Intermittent androgen deprivation therapy is often used to treat prostate cancer, but there are few mathematical modelling studies of it. To explore the mechanisms such therapy, we describe intermittent with impulsive differential equations, then propose a novel model white noise. We first studied model’s basic properties including existence and uniqueness solution. By using theory stochastic i...

The complex coupling between charge carriers and phonons is responsible for diverse phenomena in condensed matter. We apply ultrafast electron diffuse scattering to unravel electron-phonon 1T-TiSe$_2$ both momentum time. are able distinguish effects due the real part of many-body bare electronic susceptibility, $\Re\left[\chi_0(\mathbf{q})\right]$, from those vertex, $g_{\mathbf{q}}$, by follow...

Impulsive synchronization of chaotic dynamic systems has some important applications to chaotic secure communication and chaotic spread-spectrum communication systems. In this paper we present some experimental results on impulsive synchronization between two Chua’s circuits. In our experiments, only one synchronizing impulse sequence is transmitted. The robustness of impulsive synchronization ...

OBJECTIVE The preference for sooner smaller over larger later rewards is a prominent manifestation of impulsivity in ADHD. According to the State Regulation Deficit (SRD) model, this impulsive choice is the result of impaired regulation of arousal level and can be alleviated by adding environmental stimulation to increase levels of arousal. METHOD To test this prediction, we studied the effec...

Impulsive noise interference of a biological origin is common in underwater acoustic environments. Here we report on properties of impulsive noise produced by sperm whales, recorded in deep water off the coast of Manus Island. We analyse the noise as a function of frequency band, and find strong non-Gaussian effects in the range 1-6 kHz. Sonar performance can be improved by utilising nonlinear ...

Occasionally, it happens to all of us: you speak out of turn during a meeting or you make a comment and immediate realize that you shouldn't have said it. Or you buy an expensive pair of shoes even though you actually cannot afford them. Two examples of daily‐live impulsive behavior, and more specifically of impulsive action (acting without forethought) and impulsive choice (preferring immediat...

It is well known that acute challenges with psychostimulants such as amphetamine affect impulsive behavior. We here studied the pharmacology underlying the effects of amphetamine in two rat models of impulsivity, the 5-choice serial reaction time task (5-CSRTT) and the delayed reward task (DRT), providing measures of inhibitory control, an aspect of impulsive action, and impulsive choice, respe...

We report a previously undescribed spectroscopic probe that makes use of electrons rescattered during the process of high-order harmonic generation. We excite coherent vibrations in SF(6) using impulsive stimulated Raman scattering with a short laser pulse. A second, more intense laser pulse generates high-order harmonics of the fundamental laser, at wavelengths of approximately 20-50 nm. The h...

Decimetric radio observations of the impulsive solar flare on October 5, 1992, 09:25 UT show a long series of quasi-periodic pulsations deeply modulating a continuum in the 0.6–2 GHz range that is slowly drifting toward lower frequencies. We propose a model in which the pulsations of the radio flux are caused by quasi-periodic particle acceleration episodes that result from a dynamic phase of m...
