In recent years, indexing, classification, clustering, and anomaly detection of time series data have become topics of great interest within the database/data mining community; within those data mining applications, the measurement of similarity between two time series is one of the most essential subroutines. The superiority of Dynamic Time Warping (DTW) similarity measure over Euclidean distance for these tasks has been well-demonstrated by many researchers. However, the greater accuracy of DTW comes at a price of forbiddingly higher CPU demands. The recent introduction of lower bounding function greatly helps address this problem, making DTW calculation tenable for larger datasets.
In spite of the great success of DTW in a variety of domains, there still are several persistent myths about it, causing great confusion in the literature. This work identifies and dispels these myths by empirical demonstration of the findings with a comprehensive set of experiments. Based on these findings, a novel framework, so called Ratanamahatana-Keogh Band ( R-K Band), is proposed, making DTW faster and more accurate by learning arbitrary constraints on the warping path of the DTW calculation. This proposed framework can conveniently replace the existing DTW distance measures, or can be incorporated into any other time series applications; the extensive empirical evaluations demonstrate significant improvement both in accuracy for classification problems, and in precision/recall for a relevance feedback system for time series retrieval. As an augmentation to this work, a bit-level dimensionality reduction technique, a clipped representation, is proposed and shown to improve the compression ratio by a wide margin, while being able to maintain or increase the tightness of its lower bound, allowing even faster nearest neighbor queries, especially in ones that require DTW distance measure.


This article aims at analyzing the relation between what ghetto signifies beginning in the Christian Middle Age (the Jewish Quarter) up to the modern time (the Central-European Jewish Ghetto, the West-European labor district, the Afro-American neighborhood of North-American cities) and what the closed area (any kind of district situated in a contemporary metropolis) signifies. I have tried to analyze this relation in its evolution, approaching both the continuity, the similarity of original types of ghettoes to contemporary ones, and the discontinuity, the differences existing between the two types of ghetto. The segregation and self-isolation policies define and differentiate the ghetto in its essence. Starting from a contemporary point of view, I try to analyze the ghetto from a theoretical perspective, and from an architectural point of view.

This paper seeks to bring together three issues about which I have felt a nagging, persistent sense of unease over the past 10 years or more. They can be formulated thus: (a) Why is there a great divide between the professional debate on child abuse and that about other aspects of child care policy and practice; (b) Why is accepted good practice so often not carried out; (c) Why are the related implications of research so hard to translate into effective practice? These questions become even more pressing in the present political climate and in the context of the Implementation of the Children Act 1989.


Analyzed form outside, many actions of the economical agent seem to be impulse by the self interest. As a prototype of this kind of person we have the Homo economicus as Adam Smith described it. In a blitz portrait we identify some characteristics: he is perfect rational, perfect egoist, perfect free, perfect competitive and perfect social. The aim of this research is to permute the barycentre from Homo economicus based on self interest, to Homo generosus, based on social responsibility. As a support we have used the prison dilemma to illustrate the roll of cooperation instead self interest. This new coordination will be analyzed to the level of ethical system. Homo economicus is identified in ethics of consequences and the homo generosus in ethics of duty. In my vision, the prototype of homo generosus, is delineated under Kant's categorical imperative: respectful, based on principles as subject and sovereign.


The activity of cattle's platelets is mostly connected with the level of their metabolic processes. It is especially important at the beginning of ontogenesis and can differ in different breeds. The aim of the study is to estimate platelets' activity of healthy Holstein calves during the newborn phase. The study used 35 Holstein calves which were received from healthy cows with the normal course of in-calf state. The calves were observed and examined on the 1 st -2 nd , 3 rd -4 th , 5 th


This study develops a conceptual model that linked smart consumer experience with consumer purchase intention toward smart retail, in order to identified factors that influence consumer to make purchase at smart retail. As a viewpoint, this study employs a review of theories, knowledge, ideas, and findings in academically oriented literature, drawing upon the actual challenges in smart retail, to propose a new perspective and formulates an emerging research agenda. The research model proposes that perceived advantage, perceived ease of use, perceived enjoyment, perceived risk, perceived novelty of SRT, personalization, and interactivity drive consumer experience with smart technology in retail environment, which leads to increases in perceived shopping value and retail store loyalty. Consumer with a higher level of perceived shopping value and retail store loyalty will be more likely to develop purchase intention.

The formation of the peritrophic membrane in adult female mosquitoes, Culex tarsalis, was examined by light and electron microscopy. The initial evidence of secretion of peritrophic membrane precursors occurred at 8-12 h after ingestion of the bloodmeal. Morphogenesis of the peritrophic membrane occurred within 12-16 h after the initial secretion; culminating with a fibrous, multilayered peritrophic membrane 20-24 h after bloodmeal ingestion. A discussion of the potential participation of the peritrophic membrane in a midgut barrier to infection by arboviruses is presented. The participation of the peritrophic membrane in a midgut barrier to infection of C. tarsalis, and many other mosquito species, by arboviruses is considered a moot point.

In [1] it is shown that porous permeable tungsten-copper materials can be produced by partially infiltrating sintered porous tungsten skeletons with copper. However, this method is not suitable for the productionofmateria ls of high porosity. In the process involved, which consists of two separate operationssintering of a tungsten skeleton and its infiltration, full and even infiltration of porous parts is not easy to accomplish. A more flexible and simpler method of manufacturing high-porosity materials is to subject mixtures of tungsten and copper powders to liquid-phase sintering. Retention of High Porosity in the Liquid-Phase Sintering of Tungsten-Copper Materials As has been shown in [2], in the active solid-phase sintering of porous objects with an escaping poreforming agent their high porosity is preserved. The porous structure in this ease is stabilized as a result of a decrease in the surface tension forces acting in the large artificial pores remaining in the material after the filler has escaped from it. Apart from this, the volume viscosity of compacts with large pores is much greater than that of compacts with small natural pores [2]. It is reasonable to assume that such a coarse porous structure will be able effectively to withstand the contracting forces generated during liquid-phase sintering. In the work described below experiments were carried out on mixtures of VCh commercial tungsten powder and PME-1 electrolytic copper powder. For comparison, use was made also of mixtures whose copper component contained an addition of 20 wt.% of PNK-1 nickel. The metal powders were mixed with an ammonium bicarbonate powder of 100-g particle size, the amount of the pore-forming agent in compacts being 52 vol.%. The mixtures were pressed into compacts so that their microporosity (the porosity of theregions with fine natural pores, i.e., the pores in the volumes occupied by the metal powder) was 50%. The pore-forming agent was driven out of the compacts by heating them in a hydrogen atmosphere at a temperature of 200~C, and consequently the relative volume of the large pores formed by the filler (maeroporosity) before sintering was 52%. Thus, the compacts had a biporous structure. The liquid-phase sintering of the specimens was performed for 1 h in a hydrogen atmosphere at a temperature of 1250~ In Fig. 1 is shown the variation of the volume shrinkage and final porosity of the W-Cu and W-Cu-Ni materials with the amount of liquid phase present during sintering. As can be seen, the W-Cu material retained after sintering a porosity of 70% even at a 50% liquid-phase content. The fact that this porosity exceeded the macroporosity (52%) is evidence that during the sintering of the W- Cu material at 1250~ its microporosity, too, was largely preserved. This was presumably a result of a decrease in the contracting forces, brought about by poor wetting of the tungsten by the copper. The sintering of the W-Cu-Ni material was much more active because in this case the tungsten skeleton was wetted well by the liquid phase. As is demonstrated in [3], the presence in the binder of such a material of an element in which the refractory component dissolves leads to amarkedincreasei nshrinkage. At liquidphase contents of more than 28~c the final porosity was less than the starting macroporosity (52%), which means that even some of the large pores had begun to disappear during the active liquid-phase sintering. It should


Pictographs are often used in the media to draw attention to data that would likely be ignored in a table. In school, however, pictographs disappear from the curriculum by the middle primary years. The outcomes of the research reported here indicate that pictographs can provide a basis for rich tasks displaying not only students' counting skills but also their appreciation of variation and uncertainty in prediction. The range of responses is discussed in relation to other research and classroom implications.

Quantile regression (QR) provides an alternative to linear regression (LR) that allows for the estimation of relationships across the distribution of an outcome. However, as highlighted in recent research on the motherhood penalty across the wage distribution, different procedures for conditional and unconditional quantile regression (CQR, UQR) often result in divergent findings that are not always well understood. In light of such discrepancies, this paper reviews how to implement and interpret a range of LR, CQR, and UQR models with fixed effects. It also discusses the use of Quantile Treatment Effect (QTE) models as an alternative to overcome some of the limitations of CQR and UQR models. We then review how to interpret results in the presence of fixed effects based on a replication of Budig and Hodges's (2010) work on the motherhood penalty using NLSY79 data.

As the intellectual elite in society, scientists play a creative and pioneering role in both the exploration of the unknown world and the rationalization of social life. Their scientific careers provide ideal content for science popularization among the public. Rendering the work of scientists into stories that are popular with people is a subject that deserves special attention in science popularization. The biographies of scientists, written by historians of science and popular science writers, provide the most directly relevant sources of materials and content for communication. Biographies are commonly used as a means for studying scientists. This is the typical outcome of specialized research on the history of science and the most acceptable and readable type of history of science for the public. In general, the biographies of scientists usually involve their lives and scholarship: they are about reviewing the scientists' lives and academic growth. By reading scientific biographies, the public can access the inner world of scientists and experience the scientific spirit that underpins great scientific achievements. However, the readership of scientific biographies among the Chinese public is small. Some best-selling foreign biographies have received only a mediocre response when introduced to China. Although some high-quality biographies of Chinese scientists have also been published, most biographies are poorly written and thus have not won many readers over. At the inaugural meeting of the Department of History of Science at Tsinghua University in 2017, Yang Zhenning noted the lack of success and professionalism of works on the history of science in China and claimed that the biographical literature on scientists intended for public consumption contains some fabricated episodes. That deceptive manner of writing should be rejected. Many issues need to be addressed to create an engaging and informative narrative on the work done by scientists, and they are all closely related to scientific biographies. We focus on three aspects in this article. First, we should break the pattern of depicting scientists as saints, restore a more accurate image of scientists and build empathy with the reader. Scientists form a special group that appears to keep a distance from the public. The stereotype of scientists is closely related to the manner in which their biographies are written as well as the message that is communicated in those biographies. For example, the book Madame Curie: A Biography by Eve Curie portrays Madame Curie as a perfect woman scientist in a Hollywood-style narrative. We should note that this kind of lofty and heroic image, often encountered in the biographies of


Aberrant histone methylation regulated by abnormal histone methyltransferases(HMTs) has emerged as a critical player in the onset and progression of cancer in numerous tumor types. The reversal of aberrant histone methylation changes has therefore emerged as a potential strategy for the treatment of cancer. A number of compounds targeting these HMTs have been developed as novel therapies,in which some are in clinical trials. This review highlights the roles of some HMTs in tumorigenesis and emerging therapies being developed for the treatment of cancer.


The present study focused on the assessment of imitation performance in a large sample of 6- and 9-month-old infants from two different cultural contexts: German middle-class infants from urban areas and Nso infants from a rural area in northwestern Cameroon were tested by using age-adapted deferred imitation tasks that were varied regarding their cultural familiarity (two types of instruments each being highly familiar for one of the two cultural contexts). Within both cultural groups and without being influenced by the cultural familiarity of the instruments, infants performed more target actions in the test compared with the baseline phase, even though this difference did not yield significance in the group of 6-month-old Cameroonian Nso infants. Moreover, a higher mean number of imitated actions has been observed for 9-month-olds compared with 6-month-olds demonstrating an age-related improvement of infants' learning ability. Furthermore, at 9 months of age, German infants showed a higher level of baseline activity compared with the infants in the Cameroonian sample, which is assumed to be based on differences regarding the degree of object experiences. Results provide evidence that early in infancy, imitation is a universal learning tool in different cultural environments.


The present work investigates the behaviour of actinides (An) of different oxidation states in the process of aquatic colloid formation, e.g. at the generation of aluminosilicates (HAS) by co-nucleation of Si and Al in absence or in presence of natural humic acid (HA). The study comprises three parts. The first part of the work concentrates on the interaction of tri-, tetra-, penta- and hexavalent actinide ions with HAS colloids. The HAS colloids are synthesized through heterogeneous nucleation of Si and Al in the pH region 4 to 9 at room temperature and atmospheric pressure. Si concentration is maintained either below or above the saturation concentration of amorphous silica (2x10-3 M). In the former case 10-3 M Si is mixed with 10-5 M Al and Si is present in solution as monosilicic acid. In the latter case, 10-2 M Si is mixed with 10-4 M Al and polysilicic acid prevails in solution. The following tracer nuclides are introduced in the co-nucleation process: 241Am(III), 234Th(IV), 237Np(V) and 233U(VI). Colloids are separated from solution and precipitate by sequential filtration and ultrafiltration. Definition of the optimum conditions for the formation of colloid-borne actinide species is ascertained by radiometric assay, determining the actinide fraction in the colloidal phase as a function of pH, conditioning time, concentration and concentration ratio of the involved components. Several methods are further applied for the appraisal of the chemical binding state of actinides in the HAS colloids as well as of Al in aluminosilicate solutions: TRLFS (time resolved laser fluorescence spectroscopy), EXAFS (extended X-ray absorption fine structure) spectroscopy and ligand displacement method (using EDTA as competing ligand). The affinity for conucleation with HAS appears to follow the element tendency toward hydrolysis. The second part of the work further concerns the behaviour of An(III, IV, VI) at the interaction with humate colloids. In addition to actinide activity measurements, 14C-labelled natural humic acid is used in order to facilitate the tracing of humic colloids behaviour. The conditions of colloid formation are investigated by radiometric assay as a function of pH (6.6-7.8), time, concentration of HA (0.6-8 mg/L), Al (1x10-5-1x10-4 M) and An (5x10-8-1x10-5 M). The generation of humate-colloid-borne species is distinctively favored for the non-hydrolyzed ionic species. Generation of humate-colloid-borne An(IV, VI) is enhanced by increasing HA concentration or decreasing the An/HA concentration ratio. The third part of the work follows the conditions for formation of colloid-borne An(III, IV, VI) in the mixed system containing the competing HAS and humic colloids. The simultaneous presence of HAS and HA generally enhances the stability region (in respect with pH and Si/Al concentration) of the colloid-borne An species. The formation of mixed HAS-humic colloids with synergic binding appears to be responsible for the stable incorporation of An into the colloidal phase, as ascertained for Cm(III) by TRLFS. Such a synergic effect is assumed to be related to the two different and complementary mechanisms exhibited by the HAS and HA colloids in binding the actinides.


Plastic waste is a solid that is difficult to decompose but can turn into environmental microplastics. Microplastics are sizes between 0.1 μm–5 mm, highly prolific anthropogenic pollutants affecting terrestrial, freshwater, and marine ecosystems. The purpose of this study was to determine the ability of Babylonia spirata to accumulate and eliminate polystyrene microplastics. This experiment uses the nuclear applications technique. The experiment consists of two methods: manufacturing microplastics and biokinetics. The manufacture of microplastics labeled Zn-65 is based on the reaction of polystyrene sulfonate with zinc to form polystyrene sulfonate Zn resin. This microplastic labeled Zn-65 is very stable in the aquatic environment, so it is used for bioaccumulation experiments. Biokinetics includes acclimatization/adaptation of the organism for seven days, bioaccumulation consists of the organism accumulating microplastics labeled Zn-65 for seven days, and depuration for seven days that were placing the organism accumulating microplastics labeled Zn-65 in water free of contamination and biokinetics calculations include the BCF (Biocontration Factor), ku (uptake constant), ke (depuration constants), and t1/2 (half-life). The experimental results show that the ability to bioaccumulate polystyrene microplastics from seawater (BCF) is 79.2 to 304.31 ml.g-1. This bioaccumulation is affected by the microplastic content in the water. The biological half-life of the microplastic is 14.54 to 41.78 d. There is a relationship between the concentration and the Ku, Ke and BCF. the polystyrene content. The experimental results show that microplastics bioaccumulate in a marine organism so that they can move through the food chain and are ultimately harmful to humans.


Background: The complex interaction of human, vehicle and environmental factors along with a lack of sustainable preventive programs has contributed to the "silent epidemic" of traumatic brain injuries (TBI). TBI poses a grave threat to the quality-of-life (QOL). Aim: The aim of the present study was to examine the effects of neurofeedback in QOL in patients with TBI. Materials and Methods: Pre- and post-interventional study design was adopted. Sixty patients, 30 in the intervention group (IG) and 30 in waitlist group with the diagnosis of TBI in the age range of 18-49 years were assessed on QOL scale, after obtaining the informed consent. Patients in the IG were given 20 sessions of alpha-theta neurofeedback training (NFT), 5 sessions / week. Statistics Analysis: Descriptive statistics, Spearman's correlation, Mann-Whitney and Chi-squared test was used. Results and Conclusion: Patients in the IG showed statistical improvements in QOL post post-neurofeedback. Results are encouraging for the incorporation of NFT into treatment programs for patients with TBI in improving QOL.


Although there are some methods for constructing structural vector autoregressive (SVAR) models, there are fewer statistical methods for identifying and diagnosing the structural form of the model. This means that there is no way to confirm contemporaneous causal order even if the model seems satisfactorily estimated. We therefore propose some tests for identifying and make diagnoses of the structural form of an SVAR model. The proposed tests use the (inverse) covariance matrix of the error of the reduced form of the VAR models, where the errors are possibly uncorrelated but non-independent. Monte Carlo experiments illustrate the finite sample performance for the proposed test. The proposed tests apply to the effects of the quantitative easing policy by the Bank of Japan for the period January 2009 to December 2014.

Recent advances in sequential data modeling have suggested a class of models that combine recurrent neural networks with state space models. Despite the success, the huge model complexity has brought an important challenge to the corresponding inference methods. This paper introduces an structured inference algorithm to efficiently learn such models, including variants where the emission and transition distributions are modelled by deep neural networks. Our learning algorithm leverages a structured variational approximation parameterized by stochastic models and recurrent neural networks to approximate the posterior distribution. Experimental results on synthetic datasets have demonstrated the promising performance of the proposed method. In addition, our method has significantly outperformed the current state-of-the-art methods on music and speech modeling tasks.


We have all encountered patients with caries and other dental issues and discussed with the patients and caregiver the importance of dental visits and brushing their teeth. What else should we be doing?


Both ileostomies and colostomies, whether fashioned as a loop or an 'end', are 'iatrogenic' herniae created with all good intent. Ileal conduit herniation is a common problem when the trephine is raised through the belly of the rectus muscle, and thus we enjoyed reading the outcome of the Swedish audit by Styrke et al. [1], where a sublay mesh was placed prophylactically to lower its frequency. We note that in 58 patients the clinical incidence of herniation was 14% at 3 years' follow-up. This is certainly much lower than the traditionally documented rates of 27–48% [2,3]. Indeed, some surgeons have attempted to lower the frequency of this complication but to date they have been thwarted despite some novel ideas [4]. As stated by the authors [1], paracolostomy herniation is also a common problem and with this in mind the lateral rectus abdominis positioned stoma (LRAPS) technique to colostomy formation has been described [5]. The aim of this dissection is to minimize disruption of the layers of the anterior abdominal wall, preserving the complete width of the rectus abdominis muscle. The important steps in the dissection [5] include avoiding cruciate (no vertical) incisions in the rectus sheath and creating the trephine above the 'arcuate line' of Douglas that defines the lower edge of the posterior rectus sheath. These steps and bringing the stoma lateral to the rectus muscle (but still within the linea semilunaris) all reduce the theoretical risk of later trephine widening (Figure 1). This approach to ileal conduit formation was used by one urologist (ACC) in 47 consecutive patients undergoing radical cystectomy for malignancy over a 6 year period. There were 37 men, with a mean age of 66 years (range 37– 82 years), and the patients' mean body mass index was


ABSTRACT This study combined service quality (SQ), corporate social responsibility (CSR), satisfaction, and trust as antecedents of corporate reputation (CR) to examine how these constructs concurrently influence a hotel's corporate reputation and subsequently customer loyalty and citizenship behavior using data collected in May 2021 on 222 US leisure travelers who stayed at mid- to upscale hotels over the previous two years. Using structural equation modeling (SEM), results revealed that while CSR positively influences a hotel's CR both directly and indirectly (through satisfaction and trust), SQ only exerts an indirect influence (again through satisfaction and trust) on a hotel's CR. Furthermore, CR has a positive influence not only on customer loyalty but also citizenship behavior. These results contribute to our understanding of the antecedents and consequences of hotel corporate reputation (CR), and help further demystify relationships among the tested variables, providing both theoretical and practical implications.


Due to balance of external and internal force capacities a variation quasistatic problem has been solved in the paper. The problem allows to determine optimum values of α and β angles in the accepted field of sliding lines when destruction pressure takes on a minimum value p min . It has been ascertained that the minimum pressure p min which is necessary for destruction of a corrosion layer is registered at stream compression coefficient λ = 0,063 and the pressure is equal to 8-17 MPa for the investigated speed range v = 80-140 m/s.


This report maps vocational routes into education and training upon completion of compulsory education in the UK. It is based on recent cohorts of the England and Wales Youth Cohort Study (YCS). Cohort members are surveyed for the first time when they finish compulsory education at age 16 or 17 and again at yearly intervals up to the age of 18 or 19. This report mostly relates to 16-17 year olds surveyed at the beginning of 2002 and analyses that track young people over time relate to the two-year period between the beginning of 2000 and 2002. The report provides information on many aspects of vocational pathways after completing compulsory education including: (1) the proportion of young people who work for vocational qualifications after age 16; (2) the balance between vocational qualifications and full-time education and work-based training; (3) recent trends in the take-up of vocational qualifications; (4) the kinds of young people who choose vocational qualifications; (5) vocational qualifications achieved in full-time education and government support training (GST); (6) differences within GST in qualifications aimed for and training received; (7) length of stay in GST and the factors that affect this; and (8) dropout rates from vocational qualifications during the first postcompulsory year and the factors linked to dropout. Some key findings at the beginning of 2002 were that: a third of 16-17 year olds had a vocational qualification as their main study aim; three quarters of those taking vocational qualifications were in full-time education and just under a fifth were in GST with very few in ordinary jobs; the proportion of 16-17 year olds taking vocational qualifications was smaller in 2002 than in 1989, partially due to a decreasing proportion of the age group in work-based training but also affected by curriculum policy reforms; in the cohort as a whole, one in seven 16-17 year olds who started working for a vocational qualification after the end of Year 11 had dropped out by the beginning of the following year and most of these gave up studying for qualifications altogether.

The supply response of Australian housing has not been commensurate with the growing demand. Four main factors affecting the Australian housing supply are house completion time, cost of finished house, customer preferences and level of skilled labor. Off-site manufacturing (OSM) could become a key innovation for the future of Australian house building as it provides capacity in meeting the growing housing demand, green construction and lesser requirements for labor force. OSM is a modern construction method in which house building components are produced in offsite factories and then transported to the construction site to be assembled. The supply responsiveness of OSM can be enhanced by employing lean and agile concepts. In this study, four leagile strategies are introduced to facilitate decision making based on different combinations of housing supply factors. This paper presents a matching of the four strategies with the four studied factors in the Australian house building using Analytical Network Process (ANP). The data employed for the ANP model derived from the actual specifications of 258 houses built in five Australian States by five major house builders in Australia. The results from the ANP model show the suitability in applying each strategy under different degrees influenced by the factors tested.


A woman, aged forty-eight years, came to the clinic complaining of loss of weight and appetite over a period of nine months. She had had a severe attack of typhoid fever at the age of eighteen, but for many years had enjoyed excellent health. From November, 1924, to May, 1925, she had nursed an aged relative and was under an unusual strain. About February, 1925, she commenced losing weight. In seven months she lost 30 pounds. About May her appetite failed; she had no food intolerance, but food did not appeal to her and she ate less. There was no apparent loss of strength. For fourteen years she had experienced a sensation of pressure over the gall-bladder area. At times she thought she could palpate a mass. There was never any jaundice, nausea, or emesis. During the last week before coming to the clinic she suffered daily attacks of cramps in the upper abdomen, lasting for a few hours. Physical examination elicited some fullness in the right upper abdominal quadrant, with rigidity of the right rectus musc...

Abstract : The Army is currently embarking on a major peacetime modernization program. As the drawdown comes to a close, the Army is about half its former size and is confronted with a far more complex strategic environment. Virtually any place the Army may be employed, it will be at the end of a long. line of communication with its CONUS sustaining base. Furthermore, the Army will have to be wary of simultaneous challenges to United States interests in other theaters. As a result, the Army must be capable of quick decisive victories with minimal casualties in spite of its smaller size. In order to ensure that the Army is able to meet this standard in its future wars, the Army's leadership has set in motion a modernization plan aimed at maximizing the potential power of a smaller but more lethal army. This modernization plan places a heavy premium on the integrative technologies, (computers and communications), to get more of its forces into the fight at the right time and place and at an ever increasing operational tempo. One by-product of this plan is an increasing dependence on the electromagnetic spectrum to collect and move information on the 21st century battlefield.


The use of gasoline for primary energy consumption can reduce crude oil, contained in the earth. The development of alternative fuels such as biogas and biofuel is very critical to overcoming this problem. Biogas requires purification to remove some contaminant particles that interfere with the combustion process. The packed column is generally applied to absorb and separate gas and liquid mixture. It is more efficient due to the liquid flows down the column of steam naturally without the supply of energy from outside the system. This study focuses on determining the effect of the packed column biogas purification process. Biogas is applied as an alternative fuel in spark-ignition engines (SIE). The test is carried out using a chassis dynamometer to obtain power and torque data. The use of the packed column for biogas fuel purification can produce higher performance compared to unrefined biogas. The unrefined biogas still contains impurities that can interfere with the combustion process. This condition is proven by measuring the power and torque of the vehicle on the chassis dynamometer, where the filtered biogas produces higher power and torque.
Tests were carried out both using the packed column and without the packed column. Variations from speed to torque, to power, to SFC and BMEP are considered. In this study, validation is in good agreement with previous studies. Overall, the results show that the average error between using the packed column and without the packed column for torque, power, SFC and BMEP is increased by approximately 7 %. Purification of biogas using the packed column using Ca(OH)2 can bind CO2 and obtain pure methane gas with a higher heating value.
In conclusion, the packed column for biogas purification as fuel for motorcycle injection systems can be applied

Quantum channels, also called quantum operations, are linear, trace preserving and completely positive transformations in the space of quantum states. Such operations describe discrete time evolution of an open quantum system interacting with an environment. The thesis contains an analysis of properties of quantum channels and different entropies used to quantify the decoherence introduced into the system by a given operation. Part I of the thesis provides a general introduction to the subject. In Part II, the action of a quantum channel is treated as a process of preparation of a quantum ensemble. The Holevo information associated with this ensemble is shown to be bounded by the entropy exchanged during the preparation process between the initial state and the environment. A relation between the Holevo information and the entropy of an auxiliary matrix consisting of square root fidelities between the elements of the ensemble is proved in some special cases. Weaker bounds on the Holevo information are also established. The entropy of a channel, also called the map entropy, is defined as the entropy of the state corresponding to the channel by the Jamiolkowski isomorphism. In Part III of the thesis, the additivity of the entropy of a channel is proved. The minimal output entropy, which is difficult to compute, is estimated by an entropy of a channel which is much easier to obtain. A class of quantum channels is specified, for which additivity of channel capacity is conjectured. The last part of the thesis contains characterization of Davies channels, which correspond to an interaction of a state with a thermal reservoir in the week coupling limit, under the condition of quantum detailed balance and independence of rotational and dissipative evolutions. The Davies channels are characterized for one-qubit and one-qutrit systems.


In this paper a 'FPGA cluster' based framework for high performance Cryptanalysis has been proposed. The framework abstracts underlying networked FPGA cluster into a unified acceleration resource. It does so by implementing requested amount of computation kernels (crypto-graphic modules) and managing efficient distribution of the network bandwidth between the inter-FPGA and intra-FPGA computation kernels. Further agile methodology for developing such networked computation kernels with use of a high level language (Python) based HDL library and seamless integration with a user space crypt analysis application have been discussed. 40bit partial key attack over AES256 has been demonstrated as a capability demonstration. Performance higher than clustered CPUs and GPUs at lower costs and power is reported. Keywords-FPGA; cryptanalysis; cluster; framework; high performance computing;

In the study, CE-QUAL-W2 was used and its examination and correction were conducted targeting 2001 and 2003 when the condition of rainfall was contradicted. Using the proved model in 2003, a scenario was implemented with management of locations for dewatering outlets and actual data for dam management in 1987 when inflow and outflow level were almost same. In case of the scenario which the location of dewatering outlets was 5m higher than usual location, exclusion efficiency for turbid water inflow at the beginning of precipitation was good. In case of the scenario which the location of dewatering outlets was 10m lower than usual location, exclusion efficiency for excluding turbid water remained in a reservoir after the end of precipitation. However, the scenario applying dam management data in 1987, exclusion efficiency was relatively low. In the scenario, power-generating water release spot at EL.57m for first four days after the beginning of precipitation, EL.52m for 5th to 8th and EL.42m from 9th days. An analysis of the scenario reveals that both excessive days exceeded 30 NTU and average turbidity levels were decreased comparing before and after the alteration on outlets. The average turbidity levels were decreased by minimum of 55% to maximum of 70% and 30NTU exceeding days were decreased by 45 days at maximum. Also, since it could exclude most of turbid water in a reservoir before the destatifcation, the risk for turbid water evenly distributed in a reservoir along with turn-over could be decreased as well.


Existing helmet-mounted detection methods for cycling electric vehicles in network models have many parameter quantities and calculation quantities. In order to further improve the above parameters, the study puts forward a light test method for helmet on the basis of the improvement of YOLOv5 to form a lightweight and high-precision detection model. First of all, the DSConv module is instead of the Conv in the C3 module, which reduces parameters and calculated amount, thereby further improve the lightweight model. Secondly, adding the SE attention mechanism to filter unrelated information and solve information overload, so that allow the structure to focus more on vital information. Then replace the neck structure in YOLOv5 with the improved Effcient-RepGFPN structure to complete the feature fusion process. Meanwhile, this method uses EIoU loss to obtain more accurate box positioning and improve the precision of bounding box regression. After the network is improved, comparative experiments are carried out with various algorithms. Finally, the ablation experiment of the improved method is carried out on the constructed dataset to continue testing the validity about test model. Through the experiment to prove that this method makes mAP increased by 1.68%, the quantity of parameters is reduced to 68.77% of the unadorned algorithm. Meanwhile, reduce the amount of calculation to 52.53% and reduce the inference time.


The Gas-cooled Fast-Reactor (GFR) is one of the system developed in the frame of the 4th generation of nuclear plants. The helium coolant may contain some residual oxidizing impurities that can oxidize the cladding material. A sandwich material with a metallic layer (Ta or Nb) inserted between two sheets of SiC/SiC composite is a promising cladding system of the nuclear fuel to support mechanical strengths, to retain fission products without blocking the neutrons. Nevertheless SiC may support active oxidation with production of gaseous SiO and CO and sublimation in accidental conditions for temperatures above 2000 K, so the aim of the following study is to firstly investigate the oxidation resistance of the metallic liner in extreme conditions, alone and then covered by the SiC/SiC composite. The High Pressure and Temperature Solar Reactor (REHPTS) was implemented at the focus of the 6 kW Odeillo solar furnace in order to reproduce in helium atmosphere the sudden and huge temperature increase that can occur in the case of a nuclear accident. XRD and SEM enabled to observe that the high temperature exposure favored the (211) preferential orientation of tantalum and that the amorphization of niobium occurs above 1500 K. Such changes may impact the properties of the cladding elements. Some sandwich materials made of one plate of metal covered with a SiC/SiC composite were also tested and a carburation of the metallic plates at 2200 K was observed.


By using the methods of qualitative description and quantitative description, this paper compared the compilation characteristics of "plane vector" content in three versions of high school mathematics textbooks in mainland China and Taiwan from the aspects of content structure, style column, content breadth, and depth. The People's Education A version has a strong inquisitiveness; the Beijing Normal University version highlights the subject compatibility and the student subjectivity; and the Hanlin version emphasizes the mathematics knowledge intuitiveness and correlation. Thus, it is suggested that the construction and compilation of high school mathematics textbooks in China need to integrate and link the internal relationship between mathematical knowledge and the design and compilation of mathematics textbooks based on core literacy.


Accidents involving underground rail transport were analyzed to quantify the magnitude and operational requirements for individual mine car braking systems. The results showed that the brake preventable accidents represent only 2% of the total underground fatal accidents and less than 1% of the total underground nonfatal accidents. In addition, brake preventable accidents are expected to decline over the next decade. The costs of accidents involving deaths and injuries were determined using various well-accepted methods. The costs of a brake retrofit program for all operating underground coal cars were developed separately for small and large coal mines. Costs of retrofit brakes, new car brakes, maintenance, inspection, and repair facilities were included in the estimates. The analysis showed that a retrofit program would not significantly increase safety, and that the program cost would greatly exceed the corresponding expected benefits.


Several trade agreements include occupational health and safety regulations but there are many barriers to implementation. Mechanisms for sanctions are often weak but the lack of political will is the biggest barrier.


Exploring the difference between "stable" and "robust" touches on essentially every aspect of what we instinctively find interesting about robustness in natural, engineering, and social systems. It is argued here that robustness is a measure of feature persistence in systems that compels us to focus on perturbations, and often assemblages of perturbations, qualitatively different in nature from those addressed by stability theory. Moreover, to address feature persistence under these sorts of perturbations, we are naturally led to study issues including: the coupling of dynamics with organizational architecture, implicit assumptions of the environment, the role of a system's evolutionary history in determining its current state and thereby its future state, the sense in which robustness characterizes the fitness of the set of "strategic options" open to the system; the capability of the system to switch among multiple functionalities; and the incorporation of mechanisms for learning, problem-solving, and creativity.


A potential origin for the reported discrepancies on the low‐temperature photosensitivity of particle‐induced anion antisites in GaAs is revealed by a systematic study of the relative fraction of photoquenchable paramagnetic As4+Ga centers as a function of neutron fluence and annealing temperature. The electron paramagnetic resonance data show that the As4+Ga centers can be split into two subsets.


Horizontal and vertical distributions of algal species and occurrence of phytal animals on the algae were investigated in the kelp bed, Laminaria religiosa, at Iwanai on the southwestern coast of Hokkaido, Japan, in June, 2001. A belt transect (1 m wide) was put on the sea floor from 0 to 250 m out from the shore line, and algae found along the transect were identified and counted. Laminaria religiosa was mostly abundant between 2 m and 140 m from the shore line, coverage recorded there being over 50%. Phytal animals on L. religiosa and other 13 algal species were collected by net (1 mm mesh) at a distance of 20 m from the shore line and a depth of 1.5 m. Forty-seven species were collected on 14 algal species, including 6 species of gastropods, 3 bivalves, 10 polychaets, and 25 crustaceans. The lacunid gastropod Temanella turrita was the dominat species on most of the algae. Species diversity of phytal animals was highest for Dictyota dichotoma (number of species occurring= 22), followed in order by Symphyocladia latiuscula (21), Polysiphonia morrowii (17), and Sargassum confusum (17). The poorest phytal species diversity was recorded on L. religiosa. The degree of similarity in phytal animal species composition between the algal species was calculated by Kimoto's C11 index, and cluster analysis was done by UPGMA method. Three clusters were recognized, L. religiosa alone, a cluster formed of 11 algal species with a phytal fauna dominated by Temanella turrita, and a cluster formed of 2 algal species with a phytal fauna dominated by crustaceans.

"ABSTRACT. Introduction: Sports activity interferes with physiological growth, adaptability accelerating and perfecting structural, functional and mental differentiation. The performance model is dependent on the total capacity of the players, on the psycho-social system resulting from the perfection of the executive functions, of the morphological, physiological, informational and decisional subsystems. Objective: The objectives underlying this work are the discovery and determination of the relative age effect (RAE) that leaves its mark on the system of failure or success in the lives of athletes, basketball players. By following the birth months of the athletes of a certain year, we try to prove that there is a close connection between the age advance in the life of certain athletes and their career succes. The premise of the study is to analyze the impact of the RAE effect in the U16, U18 and U20 categories of the Romanian junior women's basketball teams. Material and method: In order to demonstrate a connection within this subject, the method used was the structuring of sportswomen in several age categories and the analysis of their results. Results: According to the conducted study, the existence of the relative age effect among the selected ones is found, but not in the way that those born in the first months of the year would have a substantial advantage. Conclusions: The results confirm the fact that there is a possibility for the younger ones to evolve with efficiency similar to their older colleagues."


We present a three-dimensional (3-D) printed metallic K-band (18–26.5 GHz) passive front end for satellite communication. It is intended to be used as a unit cell in a large antenna array. The proposed front end is composed of a two-stage $1 \times 4$ power divider, rectangular-to-circular waveguide tapers, and a linear four-element conical antenna array, which are too complex to be fabricated by a traditional machining process in a whole piece. Taking advantage of the 3-D printing technology in realizing complex structures, we achieve a highly integrated passive module. A good agreement is achieved between simulation and measurement. The proposed front end has impedance bandwidth 19–21 GHz, the maximum gain of 15.5 dBi at 21 GHz, and desirable radiation patterns on both E- and H -planes. The influence of fabrication tolerance like the surface roughness and dimensional tolerance are observed and analyzed. Compared with traditionally fabricated metallic microwave passive devices, the proposed work has a shorter turnaround time and a lower cost. Compared with dielectric 3-D printed microwave devices, it features more simplicity in terms of process and better physical robustness. It opens up new possibilities for microwave device fabrication.


Development of modern integrated circuit technologies makes it feasible to develop cheaper, faster and smaller special purpose signal processing function circuits. Digital Signal processing functions are generally implemented either on ASICs with inflexibility, or on FPGAs with bottlenecks of relatively smaller utilization factor or lower speed compared to ASIC. Field Programmable DSP Array (FPDA) is the proposed DSP dedicated device, redolent to FPGA, but with basic fixed common modules (CMs) (like adders, subtractors, multipliers, scaling units, shifters) instead of CLBs. This paper introduces the development of reconfigurable system architecture with a focus on FPDA that integrates different DSP functions like DFT, FFT, DCT, FIR, IIR, and DWT etc. The switching between DSP functions is occurred by reconfiguring the interconnection between CMs. Validation of the proposed architecture has been achieved on Virtex5 FPGA. The architecture provides sufficient amount of flexibility, parallelism and scalability.


This review relates the knowledge of Yuval Harari's Work to Education. The book highlights human development through processes that progressively required less manual effort, allowing time and energy to be directed to cognition. Two brands became evident: the ability to collaborate with similar ones and the tendency to eliminate different ones. The Cognitive Revolution, between 70 and 30 thousand years ago, underpins our complex capacity for language and fiction, enabling coexistence in large groups of humans. We have made ourselves and our societies complex, and there is ample evidence that the greater the diversity and complexity of an ecosystem, the more it can resist threats. However, our historical course has often been in favor of homogenization. Thus, thinking about the focus of education and how to learn to live with the richness of diversity is thinking about the quality of individual lives and also about the future of the human race, as one.

Abstract : Travel-time tomography was used to obtain the lateral variations in P(n) velocities and P(n) velocity azimuthal anisotropy beneath the Basin and Range Province. We used 1226 P(n) arrivals from 184 earthquakes recorded by 113 stations. The tomographic image shows the lateral variation in P(n) velocity from 7.9 km/s in the northern Province to 7.6 km/s in the southern Province. Azimuthal variations in P(n) velocities are less than one percent as determined from the travel time residuals after taking out the contribution of the lateral velocity variations of the P(n) tomography. Although the standard errors of the azimuthal variations are about two percent, there is no reason to believe the existence of the P(n) azimuthal anisotropy in the uppermost mantle beneath the Basin and Range Province. Beghoul and Barazangi's (1990) suggestion of more than three percent azimuthal anisotropy is the result of the lateral heterogeneity and mantle velocity gradient Before tomographic inversion, we refined the P(n) travel times by considering the lateral variations in the crustal thickness and velocities in the region based on the numerical experiment and theoretical development given in this paper. These refinements are crucial in obtaining an accurate velocity image. (MM)

In a number of quasi-one-dimensional organic metals the dependence of the magnetoresistance on the direction of the magnetic field is quite different from the predictions of the Boltzmann transport theory for a Fermi liquid with a scattering rate that is independent of momentum. We consider a model in which there are large variations in the scattering rate over the Fermi surface. The model is the quasi-one-dimensional version of the "cold spots" model introduced by Ioffe and Millis to explain anomalous transport properties of the metallic phase of the cuprate superconductors. The dependence of the resistance, in the most- and least-conducting directions, on the direction and magnitude of the magnetic field is calculated. The calculated magnetoresistance has a number of properties that are quite distinct from conventional transport theory, such as magic angle effects and a significant magnetoresistance when the field and current are both in the least-conducting direction. However, the model cannot give a complete description of the unusual properties of (TMTSF)(2)PF6 at pressures of 8-11 kbar.


Whether the neutrino mass ordering is normal or inverted remains an experimentally open issue in neutrino physics. The knowledge of neutrino mass ordering has great importance for neutrinoless double-beta (0 νββ ) decay experiments, which can establish the nature of massive neutrinos, i.e., whether they are Dirac or Majorana fermions. Recently, the KamLAND-Zen 800 measurement has reached for the first time the parameter space of the inverted ordering with a vanishing lightest neutrino mass. By assuming the inverted ordering, we attempt to derive the physical information of the neutrino nature and Majorana CP phases from a negative or positive observation of 0 νββ decays in the near future. Moreover, the possibility of extracting the nuclear matrix element in the case of a positive observation is also exam-ined.To avoid the ambiguity from unknown priors of neutrino masses, we adopt the maximum likelihood method instead of the Bayesian approach usually considered in previous works.


The development of a trip distribution model requires a massive data collection task, such as expensive travel surveys to identify trip makers' origin and destination zones. Intra-zonal trips are usually ignored in the development of trip distribution models because of the difficulty associated with measuring travel costs. However, ignoring intra-zonal trips leads to incomplete model estimation especially when the zone size is large, and thus, the number of intra-zonal trips is substantial. This is especially important, with the growing interest around the world on creating more walkable and bikeable cities where a high share of those trips is intra-zonal. In this paper, we use mobile phone data to derive country-wide mobility trends. A set of doubly constrained trip distribution models that integrates intra-zonal trips was estimated for 123-district-level traffic analysis zones. We present two approaches to estimate the intra-zonal travel costs measured in terms of trip distance. Our analysis reveals that the average intra-zonal trip distances obtained from the two approaches provide different levels of sensitivity to the distance-decay effect. Our result also shows that model estimation in the absence of intra-zonal trips produces biased estimates.


SUMMARY The asymptotic distribution of the order of an autoregression selected by a generalization of Akaike's FPE criterion is given. Some of the properties of the distribution are investigated. The use of this criterion is illustrated by a simulation study.


In this paper, a method to calculate the probability of lightning attaching in an area-of-interest of any polygonal shape and based on Lightning Location System (LLS) data is described. The calculation is based on previous work in which the equations necessary for calculating the probability of lightning attaching in an area are described. By combining this approach with some of the techniques used in Gaussian smoothed maps, it is possible to make these calculations for areas of any polygonal shape. From this, area-of-interest probability maps can be developed and a case study involving a damaged solar panel is presented as an example.


We formalise the problem of query reformulation over a description logic ontology and a DBox in a general framework. This framework supports deciding the existence of a safe-range first-order equivalent reformulation of a concept query in terms of the signature of a DBox. A constructive method to compute the reformulation is provided. We are particularly interested in safe-range reformulations since they can be transformed to relational queries and executed using SQL. We also discuss the completeness of the proposed framework with respect to finite and unrestricted models. As a case study we consider ontologies and queries expressed in SHOQ.


Hyperkalemia is a rare condition after the dietary intake of large amounts of potassium. It may be more likely to occur in patients with impaired renal function and multiple drug use. Since potassium disorders lead to cardiac effects, life-threatening cardiac arrhythmias may occur when they are not recognized or treated. We detected hyperkalemia in the patient who came to our emergency department with a complaint of nausea. The anamnesis of the patient was detailed, and it was learned that the patient had excessive consumption of bananas with diet. It should be borne in mind that there may be problems with excretion of potassium in the elderly and patients with additional diseases. Treatment of our patient in the emergency department was started early and potassium was reduced to normal limits. Dietary intake should be questioned in addition to kidney dysfunction in all patients with hyperkalemia.

Results of an architecture study of four Heavy Lift Launch Vehicles (HLLV) families are summarized, with attention given to civil, commercial, military and Space Exploration Initiative (SEI) applications. The Mars Exploration architecture is used as the SEI model baseline, and the architecture of each vehicle family is analyzed with respect to ground processing, launch operations, on-orbit operations, mission performance, and cost. For lunar missions, a 70-t earth-to-orbit (ETO) vehicle is shown to have definite cost advantages, with only small operational disadvantages, if the lunar program is small or medium in size. For Mars, a comparison of 150-t and 250-t ETO vehicles shows that little operational advantage is gained by going to the 250-t size.


A neutron scintillation detector based on high-pressure 4He has been developed and tested. The detector responds to elastic scattering of unmoderated fast neutrons, preserving neutron energy, position, and timing information. Neutrons from three different sources, AmBe, 252Cf, and from the ambient background, have been measured with clearly distinct energy spectra. Exposing the detector to different levels of gamma radiation up to 1 mSv/h from a 60Co source has demonstrated that gamma exposure does not affect neutron detection performance within measurement statistics. Applications in the field of radiation portal monitoring are discussed.


Let E be an elliptic curve over a finite field k, and l a prime number different from the characteristic of k. In this paper, we consider the problem of finding the structure of the Tate module Tl(E) as an integral Galois representations of k. We indicate an explicit procedure to solve this problem starting from the characteristic polynomial fE(x) and the j-invariant jE of E. Hilbert Class Polynomials of imaginary quadratic orders play an important role here. We give a global application to the study of prime-splitting in torsion fields of elliptic curves over number fields.


In traditional centralized application construction and data storage modes, the application servers and the users are not in equal position in user information management. The application server can store and abuse the user's information under the circumstances that the users are not aware, and the user cannot revoke the authorization from the application server. Therefore, this paper proposes an identity management system combined with blockchain technology, which can return the management right of user information to users. This system adopts a three-layer architecture composed of blockchain layer, virtual chain layer and storage layer, and encapsulates all functions in each layer. It has good flexibility, and is easy to add new technologies, with good extensibility. The blockchain records the user's information state to realize the consensus and integrity of the user's data. The virtual chain layer is responsible for the main logical functions and encapsulates the user's request into a blockchain transaction, maintaining a good portability. The storage layer is responsible for the actual file storage and is responsible for file routing, backup, and query. Comprehensively speaking, based on the above three layers' architecture, the system implements the user's privacy granularity control, the user file's external storage, and combines the zero-knowledge proof to update the user's private key. In view of the application environment of this system, the access time delay and efficiency of the P2P storage system are simulated. It solves the problems of centralized application construction and data storage mode under which users cannot fully control personal information and privacy protection.


Is there a tension between solidary behavior of employees and temporary employment relationships within modern organizations? Research into the effects of temporary employment relationships on employee behavior has rendered inconclusive results. Some researchers argue that temporary employees will show less solidarity because of their exchange relation with the organization while others emphasize that temporary workers may show more cooperation because they want to acquire a permanent employment status. Empirical research shows mixed findings as well. The question is addressed if these inconclusive findings can be accounted for by examining the social context of temporary and permanent employees. The effects of two features of the social context in which interactions between individual employees take place are examined: (1) temporal embeddedness, referring to the extent to which there are ongoing interactions between two actors and the likelihood that they will meet each other in the future; and (2) network embeddedness, referring to the extent to which a relationship between two actors is part of a larger network of relationships. The empirical studies are based on empirical data from four different sources: a survey among university employees, a survey among employees in different organizations, a vignette study, and a dataset consisting of coded ethnographic data. The analyses of the empirical data leads to three main conclusions. First, it is shown that solidary types of behavior are reciprocal; within organizations horizontal and vertical solidarity relationships are present. The second conclusion is that solidarity from employees is affected by the past and future of relationships and that temporal embeddedness is not just a matter of relationship length but depends crucially on the quality of the past between employees. The third conclusion is that solidary behavior of employees is positively affected by formal as well as informal network embeddedness, but that employees that are at the same time formally and informally dependent of others show less solidarity.


A brief summary of the problems in protein structure prediction is give at first,then united residue force field is introduced and based on this force field energy minimization of Ac-Ala19-NHMe and the 10-55 fragment of the B-domain of staphylococcal protein A is carried out.The energy of staphylococcal protein A fragment before and after are respectively -81.31822 kcal/moland -144.8705 kcal/mol,which justifies the validity of UNRES.


Overcurrent protection by sensing the top switch current with the peak current limiting or the bottom switch current with the valley current limiting in a buck converter is analyzed and the analysis is extended to other topologies. It is investigated that the auto soft restart "hiccup" current limiting may never be tripped while the cycle-by-cycle current limiting is employed as lower current limiting threshold, and that with the valley current limiting the overcurrent level is uncertain depending upon circuit parameters and operating conditions. Finally, experimental data was collected and presented to confirm the analysis


Properties of nuclear levels in 151Sm have been studied by measuring angular distributions for the 152Sm(d,t)151Sm reaction and spectra at several angles for the 152Sm(3He,α)151Sm and 150Sm(d,p)151Sm reactions. The reaction products were analyzed with a magnetic spectrograph and detected with photographic emulsions. Transfer l values were deduced from the (d,t) angular distributions and from the ratios of (3He,α) and (d,t) cross sections. The (d,t), (d,p), and (3He,α) reactions on targets of 151Sm were also studied in order to learn more about the wave function of the 151Sm ground state. The low-lying positive parity levels can be described by the Nilsson model with Coriolis and ΔN = 2 interactions included. However, the properties of the low energy negative parity states could not be explained as easily. No mixture of Nilsson states was found which could simultaneously explain the single neutron transfer intensities and the Coulomb excitation probabilities from previous measurements.

Abstract Incorporation of 2′-deoxy nucleotides into tRNA is described using two complementary strategies: (a) in vitro transcription with a mutant T7 RNA polymerase and (b) enzymatic ligation of chemically synthesised tRNA fragments. The former permits incorporation at a low to a moderate substitution level for all nucleotides while the latter allows a complete exchange of ribonucleotides to deoxynucleotides as well as incorporation of point mutations. Both methods can be used for studying the influence of 2′-hydroxy groups at specific positions important for tRNA aminoacyl synthetase recognition.


We consider beam equations of the form with boundary conditions corresponding either to a simply-supported or a clamped beam. The function α is supposed to be nonnegative and we assume that the underlying linear problem has zero as its first eigenvalue. We give a unified treatment of the existence of solutions for both boundary conditions, using variational or degree-theoretic methods.

0,05), from F-test result indicated that PER, EPS and ROE simultaneously had the
effect on the shares prices. While the t-test result indicated that PER and EPS had
the significance. This case meant that PER an EPS partially had the significance
effect on the share price. While thee result it could be know that ROE partially had
no effect on the share price.


The following article features the contents which indicate the outline of issues related to the category of 'integral upbringing' undertaken in the perspective of family pedagogy. They can be placed in two areas. The first one is focused on issues concerning integral development of family members and the special contribution of family to human development and integral upbringing. Conventionally speaking, it can be assumed that it is a direct subject of pedagogical reflection concerning the reality as well as the nature of married and family everyday life. The second area involves the questions about 'the category of integral upbringing' in the structure of family upbringing theory in the process of building knowledge about family.


Tourism in China is currently still in the agglomeration stage,but with an increasing trend towards clustering.Increasing returns and rising transaction cost,brought about by specialization and division of labor,are the key to forming clustering in tourism.Therefore,in order to development tourism in China,we should eliminate market barriers and expand market size on the basis of division of labor within the industry.We should also strengthen legal system,regulate competition and diversify the demand of tourists.


This article proposes a theoretical-methodological approach for the modelling and creation of entrepreneurial ecosystems, a notion that dominates in current entrepreneurial literature. Drawing upon the extant literature on ecosystems and their complexity in different contexts we focus on Manizales Mas, an entrepreneurial ecosystem in Colombia, to discuss it as an artefact of fourth order design. At present, the relevant literature and theoretical insights are summarised while appropriate methodology for future research is discussed. The study aims at connecting the general notion of 'ecosystem' with entrepreneurial ecosystems in a precise way for further empirical research.


Aql X-1 was observed in a Low Intensity State (LIS), a state that is usually characterized by high optical but low X-ray flux. Our daily monitoring of the source using the 1.3m telescope in Cerro Tololo Inter-America Observatory operated by the Small and Moderate Aperture Research Telescope System (SMARTS) was used to trigger a series of target-of-opportunity (ToO) observations of the source using the Rossi X-ray Timing Explorer satellite (RXTE). The X-ray colors and temporal variability studies suggest that the source was in a powerlaw dominated state featuring high rms variability in the lightcurve and dominance of hard photons during this LIS. The ToO observations were continued until the source made a transition to the canonical thermal dominated or high/soft state.


A new algorithm for constrained molecular dynamics is proposed. In contrast to the standard approach, the constrained bond-length/bond-angle value is adjusted at each time step so that total energy is minimized with respect to the constrained distances. This can be viewed as modifying the equilibrium bond-length/bond-angle according to external and centripetal forces. Two approaches are constructed to implement the algorithm. Method I includes all energy terms, but it is neither holonomic nor symplectic. Method II neglects a rotational kinetic energy term, resulting in a more expensive symplectic integrator. Both integrators are reversible and well conserve total energy. Due to the iterative nature of the optimization, which requires an energy evaluation at each iteration, these methods are intended for use in conjunction with other integration techniques that require an optimization at each time step iteration, such as the self-consistent electronic polarization methods or iterative combined quantum mech...


Marvelous Protestantism: Monstrous Births in Post-Reformation England, by Julie Crawford. Baltimore and London: The Johns Hopkins University Press, 2005. Pp. x + 270. Hardcover $50.00. Reviewer: GRACE TIFFANY In newly Reformed England, through the sixteenth and seventeenth centuries, the popular printing press birthed a many-bodied, inky monster: hundreds of illustrated pamphlets and books declaring the shocking, prodigious arrivals of strangely deformed babies in the nation's villages and towns. Investigating this low-cultural print phenomenon, Julie Crawford discovers how stories and pictures of the "monstrous births" served a variety of (mostly) Reformed Protestant purposes. Whether the births were real or fictional, their stories and images were turned by the pamphleteers-and by at least one Puritan preacher-into symbols of a moral distemper which their commentators presented as national, social, religious, or all three. Crawford deftly demonstrates that the brunt of these stories' attacks was borne by women, whose alleged lecheries or blasphemies (often both) were thought physically to have imprinted themselves on their offsprings' bodies. Thus "[i]n many popular pamphlets . . . the headless child is both a symbol and a product of its mother's lack of patriarchal guidance" (118). Such pamphlets fused the Pauline instruction to women to submit to their husbands' headship with the frightening quasi-medical suggestion that pregnant women's imaginations and moral behavior could affect their unborn children. "Discreet women, and such as desire to have children, will not give eare unto lamentable and fearefull tales or storyes, nor cast their eyes upon pictures or persons which are uglie or deformed, least the imagination imprint on the child the similitude of the said person or picture," Crawford quotes a French physician as saying in a treatise published in London in 1612. The cruel irony of such admonitions for women is apparent. No doubt the anxieties of the pregnant were exacerbated in early modern England by pamphlets warning mothers-to-be not to contemplate the monstrous babies and behaviors vividly represented in those very pamphlets. The "imprint" of imagination, indeed! (In her acknowledgments page Crawford lets it be known that she finished the book while pregnant herself, and I admire her nerve.) One wonders about early modern Englishwomen's responses to the pamphlets, as well as about the continuing fortunes of the unlucky babies-some of whom must have really existed and even survived-and the subsequent lives of their parents. Real early modern families, however, are not the subject of Crawford's book, whose critical eye focuses mainly on the monstrous texts themselves, not on those folk whose misfortunes helped inspire them. Thus her study is sensational in two senses of the word. It yields, in lucid and compelling prose, an impeccably researched and fascinating account of an important early modern textual and social phenomenon, and is thus a wonderful work of cultural scholarship. It is, at the same time, a book that reproduces-in verbatim quotations of the pamphlets' "monster" descriptions and in more than forty illustrations, including a big green beast on the cover-the lurid, often apocalyptic warnings of the Reformers whose project it coolly examines. "Most people," Crawford states in her conclusion, "neglect books and stories that are not 'Somewhat antick and extraordinary'" (185). That final sentence implies that Marvelous Protestantism, like the writings it dissects, was structured to appeal to the popular appetite for grotesque images and tales. It does, which is not to say it doesn't also appeal to the intellect. "Antick and extraordinary" though Crawford's book is, its serious informative purpose is not undermined but vitally served by its colorful excursions into over one hundred textual (most can't be called literary) accounts of prodigious births. The titles of these works range from the should-be-shocking ("The Holy Sister's Conspiracy against their Husbands" [239]) to the mildly reassuring ("Dies Novissimus, or, Dooms-day Not so Near as Dreaded" [238]) to the wonderingly verbose ("The most strange and wounderfull apperation of blood in poole at Garraton in Leicester-shire, which continued for the space of foure day es, the rednesse of the colour for the space of those foure dayes every day increasing higher and higher, to the in finet amazement of many hundreds of beholders of all degrees and conditions, who have dipped their handketchers in this bloody poole, . …


Morals are an important element that must be owned by every Muslim person, but the decline in morality has an impact on today's era so that moral awareness and lack of knowledge about morality in everyday life decreases. So it requires a deep understanding of morality. Therefore, it is necessary to re-learn the important points about morality by studying them through exemplary stories that have been contained in the Qur'an. In the Qur'an QS. Al-Qashhash there is a story of Qarun from there we can see some lessons about morality and moral values contained in his story. This study aims to determine the moral values contained in QS. Al-Qashhash in the story of Qarun and to find out the important vocabulary contained in it, then study the relevance of moral values to human behavior in everyday life. The focus of this research refers to qualitative research methods and literature by taking primary data from the Qur'an and books of interpretation along with other explanations with hadiths and books related to the discussion of morality and the story of Qarun. To analyze the data, this research explains it through the method of tahlili interpretation and interpretation of the vocabulary contained in the Qur'an. The results obtained by this study are, knowing the important vocabulary about moral education contained in the treasure story in QS. Al-Qashhash, then we can understand what moral values are contained in the story of Qarun in order to understand moral education and then from there we can see its relevance to human behavior in everyday life.


Proteins from lucerne juice were fractionated using iso-amyl alcohol, n-butanol, iso-butanol, ethyl acetate, diethyl ether, iso-propanol, ethanol and acetone, with % concn. ranging from 4 to 26 (v/v). Optimum pH for fractionation was 6.0-6.4. Yield of cytoplasmic leaf protein concentrate (LPC) decreased with increase in solvent level; with isoamyl alcohol, cytoplasmic LPC yield was max. (1.63 g/100 ml extract) at 10:0.40 (v/v) concn., whereas with ethyl acetate max. yield (1.51 g/100 ml extract) was at 10:0.75 (v/v) concn. Those solvents having limited water solubility brought more protein into the cytoplasmic fraction than water miscible solvents. Cytoplasmic protein concentrates did not have a green colour.


Amidst the euphoria of the November revolution it was even claimed2 that, if the charmonium model correctly described the newly discovered resonances, one would have found "the hydrogen atoms of strong-interaction physics, for it [would] then be possible to subject the gauge theory of strong interactions to fairly st;ingent tests in a reasonably simple setting. Much of hadronic physics could then be related to charmonium spectroscopy as molecular spectra are related to that of hydrogen." Since then, essentially all the predictions of the charmonium model have been confirmed. Furthermore, nature has been far more generous than anyone expected ·during the winter of 1974-5: it has given us a second massive positronium-like system, the 1', and there is no doubt that its spectrum 7 is both richer and simpler than that of charmonium. It is therefore legitimate to ask whether those optimistic expectations have been fulfilled. Before I address myself to this question, I recall the basic conceptions that underlie the charmonium model, and summarize the present experimental situation. As it is our objective to assess the validity of quantum chromodynamics (QCD), I assume, for the moment, that it is the correct theory of strong interactions. QCD is characterized by one essential dimensional parameter A, which for our purpose will be a typical dimension of hadrons, say Arv 0.6 fm, or Arv 1/3 GeV. Quarks then fall into two categories: light quarks, with effective masses smaller than or comparable to A, i.e., u, d ands; and heavy quarks Q, having masses large compared to A, i.e., c and b. Non-Abelian gauge theories are asymptotically free: in contrast to quantum electrodynamics (QED), the coupling to the gauge field decreases if the invariant mass of a virtual-field quantum grows large compared to A. This assures us that perturbation theory converges rapidly in any hadronic process arising from space-time regions with dimensions small compared to Aand involving only light quarks. Under these circumstances, one can use the invaluable intuition gleaned from QED. This perturbation picture fails in two regimes; one failure is rather trivial, the other very profound. The obvious breakdown is near any threshold for producing hadrons that contain Qs


We report on the detection of MAXI J1820+070 (e.g. ATel #11399, #11418, #11420) with the Low-Frequency Array (LOFAR). Observations in the high band (115-189 MHz) were carried out from 2018 April 27 02:32:33.0-04:32:33.0 UTC (MJD 58235.106-58235.189).


This paper relies on a microsimulation framework to undertake an analysis of the distributional implications of the COVID-19 crisis over three waves. Given the lack of real-time survey data during the fast moving crisis, it applies a nowcasting methodology and real-time aggregate administrative data to calibrate an income survey and to simulate changes in the tax benefit system that attempted to mitigate the impacts of the crisis. Our analysis shows how crisis-induced income-support policy innovations combined with existing progressive elements of the tax-benefit system were effective in avoiding an increase in income inequality at all stages of waves 1-3 of the COVID-19 emergency in Ireland. There was, however, a decline in generosity over time as benefits became more targeted. On a methodological level, our paper makes a specific contribution in relation to the choice of welfare measure in assessing the impact of the COVID-19 crisis on inequality. © 2021, O'Donoghue et al.


On April 13, 2005 the Federal Aviation Administration (FAA) implemented revised Standard Instrument Departure (SID) procedures at Atlanta HartsfieldJackson International Airport (ATL). The procedures utilize Area Navigation (RNAV) capabilities that enable point-to-point navigation largely independent of ground-based navigational aids, providing greater flexibility in route design and operations. Implementation and usage of RNAV procedures leverages flight automation systems currently available on most Instrument Flight Rules (IFR)operated aircraft in the National Airspace System (NAS). The implementation of RNAV procedures at ATL has delivered increased departure efficiency, i.e. more efficient utilization of available runways and constrained airspace surrounding the airport. This paper outlines the design of ATL's RNAV departure procedures and the results of comprehensive evaluations of operational data. This paper describes the analysis methodology developed to evaluate operational changes using radar data, and presents preand post-implementation comparisons of several key benefit metrics: departure efficiency, the distance departing aircraft fly in terminal airspace, and the climb continuity of departing aircraft. The results show that ATL realized gains in departure efficiency while reducing the distance aircraft fly in its terminal airspace. The results also indicate that potential exists for further distance benefits in a planned future implementation.


In the present work, we studied the agricultural production system adopted by small producers in irrigated area, identifying the papaya productivity and quantifying water usage in culture. Irrigated agriculture area corresponds to the irrigated perimeter Curupati, located in the municipality of Jaguaribara/CE. Evaluations of irrigation systems was held. To characterize the moisture in the irrigated area of soil profile effected up collections in layers of 0-30; 30-60; 60-90 and 90-120 cm. It was observed that Distribution Uniformity Coefficient CUD showed a value of 94,20% as well as an Application Efficiency Ea of 84,78% considered satisfactory. The moisture contents of 90 120 cm are compatible with the other studied profiles, which featured an excessive use of water and fertilizer in an area out of reach of papaya root system. The productivity varied of 80 ton ha(minimum) to 106 ton ha(máximum), with an average productivity of 96,78 ton ha-. The average productivity found in this study exceeds the average productivity found for papaya cultivation in other regions of Brazil.


—This paper describes progress towards creating an integrated large-scale visual and RGB-D mapping and localization system to operate in the MIT Stata Center. The output of a real-time, temporally scalable 6-DOF visual SLAM system is used to generate low fidelity maps that are used by the Kinect Monte Carlo Localization (KMCL) algorithm. This localization algorithm can track the camera pose during aggressive motion and can aid in recovery from visual odometry failures. The localization algorithm uses dense depth information to track its location in the map, which is less sensitive to large viewpoint changes than feature-based approaches, e.g. traversing in oppo- site direction up and down a hallway. The low fidelity map also makes the system more resilient to clutter and small changes in the environment. The integration of the localization algorithm with the mapping algorithm enables the system to operate in novel environments and allows for robust navigation through the mapped area—even under aggressive motion. A major part of this project has been the collection of a large dataset of the ten-floor MIT Stata Center with a PR2 robot, which currently consists of approximately 40 kilometers of distance traveled. This paper describes ongoing efforts to obtain centimeter-level ground- truth for the robot motion, using prior building models.


The pandemic of coronavirus 2 (severe acute respiratory syndrome (SARSCoV-2) has significantly changed lives around the world. Musculoskeletal symptoms can develop with SARS-CoV-2 as with other respiratory infections. Viral infections can be cause of arthritis, but the spectrum of symptoms can be quite wide, from arthralgia to chronic arthritis. Coronaviruses can be usually cause of arthralgia and myalgia rather than clinical arthritis. However, a syndrome of dysregulation and systemic overactivation of the immune system, described as a cytokine storm or hyperinflammatory syndrome, can developduring the course of COVID-19. As a result, coagulation and inflammation can significantly affect the progression of the disease and possibly lead to damageof the musculoskeletal system.The aim of the publication is to raise the awareness of rheumatologists and general practitioners, we offer a clinical case of the development of a musculoskeletal system lesion in a patient with COVID-19 and the successful treatment of this condition in this patient.Patients and methods. The article presents a clinical case of patient Z., who was diagnosed with joint lesions on the background of coronavirus infection.The patient was hospitalized in the rheumatology department of the Communal Non-profit Enterprise of the Kharkov Regional Council «Kharkiv RegionalHospital».Results and discussion. The patient underwent a full range of clinical and diagnostic studies and was prescribed systemic therapy with corticosteroids,supportive, as well as antibiotic therapy. The decrease of joint damage symptoms was noted during therapy. Subsequent observation was indicatedan improvement in the patient's condition after the end of treatment in hospital.Conclusions. Our own experience in the treatment and management of the patient with a lesion of the musculoskeletal system against the background of coronavirus infection presens in the article. The data on clinical cases that were accompanied by joint damage against the background of COVID-19 or occurred some time after a viral infection were presented. Important practical clinical issues related to the diagnosis and management of patients withatypical manifestations of the disease are considered.
