  • MCD: A Joint Semantic Project on East Asian Languages

    Hong Zhu   Yang Liu  

    The Multilingual Concept Dictionary is a NSFC/KOSEF joint project for natural language processing, now in its second year. The project’s key feature is to merge and align various ontologies and lexical resources of East Asian languages into a compatible one, especially for Chinese, Korean and Japanese. This paper as a progress report first introduces our new knowledge representation method for ontology construction, which is called “Upper Ontology Tree” plus “Lexical Semantics N-tuples”, and then analyzes the design of our dictionary framework especially the higher-level part, in which Korean and Japanese ontologies are mapped to the shared semantic hierarchy by semi-automatic methods.

  • Tuina for leg length discrepancy and lumbosacral pain due to sacroiliac joint subluxation

    Zhao-xing Zhang   Hong Zhu   Rui-hui Wang   Xu Du…  

    To observe the clinical effect of tuina reduction manipulation on leg length discrepancy and lumbosacral pain due to sacroiliac joint subluxation. A total of 60 eligible cases were randomly allocated into an observation group and a control group, 30 in each group. Cases in the observation group were treated with conventional tuina plus reduction manipulation of sacroiliac joint subluxation; whereas cases in the control group were treated with conventional tuina plus acupuncture. The clinical effects were observed after 10 times of treatment. In addition, the relapse rates were observed 2 months after treatment. The total effective rate in the observation group was 80.0%, versus 50.0% in the control group, showing a statistically significant difference (P<0.05). The relapse rate of lumbosacral pain in the observation group was 12.5%, versus 66.7% in the control group, showing a statistically significant difference (P<0.01). The relapse rate of leg length discrepancy in the observation group was 16.7%, versus 80.0% in the control group, showing a statistically significant difference (P<0.01). Tuina reduction manipulation can obtain substantial therapeutic effect for leg length discrepancy and lumbosacral pain due to sacroiliac joint subluxation, coupled with a low relapse rate.

  • Methanol-tolerant carbon aerogel-supported Pt–Au catalysts for direct methanol fuel cell

    Hong Zhu   Zhijun Guo   Xinwei Zhang   Kefei Han   Yubao Guo   Fanghui Wang   Zhongming Wang   Yongsheng Wei  

    Pt-Au nanoparticles supported on carbon aerogel, namely 2:1 has been synthesized by the microwave-assisted polyol process. The structure of Pt-Au nanoparticles is characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The electrochemical property of Pt-Au catalysts for methanol oxidation is evaluated by cyclic voltammetry (CV). The results show that Au-modified Pt catalysts exhibit a high methanol tolerance and improved electrochemical catalytic activity, suggesting that carbon aerogel supported Pt-Au catalysts are better catalysts for the electrochemical oxidation of methanol than conventional Pt catalysts.

  • CAMLE: A Caste-Centric Agent-Oriented Modelling Language and Environment

    Lijun Shan   Hong Zhu  

    This paper presents an agent-oriented modelling language and environment CAMLE. It is based on the conceptual model of multi-agent systems (MAS) proposed and formally defined in the formal specification language SLABS. It is caste-centric because the notion of caste plays the central role in its methodology. Caste is the classifier of agents in our language. It allows multiple and dynamic classifications of agents. It serves as the template of agents and can be used to model a wide variety of MAS concepts, such as roles, agent societies, etc. The language supports modelling MAS at both macro-level for the global properties and behaviours of the system and micro-level for properties and behaviours of the agents. The environment provides tools for constructing graphic MAS models in CAMLE, automatically checking consistency between various views and models at different levels of abstraction, and automatically transforming models into formal specifications in SLABS. The uses of the CAMLE modelling language and environment are illustrated by an example.

  • Method for early detection of magnetic head degradation due to carbon overcoat wear

    A method for detecting an impending failure of a disk drive system. The method includes monitoring a signal from a magnetoresistive sensor for the presence of a negative signal spike. A negative signal spike can indicate that the carbon overcoat of the magnetic medium has been locally worn off. The resulting localized absence of carbon overcoat causes the magnetoresistive sensor to short to the magnetic medium. This causes a short, abrupt drop in voltage, which can be used as evidence of the localized absence of the carbon overcoat. If such a negative signal spike is detected, the user can be notified of an impending system failure. In addition to, or in lieu of, notifying the user of the impending system failure, the system can be automatically de-activated to prevent data loss and/or further damage to the recording system.

  • 15-Lipoxygenase-1 activates tumor suppressor p53 independent of enzymatic activity

    Hong Zhu   Wayne Glasgow   Margaret D. George   Kali Chrysovergis   Kenneth Olden   John D. Roberts   Thomas Eling  

    15-LOX-1 and its metabolites are involved in colorectal cancer. Recently, we reported that 15-LOX-1 overexpression in HCT-116 human colorectal cancer cells inhibited cell growth by induction of p53 phosphorylation (4). To determine whether the 15-LOX-1 protein or its metabolites are responsible for phosphorylation of p53 in HCT-116 cells, we used HCT-116 cells that expressed a mutant 15-LOX-1. The mutant 15-LOX-1 enzyme, with a substitution of Leu at residue His361, was devoid of enzymatic activity. HCT-116 cells transiently transfected with either native or mutant 15-LOX-1 showed an increase in p53 phosphorylation and an increase in the expression of downstream genes. Thus, 15-LOX-1 induces p53 phosphorylation independent of enzymatic activity. Treatment of A549 human lung carcinoma cells with IL-4 increased the expression of 15-LOX-1 and also increased the expression of downstream targets of p53. This confirmed that the activation of p53 was also observed in wild-type cells expressing physiological 15-LOX-1. Immunoprecipitation experiments revealed that 15-LOX-1 interacts with, and binds to, DNA-dependent protein kinase (DNA-PK). The binding of 15-LOX-1 to DNA-PK caused an approximate 3.0-fold enhancement in kinase activity, resulting in increased p53 phosphorylation at Ser15. Knockdown of DNA-PK by small interfering RNA (siRNA) significantly reduced p53 phosphorylation. Furthermore, confocal microscopy demonstrated a colocalization of 15-LOX and DNA-PK in the cells. We propose that the 15-LOX-1 protein binds to DNA-PK, increasing its kinase activity and results in downstream activation of the tumor suppressor p53, thus revealing a new mechanism by which lipoxygenases (LOX) may influence the phenotype of tumor cells.

  • Efficient Algorithms for Finding a Longest Common Increasing Subsequence

    Wun-Tat Chan, Yong Zhang, Stanley P. Y. Fung, Deshi Ye   Hong Zhu  

    We study the problem of finding a longest common increasing subsequence (LCIS) of multiple sequences of numbers. The LCIS problem is a fundamental issue in various application areas, including the whole genome alignment and pattern recognition. In this paper we give an efficient algorithm to find the LCIS of two sequences in O(min(r logℓ, nℓ + r)loglog n + n log n) time where n is the length of each sequence and r is the total number of ordered pairs of positions at which the two sequences match and ℓ is the length of the LCIS. For m sequences where m ≥ 3, we find the LCIS in O(min(mr 2,mr log ℓlog m r) + mnlog n) time where r is the total number of m-tuples of positions at which the m sequences match. The previous results find the LCIS of two sequences in O(n 2) and O(n ℓ log n) time. Our algorithm is faster when r is relatively small, e.g., for r < min(n 2/loglogn,nℓ).

  • Fine-Grained Access Control for Database Management Systems

    Hong Zhu   Kevin Lü  

    A practical approach for developing fine-grained access control (FGAC) for database management systems is reported in this paper. We extend SQL language to support security policies. The concept of the policy type for databases is proposed. We implement the policy reuse through the use of policy types and policy instances to alleviate the administration workload of maintaining security policies. The policies for rows and columns can be expressed with policy types. Moreover, complicated database integrity constraints can also be expressed by policy types, and no further purpose-built programs are needed to create specific security control policies. We implement the fine-grained access control in a relational database management system DM5 [4]. The performance test results based on TPC-W are also presented.
