The goal of this study was to determine whether there is any biomechanical difference in terms of construct strength with axial loading between volar fixed-angle locking plates with threaded locking vs smooth locking pegs. The control group comprised 7 cadaveric specimens with threaded locking pegs, and the test group comprised 7 cadaveric specimens from the same donor with smooth locking pegs....

While the dominant approach to persistent storage in practice is to use a relational DBMS, there are some specialist applications that rely on object stores. The performance of these applications depends heavily on the efficiency of the object store’s concurrency control mechanism. Today’s predominant concurrency control mechanism is strict two-phase object locking. In the 80s, an interesting a...

Paper focuses on biomechanics, specifically on locking cortical bone screws in angularly stable plates used for the treatment of bone fractures in the medical fields of traumatology and orthopaedics. During extraction of titanium-alloy implants, problems are encountered in an effort to loosen some locking bone screws from the locking holes of an angularly stable plate and the subsequent strippi...

We report on stable dual-wavelength operation in passive and hybrid mode-locking of a 10GHz two-section InAs/InP(100) quantum dot laser diode operating at 1.5μm. The range of stable passive mode-locking, the locking range of hybrid mode-locking and detailed measurements of the phase modulation in the output pulses will be presented. Keywordsmode-locked laser diode; quantum dot; hybrid mode-lock...

BACKGROUND Axial dynamization of fractures can promote healing, and overly stiff fixation can suppress healing. A novel technology, termed active plating, provides controlled axial dynamization by the elastic suspension of locking holes within the plate. This prospective, controlled animal study evaluated the effect of active plates on fracture-healing in an established ovine osteotomy model. W...

A comparison equation is set up and solved for the locking of an electronic angular momentum 1 = 1 to the molecular axis during a collision of two atoms. Two parameters which enter into the comparison equation characterize the strength and the abruptness of the locking. A solution found allows one to investigate the transition from loose locking to tight locking. A new definition of the locking...

Most modern computing systems are having multicore processors with multilevel caches for high performance. Caches increase total power consumption and worsen execution time unpredictability. Studies show that way (or partial) cache locking may improve timing predictability and performance-to-power ratio for both single-core and multicore systems. Even though both private first-level and shared ...

BACKGROUND Working memory (WM) deficits are a core feature of schizophrenia. Recent electrophysiological evidence indicates that the brain systems for visual encoding are especially impaired. However, patients still achieve performance levels clearly above chance, which indicates the existence of residual mechanisms supporting WM encoding. The present study presents evidence that alpha phase lo...
