Virtual reality as a tool for balance research: Eyes open body sway is reproduced in photo-realistic, but not in abstract virtual scenes

Plos.org 

by Lorenz Assländer, Stephan Streuber

Virtual reality (VR) technology is commonly used in balance research due to its ability to simulate real world experiences under controlled experimental conditions. However, several studies reported considerable differences in balance behavior in real world environments as compared to virtual environments presented in a head mounted display. Most of these studies were conducted more than a decade ago, at a time when VR was still struggling with major technical limitations (delays... Читать дальше...

Application of controlled release urea improved grain yield and nitrogen use efficiency: A meta-analysis

Plos.org 

by Shuhao Zhu, Liyuan Liu, Yan Xu, Yanying Yang, Rongguang Shi

The application of controlled release urea (CRU) has been proposed as a crucial method to reduce the adverse environmental effects induced by conventional urea (CU). Yet, a systematic and quantitative analysis on how CRU affects staple crop production including wheat (Triticum aestivum L.), maize (Zea mays L.), and rice (Oryza sativa L.) is lacking. Here, a meta-analysis was conducted to determine how CRU influences soil chemical properties... Читать дальше...

Controlling your contents with the breath: Interactive breath interface for VR, games, and animations

Plos.org 

by Jong-Hyun Kim, Jung Lee

In this paper, we propose a new interface to control VR(Virtual reality) contents, games, and animations in real-time using the user’s breath and the acceleration sensor of a mobile device. Although interaction techniques are very important in VR and physically-based animations, UI(User interface) methods using different types of devices or controllers have not been covered. Most of the proposed interaction techniques have focused on screen touch and motion recognition. Читать дальше...



The phosphoinositide regulatory network in Trypanosoma brucei: Implications for cell-wide regulation in eukaryotes

Plos.org 

by Igor Cestari, Kenneth Stuart

The unicellular eukaryote Trypanosoma brucei undergoes extensive cellular and developmental changes during its life cycle. These include regulation of mammalian stage surface antigen variation and surface composition changes between life stages; switching between glycolysis and oxidative phosphorylation; differential mRNA editing; and changes in posttranscriptional gene expression, protein trafficking, organellar function, and cell morphology. These diverse... Читать дальше...

“We have already heard that the treatment doesn't do anything, so why should we take it?”: A mixed method perspective on Chagas disease knowledge, attitudes, prevention, and treatment behaviour in the Bolivian Chaco

Evolution of linkage and genome expansion in protocells: The origin of chromosomes

Plos.org 

by András Szilágyi, Viktor Péter Kovács, Eörs Szathmáry, Mauro Santos

Chromosomes are likely to have assembled from unlinked genes in early evolution. Genetic linkage reduces the assortment load and intragenomic conflict in reproducing protocell models to the extent that chromosomes can go to fixation even if chromosomes suffer from a replicative disadvantage, relative to unlinked genes, proportional to their length. Here we numerically show that chromosomes spread within protocells even... Читать дальше...
