Staten har — inte minst med tanke på det förändrade omvärldsläget — god anledning att vara tydlig i kommunikationen, så att statens institutioner inte förväxlas med privata verksamheter. Detta gör att det rättsliga skyddet för statssymboler blir en viktigare fråga än tidigare. Men regelverket avseende svenska statssymboler och andra officiella symboler (såsom kommunvapen) är ganska svåröverskådlig
Combined quantum mechanics and molecular mechanics (QM/MM) calculations are a popular approach to study reaction mechanisms of enzymes. However, recently, the reproducibility of such calculations has been questioned, comparing the results of two software: NWChem and Q-Chem. Here, we continue and extend this study by including three additional software─ComQum, ORCA, and AMBER─using the same test ca
Deep metabarcoding offers an efficient and reproducible approach to biodiversity monitoring, but noisy data and incomplete reference databases challenge accurate diversity estimation and taxonomic annotation. Here, we introduce a novel algorithm, NEEAT, for removing spurious operational taxonomic units (OTUs) originating from nuclear-embedded mitochondrial DNA sequences (NUMTs) or sequencing error
A multi-variable adaptive controller is derived as the explicit solution to a minimax dynamic game. The minimizing player selects the control action as a function of past state measurements and inputs. The maximizing player selects disturbances and model parameters for the underlying linear time-invariant dynamics. This leads to a Bellman equation that can be solved explicitly for the case with un
A blood biomarker-based staging system for Alzheimer’s disease (AD) could improve the diagnosis, prognosis and identification of individuals most likely to benefit from specific therapies. Here, using targeted mass spectrometry, we measured six phosphorylated and six nonphosphorylated tau peptides in plasma from two independent cohorts: BioFINDER-2 and TRIAD (n = 689). We also analyzed the ratios
In the era of artificial intelligence of things (AIoT), distributed processing on local devices is growing in popularity. This stems from the need to reduce data transfer to and from central servers, with concerns about privacy and latency encouraging the processing of AI applications on edge devices. However, the computational demands of these applications require an increase in the processing ca
The number of degrees of freedom (NDoF) in a communication channel fundamentally limits the number of independent spatial modes available for transmitting and receiving information. Although the NDoF can be computed numerically for specific configurations using singular value decomposition (SVD) of the channel operator, this approach provides limited physical insight. In this paper, we introduce a
Model-based design is an emerging tool for dealing with the uncertain dynamic loads entering wastewater treatment plants (WWTPs). But our understanding about the load-driving population-dynamics is limited. Therefore, we studied if mobility data (mobile telecommunications data) could be used to reduce uncertainties during design. Mobility data from Uppsala, Sweden between 2019–2022 clearly quantif
Hur skapar man samsyn och samarbete i en kommunal koncern där förvaltningar tidigare tänkte i stuprör? I Höganäs växte en kultur av gemensamt ansvar fram genom vardagliga berättelser och budgetprocessen. Den här artikeln berättar historien om hur kommunen etablerade en koncernledningsgrupp för att styra sin samlade verksamhet. Eller var det egentligen en koncernkultur som växte fram?
Railways are vital for climate mitigation as a low-carbon mode of transport but must also be resilient to climate change impacts. This study explores dynamic adaptation strategies for coastal railway infrastructure in Sweden, focusing on Trelleborg. Stakeholder workshops informed adaptation pathways using a Dynamic Adaptive Pathways Planning Light (DAPP)-light approach, which enhances stakeholder
Although a great variety of strategies to suppress Li dendrite have been proposed for lithium metal batteries (LMBs), a deeper understanding of the factors playing a crucial role during extended electrochemical cycling is often lacking. Herein, the morphological reversibility of the Li-based anode for next-generation batteries under three prevalent strategies, i.e., the use of Li-Al alloys, polyme
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
PLCs are the core of most industrial automation systems (IAS). Modern IAS development emphasizes hardware unifica-tion and increased software significance. Remote PLC programming boosts efficiency by reducing time and travel costs, while supporting advanced training. Using safety controllers in the example of IAS, this paper presents hardware and PLC-specific software tools enabling remote PLC pro
RATIONALE: Caffeine is commonly used in preterm infants to improve respiratory function. However, the optimal strategies for caffeine initiation have not been defined. OBJECTIVES: To evaluate the relative benefits and harms of different indications and timings for caffeine initiation in preterm infants. SEARCH METHODS: We searched MEDLINE, Embase, CENTRAL, and trial registries up to 23 April 2025.
The package ParSeq is a Python software library for Parallel execution of Sequential data analysis. It implements a general analysis framework that consists of transformation nodes - intermediate stops along the analysis propagation to visualize data, display status and provide user input - and transformations that connect the nodes. ParSeq imports data into an adjustable data model - a collection
Putin kan välja att avsluta kriget i Ukraina – frågan är om han har råd med det. Fred är farligt, i alla fall om man är president i Ryssland. Och respekten för den som tappar makten försvinner snabbt. Att eskalera spänningar är därför en ren självbevarelsedrift. Ukraina är en huvudvärk för Putin, men den är inte hans värsta, skriver historikern Tomas Sniegon vid Lunds universitet.
