Falling is an important problem in the health maintenance of people above middle age. Portable accelerometer systems have been designed to detect falls. However, false alarms induced by some dynamic motions, such as walking and jumping, are difficult to avoid. Acceleration cross-product (AC)-related methods are proposed and examined by this study to seek(More)
a r t i c l e i n f o In the fast changing financial circumstances of nowadays, in avoiding the crisis of closing down, financial institutions are concerned about the efficiency and risk strictly in the meantime. Therefore, efficiency and risk management are goals for a financial institution administrator. Data Envelopment Analysis (DEA) is a non-parameter(More)
Utilizing multi-bit flip-flops (MBFFs) is one of the most effective power optimization techniques in modern nanometer integrated circuit (IC) design. Most of the previous work apply MBFFs without doing placement refinement of combinational logic cells. Such problem formulation may result in less power reduction due to tight timing constraints with fixed(More)
sunate versus quinine for treating severe malaria. Cochrane Database Syst Rev. To the Editor: Mycobacterium wolinskyi is a rapidly growing my-cobacterium that belongs to the M. smegmatis group, which includes M. smegmatis sensu stricto and 2 species described in 1999 (M. goodii and M. wolinskyi) (1). Only 9 cases of infection caused by M. wolinskyi have(More)
OBJECTIVE To investigate whether heroin can directly induce apoptosis in primary cultured cortical neurons of rat's brain. METHODS Cultured primary neurons cultures were obtained from cerebral cortex of embryo rats. After 7 days, the cells were incubated with different concentrations of heroin (purity-80%) for 24 hours. The neuronal survival was assessed(More)
In this study, we adopt a three-stage approach, DEA method, Frontier regressions, and DEA method to estimate bank efficiency based on information obtained from 29 banks in Taiwan for the period from 2002 to 2004. In the first stage, we employ super SBM (super Slacks-Based Measure) to estimate the scores relating bank efficiency including internal risk. In(More)
