Spin-Flavor Separation and Non-Fermi Liquid Behavior in the Multichannel Kondo Problem: A Large N Approach

We consider a $SU(N)\times SU(M)$ generalization of the multichannel single-impurity Kondo model which we solve analytically in the limit $N\rightarrow \infty$, $M\rightarrow\infty$, with $\gamma=M/N$ fixed. Non-Fermi liquid behavior of the single electron Green function and of the local spin and flavor susceptibilities occurs in both regimes, $N\le M$ and $N > M$, with leading critical exponents {\em identical} to those found in the conformal field theory solution for {\em all} $N$ and $M$ (with $M\ge 2$). We explain this remarkable agreement and connect it to ``spin-flavor separation", the essential feature of the non-Fermi-liquid fixed point of the multichannel Kondo problem.Comment: 14 pages, 1 Figure (Poscript file attached), Revte

A Tractable Model of Reciprocity and Fairness

We introduce a parametric model of other-regarding preferences. The income distribution and the kindness or unkindness of others' choices ('intentions') systematically affect a person's emotional state. The emotional state systematically affects the marginal rate of substitution between own and others' payoffs, and thus the person's subsequent choices. The model is applied to two sets of laboratory data: simple binary choice mini-ultimatum games, and Stackelberg duopoly games with a range of choices. The results confirm that other-regarding preferences respond to others' intentions as well as to the income distribution.

Beyond Same-Sex Marriage: Attitudes on LGBT Nondiscrimination Laws and Religious Exemptions - Finding from the 2015 American Values Atlas

Across 2015, the year that saw same-sex marriage become legal in all 50 states following the landmark Obergefell v. Hodges Supreme Court decision in June, public opinion on same-sex marriage remained remarkably stable. Based on interviews with more than 42,000 Americans conducted between May and December 2015, PRRI finds that 53% of Americans support allowing gay and lesbian people to legally marry, while 37% are opposed.In surveys conducted during May 2015, the month before the Supreme Court decision, 53% of the public on average supported same-sex marriage. Weekly tracking polls showed no significant shift in opinion as a result of the court decision, with the June average showing 55% support and the July average showing 53% support

Clergy Voices: Findings From the 2008 Mainline Protestant Clergy Voices Survey

Presents findings from a survey of mainline Protestant clergy on their political affiliations and views on social issues, government action on health care and the environment, and the separation of church and state. Includes comparisons by denomination

A Tractable Model of Reciprocity and Fairness

We introduce a parametric model of other-regarding preferences in which my emotional state determines the marginal rate of substitution between my own and others' payoffs, and thus my subsequent choices. In turn, my emotional state responds to relative status and to the kindness or unkindness of others' choices. Structural estimations of this model with six existing data sets demonstrate that other-regarding preferences depend on status, reciprocity, and perceived property rights.

Molecular Dynamics-Based Strength Estimates of Beta-Solenoid Proteins

The use of beta-solenoid proteins as functionalizable, nanoscale, self-assembling molecular building blocks may have many applications, including templating the growth of wires or higher-dimensional structures. By understanding their mechanical strengths, we can efficiently design the proteins for specific functions. We present a study of the mechanical properties of seven beta-solenoid proteins using GROMACS molecular dynamics software to produce force/torque-displacement data, implement umbrella sampling of bending/twisting trajectories, produce Potentials of Mean Force (PMFs), extract effective spring constants, and calculate rigidities for two bending and two twisting directions for each protein. We examine the differences between computing the strength values from force/torque-displacement data alone and PMF data, and show how higher precision estimates can be obtained from the former. In addition to the analysis of the methods, we report estimates for the bend/twist persistence lengths for each protein, which range from 0.5-3.4 $\mu$m. We note that beta-solenoid proteins with internal disulfide bridges do not enjoy enhanced bending or twisting strength, and that the strongest correlate with bend/twist rigidity is the number of hydrogen bonds per turn. In addition, we compute estimates of the Young's modulus ($Y$) for each protein, which range from $Y$ = 3.5 to 7.2 GPa
