On strong shift equivalence for row-finite graphs and C*-algebras
We extend and strengthen a theorem of Bates that says that row-finite graphs that are strong shift equivalent have Morita equivalent graph C*-algebras. This allows us to ask whether our stronger notion of Morita equivalence does in fact characterise strong shift equivalence. We believe this will be relevant for future research on infinite graphs and their C*-algebras. We also study in-splits and o
Secondary Ice Production - current state of the science and recommendations for the future
Measured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>−10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has long been proposed that a secondary ice production process must exist that is able to rapidly enhance the number concentration of the ice population following initial primary ice

Saccadic body turns in walking Drosophila
Drosophila melanogaster structures its optic flow during flight by interspersing translational movements with abrupt body rotations. Whether these "body saccades" are accompanied by steering movements of the head is a matter of debate. By tracking single flies moving freely in an arena, we now discovered that walking Drosophila also perform saccades. Movement analysis revealed that the flies separ
Neuroligins Nlg2 and Nlg4 Affect Social Behavior in Drosophila melanogaster
The genome of Drosophila melanogaster includes homologs to approximately one-third of the currently known human disease genes. Flies and humans share many biological processes, including the principles of information processing by excitable neurons, synaptic transmission, and the chemical signals involved in intercellular communication. Studies on the molecular and behavioral impact of genetic ris
Critical time window of neuronal cholesterol synthesis during neurite outgrowth
Cholesterol is an essential membrane component enriched in plasma membranes, growth cones, and synapses. The brain normally synthesizes all cholesterol locally, but the contribution of individual cell types to brain cholesterol metabolism is unknown. To investigate whether cortical projection neurons in vivo essentially require cholesterol biosynthesis and which cell types support neurons, we have
Therapy of Pelizaeus-Merzbacher disease in mice by feeding a cholesterol-enriched diet
Duplication of PLP1 (proteolipid protein gene 1) and the subsequent overexpression of the myelin protein PLP (also known as DM20) in oligodendrocytes is the most frequent cause of Pelizaeus-Merzbacher disease (PMD), a fatal leukodystrophy without therapeutic options. PLP binds cholesterol and is contained within membrane lipid raft microdomains. Cholesterol availability is the rate-limiting factor
Framing : The Social Art of Influence
From back cover: "A smart, incisive toolkit for understanding how the framing of information influences the way we see the world.In today's chaotic media landscape, working out who and what to believe is a daunting task. Lies and misinformation are only part of the problem - often the way a story is presented has just as much effect on us as what the story is.In Framing, sociologist Mikael Klintma

Evaluation of ANN model for pipe status assessment in drinking water management
Non-revenue water due to pipe leakages presents a significant global challenge, impacting both the economy and environmental sustainability. The current approach to pipe management for water utilities in Sweden is mainly reactive; leaks are repaired when detected, sometimes with large costs if the leakage is extensive and critical. With this study, we want to focus on proactive pipe network manage
Drivers and Barriers for “Circular” Consumer Electronics in the European Union
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

A comparative study of fatigue and processing speed in patients with multiple sclerosis treated with natalizumab or rituximab
Background: Fatigue is the most debilitating symptom in patients with multiple sclerosis (MS). Natalizumab and rituximab are the most used MS disease modifying therapies in Sweden, but comparative data on the effect on fatigue is sparse. Objective: Primary objective was to compare fatigue levels between patients on natalizumab and rituximab. As secondary objective, we assessed processing speed, an
Chiroptical Second-Harmonic Tyndall Scattering from Silicon Nanohelices
Chirality is omnipresent in the living world. As biomimetic nanotechnology and self-assembly advance, they too need chirality. Accordingly, there is a pressing need to develop general methods to characterize chiral building blocks at the nanoscale in liquids such as water─the medium of life. Here, we demonstrate the chiroptical second-harmonic Tyndall scattering effect. The effect was observed in

Discrete spectrum of the magnetic Laplacian on almost flat magnetic barriers
The magnetic Laplacian with a step magnetic field has been intensively studied during the last years. We adapt the construction introduced by Bonnaillie-Noël et al. [Bull. London Math. Soc. 56, 2529 (2024)] to prove the existence of bound states of a new effective operator involving a magnetic step field on a domain with an almost flat magnetic barrier. This result emphasizes the fact that even a
COMBAT-MS : A Population-Based Observational Cohort Study Addressing the Benefit–Risk Balance of Multiple Sclerosis Therapies Compared with Rituximab
Objective: To assess comparative effectiveness, safety, and tolerability of off-label rituximab, compared with frequently used therapies approved for multiple sclerosis (MS). Methods: A Swedish cohort study of persons with relapsing–remitting MS, age 18 to 75 years at inclusion and with a first therapy start or a first therapy switch between 2011 and 2018. Low-dose rituximab was compared with MS-a
