On the center of mass of asymptotically hyperbolic initial data sets [PDF]
, 2015 We define the (total) center of mass for suitably asymptotically hyperbolic time-slices of asymptotically anti-de Sitter spacetimes in general relativity.

Workflow Modelling and Analysis Based on the Construction of Task Models
The Scientific World Journal, 2015 We describe the structure of a workflow as a graph whose vertices represent tasks and the arcs are associated to workflow transitions in this paper. To each task an input/output logic operator is associated.

Particle scale force sensor based on intensity gradient method in granular photoelastic experiments
New Journal of Physics, 2019 The intensity gradient method ( G ^2 method), namely computing the light intensity gradient-squared, is a widely used non-invasive experimental method to extract stress information from quasi-two-dimensional photoelastic granular materials.

Monte Carlo Simulation of a Linear Accelerator and Electron Beam Parameters Used in Radiotherapy [PDF]
Iranian Journal of Medical Physics, 2009 Introduction: In recent decades, several Monte Carlo codes have been introduced for research and medical applications. These methods provide both accurate and detailed calculation of particle transport from linear accelerators. The main drawback of Monte

Optogenetic manipulation of cardiac repolarization gradients using sub-threshold illumination
Frontiers in Physiology, 2023 Introduction: Mechanisms underlying cardiac arrhythmias are typically driven by abnormalities in cardiac conduction and/or heterogeneities in repolarization time (RT) across the heart. While conduction slowing can be caused by either electrophysiological

A global isochronous center is linear
, 2021 Let $X$ be a polynomial vector field in $\mathbb{R}^2$ which, after one-point compactification of the plane, has a punctured neighbourhood $\dot U$ of the point at infinity which is foliated by closed orbits of $X$. If the period function of $X$ in $\dot U$ is bounded from below by a positive constant, $X$ is necessarily linear, hence conjugated, up to

On the Center of Some Finite Linear Groups [PDF]
Proceedings of the American Mathematical Society, 1975 This note proves two results, one in characteristic p p and the other in characteristic zero, which restrict the order of the center of some finite linear groups of degree less than a prime p p which divides the group order.

Scientific Reports, 2022 Avoiding over-pressurization in subsurface reservoirs is critical for applications like CO $$_2$$ 2 sequestration and wastewater injection. Managing the pressures by controlling injection/extraction are challenging because of complex heterogeneity in the

On the asymptotic stability of small nonlinear Dirac standing waves in a resonant case [PDF]
, 2007 We study the behavior of perturbations of small nonlinear Dirac standing waves. We assume that the linear Dirac operator of reference $H=D_m+V$ has only two double eigenvalues and that degeneracies are due to a symmetry of $H$ (theorem of Kramers).
