Coronary heart disease beliefs and misconceptions among cardiac patients and people with chronic illness  [PDF]
Yu-Ping Lin, Tsae-Jyy Wang, Heng-Hsin Tung, Gill Furze
Open Journal of Nursing (OJN) , 2012, DOI: 10.4236/ojn.2012.21001
Abstract: What people believe about their illness may affect how they cope with it. It has been suggested that such beliefs may be commonly held within society. This cross-sectional investigation examined the cardiac beliefs and misconceptions among cardiac patients and people with chronic illness. Participants with a noncardiac chronic illness hold similar cardiac misconceptions to people with heart disease (p = 0.58). Both groups showed high agreement on “people with heart disease should take life easy” and “always avoid anything that might bring on angina”. People with chronic illness are more likely than cardiac patients to believe that “once you have has one heart attack you are bound to have another one”.
Classification and regression tree analysis in acute coronary syndrome patients  [PDF]
Heng-Hsin Tung, Chiang-Yi Chen, Kuan-Chia Lin, Nai-Kuan Chou, Jyun-Yi Lee, Daniel L. Clinciu, Ru-Yu Lien
World Journal of Cardiovascular Diseases (WJCD) , 2012, DOI: 10.4236/wjcd.2012.23030
Abstract: Objectives: The objectives of this study are to use CART (Classification and regression tree) and step-wise regression to 1) define the predictors of quality of life in ACS (acute coronary syndrome) patients, using demographics, ACS symptoms, and anxiety as independent variables; and 2) discuss and compare the results of these two statistical approaches. Back- ground: In outcome studies of ACS, CART is a good alternative approach to linear regression; however, CART is rarely used. Methods: A descriptive survey design was used with 100 samples recruited. Result and Conclusions: Anxiety is the most significant predictor and also a stronger predictor than symptoms of ACS for the quality of life. The anxiety level patients experienced at the time heart attack occurred can be used to predict quality of life a month later. Furthermore, the majority of ACS patients experienced a moderate to high level of anxiety during a heart attack.
Objective and Self-Perceived Facial Skin Status Using Whitening Efficacy of Cosmetic Products on Taiwanese Women  [PDF]
Hsin-Tung Lin, Gwo-Shing Chen, Feng-Lin Yen, Kuan-Nien Chen
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2016, DOI: 10.4236/jcdsa.2016.64015
Abstract: Background: Tranexamic acid and vitamin C derivatives are important reagent used in cosmetic skin-whitening products. Recently, self-perceptions regarding improvement in facial skin status have been increasingly recognized as an important outcome of whitening cosmetic products intervention. Aims: The purpose of the study was to determine the receptiveness of objective and self-perceived facial skin status using whitening cosmetic products. Methods: A total of 40 volunteers were photographed using the Visia? machine and completed questionnaires at pre- and post-operation (8 weeks after receiving whitening cosmetic products). Visia? digital image analysis and questionnaires were used for assessment of facial skin status. The receptiveness of objective and self-perceived measures was assessed by paired t test and Effect Size (ES). Results: There were progresses with regard to the surface spot (ES = 0.22), wrinkles (ES = 0.24), texture (ES = 0.31) and pores (ES = 0.21) after using cosmetic products with tranexamic acid. For self-perceived measures, there were significant progresses in pigmented spots (ES = 0.75), rough complexion (ES = 0.76), red complexion (ES = 0.41), wrinkle (ES = 0.58) and obvious pores (ES = 0.75). Conclusions: This study suggests that the whitening cosmetic products are associated with improvement of objective and self-perceived facial skin status. The results could be provided as available information for cosmetic investigation.
System Level Integration of Simulation Methods for High Data-Rate Transmission Circuit Design Applications
Heng-Shou Hsu;Heng-Tung Hsu
PIER , 2009, DOI: 10.2528/PIER09010402
Abstract: A system level integration of simulation methods for high data-rate transmission circuit design applications is developed in this paper. While the elementary circuit theory was responsible for designing the circuits to meet the required performance specifications, three dimensional full-wave electromagnetic simulation technique was adopted to characterize the off-chip parasitic effects induce from the packages. The developed technique was applied for the design of optical Pick-Up Head (PUH) driver circuitry and a data transmission rate up to 640Mega bits per second (Mb/s) was achieved with standard 0.35 μm CMOS technology, showing the promising feature of applying such technique in successful design for high data-rate transmission circuits.
Quantitative Protein Localization Signatures Reveal an Association between Spatial and Functional Divergences of Proteins

PLOS Computational Biology , 2014, DOI: doi/10.1371/journal.pcbi.1003504
Abstract: Protein subcellular localization is a major determinant of protein function. However, this important protein feature is often described in terms of discrete and qualitative categories of subcellular compartments, and therefore it has limited applications in quantitative protein function analyses. Here, we present Protein Localization Analysis and Search Tools (PLAST), an automated analysis framework for constructing and comparing quantitative signatures of protein subcellular localization patterns based on microscopy images. PLAST produces human-interpretable protein localization maps that quantitatively describe the similarities in the localization patterns of proteins and major subcellular compartments, without requiring manual assignment or supervised learning of these compartments. Using the budding yeast Saccharomyces cerevisiae as a model system, we show that PLAST is more accurate than existing, qualitative protein localization annotations in identifying known co-localized proteins. Furthermore, we demonstrate that PLAST can reveal protein localization-function relationships that are not obvious from these annotations. First, we identified proteins that have similar localization patterns and participate in closely-related biological processes, but do not necessarily form stable complexes with each other or localize at the same organelles. Second, we found an association between spatial and functional divergences of proteins during evolution. Surprisingly, as proteins with common ancestors evolve, they tend to develop more diverged subcellular localization patterns, but still occupy similar numbers of compartments. This suggests that divergence of protein localization might be more frequently due to the development of more specific localization patterns over ancestral compartments than the occupation of new compartments. PLAST enables systematic and quantitative analyses of protein localization-function relationships, and will be useful to elucidate protein functions and how these functions were acquired in cells from different organisms or species. A public web interface of PLAST is available at http://plast.bii.a-star.edu.sg.
Hybridization of Simulation Codes Based on Numerical High and Low Frequency Techniques for the Efficient Antenna Design in the Presence of Electrically Large and Complex Structures
Hsi-Tseng Chou;Heng-Tung Hsu
PIER , 2008, DOI: 10.2528/PIER07091104
Abstract: A hybridization approach to integrate simulation codes based on high and low frequency techniques is developed in this paper. This work allows the antenna design to be performed directly in the presence of the complex and large structures.Since the sizes of the complex structures can be extremely large electrically, and the antenna structure itself can be significantly complicated, such problems can not be resolved with a single technique alone.While low frequency techniques are generally applied for antenna design problems where small scale interactions are involved, high frequency techniques are adopted for the prediction of propagation effects inside the complex structures.The proposed hybridization approach provides a seamless integration of low and high frequency techniques that combines the advantages of both techniques in terms of accuracy and efficiency. Numerical example is presented to demonstrate the utilization of the proposed approach.
Design Rules for a Fabry-Perot Narrow Band Transmission Filter Containing a Metamaterial Negative-Index Defect
Heng-Tung Hsu;Chien-Jang Wu
PIER Letters , 2009, DOI: 10.2528/PIERL09032803
Abstract: In this work we theoretically study the optical properties of a multilayer Fabry-Perot narrow band transmission filter containing a metamaterial negative-index defect. As in the usual Fabry-Perot filter design, the negative-index defect is sandwiched by two quarter-wave dielectric mirrors. Some useful design rules on selecting value of the negative-index of the defect have been numerically elucidated. Such narrow band transmission filtering is achieved when the refractive index of defect is either a negative even integer if the thickness is taken as a quarter of design wavelength; or a negative odd integer if the thickness is taken as a half of design wavelength.
Singularities and Gauge Theory Phases II
Mboyo Esole,Shu-Heng Shao,Shing-Tung Yau
Mathematics , 2014,
Abstract: We present a simple algebraic construction of all the small resolutions for the SU(5) Weierstrass model. Each resolution corresponds to a subchamber on the Coulomb branch of the five-dimensional N=1 SU(5) gauge theory with matter fields in the fundamental and two-index antisymmetric representations. This construction unifies all previous resolutions found in the literature in a single framework.
Graph invariants from ideas in physics and number theory
An Huang,Shing-Tung Yau,Mei-Heng Yueh
Mathematics , 2014,
Abstract: We study free scalar field theory on a graph, which gives rise to a modified version of discrete Green's function on a graph studied in \cite{CY}. We show that this gives rise to a graph invariant, which is closely related to the 2-dim Weisfeiler-Lehman algorithm for graph isomorphism testing. We complement this invariant by another type of graph invariants, coming from viewing graphs as quadratic forms over the integers. We explain that the combination of these two ideas give rise to an interesting approach to the graph isomorphism problem.
Singularities and Gauge Theory Phases

Mathematics , 2014,
Abstract: Motivated by M-theory compactification on elliptic Calabi-Yau threefolds, we present a correspondence between networks of small resolutions for singular elliptic fibrations and Coulomb branches of five-dimensional N=1 gauge theories. While resolutions correspond to subchambers of the Coulomb branch, partial resolutions correspond to higher codimension loci at which the Coulomb branch intersects the Coulomb-Higgs branches. Flops between different resolutions are identified with reflections on the Coulomb branch. Physics aside, this correspondence provides an interesting link between elliptic fibrations and representation theory.
