    Abstract: Scheduling with learning effects has received lots of research attention lately. However, the multiple-agent setting with learning consideration is relatively limited. On the other hand, the actual processing time of a job under an uncontrolled learning effect will drop to zero precipitously as the number of the jobs already processed increases. This is rather absurd in reality. Based on these observations, this paper considers a single-machine two-agent scheduling problem in which the actual processing time of a job depends not only on the job's scheduled position, but also on a control parameter. The objective is to minimize the total weighted completion time of jobs from the first agent with the restriction that no tardy job is allowed for the second agent. A branch-and-bound algorithm incorporated with several dominance properties and lower bounds is proposed to derive the optimal solution for the problem. In addition, genetic algorithms (GAs) are also provided to obtain the near-optimal solution. Finally, a computational experiment is conducted to evaluate the performance of the proposed algorithms.

    Electrochemistry and spectroelectrochemistry of carboxyphenylethynyl porphyrins
    World Scientific Pub Co Pte Ltd ; 2013

    Abstract: Zinc 5-(4-carboxy-phenylethynyl)-10,20-biphenylporphines bearing various substituents on the 10,20-phenyl rings are studied for their electrochemical and spectroelectrochemical properties. Cyclic voltammetry and optically transparent thin-layer electrochemical measurements suggest that the first reductions of these porphyrins should be the reduction reaction of the carboxylic protons. For the porphyrin ring reactions, our study shows that the redox properties can be significantly affected by the alkoxyl chains on the 10,20-phenyl rings.

    Compact Scintillator Array Detector (ComSAD) for Sounding Rocket and CubeSat Missions

    Abstract: The development of CubeSats and more frequent launch chances of sounding rockets are a total game changer to the space program, and it allows us to build space instruments that are technologically feasible and affordable. Therefore, it gives us a good opportunity to build a small cosmic-ray detector which has capabilities to measure the flux, direction, and even energy of cosmic rays at an altitude above the limitation of balloon experiments, and it may open a new door for building a constellation of detectors to study cosmic-ray physics. Compact Scintillator Array Detector (ComSAD) is a funded sounding rocket mission of Taiwan’s National Space Organization. In this paper, we present the concept, design, and performance of ComSAD which is also suitable for future CubeSat missions.

    Puerarin Accelerates Peripheral Nerve Regeneration
    World Scientific Pub Co Pte Ltd ; 2011

    Abstract: This study investigates the effect of puerarin (PR) on peripheral nerve regeneration in vitro and in vivo. PR at concentrations of 1, 10, and 100 μM significantly promoted survival and outgrowth of cultured Schwann cells, as compared to the controls treated with culture medium only. in vivo study, peripheral nerve regeneration was evaluated across a 15-mm gap in the sciatic nerve of rats using a silicone rubber nerve chamber filled with PR solution. The control group chambers were filled with normal saline only. At the end of eight weeks, animals in the PR groups, especially at a concentration of 1 μM, had a significantly higher density of myelinated axons, greater evoked action potential area, and a larger nerve conductive velocity, as compared to the controls. All experimental results indicate that PR treatment promotes nerve growth and is a promising herbal medicine for recovery of regenerating peripheral nerves.

    STRESS DISTRIBUTION WITHIN THE PLANTAR APONEUROSIS DURING WALKING — A DYNAMIC FINITE ELEMENT ANALYSIS

    Abstract: Excessive and repeated loading of the plantar aponeurosis (PA) is believed to be the most likely risk factor for developing plantar fasciitis. This study provided a novel approach to investigate the biomechanical responses of the PA during the entire stance phase of gait. One healthy subject was recruited for all the experimental measurements to validate the approach in this study. A three-dimensional (3D) finite element (FE) foot model representing this individual, with emphasis on the PA as a transversely isotropic tissue, was constructed. Kinematic data of foot motions were collected during a walking trial to serve as input conditions for the model. A peak tensile force of 922 N on the PA was found during the terminal-stance phase rather than during the mid-stance phase. The maximal peak von Mises stresses in the PA from the medial to lateral regions of the foot measured 15.61, 14.98 and 11.4 MPa at 74%, 77% and 82% of the stance phase, respectively. These peak stresses all occurred near the proximal calcaneal bony insertion site of the PA and correspond closely with the location where plantar fasciitis develops. Future work should include more subjects and clinical trials before applying these findings to the treatment of plantar fasciitis.

    PRIOR TRADING OUTCOMES AND SUBSEQUENT PORTFOLIO RISKS: USING SECURITIES DEALER IN TAIWAN AS AN EXAMPLE

    Abstract: This study examines whether the investment behavior of securities dealers is consistent with the predictions of the house money and break-even effects. Using the stock portfolios, dealers hold in Taiwan from 1996 to 2013 as a sample, we test the relationship between trading gains/losses and subsequent changes in portfolio risk. The results show that only gains with low risks, not all gaining situations, cause subsequent risk preferences, and regardless of the size of the trading loss, there is not a significant change in subsequent risk. Controlling dealers’ characteristics, industry competition, and the stock market condition, the evidence shows that the house money effect on dealer behavior exists after earning low-risk profits and does not support the break-even effect. These results are qualitatively unchanged after robustness checks that primarily exclude dealer overconfidence effect and ensure that the risk-taking behavior under low risks results in a decrease in gains and thus not a rational behavior.
