The efficiency of a parallel execution is always underlined. Many parallel programs, however, don’t run efficiently upon Networks of Workstations for a variety of reasons such as frequent accesses of remote memories. In this article we present a hardware-based monitoring system which uses a hardware monitor to keep watch of all of the underlying transactions on the network and allows tools to u...

In this study, we examined the relation of observed classroom practices to language and literacy achievement moderation for students from pre-K sixth grade. A total 136 studies (N = 107,882 participants) met inclusion criteria, which 108 were included meta-analysis other 28 narratively synthesized. The average zero-order (r .12) partial correlations p .04) statistically significant but weak in ...

[1] Recent studies attribute land double-frequency (DF) microseism observations to deep water generation. Here we show that near-coastal generation is generally the dominant source region. This determination is based on observations at land and ocean seismic stations, buoys, gravity-wave hindcasts, and on beamforming results from continental seismic arrays. Interactions between opposing ocean w...

A systematic review focused by plant on non-target impacts from agents deliberately introduced for the biological control of weeds found significant non-target impacts to be rare. The magnitude of direct impact of 43 biocontrol agents on 140 non-target plants was retrospectively categorized using a risk management framework for ecological impacts of invasive species (minimal, minor, moderate, m...

The internal deformation of the brain is far more complex than the rigid motion of the skull. An ultrasound imaging technique that we have developed has a combination of penetration, frame-rate, and motion detection accuracy required to directly observe, for the first time, the formation and evolution of shear shock waves in the brain. Experiments at low impacts on the traumatic brain injury sc...

AIMS AND BACKGROUND Studies reporting activated Wnt signaling in all stages of chronic myeloid leukemia (CML) have demonstrated that deregulation of the pathway plays a role in the pathogenesis of this disease. Several reports have suggested mechanisms for the deregulated Wnt signaling and beta-catenin stabilization observed in CML. One possible mechanism for beta-catenin stabilization could be...

INTRODUCTION Gallbladder cancer, which is characterized by rapid progression and a poor prognosis, is a complex disease to treat. Unfortunately, little is known currently about its etiology or pathogenesis. A better understanding of its carcinogenesis and determining risk factors that lead to its development could help improve the available treatment options. METHOD Based on this better under...
