| 1 | Quantitative analysis of diffusion-weighted magnetic resonance images:differentiation between prostate cancer and normal tissue based on a computer-aided diagnosis system显示文摘Diffusion-weighted imaging(DWI) is considered to be one of the dominant modalities used in prostate cancer(PCa) detection and the assessment of lesion aggressiveness,especially for peripheral zone(PZ) PCa.Computer-aided diagnosis(CAD),which is capable of automatically extracting and evaluating image features,can integrate multiple parameters and improve the detection of PCa.In this study,13 quantitative image features were extracted from DWI by CAD,and diagnostic efficacy was analyzed in both the PZ and transition zone(TZ).The results demonstrated that there was a significant difference(P<0.05) between PCa and non-PCa for nine of the 13 features in the PZ and five of the 13 features in the TZ.Besides,the prediction outcome of CAD had a strong correlation with the DWI scores that were graded by experienced radiologists according to the Prostate Imaging-Reporting and Data System Version 2(PI-RADS v2). | Ge Gao Chengyan Wang Xiaodong Zhang Juan Hu Xuedong Yang He Wang Jue Zhang Xiaoying Wang | 2017 | Science China(Life Sciences)2017，60，1： | 13 |
| 2 | Synergistic effects of CeO_(2)/Cu_(2)O on CO catalytic oxidation:Electronic interaction and oxygen defect显示文摘For CO catalytic oxidation,Cu and Ce species are of great importance,between which the synergistic effect is worth investigating.In this work,CeO_(2)/Cu_(2)O with Cu_(2)O {111} and {100} planes were comparatively explored on CO catalytic oxidation to reveal the effects of interfacial electronic interactions and oxygen defects.The activity result demonstrates that CeO_(2)/o-Cu_(2)O {111} has superior performance compared with CeO_(2)/c-Cu_(2)O {100}.Credit to the coordination unsaturated copper atoms(Cu_(CUS)) on oCu_(2)O {111} surface,the interfacial electronic interactions on CeO_(2)/o-Cu_(2)O {111} are more obvious than those on CeO_(2)/c-Cu_(2)O {100},leading to richer oxygen defect generation,better redox and activation abilities of CO and O_(2) reactants.Furthermore,the reaction mechanism of CeO_(2)/o-Cu_(2)O {111} on CO oxidation is revealed,i.e.,CO and O_(2) are adsorbed on the Cucus on Cu_(2)O {111} and oxygen defect of CeO_(2),respectively,and then synergistically promote the CO oxidation to CO_(2).The work sheds light on the designing optimized ceria and copper-based catalysts and the mechanism of CO oxidation. | Chengyan Ge Jingfang Sun Qing Tong Weixin Zou Lulu Li Lin Dong | 2022 | Journal of Rare Earths2022，40，8： | 1 |
