This paper explores the prevalent themes across multiple threads on the popular Swedish discussion forum Flashback. Among its diverse array of topics, the forum actively engages users in addressing and debating questions pertaining to COVID-19 vaccines and vaccination. Through distinguishing between positive and negative perspectives within posts across 14 relevant thread discussions, we employ BE

An impact at Chicxulub, Mexico, occurred 66 million years ago, producing a global stratigraphic layer that marks the boundary between the Cretaceous and Paleogene eras. That layer contains elevated concentrations of platinum-group elements, including ruthenium. We measured ruthenium isotopes in samples taken from three Cretaceous-Paleogene boundary sites, five other impacts that occurred between 3

The Neumann–Neumann method is a commonly employed domain decomposition method for linear elliptic equations. However, the method exhibits slow convergence when applied to semilinear equations and does not seem to converge at all for certain quasilinear equations. We therefore propose two modified Neumann–Neumann methods that have better convergence properties and require fewer computations. We pro

Background: Irradiation with violet-blue light (VBL), in the spectrum of 405–450 nm, has been reported to be effective against pathogenic bacteria. Aim: To investigate whether VBL irradiation could reduce the level of surface contamination at seven shared patient bathrooms in two wards at a hospital in Sweden. Methods: Repeated sampling of five separate surfaces (door handle, tap water handle, flo

Two major sociopolitical challenges loom over the development of carbon removal. One is mitigation deterrence: that research and deployment of carbon removal could delay mitigation efforts. The other is environmental and climate justice — in particular that carbon removal will be developed in ways that further environmental racism, e.g. for the benefit of interests and groups in the global North w

Objectives Investigating men's perceived lifetime risk of prostate cancer. Design Survey-based study to men invited for prostate-specific antigen (PSA) screening in the GÖTEBORG-2 trial between September 2015 and June 2020. Setting 38 775 men in the Gothenburg area, Sweden, were invited for PSA-Testing and participated in a survey. Participants 17 980 men participated in PSA-Testing, of whom 13 18

Background: Radiostereometric analysis (RSA) provides highly accurate data about the migration of a total knee arthroplasty (TKA) component. However, patient-reported outcome measures (PROMs) reflect the patients' perspective of their functional status, pain, and overall health after TKA. The aim of this study was to evaluate the association between tibial implant migration and change in postopera

Sampling rare events in proteins is crucial for comprehending complex phenomena like cryptic pocket opening, where transient structural changes expose new binding sites. Understanding these rare events also sheds light on protein-ligand binding and allosteric communications, where distant site interactions influence protein function. Traditional unbiased molecular dynamics simulations often fail t

This article is about finding the limit set for banded Toeplitz matrices. Our main result is a new approach to approximate the limit set Λ(b), where b is the symbol of the banded Toeplitz matrix. The new approach is geometrical and based on the formula Λ(b) = ∩ρ∊(0, ∞) sp T (bρ), where ρ is a scaling factor, i.e., bρ(t):= b(ρt), and sp(∙) denotes the spectrum. We show that the full intersection ca

A range of derivatives of an iridium pincer complex with a bis-trifluoromethyl-substituted ligand have been studied to determine how their properties differ from those of similar systems. The emphasis is on derivatives valuable for catalytic acceptorless dehydrogenation, including intermediates and deactivation products. The studies highlight small but important differences in the electron richnes

In the adult murine brain, neural stem cells (NSCs) can be found in two main niches: the dentate gyrus (DG) and the subventricular zone (SVZ). In the DG, NSCs produce intermediate progenitors (IPs) that differentiate into excitatory neurons, while progenitors in the SVZ migrate to the olfactory bulb (OB), where they mainly differentiate into inhibitory interneurons. Neurogenesis, the process of ge

Iridium dioxide (IrO2), ruthenium dioxide (RuO2), and their solid solutions (Ir1-xRuxO2) are very active electrocatalysts for the oxygen evolution reaction (OER). Efficient and facile synthesis of nanosized crystallites of these materials is of high significance for electrocatalytic applications for converting green energy to fuels (power-to-X). Here, we use in situ X-ray scattering to examine rea

A rare sighting of two male carrion specialist dung beetles, Scarabaeolus carniphilus Deschodt & Davis, 2015, burying a freshly dead Herald snake (Crotaphopeltis hotamboeia (Laurenti, 1768)) is documented from its discovery in the field and subsequent reburial under laboratory conditions. The species studied is a member of the telecoprid (dung roller) Scarabaeini, but behaved here like a parac

Objective: To study associations of clinical characteristics and treatment choice with functional outcome, mortality, and time to death in a national sample of aneurysmal subarachnoidal hemorrhage patients. Methods: Data were extracted from a prospective nationwide multicenter study performed in September 2014 to March 2018. Glasgow Outcome Scale Extended (GOSE) grade, 1-year mortality, and surviv

Near-haploidization, that is, loss of one copy of most chromosomes, is a relatively rare phenomenon in most tumors, but is enriched among certain soft tissue sarcomas, including undifferentiated pleomorphic sarcoma (UPS). Presumably, near-haploidization can arise through many mechanisms. This study aimed to identify gene rearrangements that could cause near-haploidization. We here present two UPS

The chapter examines what peace looks like from the working levels of the Nordic countries. Several researchers have proclaimed a common Nordic approach to peace and conflict resolution “dead”. However, through interviews focusing on the working level, we find that the Nordics in fact work very closely together in practice, especially in the field in conflict-affected areas. This work is generally

Proteomics can shed light on the dynamic and multifaceted alterations in neurodegenerative disorders like Alzheimer’s disease (AD). Combining radioligands measuring β-amyloid (Aβ) plaques and tau tangles with cerebrospinal fluid proteomics, we uncover molecular events mirroring different stages of AD pathology in living humans. We found 127 differentially abundant proteins (DAPs) across the AD spe
