The middle reaches of the Yellow River (MRYR) are a key area for carrying out China’s vegetation restoration project. However, impact variation on runoff in MRYR is still unclear. For quantitatively evaluating contribution rate to MRYR, this paper quantified relationship between Normalized Difference Vegetation Index (NDVI) and Budyko parameters (w). Then, we used multiple linear regression cal...

BACKGROUND Heart rate can be used to prescribe exercise intensity for development and maintenance of cardiorespiratory fitness. The aim of this study was to identify the dynamics of heart rate response during moderate-to-vigorous treadmill exercise and to explore parameter dependencies with respect to time, intensity level and step-change direction. The focus was on simple approximate models fo...

Barium substituted nanocrystalline ferrites with chemical composition BaxCa1-xFe2O4 (x =0.0 to 0.25) BCAF were prepared by solution combustion method. The phase formation of mixed spinal structured ferrites was confirmed by PXRD analysis. The average crystallite size was calculated using Debye-Scherrer formula and it was found to be in the range of 27-44 nm. Surface morphology was analyzed by S...

We study equilibrium statistical mechanics of classical point counter-ions, formulated on 2D Euclidean space with logarithmic Coulomb interactions (infinite number of particles) or on the cylinder surface (finite particle numbers), in the vicinity of a single uniformly charged line (one single double layer), or between two such lines (interacting double layers). The weak-coupling Poisson-Boltzm...

We give a smooth analogue of the classical Schläfli formula, relating the variation of the volume bounded by a hypersurface moving in a general Einstein manifold and the integral of the variation of the mean curvature. We extend it to variations of the metric in a Riemannian Einstein manifold with boundary, and apply it to Einstein cone-manifolds, to isometric deformations of Euclidean hypersur...

The first law of black hole thermodynamics in the presence a cosmological constant $\mathrm{\ensuremath{\Lambda}}$ can be generalized by introducing term containing variation $\ensuremath{\delta}\mathrm{\ensuremath{\Lambda}}$. Similar to other terms law, which are variations some conserved charges like mass, entropy, angular momentum, electric charge, etc., it has been shown [Classical Quant. G...
