Experiences of Home Health Care Workers in New York City During the Coronavirus Disease 2019 Pandemic: A Qualitative Analysis.

Importance Home health care workers care for community-dwelling adults and play an important role in supporting patients with confirmed and suspected coronavirus disease 2019 (COVID-19) who remain at home. These workers are mostly middle-aged women and racial/ethnic minorities who typically earn low wages. Despite being integral to patient care, these workers are often neglected by the medical community and society at large; thus, developing a health care system capable of addressing the COVID-19 crisis and future pandemics requires a better understanding of the experiences of home health care workers. Objective To understand the experiences of home health care workers caring for patients in New York City during the COVID-19 pandemic. Design, Setting, and Participants From March to April 2020, a qualitative study with 1-to-1 semistructured interviews of 33 home health care workers in New York City was conducted in partnership with the 1199SEIU Home Care Industry Education Fund, a benefit fund of the 1199 Service Employees International Union United Healthcare Workers East, the largest health care union in the US. Purposeful sampling was used to identify and recruit home health care workers. Main Outcomes and Measures Audio-recorded interviews were professionally transcribed and analyzed using grounded theory. Major themes and subthemes were identified. Results In total, 33 home health care workers employed by 24 unique home care agencies across the 5 boroughs of New York City participated. Participants had a mean (SD) age of 47.6 (14.0) years, 32 (97%) were women, 21 (64%) were Black participants, and 6 (18%) were Hispanic participants. Five major themes emerged: home health care workers (1) were on the front lines of the COVID-19 pandemic but felt invisible; (2) reported a heightened risk for virus transmission; (3) received varying amounts of information, supplies, and training from their home care agencies; (4) relied on nonagency alternatives for support, including information and supplies; and (5) were forced to make difficult trade-offs in their work and personal lives. Conclusions and Relevance In this qualitative analysis, home health care workers reported providing frontline essential care, often at personal risk, during the COVID-19 pandemic. They experienced challenges that exacerbated the inequities they face as a marginalized workforce. Interventions and policies to better support these frontline health care professionals are urgently needed.
Fgfbp1 promotes blood-brain barrier development by regulating collagen IV deposition and maintaining Wnt/β-catenin signaling

ABSTRACT Central nervous system (CNS) blood vessels contain a functional blood-brain barrier (BBB) that is necessary for neuronal survival and activity. Although Wnt/β-catenin signaling is essential for BBB development, its downstream targets within the neurovasculature remain poorly understood. To identify targets of Wnt/β-catenin signaling underlying BBB maturation, we performed a microarray analysis that identified Fgfbp1 as a novel Wnt/β-catenin-regulated gene in mouse brain endothelial cells (mBECs). Fgfbp1 is expressed in the CNS endothelium and secreted into the vascular basement membrane during BBB formation. Endothelial genetic ablation of Fgfbp1 results in transient hypervascularization but delays BBB maturation in specific CNS regions, as evidenced by both upregulation of Plvap and increased tracer leakage across the neurovasculature due to reduced Wnt/β-catenin activity. In addition, collagen IV deposition in the vascular basement membrane is reduced in mutant mice, leading to defective endothelial cell-pericyte interactions. Fgfbp1 is required cell-autonomously in mBECs to concentrate Wnt ligands near cell junctions and promote maturation of their barrier properties in vitro. Thus, Fgfbp1 is a crucial extracellular matrix protein during BBB maturation that regulates cell-cell interactions and Wnt/β-catenin activity. Summary: Fgfbp1 is necessary for collagen IV deposition in the CNS endothelium basement membrane and may facilitate presentation of Wnt ligands to their receptors on EC membranes by concentrating them close to cell junctions.
Soft Articulated Characters in Projective Dynamics

We propose a fast and robust solver to simulate continuum-based deformable models with constraints, in particular, rigid-body and joint constraints useful for soft articulated characters. Our method embeds the degrees of freedom of both articulated rigid bodies and deformable bodies in one unified constrained optimization problem, thus coupling the deformable and rigid bodies. Inspired by Projective Dynamics which is a fast numerical solver to simulate deformable objects, we also propose a novel local/global solver that takes full advantage of the pre-factorized system matrices to accelerate the solve of our constrained optimization problem. Therefore, our method can efficiently simulate character models, with rigid-body parts (bones) being correctly coupled with deformable parts (flesh). Our method is stable because backward Euler time integration is applied to both rigid and deformable degrees of freedom. Our unified optimization problem is rigorously derived from constrained Newtonian mechanics. When simulating only articulated rigid bodies as a special case, our method converges to the state-of-the-art rigid body simulators.
Biochemical aspects of single-node cuttings of Ricinodendron heudelotii (Baill.) in relation with rooting

Ricinodendron heudelotii (Njansang) is a valuable multipurpose tree species retained for domestication in Central and Western African regions. To measure the ability of rooting in relation with biochemical changes, basal single-node leafy cuttings were treated with different concentrations of indole-3-butyric acid (IBA), and 1-naphthaleneacetic acid (NAA) and cultured in fine sand media under poly-propagator system. The adventitious rooting was obtained in three distinct stages: Induction (0 to 20 days), initiation (20 to 30 days) and expression (30 to 40 days). Rooting response was higher within nodal cuttings pretreated with IBA than those pretreated with NAA. Polyphenoloxidase activity started to increase both in treated and control cutting during the initiation stage of the experiment and decreased after root emergence only in treated cuttings. Indole-3 acetic acid (IAA)-oxidase activity of auxin treated cuttings decreased as compared to the control. The peroxidase activity in IBA-treated cuttings increased slowly at the initiation stages and lightly at the expression stage. Total phenolic content was higher in IBA-treated cutting particularly at the initiation and expression stages. Phenolics and polyphenoloxidase might be playing key role for emergence of adventitious rooting and can be used as rooting enhancer in R. heudelotii.

A Comparative Evaluation of Bidirectional Step-Up DC-DC Converters

Abstract: This paper presents a comparative evaluation among the modified Cuk, modified buck-boost, and conventional boost bidirectional dc-dc power converters. It is shown that the efficiency of modified dc-dc Cuk power converter is the highest though the component count is the highest. It is also shown that the current ripples can be further reduced by integrating the two inductors of modified dc-dc Cuk power converter in one magnetic core. This paper shows that the modified dc-dc buck-boost power converter has almost no advantage compared to the conventional dc-dc boost power converter. Several experimental results are included to clarify the analysis.
The Creation of Mosaic Image using Colour Correction between the Images

Picture design applications depend upon both global and photometric enrolments between the pictures which are to make the mosaic. This system gives an anticipation shading amendment calculation to redressing the photometric differences. To start with, the picture to be shading remedied is sectioned into a few locales utilizing mean movement. At that point, associated areas are removed utilizing a district combination calculation. Neighborhood joint picture histograms of every locale are displayed as accumulations of truncated Gaussians utilizing a most extreme probability estimation system. At that point, neighborhood shading palette mapping capacities are processed utilizing these arrangements of Gaussians. The shading amendment is performed by applying those capacities to every one of the areas of the picture. A broad examination with ten other best in class shading revision calculations is exhibited, utilizing two distinctive picture pair information agreed. Outcome demonstrate that the given approach gets the better normal aggregate in one or more information agreed and assessment measurements and it is a likewise better strong for disappointments.
Morphological and genetic analysis of fish of a Carassius complex (Cyprinidae) in Lake Kasumigaura with reference to the taxonomic status of two all‐female triploid morphs

The classification of the Carassius complex (Cyprinidae) including all-female triploids, called ginbuna in Japanese, is so confused that three sympatric morphs of crucian carp in Lake Kasumigaura are categorized into two different subspecies within a species. We examined them in order to explain the coexistence of more than one subspecies and determine the founder of the triploid lineages in the crucian carp fauna in the lake. Principal component analysis proved that the three sympatric morphs had a morphometric basis distinguishable from each other. Ploidy was determined by flow cytometry which showed triploids in two morphs and diploids in the other morph. Stepwise discriminant analysis using only meristic characteristics could separate the diploids from the triploids. Phylogenetic analysis using mitochondrial DNA inferred two lineages in which one was composed of a triploid morph and the other was a diploid–triploid mixture. Disagreement between the taxonomic status and the phylogenetic status is explicable by assuming that the triploids in the Carassius complex had independent origins leading to the different subspecies. C. auratus langsdorfii appears to show genetic complexities that traditional taxonomic classification can not unravel. © 2003 The Linnean Society of London, Biological Journal of the Linnean Society, 2003, 79, 351–357.
Automatic synthesis of advertising images according to a specified style

Images are widely used by companies to advertise their products and promote awareness of their brands. The automatic synthesis of advertising images is challenging because the advertising message must be clearly conveyed while complying with the style required for the product, brand, or target audience. In this study, we proposed a data-driven method to capture individual design attributes and the relationships between elements in advertising images with the aim of automatically synthesizing the input of elements into an advertising image according to a specified style. To achieve this multi-format advertisement design, we created a dataset containing 13 280 advertising images with rich annotations that encompassed the outlines and colors of the elements, in addition to the classes and goals of the advertisements. Using our probabilistic models, users guided the style of synthesized advertisements via additional constraints (e.g., context-based keywords). We applied our method to a variety of design tasks, and the results were evaluated in several perceptual studies, which showed that our method improved users’ satisfaction by 7.1% compared to designs generated by nonprofessional students, and that more users preferred the coloring results of our designs to those generated by the color harmony model and Colormind.
Can the similarity index predict the causes of retractions in high-impact anesthesia journals? A bibliometric analysis

Background: The overall similarity index (OSI) and highest similarity scores (HSSs) from a single source might help to predict the potential reasons for the retraction from the anesthesia journals. Methods: Retracted publications, from five highest impact anesthesia journals, were retrieved from the MEDLINE and journal archives and analyzed using a plagiarism detection software (iThenticate) and manually verified for citation characteristics, OSI, HSS, and the presence, extent, and location of the duplicate text. The validity of the OSI including and excluding quotations and references and the HSS in predicting the potential reasons for retraction were tested using the receiver operating characteristic curves. Results: Of the total 138 retracted original and corresponding articles identified, 131 articles were analyzed. Most of them had the HSS more than 40% arising from a single source. Extensive degree of plagiarism (OSI score >35%) was identified through the main text of all analyzed retracted articles. The areas under the curves indicate that the OSI including and excluding quotations and bibliography and the HSS had reasonable ability to predict plagiarism and fabrication with a perfect sensitivity rate and low specificity but were weaker at distinguishing ethical misconduct or inconsistent or erroneous contents. Conclusions: The study highlights the presence of significant plagiarism in the retracted anesthesia publications irrespective to the reasons for retraction. The high OSI and the HSS could be useful tools to identify the potential manuscripts with high risks for plagiarism and fabrication.
Mechanisms of Ensemble Face Processing: Extraction of Summary, but not Single, Identity Shows Sensitivity to Non-Frontal Global Viewpoints

The recognition and perception of faces – both alone and in groups – is an important biological function, enabling humans to effectively engage with one another socially. This thesis describes viewpoint and identity interactions in processing face ensembles, helping vision scientists to understand the cognitive mechanisms taking place. I manipulated viewpoint or identity across two experiments. The first experiment had participants report an average or single viewpoint or identity, and the second experiment had participants report an average identity or a single identity across a wide range of viewpoints. I find that efficiency in average – but not single – identity extraction decreases as viewpoints are progressively non-frontal. Viewers also extract summary viewpoint better than a single viewpoint, and this ability also decreases as global viewpoints are non-frontal. The implications in the face ensemble processing system, general ensemble processing models, and future research are discussed below.
Corelation between somatic complaints, personality traits and positivity

Background/Aim. Many recent studies have focused on investigation the differences in personality traits and its role in promoting health and in moderating vulnerability to adversities and illness. The aim of our study was to investigate the role of somatic complaints in moderating the relation-ship between personality traits operationalized in Cybernetic Battery of Conative Tests (KON-6) model and positivity. Methods. The sample consisted of 512 students, 23.83 years old in average, 56.3% were female, 23% reported the presence of somatic complaints. In investigation, the Positivity Scale measuring positivity and the KON-6 measuring the activity of 6 dynamic personality traits ? activity regulation system (? ), organic function regulation system (? ), defense reactions regulation system (? ), attack regulation sys-tem (? ), homeostatic system coordination(? ) and regulation system integration (? ) were used. Results. All of the conative personality traits were significantly correlated with positivity, except for ? The subsample with somatic complaints reported higher scores in ? and ? traits, suggesting higher levels of anxiety and social reality impairment. The personality traits together with presence of somatic complaints significantly explained 26% of positivity variance, positively predicting positivity with higher activity of ? , and negatively with higher activity of ? and ? The moderating role of somatic complaints was found in two specific relations. Positivity can be predicted in a reverse manner by homeostatic system coordination (? ) but only in students with low somatic complaints, which was also the case for organic function regulation system (? ) but only in the presence of high somatic complaints. Conclusion. The positivity represents a good organizational and regulation disposition for regulating the cognitive, dynamic and motoric functions. It is also partially moderated by presence of somatic complaints. Practical benefit of these findings represents a concrete support for developing positivity in people, in order to empower people? s health.

Rule based Methodology for Recognition of Kannada Named Entities

-Named Entity Recognition (NER) is an important task in Natural Language Processing (NLP) applications like Information Extraction, Question Answering etc. In this paper we have proposed a rule based methodology to recognize Kannada named entities like person name, location name, organization name, number, measurement, time. We have manually developed suffix, prefix list and proper noun dictionary of 5000 words. Capitalization feature in English is useful for identifying named entities. But in Kannada capitalization feature is does not exists thus the NER task in Kannada becomes complex than in English. In Kannada proper nouns are indistinguishable from forms that are common nouns and adjectives. This ambiguity makes Kannada NER a challenging. The results of recognition are encouraging and the methodology has the precision around 86\%. Famous Kannada news paper Prajavani corpus is used to carry out experiments. The tool is language independent as there is no hard coding can be used for other Dravidian language group.
Investigation Analysis On Data Prefetching And Mapreduce Techniques For User Query Processing

: Big data is a group of data used for examining and extracting the useful information in recent days. Big data analytics is the application of advanced analytic methods against large data comprising structured, semi-structured and unstructured data. The main aim is to store, access and manipulate the data at one place. MapReduce (MR) is the principle of Big Data Processing model with distributed large datasets. Prefetching is a suitable technique for transferring the memory objects in memory hierarchy before required by processor. Many researchers carried out their research on the mapreduce method for responding to the user requested task through removing repeated tasks. But, the job completion time was not reduced using existing techniques as data prefetching was not carried out in existing methods. In order to address these problems, the existing prefetching and map reduce techniques are reviewed and drawbacks of techniques are listed in this paper.
HPV genotyping and p16/Ki-67 test significantly improve detection rate of high-grade cervical squamous intraepithelial lesion

Introduction Liquid-based cytology allows to apply modern and specific analyses of hrHPV genotyping in p16/Ki-67 test. All of these together could raise accuracy ratio for high-grade squamous intraepithelial lesion above 90%. The purpose of this study was to evaluate the diagnostic accuracy of LBC, hrHPV testing, and p16/Ki-67 testing in diagnosis of high-grade cervical intraepithelial lesions. Material and methods The study consisted of 176 women, out of which 50 presented with HSIL (CIN2) SCC (cervical intraepithelial lesion grade 2 squamous cell carcinoma). 126 women with a negative Pap test were pooled into the second group of the study. All patients were resampled for LBC, HPV genotyping, and for the p16/Ki-67 test. The research was carried out between May and December 2017, and second sampling were taken from 1 to 4 months. Results We reported a strong correlation between positive Pap test and hrHPV (p < 0.05) that met accuracy close to 90%. We noted correlations between a positive p16/Ki-67 with a positive Pap test: p < 0.001; 66% sensitivity (95% CI: 51.2–78.8%), 87.8% specificity (95% CI: 75.2–95.4%), 76.8% accuracy (95% CI: 67.2–84.7%), and OR 13.9 (95% CI: 4.9–39.2), especially HSIL and HPV16: p < 0.001; sensitivity (95% CI) 64.0, specificity (95% CI) 98.4, accuracy (95% CI) 88.6, OR (95% CI) 109.3. Conclusions The results of our study indicate hrHPV genotyping as a good biomarker for the triage of patients with an abnormal cytological report. In our opinion, the hrHPV test reaches the highest level of sensitivity, specificity, and accuracy, and should be considered as crucial diagnostic test in cervical screening.
Some Results on Observability of Polynomial Systems With First Integrals

The observability problem for a polynomial system possessing a polynomial first integral is examined. The property of distinguishability of level sets of a first integral is introduced. It is demonstrated that in the generic situation the polynomial system has this property everywhere in the state space excepting, may be, some subset of the equilibria set. Further, the property of strong distinguishability of level sets of a first integral is also introduced and one sufficient condition is given. It is discussed how to use the latter property together with the parametrized set of Luenberger-type observers for state estimation. Finally, we concern observability analysis on a level set and give some necessary and sufficient conditions.
