The 0-1 knapsack problem (KP) is one of the classical NP-hard problems with binary decision variables. The traditional differential evolution (DE) is an effective stochastic parallel search evolutionary algorithm for global optimization based on real valued crossover and mutation operations in continuous space. To solve KPs, based on DE, a discrete binary(More)
The resource planning and scheduling technology of payload is a key technology to realize an automated control for earth observing satellite with limited resources on satellite, which is implemented to arrange the works states of various payloads to carry out missions by optimizing the scheme of the resources. The scheduling task is a difficult constraint(More)
OBJECTIVE To evaluate the treatment efficacy and tolerance of anti-human T lymphocyte porcine immunoglobulin (p-ALG) plus cyclosporine A (CsA) in acquired severe aplastic anemia (SAA). METHOD Forty-eight SAA patients [31 males and 17 females; 17 with very SAA (VSAA)] were treated with p-ALG plus CsA and were analyzed retrospectively according to early(More)
A rapid, convenient and reliable pseudorabies virus (PRV) detection system was developed by using the loop-mediated isothermal amplification (LAMP) method. Six special primers were designed successfully based on the PRV DNA-binding protein (DBP) gene. The assay was optimized to amplify PRV DNA by incubation at 63 degrees C for 1h. The LAMP products had a(More)
BACKGROUND Pulmonary hypertension (PH) is a common complication of congenital heart disease and pulmonary vascular structural remodeling due to the high pulmonary blood flow is considered as the key pathologic process. In the present study the effects of L-arginine on the collagen metabolism of pulmonary arteries in rats with high pulmonary blood(More)
PURPOSE To evaluate the effectiveness and safety of a new double fixation technique for displaced patellar fractures using bioabsorbable cannulated lag screws and braided polyester suture tension bands. METHODS Fifteen patients (mean age of 46.2 years) with displaced transverse or comminuted patella fractures were enrolled in this prospective study. All(More)
In the field of regenerative medicine, human mesenchymal stem cells envisage extremely promising applications, due to their ability to differentiate into a wide range of connective tissue species on the basis of the substrate on which they grow. For the first time ever reported, we investigated the effects of a thin film of pegylated multiwalled carbon(More)

A modified genetic particle swarm optimization method (MGPSO) is employed to solve the capacitated vehicle routing problems (CVRP). MGPSO was derived from the standard particle swarm optimization (PSO) and incorporated with the genetic reproduction mechanisms, namely crossover and mutation. MGPSO employs an integer encoding and decoding representation,(More)

With the rapid development of multi-agent based E-commerce systems, on-line automatic negotiation protocol is often needed. But because of incomplete information agents have, the efficiency of on-line negotiation protocol is rather low. To overcome the problem, an on-line agent bilateral multi-issue alternate bidding negotiation protocol based on(More)
Landing gear of aircraft is the key component. The magneto-rheological (MR) damper applied to landing gear can ensure stability and safety during the process of takeoff, landing and rollout. Because of landing gear is a nonlinear, multivariate and multi-degree of freedom system. The traditional PID control can't obtain ideal control effects. Based on the(More)
