A RELEVANCE VECTOR MACHINE WITH ROUGH SET THEORY MODEL IN ANALYZING THE LIFE CYCLE OF NEW ECONOMIC FIRMS
No full text[[abstract]]The subprime mortgage crisis and subsequent financial tsunami have raised considerable concerns about financial risk management and evaluation. This is nowhere more apparent than in new economic firms (NEFs) with large economic targets and heavy R&D expenses, such as firms in the electronics industries. With its potential for extreme growth and superior profitability, the electronic industries in Taiwan have been in the financial stock market spotlight. Recently, the relevance vector machine (RVM) was reported to have considerably less computation complexity than support vector machines (SVM) models, since it uses fewer kernel functions. Another emerging technique is rough set theory (RST), which derives rules from data. Based on the corporation life cycle theory (CLC), this study developed a relevance vector machine with rough set theory (RVMRS) to predict the status of a corporation in the decline stage. To demonstrate the performance of the designed RVMRS model, the study used electronic industries data from the Taiwan Economic Journal data bank, Taiwan Security Exchange, and Securities and Futures Institute in Taiwan. Experimental results revealed that the presented RVMRS model can predict the decline stage in a firm's life cycle with satisfactory accuracy, and generate rules for investors, managers, bankers and regulators that enable them to make suitable judgments. In addition, this study proved that the transparency and information disclosure index (TDI) is crucial to predicting the financial decline of corporations.[[note]]SC

Variations of care quality for infectious pulmonary tuberculosis in Taiwan: a population based cohort study
No full textMaterial properties of anisotropic conductive films (ACFs) and their flip chip assembly reliability in NAND flash memory applications
No full textIn this paper, the material properties of anisotropic conductive films (ACFs) and ACF flip chip assembly reliability for a NAND flash memory application were investigated. Measurements were taken on the curing behaviors, the coefficient of thermal expansion (CTE), the modulus, the glass transition temperature T-g), and the die adhesion strength of six types of ACF. Furthermore, the bonding processes of the ACFs were optimized. After the ACF flip chip assemblies were fabricated with optimized bonding processes, reliability tests were then carried out. In the pressure cooker test, the ACF with the highest adhesion strength showed the best reliability and the ACF flip chip assembly revealed no delamination at the chip-ACF interface, even after 96 h. In the high temperature storage test and the thermal cycling test, the reliability of the ACF flip chip assembly strongly depends on the Tg value of the ACF. In the thermal cycling test, in particular, which gives ACF flip chip assemblies repetitive shear stress, high value of CTE above T-g accelerates the failure rate of the ACF flip chip assembly. From the reliability test results, ACFs with a high T-g and a low CTE are preferable for enhancing the thermal and thermo-mechanical reliability. In addition, a new double-sided chip package with a thickness of 570 mu m was demonstrated for NAND flash memory application. In conclusion, this study verifies the ACF feasibility, and recommends the optimum ACF material properties, for NAND flash memory application. (C) 2008 Elsevier Ltd. All rights reserved
Can models of author intention support quality assessment of content?
Full text linkAcademics seek to find, understand and critically review the work of other researchers through published scientific articles. In recent years, the volume of available information has significantly increased, partly due to technological advancements and partly due to pressures on academics to 'publish or perish'. This amount of papers presents a challenge not only for the peer-review process but also for readers, particularly inexperienced readers, to find publications of high quality. Whilst one might rely on citation or journal rankings to help guide this decision, this approach may not be completely reliable due to biased peer-review processes and the fact that the citation count of an article does not per se indicate its quality. Here, we analyse how expected author intentions in a Related Work section can be used to indicate its quality. We show that author intentions can predict the quality with reasonable accuracy and propose that similar approaches could be used in other sections to provide an overall picture of quality. This approach could be useful in supporting peer-review processes and for a reader in prioritising articles to read. © 2019 CEUR-WS. All rights reserved.Peer reviewe
Recent advances in cell-penetrating, non-peptide molecular carriers
No full textThe intracellular delivery of proteins and other bioactive molecules by employing membrane-permeable carrier peptide vectors, e.g. HIV-1 Tat, Antp-HD, and related arginine-rich peptides are well known for a number of years. Because of some real and potential problems associated with these peptide carriers, such as instability due to various endogenous peptidases, uncertain in vivo delivery efficiency, potential neurotoxicity and immunogenicity, an urgent need exists for the development of efficient, non-peptide molecular carriers. This review briefly summarizes the structural characteristics and the delivery properties of the newly developed non-peptide carriers, in particular the ones developed in the author's laboratory, together with their potential as delivery vectors for poorly bioavailable drugs including small molecules, proteins, and nucleotides.
