Signalized urban intersections are key components of transportation networks. They traditionally viewed and designed as primarily motorized traffic facilities, thus their physical operational designs have aimed at maximizing throughput subject to constraints dictated by vehicular safety requirements pedestrian crossing needs. Seen from a holistic viewpoint, hubs or effective centers community a...

A great number of investigations on person characterization rely on the assessment of the Big-Five personality traits, a prevalent and widely accepted model with strong psychological foundation. However, in the context on characterizing unfamiliar individuals from their voices only, it may be hard for assessors to determine the Big-Five traits based on their first impression. In this study, a 2...

We report on the current state and important older findings of empirical studies on corporate credit ratings and their relationship to ratings of other entities. Specifically, we consider the results of three lines of research: The correlation of credit ratings and corporate default, the influence of ratings on capital markets, and the determinants of credit ratings and rating changes. Results ...

We propose a new chemical detection technique in which an analyte's vibrational frequencies are interrogated directly using an array of nanomechanical resonators. This "nanomechanical resonance spectroscopy" (NRS) could permit label-free chemical detection, combining the high sensitivity of nanomechanical approaches with the high selectivity of traditional spectroscopy. A computational proof of...

IN PREVIOUS studies [l] it has been established that a cluster of social events requiring change in ongoing life adjustment is significantly associated with the time of illness onset. Similarly, the relationship of what has been called ‘life stress,’ ‘emotional stress,’ ‘object loss,’ etc. and illness onset has been demonstrated by other investigations [2-131. It has been adduced from these stu...
