Response of Bose gases in time-dependent optical superlattices [PDF]

open access: yes, 2006
The dynamic response of ultracold Bose gases in one-dimensional optical lattices and superlattices is investigated based on exact numerical time evolutions in the framework of the Bose-Hubbard model.

Time evolution in linear response: Boltzmann equations and beyond [PDF]

open access: yes, 2001
In this work a perturbative linear response analysis is performed for the time evolution of the quasi-conserved charge of a scalar field. One can find two regimes, one follows exponential damping, where the damping rate is shown to come from quantum ...

Fluctuations of two-time quantities and non-linear response functions [PDF]

open access: yes, 2010
We study the fluctuations of the autocorrelation and autoresponse functions and, in particular, their variances and co-variance. In a first general part of the Article, we show the equivalence of the variance of the response function with the second ...

Working Memory in Overweight Boys during Physical Education Classes

open access: yesChildren, 2023
This study examined the effect of small-sided football games (SSFG) and small-sided Ultimate Frisbee games (SSUFG) on working memory, response times, and feeling mood of boys with overweight. Twenty-eight boys (age 12.23 ± 1.58 years) participated in two

A short response-time atomic source for trapped ion experiments [PDF]

open access: yes, 2018
Ion traps are often loaded from atomic beams produced by resistively heated ovens. We demonstrate an atomic oven which has been designed for fast control of the atomic flux density and reproducible construction.

Dynamic Performance Analysis of a Compact Annular-Radial-Orifice Flow Magnetorheological Valve and Its Application in the Valve Controlled Cylinder System

open access: yesActuators, 2021
A compact annular-radial-orifice flow magnetorheological (MR) valve with variable radial damping gaps was proposed, and its structure and working principle were also described.

Modeling Cell-to-Cell Communication Networks Using Response-Time Distributions. [PDF]

open access: yes, 2018
Cell-to-cell communication networks have critical roles in coordinating diverse organismal processes, such as tissue development or immune cell response. However, compared with intracellular signal transduction networks, the function and engineering

Harnessing slow event-related fMRI to investigate trial-level brain-behavior relationships during object identification

open access: yesFrontiers in Human Neuroscience
Understanding brain-behavior relationships is the core goal of cognitive neuroscience. However, these relationships—especially those related to complex cognitive and psychopathological behaviors—have recently been shown to suffer from very small effect ...
