Accelerating Smooth Games by Manipulating Spectral Shapes
, 2020 We use matrix iteration theory to characterize acceleration in smooth games. We define the spectral shape of a family of games as the set containing all eigenvalues of the Jacobians of standard gradient dynamics in the family. Shapes restricted to the real line represent well-understood classes of problems, like minimization.

Claustrum Volume Is Reduced in Multiple Sclerosis and Predicts Disability
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The claustrum is a small, thin structure of predominantly gray matter with broad connectivity and enigmatic function. Little is known regarding the impact of claustrum pathology in multiple sclerosis (MS). Methods This study assessed whether claustrum volume was reduced in MS and whether reductions were associated with specific ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Sleep spindles are an electrophysiological fingerprint of the sleeping human brain. They can be described in terms of duration, frequency, amplitude, and density, and vary widely according to age and sex. Spindles play a role in sleep and wake functions and are altered in several neurological and psychiatric disorders.

A comparative study of two models for the seismic analysis of buildings
Ingeniería e Investigación, 2012 This paper presents a model for the seismic analysis of buildings, taking two lumped masses at each level in a structure’s free nodes and comparing them to the traditional model which considers lumped masses per level, i.e., a mass for each floor of the ...

Some Experiences of Improving the Speed of Numerical Navier-Stokes Solver Using CUDA
Journal of Algorithms & Computational Technology, 2014 In this paper, the Graphics Processor Unit (GPU) is adopted to accelerate the codes of solving incompressible Navier-Stokes equations with two fully different numerical schemes: spectral method and finite difference method. Compared with the codes on CPU,

Double Power-law Formation by Sequential Particle Acceleration
The Astrophysical JournalSpectral double power laws are common in solar high-energy phenomena such as flares and interplanetary energetic-electron events. However, the physical mechanism that produces the changes in power-law index within a single spectrum is unclear.
