Fillers are used for facial sculpturing and anti-ageing treatments with increasing popularity. The optimal outcome of any filler treatment depends upon different factors: exact indication, known limitations, filler product, and filler placement. For volumizing effect and longevity of procedures, however, the interaction of fillers and facial fat pads seems to be crucial. Here, we will review th...

We measure high resolution photoelectron angular distributions (PADs) for above-threshold ionization of xenon atoms in infrared laser fields. Based on the Ammosov-Delone-Krainov theory, we develop an intuitive quantum-trajectory Monte Carlo model encoded with Feynman's path-integral approach, in which the Coulomb effect on electron trajectories and interference patterns are fully considered. We...

Psychiatric advance directives (PADs) are legal instruments that allow competent persons to document their preferences regarding future mental health treatment and to designate a surrogate decisionmaker in the event they lose capacity to make reliable treatment decisions during an acute episode of psychiatric illness. This study reports the findings of a survey of 1,011 psychiatric outpatients ...

The popularity of parallel and distributed simulations (PADS) is increasing gradually, because they are one of the strongest techniques to simulate complex models in a scalable way. Thanks to PADS, high speedup values can be achieved and many of those complex models can be simulated in acceptable time periods. Despite this advantage, most of the engineering simulation developers cannot allocate...

OBJECTIVE To determine the extent of protective equipment use (that is, helmets, wrist guards, elbow pads, knee pads) in a representative sample of in-line skaters. SETTING Fifteen municipalities throughout the province of British Columbia. METHOD A province-wide observational survey was conducted in the summer of 1999. Skaters were observed at four types of sites (commuter, recreational, n...

BACKGROUND Increased education of girls in developing contexts is associated with a number of important positive health, social, and economic outcomes for a community. The event of menarche tends to coincide with girls' transitions from primary to secondary education and may constitute a barrier for continued school attendance and performance. Following the MRC Framework for Complex Interventio...

Herein, we use genetic data from 277 sleeper sharks to perform coalescent-based modeling to test the hypothesis of early Quaternary emergence of the Greenland shark (Somniosus microcephalus) from ancestral sleeper sharks in the Canadian Arctic-Subarctic region. Our results show that morphologically cryptic somniosids S. microcephalus and Somniosus pacificus can be genetically distinguished usin...
