In this paper we present a novel algorithm for onboard radial distortion correction for unmanned aerial vehicles (UAVs) equipped with an inertial measurement unit (IMU), that runs in real-time. This approach makes calibration procedures redundant, thus allowing for exchange of optics extemporaneously. By utilizing the IMU data, the cameras can be aligned with the gravity direction. This allows us
Myocardial perfusion scintigraphy, which is a non-invasive imaging technique, is one of the most common cardiological examinations performed today, and is used for diagnosis of coronary artery disease. Currently the analysis is performed visually by physicians, but this is both a very time consuming and a subjective approach. These are two of the motivations for why an automatic tool to support th
In this paper we consider a collection of relative pose problems which arise naturally in applications for visual indoor navigation using unmanned aerial vehicles (UAVs). We focus on cases where additional information from an onboard IMU is available and thus provides a partial extrinsic calibration through the gravitational vector. The solvers are designed for a partially calibrated camera, for a
For diagnosis and risk assessment in patients with stable ischemic heart disease, myocardial perfusion scintigraphy is one of the most common cardiological examinations performed today. There are however many motivations for why an artificial intelligence algorithm would provide useful input to this task. For example to reduce the subjectiveness and save time for the nuclear medicine physicians wo
BACKGROUND: Cerebrospinal fluid (CSF) biomarkers are associated with conversion from mild cognitive impairment to Alzheimer's disease (AD), but their predictive value for later end-points has been less evaluated with inconsistent results.OBJECTIVE: We investigated potential relationships between CSF amyloid-β1-42 (Aβ42), phosphorylated tau (P-tau), and total tau (T-tau) with time to nursing home p
BACKGROUND: With a growing elderly population worldwide, the prevalence of dementia is rapidly increasing. Studies from high income countries have shown that belonging to a minority ethnic group increases the risk of health disadvantages.OBJECTIVE: The aim of the present registry-based study was to identify potential differences in diagnostics, treatment, and care of individuals with dementia focu
Objectives: To analyse the living conditions and social outcomes (housing, engagement in employment or higher education, access to personal assistance and having a partner) in adults with cerebral palsy (CP) relative to their age, sex, communication ability, and motor skills. Methods: Cross-sectional registry-based study of 1,888 adults (1,030 males/858 females) with CP in the Swedish CP follow-up
Background: There is an increased risk of suicidality in gambling disorder (GD) and economic hardship is common in the population. Economic hardship itself is a risk factor for suicidality. This study aims to explore the risk of intentional self-harm in GD utilizing social welfare payment (SWP) as a proxy for economic hardship and exploring how economic hardship, gender, criminality, socioeconomic
OBJECTIVE: Primary hyperparathyroidism (pHPT) is characterized by excessive production of parathyroid hormone (PTH) due to parathyroid adenomas while uremic secondary HPT (sHPT) is caused by parathyroid hyperplasia in response to renal failure. Active vitamin D, 1,25-dihydroxyvitamin D(3) (1,25-(OH)(2)D(3)), with the vitamin D receptor (VDR) is involved in regulation of the calcium homeostasis tog
BACKGROUND: Sporadic primary hyperparathyroidism (pHPT) occurs separately and in several hereditary disorders including multiple endocrine neoplasia type 1. Irradiation to the neck, female gender, and age are well-identified risk factors that predispose to pHPT. The multiple endocrine neoplasia type 1 gene is the most commonly deranged gene in parathyroid adenomas and contains several polymorphism
OBJECTIVE: Glial cells missing (Gcm) was first identified as a binary switch between neuronal and glial determination in Drosophila. Two homologues of Drosophila Gcm have been identified in mice and humans, namely Gcm1 and Gcm2. Mouse Gcm2 is restricted to parathyroid tissues and Gcm2 was recently identified as a master regulatory gene of parathyroid gland development as Gcm2 knockout mice lack pa
BACKGROUND: Loss of heterozygosity (LOH) at chromosome 1p is a common abnormality in both parathyroid tumors and pheochromocytomas. The recently characterized tumor suppressor gene RIZ1, located at 1p36, has emerged as a putative candidate to be involved in endocrine tumorigenesis.MATERIAL: Presence of allelic loss, promoter hypermethylation, and mutational aberrations of the RIZ1 gene were invest
What roles are military institutions expected to play in today's rapidly changing security environment? How are they supposed to interact with the society they are tasked to protect? These questions have been posed by classical military sociologists as well as by a newer generation of scholars. Yet so far, a comprehensive mapping of the military's potential roles in contemporary society is missing
In this paper, we present a side-channel attack on a first-order masked implementation of IND-CCA secure Saber KEM. We show how to recover both the session key and the long-term secret key from 24 traces using a deep neural network created at the profiling stage. The proposed message recovery approach learns a higher-order model directly, without explicitly extracting random masks at each executio
Active vitamin D, 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)], plays a pivotal role in calcium homeostasis and bone metabolism. Circulating levels of 1,25(OH)(2)D(3) are thought to be dependent mainly on the activity of the renal cytochrome P450 enzyme 25-hydroxyvitamin D(3)-1alpha-hydroxylase (1alpha-hydroxylase), which is potently induced by PTH. However, 1alpha-hydroxylase activity or expressi
OBJECTIVE: Parathyroid adenomas frequently harbour deletions of genomic DNA at chromosome regions 1p, 6q and 11q. In this study we related clinical characteristics in 56 patients with primary hyperparathyroidism (pHPT) to loss of heterozygosity (LOH) in these chromosome regions.DESIGN: LOH analysis was performed on 56 sporadic parathyroid tumours using a total of 18 microsatellite markers for chro
Sepsis is associated with exaggerated neutrophil responses although mechanisms remain elusive. The aim of this study was to investigate the role of c-Abelson (c-Abl) kinase in neutrophil extracellular trap (NET) formation and inflammation in septic lung injury. Abdominal sepsis was induced by cecal ligation and puncture (CLP). NETs were detected by electron microscopy in the lung and by confocal m
Objective: A few studies have suggested that patients with inflammatory arthritis (IA) who remain persistent with subcutaneous TNF-α inhibitors (SC-TNFi) incur lower health care costs than patients who discontinue treatment, whereas data on the impact of non-persistence on indirect costs are largely lacking. Furthermore, existing estimates are based on fixed follow-ups, in relation to treatment in
