background: gel polymers are considered as new dosimeters for determining radiotherapy dose distribution in three dimensions. objective: the ability of a new formulation of magic-f polymer gel was assessed by experimental measurement and monte carlo (mc) method for studying the effect of gold nanoparticles (gnps) in prostate dose distributions under the internal ir-192 and external 18mv radioth...

The paper by Gilbert et al. should be on the table of every politician and National Health Service (NHS) manager in the run up to the general election, when the NHS is at the hustings.

Based on a feedback adaptation scheme, the authors model the movement of a stock market index within a framework that is composed of an internal dynamic model and an adaptive filter. The output-error model is adopted as...

Artificial neural networks (ANNs) allow users to improve forecasts through pattern recognition. The purpose of this paper is to validate ANNs as a detection tool in four financial markets. This study investigates whether market inefficiencies exist using ANN as a model. It also investigates whether additional publicly available information can provide investors with a trading advantage. In fina...

This paper investigates the determinants of countries’ export performance looking in particular at the role of international product market linkages. We begin with a novel decomposition of the growth in countries’ exports into the contribution from increases in external demand and from improved internal supply-side conditions. Building on the results of this decomposition, we move on to an econ...

We contrast how Indian firms affiliated to business groups and unaffiliated firms evaluate performance and react by adjusting their internal technology search and external market search. We propose that, compared with unaffiliated firms, business group firms are more externally oriented in setting aspiration leve...
