A new definition of image information quantum is proposed. Five improved entropy information based on scientific segmentation methods for remote sensing images is brought forward. These algorithms are simulated with MATLAB, and some optimizations of algorithms' performances are made. The best thresholds and consumed time of different algorithms are compared and analyzed. These experiment data show that these new algorithms make qualitative improvements in precision and speed compared with other algorithms.


Abstract Dyad reading involves a lower level reader paired with a higher level reading partner who models proficient oral reading while providing access to challenging texts. Previous research has reported increased reading fluency and comprehension for participants of dyad reading; however, to date no research has investigated how dyad reading may influence student attitudes toward reading. Using mixed effects linear modeling, this quasi-experimental study of third graders investigated the academic and attitudinal outcomes for students who read in dyads for 15 minutes daily for 90 school days. Results indicated that dyad readers experienced mixed outcomes in improving reading proficiency and a pattern of decline in reading attitudes compared to students in the control group. While lower level dyad readers demonstrated significant gains on a measure of comprehension, there were no differences between groups on several other measures of reading. Recommendations target how to maximize the use of dyad reading to support students' reading development without eroding their perceptions of themselves as readers.


This article discusses the importance of the legal inquisition in the medieval Crown of Aragon. The form is reviewed from its Roman origins through the influence of Visigothic law and that of the various law codes of eastern Spain during the Middle Ages. The use of the legal inquisition by the crown, the church, the nobility and town governments clearly demonstrates how adaptable it could be. The form's manipulation of both written evidence and witness testimony is crucial for the understanding of how Iberian law perceived and shaped the memory of past events.


The development of a sustainable energy portfolio to mitigate climate change is one of the great challenges we are facing today. The United States has set goals to develop a bio-based industry for fuel, power, and other products. At the same time, we are seeing an increasing investment in renewable energies, like wind and solar. The development of new technologies leading to a clean energy economy will be critical to long-term economic competitiveness and the ability to win the betting tips future. This investment has to be coupled with next generation manufacturing technologies such as ad-ditive manufacturing.


This paper examines the multiple and heterogeneous, current and potential, relations between hybrid actors of tourism in Favela Santa Marta, Rio de Janeiro. It seeks to elucidate the legitimizing potential of tourists acting as "connectors" that reach beyond formal politics' hindrances. This work applies assemblage theory epistemological framework, and Actor-Network Theory ethnomethodological tools, to explore the issues and roles questioned, altered, made visible, or transformed through favela tourists' practices and performances. Hence, avoiding the ethical dilemmas and representational concerns from slum tourism researchers in the past. Our fieldwork engages with two favela tours. We follow tourists as they stitch hybrid actor-networks that create multiple orderings in such assemblages, and their material and semiotic configurations. Our research reveals that such tours could be related to different shifts in the favela's political, social, economic, cultural, and material dimensions.


The double PWM converter is the important part of energy conversion in the direct drive wind power system.The principle of direct drive wind power system is analyzed.In order to achieve the maximum wind power capture and improve the quality of the output power of the system,the method using the direct torque control(DTC) in the machine side and the direct power control(DPC) in the nets side converter is proposed.The simulation using the MATLAB/Simulink shows that the control scheme can effectively capture the maximum wind with stable DC bus voltage and good dynamic response.


Vascular implants to replace the native heart valve has a self-expanding stent for supporting a valve body having a valve leaflet. The stent is preferably provided with a configuration anchor structure to prevent the implant to pass through the annulus. For arranged, the implant is compressed in the installed device is fixed to one end thereof. During the arrangement, the implant is partially released from the disposed device, positioning of the implant is confirmed before it is completely released. The implant may, if desired, may be at least partially re-housed and repositioning.


The doctrine of uti possidetis iuris provides that, in the succession of States arising from secession or disintegration, territorial title is delimited between successors according to internal borders at the time of succession. Although it is commonly accepted that the concept originated in the nineteenth-century successions in the Spanish Americas and was generally adopted by the twentieth-century decolonization successors in Africa, international law scholars have been divided on whether the doctrine has thereafter evolved into a universal rule of customary international law that presumptively binds successors but is rebuttable by common agreement. This article argues that the 'presumption' of binding application is not supported by precedent and is inconsistent with the principle of consent. Rather, the law of State succession is neutral on the delimitation of successors' frontiers: uti possidetis iuris is one of several methods of territorial delimitation that may be adopted by their common consent.


The biological characteristics of two kinds of TC-resistant strains, one of which was obtained by transduction with phage 81, using as a donor strain the tetracyclin-resistant S. aureus H-37, and as recipient the tetracyclin-sensitive S. aureus H-56 and H-64, and the other by the step-by-step method, were compared.Betweela the original strains and transductants, there were no differences in the production of coagulase and alphalysin, the contents of beta-carotin, phosphatase activity, toxicity to mice and the growth curve. The tetracyclinresistant strains of H-56 and H-64 obtained by the step-by-step method, however, showed the marked decrease in the production of coagulase, and alpha-lysin and in the toxicity to mice, and no trace of bata-carotin and phosphatase and more delayed growth curve.


A nonwoven aperturing process is.called Stretch Apertured Nonwoven (SAN) technology.One or more layers of nonwoven are processed through a specially patterned, secondary point bonding heated calendar, and then incrementally stretched via ring rolls.The resultant apertured nonwoven retains the original bond points but displays apertures at every secondary bond point.This approach eliminates past barriers toward obtaining nonwovens of high aperture clarity combined with sufficient strength and high softness.


Amongst the therapies available to stroke sufferers, one that is gaining attention is the application of video games to encourage therapeutic movement. The Limbs Alive project at Newcastle University has developed a system that gathers therapeutic game data from patients, uses statistical tools to estimate a number of performance metrics and presents the results to patients and clinicians via web applications. This paper describes the architecture of this system and outlines the various technical challenges that were overcome, including in security and deployment.


Genetic studies were conducted to gain an understanding of the inheritance of adult plant resistance (APR) to leaf rust in six common wheat varieties. The Australian varieties 'Cranbrook' and 'Harrier' each carry two genes for APR to leaf rust. These genes are genetically independent of the seedling resistance genes Lr23 and Lrl7b, carried by the respective varieties. Adult plant resistance in 'Suneca' was conferred by at least two genes, in addition to the seedling genes Lr1 and Lrli. It is likely that the APRs in 'Cranbrook', 'Harrier' and 'Suneca' are conferred by uncharacterized gene(s). Tests of allelism confirmed that seedling resistances in the varieties 'Avocet R', 'Hereward', 'Moulin' and 'Pastiche' are conferred by Lrli. Adult plant resistance in the variety 'Hereward' was inherited monogenically, whereas varieties 'Moulin' and 'Pastiche' each carried two dominant genes. On the basis of rust specificity and pedigree analysis, it would seem likely that the APR genes in 'Hereward', 'Moulin' and 'Pastiche' are also currently uncharacterized.


Last week, the U.S. government took two important steps on the long road to testing the feasibility of burying carbon dioxide to combat global warming. The Department of Energy chose three sites in Texas, North Dakota, and Alberta, Canada, to inject 1 million or more tons of CO2 from coal plants in


The WWW, with its hypermedia capability, has afforded a new medium for delivering text, images, and graphics. It becomes an ideal platform for disseminating CME materials. One advantage of CME information on a WWW server, is its potential for user access on their own time (asynchronous mode). The worldwide distribution of the Internet permits an efficient method of information dispersion, one "instructor" (server) for a multitude of potential students. The Uniformed Services University of the Health Sciences (USUHS) Department of Pathology has undertaken a project to provide CME through the World Wide Web. The primary goal of the project is to provide CME to uniformed services physicians especially those in remote sites in the continental United States and overseas. A secondary goal is to serve physicians and allied medical practitioners in the civilian sector. It is also intended to be a training tool for pathologists and other diagnosticians.


There is a wide variety of reasons for the notorious growth in distance education (DE) (Allen & Seaman, 2004) and these have been well discussed (Moore & Anderson, 2003). Universities can increase enrollments without increasing their physical plant requirements. They can reach out to audiences that would not otherwise be able to attend post-secondary education as well as to new audiences who would normally not attend that particular institution. For many, the online environment provides their only avenue to post-secondary education or professional development opportunities. Most DE learners are time restricted by work requirements or similar restrictions; those that cannot afford the residential or commuting costs, and those who are house bound with children, with a disability, or other constraints. A very large number of those taking online courses are "part-time" learners and young adults or adults (Tucker, 2003). Learners who are at a distance need ease of access, affordability, and greater flexibility in their learning environment.


The initiation of a de tonation in Pulse Detonation Engines (PDE) has been identified as one of the critical and enabling technologies for PDEs. In particular, the initiation of practical fuel -air mixtures containing liquid droplets without supplementary oxygen or other high lo ss mechanisms is a capability that could enable the PDE to exceed the performance of ramjets and expendable turbo -machinery based systems. Although many past engine concepts have relied upon sensitive fuel/oxygen initiator unit s or unrealistic gaseous fu els such as hydrogen and ethylene , the split -path PD E has been designed to enable the use of JP -10, a high -density liquid fuel. Flow through segments of th e combust or was both modeled with a compressible flow solver and experimentally evaluated in the lab oratory at simulated flight conditions . A s piral -lined initiator demonstrated a significantly lower total pressure loss when compared to a ring -lined version , and thus was the preferred initiator configuration. Experimental values for the turbulence were found to be significantly lower than the computed values at similar conditions when using a k -�model. Finally, successful ignition s of the JP -10/Air initiator were achieved up to refresh Mach numbers of 0. 13 at inlet pressures and temperatures of 150kPa and 550 K, respectively. The increase head -end recirculation/rotational regions with 60 -degr ee versus the 45 -degree side dump angles of the inlet arm s substantially improved the ignition success rate.


Hong Kong is one of the wealthiest cities in Asia, a center of world trade, a place of many comings and goings. It is an international hub, whose social and cultural landscape is heterogeneous, hybrid, and transnational. Included in Hong Kong's population of 6.4 million are over 130,000 Filipino domestic workers, representing the territory's largest non-Chinese minority. In the 1970s there were but a few hundred Filipinas who worked as "domestic helpers" for expatriate employers in the colonial city.1 Their popularity quickly grew among the burgeoning middle-class Chinese population, which found it increasingly difficult to attract local Chinese women to do paid household work. By the 1990s well over 10 percent of Hong Kong's population employed domestic workers of some sort. Women of numerous other nationalities are included among the foreign domestic workers (among them Thai, Indonesian, Sri Lankan, Indian, and Malaysian), but by far the largest group is women from the Philippines. The majority of Filipinas are between the ages of 20 and 40, most are Roman Catholic, and approximately a quarter are married. Contrary to many locals' expectations, Filipina domestic workers do not come from the poorest or least educated sector of the Philippine population. The vast majority have attained more than a high school education, and some belong to middle-class families. They come to Hong Kong on two-year contracts, holding temporary work permits that are administered by the Philippine Overseas Employment Association and the Hong Kong labor and immigration departments. By far the largest group of employers today are local Chinese, many of whom have recently joined the ranks of Hong Kong's


This paper presents data from the Bern dialect of Swiss German from a typological perspective. Bern Swiss German is impressionistically more OalpineO than Northern Standard German, partly as a result of their distinct Odefault accentsO, H*+L in NSG and L*+H BSG. Similar dialectal variation has also been reported for English. Like Northern Standard German, Bern Swiss German can associate L phrase tones to the end of focus or to a postnuclear stressed syllable. Assuming a typological framework which recognizes distinctions between phonetic and phonological aspects of intonation as well as universal and language-specific aspects, the differences between BSG and NSG discussed here are taken to be phonological rather than phonetic. 1. TYPOLOGY OF INTONATION Work on intonation is slowly gaining ground in typology (see for instance [13]). Ladd [14] shows that BolingerOs [2, 3, 4] OuniversalistO theory of intonation is steadily losing ground to OphonologicalO theories of intonation (beginning with Bruce [5] and Pierrehumbert [17]). The former contends that intonation is extralinguistic, essentially emotional. The closest it comes to the grammar is the phonetics, meaning that any typological generalizations to be made about it are not like those made for the grammar. In the latter, intonation has a decidedly phonological component distinct from the phonetic implementation, and thereby cross-linguistic differences can be either phonetic or phonological. A sketch for a typology of intonation is given in Table 1. This is slightly modified from Ladd [14], who adapts WellsO [20] taxonomy of segmental variation to intonational variation, and incorporates GussenhovenOs [10] distinction between the phonetic and phonological levels of intonation. The first cut is between the extralinguistic N which includes some of the aspects of intonation that Bolinger considered truly universal, including communicative functions like the imparting of emotion or interest N and the linguistic. Under linguistic, the next cut is between the universal and the language-specific. BolingerOs universals are vague tendencies that all have counterexamples, but they can be salvaged with OweakO versions. Under language-specific, the next cut is between the phonetic and the phonological. The traditional distinction is that gradient differences are phonetic and categorical differences are phonological. As for phonetics, we can separate the universal aspects like intrinsic pitch of segments from the languagespecific, phonetic-y, non-meaningful aspects, such as late vs. early peak alignment, interpolation vs. spreading of static tones, possibly compression vs. truncation, and perhaps various downtrends and uptrends, such as downstep/catathesis, upstep, downdrift, and final lowering. Phonological aspects of intonation can be categorized according to the phonological form of tunes, the inventory of phonological tunes, and the meanings assigned to phonological tunes. Phonological form differences include phonotactics, tonal shapes, (e.g. monotonal vs. bitonal pitch accents or phrasal tones), well-formedness conditions on tunes (e.g. OCP effects), distribution of tunes, tune-text association, phonological rules (e.g. deletion, Tone Linking, possibly truncation), phonological phrasing, deaccenting, and so forth. Systemic differences refer to the intonational distinctions languages make, that is, what set of tunes each language has in its inventory. For instance, Glasgow English neutralizes the distinction between statements and questions ([14, 16]), which other dialects maintain with distinct contours. English and German neutralize neutral focus with narrow focus on the rightmost element, while Bengali distinguishes them with two different contours. Semantic differences refer to the meaning and use of tunes. As soon as we adopt the phonological/typological view of intonation, we practically take it for granted that languages and dialects use different tunes for the same meaning or have different meanings for the same tune. There are still numerous aspects of intonation that are not included in this table, such as discourse factors and disfluencies. page 941 ICPhS99 San Francisco


This article is an analysis of the system and content of international migration regulations, in terms of the evolutionary element and the significance of international standards in this regard. Illegal migration is one of the international criminal phenomena that has characterized societies of all times. At the current stage, however, this phenomenon has taken on a very large scale. Migration processes are taking place simultaneously and are growing in many countries around the world. However, effective management and proper regulation of migration can play an important role in the development of societies and the reduction of human poverty. In this repsect, the regulation of the migration phenomenon imposes on the situation the adoption and implementation of related international and national standards. In fact, international standards have formed and continue to form the basis for the prevention and detection of the crime of organizing illegal migration, provided by art. 3621CP the RM, the character of which concerns transnational elements of this phenomenon.


Aim: To investigate the relationship between hypermetropia and systemic hypertension. Methods: The study was performed on 2 groups of participants (a total of 1,162 participants). Group 1 comprised 370 patients with arterial hypertension and 205 age- and sex-matched normotensive subjects. Hypertension was defined as systolic blood pressure ≧140 mm Hg and/or diastolic blood pressure ≧90 mm Hg. Spherical equivalents between –0.50 and +0.50 dpt were regarded as emmetropia. Keratometry, anterior chamber depth (ACD) and axial length (AL) were measured with IOL Master (Zeiss, USA). Group 2 comprised 124 myopic, 206 emmetropic and 257 hypermetropic subjects. Differences for mean spherical equivalent, keratometry, ACD and AL measurements between hypertensive patients and control subjects (group 1) were compared using independent-sample t test and Mann-Whitney U test, and distributions of refractions were compared with the χ2 test. Distributions of hypertensive and normotensive subjects (group 2) among myopic, emmetropic and hypermetropic subjects were compared with the χ2 test. Results: Mean spherical equivalents of the patients with hypertension and of control subjects were –0.03 ± 1.63 and 0.22 ± 1.82 dpt, respectively (p = 0.182). The differences for keratometric values, ACD and AL were not significant (p = 0.151, 0.692 and 0.548, respectively). There was also no significant difference (p = 0.143) for hypertension ratios among myopic (66.1%), emmetropic (57.8%) and hypermetropic (55.6%) subjects. Conclusion: There is no association between systemic arterial hypertension and hypermetropia.


Objective To compare the effects of using different ways to block "gut-lymph " pathway on endotoxin,cytokine,and lung function.Methods Fifty special pathogen free (SPF) leveled SD mice were randomly divided into 5 groups:control group (blank) ; sham group (sham) ; ischemia/reperfusion group (I/R) ; ischemia/reperfusion plus lymph duct ligation group (I/R + L) ; and ischemia/reperfusion plus lymph drainage group(I/R+D) (n=10).Results I/R,I/R+L and I/R + D groups had significantly higher levels of endotoxin and cytokine in serum than in blank group and sham group [endotoxin in I/R vs.I/R + L vs.I/R + D vs.blank vs.sham:(0.039 4 ±0.002 5) vs.(0.029 9 ±0.003 9) vs.(0.028 9 ±0.003 1) vs.(0.025 2 ±0.004 2) vs.(0.026 2 ±0.001 3) Eu/ml; tumor necrosis factor-α(TNF-α):(49.92±7.48) vs.(36.85 ± 13.46) vs.(27.67 ± 10.12) vs.(18.86 ± 12.70) vs.(25.80±11.19) ng/L; interleukin (IL)-6:(41.78±9.75) vs.(19.14±1.48) vs.(19.20±4.14)vs.(8.69 ± 0.76) vs.(11.57 ± 2.90) ng/L;P < 0.05 respectively).After blocking lymph duct,I/R +L and I/R + D groups had remarkably lower levels of endotoxin and cytokine in serum,and nitric oxide (NO) and inducible nitric oxide synthase (iNOS) in the lung than in I/R group (P <0.05),The concentrations of NO,total nitric oxide synthase (tNOS),and iNOS in I/R + L and I/R + D groups were extraordinarily higher than in sham group (P < 0.05).Conclusion By blocking " gut-lymph" pathway,both lymph duct ligation and lymph drainage could reduce the local intestinal tract inflammation and distant organ injury incurred by intestinal ischemia/reperfusion,and the effect of lymph drainage was superior to lymph duct ligation,but with no significant difference.

A nonlinear detection scheme for coherent PAM (pulse amplitude modulation) and QAM (quadrature amplitude modulation) is developed. The detector is based on a median-type digital filter, called a matched median filter, which is the natural counterpart of the linear matched filter in the class of median-type filters. These filters are optimal for Laplace noise, and it is shown that they lead to a robust detection scheme which also performs well when strong impulsive noise corrupts the signal. Formulas for detection error probabilities are derived, and simulation results confirming the expected behavior of the detector are presented.<<ETX>>


In this paper, the iron loss of an actual stator core of the complex configuration was evaluated by using the proposed effective magnetic path length and the excitation inner core, which were developed in this research. The iron loss of an actual stator core in the manufacturing process was described. Iron losses of actual stator cores before and after the varnish processing were measured using the excitation inner core of several kinds of shapes. As a result, iron losses of actual stator cores evaluated using the proposed effective magnetic path length were within appropriate values.


The evaluation of Hydronephrosis using Tc-DTPA renal Scintigraphy & CTUrography has been carried out among 60 hydronephrotic patients with age groups between 20-80 year, 27 patient assessed by CT urography ,27 assessed by dynamic renal Scintigraphy and 6 patient assessed by both . The parameters discussed are the age, weight and degree of the Hydronephrosis (mildmoderate severe). The results from dynamic renal Scintigraphy using Tc-DTPA radiopharmaceutical reveal that: the predominant occurrences of hydronephrosis were among the age group of 20-30 years old, While the least occurrence for the age group of 30-40 years old. The result also found that the relationship between the age and occurrence of hydronephrosis is an inverse relationship demonstrated by the following equation (y = -0.571x + 18.66). The results also reveal that the predominant occurrence of hydronephrosis were among the weight group of 50-60 kg, While the least occurrence for the weight group of 90-100 kg with inverse relation demonstrated by equation (y = -3.192x + 27) . Also the result reveals the degree of hydronephrosis (mild 50% -moderate 16.67%Severe 33.33%). The results from CT urography reveal that the predominant occurrence of hydronephrosis were among the age group of 40-50 years old, While the least occurrence for the age group of 70-80 years old which has reversible relation and could be demonstrated by the following equation (y= 3.964x + 30.12 ). The results also reveal that the predominant occurrence were among the weight group of 50-60 kg, While the least occurrence for the weight group of 80-90 kg which has also reverse relationship demonstrated by the equation y=1.585x +22.20 . Also the result reveals the degree of hydronephrosis (mild 50% -moderate 16.67%Severe 33.33%). The accuracy, resolution and cost and of these methods has been compared.

The objective of this research was to analyze the personality traits of successful Indonesian start-up entrepreneurs whose businesses were in the top 200 based on start-upranking.com. Using IBM Watson Personality Insights, the Big Five personality traits from 27 samples were measured. The Big Five personality traits include openness, conscientiousness, extraversion, agreeableness, and neuroticism. The data were analyzed using descriptive statistics and mean comparison. Mann-Whitney U test was used to determine the difference in personalities between genders, while the Spearman test was utilized to identify the correlation between education level and personalities. The results revealed that Indonesian start-up entrepreneurs tended to be more open, more conscientious, moderate in extraversion, less agreeable, and more neurotic (O+, C+, E, A-, N+). There was no personality difference in different genders and no correlation between education level and personality traits either. The results of this study should serve as a point of departure for future studies on start-up entrepreneurs' personality traits in Indonesia. Additionally, future studies are suggested to employ a larger number of samples from different countries.

Replica control protocols are used to insure consistency among different copies of a data item in a replication system. The availability of a replicated item is an estimate of the suitability of a certain protocol. In this paper, we present an object-oriented model for evaluating the availability provided by a replica control protocol. The model is expressed in terms of its static structure and dynamic aspects.


This work is based on an unpublished source written by Jean d'Outremeuse, a medieval chronicler of Liege (end of XIV th c.): the fourth book of the Tresorier de Philosophie Naturelle des pierres precieuses. The book consists in a collection of recipes devoted to the imitation of gems by different ways of glass coloring. The richness of this kind of literature necessitates an interdisciplinary approach and shows the complementarities between texts and analyses for a better knowledge of the ancient glass techniques and for a good enterpretation of the works of art. The Tresorier allows us to open ii new field in ancient glass studies.


Abstract A 5 year study of the foliage inhabiting fauna of young apple trees which had never been treated with insecticides or miticides showed there were large numbers of species varying considerably in quantity. The study also showed that the manner in which the foliage is distributed by cluster type and the distribution of the many species on the clusters are important factors in the sampling of mixed populations of arthropods.The leaf clusters were classified into six types based on stem length and on the presence or absence of fruit. The mean number of leaves per cluster for all types combined increased until mid July but no further increase occurred after that. The variation in leaves per cluster on the longer clusters, however, continued throughout the summer even though the mean number of leaves per cluster did not.The relative abundance of each of the arthropod species, whether it was identifiable to name or not, was given a quantitative rating by using random clusters as a common sampling unit. Eleven orders, 38 families, and over 100 species were recorded. The species making up the fauna were nearly all at a low density and in general remained low during the study. All the common pests were found but only four were at a level where economic damage to the foliage resulted. Very few of the species were present in numbers sufficiently large for analysis of the factors influencing their population density or theirA list is given of those species which were sufficiently abundant to show that differences in preference for some cluster types over others is common.


Dizziness is the one of the major complaints encountered in medical emergency rooms, and sometimes, the cause of the dizziness may be life ― threating and/or result in serious sequelae. We analyzed the data of the patients with acute dizziness who were brought by emergency transportation to out hospital. We provided clinical information about these patients to the resident doctors and conducted a questionnaire survey of the resident doctors to enquire about their general practice for cases of acute dizziness. A total 224 patients with acute dizziness patients referred to our hospital were enrolled in this study. We studied the patient's background, symptoms associated with dizziness, and diagnosis in the hospitalized cases. A questionnaire on acute dizziness care was administered before and after the lecture on acute dizziness care. Among the 224 patients transported to our hospital for acute dizziness, 93 ( 41.5% ) required hospitaliza-tion. Thirty ― eight patients were hospitalized for peripheral dizziness, 29 for central dizziness, 15 for other systemic diseases, and 11 for unknown causes. The questionnaire survey of 42 resident doctors indicated that the majority were interested in acute dizziness care, but felt that they did not have sufficient knowledge on acute dizziness. We consider that appropriate diagnostic skill to differentiate among the different causes of dizziness is mandatory in acute dizziness care. We were able to share information about acute vertigo care by providing feedback from the results of this study to the resident doctors and emergency physicians.


This paper complements earlier studies on ethnic minority underdevelopment in Vietnam by empirically examining the ethnic wage gap in the Vietnamese labour market, using data from a large-scale household survey conducted in 2002. The paper uses the 'index number' decomposition method suggested by Oaxaca (1973) to decompose the ethnic wage gap into treatment and endowment effects at both the mean and at selected quantiles of the conditional wage distribution. The results confirm the existence of an ethnic wage gap in the labour market, through this gap is found to be substantially narrower than the ethnic gap observed using household living standard measures for Vietnam. Decomposition results reveal that the ethnic wage gap is largely attributable to differentials in the returns to endowments, a finding invariant to whether the mean or selected quantiles of the conditional wage distribution is examined.


Author's summary The 43% of patients with congenital heart disease suffer from more than mild erectile dysfunction (ED) according to our questionnaire-based analysis. Advanced age, being single, fear of sexual activity due to congenital heart disease itself, psychiatric disorder and antiarrhythmic drug therapy are predictors for ED in this unique patient cohort. Overall, 29.6% of patients would appreciate an active approach by their health care provider to discuss sexual life. As a result of our analysis, erectile function as one parameter defining quality of life should be assessed routinely in clinical practice.


In September 2007 the Austrian oil and gas company, OMV, issued a declaration of intent to merge with its Hungarian competitor, MOL. The merger was regarded by MOL as a hostile takeover bid and it initiated a series of measures designed to defend its independence and position within the Central European energy market. These measures, while intended to shore up MOL's defences in the face of an increased threat of merger and acquisition from larger companies aided by the demands of the EU to liberalise the energy market, reflect the rising instance of economic nationalism within the EU and have specific implications for the promotion of solidarity at an EU level. At the same time they also reflect the increased securitisation of energy. This is important when you consider that the actions of multiple players in the battle for MOL, including Russia through involvement of Surgutneftegaz following its purchase of a series of MOL shares in March 2009, has effectively created an energy security dilemma, whereby the actions of one actor to increase its own security leads to retaliatory actions by a second actor threatened by the actions of the first. Within the Central European energy market this is happening on multiple levels and impacts the relations between EU member states, the EU and Russia. The article uses the MOL case to highlight how the geopolitics of merger and acquisition in the Central European energy market means it effectively operates in a state of persistent insecurity.


The concrete dam can prevent flooding events and generate a vast amount of electricity, and it is a critical national infrastructure. However, it is easy to get cracked, and cracks usually pose significant potential threats to the safety of the concrete dam. Many researchers have done much research on dam crack protection and explored various rules to protect the concrete dam from cracks. However, the complex and irregular distribution of cracks make this task a very challenging research issue. In this paper, the feature importance of crack influencing factors is firstly analyzed. Then, the Recurrent Neural Network (RNN) is introduced for dam crack modeling. Next, the crack width of the Longyangxia Dam is modeled and tested by using the Gated Recurrent Unit (GRU) and Long Short-Term Memory (LSTM). Finally, experimental results show that our proposed RNN-based method can effectively predict the crack change of the concrete dam.


In this work, a two-dimensional finite element model for the grain boundary flow rule is developed based on the thermo-mechanical gradient-enhanced plasticity theory. The proposed model is temperature-dependent. A special attention is given to physical and micromechani-cal nature of dislocation interactions in combination with thermal activation on stored and dissipated energy. Thermodynamic conjugate microforces are decomposed into energetic and dissipative components. Correspondingly, two different grain boundary material length scales are present in the proposed model. Finally, numerical examples are solved in order to explore characteristics of the proposed grain boundary flow rule.


Takayasu arteritis (TA) is a true orphan disease. There are no published controlled clinical trials and the evidence on which to develop management strategies and therapeutic guidelines is rudimentary, particularly when compared to the advances seen in other vasculitides and inflammatory rheumatic diseases1. Additional significant challenges to more effective management exist. These include a lack of awareness of the disease and a resultant delay in diagnosis, as well as the absence of gold standards for the quantification of disease activity and imaging2. However, the outlook is beginning to change for the better, with early evidence pointing towards improved outcomes for patients3. This improvement reflects earlier use of combined immunosuppression and the increased availability of noninvasive imaging modalities, particularly 18F-fluorodeoxyglucose positron emission computerized tomography (18F-FDG-CT-PET), high-resolution ultrasound (US), magnetic resonance, and CT angiography (MRA and CTA).

Perhaps in light of the paucity of clinical trial evidence, corticosteroids remain the mainstay of therapy and achieve remission in 60% of cases4. However, when tapered, most patients relapse. Our practice is to initiate combination immunosuppressive therapy at diagnosis to optimize control of disease activity and steroid-sparing2. Small open-label studies support the efficacy of methotrexate, azathioprine, and mycophenolate5. Although cyclophosphamide is typically reserved for refractory or life-threatening disease, we have some concerns about its efficacy in TA, and its use is often contraindicated due to a need to preserve fertility in this young, predominantly female, patient group. Despite optimal combination immunosuppression, up to 30% of patients fail to respond adequately.

This observation led to the investigation of biologic therapies already available for other rheumatic diseases. Nearly a decade ago Hoffman and colleagues reported the initial open-label study demonstrating the efficacy of tumor necrosis factor-α (TNF-α) blockade in TA6. Since …

A chemically modified carbon paste electrode with 2,7-bis(ferrocenyl ethyl)fluoren-9-one (2,7-BFEFMCPE) was employed to study the electrocatalytic oxidation of ascorbic acid in aqueous solution using cyclic voltammetry, differential pulse voltammetry and chronoamperometry. The diffusion coefficient (D=1.89×10−5 cm2 s−1), and the kinetic parameter such as the electron transfer coefficient, α (=0.42) of ascorbic acid oxidation at the surface of 2,7-BFEFMCPE was determined using electrochemical approaches. It has been found that under an optimum condition (pH 7.00), the oxidation of ascorbic acid at the surface of such an electrode occurs at a potential about 300 mV less positive than that of an unmodified carbon paste electrode. The catalytic oxidation peak currents show a linear dependence on the ascorbic acid concentration and linear analytical curves were obtained in the ranges of 8.0×10−5 M–2.0×10−3 M and 3.1×10−5 M–3.3×10−3 M of ascorbic acid with correlation coefficients of 0.9980 and 0.9976 in cyclic voltammetry and differential pulse voltammetry, respectively. The detection limits (2δ) were determined to be 2.9×10−5 M and 9.0×10−6 M with cyclic voltammetry and differential pulse voltammetry, respectively. This method was also examined for determination of ascorbic acid in pharmaceutical preparations.


For a single channel rolling missile,the autopilot structure was constructed in body coordinate system.By rolling transfer of coordinate system,the structure loop was transferred to quasi-body coordinate system and was simplified.Then the autopilot structure was designed in quasi-body coordinate system.It is notified that the cross couplings between the vertical and lateral motion exist in the autopilot loop of quasi-body coordinate system.To eliminate the cross couplings,decoupling control of autopilot loop was implemented by means of series compensation.Simulation results prove that the design method presented in this article is feasible.


Biomedical signals are measurable time series that describe a physiological state of a biological system. Entropy algorithms have been previously used to quantify the complexity of biomedical signals, but there is a need to understand the relationship of entropy to signal processing concepts. In this study, ten synthetic signals that represent widely encountered signal structures in the field of signal processing were created to interpret permutation, modified permutation, sample, quadratic sample and fuzzy entropies. Subsequently, the entropy algorithms were applied to two different databases containing electroencephalogram (EEG) signals from epilepsy studies. Transitions from randomness to periodicity were successfully detected in the synthetic signals, while significant differences in EEG signals were observed based on different regions and states of the brain. In addition, using results from one entropy algorithm as features and the k-nearest neighbours algorithm, maximum classification accuracies in the first EEG database ranged from 63% to 73.5%, while these values increased by approximately 20% when using two different entropies as features. For the second database, maximum classification accuracy reached 62.5% using one entropy algorithm, while using two algorithms as features further increased that by 10%. Embedding entropies (sample, quadratic sample and fuzzy entropies) are found to outperform the rest of the algorithms in terms of sensitivity and show greater potential by considering the fine-tuning possibilities they offer. On the other hand, permutation and modified permutation entropies are more consistent across different input parameter values and considerably faster to calculate.


At European contact, Native American agriculturalists in both eastern North America and Middle America (Mexico and Central America) relied primarily on a group of three crops: maize, squash, and beans. The widespread geographical occurrence of this agrarian triad in historical times would seem to suggest its considerable antiquity in the New World. While archaeological investigation indicates that each of the crops was domesticated in the Americas thousands of years ago, it also indicates that times of domestication and times of diffusion were substantially different for each (Smith 2001). This study presents linguistic evidence bearing on the prehistoric chronology of one of these crops, the common bean (Phaseolus vulgaris L.).


In the present research, thin films of magnesium doped ZnO were elaborated at a
concentration of 0.65 M, which were synthesized using the sol - gel method deposited on
quartz substrates of dimensions 11mm x 11mm x 2mm by spin - coating. It was possible
to evaluate the influence of the effect of the annealing temperature (400, 500 and 600 °
C) and the molar percentage of the dopant (2, 4, 6 and 8%) on the electrical (conductivity)
and morphological properties specifically the grain size. It was found that the thin films
of ZnO show the best electrical conductivity doped at 2% Mg and without doping 0% Mg
being (8.55 and 8.77) 10-7Ω-1cm-1 respectively at an annealing temperature of 600 ° C and
the lowest electrical conductivity is given to a doping of 8% Mg with a value of 1.48 x
10-7Ω-1cm-1 at an annealing temperature of 400° C, thus determining that the Conductivity
is inversely proportional to the concentration of magnesium and directly proportional to
temperature, this electrical property was measured by the four-point method of Lord
Kelvin. It was also found that the greater grain size of the ZnO films were given at a
doping of 2% Mg and without doping 0% Mg with values of 38.56 and 40.10 nm
respectively at an annealing temperature of 600 ° C and the smaller grain size was given
for a doping of 8% at an annealing temperature of 400 ° C being 14.13 nm, so that the
grain size grows as the temperature increases, but decreases as the molar Mg
concentration increases, the grain size was determined by the Scherrer equation for the
plane (002) that was found when performing XRD, the results of this technique also
showed that all the thin ZnO films doped with Mg have a wurtzite hexagonal structure
with an orientation preferential to the plane (002). Further, an optical property such as
transmittance with the UV-visible spectroscopy technique was evaluated to determine the
existence of zinc oxide and the width of the "band gap" of the thin films of ZnO by the
tangent method where it was observed that the band gap increases with increasing Mg
concentration, but decreases with increasing annealing temperature.


The implementation experiences of a new asynchronous online inter-university creativity course-titled "Creativity, responsibility, and entrepreneurship" will be presented through the lens of the course designer. Aside from introducing the identified challenges of how the regular on-site courses can be adjusted to the needs of remote education, with the aim to reach a high completion rate, the main focus remains the introduction of the different level abilities of the students in relation to social responsibility. The unique patterns of positioning the course among its internal and external competitors are created from the combination of theoretical and methodological approaches while also considering the special attitudes of the prospective Eastern European entrepreneur and social responsibility as a distinctive character. Since there was no evidence from the students on how positive social impact as a value in entrepreneurship can be ensured through online courses, the analysis of this potential effect could rely on multiple data sources from a questionnaire, answers to a quiz, and targeted analysis of the final assignments. The aim to improve new iterations call for qualitative data collection. The experimental consequences can guide the prospective course designer through the most important steps of establishing a new online course that leverages the uncommon approach that social responsibility can be an unmissable factor in the competition.


The assessment of criminal psychopathy using the Psychopathy Checklist of Hare is based on a file review and a structured interview. However, the inmate may not always be accessible for the interview and researchers may have to rely on ratings obtained through a comprehensive file review alone. The present study investigates the reliability of ratings based on file review alone. Psychopathy Checklist ratings for 56 subjects were obtained with and without the structured interview. Reliable ratings on the Checklist and accurate classification of inmates were obtained without the interview. Ratings obtained without the interview tended to give a slightly more conservative estimate of the size of the group high in psychopathy.


The incidence of malignant melanoma is rising steadily, and advanced melanoma remains one of the most lethal forms of cancer (Sung et al., 2021). The development of immune checkpoint inhibitors and targeted therapies has prolonged the survival of melanoma patients (Rutkowski and Czarnecka, 2023; Qin and Zheng, 2023; Rizzetto et al., 2023). However, drug resistance develops in the majority of patients and new strategies with a significant impact on the treatment outcome are in demand. This points to the need for robust predictive biomarkers and new rational targets for more effective combination therapies. A major problem in cancer treatment, particularly with the use of conventional chemotherapy, is the emergence of small subpopulations of cells called persister cells (Ramirez et al., 2016), which are associated with the occurrence of relapse. In the case of melanoma, these therapies are not often used due to high recurrence rates. Karki et al. defined the metabolic mechanisms of melanoma persister cells derived from gemcitabinetreated melanoma cell cultures. They concluded that chemotherapeutic agents promote the formation of persister cells. Furthermore, metabolic profiling of melanoma persister cells revealed that the metabolic alteration was associated with an upregulation of the utilisation of Krebs cycle metabolites and this appeared to be independent of drug concentration and treatment time. Hence, they point the way to targeting persister cell metabolism as a therapeutic strategy. To address the issue of low efficacy of immunotherapy in melanoma, Lin et al. hypothesized that estrogen may affect the tumor microenvironment (TME), thereby influencing its response to this therapy. Using RNA sequencing data from 4 immunotherapy-treated melanoma datasets and TCGA data of melanoma, they constructed an 11-gene estrogen response-related signature to predict response to immunotherapy in melanoma. They also investigated the feasibility of combining endocrine therapy with immunotherapy. In the same direction, Xu and Guo presented FCGR1A, encoding the CD64 transmembrane glycoprotein, as a novel potential biomarker in four types of cancer (cervical and endocervical cancer, cholangiocarcinoma, kidney renal OPEN ACCESS


Objective To study the role of intercellular adhesion molecule-1 (ICAM-1) in theprocess of hepatocellular cancer (HCC) metastasis and the probability of ICAM-1 as a marker to predictHCC metastasis. Method Tissue ICAM-1 expression in liver cancer of different growing stages wasdetected by using dot immuoblot. Result Tissue ICAM-1 expression in liver cancer was obviously positively related with tumor growing stage (r=0. 88, P0. 01),tumor size (r=0. 05, P0. 01). TissueICAM-1 expression was increased suddenly when metastasis happened and then kept in high level. Tissue ICAM-1 was higher in metastasis HCC than in mon-metastasis HCC (P0.01), higher in multisitemetastasis HCC than in monosite metastasis HCC (P0. 05). Conclusion Tissue ICAM-1 expressioncould reflect the growth and metastasis of HCC, and might be used as a marker for HCC metastasis.


Moscow's historical museums reflect a complex interrelationship of power, knowledge, and memory in contemporary Russia. Social and political changes in the country have produced enormous rifts between new and old values and memories, and the museums as mediums for the interpretations of die past are prone to manipulation by different political forces. History is contested. However die Moscow historical museums, especially those that belong to die state, still do not demonstrate a fundamental break from Soviet interpretation of the past. At best they are only beginning to develop a multi-focused approach to the Russian and Soviet past. (Moscow, museums, politics, contested history, collective memory]


This study reports on coaching for English speaking and self-directed language learning (SDLL) conducted in a blended learning environment. Twenty-eight Korean university students participated in a 13-week English coaching program. The learners completed an English speaking pre-test and a questionnaire on SDLL capacity. Then, they practiced English speaking independently using computer software and interacted with a coach as a group on a weekly basis. There were two groups. Group 1 received questions revolving around their personal lives in relation to the English stories they read online. In contrast, Group 2 learners were given questions to deepen their understanding of the stories. Both groups were told to keep a weekly planner and a journal to raise their SDLL awareness. Finally, the learners completed an English speaking post-test, the SDLL questionnaire, and two exit questionnaires. The results indicated that 60.71% of the learners improved their speaking ability, but only 39.29% improved their SDLL capacity. Group 2 improved speaking more than Group 1. The exit questionnaires revealed, however, that Group 1 felt more improvement in speaking than Group 2. Further analysis found that depending on question type, learner perceptions of their coaching experience differed.

Prosthetic valve endocarditis (PVE) is one of the most severe forms of infective endocarditis. Here, we describe a case of PVE caused by Aggregatibacter aphrophilus, a member of the HACEK group of pathogens, which is a difficult pathogen to identify using conventional methods. The pathogen was identified by 16s rRNA Sanger sequencing using eight-channel capillary electrophoresis method.


In known acceleration sensors of the off angle between main sensitivity axis and the normal is only adjustable in a range of at most 20 °. Or acceleration sensors have different characteristics with respect to the three spatial axes, which places high demands on the evaluation and excludes the use in vehicles. Multiaxial monolithic acceleration sensor, comprising: - the acceleration sensor consists of several, arranged on a common substrate individual sensors each having a main sensitivity axis, - each individual sensor is suspended for rotation on two torsion spring and has a seismic mass with an emphasis on, - each individual sensor comprises means for measuring the deflection of the seismic mass, - the acceleration sensor consists of at least three identical individual sensors, - each individual sensor is eccentrically hung over its center of gravity and - turned over the other individual sensors by 90 °, 180 ° or 270 °. The invention is particularly suitable for high-quality, stable offset capacitive sensors for use in vehicles.


This paper stipulates conditions for identifiability of the parameters of a cointegrated VAR model under general linear restrictions, possibly including cross-equation restrictions. An algorithm is given to obtain the maximum likelihood estimators under such restrictions on both the cointegrating vectors and the adjustment parameters. Then the asymptotic distribution of the estimator and of the likelihood ratio statistic for the over-identifying restrictions is given. The importance of the observed information matrix for identification issues is emphasized.


The Cattle Egret (Bubulcus ibis) now seems to be established in northern and western M6xico. Zimmerman (Condor 75:480, 1973) reported numerous sightings in Coahuila in 1971 and 1972, and in Chihuahua, Nuevo Le6n, and San Luis Potosi in 1972. On the western mainland the Cattle Egret was reported in Sinaloa (Alden, Finding the birds in western Mexico, Univ. Arizona Press, 1969) and Guerrero (Dickerman, Wilson Bull. 76:290, 1964) in 1964, and in Chiapas (Hubbard, Wilson Bull. 78: 121, 1966) in 1965. Other records also exist (Hubbs Condor 70:92, 1968). In Baja California the only records we are aware of are those of Hubbs. One, near the southeastern extremity of the peninsula, is a sight record by A. J. Sloan who, in 1964, found the species in a mangrove lagoon near the south end of Isla San Jose, in the Golfo de California. The other was based on a newspaper photograph which showed a lone Cattle Egret onboard a sport fishing boat off northwestern Baja California near Punta San Isidro in 1967. The nature of these records and the importance of documenting the occurrence of the Cattle Egret for studies on the dynamics of range expansions prompt us to report our observations of this species in Baja California. On 8 May 1973, while working in the vicinity of Guerrero Negro, Baja California Sur, midway down the Pacific coast of the peninsula, we observed three Cattle Egrets feeding in a dry, scrubby field adjacent to a canal. On 9 May, a flock of at least five was seen in a similar habitat and one female was obtained. This specimen is now in the Santa Barbara Museum of Natural History and bears the following information: SBMNH 2366; wt. 380 g; bill orangeyellow, irides yellow, tibiotarsus mostly yellow, tarsometatarsus and feet black; largest ovum 2 mm; stomach contained several grasshoppers, two lizards (Uta stansburiana, 135 mm long; Sceloporus sp., 155 mm), and one lizard tail. Most of Baja California is arid and sparsely populated. The area around Guerrero Negro, however, is lowland adjacent to Scammon's Lagoon and has isolated mangrove swamps, Salicornia salt marshes, and canals leading to man-made embayments. No domestic animals were seen. The reproductive condition of the specimen we obtained suggests that these egrets may have been stragglers in that region. Even though the first observation of the Cattle Egret off western Baja California was made five years earlier than ours, there is no indication that the species is now established on the peninsula. We did not see other Bubulcus ibis during May 1973, while working in coastal marshes and lowland habitat near La Paz (5 May), Muleg6 (6, 7, 11, and 12 May), San Ignacio (10 May), Magdalena Bay (13 and 14 May), Bahia San Quintin (21 and 22 May), and south of Mexicali (23 May). Throughout our stay in Baja California we were accompanied and aided by Jos6 Torres Ayala and Felipe Viramontes V., students at the Universidad de Nuevo Le6n, Monterrey; we are also indebted to Arturo Jimenez G. of that Universidad.


The long awaited commentary by W. D. Davies and his associate Dale Allison makes an auspicious start with this first volume. Long recognized for his careful and meticulous scholarship, Davies' encyclopedic work evidences his mastery of the vast material on the interpretation of the First Gospel. While the commentary is not written as a resource for preachers (as indicated in the preface: "our aim has been to be loyal to the tradition of disinterested and objective study in biblical criticism" [po xil), it nevertheless will be valuable to informed pastors and students as well as the scholarly community. The massive 148 page introduction will prove a valuable resource for all interested in the interpretation of Matthew. This detailed analysis is what we have come to expect from Professor Davies' pen. Invaluable treatments of the Jewish background material, the linguistic data, and the historical and current strands of interpretation are characteristic of the Book Reviews Review and Expositor. 89 (1992)


The Proserpina narrative in the Metamorphoses has not lacked for critical attention in the twentieth century. The presence of an apparently contemporaneous1 "companion" version in Ovid's Fasti (4.417-620) has inevitably prompted comparative studies, often along generic lines.2 In this paper, I shall follow the recent trend towards narratological readings of the Metamorphoses episode,3 with the aim of demonstrating a fundamental difference between the two narratives. In particular, I will show that the presence of a particularly influential internal audience in the Metamorphoses version profoundly affects the telling of the tale, prompting a radical departure from all other known versions of the Proserpina myth.4 As Ahl (1985: 202-203) has observed, "in contemplating any tale told in the Metamorphoses by a character within the work, we must consider not only what Ovid wishes to suggest to us but what the secondary narrator seeks to suggest to his audience." The Proserpina narrative, an entry in a poetic contest, is an obvious case in point. The narrator here is the Muse Calliope,5 who has been challenged to a story-telling contest by the Pierides. The stakes are high, since if Calliope loses the challenge she and her sisters must surrender control of the Heliconian fount (cedite victae /fonte Medusaeo et Hyantea Aganippe, 5.311-312), the mythical source of poetic inspiration. So clearly the gloves are off, and the Muse is playing for keeps. But the critical detail is that nymphs are designated as the judges of the contest: dirimant certamina nymphae (5.314). With this in mind, Calliope selects her narrative and, more importantly, alters story-line and emphasis to gratify the


Effects of mass fraction of sintering additives and the ratio between Y 2O 3 and La 2O 3 on the microstructure and mechanical properties of Si 3N 4 were studied. The results show that the flexual strength and fracture toughness of the ceramics reach the peak value when the mass fraction of sintering additives is 15%. The optimum composition is 5%Y 2O 3 +10%La 2O 3+85%Si 3N 4, and the materials made from this composition exhibit the best performances with the flexual strength of 911.3 MPa and the fracture toughness of 10.02 MPa·m 1/2 . In addition, the relation between microstructure and mechanical properties of self reinforced Si 3N 4 were discussed. It is found that the microstructure with a distinct bimodal size distribution of grain diameters is beneficial to the mechanical properties of β -Si 3N 4 ceramics.


This article reflects on Benjamin's critical theory of culture and modernity as a contribution for professionals and researchers of child education. Exploring the polysemy of the concept of experience in Benjamin work, it develops the idea of child experience (consisting of a mixture of complexity and subtlety), with the help also of texts produced by the critics of the culture and modernity theory. It ends emphasizing Walter Benjamin's contributions for the childhood education field, seeing it as a relational space that contributes to the development of contemporary childhood.


Incidents related to impaired human performance in space operations can be caused by environmental conditions, situational challenges, and operational deficiencies. Detecting, reporting, and correlating related incidents are key to preventing future incidents. NASA has made significant progress in standardizing the reporting of space incidents by developing electronic data entry and storage of information. TRACLabs is investigating the use of semantic web technology to improve incident reporting at NASA. Capturing incident data in semantic terms should improve search by providing a rich set of relationships among data within a single incident as well as across multiple incidents. The use of ontologies also enables using more advanced software techniques to find similarities among incidents. The semantic language and tools for incident reporting developed under this project are complementary but not duplicative with current incident reporting approaches such as the Problem Reporting and Corrective Action (PRACA) process for system design issues in Shuttle and Station. This technology is intended to support user groups that have specific information needs not well addressed by programmatic incident reporting systems like PRACA. For example, the space human factors organization needs to track incidents related to human factors and habitability issues that are not well represented in current incident archives.


The conditions which comprise the group known as the 'myeloproliferative disorders' are characterized by quantitative and qualitative abnormalities in the proliferation of haemopoietic cells for which no demonstrable cause is evident (Dameshek, 1951). It is not known at present whether any common aetiological factor unites the group: the essential basis for their being classified together lies in the abnormal proliferative tendency which extends to cells, such as the fibroblast and reticulum cell, which do not enter the peripheral blood. The various conditions differ not only in the combinations of cell-lines involved but in the degree of maturation of the most prominent cells affected, so that both acute and chronic forms of disorder may be distinguished. The classical types of chronic myeloproliferative disease consist of polycythaemia vera, chronic myeloid leukaemia, essential thrombocythaemia, and primary myeloid metaplasia, while the acute forms include acute myeloblastic leukaemia, acute myeloid metaplasia, and the variants of the Di Guglielmo syndrome. As was strongly emphasized by Hutt, Pinniger, and Wetherley-Mein (1953), combinations of features frequently occur which overlap the conventional descriptions of these conditions, and the wide spectrum ofclinico-pathological patterns includes many cases which lie between these categories. It is an essential part, however, of the study of disease to distinguish groups of cases showing common features, and to determine the significance of such groupings in terms of sequelae, prognosis, and pathological correlations. To be most useful, the criteria must be carefully selected,


40 individuals of Glassland Red Cattle (GLRC) and its hybrid with Limousine (LM) were chosen as test population in this (study.) The muscularity evaluation traits in the regulation of linear valuation and slaughtering meat traits were used to evaluate their beef performance traits, and the body measurements traits and body weight were used to evaluate their growth and development. The relationship of 21 traits in a population of 40 cattle and 8 microsatellite makers were analysised by SPSS. The results showed that, for microsatellite loci IDVGA55, allele C (203bp) had a positive correlation with Body height, Height at hip cross (HHC) and height at capitulum body measurement traits. For BM2113, allele C (142bp) had a positive correlation with gam girth, net meat weight and net meat rate. For ETH225, allele A (123bp) had a positive correlation with waist corner width. For IDVGA46, allele C (211bp) had a negative correlation with the five muscularity evaluation and four slaughter meaty traits. For BM1824, allele A (171bp) had a positive correlation with Height at hip cross (HHC) and Loin thickness, and allele C (179bp) had a positive correlation with Chest depth. For TGLA44, allele E (221bp) had a positive correlation with meaty traits.


We present the mathematical study of a computational approach originally introduced by R. Cottereau in [R. Cottereau, IJNME 2013]. The approach aims at evaluating the effective (a.k.a. homogenized) coefficient of a medium with some fine-scale structure. It combines, using the Arlequin coupling method, the original fine-scale description of the medium with an effective description and optimizes upon the coefficient of the effective medium to best fit the response of an equivalent purely homogeneous medium. We prove here that the approach is mathematically well-posed and that it provides, under suitable assumptions, the actual value of the homogenized coefficient of the original medium in the limit of asymptotically infinitely fine structures. The theory presented here therefore usefully complements our numerical developments of [O. Gorynina, C. Le Bris and F. Legoll, SIAM J. Sci. Computing 2021].


We present a new solver for nonlinear parabolic problems that is L-stable and achieves high order accuracy in space and time. The solver is built by first constructing a single-dimensional heat equation solver that uses fast O(N) convolution. This fundamental solver has arbitrary order of accuracy in space, and is based on the use of the Green's function to invert a modified Helmholtz equation. Higher orders of accuracy in time are then constructed through a novel technique known as successive convolution (or resolvent expansions). These resolvent expansions facilitate our proofs of stability and convergence, and permit us to construct schemes that have provable stiff decay. The multi-dimensional solver is built by repeated application of dimensionally split independent fundamental solvers. Finally, we solve nonlinear parabolic problems by using the integrating factor method, where we apply the basic scheme to invert linear terms (that look like a heat equation), and make use of Hermite-Birkhoff interpolants to integrate the remaining nonlinear terms. Our solver is applied to several linear and nonlinear equations including heat, Allen-Cahn, and the Fitzhugh-Nagumo system of equations in one and two dimensions.


Fault occurrence in power systems could result in losing their stability and cause severe damages in faulted devices or adjacent healthy devices. Also, stability proposition is charged as an important component in energy management and planning of power systems. Moreover, during the motor starting period, it draws a large current from the system, results in voltage drop of system and poses disturbances to the normal operation of other loads. Hence, fault and induction motor starting analysis are important studies in design and development of power systems. Beside, conversion of 3-phase double-circuit (3PDC) to 6-phase single-circuit (6PSC) line is a well known method to increase the power transfer capability of the network. So in this paper, an investigation of fault occurrence and motor starting for 3PDC converted to 6PSC transmission line is studied. According to the achieved results, if network is converted to 6PSC network, then system performance from view of transient stability and motor starting could improve, but magnitude of fault current may be increased than the 3PDC network. In this study, power system is assumed as a balanced system. Other economical and practical factors can be studied for planning, development and design of future transmission networks.


GRAPHICAL ABSTRACT Abstract We investigated the POCl3-mediated transformation of aromatic bisulfite adducts to the corresponding 5-arylidenethiazolidine-2,4-diones. The in situ transformation of an aromatic bisulfite adduct to the parent aldehyde in a non-aqueous non-polar solvent (toluene) was demonstrated using DoE (Design of experiment), offline 1H NMR, online ReactIR, HPLC, LC-MS, and GC-MS. By means of these analytical tools, we determined, for the first time, the structure of the intermediate species (aldehyde) prior to the carbon–carbon double-bond formation. The carbon–sulfur bond undergoes a fast cleavage, immediately after the addition of POCl3, which finally affords the corresponding 5-arylidenethiazolidine-2,4-diones.


The main objective of this paper is to critically assess the dominant additive theory of the formation of Customary International Law by using the concept of discursive normative practice and the work of Gerald Postema. My central conclusion is that the use of this concept provides an explanation of the process of formation of Customary International Law that is superior to the additive theory which consists of two elements - practice and opinio juris. On the other hand, Postema's theory also has its own weaknesses, and this paper explores ways to improve it.


Meningitis after spinal anaesthesia is a rare yet devastating complication of spinal anaesthesia. The exact incidence is unknown. Our patient developed signs and symptoms of meningitis 48 hours after spinal anaesthesia and required intensive care unit admission. Her cerebrospinal fluid was sterile. Computed tomography of brain showed left subdural collection. She recovered well after 6 weeks of intravenous antibiotics. No neurological sequela noted from subsequent follow-up examinations. Our case provides an important insight of meningitis with subdural collection after spinal anaesthesia for emergency caesarean section.


Recent studies show that localized crustal magnetic fields on the lunar surface can reflect a significant portion of the incoming solar wind protons. These reflected ions can drive a wide range of plasma waves. It is difficult to determine the intrinsic properties of low‐frequency waves with single‐spacecraft observations, which can be heavily Doppler shifted. We describe a technique to combine trajectory analysis of reflected protons with the Doppler shift and resonance conditions to identify ultralow‐frequency waves at the Moon. On 31 January 2014 plasma waves were detected by one of the Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun (ARTEMIS) probes as it approached the lunar wake; these waves were not detected by the second ARTEMIS probe located upstream in the undisturbed solar wind. The observed waves had a frequency below the local ion cyclotron frequency and had right‐hand circular polarization in the reference frame of the Moon. By solving the Doppler shift and the cyclotron resonance equations, we determined the conditions for reflected ions to excite the observed waves. Simulated trajectories of reflected ions correspond to ARTEMIS ion observations and support the hypothesis that reflected ions are the primary driver of the waves. By combining trajectory analysis with the resonance conditions, we identify scenarios where ions that satisfy the resonance conditions are present in the right location to generate the observed waves. Using this method, we can uniquely identify the observed waves as upstream propagating right‐hand polarized waves, subject to the assumption that they are generated by cyclotron resonance with ions.

Abstract The copolymerization of isoprene or butadiene with acrylonitrile in the presence of zinc chloride or ethylaluminum sesquichloride, in the presence or absence of a free radical catalyst, at 30-70°C yields an equimolar, diene-acrylonitrile alternating copolymer containing more than 90% trans-1,4 unsaturation, irrespective of monomer charge. The copolymer results from the homopolymerization of a diene-acrylonitrile…metal halide transoid charge transfer complex. When ZnCl2 is the electron-accepting metal halide and the polymerization is carried out at temperatures of 50°C and higher or to high conversions, the equimolar copolymer is accompanied by a high acrylonitrile polymer, and in the presence of a radical catalyst, by a normal radical copolymer. In the presence of the organoaluminum halide and in the absence of a radical catalyst, the alternating copolymer is the only product, irrespective of monomer charge. However, in the presence of a radical catalyst and at high acrylonitrile monomer charges,...


Molybdenum nucleus has many natural and artificial isotopes important for fundamental and applicative researches. Cross sections, angular correlations and isomer ratios in fast neutrons induced reactions up to 25-30 MeV were evaluated using codes realized by authors as well as dedicated software. Contributions of different nuclear reaction mechanisms in the cross sections were also determined. Parameters of nuclear optical potential, density levels and radius channels were extracted. Theoretical evaluations were compared with existing experimental data. The results of present work were realized in the frame of the fast neutrons scientific program at FLNP basic facilities (IREN and EG5) and are necessary for future experiment preparation.


ABSTRACT The decree of 4 July, 1974, by President Kenyatta, proclaiming Swahili as the national language of Kenya is discussed with reference to questions of feasibility and expediency. The alternatives to the President's decree are considered, and reasons for the decision are suggested. Comparison of the status of Swahili in the capital cities of Kenya (Nairobi) and Tanzania (Dar es Salaam) is made to illustrate the special difficulties confronting the Kenya government in making the President's decree effective. The parliamentary response is crucial, but the dominance of English in Nairobi, the capital city, where Swahili has not always been much valued, indicates a wider gap between intention and the possibility of fulfilment than in Dar es Salaam. The need for proficiency in Swahili is viewed in the Kenya situation, and this is related to what is linguistically appropriate. The nationalization of Swahili results in secularization of a language that found its normal expression in the setting of Islam. What is linguistically appropriate in Swahili on the national level is often inappropriate to members of the Swahili coastal community. Kenyans are likely to opt for their own modifications of Standard Swahili, basing this on the Mombasa dialect, but up-country Swahili is the foundation upon which greater proficiency can be achieved.

Introduction/Background Simulation is being used increasingly as a tool to assess new clinical spaces.1,2 In a tertiary pediatric center, in-situ simulation testing was essential to the conversion of a 24-bed combined pediatric/adult unit to a 33-bed pediatric emergency department (PED). A key challenge during the testing phase was to identify the best way to reflect both the patient and work flow in this dynamic, high turnover, clinical area. The most prevalent testing technique involves performing multiple predetermined varied scenarios; each designed to assess different objectives. This method, however, limits the ability to test patient flow-related issues. Therefore, we purposed to find an optimal way to replicate a typical day in the PED. We report the novel use of simulation using the 'mirror technique' to concurrently assess the impact of environmental changes on work processes and flow in the PED. Methods A four-hour continuous simulation was conducted using the 'mirror technique', wherein the Existing PED (E-PED) environment was replicated in real time in the new ED space through the use of simulation. An interprofessional operating team of stakeholders and simulation experts orchestrated the day. The Simulated PED (S-PED) had a similar staff model to the E-PED, including MDs, RNs, residents, medical students, Child Life Specialists, etc. For every patient triaged in the E-PED, a second triage nurse created a duplicate, anonymized chart for the simulated patient with near identical clinical features. A simulation coordinator located in triage determined the level of fidelity to be used for each patient /parent (from 10 manikins and 15 human volunteers). A repertoire of scenarios deemed necessary, though less likely to occur on a typical day, was created preemptively to test specific resources in the PED. The mirroring principle was maintained throughout all phases of patient care. Using hand radios, information regarding the real patient (e.g. response to treatment, complications, unexpected events, investigation Results etc.) was transmitted from the E-PED to a simulation operator located in the S-PED. Real test Results were provided to the simulated patients in real time as a hard and/or soft copy. Fifteen observers were assigned to provide feedback using a specific evaluation tool designed especially for the day. Issues recorded in the observer tool and the post simulation debrief were divided into seven different categories and analyzed. Summary of the key findings were forwarded to the PED operational committee. During the four hour simulation phase, 20 patients were simulated; 16 scenarios were created using the mirroring technique, 4 were selected from the pre-made scenarios. Over 200 issues were identified from the debrief and the observer tool of which 38 were classified as critical and required immediate correction prior to occupying the new space (4 workflow, 17 patient flow and physical space, 1 transport, 7 communication, 2 resource allocation, 3 patient safety and 5 other). Based on findings, an adjustment was made to redefine the future movement and communication strategies within the department such as how patients flow from triage to rooms, communication method between ED staff, and movement of patients between hospital departments. Results: Conclusion The IHI has identified problems with patient flow as an important contributor to delays in patient care.3 Computer based simulation has been used to diagnose and improve problems with patient flow, however, to our knowledge little has been done with in-situ, high fidelity simulation. The mirroring technique can be a useful tool to assess clinical areas with high patient turnover such as emergency departments, operating rooms, intensive care units and ambulatory clinics. We believe this technique helps diagnose flow related issues that may be overlooked using traditional simulation Methods and brings simulation one-step further towards reality. References 1.

Polymer solar cells were fabricated with varying amounts of electron transporting ZnO NPs in a buffer layer located over an active layer of P3HT/PCBM incorporating a fixed amount of CuO nanoparticles. The enhanced electronic and optical properties attained by adding ZnO nanoparticles proportionally increased the power conversion efficiency by 32.19% compared to a reference cell without ZnO-NPs buffer layer. ZnO-NPs buffer layer improved the exciton dissociation rate, electron mobility, optical absorption and charge collection at the anode, resulting in higher short circuit current and external quantum efficiency. The short circuit current (Jsc) of the optimum device was measured at 7.620 mA/cm2 compared to 6.480 mA/cm2 in the reference cell with 0.6 mg of CuO nanoparticles. Meanwhile, the external quantum efficiency (EQE) increased from 54.6% to 61.8%, showing an enhancement of 13.18% with the incorporation of ZnO nanoparticle layer.


A key challenge for nanoparticles-based drug delivery system is to achieve manageable drug release in tumour cell. In this study, a versatile system combining photothermal therapy and controllable drug release for tumour cells using temperature-sensitive block copolymer coupled Au NRs@SiO2
 is reported. While the Au NRs serve as hyperthermal agent and the mesoporous silica was used to improve the drug loading and decrease biotoxicity. The block copolymer acted as "gatekeeper" to regulate the release of model drug (Doxorubicin hydrochloride, DOX). Through in vivo
 and in vitro experiments, we achieved the truly controllable drug release and photothermal therapy with the collaborative effect of the three constituents of the nanocomposites. The reported nanocomposites pave the way to high-performance controllable drug release and photothermal therapy
 system.

The relative humidity at the surface of a soil is calculated as a function of time from a realistic, exactly solvable model for unsaturated fluid flow. When the evaporation rate is constant, as in the atmosphere-controlled phase, the surface relative humidity suddenly drops at a particular time, even though the humidity–time function is differentiable. This sudden transition still occurs, but is smoother, when more realistic radiation-type boundary conditions are introduced and when the soil-water diffusivity approaches zero continuously at zero water content. In these cases, solutions are obtained by a numerical method of lines which has been validated against the analytically solvable model. A gradual decrease in surface water content is not inconsistent with a sharp, step-like decrease in relative humidity. This is due to the universal exponential Gibbs–Boltzmann relationship between relative humidity and soil-water potential. q 1999 Elsevier Science Ltd. All rights reserved.

Large-area processing of perovskite semiconductor thin-films is complex and evokes unexplained variance in quality, posing a major hurdle for the commercialization of perovskite photovoltaics. Advances in scalable fabrication processes are currently limited to gradual and arbitrary trial-and-error procedures. While the in-situ acquisition of photoluminescence videos has the potential to reveal important variations in the thin-film formation process, the high dimensionality of the data quickly surpasses the limits of human analysis. In response, this study leverages deep learning and explainable artificial intelligence (XAI) to discover relationships between sensor information acquired during the perovskite thin-film formation process and the resulting solar cell performance indicators, while rendering these relationships humanly understandable. We further show how gained insights can be distilled into actionable recommendations for perovskite thin-film processing, advancing towards industrial-scale solar cell manufacturing. Our study demonstrates that XAI methods will play a critical role in accelerating energy materials science. This article is protected by copyright. All rights reserved.


Autogenous shrinkage and dry shrinkage of cement based materials,produced by lower water/binder ratios,are the key factors resulting in the concrete early cracking.Experiments on ultra-fine fly ash(UFA) replaced 20%~40% equivalent cement and UFA blended cement mortars were conducted.Experimental results show that autogenous shrinkage(before 7-day) of UFA mortar reduces and dry shrinkage increase with increase of UFA amount under the condition of fixed water/binder ratio.On the other hand,the autogenous shrinkage of UFA blended cement mortar reduces and dry shrinkage increase with increase of water/binder ratio under the condition of variable water/binder ratio.The better linear relationship between autogenous shrinkage and dry shrinkage is shown by regression analysis.The addition of UFA reduces water demand of cement based materials under the condition of keeping the same fluidity,so early strength and long-term strength of UFA mortar catch or surpass that of reference cement mortar,solving the problem of early strength of UFA mortar being lower because of no hydrating of UFA.The microscopic test results indicate that UFA has the better effects on dense packing,water reducing,dispersing and strength increasing.
