The IRDF2002 dosimetry cross-section data are processed into very fine energy groups and added to the detector response library for the Monte Carlo code MCBEND. The IRDF2002 covariances are processed into broad groups to form a MCBEND detector covariance library. A number of benchmark experiments are analysed using MCBEND with both IRDF2002 and IRDF90 data and the results compared. Uncertaintie...
This paper investigates the determinants of tourism inflows to Greece. The significance of the specific sector for the Greek economy varies from 15% to 20% of GDP (measured directly or indirectly respectively). Building on the existing literature, panel data estimation techniques are used, with explanatory variables including selected macroeconomic indicators and (relative) price indices. The m...
The relative γ -decay probabilities of the 162Dy to 161Dy and 162Dy to 164Dy residual nuclei, produced using light-ion-induced direct reactions, were measured as a function of excitation energy using the CACTUS array at the Oslo Cyclotron Laboratory. The external surrogate ratio method (SRM) was used to convert these relative γ -decay probabilities into the 161Dy(n,γ ) cross section in an equiv...
An independent Science Advisory Panel (The Panel) was formed to assist the Alaska Department of Environmental Conservation evaluate the effects of wastewater discharges from cruise ships in Alaskan waters. The Panel evaluated the dilution of wastewater discharges from moving cruise ships. The results of that evaluation were used in turn to evaluate possible effects on water quality. This paper ...
This paper deals with a variety of dynamic issues in the analysis of time-series– cross-section (TSCS) data. While the issues raised are more general, we focus on applications to political economy. We begin with a discussion of specification, and lay out the theoretical differences implied by the various types of time series models that have been estimated. It is shown that there is nothing per...
We examine the relation between inventory investment and the cost of capital in the time series and the cross section. We find consistent evidence that risk premiums, rather than real interest rates, are strongly negatively related to future inventory growth at the aggregate, industry, and firm levels. The effect is stronger for firms in industries that produce durables rather than nondurables,...
We show that decomposing macroeconomic risks across horizon is key to uncover a tight link between risk premia and the real economy. Exposure in four-year returns to innovations in macroeconomic growth and volatility with a matching half-life of over four years is priced in a wide variety of test assets. Shorter-term risks are not priced. Importantly, we show that long-term growth and volatilit...
The most recent release of photonuclear interaction data for Monte Carlo applications is the ENDF/B-VII library. While this current version offers several improvements over its predecessors, it does not address the observed, sometimes quite significant variance in the measured data. For instance, for U, the cross-section data in the ENDF/B-VII library is consistently larger than all measurement...
1 1 Is the ratio of flow-mediated dilation (FMD) and shear rate a statistically-sound approach to 2 normalization in cross-sectional studies on endothelial function? 3 4 Greg Atkinson, Alan M. Batterham, Mark A. Black, Nigel T. Cable, Nicola D. Hopkins, Ellen A. 5 Dawson, Dick.H.J. Thijssen, Helen Jones, Toni M. Tinken, Daniel J.

The Sentinel-1 synthetic aperture radar (SAR) allows sufficient resources for cross-pol wind speed retrievals over the ocean. In this paper, we present technical evaluation on wind retrieval from both Sentinel-1A and Sentinel-1B IW cross-pol images. Algorithms are based on the existing theoretical and empirical ones derived from the RADARSAT-2 cross-pol data. First, to better understand the Sen...
