Because many universities lack the funds to purchase expensive parallel computers, cost effective alternatives are needed to teach students about parallel processing. Free software is available to support the three major paradigms of parallel computing. Parallaxis is a sophisticated SIMD simulator which runs on a variety of platforms.jBACI shared memory simulator supports the MIMD model of computing with a common shared memory.

Abstract:

Our goal is to implement skeletonization algorithms on distribution memory mechines. This implementation is not trivial, because we cannot apply locally thinning operators based on 26-neighborhood, sequentially or simultaneously on all the points of the image. After summarizing the problem, we describe two methodologies to implement these algorithms on MIMD machines, one based on the decomposition of the thinning operator into sub-operators, and the other based on the decomposition of the study domain (image) into sub-domains.

Linda is a coordination language inverted by David Gelernter at Yale University, which when combined with a computation language (like C) yields a high-level parallel programming language for MIMD machines.

In this paper, we address this claim by discussing C-Linda's performance in solving a particular scientific computing problem, the shallow water equations, and make comparisons with alternatives ava

Abstract:

Linda (Linda is a registered trademark of Scientific Computing Associates, Inc.) is a programming language for coordinating the execution and interaction of processes. When combined with a language for computation (such as C or Fortran), the resulting hybrid language can be used to write portable programs for parallel and distributed multiple instruction multiple data (MIMD) computers. The Linda programming model is based on operations that read, write, and erase a virtual shared memory. It is easy to use, and lets the programmer code in a very expressive, uncoupled programming style. These be

Abstract:

High Performance Fortran (HPF) was developed to support data parallel programming for single-instruction multiple-data (SIMD) and multiple-instruction multiple-data (MIMD) machines with distributed memory. The programmer is provided a familiar uniform logical address space and specifies the data distribution by directives. The compiler then exploits these directives to allocate arrays in the local memories, to assign computations to elementary processors, and to migrate data between processors when required. We show here that linear algebra is a powerful framework to encode HPF directives and

We discuss the sources of error in solving differential equations, and the resulting constraints on time steps. We also discuss the theory of a posteriori error analysis for the Galerkin finite element methods, and its implementation in error

Such evidence comes from machine-learning methods that can decode patterns of brain activity and the simultaneous administration of transcranial magnetic stimulation (TMS) to causally manipulate brain activity in specific areas and time points.

Abstract:

Background: The Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) developed a neuropsychological battery (CERAD-NP) to screen patients with Alzheimer’s dementia. Mild cognitive impairment (MCI) has received attention as a pre-dementia stage. Objectives: To delineate the CERAD-NP features of MCI and their clinical utility to externally validate MCI diagnosis. Methods: The study included 60 patients with MCI, diagnosed using the Clinical Dementia Rating, and 63 normal controls. Data were analysed employing receiver operating characteristic analysis, Linear Support Vector Machine

Abstract:

Recollection of personal events is a major activity of the human mind and is considered essential for maintaining the cohesiveness of the self-concept. Yet evidence from cognitive psychology and brain research converge to raise doubts concerning the veridicality of the events recalled. Furthermore, even information encoded and recalled correctly seems to be prone to significant and long-lasting distortion by exposure to new input at the time of retrieval. A major source of such new input is inter-personal. From early infancy, we tend to look to others as a primary source of information and may

Abstract:

The Paced Auditory Serial Addition Task (PASAT) is a neuropsychological instrument designed to measure attention, working memory and speed of information processing in a complex manner. It is currently used to evaluate different neurological diseases. the purpose of this study was to establish PASAT normative data for the healthy Italian population using the standardized methodology of Equivalents Scores. the brief PASAT auditory version included in the Multiple Sclerosis Functional Composite was administered to 146 healthy Italian participants, distributed for gender (70 men; 76 women), age (

Abstract:

HIV infection is associated with disturbances in brain function referred to as HIV-associated neurocognitive disorders (HAND). This literature review outlines the recently revised diagnostic criteria for the range of HAND from the earliest to the more advanced stages: (i) asymptomatic neurocognitive impairment; (ii) mild neurocognitive disorder; and (iii) HIV-associated dementia. Relevant literature is also reviewed regarding the differential impact upon component cognitive domains known to be affected in HAND, which in turn should ideally be targeted during clinical and neuropsychological ass

ABSTRACTIntroduction:How frequent and how clinically important are mood and behavioral symptoms among older adults with mild cognitive impairment (MCI)? Although these noncognitive behavioral symptoms (NCBS) are not represented in the diagnostic criteria for MCI, their clinical significance is increasingly recognized.Methods:To address this question, the authors identified a cohort of consecutively evaluated patients from a psychiatric hospital's outpatient memory clinic. These patients' records contained both a clinical assessment and a standardized set of evaluations including the Mini-Menta

Abstract:

Traumatic brain injury (TBI) is often associated with enduring impairments in high-level cognitive functioning, including working memory (WM). We examined WM function in predominantly chronic patients with mild, moderate and severe TBI and healthy comparison subjects behaviorally and, in a small subset of moderate-to-severe TBI patients, with event-related functional magnetic resonance imaging (fMRI), using a visualn-back task that parametrically varied WM load. TBI patients showed severity-dependent and load-related WM deficits in performance accuracy, but not reaction time. Performance of mi

Abstract:

In this study, we used high-density EEG to evaluate whether speech and music expertise has an influence on the categorization of expertise-related and unrelated sounds. With this purpose in mind, we compared the categorization of speech, music, and neutral sounds between professional musicians, simultaneous interpreters (SIs), and controls in response to morphed speech–noise, music–noise, and speech–music continua. Our hypothesis was that music and language expertise will strengthen the memory representations of prototypical sounds, which act as a perceptual magnet for morphed variants. This m
