Zhu Shi Wei,Zhang Xiao Guo,Lv Jia Dong,Wang Qing 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.1

Aiming at solving problem of points’ redundancy caused by full automatically detecting points and the problem of large workload caused by picking all points manually, I advanced a new method of picking points which is based on Human-Computer Interaction in our 3D reconstruction platform after automatically detecting points. We first detected and matched points automatically and got the homograph matrix between two images, then projected points which were picked by hand on the one image to the other image, at last we would search the interesting feature points in the neighborhood of corresponding points in the two images. Experiments have shown that this method decreases the redundancy brought by large number of points and successfully finds the important feature points, so it lays a good foundation for 3D reconstruction.

秦漢“畏耎”犯罪探究

Xiao Zhu(朱瀟) 경북대학교 아시아연구소 2014 아시아연구 Vol.- No.20

본고는 岳麓奏簡인 『爲獄等狀四種』의 ‘綰等畏耎還走案’을 기본 자료로 삼고 기타 전해지거나 출토된 법률 문헌과 결합하여 진한 시기 ‘畏耎’ 범죄의 입법과 심판 진행에 대해 고찰하였다. ‘畏耎’ 범죄는 일반적으로 전쟁 중에 두려워서 배회하거나 공포로 도망가서 전투에 불리한 영향을 가져다주는 자들의 범죄 행위를 말한다. 이러한 범죄는 군대 관리와 국가의 군사 이익에 손해를 가져다주기 때문에 군사 범죄의 범주에 속한다. ‘綰等畏耎還走’는 奉代 전투원이 ‘畏耎還走’ 하여 범죄한 것에 대해 사법적으로 판단한 안건이다. 안건 기록과 관련 역사 자료를 통해 볼 때, 진한시기 ‘畏耎’ 범죄 행위에 대한 규정은 대체로 유사한데, 범죄 주체자는 모두 전투중인 장군과 사졸이고 범죄행위는 임전시 위축되어 배회하고 나아가 싸우지 않거나 도망한 것으로 나타났다, ‘畏耎’ 범죄의 형벌과 ‘儋乏不鬥’는 유사한데, 최고형은 참형이지만 상황의 경중에 근거하여 차별적으로 처벌하는 감등 원칙을 따랐다. ‘畏耎’ 범죄는 특수한 주체와 특수한 상황이라는 요구에 만족해야만 구성될 수 있기 때문에 그 성질과 ‘亡’죄의 존재는 크게 구별된다. ‘綰等畏耎還走案’에서 보는 바와 같이, 이러한 범죄의 審理절차와 보통 형사 안건이 거의 별 차이가 없다. 범죄는 지방 현급 官府에서 처리하는데 郡府에 보고하고 허락받아 집행하였다. 이로써 진대 지방 사법 절차는 대체적으로 유사하여 범죄 성질의 차이에 따라 구별되는 것은 아니라고 추측해 볼 수 있다. 주의해야 할 것은 명확하게 형벌을 적용하기 위해 관부는 ‘畏耎’ 범죄의 구체적인 정황에 대해 세밀하게 조사하고 검증할 필요가 있다. 이러한 審理추구는 진대가 극히 증거를 중시하는 논죄원칙을 보여준 것이다. ‘畏耎還走’ 죄는 泰代 문헌에 나타나는데, 漢代에도 ‘畏懦’나 ‘逗留畏懦’(‘畏懦逗留’)가 나타나며 이러한 범죄의 최고형량은 모두 사형이다. 奏漢시기 관련 율령은 魏晉隋唐시기에도 전승되었다. 비록 후자의 규정이 더욱 세밀하지만 그들의 입법정신에서는 고도로 일치한다고 할 수 있다. 국가의 다른 제도와 비교해 보았을 때 전쟁과 관련된 율령 법규는 장기적인 안정성을 유지하고 있는 것을 확인할 수 있다. The paper take “the case of Wan run from the battlefield” of four forms of descriptions for judicial laws in Yuelu Academy Collection-Qin Bamboo Slips as basic information, together with other transmitted accounts and archaeologically retrieved manuscripts, discus on the legislation and trial to the crime of “fear” in Qin and Han dynasties. The crime of “fear”, which always refer to the fighters stay in situ or run away because of fear and bring adverse effects to the combat situation, was the charge against criminal subjects belonging to special crimes with generals and soldiers in the battle accused. It was worth respectively discussing the conviction and punishment of special crimes due to its distinctiveness differing from that of normal crimes. This kind of crime which involved in military management and damage the national military’s interests belongs to the category of the military crime. Speculating from the case record and relevant historical materials, we could find that the regulations on the crime of “fear” are roughly similar in Qin dynasty: the subjects of crime are soldiers and officers, the criminal behaviors are represented to running away or staying in situ for fear. The penalty to the crime of “fear” is death sentence, which is similar to the crime of “Too Scared to Fight”, and could be mitigated According to the weight of the circumstances of the crime. It needs special subject and situation to constitute a crime of “fear”, thus it’s nature is very different from the fleeing crime(Wang). According to “the case of Wan run from the battlefield”, the trial procedure of “fear” criminal case has no difference from other criminal cases: the crime is accepted by local authorities and submitted to their seniors for consenting to the sentence. Perhaps we can speculate that the local trial procedure will not be different from the nature of the crimes. However it must be pointed out that, in order to clarify the appropriate penalty, the local authorities need to investigate crime scene meticulously. this trial requirements also reflect the principle of attaching great importance to the evidence in Qin Dynasty. The legislation of the “fear” crime of Qin and Han Dynasties has been inherited by the royal courts of Northern and Southern Dynasties, Sui and Tang Dynasties. These legal norms were highly consistent in the legislative spirit. Thus it can be seen, compared with other legal system of the country, the martial laws maintained long-term stability.

Zhu, Zhong-Zheng,Wang, Dong,Cong, Wen-Ming,Jiang, Hongmei,Yu, Yue,Wen, Bing-Ji,Dong, Hui,Zhang, Xiao,Liu, Shu-Fang,Wang, Ai-Zhong,Zhu, Guanshan,Hou, Lifang Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.1

Background: Males have a higher prevalence of hepatocellular carcinoma (HCC) than females in general, but the reasons for the sex disparity are still obscure. DNA copy number alteration (CNA) is a major feature of solid tumors including HCC, but whether CNA plays a role in sex-related differences in HCC development has never been evaluated. Methods: High-resolution array comparative genomic hybridization (CGH) was used to examine 17 female and 46 male HCC patients with chronic hepatitis B virus (HBV) infection in Shanghai, China. Two-tailed Fisher's exact or ${\chi}^2$ tests was used to compare CNAs between females and males. Results: The overall frequencies and patterns of CNAs in female and male cases were similar. However, female HCC tumors presented more copy number gains compared to those in males on 1q21.3-q22 (76.5% vs. 37.0%, P = 0.009), 11q11 (35.3% vs. 0.0%, P = 0.0002) and 19q13.31-q13.32 (23.5% vs. 0.0%, P = 0.004), and loss on 16p11.2 (35.3% vs. 6.5%, P = 0.009). Relative to females, male cases had greater copy number loss on 11q11 (63.0% vs. 17.6%, P = 0.002). Further analyses showed that 11q11 gain correlated with 19q13.31-q13.32 gain (P = 0.042), 11q11 loss (P = 0.011) and 16p11.2 loss (P = 0.033), while 1q21.3-q22 gain correlated with 19q13.31-q13.32 gain (P = 0.046). Conclusions: These findings suggest that CNAs may play a role in sex-related differences in HBVassociated HCC development.

First-Principles Study of the Elastic, Hardness and Electronic Properties of MoAlB under High Pressure

Xiao Ling Zhu,Wei Yang,Shan Shan Gao,Jin Ping Zhang 한국물리학회 2019 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.74 No.5

The structure, elastic and electronic properties of MoAlB have been studied under high pressure by using first principles. The optimized lattice parameters, elastic constants, bulk moduli, and shear moduli agree well with experimental and other theoretical values. The relationships of the lattice constants with pressure indicated an anisotropic behavior. The calculated elastic constants satisfy the mechanical stability conditions. Our calculated Vickers hardness of MoAlB is 11.56~GPa, which agrees with the experimental data and confirms its having a relatively softer nature than the other borides. The Cauchy pressure, the Poisson's ratio and the $G/B$ value suggest that MoAlB is a brittle solid under ambient conditions, but the brittleness decreases with increasing pressure. The band structure and the density of states reveal the metallic feature of MoAlB, and the energy levels shift toward both sides of the Fermi level with increasing pressure. The Mulliken population and density of states suggest a mixture bonding nature of covalence and metallicity in MoAlB.

( Xiao Juan Zhu ),( Shao Hui Wang ),( Ravi Jacob ),( Zhi Ning Fan ),( Fa Ming Zhang ),( Guo Zhong Ji ) 대한소화기기능성질환·운동학회 2011 Gut and Liver Vol.5 No.2

Background/Aims: Pyogenic liver abscess (PLA) is a serious, life threatening condition with a high mortality rate that represents a diagnostic and therapeutic challenge. The aim of this study was to collect demographic data and clinical, laboratory and microbiological characteristics of PLA patients treated between 2000 and 2010. We also aimed to collect information regarding our management experience of these cases. Methods: As a retrospective review, 47 patients with PLA in a tertiary referral center were examined to determine their demographic characteristics, clinical features, and laboratory, imaging, and microbiologic findings as well as the treatment outcome. Results: Cryptogenic PLA was the most frequently identified type of PLA, while benign biliary tract disease was the most frequently identifi able cause of PLA (18/47 patients; 38.3%). Leukocytosis and elevated alanine transaminase were common laboratory findings and were observed in 35 (74.5%) and 22 (46.8%) patients, respectively. Increased fibrinogen was also detected in 11 of 15 investigated cases (73.3%). Notably, infection-induced thrombocytopenia occurred in 8 patients (17%). Diabetes mellitus was associated with the occurrence of infection induced shock when compared to the non-diabetic group (p<0.05). Patients with two or more comorbid diseases had longer hospitalizations when compared to patients with one comorbid disease or those without comorbidities (p<0.001). The number of days needed to establish diagnosis was correlated with the length of hospitalization (p<0.001). The overall hospital mortality rate was 2.1% (1/47). Conclusions: Characteristics of PLA patients from the past 10 years are presented. The number of days needed to establish a PLA diagnosis was correlated with the length of the hospital stay. The hospital stay of PLA patients can be further improved by early diagnosis and effective treatments during the early stages of PLA progression. (Gut Liver 2011;5:221-227)

Taguchi Approach for Anti-heat Stress Prescription Compatibility in Mice Spleen Lymphocytes In Vitro

Xiao-yu Zhu,Gui-lin Cheng,Feng-hua Liu,Jin Yu,Yu-jie Wang,Tong-quan Yu,Jian-qin Xu,Ming Wang 대한약학회 2011 Archives of Pharmacal Research Vol.34 No.7

Heat stress (HS) may induce immunosuppression as well as inhibit the proliferation of lymphocytes. This study evaluated the effects on immune function of our prescription on splenic lymphocytes under HS as well as its compatibility. The effects of four herbal extracts from Agastache rugosa, Atractylodes lancea, Cortex Phellodendri, and Gypsum Fibrosum on heat treated splenic lymphocytes were investigated and the compatibility of the prescription was also explored by using the Taguchi method. This study revealed changes in proliferation by traditional Chinese medicines of splenic lymphocytes after HS. Proliferation in the HS group was significantly lower than the control group. Under HS, the effects of higher concentrations of Agastache rugosa (100 and 200 μg/mL), Atractylodes lancea (100 and 200 μg/mL), Cortex Phellodendri (50 and 100 μg/mL) and Gypsum Fibrosum (100 and 200 μg/mL) caused a significant increase on ConA/LPS-induced proliferation of lymphocytes than lower concentrations. We, therefore, conclude that the prescription of traditional Chinese medicines may recover splenic lymphocytes from the immunosuppression induced by HS. The Taguchi design, which allows rapid and high efficiency for the selection of the best conditions for our prescription on HS-treated splenic lymphocytes, demonstrated that Agastache rugosa (200 μg/mL), Atractylodes lancea (200 μg/mL), Cortex Phellodendri (100 μg/mL) and Gypsum Fibrosum (100 μg/mL)were the optimal conditions for the prescription. The validation experiment confirmed that our composition in optimum extraction conditions enhanced effects on ConA or LPS-stimulated lymphocytes under HS. The results showed that the Taguchi optimization approach is a suitable method for optimization of the composition of prescription.

Reliability assessment method based on the meta-action unit for complex mechanical system

Xiao Zhu,Yan Ran,Xinglong Li 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.3

In this paper, a functionality unit named as meta-action unit (MAU) is proposed to correlate the system function with the part actions and assess reliability of mechanical system. Firstly, the function of system is decomposed into multiple MAUs by function-movementaction (FMA). Then, the lifetime of MAU is fitted by Weibull distribution, and its parameters are estimated by support vector regression (SVR). In addition, taking the distributions of MAU as marginal distributions, the lifetime distribution of mechanical system is constructed by copula function to assess system reliability, and its parameters are estimated using the maximum likelihood estimator (MLE). Further, the reliability assessment accuracy based on MAU is compared with that from traditional method based on mechanical part failure modes. Finally, the reliability assessment of the indexing turntable (IT) is performed as an example to illustrate the feasibility and reasonability of the proposed method.

Xiao W. Ji,Ya L. Liao,Ye F. Zhu,Hai G. Wang,Ling Gu,Jiang Gu,Chen Dong,Hong L. Ding,Xu H. Mao,Feng C. Zhu,Quan M. Zou 한국미생물학회 2010 The journal of microbiology Vol.48 No.6

Escherichia coli O157:H7, an important food-borne pathogen, has become a major public health concern worldwide. The aim of this study was to investigate the molecular epidemiologic feature of E. coli O157:H7strains in China. 105 E. coli O157:H7 isolates were collected from various hosts and places over 9 years. A multilocus sequence typing scheme (MLST) was applied for bacteria genotyping and polymerase chain reaction (PCR) was used for virulence factor identification. Seven new MLST sequence types (STs), namely ST836, ST837, ST838, ST839, ST840, ST841, and ST842 were identified, which grouped into two lineages. Phylogenetic analysis suggested that the most two frequent STs in China, ST837 and ST836, may be the derivatives of E. coli O157:H7 Sakai or E. coli O157:H7 EDL933. Geographical diversity and host variety of E. coli O157:H7 were observed in China. In addition, the different distribution of tccp was detected. The data presented herein provide new insights into the molecular epidemiologic feature of E. coli O157:H7, and aid in the investigation of the transmission regularity and evolutionary mechanism of E. coli O157:H7.
