Article history: Received 22 June 2011 Accepted 23 July 2012 Available online 31 July 2012 This study proposes a simple framework to disentangle insiders' opportunistic trade from liquidity trade. An opportunistic trade occurswhen the probability of informed trading and the speed of convergence to market efficiency increase in a month of an insider transaction. Using Thailand Securities Exchang...

Cadmium (Cd) is a highly toxic heavy metal for both plants and animals. The presence of Cd in agricultural soils is of great concern regarding its transfer in the soil-plant system. This study investigated the transfer of Cd (exogenous salts) from a wide range of Chinese soils to corn grain (Zhengdan 958). Through multiple stepwise regressions, prediction models were developed, with the combina...

This report describes an e ort to construct a National HPCC Software Exchange (NHSE). This system shows how the evolving National Information Infrastructure (NII) can be used to facilitate sharing of software and information among members of the High Performance Computing and Communications (HPCC) community. To access the system use the URL: http://www.netlib.org/nse/. Work on the National HPCC...

R elatively few studies — especially Canadian ones — have addressed the problems and issues specific to women who are injection drug users. Much of what we can say about this group of women must be extrapolated from the literature on HIV/AIDS and from reports on drug treatment programs in the US. Notwithstanding the lack of information about them, women who inject drugs are increasingly visible...

A laser trapping-microspectroscopy technique combined with excitation energy transfer from a fluorescent cationic dye (Rhodamine B, RB) to a non-fluorescent cationic dye (Malachite Green, MG) was employed to study pH effects on the diffusion coefficients of MG (D(MG)) in single cation-exchange resin microparticles with the diameters of 16 μm. When RB-pre-adsorbed resin particles were soaked in ...

The generalized Replica Exchange Method (gREM) was applied to study a solid-liquid phase transition in a nanoconfined bilayer water system using the monatomic water (mW) model. Exploiting optimally designed non-Boltzmann sampling weights with replica exchanges, gREM enables an effective sampling of configurations that are metastable or unstable in the canonical ensemble via successive unimodal ...

Effective field theory (EFT) approach, which shed new light on the methodology of nuclear physics, was used to reformulate the parity-violating (PV) nucleon-nucleon (NN) interaction recently,1 and the potential has been applied to a few two-nucleon problems.2,3 The PV two-pion-exchange (TPE) contribution to physical observables turned out to be non-negligible, but was not so significant as the ...

Many potential clinical applications of chemical exchange saturation transfer (CEST) have been studied in recent years. However, due to various limitations such as specific absorption rate guidelines and scanner hardware constraints, most of the proposed applications have yet to be translated into routine diagnostic tools. Currently, pulsed CEST which uses multiple short pulses to perform the s...

Reverse electrodialysis (RED) is a membrane-based renewable energy technology that can harvest energy from salinity gradients. The anticipated feed streams are natural river and seawater, both of which contain not only monovalent ions but also divalent ions. However, RED using feed streams containing divalent ions experiences lower power densities because of both uphill transport and increased ...
