A search for the nonresonant Λc+→pμ+μ- decay is performed using proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the LHCb experiment, corresponding to an integrated luminosity of 5.4 fb-1. No evidence for the decay is found in the dimuon invariant-mass regions where the expected contributions of resonances is subdominant. The upper limit on the branching fraction of th
InP quantum dots have emerged as a promising ecofriendly alternative to cadmium-based QDs for next-generation display applications. However, red-emitting InP QDs synthesized via aminophosphine precursors still suffer from broad emission spectra and limited stability. In this study, we present a strain-engineered InP/ZnSe/ZnSexS1-x/ZnS QD structure featuring a gradient alloyed ZnSexS1-x shell that
The decays of the B+ meson to the final state D∗−Ds+π+ are studied in proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb−1. The ratio of branching fractions of the B+→D∗−Ds+π+ and B0→D∗−Ds+ decays is measured to be 0.173 ± 0.006 ± 0.010, where the first uncertainty is statistical and t
Although Fourier Neural Operators (FNOs) are computationally efficient and theoretically mesh-independent, their standard formulation assumes periodic boundary conditions and rectangular domains. When applied to non-periodic conditions, FNOs often exhibit oscillations, edge effects, and reduced accuracy. To mitigate these issues, this study investigates modifications to the baseline FNO, including
Otaliga mängder kritisk information om vår hälsa spolas ner varje dag. En toalettsits med osynligt inbyggd radar kan ta tillvara på denna information. Alla besöker toaletten varje dag, därav är den fylld av kliniskt relevant information, som hittills sällan använts för att övervaka hälsan. Förändringar i urin- och avföringsmängd, samt avföringens konsistens kan vara tidiga tecken på sjukdom, men rConstipation and irregular bowel movements are a daily challenge in elderly care, especially among patients with dementia who struggle to report their own toilet habits. This thesis investigates the possibility of using millimeter-wave pulsed coherent radar to passively monitor toilet visits and estimate both stool consistency and excreted quantity of urine and feces. This involved constructing a
This study investigates the concept of Selective Intentional Non-Compliance (SINC) in aviation. Deliberate, context-driven deviations from procedures motivated by safety in response to dynamic operational conditions. Based on a survey of 39 European commercial pilots, we analysed the prevalence, motivations, and perceived outcomes of procedural deviations. Nearly 43% reported deviating from s
In this article, we examine how the death of an author affects the value negotiation surrounding his or her oeuvre. As Barbara Herrnstein Smith has argued, literary value is not a fixed category but rather something that is created and negotiated in relation to various contexts and settings. For a high evaluation of the oeuvre of a given author – or a particular work – to be maintained, this value
In this article, we analyze the reception of the AI-generated poetry collection Ammaseus horisont: AI tolkar Karin Boye (2020) and discuss the more general debate about AI-generated literature in the Swedish press since November 2022, when OpenAI made ChatGPT available to the public. Specifically, we analyze the ways in which Swedish critics construct the literary value of Ammaseus horisont and un
This study explores how Chilean university students perceive entrepreneurship, exploring whether they see it as an opportunity to address societal challenges or primarily as an enterprise creation. The research focuses on how these perceptions vary by gender in front of sociodemographic, academic, and institutional influential factors. Using a quantitative approach, we collected data from a sample

While nostalgia has been a prominent theme in consumer research, little research explicitly addresses its dark side. This conceptual paper unpacks nostalgic echo chambers and their three axiological features of polarization, singularization, and ideologization to inform future consumer research on the implications of nostalgic echo chambers for consumers and society.
This paper describes measurements of the transverse momentum spectra of W and Z bosons produced in proton–proton collisions at centre-of-mass energies of s=5.02 TeV and s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, W→ℓν and Z→ℓℓ (ℓ=e or μ), and for W events further separated by charge. The data were collected in 2017
A search for CP violation in the decay kinematics and vector-boson fusion production of the Higgs boson is performed in the H → ZZ* → 4ℓ (ℓ = e, μ) decay channel. The results are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector from 2015 to 2018, corresponding to an integrated luminosity of 139 fb−1. Matrix element-ba
This doctoral thesis presents a comprehensive investigation into action-detected two-dimensional electronic spectroscopy (A-2DES), from the technical development of a state-of-the-art apparatus to its application in elucidating ultrafast dynamics in advanced materials and biological systems. The work is founded on the design and implementation of an A-2DES setup centered on a single acousto-optic
A summary of the constraints from searches performed by the ATLAS collaboration for the electroweak production of charginos and neutralinos is presented. Results from eight separate ATLAS searches are considered, each using 140 fb−1 of proton-proton data at a centre-of-mass energy of s = 13 TeV collected at the Large Hadron Collider during its second data-taking run. The results are interpreted in
Template-assisted crystal engineering provides a powerful strategy for constructing ordered networks tailored to organic electronic applications. We introduce a solution-based strategy to fabricate crystalline needle-like arrays of charge-transfer complexes (CTCs) between electron-donating benzo(ghi)perylene (BP) and electron-accepting TCNQ. Well-defined square-crystals of BP polymorphs were emplo
As artificial intelligence continues to evolve, neuromorphic technologies, which emulate biological neural networks, are increasingly seen as a promising direction. Two-dimensional materials are considered promising for neuromorphic applications due to their tunable electrical and optoelectronic properties. In this work, a back-gated tin disulfide (SnS2) field-effect transistor (FET) is electrical
Cognitive decline associated with aging and neuroinflammation has been linked to gut microbiota dysbiosis and systemic inflammation, potentially mediated through the gut–brain axis. Bioactive peptides have shown potential as therapeutic candidates for neurodegenerative and neuroinflammatory disorders. While the walnut-derived peptide EVSGPGYSPN (EV-10) has demonstrated cognitive benefits, the ther
