Observation of Single-Top-Quark Production in Association with a Photon Using the ATLAS Detector

This Letter reports the observation of single top quarks produced together with a photon, which directly probes the electroweak coupling of the top quark. The analysis uses 139 fb^{-1} of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. Requiring a photon with transverse momentum larger than 20 GeV and within the detector acceptance, the fiducial

Measurement of the Sensitivity of Two-Particle Correlations in pp Collisions to the Presence of Hard Scatterings

A key open question in the study of multiparticle production in high-energy pp collisions is the relationship between the "ridge"-i.e., the observed azimuthal correlations between particles in the underlying event that extend over all rapidities-and hard or semihard scattering processes. In particular, it is not known whether jets or their soft fragments are correlated with particles in the underl

Room to Grow and the Right to Say No: Theorizing the Liberatory Power of Peace in the Global South

This article builds on feminist and decolonial perspectives and engages with political geography literature to rethink the way that peace and violence are understood in the Global South. Building peace that is coherent with planetary and ecological limits and that does not further direct structural violence necessitates breaking with the extractivist model of development that benefits growth and a

Lättja : Det avslöjande avfallet

Den som slänger sitt skräp i närmaste gathörn eller dike gör sig skyldig till lättja. En harmlös förseelse kan tyckas, men sedd genom avfallshanteringens lins växer lättjan fort till en dödssynd som skadar andras liv och hälsa. Att gömma och glömma sopor har alltid varit en praktik som kan få ödesdigra konsekvenser. Tunnor med gift som grävs ner börjar förr eller senare läcka. Att skeppa avfall ti

Grain-level mechanism of plastic deformation in harmonic structure materials revealed by high resolution X-ray diffraction

Materials with heterogeneous microstructures have been reported to have an attractive combination of strength and ductility. This is attributed to synergistic strengthening effects from the difference in strength of fine- and coarse-grained regions. Understanding the interaction of the regions is crucial for further optimization of the microstructures. In this work, we fabricated nickel of harmoni

Correlating cathodoluminescence and scanning transmission electron microscopy for InGaN platelet nano-LEDs

Structural defects are detrimental to the efficiency and quality of optoelectronic semiconductor devices. In this work, we study InGaN platelets with a quantum well structure intended for nano-LEDs emitting red light and how their optical properties, measured with cathodoluminescence, relate to the corresponding atomic structure. Through a method of spectroscopy-thinning-imaging, we demonstra

Role of mitochondria in early molecular diagnosis and prognosis of cancer

Background:Earlier clinical detection of cancer may improve survival as well as offer opportunities for less invasive treatment options. This thesis explores whether the mitochondria and its related genes in the nuclear genome can be used as novel methods for the diagnosis and prognosis of cancers.Aims and Methods:Paper I: To investigate if mitochondrial dysfunction (characterized by mtDNA copy nu

Extractability, selectivity, and comprehensiveness in supercritical fluid extraction of seaweed using ternary mixtures of carbon dioxide, ethanol, and water

It is well-known that an ideal extraction method enabling quantitative analysis should give complete extraction of the target analytes as well as minimal co-extraction of unwanted matrix substances. If the extraction method is part of a nontarget screening protocol, the desired analytes can differ widely in terms of chemical properties. In chromatography, terminologies such as recovery, selectivit

Medborgarmedverkan i myndigheters sociala arbete : En hybridkonstruktion i gränslandet mellan institutionella logiker

I denna rapport redovisar Kerstin Svensson och Monica Larsson (Socialhögskolan, Lunds universitet) ett projekt som tar upp civilsamhällets medverkan i myndigheters arbete då privatpersoner engageras som socialt stöd för medmänniskor. Syftet med projektet är att förstå tanken bakom medborgarmedverkan i myndigheters lagreglerade sociala insatser, hur den har utvecklats och vilka tendenser som finns

Motivational currents in language learning : Frameworks for focused interventions

Building on Zoltán Dörnyei's authoritative work in the field of learner motivation, this book introduces a new conceptualization-Directed Motivational Currents (DMCs)-and sets out the defining aspects of what they are, what they are not, and how they are related to language learning motivation. Going beyond focused behavior in a single activity, DMCs concern intensive long-term motivation. The dis

Work integrated language learning : Boundary crossing, connectivity, and L2 affordances

In contexts of transnational migration, language skills provide the key to employability and successful integration into host country societies. To enhance the learning process, and facilitate transitions into the workforce, integrated programs of L2 learning have been developed in several Nordic countries. In these undertakings, language learning, vocational education, and workplace practice are
