We propose a novel class of dark matter (DM) candidates in the form of a heavy composite axionlike particle (ALP) with highly suppressed electromagnetic interactions populating vast yet unexplored domains in the ALP parameter space. This is achieved for the first time in the simplest dark confining gauge theory yielding a new composite glueball ALP (GALP) DM coupling-mass relation found in terms o
Circular economy (CE) is both contesting the status quo and a contested idea, for which many competing understandings and implementations exist. And yet, analyses of the role of social conflicts and pluralism are rare in the CE literature, overly focused on convergence and cooperation. To address this research gap, we draw on Mouffe’s “agonistic pluralism” political theory. Empirically, the study
Cutaneous endometriosis is a rare manifestation of endometriosis, and few reports on its dermoscopic features have been published. In this case report, we present a 40-year-old female with cutaneous endometriosis arising in a caesarean scar, exhibiting unique and distinct dermoscopic features. Te patient presented with a nodular, papillomatous growth in the right end of the scar, and dermoscopic e
Repair entails the fixing of one or several specific malfunctions or performance issues in order to return a product to proper condition or functioning. Issues requiring repair can be cosmetic (e.g., a scratch or dent), functional (e.g., the product does not turn on), or both (e.g., the product’s screen is broken). For every product that is successfully repaired instead of replaced, the need to ma
Alternative Economic Models (AEMs) are theoretical frameworks that, if implemented, could fundamentally transform economic systems by aligning financial objectives with sustainability goals. Conducting rigorous research on future-oriented AEMs and other complex sustainability systems presents challenges, particularly due to the exploration of largely unverifiable future possibilities. Qualitative
Background: Current guidelines for the treatment of severe TBI recommend maintaining a cerebral perfusion pressure (CPP) at 60–70 mmHg. In our institution, as well as others, an alternative algorithm—originally named the Lund concept—has been used. This treatment algorithm employs metoprolol and clonidine to limit CPP, accepting levels below 60 mmHg, with the aim of reducing cerebral edema. Previo
This paper addresses the path-tracking problem of time-optimal trajectories under model uncertainties, by proposing a real-time predictive scaling algorithm. The algorithm is formulated as a convex optimization problem, designed to balance the trade-off between improving feasibility and time optimality of a trajectory. The predicted trajectory is scaled based on the presence of path segments that
Currently, the European Union (EU) is the “green leader”, globally, in adopting policies to support longer product lifetimes. One reason for this state of affairs is that EU Member States are adopting progressive policies, which put pressure on the EU to set EU-wide laws to replace national ones. The main reason for this situation is that national rules may lead to distortions in trade in the EU S
Layered transition metal dichalcogenides (TMDs) are model systems to investigate the interplay between superconductivity and the charge density wave (CDW) order. Here, we use muon spin rotation and relaxation (μ+SR) to probe the superconducting ground state of polycrystalline 2H-TaS2, which hosts a CDW transition at 76 K and superconductivity below 1 K. The μ+SR measurements, conducted down to 0.2
Telomere length (TL) early in life often shows high heritability and may predict telomere shortening later in life and life expectancy. Yet, there is limited data about what influences TL and TL change at early developmental stages. It is debated whether early-life TL is determined at conception or shaped by early environmental conditions. Here, we investigate whether TL and telomere shortening ar
Over geologic time, biocalcification – the process by which marine organisms make calcium carbonate (CaCO3) – has reshaped climates, ocean life, and seawater chemistry. In particular, the evolution of coccolithophores, the largest group of nannoplankton and today’s most productive calcifiers, transformed ocean environments and the carbon cycle. Their origins, however, remain enigmatic. This is par
Background: In axial spondyloarthritis (axSpA), 5–10% of patients have comorbid inflammatory bowel disease (IBD). Beyond that, 50–60% display histologic inflammation in ileum/colon biopsies, and fecal calprotectin (F-calprotectin) is elevated in relation to healthy controls. Prior studies have shown such, often subclinical, gut inflammation in axSpA to be associated with more active disease, as me
Due to the lower radiative fraction and typically higher storage pressures, gas temperatures can often result in longer safety distances compared to radiative heat transfer for hydrogen jet flames. The high temperatures, however, also lead to a low density causing the flow to rise at a certain distance from the release. Unfortunately, a model to determine this distance, similar to what is availabl
