Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles.  Methods: A total of 80 players, aged 18 to 30 years, played four types of video games;  Ru...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

Aims: The aim of this study was to compare the effect of teach-back method and video clip teaching on the sense of coherence of mothers with children suffering from asthma. Materials & Methods: In this field trial study 75 eligible mothers with children suffering from asthma were selected by convenience sampling method, but were randomly divided into three groups of: video clip group, teach-ba...

COVID-19 prompted the enforcement of strict social distancing measures in most parts world. These have serious implications for how people interact, socialise, and collaborate with one another. As contradicts nature human beings, connections are still maintained even at a distance. Various forms modern communication technologies (e.g., online networking sites, video conferencing tools) allow to...

This paper presents a systematic methodology based on the algebraic theory of signal processing to classify and derive fast algorithms for linear transforms. Instead of manipulating the entries of transform matrices, our approach derives the algorithms by stepwise decomposition of the associated signal models, or polynomial algebras. This decomposition is based on two generic methods or algebra...

Recognition of visual events as a video analysis task has become popular in machine learning community. While the traditional approaches for detection of video events have been used for a long time, the recently evolved deep learning based methods have revolutionized this area. They have enabled event recognition systems to achieve detection rates which were not reachable by traditional approac...

  Background: Autism spectrum disorder (ASD) is characterized by difficulty in the areas of social functioning, communication , and the presence of stereotypic and repetitive behaviors. Video modeling has been found to be an effective procedure for teaching a variety of skills to persons with autism. The purpose of the current study was to investigate the efficacy of video modeling procedure on...

In a natural experiment on a popular German Question & Answer community we investigate the applicability of the small-area hypothesis to the activation of user contributions through virtual rewards in the form of badges. Koo and Fishbach’s small-area hypothesis states that individuals in pursuit of a goal exhibit stronger motivation when they focus on whichever is smaller in size: the area of t...

Store-operated Ca(2+) entry mediated by STIM1 and ORAI1 constitutes one of the major Ca(2+) entry routes in mammalian cells. The molecular choreography of STIM1-ORAI1 coupling is initiated by endoplasmic reticulum (ER) Ca(2+) store depletion with subsequent oligomerization of the STIM1 ER-luminal domain, followed by its redistribution towards the plasma membrane to gate ORAI1 channels. The mech...

This paper describes the use of a prompted labeling solution to obtain class labels for user activity and context information on a mobile device. Based on the output from an activity recognition module, the prompt labeling module polls for class transitions from any of the activities (e.g. walking, running) to the standing still activity. Once a transition has been detected the system prompts t...
