First-order exchange approximation
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1963It is shown that when the Born approximation is applied to rearrangement collisions in the customary way, terms of the first order in the interaction energy between the colliding particles are omitted from the exchange scattering amplitude.

The Heisenberg ferromagnet with higher-order exchange [PDF]
Journal of Physics C: Solid State Physics, 1979 The authors investigate the properties of ferromagnetic spin systems with higher-order exchange interactions, in particular with four-spin terms of the form (Si.Sj)(Sk.Sl) and (Si.Sj)(Sj.Sk). Using the Green function equation of motion method, and simple decoupling approximations, they obtain renormalised spin-wave energies, magnetisation curves, and ...

Order Exchange Key in Data Encryption
, 2012This Paper presents a new data encryption conception and algorithm. Generally the method of encryption is fixed and different key gets different encryption result. In this paper, one general data encryption key DK is used, and from the DK key we can get another key MK which is used to change the encryption method.

Working Orders in Limit-Order Markets and Floor Exchanges [PDF]
SSRN Electronic Journal, 2005 ABSTRACTWe analyze limit order markets and floor exchanges, assuming an informed trader and discretionary liquidity traders use market orders and can either submit block orders or work their demands as a series of small orders. By working their demands, large market order traders pool with small traders.

Exchange Competition and Order Splitting [PDF]
SSRN Electronic Journal, 2016 The emergence of new trading platforms has intensified order fragmentation. Yet, little is known on how this phenomenon affects the behavior of profit maximizing exchanges. I show that fragmentation may allow competing exchanges to retain market power. When order splitting is beneficial for traders, competing exchanges are complements.

Order flow and exchange rate comovement [PDF]
Journal of International Money and Finance, 2017 Abstract This paper extends the literature on the linkage between order flows and exchange rates from the univariate to the multivariate framework. We examine how order flow differentials drive exchange rate comovements using data on five major exchange rates and at three different intraday frequencies.

Order Flows, News, and Exchange Rate Volatility [PDF]
SSRN Electronic Journal, 2007 Abstract This paper examines the roles of order flow (reflecting private information) and news (reflecting public information) in explaining exchange rate volatility. Analyzing four months of a bank's high frequency dollar/euro trading, three different kinds of order flow are used in addition to seasonal patterns in explaining volatility.
