it is a great pleasure to receive two valuable comments about our article regarding sudden cardiac death (scd) in young athletes from two well known experts working in the field of preparticipation evaluation and prevention of sports injuries. we, as authors, generally agree with both authors' comments. however, some considerations should be re-emphasized here. .....

OBJECTIVE To track national population indices of recall and response among smokers and recent quitters to an ongoing national televised anti-smoking campaign in Australia. METHOD National cross sectional population telephone surveys of adults. MAIN OUTCOME MEASURES Unprompted recall of advertising; recognition of advertising; campaign attributed encouragement to quit or stay quit; unprompt...

Although most smokers want to quit, the long-term success rate of quit attempts remains low; research is needed to understand the policy and environmental influences that can increase the success of cessation efforts. This paper uses regression methods to investigate self-reported exposure to policy and environmental influences on quit attempts, maintenance of a quit attempt for at least 6 mont...

BACKGROUND Smoking prevalence differs significantly across Europe. In addition, there are considerable differences in tobacco control activities across European countries. The relationship between prevalence and policy is under-researched. The present analysis examines the motivation to change smoking behaviour across 5 different European countries that differ considerably in their tobacco cont...

On the surface, the recent mobilization of opposition to the Stop Online Piracy Act (SOPA) over the internet appears to be yet another cyberactivism success. Yet, the antiSOPA movement should have been doomed to failure for two reasons. First, the issue was too abstract to mobilize local kinship and friendship groups. Second, because mass media interests were served by the bill, mass media was ...

Glutamate-inserting ochre suppressors have been identified among late-arising, spontaneous revertants of a hisG428 mutant of Salmonella typhimurium and an argE3 mutant of Escherichia coli. The S. typhimurium suppressors mapped in the tRNA2(Glu) gene gltU at 82 min; those in E. coli were found to be in tRNA2(Glu) genes gltW at 56 min, gltU at 85 min, and gltT at 90 min.

We present the tool UFIT (Uppaal Fault Injector for Timed automata). In UFIT, we model five types of faults, namely, message loss, transient, byzantine, stuck-at, and fail-stop faults. Given the fault-free timed automata model and the selection of a type of fault, UFIT models the faults and generates the fault-affected timed automata model automatically. As a result, the designer can analyze th...

We show that the mechanism of quantum freeze of fidelity decay for perturbations with a zero time average, recently discovered for a specific case of integrable dynamics [New J. Phys. 5, 109 (2003)], can be generalized to arbitrary quantum dynamics. We work out explicitly the case of a chaotic classical counterpart, for which we find semiclassical expressions for the value and the range of the ...
