Let L/K be a nite Galois CM-extension of number elds with Galois group G. In an earlier paper, the author has de ned a module SKu(L/K) over the center of the group ring ZG which coincides with the Sinnott-Kurihara ideal if G is abelian and, in particular, contains many Stickelberger elements. It was shown that a certain conjecture on the integrality of SKu(L/K) implies the minus part of the equ...

We discuss the role of strangeness in dense matter and especially in neutron stars. The early (in density) introduction of hyperons found in many calculations is probably delayed by the decrease in vector mean field acting on the neutron. This decrease results from both conventional many-body rescattering effects and from the movement towards asymptotic freedom at high densities. Subthreshold K...

Knowles, Das Gupta and Sen (1936) have observed that 15 of a batch of 31 white mice (Mus muscuius) showed spontaneous infection with Spirillum minus. These mice were caged in cages of narrow meshed iron-netting. No rat could possibly get at the mice to bite them. On looking through the literature it is found that other workers such as Robertson (1930), McCluskie (1930), and lately Francis (1936...

George A. Miller said that human beings have only seven chunks in short-term memory, plus or minus two. We counted the number of bunsetsus (phrases) whose modifiees are undetermined in each step of an analysis of the dependency structure of Japanese sentences, and which therefore must be stored in short-term memory. The number was roughly less than nine, the upper bound of seven plus or minus t...

Microtubules are intrinsically polar structures. A consequence of this polarity is that the two ends of the microtubule polymer exhibit different properties. The more dynamic plus ends and the mechanisms that regulate their behavior have been the focus of much recent attention. Here, we concentrate on the dynamics and regulation of minus ends, which play distinct but equally critical roles in m...

Bromoviral templates for plus-strand RNA synthesis are rich in A or U nucleotides in comparison to templates for minus-strand RNA synthesis. Previous studies demonstrated that plus-strand RNA synthesis by the brome mosaic virus (BMV) RNA replicase is more efficient if the template contains an A/U-rich template sequence near the initiation site (K. Sivakumaran and C. C. Kao, J. Virol. 73:6415-64...

OBJECTIVES The purpose of this study was to evaluate an implantable cardioverter-defibrillator (ICD) incorporating biventricular pacing. BACKGROUND Biventricular pacing improves the symptoms of heart failure, a frequent problem in ICD recipients. METHODS This prospective multicenter study evaluated the safety and efficacy of an ICD with biventricular pacing. RESULTS A total of 84 patients...
