Due to some refinements in the dynamics, we can follow the overall evolution of a realistic jet numerically till its bulk velocity being as small as βc ∼ 10c. We find no obvious break in the optical light curve during the relativistic phase itself. However, an obvious break does exist at the transition from the relativistic phase to the nonrelativistic phase, which typically occurs at time t ∼ ...

Reviews linear break-even analysis as typically outlined in textbooks on managerial economics. It is claimed that a major shortcoming of these expositions is their failure to demonstrate in what circumstances linear break-even analysis is relevant for a business and in what circumstances it is inapplicable. This article helps rectify this situation. It points out that such analysis can not be a...

We introduce ontologies (as in the Semantic Web ontology language OWL) to serve as formal description of the modeling languages of model-based systems engineering (MBSE) tools. In these tools, systems are designed via abstractions, each tool with its own conceptual modeling languages having different syntaxes and different semantics. This creates barriers in sharing these mathematical models am...

416 http://e-aair.org We have read the manuscript about codeine (3-methylmorphine) anaphylaxis by Yoo et al. with great interest and would like to take the opportunity to raise some issues and communicate our experience. As recently reviewed, despite their frequent and ubiquitous use, genuine IgE-mediated allergy to opiates remains exceedingly rare. Also, correct diagnosis is not straightforwar...

rarely, do we think of cancer as “bacterial”, such that we are often told that “cancer is not contagious” persistent bacterial infections cause persistent irritation of the host’s defense systems, which when ineffective in eradication of the infection, result in a multitude of self-destructive damages. this in some cases occurs to such severity that the resulting cellular hyper-proliferation pr...

BACKGROUND Magnetic anchored surgical instruments (MASI), relying on magnetic force, can break through the limitations of the single port approach in dexterity. Individual characteristic abdominal wall thickness (ICAWT) deeply influences magnetic force that determines the safety of MASI. The purpose of this study was to research the abdominal wall characteristics in MASI applied environment to ...

In the present study, we investigated the conditions in which rewarded distractors have the ability to capture attention, even when attention is directed toward the target location. Experiment 1 showed that when the probability of obtaining reward was high, all salient distractors captured attention, even when they were not associated with reward. This effect may have been caused by participant...

This paper describes the dimensionless groups that determine the break-up probability of droplets in a concentrated emulsion during its flow in a tapered microchannel consisting of a narrow constriction. Such channel geometry is commonly used in droplet microfluidics to investigate the content of droplets from a concentrated emulsion. In contrast to solid wells in multi-well plates, drops are m...
