Google Reader Adds Shared Notes, Non-Feed Page Capture [Social Bookmarking]
via Lifehacker by Kevin Purdy on May 05, 2008
Google adds yet another social-ish function, "Notes," to its Reader feed-browsing tool. The practical use comes from a new bookmarklet that posts whatever page you're looking at to your shared Reader items, with your own notes attached. You can also post notes with no link at all to be shared with your "friends," making it a kind of Twitter clone for, well, avid feed readers. As one blogger...

Visible Fluorescence Spectroscopy of Single Proteins at Liquid-Helium Temperature
via Recent Articles in Phys. Rev. Lett. by Satoru Fujiyoshi, Masanori Fujiwara, and Michio Matsushita on April 21, 2008
Author(s): Satoru Fujiyoshi, Masanori Fujiwara, and Michio MatsushitaFluorescence spectroscopy of single proteins at liquid-helium temperatures reveals a relation between structural dynamics and biological functions of the proteins. The technical difficulties in detecting visible fluorescence are chromatic aberration and optical background. They were overcome by a ne...[Phys. Rev. Lett. 100,...

Reply to “Comment on ‘Self-organized criticality and absorbing states: Lessons from the Ising model’ ”
via Recent Articles in Phys. Rev. E by Gunnar Pruessner and Ole Peters on April 22, 2008
Author(s): Gunnar Pruessner and Ole PetersIn R. Dickman, M. A. Muñoz, A. Vespignani, and S. Zapperi [Braz. J. Phys. 30, 27 (2000)], Dickman suggested that self-organized criticality can be produced by coupling the activity of an absorbing state model to a dissipation mechanism and adding an external drive. We analyzed the proposed mechanis...[Phys. Rev. E 77, 048102] Published Wed Apr 23, 2008

Two-dimensional electronic structure of the adsorbate system N∕Cu(100) : Photoelectron spectroscopy and one-step model calculations
via Recent Articles in Phys. Rev. B by T. Michalke, R. Matzdorf, J. Braun, and A. Postnikov on April 22, 2008
Author(s): T. Michalke, R. Matzdorf, J. Braun, and A. PostnikovIn this paper, we present a detailed study of the electronic structure of the adsorbate system Cu(100)c(2×2)N by using angle-resolved ultraviolet photoelectron spectroscopy. The measured spectra reveal a variety of complex multipeak structures below the Fermi level. The adsorbate-derived states, wh...[Phys. Rev. B 77, 165425]...

Fast-responding nonlinear phase shifter using a signal-wave gain medium
via Recent Articles in Phys. Rev. A by K. J. Jiang, L. Deng, E. W. Hagley, and M. G. Payne on April 21, 2008
Author(s): K. J. Jiang, L. Deng, E. W. Hagley, and M. G. PayneUsing a full density matrix formalism we show that for a lifetime broadened four-level scheme with a signal wave gain medium a large nonlinear phase shift can be induced without signal wave slowdown and attenuation. In this system the signal wave acquires a large nonlinear phase shift and travels wi...[Phys. Rev. A 77, 045804]...

Structures and heats of formation of the neutral and ionic PNO, NOP, and NPO systems from electronic structure calculations
via Journal of Chemical Physics: All Topics by (author unknown) on April 23, 2008
Daniel J. Grant, David A. Dixon, Andre E. Kemeny, and Joseph S. Francisco High level ab initio electronic structure calculations using the coupled cluster CCSD(T) method with augmented correlation-consistent basis sets extrapolated to the complete basis set limit have been performed on the PNO, NOP, and NPO isomers and their corresponding anions and cations. Geometries fo ... [J. Chem. Phys....

Hidden order in crackling noise during peeling of an adhesive tape
via Recent Articles in Phys. Rev. E by Jagadish Kumar, M. Ciccotti, and G. Ananthakrishna on April 22, 2008
Author(s): Jagadish Kumar, M. Ciccotti, and G. AnanthakrishnaWe address the longstanding problem of recovering dynamical information from noisy acoustic emission signals arising from peeling of an adhesive tape subject to constant traction velocity. Using the phase space reconstruction procedure we demonstrate the deterministic chaotic dynamics by establishin...[Phys. Rev. E 77, 045202] Published...
