This paper presents an overview of slow light in semiconductor heterostructures. The focus of this paper is to provide a unified framework to summarize and compare various physical mechanisms of slow light proposed and demonstrated in the past few years. We expand and generalize the discussions on fundamental limitation of slow light and the delay–bandwidth product trade-off to include gain sys...

Pertrochanteric femur fractures are successfully treated by orthopedic surgeons worldwide, but maintaining the reduction status or fixation of the greater trochanter is sometimes difficult in unstable cases in elderly patients. Several biomechanical advantages have been reported in locking plates when compared with conventional plates; locking plates provide angular and axial stability, better ...

Purpose: The aim of this follow up clinical study was to evaluate the effectiveness of 2mm, 3-dimentional locking titanium miniplates. Patients and Method: A prospective randomized clinical trial was carried out on 10 patients with mandibular fractures. The patients were evaluated for the operating time, clinical assessment of mobility after fixation, occlusion, adequacy of reduction on postope...

While the subject of SMP locking primitives has been well covered in the literature [Val][Schm][Bald][Leh], there has been relatively little discussion on the rationale and process behind the application of these locking primitives. This leads to an inverted problem where the bulk of the work in making a kernel SMP-safe lies above the locking primitives, yet there is little guidance on how and ...

Removal of locking plates in many ways poses novel challenges compared to conventional plates. None of the techniques described for the removal of locking plates are adequate for all situations. We report our experience of 27 patients from whom a total of 33 locking plates were removed. We also describe a novel technique for the removal of locking plates which in our experience could be used in...

We used phase plane analysis to identify modes of frequency locking of the 10-Hz rhythm in sympathetic nerve discharge (SND) to the cardiac cycle in urethan-anesthetized, baroreceptor-innervated cats. Frequency locking occurred in rational ratios predicted by a generic mathematical construct called the Farey tree. Both simple harmonic ratios (e.g., 1:3) and complex ratios (e.g., 2:5) comprised ...
