| 1 | Radiation belt electron scattering by whistler-mode chorus in the Jovian magnetosphere: Importance of ambient and wave parameters显示文摘Whistler-mode chorus waves are regarded as an important acceleration mechanism contributing to the formation of relativistic and ultra-relativistic electrons in the Jovian radiation belts. Quantitative determination of the chorus wave driven electron scattering effect in the Jovian magnetosphere requires detailed information of both ambient magnetic field and plasma density and wave spectral property, which however cannot be always readily acquired from observations of existed missions to Jupiter. We therefore perform a comprehensive analysis of the sensitivity of chorus induced electron scattering rates to ambient magnetospheric and wave parameters in the Jovian radiation belts to elaborate to which extent the diffusion coefficients depend on a number of key input parameters. It is found that quasi-linear electron scattering rates by chorus can be strongly affected by the ambient magnetic field intensity, the wave latitudinal coverage, and the peak frequency and bandwidth of the wave spectral distribution in the Jovian magnetosphere, while they only rely slightly on the background plasma density profile and the peak wave normal angle, especially when the wave emissions are confined at lower latitudes. Given the chorus wave amplitude, chorus induced electron scattering rates strongly depend on Jovian L-shell to exhibit a tendency approximately proportional to L_J^3. Our comprehensive analysis explicitly demonstrates the importance of reliable information of both the ambient magnetospheric state and wave distribution property to understanding the dynamic electron evolution in the Jovian radiation belts and therefore has implications for future mission planning to explore the extreme particle radiation environment of Jupiter and its satellites. | BinBin Ni Jing Huang YaSong Ge Jun Cui Yong Wei XuDong Gu Song Fu Zheng Xiang ZhengYu Zhao | 2018 | Earth and Planetary Physics2018，2，1： | 3 |
| 2 | Progress on diagnostic and prognostic markers of pancreatic cancer显示文摘Pancreatic cancer is a malignant disease characterized by low survival and high recurrence rate,whose patients are mostly at the stage of locally advanced or metastatic disease when first diagnosed.Early diagnosis is particularly important because prognostic/predictive markers help guide optimal individualized treatment regimens.So far,CA19-9 is the only biomarker for pancreatic cancer approved by the FDA,but its effectiveness is limited by low sensitivity and specificity.With recent advances in genomics,proteomics,metabolomics,and other analytical and sequencing technologies,the rapid acquisition and screening of biomarkers is now possible.Liquid biopsy also occupies a significant place due to its unique advantages.In this review,we systematically describe and evaluate the available biomarkers that have the greatest potential as vital tools in diagnosing and treating pancreatic cancer. | HONG YANG WAN LI LIWEN REN YIHUI YANG YIZHI ZHANG BINBIN GE SHA LI XIANGJIN ZHENG JINYI LIU SEN ZHANG GUANHUA DU BO TANG HONGQUAN WANG JINHUA WANG | 2023 | Oncology Research2023，31，2： | 1 |
