The reordering window in PPS introduces latency, however, and this latency might be problematic for video surveillance applications, which stream live video. In live video streaming, the latency characteristics of the streaming mechanisms partially determine the freshness of the video content. The freshness of the video content, which is measured by the end-to-end latency from a frame being cap...

BACKGROUND Multiple studies have investigated the relationship between asbestos-related pleural plaques (PPs) and lung function, with disparate and inconsistent results. Most use chest radiographs to identify PPs and simple spirometry to measure lung function. High-resolution CT (HRCT) scanning improves the accuracy of PP identification. Complete pulmonary function tests (PFTs), including spiro...

OBJECTIVE To assess the reliability of contractile properties of the knee extensor muscles in 23 individuals with post-polio syndrome (PPS) and 18 age-matched healthy individuals. METHODS Contractile properties of the knee extensors were assessed from repeated electrically evoked contractions on 2 separate days, with the use of a fixed dynamometer. Reliability was determined for fatigue resis...

In this study, we hypothesized that many of the reported effects of phthalate esters and other peroxisome proliferators (PPs) in the testis are mediated by members of the PPactivated receptor (PPAR) family of transcription factors through alterations in proteins involved in steroidogenesis. Exposure of Leydig cells to PPs prevented cholesterol transport into the mitochondria after hormonal stim...

The intracellular signaling pathways associated with neuronal injury after perforant pathway stimulation of the rodent hippocampus have not been examined. To determine whether activation of the p42/p44 (Erk1/2) MAP kinase (MAPK) phosphorylation cascade is linked to neuronal injury after perforant pathway stimulation (PPS), we stained for phosphorylated Erk1/2 (P-Erk1/2) and for DNA fragmentatio...

A patellar bandage is often used by individuals with patellofemoral pain syndrome (PPS) to reduce pain and the additional sensorial input improves proprioception of the knee joint. The aim of this work was to assess the effect of a patellar bandage on the postural control of individuals with and without PPS. [Subjects and Methods] An analysis was performed of variables of center of pressure (Co...

The therapeutic efficacy of direct drug infusion into the brain, the target organ of transmissible spongiform encephalopathies, was assessed in transgenic mice intracerebrally infected with 263K scrapie agent. Pentosan polysulfate (PPS) gave the most dramatic prolongation of the incubation period, and amphotericin B had intermediate effects, but antimalarial drugs such as quinacrine gave no sig...

Polynomial phase signals (PPSs) have numerous applications in many fields including radar, sonar, geophysics, and radio communication systems. Therefore, estimation of PPS coefficients is very important. In this paper, a novel approach for PPS parameters estimation based on adaptive short-time Fourier transform (ASTFT), called the PPS-ASTFT estimator, is proposed. Using the PPS-ASTFT estimator,...

This paper describes a labelled corpus intended for training learning algorithms to attach prepositional phrases (PPs). Taken from the PTB2, we believe it is the largest available resource for this purpose, especially as it contains many patterns in which PPs occur ambiguously (nearly all previous research has focused on just one pattern) and we present some results for the five most common pat...

BACKGROUND Accurate prognostication of the trajectory of an illness provides multiple benefits in end-of-life care. Prognostic information facilitates more realistic decision making regarding ongoing treatment, fosters risk-benefit considerations of specific interventions, and contributes to appropriate utilization of health care services. OBJECTIVE The Palliative Performance Scale (PPS) has ...
