PID controller design is considered where optimal controllerparametersare found with constraint on maximum sensitivity and robustness withregard to a cone bounded static nonlinearity acting in feedback withpart of the plant. Thedesign procedure has been successfully applied in the synthesis of acontroller for an Anti-lock Braking System (ABS).

The intrinsic spin Hall effect on spin accumulation and electric conductance in a diffusive regime of a 2D electron gas has been studied for a 2D strip of a finite width. It is shown that the spin polarization near the flanks of the strip, as well as the electric current in the longitudinal direction, exhibit damped oscillations as a function of the width and strength of the Dresselhaus spin-orbit

Software packages are widely used for quantification of myocardial perfusion defects. The quantification is used to assist the physician in his/her interpretation of the study. The purpose of this study was to compare the quantification of reversible perfusion defects by three different commercially available software packages. We included 50 consecutive patients who underwent myocardial perfusion

In the era of genome-wide association studies, familial risks are used to estimate disease heritability and success in gene identification. We wanted to estimate associations between type 1 diabetes mellitus and 33 autoimmune and related diseases in parents, offspring, singleton siblings and twins. The availability of a Multigeneration Register in Sweden provides reliable access to families throug

A diffusion flame of dimethyl ether (DME) and air in a counterflow burner has been investigated experimentally by means of different laser-based methods. Quantitative measurements of temperature, O-2 concentration, and OH concentration have been carried out using dual broadband rotational coherent anti-Stokes Raman Spectroscopy (CARS), Rayleigh scattering and laser-induced fluorescence (LIF). Furt

Background. No studies have been found regarding beliefs about health and illness in patients with diabetic foot ulcers investigated from a patient perspective. Beliefs might affect self-care and health. Aim. To explore beliefs about health and illness among patients with severe diabetic foot lesions that might affect self-care practice and care-seeking behaviour. Method. The study design was ex

A human tumor xenograft (L56Br-X1) was established from a breast cancer axillary lymph node metastasis of a 53-year-old woman with a BRCA1 germ-line nonsense mutation (1806C>T; Q563X), and a cell line (L56Br-C1) was subsequently derived from the xenograft. The xenograft carries only the mutant BRCA1 allele and expresses mutant BRCA1 mRNA but no BRCA1 protein as determined by immunoprecipitation or

Three species of Candelariella in western North America, characterized by biatorine apothecia, are treated. Two new species are described, C. biatorina and C. lichenicola. Candelariella biatorina is a corticolous species growing in montane conifer forests in western North America. Candelariella lichenicola, described from northwestern Mexico, is a lichenicolous fungus that lacks an independent tha

Social insects have evolved remarkable physiological adaptations and behavioural strategies that enable them to access new temporal foraging niches (for example [1]). Here we report striking correlations between the timing of foraging bouts and the modification of eye structure in four species of ants belonging to the primitive genus Myrmecia. Most noteworthy, photoreceptor diameters progressively

Muscle activity of isolated muscle strips from the middle pharyngeal constrictor, the inferior pharyngeal constrictor, the cricopharyngeal muscle, and the cervical esophagus of the rabbit was studied in organ baths in response to drugs and electrical field stimulation. These muscles of the pharyngoesophageal segment seem to lack an autonomic adrenergic and cholinergic innervation, as determined by

An efficient adaptive optics (AO) simulation code was developed, which enables first-order simulations of extremely high-order systems. The Monte-Carlo-type code employs a sparse conjugate gradient algorithm for wavefront reconstruction, and a separation of spatial frequencies into two domains to economize on the number crunching. High-order multi-conjugate adaptive optics (MCAO) systems are there

P>The coordination of swallowing and respiration is essential for a safe swallow. Swallowing consists of several subsecond events. To study this, it is important to use modalities with high temporal resolution. In this study, we have examined young healthy individuals with simultaneous videofluoroscopy, videomanometry and respiratory recording, all with high temporal resolution. The onset of 13 pr

INTRODUCTION: Analogues of vitamin A have been shown to influence growth of malignant tissue, such as pancreatic cancer. AIMS: To study the expression of retinoic acid receptors (RAR) in pancreatic cancer cells and the effect of three different retinoids on the cell number in vitro were studied. METHODOLOGY: Cell lines were established from 13 patients who underwent surgery for pancreatic adenocar

A novel approach for boosting antimicrobial peptides through end tagging with hydrophobic oligopeptide stretches is demonstrated. Focusing on two peptides derived from kininogen, GKHKNKGKKNGKHNGWK (GKH17) and HKHGHGHGKHKNKGKKN (HKH17), tagging resulted in enhanced killing of Gram-positive Staphylococcus aureus, Gram-negative Escherichia coli, and fungal Candida albicans. Microbicidal potency incre

The present study had two aims: (1) to investigate potential differences in proportion of myosin heavy chain isoforms in the trapezius muscle between female cleaners with and without trapezius myalgia and healthy teachers, and (2) to elucidate if myosin heavy chain composition and surface electromyogram (EMG) during an isokinetic endurance test of shoulder flexors are significantly related. The su

We report here on the discovery of laser action in the range 0.9-2 μm in several spectral lines of Fe II, which are associated with transitions from "pseudo-metastable" states populated by spontaneous transitions from Lyα pumped Fe II levels. The intense Lyα radiation is formed in the HII region of gas condensations close to the star η Car. The laser transitions form together with spontaneous tran

Aims: To explore the incidence, severity, time course, and risk factors of clinically significant hyponatremia in desmopressin treatment for nocturia. Methods: Data from three multi-center phase 111 trials were pooled. Hyponatremia was categorised as borderline (134-130 mmol/L) or significant (= 65 years of age) with a baseline serum sodium concentration below normal range were at high risk (75%).
