Commissioning and operation status of the MAX IV 3 GeV storage ring vacuum system

The 3 GeV electron storage ring of the MAX IV laboratory is the first storage-ring-based synchrotron radiation facility with the inner surface of almost all the vacuum chambers along its circumference coated with non-evaporable getter (NEG) thin film. The coating provides a low dynamic outgassing rate and pumping of active gases. As the NEG coating was applied on an unprecedented scale, there were

A society ill-equipped to deal with the effects of climate change on cultural heritage and landscape : a qualitative assessment of planning practices in transport infrastructure

This paper provides insights into the handling of climate change issues related to cultural heritage at different government decision levels dealing with physical planning, and in particular roads. Data are derived from a qualitative analysis of official reports and interviews with local and regional planners in three Swedish regions with contrasting climates. The theoretical lens of Institutional

Long-term trends in income inequality: Winners and losers of economic change in Ghana, 1891–1960

This paper contributes to a growing literature on long-term trends and drivers of pre-industrial inequality by providing new stylized facts on the evolution of income inequality in Ghana from 1891 to 1960. Using newly constructed social tables, we estimate the Gini coefficient for seven consecutive decades at a time in which the adoption and expansion of cocoa cultivation transformed the Ghanaian

Decontamination of food packages from SARS-COV-2 RNA with a cold plasma-assisted system

The accidental contamination of food and food packaging surfaces with SARS-CoV-2 is of increasing concern among scientists and consumers, particularly in relation to fresh foods that are consumed without further cooking. The use of chemical sanitizers is often not suitable for these kinds of commodities; therefore, a non-thermal sanitation technology could help to increase safety in relation to th

Evaluation of the Forsvall biopsy needle in an ex vivo model of transrectal prostate biopsy–a novel needle design with the objective to reduce the risk of post-biopsy infection

Background: Transrectal prostate biopsy (TRbx) transfers colonic bacteria into prostatic tissue, potentially causing infectious complications, including sepsis. Our objective was to determine whether biopsy needle shape, surface properties and sampling mechanism affect the number of bacteria transferred through the colon wall, and evaluate a novel needle with improved properties. Methods: The stan

Microwave scan and brain biomarkers to rule out intracranial hemorrhage : study protocol of a planned prospective study (MBI01)

Purpose: The aim of this planned study is to evaluate the ability of a cranial microwave scanner in conjunction with nine brain biomarkers (Aβ40, Aβ42, GFAP, H-FABP, S100B, NF-L, NSE, UCH-L1 and IL-10) to detect and rule out traumatic intracranial hemorrhage in an emergency department setting. Traumatic brain injury is a world-wide topic of interest for researchers and clinicians. It affects 2% of

Effect of divider wall-to-end wall distance on the vortical structures and heat transfer characteristics of two-pass channel using topological analysis

Purpose: This study aims to explore the 3 D separated flow fields and heat transfer characteristics at the end wall of a serpentine channel with various turn clearances using topological analysis and critical points principles of three-dimensional vortex flow. Design/methodology/approach: This aims to explore the 3 D separated flow fields and heat transfer characteristics at the end wall of a serp

Unpacking the politics of legislative debates

Legislative debates are a thriving field in comparative politics. They make representation work by offering legislators the opportunity to take the floor and represent their constituents. In this paper, we review the key theoretical concepts and empirical findings in a maturing field. We begin by addressing what legislative debates are and why we should study them to learn about inter- and intra-p

Unconventional sources of error in high-resolution wide-swath SAR systems based on scan-on-receive

The scan-on-receive (SCORE) is a key digital beamforming (DBF) technique for future high-resolution wide-swath synthetic aperture radar (SAR) systems. A sharp and high gain receive beam, steered in real time towards the expected direction of arrival (DoA) of the backscattering signal, allows for improved SAR imaging performance with respect to a conventional approach. Nevertheless, it also exposes

Comparing machine learning-derived global estimates of soil respiration and its components with those from terrestrial ecosystem models

The CO2 efflux from soil (soil respiration (SR)) is one of the largest fluxes in the global carbon (C) cycle and its response to climate change could strongly influence future atmospheric CO2 concentrations. Still, a large divergence of global SR estimates and its autotrophic (AR) and heterotrophic (HR) components exists among process based terrestrial ecosystem models. Therefore, alternatively de

Roadmap on dynamics of molecules and clusters in the gas phase

Abstract: This roadmap article highlights recent advances, challenges and future prospects in studies of the dynamics of molecules and clusters in the gas phase. It comprises nineteen contributions by scientists with leading expertise in complementary experimental and theoretical techniques to probe the dynamics on timescales spanning twenty order of magnitudes, from attoseconds to minutes and bey

Myocardial infarction in diffuse large B-cell lymphoma patients – a population-based matched cohort study

Background: The outcome for diffuse large B-cell lymphoma (DLBCL) patients has improved with the immunochemotherapy combination R-CHOP. An increased rate of heart failure is well documented following this treatment, whereas incidence and outcome of other cardiac complications, for example myocardial infarction, are less well known. Method: We identified 3548 curatively treated DLBCL patients in Sw

Subclinical hyperthyroidism is associated with increased risk of vertebral fractures in older men

Summary: In elderly men included in MrOS-Sweden, subclinical hyperthyroidism (SHyper) was markedly associated with increased risk of vertebral fractures. Introduction: Overt hyperthyroidism is associated with increased risk of fractures. However, only a few studies have investigated whether SHyper is associated with fracture risk in elderly men. We therefore investigated if SHyper was a risk facto

Six transiting planets and a chain of Laplace resonances in TOI-178

Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the fragility of their orbital configuration ensures that no significant scattering or collisional event has taken place since the earliest formation phase when the parent protoplanetary disc was still present. In this cont

Scrotal Calcinosis Treated with Carbon Dioxide Laser : Two Cases and a Short Literature Review

Scrotal calcinosis (SC) is a rare and benign condition characterized by multiple, calcified, usually asymptomatic, nodules in the scrotal skin (1). SC often appears in adolescence or early adulthood and may cause embarrassment (1, 2). The standard therapeutic approach is surgical excision of the affected skin (3, 4). We report here 2 cases of SC treated successfully with carbon dioxide (CO2) laser

Whole cell recognition of staphylococcus aureus using biomimetic SPR sensors

Over the past few decades, a significant increase in multi-drug-resistant pathogenic microorganisms has been of great concern and directed the research subject to the challenges that the distribution of resistance genes represent. Globally, high levels of multi-drug resistance represent a significant health threat and there is a growing requirement of rapid, accurate, real-time detection which pla

Nudging healthcare professionals in clinical settings : a scoping review of the literature

BACKGROUND: Healthcare organisations are in constant need of improvement and change. Nudging has been proposed as a strategy to affect people's choices and has been used to affect patients' behaviour in healthcare settings. However, little is known about how nudging is being interpreted and applied to change the behaviour of healthcare professionals (HCPs). The objective of this review is to ident

Reduced repetition suppression in aging is driven by tau-related hyperactivity in medial temporal lobe

Tau deposition begins in the medial temporal lobe (MTL) in aging and Alzheimer's disease (AD), and MTL neural dysfunction is commonly observed in these groups. However, the association between tau and MTL neural activity has not been fully characterized. We investigated the effects of tau on repetition suppression, the reduction of activity for repeated stimulus presentations compared to novel sti

Lack of Opsonic Antibody Responses to Invasive Infections With Streptococcus dysgalactiae

Introduction: Streptococcus dysgalactiae can cause severe recurrent infections. This study aimed to investigate antibody responses following S. dysgalactiae bacteraemia and possible development of protective immunity. Materials and Methods: Patients with S. dysgalactiae bacteraemia in the county of Skåne between 2017 and 2018 were prospectively included. Acute and convalescent sera were obtained.

New and Practical Formulation for Overlaps of Bogoliubov Vacua

In this Letter, we present a new expression for the overlaps of wave functions in Hartree-Fock-Bogoliubov based theories. Starting from the Pfaffian formula by Bertsch et al. [1], an exact and computationally stable formula for overlaps is derived. We illustrate the convenience of this new formulation with a numerical application in the context of the particle-number projection method. This new fo
