Impact of screen time during COVID-19 on eating habits, physical activity, sleep, and depression symptoms: A cross-sectional study in Indian adolescents

Plos.org 

by Panchali Moitra, Jagmeet Madan

Objective

This study attempted to address the limited knowledge regarding the impact of screen time (ST) on lifestyle behaviors in Indian adolescents during the ongoing COVID-19 pandemic. The objectives were to 1) evaluate frequency and duration of using screens, and screen addiction behaviors in 10–15 years old adolescents in Mumbai during the COVID-19 pandemic and 2) examine the association of ST with lifestyle behaviors- eating habits, snacking patterns...

Applying machine learning to explore the association between biological stress and near misses in emergency medicine residents

Plos.org 

by Sonnet Xu, Judith E. Arnetz, Bengt B. Arnetz

Physician stress is associated with near misses and adverse medical events. However, little is known about physiological mechanisms linking stress to such events. We explored the utility of machine learning to determine whether the catabolic stress hormone cortisol and the anabolic, anti-stress hormone dehydroepiandrosterone sulfate (DHEA-S), as well as the cortisol to DHEA-S ratio relate to near misses in emergency medicine residents during active duty in a trauma 1 emergency department.

Relationships between maximum tongue pressure and second formant transition in speakers with different types of dysarthria

Plos.org 

by Toshiaki Tamura, Yasuhiro Tanaka, Yoshihiro Watanabe, Katsuro Sato

The effects of muscle weakness on speech are currently not fully known. We investigated the relationships between maximum tongue pressure and second formant transition in adults with different types of dysarthria. It focused on the slope in the second formant transition because it reflects the tongue velocity during articulation. Sixty-three Japanese speakers with dysarthria (median age, 68 years; interquartile range, 58–77... Читать дальше...



Diversity of plant parasitic nematodes characterized from fields of the French national monitoring programme for the Columbia root-knot nematode

Plos.org 

by Nathan Garcia, Eric Grenier, Alain Buisson, Laurent Folcher

Plant parasitic nematodes are highly abundant in all agrosystems and some species can have a major impact on crop yields. To avoid the use of chemical agents and to find alternative methods to manage these pests, research studies have mainly focused on plant resistance genes and biocontrol methods involving host plants or natural enemies. A specific alternative method may consist in supporting non-damaging indigenous species that... Читать дальше...

Laboratory evaluation of the effect of compaction method and compaction work on the performance of SMA-13 mixture

Plos.org 

by Jinshun Xue, Yingjun Jiang, Yuanbiao Zheng, Shaohui Xiong

The influence of compaction methods such as the Marshall compaction method (MCM), vibration compaction method (VCM) and gyration compaction method (GCM), on the performance of stone mastic asphalt (SMA-13) mixture has yet to be explored. Therefore, to compare the influences of compaction methods and work on the physical and mechanical properties of SMA-13 mixture, the volume parameters, mechanical properties, and gradation changes...

Task-induced neural covariability as a signature of approximate Bayesian learning and inference

Plos.org 

by Richard D. Lange, Ralf M. Haefner

Perception is often characterized computationally as an inference process in which uncertain or ambiguous sensory inputs are combined with prior expectations. Although behavioral studies have shown that observers can change their prior expectations in the context of a task, robust neural signatures of task-specific priors have been elusive. Here, we analytically derive such signatures under the general assumption that the responses of sensory neurons encode... Читать дальше...

Simple model for encoding natural images by retinal ganglion cells with nonlinear spatial integration

Plos.org 

by Jian K. Liu, Dimokratis Karamanlis, Tim Gollisch

A central goal in sensory neuroscience is to understand the neuronal signal processing involved in the encoding of natural stimuli. A critical step towards this goal is the development of successful computational encoding models. For ganglion cells in the vertebrate retina, the development of satisfactory models for responses to natural visual scenes is an ongoing challenge. Standard models typically apply linear integration of visual stimuli over space... Читать дальше...

A bio-mimetic miniature drone for real-time audio based short-range tracking

Plos.org 

by Roei Zigelman, Ofri Eitan, Omer Mazar, Anthony Weiss, Yossi Yovel

One of the most difficult sensorimotor behaviors exhibited by flying animals is the ability to track another flying animal based on its sound emissions. From insects to mammals, animals display this ability in order to localize and track conspecifics, mate or prey. The pursuing individual must overcome multiple non-trivial challenges including the detection of the sounds emitted by the target, matching the input received by its (mostly) two sensors...

Comprehensive mouse microbiota genome catalog reveals major difference to its human counterpart

Plos.org 

by Silas Kieser, Evgeny M. Zdobnov, Mirko Trajkovski

Mouse is the most used model for studying the impact of microbiota on its host, but the repertoire of species from the mouse gut microbiome remains largely unknown. Accordingly, the similarity between human and mouse microbiomes at a low taxonomic level is not clear. We construct a comprehensive mouse microbiota genome (CMMG) catalog by assembling all currently available mouse gut metagenomes and combining them with published reference and metagenome-assembled genomes.
