Summary– We generalize the sum of remainders map by replacing set summation indices with an arbitrary finite nonempty positive integers. The iteration this produces interesting dynamical behavior, which we explore. In particular, discuss existence nonzero fixed points and some their properties.
We investigated whether women show larger heart rate variability (HRV) than men after controlling for a large number of health-related covariates, using two indices of HRV, namely respiratory sinus arrhythmia (RSA) and approximate entropy (ApEn). In a twin design, the heritability of both indices was examined. The covariation between RSA and ApEn, a measure of heart rate dynamics derived from n...
in this article, we demonstrate an analytic-numeric solution for some dynamical systems using the multistagehomotopy perturbation method. the method yields results that are in complete agreement with their numericalcounterparts.
this paper provides a review on major ergodic features of semi-independent hyper mv {algebra dynamical systems. theorems are presentedto make contribution to calculate the entropy. particularly, it is proved that thetotal entropy of those semi-independent hyper mv {algebra dynamical systemsthat have a generator can be calculated with respect to their generator ratherthan considering all the par...
105 inTroducTion Civilian Tactical Emergency Medical Support (TEMS) has a long history in the United States. Enormous progress has been made during the past ten years in developing professional and operational standards within the field. However, to date, there still exists no standard of care within TEMS specifically, and more broadly for high threat pre-hospital trauma care. Current civilian ...

Cerebral language lateralization can be assessed in several ways. In healthy subjects, functional MRI (fMRI) during performance of a language task has evolved to be the most frequently applied method. Functional transcranial Doppler (fTCD) may provide a valid alternative, but has been used rarely. Both techniques have their own strengths and weaknesses and as a result may be applied in differen...
In problems where the temporal evolution of a nonlinear system cannot be followed, a method for studying the fluctuations of spatial patterns has been developed. That method is applied to well-known problems in deterministic chaos (the logistic map and the Lorenz model) to check its effectiveness in characterizing the dynamical behaviors. It is found that the indices μq are as useful as the Lya...
An algorithm is presented for analyzing the transitive behavior of reversible one-dimensional cellular automata, where reversibility refers to injective cellular automata which have a bijective behavior for spatially periodic configurations. In particular we study reversible automata where the ancestors of finite sequences differ at both ends (technically, with both Welch indices different from...
