| 1 | Evening exercise is associated with lower odds of visual field progression in Chinese patients with primary open angle glaucoma显示文摘Background:Exercise is widely known to lower intraocular pressure and increase ocular blood flow,which may be beneficial for glaucoma management.However,there are few studies that have reported on the relationship between exercise and glaucoma progression.The aim of our study was to investigate the exercise habits of those with primary open angle glaucoma(POAG)and its association with the progression of visual field(VF)loss.Methods:Daily physical activity(PA)was monitored by an accelerometer(ActiGraph wGT3x-BT)which patients wore for more than 10 h of being awake on their right wrists for 1 week.Results:Seventy-one non-progressive and 27 progressive patients were enrolled in the study.24-h moderate to vigorous physical activity(MVPA)exercise showed that POAG patients had similar variation trends consisting of 3 wave peaks and 2 wave hollows.Minutes spent in MVPA was 19.89±15.81 and 21.62±15.10 during 07:00–09:00 h(p=0.204),15.40±14.49 and 15.67±12.43 during 15:00–17:00 h(p=0.822)and 17.26±21.11 and 11.42±11.58 during 18:00–20:00 h(p=0.001)in the non-progressive and progressive group,respectively.Univariate analysis indicated that 10 min of MVPA(18:00–20:00 h)[odds ratio,OR(95%CI)=0.82(0.73,0.92)],average mean arterial pressure[OR(95%CI)=0.96(0.94,0.98)],age[OR(95%CI)=1.06(1.03,1.08)],male[OR(95%CI)=0.67(0.48,0.96)],spherical equivalent[OR(95%CI)=1.14(1.07,1.22)]and IOP-lowering medications[OR(95%CI)=1.54(1.16,2.05)]were significantly correlated with having progressive VF damage.Multivariable analysis showed that 10 min of MVPA(18:00–20:00 h)[OR(95%CI)=0.85(0.75,0.97)]was associated with progressive VF loss even after adjusting for other risk factors.Conclusions:Evening exercise may lower the odds of VF progression,suggesting that exercise habits possibly play an important role in glaucoma progression. | Xiafei Pan Kai Xu Xin Wang Guofu Chen Huanhuan Cheng Alice Jia Liu Laurence Tang Hou Lin Zhong Jie Chen Yuanbo Liang | 2020 | Eye and Vision2020，7，1： | 2 |
| 2 | UV light absorbers executing synergistic effects of passivating defects and improving photostability for efficient perovskite photovoltaics显示文摘Metal halide perovskite-based solar cells(PSCs) have rapidly-increased power conversion efficiency(PCE)exceeding 25% but poor stability especially under ultraviolet(UV) light. Meanwhile, non-radiative recombination caused by diverse defects in perovskite absorbers and related interfaces is one of the major factors confining further development of PSCs. In this study, we systematically investigate the role of 2-(2-hydroxy-5-methylphenyl)benzotriazole(UVP) additive in perovskite layers. By adjusting the amount of doped UVP, the quality of perovskite absorbers is significantly improved with enlarged grains, longer lifetime and diffusion length of charge carriers. Furthermore, UVP not only reduces defects for less nonradiative recombination, but also matches energy level alignment for efficient interfacial charge extraction. X-ray photoelectron spectroscopy confirms that N-donor of UVP molecule coordinates with undercoordinated Pb^(2+) on the surface. Interestingly, UVP incorporated in PbI_(2) protects the perovskite by absorbing UV through the opening and closing of the chelating ring. Eventually, the UVP treated PSCs obtain a champion PCE of 22.46% with remarkably enhanced UV stability, retaining over 90% of initial PCE after 60 m W/cm^(2) strong UV irradiation for 9 h while the control maintaining only 74%. These results demonstrate a promising strategy fabricating passivated and UV-resistant perovskite materials simultaneously for efficient and stable perovskite photovoltaics. | Jiale Li Wenjing Qi Yameng Li Sumin Jiao Hao Ling Peng Wang Xin Zhou Khumal Sohail Guangcai Wang Guofu Hou Jingshan Luo Ying Zhao Liming Ding Yuelong Li Xiaodan Zhang | 2022 | Journal of Energy Chemistry2022，31，4： | 1 |

| 6 | Performance improvement of n-i-p μc-Si:H solar cells by gradient hydrogen dilution technique显示文摘High pressure radio frequency plasma enhanced chemical vapor deposition(RF-PECVD)process was adopted to investigate the effect of constant hydrogen dilution technique and gradient hydrogen dilu-tion technique on the structural evolution of intrinsic films and the performance of n-i-p microcrystal-line silicon solar cells.The experiment results demonstrated that the grain size and crystalline volume fraction along the growth direction of intrinsic films can be controlled and the performance of solar cells can be greatly improved by gradient hydrogen dilution technique.An initial active-area efficiency of 5.7%(Voc=0.47V,Jsc=20.2mA/cm2,FF=60%)for the μc-Si:H single-junction n-i-p solar cells and an initial active-area efficiency of 10.12%(Voc=1.2V,Jsc=12.05mA/cm2,FF=70%)for the a-Si:H/μc-Si:H tandem n-i-p solar cells has been achieved. | YUAN YuJie HOU GuoFu ZHANG JianJun XUE JunMing CAO LiRan ZHAO Ying GENG XinHua | 2009 | Science China(Technological Sciences)2009，52，6： | 1 |
| 7 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 8 | Expression pattern and prognostic value of key regulators for N7-methylguanosine RNA modification in prostate cancer显示文摘Alterations in the regulators of RNA methylation modifications,such as N7-methylguanosine(m7G),have been implicated in a variety of diseases.Therefore,the analysis and identification of disease-related m7G modification regulators will accelerate advances in understanding disease pathogenesis.However,the implications of alterations in the regulators of m7G modifications remain poorly understood in prostate adenocarcinoma.In the present study,we analyze the expression patterns of 29 m7G RNA modification regulators in prostate adenocarcinoma using The Cancer Genome Atlas(TCGA)and perform consistent clustering analysis of differentially expressed genes(DEGs).We find that 18 m7G-related genes are differentially expressed in tumor and normal tissues.In different cluster subgroups,DEGs are mainly enriched in tumorigenesis and tumor development.Furthermore,immune analyses demonstrate that patients in cluster 1 have significantly higher scores for stromal and immune cells,such as B cells,T cells,and macrophages.Then,a TCGA-related risk model is developed and successfully validated using a Gene Expression Omnibus external dataset.Two genes(EIF4A1 and NCBP2)are determined to be prognostically significant.Most importantly,we construct tissue microarrays from 26 tumor specimens and 20 normal specimens,and further confirm that EIF4A1 and NCBP2 are associated with tumor progression and Gleason score.Therefore,we conclude that the m7G RNA methylation regulators may be involved in the poor prognosis of patients with prostate adenocarcinoma.The results of this study may provide support for exploring the underlying molecular mechanisms of m7G regulators,especially EIF4A1 and NCBP2. | Qiliang Zhai Yan Hou Yuedian Ye Sujuan Dai Guangxiu Guo Qiao Yang Guofu Pang Qiang Wei | 2023 | Acta Biochimica et Biophysica Sinica2023，55，4： | 0 |
| 9 | Recent progress on efficient perovskite/organic tandem solar cells显示文摘The concept of tandem solar cells(TSCs) is an effective way to substantially further improve the efficiency of solar cells. The excellent optoelectronic properties and bandgap tunability of perovskites make them promising for constructing efficient TSCs. Currently, TSCs based on perovskite have been extensively studied. Besides, the performance of organic solar cells has been greatly improved recently due to the wider and more efficient spectral utilization. Accordingly, research on perovskite/organic TSCs has garnered significant attention. It has potential application advantages in emerging fields such as wearable devices by virtue of flexibility. In addition, orthogonal solvents can be adopted to realize the separate preparation of subcells with the solution method, which greatly reduces fabrication complexity;moreover, fabrication with less equipment significantly cuts down the device cost. Meanwhile, organics with more adjustability on the optoelectronic properties provide more tuning strategies for high-performance perovskite/organic TSCs. However, comprehensive and timely reviews on the perovskite/organic TSCs are deficient. Therefore, we expect to accomplish a review on this innovative TSCs to facilitate researchers with a deeper understanding of perovskite/organic TSCs. Herein, we firstly review the significant progress of perovskite and organic solar cells. Then, current achievements of perovskite/organic TSCs are summarized and introduced with a particular focus on the device structure design. Finally, we discuss existential challenges and propose effective strategies for future engineering. | Rongbo Wang Meidouxue Han Ya Wang Juntao Zhao Jiawei Zhang Yi Ding Ying Zhao Xiaodan Zhang Guofu Hou | 2023 | Journal of Energy Chemistry2023，，8： | 0 |
| 10 | Experimental search for high-performance ferroelectric tunnel junctions guided by machine learning显示文摘Ferroelectric tunnel junction(FTJ)has attracted considerable attention for its potential applications in nonvolatile memory and neuromorphic computing.However,the experimental exploration of FTJs with high ON/OFF ratios is a challenging task due to the vast search space comprising of ferroelectric and electrode materials,fabrication methods and conditions and so on.Here,machine learning(ML)is demonstrated to be an effective tool to guide the experimental search of FTJs with high ON/OFF ratios.A dataset consisting of 152 FTJ samples with nine features and one target attribute(i.e.,ON/OFF ratio)is established for ML modeling.Among various ML models,the gradient boosting classification model achieves the highest prediction accuracy.Combining the feature importance analysis based on this model with the association rule mining,it is extracted that the utilizations of{graphene/graphite(Gra)(top),LaNiO_(3)(LNO)(bottom)}and{Gra(top),Ca_(0.96)Ce_(0.04)MnO_(3)(CCMO)(bottom)}electrode pairs are likely to result in high ON/OFF ratios in FTJs.Moreover,two previously unexplored FTJs:Gra/BaTiO_(3)(BTO)/LNO and Gra/BTO/CCMO,are predicted to achieve ON/OFF ratios higher than 1000.Guided by the ML predictions,the Gra/BTO/LNO and Gra/BTO/CCMO FTJs are experimentally fabricated,which unsurprisingly exhibit≥1000 ON/OFF ratios(~8540 and~7890,respectively).This study demonstrates a new paradigm of developing high-performance FTJs by using ML. | Jingjing Rao Zhen Fan Qicheng Huang Yongjian Luo Xingmin Zhang Haizhong Guo Xiaobing Yan Guo Tian Deyang Chen Zhipeng Hou Minghui Qin Min Zeng Xubing Lu Guofu Zhou Xingsen Gao Jun-Ming Liu | 2022 | Journal of Advanced Dielectrics2022，12，3： | 0 |
| 11 | Simulation and optimization of dopant-free asymmetric heterojunction solar cells显示文摘In order to further study doping-free asymmetric heterojunction(DASH) solar cells,we used AFORS-HET software to optimize the structure of Al/SnO_(2)/a-Si:H(i)/c-Si(p)/a-Si:H(i)/NiO_(x)/Ag.In a certain adjustment range,a series of simulations were carried out on the band gap,electron affinity,thickness and work function(WF) of NiO_(x),thickness and WF of SnO_(2),and the thickness of a-Si:H(i).After the above optimization,21.08% efficiency was obtained at 300 K.This study shows that the solar cells with this structure have good light absorption properties in a very wide spectrum.The present simulation provides instructive suggestions for follow-up experiments of DASH solar cells. | ZHENG Qiaoqiao YUAN Yujie HOU Guofu LI Wei TAO Ke PENG Zhuo | 2023 | Optoelectronics Letters2023，19，6： | 0 |
| 12 | Effects of guanidinium cations on structural,optoelectronic and photovoltaic properties of perovskites显示文摘Guanidinium(GA)cations are intentionally introduced in MAPbI_(3) perovskite by considering its potential capability of stabilizing the material through plenty of hydrogen bonds and mitigating hysteresis because of the zero dipole moment.The configurations of GA cation in film and its effects on structural,optoelectronic and photovoltaic properties of perovskite have been comprehensively studied by systematically modulating the GA ratio.It has been demonstrated that moderate GA cations can effectively passivate the defect surrounding perovskite grains,yielding an enhanced efficiency as high as~19,2%in a p-i-n type planar solar cells with the GA ratio of 15%.Further increasing the GA ratio deteriorates device performance,as extra GA cations hinder grain growth and thus reduce the grain size,which facilitates the defect generation around the enhanced interface.Moreover,a new two-dimensional(2 D)layered perovskite phase that features alternating GA and MA cations in the interlayer space(ACI)appears ultimately,while the ACI phase typically suffers from slow charge transportation across the parallel PbI2 octahedral layers separated by large A-site cations. | Yi Ding Yan Wu Ying Tian Yuzeng Xu Minna Hou Bo Zhou Jingshan Luo Guofu Hou Ying Zhao Xiaodan Zhang | 2021 | Journal of Energy Chemistry2021，30，7： | 0 |
| 13 | Multi-peak spectrum of KML Ti:sapphire pulse显示文摘The multi-peak spectrum of Ti: sapphire pulses observed experimentally under ultra-broad bandwidth conditions ( < 15 fs pulse length) has been explained theoretically. It is shown that the self-phase-modulation effect is equivalent to the process of degenerate four-wave frequency-mixing. Based on this theoretical underpinning, the presence or absence of a multipeak spectrum provides a practical measure of whether the intracavity group-velocity-dispersion is ideally compensated for or not. | Shanghong Zhao Yishan Wang Guofu Chen Xianhua Wang Xun Hou | 1999 | Chinese Science Bulletin1999，44，8： | 0 |
