Toward Structural Dynamics: Protein Motions Viewed by Chemical Shift Modulations and Direct Detection of C ' N Multiple-Quantum Relaxation

Multiple quantum relaxation in proteins reveals unexpected relationships between correlated or anti-correlated conformational backbone dynamics in alpha-helices or beta-sheets. The contributions of conformational exchange to the relaxation rates of C'N coh ...

DNA supercoiling and its role in DNA decatenation and unknotting

Andrzej Stasiak, Guillaume Witz

Chromosomal and plasmid DNA molecules in bacterial cells are maintained under torsional tension and are therefore supercoiled. With the exception of extreme thermophiles, supercoiling has a negative sign, which means that the torsional tension diminishes t ...

Automation of next-to-leading order computations in QCD: the FKS subtraction

We present the complete automation of the universal subtraction formalism proposed by Frixione, Kunszt, and Signer for the computation of any cross section at the next-to-leading order in QCD. Given a process, the only ingredient to be provided externally ...

Functional electric field changes in photoactivated proteins revealed by ultrafast Stark spectroscopy of the Trp residues

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Erwin Portuondo Campa, Stefan Haacke

Ultrafast transient absorption spectroscopy of wild-type bacteriorhodopsin (WT bR) and 2 tryptophan mutants (W86F and W182F) is performed with visible light excitation (pump) and UV probe. The aim is to investigate the photoinduced change in the charge dis ...

Study of B± → D*CPK ± and DCPK± decays

Tagir Aushev, Sun Hee Kim

We report a study of the modes B± → DK ± and B± → DK± where D() decays to CP eigenstates. The data sample used contains 275 × 106 BB̄ events at the Y(4S) resonance collected by the Belle detector at the KEKB energy-asymmetric e+e- collider. The CP asymme ...

A homotetrameric kinesin-5, KLP61F, bundles microtubules and antagonizes Ncd in motility assays

Henning Paul-Julius Stahlberg, Li Tao, Alex Mogilner

Background: Mitosis depends upon the cooperative action of multiple microtubule (MT)-based motors. Among these, a kinesin-5, KLP61 F, and the kinesin-14, Ncd, are proposed to generate antagonistic-sliding forces that control the spacing of the spindle pole ...

Interferometric measurements of chromatic and polarisation mode dispersion in highly birefringent single-mode fibres

Luc Thévenaz

Interferometric measurements on highly birefringent singlemode fibres have been performed. The group delay spectrum of each polarisation mode is independently measured over the whole 1-0-1-73/mi spectral range. The polarisation mode dispersion is obtained ...

RASTER ROTATION OF BILEVEL BITMAP IMAGES

Roger Hersch

A fast raster rotation algorithm based on nearest-neighbour interpolation is described. Essentially, the computation consists of two additions/subtractions and two rounding operations per rotated image pixel. The rotation time is about equal to the time ne ...
