Promoting responsible practices in international research collaboration in a multipolar landscape
Over the last few years, just as the COVID-19 pandemic has illustrated the growing need for open international collaboration, increasing geopolitical tensions and politicization of research are leading to higher barriers for transnational scientific cooperation. These deteriorating conditions for inclusive cooperation may hamper both the general advancement of knowledge and, more pointedly, our ab
Effect of artificial light on activity in frugivorous bats (Pteropodidae)
Artificial lighting at nights (ALAN) affects behaviour in many animals, especially nocturnal species. However, its effect on frugivorous bats remains less explored, especially in the family Pteropodidae. Since they rely predominantly on vision and light-based cues, ALAN at roost sites could have consequences on their behaviour, activity, and the ecosystem services they provide. In a semi-urban sit
3D analysis and grading of calcifications from ex vivo human meniscus
Objective: Meniscal calcifications are associated with the pathogenesis of knee osteoarthritis (OA). We propose a micro-computed tomography (μCT) based 3D analysis of meniscal calcifications ex vivo, including a new grading system. Method: Human medial and lateral menisci were obtained from 10 patients having total knee replacement for medial compartment OA and 10 deceased donors without knee OA (
On the almost-circular symplectic induced Ginibre ensemble
We consider the symplectic-induced Ginibre process, which is a Pfaffian point process on the plane. Let N be the number of points. We focus on the almost-circular regime where most of the points lie in a thin annulus (Formula presented.) of width (Formula presented.) as (Formula presented.). Our main results are the bulk scaling limits of all correlation functions near the real axis, and also away
Extreme solar particle storms and links to solar activity inferred from cosmogenic radionuclides in ice cores
During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. The first directly observed solar storm was the Carrington event in 1859 which is linked to disruptions of the tel
Cerebrospinal Fluid Biomarkers of Synaptic Dysfunction Are Altered in Parkinson's Disease and Related Disorders
Background: Synaptic dysfunction and degeneration are central contributors to the pathogenesis and progression of parkinsonian disorders. Therefore, identification and validation of biomarkers reflecting pathological synaptic alterations are greatly needed and could be used in prognostic assessment and to monitor treatment effects. Objective: To explore candidate biomarkers of synaptic dysfunction

The genetic regulation of protein expression in cerebrospinal fluid
Studies of the genetic regulation of cerebrospinal fluid (CSF) proteins may reveal pathways for treatment of neurological diseases. 398 proteins in CSF were measured in 1,591 participants from the BioFINDER study. Protein quantitative trait loci (pQTL) were identified as associations between genetic variants and proteins, with 176 pQTLs for 145 CSF proteins (P < 1.25 × 10−10, 117 cis-pQTLs and 59

Triboelectric biometric signature
Biometric signatures based on either the physiological or behavioural features of a person have been widely used for identification and authentication. However, few strategies have been developed that combine the two types of features in one signature. Here, we report a type of biometric signature based on the triboelectricity of the human body (TEHB) that combines these two types of features. Thi
Signal-to-noise ratio optimization in X-ray fluorescence spectrometry for chromium contamination analysis
In most cases, direct X-ray fluorescence (XRF) analysis of solutions entails technical difficulties due to a high X-ray scattering background resulting in a spectrum with a poor signal-to-noise ratio (SNR). Key factors that determine the sensitivity of the method are the energy resolution of the detector and the amount of scattered radiation in the energy range of interest. Limiting the width of t

In this study, we discuss Swedish travelers from different backgrounds during their visits to Greece and Asia Minor in the 18th century. Besides their scientific interests, they write about their impressions of the Greeks and other people in the area, as well as education, language, religion, local economy, culture, and social life. They have good knowledge of ancient Greek history and the Greek l
Full-field X-ray fluorescence imaging with a straight polycapillary X-ray collimator
Due to the availability of X-ray imaging detectors, full-field X-ray fluorescence (FF-XRF) imaging technique has become achievable, which provides an alternative to scanning X-ray fluorescence imaging with a micro-focus X-ray beamline. In this paper, we present a setup based on straight capillary optics and an energy-dispersive hybrid pixel detector, which can perform simultaneous mapping of sever
Människan i maskinen. RoboCop (1987) som samhällskritik och profetia
Den alltjämt pågående övergången från analoga, mekaniska format och apparater till en nära nog allomfattande digital teknologi utmärks av långtgående och omfattande förändringar. Föga förvånande benämns omvandlingsprocessen återkommande som den tredje industriella revolutionen. Sedan det sena 1990-talet har digital teknik även kommit att alltmer prägla film- och tv-inspelningar, men de nya möjligh
På dragande kall och ämbetes vägnar : En vänskrift till Ingegerd Christiansson
Ingegerd Christiansson har gått i pension och med denna skrift vill vi visa vår uppskattning för hennes fina insatser vid Historiska institutionen. Ingegerd har verkat som administratör under flera decennier. Som lokalt skyddsombud vid institutionen och centralt huvudskyddsombud vid Humanistiska och teologiska fakulteterna har hon dessutom gjort mycket viktiga insatser för arbetsmiljöarbetet. I de
