Objectives: Patients with acute type A aortic dissection (ATAAD) presenting with cerebral malperfusion have significantly poorer postoperative outcomes, making the decision whether to perform acute surgery difficult. The aim of this study was to investigate types of neurological symptoms and radiological findings and their association with permanent neurological injury and mortality following ATAA
Background: Obstetrical anal sphincter injuries are complications of vaginal birth that have the potential to cause substantial maternal morbidity. Predicting these injuries might help to improve maternal care as well as antenatal counseling and patient education. Previous attempts to create prediction models have in many cases involved variables only known postpartum, which limits their use in an
Background: The out-of-plane shear behavior of paperboards plays a critical role in converting processes such as creasing and folding. The recently proposed Split Double Cantilever Beam (SDCB) specimen has been used to characterize this behavior using a cohesive zone model, but its large size poses handling challenges. Objective: This study aims to optimize the SDCB specimen configuration to impro
Adverse childhood experiences (ACEs) can influence physical, cognitive and social development, impacting life outcomes including the child’s capacity to learn and become socially integrated. While steady relations to reliable, understanding adults may enhance child resilience and mitigate long-term effects on well-being, the difficulties of children with ACEs pose a challenge for school personnel.
Purpose: Indications for radiotherapy (RT) of the internal mammary nodes (IMN) in early breast cancer vary between countries. While studies indicate benefits, IMN RT increases the dose to the heart and lungs, and the risk-benefit ratio of this treatment is debated. This study investigates how IMN RT affects dose to organs at risk (OAR) and pneumonitis incidence in a clinical setting. Methods: This
Glycophospholipids combine the structural versatility of phospholipids and carbohydrates, but their potential as excipients and performance in other related applications remains largely unexplored due to their low natural abundance. We have synthesized four novel phosphatidyl saccharide conjugates with different carbohydrate head groups; glucose, galactose, fructose and xylose by using a Phospholi
Denna artikel undersöker hur innebörden av ekonomisk ersättning kan omdefinieras över tid i svenska familjehemsföräldrars liv. Med utgångspunkt i fyrtio kvalitativa intervjuer visar jag att familjehemsföräldrar initialt kan tona ned eller bortse från de ekonomiska aspekterna av uppdraget, men senare komma att vara beroende av denna inkomst – inte nödvändigtvis av egenintresse, utan som ett sätt atThis article examines how the meaning of financial compensation may be redefined over time in the lives of Swedish foster parents. Drawing on forty qualitative interviews, I demonstrate that while foster parents may initially downplay or disregard the monetary aspects of fostering, they can later come to depend on this income, not necessarily out of self-interest, but as a means of deepening their
The standard approach for visual place recognition is to use global image descriptors to retrieve the most similar database images for a given query image. The results can then be further improved with re-ranking methods that re-order the top scoring images. However, existing methods focus on re-ranking based on the same image descriptors that were used for the initial retrieval, which we argue pr
The performance of wireless communications at sea are often limited by fading caused by reflections at the sea surface. The reliability could potentially be improved by employing multiple antennas. We have conducted massive multiple-input multiple-output (MIMO) measurements at sea in order to evaluate the performance. The measurements were conducted at 5.6 GHz with 64 dual-polarized antennas, whic
—Capacitor chargers for pulsed power loads are typically realized as two-stage systems consisting of a front-end rectifier and a dclink filter followed by a dc/dc converter. Whereas such systems generally operate in constant current charging mode, it has recently been demonstrated that constant power charging may be achieved and can effectively eliminate line-side flicker. In this article, these i
This article examines the production of climate-related loss, specifically loss of access to land, among Indigenous and ethnic minority farming communities in northeastern Cambodia. We analyse how rapid socio-environmental and political-economic changes are eroding smallholder farmers' capacities to cope with climate impacts and can lead to what we call climate-related loss. We show how climate ch
This paper investigates the detection of permittivity defects in a fabricated, known object, motivated by a desire to detect errors in additively manufactured objects that may affect their electromagnetic performance. We use scattering parameter sensitivities to reconstruct the relative permittivity of a generic 2D object from microwave scattering measurements and a known reference model. To find
While numerous extraction methods have been applied to the brown algae Saccharina latissima, a systematic evaluation of how individual extraction parameters influence the extraction of each target polysaccharide has not previously been reported. Accordingly, this study compared conventional and advanced techniques for extracting fucoidan, laminarin, and alginate from pre-treated biomass. Conventio
With the abundance of data and digital traces of human behavior that are currently available, and the accessible algorithmic analyses to analyze them, management scholars have the opportunity to expand their scope of theoretical discovery and tackle increasingly complex management. However, we need additional elaboration on how algorithmic analysis can augment humans inference making, and how to b
