Psychological and physiological markers have been used to maximize competitive sport preparation. The aim of the present study was to evaluate the effects of two months of training and competitions on mood states and salivary cortisol diurnal variation in 15 female elite water polo players. The results demonstrated that the β coefficient values of the regression slope of cortisol values on samp...

This paper continues our investigations into the passivity-based control of the compass gait biped. It was shown in [14] for the compass gait biped, and in [15] for the general case, that a passive limit cycle for a given constant slope can be made slope invariant via potential energy shaping control. In this paper we consider the application of total energy shaping to this problem. Using a con...

In the color dipole gBFKL dynamics, we predict a strikingly different Q 2 and energy dependence of the diffraction slope for the elastic production of ground state V (1S) and radially excited V ′ (2S) light vector mesons. The color dipole model predictions for the diffraction slope for ρ 0 and φ 0 production are in a good agreement with the data from the fixed target and collider HERA experimen...

Changes of land use/land cover have a significant impact on runoff by altering the surface evaporation, soil moisture conditions and the amount of trapped ground cover, which directly impact the sustainable development of the watershed ecology. In this paper, based on remote sensing images, we simulate runoff of land-use changes of different slopes using GIS technology and SWAT model in Erhai w...

In this paper, stabilizing control of tracked unmanned ground vehicle in 3-D space was presented. Firstly, models of major modules of tracked UGV were established. Next, to reveal the mechanism of disturbances applied on the UGV, two kinds of representative disturbances (slope and general disturbances in yaw motion) were discussed in depth. Consequently, an attempting PID method was employed to...

This paper presents the gait generation and mechanical design of a humanoid robot based on a limit cycle walking method-Virtual Slope Control. This method is inspired by Passive Dynamic Walking. By shortening the swing leg, the robot walking on level ground can be considered as on a virtual slope. Parallel double crank mechanisms and elastic feet are introduced to the 5 DoF robot leg, to make t...

Ground water and surface water create a range of problems in lignite mining utilizing surface mining methods. In order to create a safe and economic mining environment, it is essential to carry out mining after dewatering the rock mass surrounding the lignite mines by advance dewatering techniques. This paper briefly describes the ground water regimes including pressure gradients associated wit...

We show that linear Regge trajectories for mesons and baryons, and the cubic mass spectrum associated with them, determine expressions for the hadron masses in terms of the universal Regge slope α ′ alone. The ground state hadron masses as calculated from these expressions are in excellent agreement with experiment for α ′ = 0.85 GeV −2 .

We are conducting a systematic lensing survey of X-ray luminous galaxy clusters at z ∼ 0.2 using the Hubble Space Telescope (HST) and large ground-based telescopes. We summarize initial results from our survey, including a measurement of the inner slope of the mass profile of A 383, and a search for gravitationally lensed Extremely Red Objects.
