This study assessed which behaviour management techniques, BMTs, pediatric dentists are using, and find effective in treating patients with Autism Spectrum Disorders, ASD and identified influences which contributed to their use. Surveys were mailed and emailed to 1669 members of the American Academy of Pediatric Dentistry. Seven hundred eighty-nine (48.2%) completed surveys were returned. Nearly 60% of respondents treated children with ASD weekly or more frequently. Of the 23 listed BMTs, General Anaesthesia, Tell-Show-Do, Distraction, and Non-verbal Communication, were considered effective....

Between Hitler and Churchill exposes an unknown facet in the World War II history: the attempt of a senior official in the Polish government-in-exile to collude with the Third Reich and a successful British intelligence operation which thwarted this move in its infancy. This surprising and fascinating event is described through the personal stories of its two main protagonists, Polish Jews. One of them mediated the said Polish-German contacts, while the other assisted the British in capturing the mediator in the Middle East and murdering him there without trial. Although it reads like a...

The authors study noncompact surfaces evolving by mean curvature flow (mcf). For an open set of initial data that are $C^3$-close to round, but without assuming rotational symmetry or positive mean curvature, the authors show that mcf solutions become singular in finite time by forming neckpinches, and they obtain detailed asymptotics of that singularity formation. The results show in a precise way that mcf solutions become asymptotically rotationally symmetric near a neckpinch singularity.
