Functional programming is a good idea, but we haven’t got it quite right yet. What we have been doing up to now is weak (or partial) functional programming. What we should be doing is strong (or total) functional programming in which all computations terminate. We propose an elementary discipline of strong functional programming. A key feature of the discipline is that we introduce a type disti...

Birdshot retinochoroidopathy (BSRC) is a distinct type of posterior uveitis originally described in the 1940s. Its characteristics include minimal anterior segment inflammation and diffuse posterior choroidopathy with vitritis and retinal vasculitis. The precise etiology of this disease is yet to be elucidated. However, various treatment modalities have been employed with the ultimate goal of d...

Are Student Exchange Programs Worth It? The number of university students participating in exchange programs has risen sharply over the last decade, but a survey of Swiss university graduates (class of 1999 and 2001) shows that participation in student exchange programs significantly prolongs the period of time spent studying at university. Given this fact, the advantages of exchange programs f...

The cerebral metabolic activity of glucose and ketones was compared in ketotic rats with insulin-dependent diabetes mellitus (IDDM) and in normal controls. In the IDDM rats, ketosis had been present < 12 hours and the diabetes was of recent onset. After sufficient infusion of labeled [1-13C]glucose to achieve steady-state levels, the ratio of the fractional enrichment of the metabolites [4-13C]...

The Surveillance Research Program of the American Cancer Society's Department of Epidemiology and Surveillance Research reports its 33rd annual compilation of cancer frequency, incidence, mortality, and survival data for the United States.

Cell migration is a fundamental process that occurs during embryo development. Classic studies using in vitro culture systems have been instrumental in dissecting the principles of cell motility and highlighting how cellsmake use of topographical features of the substrate, cell-cell contacts, and chemical and physical environmental signals to direct their locomotion. Here, we review the guidanc...
