The Complex Bingham Distribution and Shape Analysis

SUMMARY A complex version of the Bingham distribution is defined on the unit complex sphere in Ck. Various statistical properties, including asymptotic normality under high concentration, are derived. Symmetries in the distribution make it a natural tool for the analysis of the shape of landmark data in two dimensions. Strengths and weaknesses of this approach are investigated. Links and contrasts with Bookstein co-ordinates are discussed. A hybrid approach to principal component analysis based on complex and real co-ordinates is suggested.
Clinical for Inflammatory Syndrome in Children Associated With and in

Objective: To provide guidance on the management of Multisystem Inflammatory Syndrome in Children (MIS-C), a condition characterized by fever, inflammation, and multiorgan dysfunction that manifests late in the course of SARS-CoV-2 infection. The Task Force also provided recommendations for children with hyperinflammation during COVID-19, the acute, infectious phase of SARS-CoV-2 infection. Methods: The Task Force was composed of 9 pediatric rheumatologists, 2 adult rheumatologists, 2 pediatric cardiologists, 2 pediatric infectious disease specialists, and 1 pediatric critical care physician. Preliminary statements addressing clinical questions related to MIS-C and hyperinflammation in COVID-19 were developed based on evidence reports. Consensus was built through a modified Delphi process that involved 2 rounds of anonymous voting and 2 webinars. A 9-point scale was used to determine the appropriateness of each statement (1-3, inappropriate; 4-6, uncertain; 7-9, appropriate), and consensus was rated as low (L), moderate (M), or high (H) based on dispersion of the votes along the numeric scale. Approved guidance statements had to be classified as appropriate with moderate or high levels of consensus, which were pre-specified prior to voting. Results: A total of 128 statements were approved by the Task Force, which were refined into 40 final guidance statements accompanied by a flow diagram depicting the diagnostic pathway for MIS-C. Conclusion: Our understanding of SARS-CoV-2-related syndromes in the pediatric population continues to evolve. This guidance document reflects currently available evidence coupled with expert opinion but is meant to be modified as additional data become available. balance of risks and benefits suggests anakinra as first-line immunomodulatory treatment of children with COVID-19 and hyperinflammation. There is insufficient evidence to support the use of other immunomodulatory agents unless glucocorticoids, IL-1 blocking, and/or IL-6 blocking therapies are contraindicated or have failed.
A RANDOM FIXED POINT THEOREM FOR MULTIVALUED NONEXPANSIVE OPERATORS

Let (ii, Z) be a measurable space with Z a sigma-algebra of subsets of il, and let C be a nonempty, bounded, closed, convex, and separable subset of a uniformly convex Banach space X. It is shown that every multivalued nonexpansive random operator T: Q x C —> K(C) has a random fixed point, where K(C) is the family of all nonempty compact subsets of C endowed with the Hausdorff metric induced by the norm of X . The purpose of this note is to prove the random version of the following celebrated deterministic result due to Lim [12]. Theorem L [12]. Let X be a uniformly convex Banach space, let C be a nonempty, bounded, closed, convex subset of X, and let K(C) be the collection of all nonempty compact subsets of C endowed with the Hausdorff metric. Then every multivalued nonexpansive mapping T: C -* K(C) has a fixed point. We begin with establishing some preliminaries. By (fi, X) we denote a measurable space with E a sigma-algebra of subsets of fi. Let (X, d) be a metric space. Then we denote by K(X) the family of all nonempty compact subsets of X and by H the Hausdorff metric on K(X) induced by the metric d of X; that is, for A, B in K(X), H(A, B) = max < sup d(a, B), sup d(b, A) > , laeA beB J where d(x, E) is the distance from a point x e X to a subset E c X, i.e., d(x, E) = inf{d(x, y): y e E}. Recall that a multivalued mapping T: X -+ K(X) is said to be nonexpansive if H(Tx,Ty)<d(x,y) for all x, y in X and that a point x in X is said to be a fixed point of T if x e Tx. A multivalued operator /: fi —► X is said to be (X-)measurable if, for any open subset B of X, f~x (B) = {co e fi: f(co) n B ^ 0} e Z.

Three Stream Graph Attention Network using Dynamic Patch Selection for the classification of micro-expressions

To understand the genuine emotions expressed by humans during social interactions, it is necessary to recognize the subtle changes on the face (micro-expressions) demonstrated by an individual. Facial micro-expressions are brief, rapid, spontaneous gestures and non-voluntary facial muscle movements beneath the skin. Therefore, it is a challenging task to classify facial micro-expressions. This paper presents an end-to-end novel three-stream graph attention network model to capture the subtle changes on the face and recognize micro-expressions (MEs) by exploiting the relationship between optical flow magnitude, optical flow direction, and the node locations features. A facial graph representational structure is used to extract the spatial and temporal information using the three frames. The varying dynamic patch size of optical flow features is used to extract the local texture information across each landmark point. The network only utilizes the landmark points location features and optical flow information across these points and generates good results for the classification of MEs. A comprehensive evaluation of SAMM and the CASME II datasets demonstrates the high efficacy, efficiency, and generalizability of the proposed approach and achieves better results than the state-of-the-art methods.

Moving Photovoltaic Installations: Impacts of the Sampling Rate on Maximum Power Point Tracking Algorithms

This paper investigates the impact of the solar radiation level on the available output power of moving photovoltaic (PV) installations with the help of PV simulation models and real-world environmental data. For moving PV installations, for example, on top of hybrid electric vehicles and battery-powered electric vehicles, the sampling rate was 6000 samples per second. We analyze the changes in the amount of solar radiation that can influence on the control of the operating voltage of PVs within maximum power point tracking (MPPT) algorithms. We present recommendations for the sampling rate of environmental data, which is used for PV simulation models. Furthermore, we discuss the update frequency of vital parameters of different MPPT techniques for controlling moving PV installations. Here, we concentrate on the degree of efficiency of the perturb and observe algorithm. In addition, we show how the sampling rate of environmental data influences the test criteria for MPPT algorithms.
Prevalence of Diarrhoeal Diseases among Under-Five Paediatric Patients in a Tertiary Health Care Facility, South Eastern Nigeria: A 5-Year Review

Background: Diarrhoeal disease remains a major cause of morbidity and mortality in children, especially in developing countries. Although Nigeria has already achieved remarkable progress in reducing under-five mortality in the last decades, studies done in different parts of Nigeria had shown that diarrhoea is still a major public health problem. Objectives: This study aimed at determining the prevalence of diarrhoea in under-five children who presented to Nnamdi Azikiwe University Teaching Hospital Neni through the period of January 2016 - December 2020, a 5-year review. It is also aimed at noting the influence of other socio demographic factors such as age, sex and seasonal variation on the occurrence of diarrhoeal diseases. Methods: A retrospective study design was used as patients’ records were obtained from the medical records for the said duration of study and a pro forma was used in extracting needed information. Results: A total of 128 cases of diarrhoeal disease were recorded out of the 897 under-five aged children that visited the hospital at the said period of study. Thus with a prevalence of 14.27%. Higher number of cases were recorded in the dry season 96 (75.0%) than the wet season; 32 (25.0%) cases. More males were affected; 78(60.1%) than females;50 (39.1%). Children aged 0-11 months were affected more; 62 (48.4%) followed by those within the age bracket of 12-23 months 32(25.0%) with those within the ages 48-59months having the least number of cases; 8 (6.3%). Conclusions: From the study it was concluded that diarrhoea occurs more in the dry season in this region than in the wet season. It was also concluded that the general risk of diarrhoeal disease decreases with increasing age in children and toddlers are the most at risk group of suffering the disease.
Increased Skeletal Muscle TNF- α and Impaired Insulin Signaling Persists in Obese GDM Women 1 Year Postpartum

Objective . Women with GDM demonstrate chronic and progressive insulin resistance and a markedly increased risk of converting to type 2 diabetes after pregnancy, however the cellular mechanisms underlying this insulin resistance is unknown. Research Design and Methods . We investigated the progression of insulin resistance in nine obese women with GDM during late pregnancy (30-36 weeks) and 1 year postpartum. Skeletal muscle biopsies were obtained at each visit and insulin resistance was determined by hyperinsulinemic-euglycemic clamp technique. Results . Insulin resistance was not significantly improved in GDM women (4.1±0.4 vs. 5.8±1.1 10 -2 mg·kgFFM·min -1 /µU·ml -1 ). Subjects did not experience significant weight loss postpartum. Body weight, fat mass, fasting glucose and plasma TNF- α remained higher 1 year postpartum compared to women with NGT studied previously. Skeletal muscle TNF- α mRNA was elevated 5 to 6-fold in GDM women, and remained higher 1 year postpartum. While levels of IR, IRS-1 and p85 α improved postpartum, insulin-stimulated IR tyrosine phosphorylation and receptor tyrosine kinase activity did not significantly improve postpartum in GDM. The levels of 312 Ser-IRS-1 also did not improve postpartum and correlated with TNF- α mRNA (r 2 =0.19, P <0.03), consistent with a state of sub-clinical inflammation and chronic skeletal muscle insulin resistance. Conclusions . These results suggest the mechanisms underlying chronic insulin resistance in GDM women may be driven by increased inflammation that impinges on the IR and IRS-1 signaling cascade in skeletal muscle. These findings have important implications for the health of GDM women during subsequent pregnancies as well as the risk for progression to type 2 diabetes. phosphoinositide 3-kinase.
A Comparative Evaluation of the Efficacy of Disinfectants on Patient Derived Irreversible Hydrocolloid Impressions and their Effect on the Dimensional Accuracy of the Impression Material

Purpose: Assessing the efficacy of disinfectants on irreversible hydrocolloid impressions and their effect on the dimensional accuracy. Materials and Methods: The study was carried out to compare the efficacy of three commercially available disinfectants (Cidex – 2% Glutaraldehyde (Johnson & Johnson), 1% Sodium Hypochlorite (I - Dent), MD 520 – 0.5% Glutaraldehyde and 0.25% Ammonium chloride (Durr)) in eliminating or reducing the microbial colonies on patient derived irreversible hydrocolloid impressions and the resultant effect on the dimensional accuracy of the impression material when exposed to these agents. Results: MD 520 system resulted in maximum (95.6%) removal of the visible colonies for all samples investigated and 1% sodium hypochlorite was found to cause the least amount of dimensional changes in irreversible hydrocolloid impressions. Conclusions: It is entirely the clinician’s choice to select disinfecting agents to use considering all their advantages and disadvantages. It should be kept in mind that though MD 520 was shown to be the most effective disinfectant, sodium hypochlorite caused lesser dimensional changes in the alginate impressions. solutions and how effective are the disinfection procedures [2]. Very few studies have been undertaken till date which reveals answers to all these aspects together. Meanwhile, manufacturers claim disinfectants are better for disinfection of irreversible hydrocolloid impressions, but they do not mention about the dimensional accuracy of the impression. The idea behind conceptualizing this study was the fulfillment of the following objectives: (1) To clinically examine the carriage of oral pathogens on the impression surface. (2) To clinically evaluate the disinfection efficacy of three commercially available agents in removing oral pathogens from patient derived impressions. (3) To evaluate the effect of these disinfecting agents on the dimensional stability of irreversible hydrocolloid impressions.
The role of FOXO transcription factors in the development of type 2 diabetes and related potential therapeutic possibilities

Forkhead box class O (FOXO) family member proteins are key transcription factors for maintaining the intracellular homeostasis in response to changes in the internal and external environment. They participate in the control of such cellular processes as proliferation, cell cycle, apoptosis, glucose and lipid metabolism, and oxidative stress response. Altered expression and activity of these factors are associated with development of metabolic disturbances, primarily type 2 diabetes. Understanding of the role of FOXO in the pathophysiology of these abnormalities will enable appropriate steps to prevent their development and to create therapies targeted at the disturbances underlying type 2 diabetes and metabolic syndrome. In the present article, we summarized the current knowledge about the physiology and pathophysiology of these transcription factors and described their role in the development of diabetes and functioning of various organs. We focused on their role in progression of diabetes and indicated potential targets for future therapeutic interventions. (clin Diabetol 2021; 10)

Higher Viral Load Drives Infrequent Severe Acute Respiratory Syndrome Coronavirus 2 Transmission Between Asymptomatic Residence Hall Roommates

Background: The coronavirus disease 2019 pandemic spread to >200 countries in <6 months. To understand coronavirus spread, determining transmission rate and defining factors that increase transmission risk are essential. Most cases are asymptomatic, but people with asymptomatic infection have viral loads indistinguishable from those in symptomatic people, and they do transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, asymptomatic cases are often undetected. Methods: Given high residence hall student density, the University of Colorado Boulder established a mandatory weekly screening test program. We analyzed longitudinal data from 6408 students and identified 116 likely transmission events in which a second roommate tested positive within 14 days of the index roommate. Results: Although the infection rate was lower in single-occupancy rooms (10%) than in multiple-occupancy rooms (19%), interroommate transmission occurred only about 20% of the time. Cases were usually asymptomatic at the time of detection. Notably, individuals who likely transmitted had an average viral load approximately 6.5-fold higher than individuals who did not (mean quantification cycle [C q ], 26.2 vs 28.9). Although students with diagnosed SARS-CoV-2 infection moved to isolation rooms, there was no difference in time to isolation between cases with or without interroommate transmission. Conclusions: This analysis argues that interroommate transmission occurs infrequently in residence halls and provides strong correlative evidence that viral load is proportional to transmission probability.
isoforms in proximal and distal human airways

Expression of the Na 1 /H 1 and Cl 2 / HCO 3 2 exchanger isoforms in proximal and distal human airways. Am. J. Physiol. 276 ( Lung Cell. Mol. Physiol. 20): L971–L978, 1999. —Recent studies have indicated the presence of Na 1 /H 1 and Cl 2 /HCO 3 2 exchange activities in lung alveolar and tracheal tissues of various species. To date, the identity of the Na 1 /H 1 (NHE) and Cl 2 /HCO 3 2 (AE) exchanger isoforms and their regional distribution in human airways are not known. Molecular species of the NHE and AE gene families and their relative abundance in the human airway regions were assessed utilizing RT-PCR and the RNase protection assay, respectively. Organ donor lung epithelia from various bronchial regions (small, medium, and large bronchi and trachea) were harvested for RNA extraction. Gene-speciﬁc primers for the human NHE and AE isoforms were utilized for RT-PCR. Our results demonstrated that NHE1, AE2, and brain AE3 isoforms were expressed in all regions of the human airways, whereas NHE2, NHE3, AE1, and cardiac AE3 were not detected. RNase protection studies for NHE1 and AE2, utilizing glyceraldehyde-3-phosphate dehydrogenase as an internal standard, demonstrated that there were regional differences in the NHE1 mRNA levels in human airways. In contrast, the levels of AE2 mRNA remained unchanged. Differential expression of these isoforms in the human airways may have functional signiﬁcance related to the airway absorption and secretion of electrolytes. probes were synthesized utilizing higher template amounts of cold GAPDH compared with NHE1 or AE2 (ratio of 5:1). Also, cold CTP ratio to 32 P-labeled CTP was 4:1 for GAPDH versus NHE1 or AE2. This was speciﬁcally done to synthesize a lower speciﬁc activity 32 P-labeled GAPDH probe compared with NHE1 or AE2 to keep the density of GAPDH in a readable range on ﬁnal autoradiograms while still enabling the detection of NHE1 and AE2 isoforms. This procedure of labeling was exactly the same each time, and once the probes were synthesized, the same batch of probes was simultaneously utilized for hybridization with equal amounts of RNA extracted from small, medium, and large bronchi and trachea.
Mobile Payments, Demographics and Firm Performance in Kenya

Technological advancements have presented firms with an opportunity to use mobile payments to enhance their performance. This study explores the relationship between mobile payments and firm performance in Kenya. The moderating effects of demographics are also studied. Using primary data collected from 289 supermarkets based in Nairobi City County, we determine whether the use of mobile payment has enhanced firm performance as defined by profitability, operation costs, revenues and the number of customers served. Empirical results from logit regression analysis reveal that the use of a mobile to make payments in supermarkets directly impacts the performance of supermarkets. Additionally, consumer characteristics have a significant moderating effect on the relationship between mobile payments and profitability of supermarkets. We conclude that the use of mobiles to make payments in supermarkets in Kenya has acquired the requisite critical mass level to be in a position to influence revenues of these firms.
