Determination of heavy quark non-perturbative parametersfrom spectral moments in semileptonic B decays
Moments of the hadronic invariant mass and of the lepton energy spectra in semileptonic B decays have been determined with the data recorded by the DELPHI detector at LEP. From measurements of the inclusive b-hadron semileptonic decays, and imposing constraints from other measurements on b- and c-quark masses, the first three moments of the lepton energy distribution and of the hadronic mass distr
A comprehensive survey of mutations in the OPA1 gene in patients with autosomal dominant optic atrophy
PURPOSE. To characterize the spectrum of mutations in the OPA1 gene in a large international panel of patients with autosomal dominant optic atrophy (adOA), to improve understanding of the range of functional deficits attributable to sequence variants in this gene, and to assess any genotype-phenotype correlations. METHODS. All 28 coding exons of OPA1, intron-exon splice sites, 273 bp 5' to exon 1
Search for charged Higgs bosons in e(+)e(-) collisions root s=189-202 GeV
A search for pair-produced charged Higgs bosons was performed in the high energy data collected by the DELPHI detector at LEP II at centre-of-mass energies from 189 GeV to 202 GeV. The three different final states, taunutaunu, c (s) over bar(c) over bars and c (s) over bar taunu were considered. New methods were applied to reject wrong hadronic jet pairings and for the tau identification, where a
Quasi-deformations of sl(2)(F) with base R[t, t(-1)]
In this paper we construct quasi-deformations of sl(2) (R) with the Laurent polynomials over the reals as base algebra and general vector fields for sl(2) (R) in the base of the quasi-deformation.
Flexible composites, strength, deformation, and fracture processes. 1. Reinforcement structures and tensile strength
Fiber-reinforced flexible composites are extensively used for different kinds of applications, for example, tubes, drive belts, tires, and coated fabrics. Typical for these materials are matrix materials allowing large strain deformation and reinforcement structures allowing bending. Apart from the tensile strength and limited bending stiffness, damage resistance and ductile-brittle transition cha
New Band Structures and an Unpaired Crossing in 78Kr
High-spin states in Kr-78 were studied using the Ni-58(Na-23,3p) reaction at 70 MeV and the Ni-58(Si-23,alpha 4p) reaction at 130 MeV. Prompt gamma-gamma coincidences were measured using the Pitt-FSU detector array and the GAMMASPHERE-MICROBALL array. Results from these experiments have led to 26 new excitation levels, some of which have been grouped into 3 new bands. Spins were assigned based on

Identification of a Ser/Thr cluster in the C-terminal domain of the human prostaglandin EP4-R essential for agonist-induced beta-arrestin1 recruitment that differs from the apparent principal phosphorylation site.
hEP4-R (human prostaglandin E2 receptor, subtype EP4) is a Gs-linked heterotrimeric GPCR (G-protein-coupled receptor). It undergoes agonist-induced desensitization and internalization that depend on the presence of its C-terminal domain. Desensitization and internalization of GPCRs are often linked to agonist-induced b-arrestin complex formation, which is stabilized by phosphorylation. Subsequentl
The effect of the non-ionic contrast medium iohexol on glomerular and tubular function in diabetic patients
The effect of the non-ionic contrast medium iohexol (Omnipaque) on renal function was investigated in diabetic patients with signs of peripheral ischaemia. Forty-six patients, 70 +/- 11 years (mean +/- SD) old, age at diabetes diagnosis 53 +/- 17 years, and with varying degrees of diabetic nephropathy were studied before 1, 2, and 30 days after aortobifemoral arteriography. Serum creatinine, creat
Intrinsic spectral blueshifts in rapidly rotating stars?
Spectroscopic radial velocities for several nearby open clusters suggestthat spectra of (especially earlier-type) rapidly rotating stars aresystematically blueshifted by 3 km s-1 or more, relative tothe spectra of slowly rotating ones. Comparisons with astrometricallydetermined radial motions in the Hyades suggests this to be an absoluteblueshift, relative to wavelengths naively expecte

Analysis of the effects of outdoor and accelerated ageing on the optical properties of reflector materials for solar energy applications
Lifetime tests of solar reflector materials are eligible prior to application, to prove the stability of the optical properties. In this work, six reflector materials were aged outdoors and in a climatic test chamber. The surfaces of the samples were inspected using profilometry and optical microscopy. The total and specular reflectance spectra were measured using spectrophotometry and the weighte

Colon cancer prevalence and estimation of differing care needs of colon cancer patients
BACKGROUND: Cancer prevalence-the proportion of people in a population with a diagnosis of cancer-includes groups with widely differing cancer care needs. We estimated the proportions of the prevalent colon cancer cases requiring initial care, terminal care and follow-up. PATIENTS AND METHODS: Prevalence by year since diagnosis was estimated from incidence and vital status data on 243,471 colon ca
Physical activity-key issues in treatment of childhood obesity.
Changes in physical activity with the aim of increasing energy expenditure are usually an important component of childhood obesity treatment. Physical activity also has several other aspects that are positive for the obese child's health, such as improving the metabolic profile and psychological well being. The aim of this paper is to give a short review of what we know about physical activity in
