Self-stabilizing algorithms are designed to guarantee convergence to some desired stable state from arbitrary initial states arising out of an arbitrarily large number of faults. However, in a well-designed system, the simultaneous occurrence of a large number of faults is rare. It is therefore desirable to design algorithms that are not only self-stabilizing, but also have the ability to recov...

The k-packing problem asks for a subset S of the nodes in a graph such that the distance between any pair of nodes in S is greater than k. This problem has applications to placing facilities in a network. In the current paper we present a self-stabilizing algorithm for computing a maximal k-packing in a general graph. Our algorithm uses a constant number of variables per node. This improves the...

Aim: To compare wrist function by mean of DASH score at 12 weeks in distal radial fracture patients treated operatively (ORIF group) versus those non-operatively (CAST group). Methodology: The randomized controlled trial was conducted Indus Hospital Karachi, which is a tertiary care hospital from 1st January 2017 to 30th June and the follow up taken after recruitment last patient 96 were enroll...

Dear Editor We read the article by Bagheri et al with great interest (1). We found the study interesting and comprehensive as four groups of patients, including operative and nonoperative in either pure dislocation or fracture dislocation, were compared in terms of Mayo wrist score, Grip strength, range of motion and radiographic parameters. It seems that the results were comparable to studies ...

This study examined whether the 5-week pre-operative progressive exercise rehabilitation program with weekly monitoring contributed to a significantly lower muscle activity imbalance in treatment group, both before and immediately after anterior cruciate ligament reconstruction (ACLR), as well during next 5 weeks comparison control group. Twelve professional soccer players took part (from among...

One of the indexes of stabilization pond is the presence of coliform bacteria in water and wastewater. This study aimed to determine the effect of solar light on coliform variations in stabilization pond. In this experimental study, the effect of light, pH (<7, 7.1–8, 8.1–9), and temperature (10 ºC and 30 ºC) on facultative stabilization pond was studied for six months. The sampling was accompl...

Background:  Clavicle fractures are common and usually heal without complications. In this study, we evaluated the outcomes of non-operative versus operative management of displaced fractures.   Methods:  In a prospective clinical trial study, sixty-five patients with displaced clavicle mid-shaft fractures were nonrandomly divided in two treatment groups. The first group underwent non-operative...

A number of recent works have investigated the notion of “computational fields” as a means of coordinating systems in distributed, dense and mobile environments such as pervasive computing, sensor networks, and robot swarms. We introduce a minimal core calculus meant to capture the key ingredients of languages that make use of computational fields: functional composition of fields, functions ov...

The purpose of this report was to evaluate patient outcomes after treatment of acute midshaft clavicle fractures with an intramedullary Hagie pin, including clinical results and the incidence of postoperative complications. Between 1993 and 2003, 16 patients who underwent intramedullary Hagie pin fixation of a midshaft clavicle fracture were identified. The medical records of each patient were ...
