Manganese carbonyl compounds can release CO when exposed to light, potentially becoming photochemically activated CO-releasing molecules (photoCORMs). Several studies have demonstrated the behavior in the ground state when irradiated with light. However, much remains to be discovered about the chemistry of photoCORMs with uncoordinated ligand moieties and the excited states of these compounds. Thi

High-momentum two-particle correlations are a useful tool for studying jet-quenching effects in the quark-gluon plasma. Angular correlations between neutral-pion triggers and charged hadrons with transverse momenta in the range 4-12 GeV/c and 0.5-7 GeV/c, respectively, have been measured by the PHENIX experiment in 2014 for Au+Au collisions at sNN=200 GeV. Suppression is observed in the yield of h

The TESS mission searches for transiting exoplanets by monitoring the brightness of hundreds of thousands of stars across the entire sky. M-type planet hosts are ideal targets for this mission due to their smaller size and cooler temperatures, which makes it easier to detect smaller planets near or within their habitable zones. Additionally, M dwarfs have a smaller contrast ratio between the plane

Bakgrund: Den kurativa behandlingen för resektabla lokalt avancerade stadier av cancer i munhålan innefattar i regel en kombination av kirurgi och radioterapi (RT). Huruvida RT bör ges först och därefter följas av kirurgi, eller om tumören bör opereras bort först, följt av RT postoperativt, har dock inte studerats i någon större omfattning.Syfte: Denna avhandling undersöker olika aspekter av pre- Background: The curatively intended treatment for resectable locally advanced stages of oral cavity cancer (OCC) generally involves a combination of surgery and radiotherapy (RT). However, whether to apply RT first and then proceed with surgery, or to resect the cancer and subsequently administer RT, has not been extensively studied. Aims: This thesis examines various aspects of pre- versus postop

Background: Reliable data on optimal fluid management in the perioperative period for patients with advanced ovarian cancer undergoing cytoreductive surgery is limited. These patients often present with malignant ascites and are prone to significant fluid shifts perioperatively. For this reason, our objective was to define clinical targets for optimal fluid balance and determine whether initial as

We seek to clarify the impact of the Genetic Aptitude for Educational Attainment (GAEA) on risk for 10 psychiatric disorders divided into 4 groups: Internalizing, Externalizing, Eating/Compulsive and Psychotic. Educational attainment and psychiatric and substance use disorder information were obtained from national Swedish registries. GAEA and disorder-specific family genetic risk score (FGRS) wer

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

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

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

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

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

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

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

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 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

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

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
