Ergo, SMIRK is safe : a safety case for a machine learning component in a pedestrian automatic emergency brake system

Integration of machine learning (ML) components in critical applications introduces novel challenges for software certification and verification. New safety standards and technical guidelines are under development to support the safety of ML-based systems, e.g., ISO 21448 SOTIF for the automotive domain and the Assurance of Machine Learning for use in Autonomous Systems (AMLAS) framework. SOTIF an

Identifying blood biomarkers for type 2 diabetes subtyping : a report from the ORIGIN trial

Aims/hypothesis: Individuals with diabetes can be clustered into five subtypes using up to six routinely measured clinical variables. We hypothesised that circulating protein levels might be used to distinguish between these subtypes. We recently used five of these six variables to categorise 7017 participants from the Outcome Reduction with an Initial Glargine Intervention (ORIGIN) trial into the

Effect of alkalinity on the diffusion of solvent-fractionated lignin through cellulose membranes

Mass transport of liberated lignin fragments from pits and fiber walls into black liquor is considered a determining step in the delignification process. However, our current understanding of the diffusion of lignin through cellulose and the influential parameter on this process is very limited. A comprehensive and detailed study of lignin mass transport through cellulosic materials is, therefore,

Partially calibrated semi-generalized pose from hybrid point correspondences

We study the problem of estimating the semi-generalized pose of a partially calibrated camera, i.e., the pose of a perspective camera with unknown focal length w.r.t. a generalized camera, from a hybrid set of 2D-2D and 2D-3D point correspondences. We study all possible camera configurations within the generalized camera system. To derive practical solvers to previously unsolved challenging config

The 2020/2021 Tokyo Olympics : Does Japan get the gold medal or the wooden spoon?

The Tokyo 2020/2021 Olympics will go down in history as the 'Pandemic Games'. Postponed by a year due to Covid-19, they were eventually held despite broad public protest and amidst the Delta variant wave. Japan brought home a record haul of medals, yet Prime Minister Suga Yoshihide resigned in ignominy shortly after the Games ended. So, was Tokyo 2020/2021 a 'success' or a 'failure', and for whom?

Co-design Process of a Digital Return-to-Work Solution for People with Common Mental Disorders : Stakeholder Perception Study

Background: Service users and other stakeholders have had few opportunities to influence the design of their mental health and return-to-work services. Likewise, digital solutions often fail to align with stakeholders’ needs and preferences, negatively impacting their utility. mWorks is a co-design initiative to create a digital return-to-work solution for persons with common mental disorders that

The metabolic profile of waist to hip ratio–A multi-cohort study

Background The genetic background of general obesity and fat distribution is different, pointing to separate underlying physiology. Here, we searched for metabolites and lipoprotein particles associated with fat distribution, measured as waist/hip ratio adjusted for fat mass (WHRadjfatmass), and general adiposity measured as percentage fat mass. Method The sex-stratified association of 791 metabol

Impact of storage time prior to cryopreservation on mechanical properties of aortic homografts

Optimal time spans in homograft procurement are still debatable among tissue banks and needs to be further investigated. Cell viability decreases at longer preparation intervals, but the effect on collagen and elastic fibers has not been investigated to the same extent. These fibers are of importance to the homograft elasticity and strength. The objective of this study was to analyze the mechanica

Educational desires, intensive parenting and shifting notions of childhood and learning among Chinese Singaporeans

This paper seeks to expand our lens on educational desires, parenting and shifting notions of childhood and learning in East Asia and beyond. While not explicitly centered on migration, I suggest that the educational mobilities needs to be understood in relation to a growing tension between parents’ desire to achieve conventional success and the desire to nurture the child’s emotional well-being.

Historical and citizen-reported data show shifts in bumblebee phenology over the last century in Sweden

Bumblebees are a key taxon contributing to the provision of crop pollination and ecosystem functioning. However, land use and climate change are two of the main factors causing bee decline across the world. In this study, we investigated how the flight period of bumblebee spring queens has shifted over the last century in Sweden, and to what extent such shifts depended on climate change, landscape

Experiences of Using Weighted Blankets among Children with ADHD and Sleeping Difficulties

Introduction. Sleeping difficulties are common in children with attention deficit hyperactivity disorder (ADHD). A sleep intervention with weighted blankets was designed to increase current understanding of using weighted blankets to target children’s individual needs in connection with sleep and daytime functioning. Aim. To explore how children with ADHD and sleeping difficulties experience the u

Remarkable performance recovery in highly defective perovskite solar cells by photo-oxidation

Exposure to environmental factors is generally expected to cause degradation in perovskite films and solar cells. Herein, we show that films with certain defect profiles can display the opposite effect, healing upon exposure to oxygen under illumination. We tune the iodine content of methylammonium lead triiodide perovskite from understoichiometric to overstoichiometric and expose them to oxygen a

Numerical simulation of two-phase flow in gas diffusion layer and gas channel of proton exchange membrane fuel cells

Liquid water within the cathode Gas Diffusion Layer (GDL) and Gas Channel (GC) of Proton Exchange Membrane Fuel Cells (PEMFCs) is strongly coupled to gas transport properties, thereby affecting the electrochemical conversion rates. In this study, the GDL and GC regions are utilized as the simulation domain, which differs from previous studies that only focused on any one of them. A Volume of Fluid

Pulmonary Hypertension Phenotype Can Be Identified in Heart Failure With Reduced Ejection Fraction Using Echocardiographic Assessment of Pulmonary Artery Pressure With Supportive Use of Pressure Reflection Variables

Background: Pulmonary hypertension (PH) is frequent in patients with heart failure and reduced ejection fraction (HFrEF) with 2 different phenotypes: isolated postcapillary PH (IpcPH) and, with the worst prognosis, combined pre- and postcapillary PH (CpcPH). The aims of the present echocardiography study were to investigate (1) the ability to identify PH phenotype in patients with HFrEF using the

Är det något särskilt med äldres missbruksproblem?

Är det något särskilt med äldres missbruksproblem? Finns det en ålder då samhället bör ge upp ambitionen att ge behandling och i stället sträva efter att skapa ett värdigt liv? Är lågtröskelboenden där äldre får fortsätta missbruka en värdig och human lösning? Eller ett uttryck för ålderism där samhället ger upp ambitionen att förändra livet för äldre personer?

Perspektiv på utsatthet och problem under åldrandet

För många är åldrandet relativt problemfritt, även om sjukdomar och funktionsnedsättningar blir vanligare ju längre vi lever. Vid sidan av problemfriheten finns det olika typer av utsatthet, utmaningar och bekymmer som kan drabba äldre på ett särskilt sätt. Det kan handla om alltifrån missbruk och ensamhet till svårigheter att betala räkningar i ett samhälle som blir allt mer digitalt. Den här ant

Utifrån ålder eller behov? – Ålder som organiserande princip för stödinsatser till äldre

Moral economy studies have investigated public opinion as to who should get what and why, and concluded that older people constitute a group that is perceived to deserve and be in need of support from society. A weakness of the approach is that the category of older people is taken for granted and specific age-limits are left unproblematized. The present study investigates views among municipal ne
