Contemporary Foreign Policy in Historical Perspective
When I received the invitation to address this audience on the subject of Contemporary Foreign Policy, I began to reflect on the episode, in my own experience which I thought might have some relevance to the changes we see occurring in the world today. The first thing that came to mind was a moment back in October of 1939, just after the Germans had overrun Poland. I arrived, a novice in such matters, in the city of Berlin and sought out the advice of the American military attack, a man greatly respected and honored in the American community in Berlin at the time. He was Col. Bullmoose Smith, the recognized brains of the military team in the Embassy at the time. I went in to him and asked, What is it all about
The Berlin Situation
The significant fact is that over the past two or three months of this Berlin crisis, the West has been developing an increasingly strong position from the points of view of politics and propaganda, of economics and cultural influence

Correlation entropy of synaptic input-output dynamics
The responses of synapses in the neocortex show highly stochastic and
nonlinear behavior. The microscopic dynamics underlying this behavior, and its
computational consequences during natural patterns of synaptic input, are not
explained by conventional macroscopic models of deterministic ensemble mean
dynamics. Here, we introduce the correlation entropy of the synaptic
input-output map as a measure of synaptic reliability which explicitly includes
the microscopic dynamics. Applying this to experimental data, we find that
cortical synapses show a low-dimensional chaos driven by the natural input
pattern.Comment: 7 pages, 6 Figures (7 figure files
Neutral-Donor-Bound-Exciton Complexes in ZnO Crystals
Neutral-donor–bound-exciton transitions have been observed in ZnO. The isolated neutral donors are made up of defect pair complexes. The neutral-donor nature of these pair complexes was determined from magneticfield measurements and from two-electron transitions. Excited states of the neutral-donor bound excitons were observed in the form of rotator states analogous to rotational states of the H2 molecule

Solubilization and Humanization of Paraoxonase-1
Paraoxonase-1 (PON1) is a serum protein, the activity of which is related to susceptibility to cardiovascular disease and intoxication by organophosphorus (OP) compounds. It may also be involved in innate immunity, and it is a possible lead molecule in the development of a catalytic bioscavenger of OP pesticides and nerve agents. Human PON1 expressed in E. coli is mostly found in the insoluble fraction, which motivated the engineering of soluble variants, such as G2E6, with more than 50 mutations from huPON1. We examined the effect on the solubility, activity, and stability of three sets of mutations designed to solubilize huPON1 with fewer overall changes: deletion of the N-terminal leader, polar mutations in the putative HDL binding site, and selection of the subset of residues that became more polar in going from huPON1 to G2E6. All three sets of mutations increase the solubility of huPON1; the HDL-binding mutant has the largest effect on solubility, but it also decreases the activity and stability the most. Based on the G2E6 polar mutations, we “humanized” an engineered variant of PON1 with high activity against cyclosarin (GF) and found that it was still very active against GF with much greater similarity to the human sequence
