A fully integrated 0.6 V VCO for the GPS L1 band is realized in a 90 nm RF-CMOS process. The purpose of the design is to demonstrate how suitable deep submicron CMOS transistors are for ultra low voltage, low power oscillator design. The VCO operates at 6.3 GHz and a divide-by-four circuit buffer provide the wanted 1575.42 MHz signal. Measured phase noise is for a 0.6 V supply voltage and bias cur
Objectives: This study aimed to assess how transfers of clinical prediction models for early trauma care between different care contexts within a single health system affected mistriage rates. Study Design and Setting: Patients aged 15 years or older, registered between 2011 and 2016 in the Swedish national trauma registry, SweTrau, were included. Three data set groups were created: high- and low-
Artificial intelligence (AI) algorithms for automated classification of skin diseases are available to the con-sumer market. Studies of their diagnostic accuracy are rare. We assessed the diagnostic accuracy of an open-access AI application (Skin Image Search™) for recognition of skin diseases. Clinical images including tumours, infective and inflammatory skin diseases were collected at the Depart
Background and aim: Repeat hepatectomy is increasingly performed for the management of recurrent colorectal liver metastases (CRLM). The aim of this study was to evaluate longterm functional liver volume (FLV) after a second hepatic procedure and to measure survival outcome. Methods: In this retrospective cohort study, patients treated for recurrent CRLM in the years 2005-2015 at two liver centers
Background: Epigenetic alterations have been recognized as important contributors to the pathogenesis of PDAC. However, the role of histone variants in pancreatic tumor progression is still not completely understood. The aim of this study was to explore the expression and prognostic significance of histone protein variants in PDAC patients. Methods: Liquid chromatography-tandem mass spectrometry (
A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZH→ + -cc is studied. A data set with an integrated luminosity of 36.1 fb-1 of pp collisions at s=13TeV recorded by the ATLAS experiment at the LHC is used. The H→cc signature is identified using charm-tagging algorithms. The observe
The gram-positive, endospore-forming bacterium Bacillus subtilis contains several membrane-bound c-type cytochromes. We have isolated a mutant pleiotropically deficient in cytochromes c. The responsible mutation resides in a gene which we have named ccdA (cytochrome c defective). This gene is located at 173 degrees on the B. subtilis chromosome. The ccdA gene was found to be specifically required
The Parkinson's disease (PD) home diary is frequently used in clinical trials to measure efficacy of medical treatments for motor fluctuations in advanced PD. This prospective study in fluctuating PD patients examines the validity of the diary for quantification of motor states in comparison to direct clinical observation. 51 patients (median age: 65 years, disease duration: 11 years) completed th
Den första av två artiklar rörande det fängelse, den s k proban, som Lunds universitet hade under den tid lärosätet ägde egen jurisdiktion över anställda och studenter. Denna första del behandlar fenomenet med skol- och universitetsfängelser generellt samt Lunds universitets specifika sådana under 1600- och 1700-talen.
Evenemangsbranschen kopplad till Sveriges idrotts- och friluftsliv har påverkats kraftigt av pandemin. I det korta perspektivet har tusentals människors jobb och fritid påverkats då aktiviteter uteblivit och evenemang ställts in. De långsiktiga konsekvenserna kan leda till en förändrad syn på hur man i framtiden kommer att resa, delta i evenemang och använda arenor. Detta får i sin tur konsekvense
Popular Abstract in Swedish Bakgrund I Sverige erbjuds samtliga gravida kvinnor ett rutinultraljud vid 18-20 graviditetsveckor. Syftet med undersökningen är att fastställa antalet foster, uppskatta graviditetslängd samt granska fosteranatomin för att upptäcka eventuella missbildningar. En del missbildningar kan man se med ultraljud, men långtifrån alla. Att redan under graviditeten känna till om The aim was to evaluate first trimester nuchal translucency (NT) measurement for detection and risk assessment of fetal malformations and fetal loss. 39 572 pregnant women were randomised to either a routine ultrasound scan at 12-14 weeks including NT measurement or to a routine scan at 18-20 weeks. Prenatal diagnosis of major congenital heart malformations was compared between the two groups. In
BACKGROUND: The majority of allergy patients who seek medical advice are seen in primary care. In-service training of professionals in general practice is needed in order to increase knowledge among primary care clinicians about allergy. Therefore it is important to establish a consensus about what primary care professionals should be able to do, and what the public can expect. We sought to identi
The implementation of circular initiatives requires certain capabilities and knowledge that traditional business models often lack, requiring new perspectives and external collaborations. This paper explores the competency needs and partnership dynamics of established companies collaborating for business model innovation for circularity through a case study of a gap exploiter business model, a com
BackgroundThere is a need for the development of accurate, accessible and efficient screening instruments, focused on early-stage detection of neurocognitive disorders. The Geras Solutions cognitive test (GSCT) has showed potential as a digital screening tool for cognitive impairment but normative data are needed.ObjectiveThe aim of this study was to obtain normative data for the GSCT in cognitive
Context. The Milky Way nuclear star cluster (MWNSC) is located in the Galactic centre, together with the Milky Way nuclear stellar disc (MWNSD), and they dominate the gravitational potential within the inner 300 pc. However, the formation and evolution of the two systems and their possible connections are still under debate. Aims. We reanalysed the low-resolution KMOS spectra in the MWNSC with the
