KARIATH, RIYA RAJU. Performance Comparison of Software Transactional Memory Implementations. (Under the direction of Dr. Edward F Gehringer.) Software Transactional Memory (STM), an optimistic concurrency control mechanism for controlling accesses to shared memory, is a promising alternative to lockbased mutual exclusion strategies. A transaction in this context is each piece of code that execu...

We report the detection of electron spin resonance (ESR) in individual dimers stable free radical 2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPO). ESR is measured by current fluctuations a scanning tunneling microscope (ESR-STM method). The multipeak power spectra, distinct from macroscopic data, are assigned to having exchange and Dzyaloshinskii-Moriya interactions presence spin-orbit coupling. ...

Serial-order short-term memory (STM), as opposed to item STM, has been shown to be very consistently associated with lexical learning abilities in cross-sectional study designs. This study investigated longitudinal predictions between serial-order STM and vocabulary development. Tasks maximizing the temporary retention of either serial-order or item information were administered to kindergarten...

Listeria monocytogenes is a Gram-positive foodborne pathogen and the causative agent of listerosis a disease that manifests predominately as meningitis in the non-pregnant individual or infection of the fetus and spontaneous abortion in pregnant women. Common-source outbreaks of foodborne listeriosis are associated with significant morbidity and mortality. However, relatively little is known co...

We investigated the effects of the duration and type of to-be-articulated distractors during encoding of a verbal list into short-term memory (STM). Distractors and to-be-remembered items alternated during list presentation, as in the complex-span task that underlies much of working-memory research. According to an interference model of STM, known as serial order in a box (SOB; Farrell & Lewand...

This paper presents the challenges encountered in and potential solutions to designing scalable Software Transactional Memory (STM) for large-scale distributed memory systems with thousands of nodes. We introduce Global Transactional Memory (GTM), a generalized and scalable STM design supporting a dynamic programming model based on threadlevel parallelism, Single Process Multiple Data (SPMD) pa...

Strut-and-tie is a system of forces' distribution in the form of "load-path" connectivity from the applied load point to the support point. Strut-and-Tie Method (STM) has been developed based on simple truss model. STM models represent the load carrying mechanism of a structural member by approximating the flow of internal forces by means of struts representing the flow of compressive stresses ...

BACKGROUND Despite chemical similarities, ADHD stimulants and methamphetamine have distinct use patterns in the community. This study compared the characteristics of nonmedical ADHD stimulants users and methamphetamine users in a household sample. METHODS In data from the 2009-2011 National Survey on Drug Use and Health, adult and adolescent stimulant users were categorized into three mutuall...

Distributed software transactional memory (D-STM) promises to alleviate difficulties with lock-based (distributed) synchronization and object performance bottlenecks in distributed systems. Past single copy data-flow (SC) D-STM proposals keeps only one writable copy of each object in the system and are not fault-tolerant in the presence of network node/link failures in large-scale distributed s...

This paper investigates the use of Multi-Distribution Deep Neural Networks (MD-DNNs) for integrating acoustic and statetransition models in free phone recognition of L2 English speech. In Computer-Aided Pronunciation Training (CAPT) system, free phone recognition for L2 English speech is the key model of Mispronunciation Detection and Diagnosis (MDD) in the cases of allowing freely speaking. A ...
