Sinusoidal Order Estimation using Angles between Subspaces

Abstract in UndeterminedWe consider the problem of determining the order of a parametric model from a noisy signal based on the geometry of the space. More specifically, we do this using the nontrivial angles between the candidate signal subspace model and the noise subspace. The proposed principle is closely related to the subspace orthogonality property known from the MUSIC algorithm, and we stu

Organization of Bacteriochlorophylls in Individual Chlorosomes from Chlorobaculum tepidum Studied by 2-Dimensional Polarization Fluorescence Microscopy

Chlorosomes are the largest and most efficient natural light-harvesting systems and contain supramolecular assemblies of bacteriochlorophylls that are organized without proteins. Despite a recent structure determination for chlorosomes from Chlorobaculum tepidum (Ganapathy et al. Proc. Natl. Acad. Sci. U.S.A. 2009, 106, 8525), the issue of a possible large structural disorder is still discussed co

A 2-D GRO Vernier Time-to-Digital Converter with Large Input Range and Small Latency

Abstract — The proposed time-to-digital converter (TDC) arranges two Vernier gated-ring-oscillator (GRO) branches in a 2-dimension (2-D) fashion. All delay differences between X-axis phases and Y-axis phases (based on 2-D definition) can be used, rather than only the diagonal line. The large latency time inherited from Vernier structure is therefore dramatically reduced. The TDC is implemented in

A Single Nucleotide Polymorphism Associates With the Response of Muscle ATP Synthesis to Long-Term Exercise Training in Relatives of Type 2 Diabetic Humans

OBJECTIVE-Myocellular ATP synthesis (fATP) associates with insulin sensitivity in first-degree relatives of subjects with type 2 diabetes. Short-term endurance training can modify their fATP and insulin sensitivity. This study examines the effects of moderate long-term exercise using endurance or resistance training in this cohort. RESEARCH DESIGN AND METHODS-A randomized, parallel-group trial tes

Fc{gamma}RIIB Inhibits the Development of Atherosclerosis in Low-Density Lipoprotein Receptor-Deficient Mice.

The immune processes associated with atherogenesis have received considerable attention during recent years. IgG FcRs (FcgammaR) are involved in activating the immune system and in maintaining peripheral tolerance. However, the role of the inhibitory IgG receptor FcgammaRIIB in atherosclerosis has not been defined. Bone marrow cells from FcgammaRIIB-deficient mice and C57BL/6 control mice were tra

Musikupplevelser - psykologiska synpunkter

Artikeln ger en översikt över hur man med socialpsykologiska teorier kan närma sig en beskrivning av upplevelser av musik. En tentativ slutsats är att musik är en resurs för identitetsskapande där kognitiva, emotionella och sociala faktorer är aktiva.

Platelet-dependent accumulation of leukocytes in sinusoids mediates hepatocellular damage in bile duct ligation-induced cholestasis

Background:Although it is well known that extrahepatic cholestasis induces liver damage, the mechanisms are still not completely understood. The aim of the present study was to evaluate the role of platelets and P-selectin in cholestasis-induced liver injury.Experimental approach:C57BL/6 mice underwent bile duct ligation (BDL) and pretreatment with an anti-GP1balpha antibody, which depletes platel

Psychosocial consequences of false-positive mammography among women attending breast cancer screening. Assessment, prediction, and coping.

Popular Abstract in Swedish Bröstcancer är den vanligaste dödsorsaken bland cancersjuka kvinnor. Därför rekommenderas regelbundna mammografiska hälsokontroller för tidig diagnostik och snar behandling för att förbättra prognosen. I Sverige rekommenderas kontroller för kvinnor mellan 40-74 år. Mammografiska hälsokontroller medför dock även risker, såsom till exempel behov av kompletterande bröstundOne side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. Regarding long-term consequences, research findings are inconsi

Locally based research and development units as knowledge brokers and change facilitators in health and social care of older people in Sweden

This article investigates the role of locally based research and development units (R&Ds) focusing on health and social services. Nearly 300 Local R&Ds are funded by the Swedish government with the intention to facilitate knowledge transfer and development of high quality and effective health and social care organisations. Based on analyses of archival data on aims, activities and outputs

Confirmed association between neonatal phototherapy or neonatal icterus and risk of childhood asthma

We have previously demonstrated an association between neonatal phototherapy and/or neonatal icterus and risk of hospitalization for childhood asthma. This study included children who were prescribed anti-asthmatic medication on a population basis to study exposures during the foetal and neonatal period and risk of childhood asthma. The Swedish Medical Birth Register was linked to the Swedish Pres

Dysphagia in Lewy body dementia - a clinical observational study of swallowing function by videofluoroscopic examination

Background: Dysphagia, which can result in aspiration pneumonia and death, is a well-known problem in patients with dementia and Parkinson's disease. There are few studies on dysphagia in patients with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD), especially studies objectively documenting the type of swallowing dysfunction. The aim of this study was therefore to investig

Stakeholders' Opinions on a Future In-Vehicle Alcohol Detection System for Prevention of Drunk Driving

Introduction: There is a common understanding that driving under the influence of alcohol is associated with higher risk of being involved in crashes with injuries and possible fatalities as the outcome. Various countermeasures have therefore from time to time been taken by the authorities to prevent drunk driving. One of them has been the alcohol interlock. Up to now, interlocks have mainly been

Effect of a single dose of tobramycin on systemic inflammatory response-induced acute kidney injury in a 6-hour porcine model*

OBJECTIVE:: To evaluate whether the addition of tobramycin further compromises renal function in inflammatory response-induced acute kidney injury. Effective antibiotic treatment in septic shock is crucial for the outcome. The combination of aminoglycosides with different beta-lactam antibiotics offers a broad antimicrobial coverage, rapid bacterial killing, synergistic effects, and low antibiotic

The topic of this thesis is the evolutionary history of werden in German with reference to its four functions – as full verb, as copula and as auxiliary verb in combination with the past participle in the Vorgangspassiv and also in combination with the infinitive to denote future and, in some circumstances, epistemic modal events. On the basis of scrutiny of diachronic results and a discussion of

Special: Barn som far illa - Barnuppfostran utan våld - en rättighet för varje barn.

The view of children and child rearing has undergone a marked change in our country over the past 50 years. As the first country in the world, Sweden passed legislation 1979 on the prohibition of corporal punishment in the home. Many countries have followed suit, but at present, only 5,4% of the world's children have legal protection against violence and abuse. Children's rights are on the agenda,

Epitaxial InP nanowire growth from Cu seed particles

Cu-seeded epitaxial growth of vertically aligned InP nanowires is reported for the first time. The nanowires were grown at temperatures between 290 and 420 degrees C by metal-organic vapor phase epitaxy (MOVPE) from particles formed from Cu thin films. In the temperature range of 340-370 degrees C high yields of vertically aligned nanowires could be achieved. The nanowire crystal structure and the

Technology, Institutions and allocation of time in Swedish Households, 1920-1990

The modernisation of Swedish households during the twentieth century prompted a considerable productivity growth in household production. This paper examines the association between this process and the allocation of female time in Swedish urban households during the period 1920-1990. Estimates presented in the paper suggest a minimum potential time reduction for a fixed volume of routine househol
