We formulate Dempster Shafer Belief functions in terms of Propositional Logic, using the im­ plicit notion of provability underlying Demp­ ster Shafer Theory. The assignment of weights to the propositional literals enables the Belief functions to be explicitly computed using Net­ work Reliability techniques. Also, the updat­ ing of Belief functions using Dempster's Rule of Combination correspon...

The effects of in vitro incubation of three henzimidazole anthelmintics, thia­ bendazole, mebendazole and cambendazole on Strongyloides were compared. No drug affected hatching of S. ratti eggs or the viability of infective larvae or para­ sitic adult worms, but all three inhibited moulting of S. ratti larvae. In addition, cambendazole, but not thiabendazole or mebendazole, impaired the viabili...

We define a new notion of conditional belief, which plays the same role for Dempster­ Shafer belief functions as conditional probability does for probability functions. Our definition is dif­ ferent from the standard definition given by Demp­ ster, and avoids many of the well-known problems of that definition. Just as the conditional prob­ ability Pr(·IB) is a probability function which is the ...

Laser-induced fluorescence has been used to measure tissue levels of chloroaluminum sulfonated phthalocyanine in vivo in an implanted ham ster cheek pouch carcinoma tumor model. The drug was excited at 610 nm via a pulsed nitrogen laser-pumped dye laser, and fluorescence intensity was monitored at 684 nm for up to 30 days after drug administration. Data were acquired noninvasively with high tem...

Chromosomes from successive passages of a Chinese ham ster cell strain (WCHE/5) that spontaneously progressed from a euploid primary cell culture to a heteroploid tumorigenic cell line were isolated and analyzed by Giemsa banding and high-reso lution flow karyotype analysis. The frequency and identification of aneuploid and marker chromosomes were determined at both preand postcrisis culture st...

The effect of various sulfhydryl compounds on the survival of exponentially growing monolayer cultures of Chinese ham ster cells (HA1 ) heated to temperatures of 37-43° was exam ined. Concentrations of cysteamine which were nontoxic or minimally toxic at room temperature or 37° became increas ingly toxic at elevated temperatures, greatly potentiating the killing produced by heat alone in the ...

, . In course of time he joined the Bristol Medical School, ?lng most of his clinical work at the Royal Infirmary, and 0 taming the diplomas of M.R.C.S., L.R.C.P. in 1891. For a short time he was engaged in private practice, and as Medical Officer to the Bristol Foresters for two years. He acted as assistant medical officer in mental hospitals at ^ster and Maidstone, at which institutions he la...

He was diseharged fromii miilitary duty in 1946. In January, 1955, he experienced dyspnea of increased severity, orthopnea, and marked fatigue. At no timne did he have pain in his chest. Examination in May 1955, revealed the presen...
