The modelling of filtered chemical source terms remains a fundamental challenges for large eddy simulation (LES) of reacting flows, such as combustion. This study investigates various scale similarity models for predicting filtered reaction rates. The theoretical foundation of scale similarity models is reviewed, and several extensions and generalisations are proposed. These include the distinctio
This study examines carbon (C) and water dynamics in two East African dryland ecosystems: a savanna rangeland grazed by livestock and wildlife, and a rainfed cropland under minimal tillage. Over 185 days, both systems were showed a similar magnitude of C emissions with differing temporal patterns. The rangeland showed fluctuating C exchange, with losses followed by increased C uptake after rainfal
Quantitative data are needed to constrain the feedback loops between vegetation and hydroclimate. In this study, the amplitudes of variations in the triple oxygen isotope composition of water at the soil-plant-atmosphere interface are measured in savanna and dry forest contexts in West Africa (Benin and Senegal). Comparison of in situ data and model estimates reveals the following: (a) The value o
Understanding and managing charge carrier recombination dynamics is crucial for optimizing the performance of metal halide perovskite optoelectronic devices. In this work, we introduce a machine learning-assisted intensity-modulated two-photon photoluminescence microscopy approach for quantitatively mapping recombination processes in MAPbBr3 perovskite microcrystalline films at micrometer-scale re
This study introduces the concept of Collective Permanent Supportive Housing (CPSH), tailored for older adults with histories of homelessness and long-term substance use. CPSH offers residents individual apartments and secure tenures, using a harm reduction approach. The study, being designed to identify the benefits and risks of CPSH, was based on (i) a quantitative dataset with a national survey
We present the CH4 and N2O budgets for anthropogenic and natural sources and sinks of Australasia (Australia and New Zealand) from 2010 to 2019 using bottom-up and top-down methods, in line with the RECCAP-2 initiative, with extensions to 2022. We show that the bottom-up CH4 budget for Australasia (2010–2019) was a net source of 14.1 ± 5.5 Tg CH4 yr−1, with Australia and New Zealand contributing 8
We explore the phenomenological consequences of a model with an extended scalar sector, incorporating strongly coupled inert Higgs doublets. The model introduces three Higgs doublets: one that interacts with the SU(2) symmetry of the Standard Model, and two inert doublets belonging to a strongly interacting sector, embedded in the SU(2)2 × SU(2)1 × U(1)Y electroweak gauge symmetry. This symmetry s
Collective action by small-scale farmers can contribute significantly toward rural development. One important aspect that remains relatively neglected, especially in research set in Africa, is the role of farmer collectives in political processes. We study the local-level dynamics of a farmer-based organization mobilizing for agroecology and food sovereignty in Uganda. Through qualitative, collabo
This chapter explains vital elements in the salutogenic model of health and how these fit into the inner core of health promotion expressed in the Ottawa Charter for Health Promotion. Salutogenesis, is here considered as a theory, a life orientation and as the sense of coherence. In line with the salutogenic theory, health is described as a process in an ease/dis-ease continuum, defined as the mov
Recent measurements of event-by-event fluctuations of multistrange baryons and kaons in proton–proton collisions by ALICE have been proposed as sensitive probes to distinguish between thermal and string-based hadronization mechanisms. We demonstrate that two key observables – the normalized net-Ξ second-order cumulant and the net-K–net-Ξ Pearson correlation coefficient – can be re-expressed in ter

This paper presents the results from a qualitative study with Swedish researchers in the social sciences and the humanities. The aim of the study was to explore researchers’ perceptions of ethical review (i.e. the pros and cons of the system) and to what extent the system of ethical review could possibly be reformed to better accommodate research in the social sciences and the humanities. To this
Climate warming is expected to influence the prevalence of vector-transmitted parasites. Understanding the extent to which this is ongoing, or has already occurred, requires empirical data from populations monitored over long periods of time, but these studies are sparse. Further, vector-disease research involving human health is often influenced by disease control efforts that supersede natural t
The efficient computation of color-summed QCD amplitudes at high parton multiplicities remains a central challenge for precision collider predictions. Existing approaches using trace, color-flow, or adjoint bases suffer from non-orthogonality, which complicates the color algebra and scales poorly with multiplicity. In this work, we present an off-shell recursive framework for computing all-gluon t

Background/Objectives: Undergoing intensive cancer treatment, such as allogeneic haematopoietic stem cell transplantation, challenges the entire life situation of patients and their family caregivers. A prerequisite for effective care is that interventions are tailored to the unique circumstances of each individual. The aim of this study was to examine the feasibility of a developed person-centred
Forests play a crucial role in Europe’s strategy for achieving carbon neutrality. Carbon turnover time - the time that carbon spends in the ecosystem - is a fundamental component in determining forest potential to mitigate climate change. However, there is a significant knowledge gap regarding how current and future forest management practices will affect carbon turnover time. This study aims to c
