BACKGROUND Locking plate fixation is increasingly used for first metatarsophalangeal joint (MTP-I) arthrodesis. There are still few comparable clinical data regarding this procedure. In this study we aimed to compare the clinical and radiographical outcomes of crossed-screws, locking and non-locking plate fixation with lag screw for first metatarsophalangeal joint arthrodesis. METHODS A total...

In this paper a new architecture for delay locked loops will be presented.  One of problems in phase-frequency detectors (PFD) is static phase offset or reset path delay. The proposed structure decreases the jitter resulted from PFD by switching two PFDs. In this new architecture, a conventional PFD is used before locking of DLL to decrease the amount of phase difference between input and outpu...

Single-frequency operation or locking in a lateral array of three laser oscillators is studied within the composite-cavity-mode approach. We compute the regions of stable locking, which have a nontrivial shape in the plane of coupling strength versus frequency detuning. The locking regions depend drastically on the amount of amplitude-phase coupling of the lasing field that is quantified by the...

  Background: There are few studies comparing the biomechanical properties of angled blade plate and locking compression plates in supracondylar osteotomy. In the current randomized study, we prospectively compared the clinical and radiological outcomes of supracondylar osteotomy using these two plates. Methods: Forty patients with valgus knee malalignment were randomly assigned to two equal nu...

This work investigates the effect of the explicit inclusion of queueing delays due to locking overhead in a performance study of a two phase locking concurrency control method. A mean value analysis is used to calculate the system's performance measures, response time and throughput. It is found that the locking overhead's contribution to delay depends largely on the degree of page faulting act...

An ultra-wide locking range transformer-based injection-locked frequency divider (ILFD) is presented. By making use of a 4-order transformer-based resonator and an inductive gain peaking technique, the proposed ILFD can achieve high performance in terms of wide locking range and low power consumption. Fabricated in a standard 65nm CMOS process with a core area of 0.18mm, the ILFD measures a loc...

Real-time collaborative editing systems are distributed groupware systems that allow multiple users to edit the same document at the same t ime from multiple sites. A specific type of collaborative editing system is the object-based collaborative graphics editing system. f i a ditionally, locking has been used as the major concurrency control techniques in this type of system. This paper examin...

Locking is a standard technique in distributed computing and database systems used to ensure data integrity by prohibiting concurrent conflicting updates on shared data objects. Internet-based collaborative systems are a special class of distributed applications which support human-to-human interaction and collaboration over the Internet. In this paper, a novel optional and responsive fine-grai...

OBJECTIVES We aimed to further evaluate the biomechanical characteristics of two locking screws versus three standard bicortical screws in synthetic models of normal and osteoporotic bone. METHODS Synthetic tubular bone models representing normal bone density and osteoporotic bone density were used. Artificial fracture gaps of 1 cm were created in each specimen before fixation with one of two...
