Lessons from the African Union Mission for Somalia (AMISOM) for peace operations in Mali

Mali and Somalia have both suffered determined Islamist-inspired insurgencies, and in both African Union-led peace operations have been a central pillar in political and security stabilization efforts. Despite challenges in transferring lessons between unique situations, the AMISOM experience can offer some useful lessons for Mali. We have identified several themes that helped to drive success for

Light-flavor particle production in high-multiplicity pp collisions at s= 13 TeV as a function of transverse spherocity

Results on the transverse spherocity dependence of light-flavor particle production (π, K, p, ϕ, K*0, KS0, Λ, Ξ) at midrapidity in high-multiplicity pp collisions at s = 13 TeV were obtained with the ALICE apparatus. The transverse spherocity estimator SOp categorizes events by their azimuthal topology. Utilizing narrow selections on SOp, it is possible to contrast particle production in collision

A Model of Froth Flotation with Drainage : Simulations and Comparison with Experiments

The model of the operation of a froth flotation column is described by a nonlinear convection–diffusion partial differential equation that incorporates the solids–flux, and drift–flux theories as well as a model of foam drainage. The resulting model is novel and contains non-standard ingredients such as discontinuous fluxes and degenerating diffusion accounting for foam drainage. It predicts the b

From Sound to Structure : Robust Localization of Sources, Sensors, and Surroundings

The topic of this thesis is how to infer geometric information using sound data. Achieving this requires solving several subproblems. First, signal processing of the recorded sound is needed to compute measurements of primitive geometric relations. Secondly, robust estimation is needed to go from primitive geometric measurements to more useful higher-level information such as the locations of micr

Boosting catalytic performance of ternary FeCoNi yolk-shelled nanoreactors for organic reactions via low-content active metal decoration

Nanoreactors have attracted extensive research and attention in the field of catalysis due to their unique surface/interface structures and physicochemical properties. However, conventional nanoreactors have limited catalytic performance due to the confinement of their active components in the “nanochamber”. Herein, low-content active metal (AM, AM = Pd, Cu) decorated yolk-shelled FeCoNiOx (AM/FeC

Efficient near-field ptychography reconstruction using the Hessian operator

X-ray ptychography is a powerful and robust coherent imaging method providing access to the complex object and probe (illumination). Ptychography reconstruction is typically performed using first-order methods due to their computational efficiency. Higher-order methods, while potentially more accurate, are often prohibitively expensive in terms of computation. In this study, we present a mathemati

Two-particle pseudorapidity correlations in sqrt(s) = 13 TeV proton-proton collisions measured with ALICE

This thesis investigates two-particle pseudorapidity correlations in proton-proton collisions at sqrt(s)=13 TeV at the ALICE detector at the Large Hadron Collider. The primary focus is on the calculation of the correlation function in pseudorapidity across different multiplicity classes and charge combinations. Subsequently, efficiency corrections were applied and studied within Monte Carlo simula

Swedish abroad: Motivation to learn, access and use Swedish among university-level learners in Poland

The motivation to learn foreign languages is diminishing globally due to the dominance of English in business, media, and education, and additionally to the access it provides to the so-called global community and global identity. Nevertheless, smaller languages such as Swedish continue to be offered at universities worldwide, with students enrolling despite their limited societal use. This study

Haematological malignancies in systemic sclerosis : a population-based nationwide register study

Objectives (1) To assess the risk of haematological malignancies in individuals with systemic sclerosis (SSc) compared with individuals without SSc; (2) to explore how the risk varies across groups stratified by sex and age; and (3) to determine when these malignancies present in relation to SSc diagnosis in a population-based setting. Methods We performed a nationwide cohort study using high-qual

Hund’s flat band in a frustrated spinel oxide

Electronic flat bands associated with quenched kinetic energy and heavy electron mass have attracted great interest for promoting strong electronic correlations and emergent phenomena such as high-temperature charge fractionalization and superconductivity. Intense experimental and theoretical research has been devoted to establishing the rich nontrivial metallic and heavy fermion phases intertwine

Search for electroweak production of supersymmetric particles in final states with two τ-leptons in s = 13 TeV pp collisions with the ATLAS detector

Three searches for the direct production of τ-sleptons or charginos and neutralinos in final states with at least two hadronically decaying τ-leptons are presented. For chargino and neutralino production, decays via intermediate τ-sleptons or W and h bosons are considered. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of 139 fb−1, recorded with the ATLAS de

Local food and sustainable regional development

This paper examines municipality-owned sustainable and local food production initiatives in Dalarna, Sweden, through the lens of the ‘public plate’ as both a strategy for securing high-quality, sustainable food and a tool for regional development. Using a qualitative case study, we explore how these initiatives promote local food while advancing broader sustainability goals. We situate local actio

A lignosulfonate-based negolyte for aqueous redox flow batteries

Aqueous redox flow batteries (RFBs) as grid-scale energy storage devices hold great potential to accomodate the rising demand for intermittent renewable energy sources. A significant parameter that enhances the sustainability of RFBs is selecting the appropriate redox species. In this study, we investigated the application of lignosulfonate as a redox species for the negolyte of aqueous RFBs becau

Metabolite Profiles of Heart Failure, Central Hemodynamic Derangement, and Response to Heart Transplantation

BACKGROUND: Heart failure (HF) is characterized by hemodynamic derangements that are likely to mediate systemic metabolic perturbations but limited data are available. Plasma metabolite profiling provides opportunities for comprehensive investigation of such perturbations. Here, we aimed to characterize plasma profiles that associate with HF and their relationship with central hemodynamics, sympto

Dissecting FAP+ Cell Diversity in Pancreatic Cancer Uncovers an Interferon-Response Subtype of Cancer-Associated Fibroblasts with Tumor-Restraining Properties

Within the stroma of pancreatic ductal adenocarcinoma (PDAC), mesenchymal cells differentiate into cancer-associated fibroblast (CAF) subtypes that differentially mediate disease progression. Defining the regulatory mechanism and diversity of CAF subtypes could identify potential therapeutic strategies to harness the tumor-suppressive activities of CAFs. To address this, we utilized single-cell RN

Analysis of emissions reduction, spatial distribution, and reaction pathways of NOx during MILD combustion of biomass gasification gas

Biomass gasification gas (BGG), a carbon-neutral renewable fuel and important hydrogen carrier, holds significant promise for sustainable energy systems. However, its practical implementation is challenged by combustion instability and elevated NOx emissions, primarily due to localized high-temperature zones induced by the hydrogen content. MILD (Moderate or Intense Low-oxygen Dilution) combustion

Paul Ricoeur: Empowering Education, Politics and Society, by Alison Scott-Baumann (Review article)

Alison Scott–Baumann’s Paul Ricoeur: Empowering Education, Politics and Society employs Ricoeur’s philosophy to unpack contemporary universities’ struggles with polarisation and activism. Though short in form, this rich critical study illuminates how universities understand themselves and why fostering dialogue around disagreements and controversies can enable more inclusive, empowered academic co
