A Deep View into the Nucleus of the Sagittarius Dwarf Spheroidal Galaxy with MUSE. II. Kinematic Characterization of the Stellar Populations

The Sagittarius dwarf spheroidal galaxy is in an advanced stage of disruption but still hosts its nuclear star cluster (NSC), M54, at its center. In this paper, we present a detailed kinematic characterization of the three stellar populations present in M54: Young metal-rich (YMR); intermediate-age metal-rich (IMR); and old metal-poor (OMP), based on the spectra of 6500 individual M54 member stars

Decreased prevalence of Moraxella catarrhalis in addition to Streptococcus pneumoniae in children with upper respiratory tract infection after introduction of conjugated pneumococcal vaccine : a retrospective cohort study

Objectives: To study effects of the introduction of pneumococcal conjugate vaccines (PCV) on the interspecies dynamics of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis in preschool children with respiratory tract infection. Methods: Nasopharyngeal samples from children aged ≤6 years with upper respiratory tract infection (n = 14 473) in South Sweden were analysed durin

Days absent from work as a result of complications associated with type 2 diabetes : Evidence from 20 years of linked national registry data in Sweden

Aims: To analyse days absent from work related to individual microvascular, macrovascular and other complications of type 2 diabetes (T2D) and to identify key drivers of absence. Materials and methods: National health and socio-economic individual-level data were analysed for the years 1997 to 2016 for people with T2D, and age-, sex- and residential region-matched controls (5:1) using linkage to S

Morphology Modulation of Ionic Surfactant Micelles in Ternary Deep Eutectic Solvents

Deep eutectic solvents (DES) are potentially greener solvents obtained through the complexation of simple precursors which, among other applications, have been investigated in recent years for their ability to support the self-assembly of amphiphilic molecules. It is crucial to understand the factors which influence surfactant solubility and self-assembly with respect to the interaction of the sur

Variation and trends in reasons for knee replacement revision : a multi-registry study of revision burden

Background and purpose — Studies describing time-related change in reasons for knee replacement revision have been limited to single regions or institutions, commonly analyze only 1st revisions, and may not reflect true caseloads or findings from other areas. We used revision procedure data from 3 arthroplasty registries to determine trends and differences in knee replacement revision diagnoses. P

Loss and damage : A review of the literature and directions for future research

Climate change researchers argue that a residual domain exists beyond the limits of adaptation to prevent deleterious climate change impacts: this has been labeled as “loss and damage.” Over the last 8 years, there has been significant growth in loss and damage scholarship thus making it imperative to take stock of what we know already and directions for future research. We undertook a quantitativ

The role of platelets in sepsis

A State of the Art lecture titled “The role of platelets in sepsis” was presented at the ISTH congress in 2020. Sepsis is a life-threatening organ dysfunction caused by a dysregulated and multifaceted host response to infection. Platelets play a significant role in the coordinated immune response to infection and therefore in the inflammation and coagulation dysfunction that contributes to organ d

Medial temporal atrophy in preclinical dementia : Visual and automated assessment during six year follow-up

Medial temporal lobe (MTL) atrophy is an important morphological marker of many dementias and is closely related to cognitive decline. In this study we aimed to characterize longitudinal progression of MTL atrophy in 93 individuals with subjective cognitive decline and mild cognitive impairment followed up over six years, and to assess if clinical rating scales are able to detect these changes. Al

Australian Bogong moths Agrotis infusa (Lepidoptera : Noctuidae), 1951–2020: decline and crash

The Bogong moth Agrotis infusa is well known for its remarkable long-distance migration – a return journey from the plains of southeast Australia to the Australian Alps – as well as for its cultural significance for Indigenous Australians. Each Spring, as many as four billion moths are estimated to arrive in the Australian Alps to aestivate in cool mountain caves and in boulder fields, bringing wi

Incidence of distal radius fracture in a general population in southern Sweden in 2016 compared with 2001

Summary: In this population-based study, we compared the incidence of distal radius fracture in 2016 with that in the same region’s adult general population in 2001 using radiographs to identify fracture cases. We showed that the incidence decreased by 24% in 2016 compared with 2001 indicating an important development. Introduction: We conducted an epidemiological study on residents of northeaster

Experiences of participation in supervised group exercise among pregnant women with depression or low psychological well-being : A qualitative descriptive study

Objective: To explore experiences with supervised group exercise during pregnancy in women with depression or low psychological well-being. Design: A qualitative descriptive study based on semi-structured, individual, in-depth interviews analyzed by means of thematic analysis. Setting: The Department of Obstetrics, Rigshospitalet, Copenhagen University Hospital, Denmark. Participants: Through a pu

The social context of nearest neighbors shapes educational attainment regardless of class origin

We study the association between sociospatial neighborhood conditions throughout childhood and educational attainment in adulthood. Using unique longitudinal microdata for a medium-sized Swedish town, we geocode its population at the address level, 1939 to 1967, and link individuals to national registers, 1968 to 2015. Thus, we adopt a long-term perspective on the importance of nearby neighbors du

Impact of α-synuclein pathology on transplanted hESC-derived dopaminergic neurons in a humanized α-synuclein rat model of PD

Preclinical assessment of the therapeutic potential of dopamine (DA) neuron replacement in Parkinson's disease (PD) has primarily been performed in the 6-hydroxydopamine toxin model. While this is a good model to assess graft function, it does not reflect the pathological features or progressive nature of the disease. In this study, we establish a humanized transplantation model of PD that better

Confronting experimental data with heavy-ion models : Rivet for heavy ions

The Rivet library is an important toolkit in particle physics, and serves as a repository for analysis data and code. It allows for comparisons between data and theoretical calculations of the final state of collision events. This paper outlines several recent additions and improvements to the framework to include support for analysis of heavy ion collision simulated data. The paper also presents

Local structure and magnetism of Fe2O3 maghemite nanocrystals : The role of crystal dimension

Here we report on the impact of reducing the crystalline size on the structural and magnetic properties of γ-Fe2O3 maghemite nanoparticles. A set of polycrystalline specimens with crystallite size ranging from ~2 to ~50 nm was obtained combining microwave plasma synthesis and commercial samples. Crystallite size was derived by electron microscopy and synchrotron powder diffraction, which was used

Evolution and structure of technological systems - An innovation output network

The mechanisms responsible for the structure and evolution of technological systems are not fully understood. This study examines the network of supply and use of significant innovations across industries in Sweden, 1970-2013. The results suggest that at least 30% of innovation patterns can be statistically predicted by network stimulus from both backward and forward linkages in the Swedish econom

Herwig 7.2 release note

A new release of the Monte Carlo event generator Herwig (version 7.2) is now available. This version introduces a number of improvements over the major version 7.0, notably: multi-jet merging with the dipole shower at LO and NLO QCD; spin correlations in both the dipole and angular-ordered parton showers; an improved choice of evolution variable in the angular-ordered parton shower; improvements t

Bone mineral as a drug-seeking moiety and a waste dump a Review

Bone is a dynamic tissue with a quarter of the trabecular and a fifth of the cortical bone being replaced continuously each year in a complex process that continues throughout an individual’s lifetime. Bone has an important role in homeostasis of minerals with non-stoichiometric hydroxyapatite bone mineral forming the inorganic phase of bone. Due to its crystal structure and chemistry, hydroxyapat

Warmer climate projections in EC-Earth3-Veg : The role of changes in the greenhouse gas concentrations from CMIP5 to CMIP6

Climate projections for the 21st century for CMIP6 are warmer than those for CMIP5 despite nominally identical instantaneous radiative forcing. Many climate modeling groups attribute the stronger warming in the CMIP6 projections to the higher climate sensitivity of the new generation of climate models, but here we demonstrate that also changes in the forcing datasets can play an important role, in
