Continuous Wavelet Transform Application in Power Electronic Equipment Electromagnetic Interference Detections

In this paper,a novel approach to detect electromagnetic interference from power electronic equipment by means of continuous wavelet transform is presented.The algorithms of the proposed approach are given,followed by two case studies illustrating the process of EMI detection from the equipment layout and from components.The case studies show the proposed approach can detect EMI from EUT effectively,especially for the transient EMI that general frequency analysis such as Fourier Transform failed to be employed.
Gene-analysis of hantavirus in Anhui province

Objective To learn the genotype and characteristic of hantavirus(HV),and provide basis for the prevention and treatment.Methods Positive lung tissues of mice and sera of acute HFRS patients were inoculated in Vera cell line.Total RNA was extracted from the culture,and RT-PCR was applied to amplify the S gene of HV.The full-length sequence of S gene was obtained by sequencing and assembly.The sequencings were analysed by DNAStar and MEG4.1 to construct the phylogenetic tree,so that it could be used to identify the genotype of HV.Results The immuno fluorescent antibody assay(IFA) showed 21 positive results in 513 lung tissues of mice and 6 strains of virus isolated from the positive tissues;while 1 strain virus was isolated from 4 sera of acute patients.Compared with type HTN,SEO,SNV strain of HV,S gene of three strains of virus showed that two were type HTN and one was SEO by sequencing and analysis.The analysis of all the strains turned out 98.4% homology with standard strains.Conclusion In conclusion the genotype of HV prevalent in Anhui province are type HTN and SEO,genetic variants has not been found.
Anand Constitutive Relation of SnAgCu-nano Al and the Reliability of Solder Joints

In this paper, the constitutive relation of Sn Ag Cu-nano Al is investigated and the constitutive model is used in the finite element simulation to analyze the stress-strain response in FCBGA devices. The results show that the nine parameters of the Anand model can be fitted based on nonlinear data fitting method with different temperature and strain rate. Combining Anand model, the stress-strain response of solder joints is calculated by using the finite element method, and it is found that the distribution of stress-strain of solder joints in FCBGA device can be affected by the solder joints array, i.e., the maximum stress-strain concentrates in the concern solder joints. The results also demonstrate that the stress-strain of Sn Ag Cu-nano Al solder joints is lower than that of Sn Ag Cu solder joints, which implies that the addition of nano Al particles can enhance the reliability of Sn Ag Cu solder joints.

The Amnestic Syndrome

This chapter focuses on the amnestic syndrome or an impairment in the ability to form new memories. The chapter first describes the history of amnestic disorder and background on memory and memory function. Descriptions of the four amnestic syndromes (Wernicke–Korsakoff syndrome, transient global amnesia, mild cognitive impairment, and hysterical amnesia) are then provided. Finally, the etiology, evaluation, and treatment of amnestic syndrome are described.
Gaseous product mixture from Fischer-Tropsch synthesis as an efficient carbon feedstock for low temperature CVD growth of carbon nanotube carpets.

Low-temperature chemical vapor deposition (CVD) growth of carbon nanotube (CNT) carpets from Fe and Fe–Cu catalysts using a gaseous product mixture from Fischer–Tropsch synthesis (FTS-GP) as a superior carbon feedstock is demonstrated. This growth approach addresses a persistent issue of obtaining thick CNT carpets on temperature-sensitive substrates at low temperatures using a non-plasma CVD approach without catalyst pretreatment and/or preheating of the carbon feedstock. The efficiency of the process is evidenced by the highly dense, vertically aligned CNT structures from both Fe and Fe–Cu catalysts even at temperatures as low as 400 °C – a record low growth temperature for CNT carpets obtained via conventional thermal CVD. The grown CNTs exhibit a straight morphology with hollow interior and parallel graphitic planes along the tube walls. The apparent activation energies for CNT carpet growth on Fe and Fe–Cu catalysts are 0.71 and 0.54 eV, respectively. The synergistic effect of Fe and Cu show a strong dependence on the growth temperature, with Cu being more influential at temperatures higher than 450 °C. The low activation energies and long catalyst lifetimes observed are rationalized based on the unique composition of FTS-GP and Gibbs free energies for the decomposition reactions of the hydrocarbon components. The use of FTS-GP facilitates low-temperature growth of CNT carpets on traditional (alumina film) and nontraditional substrates (aluminum foil) and has the potential of enhancing CNT quality, catalyst lifetime, and scalability.
Market Planning in Agricultural Development: An Alaskan Example of How Not to Do It

Less developed countries (LDC) often suffer from development malaise caused by discrepancies between export dreams and development structures. A major economic activity of LDC’s is in many cases concerned with raw material development for export. Infrastructure development, an internal economic activity, is often ignored even though such an economic goal could enhance export of raw goods. Without internal development, LDC’s remain dependent on activities requiring little capital support, i.e., subsistence agriculture. If such countries are to gain economic independence, both external and internal development objectives must be met to reduce dependence on subsistence agriculture and raise the capacity of the nation for self-generating economic growth. A major problem is the coordination of the internal and external development policies so as not to seriously limit each other. In this respect, governments often attempt to facilitate both of these activities by acting as an employer and an administrator for a substantial range of marketing and infrastructural development programs.
Mitochondrial Myopathy and Congenital Cataract

The autosomal recessive syndrome characterized by mitochondrial myopathy of cardiac and skeletal muscle, congenital cataract and lactic acidosis is described in two forms following a retrospective study of 16 patients at the University of Nijmegen, The Netherlands.
Transport of arginine by an in vitro system.

Abstract Cell surface glycoproteins of Neurospora crassa conidia have been shown to bind amino acids and to be genetically associated with the previously defined amino acid transport systems of that organism. L-arginine does not readily permeate a film of Neurospora conidial lipids. Addition of glycoprotein extracts from Neurospora to the lipid film enhances permeation of arginine at an initial rate 1000 times the rate of permeation through lipid alone. The initial rate of passage exceeds the rate of unhindered passage (no lipid film) through the same cross sectional area by 10 fold.
West Side Story: The Journey to Lincoln Center Theater

Along with staging revivals of classic musicals such as Carousel and South Pacific, the Lincoln Center Theater (led by artistic director Andre Bishop and executive producer Bernard Gersten) has worked with contemporary American writers and composers such as Jason Robert Brown, Adam Guettel, and Michael John LaChiusa to produce new musicals that might otherwise be deemed not sufficiently commercial for Broadway.
The Concept of Telosponsivity: Answering an Unmet Need in Psychology

Abstract Psychologists have eschewed the description of behavior in terms of purpose, intention, or free will. The reason for this anti-teleological bias is traced to psychology's adoption of the natural science theoretical model, which dictates that no formal or final causation is to be employed in the description of events. The upshot is that a continuing theoretical bias has been institutionalized in psychology, one which distorts agential conceptions as used by people in everyday circumstances as well as by clinicians in psychodynamic contexts. To remedy this situation, the author proposes the adoption of a formal-final cause conception termed the telosponse . This construct defines behavior as enacted through the affirmation of a premised meaning, which is carried forward in precedent-sequacious fashion. Important foundation conceptions enabling a theorist to speak of telosponsivity include dialectical reasoning and tautological meaning extension.
Streptococcus pneumoniae capsular polysaccharide is linked to peptidoglycan via a direct glycosidic bond to β-D-N-acetylglucosamine

For many bacteria, including those important in pathogenesis, expression of a surface-localized capsular polysaccharide (CPS) can be critical for survival in host environments. In Gram-positive bacteria, CPS linkage is to either the cytoplasmic membrane or the cell wall. Despite the frequent occurrence and essentiality of these polymers, the exact nature of the cell wall linkage has not been described in any bacterial species. Using the Streptococcus pneumoniae serotype 2 CPS, which is synthesized by the widespread Wzy mechanism, we found that linkage occurs via the reducing end glucose of CPS and the β-D-N-acetylglucosamine (GlcNAc) residues of peptidoglycan (PG). Hydrofluoric acid resistance, 31P-NMR, and 32P labeling demonstrated the lack of phosphodiester bonds, which typically occur in PG-polysaccharide linkages. Component sugar analysis of purified CPS-PG identified only CPS and PG sugars in the appropriate ratios, suggesting the absence of an oligosaccharide linker. Time of flight mass spectrometry confirmed a direct glycosidic linkage between CPS and PG and showed that a single CPS repeat unit can be transferred to PG. The linkage was acetolysis susceptible, indicative of a 1,6 glycosidic bond between CPS and the GlcNAc C-6. The acetylation state of GlcNAc did not affect linkage. A direct glycosidic linkage to PG was also demonstrated for serotypes 8 and 31, whose reducing end sugars are glucose and galactose, respectively. These results provide the most detailed descriptions of CPS-PG linkages for any microorganism. Identification of the linkage is a first step toward identifying the linking enzyme and potential inhibitors of its activity.
Danger of Contamination of Water Supply when Water and Sewer Pipes are Close Together

A review of the present day water works practice shows that most of the faulty types of construction which have been responsible for water-borne epidemics are no longer used. However, certain types of construction through which a water supply may become contaminated are still commonly used. Among these is the laying of water and sewer pipe very near each other or in the same trench. It has been found in some sections that this arrangement of piping is more prevalent than is generally supposed. As more information becomes available showing that relatively high vacuums lasting over considerable periods of time are created in water mains, (see paper on Cross Connections with Public Water Supplies in the Journal of the American Water Works Association, 24: 11, page 1750, by S. B. Morris) the danger of this arrangement is apparent. There are three typical conditions of this problem which deserve study, i.e., 1. The laying of water pipe and sewer pipe parallel to each other in the same trench or in nearby trenches. 2. Water pipe and sewer pipe crossing each other at an angle, as at street intersections.
The adaptive complex method of global optimization with application to problems with discrete-continuous objective functions

Abstract The adaptive complex method of global optimization is presented along with an extension which makes it applicable to objective functions with both discrete and continuous decision variables. So called "discrete-continuous" objective functions are discussed and classified according to key subtypes. It is noted that such objective functions are inherently multimodal and that a number of optimization problems in manufacturing systems have socalled "discrete-continuous" objective functions. The extension of the adaptive complex method is described and it is seen to be effective in locating global optima with discretecontinuous objective functions. Results from applying this extended adaptive complex to a class of discrete-continuous objective functions are presented.
Not All Masks Are Created Equal: Masking Success in Clinical Trials of Children and Adolescents.

The current study assessed the success of masking omega-3 (Ω3) and psychotherapy in clinical trials of youth with depression or bipolar spectrum disorder. Participants were youth ages 7–14 with DSM-IV-TR diagnosed depressive (n = 72) or bipolar spectrum (n = 23) disorders. Inclusion diagnoses were depressive disorder, cyclothymic disorder, or bipolar disorder not otherwise specified. Exclusion diagnoses included bipolar I or II disorder, chronic medical condition or autism. Youth participated in 2 × 2 randomized controlled trials, in which they received Ω3 or placebo (PBO) and psychoeducational psychotherapy (PEP) or active monitoring (AM). Participants and study staff (including independent interviewers) were masked to Ω3/PBO allocation. Besides the masked independent interviewers, one coprincipal investigator (Co-PI) was fully masked to both conditions and completed all consensus conference ratings postrandomization. At the endpoint assessment or last completed interview, interviewers and the masked Co-...
Impaired Rhodopsin Generation in the Rat Model of Diabetic Retinopathy

Diabetic retinopathy is a common complication of diabetes mellitus. Diabetic patients experience functional deficits in dark adaptation, contrast sensitivity, and color perception before microvascular pathologies become apparent. Herein, we evaluated early changes in neural retinal function and in retinoid metabolism in the eye in diabetes. Streptozotocin-induced diabetic rats showed decreased a- and b-wave amplitudes of scotopic and photopic electroretinography responses 4 months after diabetes induction compared to nondiabetic controls. Although Western blot analysis revealed no difference in opsin expression, rhodopsin content was decreased in diabetic retinas, as shown by a difference in absorbance. Consistently, levels of 11-cis-retinal, the chromophore for visual pigments, were significantly lower in diabetic retinas compared to those in controls, suggesting a retinoid deficiency. Among visual cycle proteins, interphotoreceptor retinoid-binding protein and stimulated by retinoic acid 6 protein showed significantly lower levels in diabetic rats than those in nondiabetic controls. Similarly, serum levels of retinol-binding protein 4 and retinoids were significantly lower in diabetic rats. Overall, these results suggest that retinoid metabolism in the eye is impaired in type 1 diabetes, which leads to deficient generation of visual pigments and neural retinal dysfunction in early diabetes.
“The eye in the sky doesn’t lie”: Video replay and self-evaluations as part of the basic communication course

ABSTRACTThis study explores extent and frequency of conventional practices in the basic communication course: speeches, video replay, and self-evaluations from 45 basic course directors and instructors. Results indicated three to four speeches per curriculum, with two prominent speech types: informative (97.8%) and persuasive (91.1%). Approximately 76% of curriculums used video replay. Self-evaluation questions (N = 254) used 52.8% open, 40.6% closed, 21.9% circular, and 21.9% strategic questions. Most frequently used questions focused on: delivery (12.1%), content (10.6%), or delivery and content (11.1%). Findings suggest pedagogical practices vary across the discipline, and the discussion offers practical applications for improving practices.
Geolocation of Transmitters Using Minimally Accurate Receivers

The location of adversarial signals is of great importance to the military. Whether the enemy is jamming friendly communications or transmitting for other reasons, finding out where those signals are coming from may be the first goal of any response mission. If highly accurate direction-finding information is available, triangulation of the source can be trivial. The purpose of this paper is to analyze the possibilities for geolocation using substantially less accurate sources. We proceed using simulated receivers with high standard deviations relative to the possible values, and use simulations to demonstrate that geolocation is possible using a small number of such receivers.
How many subjects? Statistical power analysis in research

It is most satisfying to find a statistical book that is informative and mathematically rigorous, yet very pleasant reading in a manageable format. How Many Subjects?, by Helena Chmura Kraemer and Sue Thiemann, is just such a little gem. This stylishly slim volume (120 pages, of which 20 are chapter dividers or blanks) presents the authors' method of sample size estimation for a wide variety of statistical procedures, along with much useful instruction and many insights into general experimental design. Research investigators are increasingly being called upon to justify the number of observations required for their work (cf. the NIH Guide for the Care and Use of LaboratoryAnimals, Appendix D). Inaddition to obviating unnecessary distress to subjects, careful planning of experiments promotes economy and plain good science. Of the many sources of information on statistically appropriate sample size, many are task-specific, being limited to a single or small number of statistical procedures. Some are exhaustive and exhausting because of the mass and diversity of material. A regrettable few-unfortunately attractive to the beginner because of their simplicity-handle only Type I (0:) error and ignore the very important power side (Type II or I (3) of the sample size issue. Kraemer and Thiemann's book begins with a brief but lucid overview of the concepts of statistical hypothesis testing, critical effect size, and power analysis in the overall context of research study planning. A very elegant feature of the book is the authors' innovation of a single method of power calculation that is appropriate for a wide variety of different tests. Not only is this aesthetically
N-Methyl-D-Aspartate (NMDA) Receptors and the Kindling Model

This chapter will consider recent pharmacologic, electrophysiologic, and biochemical studies examining the role of a subtype of excitatory amino receptor, the NMDA receptor, in the development of kindling and expression of kindled seizures.
PHYSIOLOGY AND ENDOCRINOLOGY SYMPOSIUM: Factors influencing follicle development in gilts and sows and management strategies used to regulate growth for control of estrus and ovulation1

Factors that affect follicle health and growth can influence estrus, ovulation, conception, and litter size. Since the majority of the breeding herd is composed of sows, production schedules are established based on synchronized follicle growth following weaning. Insemination of sows over a 3- to 4-d period after weaning facilitates farrowing over fewer days and helps improve the uniformity of pigs at weaning. Synchronized inseminations of the group are reduced when disturbance to the follicular phase results in delayed estrus. The failure of >15 follicles to uniformly progress beyond the 6.0 mm size within 4 d during the follicular phase is associated with delayed estrus and ovulation, reduced ovulation rate, and reduced farrowing rate. In sows, the follicular phase is initiated at weaning by removal of the suckling inhibition, whereas in cycling gilts, luteolysis and clearance of progesterone begins the process. The timing and patterns of follicle-stimulating hormone and luteinizing hormone stimulation to the ovary determine follicle health and selection for ovulation. Interestingly, abnormal wean-to-estrus intervals in sows and deviations from a 19- to 22-d estrous cycle in gilts are associated with reduced fertility. However, in both cases, it is not entirely clear whether the abnormal intervals are a direct result of problems occurring prior to or only during the follicular phase. In prepubertal gilts, the signal for initiating the follicular phase remains elusive, but could reside in differential sensitivity and response to hormone signals at the level of the ovary and brain. Although the mechanisms are not clear, factors such as boar exposure, stress, feed intake, growth rate, and birthweight have been shown to stimulate an early follicular phase. In contrast, inhibitors to follicle growth have been associated with season, heat stress, photoperiod, negative energy balance, poor body condition, slow growth, fewer parities, and short lactation length. Hormonal aids for inducing and delaying the follicular phase, as well as for inducing ovulation are available to aid in synchronized breeding schedules.
The Revelation of Insider Attacks Through Two-Step Intrusion Revelation Algorithm

Big data stores a vast amount of data in the provider's infrastructure facility. The user is always reluctant in trusting a third party to save his/her sensitive information due to security concerns. There is a lack of focus on the leakage of confidential information by an insider. The work here is to detect these insider attack employing a two-step intrusion revelation algorithm and constructing a shielded communication channel for each of the processes to be executed in the system. In the first step, each of the processes passes through a controlled instruction sequence. The result of the chain is compared against the process stored in the duplicate nodes. Hence the system can be used to check the level of security in any big data workflow system.

Consensus without focus: Why news agenda setting expands the public agenda

Abstract Generating public consensus on issue priorities is one of the most important functions of news agenda setting. However, the nature of that consensus is not well understood. Agenda setting might build a public consensus focused on a limited set of priorities, but it also has potential to build a consensus that broadens the public’s issue agenda by generating shared concerns about problems beyond the bounds of personal experience. Evidence shows that from 1968–2010, broadcast news’ agenda-setting effect tended to broaden the public agenda rather than focus it. This tendency of news agenda setting to broaden the public agenda is not affected by the news agenda’s breadth or by which issues dominate the news, although issue-level agenda setting effects may, under some circumstances, focus the public agenda. If broadcast news does not focus the public agenda, it is unlikely a focused agenda will be generated by a more fragmented media ecology.

Fertility and pregnancy in systemic lupus erythematosus

Abstract Reproductive issues are an important aspect of systemic lupus erythematosus (SLE) patient care. While SLE itself does not increase the risk of infertility, prior exposure to cyclophosphamide, active disease, renal insufficiency, and advanced maternal age can contribute to difficulties conceiving. SLE patients can undergo assisted reproductive technologies as long as disease is under good control. During pregnancy, disease is more likely to flare in those with a history of renal disease and/or active disease in the 6 months preceding pregnancy. Preeclampsia and maternal morbidity are more common in SLE patients, and poor pregnancy outcomes such as preterm premature rupture of the membranes, small for gestational age infants, and fetal death are increased. Pregnancy loss is more frequent in those patients who have co-existing antiphospholipid syndrome. While not all medications can be used during pregnancy, hydroxychloroquine, glucocorticoids, and the immunosuppressives azathioprine, cyclosporine, and tacrolimus are compatible with pregnancy. We recommend that women with SLE take hydroxychloroquine and baby aspirin during pregnancy. Planning pregnancy during a time of disease quiescence on medications compatible with pregnancy and a multidisciplinary care team approach that includes rheumatology and maternal fetal medicine can lead to good pregnancy outcomes in most SLE patients.
Measuring More Than Exposure: Does Stress Appraisal Matter for Black-White Differences in Anxiety and Depressive Symptoms Among Older Adults?

Background and Objectives Prior research and theory suggest that exposure to objectively stressful events contributes to mental health disparities. Yet, blacks report higher cumulative stress exposure than whites but lower levels of common psychiatric disorders. In order to understand why blacks bear disproportionate stress exposure but similar or better mental health relative to whites, we need to consider race differences in not only stress exposure, but also stress appraisal-how upsetting stress exposures are perceived to be. Research Design and Methods We examine whether race differences in the number of reported chronic stressors across 5 domains (health, financial, residential, relationship, and caregiving) and their appraised stressfulness explain black-white differences in anxiety and depressive symptoms. Data come from 6019 adults aged older than 52 from the 2006 Health and Retirement Study. Results Older blacks in this sample experience greater exposure to chronic stressors but appraise stressors as less upsetting relative to whites. In fully adjusted models, stress exposure is related to higher levels of anxiety and depressive symptoms, and perceiving stress as upsetting is associated with higher symptomology for whites and blacks. We also find that blacks report greater anxiety symptoms but fewer depressive symptoms with more stress exposure relative to whites. Stress appraisal partially explains race differences in the association between stress exposure and anxiety symptoms and fully explains race differences in the association between exposure and depressive symptoms. Discussion and Implications The relationship between race, chronic stress exposure, and mental health is mediated by stress appraisal. Stress appraisal provides insight on important pathways contributing to black-white mental health disparities in older adulthood.
IS SELF-CONCEPT ON RESILIENCE AND HAPPINESS ASSOCIATED? A STUDY OF THE UNDERGRADUATE STUDENTS IN NIGERIA

happiness among male and female undergraduate students in a Nigerian college. The study was conducted using the cross-sectional methodology. The sample size was 70 students conveniently recruited for sampling purpose. The results show that happiness and resilience are statistically significant between male and female students; whereas, self-concept is statistically insignificant between male and female students. Furthermore, the results show that self-concept and happiness have positive and significant correlation; whereas, the relationship between self-concept and resilience is positive but insignificant. Similarly, the relationship between resilience and happiness is positive but insignificant.
NICU and postpartum nurse perspectives on involving fathers in newborn care: a qualitative study.

Perinatal care nurses are well positioned to provide the education and support new fathers need to navigate the transition to fatherhood and to encourage positive father involvement from the earliest hours of a child’s life. To effectively serve fathers in perinatal settings, it is important to understand the attitudes, beliefs, and behaviors of healthcare providers that may encourage and engage them, or alternatively alienate and discourage them. This qualitative study involved structured interviews with ten NICU and postpartum nurses from hospitals in two large Texas cities. The interview protocol was designed to elicit descriptive information about nurses’ attitudes and beliefs, sense of efficacy and intention for working with fathers, as well as their father-directed behaviors. Nurses were recruited for the study using a purposive sampling approach. Interviews were conducted by telephone and lasted approximately 25 to 35 min. Data were analyzed using a qualitative descriptive approach. Overall, study participants held very positive subjective attitudes toward fathers and father involvement. Nevertheless, many of the nurses signaled normative beliefs based on race/ethnicity, gender, and culture that may moderate their intention to engage with fathers. Participants also indicated that their education as well as the culture of perinatal healthcare are focused almost entirely on the mother-baby dyad. In line with this focus on mothers, participants comments reflected a normative belief that fathers are secondary caregivers to their newborns, there to help when the mother is unavailable. Nurse attitudes and practices that place mothers in the role of primary caregiver may be interpreted by fathers as excluding or disregarding them. Further research is needed to validate the results of this small-scale study, and to assess whether and how provider attitudes impact their practices in educating and engaging fathers in newborn care.
Machine Learning Predicts Femoral and Tibial Implant Size Mismatch for Total Knee Arthroplasty.

Abstract Background Despite reasonable accuracy with preoperative templating, the search for an optimal planning tool remains an unsolved dilemma. The purpose of the present study was to apply machine learning (ML) using preoperative demographic variables to predict mismatch between templating and final component size in primary total knee arthroplasty (TKA) cases. Methods This was a retrospective case-control study of primary TKA patients between September 2012 and April 2018. The primary outcome was mismatch between the templated and final implanted component sizes extracted from the operative database. The secondary outcome was mismatch categorized as undersized and oversized. Five supervised ML algorithms were trained using 6 demographic features. Prediction accuracies were obtained as a metric of performance for binary mismatch (yes/no) and multilevel (undersized/correct/oversized) classifications. Results A total of 1801 patients were included. For binary classification, the best-performing algorithm for predicting femoral and tibial mismatch was the stochastic gradient boosting model (area under the curve: 0.76/0.72, calibration intercepts: 0.05/0.05, calibration slopes: 0.55/0.7, and Brier scores: 0.20/0.21). For multiclass classification, the best-performing algorithms had accuracies of 83.9% and 82.9% for predicting the concordance/mismatch of the femoral and tibial implant, respectively. Model predictions of greater than 51.0% and 47.9% represented high-risk thresholds for femoral and tibial sizing mismatch, respectively. Conclusions ML algorithms predicted templating mismatch with good accuracy. External validation is necessary to confirm the performance and reliability of these algorithms. Predicting sizing mismatch is the first step in using ML to aid in the prediction of final TKA component sizes. Further studies to optimize parameters and predictions for the algorithms are ongoing.
The rise of big U.S. banks and the fall of big European banks: A statistical decomposition

Abstract Bank asset concentration has risen in the U.S. since the 1980s and declined in Europe since 2008. We decompose this rise and fall of big banks using rank-based empirical methods that characterize dynamic power law distributions into two shaping factors: the growth rates and idiosyncratic volatilities of assets for different size-ranked banks. Higher relative growth rates for the largest U.S. banks led to greater asset concentration. Idiosyncratic volatilities for U.S. banks declined, resulting in lower fundamental volatility of bank assets — the aggregate volatility due to idiosyncratic, bank-specific shocks — despite the rise in concentration since the 1990s. In contrast, the relative growth rates for the largest European banks declined and this led to the lower concentration of European bank assets. Over this same time period, the idiosyncratic volatilities and fundamental volatility of European bank assets have been stable.
Does the order of presentation of extrinsic and intrinsic quality attributes matter when eliciting willingness to pay

In this study, we estimate consumers' willingness to pay (WTP) for ready meals preserved using microwave assisted pasteurization systems (MAPS)-a novel pasteurization technology, compared to frozen, ready meals. We conducted a laboratory multi-round experimental auction for two samples of ready meal jambalaya in which appearance and sensory evaluation along with extrinsic information was sequentially disclosed to panelists. Our results suggest that when participants tasted the meals and formed an opinion from the meal itself, the liking of appearance and sensory attributes were the most impactful factors for participants' WTP regardless of other available extrinsic (name of the preservation technology and environmental impacts of each technology) attributes. The words "microwave" and "pasteurization" did not negatively impact the WTP. The order in which intrinsic and extrinsic attributes were evaluated and presented did not impact absolute WTP values, but the order did impact the weight of each attribute type on the WTP. PRACTICAL APPLICATION: The sensory perceptions had a larger effect than the name of the preservation technology and environmental impacts on the willingness to pay (WTP) for ready meals. The order of presented information to panelists did not impact absolute values of WTP. The words "microwave" and "pasteurization" did not have a negative effect on WTP.
Global Trends in Cancer Nanotechnology: A Qualitative Scientific Mapping Using Content-Based and Bibliometric Features for Machine Learning Text Classification

This study presents a new way to investigate comprehensive trends in cancer nanotechnology research in different countries, institutions, and journals providing critical insights to prevention, diagnosis, and therapy. This paper applied the qualitative method of bibliometric analysis on cancer nanotechnology using the PubMed database during the years 2000–2021. Inspired by hybrid medical models and content-based and bibliometric features for machine learning models, our results show cancer nanotechnology studies have expanded exponentially since 2010. The highest production of articles in cancer nanotechnology is mainly from US institutions, with several countries, notably the USA, China, the UK, India, and Iran as concentrated focal points as centers of cancer nanotechnology research, especially in the last five years. The analysis shows the greatest overlap between nanotechnology and DNA, RNA, iron oxide or mesoporous silica, breast cancer, and cancer diagnosis and cancer treatment. Moreover, more than 50% of the information related to the keywords, authors, institutions, journals, and countries are considerably investigated in the form of publications from the top 100 journals. This study has the potential to provide past and current lines of research that can unmask comprehensive trends in cancer nanotechnology, key research topics, or the most productive countries and authors in the field.
Investigating Quality Perceptions of Foreign Services by Chinese Consumers

Consumers are known to use the country-of-origin (COO) of a product to infer the quality of products. Products of technologically advanced countries such as the US and Germany are known to enjoy positive country-of-origin effects. Conversely, products made in the developing countries typically suffer from negative COO effect. While this influence of COO is widely recognized for products, the same cannot be said about services. Only a handful of studies have empirically investigated the relationship between COO and perceived service quality. Additionally, most of these studies in this research paradigm, are undertaken in industrialized countries; hence their findings cannot be extrapolated to the newly industrialized countries (NIC) that offer tremendous market potential for global services. It has, therefore, become imperative for multinational companies to understand if and how consumers in the major NICs use COO and other cues to infer service quality. Using data collected from consumers in Beijing in the Peoples Republic of China, we demonstrate significant COO effect on two service categories: hotels and restaurants. We also highlight how these research findings will help managerial decisions about pricing and promotion.
Ethical Considerations in Global Heart Surgery

Consideration of the ethical questions that arise in the context of global cardiac surgery can help us to more readily recognize and avoid obstacles to collaborative work and program development. One question that often arises concerns whether and when scarce resources should be allocated to heart surgery, which may seem expensive relative to other interventions. The growing recognition of the excess worldwide mortality that is associated with heart disease and other noncommunicable diseases, in combination with data based on cost effectiveness analysis, can form the scientific basis on which we can build an ethical evaluation of just resource allocation. Once a decision has made to invest in program establishment, ethical guidelines recently established by cardiothoracic surgical organizations can help navigate the working relationships between all stakeholders. These guidelines emphasize responsibilities toward the patients first, of course, but also include those toward local providers, volunteers, donors and other payors. Because establishment of sustainable programs is key to achieving a long term solution, teaching and mentoring local providers, and helping them to succeed, should almost always be the intentional focus of cardiothoracic global health initiatives, and visitors should attempt to avoid being perceived or presented as the “experts” or “heroes” to the detriment of the local health care team. Finally, differences in values and norms, particularly but not only regarding questions of end-of-life care, should be identified and discussed early, openly, and often, rather than being left to a moment of crisis.
Perovskite and Related Structure Systems

Perovskite and perovskite-related structures are important crystallographic structures particularly for oxide functional materials because most of the newly discovered functional materials belong to this category (for a complete list of perovskite structures, see Galasso, 1969, 1990). Typical perovskite materials of technological interests are piezoelectric Pb(Zr,Ti)O3, electrostrictive Pb(Mg,Nb)O3, and magnetoresistance (La,Ca)MnO3. There is much interest in exploiting the mystery of the perovskite structure and its family for understanding the functionality of materials, such as superconductivity, ferromagnetism, ferroelectricity, magnetoresistance, ionic conductivity, and dielectricity. Therefore, understanding perovskite and related structures is essential for research in functional materials because it could lead to discovering new materials with superior properties and unique functionality.
Lower Leg Injury Reference Values and Risk Curves from Survival Analysis for Male and Female Dummies: Meta-analysis of Postmortem Human Subject Tests.

Objective: Derive lower leg injury risk functions using survival analysis and determine injury reference values (IRV) applicable to human mid-size male and small-size female anthropometries by conducting a meta-analysis of experimental data from different studies under axial impact loading to the foot–ankle–leg complex.Methods: Specimen-specific dynamic peak force, age, total body mass, and injury data were obtained from tests conducted by applying the external load to the dorsal surface of the foot of postmortem human subject (PMHS) foot–ankle–leg preparations. Calcaneus and/or tibia injuries, alone or in combination and with/without involvement of adjacent articular complexes, were included in the injury group. Injury and noninjury tests were included. Maximum axial loads recorded by a load cell attached to the proximal end of the preparation were used. Data were analyzed by treating force as the primary variable. Age was considered as the covariate. Data were censored based on the number of tests condu...
Representations of the Cinaedus in Roman Art: Evidence of "Gay" subculture?

Whereas analysis of ancient Roman texts reveals signs of a possible homosexual subculture, their interpretation is difficult. This article analyzes the content and context of visual representations of male-male intercourse, including wall paintings at Pompeii, a silver cup, and an engraved agate gemstone. Whether presenting negative stereotypes (Tavern of Salvius, Pompeii; Suburban Baths, Pompeii), or positive ones (Warren Cup, British Museum; Leiden gemstone), these representations reveal the presence of well-developed social attitudes toward the practice ofmale-male sex and the practitioners themselves.
Turn-of-the-Century Dependence and Interdependence: Roles of Teens in Family Economies of the Aged

This study adopts a household economy framework of analysis and links county, household, and individual level 1910 Census data to explore the extra-household activities of teens living in household economies of the aged. Findings are that the household presence of elder household heads or nonnuclear elders (coresident kin of household heads) had significant but different impacts on teens. Older household heads participated less in paid employment and responsibility for economic support generally fell on male teens in the household. Teens were less likely to attend school. In contrast, the presence of nonnuclear elders in households increased the odds of teen members being in school. Nonnuclear elders, as a group, showed need across several dimensions: economic, health, and social support, yet their intrahousehold contributions appear to have allowed teens to pursue schooling.
Improved MODIS aerosol retrieval over urban scenes

Determination of aerosol optical depth from satellite remote sensing measurements is extremely complex due to the large variability of aerosol optical properties. Significant simplification occurs when measurements are taken over water since the ocean reflection signal can be taken as negligible in the NIR. Unfortunately, over land, most of the signal can be attributed to ground reflectance. While conventional approaches look for "dark" pixels in an image to isolate aerosols, these pixels are subjected to increased noise. In this paper, we focus on the feasibility of the MODIS sensor to determine aerosol optical depth. In particular, an intercomparison between MODIS and CIMEL shows a significant trend for MODIS to overestimate optical depth. We show that this may be explained through an inaccurate assumption on the correlation between the VIS and NIR surface albedos. In particular, we show through an analysis of hyperspectral high resolution Hyperion data that the correlation coefficient assumption underestimates ground albedo resulting in an overestimate of the VIS optical depth. Using a series of coincident measurements between aeronet and MODIS, we estimate a more accurate angle dependant albedo and use it to determine aerosol optical depth. The results show significantly less overbias. Our efforts to reduce space resolution to 1.5km are also discussed.
Digestive efficiency of the chaetognath Sagitta hispida Conant

Abstract A technique is described whereby the digestive efficiency of a plankton carnivore, Sagitta hispida Conant, which tends to feed infrequently on relatively large food organisms, was determined gravimetrically. The mean digestive efficiency in 24 experiments was 80 % (82 % on an ash-free basis) which was not affected by the size of the food organism or pre-starvation period. Since the chaetognath assimilated variable quantities of the inorganic fraction of its food (mean 43 %) calculations of digestive efficiency by Conover's ‘ratio’ method underestimated the true values.
Remote monitoring of ICDs and CRTs

Cardiac implantable electronic devices are increasing in prevalence and functionality. Post-implant follow-up is important for monitoring both device function and patient condition. However, practice is inconsistent. For example, ICD follow-up schedules vary from 3 months to yearly according to facility and physician preference and availability of resources. Recommended follow-up schedules impose significant burden. Importantly, no surveillance occurs between follow-up visits. In contrast, implantable devices with automatic remote monitoring capability provide a means for performing constant surveillance, with the ability to identify salient problems rapidly. Results from large randomized prospective trials of all types of CIEDs from different manufacturers, and conducted in different countries, consistently indicate superior performance to conventional care for achieving the current follow-up goals of patient retention and early problem discovery, improving patient safety and convenience, yet promoting clinic efficiencies. Thus, automatic remote home monitoring is a transforming technology in the evolution of CIEDs, and is poised for remarkable gains in disease management.
Ontology Development and Evolution in the Accident Investigation Domain

InvestigationOrganizer (IO) is a collaborative semantic Web application designed to support mishap investigations, and has been used for accidents ranging from those involving only minor property damage to the loss of the Space Shuttle Columbia. The development and use of IO in support of these investigations has provided significant lessons about the use of semantic Web technologies in real-world systems. IO is a data and knowledge repository for a wide range of mishap related information in which investigators meaningfully structure information and link together evidence, causal models, and investigation results. The types of knowledge that investigators can include in the repository are defined by its investigation ontology, a component of the system that expresses investigation concepts using a logical formalism. IO developers can dynamically alter this ontology without having to recompile the application. This paper describes the development of the investigation ontology for IO, focusing on its growth in response to user needs during the investigations, as well as efforts to control that growth
