We report on the multi-wavelength observations of PKS 1510-089 (a flat spectrum radio quasar (FSRQ) at z = 0.361) during its high activity period between 2008 September and 2009 June. During this 11 month period, the source was characterized by a complex variability at optical, UV, and gamma-ray bands, on timescales down to 6-12 hr. The brightest gamma-ray isotropic luminosity, recorded on 2009 Ma

Despite our fine-grain anatomical knowledge of the cerebellar cortex, electrophysiological studies of circuit information processing over the last fifty years have been hampered by the difficulty of reliably assigning signals to identified cell types. We approached this problem by assessing the spontaneous activity signatures of identified cerebellar cortical neurones. A range of statistics descri

We study Hamming versions of two classical clustering problems. The Hamming radius p-clustering problem (HRC) for a set S of k binary strings, each of length n, is to find p binary strings of length n that minimize the maximum Hamming distance between a string in S and the closest of the p strings; this minimum value is termed the p-radius of S and is denoted by varrho. The related Hamming diamete

Popular Abstract in Swedish Graviditetsdiabetes (GDM) innebär att förhöjd glukosnivå i blodet (blodsocker) upptäckts hos en kvinna när hon är gravid. GDM behandlas med anpassad kost, fysisk aktivitet, och när det behövs även insulin, vilket tillsammans har visats motverka de ökade riskerna vid graviditet och förlossning för mamma och barn. Glukosnivåerna normaliseras nästan alltid efter förlossninBackground: Gestational diabetes mellitus (GDM) is associated with risks during pregnancy, during delivery, and in later life with a substantial risk of subsequent diabetes. The worldwide prevalence of GDM is increasing, but varies with differences in diagnostic methods and population characteristics. Results: Capillary glucose concentrations were found to be higher than venous glucose concentrat

Context. Metal-rich globular clusters provide important tracers of the formation of our Galaxy. Moreover, and not less important, they are very important calibrators for the derivation of properties of extra-galactic metal-rich stellar populations. Nonetheless, only a few of the metal-rich globular clusters in the Milky Way have been studied using high-resolution stellar spectra to derive elementa

Estimates of relevant source area of pollen (RSAP) and relative pollen productivity (PPE) are critical parameters for quantitative reconstructions of past vegetation and land cover. This study provides estimates for PPE relative to Poaceae for ten taxa, characterizing the cultural landscape of south Estonia and the RSAP for 40 lakes with an average radius of approximately 100 m (22-274 m, average

The world production of paper and paperboard products, which increased 3.3% per year since 1980, reached 243 million tonnes in 1991 and is expected to continue to grow by about 2.5% per year over the next decade. Consumption levels in 1990 ranged from 2.8 kg per capita in India to 313 kg per capita in the United States. The biggest producers of pulp are the United States, Canada and the Scandinavi

Objective This study was undertaken to analyze standardized mortality ratios (SMRs) and causes and predictors of death in primary Sjögren's syndrome (SS) diagnosed according to 3 different classification criteria sets (the Copenhagen criteria, the European criteria, and the American-European consensus criteria (AECC). Methods A linked registry study using information from the Malmö Primary SS Reg

Landskapsformen drumlin har länge diskuterats inom akademin och den här studen syftar till att sprida lite ljus över dom. Genom att kartlägga två drumlinområden runt sjön Åsnen i Småland, södra Sverige har deras utsträckning kartlagts med en precision som länge ansetts omöjligt. Detta gjordes genom att använda hög upplösta hillshade modeller framtagna från LiDAR data för att efter att ha analyseraThe landform group called drumlins has since long been enigmatic; this study aims to shed some light on them. By mapping their extent in two areas around Lake Åsnen, Småland, southern Sweden, their extent and prop-erties have been mapped with a level of detail that would have been next to impossible just a few years ago. The method used in this study utilized LiDAR derived high resolution hillshad

This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. Inter-comparison tests demon

Introduction: Side-stream residue, oat okara, from the oat-milk production contains valuable nutrients but possesses a high risk of microbial spoilage. Valorisation of oat okara is therefore important to make sure that the oat beverage production stays sustainable. In this project, High-pressure processing (HPP), heat treatment and Lactobacillus fermentation have been evaluated for their microbial

Sveriges geologiska undersökning (SGU) har ägnat flera år åt att undersöka den svenska berggrunden för att utreda möjligheterna för geologisk lagring av koldioxid. Djupt liggande akviferer anses ha störst potential och den kambriska Faluddensandstenen, som finns i Östersjön öster om Gotland, visar stor potential som lagringsakvifer. I denna studie har borrkärnan St. Sutarve-2018 från södra GotlandThe Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer. In this study, the drill core St. Sutarve

Context. To study the evolution of Li in the Galaxy it is necessary to observe dwarf or subgiant stars. These are the only long-lived stars whose present-day atmospheric chemical composition reflects their natal Li abundances according to standard models of stellar evolution. Although Li has been extensively studied in the Galactic disk and halo, to date there has only been one uncertain detection

The aim of the present study was to investigate the size-selectivity of two different synthetic dialyzing membranes, having widely differing sieving properties, with respect to their handling of polydispersed fluorescein isothiocyanate (FITC)-Ficoll, FITC-dextran and of proteins, i.e. I-125-human serum albumin (RISA) and I-125-myoglobin (Myo). Are Ficoll and dextran, compared to proteins, "hyperpe

Background: Exposure to polycyclic aromatic hydrocarbons (PAHs) has been associated with cardiovascular diseases in adulthood, but studies examining childhood origins are scarce. Objective: To examine associations of childhood PAH exposure with cardiometabolic risk indicators in childhood and adolescence along with differences by sex. Methods: Urinary PAH metabolites [Σ1,2,3-hydroxyphenanthrene (Σ

INTRODUCTION: The soluble urokinase-type plasminogen activator receptor (suPAR) has recently been associated with a decline in kidney function and incidence of chronic kidney disease in patients with cardiovascular disease undergoing cardiac catheterization, yet little is known whether suPAR is associated with deterioration of kidney function in the general population.METHODS: In the population-ba

Background/Objectives: There is still no consensus as to whether patients with upfront resectable synchronous colorectal liver metastases (sCRLM) should receive neoadjuvant treatment prior to liver surgery. Two randomized controlled trials have assessed the role of peri-operative chemotherapy in sCRLM; neither have shown a survival benefit in the neoadjuvant group. The aim of this population-based

Synthetic aperture radar (SAR) remote sensing (RS) technology is an ideal tool to map flooded areas on account of its all-time, all-weather imaging capability. Existing SAR data-based change detection approaches lack well-discriminant change indices for reliable floodwater mapping. To resolve this issue, an unsupervised change detection approach, made up of two main steps, is proposed for detectin

Aim: Extremes in sleep duration play an important role in the development of type 2 diabetes. We examined the associations between sleep duration and sleep debt with estimates of insulin sensitivity and insulin secretion. Methods: Data were derived from the European multi-centre EGIR-RISC study. Sleep duration and sleep debt were derived from a sleep questionnaire asking about sleeping time during

The association between breast cancer risk defined by the Tyrer-Cuzick score (TC) and disease prognosis is not well established. Here, we investigated the relationship between 5-year TC and disease aggressiveness and then characterized underlying molecular processes. In a case-only study (n = 2474), we studied the association of TC with molecular subtypes and tumor characteristics. In a subset of
