On the impulse approximation in atomic collision physics

Physica, 1970
Abstract Application of the quantum-mechanical impulse approximation in atomic collision physics leads to special problems caused by the long range of the Coulomb interaction between the individual particles. These problems are discussed using the exact T matrix as a starting point for the analysis.

Carried by impulse: The physics of water jetpacks

Physics Today, 2012
A jetpack can suspend a pilot in midair, in a way reminiscent of a magic carpet. But the magic is all in mechanical forces that can be readily estimated.

Physical properties and impulse strength of paper

Proceedings of the IEE Part A: Power Engineering, 1956
It is shown that the impulse strength of oil-impregnated paper, measured on single sheets, is related to the impulse strength of a lapped dielectric using the same paper. Attempts are made to relate the impulse strength to physical characteristics of the paper.

Impulsivity and Physical Aggression: Examining the Moderating Role of Anxiety

The American Journal of Psychology, 2014
Abstract Individuals vary in their propensity to engage in aggressive behaviors, and recent research has sought to identify individual differences that contribute to a person’s propensity for physical aggression. Previous research has shown that impulsivity and aggression have a consistent relational pattern among many different samples.

Physics of the impulsive phase of solar flares

Advances in Space Research, 1982
Abstract The physics of the impulsive phase of solar flares is discussed in relation to high resolution microwave, hard X-ray and ultraviolet observations. High spatial resolution observations of the structure of microwave flaring loops and their interpretation in terms of arcades of loops as the sites of primary energy release are presented ...

Physical pain and impulsivity in alcohol-dependent patients

Addiction Research & Theory, 2016
AbstractBackground: Physical pain and impulsivity are considered to be prevalent and significant factors that influence the course of alcohol dependence. The aim of the study was to investigate relationships between different dimensions of impulsivity and the current experience of physical pain in individuals entering alcohol treatment.Method: A sample

The Physical Nature of the Nerve Impulse*

Nature, 1933
ALL our sensations, all our movements, most of the activities of our nervous system, depend upon a certain transmitted disturbance which we call the nervous impulse: this, in the study of nerve activity, is what the atom, the electron and the quantum are to chemistry and physics.

How impulsivity shapes the interplay of impulsive and reflective processes involved in objective physical activity

Personality and Individual Differences, 2016
Abstract Grounded on the Reflective–Impulsive Model, a recent study by Cheval, Sarrazin, Isoard-Gautheur, Radel, and Friese (2015) found support for an interactive pattern between reflective (i.e., physical activity intentions) and impulsive (i.e., impulsive approach tendencies towards sedentary behaviors; IASB) processes to prospectively predict ...

An impulsive noise resistant physical layer for smart grid communications

2017 IEEE International Conference on Communications (ICC), 2017
Integrating wireless sensor networks (WSNs) in power substations for the future smart grid is growing in interest. Nevertheless, high voltage (HV) substations are harsh environments. In particular, impulsive noise needs to be taken into account. To tackle the constraints of these environments, we propose in this paper an efficient wideband channel ...
