Fast full-search block-matching algorithm for motion-compensated video compression

Yih-Chuan Lin, Shen-Chuan Tai
1997 IEEE Transactions on Communications  
This paper proposes a fast block-matching algorithm that uses three fast matching error measures, besides the conventional mean-absolute error (MAE) or mean-square error (MSE). An incoming reference block in the current frame is compared to candidate blocks within the search window using multiple matching criteria. These three fast matching error measures are established on the integral projections, having the advantages of being good block features and having simple complexity in measuring

The time-consuming computations of MSE or MAE are performed on only a few candidate blocks that first pass all three fast matching criteria. Simulation results show that a reduction of over 86% in computations is achieved after integrating the three fast matching criteria into the full-search algorithm, while ensuring optimal accuracy.

An improved algorithm for the maximum agreement subtree problem

Chuan-Min Lee, Ling-Ju Hung, Maw-Shang Chang, Chia-Ben Shen, Chuan-Yi Tang
2005 Information Processing Letters  
In this paper, we solve the maximum agreement subtree problem for a set T of k rooted leaf-labeled evolutionary trees on n leaves where T contains a binary tree. We show that the O(kn 3 )-time dynamic-programming algorithm proposed by Bryant [Building trees, hunting for trees, and comparing trees: theory and methods in phylogenetic analysis, Ph.D. thesis, Dept. Math., University of Canterbury, 1997, pp. 174-182] can be implemented in O(kn 2 +n 2 log k−2 n log log n) and O(kn 3−1/(k−1) ) time by

[Scaling and related techniques for geometry problems, in: Proc. 16th Annual ACM Symp. on Theory of Computing, 1984, pp. 135-143] and Bentley [Multidimensional binary search trees in database applications, IEEE Trans. Softw. Eng. SE-5 (4) (1979) 333-340], respectively. When k < 2 + (log n − log log log n)/(log log n), the first implementation will be significantly faster than Bryant's algorithm. For k = 3, it yields the best known algorithm which runs in O(n 2 log n log log n)-time.

A Multi-parameter Persistence Framework for Mathematical Morphology [article]

Yu-Min Chung, Sarah Day, Chuan-Shen Hu
2021 arXiv   pre-print
The field of mathematical morphology offers well-studied techniques for image processing. In this work, we view morphological operations through the lens of persistent homology, a tool at the heart of the field of topological data analysis. We demonstrate that morphological operations naturally form a multiparameter filtration and that persistent homology can then be used to extract information about both topology and geometry in the images as well as to automate methods for optimizing the

Asymptotics of torus equivariant Szegő kernel on a compact CR manifold [article]

Wei-Chuan Shen
2019 arXiv   pre-print
For a compact CR manifold (X,T^1,0X) of dimension 2n+1, n≥ 2, admitting a S^1× T^d action, if the lattice point (-p_1,...,-p_d)∈Z^d is a regular value of the associate CR moment map μ, then we establish the asymptotic expansion of the torus equivariant Szegő kernel Π^(0)_m,mp_1,...,mp_d(x,y) as m→ +∞ under certain assumptions of the positivity of Levi form and the torus action on Y:=μ^-1(-p_1,...,-p_d).

Genetics of osteoporotic fracture

Shen, Chuan Qiu, Hong-Wen Deng
2011 Orthopedic Research and Reviews  
Osteoporosis is a major public health problem that results in a massive burden to patients and society through associated low-trauma, osteoporotic fractures. Previous studies have shown that osteoporosis-associated traits, such as low bone mineral density, as well as the probability of actually experiencing an osteoporotic fracture, are under strong genetic control. Susceptibility to osteoporosis and osteoporotic fractures is likely to be controlled by multiple genetic and environmental

Although numerous genetic studies, mainly candidate gene association studies, have attempted to decipher the genetic basis for osteoporosis and osteoporotic fractures, little success has been achieved. Recent advances in high-throughput genotyping technology and knowledge of common human genetic variants have shifted the approach for studying human complex disorders from candidate gene studies to large-scale genome-wide association studies. In the past three years, more than 10 genome-wide association studies have been carried out for osteoporosis. A number of genes that are associated with osteoporosis-related traits, and/or with the probability of actually experiencing an osteoporotic fracture, have been successfully identified and replicated through these studies. In this article, we review the recent progress in the genetics of osteoporosis, with an emphasis on studies that have focused on genes that directly affect osteoporotic fractures.

2020 BMC Cancer  
Tumor microenvironment (TME) plays an important role in malignant tumors. Our study aimed to investigate the effect of the TME and related genes in osteosarcoma patients. Gene expression profiles and clinical data of osteosarcoma patients were downloaded from the TARGET dataset. ESTIMATE algorithm was used to quantify the immune score. Then, the association between immune score and prognosis was studied. Afterward, a differential analysis was performed based on the high- and low-immune scores

Two datasets obtained from the GEO database were used to validate signatures. Eighty-five patients were included in our research. The survival analysis indicated that patients with higher immune score have a favorable OS and DFS. Moreover, 769 genes were determined as TME-related genes. The unsupervised clustering analysis revealed two clusters were significantly related to immune score and T cells CD4 memory fraction. In addition, two signatures were generated based on three and two TME-related genes, respectively. Both two signatures can significantly divide patients into low- and high-risk groups and were validated in two GEO datasets. Afterward, the risk score and metastatic status were identified as independent prognostic factors for both OS and DFS and two nomograms were generated. The C-indexes of OS nomogram and DFS nomogram were 0.791 and 0.711, respectively. TME was associated with the prognosis of osteosarcoma patients. Prognostic models based on TME-related genes can effectively predict OS and DFS of osteosarcoma patients.

Computational Epigenetics: the new scientific paradigm

Shen Jean Lim, Tin Wee Tan, Joo Chuan Tong
2010 Bioinformation  
Epigenetics has recently emerged as a critical field for studying how non-gene factors can influence the traits and functions of an organism. At the core of this new wave of research is the use of computational tools that play critical roles not only in directing the selection of key experiments, but also in formulating new testable hypotheses through detailed analysis of complex genomic information that is not achievable using traditional approaches alone. Epigenomics, which combines

This article examines existing computational strategies for the study of epigenetic factors. The most important databases and bioinformatic tools in this rapidly growing field have been reviewed. Background: Decoding the genomes of human and other model organisms have produced increasingly large volumes of data relevant for understanding natural selection, development and evolution, the causation of disease, and the interplay between genotypes and phenotypes during development. Collectively, this information reflects the current state of knowledge on the genetic and genome attributes of organisms. The huge amount of accumulated data represents a goldmine for the study of molecular evolution [1],[2], disease-specific mutations [3], [4], [5] and biodiversity measurements [6], [7]. While much progress has been made in genomic research, increasing evidence have shown that the study of gene factors by itself is insufficient in explaining all aspects of heritable changes in phenotype, gene function or gene expression. It is now known that chemical modifications of DNA and histones can modify gene activity through alterations in chromatin structure that blocks or promotes transcriptional initiation [8]. Enzymes involved in this process include DNA methyltransferases, histone deacetylases, histone acetylases, histone methyltransferases and the methyl-binding domain protein MECP2 [9]. Data sources for Epigenetic research: Large amount of data relevant for epigenetic research are available in scientific literature, molecular databases and case reports. Scientific literature serves as the primary source of data, providing high-level descriptions of biological entities and processes. As of January 2009, PubMed contained over 288,000 records related to epigenetic research. This information exists in the form of unstructured free text that makes the extraction of biologically meaningful information difficult.
