Reported herein are the cases of three infants who were born with serious intrathoracic injuries, apparently sustained at the time of the mother's involvement in a motor vehicle accident. The accidents occurred at 26th, 29th and 36th weeks of pregnancy and resulted in minimal injuries to the mothers themselves. The infants were born four weeks, three hours and two days later, respectively. Thei...

HYPOTHESIS The use of passenger compartment safety measures has not led to decreases in pediatric morbidity or mortality in our population of patients. DESIGN Retrospective review. SETTING University, tertiary care, level I trauma center. PATIENTS All patients admitted to the Trauma Center at Louisiana State University Health Science Center School of Medicine in Shreveport between July 1,...

In previous studies, the neuroprotective effect of progestrone in diffuse traumatic brain injury has been shown. This study used mifepristone (RU-486), a potent progesterone receptor antagonist, to evaluatethe hypothesis that the neuroprotective effect of progesterone in traumatic brain injury is mediated by the progesterone receptors. The ovariectomized rats were divided into 6 groups. Brain i...

We describe the vision system for Alvin, the Autonomous Land Vehicle, addressing in particuly the task of road-following. The system builds symbolic descriptions of the road and obstacle boundaries using both video and range sensors. Road segmentation methods are described for video-based road-following, along with approaches to boundary extraction and the transformation of boundaries in the im...

This paper addresses the problem of path following for mobile robots with particular emphasis on integrating the global path planning, path following and a collision avoidance scheme in a unified framework. Whereas the traditional path following algorithms aim at minimizing an error function with respect to a given path and kinematic and/or dynamic model of the robot, the problem of collision a...

This paper studies a problem of controlling trajectories of a platoon of vehicles on a highway section with advanced connected and automated vehicle technologies. This problem is very complex because each vehicle trajectory is essentially an infinite-dimensional object and neighboring trajectories have complex interactions (e.g., car-following behavior). A parsimonious shooting heuristic algori...

mathematical modeling of supply chain operations has proven to be one of the most complex tasks in the field of operations management and operations research. despite the abundance of several modeling proposals in the literature; for vast majority of them, no effective universal application is conceived. this issue renders the proposed mathematical models inapplicable due largely to the fact th...
