The historical and contemporary population genetic structure of the chickpea Ascochyta blight pathogen, Ascochyta rabiei (teleomorph: Didymella rabiei), was determined in the US Pacific Northwest (PNW) using 17 putative AFLP loci, four genetically characterized, sequence-tagged microsatellite loci (STMS) and the mating type locus (MAT). A single multilocus genotype of A. rabiei (MAT1-1) was det...

Existing software transactional memory (STM) implementations often exhibit poor scalability, usually because of nonscalable mechanisms for read sharing, transactional consistency, and privatization; some STMs also have nonscalable centralized commit mechanisms. We describe novel techniques to eliminate bottlenecks from all of these mechanisms, and present SkySTM, which employs these techniques....

This paper addresses the problem of semantics-based maven search in research community, which means identifying a person with some given expertise. Traditional approaches either ignored semantic knowledge or temporal information, resulting in some right mavens that cannot be effectively identified because of non-occurrence of keywords and un-exploitation of time effects. In this paper, we propo...

Retrotransposon markers have been demonstrated to be powerful tools for investigating linkage, evolution and genetics diversity in plants. In the present study, we identified and cloned three full-size TRIM (terminal-repeat retrotransposon in miniature) group retrotransposon elements from apple (Malus domestica) cv. ‘Antonovka’, the first from the Rosaceae. To investigate their utility as marke...

We present an analytical performance modeling approach for concurrency control algorithms in the context of Software Transactional Memories (STMs). We consider a realistic execution pattern where each thread alternates the execution of transactional and non-transactional code portions. Our model captures dynamics related to the execution of both (i) transactional read/write memory accesses and ...

Immunosuppressed patients with solid tumor malignancies (STMs) are particularly vulnerable to herpes zoster (HZ). This study estimated the incidence of HZ and evaluated healthcare resource utilization and costs for persons with STM receiving chemotherapy with and without incident HZ.We conducted a retrospective claims study of adults with STM receiving chemotherapy between January 1, 2010 and J...

A crucial property required from software transactional memory systems (STMs) is that transactions, even ones that will eventually abort, will operate on consistent states. The only known technique for providing this property is through the introduction of a globally shared version clock whose values are used to tag memory locations. Unfortunately, the need for a shared clock moves STM designs ...

In the long-term absence of major disturbances ecosystems enter a state of retrogression, which involves declining soil fertility and consequently a reduction in decomposition rates. Recent studies have looked at how plant traits such as specific leaf mass and amounts of secondary compounds respond to declining soil fertility during retrogression, but there are no comparable studies for lichen ...

OBJECTIVES To compare Polish version of the The Saint Louis University Mental Status Examination test (SLUMS) to generally used psychometric screening tools for detecting mild cognitive impairment and dementia. METHODS The total number of 58 nursing home residents were divided into 3 groups: 1) people showing no symptoms of dementia, 2) people with mild cognitive impairment and 3) people with...

Transactional memory (TM) manages thread synchronisation to provide an illusion of atomicity for arbitrary blocks of code. There are various implementations of TM, including hardware (HTM) and software (STM). HTMs provide high performance, but are inherently limited by hardware restrictions; STMs avoid these limitations but suffer from unpredictable performance. To solve these problems, hybrid ...
