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.

Cortical spreading depression in migraine-time to reconsider?
Arquivos de Neuro-Psiquiatria, 2015 New evidence concerning the pathophysiology of migraine has come from the results of therapeutic transcranial magnetic stimulation (tTMS). The instantaneous responses to single pulses applied during the aura or headache phase, together with a number of ...

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,

Design and Modeling of an Impulse Continuously Variable Transmission with a Rotational Swashplate
International Journal of Automotive Science and Technology, 2020 A novel mechanical impulse continuously variable transmission (ICVT) is developed to provide continuously variable speed ratios and smooth acceleration for drivetrains based on a rotational swashplate, and its design principle is illustrated.

Parameter identification using moment of velocity [PDF]
Royal Society Open Science, 2019 Many physical systems can be adequately modelled using a second-order approximation. Thus, the problem of system identification often reduces to the problem of estimating the position of a single pair of complex–conjugate poles.

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.

On a delayed epidemic model with non-instantaneous impulses
Communications on Pure and Applied Analysis, 2020 In the traditional SIR model a new group into the population is added. It is the group of individuals that carries the disease but does not show symptoms. It is studied the case that the infectious diseases are controlled by a pulse vaccination strategy but in a non-instantaneous way.

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.

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 ...
