On the Order of Isotopic Exchange Reactions [PDF]

open access: bronzeBulletin of the Chemical Society of Japan, 1969
Abstract The conditions for the applicability of the McKay law were studied. It was concluded that the first order kinetics no longer holds when the concentrations of intermediates cannot be disregarded when compared with those of reactants and products and when the rate determining step cannot be specified.

An ordering inequality for exchangeable random variables [PDF]

open access: bronzeAdvances in Applied Probability, 1986
Let X1, · ··, Xn be exchangeable random variables with finite variance and two sequences of constants satisfying a1≦···≦an, b1≦···≦bn. Suppose that a′1, ···, a′n is a rearrangement of a1, ···, an and that g(x) is a non-decreasing function. Then

Role of higher-order exchange interactions for skyrmion stability [PDF]

open access: yesNature Communications, 2020
“Skyrmions are spin textures with topological charge that have considerable technological potential due to their stability. In this theoretical work, the authors demonstrate the importance of previous unconsidered higher-order exchange terms to the ...

Exchange Rate Fundamentals and Order Flow [PDF]

open access: bronzeQuarterly Journal of Finance, 2007
We address whether transaction flows in foreign exchange markets convey fundamental information. Our General Equilibrium model includes fundamental information that first manifests at the micro level and is not symmetrically observed by all agents.

Orbital ordering and exchange interaction in the manganites [PDF]

open access: greenPhysical Review B, 2001
The microscopic origin of the exchange interaction in manganites is studied by solving an electronic model Hamiltonian for the Mn-O-Mn triad. It is shown that the magnetic structure of ${\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Ca}}_{x}{\mathrm{MnO}}_{3}$ is correctly described within an electronic Hamiltonian model, provided that the appropriate ...

Order Flow and Exchange Rate Dynamics [PDF]

open access: greenJournal of Political Economy, 2017
Macroeconomic models of nominal exchange rates perform poorly. The propor-tion of monthly exchange rate changes that these models can explain is essen-tially zero. This paper presents a model of a new kind. Instead of relying exclu-sively on macroeconomic determinants, the model includes a determinant from the field of microstructure?order flow.

Order flows and the exchange rate disconnect puzzle [PDF]

open access: greenJournal of International Economics, 2009
Abstract The aim of this paper is to establish the link between the high frequency dynamics of spot exchange rates and developments in the macroeconomy. To do so, I first present a theoretical model of exchange-rate determination that bridges the gap between existing microstructure and traditional models.

Reverse Exchangeability and Extreme Order Statistics [PDF]

open access: bronze, 2013
For a bivariate random vector (X,Y), symmetry conditions are presented that yield stochastic orderings among |X|, |Y|, |max(X,Y)|, and | min(X, Y)|. Partial extensions of these results for multivariate random vectors (X1,...,Xn) are also given.

Pecking Order Theory and Trade-Off Theory of Capital Structure: Evidence from Indonesian Stock Exchange

open access: goldJournal the Winners, 2012
Numerous empirical studies in the finance field have tested many theories for firms’ capital structure. The pecking order theory and the trade-off theory of capital structure is among the most influential theories of firms’ capital structure.

Incommensurate spiral order from double exchange interactions [PDF]

open access: yesPhys. Rev. Lett. 118, 027203 (2017), 2016
The double exchange model describing interactions of itinerant electrons with localized spins is usually used to explain ferromagnetism in metals. We show that for a variety of crystal lattices of different dimensionalities and for a wide range of model parameters the ferromagnetic state is unstable against a non-collinear spiral magnetic order.
