Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: The J-Parc Ucn Taskforce, :, Tomokazu Aso, Masatoshi Futakawa, Tomiyoshi Haruyama | Summary: Discussions in the taskforce meetings in the period of Jan.-Mar. 2009 on the technical possibility of the ultracold neutron (UCN) source at the Japan Proton Accelerator Research Complex (J-PARC) is summarized. | Search Query: […]
Kavli Affiliate: Jos Zwanikken | First 5 Authors: Jos Zwanikken, René van Roij, , , | Summary: Within a modified Poisson-Boltzmann theory we study the effect of Bjerrum pairs on the typical length scale $1/bar{kappa}$ over which electric fields are screened in electrolyte solutions, taking into account a simple association-dissociation equilibrium between free ions and […]
Kavli Affiliate: Mark Schattenburg | First 5 Authors: Norbert S. Schulz, Glenn Allen, Mark W. Bautz, Claude C. Canizares, John Davis | Summary: Understanding the origins and distribution of matter in the Universe is one of the most important quests in physics and astronomy. Themes range from astro-particle physics to chemical evolution in the Galaxy […]
Kavli Affiliate: David Weitz | First 5 Authors: David Issadore, Katherine J. Humphry, Keith A. Brown, Lori Sandberg, David Weitz | Summary: We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent […]
Kavli Affiliate: Jos Zwanikken | First 5 Authors: Jos Zwanikken, Joost de Graaf, Markus Bier, René van Roij, | Summary: We calculate ion distributions near a planar oil-water interface within non-linear Poisson-Boltzmann theory, taking into account the Born self-energy of the ions in the two media. For unequal self-energies of cations and anions, a spontaneous […]
Kavli Affiliate: John Belcher | First 5 Authors: John Belcher, Carolann Koleci, , , | Summary: Animated textures can be used to visualize the spatial structure and temporal evolution of vector fields at high spatial resolution. The animation requires two time-dependent vector fields. The first of these vector fields determines the spatial structure to be […]
Kavli Affiliate: Steven Kahn | First 5 Authors: Chen Zheng, Roger W. Romani, Masao Sako, John Marriner, Bruce Bassett | Summary: This paper presents spectroscopy of supernovae discovered in the first season of the Sloan Digital Sky Survey-II Supernova Survey. This program searches for and measures multi-band light curves of supernovae in the redshift range […]
Kavli Affiliate: Darrell Schlom | First 5 Authors: Amit Kumar, R. Rai, Nikolas Podraza, Sava Denev, Mariola Ramirez | Summary: Using spectroscopic ellipsometry, the refractive index and absorption versus wavelength of the ferroelectric antiferromagnet Bismuth Ferrite, BiFeO_3 is reported. The material has a direct band-gap at 442 nm wavelength (2.81 eV). Using optical second harmonic […]
Kavli Affiliate: Tom Chang | First 5 Authors: Tom Chang, Cheng-chin Wu, , , | Summary: We describe a new method that is both physically explicable and quantitatively accurate in describing the multifractal characteristics of intermittent events based on groupings of rank-ordered fluctuations. The generic nature of such rank-ordered spectrum leads it to a natural […]
Kavli Affiliate: Martin Depken | First 5 Authors: Martin Depken, Helmut Schiessel, , , | Summary: Apart from being the gateway for all access to the eukaryotic genome, chromatin has in recent years been identified as carrying an epigenetic code regulating transcriptional activity. The detailed knowledge of this code contrasts the ignorance of the fiber […]
