Abstract The relationship between trade and inequality is complex, the existing literature concludes that impacts of on are ambiguous. This article addresses this ambiguity presents robust evidence effects depend economic development, when it occurred in recent decades, their various measures. It proposes a novel identification strategy to solve for endogeneity problem by using as predicted gra...

An innovative orbit determination method which makes use of gravity gradients for Low-Earth-Orbiting satellites is proposed. The measurement principle of gravity gradiometry is briefly reviewed and the sources of measurement error are analyzed. An adaptive hybrid least squares batch filter based on linearization of the orbital equation and unscented transformation of the measurement equation is...

This study explores how intangible assets affect crash risk in Indonesia as the representative of emerging markets, especially for low intellectual capital firms. We employ regression analysis to investigate effect on Indonesia. The findings suggest that firms with are more vulnerable risk. Our further investigations also find stimulate IC firms, but cannot explain high implies Indonesia’s use ...

We derive the detailed balance condition as a solution to the Hamilton-Jacobi equation in the Hořava-Lifshitz gravity. This result leads us to propose the existence of the d-dimensional quantum field theory on the future boundary of the (d + 1)dimensional Hořava-Lifshitz gravity from the viewpoint of the holographic renormalization group. We also obtain a Ricci flow equation of the boundary the...

The application of the generalized gravity model in analyzing the Bangladesh’s trade reveals that Bangladesh’s trade is positively determined by the size of the economies, per capita GNP differential of the countries involved and openness of the trading countries. Bangladesh’s exports are positively determined by the exchange rate, partner countries’ total import demand and openness of the Bang...

is derived for surface gravity waves with nearly-elliptic front, generalising the cylindrical KP equation for nearly-concentric waves. We discuss transformations between the derived equation and two existing versions of the KP equation, for nearly-plane and nearly-concentric waves. The transformations are used to construct important classes of exact solutions of the derived equation and corresp...

The evolution of scale-invariant gravity waves from the early universe is analyzed using an equation of state which smoothly interpolates between the radiation dominated era and the present matter dominated era. We find that for large wavenumbers the standard scale-invarant wavefunction for the gravity wave severely underestimates the actual size of the gravity wave. Moreover, there is a defini...

The Ostrovsky equation is a model for gravity waves propagating down a channel under the influence of Coriolis force. This equation is a modification of the famous Korteweg-de Vries equation and is also Hamiltonian. However the Ostrovsky equation is not integrable and in this contribution we prove its nonintegrability. We also study local bifurcations of its solitary waves. MSC: 35Q35, 35Q53, 3...

We derive an analytic solution for the capillary rise of liquids in a cylindrical tube or a porous medium in terms of height h as a function of time t. The implicit t(h) solution by Washburn is the basis for these calculations and the Lambert W function is used for its mathematical rearrangement. The original equation is derived out of the 1D momentum conservation equation and features viscous ...
