| 1 | Rebels Lead to the Doctrine of the Mean: A Heterogeneous DeGroot Model显示文摘The DeGroot model is one of the most classical models in the field of opinion dynamics. The standard DeGroot model assumes that agents are homogeneous and update their opinions in the direction of a weighted average of their neighbors'opinions.One natural question is whether a second type of agents could significantly change the main properties of the model.The authors address this question by introducing rebels,who update their opinions toward the opposite of their neighbors' weighted average.The authors find that the existence of rebels remarkably affects the opinion dynamics. Under certain mild conditions,the existence of a few rebels will lead the group opinion to the golden mean,regardless of the initial opinions of the agents and the structure of the learning network.This result is completely different from that of the standard DeGroot model,where the final consensus opinion is determined by both the initial opinions and the learning topology.The study then provides new insights into understanding how heterogeneous individuals in a group reach consensus and why the golden mean is so common in human society. | CAO Zhigang JIAO Fengliang QU Xinglong WANG Wen-Xu YANG Mingmin YANG Xiaoguang ZHANG Boyu | 2018 | Journal of Systems Science & Complexity2018，31，6： | 0 |
| 2 | Treatment and prognosis of iliac fossa soft tissue sarcoma: A single-center study显示文摘Dear Editor,Primary iliac fossa sarcoma(IFS)is a special type of retroperitoneal sarcoma(RPS),accounting for∼15%of all RPS cases[1].The deep location,large size,and invasion to surrounding tissues and organs are the main causes of unresectability of IFS.All these characteristics are associated with an increased risk of positive surgical margin and a decreased feasibility of adjuvant therapy.In patients with multivisceral and/or vascular involvement,a multivisceral en bloc approach[2]with blood vessel replacement may be required to achieve a negative margin and to improve the quality of resection[3].However,whether these surgical procedures improve prognosis in patients with IFS remain undefined.Moreover,whether aggressive procedures lead to acceptable functional impairment requires validation.In addition,previous studies have reported inconsistent results regarding the role of adjuvant radiotherapy in the treatment of RPS[4].To date,the role of radiotherapy in the local control of IFS remains to be determined.Therefore,we analyzed the clinical features,treatment,and outcomes of IFS patients in an attempt to determine the significant prognostic factors and efficient therapeutics in real clinical practice. | Wei Sun Hongqiang Zhang Biqiang Zheng Ruming Zhang Chunmeng Wang Wangjun Yan Bing Wang Xinglong Qu Yong Chen | 2020 | Cancer Communications2020，40，7： | 0 |
| 3 | Influence of N-doping on dielectric properties of carbon-coated copper nanocomposites in the microwave and terahertz ranges显示文摘Carbon-coated Cu nanocomposites (Cu@C NCs) consisting of core-shell nanoparticles and nanorods weresynthesized by arc discharge plasma under an atmosphere of He and H_(2) gas, and the N-doping of themwas achieved by a post-treatment process using ureal as the precursor. The concentration of N in the Ndoped samples varies in the range of 0.62%-2.31 % (in mole), with a transformation from pyrrolic N tographitic N when increasing the relative content of ureal. Dielectric properties of the NCs without or withN-doping in the microwave and THz bands were investigated. The N-doped samples achieve theenhanced dielectric loss in both microwave and THz bands. In the microwave band, dielectric loss wasdominated by interfacial polarization, dipolar polarization, and conduction loss, while in the THz band,plasma resonance, ionic polarization and conduction loss are responsible for the dielectric loss, with astrong absorption characteristic dominated by conductive effect. | Feirong Huang Shuting Fan Yuqi Tian Xinghao Qu Xiyang Li MaoFan Qin Javid Muhammad Xuefeng Zhang Zhidong Zhang Xinglong Dong | 2022 | Journal of Materiomics2022，8，6： | 0 |
| 4 | 同时三原发性消化道肿瘤1例(英文)显示文摘Multiple primary carcinoma which is the same organ of the same patient or multiple organs, tissues has occurred two or more than two kinds of the primary malignant tumor. All cancer at the same time or 6 months from diagnosis is called simultaneous multiple primary carcinoma. In this case the patient suffering from cancer including rectal cancer, colon cancer and appendix gastrointestinal stromal tumor(GIST) three primary carcinoma, is simultaneous multiple primary carcinoma and it's extremely rare on the clinical cases. This report address that the incidence of the patient with operation and pathological diagnosis. | Xinglong Qu Yu Han Yi Zhang Bing Wang | 2014 | The Chinese-German Journal of Clinical Oncology2014，13，9： | 0 |
