Limited access to improved drinking water, unimproved drinking water, and toilet facilities among households in Ethiopia: Spatial and mixed effect analysis

Plos.org 

by Daniel Gashaneh Belay, Zewdu Andualem

Background

Most people in sub-Saharan countries had limited drinking water services and toilet facilities. The collection of water can affect the health of the whole family, particularly children. Therefore this study aims to investigate determinants of limited access to drinking water services and spatial distributions of limited access to drinking water services, unimproved drinking water sources, and toilet facilities among households in Ethiopia.

Packaging contests between viral RNA molecules and kinetic selectivity

Plos.org 

by Inbal Mizrahi, Robijn Bruinsma, Joseph Rudnick

The paper presents a statistical-mechanics model for the kinetic selection of viral RNA molecules by packaging signals during the nucleation stage of the assembly of small RNA viruses. The effects of the RNA secondary structure and folding geometry of the packaging signals on the assembly activation energy barrier are encoded by a pair of characteristics: the wrapping number and the maximum ladder distance. Kinetic selection is found to be... Читать дальше...



Non-linear archetypal analysis of single-cell RNA-seq data by deep autoencoders

Plos.org 

by Yuge Wang, Hongyu Zhao

Advances in single-cell RNA sequencing (scRNA-seq) have led to successes in discovering novel cell types and understanding cellular heterogeneity among complex cell populations through cluster analysis. However, cluster analysis is not able to reveal continuous spectrum of states and underlying gene expression programs (GEPs) shared across cell types. We introduce scAAnet, an autoencoder for single-cell non-linear archetypal analysis, to identify GEPs and infer the relative activity of each GEP across cells. Читать дальше...

The stochastic logistic model with correlated carrying capacities reproduces beta-diversity metrics of microbial communities

Plos.org 

by Silvia Zaoli, Jacopo Grilli

The large taxonomic variability of microbial community composition is a consequence of the combination of environmental variability, mediated through ecological interactions, and stochasticity. Most of the analysis aiming to infer the biological factors determining this difference in community structure start by quantifying how much communities are similar in their composition, trough beta-diversity metrics. The central role that these metrics play in microbial... Читать дальше...

Sony shouldn't have killed the Vita

Engadget 

I loved the Vita. I have vivid memories of playing Persona 4 Golden for hours in the dark on my dad’s couch in Chicago flying around the world of Gravity Rush from an airplane seat and playing Murasaki Baby before bed. The Vita felt good and it made me happy. And then, Sony killed it.

Stephen Merchant and Elgin James Preview The Outlaws

Блог сайта «Face Tube is a fun name,» 

The Outlaws premieres Friday, April 1, on Prime Video.

TV Fanatic spoke with creators Stephen Merchant and Elgin James about the highly anticipated series.

Check out the interview below.

How did you both wind up working together on The Outlaws?

Stephen Merchant: Well, I had this very vague idea of people doing community service, based on the fact that my parents used to be involved with that world. When I was growing up, it seemed like an interesting environment for drama or comedy. Читать дальше...
