In this paper we report and discuss the results of a radio survey in the A3571 cluster complex, a structure located in the Shapley Concentration core, and formed by the three clusters A3571, A3572 and A3575. The survey was carried out simultaneously at 22 cm and 13 cm with the Australia Telescope Compact Array, and led to the detection of 124 radio sources at 22 cm. The radio source counts in t...

Protein translocation is essential for bacterial survival and the most important translocation mechanism in bacteria is the secretion (Sec) pathway. Thus targeting Sec pathway is a promising strategy for developing novel antibacterial therapeutics. We report the design, syntheses, mechanistic studies and structure-activity relationship analyses using HQSAR and 3-D QSAR Topomer CoMFA analyses of...

The LogP model is useful for modeling and optimizing tightly synchronized parallel algorithms with regular, ordered communication patterns on active-message based systems. However, it does not account for the contention for message processing resources at a node. The LoPC model accounts for costs of contention for message processing. In this work, we validate the LoPC model’s predictions agains...

The parameters of LogP model are measured in this paper by carrying out several benchmarks. All the benchmarks are run in IBM SP2 machine using MPI libraray in Cornell Theory Center. The result shows high overhead and short hardware latency. According to this characteristic, another All-to-All communication is proposed which has much smaller number of loops while in each loop longer messages ar...

A Threshold Circuit consists of an acyclic digraph of unbounded fanin, where each node computes a threshold function or its negation. This paper investigates the computational power of Threshold Circuits. A surprising relationship is uncovered between Threshold Circuits and another class of unbounded fanin circuits which are denoted Finite Field ZP (n) Circuits, where each node computes either ...

We have monitored 102 fields of size 1′ × 1′ within ∼0.7◦ of the Galactic Center for 1200 days in the K band. Each field was centered on one of the OH/IR stars found by Lindqvist et al. (1992). Infrared colours J−K, H−K and K−L were also obtained. Periods have been determined for 80 known OH/IR stars, including 5 from Sjouwerman (1997), and a further 29 previously unknown long-period variables ...

We consider the problem of high-dimensional Ising (graphical) model selection. We propose a simple algorithm for structure estimation based on the thresholding of the empirical conditional variation distances. We introduce a novel criterion for tractable graph families, where this method is efficient, based on the presence of sparse local separators between node pairs in the underlying graph. F...
