During prolonged periods of high energy expenditure (EE), restricted food intake can lead to a loss of body mass. This case study describes the preexpedition support for an unsupported 3-wk crossing of the Atacama Desert in Chile. The goals were to simulate the energy requirements of walking under varying conditions and to predict energy intake and EE to evaluate whether the expected weight los...

The Lipkin model of arbitrary particle numberN is studied in terms of exact differential-operator representation of spin-operators from which we obtain the low-lying energy spectrum with the instanton method of quantum tunnelling. Our new observation is that the well-known quantum phase transition (QPT) can also occur in the finite-N model only if N is an odd number. We furthermore demonstrate ...

We consider the Born-Oppenheimer problem near conical intersection in two dimensions. For energies close to the crossing energy we describe the wave function near an isotropic crossing and show that it is related to generalized hypergeometric functions 0 F 3. This function is to a conical intersection what the Airy function is to a classical turning point. As an application we calculate the ano...

In consideration of the safety drivers, we designed a multifunctional intelligent seecurity guarantee integrated system for highway level crossing. Different from existing intersection signs on market, highway-level indicators are based use deep learning and computer vision technology to build convolutional neural network model that can accurately recognize traffic accident images jams in short...
