| 1 | Causal propagation of signals in strangeon matter显示文摘The state equation for strangeon matter is very stiff due to the non-relativistic nature of its particles and their repulsive interaction,such that pulsar masses as high as~3 M_⊙ would be expected. However, an adiabatic sound speed, c_s=(?P/?ρ)~(1/2), is usually superluminal in strangeon matter, and the dynamic response of a strangeon star(e.g., binary merger) is not tractable in numerical simulations. In this study, we examined signal propagation in strangeon matter and calculate the actual propagation speed, c_(signal).We found that the causality condition, c_(signal)< c, is satisfied and the signal speed is presented as a function of stellar radius. | JiGuang Lu EnPing Zhou XiaoYu Lai RenXin Xu | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，8： | 1 |

| 3 | Scientific objectives of the Hot Universe Baryon Surveyor(HUBS) mission显示文摘The Hot Universe Baryon Surveyor(HUBS) is a proposed space-based X-ray telescope for detecting X-ray emissions from the hot gas content in our universe. With its unprecedented spatially-resolved high-resolution spectroscopy and large field of view,the HUBS mission will be uniquely qualified to measure the physical and chemical properties of the hot gas in the interstellar medium, the circumgalactic medium, the intergalactic medium, and the intracluster medium. These measurements will be valuable for two key scientific goals of HUBS, namely to unravel the AGN and stellar feedback physics that governs the formation and evolution of galaxies, and to probe the baryon budget and multi-phase states from galactic to cosmological scales. In addition to these two goals, the HUBS mission will also help us solve some problems in the fields of galaxy clusters, AGNs, difuse X-ray backgrounds, supernova remnants, and compact objects. This paper discusses the perspective of advancing these fields using the HUBS telescope. | Joel Bregman Renyue Cen Yang Chen Wei Cui Taotao Fang Fulai Guo Edmund Hodges-Kluck Rui Huang Luis C.Ho Li Ji Suoqing Ji Xi Kang Xiaoyu Lai Hui Li Jiangtao Li Miao Li Xiangdong Li Yuan Li Zhaosheng Li Guiyun Liang Helei Liu Wenhao Liu Fangjun Lu Junjie Mao Gabriele Ponti Zhijie Qu Chenxi Shan Lijing Shao Fangzheng Shi Xinwen Shu Lei Sun Mouyuan Sun Hao Tong Junfeng Wang Junxian Wang Q.Daniel Wang Song Wang Tinggui Wang Weiyang Wang Zhongxiang Wang Dandan Xu Haiguang Xu Heng Xu Renxin Xu Xiaojie Xu Yongquan Xue Hang Yang Feng Yuan Shuinai Zhang Yuning Zhang Zhongli Zhang Yuanyuan Zhao Enping Zhou Ping Zhou | 2023 | Science China(Physics,Mechanics & Astronomy)2023，66，9： | 1 |
| 4 | The Significance of PSA Modified Parameters (F/T)/PSAD for Diagnosing Prostatic Cancer in the Grey Zone of 4~10 ng/ml显示文摘OBJECTIVE To investigate the diagnostic value of modified prostate specific antigen(PSA)parameters in the diagnosis of prostate cancer(PCA) when the serum PSAis in a grey zone of 4~10 ng/ml. METHODS The results of serum PSA determinations of the patients receiving a transrectal ultrasound-guided multiphase prostatic biopsy,were retrospectively analyzed.In the 88 patients with a serum PSA value of 4-10 ng/ml,the final diagnosis of PCA was made in 21,and that of benign prostate hyperplasia(BPH)in 67 patients.The percentage of the free-serum PSA([FPSA]/total-serum PSA[TPSA],F/T),PSA density(PSAD)and the sensitivity and specificity of the new PSA modified parameter(F/T)/PSAD in diagnosing PCA,within a set threshold value,was compared. RESULTS In the 88 patients with serum PSA in the grey zone of 4.0-10.0 ng/ml,there was no significant difference in comparing the TPSA between the 21 PCA patients and 67 BPH patients(P>0.05).However, there was a significant difference in the value of modified PSA parameters, such as F/T,PSAD and(F/T)/PSAD,between the PCA and the BPH groups (P<0.001).As the cut off point-value of the F/T,PSAD and(F/T)/PSAD was set at 0.16,0.15 and 0.8,the diagnostic sensitivity for PCA was 66.7%, 76.2%and 85.7%,and the specificity was 41.8%,43.3%and 68.7%,respectively.There was no significant difference in the sensitivity comparing the modified parameters for diagnosing PCA(P>0.05),whereas an overt predominance was present in the specificity of(F/T)/PSAD for PCAdiagnosis (P<0.05). CONCLUSION In the serum PSA grey zone of 4-10 ng/ml,a modified PSA parameter can improve the PCA diagnostic accuracy rate.With a considerably high sensitivity,application of the(F/T)/PSAD may effectively enhance the diagnostic specificity,which is superior to the F/T and PSAD, and can be expected to be one of the new indices derived from the PSA. | Dongliang Yan Enping Hu Haitao Zhang Sheng Liu Hairong Cai Lei Zhang Yan Zhou | 2007 | Chinese Journal of Clinical Oncology2007，4，5： | 1 |
| 5 | GLTSCR1 coordinates alternative splicing and transcription elongation of ZO1 to regulate colorectal cancer progression显示文摘Alternative splicing(AS)and transcription elongation are vital biological processes,and their dysregulation causes multiple diseases,including tumors.However,the coregulatory mechanism of AS and transcription elongation in tumors remains unclear.This study demonstrates a novel AS pattern of tight junction protein 1(ZO1)regulated by the RNA polymerase II elongation rate in colorectal cancer(CRC).Glioma tumor suppressor candidate region gene 1(GLTSCR1)decreases the transcription elongation rate of ZO1 to provide a time window for binding of the splicing factor HuR to the specific motif in intron 22 of ZO1 and spliceosome recognition of the weak 3 and 5 splice sites in exon 23 to promote exon 23 inclusion.Since exon 23 inclusion in ZO1 suppresses migration and invasion of CRC cells,our findings suggest a novel potential therapeutic target for CRC. | Fengyan Han Beibei Yang Mingyue Zhou Qiong Huang Minglang Mai Zhaohui Huang Maode Lai Enping Xu Honghe Zhang | 2022 | Journal of Molecular Cell Biology2022，14，2： | 1 |
| 6 | Free Energy of Anisotropic Strangeon Stars显示文摘Can pulsar-like compact objects release further huge free energy besides the kinematic energy of rotation?This is actually relevant to the equation of state of cold supra-nuclear matter,which is still under hot debate.Enormous energy is surely needed to understand various observations,such asγ-ray bursts,fast radio bursts and softγ-ray repeaters.In this paper,the elastic/gravitational free energy of solid strangeon stars is revisited for strangeon stars,with two anisotropic models to calculate in general relativity.It is found that huge free energy(>10^(46)erg)could be released via starquakes,given an extremely small anisotropy((p_(t)-p_(r))/p_(r)~10^(-4),with pt/pr the tangential/radial pressure),implying that pulsar-like stars could have great potential of free energy release without extremely strong magnetic fields in the solid strangeon star model. | Shichuan Chen Yong Gao Enping Zhou Renxin Xu | 2024 | Research in Astronomy and Astrophysics2024，24，2： | 0 |
| 7 | The Precursor of GRB211211A:A Tide-induced Giant Quake?显示文摘The equilibrium configuration of a solid strange star in the final inspiral phase with another compact object is generally discussed,and the starquake-related issue is revisited,for a special purpose to understand the precursor emission of binary compact star merger events(e.g.,that of GRB211211A).As the binary system inspirals inward due to gravitational wave radiation,the ellipticity of the solid strangeon star increases due to the growing tidal field of its compact companion.Elastic energy is hence accumulated during the inspiral stage which might trigger a starquake before the merger when the energy exceeds a critical value.The energy released during such starquakes is calculated and compared to the precursor observation of GRB211211 A.The result shows that the energy might be insufficient for binary strangeon-star case unless the entire solid strangeon star shatters,and hence favors a black hole-strangeon star scenario for GRB211211A.The timescale of the precursor as well as the frequency of the observed quasi-periodic-oscillation have also been discussed in the starquake model. | Enping Zhou Yong Gao Yurui Zhou Xiaoyu Lai Lijing Shao Weiyang Wang Shaolin Xiong Renxin Xu Shuxu Yi Garvin Yim Han Yue Zhen Zhang | 2024 | Research in Astronomy and Astrophysics2024，24，2： | 0 |
