very limited empirical research conducted with females, their co-workers, and managers, on the behaviour of women returning to the work place post maternity leave. In particular, there is a lack of research on the issues faced by individuals in Irish organisations.


Over the course of the long nineteenth century, Britain's relationship with China deteriorated from the high aspirations of George Lord Macartney's proposed diplomatic and economic partnership during the 1792–4 British Embassy, to the ignoble treaties of Nanjing (1842), Bogue (1843), and Tianjin (1858) that established Britain's imperial leverage over Chinese affairs. The Anglo-Chinese Wars (1839–42 and 1856–60), popularly known as the Opium Wars, are usually associated with Victorian, rather than Romantic, imperial practices. The military aggression exercised during the wars, as well as the treaties that concluded each conflict, typified Britain's more hostile imperial practices of the midto late nineteenth century. Accordingly, the Opium Wars appear to be ideologically removed from the preceding Romantic era's more ambiguous representations of China. Romantic literature, canonical and non, vacillated between depicting China as an established autonomous empire or as a desired conquerable territory. However, Romantic literature's participation in Anglo-Sino discourse extended well into the nineteenth century. Although historical documentation suggests clear moments wherein Anglo-Sino relations were decidedly altered (e.g., the 1842 ceding of Hong Kong Island to the British), the literary representation of British attitudes toward the Chinese continued to be more muddled, even in the midst of the Opium Wars. Romantic literature—fiction and non-fiction, poetry and prose—experienced a revival within Chinese discourse of the 1840s and 1850s, regardless of the texts' original investment in Anglo-Sino relations. Mid-nineteenthcentury writers appropriated myriad Romantic texts by incorporating them into new reflections on Anglo-Sino conflict and using them, albeit anachronistically, to develop new arguments regarding Britain's imperial pursuits in China. John Barrow's Travels in China (1804) undergoes such an appropriation in Thomas De Quincey's essay "The English Mail-Coach, or the Glory of Motion" (1849). Nineteenth-Century Contexts, 2015 Vol. 37, No. 1, 21–41, http://dx.doi.org/10.1080/08905495.2014.978491


Numerical simulation tools for solving partial differential equations have greatly improved in computational efficiency and flexibility in the past decade. As a result, today it requires relatively little effort to simulate complex industrial devices with high fidelity. This makes it possible to connect the simulation to optimization algorithms and thus support the engineering and design process for such devices. Choosing an appropriate optimizer however is not easy, since the corresponding optimization problems typically have the following features which make them hard to solve: (a) a function evaluation (i.e. running a simulation) is computationally expensive, (b) numerical inaccuracies give rise to noisy functions even in cases where the response of the physical system is smooth, and even jumps in the functions are frequent, (c) typically more than one property of the design matters, which makes the problems multi objective. In this work, we study two concrete design optimization problems: (1) Optimization of a shielding device for eddy currents where shunts have to be placed, and (2) optimization of a high-voltage insulator design. The former problem is defined on a discrete search space, while the latter is on a compact subset of a Euclidean space. On these problems, we will compare the performance of various optimization algorithms that are appropriate to cope with the features (a)-(c) above to a higher or lesser degree, including classical derivative free algorithms, local response surface based derivative free algorithms, and meta-heuristics, in particular genetic algorithms. For those algorithms which are not intrinsically multi objective, we will discuss how to use them to solve multi objective cases. Moreover, we will briefly discuss the extended setup where the optimization algorithm can select the fidelity level of the simulation, resulting in function evaluations of a higher or lower accuracy and computational costs. This adds an additional degree of freedom to trade-off speed vs. accuracy.


This report tries to give a brief overview of a number of the mathematical activities during the trimestre mentioned in the title.


This paper considers the indoor localization problem with possible non-line-of-sight (NLOS) signal propagations. Although centimeter-level accuracy can be achieved using ultrawideband (UWB) signal sources, NLOS propagation due to reflection and refraction of signals as well as multipath effect may lead to significant errors in UWB-based localization systems. To mitigate this issue, a novel and simple NLOS error compensation method is proposed in this paper, which introduces a correction factor that takes into account the influence of NLOS conditions on the UWB distance measurements. The inertial measurement unit (IMU) information are then used to correct the UWB distance measurements before passing them through a Kalman filter for data fusion. The effectiveness of the proposed approach over the state-of-the-art one is illustrated by both simulation and experiment.

Abstract This article gives an overview of the current methods for life cycle analysis with special emphasis on dynamic load analysis. Recent developments in CFD simulations of time-dependent phenomena are presented, such as the von Kármán vortex shedding at stay vanes in a Kaplan turbine and the part load vortex in the draft tube of a Francis turbine and a pump turbine. A major topic of this article is the unsteady pressure field in a pump turbine, which is caused by the interaction of guide vanes and runner blades. CFD results of the pressure pulsations and their validation through comparison with measurement data are presented. It is shown how the predicted time-dependent pressure load is transferred as input to the structural analysis of the runner. For the analysis of the response of the runner to the dynamic load knowledge of the natural frequencies of the structure is required including the influence of the surrounding water on the natural frequencies. New results of the prediction of the natural frequencies of a Francis runner including the added mass effect due to the surrounding water are presented. For Pelton runners the state-of-the-art of measurement of eigenfrequencies and detuning are discussed along with the potential improvements due to the new simulation methods.

We present a new technique for estimating speed and slip of the induction motor. The method is based on the time-frequency analysis of the current supplying the motor. Interpolated DFT, computed in the sliding time window, is used for obtaining current spectrograms with high frequency resolution. The speed and the slip are estimated from the fluctuation of amplitude of the main current harmonic. The proposed method is validated by laboratory experiment.

User's perceptions and beliefs are known for their role in technology acceptance. Studies examining the effect of cultural values along with social influence in technology acceptance are rare. They focus on various types of technologies, contexts, and types of users yielding inconsistent and contradictory findings. No studies have been undertaken to research video-conferencing usage, particularly in Jordan. This study seeks to develop a conceptual model for examining the moderating and direct effect of both individualisms versus collectivisms and power distance cultural dimensions on the relationship between social influence and video conferencing usage in Jordan. The survey method adopts questionnaires as a technique to collect quantitative data. The collected data was analysed using SPSS. The findings show that social influence has a significant direct role on increasing video-conferencing usage. Furthermore, individualisms versus collectivisms were found to increase the video-conferencing use, whilst power distance was found to decrease it. However, they do not moderate the effect of social influence on video-conferencing use. This paper has important implications on both theoretical and practical portions of video-conferencing usage in manufacturing firms in Jordan.


This paper describes a novel approach to hyperspectral imaging that is currently being implemented successfully on a small satellite. The instrument being flown is the Compact High Resolution Imaging Spectrometer (CHRIS) developed at Sira Electro-Optics Ltd. The instrument is flying on PROBA, a small agile satellite, which was launched in October 2001. The PROBA platform is flying in a Sun-synchronous polar orbit with an inclination of 97.89/spl deg/. The altitude of the platform varies over a range approximately from 553 to 688 km. The platform period is 96.8 min. The apogee of the orbit rotates around the Earth with an approximate 110 day periodicity. The main purpose of the instrument is to provide images of land areas. The platform provides pointing in both across-track and along-track directions, for target acquisition and multi-angle observations, particularly for measurement of the bi-directional reflectance distribution function (BRDF) properties of selected targets. One of the main novel features of this instrument is the provision of ground motion compensation during imaging in order to increase the integration time of the instrument, increasing the number of spectral bands that can be read and enhancing radiometric resolution. This also results in a smaller instrument, which is more compatible with small satellite dimensions.


Abstract In this paper we present an opto-mechanical sensor based on a Bragg grating as the strain-sensing element. The motivation for choosing this alternative way of strain sensing is that the sensed information is directly encoded into a wavelength, which is an absolute parameter insensitive to typical intensity and phase noise. Recently, it has been shown that fibre-optic strain sensors based on this technique are capable of resolving dynamic strain down to 0.6 × 10 −9 ( Hz ) −1 2 . To demonstrate that this new detection principle can also be used for high-performance microsensors, we have chosen to fabricate a silicon opto-mechanical accelerometer based on strain sensing by a Bragg grating in a planar waveguide. The fabrication of the accelerometer includes KOH wet etching of (110) silicon, controlling stress in PECVD glass waveguides and direct UV writing of Bragg gratings.


Picosecond infrared spectroscopy has been used to investigate electron transfer and vibrational excitation and relaxation in the mixed-valence transition-metal dimer [(NC) 5 M II CNM III (NH 3 ) 5 ] - (M=Ru, Os). Optical excitation into the metal-to-metal charge transfer band results in formation of the excited state redox isomer [(NC) 5 M III CNM II (NH 3 ) 5 ] -


SUMMARY A series of ballistic impact tests on several different instrumented tar- gets was performed to characterize the dynamic contact force hi story resulting from the impact of a compliant projectile. The results show that the variation of contact force history with impact velocity does not follow the trends pre- dicted by classical impact models. An empirical model was therefore developed to describe this behavior. This model was then used in a finite-element analy- sis to estimate the force history and calculate the resulting dynamic strain response in a transversely impacted composite laminate. INTRODUCTION As the use of composites becomes more common in modern aircraft, the per- formance of these materials under the full spectrum of loads they may encounter in advanced aerospace structural applications is of prime concern. Composite laminates are susceptible to impact damage, particularly that due to transverse impact. Bird strikes, for example, on aircraft flying at high speed and low altitude have recently proven to be extremely hazardous. Classical impact mechanics have been developed largely under the assumption of relatively stiff impactors which undergo small elastic deformations during the impact event. Energy di ssi pation and 1 arge deformations encountered during the high-speed impact of a more compliant projectile, such as a bird, limits the applicability of these classical approaches. The objectives of this work are, first, to describe a simple experimental technique that can be used to determine the force history resulting from the impact of a soft projectile. Secondly, the data taken from a series of tests will be presented, interpreted, and used to form the basis of an empirical force-history model which will be used to analyze the transverse impact of a 1 ami nated beam. In the first section of this report, a detailed description of the experi- mental apparatus and procedure is given. The next two sections outline an accurate and efficient numerical model that is used to analyze the impact experiment. The results of a simple "calibration test" are then compared with those from the numerical analysis to demonstrate the validity of the test pro- cedure. In the following section, the measured response from the impact of the soft projectile is compared to the simpler classical model, and the funda- mental differences between the two are established. An empirical model describing the contact force history due to the soft projectile impact is then devised and adapted to describe the more complicated transverse impact of the


ABSTRACT This article describes an eight-week series of caregiver meetings for African-American women caring for a parent with dementia. The meetings drew upon the Serenity Prayer, the participants' spirituality, and a problem-solving approach as major themes in an effort to help caregivers gain a greater sense of perceived control in their situations. Pre-, post- and follow-up tests indicated greater self-confidence in ability to solve difficult situations, improved well-being and happiness, as well as a positive response on the part of the participants.


In high energy physics experiments, efficient data analysis tools are required to extract interesting information from the massive data. For large-scale liquid-based neutrino experiments, neutrino signals are usually overwhelmed in huge backgrounds. By constructing a liquid neutrino detector toy model, we generate simulation data in Geant4 [1] and run reconstruction for signal background discrimination. The low-level Photo Multipliers (PMT) hits are also projected to a 2D plane to create visualization outputs for classification. With the 2D images as input, we use the Convolutional Neural Network (CNN) as a specific application, which has shown remarkable performance in signal and background discrimination and outperforms those with high-level reconstruction outputs. The method is expected to be used in the neutrino experiments such as JUNO with further study.


Background. Since 1910, a variety of radiation modalities, including radioactive isotopes, photons, and particle beams, have been used to treat prostatic cancer.


The UK-based magazine The Economist portrays globalisation as a positive extension of liberal capitalism. While consistent with the magazine's pro-market bent, the rationale for the coverage is complex, since many readers presumably share the magazine's dominant code and do not need persuasion. This paper first explores tactics used to limit discourse on globalisation to realms of economic knowledge, while devaluing knowledge from other domains. Then, using cultural theories of how people read, I argue that coverage provokes reader anxieties about a changing world--while allaying them through tales of a future in which growth continues, the lot of the poor improves, and power remains vested in the institutions, knowledge, and people that have it currently. As such, The Economist provides a utopian vision of the future and tools for shaping identity to fractions of dominant groups seeking to define their strategies in a changing world.


Based on orthogonal test method and high precision C/O spectral logging,the paper evaluates the affecting factors of determining residual oil.Through analysis of the influence of relative parameters,the major affecting factors are found: C/O has the highest affecting degree,then Si/Ca and porosity.


A study was conducted to evaluate persons' purported ability to detect hidden observers. Anecdotally, most people (87%) report that covert observation can be detected. A total of 140 college students individually sat in a room with a two-way mirror and video-monitor camera. They were told that they might be observed for any or all of the subsequent 5 min. Participants noted whether they felt a hidden observer watched them during each minute of the 5-min. session. After the session, students reported if a possible hidden observer watched via a two-way mirror or video camera or if they were not watched. Students were unable to detect observation beyond chance. Possible reasons for the persistence of the belief in detection of covert observation are posited as impetus for further research.


The influence of alkali lignin (AL) as a carbonization agent on the thermal degradation and flame retardancy of intumescent flame retardant (IFR) coating was investigated under air condition, with ammonium polyphosphate (APP) as an acid source, and melamine (MEL) as a blowing agent. Compared with a traditional APP/pentaerythritol (PER) /MEL IFR system, thermogravimetric analysis (TGA) results showed that APP/AL/MEL IFR system could induce the synergistic effect at a much boarder temperature range, and improve the thermal stabilities of the IFR coating. With the increase of AL loading, cone calorimeter test showed the peak heat release rate of the IFR coatings decreased from 54.86 MJ/m2 to 41.06 MJ/m2 .


Studies the languages that are independent of the L-prefix relation.The construction of the completion of codes are generalized as that of L-independent languages and on the other hand,the latter can be used to examine the former.In the completing process of codes the relation involved is bound up with the result of completion.It is therefore necessary to introduce various techniques into the process,and how they function can be expounded by the general construction of completion of L-independent languages.In this way a clear understanding is available to various methods of completion of codes.


Copolymers containing various amounts of acryloyl chloride were made with ethyl methacrylate, methyl acrylate, and styrene by bulk polymerization and by conversion of acrylic acid copolymers. Fibers and films of these polymers were crosslinked with ethylenediamine, and it was shown that increased crosslinking led to increased tenscity (at elevated temperature), modulus, zero strength temperature, and thermal stability and also greatly decreased elongation and shrinkage. The average molecular weight between crosslinks was calculated. The effect of crosslinking amorphous fibers and films was shown experimentally to produce materials with properties predicted for more rigid polymer structures.


In this article, two popular database connection types of mobile devices, which are Windows Authentication over IP (internet protocol) and IIS (internet information services) [1], are used and IEEE 802.11 standards, namely IEEE 802.11b and IEEE 802.11g, and GPRS/EDGE technology are evaluated with respect to query retrieval time of different number of attributes and records. In both concepts, it is obvious that a successful connection can be established, but some differences occur on query results retrieval time as the database grows. Experimental results pointed out that while using IIS connection method IEEE 802.11b has less query retrieval time than IEEE 802.11g and GPRS/EDGE, in contrast to this, IEEE 802.11g is obviously time superior than IEEE 802.11b and GPRS/EDGE while using IP connection method.


We investigate the coherent transport properties of electrons in a side terminal of a four-terminal nano device made of quantum wires with Rashba spin-orbit (SO) coupling in the presence of magnetic filed. We numerically calculate the charge and spin conductances dependent on SO coupling strength and reduced flux. The results imply that the coherent transport in this device is determined by the interplay of Rashba SO coupling and magnetic filed. For specific values of magnetic flux and SO coupling strength, a complete blocking can take place. It also shows that there is a de-blocking phenomenon induced by the interplay of magnetic flux and SO coupling. Such a 4-terminal and multi-channel structure may provide more options of controlling methods for the coherent charge and spin transport.


Suppression of the Renin-Angiotensin-Aldosterone system (RAAS) is an established intervention in the management of cardiovascular disease. Large, randomized controlled trials have provided a sound evidence base for the use of mineralocorticoid receptor antagonists to block the end product of the RAAS in the treatment of heart failure. However, the place for mineralocorticoid blockade in the treatment of hypertension is less well defined and lacking a strong evidence base. The main indication for the use of this strategy in hypertension is as a third line agent in the treatment of refractory hypertension. The most widely used mineralocorticoid receptor antagonist, spironolactone, is associated with dose related sexual side effects, limiting its use in clinical practice. Eplerenone, the selective mineralocorticoid receptor antagonist, is a promising cardiovascular drug licensed for the treatment of heart failure in Europe and heart failure and hypertension in the USA. It effectively blocks the mineralocorticoid receptor without the unpleasant sexual side effect profile of spironolactone. We review the use of eplerenone, a selective mineralocorticoid receptor antagonist in the treatment of hypertension; discuss its mechanism of action, safety profile as well as its current place in therapy.


Cancer is one of the leading causes of death throughout the world. Advancements in early and improved diagnosis could help prevent a significant number of these deaths. Raman spectroscopy is a vibrational spectroscopic technique which has received considerable attention recently with regards to applications in clinical oncology. Raman spectroscopy has the potential not only to improve diagnosis of cancer but also to advance the treatment of cancer. A number of studies have investigated Raman spectroscopy for its potential to improve diagnosis and treatment of a wide variety of cancers. In this paper the most recent advances in dispersive Raman spectroscopy, which have demonstrated promising leads to real world application for clinical oncology are reviewed. The application of Raman spectroscopy to breast, brain, skin, cervical, gastrointestinal, oral, and lung cancers is reviewed as well as a special focus on the data analysis techniques, which have been employed in the studies.


Institutional and legislation measurements together with the improvement of the education ofpupils with disabilities shaped the conditions for their access to tertiary education. The increasednumber of students with disabilities resulted in the organization and management of adaptedservices and infrastructures in order for them to ensure equal access and opportunity in educationand recreation. The purpose of the present study was to record the needs and problems in specialfacilities and services, as identified by the disabled students themselves, and compare them withthe services that the academic institutions provide in other European countries. Data collection wascarried out in three levels: a) study of the provisions made by 58 European universitiesinterconnected with the European Agency for the Development of Special Education, b) collectingdata form questionnaires sent to Greek universities and c) conducting interviews with 73 studentswith disabilities from 14 Universities regarding their needs. The content of the interviews wasanalyzed qualitatively according to the principles of Grounded Theory. The results showed that theneeds for adaptations in infrastructure can be categorized into environmental-architectural andassistive technology changes, while the provisions can be grouped into academic, administrative,social, health, welfare, culture and sport changes. At the same time significant shortcomings wererecorded at pre-university level such as early intervention, counseling, availability of specializedstaff, organized vocational orientation program and preparation for the transition to highereducation, all of which are attributed to lack of information and awareness. The conclusions lead tothe design of a facilities management model for infrastructure, services and goods to be providedby all educational institutions considering available recourses and educational priorities. This is adynamic model which is based on the communication between the Academic community andstudents with disabilities.%%%%Οι θeσµικές και νοµοθeτικές ρυθµίσeις καθώς και η βeλτίωση των συνθηκών φοίτησης µαθητώνµe eιδικές ανάγκeς διαµόρφωσαν τις συνθήκeς της πρόσβασης τους στην τριτοβάθµια eκπαίδeυση.Ο αυξηµένος αριθµός φοιτητών µe eιδικές ανάγκeς (ΦµeEΑ) eπέβαλe την οργάνωση καιδιαχeίριση προσαρµοσµένων υπηρeσιών και υποδοµών, ώστe να διασφαλιστeί το δικαίωµα τηςίσης eυκαιρίας στην eκπαίδeυση και το φοιτητικό αθλητισµό.

Boston's Computer Museum originated as a place where computer professionals could admire vintage machines and relive their industry's past. Since becoming a nonprofit educational organization and moving to its current downtown location, the museum has changed its orientation from glorifying artifacts to explaining how computers work and their impact on society. Each of its new exhibits addresses a different educational goal: "The Walk-Through Computer" explains how microcomputers work; "Tools and Toys" lets visitors try out computer applications; and "People and Computers: Milestones of a Revolution," which opened in June 1991, highlights the history of computing. "People and Computers" leaves behind the days when the museum displayed machines like sacred objects in antiseptic surroundings. With the help of an academic advisory panel, curator Gregory Welch has adopted an ambitious historical approach stressing themes such as alternative technologies and social trade-offs. The organizing principle of the exhibit is a series of nine "milestones," beginning with punch-card machines in the 1930s and moving through mainframes, minis, and micros to the 1990s. Each milestone features a historically important computer in a re-creation of its original environment, whether a Cray-1 in a British weather station or a DEC PDP-8 being used to light a Broadway show. Labels describe the way each machine was used and raise technical and social issues. The exhibit uses the interactive workstations that have become a hallmark of the Com-


This month's Focus On highlights products that can be used for reading, writing, research and other language arts-specific study. Although slanted a bit towards K-12 titles, there are still a few products here that can be used by all ages. Since we profile so many different types of software, we'll present them in no particular order. First up is Microsoft's Creative Writer 2, for Windows 95. Although it's been available for some time now, we still think Creative Writer is one of the better-designed writing tools for students ages 8 and up. Besides being a well-rounded word processor, the product also features drawing and painting tools for creating art within the program. The Picture Tools function offers over 2,000 images including clip-art, borders and background textures, and can also perform more complicated tasks such as word wraps. Perhaps the best feature for language arts instruction is the multiple story ideas offered at start-up. The software provides detailed instruction on such assignments as editing a story, changing a point of view, writing an editorial or script, and composing a poem. For Internet-enabled classrooms, Creative Writer gives various starter pages and projects such as adding HTML tags. Finally, the School Edition comes with a Teacher's Activity Guide that gives tips on integrating Creative Writer into fine arts, language arts, social studies and other curricula. Pierian Spring Software makes two writing-specific products that offer students ages 9 and up the chance to experiment with language and hone their existing writing skills. An Odyssey of Discovery: Writing for Readers and An Odyssey of Discovery: Skills for Writers both reinforce existing writing skills while encouraging budding writers to experiment with techniques such as brainstorming, using visual prompts and editing. Skills for Writers is specifically designed to help students experiment with language, assisting with word usage, vocabulary development and sentence structure. Writing for Readers teaches plot, character and setting development. Each program features various activities designed to enhance the creative thought process, is available in various configurations for labs, and aligns with NCTE/IRA standards. A Teacher's Guide is available for both titles. Broderbund antes up with a range of titles aimed at students from Pre-K all the way up to high school. In Arthur's Birthday, children ages 3 to 7 can practice their reading and word recognition skills while increasing their vocabulary. Based on the popular PBS show, the program lets kids help Arthur solve various birthday dilemmas such as matching gift tags to presents. These activities elevate the program from a simple "read-and-click" title to one that sharpens kids' problem-solving abilities. Another Living Book from Broderbund, The Cat in the Hat is available in a School Edition that features a storybook and thematic unit focused on "rainy day" activities. Various classroom activities have been developed for beginning, primary and intermediate readers, as well as second language students. In Carmen Sandiego Word Detective, students ages 8 to 14 attempt to stop Carmen and her "Babble-On" Machine, which scrambles language and turns it into gibberish. Carmen has stolen the power of speech, and you are the last agent able to stop her. Students must train for the mission by becoming proficient in puzzles that reinforce word definitions, dictionary skills and speech recognition. Teachers can also create their own word lists for students to practice with. The software's interface, like all Carmen Sandiego titles, is intuitive and highly imaginative, setting just the right atmosphere for a would-be detective. The various puzzles and mysteries really put word skills to the test in one of the most enjoyable titles we've seen for a while. Additionally, Carmen Sandiego Word Detective School Edition includes the bonus resource book Spelling Puzzles. …


The description of dynamical model of a passenger stop is given, the questions of determination of the model coefficients based on the using of temporal rows are investigated, the results of computing experiments and comparation between the computing and experimental data are discussed.


The repair of aircraft at the first line maintenance level or operational level maintenance (OLM) is becoming an increasingly significant factor in aircraft downtime and operating costs. Since the majority of these repair tasks are minor in nature, an attempt to rationalize the depth and permanency of OLM repairs is discussed. The concept suggests that most OLM repair action be rapid and maybe life limited to economize on the OLM repair effort and increase operational readiness. An added bonus for military operators through implementing an OLM rapid action repair philosophy is that base personnel will also be trained to undertake aircraft battle damage repair (ABDR) if necessary.


Picking is an intrinsically interactive procedure, and although a batch picker may prove to be a good substitute for manual picking, a subsequent interactive step will always be required. A primary goal of batch picking is therefore to reduce the time spent subsequently on QC and editing. In essence, the approach described here regards automatic picking as the identification of semblance maxima followed by a heuristic driven selection of those maxima likely to be good picks. The method assigns an overall quality factor to each peak. Using the quality factors as the basis for selection, velocity functions are then constructed from a set of "best" picks. Cumulative heuristic functions are used to guide the search towards the "best" velocity function, which is assumed to provide the picking at the current location. It is also used to define the velocity trend, which is input to the picking at the next location along the line. The method makes use of prior knowledge stored in a database, (velocity functions picked and QC'd during a previous iteration, and interpreted time horizon information). In addition, there is some scope for supervised learning.


DURING THE THIRTY YEARS from 1920 to 1950 there has been a shifting of the Negro population of the United States. What was the Negro population in 1920? Where did these citizens live? What number moved? Where did they go? What was the effect of this migration upon the states they left and upon the states where they now reside? The Census Bureau divides the United States into nine areas. The names of the areas indicate their location. Three areas accounted for 85


Abstract A simple technique is proposed that allows the definition of the geometry and characteristics of an air-jet vortex generator to be defined, using the system requirements in practical design. Typically, the aircraft designer is concerned with the mass flow-rate and air pressure requirements of any pneumatic system for inclusion to an airframe. These parameters are not congruent with those for air-jet vortex generator aerodynamic design, and therefore, some tool is required to bridge the gap. Such a tool is proposed, based on empirical methods for the prediction of air-jet vortex generator behaviour. The technique allows the comparison of the vortex strength, and the system inputs (the jet mass flow-rate and the air-jet plenum pressure) for the air-jet, for a range of jet nozzle diameters and jet velocity ratios. Through this comparison, the optimum air-jet design can be reached for a given system input.


one of the most provocative recent findings in modern medicine has been the suggestion from Barker and colleagues ([1][1]) that problems of late adulthood, such as coronary heart disease, stroke, hypertension, and non-insulin-dependent diabetes, are associated with metabolic compromise and impaired


Introduction: Policy makers in many countries are encouraging the development of integrated care strategies and the development of new models of integrated care. These new models require changes at a clinical or service level, organizational level and system level with strong leadership necessary at all three levels. Despite the key role of leadership in these efforts, there has been only limited study of what organizational leadership approach is successful in different contexts for integrated care. Theory/Methods: This paper analyses the organizational leadership behaviors and strategies in the iCOACH project (Integrated Care for Older Adults with Complex Health Needs) for 9 integrated care projects in 3 jurisdictions: New Zealand, and the Canadian provinces of Ontario and Quebec. Data are derived from interviews with leaders, policy makers and providers in these cases. We draw on institutional logics and institutional entrepreneurship theories to explore how leaders engaged external stakeholders and developed strategies to optimize the effectiveness of integrated care within and between their organizations in these different contexts. Results: There are concerted efforts to develop integrated care models of community based primary health care in all three jurisdictions. However, the policy environments vary in the latitude and resources provided to organizational leaders to develop organizational forms and networks. In Ontario and New Zealand there have been considerable variations in the nature of integrated care organizations and networks, while in Quebec the government has mandated new organizational forms and specified their relationships with other providers. Preliminary analysis of our data suggests that institutional entrepreneurship takes different forms in response to these environments, and other policy issues, such as the development of health care resources for Maori have also influenced the support and direction of integrated care. There is also variation in the entrepreneurial styles within and across these organizations, balancing the need for external stakeholder management and developing local capability for more integrated care based on the vision for the organization. Discussion: Leadership is a critical resource in the development of new organizational forms and in carrying out the negotiations needed to garner the resources and legitimacy necessary for effective organizations. However, leadership strategies can vary in different contexts, and the types of institutional entrepreneurship necessary for building these organizations varies as well. Conclusions: Understanding successful leadership strategies and entrepreneurial behaviors in different contexts helps to illuminate the similarities and differences across different policy and organizational environments. Lessons learned: While leadership is essential for integrated care, there is no single model that has been successful across the contexts we have studied. Limitations: The analysis of the data described here is still underway. Our data is derived from cases in three jurisdictions and these are likely not fully representative of the range of policy and organizational environments. Suggestions for future research: Further research on the leadership strategies that are successful in different environments is needed to confirm and extend the analysis from the 9 cases we have studied.


Abstract Staudinger reaction of 9 with triphenylphosphine gave 2,4-dihydropyrrolo[3,4-b]indole 10. Treatment of 10 with di-tert-butyl dicarbonate and 4-dimethylaminopyridine gave 11. Diels-Alder reaction of 11 with 3,4-pyridyne gave cycloadducts 12 and 13, which were converted into ellipticine 1 and isoellipticine 2. New amino analogues of ellipticine 27 and 28 were also synthesized by this new route.


A new deposition technique called "the writing method" is developed and applied to the fabrication of CdS window layer in CdSICdTe solar cells produced by the screen-printing and sintering method. Obtained CdS film is quite smooth with very few pinholes. It is also proved that this technique possesses high patterning precision. Furthermore, heat treatment of glass/CdS/CdTe substrates in H2+N2 atmosphere decreases the sheet resistance of CdS film by about one order of magn i t ude. High precision patterning ability and low sheet resistivity of CdS window realize high active/total area ratio of more than 0.8. As a result of these improvement, the 2onversion efficiency of 8. 1% in 1200cm (10. 1% active area efficiency) is obtained.


PREPARING TEACHERSAUSTIN, TEXAS-- The University of Texas's UTeach is the most visible of the new wave of teacher-preparation programs. But its success was far from preordained.


Abstract:Many organizations have transformed their business models from offering single products or service to providing IT solutions. IT solutions comprise hardware, software, and service components and are designed to solve a specific customer problem. Transforming to the IT solution business model, however, is often underestimated as it entails various challenges and risks: First, IT solution providers need to prepare for future customer engagements by building up or integrating personnel resources as well as platforms bundling software and hardware components. Second, IT solutions are highly customer-specific and providers need to interact with the customer during the entire solution lifecycle, including the design and operation of the IT solution. Third, the IT solution business model presents new risks such as operation, integration, and customer risks for providers. Building on a multiple case study with a medium-sized IT solution provider, we derive nine principles for managing IT solutions from a provider's perspective. The nine principles should be useful for CIOs and strategy-decision makers transforming their organization to IT solution providers.


We report the theoretical investigation of the coupling efficiency in presence of possible transverse and angular mismatches in case of laser diode to single-mode circular core dispersion-shifted/dispersion-flattened fiber coupling via hyperbolic microlens on the fiber tip. The study comprises first theoretical investigations of coupling optics involving the said type of coupler in presence of such mismatches. Employing ABCD matrix formalism for refraction of paraxial rays by a hyperbolic microlens on the fiber tip, we formulate analytical expressions for the coupling efficiencies in presence of the said two misalignments. Further, the lens transmitted spot size of the source should be equal to the spot size of the fiber in case of maximum coupling. In this connection, we use Petermann II spot size of the fiber in order to take care of non-Gaussian nature of field of such fibers and to make the prediction of the launch optics more realistic thereby. The investigations are made for two different wavelengths namely 1.3 μm and 1.5 μm in case of some typical dispersion managed optical fibers. Although, our simple method predicts the concerned coupling optics excellently, the evaluation of the concerned efficiencies and associated losses will involve little computations. The results present the relevant coupling efficiencies along with the tolerance with respect to the said kinds of mismatches and as such it will benefit the designers and packagers who are working in the field of optical technology.


Background In the manufacturing industry, work-family conflict (WFC) is related to working hour characteristics. Earlier studies on the relationship between working hour characteristics and WFC in the manufacturing industry have been limited to some regions in Korea. No study has addressed the data on a national scale. Thus, this study investigated the impact of weekly working hours, weekend work, and shift work on WFC using national-scale data. Methods This study was based on the fifth Korean Working Conditions Survey of 5,432 manufacturers. WFC consists of 5 variables; WFC1 "kept worrying about work"; WFC2 "felt too tired after work"; WFC3 "work prevented time for family"; WFC4 "difficult to concentrate on work"; WFC5 "family responsibilities prevented time for work". As WFC refers to the inter-role conflict between the need for paid work and family work, WFC has been measured in two directions, work to family conflict (WTFC: WFC1, 2, 3) and family to work conflict (FTWC: WFC4, 5). With these WFC variables, we conducted multiple logistic analyses to study how working hours, weekend work, and shift work impact WFC. Results Korean manufacturers' prolonged working hours increased all aspects of WFCs. Odds ratios (ORs) of WFCs based on working hours (reference of under 40 hours) of 41–52, 53–60, over 61 were 1.247, 1.611, 2.279 (WFC1); 1.111, 2.561, 6.442 (WFC2); 1.219, 3.495, 8.327 (WFC3); 1.076, 2.019, 2.656 (WFC4); and 1.166, 1.592, 1.946 (WFC5), respectively. Shift-work in the WFC2 model showed a significantly higher OR of 1.390. Weekend work 'only on Saturday' had significant ORs with WFC2 (1.323) and WFC3 (1.552). Conclusions An increase in working hours leads to the spending of less time attending to problems between work and family, causing both WTFC and FTWC to increase. As weekends, evenings, and nighttime are considered to be family-friendly to people, working on weekends and shift-work were highly correlated to WTFC.


The author points out that enterprises culture plays an important role in modern enterprise system. The human resources management is just constructed based on enterprise culture to realize rational development and management of human resources. Indifferent period of development, the enterprises will have different idea of culture, which will in turn formulate different management system of human resources. Asuccessful human resources management system is to seek for the balance between enterprise and employers, the link between enterprise's objectives and employer's individual ideal and the realization of win-win situat ion.

Many teacher education programs have adopted a cohort structure which offers attractive administrative and organizational benefits while promoting classroom community. This study examines one urban teacher preparation program that employed a cohort model. Using focus groups and survey data, this mixed methods study compared results on the basis of race and gender. Findings suggest that while the cohort structure created a strong classroom community among the majority of students, specific minority populations in the program (men and students of color) were excluded from the social benefits associated with the cohort model. This study identified active social systems of silencing and exclusion and outlines implications for hiring practices, curriculum, and faculty development.


The article deals with the problem of language neologization on the example of suffixal verbal neologisms. The author focuses on the dynamic aspect of studying the process of language neologization, in which it becomes possible to identify the dynamics of the interaction of word-formation types and their formation. Such an approach makes it possible to reveal the tendencies of the process of neologization both in a certain period of linguistic history, in the future, and in linguistic diachrony as a whole. The article considers the period of formation of the national literary language as one of the important stages of language history, since it is during this period that the language is replenished with a large number of neologisms represented by new formations and borrowings. Issues of the dynamic Dictionary of the Russian Language of the 18th century were used as the material of the study. An analysis of verbal neologisms of the 18th century made it possible to identify the most active functional-semantic fields of verbal vocabulary. A large group of new formations is made up of verbs with the general semantics of "action", formed mainly according to the word-formation model with the suffix -i-. Most of the new verbal lexicon, characteristic of the period under study, is represented by verbs with the general semantics of "activity and behavior", which were formed according to word-building models with suffixes -i-, -nicha- (-icha-), -stvova-. Within this verb group, word-formation variation is observed, which was due to the competition of word-formation models. One of the numerous groups of verbal vocabulary is the group of evolutive verbs, represented by both object verbs formed with the suffix -i- and subject verbs formed with the suffix -е-. It is noted that in the 18th century a new word-formation model with foreign language suffixes -ova- / -irova- / -izirova- was formed.

A gram-positive, chromium (Cr)-resistant bacterial strain (ATCC 700729) was isolated from ef̄uent of tanneries. It was grown in media containing potassium dichromate concentration up to 80 mg ml of the medium. The dichromate reducing capability of the bacterium was checked by estimating the amount of Cr VI in the medium before and after introduction of bacterial culture. The in ̄uence of factors like pH of the medium, concentration of Cr, and the amount of the inoculum was studied to determine the ability of the bacterium to reduce Cr VI in the medium under various conditions. In a medium containing dichromate 20 mg ml more than 87% reduction of dichromate ions was achieved within 72 h. The feasibility of the use of this bacterial strain for detoxi®cation of dichromate in the industrial wastewater has been assessed. The isolated strain can be exploited for speci®c environmental clean-up operations.


Reading is an important outcome leading to academic success in life. Young children with undetected phonological processing deficits; difficulties in naming letters, poor vocabulary and poor recognition of sight words and who do not benefit from early literacy intervention are disadvantaged. Recent developments see the rapid rise in using technology as a powerful tool in helping early literacy learners in reading and writing skills.


Biotic indices are often used to assess ecological condition using the abundance-weighted stress tolerances of taxa. Applying such indices to recent fossil records – e.g., time-averaged death assemblages (DAs) – is a promising method to (1) characterize conditions from before monitoring began, and (2) detect otherwise unappreciated strain using discordance with the living assemblage (LA). However, the robustness of regionally-specific biotic indices when applied to paleoecological data is under-explored. Here, I assess the power of three indices: Southern California's Benthic Response Index (BRI), ATZI's Marine Benthic Index (AMBI), and BENTIX. Our test material is (a) a 50-year-long dataset of macrobenthos from the Palos Verdes shelf in Southern California, sampled annually at 44 sites to monitor the effects of treated wastewater effluent, and (b) bivalve DAs from the 2008 survey. The time series was parsed into temporal bins based on wastewater treatment phases, and we calculated indices for the whole fauna, bivalve LAs, and bivalve DAs. All indices demonstrated that benthic conditions improved with remediation, and the greatest changes were close to the outfall source. Values generated for bivalves were strongly correlated to those of the whole fauna, indicating that bivalves are a strong surrogate for macrobenthic condition (second only to polychaetes when compared among other clades). Indices for bivalve DAs – which include shells >100s yrs old on this shelf – indicated less strain than was observed in early communities (1970s-80s) and either agreed with or overestimated the strain in more recent communities (2000s-10s). This live-dead discordance suggests that time-averaging causes DAs to retain a signal from pre-pollution benthic conditions that the shelf benthos is now re-attaining. Bivalve DAs, combined with long-term benthic time series data, can reveal both the existence and direction of change in ecological strain relative to historic conditions.


In this study, the melt linear viscoelastic rheological properties of polyamide 6 (PA6)–acrylonitrile butadiene styrene terpolymer (ABS) immiscible blends were analyzed with the help of Coran and fractional Zener models (FZMs) to assess the microstructure of the blends. For this purpose, dynamic shear flow experiments and scanning electron microscopy investigations were performed. The nonzero value of the elastic modulus of the spring element (Ge) of the FZM for ABS-rich blends was explained by the formation of a networklike structure because of the agglomeration of the rubber phases of the ABS matrix, whereas for the PA6-rich blends with a high content of ABS, the interactions and/or interconnectivity of the ABS dispersed phase led to a nonzero value of Ge. The value of the fitting parameter of the Coran model (f) was near to 0.5 for the 50/50 blend; this was fully in agreement with the formed cocontinuous morphology for this blend composition. On the other hand, the f value for the blends with a matrix–droplet-type morphology was near to zero for the PA6-rich blends; this indicated the lower continuity of the ABS dispersed phase as a harder phase compared to the PA6 soft matrix, whereas the f value was near to 1 for ABS-rich blends. This confirmed the formation of an interconnected networklike structure for this series of blends. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 45423.

Chemical modification is one of the most effective methods to improve the biological activity of chitin. In the current study, we modified C3-OH and C6-OH of chitin (CT) and successfully synthesized 6-amino-chitin (NCT) and 3,6-diamino-chitin (DNCT) through a series of chemical reactions. The structure of NCT and DNCT were characterized by elemental analyses, FT-IR, 13C NMR, XRD, and SEM. The inhibitory effects of CT, NCT, and DNCT against six kinds of phytopathogen (F. oxysporum f. sp. cucumerium, B. cinerea, C. lagenarium, P. asparagi, F. oxysporum f. niveum, and G. zeae) were evaluated using disk diffusion method in vitro. Meanwhile, carbendazim and amphotericin B were used as positive controls. Results revealed that 6-amino-chitin (NCT) and 3,6-diamino-chitin (DNCT) showed improved antifungal properties compared with pristine chitin. Moreover, DNCT exhibited the better antifungal property than NCT. Especially, while the inhibition zone diameters of NCT are ranged from 11.2 to 16.3 mm, DNCT are about 11.4–20.4 mm. These data demonstrated that the introduction of amino group into chitin derivatives could be key to increasing the antifungal activity of such compounds, and the greater the number of amino groups in the chitin derivatives, the better their antifungal activity was.


Applications of small unmanned aerial vehicles (UAVs) have increased steadily over the past years. Applications are found in Earth observation, reconnaissance, monitoring, and surveillance missions using imaging systems. The big advantage of radar sensors is their all-weather capability. Especially imaging radars possess several benefits over optical systems, as they are not affected by rain, snow, fog, or the time of day. The advantages using small unmanned platforms come at the cost of having to deal with restrictions on weight and volume. Hence, these parameters are the predominant design drivers for UAV sensor developments. This paper presents the concept, the technical realization and the status of a 3D imaging radar system suitable for small UAVs. ARTINO (Airborne Radar for Three dimensional Imaging and Nadir Observation) combines a real aperture, realized by a linear array of nadir pointing antennas, and a synthetic aperture, which is spanned by the moving airplane.

People are able to find rightful orders and humanity, rest and
recreation in the natures and popular cultures. As one of the
means that serve best for the purpose, we can think of park.
Today, however, people are visiting parks not only to take rest
or see natural scene, but also to enjoy themselves with amusement
activities and social gatherings there. It has been endeavored to
formulate method of area calculation and layout of the amusement
park for the country, and attempted to actually apply those
standards to the two amusement park projects at Taejong-dae and
Bomun-san which are presently under consideration.


The cerebral cortex is a complex network. It contains billions of neurons divided in spatial and functional clusters to perform different tasks. It also operates with complex dynamics such as periodic and chaotic ones. It has been shown that chaotic neural networks are more efficient than conventional recurrent neural networks in avoiding spurious memory. Inspired by the fact that the cerebral cortex has specific groups of cells, in this paper we investigate the dynamic of a recurrent neural network where neurons are coupled in such a way that form communities of a complex network. Also, we generate an asymmetric weight matrix placing pattern cycles during learning. Such a learning rule provides a natural periodic behavior in a fully connected network. Community structure breaks the connections up, forcing chaos to emerge. Our study shows that chaotic behavior rises for a high fragmentation degree in either just one community with sparse connections or several communities with few inter-community connections. For the latter case, we also show that the neural network can hold chaotic dynamic and a high value of modularity measure at the same time. These findings provide an alternative way to design dynamical neural networks to perform pattern recognition tasks exploiting periodic and chaotic dynamics.


We define several types of decomposition type non-linear integrals. These are classified by the direction of approximation(from above or below), the set family types (partition or covering) of simple functions, the coefficient signature (nonnegative or signed), and cardinal number of terms of simple functions(finite or countable infinite). We will compare these integrals considering the monotone increasing/decreasing convergence theorems.


Background: The myocardial reperfusion injury can paradoxically reduce the beneficial effects of myocardial reperfusion. We sought to detect the reperfusion injury using parameters of layer-specific myocardial deformation in patients with acute myocardial infarction (MI) after intervention therapy. Methods: Two-D speckle tracking echocardiography (2DSTE) was performed in 81 patients (mean age 57±9 years, 76 men) with acute MI after primary percutaneous coronary intervention (PCI). The peak systolic myocardial segmental layer longitudinal (LS) and circumferential (CS) strains were assessed by 2DSTE using an 18-segment model of left ventricle. The micro vascular obstruction (MVO) and intramyocardial haemorrhage (IMH) were determined by contrast-enhanced cardiac magnetic resonance imaging(ceCMR). Results: There were 422/1,458 segments with transmural necrosis in 81 patients. There were 58 patients with MVO and 46 patients with IMH. The amplitudes of myocardial layers LS and CS were significantly decreased in...

. Play is considered one of the main activities carried out by children. It is characterized by several aspects, interconnected and investigated by researchers belonging to heterogeneous disciplinary fields. With the aim of grasping the interdisciplinary complexity around the topic of play for children with disabilities, the present systematic review was conducted. Scientific studies about play for children with disabilities were searched on three databases using key words and then the included papers were analysed through a specific reading form. The scientific fields of the journal containing the article included in the review, were retrieved using the classification system proposed by the SCImago (Science Citation Index) Journal & Country Rank (o SJR indicator), a public available portal that includes national scientific journals and indicators developed by the information contained in the Scopus database. Results highlight that the theme of play of children with disabilities is covered in a variety of scientific fields, belonging from medicine to human-computer interaction, and that the most represented scientific field of the studies where education and psychology. The scientific fields seem to reconfigure their percentages in relation to the characteristics ascribable to the different investigated disabilities.


In porous media, the vacuum lifetime of ortho-positronium (o-Ps) of τ = 142 ns can be reduced markedly by pick-off annihilation (interaction with electrons of the host material). So the o-Ps lifetime is determined by the pore size which can be extracted by utilising approved models like the Tao-Eldrup model for pore sizes smaller than 1 nm and the Tokyo model or RTE model for larger pore sizes. The RTE model contains an explicit temperature dependence of the o-Ps lifetime. Experiments on controlled pore glasses (CPG) with different pore sizes (2-70 nm) at different temperatures (50-500 K) were performed to verify the RTE model. A general agreement for T = 300 K could be found. The temperature dependence of the lifetime, especially for low temperatures, could not be approved sufficiently. (© 2007 WILEY-VCH Verlag GmbH & Co.
