Abstract A combined numerical and experimental investigation is carried out to analyze the cycle-to-cycle variations (CCV) in an optically accessible spark-ignition engine with port fuel injection. stable unstable operating condition considered. Well-established turbulence, combustion, ignition models are employed large-eddy simulations (LES). High-speed measurements of velocity field via parti...

Clathrin-coated vesicles (CCV) mediate protein sorting and vesicular trafficking from the plasma membrane and the trans-Golgi network. Before delivery of the vesicle contents to the target organelles, the coat components, clathrin and adaptor protein complexes (APs), must be released. Previous work has established that hsc70/the uncoating ATPase mediates clathrin release in vitro without the re...

Cette étude examine comment procèdent les enfants en situation d’écriture inventée, lors d’une même passation, considérant tant le nombre de lettres produites pour chaque mot que unités orales auxquelles ces correspondent. À l’encontre l’hypothèse courante selon laquelle procèderaient à un moment donné façon unitaire (par exemple syllabique ou phonémique) et uniforme (quel soit l’objet écrire),...

BACKGROUND & OBJECTIVE ADHD is one of the most common mental disorders among children. We hypothesized that ADHD is associated with the impairment of the cardiac autonomic regulation. The aim of this study was to evaluate the cardiac autonomic regulation in children with ADHD at the rest and during orthostasis using short-term heart rate variability (HRV) analysis. METHODS Eighteen children w...

PURPOSE The diagnosis and monitoring of liver fibrosis is an important clinical issue; however, this is usually achieved by invasive methods such as biopsy. We aimed to determine whether histogram analysis of hepatobiliary phase images of gadoxetic acid-enhanced magnetic resonance imaging (MRI) can provide non-invasive quantitative measurement of liver fibrosis. METHODS This retrospective stu...

With the rapid growth of networked multimedia services in Internet, wireless network traffic has increased dramatically. However, current mainstream content caching schemes do not take into account cooperation different edge servers, resulting deteriorated system performance. In this paper, we propose a learning-based scheme to enable mutual among servers with limited resources, thus effectivel...

BACKGROUNDS Color Doppler ultrasonography (CDU) has not yet been established as a method to investigate the pathogenesis of thyrotoxicosis. OBJECTIVES Our first objective was to determine whether the measurement of peak systolic blood-flow velocity in the superior thyroid artery (STV) and thyroid tissue blood flow (TBF) using CDU could differentiate Graves' disease (GD) from painless thyroidi...
