Instants and Instantaneous Velocity [PDF]
, 2008 This paper will argue that the puzzles about instantaneous velocity, and rates of change more generally, are the result of a failure to recognize an ambiguity in the concept of an instant, and therefore of an instantaneous state.

ExistenceofMildSolutionsforaClassofSecond-order StochasticEvolutionEquationswithImpulses
Journal of Harbin University of Science and Technology, 2023 The existence of mild solutions for a class of second-order non-autonomous stochastic evolution equations with instantaneous impulses is studied in Hilbert space. By using Sadovskii ′ s fixed point theorem and the theory

Advanced Functional Materials, EarlyView.A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Stability properties of neural networks with non-instantaneous impulses
Mathematical Biosciences and Engineering, 2019 In this paper, we consider neural networks in the case when the neurons are subject to a certain impulsive state displacement at fixed moments and the duration of this displacement is not negligible small (these are known as non-instantaneous impulses). We examine some stability properties of the equilibrium of the model.

Advanced Healthcare Materials, EarlyView.Conventional therapies suffer from poor blood–brain barrier (BBB) penetration and disordered ion/reactive oxygen species (ROS) homeostasis, hindering precise neurological treatment. Electrochemical strategies achieve accurate spatiotemporal regulation of neural homeostasis.

Practical stability of differential equations with non-instantaneous impulses
, 2017 The concept of practical stability is generalized to nonlinear differential equations with non-instantaneous impulses. These type of impulses start their action abruptly at some points and then continue on given finite intervals.

Mild solution of fractional order differential equations with not instantaneous impulses
Open Mathematics, 2015 In this paper, we investigate the boundary value problems of fractional order differential equations with not instantaneous impulse. By some fixed-point theorems, the existence results of mild solution are established.

Instantaneous and Cumulative Influences of Competition on Impulsive Choices in Domestic Chicks [PDF]
Frontiers in Neuroscience, 2011 This study examined instantaneous and cumulative effects of competitive interactions on impulsiveness in the inter-temporal choices in domestic chicks. Chicks were trained to peck colored beads to gain delayed food rewards (1 or 6 grains of millet delivered after a delay ranging between 0 and 4.5 s), and were tested in binary choices between a small ...
