SPECTRAL INEQUALITIES OF THE LAPLACIAN ON A CURVED TUBE WITH VARYING CROSS SECTION

Mao, Jing,Hou, Lanbao Korean Mathematical Society 2013 대한수학회논문집 Vol.28 No.1

In this note, we consider a curved tube with varying cross-section formed by rotating open bounded Euclidean domains with respect to a reference curve, and successfully give a lower bound to the threshold of the Laplacian on the tube, subject to Dirichlet boundary conditions on the surface and Neumann conditions at the ends of the tube. This generalizes the corresponding result in [1].

Accumulated evidence has indicated that Ephrin A1 (EFNA1) is associated with angiogenesis and tumorigenesis in various types of malignancies, including colorectal cancer (CRC). In the current study, we performed an online search using the public microarray database to investigate whether EFNA1 expression might be altered in CRC tissues. We then conducted a case-control study including 306 subjects (102 cases and 204 well-matched controls) in Xiaoshan County to assess any association between genetic polymorphisms in EFNA1 and CRC susceptibility. Searches in the Oncomine expression profiling database revealed EFNA1 to be overexpressed in CRC tissue compared with adjacent normal tissue. The rs12904 G-A variant located in the 3' untranslated region (UTR) of EFNA1 was observed to be associated with CRC susceptibility. Compared with the AA homozygous genotype, those carrying GA genotype had a decreased risk of developing CRC (odds ratio (OR)=0.469, 95% confidence interval (CI): 0.225-0.977, and P=0.043). The association was stronger among smokers and tea drinkers, however, no statistical evidence of interaction between rs12904 polymorphism and smoking or tea drinking on CRC risk was found. Our results suggest that EFNA1 is involved in colorectal tumorigenesis, and rs12904 A>G polymorphism in the 3' UTR of EFNA1 is associated with CRC susceptibility. Larger studies and further mechanistic investigations are warranted to confirm our findings.

MONOTONICITY OF THE FIRST EIGENVALUE OF THE LAPLACE AND THE p-LAPLACE OPERATORS UNDER A FORCED MEAN CURVATURE FLOW

Mao, Jing Korean Mathematical Society 2018 대한수학회지 Vol.55 No.6

In this paper, we would like to give an answer to Problem 1 below issued firstly in [17]. In fact, by imposing some conditions on the mean curvature of the initial hypersurface and the coefficient function of the forcing term of a forced mean curvature flow considered here, we can obtain that the first eigenvalues of the Laplace and the p-Laplace operators are monotonic under this flow. Surprisingly, during this process, we get an interesting byproduct, that is, without any complicate constraint, we can give lower bounds for the first nonzero closed eigenvalue of the Laplacian provided additionally the second fundamental form of the initial hypersurface satisfies a pinching condition.

Subcarrier and Power Allocation for Multiuser MIMO-OFDM Systems with Various Detectors

( Jing Mao ),( Chen Chen ),( Lin Bai ),( Haige Xiang ),( Jinho Choi ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.10

Resource allocation plays a crucial role in multiuser multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) systems to improve overall system performance. While previously proposed resource allocation algorithms are mainly designed from the point of view of the information-theoretic, we formulate the resource allocation problem as an average bit error rate (BER) minimization problem subject to a total power constraint when considering employing realistic MIMO detection techniques. Subsequently, we derive the optimal subcarrier and power allocation algorithms for three types of well-known MIMO detectors, including the maximum likelihood (ML) detector, linear detectors, and successive interference cancellation (SIC) detectors. To reduce the complexity, we also propose a two-step suboptimal algorithm that separates subcarrier and power allocation for each detector. We also analyze the diversity gain of the proposed suboptimal algorithms for various MIMO detectors. Simulation results confirm that the proposed suboptimal algorithm for each detector can achieve a comparable performance with the optimal allocation with a much lower complexity. Moreover, it is shown that the suboptimal algorithms perform better than the conventional algorithms that are known in the literature.

Xiangzhao Mao,Jing Zhang,Feifei Kan,Yuansong Gao,Jing Lan,Xiaowei Zhang,Zengmiao Hu,Yujin Li,Hong Lin 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.4

Fermentation of shrimp head was conducted using Streptococcus thermophilus to produce antioxidant and recover chitin. Fermentation conditions were found to be 10% shrimp head concentration, 5% glucose concentration,1.2%(v/v) inoculum size, and 64 h of incubation time at 42oC to attain an initial pH of 5.00 with response surface method optimization and the actual deproteinization rate obtained was 93.59%. Antioxidant activity in the supernatant fluid increased greatly during fermentation, the DPPH radical scavenging ability of the culture supernatant was about 98.70%. The concent-ration of astaxanthin, phenolic compounds, and free amino acid in the culture supernatant was 1.774 μg/mL, 589.69 μg gallic acid equivalents/mL, and 796.978mg/mL, respectively. Comparison of the FT-IR spectra and X-ray diffraction (XRD) analysis among commercial chitin (CTa), chitin prepared by the S. thermophilus fermentation (CTb), and chitin prepared by chemical treatments (CTc) demonstrated that CTb had the highest degree of deacetylation.

모정(毛靜,Mao Jing),박현규(朴現圭,Park Hyun-kyu) 순천향대학교 이순신연구소 2017 이순신연구논총 Vol.- No.27

본 논문은 조선 이순신이 중국에서 알려진 제반 모습과 흐름에 대해 분석한 글이다. 이순신은 임진왜란에서 바다에서 일본군을 물리친 민족 영웅이고, 한반도에서 가장 저명한 역사인물 중의 한 분이 되었다. 이웃 중국에서도 비교적 높은 지명도를 가졌다. 임진왜란 당시 조선 명장 이순신은 여러 해상 전투에서 일본수군을 물리쳐서 명나라 군사들에게 강한 인상을 주었다. 명 조정의 ≪명실록(明實錄)≫에서 조선 이순신을 본국에서 표창하라는 말을 남겼다. 학자와 중국에 망명한 한국 애국지사들이 임진왜란 때 완승을 거둔 이순신을 다시 주목하였다. 1949년 중화인민공화국이 수립된 이후 이순신을 주로 국제외교와 정치적의 입장에서 바라보았다. 1992년 한중 수교를 전후하여 양국 관계가 정상적인 궤도로 진입하고, 이와 동시에 이순신에 대한 연구와 보도가 심도 있고 다양한 면모를 보여 주고 있다. 앞으로 이순신과 임진왜란은 한중 양국의 우호교류를 이어주는 교량 역할을 할 것으로 믿어진다. 근대에 들어와서 조선과 중국은 내우외환을 함께 겪었다. 중국학자와 중국에 망명한 한국 애국지사들이 임진왜란 때 완승을 거둔 이순신을 다시 주목하였다. 1949년 중화인민공화국이 수립된 이후 이순신을 주로 국제외교와 정치적의 입장에서 바라보았다. 1992년 한중 수교를 전후하여 양국 관계가 정상적인 궤도로 진입하고, 이와 동시에 이순신에 대한 연구와 보도가 심도 있고 다양한 면모를 보여 주고 있다. 앞으로 이순신과 임진왜란은 한중 양국의 우호교류를 이어주는 교량 역할을 할 것으로 믿어진다. This article analyzed on the spreads and influence of Yi Sun Sin in China. Yi Sun Sin is the national hero, defeating Japanese army in the naval battle, being one of the famous historical people in Korea. He also had a relatively high reputation in China. During the Japanese invasion of Korea in 1592, Yi Sun Sin defeated the Japanese naval forces in several naval battles and made a strong impression on the Ming army. According to Ming shilu(明實錄), Ming government let Joseon dynasty appreciate and honor Admiral Yi Sun Sin. In the modern era, both Joseon and China experienced both internal and external troubles. Chinese scholars and Korean patriots, exiled to China brought the spotlight back onto Admiral Yi Sun Sin. Since the People s Republic of China was established in 1949, Yi Sun Sin was looked mainly from the perspective of international diplomacy and politics. Since the establishment of diplomatic relations between Korea and China in 1992, the relations between the two countries became normalized, and many in-depth researches on Yi Sun Sin have been carried on. Yi Sun Sin and the Japanese invasion of Korea in 1592 may play a role as a bridge between Korea and China.

Zhou, De,Xie, Wan-Zhuo,Hu, Ke-Yue,Huang, Wei-Jia,Wei, Guo-Qing,He, Jing-Song,Shi, Ji-Min,Luo, Yi,Li, Li,Zhu, Jing-Jing,Zhang, Jie,Lin, Mao-Fang,Ye, Xiu-Jin,Cai, Zhen,Huang, He Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.2

Aim: To analyze the significance of different clinical factors for prognostic prediction in diffuse large B-cell lymphoma (DLBCL) patients. Methods: Two hundred and twenty-seven DLBCL patients were retrospectively reviewed. Patients were managed with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen or rituximab plus the CHOP (RCHOP) regimen. Results: Lactate dehydrogenase (LDH), ${\beta}2$-microglobulin (${\beta}2$-M), B symptoms, Ann Arbor stage and genetic subtypes were statistically relevant in predicting the prognosis of the overall survival (OS). In the CHOP group, the OS in patients with germinal center B-cell-like (GCB)(76.2%) was significantly higher than that of the non-GCB group (51.9%, P=0.032). With RCHOP management, there was no statistical difference in OS between the GCB (88.4%) and non-GCB groups (81.9%, P=0.288). Conclusion: Elevated LDH and ${\beta}2$-M levels, positive B symptoms, Ann Arbor stage III/IV, and primary nodal lymphoma indicate an unfavorable prognosis of DLBCL patients. Patients with GCB-like DLBCL have a better prognosis than those with non-GCB when treated with the CHOP regimen. The RCHOP treatment with the addition of rituximab can improve the prognosis of patients with DLBCL.
