People on the move: trends and prospects in District migration flows

Since the early 1970s, the states of the Tenth Federal Reserve District have experienced wide swings in economic activity and interstate migration. The swings in migration not only reflect the region's economic performance but also have important consequences for future economic activity.> Miller discusses recent trends and prospects for migration into and out of the district. He reviews trends in net migration flows and shows how they correspond with swings in district economic performance. Next, he examines the composition of migrant flows and indicates that a significant brain drain occurred from much of the district in the late 1980s. Finally, he considers the migration outlook for the district.Federal Reserve District, 10th ; Emigration and immigration

Telling Miller’s Tale: A Reply to David Yassky

A recent article by Professor David Yassky suggests that there is a segment of legal academia that dissents from the Standard model and has started to generate alternatives to the Standard Model. Denning and Reynolds critique that part of Yassky\u27s theory dismissing United States v. Miller as providing the basis for an individual rights interpretation of the Second Amendment

Theory of polyzwitterion conformations

Conformational characteristics of polyzwitterionic molecules in aqueous solutions are investigated using the variational method. Analytical relations are derived for the radius of gyration of a single polyzwitterionic chain as a function of the chain length, electrostatic interaction strength, added salt concentration, dipole moment and degree of ionization of the zwitterionic monomers. In the absence of the small ions (counterions and coions) near the polyzwitterionic chain, attractive dipole-dipole interactions are shown to induce a collapse of the polyzwitterionic chain. However, in the presence of the small ions, the radius of gyration is shown to be an interplay of the screening of the electrostatic interactions and the counterion adsorption on the zwitterionic sites. In addition to the well-known Debye-Huckel screening of the charge-charge interactions, screening of the charge-dipole and dipole-dipole interactions are found to play important roles in determining the size of the chain. Functional forms for the screened charge-dipole and dipole-dipole interaction potentials are presented. Furthermore, counterion adsorption on the zwitterionic monomers is predicted to be asymmetric depending on the nature of the added salt and the zwitterionic groups. Qualitative remarks regarding the solubility of these molecules in aqueous solutions along with the classical "anti-polyelectrolyte" effect (increase in the solubility in water with the addition of salt) are presented.Comment: To be appeared in J.

Transport in bilayer graphene near charge neutrality: Which scattering mechanisms are important?

Using the semiclassical quantum Boltzmann equation (QBE), we numerically calculate the DC transport properties of bilayer graphene near charge neutrality. We find, in contrast to prior discussions, that phonon scattering is crucial even at temperatures below 40K. Nonetheless, electron-electron scattering still dominates over phonon collisions allowing a hydrodynamic approach. We introduce a simple two-fluid hydrodynamic model of electrons and holes interacting via Coulomb drag and compare our results to the full QBE calculation. We show that the two-fluid model produces quantitatively accurate results for conductivity, thermopower, and thermal conductivity.Comment: 10 pages, 3 figure
