In this paper we present a formalism for the calculation of electron transport through three-terminal junction devices, which have received attention due to their recently demonstrated non-linear electrical properties. The formalism, which is based on the scattering-matrix method, takes quantum interference effects fully into account. Furthermore, the formalism provides numerical stability in the

In Study 1 (N = 120), pictures of violent behavior taking place within or between ethnic groups were rated under different instructions. A strong cross-over effect was found: interracial violence was reported as relatively more threatening under the instruction that the study concerned anxiety, whereas violence among Whites was reported as more threatening under the instruction that the study conc

The RESET test for functional misspecification is generalised to cover systems of equations, and the properties of 7 versions are studied using Monte Carlo methods. The Rao F -test clearly exhibits the best performance as regards correct size, whilst the commonly used LRT (uncorrected for degrees-of-freedom), and LM and Wald tests (both corrected and uncorrected) behave badly even in single equati

1. Metabolically stabilized (phosphorothioate) human and rat NPY Y1 receptor oligodeoxynucleotides (ODNs) complimentary to the rat or human Y1 mRNA were synthesized; [sense (rY1-SODN, 5'-AATTCAACTCTGTTCTCC-3'), antisense (hY1-ASODN, 5'-CCTGGGAAAATAATGTTG-3' and rY1-ASODN, 5'-GGAGAACAGAGTTGAATT-3') and mismatches (hY1-MMODN, 5'-CCTGAGATAA-TAAGGTTG-3' and rY1-MM 5'-GTAGATCAGAGATGAAGT-3')] and used t

This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. The methods captures essential requirements of a cont

The impact of metabolic control on the development of rapidly progressive severe retinopathy was studied in 14 young type I insulin-dependent diabetes mellitus (IDDM) patients. Glycosylated hemoglobin (HbAlc) levels 45 months prior to and 12 months after the diagnosis of retinopathy were compared with HbAlc levels in 17 type I IDDM patients with no or minimal background retinopathy, matched for ag

Oxygen consumption, lactate production and tissue contents of ATP, phosphocreatine (PCr) and lactate were measured following readdition of K+ to K+-depleted rat portal veins, in order to study the energy turnover associated with Na+/K+ pumping. During incubation in K+-free medium at 37 degrees C spontaneous contractions disappeared in 10-20 min. Readdition of K+ (5.9 mM) after 40 min K+-free incub

Abstract in UndeterminedIn our modern society peoples attitudes towards animals are inconsistent, to say the least. Behind these heterogeneous attitudes there are several economic and cultural aspects. What possibilities do we have of studying relations between humans and animal, between nature and culture, in the distant past? What are our starting-points? How do we understand realities that diff

Based on the Keldysh formalism, the Boltzmann kinetic equation and the drift-diffusion equation have been derived for studying spin-polarization flow and spin accumulation under effect of the time-dependent Rashba spin-orbit interaction in a semiconductor quantum well. The time-dependent Rashba interaction is provided by time-dependent electric gates of appropriate shapes. Several examples of spin

Objective: To describe-and compare the consumption of total fish (marine foods) and the fish sub-groups - white fish, fatty fish, very fatty fish, fish products and crustacea, in participants from the European Investigation into. Cancer and Nutrition (EPIC) study. Design: Cross-sectional analysis of dietary intake using a computerised standardised 24-hour recall interview. Crude means, means and s

Do two impersonators select the same features of one target speaker? The present study is a comparative survey of two professional impersonators imitating the same target speakers. It is obvious that the impersonator has to capture many different phonetic features of the target speaker and some individual features seem to be more important for a successful voice imitation and for the listener when

With surface X-ray diffraction (SXRD) using a high-pressure reaction chamber we investigated in-situ the oxidation of the Ru(0001) model catalyst under various reaction conditions, starting from a strongly oxidizing environment to reaction conditions typical for CO oxidation. With a mixture Of O-2 and CO (stoichiometry, 2:1) the partial pressure of oxygen has to be increased to 20 mbar to form the
