Mid-Infrared Generated Laser-Induced Grating Signals in Methane-Containing Gas Mixtures as Indicators of Composition, Pressure, and Temperature

The present work is aimed at studying how spatially periodic modulations of the refractive index of the medium, i.e., laser-induced gratings (LIGs), generated in a gas mixture containing methane (CH4) by nanosecond pulses of resonant mid-infrared laser radiation, can be used to measure various gas parameters. It is investigated to what extent the temporal profiles of the LIG signals, recorded as t

Genetic evidence for T-wave area from 12-lead electrocardiograms to monitor cardiovascular diseases in patients taking diabetes medications

Aims Many studies indicated use of diabetes medications can influence the electrocardiogram (ECG), which remains the simplest and fastest tool for assessing cardiac functions. However, few studies have explored the role of genetic factors in determining the relationship between the use of diabetes medications and ECG trace characteristics (ETC). Methods Genome-wide association studies (GWAS) were

Att införa styrmedel : Utmaningar och möjligheter för klimatpolitiken

En ambitiös politik och effektiva styrmedel behövs för en snabb klimatomställning av samhället. Det finns en stor palett av möjliga styrmedel och olika styrmedel fungerar olika bra beroende på vilka hinder för omställningen de är tänkta att hantera. Men även om det i stort är känt vad som behöver göras, vilka styrmedel som finns tillgängliga och hur de bäst kan användas är en annan fråga hur dessa

The Relationship between p-tau217, p-tau231, and p-tau205 in the Human Brain Is Affected by the Cellular Environment and Alzheimer’s Disease Pathology

The levels of p-tau217 and p-tau231 in cerebrospinal fluid (CSF) are associated with early amyloid beta (Aß) changes in the brain, while the CSF levels of p-tau205 are foremost related to tau pathology in the later stages of the disease. To investigate if the three p-tau variants are found to the same degree in different tau structures and if their co-localization is affected by the diagnosis and

Clog : A Declarative Language for C Static Code Checkers

We present Clog, a declarative language for describing static code checkers for C. Unlike other extensible state-of-the-art checker frameworks, Clog enables powerful interprocedural checkers without exposing the underlying program representation: Clog checkers consist of Datalog-style recursive rules that access the program under analysis via syntactic pattern matching and control flow edges only.

Prophylactic Treatment of Children with Hemophilia in Sweden

Hemophilia A/B are caused by deficiency or lack of coagulation factors VIII (FVIII) or factor IX (FIX), respectively, in plasma. A person with hemophilia develops bleeding in the joints and muscles at an early age, which, if left untreated, leads to early arthropathy. Preventive treatment can be achieved by regular (prophylactic) administration of FVIII/FIX. In 1958, this was implemented on a smal

I Danmark reguleres det sociale område i høj grad af rammelovgivning, som uddelegerer myndighed, regulerer gennem formålsbeskrivelser og gør det muligt for såkaldte velfærdsprofessionelle at udøve skøn. Denne artikel undersøger, hvordan samspillet mellem velfærdsprofessionelles opfattelser og de ting, der på forskellig vis regulerer deres praksis, får betydning for konstruktionen af legalitet i de

SAXS data modelling for the characterisation of ion tracks in polymers

Here, we present new models to fit small angle X-ray scattering (SAXS) data for the characterization of ion tracks in polymers. Ion tracks in polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI) and polymethyl methacrylate (PMMA) were created by swift heavy ion irradiation using 197Au and 238U with energies between 185 MeV and 2.0 GeV. Transmission SAXS measurements were performed

Goal-oriented error estimation for beams on elastic foundation with double shear effect

In this paper, goal-oriented error estimation for Timoshenko beams on Pasternak foundation, which involves double shear effect, is performed. The constitutive relation error (CRE) estimation is used in finite element analysis (FEA) to acquire strict bounds on quantities of interest. Due to the coupling of the displacement field and the internal force field in the equilibrium equations of the beam,

The emergence of pelagic calcification and its influence on seawater chemistry in the Upper Triassic.

After the early biomineralisation event in the early Paleozoic (Cambrian –Ordovician; 541 – 443.8 Ma), the Late Triassic (237 – 201.3 Ma) represents another key period of biomineralisation with the onset of the Mesozoic plankton radiation. In the Carnian (237 – 227 Ma), the first calcifying dinoflagellates are recorded followed by the nannoliths in the middle Norian (Alaunian) and the coccolithoph

Predictive value of individual serum neurofilament light chain levels in short-term disease activity in relapsing multiple sclerosis

Background: The assessment of serum neurofilament light chain (sNFL) has emerged as a diagnostic and prognostic tool in monitoring multiple sclerosis (MS). However, the application of periodic measurement in daily practice remains unclear. Objective: To evaluate the predictive value of individual sNFL levels in determining disease activity in patients with relapsing MS (RMS). Methods: In this two-

Process-evaluation of forest aerosol-cloud-climate feedback shows clear evidence from observations and large uncertainty in models

Natural aerosol feedbacks are expected to become more important in the future, as anthropogenic aerosol emissions decrease due to air quality policy. One such feedback is initiated by the increase in biogenic volatile organic compound (BVOC) emissions with higher temperatures, leading to higher secondary organic aerosol (SOA) production and a cooling of the surface via impacts on cloud radiative p

Life-Cycle Effects of Comprehensive Sex Education

Sex education can impact pupils’ sexual activity and convey the social norms regarding family formation and responsibility, which can have significant consequences to their future. To investigate the life-cycle effects of social norm transmission, this study draws on the introduction of comprehensive sex education in the curriculum of Swedish primary schools during the 1940s to the 1950s. Inspired

Projected effects of climate change and forest management on carbon fluxes and biomass of a boreal forest

Boreal forests are key to global carbon (C) sequestration and storage. However, the potential impacts of climate change on these forests could be profound. Nearly 70 % of the European boreal forests are intensively managed, but our understanding of the combined effects of forest management and climate change on the forest's integral role as a C sink is still limited. In this study, we aim to fill

Combining camera trap surveys and IUCN range maps to improve knowledge of species distributions

Reliable maps of species distributions are fundamental for biodiversity research and conservation. The International Union for Conservation of Nature (IUCN) range maps are widely recognized as authoritative representations of species’ geographic limits, yet they might not always align with actual occurrence data. In recent area of habitat (AOH) maps, areas that are not habitat have been removed fr

A Multidimensional Readiness Index for the Electrification of the Transportation System in China, Norway, and Sweden

The main objective of this paper is to develop a readiness index model that can serve as an analytical tool for exploring the achievements of the electrification of transportation systems. We have applied this readiness index model to evaluate the readiness positioning of China, Norway, and Sweden towards transportation electrification. We have chosen these three countries as they represent divers

Long-term health outcomes associated with hydration status

Body water balance is determined by fundamental homeostatic mechanisms that maintain stable volume, osmolality and the composition of extracellular and intracellular fluids. Water balance is maintained by multiple mechanisms that continuously match water losses through urine, the skin, the gastrointestinal tract and respiration with water gains achieved through drinking, eating and metabolic water
