862 NOTICES OF THE AMS VOLUME 47, NUMBER 8 A pril 9, 1900, marks the birth date of H. D. Kloosterman, one of the leading Dutch mathematicians of his generation. At the University of Leiden, where he spent most of his academic life, the centenary of his birth was the occasion for a small celebration, with a discussion by several experts of Kloosterman’s work on number theory, modular forms, and ...
The breaking of the N=8 shell-model magic number in the 12Be ground state has been determined to include significant occupancy of the intruder d-wave orbital. This is in marked contrast with all other N=8 isotones, both more and less exotic than 12Be. The occupancies of the [FORMULA: SEE TEXT]orbital and the [FORMULA: SEE TEXT], intruder orbital were deduced from a measurement of neutron remova...
Assuming Active Galactic Nuclei are powered by accretion onto a massive black hole we suggest that the growth of the central black hole mass due to the matter accreted over the AGN lifetime causes evolution of the luminosity and spectrum. We show that the effective temperature of the UV continuum spectrum is likely to be anti-correlated with the black hole mass and with the luminosity. We estim...
Given a smooth projective variety X over a field k of characteristic zero, we consider the composition of the de Rham cohomology cycle class map over k from the Chow group CH q (X × k K), where K is the field of fractions of henselization A h of the local ring of a smooth closed point of a variety over the field k with an appropriate projection:
The requirement for editors of clinical pharmacology journals to maintain an overview of the peer review process for manuscripts submitted can be facilitated by use of the 8-D Assessment. The 8-D Assessment comprises peer review criteria to determine if the:1. Design of the study, 2. Diagnoses employed, 3. Drug molecules involved, 4. Dosages applied, 5. Data collected, 6. Discussion of the find...
This paper discusses the design of a ripple-folding analog to digital (AID) converter in the current mode technique, which makes the design fully compatible with standard digital CMOS processes. The AID converter, which is designed in TSMC 0.35 Fm CMOS process, achieves 8 hits of resolution at a clock frequency of 100MHz. Simulated results show that the SFDR is better than 62 dB and the DNL and...
Recently digital signal processing has become very popular in video signal processing systems. Analog-toDigital (A/D) converters in this field, namely, video A/D converters, are also popular and have been integrated into mixed-signal system LSIs. Both power consumption and power supply voltage of video A/D converters have been decreasing drastically in recent years [1], [2]. One of the applicat...
Interleukin 8 (IL-8), a member of the C-X-C branch of the chemokine superfamily, stimulated the breakdown of 1-O-[3H]alkyl-2-acyl-sn-glycero-3-phosphocholine ([3H]EAPC) and the formation of 1-O-[3H]alkyl-2-acyl-phosphatidic acid ([3H]-EAPA) in human polymorphonuclear leukocytes (PMN) in the presence of cytochalasin B. In addition, the mass of diradyl-PA was increased with similar kinetics. In t...
