The heterogeneous design of multi-core processors, such as the Cell processor, introduced new challenges in porting high-level languages. Our project is developing tools that hide the underlying details of the Cell processor and eases parallel programming. We present a Virtual SIMD machine (VSM) paradigm that can be used to parallelize array expression automatically. The novelty is the use of a...

Endothelium-dependent vasodilators, nitrates, and atrial natriuretic factor relax blood vessels by increasing vascular cyclic guanosine monophosphate (cGMP). The mechanisms by which cGMP relaxes vascular smooth muscle (VSM) are not known. Since contraction of VSM is associated with increased intracellular calcium and pH, we hypothesized that cGMP may decrease vascular tone by lowering ionized, ...

This chapter considers the usefulness of the Viable System Model (VSM) in information systems (IS) projects. The VSM is a rigorous organizational model which was developed from the study of cybernetics and has been given considerable attention by management science research. The chapter presents a case study that focuses upon the sales team of a manufacturing company. This sales team were seeki...

Conventional vector-based Information Retrieval (IR) models: Vector Space Model (VSM) and Generalized Vector Space Model (GVSM) represents documents and queries as vectors in a multidimensional space. This high dimensional data places great demands on computing resources. To overcome these problems, Latent Semantic Indexing (LSI), a variant of VSM, projects the documents into a lower dimensiona...

Rapid, reflex-like stepping movements are a prevalent and functional compensatory reaction to destabilization, however, little is known about the underlying control. In this paper, a model is developed to examine how speed and stability demands affect control of foot placement during forward and backward compensatory stepping reactions. The concept of the velocity stability margin (VSM) is intr...

Recent experimental studies have shown significant alterations of the vascular smooth muscle (VSM) tone when an artery is subjected to an elevation in pressure. Therefore, the VSM participates in the adaptation process not only by means of its synthetic activity (fibronectins and collagen) or proliferative activity (hypertrophy and hyperplasia) but also by adjusting its contractile properties a...

Chronic hypoxia (CH) results in reduced sensitivity to vasoconstrictors in conscious rats that persists upon restoration of normoxia. We hypothesized that this effect is due to endothelium-dependent hyperpolarization of vascular smooth muscle (VSM) cells following CH. VSM cell resting membrane potential was determined for superior mesenteric artery strips isolated from CH rats (PB = 380 torr; 4...

Video self-modeling (VSM) is a type of intervention that has been developed to assist students in viewing themselves successfully in a wide variety of domains. The present study was designed to analyze the effects of VSM on children with autism spectrum disorder in an academic setting, with specific focus on improving on-task behavior and appropriate transitions. Participants were two children ...

Hofstede’s cultural model has been widely used to make sense of the differences seen in cross-cultural HCI research.Hofstede’s Value Survey Module (VSM) and the cultural indices it produces are well known in the HCI community. This paper reports on a recent re-examination of the VSM (specifically, VSM94) in nine countries. Contrary to expectations, the data collected did not replicate Hofstede’...

The current study investigated the effects of a Video Self-Modeling (VSM) intervention on the compliance and aggressive behavior of three children placed in a psychiatric hospital. Each participant viewed brief video clips of himself following simple adult instructions just prior to the school's morning session and the unit's afternoon free period. A multiple baseline design across settings was...
