The main challenge in the lead removal simulation is the behaviour of non-linearity relationships between the process parameters. The conventional modelling technique usually deals with this problem by a linear method. The substitute modelling technique is an artificial neural network (ANN) system, and it is selected to reflect the non-linearity in the interaction among the variables in the function. Herein, synthesized deep eutectic solvents were used as a functionalized agent with carbon nanotubes as adsorbents of Pb(2+)...

Low energy availability can place athletes at increased risk of injury and illness and can be detected by a low metabolic rate. The lowest metabolic rate is captured at the bedside, after an overnight fast and termed inpatient REE. Measurements done in a laboratory with a shorter overnight fast are termed outpatient REE. Although important to know what the lowest energy expenditure, a bedside measure and/or 12 h fast is not always practical or logistically possible particularly when you take into account an athlete's training schedule...

BACKGROUND: Traditional surgical training, largely based on the Halstedian model "see one, do one, teach one" is not as effective in the era of working time restrictions and elaborate shift-patterns. As a result, contemporary surgeons turned to educational methods outside the operating theatre such as simulation. Cadavers are high fidelity models but their use has ethical and cost implications and their availability may be limited. In this review, we explore the role of cadaveric simulation in modern surgical education...

BACKGROUND: Current robot surgery curricula developed by industry were designed for expert surgeons. We sought to identify the robotic curricula that currently exist in general surgery residencies and describe their components. METHODS: We identified 12 residency programs with robotic curricula. Using a structured coding form to identify themes including sequence, duration, emphasis and assessment, we generated a descriptive summary. RESULTS: Curricula followed a similar sequence: learners started with online modules and simulation exercises, followed by bedside experience during R2-R3 training years, and then operative opportunities on the console in the final years of training...

OBJECTIVES: In 2007, 31.7% of Georgia adolescents in grades 9-12 were overweight or obese. Understanding the impact of policies and interventions on obesity prevalence among young people can help determine statewide public health and policy strategies. This article describes a systems model, originally launched in 2008 and updated in 2014, that simulates the impact of policy interventions on the prevalence of childhood obesity in Georgia through 2034. METHODS: In 2008, using information from peer-reviewed reports and quantitative estimates by experts in childhood obesity, physical activity, nutrition, and health economics and policy, a group of legislators, legislative staff members, and experts trained in systems thinking and system dynamics modeling constructed a model simulating the impact of policy interventions on the prevalence of childhood obesity in Georgia through 2034...

PURPOSE: This work aims to generate cine CT images (i.e., 4D images with high temporal resolution) based on a novel principal component reconstruction (PCR) technique with motion learning from 2D fluoroscopic training images. METHODS: In the proposed PCR method, the matrix factorization is utilized as an explicit low-rank regularization of 4D images that are represented as a product of spatial principal components and temporal motion coefficients. The key hypothesis of PCR is that temporal coefficients from 4D images can be reasonably approximated by temporal coefficients learned from 2D fluoroscopic training projections...

INTRODUCTION: Disaster triage training for emergency medical service (EMS) providers is not standardized. Simulation training is costly and time-consuming. In contrast, educational video games enable low-cost and more time-efficient standardized training. We hypothesized that players of the video game "60 Seconds to Survival" (60S) would have greater improvements in disaster triage accuracy compared to control subjects who did not play 60S. METHODS: Participants recorded their demographics and highest EMS training level and were randomized to play 60S (intervention) or serve as controls...

Numerous attempts to move nursing handoff to the bedside failed within our organization. Upon retrospect, previous attempts lacked standardization, coordination, and clear expectations. With emphasis on implementing patient- and family-centered care to increase patient experience scores, we developed a standardized staff training methodology using didactic and simulation to address staff barriers to adoption, a standardized implementation process, and a process to hardwire the practice.

Phosphodiesterase type 5 inhibitors (PDE5i) (e.g., sildenafil, tadalafil, vardenafil, and avanafil) are drugs commonly used to treat erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia. PDE5i are not prohibited by the World Anti-Doping Agency (WADA) but are alleged to be frequently misused by healthy athletes to improve sporting performance. In vitro and in vivo studies have reported various effects of PDE5i on cardiovascular, muscular, metabolic, and neuroendocrine systems and the potential, therefore, to enhance performance of healthy athletes during training and competition...

In the radial smoothing (RS) scheme, small-scale self-focusing (SSSF) can degrade beam quality of a pump beam with a Gaussian pulse train, resulting in the degradation of the smoothing performance of the RS scheme. Considering SSSF of the pump beam in an optical Kerr medium (OKM), the propagation model of the laser beam in the RS scheme has been developed, and the effects of the characteristics of the pump beam and the thickness of the optical Kerr medium on the RS performance have further been numerically simulated and analyzed...

BACKGROUND: While adaptation to hypoxia at natural or simulated altitude has long been used with endurance athletes, it has only recently gained popularity for team-sport athletes. OBJECTIVE: To analyse the effect of hypoxic interventions on high-intensity intermittent running performance in team-sport athletes. METHODS: A systematic literature search of five journal databases was performed. Percent change in performance (distance covered) in the Yo-Yo intermittent recovery test (level 1 and level 2 were used without differentiation) in hypoxic (natural or simulated altitude) and control (sea level or normoxic placebo) groups was meta-analyzed with a mixed model...

BACKGROUND: High quality team leadership is important for the outcome of medical emergencies. However, the behavioral marker of leadership are not well defined. The present study investigated frequency of behavioral markers of shared mental models (SMM) on quality of medical management. METHOD: Training video recordings of 27 trauma teams simulating emergencies were analyzed according to team -leader's frequency of shared mental model behavioral markers. RESULTS: The results showed a positive correlation of quality of medical management with leaders sharing information without an explicit demand for the information ("push" of information) and with leaders communicating their situational awareness (SA) and demonstrating implicit supporting behavior...

The neocognitron is a deep (multi-layered) convolutional neural network that can be trained to recognize visual patterns robustly. In the intermediate layers of the neocognitron, local features are extracted from input patterns. In the deepest layer, based on the features extracted in the intermediate layers, input patterns are classified into classes. A method called IntVec (interpolating-vector) is used for this purpose. This paper proposes a new learning rule called margined Winner-Take-All (mWTA) for training the deepest layer...
