The existing methods of analysis applicable to time budget data are summarised. Latent budget models, a subclass of general reduced rank models for two-way contingency tables, are most appropriate as they view each of the observed conditional distributions of interest as a mixture of a small number of conditional distributions involving a hidden variable. However, they su5er from unusually comp...

OBJECTIVE The citation number of an article gives us information about its quality and contribution to science. In this article, we aimed to find the most frequently cited article in general surgery from Turkey, and evaluate how these articles in general surgery contributed to the world literature. MATERIAL AND METHODS We used the science citation index expanded database to find the most freq...

1. In view of the large number of possible molecular targets of general anaesthetics, it is necessary to have some criteria for judging which targets are important for producing general anaesthesia and which are probably not. 2. We consider in detail two criteria: sensitivity to clinically relevant concentrations of anaesthetics and stereoselectivity to anaesthetic optical isomers. 3. The targe...

We def ine a faster algorithm functionally equivalent to the classical backtrack algorithm for assignment p rob lems , of wh ich the Eight Queens puzzle is an e l emen ta r y example (Fi l lmore & Williamson 1974, Knuth 1975 ] . Exper imental measurements (f igure 1) reveal r educ t i on by a factor of 2.5 for the 8-queens puzzle ( fac to r of 8.7 for 16 queens) in T, the number of pairtests p ...

This year marks 200 years of patient care at the Massachusetts General Hospital (MGH). In celebration of this milestone, a unique Grand Rounds case is presented. A 450-year-old rotund man admitted 60 times presents with a classic triad of periumbilical pain, bilateral plantar burns, and a frozen scalp. Although this triad may at first strike a cord of familiarity among seasoned clinicians, the ...

We have constructed the most general gauge fixing term for the SU(2) Yang-Mills theory, which leaves the global U(1) gauge symmetry intact (i.e., the most general Maximal Abelian gauge). From the viewpoint of renormalizability, we point out the importance of an additional gauge fixing parameter that is not included in the ordinary gauge fixing term with the global SU(2) gauge symmetry. By requi...
