Firstly, an adaptive synchronization method is presented and explained. Then, it is applied to two different classes of dynamical networks, one is a class-B network, small-world connected R6 ssler oscillators, the other is a class-A network, small-world connected Chua＇s circuits. The simulation verifies the validity of the presented method. It also shows that the adaptive synchronization method is robust to the variations of the node systems parameters. So the presented method can be used in networks whose node systems have unknown or time-varying parameters.展开更多

As well,we analyzed the sedimentary environment and lithologic features of every basin-forming period. The results show that there are several favorable source-reservoir-cap assemblages in our study area,making it a major region for future oil and gas exploration in China’s northern Sichuan basin.展开更多

The era of electricity also put his mark on the Romanian alveolus of civilization. The paper deals with an analysis of the scientific researches and applications which express the results of works of eminent scientists and engineers in electro-techniques and related domains, in Romania, in the first decade of interwar period 1919-1929. The scientific activities developed in many domains of Science are sustained by the significant technical progress in Romania, in this short but relevant period of Tempus in which, in Europe and in other parts of Civitas Terra, was peace.展开更多

Methods： WB-DWI with GE 1.5T MR/I was performed on 10 healthy volunteers and 35 patients. WB-DWl and ECT was performed in all 35 patients. Using WB-DWl for detecting bone metastasis and compared them with that of ECT. Results： Background was suppressed in WB-DWl, fat, muscle, vessels and liver appeared same as background. Skeleton showed medium or slightly lower signal. Lymph nodes, some glandular organs, kidneys displayed medium signal. Spleen, testicle, brain tissue were low signal. Bladder, gallbladder were depicted as low signal because of ＂T2 through＂. Bone metastasis were multitude and inequality of size, punctiform, nodosity, column low intensity. Concordance between WB-DWI and ECT was seen in 4 cases. WB-DWl displayed 1 bone metastasis on skull, 46 on rib and sternum, 3 on scapula, 4 on extremities, 83 on vertebral, 36 on pelvic bone. ECT showed 2 bone metastasis on skull, 62 on rib and sternum, 7 on scapula, 9 on extremities, 64 on vertebral, 19 on pelvic bone. WB-DWl was 74% for bone metastasis on rib and sternum, ECT was 77%, 53% for vertebral and pelvic bone. All of the focus were statistics analyses, P 〈 0.05. Total probability distribution inequality if metastasis on different positions. Conclusion： WB-DWI was an effective imaging technology for screening bone metastasis.展开更多

Methods： Fifty patients, including 29 females and 21 males, with a median age 62 years （35–82 years）, 13 of whom were treated with pemetrexed only and the left 37 cases were treated with pemetrexed combined with platinum in the Department of Oncology, Renmin Hospital of Wuhan University from June 2006 to March 2009. Single agent regimen： patients received pemetrexed 500 mg/m2 on day 1 with every 21 days. Combination regimen： patients received pemetrexed 500 mg/m2 on day 1 and carboplatin 300 mg/m2 on day 1 or cisplatin 35 mg/m2 on day 1 to day 3 or nedaplatin 80 mg/m2 on day 1 by intravenous infusion with 21 days as one cycle. RECIST 1.0 standard was used to evaluate the clinical efficiency, and the WHO toxicity standard was used to evaluate toxic reaction, and the QOL was used to evaluate the quality of life. Results： All patients were given 162 cycles （at least 2 cycles, at most 6 cycles） and the response rate of all the patients were evaluated. There were 2 complete remission （CR）, 7 partial remission （PR）, 22 stable disease （SD） and 19 progressive disease （PD） in the group, the overall response rate was （RR） was 18.0% and disease control rate （DCR） 62.0%. The quality of life improvement rate reaches 58.0%. The major toxic reaction included neutropenia, thrombocytopenia, hypemia, nausea, and vomiting. Most of the severity of these effects was grade I–II and well tolerated. Conclusion： Chemotherapy with pemetrexed or pemetrexed combined with platinum in the treatment of advanced non-small cell lung cancer is effective, safe and well-tolerable, which can improve quality of life of the patient.展开更多
