To investigate the effect of light cue on the resetting of the peripheral clocks, we examined the resetting processes of clock genes (Per1, Per2, Bmal1, Cry1, Dec1, and Rev-erbalpha) in the liver and heart of rats after the feeding and light-dark (LD) reversal via a 24-h light period transition. The liver clock was reset quickly within 3 days, while the heart clock needed a longer time course o...

Abstract Funding Acknowledgements Type of funding sources: None. Backgrounds Catheter ablation for paroxysmal supraventricular tachycardia (PSVT) is curative treatment. However, diagnosis atrial (AT) distinguishing from other PSVTs are often challenging, especially when the terminates after pacing or does not sustain long enough diagnostic maneuvers. We sought a new method AT. Methods One-hundr...

Nonergodic attractors can robustly appear in symmetric systems as structurally stable cycles between saddle-type invariant sets. These saddles may be chaotic giving rise to "cycling chaos." The robustness of such attractors appears by virtue of the fact that the connections are robust within some invariant subspace. We consider two previously studied examples and examine these in detail for a n...

BACKGROUND Resetting and entrainment have both been used to characterize the electrophysiological properties of the reentrant circuit in ventricular tachycardia. Several entrainment studies have suggested that the circuit has decremental properties, because the return cycle increases at faster pacing rates. Resetting, however, demonstrates a fully excitable gap in the majority of tachycardias. ...

To test the hypothesis that acute resetting of baroreflex control of heart rate (HR) is enhanced during pregnancy, we determined whether the rightward shift in the baroreflex relationship between arterial pressure and HR after arterial pressure is raised [~25 mmHg for 30 min, due to infusion of phenylephrine (PE) or methoxamine (Meth)] is greater in late pregnant compared with nonpregnant consc...

We derived analytically and checked numerically a set of novel conditions for the existence and the stability of phase-locked modes in a biologically relevant master-slave neural network with a dynamic feedback loop. Since neural oscillators even in the three-neuron network investigated here receive multiple inputs per cycle, we generalized the concept of phase resetting to accommodate multiple...

In current scenario highresolutionADC architecture based on a resetting modulator required high gain operational Transcoductace Amplifier (OTA)and quanitizerin low-voltage nanometer-scale CMOSprocesses because of good speed and calibration-free response are becoming more popular in communication system. Proposed work achieves such high resolution, despite poor component matching using Folded ca...

We study the effects of stochastic resetting on geometric Brownian motion (GBM), a canonical multiplicative process for non-stationary and non-ergodic dynamics. Resetting is sudden interruption process, which consecutively renews its show that, although renders GBM stationary, resulting remains non-ergodic. Quite surprisingly, effect pivotal in manifesting behavior. In particular, we observe th...

We study simple diffusion where a particle stochastically resets to its initial position at a constant rate r. A finite resetting rate leads to a nonequilibrium stationary state with non-Gaussian fluctuations for the particle position. We also show that the mean time to find a stationary target by a diffusive searcher is finite and has a minimum value at an optimal resetting rate r*. Resetting ...

Abstract In the present work we revisit problem of behavior a subdiffusive continuous time random walk (CTRW) under resetting. The resetting process is considered as renewal with power-law distribution waiting times between events. We consider both case complete resetting, when an ordinary CTRW starts anew after event, and incomplete internal memory nor erased by restarts aged one. Using specia...
