We develop an abstract framework for obtaining optimal rates of mixing and higher order asymptotics for infinite measure semiflows. Previously, such results were restricted to the situation where there is a first return Poincar\'e map that is uniformly expanding and Markov. As illustrations of the method, we consider semiflows over nonMarkov Pomeau-Manneville intermittent maps with infinite measure, and we also obtain mixing rates for semiflows over Collet-Eckmann maps with nonintegrable roof function.

The Japanese industry is still suffering contraction as a result of the recession, but activity remains strong and several innovations and developments are reported. A brief survey of other Asian countries suggests that most are experiencing extremely rapid growth, not all of which is linked to the automotive industry


Otto Preminger's Laura opens with a voice‐over which establishes the whole film as the discourse of an absent narrator. In itself this is not unusual—the use of such narrators was standard practice in 1940s Hollywood—but Laura complicates matters by having the narrator die before the film comes to an end and the voice‐over return as a radio broadcast within the final scene. This essay explores the logic of this unusual enunciative scenario, demonstrating how its apparent contradictions are caught up in a consistent movement, and focusing throughout on the way the question of enunciation relates to the occurrence of the film. In doing so, it offers an account of Laura which foregrounds the fact that the film happens, using the occurrence as a means to understand elements of the film which might otherwise appear problematic. More generally, it offers a reconfigured account of the problem of filmic enunciation which understands that problem to be a matter, first and foremost, of filmic ontology.


The problem of detecting a constant signal in nearly Gaussian skewed noise is studied in this paper. Sensitivity of both the linear detector and the sign detector are examined. It is shown that the performance of the linear detector deteriorates when the noise distribution becomes skewed. On the other hand, the sign detector appears to be less sensitive to the noise skewness. Furthermore, a modification of the linear detector is proposed. This modified scheme, when the noise skewness measure is small, will behave almost like the linear detector in Gaussian noise.


Mechanisms for training pool skills have evolved from manually setting up balls in different positions on the table and hitting them one-by-one to now using technology to precisely set up these plays and practice the game virtually. The aim of this study was to investigate how adding haptic feedback into a pool video game affects transfer of training into real-life pool skills. A 2 x 4 mixed factorial design was used to see how haptic feedback (its absence or presence) and four types of shots affect pool performance. Half of the participants experienced the pool video game without haptic feedback while the other half experienced it with haptic feedback. Performance before and after the video game practice was recorded as successful or unsuccessful, with a series of the same 40 pre- and post-video-game shots. Results from 38 participants are presented, and their implications are discussed.


For future quantum technologies the combination of a long quantum state lifetime and an efficient interface with external optical excitation are required. In solids, the former is for example achieved by individual spins, while the latter is found in semiconducting artificial atoms combined with modern photonic structures. One possible combination of the two aspects is reached by doping a single quantum dot, providing a strong excitonic dipole, with a magnetic ion, that incorporates a characteristic spin texture. Here, we perform four-wave mixing spectroscopy to study the system's quantum coherence properties. We characterize the optical properties of the undoped CdTe 1 ar X iv :2 20 1. 00 79 2v 1 [ co nd -m at .m es -h al l] 3 J an 2 02 2 quantum dot and find a strong photon echo formation which demonstrates a significant inhomogeneous spectral broadening. Incorporating the Mn2+ ion introduces its spin-5/2 texture to the optical spectra via the exchange interaction, manifesting as six individual spectral lines in the coherent response. The random flips of the Mn-spin result in a special type of spectral wandering between the six transition energies, which is fundamentally different from the quasi-continuous spectral wandering that results in the Gaussian inhomogeneous broadening. Here, the discrete spin-ensemble manifests in additional dephasing and oscillation dynamics. Introduction The incorporation of individual quantum systems into solid-state platforms,1–6 their coherent control, and interfacing them with external degrees of freedom7–10 is a key for implementation of quantum technologies. One of such promising platforms are semiconductor quantum dots (QDs),11 which owing to constant progress in the epitaxial growth12,13 and chemical synthesis,14 have now reached a tremendous structural quality.15 In parallel, processing of this material has been driven virtually to perfection permitting advanced engineering of the light-matter coupling with photonic structures.9 As a result, QDs in photonic microstructures serve as compact sources of single photons for quantum cryptography.16 Conversely, optical or electrical control of single quantum states confined to a QD is challenging, nonetheless intensely pursued in fundamental research.17–20 Over the last decade, a major progress has been achieved in measuring21–23 and controlling24–26 the coherence of optical transitions attributed to the bound electron-hole pair, forming a QD exciton. This was achieved by performing coherent ultrafast nonlinear spectroscopy,27 in particular four-wave mixing (FWM) on photonic devices hosting InGaAs QDs. However, the exciton radiative lifetime T1 lies typically in the nanosecond range, thus setting the upper bound for its coherence time T2 ≤ 2T1. Although an exciton represents an efficient interface between light and matter, its short T2 limits its usage as a qubit. Hence, a promising perspective


One of the main topics in genomics is to determine the relevance of DNA variations with some genetic disease. Single nucleotide polymorphism (SNP) is the most frequent and important form of genetic variation which involves a single DNA base. The values of a set of SNPs on a particular chromosome copy define a haplotype. Because of its importance in the studies of complex disease association, haplotyping is one of the central problems in bioinformatics. There are two classes of in silico haplotyping problems, i.e., single individual haplotyping and population haplotyping. In this review paper, we give an overview on the existing models and algorithms on this topic, report the recent progresses from the computational viewpoint and further discuss the future research trends.

The apparent and direct electron excitation cross sections of both the 1s/sub 2/ and 1s/sub 4/ levels of Ne are measured using laser-induced fluorescence. The experiment utilizes radiation trapping to maintain appreciable level populations. The direct excitation cross section for the 1s/sub 2/ level has a peak value of 1.0 x 10/sup -17/ cm/sup 2/ at 65 eV; the direct excitation cross section for the 1s/sub 4/ level has a peak value of 8.8 x 10/sup -19/ cm/sup 2/ at 65 eV.


Most discussions about notions of authority and dissent in early modem Europe usually imply those embedded in Christian traditions, whether Protestant or Catholic. To address these same issues from the perspective of Jewish culture in early modem Europe is to consider the subject from a relatively different vantage point. The small Jewish communities of the fifteenth through seventeenth centuries were shaped in manifold ways by the norms and values of the Christian and Moslem host civilizations to which they belonged. Yet, they were also heirs to powerful rabbinic religious and political traditions that structured their social relationships and shaped their attitudes towards divine law, human responsibility, communal discipline, and authority. To examine their universe of discourse in its proper context is to view it both in its own cultural terms and in its dialogue and negotiation with the non-Jewish world. No period in Jewish cultural history has undergone more radical reformulation and revision by recent scholarship than the early modem; though to what extent conventional schemes of periodization like "early modern," "Renaissance," or "baroque" can be meaningfully applied to the Jewish cultural experience is a question which still engenders much discussion and debate.' Equally problematic is a proper evaluation of the kabbalah, the traditions of Jewish mystical and esoteric experience,


The C-V characteristic curves are measured on LPE-grown (p) Pb_(0.8)Sn_(0.2)Te-(n)
PbTe heterojunction diodes, and the net donor concentration profiles of PbTe epitaxial
layer near the junction region are calculated thereby. The net donor concentration (N_0)
at the edge of space-charge region in PbTe epitaxial layer at zero bias is found to be
strongly dependent on LPE growth temperature (T_(ep)), possibly due to the interdiffusion
of native defects during the LPE growth process.


This paper introduces the concept of place defending and articulates its implications for locality based social policy. Place defending is the protection of one's local area from unfavourable assessments, in this case of being labelled or perceived as a racist space. Place attachment and identifications with place are drivers of place defending. Person place relationships and their implications for locality based social policies have not yet received sufficient consideration in the literature a significant oversight considering the current policy focus in Australia and the United Kingdom on locality based social policy. In this study of local anti racism in the Australian context, place defending involved the denial of racism and performances of place that reproduced the discourse of tolerance. Print media coverage of the release of national data on racism was analysed alongside a series of interviews with individuals working on anti racism at both local and state/federal levels. Four tools of place defending are discussed: direct action to defend place; spatial deflections; use of minority group members to discredit claims of racism; and critiques of those who make claims about racism. The tools of place defending operated to construct localities as places of tolerance, potentially undermining the case for anti racism.


This article focuses on the paratexts of opera DVDs as a route into the status and cultural placement of opera videos in contemporary visual culture. In particular, it analyses the picture covers, menus and openings credits of four productions of Verdi's Don Carlo, arguing that, although the videos fall within the broader discourse of the 'televisual' (a discourse that encourages the viewer to conceive the image as a transparent document of the performance on-stage), these paratexts put forward alternative ways of conceiving the relationship between medium and subject matter, imagining opera's materials, however briefly, in terms of narrative cinema and music video, video games and computer loops.


We studied undercoverage and nonresponse in a telephone questionnaire survey (original N = 7,000) in Groningen, Netherlands. Bivariate and multivariate analyses showed that the undercoverage was strongly related to all sociodemographic variables studied, except sex. Nonresponse was related to age, country of origin, marital status, and household size and composition, but not to sex, unemployment, dependence on social assistance, and education (only known for the unemployed). Both undercoverage and nonresponse contributed to a strong middle-class bias in the final data set: middle-aged and older economically secure persons of Dutch origin living with a partner are overrepresented, while persons of lower social status, the young, people of foreign stock, the unemployed, persons living on welfare, and singles are underrepresented. 4 Tables, 1 Figure.

An oversimplified notion is that DPOAEs originate from a restricted region on the basilar membrane (BM). In actuality, DPOAEs are a distributed process involving the interaction of many wavelets, most likely generated over a broad region at, and basal to the overlap place of the primary tones. In the present study, DPOAEs were measured in rabbits as time waveforms by using phase rotation to cancel all components in the final average, except the 2f1-f2 DPOAE. At times, f2 was turned off for 6 ms producing a gap so that the DPOAE was no longer generated. These procedures allowed the DPOAE onset as well as the decay during the gap to be observed in the time domain. Results showed that complexities emerged near the onset of the DPOAE time waveform as the f2/f1 ratio decreased, and at the beginning of the gap when f2 was turned off. Such complexities were unaffected by interference tones (ITs) near the DPOAE. However, these complexities were removed by ITs presented above f2, which can be explained by the inte...

Fifty years have passed since those memorable researches of the young German physicist, Heinrich Rudolph Hertz, which have come to be regarded as the starting point of radio. For it was he who first detected, and measured, electromagnetic waves in space — waves which had been predicted, it is true, but which had never before been observed. It is not to be claimed, of course, that the radio art would have failed to be born were it not for his genius, for we know that almost simultaneously the experiments of Lodge in England were pointing with certainty to the same discoveries, and the speculations of others were revolving around the possibility of generating electric waves. Yet it was the remarkably clear vision of Hertz, combined with his consummate persistence and skill, that won for him the prize and justly enshrined his name among the immortal men of science.

Golden accompanies the first major exhibition in the United States of one of the finest private collections of 17th-century Dutch and Flemish paintings in the world, assembled over the past two decades by Rose-Marie and Eijk van Otterloo. In this beautifully illustrated book, works by Rembrandt, Jacob van Ruisdael, Frans Hals, and Jan Brueghel the Elder, among others, represent a wide range of subjects such as land and water, cityscapes and landmarks, still lifes, foreign travels, and burghers, peasants, and painters. In addition, fine examples of furniture and decorative arts shed light on the astounding range of this artistic period. Known as the Golden Age, the 17th century was a time of unparalleled prosperity in the Netherlands, where the emerging merchant class eagerly commissioned and collected paintings, furniture, and other decorative arts. Essays by leading scholars address the context of 17th-century Dutch and Flemish painting, and the history and development of this unparalleled collection. The quality and breadth of the Van Otterloos' holdings illuminate one of the greatest artistic and cultural chapters in European history.


The solutions of cellulose diacetates (CDA) in ionic liquids, 1-butyl-3-methylimidazolium chloride ([BMIM]Cl), 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF4), 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF6) and 1-butyl-3-methylimidazolium formate ([BMIM]COOH), have been investigated to identify the solvent for optimal CDA fiber performance. The CDA/[BMIM]Cl and CDA/[BMIM]BF4 solutions both behave as typical shear-thinning fluids that are beneficial for fiber spinning. The CDA/[BMIM]Cl solution exhibits higher flowability and spinnability than the CDA/[BMIM]BF4 solution. CDA fibers with compact morphology and smooth surface have been fabricated from the [BMIM]Cl solution. The tensile strength of the resulting CDA fibers (3.00 cN per dtex) is significantly improved over that of commercial CDA fibers (1.44 cN per dtex), even when the commercial fibers (3.83 dtex) are thinner than the new CDA fibers (5.20 dtex). The present method to fabricate CDA fibers with improved mechanical properties can be directly used for the production of fabric yarns and garments.

Experimental and numerical methods were performed to investigate the influence of engine-cooling exit flow on aerodynamic performance. The engine-cooling channel was constructed at a simplified notchback model with various outlet layouts. The changes in the main aerodynamic coefficients with different cooling exit flow inclination angles and cooling outlet locations were measured and evaluated, and the reasons and mechanisms were analysed and discussed. The results indicate that reducing the inclination angle is an effective method to improve the cruise performance of a passenger vehicle, and wheels and wheel-housings have significant effects on interference between the underflow and the cooling exit flow.

In order to solve the problem of low recognition rate and high missed rate in current target detection task, this paper proposes an improved YOLOv3 algorithm based on a gated channel attention mechanism (GCAM) and adaptive up-sampling module. Firstly, darknet-53 is used as the backbone network to extract image basic features. Secondly, an adaptive up-sampling module is introduced to expand the low-resolution convolutional feature images, which effectively enhances the fusion efficiency of the convolutional feature images at different scales. Finally, GCAM is added to improve the network's feature expression and detection capability for small targets before the three-scale channels output the prediction results. The results show that the improved method can adapt to multiscale target detection tasks in complex scenes and reduce the missing rate of a small target.


The effects of mixing, ratio of UO/sub 2/: MnO/sub 2/, concentration of H/sub 2/SO/sub 4/, preliminary crushing of oxides, and other factors in UO/sub 2/ and MnO/sub 2/ reactions in sulfuric acid were analyzed in relation to uranium leaching from ores. It is shown that the reaction process takes place at the contact point of UO/sub 2/ and MnO/sub 2/ hydrate surface layers, the rate of the process being limited by steric hindrance. The impontance of iron ions in solid oxidizer (pyrolucite) reaction with the primary uranium minerals in uranium acid leaching from uranium ores is discussed with respect to the above data.

In June 2005, the author interviewed five Sudanese men. All but one had been failed by UK asylum procedures. Their stories are related to other examples of similarly desperate asylum seekers throughout the UK and the effects of policies of forced destitution, detention and deportation are described.


A STUDY OF RELATIONSHIPS BETWEEN FAMILY MEMBERS USING FAMILIAL CORRELATIONS Corinne Wilson Old Dominion University, 2010 Director: Dr. Dayanand Naik Familial correlations measure the resemblance between family members and are used in many fields of study including epidemiology, genetics, heredity, and psychology. Here, an analysis of familial correlations where male and female children of the same family can have different correlations in the unequal family size case is presented. First, three likelihood based tests, namely the likelihood ratio test, Rao score test, and Wald test, and two more asymptotic tests which use Srivastava's estimator of the intraclass correlation coefficient are considered to test the null hypothesis of equality of the intraclass correlation coefficients when families have unequal numbers of children. These methods are implemented on Galton's data set on human stature and a simulation study is conducted to compare the different tests. The simulations show the alternative tests to be better or comparable to the likelihood based tests in certain situations. Additionally, testing the equality of inter class correlations from g independent populations is considered where male and female children of the same family can have different correlations and the family sizes within populations are unequal. For this problem, the likelihood ratio test is compared with two asymptotic alternative tests using Srivastava's estimator of the interclass correlation coefficient that are easier to compute. Simulations are used to study the size and power of these tests. Based on the simulation study, the alternative tests perform well when compared to the likelihood ratio test. Finally, the likelihood ratio test is compared with an asymptotic alternative test of interclass correlation for testing the equality of two parent interclass correlations coefficients, namely, parent-son and parent-daughter interclass correlation coefficients, within families from a single population with unequal family sizes. Both tests are illustrated on Galton's data set on human stature and the results of a simulation study are shown. The results show the alternative test to perform better for certain cases.


We reexamine the locus of narrow-line Seyfert 1 galaxies (NLS1s) on the MBH-σ (black hole mass-bulge velocity dispersion) plane in the light of the results from large new optically selected samples. We find that (1) soft X-ray-selected NLS1s have a lower ratio of BH mass to σ than broad-line Seyfert 1 galaxies; this remains a robust statistical result, contrary to recent claims otherwise; (2) optically selected NLS1s have systematically lower Eddington luminosity ratios than X-ray-selected NLS1s; and (3) as a result, the locus of NLS1s on the MBH-σ plane is affected by selection effects. We argue that there is no single explanation for the origin of the MBH-σ relation; instead tracks of galaxies on the MBH-σ plane differ with redshift, consistent with the downsizing of AGN activity. If these results at face value are incorrect, then the data imply that AGNs with high Eddington accretion reside preferentially in relatively late type galaxies at the present epoch, perhaps a more interesting result and a challenge to theoretical models.


Uromodulin is the most abundant protein ordinary excreted in urine which could be used as a biomarker to diagnose kidney diseases.  However, evidence suggests that it regulates salt transport, protects against urinary tract infection and kidney stones, and has a role in kidney damage and innate immunity. This study aimed to understand the association of uromodulin gene rs13332878 with  chronic kidney disease. More than 100 people were selected for the study and the samples collected from the under study subjects were divided into two groups. 70 chosen subjects were under the dialysis with kidney failure, and  aged between 18-88 years. The second group included 30 samples from healthy individuals, used as control. One of the ways used to identify the genotype was the tetra-primers amplification refractory mutation system–polymerase chain reaction (ARMS–PCR). Regarding the results of SNP (rs13332878), there were three genotypes: GG, CG and CC. Genotype GG was shown in the size 288bp, genotype CG was shown in the size 288+577bp, whereas genotype CC was shown in the size 577bp. The results of frequency genotypes that appeared for GG, GC and CC were 74.29%, 17.14% and 8.57% respectively in patients. Whereas in the control, the frequency of genotypes was GG 3.33%, GC 16.67% and CC 80%. It was observed that less than 1 odds ratio meant that the genotypes were to be considered as a preventive factor. While more than 1 OR meant that the risk had increased (P-value 0.01). No significant differences for the genotypes GC were found when comparing patients and the control groups (P> 0.01). So, we can conclude that there was an association between SNP (rs13332878) of uromodulin with kidney disease and genotype GG should be considered a risk factor while CC genotype represents a preventive factor.


Abstract. This report presents an overview of some of the most recent results obtained by the ATLAS Collaboration using pp and heavy-ion collisions at the LHC. The review is not intended to be comprehensive and includes recent updates on the Higgs boson properties, precision Standard Model measurements, as well as searches for new physics. Most of the results exploit the data collected in the last LHC run, providing pp collisions at a centre of mass energy of 13 TeV.


The current study focuses on the development of duplex Ni-P/Ni-Cu-P coatings by the electroless deposition method. Coatings are developed on mild steel substrates with Ni-Cu-P as the outer layer and Ni-P as the inner layer and vice versa. The coated samples are heat-treated at temperatures ranging between 200 to 800 °C during 1 and 4 h. Coated samples are characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD). The effect of heat treatment temperature and its time duration on the hardness, friction and wear behaviour of both coatings are evaluated and compared. This would help in understanding how heat treatment influences the duplex system of coatings and helps in identifying the suitable condition of heat treatment for optimal performance of the coating. It is observed that heat treatment has a positive influence over the coating performance, which is the best when treated under optimal temperature and time duration conditions. The corrosion behaviour of the coatings is also assessed with the help of electrochemical techniques, viz. potentiodynamic polarization and electrochemical impedance spectroscopy. The results show that the duplex coatings can provide substantial protection to the mild steel substrates. Heat treatment is also found to have a significant influence on the corrosion behaviour of duplex coatings.


Differences in temperature between two oat varieties were found at all levels within the canopy and appeared to be influenced by morphological plant characteristics. In both varieties day temperatures were lower and night temperatures higher than those measured outside the plot over bare ground. For each stage of development, the late-maturing oat was subjected to higher temperatures than the early oat and this became more intensified with late seedings.Generally, tissues were cooler than adjacent air temperature.During a frost, the coldest conditions were found just above the leaf canopy.Over bare ground diurnal variation was greater at ground level than at 150 cm. Measurements at 150 cm were not indicative of temperatures within the plot. A regression analysis showed that both the day and night temperatures adjacent to the panicle could be predicted with a small overestimation by measurements at a comparable height over bare ground. However, it appears impossible to determine generally applicable firm r...

67 learning- and 60 non-disabled children in Grades 1 to 8 participated in a referential communication task in which they provided clues for an experimenter who indicated with varying levels of explicitness the need for a second clue. Facial feedback expressing non-comprehension did not acquire the functional equivalence of explicit requests until Grades 7 to 8. Learning disabled girls in Grades 1 and 2 were less likely than non-disabled girls to respond to facial feedback; however, learning disabled boys in these grades were more likely to respond than non-disabled boys. A locus of control measure administered to children in Grades 3 to 8 indicated that responsiveness to the implicit request, "I don't understand," was related to a belief in internal responsibility for failure.


The purpose of this study is to evaluate the effects of Action-observational training program on gait and balance of patients with hemiplegia. Subjects of this study, among the patients who received the diagnosis cerebral vascular accident, for patients total of 4 people have agreed to research. Experimental group 2 people, control group 2 people, was a total of 4 people. Group-specific arbitration method, was applied to Action-observational training program(experimental group) and general Task-oriented training program(control group). Each training courses 30 minutes for 4 weeks, examined the changes in 10 Meter Walk Test(10MWT), gait speed, Berg Balance Scale(BBS) and time up and go(TUG) ability to examine a total of 4-week course effectively.

After changing the stiffness, the acceleration of the vehicle body and the seat, suspension dynamic deflection and relative dynamic load are compared to select the suitable stiffness to achieve optimal ride performance. It can provide a reference for the one who is designing vehicle suspension.


Analytic philosophy transcends subjective philosophy in a certain extent through emphasizing meaning of proposition and changing Kant's transcendental category in semasiology.However,analytic philosophy negates the presupposition of contradiction between subject and object or the presupposition of contradiction between inner space and out space of person,but reserves the contradiction between form and content.That is to say,it is not complete that analytic philosophy negates subjective philosophy.Analytic philosophy doesn't give up seeking absolute certainty.It still reserves the remains of Kant philosophy.We can only say analytic philosophy transcends subjective philosophy half.


Pangenomics is the study of related genomes collectively, usually from the same species or closely related taxa. Originally, pangenomes were defined for bacterial species. After the concept was extended to eukaryotic genomes, two definitions of pangenome evolved in parallel: the gene-based approach, which defines the pangenome as the union of all genes, and the sequence-based approach, which defines the pangenome as the set of all nonredundant genomic sequences. Estimating the total size of the pangenome for a given species has been subject of study since the very first mention of pangenomes. Traditionally, this is performed by predicting the ratio at which new genes are discovered, referred to as the openness of the species. Here, we abstract each genome as a set of items, which is entirely agnostic of the two approaches (gene-based, sequence-based). Genes are a viable option for items, but also other possibilities are feasible, e.g., genome sequence substrings of fixed length k (k-mers). In the present study, we investigate the use of k-mers to estimate the openness as an alternative to genes, and compare the results. An efficient implementation is also provided.


The liquid-state Raman spectrum was obtained for chloromethyl thiocyanate. The previously unobserved C-S-C bending band was observed at 188 cm−1. The Raman spectrum supports the conclusion that onl...


The Shapley value of fuzzy bi-cooperative game is developed based on the conventional Shapley value of bi-cooperative game. From the viewpoint that the players can participate in the coalitions to a certain extent and there are at least two independent cooperative projects for every player to choose, Shapley value which is introduced by Grabisch is extended to the case of fuzzy bi-cooperative game by Choquet integral. Moveover, the explicit fuzzy Shapley value is given. The explicit fuzzy Shapley function can be used to allocate the profits among players in supply-chain under the competitive and uncertain environment.


Air filtration media are designed for disposable, but in some application, it should be used for some times with water cleaning. Through experiments, the performances of filter, which are cleaned with water for many times, including filtration efficiency, resistance, dust capacity are studied in the paper. The experimental results show that water cleaning has less effect on filtration efficiency, resistance and dust capacity of the filter media. Therefore, air filtration media can be used repeatedly by way of water cleaning.

According to the Malagasy Ministry of Education website, in the school year 2006/2007 there were 3 837 343 students in the public primary schools. The average ratio students/teacher was 52, which means that for every teacher there were 52 students! The average ratio students/classroom was 59 ! in average, every classroom has to accomodate 59 kids. Besides, 59% of the teachers were "FRAM" teachers, which means that they are actually hired and paid by students' parents because of the lack of (...)


(ProQuest: ... denotes non-USASCII text omitted.) TWO SONG CYCLES BAKSA, ROBERT (b. 1938). LETTERS FROM EMILY. Sixteen new songs to poems of Emily Dickinson. Volume One. Composers Library Editions, 2007 (Theodore Presser). Tonal; D^sub 4^-A^sub 5^; Tess: M-mH, CR; regular meters; varied tempos ...; V/M-mD, P/M-D; 38 pages. Soprano. Letters from Emily, Volume One (containing eight of the sixteen new songs on poems of Emily Dickinson) is another entry into the ever growing catalog of musical settings of the poems of one of America's most important poets. Although she apparently craved fame even while protesting publication of her work, Dickinson probably never could have imagined how integral to both poetry and music her poems would become. Even in this single review, there are settings of Dickinson poems by two composers and one setting of a poem about Dickinson's influence on her own poetry by Annie Finch. Five of the eight poems set by Robert Baksa are already familiar in their settings by Aaron Copland: "Nature, the gentlest mother," "Going to Heaven," "Dear March," "Sleep is supposed to be," and "There came a wind like a bugle." That there seems to be no "definitive" setting of any of Dickinson's poems reveals the multiplicity of meanings in her work that allows for a fresh insight or interpretation by each individual reader. Where Copland's settings emphasize the spaciousness of Dickinson's vision, Baksa's reveal her personal intimacy with her subjects. Where Copland's songs project the emotions of the poems outward as onto a large screen, Baksa's look inward to the private stirrings of the heart-drama versus lyricism. Both are contained in the poems; it is left to the reader to experience one or the other, or both, on any given day. Baksas compositional style in these songs is based on choosing one or two musical motifs for the piano part that reflect or represent the main idea of the poem and using them creatively and expressively throughout the song. In "Nature, the gentlest mother," gently moving chords in an eight-measure introduction set the scene of Natures patience with her offspring. Her "admonition mild" that restrains the "rampant squirrel" calls into being a sixteenth-note motif in the right hand that serves intermittently to represent "her assembly" and "the timid pray'r of the minutest cricket." When "all the children sleep," she lights her lamps and "bending from the sky . . . wills silence everywhere" in slower and slower chords that sway back and forth between parallel harmonies, finally coming quietly to rest. "Hope is the thing with feathers that perches in the soul and sings the tune without the words-And never stops at all." Chords with an added sixth or containing a tritone alternate with major chords in a gently undulating pattern of parallel structures, sometimes coming to rest but always moving forward-reflecting the eternal springing of hope in the heart. …


Airtightness of building envelope is a key factor affecting the indoor comfort, air quality, structural durability and energy efficiency, especially for the lightweight prefabricated building systems aiming to achieve the nearly zero energy goals. For panelised systems, the air mainly leaks through the openings and panel joints. However, most current studies concentrate on the airtightness of the former ones, such as windows and doors, studies on joint design are relatively rare. As a result, this study firstly proposes two joint prototypes, the straight joints and the special-shaped joints, with various design parameters. Secondly, the air infiltration volume for different joints are simulated and calculated by the CFD method. Besides, the volume was further compared to find out the optimized joint design. Finally, the airtightness requirements of Passivhaus are used to evaluate the performance of the optimized tongue and groove joint with the conventional straight ones. The results prove that the well-designed joints deliver better airtightness especially for the high-performance standard buildings.

Fig. 1. Left: MRI of a meningionma. Transfer functions (TF) based on boundaries (insets on the left: top, 1D TF with gradient modulation, bottom, 2D TF of intensity vs. gradient magnitude) cannot separate the tumor from the vessels (where gradients are also strong). A transfer function based on occlusion separates the tumor from the vessels and the ventricular structures from skull and skin. Right: CT dataset with contrast agent. Classification is difficult due to overlap between bone and vessel structures (see red color in ribcage in the insets). An occlusion-based TF properly classifies bone and also highlights internal structures (blue). Abstract—Despite the ever-growing improvements on graphics processing units and computational power, classifying 3D volume data remains a challenge. In this paper, we present a new method for classifying volume data based on the ambient occlusion of voxels. This information stems from the observation that most volumes of a certain type, e.g., CT, MRI or flow simulation, contain occlusion patterns that reveal the spatial structure of their materials or features. Furthermore, these patterns appear to emerge consistently for different data sets of the same type. We call this collection of patterns the occlusion spectrum of a dataset. We show that using this occlusion spectrum leads to better two-dimensional transfer functions that can help classify complex data sets in terms of the spatial relationships among features. In general, the ambient occlusion of a voxel can be interpreted as a weighted average of the intensities in a spherical neighborhood around the voxel. Different weighting schemes determine the ability to separate structures of interest in the occlusion spectrum. We present a general methodology for finding such a weighting. We show results of our approach in 3D imaging for different applications, including brain and breast tumor detection and the visualization of turbulent flow.


The mold reconstruction, error analysis theory and application method are studied in this paper, applying the reverse engineering software Imageware with the example of mold reconstruction and error analysis of the engine bearing cover. The figure point-cloud of the part was obtained by the non-contact measurement of the INFINITE 3-D measure equipment. Different processes of reconstructions of the curves and surfaces were carried out after the combination of the point-cloud, reduction of the noise points and the sampling of the key points. The acceptable surface within the assigned error range was compared with the original point-cloud for the error analysis and result evaluation.


Adaptive equalization is a widely used method of mitigating the effects of multipath propagation and Doppler spreading in underwater acoustic communication channels. This paper examines some specifics associated with the design of a multi-channel equalizer for time-varying underwater acoustic channels. More specifically, we study how the number of sensors and separation between them impact the equalization performance of a sparse time-varying channel. We develop a theoretical model and, to illustrate the ideas, find the optimal equalizer for a particular arrival model. Finally, we show how the BER performance depends on sensor separation via processing experimental data.


According to the problem in the study on sterile-type cooling injury in cold region, the basis for temperature and sensitive period of sterile-type cooling injury was put forward.A few easily confused terms was explained.


This work presents the proposal of structures to be used as magnetic bus in high frequency operation. The magnetic bus is used to couple energy systems through the magnetic flux, similar to the capacitive bus widely used in DC microgrids. In systems connected to the distribution grid, galvanic isolation is indispensable and the magnetic coupling brings in addition to this advantage the possibility of interconnecting energy sources with different voltage levels. Its applications range from microgrids to solid-state transformers, with multi-port converters, derived from Dual Active Bridge, as the primary choices for powering systems with high-frequency magnetic coupling. Four pot-core based geometries were proposed and the results obtained by finite element method, showed that they have as advantages compared to core geometries commonly used (shell type, core type and matrix type). These advantages are a lower leakage inductance, higher coupling factor, higher magnetizing inductance and lower core losses.


Measurements of the fall-out fission product activity that accumulates in the air filters employed in ventilation systems are described. A general method for determining the y activity of pelletized filter samples using a NaI well-type crystal spectrometer is discussed. The photofraction of a well-type crystal was measured and data are presented for gamma -ray energies from 0.12 to 1.12 Mev. It is suggested that building air filters be employed in monitoring programs connected with laboratories, reactors, and studies on fall-out. (auth)


In this study we have shown dislocations/defects can be introduced in the form of supramolecularly bound polyacrylic acid and urea based scaffold networks and metal oxide nanoparticles in concrete. By virtue of their supramolecular bonding sites, polyacrylic acid and urea create a network of struts. These struts act as dislocations in an otherwise uniform concrete structure which in turn increase the strength of the concrete. We have also shown that the length of these struts can also be controlled. Such a control over the strut length also led to influencing the strength of the concrete. In short we have shown that effective stress for unit matrix area can be reduced by introducing defects/dislocations in the form of struts which distribute the external applied stress. Consequently the higher the extent of dislocation, the larger is the capacity of the concrete matrix to withstand externally applied stress, the higher is its mechanical strength. We further added ZrO2 and TiO2 nanoparticles to the concrete matrix which enhance the thermal resistivity of the concrete.


The content of Ge in Yibenchang medicinal liquor and Yibenchang Fengshi-Gutong medicinal liquor was determined by phenylfluorone-hexadecyltrimethylammonium bromide spectrophotometry. The results showed that the content of Ge in Yibenchang Fengshi-Ggutong medicinal liquor was higher than that in Yibenchang medicinal liquor. The relation between the therapeutic efficacy and the content of Ge has been discussed.


Background: Emergence delirium (ED) is a distressing side effect of sevoflurane anesthesia in children. Midazolam is a widely studied drug for the prevention of ED with conflicting results. Aim, Settings and Design: We designed this prospective randomized double-blind study to compare the effect of 0.03 mg/kg midazolam administered at induction and the same dose administered 10 min before the end of surgery in the prevention of ED in children undergoing sevoflurane anesthesia and also the effect on the time to recovery in both groups. Materials and Methods: Eighty children between 2 and 8 years belonging to patient physical status American Society of Anesthesiologist Classes 1 and 2 undergoing infra-umbilical surgeries under general anesthesia were randomly allocated to receive 0.03 mg/kg midazolam at induction (Group A) and 10 min before the end of surgery (Group B). Caudal block was administered for analgesia after induction. The primary outcome, the incidence of ED was evaluated using the Paediatric Anaesthesia Emergence Delirium Scale from the time of extubation till 30 min postsurgery. The secondary outcome measured was the time to recovery (time from discontinuation of sevoflurane to the time of extubation) and the results were statistically analyzed. Results: The incidence of ED was comparable between the groups (30%, 10%, 5%, and 2.5% at 5, 10, 15, and 20 min, respectively in Group A and 25%, 10%, 5%, and 2.5% of children at 5, 10, 15, and 20 min, respectively in Group B). Recovery was significantly prolonged in Group B (42.5% of patients in Group A recovered within 6 min of discontinuation of sevoflurane in Group A compared to only 20% of patients in Group B). Conclusion: There is no difference in the reduction of incidence of ED following sevoflurane anesthesia when midazolam is administered at induction or the end of surgery. However, the time to recovery was longer when the drug was administered at the end of the surgery.


Introduction: Pattern of talar articular facets on the superior aspect of calcaneum significantly influence in causation of subtalar arthritis. Enthesophytes from calcaneum is a major cause of heel pain. Evolutionary modification of cuboidal facet on calcaneum is an important aspect of human bipedal gait. The objective of this study was to determine the incidence of calcaneal facet pattern and incidence of enthesophytes in calcaneum.
Methodology: Thirty-four dry human calcaneum were studied in Department of anatomy, Azeezia Institute of Medical Sciences, Kollam. All bones were examined for pattern of talar articular facets and classified accordingly. Meticulous examination was carried out to evaluate the incidence of enthesophytes. Morphometry of articular facet for cuboid and talar facets were carried out.
Results: Pattern I morphologic variant was the most frequently encountered type (25 out of 34). Pattern V not observed. Enthesophytes were observed in 21 (61.7%) bones, with medial predominant medial enthesophytes. One bone showed two enthesophytes. Mean cuboidal facet surface area was 386 (±46) square mm.
Conclusion: It was noted that pattern I was the most common morphological variant. Medial tubercular enthesophytes were most common type of abnormal bony outgrowths of calcaneum. The knowledge about variations in morphology is important for all surgeries in subtalar region.

Key words: Calcaneum, Talar articular facets, Cuboidal facet, Enthesophytes


The purpose of the article is to highlight the structure of the historical process of European integration. Historical phenomenon of the process of European integration is considered as a historiosophical example of unevenness and not the linearity of development. The Great French Revolution set two opposite trends: the development of sovereign national powers while simultaneously spreading universal cosmopolitan ideas. Two world wars weakened Europe's influence on world history. The idea of "Eurocentrism" turned to the background. The process of European integration has recreated Europe's influence on the world-historical process. An interdisciplinary methodological approach to the study of European integration considers it an anonymous socio-historical process. The history of Europe demonstrates the various stages of the development of a liberal rational-market project, which is an integral result of the interaction of different social interests. An alternative is the project of ideocratic, focused on the priority of democratic values, human rights, which are the foundation of European modern civilization. The history of European integration of 1957-1990 was a process of overcoming the ideological split of the continent to the East and West in the Cold War. The Maastricht Treaty actually became a watershed in the transition to a postmodern model of European integration. The experience of developing the European integration process has fixed the following main integration-political strategies: federative community; linear expansion and cooperation of the Union of European Peoples; dual strategy: expansion and deepening of integration; d) flexibility and differentiation of "Europe of Nations"; creation of an integration core of Europe and a strategy of many speeds in the process of European integration, (g) intergovernmental cooperation strategy, sectoral integration, (i) the Directorate of the great powers, Europe of flexible geography, or concentric circles. Therefore, from the point of view of the historical process, the crisis of European integration is structural rather than systemic.


A unique real-time hybrid optical-digital image processing system has been developed to perform analysis of low contrast visual and infrared images in radon-space. This system functions by implementing the forward radon transform (a mathematical tomographic transform of image data from two-dimensional image-space to one-dimensional radon-space) in a front-end optical processor, and a digital processing subsystem operating in radon-space instead of the more traditional image-space. The system works by optically converting the two-dimensional image-space data into a series of one-dimensional projections. All further processing is performed digitally in radon-space on the one-dimensional projections. Applications of interest such as the objective minimum resolvable temperature difference measurement of thermal imagers and automatic pattern recognition are discussed. Also, this paper discusses the topic of real-time object-moment analysis in radon-space which can be used for target identification under conditions of certain image distortions (size, rotation, translation, and contrast). Radon-space object-moments can be calculated using significantly less image data and fewer digital operations than those in image-space.


Cervical cancer (CC) is a public health problem with high mortality rates. The main prevention strategy is the cytopathological examination, known as the Papanicolaou test. Thus, the objective of this work is to evaluate the knowledge of the women of Anápolis-GO about the Pap smear in relation to the purpose of the exam, its relationship with CC and the infection by the human papilloma virus (from the English Human Papiloma Virus, HPV), as well as women's adherence, level of coverage and main factors related to not having the exam. This is a cross-sectional, descriptive and quantitative study, carried out through a semi-structured questionnaire, in the form of an interview. 577 women were interviewed, with a prevalent age range of 34 to 49 years, married, high school, and the number of children under three. 93.6% of women have heard of Pap test and its purposes, but a minority related HPV to CC. Most women perform the exam annually, however they do not know how to inform at least two precautions related to the preparation for the exam, and the main motivation for the exam is medical recommendation / routine exam. As for the reasons for not performing, the most cited were difficulties in performing the exam and not asking the doctor. It is concluded that although the practice of Pap test is comprehensive among women, health professionals must interact more effectively by establishing bonds of trust that override the reasons for non-adherence and that guarantee greater access by the population to information about the CC.


This series of short essays considers the complex choices and decision-making processes of instructors preparing to teach, and continuing to teach, introductory courses in religious studies. In a paper originally presented in the University of Chicago's "The Craft of Teaching in the Academic Study of Religion" series, Russell McCutcheon explores a "baker's dozen" of such choices and the larger pedagogical problems with which they are entwined, ranging from classic questions of skill development and content coverage to philosophical concerns around students' identification with their topics of study and institutional concerns around governance and assessment. Aaron Hollander provides a brief introduction and four doctoral students at the University of Chicago Divinity School respond to McCutcheon's essay, widening its scope, testing its applicability, and interrogating its undergirding suppositions from the perspective of early-career educators in the field.


This paper describes an automated scheme that extracts salient linguistic features from academic text and presents them in an interface designed for L2 students who are learning academic writing. The system is guided by several common ways of utilizing corpus technology in L2 writing. The authors have developed and tested an extraction method that identifies typical lexico-grammatical features of any word or phrase in a corpus. Collocations and lexical bundles are automatically extracted; students can explore them by searching and browsing, and inspect them along with contextual information. They also present learners with common words, and academic words, hyperlinked to their usage and collocates in authentic contexts. This article uses a single running example, the British Academic Written English corpus, but the approach is fully automated and can be applied to any collection of English writing.


A non-adiabatic tapered fiber sensor coated with humidity-sensitive graphene oxide (GO)/Poly (vinyl) alcohol (PVA) nanocomposite film for humidity sensing application was proposed. GO/PVA film was deposited onto the tapered region by dip-coating technique. The surface morphology of the coating film was characterized through Field Emission Scanning Electron Microscope (FESEM). When exposed to percent relative humidity (RH) ranging from 20 to 99.9 % RH, the sensor exhibited sensitivity for both untapered and tapered fibers at −0.00132 ± 0.00043 a. u (%)−1 and 0.00106 ± 0.00008 a. u (%)−1, respectively. The contribution of GO/PVA composite film in enhancing sensor sensitivity was proven, which was 0.00624 ± 0.00033 a. u (%)−1 with percentage of sensitivity boosting up to 15.86 % when compare to the uncoated ones.


A heavy rigid body attached to a relatively light deformable body is a common structure in many mechanical systems. The longterm dynamics of this structure characterize the true features of the structure response to external excitation. Therefore, the study of the longterm dynamics can provide fundamental guidance for engineering design and production. In this thesis, we study a system that describes the longitudinal motion of a light viscoelastic rod carrying a heavy particle. We discretize this problem by replacing the rod with K light particles connected by massless springs. The discretized problem is governed by a system of coupled nonlinear ordinary differential equations. We let 2 denote the ratio of the mass of one of the light particles to the mass of the end particle. This introduces a small parameter into the problem. We use a singular perturbation approach developed by O'Malley and Hoppensteadt to analyze this problem. We focus on the K = 1 case; and the longterm dynamics of this case is reduced to the longterm dynamics of the order 1 outer problem based on the matching condition and the approximate solutions. The longterm dynamics of the order 1 outer problem depends on whether the restoring force f of the springs in the discretized system is monotone or non-monotone. For monotone restoring forces, we show that there exists an invariant manifold M that attracts all solutions to a


We enjoy first-person authority with respect to a certain class of actions: for these actions, we know what we are doing just because we are doing it. This paper first formulates an epistemological principle that captures this authority in terms of trying to act in a way that one has the capacity to act. It then considers a case of effortful action – running a middle distance race – that threatens this principle. And proposes the solution of changing the metaphysics of action: one can keep hold of the idea that we have first-person authority over what we are doing by adopting a disjunctive account of action.

Two new 2D coordination polymers of [M(Enox)2]·C2H5OH (MZn, 1 and Co, 2; HEnox=1,4-dihydro- 1-ethyl-6-fluoro-4-oxo-7-piperazine-1,8-naphtyridine-3-carboxylic acid) were synthesized under hydrothermal conditions. The single crystal X-ray diffraction analyses showed that 1 and 2 are isostructural. The Zn(II) in 1 and Co(II) ions in 2 are six-coordinated in an octahedral environment with an equatorial plane composed of four oxygen atoms:two of them from the 4-oxo and the other two from 3-carboxylate of two coordinated Enox ligands, forming a stable six-membered chelating ring with the apical positions occupied by two N atoms of the piperazinyl rings. Thus, the molecules were self-assembled into a 2D neutral square grid with cavity dimensions of 1.3399 nm×1.3399 nm for 1 and 1.3389 nm×1.3389 nm for 2, respectively. Compound 1 emits strong blue fluorescence on irradiation by UV light in the solid state at room temperature.


The European international academic networking development from a number of isolated research projects into the current powerful unified system is discussed. The repeated interplay between discipline-oriented activities and generic academic computing are considered. The relationship between the European activities and those in other regions – of course including the US, but also other regions of the world is traced. The current initiatives for Europe to remain amongst the world leaders, not only in speed of network but also in helping spread the geographic reach are discussed. Finally, some conclusions and current barriers to full network usage are presented.


An abnormal urine composition is a key reason for kidney stone formation, but little is known about the roles of small metabolites in the urine during kidney stone formation. Here, we found urine glycine in patients with kidney calcium oxalate (CaOx) stone was significantly lower than that in healthy people via 1H NMR spectra detection, and investigated the role and underlying mechanism of glycine in the regulation of CaOx stone formation. Our results showed that glycine could significantly attenuate ethylene glycol‐induced CaOx crystal depositions in rat kidney via decreasing urine oxalate and increasing urine citrate. Mechanism studies revealed that glycine could decrease urine oxalate through downregulating Slc26a6 expression, whereas increase urine citrate via inhibiting Nadc1 expression. Moreover, glycine decreased the protein expression of both Slc26a6 and Nadc1 via increasing the expression of miRNA‐411‐3p, which directly bound to the 3′‐untranslated regions of Slc26a6 and Nadc1 messenger RNAs, in vitro and in vivo. Together, our results revealed a novel role of glycine in the regulation of kidney CaOx crystal formation and provided a potential target for the treatment of kidney CaOx stone.


Application of pesticides creates hazards to the aquatic organisms. This study aimed to determined influence of bromacil, thiabendazole, malathion and mixtures of it on Tilapia nilotica (fish) and D magna . Effects included determination of mortality rate, losing sensation and behavior change (jump attempts) of fish and mortality rate for D. magna using concentration range from 0-6 mg/l. Normal growth of fish and D. Magana was observed under suitable laboratory conditions. The most toxic compound to D. magna was malathion, has an EC 50 (Effective concentration that affect 50% of experimental animal) value of 0.43 (mg/l) compared to that of bromacil 0.59 (mg/l). Mixture of bromacil and malathion was less toxic than separately and have larger EC 50 value 0.64 in toxic unit (TU) indicating potential antagonistic effect. Moreover, thiabendazole was more effective to fish than malathion. Relative toxicity (RT) indicates that thiabendazole has a lower value (0.276) than malathion indicating higher toxicity of thiabendazole. Furthermore, fish and D. magna were sensitive to low concentrations. These data indicate potent threats to aquatic organisms.


Objective To discuss the indication and effects of different reduction mandibuloplasty methods correcting broad mandibular by intra-oral approach.Methods 85 cases were randomly divided into two groups,all unsing intra-oral approach.Group A had 43 patients whose underwent ostectomy of mandible angle by oscillating saw.Group B had 42 patients whose underwent reduction mandibuloplasty by grinding.Results Compared with Group A,Group B had a slighter swelling,shorter recovery period and less bleeding.By 6 months to 1 year follow-up,the cephalometric anteroposterior images showed both the bigonial distance and lower face width were reduced,and both groups had a high satisfaction rate.Discussion Both ostectomy and grinding of mandibular angle could achieving satisfactory effects.However the type 2(Ectropion mandibular angle)had better effects on grinding method,Type 1(Posteroinferior herniation mandibular angle) and type 3(Compound of 1 and 2) achieved better effects with ostectomy.


Let K be a totally disconnected, locally compact and nondiscrete field of positive characteristic and D be its ring of integers. We characterize the Schauder basis property of the Gabor systems in K in terms of A _2 weights on D × D and the Zak transform Zg of the window function g that generates the Gabor system. We show that the Gabor system generated by g is a Schauder basis for L ^2( K ) if and only if | Zg |^2 is an A ^2 weight on D × D . Some examples are given to illustrate this result. Moreover, we construct a Gabor system which is complete and minimal, but fails to be a Schauder basis for L ^2( K ).


Abstract Tick-borne diseases are on the rise globally; however, information is lacking about tick questing behavior. In this laboratory study, we explored tick preferences for stem type (plastic grass, wooden, and metal), questing height, and head orientation. Using 60 Amblyomma americanum adults over three 72-hour replicates, we determined that 21.7% of ticks quested at any given time and that ticks exhibited a strong preference to quest with their heads oriented downwards, irrespective of stem type. Individual ticks tended to quest on only one stem in this study, and a maximum of three. Nonetheless, ticks appeared to prefer questing on wooden and plastic grass stems over metal stems. We did not find an effect of time of day on tick questing rates. Increased understanding of tick questing behavior can improve vector control efforts.


We consider the description logic CFDI∀− nc , a feature-based dialect that allows capturing value restrictions, a variety of identification constraints, and unqualified feature inverses. We introduce PTIME algorithms for various reasoning tasks in this logic, such as knowledge base consistency and logical implication and discuss the necessity of restrictions over CFDInc to maintain tractability. We then show how CFDI∀− nc 's modeling capabilities make it suitable for capturing relational and object-relational data sources (including of n-ary relations) in a natural way.

SUMMARY: Interdialytic weight gain (IDWG) has been reported to contribute to cardiovascular mortality in haemodialysis patients. In order to determine the relationship of IDWG to the pre‐dialysis blood pressure and left ventricular hypertrophy, 168 patients on maintenance haemodialysis were initially evaluated. The IDWG was estimated as the current pre‐dialysis weight minus the preceding post‐dialytic weight and expressed as a proportion (%) of the current dry weight. Patients were divided into two groups: group I consisted of patients with a mean IDWG > 5% each month for 6 months and group II consisted of patients with a mean IDWG < 5% each month for 6 months. As 51 patients had increased IDWG > 5% on more than one occasion, but fewer than six times, they were not included in the above two groups. Thus, 117 patients (33 men, 84 women) were enrolled in this study. All patients received haemodialysis three times a week, with a duration of 4.6 ± 0.5 h per dialysis session. Pre‐dialysis systolic and diastolic blood pressure (SBP, DBP) and left ventricular mass index (LVMI), as determined by echocardiography, were studied regularly. The results demonstrated that the IDWG correlated significantly with age (r = −0.209, P = 0.024) and solute removal index (Kt/V) (r = 0.254, P = 0.006), but did not correlate with pre‐dialysis systolic or diastolic blood pressure. In contrast, LVMI correlated with SBP (r = 0.816, P < 0.001), DBP (r = 0.377, P < 0.001) and age (r = 0.458, P < 0.001). Left ventricular hypertrophy presented in 18 group I subjects (81%) and 68 group II subjects (72%) respectively (P < 0.001). In conclusion, this study shows that excessive IDWG in patients maintained on haemodialysis does not correlate with pre‐dialysis blood pressure, emphasizing that additional factors other than fluid volume may play a role in the control of blood pressure in uraemic patients.

Social media is a new platform for CEOs to build their image and create a strong personal brand to represent themselves and their company. This research examines an outstanding Malaysian fashion icon and social media–savvy businesswoman with over a million followers on Instagram, Vivy Yusof, the youngest Malaysian e-commerce mogul and an example of a successful CEO who has used personal branding to build an empire in the fashion industry. The objectives of this research are to identify the type of messages Vivy Yusof communicates to her audience through her personal Instagram posts and to identify the ways Vivy Yusof's audience engages with her posts on Instagram. Her Instagram post content is classified using the Honeycomb framework that comprises seven functional building blocks, namely, presence, relationships, reputation, groups, identity, conversations, and sharing. In this study, the content of Vivy Yusof's Instagram posts is categorized by how she focuses on the various functional building blocks in her posts and the implications these blocks have on how her audience interacts with the posts. Her social media presence confirms the importance of CEO personal branding because of her role and influence on the masses evidenced by the willingness of her followers to interact (through likes and comments) and engage with her posts on any subject matter, relating either to her business or personal life. The study contributes to a growing body of literature on personal branding strategies by shedding light on the association between content strategies and engagement with social media content.


Texture, magnetic and micromagnetic properties of the martensitic thin films with different thicknesses prepared by magnetron sputtering of Ni52Mn24Ga24 target on paramagnetic Ni-Cr-W cube-textured thin tape are studied. The films exhibit 220-fiber texture. The texture features together with a large magnetocrystalline anisotropy lead to the conclusion about particular domain structure.

257 Background: In December 2016, 49% of patients admitted to inpatient oncology services at UPMC Shadyside had CPR status discussion documentation prior to discharge. This project aims to improve quality and rates of CPR status conversations. Methods: During Plan-Do-Study-Act (PDSA) cycle 1, a stakeholder workgroup was formed in January 2017 by oncology faculty, fellows, nurses and advance practice providers (APPs), medicine house staff, and palliative care faculty. All oncology clinicians were reminded weekly to discuss and document CPR status preferences. APPs received communication training with palliative care specialists. Oncology leadership received a monthly update of CPR status documentation rates, and endorsed CPR status best practice guidelines developed by the workgroup. For PDSA cycle 2, patient charts without CPR status documentation in March 2018 were reviewed. Results: PDSA cycle 1 resulted in CPR status assessment rates increasing from 49% to > 80%. 1400+ more CPR status discussions were documented in 2017 than 2016. The percentage of patients discharged "Comfort Measures Only" or "Do Not Resuscitate" increased from 14.2 (S.D. 2.4) to 20.0 (S.D. 2.1). For PDSA cycle 2, 60 patients without CPR assessment were reviewed. Fifty-two percent were admitted overnight by nocturnists, 48% by daytime APPs, and none by housestaff. 55% (33/60) had metastatic disease. Fifty-three percent (31/60) of patients had prior CPR status documentation in the past 12 months. Fifteen percent (11/60) of patients were admitted for scheduled inpatient chemotherapy. Conclusions: PDSA 1 showed that standardization of CPR status assessment with formal training increased CPR status assessments. More patients wanted CMO or DNR when asked, which may indicate the need for earlier goals of care discussions. PDSA 2 indicated that focusing efforts on completing CPR assessment as part of the admission process, especially for scheduled inpatient chemotherapy admissions, is critical in further improving our rates.


Adenosquamous carcinoma(ASqC) and undifferentiated carcinoma(UC) of the pancreas are rare, and thus we do not clearly know their biological characteristics. We therefore conducted a clinicopathological study of 17 patients with ASqC or UC to investigate their clinical features, imaging findings, histopathological findings of resected specimens, and prognostic factors. The subjects were 9 patients (11.1%) with ASqC and 8 (9.9%) with UC among 81 patients with invasive ductal carcinoma. Mean survival time was 16.3±5.0 months in the patients with ASqC and 12.4±5.6 months in those with UC. Analysis of prognostic factors revealed that survival was shorter in the patients with confluent multinodular type than in those with simple nodular type (5.0±2.4 vs. 18.4±4.8 months, P = 0.039) in patients with stage IVb rather than stage III or IVa cancer (6.2±2.9 vs. 19.4±5.2 months, P = 0.026). Survival tended to be slightly shorter in patients who had recurrence within 6 months. His‐ topathological findings of immunostaining revealed that all 17 patients were positive with CK7 (a marker for adenocarcinoma) in all 17 patients. ASqC and UC were suggested to be differentiated from adenocarcinoma. They are known to have a poorer outcome than common pancreatic cancer, but may be associated with a rela‐ tively good outcome in some patients.


As treatments for rectal cancer improve with developments in surgical techniques, radiotherapy and chemotherapy, the nature of recurrences are evolving. We used a comprehensive database of a large Australian population with stage I–III rectal adenocarcinoma to identify timing and prognostic significance of recurrences, and factors associated with risk of developing recurrent disease.


Background & aim: Esophageal cancer is the eighth common cancer worldwide. In recent years, the improvement in surgical procedures and pre and postoperative care has reduced its incapacity and mortality rates in the intensive care unit. The aim of this study was to investigate the early outcomes of patients with esophageal cancer who were admitted to the intensive care unit of Urmia Imam Khomeini Hospital during 2011-2017. Methods: This retrospective cross-sectional study was performed in the intensive care unit of Imam Urmia Hospital during a 7-year period (2011-2012). , Type of surgery, duration of mechanical ventilation, length of stay in intensive care unit, mortality were extracted. The data were analyzed using independent t-test and chi-square test Results: The mean length of admission in the ICU among patients with SCC esophageal cancer was 8.46 ± 5.86 days and among adenocarcinoma patients was 6.74 ± 3. 59 days (P = 0.001). The mean length of hospitalization among patients with SCC esophageal cancer was 13.19 ± 6.4 and was 12.02 ± 6. 02 days, respectively (P = 0.04). Mean duration of mechanical ventilation among patients with SCC esophageal cancer was 5.58 ± 5.31 days and 4.69 ± 2.91 days among patients with adenocarcinoma. (P=0.001). Of 481 patients with esophageal cancer, 375 (78) discharged and 106 (22%) died. Conclusion: The results of the present study confirm the limited results of limited studies on the outcome and characteristics of patients with operated esophageal cancer admitted in ICU.


Long Term Evaluation (LTE) has been used to achieve peak data rates in wireless communication system. Turbo codes are utilized as the channel encoding scheme. MAP algorithm has been used as a decoding scheme. Complexity in MAP algorithm is minimized by implementing the algorithm in log domain giving rise to Log MAP algorithm. The main purpose is for reducing the difficulty of state metric computation by employing of numerous algorithms and these algorithms differ only by their implementation of correction terms. By utilizing constant log MAP algorithm, linear log MAP algorithm, MAX log MAP algorithm, multi step log MAP algorithm and hybrid log MAP algorithm ACS unit is implemented.  The state metric calculation is implemented with the help of radix-4 Add -Compare-Select (ACS) unit. The distance calculation is involved between two concurrent computations of state metric can be shared among them which give rise to Maximum Shared Resource (MSR) architecture. The proposed implementation of these algorithms leads to reduction in the power dissipation, propagation delay and the number of logical elements used for the recursion computation in turbo decoders used in LTE system.

Techniques for non-stationary signal analysis are important in understanding dynamical behaviour of complex systems. Time-frequency coherence is widely used to analyse time-varying characteristics in non-stationary signals. This paper presents wavelet-based methods, using Airy wavelet, to estimate coherence. We incorporate a novel technique for removal of low frequency components due to envelope modulation in non-stationary signals. The technique is demonstrated on synthetic and real neurophysiological data. Results not only provide a clear description of desired features in non-stationary signals, but also suppress low frequency components due to envelope modulation. Our novel technique shows an effectiveness in extracting features hidden within the signals. It may lead to improved results in coherence analysis of medical, biological, physical and geophysical data containing low frequency envelope modulation besides non-stationarities.


A possibility of fuelling a solid oxide fuel cell stack (SOFC) with biomass fuels can be realized by coupling a SOFC system with a self-standing gasification unit. Such a solution enables multi-fuel operation, elasticity of the system as well as the increase of the efficiency of small-scale biomass-to-electricity conversion units. A system of this type, consisting of biomass gasification unit, gas purification unit, SOFC stack, anode off-gas afterburner and peripherals was constructed and operated successfully. During the process, biomass fuel (wood chips) was gasified with air as gasification agent. The gasifier was capable of converting up to 30 kW of fuel to syngas with efficiencies up to 75%. Syngas leaving the gasification unit is delivered to a medium temperature adsorber for sulphur compounds removal. Steam is added to the purified fuel to maintain steam to carbon ratio higher than 2. The syngas then is passed to a SOFC stack through a fuel preheater. In such a configuration it was possible to operate a commercial 1.3 kW stack within its working regime. Conducted tests confirmed successful operation of a SOFC stack fuelled by biomass-sourced syngas.


or factory workers, or government employees, or even professors." Not all the propositions set forth in this little book are new, but many of them are more cogently expressed here than they have been elsewhere. As a militant defense of the democratic processes of government, written in a lively, entertaining style, with more than occasional flashes of humor, these chapters were well worth writing, and being so, they are equally well worth reading.

Sustainable teaching model innovation is an important way to build a new business discipline in Chinese university business school; however, its effective implementation faces various challenges. This paper conducts an exploratory study on the current status of teaching practices in the business school of L University using personal interviews and questionnaire surveys. This paper compares the main performance of three stages in the initiation of teaching activities, use of teaching methods, and evaluation of teaching effectiveness in the business school of L University. We used project-based learning (PBL) theory, modular teaching theory, and deliberate practice theory to analyze three problems in business school teaching practice: lack of linkage between business knowledge modules, lack of articulation between business theory and business practice, and lack of systematic thinking in course assessment and evaluation. Based on the analysis of the above problems, this paper proposes three countermeasures: to reconstruct the relationship of "course-knowledge-tool" with modular thinking, to strengthen the linkage between theory and practice with deliberate practice, and to promote systemic thinking with real problems assessment. This research is essential to cultivate new business talents with "business theory + business skills + system logic", and to build a new business talent education system for the digital economy and new consumer development requirements.


The cause of bitterness generated by the buckwheat shochu and its solution were investigated. The bitterness of the buckwheat shochu was not generated by phenolic compound,etc., but by excessive isoamyl alcohol and little n-propyl alcohol. This might have been caused by the water-soluble protein in the buckwheat seed. There was an isoelectric point near 8 on this water-soluble protein, which affected the flavor component generation and amino acid metabolism of the yeast. This water-soluble protein was decomposed by the protease, and its influence to the yeast was abolished. It seemed possible that the isoamyl alcohol quantity could decrease and that there -would be little bitterness when the added enzyme was deactivated with heat after the acid protease was made to work with the raw material buckwheat.


Travel time reliability impacts traveler decision making especially under congested traffic conditions. Several factors are identified as causes of unreliability in transportation networks. Among those, crashes (and near-crashes) and heterogeneity across drivers are two factors directly related to the behavior of drivers, but which are not typically captured in existing microscopic simulation tools. This paper presents an effort that relies on a cognitive risk-based microscopic model that is capable of considering crash occurrence endogenously, to investigate the importance of considering the drivers' heterogeneity and incidents in microscopic simulation models to study the travel time reliability. Two highway segments in Chicago, IL and New York, NY are simulated using the actually observed traffic data as well as output from a mesoscopic simulation model as the input to the model. The simulation results are then validated against the actual observations. Different heterogeneity consideration methods are compared and the results show the importance of considering correlation among model parameters to reduce the bias in estimating the travel time and travel time reliability. Finally, the safety related feature of the model are investigated and validated against the actual crash data.


This investigation considers a generalized inspection policy for a deteriorating production system with general random minimal repair costs. The inspection times for the inspection strategy are assumed to be non-negligible. Additionally, uncertainty probabilities associated with inspections are introduced. Using a dynamic programming formulation, the optimal inspection time for maximizing profit per unit time for a given overhaul/replacement time is determined. Next, the procedure is extended to determine the optimal periodic overhaul/replacement time, as well as the optimal number of inspections and their schedule.


Instrumental analysis has disposed classical chemical analysis in every analytical laboratory, since many decades, as it is faster and more productive. Beyond any doubt chromatography and above all High Performance Liquid Chromatography (HPLC) is the workhorse in routine analysis, either as standalone technique or hyphenated with specific and more sensitive spectroscopic techniques. Thus the detection of analytes can be feasible at low concentrations following regulatory requirements, as for example those set by environmental protection agencies, food authorities or pharmacopeias, that are getting stricter every day.


AbstractThe Pliocene to recent Taixinan basin is a unique foreland basin built on the northeastern part of the northern passive margin of the South China Sea (SCS). We have used multichannel seismic profiles tied to well controls from ODP Leg 184 to investigate the tectonic and sedimentary characteristics of the foreland basin. We defined three seismic sequences, dated respectively to the Pliocene (5.33–2.5 Ma), early Quaternary (2.5–1.0 Ma), and late Quaternary (1.0 Ma–present). They represent three stages of evolution of the foreland basin. We have recognized seven types of seismic facies, which are parallel-to-subparallel, progradational, fill-type, divergent mounded, wavy, lenticular, and chaotic facies, and are interpreted as hemipelagic deposits, deltas, submarine canyon fills, levees, sediment waves, submarine fans, and mass transport deposits, respectively. Seismic facies analysis indicates that sedimentation within the foreland basin has been dominated by turbidity currents and the other gravity ...


We consider a system composed of an elastic tube, which is fixed at the outer boundary and in frictional contact with a rigid cylinder, rotating inside the tube about the common axis. Under the assumption of Coulomb's friction law at the contact surface between the two bodies several types of rotating slip‐stick and also slip‐stick‐separation travelling waves with different wave numbers can be observed.


The effect of intake of resistant starch on the digestive response of the rabbit was analysed by comparing a low, medium, or a high intake of resistant starch obtained by replacing wheat starch (WS) by raw potato starch (PS) in diets. Three diets, with 0, 7 or 14% of PS (resp. WS, PS7 and PS14) and having a high and similar concentration of starch (20%), were given to adult rabbits. The ileal, caecal and total digestibility, and the bacterial enzymatic activity (cellulase, xylanase and pectinase) have been measured in ileo-cannulated animals. In adult rabbit the ileal digestibility of starch was over 95%, while that of protein averaged 69%. Only the ileal starch digestibility was slightly reduced (98.3 for 96.7%; P=0.001) when 14% of potato starch replaced wheat starch. The bacterial fibrolytic activity in the caecal content was not significantly affected by level of resistant starch. Consequently, we assume that even for a high intake of resistant starch, the ileal starch concentrations and flow remained low, and should not be a risk factor for the microbial activity and balance in the caecum.
