We continue our study of the stability of designer gravity theories, where one considers antide Sitter gravity coupled to certain tachyonic scalars with boundary conditions defined by a smooth function W . It has recently been argued there is a lower bound on the conserved energy in terms of the global minimum of W , if the scalar potential arises from a superpotential P and the scalar reaches ...

Wavefunctions of a heavy-light quark (Q, q̄) system described by a covariant Dirac hamiltonian are analyzed. By assuming that the confinement potential is a Lorentz scalar (S), the slope of the IsgurWise function is calculated at zero recoil point. The result obtained is ξ(1) = −0.93 ± 0.05. This means that the solutions are perfectly consistent. If relativistic corrections in the light quark wa...

A Feynman–Jensen version of the thermal variational principle is applied to hot gauge fields, Abelian as well as non–Abelian : scalar electrodynamics (without scalar self–coupling) and the gluon plasma. The perturbatively known self–energies are shown to derive by variation from a free quadratic (”Gaussian”) trial Lagrangian. Independence of the covariant gauge fixing parameter is reached (with...

Direct Volume Rendering (DVR) is commonly used to visualize scalar fields. Quality and significance of rendered images depend on the choice of appropriate transfer functions that assigns optical properties (e.g., color and opacity) to scalar values. We present a method that automatically generates a transfer function based on the topological behavior of a scalar field. Given a scalar field defi...

Summary It is common to want regress a scalar response on random function. This paper presents results that advocate local linear regression based projection as nonparametric approach this problem. Our asymptotic demonstrate functional outperforms its constant counterpart. Beyond the estimation of operator itself, also useful tool for predicting derivative operator, promising mathematical objec...

In scalar-tensor theories of gravity, the equation of state of dark energy, w, can become smaller than -1 without violating any energy condition. The value of w today is tied to the level of deviations from general relativity which, in turn, is constrained by solar system and pulsars timing experiments. The conditions on these local constraints for w to be significantly less than -1 are establi...

the base of this review is to consider the relevant role that animal factors (potential milk yield, body weight, body condition score, state of lactation, parity and fertility) play on milk performance (considering the energy balance and the rumen function across the full lactation curve of animals) and milk quality (milk protein content, milk fat content, milk lactose content, vitamins, minera...

In this work, we present results from a new formulation for determining image velocities from a time-sequence of X-ray projection images of owing uid. Starting with the conservation of mass principle, and physics of X-ray projection, we derive a motion constraint equation for projection imaging, a practical special case of which is shown to be the Horn and Schunck's optical ow constraint. We ar...

We consider $f(R)$ gravity theories in the presence of a scalar field minimally coupled to with self-interacting potential $(2+1)$-dimensions. Without specifying form function, we first obtain an exact black hole solution dressed hair charge appear function and discuss its thermodynamics. This at large distances gives hairy BTZ hole, it reduces when decouples. In pure supported by field, find s...

We present an exact formula for the β-function for the soft-breaking scalar mass in an N = 1 supersymmetric gauge theory, in the form of an operator acting on the anomalous dimension. In particular we give the exact form for the correction due to the ǫ-scalar mass, and show that it has a particularly simple form in the renormalisation scheme corresponding to the exact NSVZ gauge β-function.
