BACKGROUND Laminectomy/laminotomy and foraminotomy are well established surgical techniques for treatment of symptomatic lumbar spinal stenosis. However, these procedures have significant limitations, including limited access to lateral and foraminal compression and postoperative instability. The purpose of this cadaver study was to compare bone, ligament, and soft tissue morphology following l...

Flex-Het drugs induce apoptosis in multiple types of cancer cells, with little effect on normal cells. This apoptosis occurs through the intrinsic mitochondrial pathway accompanied by generation of reactive oxygen species (ROS). The objective of this study was to determine if direct or indirect targeting of mitochondria is responsible for the differential sensitivities of cancer and normal cell...

web hosting service, web server cluster, web traffic characteristics, load balancing, scalability, performance analysis. FLEX is a new scalable "locality aware" solution for achieving both load balancing and efficient memory usage on a cluster of machines hosting several web sites [C99]. FLEX allocates the sites to different machines in the cluster based on their traffic characteristics. Here, ...

CONTEXT Certified athletic trainers can choose different types of external compression (none, Flex-i-Wrap, and elastic wrap) when applying an ice bag to the body. However, which type facilitates the greatest magnitude of tissue cooling is unclear. OBJECTIVE To compare the effects of 2 common types of external compression on the magnitude of surface and intramuscular cooling during an ice-bag ...

FLEX is a new scalable \locality aware" solution for achieving both load balancing and e cient memory usage on a cluster of machines hosting several web sites [1, 2]. FLEX allocates the sites to di erent machines in the cluster based on their tra c characteristics. Here, we propose a set of new methods and algorithms (Simple+, Advanced, and Advanced+) to improve the allocation of the web sites ...

We measured the contact areas and contact stresses at the post-cam mechanism of a posterior-stabilised total knee arthroplasty when a posterior force of 500 N was applied to the Kirschner Performance, Scorpio Superflex, NexGen LPS Flex Fixed, and NexGen LPS Flex Mobile knee systems. Measurements were made at 90 degrees, 120 degrees, and 150 degrees of flexion both in neutral rotation and 10 deg...

CADAL has been open to the public for more than two years. We have received a lot of positive feedbacks to improve the usability of CADAL portal. In this paper, we present our works in improving the usability of book search, reading and reporting services in CADAL portal. First, we present a quick book search application whose effective hybrid ranking mechanism combines content similarities wit...
