An objective method of determining and correcting phase or position errors in numerical weather prediction is described and tested in a radar data observing system simulation experiment (OSSE) addressing the forecasting of ongoing thunderstorms. Such phase or position errors are common in numerical forecasts at grid resolutions of 1-to-20 km (meso-γ scale). It is proposed that the process of co...

Monocular visual localization and mapping algorithms are able to estimate the environment only up to scale, a degree of freedom which leads to scale drift, difficulty closing loops, and eventual failure. This paper describes an imagedriven approach for scale-drift correction which uses a convolutional neural network to infer the speed of the camera from successive monocular video frames. We obt...

In general relativistic framework of large scale structure formation theory in the universe, we investigate relation between density contrast and peculiar velocity in the Newtonian gauge. According to the gauge–invariant property of the energy–momentum tensor in the this gauge, the velocity perturbation behaves as the Newtonian peculiar velocity. In this framework, relation between peculiar vel...

In this paper we determine the one loop radiative correction to the higgs potential due to quantum fluctuations about the background metric of Randall-Sundrum model. We then examine the effects of the one loop effective potential on the stability of the classical vacuum paying particular attention to the tadpole terms which could dominate over the classical potential for small field configurati...

Betsch et al. (1) argue that our intervention failed to affect “true” vaccine skeptics’ attitudes, and that the findings of our paper (2) actually support the use of an intervention aimed at dispelling myths linking measles, mumps, and rubella (MMR) vaccines and autism. Our paper (2) focuses on analyses of 315 participants who completed the required two sessions. This sample was split into terc...

In a large region of parameter space, the tree-level hybrid inflation model is likely to be be invalidated by loop corrections. In particular, this is likely to be the case if both quartic couplings are of order unity, as is often supposed. It is likely also to be the case if there is an ultra-violet cutoff far below the Planck scale, (ΛUV ∼ < 10 GeV(V 1/4 0 /1MeV) 2/5, where V0 is the height o...

exchange rate volatility is one of the effective and ambiguous factors in agricultural product export. considering the importance of agricultural trade to avoid single-product economy, the main aim of this study was to investigate the impact of exchange rate volatility on the raisin export of iran during the years1959-2011. for this purpose, exchange rate volatility index was estimated using mo...

Lowand intermediate mass Higgs bosons decay preferably into fermion pairs. The one-loop electroweak corrections to the respective decay rates are dominated by a flavour-independent term of O(GFmt ). We calculate the two-loop gluon correction to this term. It turns out that this correction screens the leading high-mt behaviour of the one-loop result by roughly 10%. We also present the two-loop Q...

In this work, we consider a graphene-like background in braneworld scenario which is one of the interesting models in cosmology and theoretical physics. Indeed, this paper is an application of holography in condense matter. We use the geometric form of potential which help to obtain field equations and solve it to obtain the energy spectrum. In that case we calculate superpotential and energy d...
