Familial tumoral calcinosis in two Chinese patients: a case series
Che Zhang, Jiaowei Gu, Xiaoli Cheng, Kui Xiong
Journal of Medical Case Reports , 2011, DOI: 10.1186/1752-1947-5-394
Abstract: Familial tumoral calcinosis was present in two members of a Han Chinese family, namely, the son and daughter. The 14-year-old son had the first operation on his right sole of the foot at the age of six, and then experienced subsequent surgeries at a lesion in his right sole of the foot and left hip, respectively. The 16-year-old daughter underwent her first operation at the age of six in her left gluteal region, and subsequent surgeries were performed due to recurrence at the same lesion. Pathologic diagnoses of surgical specimens in both of the patients were reported as tumoral calcinosis. The laboratory results showed hyperphosphatemia with normal levels of serum calcium and alkaline phosphatase. Only surgical treatment was performed in both patients with satisfactory prognosis.This is the first report of Chinese familial tumoral calcinosis. The etiopathogenisis and treatment are discussed.Tumoral calcinosis (TC) was first described by Inclan [1] in 1943 as slow growing, progressive masses usually found adjacent to large joints such as hips, shoulders and elbows. The masses are hard and painless. Recurrence tends to be observed at the same location subsequent to inadequate resection. Further identification is based on the pathogenesis. We describe the first two cases of familial TC in Chinese siblings, and present their clinical and pathological features.A 14-year-old Han Chinese boy presented with an eight-year history of TC. He first noticed a painful mass on the bottom of his right foot at the age of six, and mass resection was performed. Then an operation was conducted for a mass that developed on the bottom of his left foot at the age of eight. A mass first occurred on his left hip at the age of 12. This mass excised and diagnosed on pathology as a tendon calcification tumor. After that, a recurrent mass on his lateral left hip was observed. On physical examination, the mass was firm, sessile, with a clear edge and normal skin temperature, and measured 4 × 5
Statistical distributions of optimal global alignment scores of random protein sequences
Hongxia Pang, Jiaowei Tang, Su-Shing Chen, Shiheng Tao
BMC Bioinformatics , 2005, DOI: 10.1186/1471-2105-6-257
Abstract: In this study, random and real but unrelated sequences prepared in six different ways were selected as reference datasets to obtain their respective statistical distributions of global alignment scores. All alignments were carried out with the Needleman-Wunsch algorithm and optimal scores were fitted to the Gumbel, normal and gamma distributions respectively. The three-parameter gamma distribution performs the best as the theoretical distribution function of global alignment scores, as it agrees perfectly well with the distribution of alignment scores. The normal distribution also agrees well with the score distribution frequencies when the shape parameter of the gamma distribution is sufficiently large, for this is the scenario when the normal distribution can be viewed as an approximation of the gamma distribution.We have shown that the optimal global alignment scores of random protein sequences fit the three-parameter gamma distribution function. This would be useful for the inference of homology between sequences whose relationship is unknown, through the evaluation of gamma distribution significance between sequences.Sequence alignment is a central problem in computational molecular biology. Every branch of molecular biology- from database search, phylogeny reconstruction to protein structure prediction- takes sequence alignments as its foundation. The functional and/or structural properties of a new sequence could be predicted from its degree of similarity with some clearly defined and known sequences. If the similarity between two sequences is statistically significant and does not simply stem from sequence repeats of low complexity, then the two sequences are likely to be homologous and thus may have similar functions and/or structures.To understand whether an observed sequence similarity implies indeed a functional or evolutionary link, or is just a chance event is the central problem for the evaluation of the statistical significance of sequence alignment
The rates and patterns of insertions, deletions and substitutions in mouse and rat inferred from introns

Chinese Science Bulletin , 2008, DOI: 10.1007/s11434-008-0352-z
Abstract: The rates and patterns of InDel (insertions and deletions) and substitution in rodent (mouse and rat) have been studied. The result reveals that deletions occur more frequently than insertions, and single nucleotide insertion and deletion are the most frequent in both mouse and rat. The frequencies of both deletions and insertions decrease rapidly with increasing InDels length, and the size distributions of both insertions and deletions can be described well by power-law. There are more AT→GC than GC → AT substitutions in the introns of rat. However, there are more GC→AT than AT→GC substitutions in the introns in mouse. The deletion bias found in introns in mouse and rat supports the prediction that intron insertions are more deleterious than deletions because of reduced transcription and splicing efficiency. The patterns of substitution suggest that both composition and GC content are not equilibrium in the introns in rodents.
A Factorial Validation of Knowledge-Sharing Motivation Construct  [PDF]
Qinxuan Gu, Yingting Gu
Journal of Service Science and Management (JSSM) , 2011, DOI: 10.4236/jssm.2011.41009
Abstract: While there is increasingly strategic importance in knowledge, it is facing new challenges to manage knowledge effectively. The paper studies the motivational construct model for knowledge sharing from the perspective of content theories and social motivation theories. The data collected by using the questionnaire survey from a variety of industries was analyzed on the basis of interviews and pretest. The results of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) showed the motivational construct model for knowledge sharing was comprised of existence motivation, relatedness motivation, growth motivation and norm motivation. The results extended the perspectives for knowledge sharing motivation and provided theoretical evidences for facilitating knowledge sharing behavior.
Multi-objective Optimization of Multi-Agent Elevator Group Control System Based on Real-time Particle Swarm Optimization Algorithm  [PDF]

Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.47048
Abstract: In order to get a globally optimized solution for the Elevator Group Control System (EGCS) scheduling problem, an algorithm with an overall optimization function is needed. In this study, Real-time Particle Swarm Optimization (RPSO) is proposed to find an optimal solution to the EGCS scheduling problem. Different traffic patterns and controller mechanisms for EGCS are analyzed. This study focuses on up-peak traffic because of its critical importance to modern office buildings. Simulation results show that EGCS based on Multi-Agent Systems (MAS) using RPSO gives good results for up-peak EGCS scheduling problem. Besides, the elevator real-time scheduling and reallocation functions are realized based on RPSO in case new information is available or the elevator becomes busy because it is unavailable or full. This study contributes a new scheduling algorithm for EGCS, and expands the application of PSO.

American Journal of Industrial and Business Management (AJIBM) , 2014, DOI: 10.4236/ajibm.2014.42016
Abstract:

Different from the market-oriented control mechanism in British and American, the guanxi-oriented control mechanism is a significant feature in Chinese family business. This paper proposes the concept of family guanxi-oriented control rights allocation for the first time. Based on the analysis about the influencing factors of the family guanxi-oriented control rights allocation, we use the sample companies coming from Zhejiang province of China to do further discussion. We find that 1) the actual controllers of Zhejiang family listed companies mainly have blood relationship; 2) parts of companies allocate the control rights between the family members who have more than three kinds of guanxi; 3) the controlling families prefer to control the board of the listed companies; 4) the intergenerational succession of control rights in Zhejiang family listed companies has been highlighted.

Open Journal of Business and Management (OJBM) , 2014, DOI: 10.4236/ojbm.2014.24037
Abstract: With the development of the family businesses, family members are coming from diversified source. Under this circumstance, guanxi and potential conflicts between family members are becoming complicated. The allocation of control rights among the family members plays an important role. This paper proposes the allocation concept of the family guanxi-oriented control rights for the first time. On the basis of the review of classical theories about the control rights allocation, it builds a theoretical analysis framework of family control rights allocation embedding guanxi.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2003, DOI: 10.4236/jmmce.2003.21003
Abstract: This paper presents the methods and techniques used in the recently developed JKMRC/FEI Mineral Liberation Analyser (MLA). The MLA system consists of a specially developed software package and a standard modern SEM fitted with an energy dispersive spectrum (EDS) analyser. The on-line program of the MLA software package controls the SEM, captures sample images, performs necessary image analysis and acquires EDS x-ray spectra unattended. Typically, 40 to 100 images (containing 4000 to 10,000 particles) are acquired for each sample block and a dozen blocks (of 30 mm in diameter) are measured overnight. The MLA off-line processing program transforms raw particle image with x-ray data into particle mineral maps and calculates bulk and liberation data from particle mineral maps.
