Sugahara et al, in this issue of the American Journal of Neuroradiology (page 1773), compare the 2D spin-echo (2D-SE) technique with the 3D gradient-echo (3D-GE) technique after contrast injection in order to determine which sequence is superior for the evaluation of suspected leptomeningeal tumor in the spine. The authors found that the 2D-SE technique depicted the fewest lesions. The 3D-GE te...

This work attempts to enhance telepresence by empowering nonverbal communication i.e. head gestures communication with an implementation of a robotic rear-projection head device. The feature of this implementation which is considered to be novel is the containment of all the necessary components for rear-head projection within the volume of a typical human head. This provides a natural look to ...

Rear-end collisions are one of the most frequent crash types in the U.S. Pre-Collision System (PCS) have been developed to mitigate the frequency and severity of rear-end collisions. The potential effectiveness of these systems, however, depends on the driver’s state and their attempted avoidance maneuvers. This study utilized the National Motor Vehicle Crash Causation Survey (NMVCCS), a unique...

PURPOSE Rear-end crashes attribute to a large portion of total crashes in China, which lead to many casualties and property damage, especially when involving commercial vehicles. This paper aims to investigate the critical factors for occupant injury severity in the specific rear-end crash type involving trucks as the front vehicle (FV). METHODS This paper investigated crashes occurred from 2...

As part of NHTSA’s Rear Seat Occupant Protection Research Program, the Fatality Analysis Reporting System (FARS) and State Data System (SDS) for Florida, Pennsylvania and Maryland were utilized to estimate relative fatality rates and injury risk ratios between the front and rear seat passengers. In addition, a parametric study of rear-seat restraint parameters was performed to assess chest defl...

Whiplash injury resulting from rear impact is a significant issue in terms of societal cost, and the resulting pain and reduction in quality of life. The facet joints in the cervical spine have been identified as a source of pain in whiplash injuries; however, the responses of these joints are difficult to measure in vivo or in vitro. In this study, a detailed explicit FE model of the cervical ...

Key findings The results show that 77.4% of respondents rear an average of 2.97 livestock unit (LSU) per household. More than half of respondents who rear livestock (53.82%) dump livestock carcasses in the open fields. Ethnicity, age, education status, gender, livestock unit and involvement in conservation activities are the most significant predictors for the positive attitudes towards vulture...

I vividly remember how pleased I was when Circulation Research published my first papers, one on the ventricular refractory period following changes in heart rate and another on the dual inputs into the atrioventricular node, in 1969. I thought then that Circulation Research was the top journal for basic research in the cardiovascular field, and I still think so today. Many things have changed ...

Cell migration can be considered as a repeated cycle of membrane protrusion and attachment, cytoskeletal contraction and rear detachment. At intermediate and high levels of cell-substratum adhesiveness, cell speed appears to be rate-limited by rear detachment, specifically by the disruption of cytoskeleton-adhesion receptor-extracellular matrix (ECM) linkages. Often, cytoskeletal linkages fract...
