The hybrid flow shop scheduling problem with unrelated parallel machine is a typical NP-hard combinatorial optimization problem, and it exists widely in chemical, manufacturing and pharmaceutical industry. In this work, a novel mathematic model for the hybrid flow shop scheduling problem with unrelated parallel machine(HFSPUPM) was proposed. Additionally, an effective hybrid estimation of distribution algorithm was proposed to solve the HFSPUPM, taking advantage of the features in the mathematic model. In the optimization algorithm, a new individual representation method was adopted. The(EDA) structure was used for global search while the teaching learning based optimization(TLBO) strategy was used for local search. Based on the structure of the HFSPUPM, this work presents a series of discrete operations. Simulation results show the effectiveness of the proposed hybrid algorithm compared with other algorithms. 展开更多

AIM: To study the eradication rate of Helicobacter pylori (Hp) in a group of type 2 diabetes and compared it with an age and sex matched non-diabetic group.METHODS: 40 diabetic patients (21 females, 19 males;56±7 years) and 40 non-diabetic dyspeptic patients (20females, 20 males; 54±9 years) were evaluated. Diabetic patients with dyspeptic complaints were referred for upper gastrointestinal endoscopies; 2 corpus and 2 antral gastric biopsy specimens were performed on each patient. Patients with positive Hp results on histopathological examination comprised the study group. Non-diabetic dyspeptic patients seen at the Gastroenterology Outpatient Clinic and with the same biopsy and treatment protocol formed the control group.A triple therapy with amoxycillin (1 g b.i.d), clarithromycin (500 mg b.i.d) and omeprazole (20 mg b.i.d.) was given to both groups for 10 days. Cure was defined as the absence of Hp infection assessed by corpus and antrum biopsies in control upper gastrointestinal endoscopies performed 6weeks after completing the antimicrobial therapy.RESULTS: The eradication rate was 50 % in the diabetic group versus 85 % in the non-diabetic control group (P<0.001).CONCLUSION: Type 2 diabetic patients showed a significantly lower eradication rate than controls which may be due to changes in microvasculature of the stomach and to frequent antibiotic usage because of recurrent bacterial infections with the development of resistant strains. 展开更多

Stasis of the flow of the intestinal contents,ingested material and unfavorable composition of the chylus can lead to the formation of enteroliths inside the bowel.Enterolithiasis represents a rare disorder of the gastrointestinal tract that can be associated with intermittent abdominal pain or more serious complications such as bleeding or obstruction.Enterolithiasis in Crohn' s disease represents an extremely rare condition and usually occurs only in patients with a long symptomatic history of Crohn's disease.We report an unusual case of enterolithiasis-related intestinal obstruction in a young male patient with Crohn's disease(A2L3B1 Montreal Classification for Crohn's disease 2005) undergoing emergency laparotomy and ileocoecal resection.In addition,we present an overview of the relevant characteristics of enterolithiasis on the basis of the corresponding literature. 展开更多

Objective: The aim of our study was to examine whether irradiation combined with pemetrexed can exacerbate pulmonary injury. Methods: Two groups of male Wister Rats were subjected to bilateral apex of lungs irradiation(a single dose of 12 Gy), with or without pemetrexed(20 mg/kg) by intraperitoneal injection at the same time; a third group of weightand age- matched animals were treated with pemetrexed alone, as the same dose scheme, time and root of injection. The fourth group served as control. The whole lung mounts were dissected to histological evaluation, while serum cytokine transforming growth factor-β1(TGF-β1) analysis were compared at 1, 7, 21, 35, 49 days post-irradiation after irradiation. Results: Histological examination showed a thickening of alveolar septal, accumulation of inflammatory cells. The irradiation treatment group and the radiation-chemo treatment group showed a statistically significant higher level of TGF-β1(P < 0.05) than other two groups, but there were no differences between these two irradiation groups. Conclusion: These results demonstrated that pemetrexed can not aggravate pulmonary injury and it could be safely used in concurrent or sequential radio-chemotherapy in lung adenocarcinoma. 展开更多

This paper presents a new Transmitted Reference (TR) Ultra-WideBand (UWB) receiver based on Spatial Diversity (SD), which employs Multi-Antenna Technology (MAT) to improve the performance of TR-UWB receiver. According to the amplitude of correlator output of every antenna branch, this paper analyzed the performances of the proposed TR-UWB receiver employing three different kinds of combination strategies, i.e., Maximum Ratio Combination (MRC), Equal Gain Combination (EGC), and Selective Combination (SC), which are different from conventional ones, and theoretically proved that the performance of EGC is better than MRC. Simulation results verify that when EGC is adopted and BER=10-3, increasing three antennas provides Signal to Noise Ratio (SNR) gain of about 3 dB in CM4 channel and SNR gain of about 2 dB in CM2 channel. 展开更多

The merging party merger resulting combined balance in the merging process may affect the current income tax and deferred income tax, but also may not have any effect. This paper goes through the application case on enterprises merger' merging party or purchase party tax treatment to carry on analysis, which provides the major reference for accounting theory and accounting practice circles. 展开更多

In order to make cloud users get credible, high-quality composition of services, the trust quality of service aware(TQoS-aware) based parallel ant colony algorithm is proposed. Our approach takes the service credibility as the weight of the quality of service, then calculates the trust service quality T-QoS for each service, making the service composition situated in a credible environment. Through the establishment on a per-service T-QoS initialization pheromone matrix, we can reduce the colony's initial search time. By modifying the pheromone updating rules and introducing two ant colonies to search from different angles in parallel,we can avoid falling into the local optimal solution, and quickly find the optimal combination of global solutions. Experiments show that our approach can combine high-quality services and the improvement of the operational success rate. Also, the convergence rate and the accuracy of optimal combination are improved. 展开更多
