4Path planning for mobile robot using self-adaptive learning particle swarm optimization显示文摘As a challenging optimization problem, path planning for mobile robot refers to searching an optimal or near-optimal path under different types of constrains in complex environments. In this paper, a self-adaptive learning particle swarm optimization(SLPSO) with different learning strategies is proposed to address this problem. First, we transform the path planning problem into a minimisation multi-objective optimization problem and formulate the objective function by considering three objectives: path length, collision risk degree and smoothness. Then, a novel self-adaptive learning mechanism is developed to adaptively select the most suitable search strategies at different stages of the optimization process, which can improve the search ability of particle swarm optimization(PSO). Moreover, in order to enhance the feasibility of the generated paths, we further apply the new bound violation handling schemes to restrict the velocity and position of each particle. Finally, experiments respectively with a simulated robot and a real robot are conducted and the results demonstrate the feasibility and effectiveness of SLPSO in solving mobile robot path planning problem.Guangsheng LI Wusheng CHOU 2018Science China(Information Sciences)2018,61,5:46

8Regional ozone pollution and key controlling factors of photochemical ozone production in Pearl River Delta during summer time显示文摘An intensive field campaign including measurements from the environmental monitoring network and from two super sites took place in the Pearl River Delta region in summer 2006.Using routinely measured O3 and NOx concentrations,the spatial and temporal variation of O3 and of the total oxidant concentrations was characterized.According to the spatial variability of NO2/NO,the two super sites were found to be representative of polluted urban and downwind suburban conditions.In addition,both sites were located in high O3 regions.In-depth diagnostic of photochemical ozone production processes and their key controlling factors are achieved with an observation-based model(OBM) to gain regional perspectives.Budget analysis and sensitivity model runs show that aldehyde and HONO chemistry had significant impacts on local photochemical ozone production rates.The analysis of calculated Relative Incremental Reactivities shows that photochemical ozone production rates are mainly sensitive to anthropogenic hydrocarbons(HCs) in the polluted urban areas.In the suburban areas,sensitivity to nitrogen oxide(NO) concentrations dominated.Key anthropogenic HCs in both areas are alkenes and aromatics.Significant differences of ozone production efficiencies are identified between the urban and suburban regions,consistent with the OBM diagnosed results.CHANG ChihChung CHOU C.K.Charles Andreas Wahner 2010Science China Chemistry2010,53,3:34

12Short-chain fatty acids act as antiinflammatory mediators by regulating prostaglandin E_2 and cytokines显示文摘AIM:To investigate the effect of short-chain fatty ac-ids (SCFAs) on production of prostaglandin E2 (PGE2),cytokines and chemokines in human monocytes.METHODS:Human neutrophils and monocytes were isolated from human whole blood by using 1-Step Polymorph and RosetteSep Human Monocyte Enrich-ment Cocktail,respectively. Human GPR41 and GPR43 mRNA expression was examined by quantitative real-time polymerase chain reaction. The calcium flux assay was used to examine the biological activities of SCFAs in human neutrophils and monocytes. The effect ofSCFAs on human monocytes and peripheral blood mononuclear cells (PBMC) was studied by measuring PGE2,cytokines and chemokines in the supernatant. The effect of SCFAs in vivo was examined by intraplantar injection into rat paws.RESULTS:Human GPR43 is highly expressed in human neutrophils and monocytes. SCFAs induce robust calcium flux in human neutrophils,but not in human monocytes. In this study,we show that SCFAs can in-duce human monocyte release of PGE2 and that this effect can be enhanced in the presence of lipopolysac-charide (LPS). In addition,we demonstrate that PGE2 production induced by SCFA was inhibited by pertussis toxin,suggesting the involvement of a receptor-mediated mechanism. Furthermore,SCFAs can specifi cally inhibit constitutive monocyte chemotactic protein-1 (MCP-1) production and LPS-induced interleukin-10 (IL-10) production in human monocytes without affecting the secretion of other cytokines and chemokines examined. Similar activities were observed in human PBMC for the release of PGE2,MCP-1 and IL-10 after SCFA treatment. In addition,SCFAs inhibit LPS-induced production of tumor necrosis factor-α and interferon-γ in human PBMC. Finally,we show that SCFAs and LPS can induce PGE2 production in vivo by intraplantar injection into rat paws (P < 0.01). CONCLUSION:SCFAs can have distinct antiinflammatory activities due to their regulation of PGE2,cytokine and chemokine release from human immune cells.Mary Ann Cox James Jackson Michaela Stanton Alberto Rojas-Triana Loretta Bober Maureen Laverty Xiaoxin Yang Feng Zhu Jianjun Liu Suke Wang Frederick Monsma Galya Vassileva Maureen Maguire Eric Gustafson Marvin Bayne Chuan-Chu Chou Daniel Lundell Chung-Her Jenh 2009World Journal of Gastroenterology2009,15,44:30

15Thalidomide-based multidisciplinary treatment for patients with advanced hepatocellular carcinoma:A retrospective analysis显示文摘AIM:To evaluate the efficacy of thalidomide in combination with other therapies to treat patients with advanced hepatocellular carcinoma (HCC).METHODS:We performed a retrospective analysis of all patients with HCC who were treated with thalidomide for at least two months.The medical records of patients with HCC who were treated at our institution between April 2003 and March 2008 were reviewed.Image studies performed before and after treatment,tumor response,overall survival,and the decrease in α-fetoprotein (AFP) levels were evaluated.RESULTS:A total of 53 patients with HCC received either 100 or 200 mg/d of thalidomide.The patient population consisted of 9 women and 44 men with a median age of 61 years.Thirty patients (56.6%) were classified as Child-Pugh A,and 12 patients (22.6%) were classified as Child-Pugh B.Twenty-six patients had portal vein thrombosis (49.1%),and 25 patients had extrahepatic metastasis (47.1%).The median duration of thalidomide treatment was 6.0 mo.Six of the 53 patients achieved a confirmed response (11.3%),one achieved a complete response (1.9%) and 5 achieved a partial response (9.4%).The disease control rate (CR + PR + SD) was 28.3% (95% CI:17.8-42.4),and the median overall survival rate was 10.5 mo.The 1-and 2-year survival rates were 45% and 20%,respectively.Only one complete response patient showed an improved overall survival rate of 66.8 mo.Sixteen patients (30.2%) showed more than a 50% decrease in their serum AFP levels from baseline,indicating a better response rate (31.3%),disease control rate (43.8%),and overall survival time (20.7 mo).The therapy was well tolerated,and no significant toxicities were observed.CONCLUSION:Thalidomide was found to be safe for advanced HCC patients,demonstrating anti-tumor activity including response,survival,and AFP decreases of greater than 50% from baseline.Yang-Yuan Chen Hsu-Heng Yen Kun-Ching Chou Shun-Sheng Wu 2012World Journal of Gastroenterology2012,18,5:25
16Thermodynamics and kinetics of phase transformation in rare earth–magnesium alloys:A critical review显示文摘Magnesium and its alloys are significant superior metallic materials for structural components in automobile and aerospace industries due to their excellent physicomechanical properties.The Mg–rare earth(RE)systems have attracted great interests because RE additions can improve both the deformability and the strength of Mg alloys through solid solution strengthening and precipitation hardening mechanisms.This paper focuses on the interface stability,together with thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases in Mg–RE alloys.In this paper,the theory and recent advances on Mg–RE alloys,especially for the interface stability,thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases,together with their relationships with micro-structures,and macroscopic properties,are reviewed.By combining the thermodynamics/kinetics integrated simulations with various advanced experimental techniques,“reverse”design of Mg–RE alloys starting from the target service performance is put forward as a kind of scientific paradigm with rational design.Qun Luo Yanlin Guo Bin Liu Yujun Feng Jieyu Zhang Qian Li Kuochih Chou 2020Journal of Materials Science & Technology2020,44,9:26
17Adhesive small bowel obstruction: How long can patients tolerate conservative treatment?显示文摘AIM: To evaluate how long patients with small bowel obstruction caused by postoperative adhesions can tolerate conservative treatment.METHODS: The records of patients with small bowel obstruction due to postoperative adhesions were retrospectively reviewed. Data collected included the number of admissions, type of management for each admission,duration of conservative treatment, number of repeat laparotomies, and operative findings.RESULTS: One hundred fifty-five patients with this condition from January 1999 to December 2001, for a total of 293 admissions were enrolled in this study. Medical treatment alone was given in 220 admissions, and repeat laparotomy was performed in 73 admissions. The period of observation in patients managed medically ranged from 2 to 12 days (average: 6.9 days), while for those who underwent surgery,the range was 1 to 14 days (average 5.4 days). At surgery,adhesions were the only finding in 46 cases, while there were intestinal complications in 27, or 9.2 % of all 293admissions. Fever and leukocytosis greater than 15 000/mm3were prediction of intestinal complications.CONCLUSION: With closely monitoring, most patients with small bowel obstruction due to postoperative adhesions could tolerate supportive treatment and recover well averagely within 1 week, although some patients require more than 10 days of observation.Shou-Chuan Shih Kuo-Shyang Jeng Shee-Chan Lin Chin-Roa Kao Sun-Yen Chou Horng-Yuan Wang Wen-Hsiung Chang Cheng-Hsin Chu Tsang-En Wang 2003World Journal of Gastroenterology2003,9,3:26
18Effect of ginger Effect of ginger on gastric motility and symptoms of functional dyspepsiaon gastric motility and symptoms of functional dyspepsia显示文摘AIM:To evaluate the effects of ginger on gastric motility and emptying,abdominal symptoms,and hormones that influence motility in dyspepsia.METHODS:Eleven patients with functional dyspepsia were studied twice in a randomized double-blind manner.After an 8-h fast,the patients ingested three capsules that contained ginger(total 1.2 g) or placebo,followed after 1 h by 500 mL low-nutrient soup.Antral area,fundus area and diameter,and the frequency of antral contractions were measured using ultrasound at frequent intervals,and the gastric half-emptying time was calculated from the change in antral area.Gastrointestinal sensations and appetite were scored using visual analog questionnaires,and blood was taken for measurement of plasma glucagon-like peptide-1(GLP-1),motilin and ghrelin concentrations,at intervals throughout the study.RESULTS:Gastric emptying was more rapid after ginger than placebo [median(range) half-emptying time 12.3(8.5-17.0) min after ginger,16.1(8.3-22.6) min after placebo,P ≤ 0.05].There was a trend for more antral contractions(P = 0.06),but fundus dimensions and gastrointestinal symptoms did not differ,nor did serum concentrations of GLP-1,motilin and ghrelin.CONCLUSION:Ginger stimulated gastric emptying and antral contractions in patients with functional dyspepsia,but had no impact on gastrointestinal symptoms or gut peptides.Ming-Luen Hu Christophan K Rayner Keng-Liang Wu Seng-Kee Chuah Wei-Chen Tai Yeh-Pin Chou Yi-Chun Chiu King-Wah Chiu Tsung-Hui Hu 2011World Journal of Gastroenterology2011,17,1:19
19Transcatheter arterial embolization treatment in patients with hepatocellular carcinoma and risk of pulmonary metastasis显示文摘AIM: To investigate the relationship between transcatheterarterial embolization (TAE) and pulmonary metastasis insubjects with hepatocellular carcinoma (HCC). METHODS: A total of 287 patients with HCC followed upfor more than 1 week were included. 102 patients underwenttranscatheter arterial embolization (TAE group) and 185received conservative treatment(control group). Thepatients' chest x-rays and chest CT scans were examinedfor pulmonary metastasis.RESULTS: Patients with TAE had a median survival of 19.3months while that of the control group was only 10.0 months(P<0.05). Pulmonary metastasis occurred in 14 (13.7 %)patients in the TAE group and 14 (7.6 %) patients in the control group, there was no significant difference (P>0.05).The 1-year, 2-year and 5-year cumulative incidence of pulmonary metastasis was 11.8 %, 17.6 % and 24.0 % in the TAE group and 7.0 %, 13.0 % and 21.7 % in the control group, respectively (P>0.05). On the univariate analysis,tumor size, abnormal serum alanine aminotransferase levels and heterogeneity on sonography were significantly associated with pulmonary metastasis. However, on the multivariate analysis, only tumor size was significantly predictive of pulmonary metastasis.CONCLUSION: TAE is effective on prolonging survival of patients with HCC. It does not significantly increase the risk of pulmonary metastasis. Tumor size is the only significant predictive factor associated with lung metastasis.Shee-Chan Lin Shou-Chuan Shih Chin-Roa Kao Sun-Yen Chou 2003World Journal of Gastroenterology2003,9,6:18
20Strategy and methodology of dynamical analogue prediction显示文摘In order to effectively improve numerical prediction level by using current models and data, the strategy and methodology of dynamical analogue prediction (DAP) is deeply studied in the present paper. A new idea to predict the prediction errors of dynamical model on the basis of historical analogue information is put forward so as to transform the dynamical prediction problem into the estimation problem of prediction errors. In terms of such an idea, a new prediction method of final analogue correction of errors (FACE) is developed. Furthermore, the FACE is applied to extra-seasonal prediction experiments on an operational atmosphere-ocean coupled general circulation model. Prediction results of summer mean circulation and total precipitation show that the FACE can to some extent reduce prediction errors, recover prediction variances, and improve prediction skills. Besides, sensitive experiments also show that predictions based on the FACE are evidently influenced by the number of analogues, analogue-selected variables and analogy metric.REN HongLi1,2? & CHOU JiFan1 1 College of Atmospheric Sciences, Lanzhou University, Lanzhou 730000, China 2 Laboratory for Climate Studies, National Climate Center, China Meteorological Administration, Beijing 100081, China 2007Science China Earth Sciences2007,50,10:17
