Many analog-mixed-signal (AMS) circuits and control systems are naturally modeled as hybrid systems: state machines with a continuous dynamics given by ordinary differential equations (ODEs) at each state, and transitions whose guard conditions depend on the values of the continuous variables. The continuous dynamics for these models are often weakly non-linear. In particular, the intended beha...

PURPOSE: To determine whether there is a difference in hemodynamic responses to head-up tilt (HUT) subjects who do, and do not, experience acute mountain sickness (AMS) during exposure hypobaric hypoxia. We also aimed if those variables altered HUT correlated with AMS severity. METHODS: Fifteen participants completed three testing sessions: 1) VO2max test workload at 50% for hypoxia exposure; 2...

Two classes of linear involutory semigroups We construct two classes of involutory semigroups, which together with two already known generating rules yield n linear involutory semigroups of order n, where 2n = 2 n+2 ? 1 2 (n + 1)(n + 6) ; 2n+1 = 3 2 n+1 ? 1 2 (n 2 + 9n + 10) (1) for n 1. By the way, we extend the rule for the construction of linear archimedian involutory semigroups in L. Berg a...

Academic motivation is important to students' mental health and performance. One established measure the Motivation Scale (AMS), comprising 28 items. AMS assesses intrinsic motivation, extrinsic amotivation, which are further categorised into seven subscales. weakness of its length. In this study, we constructed validated a short version 14-item (SAMS). Data from two university student samples ...

The sperm cell is designed to transmit the male DNA to the oocyte. The integrity of this DNA is an obvious requisite for normal embryo development and a successful pregnancy. Nevertheless, DNA quality, mainly the presence of DNA fragmentation, is not habitually assessed as part of sperm analysis due to the technical complexity of such an assessment and misunderstanding about its significance. C...
