Conditions of high and low optic flow were generated in a display used for a driving simulator. Thirty drivers were requested to produce vehicle speeds of either 30 or 60 mph with the geometric field of view at 25, 55, or 85 visual degrees. Drivers overestimated the production of 30 by 20 mph. It was also found that the production of speed was highly dependent on the geometric field of view. Th...

PRIMARY OBJECTIVE To review of studies that focus on the assessment of driving competence among the elderly who are at increased risk of being involved in automobile crashes. The current status of neuropsychological testing as a predictor of driving safety in this population is critically evaluated. MAIN OUTCOMES AND RESULTS Several domains of neuropsychological assessment have been shown to ...

Patterned bruises are frequently noted on trauma victims. Although these bruises do not require any specific treatment, they provide objective evidence of impact. They also provide valuable clues to determining the impacting object, the mechanism of injury and have medico-legal importance. We present a case to illustrate and discuss the clinical utility of patterned bruises.

Abstract We study transverse-momentum-dependent (TMD) gluon distributions and factorization theorems for the gluon-initiated semi-inclusive processes at hadron colliders. Gauge-invariant TMD gluon distributions are defined, and their relations to the integrated (Feynman) parton distributions are explored when the transverse momentum is large. Through explicit calculations, soft-collinear factor...

ABSTRACT Little research has been conducted to understand the difference in driving performance between younger-old adults (60-75 years) and older-old adults (76+ years), or simply younger olds and older olds. The main objective of this study was to determine if a minimal increase in road light level (luminance) differently affects the performance of these two distinct age groups. Older adults...

This study investigated the degrees of consistencies in driving behavior when operating a real system (real car), a virtual system (high fidelity driving simulator), and a laboratory system (computer driving game). The same tendency of behavioral consistencies was confirmed among the three systems: i.e., the steering operation demonstrated the highest behavioral consistencies, followed by the a...

The main objective of this study was to determine if a minimal increase in road light level (luminance) could lead to improved driving performance among older adults. Older, middleaged and younger adults were tested in a driving simulator following vision and cognitive screening. Comparisons were made for the performance of simulated night driving under two road light conditions (0.6 and 2.5 cd...
