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 (

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

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

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

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

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

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

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

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

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

A large amount of contaminated cellulose and wood fibers were emitted directly onto the seabed by the pulp and paper industry before the year of 1970. This fiber-rich sediment contains concentrations of hazardous substances that cause environmental problems. Mercury (Hg) in the fiber sediment is a worldwide threat because it can bioaccumulate in the aquatic ecosystem and eventually affect human he

With the rapid expansion of the waste incineration business both in Europe and globally, there is a growing need for the elemental analysis for fly ash from municipal solid waste incineration. In this work, samples of washed and unwashed ash from municipal solid waste incineration in Sundsvall are evaluated. Qualitative analysis and semi-quantitative analysis are used to compare two elemental anal
