We have discovered that the white dwarf PG 2329+267 is magnetic, and, assuming a centred dipole structure, has a dipole magnetic field strength of approximately 2.3 MG. This makes it one of only approximately 4 per cent of isolated white dwarfs with a detectable magnetic field. Linear Zeeman splitting, as well as quadratic Zeeman shifts, is evident in the hydrogen Balmer sequence and circular s...

Strong high-quality fiber Bragg gratings with photoinduced refractive-index modulation of more than 10-(3) were written in a Corning SMF-28 fiber, a P(2)O5-doped-core fiber and a pure-silica-core fluorine-doped-cladding fiber by third-harmonic radiation (267 nm, 150 fs and 1.2-1.8x1011 W/cm(2)) of a femtosecond Ti:sapphire laser using a phase mask. We compare the 267-nm photosensitivity respons...

We have investigated the nature and the origin of the telescopes depicted in three paintings of J. Bruegel the Elder completed between 1609 and 1618. The ”tube” that appears in the painting dated 1608-1612 represents a very early dutch spyglass, tentatively attributable to Sacharias Janssen or Lipperhey, prior to those made by Galileo, while the two instruments made of several draw-tubes which ...

twenty hospitals and more than one hundred and twenty churches in various parts of his Principality, was born on the 18th of March, 1545, at Mespelbrun, in the Spessart, about twenty-two miles from Frankfort-on-the-Maine, and died at Wiirzburg on the 13th of September, 1617, one year before the breaking out of the devastating thirty years' war. He was the last descendant of the time-honoured an...

The Society of Apothecaries is both a City livery company and an examining authority for the medical profession. Founded in 1617 by the royal apothecary Gideon de Laune leading a breakaway group from the Grocers' Company, the Society was instrumental in raising the status of apothecaries as general practitioners. Under the Apothecaries' Act (1815) the Society examined for the LSA and it now awa...

Targeting sequences on peroxisomal membrane proteins have not yet been identified. We have attempted to find such a sequence within PMP47, a protein of the methylotrophic yeast, Candida boidinii. This protein of 423 amino acids shows sequence similarity with proteins in the family of mitochondrial carrier proteins. As such, it is predicted to have six membrane-spanning domains. Protease suscept...

Murine double minute clone 2 oncoprotein (MDM2) is a key component in the regulation of the tumour suppressor p53. MDM2 mediates the ubiqutination of p53 in the capacity of an E3 ligase and targets p53 for rapid degradation by the proteasome. Stress signals which impinge on p53, leading to its activation, promote disruption of the p53-MDM2 complex, as in the case of ionizing radiation, or block...

In this paper we present a new approach to classifying radiographs, which is the first important task of the IRMA system. Given an image, we compute posterior probabilities for each image class, as this information is needed for further IRMA processing. Classification is done by using an extended version of Simard’s tangent distance within a kernel density based classifier. We propose a new dis...
