Confirmed reinfection with SARS-CoV-2 during a pregnancy : A case report

Pregnancy might impact immunity after SARS-CoV-2 infection and/or vaccination. We describe the first case of reinfection with SARS-CoV-2 during a pregnancy. While the mother lacked detectable antibodies 2 months after the first infection, both mother and baby had IgG antibodies at delivery. Infection did not cause any adverse pregnancy outcome.

Hardware Accelerator of Bundle Adjustment Algorithm

With the popularization and development of CV technology, the SLAM algorithm is widely used in scenarios such as self-driving cars and autonomous navigation robots. As a key step in the SLAM system, the BA algorithm is responsible for optimizing camera parameters and 3D point coordinates. BA obtains more accurate estimates by shrinking the re-projection error. So as to support the SLAM system

Search for boosted diphoton resonances in the 10 to 70 GeV mass range using 138 fb −1 of 13 TeV pp collisions with the ATLAS detector

A search for diphoton resonances in the mass range between 10 and 70 GeV with the ATLAS experiment at the Large Hadron Collider (LHC) is presented. The analysis is based on pp collision data corresponding to an integrated luminosity of 138 fb −1 at a centre-of-mass energy of 13 TeV recorded from 2015 to 2018. Previous searches for diphoton resonances at the LHC have explored masses down to 65 GeV,

GWAS of random glucose in 476,326 individuals provide insights into diabetes pathophysiology, complications and treatment stratification

Conventional measurements of fasting and postprandial blood glucose levels investigated in genome-wide association studies (GWAS) cannot capture the effects of DNA variability on ‘around the clock’ glucoregulatory processes. Here we show that GWAS meta-analysis of glucose measurements under nonstandardized conditions (random glucose (RG)) in 476,326 individuals of diverse ancestries and without di

Spatial reorientation by geometry in bumblebees

Human and non-human animals are capable of using basic geometric information to reorient in an environment. Geometric information includes metric properties associated with spatial surfaces (e.g., short vs. long wall) and left-right directionality or 'sense' (e.g. a long wall to the left of a short wall). However, it remains unclear whether geometric information is encoded by explicitly computing

bioRad : biological analysis and visualization of weather radar data

Weather surveillance radars are increasingly used for monitoring the movements and abundances of animals in the airspace. However, analysis of weather radar data remains a specialised task that can be technically challenging. Major hurdles are the difficulty of accessing and visualising radar data on a software platform familiar to ecologists and biologists, processing the low-level data into prod

Why the European Commission’s ‘pragmatic’ approach to asylum is not enough: Re-imagining solidarity as a new form of conducting regional politics

The failure of the EU and its Member States to adequately respond to increased refugee movements since 2015, has caused disagreement on how the principle of solidarity and fair sharing of responsibility should be given effect in the context of a reformed European policy on migration. In September 2020, theEuropean Commission proposed the new Pact on Migration and Asylum which was meant to promote

Human B cells

The importance of B cells and their critical role in the maintenance of health through generation of antibody-mediated immune protection is undoubted. However, the differences between the responses of B cells with different surface phenotypes in different microanatomical sites as well as diversity in B-cell function outside antibody production are just starting to be acknowledged and resolved. Thi

Testing Abstractions for Cyber-Physical Control Systems

Control systems are ubiquitous and often at the core of Cyber-Physical Systems, like cars and aeroplanes. They are implemented as embedded software, that interacts in closed loop with the physical world through sensors and actuators. As a consequence, the software cannot just be tested in isolation. To close the loop in a testing environment and root causing failure generated by different parts of

The twin-arginine translocation system is vital for cell adhesion and uptake of iron in the cystic fibrosis pathogen Achromobacter xylosoxidans

BackgroundAchromobacter xylosoxidans is an emerging pathogen that causes airway infections in patients with cystic fibrosis. Knowledge of virulence factors and protein secretion systems in this bacterium is limited. Twin arginine translocation (Tat) is a protein secretion system that transports folded proteins across the inner cell membranes of gram-negative bacteria. Tat has been shown to be impo

Bioactive Suture with Added Innate Defense Functionality for the Reduction of Bacterial Infection and Inflammation

Surgical site infections (SSI) are a clinical and economic burden. Suture-associated SSI may develop when bacteria colonize the suture surface and form biofilms that are resistant to antibiotics. Thrombin-derived C-terminal peptide (TCP)-25 is a host defense peptide with a unique dual mode of action that can target both bacteria and the excessive inflammation induced by bacterial products. The pep

Bemötande av patienter som har intellektuell funktionsnedsättning med nedsatt kommunikationsförmåga

Bakgrund: Intellektuell funktionsnedsättning (IF) är en utvecklingsneurologisk funktionsnedsättning med brister i kognition och nedsatt adaptiv förmåga. Orsaken kan bero på ärftlighet, kromosomförändring, sjukdom eller skada i hjärnan. Patienter med IF har ofta nedsatt kommunikationsförmåga och är ofta beroende av personer runtomkring som kan tolka behoven. En del av distriktssköterskors ansvar är

Energy in the Transportation System - A comparison of charging infrastructure scenarios

A functioning charging infrastructure is crucial for achieving full-scale national electrification within the transport sector. The system is likely to consist of different charging technologies, all with the main objective of providing efficient energy replenishment services. Careful planning for the deployment of this infrastructure is of high importance. The consumer segments are diverse, each

Critical masculine and feminine norms in sustainable municipal transport policies and planning

Transport planning has historically been dominated by masculinity norms with minimal attention to sustainability, but these norms are challenged. Our analytical framework explores municipal solutions to sustainable transport that go beyond traditional norms and advances knowledge on how gendered sustainability norms are articulated in municipal transport policies and planning documents. The articl

Pharmacological modulation of vascular ageing: a review from VascAgeNet

Vascular ageing, characterized by structural and functional changes in blood vessels of which arterial stiffness and endothelial dysfunction are key components, is associated with increased risk of cardiovascular and other age-related diseases. As the global population continues to age, understanding the underlying mechanisms and developing effective therapeutic interventions to mitigate vascular

Generalized anxiety disorder (GAD) in children and adolescents

Children with generalized anxiety disorder (GAD) are often described by their parents or teachers as "little adults, " in part because of the seemingly adult-like themes that populate their child's worries; for example, the health of family members or family finances and concerns about performance. Younger children may experience more vague worries of "something" bad happening to themselves, famil
