In this paper, we present a novel prism with the ability to enhance the contrast ratio and maintain the optical efficiency in a digital light processing projection system. The working theorem for the novel prism is derived as well. In this novel prism design, the ghost ray is directed away from the projection lens by a total internal reflection surface. Since the ghost ray does not even enter t...

A video coding paradigm called PRISM (Power-efficient, Robust, hIgh compression, Syndrome-based Multimedia coding) built on distributed source coding principles has been recently proposed in [1]. In this paper, we study a scalable version of PRISM which addresses both spatial and temporal scalability. The proposed codec inherits the main attributes of the PRISM architecture, namely increased ro...

Preface The past several years have witnessed a tremendous interest in logic-based probabilistic learning as testified by the number of formalisms and systems and their applications. Logic-based probabilistic learning is a multidisciplinary research area that integrates relational or logic formalisms, probabilistic reasoning mechanisms, and machine learning and data mining principles. Logic-bas...

This paper presents a tunable optofluidic prism based on the configuration of two laminar flow streams with different refractive indices in a triangular chamber. The chambers with 70 and 90 apex angles are designed based on simulation results, which provide the optimum working range and avoid recirculating flows in the chambers. In addition, a hydrodynamic model has been developed to predict th...

The space-time prism demarcates locations that a mobile object can occupy given origin and destination anchors, the earliest origin departure and the latest destination arrival time, and the maximum travel velocity n Lenntorp 1976). The prism boundary has been used widely to delimit individual ’ accessibility (Miller 1991, Kwan 1998, Geurs and Wee 2004). However, little attention has been paid ...

Vibrio cholerae is an aquatic gram-negative microbe responsible for cholera, a pandemic disease causing life-threatening diarrheal outbreaks in populations with limited access to health care. Like most pathogenic bacteria, V. cholerae secretes virulence factors to assist colonization of human hosts, several of which bind carbohydrate receptors found on cell-surfaces. Understanding how pathogeni...

OBJECTIVE The purpose of this study was to investigate the reliability of a new semistructured diagnostic interview, the Psychiatric Research Interview for Substance and Mental Disorders (PRISM), for substance-abusing patients. The reliability of psychiatric diagnoses for individuals who drink heavily or use drugs has been shown to be problematic. The PRISM was designed to improve the reliabili...

Previous work has shown that various symptoms of unilateral neglect, including the pathological shift of the subjective midline to the right, may be improved by a short adaptation period to a prismatic shift of the visual field to the right. We report here, in two neglect patients the improvement of imagery neglect after prism exposure. Despite a strong neglect observed for mental images, as we...

Disclosure of the NSA’s PRISM program demonstrated that Internet companies have become prime targets of government surveillance. But what role do companies themselves play in putting users’ privacy at risk? By comparing the changes in the privacy policies of ten companies—the nine in PRISM plus Twitter—I seek to understand how users’ privacy shifted. Specifically, I study how company practices ...

High intensity and high quality muon beams are needed for next generation lepton flavour violation experiments. Such beams can be produced by sending a short proton pulse to a pion production target, capturing the pions and performing RF phase rotation on the resulting muon beam in an FFAG ring. Such a solution was proposed for the PRISM project and this paper summarizes its current status. In ...
