Light-driven transcription, replication and enzyme catalysis are critically dependent upon a delicate transfer between molecular and supramolecular chirality. Chemists have well realized the impressive stereospecificity over many thermally accessible cycloaddition with chiral catalysts, but making light work in the enantiomer control of diarylethene photocyclization has proved to be more challe...

We have previously reported that the addition of para-phenylenediamine (PPD) to the glycerol used for mounting preparations stained for immunofluorescence with FITC conjugates results in a marked retardation of the fading that occurs during fluorescence microscopy. Studies of the kinetics of this photo-bleaching performed by microfluorimetry and on FITC conjugate in solution and the effects of ...

While several databases with Raman spectra of interest to silver corrosion have been published already, we present a catalogue of Raman spectra of silver compounds, which can be found on corroded silver and silver alloy objects, i.e. not only concerning archaeological and artistic works but all kind of silver items exposed to the atmosphere. The collected Raman spectra of these highly pure (>99...

I discuss general unified formulas for resumming collinear and soft contributions to QCD hard scattering cross sections at large x. Expansions of the resummed cross sections to next-to-next-to-next-to-leading order are also shown along with applications of the formalism. Presented at DPF 2004, Riverside, California, August 26-31, 2004.

An open edge of a simple polygon is the set of points in the relative interior of an edge. We revisit several art gallery problems, previously considered for closed edge guards, using open edge guards. A guard edge of a polygon is an edge that sees every point inside the polygon. We show that every simple non-starshaped polygon admits at most one open guard edge, and give a simple new proof tha...

The 64-channel Multianode Photo Multiplier has been evaluated as a possible choice for the photo detectors of the LHCb Ring Imaging Cherenkov detector. Contributed to the Proceedings of the 30 International Conference on High Energy Physics, 7/27/2000—8/2/2000, Osaka, Japan

abstract various studies carried out on different photo anthropometry, but each one had some deficiencies which during the years they have been resolved. the objective of this paper is to test the efficiency of two-dimensional image processing software in photo anthropometry of hand. in this applied research, 204 office workers and industrial workers were selected. their hands were measured by ...

1. INTRODUCTION. The premise of this article—what our friends in theatre would call its " conceit " —is that we are about to visit a gallery devoted to the history of calculus. Admittedly no such institution exists, but it is easily imagined. One need only think of an art museum, albeit one whose masterpieces are not canvases but theorems and whose masters are not Courbet and Cezanne but Leibni...
