Purpose: To evaluate the validity and the reliability of the Oura Ring Generation 3 (Gen3) with Oura Sleep Staging Algorithm 2.0 (OSSA 2.0) through multi-night polysomnography (PSG). Participants and methods: Participants were 96 generally healthy Japanese men and women aged between 20 and 70 years contributing with 421,045 30-s epochs. Sleep scoring was performed according to American Academy of

Developing efficient and robust computational models is essential to improve our understanding of protein solution behavior. This becomes particularly important to tackle the high-concentration regime. In this context, the main challenge is to put forward coarse-grained descriptions able to reduce the level of detail, while retaining key features and relevant information. In this work, we develop

Recombinant human bone morphogenetic protein-2 (rhBMP-2) has been FDA-approved for lumbar fusion, but supraphysiologic initial burst release due to suboptimal carrier and late excess bone resorption caused by osteoclast activation have limited its clinical usage. One strategy to mitigate the pro-osteoclast side effect of rhBMP-2 is to give systemic bisphosphonates, but it presents challenges with

How should democratic states approach and respond to secessionist movements using tactics contrary to the constitution to achieve their goals? What is the role of international human rights mechanisms in these processes? This article sheds light on these questions by examining how the UN Human Rights Committee approached and assessed two complaints that came before it in the wake of the Catalan De

A new growth approach, based on the hot-wall metalorganic chemical vapor deposition concept, is developed for high-quality homoepitaxial growth of Si-doped single-crystalline β -Ga 2 O 3 layers on (010)-oriented native substrates. Substrate annealing in argon atmosphere for 1 min at temperatures below 600 ° C is proposed for the formation of epi-ready surfaces as a cost-effective alternative to th

Flexibility can support the energy transition and improve the efficiency of heat supply to buildings. This study tests price models for the inclusion of heat pumps (HPs) in district heating network (DHN). Various price models were tested in two cases in Sweden. In Sweden, DH companies are increasingly confronted with instances where building owners invest in a HP and only use DH when it is too col

In the context of higher demands on the development of clean energy technologies due to the issue of water shortage in China and the implementation of the 2060 carbon-neutral objective, floating photovoltaic (FPV) systems present novel opportunities for transforming the energy structure through land conservation and enhancement of power generation efficiency compared to conventional solar systems.

The response of clouds to the changes in climate is uncertain, and the representation of the cloud-climate feedback is a key challenge in the global circulation models (GCM) for future climate projections. Factors contributing to this uncertainty include processes that involve particles of various sizes and phases, as well as the interactions between these particles and the surrounding atmosphere.

Public libraries serve as social infrastructures that foster interpersonal connections and promote well-being and cohesion. In order to explore the role played by libraries in the process of social infrastructuring, we conducted a zine-making workshop with librarians. This workshop facilitated collegial conversations and provided an opportunity for participants to familiarize themselves with the cPublic libraries serve as social infrastructures that foster interpersonal connections and promote well-being and cohesion.

Bivariate extreme value distributions can be used to model dependence of observations from random variables in extreme levels. There is no finite dimensional parametric family for these distributions, but they can be characterized by a certain one-dimensional function which is known as Pickands dependence function. In many applications the general approach is to estimate the dependence function wi

Denna rapport sammanställer och sammanfattar arbetsmaterial i förhållande tillarbetsgruppens fyra frågeställningar och syftar till att ge underlag för verksamheternas fortsatta diskussioner. På så sätt följer den inte gängse utformning för en FoU-rapport och gör inte heller anspråk på att rapportera några färdiga slutsatser. Analyserna kommer att bearbetas vidare på olika sätt; praktiskt i verksam

For many children, their home is where they first encounter digital media technologies. The aim of this study is to investigate how children 0 – 3 years old engage in digital media. We address digital literacies as a sociocultural mindset and a toolbox with attention to skills and comprehensions as well as how children express their agency. The overall research question is: What skills, comprehens

This paper examines the profound impact of digital technology on Classical and Mediterranean archaeology, with a focus on digital field recording and infrastructure. Using the 'skeuomorphism of practice' framework, it traces the integration of technology into our current practice. The Swedish Pompeii project is used as a case study to illustrate the adoption of 3D models into traditional archaeolo

How to construct and facilitate participatory and playful opera? Through this interdisciplinary artistic research project within the fields of music drama / opera and game studies, I seek to develop a framework for alternative and innovative opera concepts – based on immersion, relations and play. The term that I propose for this type of contemporary music theatre is ludo-immersive opera (related

The measurement and application of residual dipolar couplings (RDCs) in solution NMR studies of biological macromolecules has become well established over the past quarter of a century. Numerous methods for generating the requisite anisotropic orientational molecular distribution have been demonstrated, each with its specific strengths and weaknesses. In parallel, an enormous number of pulse schem

Resonance assignment and structural studies of larger proteins by nuclear magnetic resonance (NMR) can be challenging when exchange broadening, multiple stable conformations, and 1H back-exchange of the fully deuterated chain pose problems. These difficulties arise for the SARS-CoV-2 Main Protease, a homodimer of 2 × 306 residues. We demonstrate that the combination of four-dimensional (4D) TROSY-

The 68-kDa homodimeric 3C-like protease of SARS-CoV-2, Mpro (3CLpro/Nsp5), is a promising antiviral drug target. We evaluate the concordance of models generated by the newly introduced AlphaFold2 structure prediction program with residual dipolar couplings (RDCs) measured in solution for 15N-1HN and 13C′-1HN atom pairs. The latter were measured using a new, highly precise TROSY-AntiTROSY Encoded R

Understanding the factors that underpin the enormous catalytic proficiencies of enzymes is fundamental to catalysis and enzyme design. Enzymes are, in part, able to achieve high catalytic proficiencies by utilizing the binding energy derived from nonreacting portions of the substrate. In particular, enzymes with substrates containing a nonreacting phosphodianion group coordinated in a distal site
