The impact of exercise interventions concerning executive functions of children and adolescents with attention-deficit/hyperactive disorder: a systematic review and meta-analysis

open access: yesInternational Journal of Behavioral Nutrition and Physical Activity, 2021
Background Previous studies found that exercise interventions have positive effects on executive functions of the general population. However, studies seldom target executive functions of children and adolescents with attention-deficit hyperactivity ...

A PDE Approach to Data-driven Sub-Riemannian Geodesics in SE(2) [PDF]

open access: yes, 2015
We present a new flexible wavefront propagation algorithm for the boundary value problem for sub-Riemannian (SR) geodesics in the roto-translation group $SE(2) = \mathbb{R}^2 \rtimes S^1$ with a metric tensor depending on a smooth external cost $\mathcal{

Validation of the Indonesian resilience evaluation scale in an undergraduate student population

open access: yesBMC Public Health, 2022
Background Psychological resilience is an important factor in coping with Potentially Traumatic Events (PTEs) and might mitigate the development of trauma-related disorders. Due to the high risk of natural disasters, criminal activity, and transportation

Space-time domain solutions of the wave equation by a non-singular boundary integral method and Fourier transform

open access: yes, 2017
The general space-time evolution of the scattering of an incident acoustic plane wave pulse by an arbitrary configuration of targets is treated by employing a recently developed non-singular boundary integral method to solve the Helmholtz equation in the

A scoping review of the Clinical Frailty Scale

open access: yesBMC Geriatrics, 2020
Background Frailty is increasingly recognized as an important construct which has health implications for older adults. The Clinical Frailty Scale (CFS) is a judgement-based frailty tool that evaluates specific domains including comorbidity, function ...

A Stable Higher Order Space-Time Galerkin Scheme for Time Domain Integral Equations

open access: yes, 2014
Stability of time domain integral equation (TDIE) solvers has remained an elusive goal for many years. Advancement of this research has largely progressed on four fronts: (1) Exact integration, (2) Lubich quadrature, (3) smooth temporal basis functions ...

Assembly and Analysis of Cell-Scale Membrane Envelopes

open access: yesJournal of Chemical Information and Modeling, 2021
The march toward exascale computing will enable routine molecular simulation of larger and more complex systems, for example, simulation of entire viral particles, on the scale of approximately billions of atoms─a simulation size commensurate with a ...

Spacelike surface families interpolating common asymptotic curves in Minkowski 3-space

open access: yesFrontiers in Physics
In this paper, we propose a method for constructing families of spacelike surfaces in Minkowski 3-spaceE13 that share Bertrand curves as asymptotic curves.

Cross-cultural adaptation of the Perceived Risk of HIV Scale in Brazilian Portuguese

open access: yesHealth and Quality of Life Outcomes, 2021
Background Valid and reliable instruments are needed to measure the multiple dimensions of perceived risk. The Perceived Risk of HIV Scale is an 8-item measure that assesses how people think and feel about their risk of infection. We set out to perform a

A fast GPU Monte Carlo Radiative Heat Transfer Implementation for Coupling with Direct Numerical Simulation

open access: yes, 2018
We implemented a fast Reciprocal Monte Carlo algorithm, to accurately solve radiative heat transfer in turbulent flows of non-grey participating media that can be coupled to fully resolved turbulent flows, namely to Direct Numerical Simulation (DNS). The
