Bill Connor, a pioneer in lipid and atherosclerosis research, passed away in Portland, Oregon, on October 25 at the age of 88. This gracious and unassuming man was an innovative biomedical investigator, stimulating teacher, and compassionate physician. His scientific curiosity and courage to challenge existing concepts enabled him to make seminal contributions to lipid metabolism and its role in cardiovascular health and disease. Bill completed undergraduate studies at the University of Iowa in 1942 and served in the United States Army Signal Corps during World War II. After receiving his MD degree from the University in 1950, he began postgraduate training, spent 2 years in private practice, and then completed a medical residency at the Iowa City Veterans Administration Medical Center. He was appointed to the University of Iowa faculty in 1956 as an Instructor in Internal Medicine and rapidly rose to the rank of Professor. Bill was a pioneer in the treatment of hyperlipidemia and achieved national recognition while at Iowa for his studies in lipid nutrition, cholesterol metabolism, and atherosclerosis. In 1975 he moved to the Oregon Health and Science University, where he maintained a vigorous and productive research program in lipids and nutrition until the time of his death. During his tenure at Iowa, Bill was Principal Investigator of a Program Project in Lipids and Thrombosis and the Arteriosclerosis Specialized Center of Research. In addition, he served as Director of the Lipid Research Clinics Program and the Clinical Research Center. Because of his widespread medical interests, infectious enthusiasm for research, and collegial manner, he attracted many faculty collaborators and was a superb role model for trainees and junior investigators. The remarkable breadth of Bill's research is documented in his nearly 400 publications, beginning in 1956 with a study of hyperlipidemia in patients with coronary disease and concluding with 2 papers that will be published posthumously in 2010: one describing the effects of lutein on macular degeneration and the other describing a diagnostic test for cerebrotendinous xanthomatosis. His level of productivity is amazing considering that much of his work involved clinical investigation in a metabolic ward setting that required timeconsuming procedures like sterol balance. Among his many important research contributions, 4 deserve special mention. Bill first achieved national acclaim for his studies of human cholesterol metabolism. When he entered the field, dietary cholesterol was not considered to be an important factor in determining the plasma cholesterol concentration. Through carefully controlled metabolic studies, Bill proved that this widely held view was incorrect. He showed that plasma cholesterol was influenced by dietary cholesterol intake and determined the threshold level and range over which this occurred in humans. As a member of 2 key National Heart, Lung, and Blood Institute advisory groups, the Diet Heart Study Committee and the Lipid Metabolism Advisory Committee, which he chaired, Bill played an important role in implementing these findings for public health policy. He also coauthored several popular cookbooks, including The New American Diet with Sonja Connor, his wife and scientific colleague, to provide the public with a practical means for applying these heart-healthy recommendations. Bill firmly believed in dietary cholesterol restriction and followed a low-cholesterol diet himself. Furthermore, he had the dietary staff prepare a low-cholesterol, high-fiber lunch for visiting colleagues to illustrate that such food was palatable and nutritious. At the end of a National Institutes of Health site visit held soon after he left Iowa, a senior committee member who had participated in several previous site visits took me aside and said that the group was very happy that Bill was no longer the Director of our Center. I was stunned and said, "Why, didn't you like his work?" He replied, "No, we always thought that Bill's research was great, but now we don't have to eat those awful soybean and onion sandwiches for lunch." What probably was Bill's most notable research accomplishment is a study performed in collaboration with Mark From Carver College of Medicine, University of Iowa, Iowa City, IA.

Low drug loading and high initial burst release are common drawbacks for most polymeric nanocarriers in their biomedical applications. This review emphasizes the use of unconventional carbonaceous nanocomposites as functional carriers to improve the drug loading capacity and their capability of protecting drugs from the surrounding environment. The unique properties of typical carbonaceous nanocarriers, including nanotube, graphene/graphite, fullerene, and nanodiamonds/diamond-like carbon, are presented. Advanced methods for the surface functionalization of carbonaceous nanocarriers are described, followed by a summary of the most appealing demonstrations for their efficient drug loading and sustained release in vitro or in vivo. The fundamental drug delivery concepts based on controlling mechanisms, such as targeting and stimulation with pH, chemical interactions, and photothermal induction, are discussed. Additionally, the challenges involved in the full utilization of carbonaceous nanocomposites are described, along with the future perspectives of their use for enhanced drug delivery. Finally, despite its recent emergence as a drug carrier, carbon-based nanocellulose has been viewed as another promising candidate. Its structural geometry and unique application in the biomedical field are particularly discussed. This paper, for the first time, taxonomizes nanocellulose as a carbon-based carrier and compares its drug delivery capacities with other nanocarbons. The outcome of this review is expected to open up new horizons of carbonaceous nanocomposites to inspire broader interests across multiple disciplines.


Two series of experiments were performed to investigate the effects of altered dietary sodium, of sodium-retaining steroids, and of increased blood pressure on rat plasma prekallikrein. Plasma prekallikrein increased with age in all groups of rats; thus all comparisons are made with age-metched controls. In the NIH strain of Wistar Kyoto spontaneously hypertensive rats (SHR/N), normotensive at 4 weeks of age, a significant and sustained elevation of blood pressure was apparent by 6-8 weeks of age. Mean plasma prekallikrein, which rose with advancing age, did not differ from that of control Wistar Kyoto NIH (WKY/N) rats during the prehypertensive (0-6 weeks of age), the early hypertensive (8 weeks) or the advanced hypertensive (13 weeks) stages. In the stage of severe hypertension (19-29 weeks), however, SHR/N rats showed significantly lower plasma prekallikrein (p < 0.05-0.005) than agematched WKY/N rats. Plasma prekallikrein was higher in SHR/N in the severe-hypertension stage given a low-sodium diet than in those given an average-sodium diet (p < 0.0 1 ), and this was also the case for the age-matched WKY/N rats on a low-sodium diet, in which plasma prekallikrein was higher (p < 0.05) than in those on average-sodium diet . In young Wistar NIH (W/N) rats given average-sodium diet, desoxycorticosterone (DOC) (27.5 mg/100 gm body weight in 2 doses) increased plasma prekallikrein (p < 0.05-0.005). When DOC was given with a high-sodium diet, however, hypertension developed (p < 0.005) and plasma prekallikrein remained normal. With a low-sodium diet alone, plasma prekallikrein in W/N rats was increased by the 10th day (p < 0.05), but had returned to normal by the 30th day. Thus plasma prekallikrein increases with age and with (exogenous or endogenous) sodium-retaining steroid, and decreases with severe hypertension.


Context: The discovery and chemical analysis of extremely metal-poor stars permit a better understanding of the star formation of the first generation of stars and of the Universe emerging from the Big Bang. aims: We report the study of a primordial star situated in the centre of the constellation Leo (SDSS J102915+172027). method: The star, selected from the low resolution-spectrum of the Sloan Digital Sky Survey, was observed at intermediate (with X-Shooter at VLT) and at high spectral resolution (with UVES at VLT). The stellar parameters were derived from the photometry. The standard spectroscopic analysis based on 1D ATLAS models was completed by applying 3D and non-LTE corrections. results: An iron abundance of [Fe/H]=--4.89 makes SDSS J102915+172927 one of the lowest [Fe/H] stars known. However, the absence of measurable C and N enhancements indicates that it has the lowest metallicity, Z<= 7.40x10^{-7} (metal-mass fraction), ever detected. No oxygen measurement was possible. conclusions: The discovery of SDSS J102915+172927 highlights that low-mass star formation occurred at metallicities lower than previously assumed. Even lower metallicity stars may yet be discovered, with a chemical composition closer to the composition of the primordial gas and of the first supernovae.

THE first suspicion that surface charge on blood cells and vessels is important in such diverse biological phenomena as diapedesis of cells in inflammatory processes, cell aggregation, and adherence to blood-vessel walls and probably also in thrombosis was voiced by Abramson in 19271 and in his later monographs.2'3 Confirmation of his suspicions has been offered by innumerable scientific groups since that time, using diverse experiments, in vitro and in vivo, relating changes in blood vessel wall surface charge to platelet adhesion and thrombus for*410 mation. Our interest in these matters began in I951 with biophysical studies to establish criteria for suitable preparation, preservation, and implantation of fresh and freeze-dried arterial grafts.1" Particular attention was devoted to the observed negative surface charge at the blood-endothelial interface in the intact vascular system in vivo, which measured I to 2 mv.,12 and the changes found during thrombosis. The electrical doublelayer phenomenon is operative at the solid-liquid interface; i to 2 mV. applied across a few angstroms corresponds to a field strength of I04 volts/cm. (Figures i and 2). With Drs. Kenneth Cole and James Pate we speculated on what effect injury and suturing might have on modifying surface-charge characteristics of the blood vessel and in the production and prevention of thrombosis.


For the second language student, proficiency is a measure of what tasks can be accomplished with acquired language and how well they can be accomplished. The necessity for specification of functional proficiency arose, and resulted in the publication of guidelines by the American Council on the Teaching of Foreign Languages (ACTFL)'s guidelines delineating functional proficiency in five areas: speaking, writing, reading, listening, and culture. This represents a paradigm shift, as communication has become the focus of language instruction. Applying instructional systems design to a proficiency oriented foreign language program is discussed in terms of the following guidelines: (1) use the ACTFL proficiency guidelines; (2) write specific performance objectives and criterion referenced test items before developing instruction; (3) make the classroom learner-centered; (4) integrate instructional materials and media; and (5) evaluate the program: both formative and summative evaluation can improve the effectiveness of foreign language instruction.

A simple model is presented for spin-wave excitations and the low-temperature magnetization of ferromagnetic ultrathin films. The films are assumed to be quasi-two-dimensional arrays of fixed magnetic moments and both exchange and dipolar interactions are taken into account. Discrete and continuous models are used to examine the wave-vector dependence of the spin-wave frequency in the long-wavelength limit. This spin-wave theory can be used to calculate the temperature dependence of the saturation magnetization in the limit of small fluctuations. The role of dipolar interactions is examined for a single monolayer and for thin films consisting of two or three atomic layers.


In order to assist federal and state decision makers, the Applied Research and Technical Support Branch (ARTSB) of the Ground Water and Ecosystems Restoration Division (GWERD) has, since 1989, developed a series of over 30 Ground Water Issue Papers intended to be brief, state-of-science documents focused on a technical issue of expressed interest and prepared in a concise and readable format. The purpose of this Issue Paper is to discuss some of the conditions under which viral contaminants may survive and be transported in the subsurface, identify sources as well as indicators of viral contamination, outline the effects of hydrogeologic settings on viral movement, and introduce the reader to the current state of virus transport modeling along with an example of modeling applications.


This study examined the associations among three aspects of self-concept (self-esteem, self-concept clarity and sexual identity confusion), self-stigma and depressive symptoms. Two hundred and eighty eight participants (163 lesbians and 125 gay men) completed an anonymous, online survey. Results indicated that individuals with lower self-esteem, lower self-concept clarity and higher sexual identity confusion reported higher self-stigma. Furthermore, the negative association between self-concept clarity and self-stigma was significant for individuals with lower self-esteem, but not those with higher self-esteem. Finally, the positive association between self-stigma and depressive symptoms was significant for individuals with lower self-esteem, but not those with higher self-esteem, and it was stronger for those with lower sexual identity confusion. The current findings highlight the importance of self-concept in the internalisation of sexual stigma and its sequelae.


Background

This study aimed to describe the general and specific context of hospitalizations for acute myocardial infarction (IAM) in the Brazilian public health system and its main indicators of economic care in the pre- and post-coronavirus-disease (COVID-19) period.
Methods

The main assistance and economic indicators of care related to IAM, together with the Brazilian public health system, were evaluated in the period between January 2011 and April 2021, comparing the pre- and post-pandemic indicators. The research figures were descriptive and exploratory, using data from the Ministry of Health. The main data evaluated were lethality, number of hospitalizations, average length of hospital stay, and hospitalization costs. The ARIMA and general regression models were used to analyze the monthly outcomes pre and post COVID-19, thus enabling the alteration of care and economic behavior of IAM cases with the public health system.
Results

Hospitalization for IAM has been on the rise for the past 10 years, with a slight decrease after COVID-19. There was an equally slight increase in lethality, with a significant decrease in the mean length of stay of hospitalized patients. The economic aspects of IAM show that more than US$ 762 million were invested during the reporting period. The average ticket presents a clear decrease in investment per capita, with a real devaluation of 70.04% in the period from 2011 to April 2021, which may be related to two main hypotheses: (1) increased effectiveness and (2) cost analysis of the effectiveness of care and/or chronic underfunding of the Brazilian public health system.
Conclusions

There was a historical increase in hospitalizations and a reduction in IAM-related deaths.


With Teaching Biblical Faith, veteran professor of Christian education Jack Seymour, from Garrett-Evangelical Theological Seminary, has written another wise and engaging book of strategies and best practices for biblical teaching for clergy and lay leaders, as well as students and professors of Christian education. Seymour demonstrates simply that Christian living is biblical living, putting faith into action. Reflecting on his own research in a local church, Seymour argues that people make sense and discover meaning through study. Through biblical study persons learn and grow in their faith, identity, and vocation, making meaning as they reflect on the biblical text and their lives. He shows them ways to do this in small groups. Seymour clearly describes and outlines each approach, then summarizes the contributions and challenges of each approach. In the first chapter, Seymour establishes the foundation by defining biblical faith as "following the tradition, seeking God's justice, and enacting the hopes of the faith in new times and new places" (8). This work helps persons reclaim their identity as children of God and their vocation as partners in God's creation. In chapter 2, Seymour suggests that intentional and sustained teaching helps persons claim and live in response to this identity and vocation. The goal then is for persons to grow in their knowledge of scripture as they seek to live biblical faith. Chapters 3–12 offer ten different approaches for persons to explore as they strive to do this holy work—approaches that include prayer, study, community, and service. Each approach invites both teacher and learner to ask questions of the text and their lives as they grow in their awareness of scripture, engage in practical reflection, and connect their faith with daily living. Chapter 13 offers insight for teachers, chapter 14 describes ways leaders can shape a biblical congregation, and chapter 15 suggests resources for a church library that will support a faith community in their biblical living. This book is not about simply acquiring knowledge, but about how biblical study leads to biblical living through mission and vocation. The author spends a significant amount of time sharing ten practical ways for the reader to engage in this process, and getting the reader to reflect on how each approach impacts their living of biblical faith. Each approach reflects different aspects of the faith tradition (including study, worship, and service), and draws on many different cultural resources including African American and Latin American traditions. The core strength of this new book lies in its practical relevance for the field of Christian education. In churches' quest to reach those who have left a faith community or who have never been a part of one, small groups of the kind Seymour suggests remain a particularly effective and transformational experience. Seymour's writing style is approachable and his suggestions are valuable for readers with varying levels of experience. For the new teacher, Seymour offers insight and tips for planning and leading the sessions. For the ministry student, Seymour asks


We investigated the phylogenetic relationships among the three presently recognized subspecies of the tadpole shrimp, Triops cancriformis, using mitochondrial 16S and 12S rDNA sequences. Our results indicate that the taxon is divided into two distinct lineages. One lineage is formed of T. c. cancriformis populations and samples from northern Spain that had been classified as T. c. simplex in the most recent literature. The second lineage comprises all populations of T. c. mauritanicus and northern African populations of T. c. simplex. These two main lineages separated 2.3 to 8.9 million years ago, based on the range of inferred molecular clocks recognized for crustacean mtDNA sequence divergence. Percentages of divergence are in the range reported for recognized species in other notostracan lineages and we therefore propose to recognize them as two species, Triops cancriformis and Triops mauritanicus. The latter would comprise two subspecies in northern Africa, one consisting of the Moroccan populations of the former T. c. mauritanicus, the other comprising the African populations of the former T. c. simplex. It also includes three as‐yet unnamed lineages. A comparison of morphological characters with the molecular data revealed that the former T. c. simplex cannot be reliably separated from T. c. cancriformis, using morphological characters that have hitherto been used to distinguish among subspecies of T. cancriformis. Our investigation is the first to demonstrate the presence of T. c. cancriformis in Africa (Tunisia). The genetic haplotypes of these populations are identical with haplotypes also occurring in Central and Western Europe, as well as in Sicily. Therefore, we hypothesize that the African populations of T. c. cancriformis represent a result of repeated long‐distance dispersal across the Mediterranean Sea.


Disclosed are a method using a primary synchronization signal (PSS) to provide indication, a base station, a terminal equipment, and a system capable of indicating an operation mode by means of locations of multiple sub-synchronization signals of the PSS in a radio frame, thereby achieving an objective of using a PSS to indicate an operation mode of a network. A method disclosed in an embodiment of the invention comprises: a base station determines an operation mode of a network; the base station generates a primary synchronization signal (PSS) according to the determined operation mode, the PSS comprising multiple sub-synchronization signals, and different operation modes corresponding to the sub-synchronization signals at different locations; and the base station transmits the PSS to a terminal equipment.


Recent economic recession has a huge affect on the construction industry, more than many other industries. In response to market conditions, construction companies hit by financially disastrous time and cost overruns. It is imperative for these companies to be prepared in every sense. Thus managements of these construction companies have to search for restructuring strategy for their survival. In order to cope up with prevailing crisis construction companies advocating decrease in their manpower resources. Further, they don't recognize the importance of employee's idiosyncratic capabilities, proprietary construction processes and equipment that cannot be obtained in the factor markets. Even though construction sector is in critical situation it has enormous future growth potential. Reducing employee's strength cannot be a remedy to present crisis. An attempt is made in this paper to develop the restructuring strategy based on theory of Resource Based View. The strategy proposes to exploit manpower capabilities of company to grab the future opportunities. The aim of the paper is to build capacity and a core competency based on Resource Based View that will induce competitive advantage and build market share of the construction companies. Resource Based View approach emphasizes the organizations own set of resources and capabilities' as a determinant of competitive advantage.


An integrated correlation scheme constructed for all microfossil and megafossil groups recovered in four DSDP holes from Leg 71 in the southwest Atlantic provides a basis for comparing Jurassic to Holocene sediment sequences in this region with others from throughout the world. The 11 fossil groups in the graphic correlation charts are benthic and planktonic foraminifers, benthic and pelagic mollusks, calcareous nannofossils, diatoms, silicoflagellates, radiolarians, dinoflagellates, pollen and spores, and sponge spicules. The use of all groups allows correlation within the province as well as with lower-latitude zonal schemes. The impoverishment and ecologic restriction of various faunas and floras and the incompleteness of some sections, however, leave many stratigraphic problems to be resolved through the study of additional highand mid-latitude sections.


This paper deals with the new role that firms at the second and third tier of the automotive supply chain are called to play in the ongoing process of globalisation of the automotive industry. It argues that the new demands these firms have to meet in product quality, service, and cost reduction imply a rationalisation of the lower tiers of the supply chain, which entails both selection among these firms and the upgrading of the survivors' competencies and performances. Most survivors will, however, be incapable alone of implementing the training and the long learning processes, which are needed to achieve this aim. Therefore the question of who should take care of such improvements (as regards their objectives, organisation, and costs) appears to be critical, and calls for original solutions. As a practical example of how to address its solution, we describe and comment on the program which Fiat Auto and about 100 of its direct suppliers have recently promoted in order to improve product quality at the second tier of this supply chain.


The parametric grid capability of the Knowledge Base provides an efficient, robust way to store and access interpolatable information which is needed to monitor the Comprehensive Nuclear Test Ban Treaty. To meet both the accuracy and performance requirements of operational monitoring systems, we use a new approach which combines the error estimation of kriging with the speed and robustness of Natural Neighbor Interpolation (NNI). The method involves three basic steps: data preparation (DP), data storage (DS), and data access (DA). The goal of data preparation is to process a set of raw data points to produce a sufficient basis for accurate NNI of value and error estimates in the Data Access step. This basis includes a set of nodes and their connectedness, collectively known as a tessellation, and the corresponding values and errors that map to each node, which we call surfaces. In many cases, the raw data point distribution is not sufficiently dense to guarantee accurate error estimates from the NNI, so the original data set must be densified using a newly developed interpolation technique known as Modified Bayesian Kriging. Once appropriate kriging parameters have been determined by variogram analysis, the optimum basis for NNI is determined in amore » process we call mesh refinement, which involves iterative kriging, new node insertion, and Delauny triangle smoothing. The process terminates when an NNI basis has been calculated which will fit the kriged values within a specified tolerance. In the data storage step, the tessellations and surfaces are stored in the Knowledge Base, currently in a binary flatfile format but perhaps in the future in a spatially-indexed database. Finally, in the data access step, a client application makes a request for an interpolated value, which triggers a data fetch from the Knowledge Base through the libKBI interface, a walking triangle search for the containing triangle, and finally the NNI interpolation.« less


This study quantifies the effects of weather conditions, irrigation, and plant age on yield and alpha-acids content of Czech hop cultivars Saaz, Sládek, Premiant and Agnus in a 25-year long period, i.e., from 1993 to 2018. The yields of Czech hop cultivars were increasing for the first three years of plant age until they stabilized and then started to decline slightly for 15 to 20 years until they reached the optimal time for replanting. The highest alpha-acids content in hop cones was achieved in the first year of cultivation, followed by a logarithmic decline in the upcoming years. Rainfall was the most significant factor that positively influenced the yield of Saaz hops with correlations of r = 0.59 and 0.61 (P < 0.01) for total seasonal rainfall (April–August), 0.65 (P < 0.001) and 0.60 (P < 0.01) for daily rainfall above 3 mm, 0.37 (P < 0.05) and 0.58 (P < 0.01) for rainfall in May and 0.50 (P < 0.01) and 0.32 (P < 0.05) in July in the Saaz region and the Stekník farm, respectively. The yield of cultivars Sládek, Premiant and Agnus was not statistically influenced by the amount of precipitation, but there was a positive effect of irrigation level on yield increase with correlations 0.58 (P < 0.01), 0.55 and 0.49 (P < 0.05), respectively. High air temperatures during summer were the most significant factor that negatively influenced the alpha-acids content with the correlations ranging from –0.56 to –0.83. However, cv. Agnus showed a stable weather-independent alpha-acids content.


Elders do not lose citizenship just because they get old, and a just society structures itself and its services in ways that keep elders engaged as full citizens. This is the central idea that Malcolm Payne conceptualizes as "citizenship social work with older people" in his book of the same name. Citizenship social work remains an intriguing but underdeveloped concept in this book, but gerontological social workers and students will find much of benefit in these pages. Payne is based in Britain and Poland, and his examples and assumptions reflect his European location, but the concepts explored in the book are worthy of consideration by US audiences, as well. This book has several strengths. Payne ends subchapters with implications for practice and policy, and this provides a clear and consistent focus on both the individual client and all the interlocking systems that influence the experiences of elders. Payne's "What's up?/Can do" framework is especially helpful here, where practitioners are encouraged to look beyond the narrative of a problem to anticipate elders' unmet needs and to remain committed past typical bureaucratic objections of the That's-not-my-department variety. The section on age-proofing and mainstreaming, focusing on practical steps to help elders remain engaged citizens, is especially useful to bring to life central concepts and support them with useful examples and case studies. Payne provides a remarkably strong explanation of the British concept of social care and makes a compelling argument for why framing social work as rooted in interpersonal caring is best. Social care is usually treated as a mere linguistic difference from social work, and Payne offers a pithy yet robust argument that this difference has philosophical and practical import. However, several limitations are extant in the book, as well. Payne has a tendency to assert, rather than demonstrate, the value added by alternative perspectives, and he introduces many perspectives that become confusing, given how weakly conceptualized citizenship social work is. Payne maintains that elders have both the right and the responsibility to remain engaged in society, and society has the responsibility to make sure that elder engagement is possible and supported. By framing continued engagement as a duty and not merely an option for elders, Payne offers some welcome pushback against implicit assumptions that self-isolation is a legitimate choice


This study investigates the labour supply structure of immigrant women in Australia using the 1990 Survey of Income, Housing Costs and Amenities. It is deduced that immigrant women from non-English-speaking backgrounds (NESB) have a lower probability of being employed but, among the sub-sample of employed women, they work more hours per year than Australian-born women or immigrant women from English-speaking backgrounds (ESB). This study indicates that legislation at the time of the Howard government, causing immigrants to be ineligible for government benefits for the first two years of settlement in Australia, may have moderately increased the utilisation of human capital of immigrant women from non-English-speaking backgrounds.


Abstract : Recent discovery of the delay/Doppler technique (Raney, 1996) opens new opportunities for radar altimetry. This new technique promises relatively fine spatial resolution, greater precision, substantially improved tracking and measurement accuracy near coastlines and surface feature contrasts, and reduced on-board power requirements. These attributes should translate into better performance from a smaller, less expensive instrument, a prediction that as of now is untested. The main thrust of this and related projects is to respond to that challenge: demonstrate that the delay/Doppler altimeter is a compelling candidate for an advanced instrument that would meet the requirements of future satellite radar altimeter missions.


It is predicted that globular clusters are likely to contain a new class of magnetic cataclysmic variables (CVs) with significantly high fields which is unknown among the CVs in the solar neighborhood. In addition, estimates of their expected X-ray luminosities are made and it is proposed that X-ray surveys combined with optical/UV observations should lead to the detection of the brightest of them. Specific target globular clusters with high probability of detection of these sources are given. 26 refs.


The Copyright Clearance Center (CCC) was created to facilitate compliance with US copyright law. It serves both foreign and domestic copyright owners and the users of their work. Over the past ten years CCC has developed its major services. The Annual Authorizations Service (AAS) provides annual blanket licences to permit major companies to photocopy copyright material. Various statistical sampling methods are used to establish the level of use and thus the cost of the licences. In 1986 700,000 photocopies were made under this scheme. The Transactional Reporting Service (TRS) is the original scheme whereby users voluntarily report and pay copying fees for CCC‐registered publications on a per‐copy basis. At present some 2,400 users have established accounts with CCC under this scheme: approximately 3.3 million photocopies have been reported through the service since its inception in 1978, 600,000 of these in 1986. Despite the growing popularity of the AAS, this service is still showing a pattern of consist...


Objectives The aim of this study was to study the blood level of matrix metalloproteinase-9 (MMP-9) in acne patients and its relation to disease severity. Background The possible use of MMP-9 as a biomarker of acne severity. Patients and methods This case–control study was conducted on 45 patients with acne vulgaris collected from the Dermatology Outpatient Clinic in Menoufia University Hospital with age ranging from 18 to 25 years. The study was done during the period from June 2018 to January 2019. Acne grading was performed according to the Global Acne Grading System. Twenty normal controls matched for age and sex were included. Detailed history and clinical exa mination were carried out to exclude patients with hyperproliferative skin disorders such as psoriasis and lichen planus, patients with bullous diseases, therapy. MMP-9 was measured by the enzyme-linked immunosorbent assay method for patients and controls and the results were statistically analyzed and tabulated. Results The level of MMP-9 recorded significant elevation when compared with normal control level. In addition, a significant difference was obtained when comparing its level among mild, moderate, and severe cases. There was also an association between its level and the number of regions with inflammatory pustules and nodules but not with scars. Conclusion MMP-9 can be used in the future as a biomarker of acne severity to choose the best treatment modalities.


The Wunugetu mountain copper deposit is located at northwest of deerbugan ore belt.Copper,molybdenum,lead and zinc constitute the main ore-forming elements.Further prospecting orientation in the zone was proposed based on the summary of geological character and characteristics and ore controlling regularities of the deposit.


iological diversity is essential, whether for agricultural and forestry systems, pharmaceutical products, aesthetics, tourist income, evolutionary processes, stabilization of ecosystems, biological investigations, protection of overall environmental quality, or intrinsic worth of all species on Earth (Ehrlich and Wilson 1991, Wilson 1988a). Although approximately 90% of world food for people comes from just 15 plant species and 8 animal species (Wilson 1988a), several thousand other plant species are used as food by humans (Altieri et al. 1987a). Furthermore, both high agricultural productivity and human health depend on the activity of a diverse natural biota composed of an estimated 10 million (range 2-80 million) species of plants and animals that inhabit the world (Wilson 1988b). The United States is home for an estimated 500,000 species, of which small organisms, such as arthropods and microbes, comprise 95% (Knutson 1989). As many as 1 million species of plants and animals will be exterminated worldwide dur-


We aim at developing an intelligent robotic platform that provides cognitive assistance and natural support in indoor environments to the elderly society and to individuals with moderate to mild walking impairment. Towards this end, we process data from audiovisual sensors and laser range scanners, acquired in experiments with patients in real life scenarios. We present the main concepts of an automatic system for user intent and action recognition that will integrate multiple modalities. We demonstrate promising preliminary results, firstly on action recognition based on the visual modality, i.e. color and depth cues, and secondly on the detection of gait cycle patterns that exploit the laser range data. For action recognition we are based on local interest points, 3D Gabor filters and dominant energy analysis, feeding a support vector machine. Then the recognized actions can trigger the gait cycle detection that detect walking patterns by exploiting the laser range data, modeled by hidden Markov models. In this way, we shall acquire the overall patient's state and the robot shall autonomously reason on how to provide support.


We present an approach to learning Robocode controller strategy. Robocode strategies are represented as trees of atomic elements corresponding to actions and observations in a Robocode battle. Genetic programming is used to search the space of such representations. Through this approach, we were able to induce stategies capable of defeating many hand-coded tanks.

It is required to have researches on efficient resource allocation schemes in an integrated voice and data CDMA system with the spreading of high-speed wireless internets. In this paper, we proposed a efficient resouce allocation scheme for providing a high speed data service in an integrated CDMA system. In an integrated voice/data CDMA system, resources for voice users are allocated with high priority and residual resources are allocated to the data service. In this case, it is necessary to use a resource allocation scheme for minimizing interference. In this paper, we first explain about a interference minimizing method and define QoS requirements. Based on the method, we proposed a efficient resource allocation scheme which satisfy the QoS requirements. The proposed scheme controls the transmission rate and delay of data users with a priority information such as the number of packets in a queue. From the simulation results, we show that the proposed scheme reduce the blocking probability and delay and improve the performance.


The flash‐photolysis resonance‐fluorescence technique has been employed to measure the rate constant for O+SiH4→products from 295–565 K, and yielded k1=1.23×10−10 exp(−14.6 kJ mol−1/RT) cm3 s−1 with an accuracy of about ±15%. The transition state for direct H‐atom abstraction has been characterized at up to the Gaussian‐2 ab initio level of theory. With small adjustments it is possible to model kinetic data for O+SiH4 in terms of an abstraction channel leading to OH+SiH3. This agreement does not rule out minor participation by addition or insertion channels, but there is no theoretical evidence for bound triplet intermediates in the potential energy surface. A transition state theory analysis suggests that k1 at 1000 K is 16 times larger than previously thought.

This work reveals the functional divergence of the three CUP-SHAPED COTYLEDON genes during Arabidopsis leaf development. In particular, it shows that the functions and expression patterns of CUC1 and CUC2 diverged since the formation of these genes by the duplication of a common ancestor within the Brassicale lineage. CUP-SHAPED COTYLEDON2 (CUC2) and the interacting microRNA miR164 regulate leaf margin dissection. Here, we further investigate the evolution and the specific roles of the CUC1 to CUC3 genes during Arabidopsis thaliana leaf serration. We show that CUC2 is essential for dissecting the leaves of a wide range of lobed/serrated Arabidopsis lines. Inactivation of CUC3 leads to a partial suppression of the serrations, indicating a role for this gene in leaf shaping. Morphometric analysis of leaf development and genetic analysis provide evidence for different temporal contributions of CUC2 and CUC3. Chimeric constructs mixing CUC regulatory sequences with different coding sequences reveal both redundant and specific roles for the three CUC genes that could be traced back to changes in their expression pattern or protein activity. In particular, we show that CUC1 triggers the formation of leaflets when ectopically expressed instead of CUC2 in the developing leaves. These divergent fates of the CUC1 and CUC2 genes after their formation by the duplication of a common ancestor is consistent with the signature of positive selection detected on the ancestral branch to CUC1. Combining experimental observations with the retraced origin of the CUC genes in the Brassicales, we propose an evolutionary scenario for the CUC genes.


The fiber optic gyroscope (FOG) is a solid-state rotation sensor which is currently employed in inertial navigation systems. Highly birefringence fibers can be used to as polarization-maintaining (PM) fiber in FOG. PM fibers can reduce both the drift polarization cross coupling created polarizer and drift due to the earth's magnetic field via the Faraday Effect. But when the two beams polarized along fast and slow axes traverse the PM fiber, interference between the two counter-propagating beams may be influenced by the dispersive nature of the modal birefringence. The modulus of the degree of coherence, |γ| with respect to the interference between the two orthogonally polarized waves, may impose a severe restriction on the phase difference detection. Hence the problem of the signal to noise radio with respect to the received signal may be strongly influenced by the modulus of the degree of coherence. In this paper interference between two orthogonally polarized modes traversing a highly birefringence fiber is investigated theoretically and experimentally. Simulation results show that the detection sensitivity of fiber optic gyroscope employing highly birefringence fiber is degraded as the chromatic dispersion difference between the two mode increases. The result obtained here will provide useful data for the design and performance evaluation of fiber-optic sensors employing polarization-maintaining fibers.

Person recognition using ear biometric has received significant interest in recent years due to its highly
discriminative nature, permanence over time, non-intrusiveness, and easy acquisition process. However, in a realworld
scenario, ear image is often partially or fully occluded by hair, earrings, headphones, scarf, and other objects.
Moreover, such occlusions may occur during identification process resulting in a dramatic decline of the
recognition performance. Therefore, a reliable ear recognition system should be equipped with an automated
detection of the presence of occlusions in order to avoid miss-classifications. In this paper, we proposed an efficient
ear recognition approach, which is capable of detecting the presence of occlusions and recognizing partial ear
samples by adaptively selecting appropriate features indices. The proposed method has been evaluated on a large
publicly available database containing wide variations of real occlusions. The experimental results confirm that
the prior detection of occlusion and the novel selection procedure for feature indices significantly improve the
biometric system recognition accuracy.


In storage systems, delta compression is often used as a complementary data reduction technique for data deduplication because it is able to eliminate redundancy among the non-duplicate but highly similar chunks. Currently, what we call 'N-transform Super-Feature' (N-transform SF) is the most popular and widely used approach to computing data similarity for detecting delta compression candidates. But our observations suggest that the N-transform SF is compute-intensive: it needs to linearly transform each Rabin fingerprint of the data chunks N times to obtain N features, and can be simplified by exploiting the fine-grained feature locality existing among highly similar chunks to eliminate time-consuming linear transformations. Therefore, we propose Finesse, a fine-grained feature-locality-based fast resemblance detection approach that divides each chunk into several fixed-sized subchunks, computes features from these subchunks individually, and then groups the features into super-features. Experimental results show that, compared with the state-of-the-art N-transform SF approach, Finesse accelerates the similarity computation for resemblance detection by 3.2×∼3.5× and increases the final throughput of a deduplicated and delta compressed prototype system by 41%∼85%, while achieving comparable compression ratios.


Objective: To investigate the fetal thyroid function using ultrasound imaging combined with amniotic fluid hormone concentration. Method: 380 pregnant women who did pregnancy test in our hospital from August 2015 to August 2017 were selected as the subjects. 260 of them
 had normal fetal growth indicators, all of them were singletons, with a gestational time of 18–41 weeks. 120 pregnant women underwent cesarean section, parturition, and amniocentesis. All pregnant women had no thyroid related diseases, hypertension, or autoimmune diseases. 3DUS (Three-dimensional
 ultrasound) and 2DUS (two-dimensional ultrasound) were used to measure the size of fetal thyroid gland, and the amniotic hormone content was measured. Result: The repeatability and consistency of the 3DUS-VOCAL (Voual organ computerized analysis) technique were superior to 2DUS in the
 measurement of fetal thyroid volume in 20 cases. There were 243 fetal thyroid size-related data collected from 260 fetuses at 18 weeks and 41 weeks of pregnancy. Amniotic fluid FT3, T3 had a certain correlation with gestational age, but amniotic fluid FT4, T4, TSH had no significant correlation
 with gestational age. 4 cases of fetal hypothyroidism were screened by ultrasound combined with amniotic fluid hormone measurement. Conclusion: The volume of fetal thyroid measured by 3DUS-VOCAL is better than that of 2DUS. Ultrasound combined with amniotic fluid thyroid associated
 hormone detection is helpful to evaluate fetal thyroid function.


Eurasian badgers, Meles meles (L., 1758), have an extensive geographic range throughout which their social organization varies. Their capacity for intraspecific variation can now best be understood by studying them in landscapes that differ from the lush, lowland farmland where their tendency to form large groups has been most intensively investigated. Badgers in cork oak (Quercus suber L.) woodland are thus a priority for study, as this Mediterranean landscape provides an extreme contrast to those studied elsewhere. In this habitat in Portugal, we found 0.36–0.48 badgers/km2, one of the lowest population densities recorded in Western Europe. Here, individuals used seasonally stable home ranges that averaged 4.46 km2 and that were occupied by 3–4 adults plus 3–4 cubs of the year. In this landscape, badgers selectively used cork oak woodland with understory and riparian vegetation. As predicted by the resource dispersion hypothesis, home-range size was positively correlated with food-patch dispersion. In s...


Effects of RE-Mg modification on carbide morphology,distribution and mechanical properties of high chromium cast iron for roller were investigated.The results show that adding appropriate RE-Mg in high chromium cast iron can obviously refine the microstructure and improve the morphology and distribution of carbides;after modification,carbide from the sharp edges of the strip changes into isolated crumb or ball,and separating degree on the matrix is greatly reduced.The comprehensive mechanical properties are the best when adding RE-Mg is 0.6wt%.


The use of anticoagulants to reduce thromboembolic complications following myocardial infarction and to prevent coronary thrombosis in patients with angina is the subject of sharp controversy. Many eminent clinicians are convinced that anticoagulant therapy during the six weeks or so of the acute phase of infarction saves many lives by reducing the risk of venous and mural thrombosis, embolism and new myocardial infarctions; some of them believe that mortality from coronary artery disease can be further reduced by giving anticoagulants for life after infarction or in patients with severe angina. Some favour anticoagulant therapy only in "high risk" patients, that is, those with severe infarction, heart failure or serious arrhythmias. Other clinicians, equally eminent, find no justification for the routine use of anticoagulants during either the acute phase of myocardial infarction or subsequently.


A novel approach to thermo- and magnetoresponsive drug delivery is presented, using magnetic nanoparticles decorated with a β-cyclodextrin (β -CD) containing polymer brush shell. The iron oxide based magnetic cores with a diameter of 10-12 nm can be used for remote controlled magnetic heating by AC fields. The polymer shell is created by atom transfer radical copolymerization of 2-(2-methoxyethoxy)ethyl methacrylate (MEEMA), oligo(ethylene glycol) methyl ether methacrylate (OEGMA) and the β -CD functional monomer 3-(6-desoxy)-β-cyclodextrin-3H-1,2,3-triazol-4-yl) methylmethacrylate (CDMA). The β-CD units are responsible for a thermosensitive complex formation equilibrium with hydrophobic probes, demonstrated here for the case of phenolphthalein as a model substance. The probe release induced by magnetic heating is greatly enhanced at the lower critical solution temperature (LCST) of the polymer shell. In this work the synthesis and complex formation behavior of the β-CD functional magnetic carriers is investigated with respect to the thermally and magnetically influenced drug release.


_________________________________________________________________________________ Introduction: It is a known fact that traditional practices mothers use in increasing breast milk supply and weaning differ in different parts of countries and even among communities sharing the same city. This study was conducted to find out the use of herbal tea and some foods to increase breast milk, the traditional methods used for weaning and the factors influencing these. Materials and methods: This study is descriptive and cross-sectional. Three cities in Turkey with different levels of development in terms of geographical and socio economic regions were chosen. The data of the study were collected through a questionnaire form developed by the researchers. Results: It was found that the mothers who received breast milk increasing training the most were in eastern region, while mothers in western region fed their babies with formula since they thought their milk was not enough and this result was found to be statistically significant (p<0.05). In our study, it was found that 42.1% of the mothers resorted to some plants and foods to increase breast milk. When the mothers were asked about how they weaned their babies, it was found that 38.2% pasted things like hair and wool or put tomato paste on the breast, 26.9% applied bitter food on the nipple while 27.7% stated that the babies stopped breastfeeding spontaneously. Conclusion: It was found that mothers resorted to traditional methods to increase breast milk and to wean and that there were regional differences.


Pt‐Sn‐Eu catalysts were synthesized by modified polyol method, evaluated for the ethanol oxidation reaction (EOR), and compared to commercial Pt/C and Pt‐Sn/C catalysts. The catalysts were electrochemically characterized in both three‐electrode and fuel cell setups. X‐ray diffraction measurements indicated some degree of Pt‐Sn alloying in the Pt‐Sn‐Eu/C catalysts, and mean crystallite sizes between 2.3–3.3 nm, while X‐ray photoelectron spectroscopy measurements showed the presence of Pt and Sn in both metallic and oxide form, and rare earth metals in the form of mixed oxides. Adding tin and europium promoted filling of the Pt 5d band, as confirmed by X‐ray absorption. The electrochemical characterization showed a higher oxidation current density and lower oxidation onset potential for the ternary Pt‐Sn‐Eu materials compared with the commercial catalysts, in both the three‐cell and fuel cell tests. High performance liquid chromatography measurements indicating that the main products of ethanol oxidation were acetaldehyde and acetic acid; a low concentration of CO2 was also detected. The improved ethanol oxidation efficiency for the Pt‐Sn‐Eu/C catalysts can be explained by the Sn/Eu‐Pt electronic effect, because it weakens the adsorption of intermediate products by Pt, and favors the bifunctional EOR mechanism, as europium oxide renders oxygenated species available at lower potentials.


This paper studies the pathwise asymptotic stability and integrability of the zero solution of a finite dimensional Ito-Volterra equation. Under Lipschitz conditions on the state-dependent functions, and with continuity and integrability required of the kernels, it is shown that any solution which is p-th mean integrable for some p ≥ 2 is p-th mean-asymptotically stable, and also p-th mean integrable and asymptotically stable, almost surely. If there is no delay-dependent term in the volatility, the same result can be shown for p ≥ 1. Examples which illustrate the usefulness of these results are presented, and extensions to other classes of functional differential equations discussed.

The principal contributors to variations in the ultraviolet environment of Mars are ozone and dust. Ozone is a strong absorber of ultraviolet (UV) light, resulting in a reduction in transmitted radiance in the wavelength region surrounding 255 nm. The spatio-temporal distribution of ozone may be investigated by comparing spectral observations from Mars orbit with solar reference spectra. The photoionisation of molecular species in the upper atmosphere is driven by high energy solar UV radiation, therefore the photochemical role of ozone is a prominent component of the complex system of chemical reactions regulating the atmospheric system. The effect of dust on observed radiance from orbit is a factor in the accuracy of ozone abundance retrievals, particularly at high solar zenith angles (decreased radiance and increased scattering) or high dust loading conditions. The aim of this work is to apply varying dust aerosol distributions, concentrations, and properties to a library of ozone vertical profiles (with consistent atmospheric structures) in order to quantify the effect of dust on future ozone abundance retrievals.


There are still huge challenges in the development of carbon dots (CDs) based long afterglow materials with multicolor emissions, especially in aqueous solutions. This work reports a novel strategy of achieving of multicolor long afterglow in aqueous solution by incorporating phosphorescent CDs and fluorescent dyes into sub‐20 nm monodispersed silica nanoparticles. The silica matrix not only stabilizes the triplet excitons of CDs but also facilitates the efficient cascade Förster resonance energy transfer between the phosphorescent donor (CDs) and the energy acceptor (fluorescent dyes), which enables intensive multicolor long afterglow with adjustable wavelength from 510 to 610 nm and the largest Stokes shift of 255 nm. Based on these multicolor long afterglow nanoparticles, some time‐resolved, color multiple information encryptions are designed. By eliminating background noise, the signal‐to‐noise ratio of in vivo afterglow imaging is as high as 155.1 in the in vivo imaging system. Interestingly, the afterglow signal in mice can be easily and conveniently collected by the camera of cell phones, which may make in vivo bioimaging portable and inexpensive. This study will provide new ideas for the synthesis of multicolor CDs‐based long afterglow materials in solutions.


Attention to financial literacy has grown in recent years, in large part because technological, market, and legislative changes have resulted in a more complex financial services industry that requires consumers to be more actively involved in managing their finances. Consumer and community interest groups, banking companies, government agencies, and policymakers, among others, have become concerned that many consumers lack a working knowledge of financial concepts and the tools they need to make decisions most advantageous to their economic well-being. As a result, considerable resources have been devoted to financial literacy, with a wide range of organizations providing training, including banks, consumer and community groups, employers, and government agencies. Overall, studies suggest that financial literacy training can lead to better decisionmaking; however, the findings raise numerous questions about the best means of providing that training, the most appropriate setting, and the most opportune timing. Findings from recent research on personal money management styles, combined with awareness of human behavioral traits, offer insights that may be useful in developing successful training programs and strategies.


The development of highly efficient and rapid photoinitiating systems for free radical photopolymerization under the irradiation of visible light has attracted increasing attention due to their widespread potential applications in, for example, 3D printing or dental polymers. Unfortunately, currently available visible-light-sensitive photoinitiators are not efficient enough for 3D printing applications suffering from low printing speeds. Here we describe a series of photoinitiating systems consisting of disubstituted aminoanthraquinone derivatives (i.e., 1-amino-4-hydroxyanthraquinone, 1,4-diaminoanthraquinone, and 1,5-diaminoanthraquinone) and various additives (e.g., tertiary amine and phenacyl bromide) toward the free radical photopolymerization of various acrylate monomers (such as commercial 3D resin) under the irradiation of blue to red LEDs. It is shown that the type and position of substituents of the aminoanthraquinone derivative can significantly affect its photoinitiation properties. The most e...


LinkedIn is the largest professional networking application in the world, classified as a social networking site (SNS) application. Indonesia is one of the countries with the highest number of active LinkedIn users. To ensure user comfort, LinkedIn regularly updates their application. However, recently there have been some negative ratings regarding the LinkedIn application. To directly assess this, a research study was conducted to determine user satisfaction while interacting with the features available on LinkedIn. This research was carried out using the user experience questionnaire method, with 35 respondents participating. This method consists of 26 questions representing six assessment indicators, including attractiveness, efficiency, perspicuity, dependability, stimulation, and novelty. The indicator with the highest score is stimulation, with a score of 1.48, which is categorized as good. On the other hand, the lowest indicator score is perspicuity, which only obtained a score of 0.79, below average. Overall, LinkedIn has received predominantly positive feedback. However, it is still recommended to continue innovating, especially focusing on improving perspicuity aspects that are tailored to the needs and issues faced by users.


This paper presents a fully protected high side switch design from the short circuit perspective. The high side switch is dual configurable: either 7 Ω or 2 Ω in terms of ON resistance, each with its short circuit current limitation level. The circuit was implemented in a BCD technology, where the key for area efficiency is making use as much as possible of the low voltage components. This is especially difficult for high side switch design, where the circuit is referred to the high voltage car battery.

This paper focuses on the interpretation of Xinleishendong presented at "Lin Hui-yun Graduate Concert". The Xinleishendong is one of classical plays in beiguan new style theatre music. The script of Xinleishendong used at the concert was passed down by beiguan master Lin Sui-chin (hereinafter Lin's version). This paper begins with story research and scripts comparison of Xinleishendong, followed by interpretation and discussion on the version which the author learned from master Lin Sui-chin. On the comparison of the text of this play, the author compared four versions of scripts: Qing Menggu Chewangfu Changquben, the script collected in the Lihuayuanluozidi Xiange Chang-hua Lichunyuan Lishiluyin, and the scripts of beiguan master Yeh Mei-ching's version and Lin's version. Among the four versions of scripts, Lin's version primarily utilize beiguan melodic patterns of jī-hong and se-phi, along with other beiguan melodic patterns of to-tsu, tiap-pan, and hue-khang (hue-khiang). The setting of melodic patterns displays colorful beiguan music in its characteristic appearance. Chapters two and three analyze and discuss the characteristics of melodic patterns, vocal projection, setting of percussion ensemble music, and interpretation of master Lin's version in detail.


Three models of sound propagating into and within a water‐saturated sandy bottom are compared to measurements made in the NRL shallow water laboratories. An initial set of measurements was made in a manufactured 212‐μm mean diameter sand, which was washed and filtered, to quantify sound penetration as a function of incident angle and interface roughness, as well as to identify the wave types generated within a water‐saturated sandy bottom. Measurements have also been made of sound propagation within a water‐saturated sandy bottom, which employed a specialized set of transducers to generate and measure compressional waves and a second set of transducers to generate and measure shear waves. Measurements have also been made in a 525‐μm mean diameter water‐saturated sand. All of the above measurements are compared to a fluid bottom model and a Biot media model, both of which characterize the sound propagating within a water‐saturated sandy bottom. In addition, the measurements of sound penetration into the standy bottom are compared to roughened interface scattering models. [Work supported by NRL and ONR.]


Like other academicians, MIS researchers have boundary-less careers that rely more on personal drive than affiliated institution to develop career competencies and achieve career success. Unlike other fields, maintaining career success in the MIS academic community requires frequent update to the research themes to maintain relevance to the professional and academic community. As such, adapting expertise and building social relationships is instrumental for career success. In this study, we explore how faculty who "know why", "know how" and "know with whom" are successful in advancing their careers; while faculty who do not master these three competencies have limited success and impose social closure on themselves and are incapable of exploiting resources to their advantage. Based on the findings, we advance a number of theoretical propositions to guide future research on the effect of the three types of knowing on academic careers.


The fiber cross-sectional parameters are difficult to be extracted accurately due to pressing when the fiber was embedded and cut by the traditional technologies.Proper colophony used to embedded fibers can keep the shape of fiber cross-sections better.The influences of different embedded technologies on the single hollow fiber(hollow polyester fiber and kapok fiber) cross-sectional parameters were researched.The results show that the suitable colophony can reduce the extent of deformation of fiber cross-section apparently,especially for the hollow and thin-walled fiber,such as kapok fiber.


Two recent studies published in "Perspektiven der Wirtschaftspolitik" are used to discuss methods to develop bibliometric analyses and rankings of economic research institutions. According to them, standardisation methods using the number of staff or university graduates may have a crucial impact on results, especially when the weighting methods used are not sufficiently selective. Different methods to prepare the database also have considerable influence on the data quality and results. Rankings based on a variety of methods for weighting the quality are frequently highly correlated with each other, but they supply quite different placements for institutes.

The subject of this paperis a two-stage hypothesis test, which may have interesting applications in several situations related to the opinion research field. Such test is based on the components of a Bivariate Correlated Normal random variable. In particular, it is based on the exact distribution of their minimum and maximum modulus. This test was proposed for the first time by Duncan in Miller (1981), and was recently improved by Pollastri (2008). In the latter paper a variant of such test is described, since two samples in two different times or situations are considered. Two kinds of applications are provided to show the wide range of usage.


Seeking an optimum sustainable development strategy is a core objective of municipalities and innovative urban planners around the world. Various viewpoints and interests regarding the interface between ports and cities and the resulting extensive waterfront regeneration in principal seaports render spatial planning projects of this type complex to complete and obtain agreement on. For a modern city, port development is a principal source of influences and benefits related to ecology, society, and transportation. Currently, the world's largest seaports are moving cargo terminals out of historical city centres. As a result, ports are assuming more advanced functions unrelated to the maritime industry, and thus projects that equitably share port territories will naturally gain momentum. The most significant projects for moving cargo ports out of historical town centres and regenerating port areas are found in European cities. To understand the various approaches, examples from European regeneration projects for port territories in Bilbao, Barcelona, and Oslo are presented, and their experience with various geographical and town-planning conditions is highlighted. This study is devoted to the Ukrainian port city of Odesa. It identifies the most successful strategy for developing the port-city interface under current economic and geopolitical conditions. It combines the ideas and studies of city planners in management, economics, and transport geography along with various policies and sociology aspects to provide new information and understanding aimed at ensuring the sustainable development of coastal cities in developing countries.


Game theory, the study of strategies and decision making, is represented in the Medical Subject Headings (MeSH) vocabulary by two terms---GAME THEORY and its immediately narrower term, GAMES, EXPERIMENTAL. Both are terms in MATHEMATICS---a branch of the NATURAL SCIENCES (MeSH Tree H01). Contextual co-descriptor analysis was used to explore and visualize the game theory topics relevant to medical researchers and scholars, based on the frequently-assigned MeSH terms assigned to articles also indexed with one or another of these two MeSH terms. The literature indexed with GAME THEORY deals primarily with two key concepts in the field---Evolutionary Game Theory and Human Behavior. GAMES, EXPERIMENTAL retrieves several very different topics---general game-theoretic behavioral research, human cognition and neuroimaging, and nursing education. It appears that the assignment of GAMES, EXPERIMENTAL conflates the notions of (1) experiments in Game Theory (testing decision-making scenarios), (2) modeling human brain processes during decision making, and (3) the use of a variety of different kinds of games and simulations to teach in nursing programs. The last might be considered a poor fit to the notion of the role of games in Game Theory as it is generally understood by game theorists.


AN APPROXIMATE METHOD IS PROPOSED FOR EVALUATING THE STABILITY OF A ROCK SLOPE SUBJECTED TO EXTERNAL FORCES. THE STRENGTH OF ROCK IS CHARACTERIZED BY THE ANGLE OF FRICTION AND THE COHESION OF THE DIFFERENT FRAGMENTATION SYSTEMS. THE MODULUS OF ELASTICITY OF THE ROCK NEED NOT BE KNOWN. A NUMERICAL EXAMPLE ILLUSTRATES THE METHOD WHICH WAS DEVELOPED DURING FOUNDATION WORKS OF THE LEMAN MOTORWAYS. /TRRL/


The objectives were to provide a low cost, air cooled and robust laser. Nd:YVO/sub 4/ crystal is now a current choice as a lasing material for diode-pumped solid state laser because of its high gain, high absorption and also linearly polarized output. However its poor thermal properties and its fragility, compared to Nd:YAG, are disadvantages for industrial applications. Composite crystals with adhesive free bonding are good solutions to reduce thermal lensing and improve crystal robustness. Results obtained with a segmented Nd:YVO/sub 4/ crystals manufactured by FEE with a new technology bonding are presented and the advantages of this technology will be discussed.

Recent advances in diffusion models have showcased promising results in the text-to-video (T2V) synthesis task. However, as these T2V models solely employ text as the guidance, they tend to struggle in modeling detailed temporal dynamics. In this paper, we introduce a novel T2V framework that additionally employ audio signals to control the temporal dynamics, empowering an off-the-shelf T2I diffusion to generate audio-aligned videos. We propose audio-based regional editing and signal smoothing to strike a good balance between the two contradicting desiderata of video synthesis, i.e., temporal flexibility and coherence. We empirically demonstrate the effectiveness of our method through experiments, and further present practical applications for contents creation.


The strength of hydrogen bridge bonds in rows of anthraquinone (AQ) and 9,10-dithioanthracene (DTA) molecules adsorbed at a Cu(111) surface is investigated by means of scanning tunneling microscopy. The temperature-dependent rate of abstraction of molecules from the molecular rows was measured. Evaluation of the results similar to molecular diffusion data indicates an abstraction barrier of 0.13 and 0.16 eV for AQ and DTA, respectively. Given known diffusion barriers, this offers an estimated energy of the O···H−C and S···H−C hydrogen bond of 0.05 and 0.02 eV for AQ and DTA, respectively.

One of the reasons for the low numeracy skills in elementary schools is the lack of application of instructional media which provides opportunities for students to practice directly and train themselves to be skilled at counting. To improve students' numeracy skills, learning innovations are needed that involve students actively through direct learning experiences. One alternative solution to this problem is to use colored beads as learning media in learning Mathematics in Elementary Schools. This study aims to find out 1) to know the application of color bead media to grade 1 elementary school mathematics 2) to find out the increase in math skills in grade 1 elementary school students after using color bead media, and 3) to know the effect of using the media the color of the beads on the numeracy skills of 1st grade students. This research is a systematic literature study. Based on this discussion, the media of colored beads is very effective for improving students' numeracy skills, because students have the opportunity to directly practice and train themselves to be skilled at counting. The results of the research are expected to provide an overview for developing further research regarding improving numeracy skills through learning media of colored beads in mathematics in elementary schools.


A synthetic assessment of the equipping of Poland's voivodships with road and railway infrastructure was conducted to identify needs, as well as future action to be taken as regards infrastructure development. Reference was made to two main approaches to assessment: one providing econometric estimates of infrastructure productivity, where transport infrastructure equals public capital in production functions; and the other analyzing changes in regional road and rail accessibility. This paper in fact presents an indicator incorporating both the quantity and the quality of road and rail infrastructure, with two widely-used density indicators relating to population and area being applied. A third indicator including both population and area was also taken into account. A comparison of Poland's voivodships was made on the basis of the results. Particular attention has been paid to operational work on the state road network and train operations. Traffic intensity was found to vary markedly between voivodships, and this should be the main reason to improve the degree to which given areas are equipped with road and rail infrastructure. It is concluded overall that the shares of operational work regions account for correlate strongly with the shares of GDP they take. Priority should thus be given to investment in voivodships displaying the highest level of operational work, in particular centrally-located regions. The second goal of the investment policy should be attained via investments in the regions of highest GDP growth, because operational work is probably going to be higher there as well. Eventually, infrastructure should also be improved in regions where the needs as regards operational work are less urgent, e.g. in south-eastern Poland – an area that unfortunately suffers from poor transport infrastructure. The conclusion is nevertheless that asymmetrical investments leading to greater differences in equipping with infrastructure from region to region do represent the best solution for Poland at this time.


The design and performance of 180 GHz substrate integrated waveguide filters is presented. It is shown that photoimageable thick film technology can achieve the precise dimensional control needed for design at G-band. TRL calibration standards are fabricated in the substrate integrated waveguide medium itself and excellent results are obtained for the 140–200 GHz frequency range. 0.1 and 0.01dB ripple filters are designed and fabricated, with 8 and 6.2% relative bandwidths. The measured results show excellent agreement with electromagnetic simulations.

The present study aimed at identifying the system of religious values and its opposite, which included children's programs in the Space Toon TV channel in a sample of Saudi children (6-9 years). To achieve this goal has been to use the descriptive analytical method by designing standard for religious values and it's opposite form and content analysis and identification of students from 6-9 years. The study sample was (418) students. The study concluded that the number of the value system as it came through content analysis of children's programs (68) the value of sub-opposite result from the analysis (240) episode of the children's programs, were as follows: the number of religious values, subparagraph (41) value and a percentage (60%), while the antithesis of religious values amounted to (27) and that represents more than (40%), and results showed that the order of religious values and opposite from the most to at least is as follows: belief in God was (29.41%), lying was (27.94%), truthfulness was (13.24%), jealousy was (11.77%) ,humbleness was (7.35%), keeping the promises was(5.88%) and finally the devotion was (4.41%). The results showed that the system of religious values and opposite may have included students at different rates.


This paper looks at an alternative curriculum model for study abroad designed specifically to address some of the needs of non-traditional students enrolled in an online education program. In order to meet the needs of non-traditional students and provide quality international programming for them, it is necessary first to understand their restraints to studying abroad, and then to design alternative educational models that can address these challenges. The paper describes the challenges of balancing the need to create quality international learning opportunities for education students, with the limitations faced by non-traditional online adult learners who have families and full-time jobs. It is based on an action research case study of two study abroad programs implemented for online students at a northeastern four-year research-one institution of higher education.

We study exchange interaction between two magnetic impurities in doped gapped graphene (the Ruderman-Kittel-Kasuya-Yosida [RKKY]) interaction by directly computing Green's function beyond Dirac approximation. Tight binding model Hamiltonian in the presence of magnetic long range ordering has been applied to describe electron dynamics. RKKY interaction as a function of distance between localized moments has been analyzed. It has been shown that a magnetic ordering along the z-axis mediates two different interactions for spin directions which corresponds to a XXZ model interaction between two magnetic moments. The exchange interaction along arbitrary direction between two magnetic moments, has been obtained using the static spin susceptibilities of gapped graphene structure. The effects of spin polarization on the the dependence of exchange interaction on distance between moments are investigated via calculating correlation function of spin density operators. Our results show the chemical potential impacts ...


The efficiency and correctness of continuous Arabic Speech Recognition Systems (ARS) hinge on the accuracy of the language phoneme set. The main goal of this research is to recognize and transcribe Arabic phonemes using a data-driven approach. We used the Hidden Markov Toolkit (HTK) to develop a phoneme recognizer, carrying out several experiments with different parameters, such as varying number of Hidden Markov Model (HMM) states and Gaussian mixtures to model the Arabic phonemes and find the best configuration. We used a corpus consisting of about 4000 files, representing 5 recorded hours of Modern Standard Arabic (MSA) of TV-News. A statistical analysis for the phonemes length, frequency and mode was carried out, in order to determine the best number of states necessary to represent each phoneme. Phoneme recognition accuracy of 56.79% was reached without using a language model. The recognition accuracy increased to 96.3% upon using a bigram language model.


Haddad et al. pointed out the lack of odor metrics, i.e. rules describing olfactory perceptual space, as an obstacle to understand olfactory coding, and proposed two physicochemical metrics 2 . More recently, a descriptive analysis was performed of the FlavorBase 2010 (FB2010; http://www.leffingwell.com), putting forward that the odor description can be successfully analyzed using a metric approach 4 .


As human-machine voice interfaces provide easy access to increasingly intelligent machines, many state-of-theart automatic speech recognition (ASR) systems are proposed. However, commercial ASR systems usually have poor performance on domain-specific speech especially under low-resource settings. The author works with pre-trained DeepSpeech2 and Wav2Vec2 acoustic models to develop benefit-specific ASR systems. The domainspecific data are collected using proposed semi-supervised learning annotation with little human intervention. The best performance comes from a fine-tuned Wav2Vec2-Large-LV60 acoustic model with an external KenLM, which surpasses the Google and AWS ASR systems on benefit-specific speech. The viability of using error prone ASR transcriptions as part of spoken language understanding (SLU) is also investigated. Results of a benefit-specific natural language understanding (NLU) task show that the domain-specific fine-tuned ASR system can outperform the commercial ASR systems even when its transcriptions have higher word error rate (WER), and the results between fine-tuned ASR and human transcriptions are similar

death. One subject had manifest (asymptomatic) preexcitation on the ECG. Evidence of LVH was noted in 45% of the athletes using commonly applied criteria. Complete/incomplete right bundle branch block (2%/16%) and nonspecific intraventricular conduction delays (4%) were present in a minority of tracings. QRS intervals were prolonged (102±55). No subject demonstrated a long QTc interval. ST depression was present in 2 (1%) of the subjects; ST elevation in 20%. Right axis deviation was noted in 38% of the athletes. Conclusions: Prolonged QRS intervals, ST elevation, and ECG criteria for left ventricular hypertrophy are extremely common in this population; ST depression is extremely uncommon. This study highlights the difficulties of attempting to define a ''normal'' ECG in a population of high-performance athletes, and the ability to conduct ECG ''screenings'' in such a setting.


A comparative study is conducted for paleosoils of archaeological monuments of different age within Dark Chestnut, Chestnut, Light Chestnut, and Brown Desert-Steppe soil geographical subzones. Indicators of solonetzicity in soils of the region appeared asynchronically, mainly in the third and second millennia B.C. The solonetzic stage is considered obligatory in the formation of modern Light Chestnut and Brown Soils.


The respiratory rates of four species of planktonic copepods were measured. In two of the species measurements were made with two copepodite stages, and with adult male and female specimens. The rate for Calanus finmarchicus Stage V at 17°C. was found to be 0·52 μl./cop./hr., a figure which agreed with previous measurements. For all the species and stages studied the respiratory rate was found to be closely proportional to the length to the power of 2·2. The relevance of such measurements to conditions in the sea is briefly discussed.
