Harmony and discord in endothelial calcium entry.
Letters to the Editor will be published, if suitable, as space permits. They should not exceed 1000 words (typed double-spaced) in length and may be subject to editing or abridgment. To The Editor: This letter addresses the recent report by Abdullaev et al. 1 In 2006, the seminal work of Feske and colleagues 2 identified membrane proteins that were named Orais, after the Greek keepers of Heaven...
متن کاملIncome Inequality between Chinese Regions: Newfound Harmony or Continued Discord?
This paper develops an improved test of economic convergence or divergence using time series methods. The usefulness of the method is illustrated in an analysis of the growth pattern between Chinese regions in 1952-2007. Comparing all combinations of regional pairs, the analysis yields support for economic divergence in roughly half of the cases. In the other half, we instead find that regions ...
متن کاملEscaping Prisoner's Dilemmas: From Discord to Harmony in the Landscape of 2x2 Games
Changes in payoffs can transform Prisoner's Dilemma and other social dilemmas into harmonious win-win games. Using the Robinson-Goforth topology of 2x2 games, this paper analyzes how payoff swaps turn Prisoner's Dilemma into other games, compares Prisoner's Dilemmas with other families of games, traces paths that affect the difficulty of transforming Prisoner's Dilemma and other social dilemmas...
متن کاملQuantum Discord and Maxwell’s Demons
Quantum discord was proposed as an information theoretic measure of the “quantumness” of correlations. I show that discord determines the difference between the efficiency of quantum and classical Maxwell’s demons in extracting work from collections of correlated quantum systems. Information has an energetic value: It can be converted into work. Maxwell’s demon was introduced into thermodynamic...
متن کاملGaussian quantum discord.
We extend the quantum discord to continuous variable systems and evaluate Gaussian quantum discord C(ϱ) for bipartite Gaussian states. In particular, for squeezed-thermal states, we explicitly maximize the extractable information over Gaussian measurements: C(ϱ) is minimized by a generalized measurement rather than a projective one. Almost all squeezed-thermal states have nonzero Gaussian disco...
