Collective motion in a sheet of microswimmers
Self-propelled particles such as bacteria or algae swimming through a fluid are non-equilibrium systems where particle motility breaks microscopic detailed balance, often resulting in large-scale collective motion. Previous theoretical work has identified long-ranged hydrodynamic interactions as the driver of collective motion in unbounded suspensions of rear-actuated (“pusher”) microswimmers. In
Time-resolved measurement and simulation of a longitudinal single-bunch instability at the MAX IV 3 GeV ring
The study and understanding of collective effects plays a vital role for fourth-generation light sources. These effects mostly need to be mitigated and controlled to achieve the design operational parameters. However, they can also be utilized to gain insights into the properties of the machine. While the 3 GeV storage ring at the MAX IV light source is running in multi-bunch mode during user oper
Bounding the Amount of Entanglement from Witness Operators
We present an approach to estimate the operational distinguishability between an entangled state and any separable state directly from measuring an entanglement witness. We show that this estimation also implies bounds on a variety of other well-known entanglement quantifiers. This approach for entanglement estimation is then extended to both the measurement-device-independent scenario and the ful
Simulation studies on longitudinal beam dynamics manipulated by corrugated structures under different bunch length conditions at KARA
In the KIT storage ring KARA (Karlsruhe Research Accelerator), two parallel plates with periodic rectangular corrugations are planned to be installed. These plates will be used for impedance manipulation to study and eventually control the electron beam dynamics and the emitted coherent synchrotron radiation (CSR). In this contribution, we present simulation results showing the influence of differ
Development and content validity testing of a colonoscopy-specific patient-reported experience measure : the Patient Experience Colonoscopy Scale (PECS)
Background: In endoscopic care, favourable patient experiences before, during and after a colonoscopy are essential for the patient’s willingness to repeat the procedure. To ensure that significant experiences are measured, patients should be involved in creating the measurement instruments. Thus, the aim of the present study was to develop a colonoscopy-specific PREM by (1) operationalising patie
Beam Dynamics of the Transparent Injection for the MAX IV 1.5 GeV Ring
Following the successful operation of the Multipole Injection Kicker (MIK) in the MAX IV 3 GeV storage ring, we plan to introduce a similar device in the MAX IV 1.5 GeV ring. In order to assess the effectiveness of such device and to define its working parameters, we performed a series of studies aimed at understanding the beam dynamics related to the injection process. In this paper we describe t
Improved Emittance and Brightness for the MAX IV 3 GeV Storage Ring
At MAX IV Laboratory, the Swedish Synchrotron Radiation (SR) facility, the largest of two rings operates at 3 GeV with a bare lattice emittance of 330 pm rad. Upgrade plans are under consideration aiming at a gradual reduction of the emittance, in three stages: a short-term with an emittance reduction of 20% to 40%, a mid-term with an emittance reduction of more than 50% and a long-term with an em
2021 European Resuscitation Council/ European Society of Intensive Care Medicine Algorithm for Prognostication of Poor Neurological Outcome After Cardiac Arrest—Can Entry Criteria Be Broadened?
OBJECTIVES: To explore broadened entry criteria of the 2021 European Resuscitation Council/European Society of Intensive Care Medicine (ERC/ ESICM) algorithm for neuroprognostication including patients with ongoing sedation and Glasgow Coma Scale-Motor score (GCS-M) scores 4–5. DESIGN: Retrospective multicenter observational study. SETTING: Four ICUs, Skane, Sweden. PATIENTS: Postcardiac arrest pa
Interplay of socioeconomic status, cognition, and school performance in the ABCD sample
Coming from a disadvantaged background can have negative impact on an individual’s educational trajectory. Some people however seem unaffected and cope well with the demands and challenges posed by school education, despite growing up in adverse conditions, a phenomenon termed academic resilience. While it is uncertain which underlying factors make some people more likely to circumvent unfavorable
European consumer price indices since 1870
Artikeln presenterar en databas med förmodligen de mest aktuella och tillförlitliga konsumentprisindexen (KPI) för ett stort urval av europeiska länder sedan 1870. Databasen utgör i huvudsak en sammanställning av existerande index men är ett bidrag genom att gå tillbaka till ursprungliga eller ignorerade källor. För vissa länder, där KPI saknats, konstrueras nya provisoriska index och vissa index This article presents a database with the probably most up-to-date and reliable consumer price indices for a large sample of European countries since 1870. The database is a compilation but a contribution by going back to original or ignored works. For some countries, where CPIs have been missing, new provisional indices are constructed, and some are reconstructed for critical periods. The article
SUMO-specific proteases : SENPs in oxidative stress-related signaling and diseases
Oxidative stress is employed to depict a series of responses detrimental to normal cellular functions resulting from an imbalance between intracellular oxidants, mainly reactive oxygen species and antioxidant defenses. Oxidative stress often contributes to the development of various diseases, including cancer, cardiovascular diseases, and neurodegenerative diseases. In this process, the relationsh
Ruthenium NNN-Based Pincer Complexes with Metal Ligand Cooperation as Catalysts for N-Methylation of Anilines and Nitroarenes with Methanol as a C1 Source
A novel phosphine-free ruthenium pincer complex based on an NNN pincer ligand has been prepared and fully characterized. The complex was subsequently employed as an efficient catalyst for the N-methylation of amines and the direct N-methylation of nitroarenes using methanol as a C1 source under mild reaction conditions following the borrowing-hydrogen approach. Both of the catalytic transformation

Optimal Transport Based Impulse Response Interpolation in the Presence of Calibration Errors
Acoustic impulse responses (IRs) are widely used to model sound propagation between two points in space. Being a point-to-point description, IRs are generally estimated based on input-output pairs for source and sensor positions of interest. Alternatively, the IR at an arbitrary location in space may be constructed based on interpolation techniques, thus alleviating the need of densely sampling th

Low CD4 + T cell count is related to specific anti-nuclear antibodies, IFNα protein positivity and disease activity in systemic lupus erythematosus pregnancy
Background: Lymphopenia, autoantibodies and activation of the type I interferon (IFN) system are common features in systemic lupus erythematosus (SLE). We speculate whether lymphocyte subset counts are affected by pregnancy and if they relate to autoantibody profiles and/or IFNα protein in SLE pregnancy. Methods: Repeated blood samples were collected during pregnancy from 80 women with SLE and 51
Adaptation to water-induced disaster : exploring local knowledge and Indigenous knowledge-led strategies
The magnitude of water-induced disasters is projected to increase in the coming decades. Yet, there is a substantial gap in the understanding of how local knowledge and Indigenous knowledge are employed to respond to climate change water-induced disasters. We examine this gap through a meta-review of literature published between 2014 and 2019 yielding 39 scholarly papers. The meta-review indicates
