Owing to the loose coupling between replicas, the replica-exchange (RE) class of algorithms should be able to benefit greatly from using as many resources as available. However, the ability to effectively use multiple distributed resources to reduce the time to completion remains a challenge at many levels. Additionally, an implementation of a pleasingly distributed algorithm such as replica-ex...

Localized impurity or defect states in the insulating barrier layer separating two ferromagnetic films affect dramatically the interlayer exchange coupling (IEC), making it significantly stronger compared to perfect barriers. We demonstrate that the impurity-assisted IEC becomes antiferromagnetic if the energy of the impurity states matches the Fermi energy and that the coupling strength decrea...

This paper presents the findings of a comparative study on the performance of the initial public offerings (IPOs) of shares listed on the Hong Kong Stock Exchange (HKX), Singapore Exchange (SGX) and Bursa Malaysia (MYX). One indicator of the success of an IPO is its subscription rate, which can be used as a proxy for the level of investor confidence in the stock being offered. This paper examin...

Outcome Number of studies Odds ratio Confidence interval (95% confidence level) Reduction in Needle Sharing 6 3.22 2.17-4.77 Needle and Syringe Programs (NSPs) are interventions that provide drug preparation and injection equipment to injection drug users to decrease equipment sharing, and consequently, HIV transmission risk. Drug equipment may include needles, syringes, and other ancillary mat...

OBJECTIVES This study sought to determine whether introduction of a needle exchange program would be associated with increased crime rates. METHODS Trends in arrests were compared in program and nonprogram areas before and after introduction of a needle exchange program in Baltimore. Trends were modeled and compared via Poisson regression. RESULTS No significant differences in arrest trends...

OBJECTIVE Examine the challenges of four service delivery models (i.e., fixed, mobile, satellite and home visits) and how service delivery may impact on NEP HIV prevention efforts. METHODS Using a modified ethnographic approach, semi-structured interviews concerning policies and procedures were conducted with staff (n = 59) of NEPs (n = 15) in Ontario. An iterative, inductive analytic process...

We present NDEx 2.0, the latest release of the Network Data Exchange (NDEx) online data commons (www.ndexbio.org) and the ways in which it can be used to (i) improve the quality and abundance of biological networks relevant to the cancer research community; (ii) provide a medium for collaboration involving networks; and (iii) facilitate the review and dissemination of networks. We describe inno...

A stock market plays as a strong role in the industrialization and economic development of the country. Among the developing countries, the contribution of the capital market have lately been recognized. This paper assess the Intensifying of Stock Markets (DSE & CSE) in Bangladesh based on Dhaka Stock Exchange (DSE) & Chittagong Stock Exchange (CSE). Information collected from secondary data du...

Chemical exchange saturation transfer (CEST) imaging is sensitive to dilute labile proton and microenvironment properties such as pH and temperature, and provides vital information complementary to the conventional MRI methods. Whereas the Bloch equations coupled by exchange terms (i.e., Bloch-McConnell equations) have been utilized to quantify 2-pool CEST contrast, it is tedious to extend the ...
