The relationship between precipitation and large-scale measures of atmospheric circulation has received much attention in recent years (e.g. Bardossy & Caspary, 1990; Bardossy & Plate, 1992; Hughes et al., 1993; Woolhiser et al., 1993; Katz & Parlange, 1993). Some of the interest relates to quantifying the possible change in atmospheric circulation within the past two decades, with associated c...

BACKGROUND admission to a Geriatric Evaluation and Management Unit (GEMU) can optimise a patient's chance of functional recovery. OBJECTIVE to evaluate the ability of several commonly used frailty and functional decline indices to predict GEMU outcomes, both at discharge and at 6 months. DESIGN prospective, observational study. SETTING AND PARTICIPANTS consecutive GEMU patients aged ≥70 y...

An immunoenzymatic method for the detection of IgM antibodies (IgM-ELISA) against a fraction of Schistosoma mansoni adult worm antigen, soluble in trichloroacetic acid (TCA-soluble fraction), was evaluated for epidemiological purposes in low endemic areas for schistosomiasis. Blood samples on filter paper were collected from a population living in the municipality of Pedro de Toledo, São Paulo ...

Abstract Introduction Among the instruments that measure an elder’s functional dependence level, Katz Index of Independence in Activities Daily Living has advantages being neutral, easy to use, valid, and reliable. It is a six-item instrument rating level performing activities daily living, including bathing, dressing, toileting, transferring, continence, feeding. Each item can be rated nominal...

We give a concrete relation between Katz’s middle convolution and Yokoyama’s extension and show the equivalence of both algorithms using these operations for the reduction of Fuchsian systems on the Riemann sphere.

Claim 1 ZPP = RP ∩ coRP and hence ZPP ⊆ BPP. Claim 2 ZPP consists of languages L for which there exists a machine M running in expected polynomial time and for which: Pr[M(x) = χL(x)] = 1. (A machine runs in expected polynomial time if there exists a polynomial p such that for all x, the expected running time of M(x) is at most p(|x|).) Summarizing what we have so far: P ⊆ ZPP ⊆ RP ⊆ BPP. Howev...

Lawrence C. Katz died of melanoma on November 26, 2005, at the age of 48. He was amongst the most creative and influential neuroscientists of his time. His contributions were both scientific and personal, providing as much to the development of people as to scientific discovery. These affections were always inextricably intertwined, his love of scientific beauty and discovery, and his caring fo...
