The first paper [2] discusses software locking mechanisms that commonly protect shared resources for multi-threaded applications. This mechanism can, especially in chip-multiprocessor systems, result in a large synchronization overhead. For real-time systems in particular, this overhead increases the worstcase execution time and may void a task set's schedulability. This paper presents two hard...

Pump frequency noise coupling into a microcavity by thermo-optic locking Report Title As thermo-optic locking is widely used to establish a stable frequency detuning between an external laser and a high Q microcavity, it is important to understand how this method affects microcavity temperature and frequency fluctuations. A theoretical analysis of the laser-microcavity frequency fluctuations is...

PURPOSE To compare the penetration of the distal screws in relation to the thickness of the distal metaphysis in the polyaxial versus uniaxial volar locking plates. METHODS Records of 78 patients aged 16 to 79 years who underwent open reduction and internal fixation for distal radial fractures (n=81) were reviewed. All fracture subtypes were included. 20 men and 22 women aged 18 to 79 (mean, ...

PURPOSE To review 9 cases of mechanical failure of the volar locking plate for distal radial fractures. METHODS Records of 374 consecutive patients who underwent volar locking plating for distal radial fractures were reviewed. Mechanical failures of the volar locking plate were defined as plate breakage or bending, screw breakage or loosening, or collapse of articular fragments resulting in i...

We describe the compiler analyses of Reform Prolog and evaluate their eeectiveness in eliminating suspension and locking on a range of benchmarks. The results of the analysis may also be used to extract non-strict independent and-parallelism. We nd that 90% of the predicate arguments are ground or local, and that 95% of the predicate arguments do not require suspension code. Hence, very few sus...

We report a case of recurrent locking of the scapula in the thorax after combined lobectomy and thoracic wall resection for advanced lung cancer. The patient was a 52-year-old man with advanced spindle cell carcinoma in his right lung. He had undergone right lung lobectomy and thoracic wall excision (Th1-5). Intrathoracic repair had not been performed to address the defect in the thoracic wall....

The fracture of the proximal humerus is the second most common injury to the upper extremity. In severe fractures, surgery may be necessary which can be in the form of a locking plate holding the bones in place. This study examines the effect of including a bonegraft alongside the locking plate. ScanIP and +ScanCAD (Simpleware Ltd) were used to segment the proximal humerus from a CT scan, and t...

Three designs of hierarchical locking suitable for B-tree indexes are explored in detail and their advantages and disadvantages compared. Traditional hierarchies include index, leaf page, and key range or key value. Alternatively, locks on separator keys in interior B-tree pages can protect key ranges of different sizes. Finally, for keys consisting of multiple columns, key prefixes of differen...

A nanocapsule for safe and effective methane storage is investigated by the method of molecular dynamics. The mass content of methane in the nanocapsule reaches the value of 14.5 mass%. The nanocapsule consists of two parts: a locking chamber and a storage area. The locking chamber is the nanotube (10.10), open at one end, with a K@C(60) (1+) endohedral complex inside it. The storage area is a ...
