W H E N the Manhigh capsule system was being designed in the fall of 1955, the pr imary objective was a maximum performance system of minimum weight that could lift a man into a space equivalent environment for twenty-four hours. This objective 'had to be met safely and supply an answer to what the man could :do if any specific componem failed. Beyond this, an effort was made to provide him wit...

The Gibbard-Satterthwaite theorem is a cornerstone of social choice theory, stating that an onto social choice function cannot be both strategy-proof and non-dictatorial if the number of alternatives is at least three. The Duggan-Schwartz theorem proves an analogue in the case of set-valued elections: if the function is onto with respect to singletons, and can be manipulated by neither an optim...

The objectives of this study were to determine the prevalence of pawing behavior in a population of Standardbred racehorses and the relationship of pawing frequency to time of day. Standardbreds (n=41) were observed using instantaneous scan sampling twice daily, in the morning before training and in the afternoon after training. A majority of the horses, twenty-four (58.5%) of the 41 horses sho...

Twenty four remitted schizophrenics and twenty four neurotic depressives were studied on three measures of visual information processing, viz., simple reaction time, choice reaction time, and a forced choice span of apprehension test. The groups were matched for age, sex, and educational status. The remitted schizophrenics performed poorly on these measures compared to neurotic depressives. The...

We present a method of computing with matrices over very small finite fields of size larger than 2. Specifically, we show how the Method of Four Russians can be efficiently adapted to these larger fields, and introduce a row-wise matrix compression scheme that both reduces memory requirements and allows one to vectorize element operations. We also present timings which confirm the efficiency of...

We dealt in a series of previous publications with some geometric aspects of the mappings by functions obtained as analytic continuations to the whole complex plane of general Dirichlet series. Pictures illustrating those aspects contain a lot of other information which has been waiting for a rigorous proof. Such a task is partially fulfilled in this paper, where we succeeded among other things...

sitive to prolan (the anterior pituitary-like hormone), than the immature female mouse, the rat has been tried as an experimental animal for pregnancy-hormone tests. Eberson and Silverberg (1931), who used immature rats, obtained results as early as thirty-six to fortyeight hours. Walker and Walker (1938) modified the above test and reduced the time to thirty hours. Later, Kelso (1940), and Fra...

2 The first line of conjecture 5 of [1] was proven by Dembo, Cover and Thomas in Theorem 23 of [2]. The proof is a consequence of the properties of the discrete Rényi entropies, defined as R p (x) = p 1 − p/2 ln(x p /x 2) p ≥ 1 (1) where x p is the Hölder p−norm
