This special issue has invited scholars to reflect upon the theme of »grief« in the format of an audio paper. This format, we thought, would offer authors a possibility to present their research in sound, in a way that gives the theme of grief the opportunity to be heard firsthand, not only described in text. We, the editors, must admit that we prepared ourselves before listening to the audio manu
Hematopoietic stem cells (HSCs) enable hematopoietic stem cell transplantation (HCT) through their ability to replenish the entire blood system. Proliferation of HSCs is linked to decreased reconstitution potential, and a precise regulation of actively dividing HSCs is thus essential to ensure long-term functionality. This regulation becomes important in the transplantation setting where HSCs unde
Using renewable fuels is a reliable approach for decarbonization of combustion engines. iso-Butanol and n-butanol are known as longer chain alcohols and have the potential of being used as gasoline substitute or a renewable fraction of gasoline. The combustion behavior of renewable fuels in modern combustion engines and advanced combustion concepts is not well understood yet. Low-temperature combu
Background: Interactions between moss species in their earliest growth stages have received little attention. To what extent interspecific competition or priority effects influence spore germination, protonemal development and gametophore emergence is unknown. We evaluated such effects in pairwise interaction between six common bryophyte species: Atrichum undulatum, Bryum argenteum, Ceratodon pur
Background: The mercury isotopes around N=104 are a well-known example of nuclei exhibiting shape coexistence. Mixing of configurations can be studied by measuring the monopole strength ρ2(E0), however, currently the experimental information is scarce and lacks precision, especially for the Iπ→Iπ (I≠0) transitions. Purpose: The goals of this study were to increase the precision of the known branch
Researchers have shown a substantial amount of interest in smart tourism. Despite the fact that smart tourism has been a popular research topic in the tourism and hospitality industries over the past decade, research on this concept is still at a relatively early stage. This research extracted 50 studies (from 2015 to 2023) on the definition of smart tourism using a systematic review and performed
Inherent errors in tipping bucket flow meters may limit monitoring data reliability. In this work, we perform the static and dynamic calibration of four large tipping buckets, apply different regression curves and investigate the possible measurement error sources. The volumetric capacity (static calibration) of each piece of equipment was determined. They were tested (dynamic calibration) under t
We report the application of ancestral sequence reconstruction on coronavirus spike protein, resulting in stable and highly soluble ancestral scaffold antigens (AnSAs). The AnSAs interact with plasma of patients recovered from COVID-19 but do not bind to the human angiotensin-converting enzyme 2 (ACE2) receptor. Cryo-EM analysis of the AnSAs yield high resolution structures (2.6–2.8 Å) indicating
BackgroundObstructive sleep apnea (OSA) is a prevalent disorder and symptoms of nasal obstruction are highly prevalent in OSA. Treatment of nasal obstruction in OSA patients has shown modest and variable outcomes in reducing the apnea hypopnea index (AHI), but significant improvements in other indicators, such as sleep quality and daytime sleepiness as well as reductions in arousals have been obse
We carried out deep mapping observations of the atomic hydrogen (H i) 21 cm line emission in a field centered on the famous galaxy group Stephan's Quintet (SQ), using the Five-hundred-meter Aperture Spherical Telescope (FAST) equipped with a 19-beam receiver. The final data cube reaches an H i column density sensitivity of 5σ = 2.1 × 1017 cm-2 per 20 km s-1 channel with an angular resolution of 4.
Characteristic modes of arbitrary 2-D periodic systems are analyzed using scattering parameter data. This approach bypasses the need for periodic integral equations and allows for characteristic modes to be computed from generic simulation or measurement data. Example calculations demonstrate the efficacy of the method through comparison against a periodic method of moments (MoM) formulation for a
Background: Higher gluten intake in childhood is associated with increased incidence of celiac disease autoimmunity (CDA) and celiac disease. It remains to be studied whether different dietary patterns independent of gluten intake contribute to the incidence. Objectives: This study aimed to explore associations of dietary patterns by age 2 y with risk of CDA and celiac disease in genetically susce
This article focuses on Egyptian interpretations of the atomic bombings of Hiroshima and Nagasaki by the US at the end of the Second World War. It surveys the reactions and responses of influential thinkers between 1945 and 1951, a crucial period prior to decolonisation. The objective of this research is to capture a specific moment in time and understand how it shaped imaginations of the future.
We consider operator-valued differential Lyapunov and Riccati equations, where the operators B and C may be relatively unbounded with respect to A (in the standard notation). In this setting, we prove that the singular values of the solutions decay fast under certain conditions. In fact, the decay is exponential in the negative square root if A generates an analytic semigroup and the range of C ha
Atomic layer etching (ALE) is a cyclic technique based on self-limiting processes, such as reactive gas adsorption and material removal by low-energy ion bombardment 1,2. In a typical ALE process Ar+ ions with energies of 20-60 eV are used to desorb the reaction products, e.g. SiClx for the Si ALE. Compared to a corresponding continuous reactive ion etching (RIE), where the ion energies often exce
Background: Atopic dermatitis (AD) is a common inflammatory skin disease while the economic burden of AD by severity is not adequately understood. Objective: To estimate the societal economic burden and to identify cost determinants of AD. Methods: In this population-based, controlled cohort study in Sweden, patients with AD were identified through diagnosis codes in primary or secondary care or b
Debates about the gendered division of labour tend to focus on negotiation and decision-making by couples in the present, and assume that individuals make rational choices based on present circumstances when deciding questions about workforce engagement, domestic labour and childcare responsibilities. As a result, they overlook the fact that choices made in the present are shaped by past choices.
