In this article, we present a parallelized primal-dual algorithm for solving constrained convex optimization problems. The is “block-based,” in which vectors of primal and dual variables are partitioned into blocks, each updated only by single processor. We consider four behaviors that could be asynchronous: 1) updates to variables; 2) 3) communications 4) variables. show any amount asynchrony ...

BACKGROUND We aimed (1) to describe the characteristics of patient-ventilator asynchrony in a population of critically ill children, (2) to describe the risk factors associated with patient-ventilator asynchrony, and (3) to evaluate the association between patient-ventilator asynchrony and ventilator-free days at day 28. METHODS In this single-center prospective study, consecutive children ad...

BACKGROUND Cardiac resynchronization Therapy (CRT) is an effective therapy for chronic heart failure with beneficial hemodynamic effects leading to a reduction of morbidity and mortality. The responder rates, however, are low. There are various and contentious echocardiographic parameters of myocardial asynchrony. Patient selection by echocardiographic assessment of asynchrony is thought to imp...

Abstract Although the positive effects of biodiversity on ecosystem functioning and stability have been extensively documented in literature, previous studies mostly explored mechanisms independently. It is unclear how may covary with those stability. Here we developed an integrated framework to explore links between underlying Specifically, were partitioned into complementarity ( CE ) selectio...

INTRODUCTION The mechanisms leading to patient/ventilator asynchrony has never been systematically assessed. We studied the possible association between asynchrony and respiratory mechanics in patients ready to be enrolled for a home non-invasive ventilatory program. Secondarily, we looked for possible differences in the amount of asynchronies between obstructive and restrictive patients and a ...

We introduce bounded asynchrony, a notion of concurrency tailored to the modeling of biological cell-cell interactions. Bounded asynchrony is the result of a scheduler that bounds the number of steps that one process gets ahead of other processes; this allows the components of a system to move independently while keeping them coupled. Bounded asynchrony accurately reproduces the experimental ob...

The phenomenon of anticipatory coarticulation provides a basis for the observed asynchrony between the acoustic and visual onsets of phones in certain linguistic contexts. This type of asynchrony is typically not explicitly modeled in audio-visual speech models. In this work, we study within-word audiovisual asynchrony using manual labels of words in which theory suggests that audio-visual asyn...

Speech recognition, by both humans and machines, benefits from visual observation of the face, especially at low signal-to-noise ratios (SNRs). It has often been noticed, however, that the audible and visible correlates of a phoneme may be asynchronous; perhaps for this reason, automatic speech recognition structures that allow asynchrony between the audible phoneme and the visible viseme outpe...

Patient–ventilator asynchrony can often be corrected by ventilator adjustment rather than sedation.
