| 1 | Theoretical study on Manson-Coffin equation for physically short cracks and lifetime prediction显示文摘The Manson-Coffin equation has been widely applied to the prediction of fatigue lifetime.But this equation does not explicitly express the relation between the fatigue lifetime and the crack length.The present paper proposes that the grain size can be re-placed by the maximum non-damaging crack length.Thus,the growth rate will decrease to zero when the crack reaches this size.Combining with the theory of the fatigue short crack propagation,we derived the relations between physically short crack's initiation-propagation rates and material's mechanical properties,as well as crack length,stress and strain.With the derived relations,fatigue lifetime of short cracks can be successfully predicted by basic mechanical properties.Similar to the format of Manson-Coffin equation,our relations uncover the essence of Manson-Coffin equation which may reveal the short crack's initiation-propagation mechanism.Predictions of fatigue lifetime using our relations were compared with the results of well-known experiments.Good agreement is found in many aspects,such as coefficients,exponents,as well as fatigue life-times,especially for short cracks around 10 micrometers.Predictions on the short crack propagation rates are also compared for 16 types of carbon steels.Satisfactory consistency shows that our relations have wide applicability. | HU YanDong HU ZhiZhong CAO ShuZhen | 2012 | Science China(Technological Sciences)2012，55，1： | 14 |
| 2 | Spatial and temporal variability of heat content above the thermocline in the tropical Pacific Ocean显示文摘Heat content of the upper layer above the 20℃ isotherm in the tropical Pacific Ocean is estimated by using the sea temperature data set with a resolution 2°latitude × 5°longitude (1980~1993) for the water depths (every 10 m) from 0 m to 400 m, and its temporal and spatial variabilities are analyzed. ( 1 ) The temporal variability indicates that the total heat in the upper layer of the equatorial Pacific Ocean is characterized by the interannual variability. The time series of the equatorial heat anomaly 5 months lead that of the El Nino index at the best positive lag correlation between the two, and the former 13 months lag behind the latter at their best negative lag correlation. Therefore the equatorial heat content can be used as a better predictor than the El Nino index for a warm or cold event. In addition, it is also found that less heat anomaly in the equator corresponds to the stronger warm events in the period (1980~1993) and much more heat was accumulated in the 4 years including 1992/1993 ENSO (1989~1993) than the 4 years including 1982/1983 ENSO (1980~1983); (2) The spatial variability indicates that the area with the highest lag correlation among the grids moves in an anti-clockwise circle in the northern tropical Pacific Ocean within 4 years period and in a clockwise circle in the southern tropical Pacific Ocean. This result provides scientific evidence for the quasi - cycle theory of El Nino events. | Pu Shuzhen, Yu Fei, Hu Xiaomin, Chen Xingrong First Institute of Oceanography, State Oceanic Administration, Qingdao 266061,China, | 2003 | Acta Oceanologica Sinica2003，22，2： | 6 |

| 4 | Numerical Investigation of a High-subsonic Axial-flow Compressor Rotor with Non-axisymmetric Hub Endwall显示文摘The major source of loss in modern compressors is the secondary loss.Non-axisymmetric endwall profile contouring is now a well established design methodology in axial flow turbines.However,flow development in axial compressors is differ from turbines,the effects of non-axisymmetric endwall to axial compressors requires flow analysis in detail.This paper presents both experimental and numerical data to deal with the application of a non-axisymmetric hub endwall in a high-subsonic axial-flow compressor.The aims of the experiment here were to make sure the numerically obtained flow fields is the physical mechanism responsible for the improvement in efficiency,due to the non-axisymmetric hub endwall.The computational results were first compared with available measured data of axisymmetric hub endwall.The results agreed well with the experimental data for estimation of the global performance.The coupled flow of the compressor rotor with non-axisymmetric hub endwall was simulated by a state-of-the-art multi-block flow solver.The non-axisymmetric hub endwall was designed for a subsonic compressor rotor with the help of sine and cosine functions.This type of non-axisymmetric hub endwall was found to have a significant improvement in efficiency of 0.45% approximately and a slightly increase for the total pressure ratio.The fundamental mechanisms of non-axisymmetric hub endwall and their effects on the subsonic axial-flow compressor endwall flow field were analyzed in detail.It is concluded that the non-axisymmetric endwall profiling,though not optimum,can mitigate the secondary flow in the vicinity of the hub endwall,resulting in the improvement of aerodynamic performance of the compressor rotor. | Shuzhen Hu Xingen Lu Hongwu Zhang Junqiang Zhu Qiang Xu | 2010 | Journal of Thermal Science2010，19，1： | 4 |
| 5 | IAP's Solar-Powered Unmanned Surface Vehicle Actively Passes through the Center of typhoon Sinlaku(2020)显示文摘The solar-powered marine unmanned surface vehicle(USV) developed by the USV team of the Institute of Atmospheric Physics is a rugged, long-duration, and autonomous navigation vessel designed for the collection of longrange, continuous, real-time, meteorological and oceanographic measurements, especially under extreme sea conditions(sea state 6–7). These solar-powered USVs completed a long-term continuous navigation observation test over 26 days.During this time, they coordinated double-USV observations and actively navigated into the path of Typhoon Sinlaku(2020) before collecting data very close to its center during the 2020 USV South China Sea Typhoon Observation Experiment. Detailed high temporal resolution(1 min) real-time observations collected by the USV on the typhoon were used for operational typhoon forecasting and warning for the first time. As a mobile meteorological and oceanographic observation station capable of reliable, automated deployment, data collection, and transmission, such solar-powered USVs can replace traditional observation platforms to provide valuable real-time data for research, forecasting, and early warnings for potential marine meteorological disasters. | Hongbin CHEN Jun LI Wenying HE Shuqing MA Yingzhi WEI Jidong PAN Yu ZHAO Xuefen ZHANG Shuzhen HU | 2021 | Advances in Atmospheric Sciences2021，38，4： | 2 |

| 7 | Geochemistry, U-Pb Geochronology and Sr-Nd-Hf Isotopes of the Early Cretaceous Volcanic Rocks in the Northern Da Hinggan Mountains显示文摘Whole-rock geochemical, zircon U-Pb geochronological and Sr-Nd-Hf isotopic data are presented for the Early Cretaceous volcanic rocks from the northern Da Hinggan Mountains. The volcanic rocks generally display high SiO2(73.19–77.68 wt%) and Na2O+K2O(6.53–8.98 wt%) contents, with enrichment in Rb, Th, U, Pb and LREE, and depletion in Nb, Ta, P and Ti. Three rhyolite samples, one rhyolite porphyry sample, and one volcanic breccia sample yield weighted mean 206Pb/238 U ages of 135.1±1.2 Ma, 116.5±1.1 Ma, 121.9±1.0 Ma, 118.1±0.9 Ma and 116.9±1.4 Ma, respectively. All these rocks have moderate(87Sr/86Sr)i values of 0.704912 to 0.705896, slightly negative εNd(t) values of –1.4 to –0.1, and positive εHf(t) values of 3.7 to 8. Their zircon Hf and whole-rock Nd isotopic model ages range from 594 to 1024 Ma. These results suggest that the Early Cretaceous volcanic rocks were originated from melting of subducted oceanic crust and associated sediments during the closure of the Mongol-Okhotsk Ocean. | HU Xinlu YAO Shuzhen HE Mouchun DING Zhenju CHEN Bin | 2015 | Acta Geologica Sinica(English Edition)2015，89，1： | 2 |

| 12 | Design of a novel chimeric peptide via dual blockade of CD47/SIRPαand PD-1/PD-L1 for cancer immunotherapy显示文摘Although immune checkpoint inhibition has been shown to effectively activate antitumor immunity in various tumor types,only a small subset of patients can benefit from PD-1/PD-L1 blockade.CD47 expressed on tumor cells protects them from phagocytosis through interaction with SIRPαon macrophages,while PD-L1 dampens T cell-mediated tumor killing.Therefore,dual targeting PD-L1 and CD47 may improve the efficacy of cancer immunotherapy.A chimeric peptide Pal-DMPOP was designed by conjugating the double mutation of CD47/SIRPαblocking peptide(DMP)with the truncation of PD-1/PD-L1 blocking peptide OPBP-1(8-12)and was modified by a palmitic acid tail.Pal-DMPOP can significantly enhance macrophage-mediated phagocytosis of tumor cells and activate primary T cells to secret IFN-γin vitro.Due to its superior hydrolysis-resistant activity as well as tumor tissue and lymph node targeting properties,Pal-DMPOP elicited stronger anti-tumor potency than Pal-DMP or OPBP-1(8-12)in immune-competent MC38 tumor-bearing mice.The in vivo anti-tumor activity was further validated in the colorectal CT26 tumor model.Furthermore,Pal-DMPOP mobilized macrophage and T-cell anti-tumor responses with minimal toxicity.Overall,the first bispecific CD47/SIRPαand PD-1/PD-L1 dual-blockade chimeric peptide was designed and exhibited synergistic anti-tumor efficacy via CD8^(+)T cell activation and macrophage-mediated immune response.The strategy could pave the way for designing effective therapeutic agents for cancer immunotherapy. | Zheng Hu Wanqiong Li Shaomeng Chen Danhong Chen Ran Xu Danlu Zheng Xin Yang Shuzhen Li Xiuman Zhou Xiaoshuang Niu Youmei Xiao Zhuoying He Huihao Li Juan Liu Xinghua Sui Yanfeng Gao | 2023 | Science China(Life Sciences)2023，66，10： | 1 |

| 16 | Isogeometric analysis of multi-patch solid-shells in large deformation显示文摘In the context of isogeometric analysis(IGA)of shell structures,the popularity of the solid-shell elements benefit from formulation simplicity and full 3D stress state.However some basic questions remain unresolved when using solid-shell element,especially for large deformation cases with patch coupling,which is a common scene in real-life simulations.In this research,after introduction of the solid-shell nonlinear formulation and a fundamental 3D model construction method,we present a non-symmetric variant of the standardNitsche’s formulation for multi-patch coupling in associationwith an empirical formula for its stabilization parameter.An selective and reduced integration scheme is also presented to address the locking syndrome.In addition,the quasi-Newton iteration format is derived as solver,together with a step length control method.The second order derivatives are totally neglected by the adoption of the non-symmetric Nitsche’s formulation and the quasi-Newton solver.The solid-shell elements are numerically studied by a linear elastic plate example,then we demonstrate the performance of the proposed formulation in large deformation,in terms of result verification,iteration history and continuity of displacement across the coupling interface. | Qingyuan Hu Davide Baroli Shuzhen Rao | 2021 | Acta Mechanica Sinica2021，37，5： | 1 |

| 18 | Improved Diamond Search Algorithm for H.264/AVC Video Coding Standard显示文摘Diamond search (DS) is an excellent fast block match- ing motion estimation (BMME) algorithm. In this paper, we pro- pose an improved diamond search (IDS) algorithm, which revises the two search patterns of DS. The proposed algorithm is com- pared with several mainstream algorithms. The simulation results show that the proposed algorithm over DS can be up to 20% gain on speedup on average, while maintain the similar or even better quality, both objectively and subjectively. The proposed algorithm is also competitive with other fast algorithms. | HU Feng LIU Jia CHEN Shuzhen | 2008 | Wuhan University Journal of Natural Sciences2008，13，1： | 0 |
| 19 | Drivers of elevation-dependent warming over the Tibetan Plateau显示文摘青藏高原(海拔≥3000 m地区)对全球气候变化的变暖响应是空间不均匀的,其增温幅度会随着海拔升高而增大,被称为海拔依赖性增温.青藏高原海拔依赖性增温具有季节依赖性,在冬季最为显著,达0.21℃km-1.在以往的研究中,众多因素被认为是青藏高原海拔依赖性增温的可能驱动因素,但关于这些因素相对重要性的研究较少.基于多个数据集,本文应用辐射核(radiative kernel)技术方法定量诊断了近几十年(1979-2018年)冬季不同物理过程对青藏高原海拔依赖性增温的贡献.结果表明,与积雪变化相关的地表反照率反馈在其中起主导作用.观测数据分析显示,在过去40年的冬季,高海拔地区的积雪覆盖率显著减少,导致地表反射的短波辐射减少,从而促进了海拔依赖性增温. | Shuzhen Hu Pang-Chi Hsu | 2023 | Atmospheric and Oceanic Science Letters2023，16，2： | 0 |
| 20 | A Two-Layer Real-Time Rate Control Algorithm Based on Lagrange Optimum Algorithm显示文摘Because of the iterative process in the rate control algorithm of the H.264 draft, it is not suitable for real-time trans-mission. A two-layer real-time rate control algorithm based on the Lagrange optimum algorithm is proposed. This algorithm consists of two layers, namely, the group of pictures (GOP) layer and the frame layer. The simulation results show that the proposed algo-rithm is competitive in terms of peak signal-to-noise ratio (PSNR), real bitrates and the Q-value among frames over the original algo-rithm. | HU Feng LIU Jia CHEN Shuzhen | 2009 | Wuhan University Journal of Natural Sciences2009，14，1： | 0 |
