The impact of previous health on the mortality after aneurysmal subarachnoid hemorrhage : analysis of a prospective Swedish multicenter study

Purpose: There is an an increasing awareness of the importance of health and lifestyle for stroke diseases like spontaneous subarachnoid hemorrhage (SAH). However, the importance of pre-existing medical conditions for clinical course and mortality after SAH has not been studied. The aim of the present study was to identify pre-existing conditions contributing to mortality after SAH. Methods: Data

Participatory future visions of collaborative agroecological farmer-pastoralist systems in Tanzania

Agroecology is increasingly promoted as a way to create just and sustainable farm- and food systems. Although there are multiple initiatives to scale up agroecology, current socio-political structures often hinder its potential to transform food systems. This study uses participatory approaches to create paintings that envision agroecological futures in the context of increased farmer-pastoralist

Pipeline Infrastructure Required to Meet the Requirements on AI

The theme of this issue is infrastructure as code (IaC). This concept typically refers to the application of software engineering practices in managing deployment infrastructure. Moving from physical hardware to virtual machines using configuration files that are way more flexibleâ€Â"and they can be version controlled and distributed. As such, IaC paves the way for automation and DevOps. This col

Long-term calcium imaging reveals functional development in hiPSC-derived cultures comparable to human but not rat primary cultures

Models for human brain-oriented research are often established on primary cultures from rodents, which fails to recapitulate cellular specificity and molecular cues of the human brain. Here we investigated whether neuronal cultures derived from human induced pluripotent stem cells (hiPSCs) feature key advantages compared with rodent primary cultures. Using calcium fluorescence imaging, we tracked

Immunoglobulin germline gene polymorphisms influence the function of SARS-CoV-2 neutralizing antibodies

The human immunoglobulin heavy-chain (IGH) locus is exceptionally polymorphic, with high levels of allelic and structural variation. Thus, germline IGH genotypes are personal, which may influence responses to infection and vaccination. For an improved understanding of inter-individual differences in antibody responses, we isolated SARS-CoV-2 spike-specific monoclonal antibodies from convalescent h

8-band k · p modeling of strained InxGa(1-x)As/InP heterostructure nanowires

An 8-band k · p theory is implemented for studying the electronic properties of near-surface lateral InxGa(1-x)As/InP heterostructure nanowires in the (100) direction. The change in bandgap and effective mass due to inhomogeneous strain are compared to unstrained scenario nanowires, and the lattice mismatch is varied from -3.2% to 1%. The nanowires' height is H = 5, 13 nm, and the width varies fro

Flicker Explained : guide to IEC for the lighting industry

Flicker, or more precisely temporal light modulation (TLM), has re-emerged as a problem with the introduction of LED-based lighting technology. TLM, meaning variations in light intensity over time, may have negative effects on human health, causing annoyance, headaches, eyestrain and migraine. In addition to the unnecessary suffering TLM causes in individuals, the negative consequences of TLM crea

Whole-genome Analysis Reveals Contrasting Relationships Among Nuclear and Mitochondrial Genomes Between Three Sympatric Bat Species

Understanding mechanisms involved in speciation can be challenging, especially when hybridization or introgression blurs species boundaries. In bats, resolving relationships of some closely related groups has proved difficult due subtle interspecific variation both in morphometrics and molecular data sets. The endemic South American Histiotus bats, currently considered a subgenus of Eptesicus, har

Audiovisual media and automatic speech recognition : A methodological reflection

The article maps the pitfalls and affordances of automatic speech recognition in the study of audiovisual media and digital history more broadly. Three key topics are emphasized: first, the collaboration between scholars and audiovisual archives and the potential of automatic speech recognition to transform the way scholars navigate and engage with audiovisual media history; second, what knowledge

Visualising microstructural dynamics of titanium aluminium nitride coatings under variable-temperature oxidation

Understanding the link between titanium-aluminium nitride's (Ti1-xAlxN) physicochemical properties and structural dynamics during operation is essential to designing and fabricating advanced ceramic coatings. Here, we directly visualise the oxidation of Ti1-xAlxN (for x = 0, 0.18, 0.44, & 0.67) coatings from 100 to 1000 °C using environmental transmission electron microscopy (ETEM) imaging and

Detailed anatomy at 7T

Selected high resolution axial images obtained from a 7T MRI scanner have been labeled to provide detailed information about the subtle structures found in the cerebellum and brainstem.

Prevalence of asystole during tilt test-induced vasovagal syncope may depend on test methodology

This review addresses tilt-testing methodology by searching the literature which reports timing of asystole and loss of consciousness (LOC). Despite the Italian protocol being the most widely adopted, its stipulations are not always followed to the letter of the European Society of Cardiology guidelines. The discrepancies permit reassessment of the incidence of asystole when tilt-down is early, im

Cardiovascular Morbidity and Mortality Related to Non-Alcoholic Fatty Liver Disease : a Systematic Review and Meta-Analysis

BACKGROUND AND AIMS: Whether non-alcoholic fatty liver disease (NAFLD) is a cardiovascular (CV) risk factor is debated. We performed a systematic review and meta-analysis to assess the CV morbidity and mortality related to NAFLD in the general population, and to determine whether CV risk is comparable between lean and non-lean NAFLD phenotypes.METHODS AND RESULTS: We searched multiple databases, i

Getting at the Experience of Confinement in Detention

A distinguishing feature of youth detention homes—and any other prisonlike institution—is the fact that inmates cannot just leave. They might escape, and there are ways to be transferred, enjoy an excursion, and get permission for home visits, but typically the young people in this case are supposed to remain within their given institution. I have been eager to not only depict this feature of fielA distinguishing feature of youth detention homes—and any other prisonlike institution—is the fact that inmates cannot just leave.
