We have investigated the time evolution of the transient absorption spectrum of all-trans-b-carotene in a number of solvents. In all cases we observe a loss of red and a gain of blue S1 ð2A g Þ ! SN excited state absorption on a 0.3–0.4 ps time scale. To explain these observations, a model is proposed in which distorted molecules formed in S2 ð1Bu Þ relax back to the all-trans state in S1 ð2A g...

The car-following model is a basic model of microscopic traffic simulation. The complexity of car-following behavior is suggested by a large number of factors that influence car-following behavior. Moreover, as shown repeatedly in laboratory studies of human performance, humans are very adaptable and will develop new strategies for new situations. Meanwhile, human performance and the informatio...

Neuroblastoma is a childhood cancer that is fatal in almost half of patients despite intense multimodality treatment. This cancer is derived from neuroendocrine tissue located in the sympathetic nervous system. Glypican-2 (GPC2) is a cell surface heparan sulfate proteoglycan that is important for neuronal cell adhesion and neurite outgrowth. In this study, we find that GPC2 protein is highly ex...

Due to the increasing demand for traveling in public transportation systems and increasing traffic of vehicles, nowadays vehicles are getting to be intelligent to increase safety, reduce the probability of accident and also financial costs. Therefore, today, most vehicles are equipped with multiple safety control and vehicle navigation systems. In the process of developing such systems, simulat...

We propose and study a one-dimensional traffic flow cellular automaton model of high-speed vehicles with the Fukui-Ishibashi-type acceleration for all cars, and the Nagel-Schreckenberg-type (NS) stochastic delay only for cars following the trail of the car ahead. The main difference in the delay scenario between our model and the NS model is that a car with spacing ahead longer than the velocit...

Columns at the ground floor and parking garages that could be hit by a car pose significant risk to structural stability of building superstructures. Generally, these columns are not built sustain lateral impact force generated car–column collision. In this study, performance axially loaded retrofitted reinforced concrete (RC) against is evaluated using finite element (FE) simulation. The FE mo...

In this paper an H∞ controller is designed for a hydraulically actuated active suspension system of a half-modeled vehicle in a cascade feedback structure. Using the proposed structure the nonlinear behavior of actuator is reduced significantly. In the controller synthesis, a proportional controller is used in the inner loop, and a robust H∞ controller forms the outer loop. Two H∞ controllers a...
