| 1 | Mobile-Edge Computing Framework with Data Compression for Wireless Network in Energy Internet显示文摘Under the situations of energy dilemma, energy Internet has become one of the most important technologies in international academic and industrial areas. However, massive small data from users, which are too scattered and unsuitable for compression, can easily exhaust computational resources and lower random access possibility, thereby reducing system performance. Moreover, electric substations are sensitive to transmission latency of user data, such as controlling information. However, the traditional energy Internet usually could not meet requirements. Integrating mobile-edge computing makes energy Internet convenient for data acquisition,processing, management, and accessing. In this paper, we propose a novel framework for energy Internet to improve random access possibility and reduce transmission latency. This framework utilizes the local area network to collect data from users and makes conducting data compression for energy Internet possible. Simulation results show that this architecture can enhance random access possibility by a large margin and reduce transmission latency without extra energy consumption overhead. | Luning Liu Xin Chen Zhaoming Lu Luhan Wang Xiangming Wen | 2019 | Tsinghua Science and Technology2019，24，3： | 7 |

| 3 | Angular distribution of terahertz emission from laser interactions with solid targets显示文摘Intense femtosecond laser-plasma interactions can produce high power terahertz radiations.In our experiment,the polished copper target was irradiated by a p-polarized laser with intensity of more than 1018 W/cm2 at an incident angle of 67.5 from the target normal.The THz energy from three dierent detection angles is measured.The maximum emission is found in the direction at an angle of 45 to the laser backward direction,which is more than one order of magnitude higher than in the other two directions.A simple theoretical model has been established to explain the measurements. | DU Fei LI Chun ZHOU MuLin WANG WeiMin SU LuNing ZHENG Yi GE XuLei LI YuTong MA JingLong LIU XiaoLong ZHANG Lu SHENG ZhengMing CHEN LiMing LU Xin DONG QuanLi WANG ZhaoHua WEI ZhiYi ZHANG Jie | 2012 | Science China(Information Sciences)2012，55，1： | 2 |
| 4 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |
| 5 | Expression and regulation of genes involved in the reserve starch biosynthesis pathway in hexaploid wheat (Triticum aestivum L.)显示文摘Reserve starch of cereal crop accounts for about 70%of grain endosperm and acts as an important human carbohydrate resource worldwide.Wheat reserve starch is synthesized by enzymatic machinery in endosperm cells.To identify genes involved in starch biosynthesis,we constructed 30 RNA-Seq libraries of 10 endosperm-development periods and performed expression and localization analyses.Of 166 endosperm-expressed homologs of starch biosynthesis-related genes,74 showed expression correlated with reserve starch accumulation,including 26 with expected subcellular distribution and higher expression than their isoforms.The key proteins SUS3,UGP1,cAGPase,and Bt1-3 formed the main metabolic pathway and contributed the major substrates for starch processing in amyloplasts.Important isoforms,key pathway proteins,and the main carbon flux toward starch formation in the reserve starch biosynthesis pathway were identified.Based on a coexpression analysis,a library of 425 transcription factors was produced to screen for common regulators.TaMYB44 had features of transcription factors and bound to TaSUT1,TaSSIIIa,TaBEIIa,TaISA1,and TaBEIIb promoters in yeast,suggesting that the gene is a pathway regulator.This study sheds light on understanding the mechanism of reserve starch biosynthesis and will be helpful for increasing starch content in wheat endosperm via biotechnological strategies. | Yunsong Gu Shichen Han Lin Chen Junyi Mu Luning Duan Yaxuan Li Yueming Yan Xiaohui Li | 2021 | The Crop Journal2021，9，2： | 1 |
| 6 | The influence of target material and thickness on proton energy and angular distribution显示文摘The paper has studied the influence of target material and thickness on energy and angular distributions of the protons generated by using an 800 nm,60 fs,0.24 J laser pulse to irradiate solid target foils.The results show that the initial density and thickness of the targets will affect the formation of the acceleration sheath fields in the target normal direction.For the same target thickness,using lower density target materials can obtain a higher proton maximum energy.However,lower density targets tend to be deformed due to the shock waves launched by the laser pulses,making the proton spatial distribution more divergent. | SU LuNing LIU BiCheng LIN XiaoXuan LIU Feng DU Fei LIU XiaoLong ZHENG Yi GE XuLei LI YuTong SHENG ZhengMing CHEN LiMing WANG WeiMin MA JingLong LU Xin WEI ZhiYi CHEN JiaEr ZHANG Jie | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，2： | 1 |

| 8 | Shen-Qi-Wan Protects the Renal Peritubular Capillary Injury from Adenine-mediated Damage by Upregulating Aquaporin 1显示文摘Background:Shen-Qi-Wan(SQW),a commonly used prescription against chronic kidney disease(CKD)in Tradi-tional Chinese Medicine(TCM),has a nephroprotective action in adenine-induced kidney injury.However,the mechanism of SQW in renal injury remains unclear.Objective:This study was undertaken to measure the effect of SQW on peritubular capillary injury both in vivo and in vitro assays.Methods:The effect of SQW on the peritubular capillary injury was evaluated according to measuring hypothalamic-pituitary-adrenal(HPA)function,inflammatory cytokines,VEGF(vascular endothelial growth fac-tor),CD34(Cluster of differentiation 34),and AQP1(Aquaporin 1)levels in the kidney,cell migration,and lumen forming capacity.Results:SQW supplementation could ameliorate dysfunction of the HPA and renal function loss induced by adenine.SQW also significantly inhibited the inflammatory cytokines including MCP-1(monocyte chemotactic protein-1)and VCAM-1(vascular cell adhesion molecule-1)level.Alternatively,SQW administration showed an ameliorating effect from the toxicity and alleviated the injury of capillaries around renal tubules instigated by adenine through increasing AQP1 mRNA and protein level.SQW medicated the serum enhanced the migration and lumen formation ability of HMEC-1 cells,and significantly increased AQP1 protein level.Moreover,AQP1 knockdown efficiently inhibited the migration and lumen formation ability in HMEC-1 cells,and weakened the effect of SQW medicated serum.Conclusion:These results suggested that SQW attenuated peritubular capillary injury in adenine-induced CKD model rats through boosting angiogenesis in endothelial cell,and AQP1 may be a potential target of SQW for treating the renal injury. | Yuting Bao Yehui Zhang Yuanxiao Yang Xueming Chen Luning Lin Yunbo Fu Liting Ji Changyu Li | 2022 | Clinical Complementary Medicine and Pharmacology2022，2，1： | 1 |
| 9 | Polarization of terahertz emission out of incident plane from laser interactions with solid targets显示文摘A powerful terahertz(THz) pulse was produced by a p-polarized,70 fs,800 nm laser interacting with solid targets at an incident angle of 45°.The polarization of the THz emission was measured out of the laser incident plane.The results showed that it was linearly polarized.We established a surface current model to explain this phenomenon,assuming that the transient current moving along the plasma surface was responsible for the generation of the THz emission.The model expectation and the experimental result were in good agreement. | DU Fei LI Chun ZHOU MuLin WANG WeiMin SU LuNing ZHENG Yi LI YuTong MA JingLong SHENG ZhengMing CHEN LiMing LU Xin WANG ZhaoHua WEI ZhiYi ZHANG Jie | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，4： | 1 |
| 10 | Associations of particulate matter with dementia and mild cognitive impairment in China: A multicenter cross-sectional study显示文摘Ambient air pollution has been shown to be associated with the pathogenesis of dementia and mild cognitive impairment(MCI).However,few studies have examined these associations in well-characterized populations with low residential mobility,similar living habits,and a standardized assessment of both air pollution exposure and clinical outcome.This study examined the associations of long-term exposure to particulate matter(PM)air pollution with dementia and MCI,using data from the Chinese Veteran Clinical Research Platform.The cognitive function of elderly veterans from 277 communities in 18 Chinese cities was examined.Participants’daily exposures to aerodynamic diameters%2.5 mm(PM2.5)and%10 mm(PM10)during the 3 years prior to the survey were estimated using a satellite-based prediction.The adjusted odds ratios(ORs)and 95%confidence intervals of MCI associated with each 10 mg/m^(3) increase in PM2.5 and PM10 were 1.52(1.39,1.67)and 1.04(1.00,1.08),and those of dementia associated with PM2.5 and PM10 were 1.27(1.11,1.46)and 1.13(1.05,1.21),respectively.This demonstrates that long-term exposure to PM2.5 and PM10 can increase the prevalence of dementia/MCI among veterans in China.Higher ORs were observed for those with%9 years of educational attainment,those who actively attended physical activities,those who never smoked,former drinkers,and those who did not suffer from cerebral infarction.Improvement of ambient air quality,especially decreasing levels of PM2.5,may help to decrease the risk of dementia/MCI.Given the statistically significant association between PM and cognitive impairment demonstrated here,future studies should focus on examining the causal effect of PM pollution on dementia and MCI. | Jiping Tan Nan Li Xiaoxiao Wang Gongbo Chen Lailai Yan Luning Wang Yiming Zhao Shanshan Li Yuming Guo | 2021 | The Innovation2021，2，3： | 1 |
| 11 | Proton angular distribution research by a new angle-resolved proton energy spectrometer显示文摘The proton spectral and angular distributions simultaneously within the target normal direction and laser propagation direction by using an angle-resolved proton energy spectrometer are studied.For the protons generated in the interactions of 100 fs,800nm laser pulses with aluminum foil targets,the deviations of proton beam centers of different energies from the target normal direction towards the laser propagation direction are different.This is probably because of the toroidal magnetic fields generated at the rear target surface,which deflect protons transversely.As a result,protons in low energy range have large deviation angles,protons in middle energy range have the smallest deviation angles,while protons in high energy tail have large deviation angles. | SU LuNing ZHENG Yi LIU Meng HU ZhiDan WANG WeiMin YUAN XiaoHui XU MiaoHua SHENG ZhengMing SHEN ZhongWei FAN HaiTao LI YuTong MA JingLong LU Xin CHEN LiMing WANG ZhaoHua WEI ZhiYi ZHANG Jie | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，5： | 1 |
| 12 | Increased expression of osteoprotegerin in vascular smooth muscle cells from spontaneously hypertensive rats显示文摘Background Osteoprotegerin (OPG) is a secreted protein of the tumor necrosis factor receptor family, which regulates bone mass by inhibiting osteoclast differentiation and activation. Although OPG is expressed ubiquitously and abundantly in many tissues and cell types including vascular cells, the role of OPG in other tissues is unknown.Our previous studies demonstrated that OPG was highly expressed in vascular smooth muscle cells (VSMC) and upregulated during vascular lesion formation. Methods and Results We documented, by Northern blot analysis,that the expression of OPG was more prevalent in the aorta and cultured VSMC from spontaneously hypertensive rats (SI-IR) compared to Wistar-Kyoto rats (WKY). In addition, we found that the expression of Angiotensin II (Ang II)type I receptor (AT1R) in SHR VSMC was at significantly increased levels than in WKY VSMC. Furthermore, Ang II potently induced the expression of OPG in VSMC in a time- and dose-dependent manner through the AT1R signaling pathway. Conclusions OPG expression was substantially greater in SHR VSMC, suggesting that OPG may be an important determinant of vascular remodeling in SHR. | Yongshan MOU Tianhua LEI Luning ZHAO Xiaojun ZHU Mingui FU Yuqing E CHEN | 2004 | Journal of Geriatric Cardiology2004，1，1： | 0 |

| 14 | N-doped carbon shell encapsulated PtZn intermetallic nanopartides as highly efficient catalysts for fuel cells显示文摘The high cost and poor durability of Pt nanoparticles(NPs)have always been great challenges to the commercialization of proton exchange membrane fuel cells(PEMFCs).Pt-based intermetallic NPs with a highly ordered structure are considered as promising catalysts for PEMFCs due to their high catalytic activity and stability.Here,we reported a facile method to synthesize N-doped carbon encapsulated PtZn intermetallic(PtZn@NC)NPs via the pyrolysis of Pt@Zn-based zeolitic imidazolate framework-8(Pt@ZIF-8)composites.The catalyst obtained at 800℃(10%-PtZn@NC-800)was found to exhibit a half-wave potential(Ev2)up to 0.912 V versus reversible hydrogen electrode(RHE)for the cathodic oxygen reduction reaction in an acidic medium,which shifted by 26 mV positively compared to the benchmark Pt/C catalyst.Besides,the mass activity and specific activity of 10%-PtZn@NC-800 at 0.9 V versus RHE were nearly 3 and 5 times as great as that of commercial Pt/C,respectively.It is worth noting that the PtZn@NC showed excel Ient stability in oxygen reducti on reacti on(ORR)with just 1 mV of the Ev2 loss after 5,000 cycles,which is superior to that of most reported PtM catalysts(especially those disordered solid solutions).Furthermore,such N-doped carb on shell encapsulated PtZn intermetallic NPs showed significa ntly enha need performances towards the anodic oxidation reaction of organic small molecules(such as methanol and formic acid).The synergistic effects of the N doped carbon encapsulation structure and intermetallic NPs are responsible for outstanding performances of the catalysts.This work provides us a new engineering strategy to acquire highly active and stable multifunctional catalysts for PEMFCs. | Yakun Xue Huiqi Li Xieweiyi Ye Shuangli Yang Zhiping Zheng Xiao Han Xibo Zhang Luning Chen Zhaoxiong Xie Qin Kuang Lansun Zheng | 2019 | Nano Research2019，12，10： | 0 |
| 15 | Safety Analysis and Optimization on Ship⁃Borne Vehicle Mooring显示文摘Aiming at the mooring stability of the ship⁃borne vehicles and the safety of steel chain links under high sea condition,the rigid⁃flexible coupling dynamics model of deck⁃vehicle⁃mooring chain was established,the load characteristics of the mooring chain under class⁃9 sea state were obtained.The failure mode of the chain link and the influence law of the torsion angle on the stress distribution was obtained.Based on Miner's linear cumulative damage theory,the fatigue life of the mooring chain link was analyzed using the corrected mooring link S-N curve.The existing safety hazards were pointed out.The optimization of the mooring scheme was proposed.The conclusions are as follows:1)The mooring scheme can meet the mooring stability requirements of vehicles under high sea condition.2)The failure mode on the outside of the link crown was mainly tensile failure,and the failure mode on the inside is mainly contact fatigue failure under compression.3)The torsion angle had a significant effect on the stress situation of the chain link.When it exceeds 15 degrees,it will no longer meet the strength requirements.4)Through the optimization of the mooring scheme,the fatigue life of the steel chain link has been significantly increased. | Luning Cui Si Chen Yaping Wang Lei Zhang Peng Gao | 2022 | Journal of Harbin Institute of Technology(New Series)2022，29，4： | 0 |
