Impact melt rocks formed during hypervelocity impact events are ideal for studying impact structures. Here, we describe impact melt rock samples collected proximal to the 31 km wide 58 Ma Hiawatha impact structure, northwest Greenland, which is completely covered by the Greenland Ice Sheet. The melt rocks contain diagnostic shock indicators (e.g., planar deformation features [PDF] in quartz and sh
We present new data for the ∼3.0 Ga Maniitsoq Norite Belt of the Akia Terrane, West Greenland, with the aim of understanding its petrogenesis. The Maniitsoq Norite Belt is hosted in regional tonalite-trondhjemite-granodiorite (TTG) and dioritic orthogneisses, intruded by later sheets of TTG and granite pegmatites, and comprises two main rock types: plagioclase-rich “norites” and pyroxene-rich “mel
The United Nations (UN) Intergovernmental Negotiating Committee (INC) has completed its second round of negotiations on a new international legally binding instrument to ‘end plastic pollution’. This paper examines the results of the second session of negotiations, which took place May 29–June 2, 2023, and analyses the trends, barriers, and themes shaping the emerging legally binding instrument. T
Plutonium zwierleini is a large plutoniumid centipede of great evolutionary interest, occurring with isolated populations along the western Mediterranean area, from Spain to Italy. Due to its rarity and the extreme paucity of available records, P. zwierleini is among the least known Mediterranean chilopods, and scarce information is currently available on its ecology and natural history. Based on
Biological staging of individuals with Alzheimer’s disease (AD) may improve diagnostic and prognostic workup of dementia in clinical practice and the design of clinical trials. In this study, we used the Subtype and Stage Inference (SuStaIn) algorithm to establish a robust biological staging model for AD using cerebrospinal fluid (CSF) biomarkers. Our analysis involved 426 participants from BioFIN
Background: OBQ11 was developed in a Swedish context. To evaluate occupational balance, accurate self-rating instruments in the native language are needed. Aim: The aim was to investigate the measurement properties of the Danish version of OBQ11, using the Rasch analysis. Method: Data for the analysis of the Danish version of OBQ11 (OBQ11-DK) was gathered online, and all full data records (n 366)
BACKGROUND: The ongoing TANGO2 (Telephone Assisted CPR. AN evaluation of efficacy amonGst cOmpression only and standard CPR) trial is designed to evaluate whether compression-only cardiopulmonary resuscitation (CPR) by trained laypersons is noninferior to standard CPR in adult out-of-hospital cardiac arrest. This pilot study assesses feasibility, safety, and intermediate clinical outcomes as part
Winter warming events (WWEs) are short-lasting events of unusually warm weather, occasionally combined with rainfall, which can cause severe ecosystem impacts by altering ground temperatures and water fluxes. Despite their importance, how large-scale ecosystem models perform in depicting the impacts of WWEs remain largely unknown. The frequency and intensity of WWEs will likely increase further in
In this talk recent progress in studying the short-distance properties of the hadronic light-by-light contribution to the muon g−2 is described. The intermediate and short-distance part contributes a large part of the error of the theoretical prediction as described in the white paper [1]. We showed that the massless quark-loop is the first term in a systematic expansion at short-distances, a resu
Sarcomas represent a broad and heterogenous group of rare tumors. For some subtypes, there arepathognomonic genetic alterations available, while for others such alterations remain to be identified.Especially in entities that harbor large numbers of complex genetic changes, much still remains to beunderstood. One such entity is osteosarcoma, the most common primary bone tumor. Although primarilyaff
We regard the classic Thue–Morse diffraction measure as an equilibrium measure for a potential function with a logarithmic singularity over the doubling map. Our focus is on unusually fast scaling of the Birkhoff sums (superlinear) and of the local measure decay (superpolynomial). For several scaling functions, we show that points with this behavior are abundant in the sense of full Hausdorff dime
Silica has rarely been used as a seed particle material in acoustic trapping of nanoparticles. Here we use fluorescent nanoparticles, which are frequently used as a model system, to demonstrate that throughput and nanoparticle trapping efficiency can be improved by using silica seed particles as opposed to traditionally used polystyrene seed particles. The 10 times larger dipole scattering coeffic
This study aims to investigate the feasibility of enhancing the charge collection efficiency (CCE) of a transmission chamber by reconfiguring its design and operation. The goal was to extend the range of dose-per-pulse (DPP) values with no or minimal recombination effects up to the ultra-high dose rate (UHDR) regime. The response of two transmission chambers, with electrode distance of 1 mm and 0.
The complement system plays a central role in the pathogenesis of Systemic Lupus Erythematosus (SLE), but most studies have focused on the classical pathway. Ficolin-3 is the main initiator of the lectin pathway of complement in humans, but its role in systemic autoimmune disease has not been conclusively determined. Here, we combined biochemical and genetic approaches to assess the contribution o
BACKGROUND: Little is known about risks of hypertensive disorders of pregnancy in both first-and second-generation immigrant women in Europe and other Western countries; such knowledge may help elucidate the influence of genetic versus social factors on such risks. We aimed to study both first-and second-generation immigrant women for the presence of all types of hypertension (preexisting hyperten
Oat (Avena sativa) is a cereal grain rich in fibers, proteins, vitamins and minerals. Oats have been linked to several health benefits, such as lowering blood cholesterol levels, counteracting cardiovascular disease and regulating blood sugar levels. This study aimed to characterize two new oat lines with high β-glucan content emanating from ethyl methyl sulphonate mutagenesis on the Lantmännen el
We present the results on the relativistic six-pion scattering amplitude at low energy, calculated at O(p4) within the framework of the massive O(N) nonlinear sigma model extended to the next-to-leading order in the chiral counting. For N = 3, this approach corresponds to the two(quark)-flavor Chiral Perturbation Theory. We also present the expressions for the pion mass, pion decay constant and th
A prerequisite to applying 10Be in natural archives for solar and geomagnetic reconstructions is to know how 10Be deposition reflects atmospheric production changes. However, this relationship remains debated. To address this, we use two state-of-the-art global models GEOS-Chem and ECHAM6.3-HAM2.3 with the latest beryllium production model. During solar modulation, both models suggest that 10Be de
Background and Clonal haematopoiesis of indeterminate potential (CHIP), the age-related expansion of blood cells with preleukemic mutaAims tions, is associated with atherosclerotic cardiovascular disease and heart failure. This study aimed to test the association of CHIP with new-onset arrhythmias.Methods UK Biobank participants without prevalent arrhythmias were included. Co-primary study outcome
Archaeooides originally refers to a group of early Cambrian globular microfossils with regularly arranged nodular surface ornaments, and of a diameter ranging from less than 400 μm to more than 2 mm. The traditional taxonomy assigns all Archaeooides-like microfossils to a single morphotaxon, Archaeooides granulatus, irrespective of their differences in size and surface ornamentation. Archaeooides
