| 1 | Software Backdoor Analysis Based on Sensitive Flow Tracking and Concolic Execution显示文摘In order to effectively detect and analyze the backdoors this paper introduces a method named Backdoor Analysis based on Sensitive flow tracking and Concolic Execution(BASEC).BASEC uses sensitive flow tracking to effectively discover backdoor behaviors, such as stealing secret information and injecting evil data into system, with less false negatives. With concolic execution on predetermined path, the backdoor trigger condition can be extracted and analyzed to achieve high accuracy. BASEC has been implemented and experimented on several software backdoor samples widespread on the Internet, and over 90% of them can be detected. Compared with behavior-based and system-call-based detection methods, BASEC relies less on the historical sample collections, and is more effective in detecting software backdoors, especially those injected into software by modifying and recompiling source codes. | XU Xin WANG Jiajie CHENG Shaoyin ZHANG Tao JIANG Fan | 2016 | Wuhan University Journal of Natural Sciences2016，21，5： | 3 |

| 4 | Synthesis and electromagnetic wave absorption performances of a novel(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))_(3)AlC_(2)high-entropy MAX phase显示文摘Herein,a novel kind of high-entropy MAX phases,(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))_(3)AlC_(2)powders were success-fully synthesized by a newly proposed two-step solid state reaction process.The oxidation experiments demonstrate that the oxidation products of Al_(2)Mo_(3)O_(12) and rutile TiO 2 are formed at about 600 and 800℃,respectively.Besides,the dielectric and electromagnetic(EM)wave absorption properties of(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))_(3)AlC_(2)powders and those after oxidation at different temperatures were also exam-ined.The results show that the as-synthesized(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))_(3)AlC_(2)powders possess excellent EM wave absorption performances with the minimum reflection loss(RL)of-45.80 dB(at 1.7 mm thickness)and the maximum effective absorption bandwidth(E AB)of 3.6 GHz(at 1.5 mm thickness).After oxidation at 400-800℃,due to the coupling of conductivity loss and polarization loss,(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))_(3)AlC_(2)powders can retain good EM wave absorption properties in a certain frequency range.In this paper,the effects of oxidation on EM wave absorption properties of high-entropy MAX phases were systematically investigated for the first time.This work manifests that high-entropy MAX phases are promising EM wave absorbing candidates and can maintain good EM wave absorption performances after oxidation. | Linjing Qiao Jianqiang Bi Guandong Liang Chen Liu Zhuangzhuang Yin Yao Yang Hongyi Wang Shaoyin Wang Mengmeng Shang Weili Wang | 2023 | Journal of Materials Science & Technology2023，，6： | 1 |
| 5 | Synthesis of high-entropy MXenes with high-efficiency electromagnetic wave absorption显示文摘High-entropy MXenes,as a new emerging class of materials,possess diverse compositions,unexpected physicochemical characteristics,and great potentials for electromagnetic(EM)wave absorption.Herein,two single-to-few-layer high-entropy MXenes,(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))3 C2 T_(x)and(Mo_(0.2)Cr_(0.2)Nb_(0.2)Ti_(0.2)V_(0.2))_(4)C_(3)T_(x),were synthesized for the first time.During the exfoliation and delamination processes,the structural,morphological,and compositional evolutions were analyzed,verifying the successful formation of single-to-few-layer two-dimensional MXene nanosheets.Investigations indicate that with the filling content of only 35 wt%,MXene powder filled composites exhibit high-efficiency EM wave absorption performances.The f-(Mo_(0.25)Cr_(0.25)Ti_(0.25)V_(0.25))_(3)C_(2)T_(x)possesses the minimum reflection loss(RL min)of−45.0 dB with the matching thickness of 1.52 mm and the maximum effective absorption bandwidth(EAB)of 5.6 GHz at 1.65 mm thickness.Also,f-(Mo_(0.2)Cr_(0.2)Nb_(0.2)Ti_(0.2)V_(0.2))_(4)C_(3)T_(x)can attain an RL min of−52.8 dB with the thickness of 1.58 mm and an optimum EAB value of 3.6 GHz at 1.50 mm.The satisfactory EM wave absorption efficiency and bandwidth,thin matching thickness,and low filling content prove the lightweight advantage and great application potential of high-entropy MXenes in EM wave absorption.In this work,the high-entropy strategy is applied to tune the EM wave absorption performances for MXenes.Furthermore,high-entropy engineering is expected to provide control and tunability of many other properties,such as electrochemical,catalytic,and mechanical behaviors. | Linjing Qiao Jianqiang Bi Guandong Liang Yao Yang Hongyi Wang Shaoyin Wang | 2023 | Journal of Advanced Ceramics2023，12，10： | 0 |
| 6 | Separation of Atmospheric Circulation Patterns Governing Regional Variability of Arctic Sea Ice in Summer显示文摘In recent decades,Arctic summer sea ice extent(SIE)has shown a rapid decline overlaid with large interannual variations,both of which are influenced by geopotential height anomalies over Greenland(GL-high)and the central Arctic(CA-high).In this study,SIE along coastal Siberia(Sib-SIE)and Alaska(Ala-SIE)is found to account for about 65%and 21%of the Arctic SIE interannual variability,respectively.Variability in Ala-SIE is related to the GL-high,whereas variability in Sib-SIE is related to the CA-high.A decreased Ala-SIE is associated with decreased cloud cover and increased easterly winds along the Alaskan coast,promoting ice-albedo feedback.A decreased Sib-SIE is associated with a significant increase in water vapor and downward longwave radiation(DLR)along the Siberian coast.The years 2012 and 2020 with minimum recorded ASIE are used as examples.Compared to climatology,summer 2012 is characterized by a significantly enhanced GL-high with major sea ice loss along the Alaskan coast,while summer 2020 is characterized by an enhanced CA-high with sea ice loss focused along the Siberian coast.In 2012,the lack of cloud cover along the Alaskan coast contributed to an increase in incoming solar radiation,amplifying ice-albedo feedback there;while in 2020,the opposite occurs with an increase in cloud cover along the Alaskan coast,resulting in a slight increase in sea ice there.Along the Siberian coast,increased DLR in 2020 plays a dominant role in sea ice loss,and increased cloud cover and water vapor both contribute to the increased DLR. | Shaoyin WANG Jiping LIU Xiao CHENG Richard JGREATBATCH Zixin WEI Zhuoqi CHEN Hua LI | 2023 | Advances in Atmospheric Sciences2023，40，12： | 0 |
| 7 | An ESR Study on Singlet Oxygen Photoproduction of the Meso-Tetrakis-(Substituted Phenyl) Porphine Derivatives显示文摘The ability of meso-tetrakis- (substituted phenyl) porphine derivatives for photo-generating singlet oxygen (O2) is studied by ESR spectrometry. The results show that the singlet oxygen yields of most of porphine derivatives are higher than that of HPD. It is also exhibited that the nature and structure of the substituent at the meso position are closely related to the photo-sensitizing ability of meso-tetrakis-(substituted phenyl) porphine. | Chen Jiyao, -Lu Yameng, Chen Shiming and Cai Hualxin (Department of Physics and Center of Analysis and Measurements, Fudan University, Shanghai)Xu Deyu and Wang Shaoyin (Research Laboratory of Antimalaria Pharmaceuticals, No. 2 Military Medical University, Shanghai) | 1990 | Chemical Research in Chinese Universities1990，6，4： | 0 |
