1γ-MnO2 nanorods/graphene composite as efficient cathode for advanced rechargeable aqueous zinc-ion battery显示文摘Aqueous Zn//MnO2 batteries are emerging as promising large-scale energy storage devices owing to their cost-effectiveness,high safety,high output voltage,and energy density.However,the MnO2 cathode suffers from intrinsically poor rate performance and rapid capacity deterioration.Here,we remove the roadblock by compositing MnO2 nanorods with highly conductive graphene,which remarkably enhances the electrochemical properties of the MnO2 cathode.Benefiting from the boosted electric conductivity and ion diffusion rate as well as the structural protection of graphene,the Zn//MnO2-graphene battery presents an admirable capacity of 301 mAh g^-1 at 0.5 A g^-1,corresponding to a high energy density of 411.6 Wh kg^-1.Even at a high current density of 10 A g^-1,a decent capacity of 95.8 mAh g^-1 is still obtained,manifesting its excellent rate property.Furthermore,an impressive power density of 15 kW kg^-1 is achieved by the Zn//MnO2-graphene battery.Chao Wang Yinxiang Zeng Xiang Xiao Shijia Wu Guobin Zhong Kaiqi Xu Zengfu Wei Wei Su Xihong Lu 2020Journal of Energy Chemistry2020,29,4:13
2Radiotherapy combined with immunotherapy:the dawn of cancer treatment显示文摘Radiotherapy(RT)is delivered for purposes of local control,but can also exert systemic effect on remote and non-irradiated tumor deposits,which is called abscopal effect.The view of RT as a simple local treatment has dramatically changed in recent years,and it is now widely accepted that RT can provoke a systemic immune response which gives a strong rationale for the combination of RT and immunotherapy(iRT).Nevertheless,several points remain to be addressed such as the interaction of RT and immune system,the identification of the best schedules for combination with immunotherapy(IO),the expansion of abscopal effect and the mechanism to amplify iRT.To answer these crucial questions,we roundly summarize underlying rationale showing the whole immune landscape in RT and clinical trials to attempt to identify the best schedules of iRT.In consideration of the rarity of abscopal effect,we propose that the occurrence of abscopal effect induced by radiation can be promoted to 100%in view of molecular and genetic level.Furthermore,the“radscopal effect”which refers to using low-dose radiation to reprogram the tumor microenvironment may amplify the occurrence of abscopal effect and overcome the resistance of iRT.Taken together,RT could be regarded as a trigger of systemic antitumor immune response,and with the help of IO can be used as a radical and systemic treatment and be added into current standard regimen of patients with metastatic cancer.Zengfu Zhang Xu Liu Dawei Chen Jinming Yu 2022Signal Transduction and Targeted Therapy2022,7,8:3
3p53-dependent upregulation of PIG3 transcription by γ-ray irradiation and its interaction with KAP1 in responding to DNA damage显示文摘PIG3 (p53-inducible gene 3), originally identified as one of a set of genes induced by p53 before the onset of apoptosis, was assumed to contribute to early cellular response to DNA damage. Here, we studied the relation between p53 status and the increased expression of PIG3 by ionizing radiation (IR), and the related clues regarding the involvement of PIG3 in the cellular response to IR-induced DNA damage signaling. We demonstrated that the pentanucleotide microsatellite sequence was responsible for the p53-dependent induction of PIG3 transcription after irradiation, while sequence upstream of PIG3 promoter could maintain the basal level of expression which was not inducible by irradiation. The interaction of PIG3 and the KRAB-ZFP-associated protein 1 (KAP1), a DNA damage response protein, was revealed. PIG3 nucleus foci were formed 15 min after γ-ray irradiation, and which were found to partially colocalize with the phospho-KAP-1 foci as well as γ-H2AX foci. Although the lac operator tagged EGFP based reporter system revealed that PIG3 does not remodel chromatin in large scale in the cells under normal growing condition, it indeed prompted the chromatin relaxation in the cellular response to DNA damage signaling. All these data suggest that PIG3 is involved in IR-induced DNA damage response, and which maybe partially attribute to its interaction with KAP1.QIN Xia ZHANG ShiMeng LI Bingi LIU XiaoDan HE XingPeng SHANG ZengFu XU QinZhi ZHAO ZengQiang YE QiNong ZHOU PingKun 2011Chinese Science Bulletin2011,56,30:2

9A SUBARRAY-SYNTHESIS BASED 2D DOA ESTIMATION METHOD显示文摘In some satellite communications, we need to perform Direction Of Arrival (DOA) angle estima- tion under the restriction that the number of receivers is less than that of the array elements in an array antenna. To solve the conundrum, a method named subarray-synthesis-based Two-Dimensional DOA (2D DOA) angle estimation is proposed. In the method, firstly, the array antenna is divided into a series of subarray antennas based on the total number of receivers; secondly, the subarray antennas’ output covariance matrices are esti- mated; thirdly, an equivalent covariance matrix is synthesized based on the subarray output covariance matri- ces; then 2D DOA estimation is performed. Monte Carlo simulations showed that the estimation method is ef- fective.Xu Wenlong Jiang Wei Li Zengfu Shang Yong Xiang Haige 2006Journal of Electronics(China)2006,23,5:0
10Three-dimensional critical slip surface locating and slope stability assessment for lava lobe of Unzen volcano显示文摘Even Unzen volcano has been declared to be in a state of relative dormancy,the latest formed lava lobe No.11 now represents a potential slope failure mass based on the latest research.This paper concentrates on the stability of the lava lobe No.11 and its possible critical sliding mass.It proposes geographic information systems (GIS) based three-dimensional (3D) slope stability analysis models.It uses a 3D locating approach to identify the 3D critical slip surface and to analyze the 3D stability of the lava lobe No.11.At the same time,the new 3D approach shows the effectiveness in selecting the range of the Monte Carlo random variables and locating the critical slip surface in different parts of the lava lobe No.11.The results are very valuable for judging the stability of the lava lobe and assigning the monitoring equipments.Mowen Xie,Zengfu Wang,Xiangyu Liu,Bo Xu School of Civil and Environmental Engineering,University of Science and Technology Beijing,Beijing,100083,China 2011Journal of Rock Mechanics and Geotechnical Engineering2011,3,1:0
