Tuning composition in graded AlGaN channel HEMTs toward improved linearity for low-noise radio-frequency amplifiers

Compositionally graded channel AlGaN/GaN high electron mobility transistors (HEMTs) offer a promising route to improve device linearity, which is necessary for low-noise radio-frequency amplifiers. In this work, we demonstrate different grading profiles of a 10-nm-thick AlxGa1-xN channel from x = 0 to x = 0.1 using hot-wall metal-organic chemical vapor deposition (MOCVD). The growth process is dev

Social dimensions of Resilience and Climate Change: A rapid review of theoretical approaches

The social dimensions of resilience and their relationship with social capital have received little attention in climate change research. This article aims to provide an understanding of the structural, cognitive, and human rights-based interconnection of social capital and the social dimension of resilience. This article provides a rapid review of published studies on the social dimensions of res

Association of Gout Polygenic Risk Score With Age at Disease Onset and Tophaceous Disease in European and Polynesian Men With Gout

Objective: To determine whether a gout polygenic risk score (PRS) is associated with age at gout onset and tophaceous disease in European, East Polynesian, and West Polynesian men and women with gout. Methods: A 19-variant gout PRS was produced in 7 European gout cohorts (N = 4,016), 2 East Polynesian gout cohorts (N = 682), and 1 West Polynesian gout cohort (N = 490). Sex-stratified regression mo

Certification of non-classicality in all links of a photonic star network without assuming quantum mechanics

Networks composed of independent sources of entangled particles that connect distant users are a rapidly developing quantum technology and an increasingly promising test-bed for fundamental physics. Here we address the certification of their post-classical properties through demonstrations of full network nonlocality. Full network nonlocality goes beyond standard nonlocality in networks by falsify

Co-administration with A1M does not influence apoptotic response of 177Lu-octreotate in GOT1 neuroendocrine tumors

Recombinant α1-microglobulin (A1M) is a proposed radioprotector during 177Lu-octreotate therapy of neuroendocrine tumors (NETs). To ensure a maintained therapeutic effect, we previously demonstrated that A1M does not affect the 177Lu-octreotate induced decrease in GOT1 tumor volume. However, the underlying biological events of these findings are still unknown. The aim of this work was to examine t

Ag-oxide signature in Ag 3d photoelectron spectra : A study on free nanoparticles

Over decades the Ag 3d-level binding energy has been puzzling researchers with its unusual sign and value in silver oxides. For the absolute majority of metals, the metal-to-oxide binding energy shifts are positive and depend significantly on the oxidation state, while in Ag-oxides the oxide shift was time after time reported negative, small, and close for the two very different Ag(I) and Ag(III)

The photoreceptor protective cGMP-analog Rp-8-Br-PET-cGMPS interacts with cGMP-interactors PKGI, PDE1, PDE6, and PKAI in the degenerating mouse retina

The inherited eye disease retinitis pigmentosa (RP) causes the loss of photoreceptors by a still unknown cell death mechanism. During this degeneration, cyclic guanosine-3′,5′-monophosphate (cGMP) levels become elevated, leading to over-activation of the cGMP-binding protein cGMP-dependent protein kinase (PKG). cGMP analogs selectively modified to have inhibitory actions on PKG have aided in imped

Comparing minimum number of individuals and abundance from non-invasive DNA sampling and camera trapping in the red fox (Vulpes vulpes)

Applying the most appropriate sampling method is essential for estimating population size. Sampling methods and techniques to estimate abundance may be limited by environmental characteristics, species traits, specific requirements of the techniques, or the economic resources to carry out the sampling. Thus, evaluating multiple sampling methods in monitoring populations is essential for establishi

Scale fragilities in localized consensus dynamics

We consider distributed consensus in networks where the agents have integrator dynamics of order two or higher (n≥2). We assume all feedback to be localized in the sense that each agent has a bounded number of neighbors and consider a scaling of the network through the addition of agents in a modular manner, i.e., without re-tuning controller gains upon addition. We show that standard consensus al

Research and education in analytical chemistry — industrial and academic perspectives from a survey conducted in Sweden

Analytical chemistry is a sub-discipline of chemistry that even young schoolchildren encounter at an early stage in their education. Gravimetry and measurement uncertainties are aspects that form a part of such education, as well as measurements of pH and colorimetry. These are all an integral part of children’s early educational experiences, which shows the importance of this discipline within th

Experiences of People with Cardiovascular Disease during COVID-19 in Sweden : A Qualitative Study

Although people with cardiovascular conditions were subjected to more rigorous restrictions during the COVID-19 pandemic, there is limited knowledge of how the restrictions affected their lives and well-being. Thus, the aim of this study was to describe how people with cardiovascular conditions experienced their life situation and physical and mental health during the second wave of the pandemic i

Is the Universe Infinite? Characterising a Hierarchy of Reasoning in Student Conceptions of Cosmology Concepts Using Open-Ended Surveys

Cosmology presents students with ideas that stimulate their curiosity and brings together various concepts from STEM that call on a variety of reasoning types across multiple representational modes, involving subtleties of spacetime relations, a variety of models and evidence requiring multiple lines of high precision observations. This study investigated high school students’ levels and types of

Postmortem lung and heart examination of COVID-19 patients in a case series from Jordan

Background: Coronavirus disease 2019 (COVID-19) has emerged as a pandemic for more than 2 years. Autopsy examination is an invaluable tool to understand the pathogenesis of emerging infections and their consequent mortalities. The aim of the current study was to present the lung and heart pathological findings of COVID-19-positive autopsies performed in Jordan. Methods: The study involved medicole

Do Nitrogen and Phosphorus Additions Affect Nitrogen Fixation Associated with Tropical Mosses?

Tropical cloud forests are characterized by abundant and biodiverse mosses which grow epiphytically as well as on the ground. Nitrogen (N)-fixing cyanobacteria live in association with most mosses, and contribute greatly to the N pool via biological nitrogen fixation (BNF). However, the availability of nutrients, especially N and phosphorus (P), can influence BNF rates drastically. To evaluate the

Homeownership While Aging-How Health and Economic Factors Incentivize or Disincentivize Relocation : Protocol for a Mixed Methods Project

BACKGROUND: Many factors influence housing choices among older adults, but far from all have been identified. There is little systematic analysis that has included economic factors and virtually no knowledge about the interplay among perceived costs of moving, health status, and the mobility rate of older homeowners. It is currently unclear whether economic factors influence older adults' willingn

Early Neolithic flint extraction in south-western Sweden : Transregional practices on a local scale

Recent studies relate the introduction of Early Neolithic flint mining practices to the migration and rapid expansion of agricultural groups from north-western continental Europe into present-day Britain and southern Scandinavia. Here, the authors critically analyse this hypothesis, using a case study from south-western Sweden to demonstrate how transregional processes played out locally with thei

The importance of context-a qualitative study exploring healthcare practitioners' experiences of working with patients at home after a stroke

BACKGROUND: Stroke significantly impacts individuals, leading to the need for long-lasting rehabilitation and adaptation to environmental demands. Rehabilitation after stroke is increasingly performed in patients' homes, and it is argued that rehabilitation in this context is more person-centred and positively impacts client outcomes. However, the role of environmental factors in this process is l
