The temperature dependence of 35C1 NQR frequencies in 4,4'-dichlorobenzophenone was mea­ sured between 9.3 and 372 K by the pulse Fourier-transform method. Successive phase transitions were observed at 189 and 194 K. Concerning these phase transitions, the curious thermal hysteresis phenomenon found in a previous NQ R experiment was not reproduced in the present study. It also follows that NQ R...

We present an O(n)-time randomized approximation algorithm for the maximum traveling salesman problem whose expected approximation ratio is asymptotically 251 331 , where n is the number of vertices in the input (undirected) graph. This improves the previous best.

We study edge dynamics in the presence of interlayer tunneling, parallel magnetic field, and various types of disorder for two infinite sequences of quantum Hall states in symmetric bilayers. These sequences begin with the 110 and 331 Halperin states and include their fractional descendants at lower filling factors; the former is easily realized experimentally while the latter is a candidate fo...

Chromogranin B (CgB), a major member of the chromogranin/secretogranin family of catecholamine storage vesicle secretory proteins, plays both intracellular (vesiculogenic) and extracellular (prohormone) roles in the neuroendocrine system, and its biosynthesis and release are under the control of efferent sympathetic nerve traffic ("stimulus-transcription coupling"). To explore the role of hered...
