The nonvolatile cryogenic memories can play an important role in realizing energy-efficient and scalable low-temperature electronics for quantum computing and future high-performance computing systems. In this article, we evaluate he cryogenic performance of HfOx-based resistive random access memory (RRAM) and demonstrate that the addition of extremely thin ∼0.5-nm AlOx barrier layers enables a h
Metal-halide perovskites (MHPs) have gained substantial interest in the energy and optoelectronics field. MHPs in nanostructure forms, such as nanocrystals and nanowires (NWs), have further expanded the horizons for perovskite nanodevices in geometry and properties. A partial anion exchange within the nanostructure, creating axial heterojunctions, has significantly augmented the potential applicat
A novel approach is introduced to modulate the threshold voltage of organic electrochemical transistors (OECTs) that are fabricated by electropolymerizing the channel material between the source and drain electrodes. To achieve this, we adjust the ratio of two water-soluble tri-thiophene monomers, which share the same backbone, but present either anionic or zwitterionic sidechains, during channel
Infectious and parasitic agents (IPAs) and their associated diseases are major environmental stressors that jeopardize bee health, both alone and in interaction with other stressors. Their impact on pollinator communities can be assessed by studying multiple sentinel bee species. Here, we analysed the field exposure of three sentinel managed bee species (Apis mellifera, Bombus terrestris and Osmia
Adult neurogenesis continues throughout life but declines dramatically with age and in neurodegenerative disorders such as Alzheimer's disease. In parallel, microglia become activated resulting in chronic inflammation in the aged brain. A unique type of microglia, suggested to support neurogenesis, exists in the subventricular zone (SVZ), but little is known how they are affected by aging. We anal
Variants in GBA1 are important genetic risk factors in Parkinson's disease (PD). GBA1 T369M has been linked to an ∼80 % increased PD risk but the reports are conflicting and the relevance of GBA1 variants in different populations varies. A lack of association between T369M and PD in the Swedish population was recently reported but needs further validation. We therefore investigated T369M in 1,808
European semi-natural grasslands are hotspots for biodiversity and important for the provisioning of multiple ecosystem services, but their extent has declined considerably during the past century. Increasing demands for agricultural and forest biomass risk causing further loss of grasslands, raising concern about a goal conflict between climate mitigation and biodiversity conservation. This study
Tunnel field-effect transistors (TFETs) are a potential alternative to MOSFETs for low-temperature electronics. We provide an in-depth experimental characterization of TFETs analyzing the fundamental physical behavior at different temperature regimes. TFET characteristics from 13 to 300 K both in forward and reverse bias are discussed by employing a variation in InAs/InGaAsSb/GaSb heterojunction v
Platinum-tin catalysts have been used industrially for decades, but their structural evolution under reaction conditions and the causes of their improved activity relative to platinum are still not well understood. In this study, we investigate Sn/Pt(111) and Sn/Pt(223) surface alloys during oxygen exposure and catalytic CO oxidation using grazing incidence X-ray absorption spectroscopy (GI-XAS).
Reactive oxygen species (ROS) are considered to be an indicator of particle-induced toxicity. We used a novel instrument, called Particle Into Nitroxide Quencher (PINQ), for real-time quantification of ROS for assessment of indoor particle sources. Of the sources tested, cigarette smoke was found to contain the highest ROS concentration, several times higher than incense smoke and secondary organi
Amyloids are elongated supramolecular protein self-assemblies. Their formation is a non-covalent assembly process and as such is fully reversible. Amyloid formation is associated with several neurodegenerative diseases, and the reversibility is key to maintaining the healthy state. Reversibility is also key to the performance of fibril-based biomaterials and functional amyloids. The reversibility
With the world facing severe ecological degradation, we hear calls for radical change more and more often. One of these calls is for degrowth in materially wealthy nations, including the Nordics. Degrowth fundamentally challenges the modern assumption that economic growth is good for humanity and the planet, and therefore necessitates change in civil society, state and production. In the contempor
Background: The Parkinson Disease (PD) Home Diary (HD) is a commonly used clinical outcome measure, but it has not been extensively compared to direct assessments by experienced observers.Objective: Validation of patient-reported HD by investigating the agreement between motor state assessments by patients and observers.Methods: This observational study included patients with PD and motor fluctuat
There is a growing interest in industry and academia in machine learning (ML) testing. We believe that industry and academia need to learn together to produce rigorous and relevant knowledge. In this study, we initiate a collaboration between stakeholders from one case company, one research institute, and one university. To establish a common view of the problem domain, we applied an interactive r
After World War I, millions of men went back from the war front promised of land, work and social justice, but their expectations were unfulfilled by the governments of European countries. In this context, the political landscape was enriched of new ideas, and several new parties, movements and associations born across Europe. In Italy, ANMIG (Disabled Ex-Servicemen National Association) was
Follow-up survey on legal status of information society service providers in the post-CDSM Directive era in Sweden, focusing on service providers as intermediaries and as users of copyright-protected content (March 2022). Phase 2 report, part of ReCreating Europe project WP6 - Intermediaries.
Background: Metabolite profiles provide snapshots of the overall effect of numerous exposures accumulated over life courses, which may lead to health outcomes in the future. Objective: We hypothesized that the risk of all-cause mortality is linked to alterations in metabolism earlier in life, which are reflected in plasma metabolite profiles. We aimed to identify plasma metabolites associated with
Background: Accelerated reproductive aging, in women indicated by early natural menopause, is associated with increased coronary heart disease (CHD) risk in observational studies. Conversely, an adverse CHD risk profile has been suggested to accelerate menopause. Objectives: To study the direction and evidence for causality of the relationship between reproductive aging and (non-)fatal CHD and CHD
A major challenge of genome-wide association studies (GWASs) is to translate phenotypic associations into biological insights. Here, we integrate a large GWAS on blood lipids involving 1.6 million individuals from five ancestries with a wide array of functional genomic datasets to discover regulatory mechanisms underlying lipid associations. We first prioritize lipid-associated genes with expressi
There is a need of problematizing taken for granted assumptions in the conceptualization of collaborative housing when attempting to link collaborative housing and social integration. What are the difficulties and opportunities that migrants and non-migrants face in accessing collaborative housing projects? Addressing such type of questions will help to capture exclusionary processes affecting old
