By BERNARD H. CHAIKEN, CAPT., MC, USAR P ERIODIC (cyclic) neutropeisia is a chrotsic disorder of the blood, characterized by the regular recurrensce of neutrophilic gratsubocytopetsia, at approximately three week itstervals, with secondary constitutiotsal symptoms such as anorexia, malaise, atsd fever, and secotsdary insfectiotss such as stomatitis, pharytsgitis, folliculitis, lymphadetsitis, a...

Lead and its stable isotopes have been analyzed in surface water samples (0-600 m) and trapped pro'fides collected at the Bermuda Atlantic Time Series Station (U.S. Joint Global Ocean Flux Study) in April and November 1989. These results are compared with wet atmospheric lead deposition as determined from precipitation continuously collected in Bermuda since August 1988 as part of the Atmospher...

A bstract. Signal processing in the immune syst em is st udied in a t heoretical multilayered network. The elements in th e network have regular conn ectiviti es, with t he level of connectivity reflecti ng t he level of signal (cyto kine) multifunctionality. Each element opera tes by th e same nonlinear majority rule. An exact formul a for t he/ {;umber of fixed points is derived as a fun ctio...

a fundamental aspect of signal processing is filtering. Filtering involves the manipulation of the spectrum of a signal by passing or blocking certain portions of the spectrum, depending on the frequency of those portions. In this paper, Digital filters are designed using frequency specifications. Matlab provides different options for digital filter design, which includes function, calls to fil...

By M. H. F. WILKINS, M.A., PH.D. AND S. DE CARVALHO, M.D. H EME COMPOUNDS have relatively sharp absorption bands ins the visible spectrum w’hich have beers much used to identify heme enzymes ins tissue sections, e.g. the classical work of Keilins.tm These bands are, however, not sufficiently strong for consvensienst estimations of the small amounts of heme in a single cell. The Soret band, at t...

GUS is the first o f a series o f experimental computer systems that we intend to construct as part o f a program of research on language understanding. In large measure, these systems will fill the role o f periodic progress reports, summarizing what we have learned, assessing the mutual coherence o f the various lines o f investigation we have been following, and saggestin# where more emphasi...

An evaluation of four firing profiles was performed to determine the optimum processing conditions for producing high-T c Bil.8Pb0.33Srl.87Ca2Cu30 x thick films on yttriastabilized zirconia substrates. Using these four profiles, the effects of sintering temperatures of 830-850°C and soak times of 0.5 to 12 hours were examined. In this study, Tc,zero values of 100K were obtained using a firing p...
