Black Americans demonstrate comparatively low levels of depression and anxiety during the COVID-19 pandemic

Plos.org 

by Victoria Owens, Htay-Wah Saw

Introduction

During public health crises like the COVID-19 pandemic, populations can experience worsening mental health. Prior reports have suggested that Black Americans experienced lower rates of anxiety and depression than White Americans before the pandemic; however, during the pandemic, outcomes may be different as Black Americans have been disproportionately affected in terms of mortality, hospitalization, COVID-19 infection, and job loss. We documented... Читать дальше...

Spatial pattern and determinants of sufficient knowledge of mother to child transmission of HIV and its prevention among Nigerian women

Plos.org 

by Paul Omoh Olopha, Akin Olusoga Fasoranbaku, Ezra Gayawan

The lack of sufficient knowledge of mother to child transmission (MTCT) of human immunodeficiency virus (HIV) among pregnant women is considered a major contributor to new pediatric HIV infections globally, and increasing HIV related infant mortality especially in developing countries. Nigeria has the highest number of new HIV infections among children in the world. This study was designed to examine the spatial pattern and determinants... Читать дальше...



Acceleration of shooting and bouncing ray method based on OptiX and normal vectors correction

Plos.org 

by Gaogui Xu, Chunzhu Dong, Tao Zhao, Hongcheng Yin, Xuan Chen

The present paper deals with a new efficient shooting and bouncing ray (SBR) method based on OptiX and normal vectors correction. The basic idea is to make full use of the computing resources of the RTX series graphics cards. For ray tracing, the algorithm uses OptiX to invoke the built-in RT Cores of hardware. Thus, a fast intersection test can be implemented. To reduce the error of ray tracing caused by the facetted surface characterizing the curved surface... Читать дальше...

Predicting aptamer sequences that interact with target proteins using an aptamer-protein interaction classifier and a Monte Carlo tree search approach

Plos.org 

by Gwangho Lee, Gun Hyuk Jang, Ho Young Kang, Giltae Song

Oligonucleotide-based aptamers, which have a three-dimensional structure with a single-stranded fragment, feature various characteristics with respect to size, toxicity, and permeability. Accordingly, aptamers are advantageous in terms of diagnosis and treatment and are materials that can be produced through relatively simple experiments. Systematic evolution of ligands by exponential enrichment (SELEX) is one of the most widely used... Читать дальше...

Impact of Covid-19 on attendances for a 1st episode of reduced fetal movements: A retrospective observational study

Plos.org 

by Laia Marques-Fernandez, Swati Sharma, Una Mannu, Hsu Phern Chong

Background

Prior studies have demonstrated an increased stillbirth rate. It was suggested that the COVID-19 pandemic may have impacted on attendances for reduced fetal movements. Thus, we sought to ascertain the impact of the pandemic on attendances for reduced fetal movements (RFM) in our unit, ultrasound provision for reduced fetal movements, and the stillbirth rate.

Methods

This was a single site retrospective... Читать дальше...

Is personality linked to season of birth?

Plos.org 

by Hoseon Lee, Hye-Kyung Lee, Kounseok Lee

The environment is a very significant factor in early childhood development. Season of birth (SOB) is a proxy viable for the environment to which the babies are exposed, thus also significant in early development. This study investigates the association between SOB and personality. A total 2,962 college students were included as study participants. The participants were classified into four seasonal groups based on their birth month and underwent... Читать дальше...

Directed closure coefficient and its patterns

Plos.org 

by Mingshan Jia, Bogdan Gabrys, Katarzyna Musial

The triangle structure, being a fundamental and significant element, underlies many theories and techniques in studying complex networks. The formation of triangles is typically measured by the clustering coefficient, in which the focal node is the centre-node in an open triad. In contrast, the recently proposed closure coefficient measures triangle formation from an end-node perspective and has been proven to be a useful feature in network analysis. Читать дальше...

An introduction to DUIA: The database on urban inequality and amenities

Plos.org 

by Frederico Roman Ramos, Justus Uitermark

This article introduces DUIA, the Database on Urban Inequality and Amenities. DUIA includes data on the socio-economic development and amenities of 86 cities. The database especially covers cities outside the West, providing new opportunities for comparative research in fields suffering from a dearth of data. DUIA addresses three concerns that have not been resolved by other databases on cities. First, we draw upon remote sensing derived data from... Читать дальше...
