This paper considers the synchronized output regulation (SOR) problem of nonlinear multi-agent systems with switching graph. The SOR means that all agents regulate their outputs to synchronize on the output of a predefined common exosystem. Each agent constructs its local exosystem with the same dynamics as that of the common exosystem and exchanges the state information of the local exosystem....
Vietnamese word segmentation (VWS) is a challenging basic issue for natural language processing. This paper addresses the problem of how does dictionary size influence VWS performance, proposes two novel measures: square overlap ratio (SOR) and relaxed square overlap ratio (RSOR), and validates their effectiveness. The SOR measure is the product of dictionary overlap ratio and corpus overlap ra...
In this paper we give the optimum parameters for the Accelerated Overrelaxation (AOR) method in the special case where the matrix coefficient of the linear system, which is solved, is consistently ordered with nonvanishing diagonal elements. Under certain assumptions, concerning the eigenvalues of the corresponding Jacobi matrix, it is shown that the optimum AOR method gives better convergence ...
■ EVIDENCE-BASED ANSWER For grade 3 and 4 ankle sprains, ice works better than heat to speed recovery (return to play) (strength of recommendation [SOR]: B, based on a single retrospective cohort study). No studies support faster return to play with the application of heat at any time after injury (SOR: B, based on head-to-head randomized trials). Ice therapy also reduces edema, but the clinica...
A diet high in fiber (particularly fruit and vegetable fiber) and low in fat and red meat may help to decrease the risk of symptomatic diverticular disease (strength of recommendation [SOR]: C, case-control studies and a large prospective cohort study). For people with diverticular disease, a diet high in fiber might decrease the risk of complications (SOR: C, case series). No studies have eval...
Evidence-Based Answer Surgery should not be offered to patients with asymptomatic cholelithiasis. (Strength of Recommendation [SOR]: C, based on decision analysis, observational studies, and expert opinion.) Cholecystectomy may be beneficial for patients who are at high risk of biliary cancer, infection, or other complications, including younger patients and those with choledocholithiasis, sick...
A It’s impossible to say for certain in the absence of randomized controlled trials. However, in patients whose impingement symptoms don’t improve after 3 to 6 months, arthroscopic subacromial decompression (ASD) is associated with modest (about 10%) longterm improvement in pain and function compared with open acromioplasty or baseline (strength of recommendation [SOR]: B, cohort studies). Pati...
We present the results in embedding a multigrid solver for Poisson's equation into the parallel 3D Monte Carlo device simulator, PMC-3D. First we have implemented the sequential multigrid solver, and embedded it into the Monte Carlo code which previously was using the sequential successive overrelaxation (SOR) solver. Depending on the convergence threshold, we have obtained signi cant speedups ...
Evidence-Based Answer Topical silver should not be used for treatment of nonburn wounds because it does not hasten healing. (Strength of Recommendation [SOR]: A, based on a systematic review of randomized controlled trials [RCTs].) Medical-grade topical honey can be used to reduce healing time for partial-thickness burns, but it produces no effect on lacerations, surgical wounds, chronic wounds...
Escherichia coli O157:H7 is a foodborne pathogen distinguished from typical E. coli by the production of Shiga toxins (Stx) and the inability to ferment sorbitol (SOR) and to express beta-glucuronidase (GUD) activity. An allele-specific probe for the GUD gene (uidA) and multilocus enzyme electrophoresis were used to elucidate stages in the evolutionary emergence of E. coli O157: H7. A point mut...
