A 10-bit 5-MS/s successive approximation ADC cell and a 70-MS/s parallel ADC array based on this cell, designed and fabricated in a 1.2-?m CMOS process, are presented. The ADC cell was designed to have an input bandwidth of more than 35 MHz and a sampling time of 14 nS at a clock rate of 70 MHz. The parallel ADC array consists of 14 such cells which are timed in one clock cycle skew successively i

REX-ISOLDE is an experiment at ISOLDE/CERN with the aim to study the nuclear structure of neutron-rich nuclei using radioactive ion beams up to 2.2 MeV/u. The highly-efficient gamma-ray detector set-up MINIBALL will be used to explore reactions induced by Coulomb excitation or neutron transfer.

Aims: Guidelines for cardiovascular disease (CVD) prevention cite high levels of low-density lipoprotein cholesterol (LDL-C) as a major risk factor and recommend LDL-C goals for various risk groups. Lifestyle changes are advised as first-line treatment for patients with high cholesterol, and statins are recommended in high-risk patients. The From The Heart study investigated current practice for t

An account of the electronic structure of AmF3 and AmCl3 has been obtained by Complete Active Space calculations (CASSCF and CASPT2) using either a scalar Douglas-Kroll-Hess Hamiltonian or a relativistic effective core potential. It has been compared to the description obtained by density functional theory (DFT) methods combined with a quasi-relativistic ZORA approach, either in the scalar or two-

An assessment of impacts on Arctic terrestrial ecosystems has emphasized geographical variability in responses of species and ecosystems to environmental change. This variability is usually associated with north-south gradients in climate, biodiversity, vegetation zones, and ecosystem structure and function. It is clear, however, that significant east-west variability in environment, ecosystem str

The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated. The findings were assessed after four, 12 and 20 weeks with ro

Recently, Hilhorst (2000) presented a theoretical model describing a linear relationship between bulk electrical conductivity, sigma(a), and dielectric constant, K-a, in moist soil. Hilhorst (2000) found that using this linear relationship, measurements of the pore water electrical conductivity, sigma(p), can be made in a wide range of soil types without soil-specific calibrations. If accurate mea

We present new results for the inner valence levels of clusters of the three inert gases Ar, Kr and Xe based on photoelectron spectroscopy studies. The inner valence levels are compared to the localised core levels and to the delocalised outer valence levels. This comparison shows a gradual change from a relatively localised behaviour for Ar inner valence 3s, over the intermediate case of Kr inner

Purpose: Interstitial temperature mapping was used to determine the heat field within the prostate by the Coretherm. (ProstaLund, Lund, Sweden) transurethral microwave thermotherapy device. Gadolinium. enhanced magnetic resonance imaging (MRI) and histopathology were used to determine the extent and pattern of coagulation necrosis following treatment. The cell kill assessment feature of the device

In this paper, enhancement of the signal root estimation of a particular kind of real-valued two-dimensional (2-D) sinusoidal modes is considered. To its constitution, each mode corresponds to the superposition of two real-valued plane waves in a particular symmetry. The concept of partial forward-backward averaging, which is applicable for modes that are undamped in at least one dimension, is int

The condensation energy of homogeneous electron gas is calculated within the density-functional theory for superconductors. Purely electronic considerations include the exchange energy exactly and the correlation energy on a level of the random phase approximation. Singlet superconductivity is assumed, and the Coulomb interaction is studied with a model pairing potential at angular momentum up to

In this study a model based on mass transfer and sorption rate constants with physical significance is used for simulation of affinity chromatography, The simulation program has been used to perform a parametric analysis of the adsorption of lysozyme on Cibacron Blue-Sepharose CL-6B. The influence of process parameters as well as physical parameters on the chromatography process was investigated.

BACKGROUND: Tourette syndrome (TS) is a childhood-onset neuropsychiatric disorder that is characterized by both motor and phonic tics. One half to two thirds of children with TS experience a reduction or complete resolution of tic symptoms during adolescence. At least one third of adults with TS have comorbid obsessive-compulsive disorder (OCD). OBJECTIVES: To clarify the clinical course of tic an

The interpretation of ecological data has been greatly improved by bridging the gap between ecological and statistical models. The major challenge is to separate competing hypotheses concerning demography, or other ecological relationships, and environmental variability (noise). In this paper we demonstrate that this may be an arduous, if not impossible, task. It is the lack of adequate ecological

GenoMEL, comprising major familial melanoma research groups from North America, Europe, Asia, and Australia has created the largest familial melanoma sample yet available to characterize mutations in the high-risk melanoma susceptibility genes CDKN2A/alternate reading frames (ARF), which encodes p16 and p14ARF, and CDK4 and to evaluate their relationship with pancreatic cancer (PC), neural system
