to prevent it through improvements in hygiene, diet and clothing; enormous problems which were the heartfelt concern of the three thoughtful and conscientious physicians. The extracts also emphasize that improvements were not only delayed by conservatism and by administrative red-tape, but also because sound empirical observations were often frustrated by incorrect theory. One ofthe greatest hi...

title ‘... from sceptic to convert’ [3] . By then, the epidemiological research that David Barker had initiated was maturing from ecological observations to cohorts with primary data collection, improved follow-up rates and better control for confounding, along with an expanding series of rich interdisciplinary investigations. Owing to the fertile ground laid by Professor Barker, we and numerou...

Tularemia is a serious, potentially life threatening zoonotic disease. The causative agent, Francisella tularensis, is ubiquitous in the Northern hemisphere, including Alaska, where it was first isolated from a rabbit tick (Haemophysalis leporis-palustris) in 1938. Since then, F. tularensis has been isolated from wildlife and humans throughout the state. Serologic surveys have found measurable ...

Hans Meinhardt, a pioneer in the field of theoretical biology, died on 11 February 2016 in Tübingen. He made numerous important contributions to developmental biology by spearheading the use of mathematical models to investigate the logic of patterning in complex biological systems. His work expanded our understanding of the mechanisms behind diverse biological processes, from the generation of...

Lou Gehrig was one of the most talented baseball players of all time; yet he is also remembered for ALS, the disease that took his life and still bears his name as its eponym. There is speculation about when his symptoms began. Some authorities believe that Gehrig showed signs of ALS when he starred in the film Rawhide in January 1938, which would mean that he played the entire 1938 season with...

This document describes a one-time password authentication system (OTP). The system provides authentication for system access (login) and other applications requiring authentication that is secure against passive attacks based on replaying captured reusable passwords. OTP evolved from the S/KEY (S/KEY is a trademark of Bellcore) One-Time Password System that was released by Bellcore and is desc...
