Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, PCN, i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and the survival of the completely fused system against fission. ...
We investigate the extension of binning methodology to fast computation of several auxiliary quantities that arise in local polynomial smoothing. Examples include degrees of freedom measures, cross-validation functions, variance estimates and exact measures of error. It is shown that the computational eeort required for such approximations is of the same order of magnitude as that required for ...
Pregnancy is perceived by many pregnant mothers as a period of happiness in anticipation of motherhood. Not all pregnant mothers experience cheerfulness as some may experience a high anxiety and depression level for unknown reasons. The purpose of this study was to determine the level of anxiety and depression among high risk pregnant women and the factors that contribute to their level of anxi...
Recent estimates in standard models of wage determination for both unionization and occupational licensing have shown wage effects that are similar across the two institutions. These cross-sectional estimates use specialized data sets, with small sample sizes, for the period 2006 to 2008. The authors’ analysis examines the impact of unions and licensing coverage on wage determination using new ...
This paper investigates project management methods used during the execution phase of new product development projects. Based on prior field observations, organizational theory and product development literature, we pose hypotheses regarding the effectiveness of the project execution methods of formality, project management autonomy and resource flexibility. A cross-sectional survey sample of 1...
This paper examines the shortand long-run dynamics among institutional capital flows and returns in private real estate markets. The main tool of analysis we employ is a vector autoregressive (VAR) regression model in which both institutional capital flows and returns are specified as endogenous variables in a two equation simultaneous system and in which we also control for various financial a...
Elastomer polydimethylsiloxane (PDMS) films with embedded in-plane gradient stress are created by making PDMS/(PDMS + silicone oil) crosslinked bilayers and extracting the oil in a suitable organic solvent bath. The collapse of the elastomer after oil extraction generates differential stress in the films that is manifested through their out-of-plane deformation. The curvature κ of narrow stripe...
Laser-Raman and infrared spectroscopic studies reveal abundant beta-pleated sheet conformation in the eggshell proteins of the fish Salmo gairdneri. This secondary structure is the underlying molecular conformation, dictating the formation of the helicoidal architecture of the eggshell. Disulphide bonds crosslink the eggshell proteins of the fertilized eggs and are apparently found in g-g-g (ga...
This paper describes the TALP-UPC participation in the WMT’13 Shared Task on Quality Estimation (QE). Our participation is reduced to task 1.2 on System Selection. We used a broad set of features (86 for German-to-English and 97 for English-to-Spanish) ranging from standard QE features to features based on pseudo-references and semantic similarity. We approached system selection by means of pai...
