Composable memory transactions

by Tim Harris, Mark Plesko, Avraham Shinnar, David Tarditi - In Symposium on Principles and Practice of Parallel Programming (PPoPP , 2005
"... Atomic blocks allow programmers to delimit sections of code as ‘atomic’, leaving the language’s implementation to enforce atomicity. Existing work has shown how to implement atomic blocks over word-based transactional memory that provides scalable multiprocessor performance without requiring changes ..."
Abstract - Cited by 509 (43 self) - Add to MetaCart
repeatedly in an atomic block), (3) we use runtime filtering to detect duplicate log entries that are missed statically, and (4) we present a series of GC-time techniques to compact the logs generated by long-running atomic blocks. Our implementation supports short-running scalable concurrent benchmarks

Atmospheric Measurement Techniques Volatilizable Biogenic Organic Compounds (VBOCs) with two dimensional Gas Chromatography-Time of Flight Mass Spectrometry (GC×GC-TOFMS): sampling methods, VBOC complexity, and chromatographic retention data

by J. F. Pankow, W. Luo, A. N. Melnychenko, K. C. Barsanti, L. M. Isabelle, C. Chen, A. B. Guenther, T. N. Rosenstiel , 2012
"... Abstract. Two dimensional gas chromatography (GC×GC) with detection by time-of-flight mass spectrometry (TOFMS) was applied in the rapid analysis of air samples contain-ing highly complex mixtures of volatilizable biogenic or-ganic compounds (VBOCs). VBOC analytical method-ologies are briefly review ..."

Improved Garbled Circuit Building Blocks and Applications to Auctions and Computing Minima

by Vladimir Kolesnikov, Ahmad-reza Sadeghi, Thomas Schneider - In Cryptology and Network Security (CANS , 2009
"... Abstract. We consider generic Garbled Circuit (GC)-based techniques for Secure Function Evaluation (SFE) in the semi-honest model. We describe efficient GC constructions for addition, subtraction, multiplication, and comparison functions. Our circuits for subtraction and comparison are approximately ..."
Abstract - Cited by 56 (8 self) - Add to MetaCart
are approximately two times smaller (in terms of garbled tables) than previous constructions. This implies corresponding computation and communication improvements in SFE of functions using our efficient building blocks. The techniques rely on recently proposed “free XOR ” GC technique. Further, we present concrete

Application of MLR, PLS and Artificial Neural Networks for Prediction of GC/ECD Retention Times of Chlorinated Pesticides, Herbicides, and Organohalides

by Saeid Asadpour , Mahmood Chamsaz , Md Jelas Haron
"... ABSTRACT Quantitative structure-retention relationship (QSRR) models correlating the retention times of diverse chlorinated pesticides, herbicides, and organohalides in gas chromatography/electron capture detector (GC/ECD) system and their structures were developed based on different multivariate r ..."

Real Time Chemical Process Measurements Using a Multi-port GC/SAW System

by Gary W. Watson, Edward J. Staples, Shekar Viswanathan
"... The performance of a fast gas chromatograph equipped with a Surface Acoustic Wave (SAW) detector for chemical process measurement is evaluated in this paper. The performance of the GC/SAW system is measured in terms of minimum detection levels for common volatile organic compounds (VOCs) and semi--v ..."
Abstract - Add to MetaCart
control decisions to be made, and in less time than previous techniques involving laboratory testing of process samples. The ability to monitor bio-chemical processes such as metabolism of bacteria and detecting compounds such as methyl isocyanate in real time is shown.

Effect of extraction time on antioxidants and bioactive volatile components of green tea (Camellia sinensis), using GC/MS

by Mudasir Ahmad , Waqas N Baba , Adil Gani , Touseef Ahmed Wani , Asir Gani , F A Masoodi , 2015
"... Abstract: Two green tea types, leaf grade and sanding, were extracted at different time intervals: 20, 40, and 120 min at a constant temperature of 50°C. The extracts were analyzed by GC/MS technique. The major compounds identified were myristic acid, palmitic acid, stearic acid, oleic acid, 1H-pur ..."

SSP chains: Robust, distributed references supporting Acyclic Garbage Collection

by Marc Shapiro, Peter Dickman, David Plainfossé , 1992
"... SSP chains are a novel technique for referencing objects in a distributed system. To client software, any object reference appears to be a local pointer; when the target is remote, an SSP chain adds an indeterminate number of levels of indirection. Copying a reference across the distributed system e ..."

Towards an Analysis of Garbage Collection Techniques for Embedded Real-Time Java Systems ∗

by M. Teresa Higuera-toledano
"... From a real-time perspective, the Garbage Collector (GC) introduces unpredictable pauses that are not tolerated by real-time tasks. Real-time collectors eliminate this prob-lem but introduce a high overhead. Another approach is to use Memory Regions (MR) within which allocation and deallocation are ..."

Endoscopic-Assisted Closure of Persistent Gastrocutaneous Fistula With a Porcine Fistula Plug: Report of a New Technique

by Gregory Stiegmann, Ricardo J. Gonzalez
"... Persistent gastrocutaneous (GC) fistula is a rare but problematic complication of gastrostomy feeding tube removal. Several techniques for nonoperative fistula closure have been attempted with mixed results. None has proven both satisfactorily simple and consistently effective. The authors present a ..."
