Synchronization and communication using semiconductor lasers with optoelectronic feedback
Semiconductor lasers provide an excellent opportunity for communication using chaotic waveforms. We discuss the characteristics and the synchronization of two semiconductor lasers with optoelectronic… Expand
Quinoline alkaloids and other constituents of Melicope semecarpifolia with antiplatelet aggregation activity.
Three new quinoline alkaloids, 2-acetylevolitrine,2-acetylpteleine, and semecarpifoline, along with 26 known compounds were isolated from the root bark of Melicope semecarcarpifolia, and several of these isolates were determined as exhibiting significant antiplatelet aggregation activities in vitro.

A fuzzy rule-based recognition method is proposed for recognizing 3-D arm movements involved in Taiwanese Sign Language (TSL) and its effectiveness is evaluated. Expand
Stable route-tracking synchronization between two chaotically pulsing semiconductor lasers.
Stable route-tracking synchronization is experimentally demonstrated in two semiconductor lasers with delayed optoelectronic feedback by calculation of the transverse Lyapunov exponents of the coupled system. Expand
Positive Charge at Position 549 Is Essential for Phosphatidylinositol 4,5-Bisphosphate-hydrolyzing but Not Phosphatidylinositol-hydrolyzing Activities of Human Phospholipase C δ1*

Results suggest that positive charge at position 549 of PLCδ1 protein is essential for the enzyme to recognize and catalyze the hydrolysis of PIP2 but not PI. Expand
Ketone EC50 values in the Microtox test.
For the ketones the geometry around the carbonyl group is an important determinant of toxicity as well as MW, water solubility, and octanol/water coefficient; as molecular weight increased, the EC50 values of soluble ketones decreased; as distance between twocarbonyl groups decreased so too didEC50 values.

Performance of Synchronized Chaotic Optical Communication Systems
In this numerical study, three different systems using semiconductor lasers with optical injection, optical feedback, or optoelectronic feedback, respectively are investigated and it is shown that chaotic optical communication at 10 Gb/s is feasible with high-speed semiconductor laser systems.

Spot weld failure analysis for accident reconstruction
COMPARISON OF CRUSH CHARACTERISTICS OF FRONTAL AND SIDE POLE IMPACTS
Pole impacts are not uncommon among all types of vehicle accidents. Frontal pole impacts have been studied to a greater extent than side pole impacts. Little attention has been focused on side pole… Expand
ANALYSIS OF SPEED- AND SLOPE-RELATED STABILITY OF TRUCK-TRAILER VEHICLES
The stability of articulated vehicles has been investigated for decades. Most research has focused on directional and/or braking performance and the design of an individual component of a vehicle.… Expand
