As an environmentally friendly alternative for the production of high-performance modified asphalt by chemical reactions, a liquid-state polyurethane-precursor-based reactive modifier (PRM) was developed and employed in modification. In contrast to traditional solid bitumen modifier, example, rubber thermoplastic elastomers, PRM as liquid has more significant advantages reducing energy consumpt...

Cross-reactive dengue virus (DENV) antibodies directed against the envelope (E) and precursor membrane (prM) proteins are believed to contribute to the development of severe dengue disease by facilitating antibody-dependent enhancement of infection. We and others recently demonstrated that anti-prM antibodies render essentially non-infectious immature DENV infectious in Fcγ-receptor-expressing ...

A tool remaining useful life prediction method based on a non-homogeneous Poisson process and Weibull proportional hazard model (WPHM) is proposed, taking into account the grinding repair of machine tools during operation. The intrinsic failure rate built according to data. WPHM established by collecting vibration information operation introducing covariates describe In combination with repair,...

PURPOSE The Epley particle repositioning maneuver (PRM) is an effective treatment for benign paroxysmal positional vertigo (BPPV), the most common cause of peripheral vertigo in primary care settings. The goal of this study was to determine whether the use of an iPhone application (DizzyFIX; Clearwater Clinical Ltd, Ottawa, Ontario, Canada) by medical students had a significant impact on the pe...

Motion planning has received much attention over the past 40 years. More than 15 years have passed since the introduction of the successful sampling-based approach known as the Probabilistic RoadMap Method (PRM). PRM and its many variants have demonstrated great success for some high-dimensional problems, but they all have some level of difficulty in the presence of narrow passages. Recently, a...

This paper introduces a fast weighted streaming spanner algorithm (WSS) that trims edges from roadmaps generated by robot motion planning algorithms such as Probabilistic Roadmap (PRM) and variants (e.g. k-PRM*) as the edges are generated, but before collision detection; no route in the resulting graph is more than a constant factor larger than it would have been in the original roadmap. Experi...

Immature dengue virus particles undergo a dramatic conformational change upon exposure to the acidic environment of the late secretory pathway. The interactions of the E fusion proteins and prM chaperone proteins on the virus envelope are reorganized to permit prM processing by a host protease, furin, thus priming virus for fusion and infection. Here we identify a pH-dependent toggle switch tha...

The magnetic Prandtl number PrM is the ratio of viscosity to resistivity. In astrophysical disks the diffusion of angular momentum (viscosity) and magnetic fields (resistivity) are controlled by turbulence. Phenomenological models of the evolution of large scale poloidal magnetic fields in disks suggest that the turbulent magnetic Prandtl number PrM,T controls the rate of escape of vertical fie...

farm machinery managers often need to make complex economic decisions on machinery replacement. repair and maintenance costs can have significant impacts on this economic decision. the farm manager must be able to predict farm machinery repair and maintenance costs. this study aimed to identify a regression model that can adequately represent the repair and maintenance costs in terms of machine...

BACKGROUND We conducted this retrospective study to analyze the relationship between the distance of the proximal resection margin (PRM) and the pattern of recurrence in patients with gastric cancer who underwent curative gastrectomy. METHODS In our series, there were 774 patients who underwent curative gastrectomy for gastric adenocarcinoma. Thus, we classified our clinical series of patient...
