OBJECTIVE: To study whether physical activity is associated with reduced occurrence of asymptomatic leg atherosclerosis. DESIGN: Longitudinal and cross-sectional analyses of the population-based cohort "men born in 1914". METHODS: Comparison of the systolic ankle/arm pressure index (AAI) at age 68 in groups who were sedentary, performed some activity, and performed regular physical training at 55

This paper presents a frequency-to-digital ΣΔ modulator designed in a digital 90 nm CMOS process, operating with a supply voltage of 0.2V. For a 7.5 μW power consumption, the SNR is 68.9 dB and the SNDR is 60.3 dB over a 20 Hz-20 kHz bandwidth. This work shows that the SNR/SNDR performance of this kind of ΣΔ converter can be adjusted over a wide range, while maintaining a state-of-the-art figure-o

Previous open-label clinical trials have provided proof of principle that intrastriatal transplants of fetal dopaminergic neurons can induce substantial and long-lasting functional benefits in patients with Parkinson's disease. However, in two recent NIH-sponsored double-blind trials, functional improvements were only marginal and the primary endpoints were not met. Severe off-phase dyskinesias we

Several migratory bird species show active cycles of hypertrophy and atrophy of nutritional organs and selected muscle groups. We develop a model for nutritional organs to identify the conditions under which such a pattern of structural change is optimal. Migrants may choose the size of two components of lean mass: a constant component that they carry throughout the entire migration period and a c

Eleonora's Falcon (Falco eleonorae) breeds in the Mediterranean region and is highly adapted for catching small birds on passage migration between Eurasia and their African winter quarters, which they feed their young. We studied gliding flight behavior of Eleonora's Falcon at a breeding colony located on a small island southwest of Sardinia, Italy. Gliding and soaring flight performance was measu

Lattice Hamiltonians with on-site interaction W have W = 0 solutions, that is, many-body singlet eigenstates without double occupation. In particular, W = 0 pairs give a clue to understand the pairing force in repulsive Hubbard models. These eigenstates are found in systems with high enough symmetry, like the square, hexagonal or triangular lattices. By a general theorem, we propose a systematic w

Popular Abstract in Swedish Vad säger notbilden? Notation är av central betydelse i västerländsk tonal musik. Repertoarens utsträckning över flera århundraden gör det angeläget att studera hur musikaliskt innehåll medieras genom notation. I denna studie har strategiskt utvalda musikers sätt att ta sig an noterna till tonal musik undersökts. Slutsatser har dragits beträffande notbildens funktionerAbstract Centering on notation is a characteristic of Western tonal music. The printed scores are expected to provide the necessary information on musical expression. In this study, strategically selected contemporary musicians’ ways of under-standing the printed scores are investigated. All participants are thoroughly familiar with musical practice in Western tonal tradition. The intention is to

Under de senaste tio åren har en känslig analysmetod för grundämnen utvecklats vid institutionen för kärnfysik vid LTH. Metoden kallas PIXE (Particle Induced X-ray Emisson) och medger att mycket små förekomster (109 – 1012 g) av grundämnen kanbestämmas i små prov. Metoden är snabb. Ett par minuters analys ger en samtidig bestämning av ett stort antal grundämnen. Analysmetoden används nu i ett stor

A number of screen-printed carbon electrodes (SPCEs) have been electrochemically studied revealing strong correlation between the reversibility of the Fe(CN)/Fe(CN) couple and the sensitivity for catechol at the same electrodes modified with cellobiose dehydrogenase (CDH). Pretreatment of the electrode surfaces increased both the heterogeneous ferricyanide reaction rate and the catechol sensitivit

The time course of relaxation under isometric and isotonic conditions was studied in preparations of rat portal vein which maintained regular phasic contractions in solutions with increased [K-+] and [Ca-2+]. It was found that the smooth muscle during isotonic lengthening was able to carry the afterload for a period of time which was longer than expected from the control isometric response. The di

Abstract in German Die Verkürzung der Untersuchungszeiten bei der klinischen Magnetresonanztomographie (MRT) bietet für den Patienten den Vorteil einer angenehmeren und schnelleren Untersuchung und erhöht gleichzeitig den Patientendurchsatz. Dies erfordert schnelle und robuste Aufnahmetechniken, welche beispielsweise auch bei der Aufnahme bewegter Organe oder für atemangehaltene Messungen eingeset

Cerebral dysfunction without corresponding structural pathology has been reported in brain imaging studies of violent offenders. Biochemical markers in the CSF reflect various types of CNS pathology, such as blood-brain barrier dysfunction (CSF/S albumin ratio), infectious or inflammatory processes (IgG and IgM indices), neuronal or axonal degeneration (CSF-tau protein) and synaptic de- or regener

This paper explores the technical feasibility of five Advanced Driver Assistance System (ADAS) functions to contribute to road traffic safety, to reach stated European (EU) and national road traffic safety targets. These functions - enhanced navigation, speed assistance, collision avoidance, intersection support and lane keeping - were selected from previous research as adequate substitutes for in
