Pierre-Marc Jodoin, Lucia Maddalena, Alfredo Petrosino, Yi Wang
Scene background initialization is the process by which a method tries to recover the background image of a video without foreground objects in it. Having a clear understanding about which approach is more robust and/or more suited to a given scenario is of great interest to many end users or practitioners. The aim of this paper is to provide an extensive survey of scene background initialization methods as well as a novel benchmarking framework. The proposed framework involves several evaluation metrics and state-of-the-art methods, as well as the largest video dataset ever made for this purpose...

BACKGROUND: A general practitioner (GP)-targeted intervention aimed at improving the prescribing of appropriate polypharmacy for older people was previously developed using a systematic, theory-based approach based on the UK Medical Research Council's complex intervention framework. The primary intervention component comprised a video demonstration of a GP prescribing appropriate polypharmacy during a consultation with an older patient. The video was delivered to GPs online and included feedback emphasising the positive outcomes of performing the behaviour...

BACKGROUND: Synovitis of the shoulder is a common entity that is poorly described. This study aims to create a simple and reliable classification system for glenohumeral synovitis, which would benefit further research related to synovitis and outcomes. METHODS: Twenty 30-second shoulder arthroscopy videos were distributed to 19 fellowship-trained orthopedic surgeons. The observers responded with their years in practice, fellowship type, whether synovitis affects outcomes, and whether synovitis affects plans...

Purpose: To design an instrument to check the perception of minimal contrasts by through pairs of signs, which differ in one the following parameters: handshape, hand location, hand movement and hand orientation. Methods: An inventory of minimal pairs was made and some pictures were drawn by a visual artist. These pictures were organized into three columns, which could be equal or different from each other in the pair. A video file with an interpreter making two signs at a time was played to the individual taking the test and this was expected to watch the signs and point to the pictures that corresponded to them...

The nematode, Caenorhabditis elegans' compact nervous system of only 302 neurons underlies a diverse repertoire of behaviors. To facilitate the dissection of the neural circuits underlying these behaviors, the development of robust and reproducible behavioral assays is necessary. Previous C. elegans behavioral studies have used variations of a "drop test", a "chemotaxis assay", and a "retention assay" to investigate the response of C. elegans to soluble compounds. The method described in this article seeks to combine the complementary strengths of the three aforementioned assays...

Nuclear receptors (NR) are emerging as key players in the central nervous system (CNS) with reported implications in physiological and pathophysiological conditions. While other NR have been studied, it is unknown whether invalidation of the pregnane xenobiotic receptor (PXR, NR1I2) corresponds to neurological modifications in the adult brain. PXR(-/-) C57BL/6j and wild type mice were used to investigate: i) recognition memory, motor coordination, and anxiety-like behaviors; ii) longitudinal video-electroencephalographic (EEG) recordings and frequency wave analysis; iii) neurovascular structures by histological evaluation and expression of the cerebrovascular tight junctions ZO1 and CLDN5...

BACKGROUND: Perioperative, maternity, and newborn nurses discovered a solution using modern technology to facilitate earlier "connection" between postcesarean section mothers and their newborns using televised video conference (VC) or telemedicine. Videoconferencing used as a support in cases of separation after childbirth can facilitate a first "meeting" closer to the time of birth. AIM: The aim of this study was to design and validate the use of video conferencing to facilitate "bonding" between postdelivery cesarean delivery mothers who are separated from their infants...

We evaluated five competing hypotheses about what predicts romantic interest. Through a half-block quasi-experimental design, a large sample of young adults (i.e., responders; n = 335) viewed videos of opposite-sex persons (i.e., targets) talking about themselves and responders rated the targets' traits and their romantic interest in the target. We tested whether similarity, dissimilarity, or overall trait levels on mate value, physical attractiveness, life history strategy, and the Big-Five personality factors predicted romantic interest at zero acquaintance, and whether sex acted as a moderator...

INTRODUCTION: Bladder and bowel dysfunction (BBD) can negatively impact the quality of life (QoL) of children. Urotherapy is an accepted treatment option for BBD; however, literature that examines the impact of management options on QoL in this population is scarce. OBJECTIVE: To determine whether a bladder training video (BTV) is non-inferior to standard urotherapy (SU) in improving QoL in children with BBD. METHODS: Children aged 5-10 years and who scored ≥11 on the Vancouver Non-Neurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire (NLUTD/DES) were recruited from a pediatric tertiary care center...

INTRODUCTION: Video games are mainly considered to be of entertainment value in our society. Laparoscopic surgery and video games are activities similarly requiring eye-hand and visual-spatial skills. Previous studies have not conclusively shown a positive correlation between video game experience and improved ability to accomplish visual-spatial tasks in laparoscopic surgery. This study was an attempt to investigate this relationship. AIM: The aim of the study was to investigate whether previous video gaming experience affects the baseline performance on a laparoscopic simulator trainer...

REVIEW
M Nasiri Sarvi, Y Luo
Osteoporotic hip fracture, mostly induced in falls among the elderly, is a major health burden over the world. The impact force applied to the hip is an important factor in determining the risk of hip fracture. However, biomechanical researches have yielded conflicting conclusions about whether the fall-induced impact force can be accurately predicted by the available models. It also has been debated whether or not the effect of impact force has been considered appropriately in hip fracture risk assessment tools...
