Cold activation in PT-INR samples–Myth or reality in the modern laboratory?
Guidelines on storage for samples intended for Prothrombin Time–International Normalized Ratio (PT-INR) analysis have changed over time, sometimes advising against cold storage due to presumed cold activation of the coagulation cascade. Previous studies on PT-INR storage have mainly been underpowered, performed in glass tubes, and not in a modern laboratory setting. In this study, we re-analyzed 1
Federated Resource Allocation for HPC Services
This paper presents an implementation of a federated resource allocation system (Puhuri), which offers a full set of functions from the application phase for computing infrastructure resources to consumption reporting. The implementation is based on the Puhuri project of Nordic e-Infrastructure Collaboration (NeIC) [1]. Shared research infrastructures, particularly high-performance computers, nece
Constraints on simplified dark matter models involving an s-channel mediator with the ATLAS detector in pp collisions at s=13 TeV
This paper reports a summary of searches for a fermionic dark matter candidate in the context of theoretical models characterised by a mediator particle exchange in the s-channel. The data sample considered consists of pp collisions delivered by the Large Hadron Collider during its Run 2 at a centre-of-mass energy of s=13TeV and recorded by the ATLAS detector, corresponding to up to 140 fb-1. The
Gold-silver alloy nanoparticle formation via spark ablation : the dynamics of material mixing
Binary nanoparticles (BNPs), composed of two distinct materials, offer tailored properties advantageous for various applications, including enhanced catalytic, magnetic, and optical behavior. Among the synthesis methods for BNPs, spark ablation stands out for its capability to produce multicomponent nanostructures with tunable compositions. This study investigates the mixing dynamics of material v
Epistemic agency, embodied knowledge and power in the digital space : The case of Nadia Murad
This chapter takes an interest in the construction of gendered knowledge in the digital space. Through an analysis of the digital activism of the epistemic agent Nadia Murad, survivor of the genocide against the Yazidi, the chapter investigates how she departs from her personal, embodied experience of ISIS violence to advocate for justice, recognition and reparation. Through the methodological app

Pixel-Perfect Structure-From-Motion With Featuremetric Refinement
Finding local features that are repeatable across multiple views is a cornerstone of sparse 3D reconstruction. The classical image matching paradigm detects keypoints per-image once and for all, which can yield poorly-localized features and propagate large errors to the final geometry. In this article, we refine two key steps of structure-from-motion by a direct alignment of low-level image inform
Measurements of Lund subjet multiplicities in 13 TeV proton-proton collisions with the ATLAS detector
This Letter presents a differential cross-section measurement of Lund subjet multiplicities, suitable for testing current and future parton shower Monte Carlo algorithms. This measurement is made in dijet events in 140 fb−1 of s=13 TeV proton–proton collision data collected with the ATLAS detector at CERN's Large Hadron Collider. The data are unfolded to account for acceptance and detector-related
Determination of the Relative Sign of the Higgs Boson Couplings to W and Z Bosons Using WH Production via Vector-Boson Fusion with the ATLAS Detector
The associated production of Higgs and W bosons via vector-boson fusion is highly sensitive to the relative sign of the Higgs boson couplings to W and Z bosons. In this Letter, two searches for this process are presented, using 140 fb^{-1} of proton-proton collision data at sqrt[s]=13 TeV recorded by the ATLAS detector at the LHC. The first search targets scenarios with opposite-sign couplings of
The K2-24 planetary system revisited by CHEOPS
The planetary system K2-24 is composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large transit time variations (TTVs), and it is an excellent laboratory to search for signatures of planetary migration. Previous studies performed with K2, Spitzer, and RV data tentatively claimed a significant non-zero eccentricity for one or both planets, possibl
Diverse roles of Primary Health Care in COVID-19 vaccination across 28 European countries - Insights from the Eurodata study
BACKGROUND: The COVID-19 vaccination campaign in several European countries involved collaboration between public health and Primary Health Care (PHC). OBJECTIVE: To highlight the role of PHC professionals in the COVID-19 vaccination rollout, specifically in terms of vaccine administration, communication and contributing to vaccination population coverage. METHODS: A descriptive retrospective stud
Vulnerability and life style factors among university students in Ethiopia: Assessing risky sexual behavior, exposure to violence and patterns of substance use and alcohol consumption
Background: University students are at a transitional stage in life characterized by increased independence, autonomous decision-making, reduced parental supervision, and heightened susceptibility to peer pressure.These dynamics expose them to various risks, including risky sexual behaviors, violence, and use of substances and alcohol. These risky behaviors often result in serious negative consequ

Urine Glycosaminoglycan Scores for Surveillance of Recurrence in Intermediate- and High-risk Nonmetastatic Clear Cell Renal Cell Carcinoma-An Observational Prospective Multicentre Diagnostic Test Cohort Study
BACKGROUND AND OBJECTIVE: Nonmetastatic (M0) clear cell renal cell carcinoma (ccRCC) recurs in ∼20% of patients within 5 yr after surgery. With no biomarkers available, recurrence detection relies on radiological imaging. Urine glycosaminoglycan profiles (GAGomes) were previously associated with M0 ccRCC recurrence. We conducted an observational prospective multicentre diagnostic test cohort study
Is There Backward Generation in the Institutional Realm?
Over the last decade it has been pointed out by several philosophers that not all Status Function Declarations are synchronic: some such declarations are directed toward the absolute past. Such Status Function Declarations are perplexing if one is an ontic realist with respect to institutional properties and states of affairs. If successful, such Status Function Declarations seem to change the absOver the last decade it has been pointed out by several philosophers that not all Status Function Declarations are synchronic: some such declarations are directed toward the absolute past.

Parity non-conservation and pair correlation in heavy atomic systems
The increased accuracy of the experiments studying parity non-conserving effects in atoms calls for improvement also in the atomic calculations which are necessary to connect the experimental results to fundamental parameters. We show how the method of iterative solution of the two-dimensional “pair equation” can be used to treat the effect of pair correlation to all orders, also in the calculatio
Parity non-conserving effects in atomic systems
Atoms through the looking glass - A relativistic challenge
The search for weak-interaction-induced atomic parity nonconservation, initiated in the 1970s, challenges both theory and experiment Since the weak interaction is very short range, the atomic effects increase rapidly with nuclear charge, as Z3. The focus has thus been on heavy atoms, where relativistic effects are essential, and nuclear size must be taken into account. The generalization of atomic
