In this article the calculation, along with practical examples of near and far fields of acoustic antennas are presented. Knowing the near and far fields is important because the radiation patterns and physical measurements of the antennas depend on them. These antennas designed for measurements in air consist of transducers in flexural vibration, which give the best possibility to match acoustic impedances between air and the transducer. Specific type of transducers for acoustic antennas is described along with their schematic diagrams. Optimal design of the antenna is achieved when the near and far fields of the transducer are available. The near and far fields are described by the distribution of acoustic pressure in the area around the transducer. The necessary expressions for calculating acoustic pressure are supplied. In addition, diagrams of acoustic pressure distribution in chosen planes and lines of the environment are presented. Unidirectional radiation of the evaluated transducer in flexural vibration is achieved by a relatively small increase in the physical dimensions of the antenna. Schematic diagrams of actual antennas along with their radiation patterns are presented. A method for eliminating peripheral radiation of these antennas is also described.


【Objective】 Spring corn was the staple crop in Liaoxi area,but the shortage of precipitation and the big precipitation variation and its uneven distribution of time and space are the key limiting factor in the area.The limited rainfall can not meet the demand of stable and high yield of spring corn.Ridge film mulching and furrow seeding can collect natural precipitation effectively and improve rainfall resource availability.The purpose of this study is to make full use of the limited natural rainfall,improve water use efficiency of dry farming area and promote high and stable yield of spring corn.【Method】 Micro- rainwater-collecting planting mode by ridge film mulching and furrow seeding for spring corn was carried out for the sake of studying the effect of different planting patterns on soil water,yield and water use efficiency in 2007-2013.Four treatments were made in this experiment:ridge film mulching and furrow seeding(furrow was uncovered,T1),ridge film mulching and furrow straw mulching(T2),ridge and furrow film mulching(T3) and the traditional planting(CK).The experiment was designed by random grouping and repeated three times.The traditional planting was sowing in furrows,line spacing was 50 cm.Ridges and furrows of ridge film mulching and furrow seeding were in opposite arrangement,furrow width was 80 cm and ridge width was 40 cm,ridge height was 15 cm.The ridge was the rain collecting area.The furrow was the planting area and two lines of corn were planted.Planting density of different treatments was 52 500 plants/hm2.Seed manure was diammonium phosphate(375 kg·hm-2,N 18%,P2O5 46%)and topdressing was urea(375 kg·hm-2,N 46%).【Result】 The results showed that the ridge film mulching and furrow seeding could collect natural rainwater effectively,raise emergence rate of spring corn by 13.0% and 14.9% and emergence time was 1-2 d early in 2009-2010.Under the condition of no effective rainfall for a long time in early days,the order of increase of soil water storage in different treatments was T2T1CKT3 after an effective rainfall.T1 and T2 enhanced water infiltration depth to 60 ㎝ in planting area compared with the control,which was 40 cm.The runoff efficiency was 61% and the rate of increase of soil moisture storage of T1 and T2 was 72% and 88%.The average of soil water of T1,T2,T3 and the control was 135.27 mm,140.93 mm,127.85 mm and 118.98 mm during growth stages of spring corn,increased by 13.69%,18.45% and 7.46%,respectively,compared with the control.The yield of T1-T3 increased by 24.31%-32.58%,9.95%-17.81%,32.12%-37.16%,16.58%-27.96%,2.50%-9.40%,10.85%-29.33% and 4.14%-17.95% in 2007-2013,the average production of T1,T2 and T3 increased by 14.52%,20.01% and 23.44% compared with the control.The water use efficiency of T1-T3 increased by 24.66%-36.07%,14.12%-23.73%,38.34%-53.89%,29.07%-35.68%,1.20%-19.60% and 9.02%-32.55%,the average of water use efficiency of T1,T2 and T3 increased by 20.39%,27.94% and 28.02% compared with the control.It was also found that the effect of increase of yield and water use efficiency was significant under lower rainfall.【Conclusion】 The effect of Micro- rainwater-collecting planting mode by ridge film mulching and furrow seeding in dry farmland on rainwater harvesting,water storage and soil moisture conservation was definite after 7 years of study in semi-arid region in Liaoxi area.The technique could mitigate the negative impact of drought on spring sowing and seedlings growth in spring and enrich the theoretical basis of the rain-harvesting agriculture of dry farming in the area.By application and dissemination of the technique,it could improve rainfall resources utilization and water use efficiency and promote stable and high yield of spring corn and healthy and sustainable development of dry farming in the area.The study will provide important references for development of the rain-harvesting agriculture of dry farming in the north of China.


This paper does research in the independent development detection system for intensity of laminated veneer lumber via ultrasonic wave. By measuring the velocity of ultrasonic wave and other parameters on-line, the dynamic elastic modulus of laminated veneer lumber can be calculated through AVR as the data processing core of this system. And because of the dynamic elastic modulus showed positive correlation in plank strength, the timber grade can be divided through this system.


This thesis is an analysis of D. H. Lawrence's characterization of women by comparing the characters. The characters discussed include Mrs. Morel, Miriam Levers and Clara Dawes in Sons and Lovers and Ursula Brangwen in The Rainbow and Women in Love. Through the analysis, the conclusion is drawned that, by his characterization of women in his novels, Lawrence seemed to say that people in the modern times are deluded with false assumptions and enervated due to perverse deviation from nature and humanity and therefore the regeneration of human beings lies in facing unflinchingly up to humanity in its true state and in establishing well-balanced, reciprocally complementing relations between soul and flesh and between man and woman.


The rules surrounding the nature and transmission of women's prop erty in early modern England were remarkably unclear, and mothers were often able, as a consequence, to pass along their wealth with real care, deliberation, and invisibility. Of course, we need to take tremendous pains to define this wealth—be it in terms of personal possessions, familial property including land and jewels, or goods and favors shared by the liv ing. Such a calculus of gifts and debts and resources also reveals something about the economics of gender; that is, the ways that women's (or men's) status and influence might be measured in terms of things that are owned, produced, consumed, left to or shared with others. But my primary concern here is more basic. By studying the circulation of women's wealth, I want to recover what it meant to mother in early modern England, because—aside from the often considerable physical demands mothering placed upon many women's energies—mothering also had a significant economic com ponent that women of all classes somehow recognized and aimed to sup ply, in the form of linens and cloth, jewels and religious objects, medicines, prayers, and advice. The first part of this essay explores how many links between mothers and children were therefore conceived through—even created by—mate rial goods. I take, as a particularly striking example, Elizabeth Is use of her despised sister Mary's coronation robes, and explain Elizabeth's choice of


Here, we present a novel algorithm for frequent itemset mining for streaming data (FIM-SD). For the past decade, various FIM-SD methods in one-pass approximation settings have been developed to approximate the frequency of each itemset. These approaches can be categorized into two approximation types: parameter-constrained (PC) mining and resource-constrained (RC) mining. PC methods control the maximum error that can be included in the frequency based on a pre-defined parameter. In contrast, RC methods limit the maximum memory consumption based on resource constraints. However, the existing PC methods can exponentially increase the memory consumption, while the existing RC methods can rapidly increase the maximum error. In this study, we address this problem by introducing the notion of a condensed representation, called a $\Delta$-covered set, to the RC approximation. This notion is regarded as an extension of the closedness compression and when $\Delta = 0$, the solution corresponds to an ordinary closed itemset. The algorithm searches for such approximate closed itemsets that can restore the frequent itemsets and their frequencies under resource constraint while the maximum error is bounded by an integer, $\Delta$. We first propose a one-pass approximation algorithm to find the condensed solution. Then, we improve the basic algorithm by introducing a unified PC-RC approximation approach. Finally, we empirically demonstrate that the proposed algorithm significantly outperforms the state-of-the-art PC and RC methods for FIM-SD.


Tumour Genotypes Account for Survival Differences in Right and Leftsided Colon Cancers. Ward et al. Surgeons have long suspected that precise cancer location within the lower gastrointestinal tract influences outcome in terms of cancer survival. To our predecessors, anatomical location tended to focus on rectum versus colon and the importance of surgical technique was emphasized. The resultant improvements in survival seen for rectal cancer from the 1980s onwards owed much to this attention to detail as well as improved staging. The division between rectum and colon was simplistic and subsequently differences in colon cancer survival have been a source of much research endeavour over the past 20 or so years. Whether or not surgical techniques such as complete mesocolic excision deliver the benefits to cancer survival as originally proposed by some remains a source of debate [1]. What is clear is that our understanding of the relevance of genomics is going to be increasingly important in this sphere [2]. Microsatellite instability is one mechanism that may account for differences in survival between left and right colon cancers. In this article by Ward et al [3] they hypothesised that other genes differentially expressed may be of importance in determining survival. Using publicly available data from The Cancer Genomes Atlas (TCGA) they demonstrated that mutations in five genes had a significant effect on survival. These five genes are not normally associated with the cancer syndromes that surgeons are routinely familiar with (Lynch, FAP, MAP etc). Further genomic data will come over the following decade, especially as the UK 100000 Genomes project begins to report and the implementation of gene panels becomes embedded into routine practice. Surgeons will need to be cognisant that such changes are coming and learn how to counsel their patients appropriately. The long promised benefits of genomic medicine are about to be realised.


In recent years numerous studies have proved the immune-regulatory properties of vitamin D, and how it can affect the course of allogeneic haematopoietic stem cell transplantation (HSCT). Its deficiency can potentially lead to complications, particularly acute or chronic GvHD, having a negative impact in post-HSCT outcomes. Despite the evidence gathered so far, current clinical guidelines only focus on the role of vitamin D in bone health and mineral metabolism, neglecting the implications of vitamin D within the immune system. As a consequence, patients may not be routinely assessed for this and treated accordingly. This survey, carried out by the Transplant Complications Working Party of the European Society for Blood and Marrow Transplantation (EBMT), aims to describe the current clinical practice across the EBMT HSCT Programmes to acknowledge possible discrepancies. It could lead to the development of recommendations to standardise criteria and harmonise the management of vitamin D deficiency in patients undergoing allogeneic HSCT, advocating regular measurement of vitamin D, and supplementation if required, as part of the standard of care of HSCT recipients. INTRODUCTION Vitamin D deficiency is a global health concern. Risk factors include age, poor oral intake of vitamin D-enriched aliments and malabsorption. In Europe it affects habitants from different latitudes, including those living in Mediterranean countries. It is well known that haematopoietic stem cell transplant (HSCT) recipients are at high risk for vitamin D deficiency and bone abnormalities. Vitamin D acts as a hormone with pleiotropic effects on the heart, bone metabolism and immune system among others. Studies carried out within the last decades have contributed to a better understanding of the immune-regulatory properties of vitamin D and its biological action in the course of HSCT. Despite this, clinical guidelines in HSCT have only focused on the role of vitamin D in bone health and mineral metabolism but there is little recognition of the potential contribution of vitamin D deficiency in postHSCT complications such as graft-versus-host disease (GvHD). Because of this clinicians worldwide may be managing patients differently and geographical location, endemic diet and local factors could impact on patients care. In order to audit the current clinical practice to better understand differences in the management of vitamin D deficiency in allogeneic HSCT patients, we have conducted an online survey across the European Society for Blood and Marrow Transplantation (EBMT) affiliate centres. Our results could lead to future development of recommendations to standardise criteria towards a more harmonised process, advocating regular measurement of vitamin D and supplementation, if required, as part of the standard of care of HSCT recipients. MATERIAL AND METHODS HSCT programme directors of 326 EBMT affiliate allogeneic transplant centres from 42 countries were invited to participate in an online survey comprising 34 questions, divided in different categories such as diagnosis, prescription of vitamin D replacement or follow-up. This survey was developed by the authors and, prior to its launch, it was thoroughly reviewed by 7 HSCT specialists and amended accordingly. This survey was carried out from September to November 2018, and data was analysed consequently. The results are given as frequencies of the responder centres to provide a better understanding of the outcomes.


Objective: To assess the sensitivity and specificity of bedside swallowing evaluation for detecting tracheal aspiration. Method: Thirty patients who complained of swallowing difficulty or had potential for dysphagia were evaluated using videofluoroscopy and bedside swallowing evaluation for dysphagia. The bedside swallowing evaluations included gag reflex, laryngeal elevation, water swallowing test and swallowing provocation test. We compared bedside swallowing evaluations with videofluoroscopy to determine the sensitivity and specificity in detecting tracheal aspiration. Results: The comparison of the all combination of bedside swallowing evaluation and videofluoroscopic results suggested that the sensitivity and specificity in the detection of tracheal aspiration was 84.6%, 47.0% respectively. Conclusion: Bedside swallowing evaluations are limited for screening test of tracheal aspiration, so videofluoroscopic swallowing studies would be necessary to evaluate swallowing difficulty.


From Introduction: "In 1954, the AEC presented the "five-year plan" for power reactor development, briefly outlined in Table I-1. The program proceeded and other reactors were added as a result of the incentives indicated in the outline."


Objective: To determine whether a polymorphism the in δ-aminolevulinic acid dehydratase (ALAD) gene modifies the neurotoxicity of lead in older adults. Methods: The authors studied men participating in the Department of Veterans Affairs' Normative Aging Study, assessing their recent exposure to lead by measuring blood lead (n = 915) at each triennial clinic visit, and, beginning in 1991, assessing their cumulative exposure by measuring lead levels in tibia (n = 722) and patella (n = 720), using K-shell x ray fluorescence. Starting in 1993 and again at each triennial visit, the authors administered the Mini-Mental State Examination (MMSE) to assess their cognitive functioning. The relation of the lead biomarkers to MMSE score was evaluated and this association was compared among men who carried the variant allele, ALAD-2, versus men without the allele. Results: Sixteen per cent of men carried the ALAD-2 allele. Median tibia and patella lead levels (first-third quartile) were 19 (13–28) and 27 (18–39) μg/g. Blood lead levels were consistent with non-occupational exposure: only 6% of men had levels ⩾10 μg/dl. In multivariable adjusted analyses, higher levels of blood lead were associated with poorer performance on the MMSE. This association was most pronounced among ALAD-2 carriers, among whom a 3 μg/dl increment in blood lead (the interquartile range) was associated with a 0.26 point lower mean MMSE score (95% CI −0.54 to 0.01), compared with a 0.04 point lower score (95% CI −0.16 to 0.07) among non-carriers. The modest 0.22 point difference in these associations did not attain statistical significance, however (pinteraction = 0.13). The associations between bone lead levels and MMSE score did not vary by ALAD-2 status. Conclusions: Although not statistically significant, these findings suggest that ALAD genotype may modify blood lead's adverse association with cognition among older men who had community exposures to lead. However, despite a relatively large sample size and the use of sensitive methods for measuring lead burden, the evidence overall was fairly weak.


Abstract The current paper examines the role of intonation in the perception of foreign-accented speech. In order to assess how difficult it is to mentally process native, non-native and modified speech melodies, four conditions were analyzed and compared: native English, native English with Czech melody, Czech English with native melody and Czech English. The method of reaction times measurement in a word monitoring task was employed, in which 108 Czech listeners heard English sentences in the explored conditions and pressed a button when hearing a target word. Speech melody turned out to have a relatively weak but discernible impact on perceptual processing. Interestingly, Czech English proved to be more difficult to process than native English, although the listeners were Czech. The implementation of English F0 contours on Czech English speech slightly alleviated the cognitive load, however, the second hybrid, native English with Czech melody, pointed to the opposite direction. The causes of this discrepancy were investigated, particularly higher degrees of collocability in certain expressions.


A new hyperspectral image denoising algorithm, called the dual deep convolutional neural network (DD-CNN), is proposed in this paper. In contrast to internal denoising methods that utilize only the features from the target noisy image, the DD-CNN extensively explores the similarities between the target noisy image and the clean reference image from other bands. As external data, the reference images are selected based on the structural similarity index metric (SSIM). The DD-CNN is composed of two CNNs: one is responsible for extracting the features of the target image, and the other is responsible for extracting features from the reference image. A new activation function is proposed that activates the two types of features in the DD-CNN. Based on the dual structure and the new activation function, the external features extracted from the reference images are thoroughly integrated into the internal features of the target noise image. We experimented on different datasets with different noise levels; we also tested special cases for reference images with extra or undesirable features. The DD-CNN algorithm can effectively utilize the similarity between the external image and the target image. When the noise level is high, the advantages of the DD-CNN are obvious.


Real quantum heat engines lack the separation of time and length scales that is characteristic for classical engines. They must be understood as open quantum systems in non-equilibrium with time-controlled coupling to thermal reservoirs as integral part. Here, we present a systematic approach to describe a broad class of engines and protocols beyond conventional weak coupling treatments starting from a microscopic modeling. For the four stroke Otto engine the full dynamical range down to low temperatures is explored and the crucial role of the work associated with the coupling/de-coupling to/from reservoirs as an integral part in the energy balance is revealed. Quantum correlations turn out to be instrumental to enhance the efficiency which opens new ways for optimal control techniques.


With the advent of the era of Internet, network public opinion in colleges and universities has become an important part of social public opinion, for an increasing number of college students are expressing their personal emotion, opinion and criticism through the Internet. On the one hand, network public opinion can strengthen college students' sense of social responsibility, their consciousness of democratic participation and their spirit of master, thus improving their ideological awareness; on the other hand, it is so easy to spread irrational emotion that college students are more vulnerable to the influence of extreme speech and may lose their control in behaviors. Therefore, in order to build harmonious campus culture, it is proposed to establish and improve the mechanism of network public opinion in colleges and universities, strengthen the management and guidance of campus network public opinion, and further optimize the environment of network public opinion in colleges and universities.


- There are books of every sort available at libraries. Web-based software called Intranet Library Management System is used. This system has a list of all the books and allows remote users to view it simultaneously from wherever on campus. However, users need to be signed up for that. Two tiers of architecture make up this system. Students submit requests, which the server receives, processes, extracts data from the database, and then returns the completed request back to the client. This system offers a unique interface and login for students and librarians. Students may look for books online and renew their books. The librarian can change the database. They may simply send messages to the librarian from any location within the campus to propose new books. They may examine the due dates and issuance and return dates for any books. This system produces reports that may be used to evaluate the performance of the library. The management can then take the necessary action to upgrade the facilities.

: In the era of globalization, intercultural interactions have become more frequent than ever before. The ultimate goal of foreign language education in China has expanded from developing language learners' linguistic skills to promoting their intercultural competence. By reviewing the literature on intercultural competence at home and abroad, the author attempts to propose a model of intercultural competence for English learners in the context of Chinese foreign language education, which includes linguistic competence, cultural knowledge, attitudes, and behavioral skills. Next, suggestions are given to promote intercultural competence in foreign language teaching considering the failure of effective development of intercultural competence in Chinese learners of English. Furthermore, the author argues that foreign language teachers' intercultural competence and intercultural teaching competence play an important part in the process of development of intercultural competence in language learners.


Experimental and modeled data of the thermal properties of holographic planar concentrator photovoltaic modules is presented. The low concentration and increased area of the panel configuration produces a net decrease in panel operating temperature.


Realization of arbitrary transfer functions by a special class of multiple-loop feedback configuration is investigated. The n th-order system consists of n nominally identical single-pole active stages with arbitrary but constant interconnections. The constraints on the sensitivity functions with respect to the active stages of such a system are obtained. is shown that the effect of identical perturbations of the gains of active stages, such as those which may be expected due to environmental variations, is invariant for a given transfer function, and hence can be accurately predicted. Subject to these constraints, conditions are derived for the minimum of a suitably defined multiparameter sensitivity index, which may then be used to minimize the effect of mutually independent random perturbations of the gains, such as those expected due to manufacturing tolerances. For second-order systems, the optimal design is obtained analytically. For higher order systems, a general optimization scheme, employing steepest descent from an initial design, is outlined. The optimal design of a fourth-order stagger-tuned bandpass filter is presented as an illustration.

Thrombotic disorders, such as venous thromboembolism (VTE) and acute ischemic stroke, are highly prevalent,1 morbid, and anxiety-provoking conditions for patients, their families, and providers.2 Often, a clear cause for these thrombotic events cannot be found, leading to diagnoses of "cryptogenic stroke" or "idiopathic VTE." In response, many patients and clinicians search for a cause with thrombophilia testing. However, evaluation for thrombophilia is rarely clinically useful in hospitalized patients. Test results are often inaccurate in the setting of acute thrombosis or active anticoagulation. Even when thrombophilia results are reliable, they seldom alter immediate management of the underlying condition, especially for the inherited forms.3 An important exception is when there is high clinical suspicion for the antiphospholipid syndrome (APS), because APS test results may affect both short-term and long-term drug choices and international normalized ratio target range. Despite the broad recommendations against routine use of thrombophilia testing (including the Choosing Wisely campaign),4 patterns and cost of testing for inpatient thrombophilia evaluation have not been well reported. In this issue of Journal of Hospital Medicine, Cox et al.5 and Mou et al.6 retrospectively review the appropriateness and impact of inpatient thrombophilia testing at 2 academic centers. In the report by Mou and colleagues, nearly half of all thrombophilia tests were felt to be inappropriate at an excess cost of over $40,000. Cox and colleagues identified that 77% of patients received 1 or more thrombophilia tests with minimal clinical utility. Perhaps most striking, Cox and colleagues report that management was affected in only 2 of 163 patients (1.2%) that received thrombophilia testing; both had cryptogenic stroke and both were started on anticoagulation after testing positive for multiple coagulation defects. These studies confirm 2 key findings: first, that 43%-63% of tests are potentially inaccurate or of low utility, and second, that inpatient thrombophilia testing can be costly. Importantly, the costs of inappropriate testing were likely underestimated. For example, Mou et al. excluded 16.6% of tests that were performed for reasons that could not always be easily justified—such as "tests ordered with no documentation or justification" or "work-up sent solely on suspicion of possible thrombotic event without diagnostic confirmation." Additionally, Mou et al. defined appropriateness more generously than current guidelines; for example, "recurrent provoked VTE" was listed as an appropriate indication for thrombophilia testing, although this is not supported by current guidelines for inherited thrombophilia evaluation. Similarly, Cox et al included cryptogenic stroke as an appropriate indication to perform thrombophilia testing; however, current American Heart Association and American Stroke Association guidelines state that usefulness of screening for hypercoagulable states in such patients is unknown.7 Furthermore, APS testing is not recommended in all cases of cryptogenic stroke in the absence of other clinical manifestations of APS.7 It remains puzzling why physicians continue to order inpatient thrombophilia testing despite their low clinical utility and inaccurate results. Cox and colleagues suggested that a lack of clinician and patient education may explain part of this reason. Likewise, easy access to "thrombophilia panels" make it easy for any clinician to order a number of tests that appear to be expert endorsed due to their inclusion in the panel. Cox et al. found that 79% of all thrombophilia tests were ordered as a part of a panel. Finally, patients and clinicians are continually searching for a reason why the thromboembolic event occurred. The thrombophilia test results (even if potentially inaccurate), may lead to a false sense of relief for both parties, no matter the results. If a thrombophilia is found, then patients and clinicians often have a sense for why the thrombotic event occurred. If the testing is negative, there may be a false sense of reassurance that "no genetic" cause for thrombosis exists.8 How can we improve care in this regard? Given the magnitude of financial and psychological cost of inappropriate inpatient thrombophilia testing,9 a robust deimplementation effort is needed.10,11 Electronic-medical-record–based solutions may be the most effective tool to educate physicians at the point of care while simultaneously deterring inappropriate ordering. Examples include eliminating tests without evidence of clinical utility in the inpatient setting (ie, methylenetetrahydrofolate reductase); using hard stops to prevent unintentional duplicative tests12; and preventing providers from ordering tests that are not reliable in certain settings—such as protein S activity when patients are receiving warfarin. The latter intervention would have pre*Address for correspondence and reprint requests: Lauren Heidemann, MD, 1500 E Medical Center Drive, SPC 5376, Ann Arbor, MI, 48109-5376; Telephone: 734-647-6928; Fax: 734-232-9343; E-mail: firstname.lastname@example.com


Fluoro-containing homo- and copoly(arylates) based on terephthaloyl chloride, hydroquinone, and fluoro-containing bis(phenols), namely, bis(4'-hydroxyphenyl)-2,2-hexafluoropropane, 4,4'-bis(hydroxyphen-oxy)tetrafluorobenzene, and 4,4'-bis(hydroxyphenoxy)octafluorodiphenyl, were synthesized by the solution acceptor-catalytic polyesterification, and the properties of the resulting polymers were studied. The use of bis(4'-hydroxyphenyl)-2,2-hexafluoropropane, 2-hydroxyphenoxy derivatives of tetrafluorobenzene, and 2-and 4-hydroxyphenoxy derivatives of octafluorodiphenyl leads to the formation of LC homo- and copolymers. It was demonstrated that the introduction of chlorine atoms into the ortho position of bis(4'-hydroxyphenyl)-2,2-hexafluoropropane and the employment of dimeric bis(4'-hydroxyphenyl)-2,2-hexafluoropropane bring about the production of homo- and copolymers devoid of LC properties.


In this paper, the mechanical and thermal properties of compressed thin film titanium films with 150nm thickness deposited on an organic glass substrate under mechanical and thermal loads were measured and characterized. In order to simulate the thin films in IT which subjected compound loads and to produce the buckle modes, the external uniaxial compression and thermal loading are subjected to the specimen by the symmetric loading device and the electrical resistance film in this experiment. The temperature of the thin film deposited on substrate was measured using thermoelectric couple. The range of temperature accords with the temperature range of the MEMS. It is found that the size and number of the delamination and buckling of the film are depended upon the pre-fixed mechanical loading. The transient conduction and thermal stability of the film and substrate was studied with finite element method.


The emergence of new research methods makes it possible to study the tissue, structural, cellular, and molecular causes of atrial fibrillation (AF). Recently, the role of interstitial telocyte cells in the pathogenesis of AF has been actively discussed. Telocytes are a special type of interstitial cells identified in many organs and tissues, including the heart. The roles of telocytes in the myocardium are diverse: they have pacemaker activity, and carry out structural and coordination communication between cells. The ability of these cells to change the speed of the electrical pulse in the atrial and ventricular myocardium has been proven. Telocytes form "atypical" connections with almost all types of cells in the human heart, which collects them in an integrated network. Using electron microscopy, it was found that interstitial cells have different types of connections in the network and can integrate "information" from the vascular and nervous systems, interstitial, immune system, stem cells, progenitor cells, and contractile cardiomyocytes. Currently, the results of studies have been obtained that prove both positive and negative effects of telocytes on the occurrence of various diseases of the cardiovascular system. The role of telocytes in AF arrhythmogenesis remains a subject of discussion. The unique properties of telocytes in providing intercellular contacts, transmitting genetic information, and their ability to regenerate heart tissue are undoubtedly the most promising areas of modern cardiology. There is evidence of both direct and indirect effects of telocytes on the electrophysiological properties of the myocardium. There is no doubt that the development of this area opens up new therapeutic targets for the prevention and treatment of AF.


Computer applications have considerably shifted from single data processing to machine learning in recent years due to the accessibility and availability of massive volumes of data obtained through the internet and various sources. Machine learning is automating human assistance by training an algorithm on relevant data. Supervised, Unsupervised, and Reinforcement Learning are the three fundamental categories of machine learning techniques. In this paper, we have discussed the different learning styles used in the field of Computer vision, Deep Learning, Neural networks, and machine learning. Some of the most recent applications of machine learning in computer vision include object identification, object classification, and extracting usable information from images, graphic documents, and videos. Some machine learning techniques frequently include zero-shot learning, active learning, contrastive learning, self-supervised learning, life-long learning, semi-supervised learning, ensemble learning, sequential learning, and multi-view learning used in computer vision until now. There is a lack of systematic reviews about all learning styles. This paper presents literature analysis of how different machine learning styles evolved in the field of Artificial Intelligence (AI) for computer vision. This research examines and evaluates machine learning applications in computer vision and future forecasting. This paper will be helpful for researchers working with learning styles as it gives a deep insight into future directions.


hood. The patients with splice site mutations had the highest incidence of lymphomas (seven of 58 kindred or 12Æ1%). For intron 6 splice site mutations, the incidence was four of nine kindred (44%, statistically different from the incidence for all mutations, v test, P < 0Æ0002). For the single mutation intron 6 (+ 5), g fi a, the incidence was three cases in seven kindred. We previously demonstrated the discordant expression of WASP in blood cells of five patients with two intron 6 mutations (Shcherbina et al, 1999). Whereas T cells of these patients had low but readily detectable levels of WASP ( 10–20% of normal levels), the patients' peripheral B cells, as well as their Epstein–Barr virus-transformed B-cell lines, did not express the protein. Similar discordance between T and B cells was also demonstrated for a patient with an exon 1 nonsense mutation, who died of lymphoma, and two members of a family with an intron 7 splice site mutation, who have mild disease. We propose that discordant expression of WASP in T and B cells is an indication of increased risk of lymphomas in patients, even for those with an otherwise mild course of the disease. Bone marrow transplantation may be indicated for this subgroup of mild WAS patients.


Then, in theory, we could employ the Proton neutralization, namely, by protons emission, Injection (conveying; load) protons into the nucleus of spent fuel, making the nucleus of spent fuel obtains extra protons and to neutralize the redundancy π-mesons, makes the nucleus of spent fuel proliferating into a stable nuclide, become the new substances which has no redundancy π-mesons, and then missing their radioactivity.


Heterostructure of GaN:Mn/GaN on silicon substrate has been grown succesfully. GaN film has been grown on silicon substrate by using PA-MOCVD (plasma assisted metal organic chemical vapor deposition) method at temperatur of 650 o C – 700 o C. On the other hand, GaN:Mn film has been done on GaN film by using ion implantation technique. Mn ion has been implanted on top layer of GaN film.

Two coronal mass ejections (CME1 and CME2) were observed on November 9, 2002. CME1 was estimated to start around 11 UT, directed to the Northwest with estimated average plane-of-the-sky speed of 530 km/s. CME2 was associated with a GOES M4.6 X-ray flare which started at 13:08 UT in AR0180 and was directed to the Southwest with estimated average speed of 1840 km/s. The two CMEs seem to interact around 13:50 UT and two groups of DH type III bursts are observed after it. The radio source locations observed by the Nançay Radioheliograph (NRH) at 14:05 UT at 164 MHz suggest that the radio emission might be originating from the area where the two CMEs interact over the western limb. The calculated proton onset time from the SOHO ERNE data is close to the estimated CME interaction time.


Rural industry is the fastest growing sector in China's economy and made up 27.52% of the GNP in 1990. The development of rural industry not only enhances the peasants' living standard, but also demonstrates the advantages and potential of a new ownership system. Along with the development of the rural industry, however, some serious environmental problems have emerged in the agriculture. Traditional agriculture and farmers are rapidly disappearing in the developed rural industrial areas. Due to some unique characteristics of rural industry, such as its wide distribution, small size and frequent production change, a set of new environmental problems have arisen. These problems threaten a vast area of China's best cropping land. Solving those problems is beyond the capacity of current agricultural and industrial policies, because these problems are directly related to China's political system. The author proposes a set of strategies and policies that, under the current political constraints, may mitigate t...


Mesenchymal stem cells mostly exist in bone marrow and have the function of multipotential differentiation.Mesenchymal stem cells can differentiate bone and cartilage tissues under some circumstances and have some special characters,so mesenchymal stem cells have been applied to treat the bone and cartilage tissues destruction that caused by some diseases such as woundes and rheumatic diseases.Otherwise,mesenchymal stem cells can be modified by some exogenous gene and achieve positive effects,so mesenchymal stem cells would be applied widely in clinical in the future.


The time spread of the rays collected by a large diameter imaging atmospheric Cherenkov telescope (d∼20–30 m) is investigated. We compare the influence of the geometry of the spherical and parabolic reflectors on the shape and duration of collected Cherenkov light. It is shown that the design‐induced additional widening of the collected Cherenkov light pulse is essential for the spherical reflector of Davies‐Cotton type, and is negligibly small for the parabolic reflector. At the detection of 10 GeV γ‐showers, the pulse width on the spherical telescope's focal plane may reach 15–20 ns instead of 5–8 ns inherent to the incident light pulse itself. In the case with a parabolic telescope the pulse widths of the light incident on the telescope disk and collected onto the camera are almost identical.


In this study, the relationship between personality and a preference for either arthouse or mainstream movies is investigated. Research on this topic is very ample. By means of a survey, personality is assessed using the NEO-FFI and preference for either type of movies is assessed by using nine statements and summaries based on non-existent movies. The subjects were mainly University students. Results show that a significant effect has been found between a preference for arthouse movies (based on the nine statements) and the openness personality trait. The summaries didn't measure a difference between arthouse and mainstream, therefore a suggestion for future research is using scenes from real movies instead of movie summaries.


The system reliability analysis of long-span cable-stayed bridges is difficult because the failure of the structural systems may be happened in many different failure modes.But only the main failure modes contribute most to the failure probability of the structural system.The β-unzipping method is simple and reasonably accurate method to find the main failure modes.On the other hand,the reliability indices of the components need to be computed in this method.The finite element reliability method can be used for this purpose which is an efficient and accurate method for the reliability analysis.The method is applied to the system reliability assessment of a long-span cable-stayed bridge.The result showed that the failure of the cables plays a key role in the failure of the total bridge.


A large intracavernous carotid aneurysm was angiographically demonstrated in a 29 years old woman suffering from a persistent isolated abducens nerve palsy. CT brain scan failed to reveal the lesion. The usefulness of performing angiography in the cases of isolated abducens palsy of undetermined nature, is stressed.


We present a method to calculate integrals over monomials of matrix elements with invariant measures in terms of Wick contractions. The method gives exact results for monomials of low order. For higher-order monomials, it leads to an error of order 1/Nα, where N is the dimension of the matrix and where α is independent of the degree of the monomial. We give a lower bound on the integer α and show how α can be increased systematically. The method is particularly suited for symbolic computer calculation. Explicit results are given for O(N), U(N), and for the circular orthogonal ensemble.


In this paper, we propose a hyper-heuristic approach for the NP-Hard optimization variant of the satisfiability problem, namely MAX-SAT. A hyperheuristic is a high-level method that incorporates a set of low-level heuristics to handle classes of problems rather than solving one problem. In this paper, we investigate a new selection strategy based on both choice function and randomness to select adequate low-level heuristics at any given time for solving the MAX-SAT problem.

Steady electron Internal Transport Barriers (ITBs) are obtained in FTU by the combined injection of Lower Hybrid (LH) up to 1.9 MW, and Electron Cyclotron (EC) up to 1.2 MW, radio frequency waves. ITBs occur during either the current plateau or the ramp up phase, up to peak densities ne0>1.4·10 20 m, relevant to ITER operation, with central electron temperatures Te0>5.5 keV are sustained for as long as the heating pulse (>35 confinement times). At ne0≈0.8·10 20 m Te0 can be larger than 11 keV. The ITB extends over an internal region with an almost flat or slightly reversed q profile and qmin≈1.3, resembling that of the hybrid regimes, that is fully sustained by off-axis LHCD. This causes also a pretty good alignment of the bootstrap current generated by the ITB large pressure gradients with the externally driven current. Despite the longest ITB is about one ohmic current relaxation time, steadiness is attained much earlier, on times of the order of the energy confinement and of the electron fast tail generation and no evolution is observed thereon. Reflectometry shows a clear change in the turbulence close to the ITB radius consistent with the reduced electron transport. Significant collisional ion heating is also observed, but thermal equilibrium with the electrons cannot be attained since the e -i equipartition time is always 4-5 times longer than the energy confinement time. The global ion transport is not degraded, rather the transport analysis must invoke a reduction of χi respect to the ohmic phase to account for the 10-fold increase of the neutron rate. The control of the ITB radius can be achieved by varying the LH power deposition profile that is affected mostly by the total current.


A new transfer matrix approach has been worked out to test the predic- tions of the molecular-field renormalization group for square Ising clusters with a linear size up to L < 11. The convergence of the finite-size critical cou- plings towards the exact value for the molecular-field renormalization group is shown and the limit of the ratio yh/yt consistent with the corresponding universal value is revealed.


the rose production became important because more p eople want to decorate their gardens, orchards, and to improve the quality and the view o f the green space. That's why is very important to use a good quality of the planting material. For the roses thi material is obtained in nurseries by grafting. The experiments want to answer to the question how the quality of the material is influence by the soi l and climatic condition in Unirea-Alba.


The identification of functional processes taking place in microbiome communities augment traditional microbiome taxonomic studies, giving a more complete picture of interactions taking place within the community. While there are applications that perform functional annotation on metagenomes or metatranscriptomes, very few of these are able to link taxonomic identity to function or are limited by their input types or databases used. Here we present MetaFunc, a workflow which takes input reads, and from these 1) identifies species present in the microbiome sample and 2) provides gene ontology (GO) annotations associated with the species identified. In addition, MetaFunc allows for host gene analysis, mapping the reads to a host genome, and separating these reads, prior to microbiome analyses. Differential abundance analysis for microbe taxonomies, and differential gene expression analysis and gene set enrichment analysis may then be carried out through the pipeline. A final correlation analysis between microbial species and host genes can also be performed. Finally, MetaFunc builds an R shiny application that allows users to view and interact with the microbiome results. In this paper, we showed how MetaFunc can be applied to metatranscriptomic datasets of colorectal cancer.


Dermal sensitization resulting from the raw materials of polyurethanes like diisocyanates has been frequently reported,however the study on allergic reactions to polyurethanes themselves was seldom seen.In this study,the delayed hypersensitivity to three polyurethanes for vascular grafts has been investigated according to guinea pig maximization test(ISO 10993-10).Among the three materials,PCUL2 was a polycarbonate urethane chain-extended with lysine while PCUL2-PO and PCUL2-PN were comb-like polymers from PCUL2 backbones grafted with polyethylene glycol(PEG) diglycidyl ether and PEG bisamine respectively.These materials were highly porous with functional groups intended for conjugating with bioactive molecules to induce in situ endothelialization.The test groups were saline extracts prepared at(70± 2) ℃ for(24 ± 2) h using the maximum extraction concentration(0.1 mg /mL).The saline was used as negative control while the 2,4-dinitrochlorobenzene in ethanol(1 g /L) was used as positive control.The results showed that the test groups induced minor hypersensitivity(2 /12 for PCUL2-PO;1 /12 for the others).The negative results of the delayed hypersensitivity to the tested polyurethanes suggest that further in vivo studies are worthwhile.


The multiple scattering Xα method applied to an embedded CuCl5−6 cluster is used to describe the electronic structure of Cu+ in NaCl. Several calculations have been performed with different Cu–Cl distances in order to reach the equilibrium distance. The harmonic force constant of the vibrational breathing deformation of the cluster, deduced from the total energy curve vs the bond distance is in large agreement with experimental results, while the equilibrium distance is predicted slightly larger than the NaCl bulk value.


Andi Aditya Hardinto, 2019: The Influence of Executive Compensation,
Ownership Structure and Operational Costs of Operating Income (BOPO) on the
Quality of Bank Loans in Indonesia in 2015-2017. State University of Jakarta
Credit quality is one of the factors in loan management to avoid credit risk early,
because credit risk can affect the sustainability of the banking business. In
addition, credit quality is used to determine the level of reserves of potential
losses due to non-performing loans. This study aims to examine internal loan
management factors is, Executive Compensation (EXCOM), Ownership Structure
(GOVOWN), and Operational Income Operational Costs (BOPO) on Loans
Quality (Y) in Indonesia in 2015-2017.
This study uses secondary data with a focus on the banking sector listed on the
Indonesia Stock Exchange for the period 2015-2017. This study used purposive
sampling to obtain 120 total observations over three years. This study uses a
multiple regression analysis method to test the three hypotheses with a
significance level of 5% and use Eviews Version 8.
Based on the results of multiple regression analysis tests that have been done, it
can be concluded that Executive Compensation, Ownership Structure, and
Operational Income Operational Costs (BOPO) partially have a significant
positive effect on Loans Quality. The results explained that each variable in this
study was able to maintain credit quality because banks listed on the Indonesia
Stock Exchange were competent in managing loan management.
Keywords: Executive Compensation, Ownership Structure, Operational Income
Operating Costs (BOPO), and Loans Quality.


The primary xylem differentiation in new, white roots of differing root diameters in 3-year-old peach Prunus persica (L.) (Batsch) trees supplied different amounts of nitrogen was examined. Primary xylem differentiation as the number of xylem ridges in cross-sections of new, white roots increased significantly with increasing root diameters, irrespective of differing amounts of nitrogen applications. The number of xylem ridges ranged from three to seven in peach roots. These results indicate that the numbers of thick roots having many primary xylem cells increased more in nitrogen fertilized plants than did those in no-nitrogen ones.


The ability to move on different types of soils is one of the main indicators of the efficiency of mobile vehicles in off-road conditions. The movement of such special mobile machines is carried out due to the interaction of the propulsion with the support surface. Therefore, significant reserves to increase productivity and reduce the cost of technological and transport works are laid in reducing energy consumption when the engine interacts with the surface. On the process of interaction of the wheel drive with the deformable support surface it is established that the parameters of this interaction depend on a number of factors: normal load, angular velocity and torque. In the General case, the parameters of interaction of each engine change when changing the mode of movement of the wheeled vehicle, and the ability to change the air pressure in the tires when driving on different support surfaces allows to increase the performance of the wheeled vehicle In the study of the caterpillar, it was found that the pitch of the caterpillar, the stiffness of the caterpillar, the angular stiffness of two adjacent tracks, reducing the pitch of the caterpillar chain, reducing the stiffness of the caterpillar, increasing the angular stiffness of two adjacent tracks, affect the efficiency of the machine. The scientific novelty of the study is to develop a method of choosing the engine of a special mobile machine that works off-road, in the process of its design. Wheel or crawler solutions will mainly determine the performance and efficiency of special purpose vehicles. The choice of engine for special mobile machines is based on a set of criteria. The criteria determine the importance of the implementation of the tasks in relation to the efficiency of functioning. Knowing the sowing capacity of the soil, and taking into account the possibility of movement of a particular special mobile machine depending on the type of soil, you can choose one or another type of engine.


Medical Diagnosis and Treatment of Alcoholism Jack H. Mendelson and Nancy K. Mello; eds. 699 pages. New York: McGraw-Hill; $55.00. The tragic societal losses caused by alcohol affect the work of all physicians. To what extent does this book meet the formidable challenge of enhancing the medical care system's responses? Babor's chapter succinctly and readably presents for the generalist the complex controversies regarding definitions and diagnosis of alcoholism. The delightful geriatric vignettes in Ofman's chapter vividly describe the pathos and show how coordination of services produces dramatic outcomes, even with the cognitively impaired elderly. Unfortunately, the text immediately preceding these stories iterates the lack of data on this admittedly understudied group. Lewis writes dynamically about treatment. He focuses on primary care and presents behavioral interventions and valuable how-to clinical notes, backed by rationale and data. Schuckit's chapter features academic and dry writing that outlines well the elements and principles of treatment. However, some unsubstantiated treatment suggestions are debatable; for example, he theorizes that generalists might treat patients in medical or psychiatric units without groups or counselors. Addiction specialists will appreciate the up-to-date reviews of the medical aspects of alcoholism, such as the encyclopedic endocrine chapters, which integrate animal and bench research with clinical data and interpret them as well. The book also includes fascinating current findings on molecular mechanisms of tolerance, pharmacokinetics, and neurotransmitters, but the presentations lack a consistent clinical orientation. The otherwise fine, extensive neurologic chapter is marred by reliance on classic data. The editors redress the field's male bias in four of the 17 chapters; editor Mello's chapter on the female neuroendocrine system is a well-organized goldmine, with strong clinical relevance and a good summary. In place of the abundant duplications in the book (for example, definitions, listings of medical complications, and withdrawal treatment), I would have welcomed chapters on psychiatric issues or the dual diagnosis patient, the disease/abstinence versus controlled drinking controversy, or family issues as encountered by physicians. Mendelson and Mello take a more academic, less clinical orientation than their title suggests. The abilities of researchers who need a current review, or addictionists who wish in-depth reading are more enhanced than generalists' skills. Primary care physicians might prefer a chapter in a medicine textbook, or a short primary care text on alcoholism; excellent editions of these have been recently published.

Abstract : At the Leninakan meat canning plant, where it is possible for brown rats to have access to infected meat carcasses, erysipeloid infection of the mucous membrane of the pharyngeal ring in these rodents exceeded 30.7%, while infection of rats taken from other places did not reach 4%. Feeding brown rats material known to be contaminated with a culture of erysipelothrix var. suis did not cause their death and a clinically expressed disease was not even observed. However, 44% of all the infected animals remained erysipelothrix carriers for a certain period of time (10--25 days). Rats, under the conditions present in places dealing with food, may play a specific role in the spreading of erysipeloid infection by the mechanical route and as a result of being carriers. This again emphasizes the problem of the regular and organized eradication of rats.

Schiff has, within the past twelve months, stated that beginners in this mode of treatment should proceed in a different manner than the more experienced. This statement alone from such an authority shows the unsatisfactory state of affairs. Other writers have attempted to formulate rules, but none have been universally accepted. THE PREPARATION OF THE PATIENT. To begin with : how are the surrounding healthy parts of the area to be put under treatment to be protected from the action of the x -rays? Rollins devised a box in which the tube is enclosed. This is coated on the inside with heavy lead paint and has a diaphragm of changeable size, so that the size of the cone of x -rays passing to the outside may be regulated. This contrivance is used but very little, probably partly on account of its cumbersomeness. As the surrounding healthy parts


Here we demonstrate the direct-write all-polymer nanofibers as uniaxial strain sensors for flexible and wearable devices. Compared to the state-of-art strain sensors, the unique characteristics include: direct-write all polymeric stain sensors for the first time on flexible substrates; local strain sensing with arbitrary contours and designated sensing directions; and 10X higher gauge factor than that of commercial metal strain sensors.

The Chinese language Curriculum Criterion should be introspected from three aspects: theory (curriculum theories), the representation in word and the expression in word. Therefore,the Chinese language Curriculum could be improved and the reform of the Chinese language Curriculum could also be promoted.


We deal with nonlinear periodic differential systems depending on a small parameter. The
unperturbed system has an invariant manifold of periodic solutions. We provide sufficient
conditions in order that some of the periodic orbits of this invariant manifold persist after the
perturbation. These conditions are not difficult to check, as we show in some applications. The
key tool for proving the main result is the Lyapunov--Schmidt reduction method applied to the
Poincare--Andronov mapping.


Abstract: A prototype knowledge-based diagnostic system for understanding the problems in prestressed concrete bridges is presented. The object-oriented approach is used for the system development. The system is completely interactive, making extensive use of pictures and diagrams along with textual explanation to explain difficult concepts in a multilingual environment. The system compares the new case of damage with the various types of damages that are stored in the knowledge base. It explains to the user the details of design and construction that may lead to this damage and the related repair methods. The system indicates the applicability of textual and pictorial explanations in developing an environment for the diagnosis of problems in prestressed concrete bridges.

What follows shall provide an introduction to a predominantly philosophical and polemical, but historically revealing, paper on the foundations of the theory of probability. The leading Russian probabilist Aleksandr Yakovlevich Khinchin (1894–1959) (see fig. 1) wrote the paper in the late 1930s, commenting on a slightly older, but still competing approach to probability theory by Richard von Mises. Together with the even more influential Andrey Nikolayevich Kolmogorov (1903–1987), who was nine years his junior, Khinchin had revolutionized probability theory around 1930 by introducing the modern measure-theoretic approach, which is still standard today and which allowed for a sufficiently general treatment of important new notions such as "stochastic processes." This development had its first culmination in Kolmogorov's booklet, Grundbegriffe der Wahrscheinlichkeitsrechnung, written in German in 1933, which has exerted an enormous influence world wide.


The ending -oma is ambiguous, as it can be part of 1) deverbal nouns with suffix -ma denoting 'act or result of act', 2) medical terms with suffix -oma 'malignant tumour', 3) botanical and zoological terms with suffix -oma 'set', and 4) terms with suffix -oma 'the total genetic material' in genomics whose second constituent -omics forms the new dynamic branch of omics technology. The concept of collectivity constitutes the common semantic core of suffixes -oma. The grammar of scientific sublanguage of Modern Greek has to be written.

Objective To study imaging through 18F-FDG PET-CT on established rabbit tumor model of VX2. Methods VX2 tumor cells were routinely cultured. VX2 cells were diluted to the concentration to 107/ml with RPMI1640, and 1. 0 ml was injected intoneck skin of rabbits. Rabbits were inspected by 18F-FDG PET-CT every week. After last inspection, rabbits were sacrificed. Tumor tissues were taken out and pathological sections were stained with HE. Results Tumor was found in 4 of 10 rabbits. In the first week, there was no abnormal radioactive accumulation. Since the second week, radioactive accumulation were found in 4 rabbits, and the mean diameter was 0. 8cm ×0. 6cm. After three weeks, the average tumor size was 1.8cm×1.5 cm. CT showed uniform density inside the tumor, CT value was about 30HU. PET showed obvious high radio-absorbance, T/M value was about 9. 2. Conclusion A rabbit tumor model was constructed through subcutaneous injection of VX2 tumor cells and the ratio of tumor formed was 40%. Imaging of clinical PET-CT demonstrated that VX2 tumor tissues could uptake 18F-FDG more than normal tissue, which made the basis for further study of VX2 tumor model.

Network-enabled Electronic Warfare (NEW) is to develop modeling and simulation efforts to explore the advantages and limitations of network-enabled electronic warfare concepts. The advantages of linking multiple electronic support measures (ESM) and electronic attack (EA) assets to achieve improved capabilities across a networked battleforce have yet to be quantified. In this paper, we will use radar sensors as ESM and EA assets to demonstrate the advantages of NEW in Collaborative Automatic Target Recognition (CATR). We apply the NEW to CATR via waveform diversity combining and and propose maximum-likehood (ML)-ATR algorithms for nonfluctuating target as well as fluctuating target. Simulation results show that our NEW-CATR performs much better than single sensor-based ATR algorithm for nonfluctuating targets or fluctuating targets. Conclusions are drawn based on our analysis and simulations and future research works on this research topic are discussed.


Objective To study the application value of blood optical platelet(PLT O) with Sysmex XE 2100 blood analyzer. Methods We counted the blood platelets with resistance method, optical method and manual method(comparison method), and analyzed the correlation between the results of the two former methods and the latter method statistically. Results The means from the three methods indicated no significant difference( P 0.05), but there were high correlative coefficients of the two ranges' results(PLT100×10 9/L, PLT≥100×10 9/L), P 0.01 . And the resistance method came out evident low value results in PLT100×10 9/L platelet range, but there still was larger difference in the results of some samples. Conclusions The optical method in platelet assay is more valuable in the assay of low value platelet and some samples of patients suffered from hematologic diseases.


Introduction. Aortic coarctation is a congenital defect of the cardiovascular system characterized by narrowing in the isthmus of the aorta, in which blood flow through the narrowed area is obstructed, blood pressure in the aorta increases significantly above the narrowing site, arterial hypertension syndrome develops, which can lead to a stroke. Aim. To analyze a clinical case of aortic coarctation, first detected in a 4.5-year-old child, and late- diagnosed arterial hypertension led to an ischemic stroke. Material and methods. The boy D., at the age of 4.5 years, was admitted to the hospital at the place of residence with symptoms of a stroke on the background of complete well-being. Echocardiography, electrocardiography, magnetic resonance and computed tomography of the brain, computed tomography of the chest organs with contrast, aortography, and manometry were performed. Results and discussion. The crisis course of arterial hypertension resistant to therapy was objectively noted. Echocardiography revealed coarctation of the aorta in a typical place, the defect was confirmed on computed tomography of the chest organs with contrast, on magnetic resonance imaging of the brain – extensive ischemic stroke of the right hemisphere. The early post-stroke period, post-ischemic changes in the brain made it difficult to choose cardiac surgery tactics, but given the lack of response to hypotensive therapy, it was decided to operate, resection of the narrowed aortic area with the formation of an end-to-end anastomosis was performed. Observation in the postoperative period (after 2 years) revealed hypoplasia of the distal part of the aortic arch, repeated surgery was not performed, since angiography with manometry showed a sufficient pressure gradient between the ascending and descending aorta. Currently, the child is on constant hypotensive therapy, is disabled due to neurological pathology. Conclusion. The lack of alertness of doctors regarding aortic coarctation and blood pressure monitoring did not allow early suspicion of this pathology and led to the appearance of ischemic stroke in the child, irreversible changes in the nervous system, made it difficult to choose cardiac surgery tactics.

Medicinal herbs, plants and their products show revolutionized effect in modern therapeutic system. Industries used their activity as antioxidant, antitoxin, antimicrobial, immune booster and many others and use them accordingly as the prime agent to produce cosmetics, food, drug synthesis etc. Unani is one of the traditional therapeutic system which use medicinal herbs mostly for making their herbal medicines. There are several immunomodulatory herbs along with their phytochemicals are present to serve their best. Bioassay is the method of analysis to find out the potency or concentration of any substance when effect on living things. Sars Cov-2 virus and its fatal outbreak is a real threat to modern society. To perform in vitro procedure to screened out small molecule inhibitors of this malicious pseudo typed particle cell entry, Dr. Whittaker's group use this bioassay system like PubChem AID: 1479144, PubChem AID: 1479149, PubChem AID: 1479150 and PubChem AID: 1494158. This in silico study is to show the potency of the phytochemicals of traditional herbs of Unani, as if inhibitors by means of machine learning with the help of WEKA. The ADMET study and molecular docking with Mpro (6lu7 chain A) is also done to test the druggability and binding affinity of the qualified phytochemicals.


Background: The International Caries Detection and Assessment System (ICDAS) was developed to integrate several criteria systems into one standard system for caries detection and assessment. The aim of this study was to identify Turkish dental practitioners' perceptions and experience about ICDAS II and assess how they could affect clinical decision-making. Methods: A web-based data collection form, including demographic characteristics, experience of caries detection systems, and two different clinical images with caries and treatment options, was given to Turkish dental practitioners. Data were analyzed with the chi-square test and logistic regression using SPSS 22.0 software (IBM, Chicago, IL) at a significance level of P<0.05. Results: Data collection forms were completed by 382 general dental practitioners. For the first clinical scenario 70.7% of the practitioners decided that no treatment was required. For the second clinical scenario 89.5% of the practitioners decided to perform tooth restoration. Considering the clinical scenario 2 treatment options, while practitioners working in the public hospital marked amalgam restoration at a higher rate, practitioners working in private clinics marked composite resin restoration and root canal treatment at a higher rate (P<0.05). With regard to effects on treatment choices for clinical scenarios, binary logistic regression analysis found no significant effects of gender, age, or institution (P>0.05). Conclusion: The visual caries detection system, ICDAS II, was a useful tool in standardizing caries diagnostic skills for practitioners and improving decision-making abilities on caries treatment.


Precise measurement of the water fraction in oil is of critical importance in the oil industry. Currently, cost-effective, reliable, and compact downhole measurement technologies capable of full-range three-phase measurements are not available. This article presents an ultra low power, low cost, wireless, and noncorrosive resonance sensor based on magnetoelastic technology that has been implemented by an amorphous ribbon and electromagnetic interrogation. The proposed technology enables distinguishing all three gas, water, and oil phases with amplitude changes of 75% and 99% and resonant frequency shifts of 0.46% and 3.88%, respectively, compared to the gas phase. The response of the sensor enables characterizing the water-cut range from 10% to 90%. The addition of a Teflon anticorrosion layer enables sensor deployment for extended periods of time in harsh environments.

FDI was a significant investment source in transition economies, though with marked variation across regions and time periods. FDI arrived earlier in countries that joined the EU. Transition economies experienced positive effects on growth and the labor market due to FDI inflows. FDI inflows were associated with higher levels of GDP and lower unemployment for some periods. EU member states exhibit distinct effects of FDI on firm restructuring, productivity, and employment. ElEVatOr PitCH

The Asian community in the United States has seen an enormous uptick in discriminatory experiences since the start of the COVID-19 pandemic. Asian individuals have reported discrimination within their workplaces, in their communities, and against Asian-owned businesses. Many for-profit organizations have failed to acknowledge this surge. We argue that organizations should adopt policies to protect their Asian employees and clientele. On the basis of behavioral science research and knowledge of best practices for promoting diversity and inclusion, we suggest that organizational leaders create crisis task forces to find ways to reduce discrimination against Asian employees and that the leaders more generally reaffirm organizational commitments to diversity and inclusion, communicate those commitments to stakeholders, visibly enact expected organizational norms related to diversity and inclusion, and establish or reassess accountability systems to ensure that policies and norms are followed.


On the basis of one simple grain boundary model, the trapped states of positrons at grain beunaries in pure Aluminium are solved and tthe corresponding positron annihilation lifetime spectra are calculated. The correlations between the atomic density distributions of grain boundaries and the lifetime spectra are discussedand the existing experimental results are explained theoretically.


We study a refinement of the symmetric multiple zeta value, called the tadic symmetric multiple zeta value, by considering its finite truncation. More precisely, two kinds of regularizations (harmonic and shuffle) give two kinds of the t-adic symmetric multiple zeta values, thus we introduce two kinds of truncations correspondingly. Then we show that our truncations tend to the corresponding t-adic symmetric multiple zeta values, and satisfy the harmonic and shuffle relations, respectively. This gives a new proof of the double shuffle relations for t-adic symmetric multiple zeta values, first proved by Jarossay. In order to prove the shuffle relation, we develop the theory of truncated tadic symmetric multiple zeta values associated with 2-colored rooted trees. Finally, we discuss a refinement of Kaneko–Zagier's conjecture and the t-adic symmetric multiple zeta values of Mordell–Tornheim type.


I present an ontology of the material world that is consistent with ten constraints, ten logical and metaphysical theses to which I am strongly committed. These are (1) Identity should be understood in a "classical" or "absolute," rather than a "relative," sense; (2) Material things endure through time; they are neither four-dimensional entities extended in time nor three-dimensional cross-sections of such; (3) Principles of "standard logic" (such as the law of the excluded middle or the transitivity of identity) should be universally valid, or, at worst, should fail only in bizarre science-fiction cases that have never actually occurred; (4) Modal statements about individuals should not be understood counterpart-theoretically; (5) Matter is ultimately particulate; (6) Two objects cannot be composed of the same proper parts at the same time; (7) Subject-predicate sentences whose predicate is a "mental" predicate (such as 'is in pain' or 'is thinking about Vienna') can express truths only if their subject-term denotes a thinking thing; (8) There are thinking things, and at least some of them (ourselves) are living animals; (9) What there is cannot be a matter of stipulation or convention(10) Whether certain objects add up to or compose a "larger" object depends on nothing besides their intrinsic properties and the spatial and causal relations that they bear to one another. The ontology of the material world that is presented in this book is developed in the course of an-attempt to answer the "Special Composition Question": Under what conditions do things add up to (make up, compose) a thing. (Certain things "add up to" or "make up" or "compose" a given thing just in the case that all of them are parts of it, and no two of them have a common part, and each of its parts shares a part with one or more of them.) To answer the Special Composition Question (SCQ) is to state, using only non-mereological language, when composition occurs. (SCQ is distinguished from the "General Composition Question": What is composition? This question would be answered by an analysis of composition, an analysis that was reductive in the sense that it made no use of mereological concepts. I do not attempt to answer the General Composition Question. I am inclined to think


Transabdominal ultrasonography (TAS) is a widely used imaging modality for large variety of abdominal complaints. But indeed it has limited values for diagnosis of gastrointestinal diseases. Literatures on the value of transabdominal ultrasonography on diagnosis and preoperative staging of gastric cancer are sparse. So the aim of this study is to assess the accuracy and limitations of ultrasonography for diagnosis and detection of spreading of gastric carcinoma. Fifty eight sonographically diagnosed patients were included in this study. UGI endoscopy was done in all patients. Five patients were excluded from study because of negative biopsy though endoscopy revealed suspicious lesion. The accuracy of conventional transabdominal sonography of fluid filled stomach was evaluated for diagnosis of gastric carcinoma as compared to endoscopy. The age range was between 14-75 years with mean age 43.5 years (SD ±14.2). The maximum numbers of patients (28.3%) were within the age group 40-49 years. The male and female ratio was 1.2:1. Fifty (94.3%) out of 53 patients of sonographically detectable gastric carcinoma actually have true malignancy proven by endoscopic biopsy and 3 (5.6%) were endoscopically normal & no biopsy was taken. Distal gastric carcinoma has been more precisely located than proximal by sonography. Besides this sonography provided an estimate of extragastric spread of tumour (34%) which is not possible by endoscopy. So in conclusion transabdominal sonography is an useful supportive modality for diagnosis and pre-operative assessment of exogastric spread of gastric cancer and indeed a supplementary diagnostic procedure to endoscopy. doi: 10.3329/taj.v20i1.3089 TAJ 2007; 20(1): 48-51

Purpose
The service sector is the key driver of a country's economic growth. The quality of service is more important for the survival of any organization. It is the interactive process by which the organization understands the customer and satisfies their needs. The main purpose of this study is to identify the factors influencing service quality in ocean freight forwarding and to study the association between the factors.

Design/methodology/approach
This research uses a deductive approach, which understands the theory first and collects the data. A questionnaire is designed to collect the data. The sampling technique used is two-stage sampling. First, the freight forwarders are selected and then the customers, importers and exporters are selected randomly. Likert scales are used to measure quality factors such as tangibility, reliability, responsibility, value, empathy and assurance. The association of factors is empirically evaluated. The SPSS tool is used for the correlation analysis.

Findings
An extensive review of the literature has been done to study and identify these service quality factors influencing customer satisfaction and loyalty. The result of this extensive literature review revealed that tangibility, responsiveness, reliability, trust, empathy and value are the service quality. It has been proved that there exists a significant association between the service quality factors and is positively related to the customer satisfaction.

Originality/value
Some studies have examined the freight forwarders' service quality, but not specifically related to any dimension. This study attempts to bring together the five dimensions of SERVQUAL scale and the value dimension evaluating the cost, freight charges, safety and security criteria in the industry and examines the association between the quality factors and customer satisfaction.


Background: Increasing life expectancy in the community has led to a growing prevalence of changes and disorders such as arthritis, which has been accompanied by increasing use of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs).However, its utilization pattern may differ among rural and urban elderly. Aim of the study: was to assess the utilization pattern of Non-Steroidal Anti-Inflammatory Drugs among community-dwelling elderly living in Urban versus Rural areas. Subjects & methods: Research design: A cross sectional descriptive comparative research design was used. Setting: Communitydwelling elderly's own homes in two governorates. One is rural from El-Behera Governorate, and the other is urban from Alexandria Governorate. Subjects: A convenience sample of 640 Community-Dwelling elderly with three hundred and twenty from each of the above mentioned settings. Tools of data collection: I) Mini Mental State Examination (MMSE) Scale II) Community-Dwelling Elders' NSAIDs Utilization Pattern Structured Interview Schedule composed of five parts to collect data about socio-demographic characteristics, NSAIDs utilization pattern, sources of NSAIDs information, presence of contraindications to use NSAIDs and Knowledge of the elderly about NSAIDs. Results: NSAIDs users were 580 of the study subjects from both rural and urban areas. Rural participants are significantly more likely to have higher rate relative to urban participants to use of NSAIDs as an analgesic (p<0.001), use of drug as Over-TheCounter (OTC) (p<0.001). And they have experience of NDAIDs' side effect (p<0.001). The majority of both rural and urban study subjects reported that they don't receive any instructions from the nurse about NSAIDs, with no statistically difference. Conclusion: NSAIDs utilization was significantly higher among rural than urban residence, whether it was prescribed or non-prescribed (OTC).Rural participants were significantly more likely to had poor level of knowledge about NSAIDs relative to urban participants. Recommendations: Community health and gerontological nurses have the responsibility for training the nurses who works in different rural and urban health care settings about NSAIDs.

The InP‐native oxide‐SiO2 interface system has been studied by cross sectional high‐resolution electron microscopy (HREM), x‐ray photoemission spectroscopy (XPS) depth profiling, and C‐V and G‐V measurements. The devices were prepared on InP treated in several different ways, including InP oxidized in air at about 350 °C for 68 h. HREM shows that the interface roughness varies, depending on the InP surface treatment, from 100 A for InP etched in iodic acid. Ellipsometry measurements on as‐cleaned InP indicate a native oxide of 9 to 15 A thickness, but no such oxide is clearly evident in HREM images. For the thermal oxide ellipsometry gives a thickness of 107 A, and HREM shows an oxide of ∼110 A thickness between the InP and the SiO2. HREM further shows that the thermal oxide consists of an inner layer (next to InP) about 50 A thick and an outer layer about 60 A thick, and that the oxidation roughens the InP substrate to a depth of 30–50 A. XPS sugg...


Circulating immunoreactive parathyroid hormone (PTH) was measured by a homologous, amino‐terminal, specific, immunoradiometric assay in man. In forty‐two healthy subjects the concentrations ranged between < 40 pg/ml and 120 pg/ml. No hormone could be detected in the sera of eleven patients with hypoparathyroidism, but the concentrations were clearly elevated in six patients with pseudohypoparathyroidism (range 190–1120 pg/ml). In thirty‐five patients with primary hyperparathyroidism the mean (±SEM) concentration was 283·4±42·4 pg/ml (range 100–1350 pg/ml). A significant positive correlation was demonstrated between immunoassayable hormone and serum calcium concentrations in these patients. In nine patients PTH concentrations were measured before and after parathyroidectomy. In all of them they were elevated pre‐operatively but fell to the normal range after parathyroidectomy. The disappearance of exogenously administered synthetic human PTH (1–34) from the circulation of two normal subjects was rapid with an apparent plasma half‐disappearance time (t½) between 2 and 3 min; the metabolic clearance rate was 12·9 and 9·0 ml. kg‐1, min‐1 respectively. Similarly, the disappearance of endogenous, amino‐terminal, immunoreactive PTH from the circulation of two patients with primary hyperparathyroidism after parathyroidectomy was rapid; the apparent t½ was approximately 3 min. Homologous amino‐terminal specific immunoassays for PTH can thus be useful for the study of both the acute, and chronic, changes of circulating hormone in man and represent an improvement over heterologous unselected assay systems.
