Background and Objectives: Lack of physical activity is a worrying condition because it leads to major health problems such as obesity, high blood pressure and various metabolic disorders. Exercise is a lifestyle change suggested to reduce atherogenic markers in adults. Increased physical activity and fitness are clearly associated with a reduced risk of cardiovascular disease, but the optimal ...

The dependence of angular distributions of fast electrons generated in the interaction of p-polarized femtosecond laser pulses with foil targets on laser intensities is investigated. A novel fast electron beam along the front target surface is observed for high laser intensity. It is found that the electron acceleration along the target surface is more efficient than those in other directions.

In molecular dynamics and related fields one considers dynamical descriptions of complex systems in full (atomic) detail. In order to reduce the overwhelming complexity of realistic systems (high dimension, large timescale spread, limited computational resources) the projection of the full dynamics onto some reaction coordinates is examined in order to extract statistical information like free ...
