Decays of Ξb− and Ωb− baryons to Λc+h−h′− final states, with h−h′− being π−π−, K−π− and K−K− meson pairs, are searched for using data collected with the LHCb detector. The data sample studied corresponds to an integrated luminosity of 8.7 fb−1 of pp collisions collected at centre-of-mass energies s = 7, 8 and 13 TeV. The products of the relative branching fractions and fragmentation fractions for

The evolution of human adaptations across diverse geographical regions has been shaped by dynamic interplays between environmental demands and cultural evolution throughout millennia. During the Pleistocene epoch, cultural variations were relatively uniform globally, harmonizing with the Ice Age climate that created vast analogous environments. At the end of the Late Pleistocene—the start of the H

This essay examines the Bavarian physician, mining engineer, and Catholic romantic philosopher Franz von Baader's (1765-1841) enigmatic claim that we think because we are thought with the help of the moral theologian Servain Pinckaers OP (1925-2008) and the psychologist Mihaly Csikszentmihalyi (1934-2021). Using Pinckaers' idea of 'fontal knowledge' and Csikszentmihalyi's notion of flow, I interprThis essay examines the Bavarian physician, mining engineer, and Catholic romantic philosopher Franz von Baader's (1765-1841) enigmatic claim that we think because we are thought with the help of the moral theologian Servain Pinckaers OP (1925-2008) and the psychologist Mihaly Csikszentmihalyi (1934-2021).

Recent years have seen an increase in reports on rising wildfire occurrences in countries of the Middle East. Wildfires are integral parts of terrestrial ecosystems and as such prone to the recent, large-scale anthropogenic changes of global ecosystem dynamics. However, the systematic analysis of patterns of wildfire occurrences – fire regimes – is concentrated on a few well studied regions and re

Behovet av förnybar energi är stort och förväntas öka i framtiden. I Sverige står vattenkraft för en betydande andel av elproduktionen, där anläggningarna ofta innebär fysiska hinder för vandringsberoende fiskarter. För att bibehålla elproduktionen och samtidigt säkerställa god konnektivitet i vattendragen krävs väl fungerande migrationslösningar förbi kraftverken, både för uppströmsvandrande och The need for renewable energy is substantial and is expected to increase in the future. In Sweden, hydropower accounts for a significant portion of the energy production, with facilities often presenting physical barriers to migratory fish species. To maintain electricity production while ensuring good connectivity in watercourses, effective migration solutions past the power plants are required f

Background/Aim: Anterior resection is the gold standard surgery for high and middle rectal tumors. In cases where anterior resection is not feasible, the surgeon resorts to a non-restorative approach such as Hartmann’s procedure or abdominoperineal resection. It is not well studied how Hartmann’s procedure impacts quality of life. This cross-sectional cohort study compares the long-term quality of

In this thesis we performed a pooled cohort study to investigate the role of radiomics in head and neck cancer prognosis. The aim was to investigate prognostic value for overall survival and cancer recurrence of radiomics combined with previously studied demographic and clinical risk factors. Radiomics features were extracted from the gross tumor volume on a computed tomography captured prior to r

A search is presented for the pair production of higgsinos χ˜ in gauge-mediated supersymmetry models, where the lightest neutralinos χ˜1 0 decay into a light gravitino G˜ in association with either a Higgs h or a Z boson. The search is performed with the ATLAS detector at the Large Hadron Collider using 139 fb−1 of proton–proton collisions at a centre-of-mass energy of s=13TeV. It targets final st

The rise of business angel groups represents a shift in the early-stage financing landscape. This thesis examines the heterogeneity and dynamics of angel groups, focusing on two interconnected research questions: (1) How do financial capital, locus of decision-making, and formalization influence exit strategies within angel groups? and (2) How do angel groups leverage their collectiveresources to

Color perception has been a traditional test-case of Whorf ’s principle of linguistic relativity (Whorf, 1940/1956), which states that speakers of different languages evaluate perceptual contrasts differently, influenced by language-specific partitions of reality. Early empirical studies showed that speakers of Zuni, a language that does not lexically separate the colors ‘orange’ and ‘yellow’ but ins

The following thesis seeks to explore the role of myth-making and securitisation in the United Kingdom’s ontological security and identity formation, as seen in their discourses surrounding security and the normalisation of far-right imaginaries and sentiments. It uses the United Kingdom as a case study in lieu of studying the larger phenomena of how national identity has been framed in security d

A search for the nonresonant production of Higgs boson pairs in the Formula Presented channel is performed using Formula Presented of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. The analysis strategy is optimized to probe anomalous values of the Higgs boson self-coupling modifier Formula Presented and of the quarti

Walrus ivory was a prized commodity in medieval Europe and was supplied by Norse intermediaries who expanded across the North Atlantic, establishing settlements in Iceland and Greenland. However, the precise sources of the traded ivory have long remained unclear, raising important questions about the sustainability of commercial walrus harvesting, the extent to which Greenland Norse were able to c
