In most bird species, the timing of incubation onset may influence the degree of hatching asynchrony, which, together with variation in clutch size, affects reproductive success. In some domesticated species that usually show no hatching asynchrony, plasma prolactin concentrations in females rise with the onset of incubation and the end of laying, and this rise enhances incubation behavior and ...

Asynchronous myocardial contraction in heart failure is associated with poor prognosis. Resynchronization can be achieved by biventricular pacing (BVP), which leads to clinical improvement and reverse remodeling. However, there is a substantial subset of patients with wide QRS complexes in the electrocardiogram that does not improve despite BVP. QRS width does not predict benefit of BVP and onl...

BACKGROUND Established methods to determine asynchrony suffer from high intra- and interobserver variability and failed to improve patient selection for cardiac resynchronization therapy (CRT). Thus, there is a need for easy and robust approaches to reliably assess cardiac asynchrony. METHODS AND RESULTS We performed echocardiography in 100 healthy subjects and 33 patients with left bundle br...

A number of studies investigating the chronology of D N A synthesis in human chromosomes have indicated a degree of asynchrony among the members of the complement. The most striking asynchrony of D N A synthesis demonstrated within pairs of human chromosomes is the late replication of one of the X chromosomes shown by pulse labeling with tritiated thymidine in cultures of leucocytes (3, 4, 7, 8...

A calculus for distributed computation is studied, based upon four combinators. A ccntrai idea is an Abclian group of actions which models the interfaces between components of a distributed computing agent. Using a notion of bisimulation, congruence relations are defined over computing agents, and thence an algebraic theory is derived. The calculus models both synchronous and asvnchronous compu...

Declarative or constraint-based business process and workflow notations, in particular DECLARE and Dynamic Condition Response (DCR) graphs, have received increasing interest in the last decade as possible means of addressing the challenge of supporting at the same time flexibility in execution, adaptability and compliance. However, the definition of concurrent semantics, which is a necessary fo...

Mechanical ventilation (MV) is a life supporting treatment that, unfortunately, can be associated with several complications such as ventilator-induced lung injury, ventilator associated pneumonia or ventilation induced diaphragm dysfunction (VIDD)[1]. Clinicians generally try to provide assisted/supported ventilation instead of fully controlled ventilation in critically ill patients [2]. This ...
