Performance of a proton exchange membrane (PEM) fuel cell is very sensitive to its electric resistance appearing in its functional components. In this paper, the electric resistance as well as related parameters of a cell is evaluated by a recently developed numerical method in the through-plane direction of the electrodes. The results show that the channel/rib structure leads to non-homogeneous e
BACKGROUND: Perinatal stroke refers to a diverse but specific group of cerebrovascular diseases that occur between 20 weeks of fetal life and 28 days of postnatal life. Acute treatment options for perinatal stroke are limited supportive care, such as controlling hypoglycemia and seizures. Stem cell-based therapies offer a potential therapeutic approach to repair, restore, or regenerate injured bra
The cooperative emission of interacting nanocrystals is an exciting topic fueled by recent reports of superfluorescence and superradiance in assemblies of perovskite nanocubes. Several studies estimated that coherent coupling is localized to a small fraction of nanocrystals (10−7-10−3) within the assembly, raising questions about the origins of localization and ways to overcome it. In this work, w
Previous research has identified good communication as one of several key factors essential for destination resilience. However, there has been a lack of research on how communication contributes to this development. To address this gap, this study explores the communication work done by Destination Management Organizations (DMOs) with stakeholders to influence destination resilience. The study ex
The Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for very-high-energy (VHE) gamma-ray astronomy, with the deployment of tens of highly sensitive and fast-reacting Cherenkov telescopes. It will cover a wide energy range (20 GeV - 300 TeV) with unprecedented sensitivity. To maximize the scientific return, the observatory will be provided with an online softwar
Introduction: With the rapid development of treatment modalities for obesity management, there is a growing need for guidelines. This was acknowledged by the Swedish National Board of Health and Welfare and in 2020 the process of producing the first national guidelines for obesity care, including both children and adults, was initiated. The main aim was to ensure equal high standard care throughou
Here, we present new models to fit small angle X-ray scattering (SAXS) data for the characterization of ion tracks in polymers. Ion tracks in polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI) and polymethyl methacrylate (PMMA) were created by swift heavy ion irradiation using 197Au and 238U with energies between 185 MeV and 2.0 GeV. Transmission SAXS measurements were performe
Parkinson's disease (PD) is characterized by the loss of the dopaminergic nigrostriatal pathway which has led to the successful development of drug therapies that replace or stimulate this network pharmacologically. Although these drugs work well in the early stages of the disease, over time they produce side effects along with less consistent clinical benefits to the person with Parkinson's (PwP)
This chapter seeks to explore the intersections between occupational cultures, bystanders, and social justice and inclusion based on the empirical example of policing. Specifically, we pursue the question: what is the role of police officers as bystanders to occupational police culture and how does that influence inclusion? Against the backdrop of occupational culture, we put forth four key aspect
In this paper, we recall Lepowsky's and Wakimoto's product character formulas formulated in a new way by using arrays of specialized weighted crystals of negative roots for affine Lie algebras of type Cl(1), Dl+1(2) and A2l(2). Lepowsky–Wakimoto's infinite periodic products appear as one side of (conjectured) Rogers–Ramanujan-type combinatorial identities for affine Lie algebras of type Cl(1).
The European Union (EU) and the EU member states have adopted a number of policies that can support circular economy developments in the electrical and electronic equipment (EEE) sector, and additional policies have been proposed. The policies include the new Ecodesign Regulation and a new Battery Regulation, and forthcoming rules related to durability and repairability of mobile phones and tablet
This paper introduces a new lifting method for analyzing convergence of continuous-time distributed synchronization/consensus systems on the unit sphere. Points on the d-dimensional unit sphere are lifted to the (d+1)-dimensional Euclidean space. The consensus protocol on the unit sphere is the classical one, where agents move toward weighted averages of their neighbors in their respective tangent
With this paper and the accompanying audio paper, our aim is to explore the juxtaposition of sound and democracy. Recognizing the multifaceted nature of this field, we approach it through the notion of care and an empirical analysis of democratic implications of trying to regulate sound in public spaces. We examine standards as one example of the many attempts to control sound in both public and p
Cellular-based localization and sensing pave the way for a variety ofapplications across various domains, ranging from autonomous driv-ing to emergency care and intelligent traffic management. Althoughtraditional methods have been effective, they still face challenges such as therequirement for highly accurate models and the inherent complexity of thealgorithms. This thesis explores the potential
By measuring X-ray emission of the water molecule in liquid phase we establish a first example of K-shell X-ray emission spectra with strong breakdown of the molecular orbital picture. A complete splitting of the 2a1 peak into satellites is observed. A theoretical model with electronic configurations generated by coupled excitations/de-excitations, so-called semi-internal configuration interaction
Atmospheric inversions have been used for the past two decades to derive large-scale constraints on the sources and sinks of CO2 into the atmosphere. The development of dense in situ surface observation networks, such as ICOS in Europe, enables in theory inversions at a resolution close to the country scale in Europe. This has led to the development of many regional inversion systems capable of as
The serum metabolome contains a plethora of biomarkers and causative agents of various diseases, some of which are endogenously produced and some that have been taken up from the environment1. The origins of specific compounds are known, including metabolites that are highly heritable2,3, or those that are influenced by the gut microbiome4, by lifestyle choices such as smoking5, or by diet6.
