The scaling properties of cross sections for fragment production with respect to the isotopic composition of the emitting systems were studied long ago in light-ion induced reactions [1]. Recently, the isoscaling was also reported for heavy-ion reactions [2]. It is constituted by the exponential dependence of the production ratios R21 for fragments with neutron number N and proton number Z in r...

Mutations in mexR yield a multidrug resistance phenotype in nalB mutants of Pseudomonas aeruginosa as a result of derepression of the mexAB-oprM multidrug efflux operon. MexR produced by several nalB strains carried single amino acid changes that compromised MexR stability or its ability to dimerize. Changes at residues L95 and R21, however, produced a stable MexR protein capable of dimerizatio...

aim and background: poor nutritional behaviors currently are a widespread issue. poor nutritional behaviors include inability to maintain control over eating, food restriction with the purpose of influencing on weight and shape, and tendency toward overeating in response to the negative emotions. this study was conducted to review the relationship between the perceived body satisfaction, perfec...

In recent decades, gentrification has transformed American central city neighborhoods. I estimate a spatial equilibrium model to show that the rising value of high-skilled workers’ time contributes cities. increasing raises cost commuting and exogenously increases demand for locations by workers. While change in modest direct effect on cities, is substantially magnified endogenous amenity drive...

This study evaluates the effectiveness of geographic diversification in reducing housing investment risk. To characterize diversification potential, we estimate spatial correlation and integration among 401 U.S. metropolitan housing markets. The 2000s boom brought a marked uptrend in housing market integration associated with eased residential lending standards and rapid growth in private mortg...

While filtering has long been considered the primary mechanism by which markets supply lowincome housing, direct estimates of that process have been absent. This has contributed to doubts about the viability of markets and to misplaced policy. I fill this gap by estimating a “repeat income” model using 1985-2011 panel data. Real annual filtering rates are faster for rental housing (2.5 percent)...

Immigration and House Prices in the UK This article studies the effect of immigration on house prices in the UK. It finds that immigration has a negative effect on house prices and presents evidence that this negative effect is due to the mobility response of the native population. Natives respond to immigration by moving to different areas and those who leave are at the top of the wage distrib...
