We present an online learning analysis of minimax adaptive control for the case where the uncertainty includes a finite set of linear dynamical systems. Precisely, for each system inside the uncertainty set, we define the model-based regret by comparing the state and input trajectories from the minimax adaptive controller against that of an optimal controller in hindsight that knows the true dynam

The substitution of scandium in fullerene single‐molecule magnets (SMMs) DySc2N@C80 and Dy2ScN@C80 by lutetium has been studied to explore the influence of the diamagnetic metal on the SMM performance of dysprosium nitride clusterfullerenes. The use of lutetium led to an improved SMM performance of DyLu2N@C80, which shows a higher blocking temperature of magnetization (TB=9.5 K), longer relaxation

Biological effects of electromagnetic fields (EMF) on the blood‐brain barrier (BBB) can be studied in sensitive and specific models. In a previous investigation of the permeability of the blood‐brain barrier after exposure to the various EMF‐components of proton magnetic resonance imaging (MRI), we found that the exposure to MRI induced leakage of Evans Blue labeled proteins normally not passing t

The biological effects of electromagnetic fields (EMFs) on the blood-brain barrier (BBB) can be studied in sensitive and specific models. In a previous investigation of the permeability of the BBB after exposure to the various EMF -components of proton magnetic resonance imaging (MRI), we found that exposure to MRI induced leakage of Evans-blue-labelled proteins which do not normally pass the BBB

The pine sawfly pheromone precursor 3,7-dimethyl-2-pentadecanol (diprionol) was quantified by gas chromatography in different body parts of virgin female Neodiprion sertifer. About one-third of the total amount (approx. 10 ng per female) was found in each of head + thorax, abdominal segments 1-3, and the remaining abdomen. Diprionol was also found in the respective parts of pupae, but in lower amo

A software application combining process and input–output analysis (EAP) was used toanalyze 218 consumer products and services for environmental impacts over their lifecycle. The results are available as carbon dioxide equivalents, land use and water use perkg and per SEK. The products and services were chosen either because they are consumedby many Swedish consumers today or because they may be c

Parkinson’s disease (PD) can produce postural abnormalities of the standing body position such as kyphosis. We investigated the effects of PD, deep brain stimulation (DBS) in the subthalamic nucleus (STN), vision and adaptation on body position in a well-defined group of patients with PD in quiet standing and during balance perturbations. Ten patients with PD and 25 young and 17 old control partic

Previous studies have shown that injector aging adversely affects the diesel engine spray formation and combustion. It has also been shown that the oxygenated fuel additive tripropylene glycol monomethyl ether (TPGME) can lower soot emissions. In this study, the effects of injector aging and TPGME on the late cycle oxidation of soot were investigated using laser diagnostic techniques in a light-du

PURPOSE: At ∼3 years of age ∼50% of the children born with cleft palate present with phonological/articulatory difficulties. Differences between children with and without cleft palate have been reported to decline with age; however, the phonology in children with cleft palate at pre-school age/early school age has rarely been explored. The purpose of this study was to assess phonology in children

Depression is a common, recurrent disorder. There is a need for readily available treatments with few negative side effects, that demands little resources and that are effective both in the short- and long term. Our aim was to investigate the long-term effectiveness of two different interventions; physical exercise and internet-based cognitive behavioural therapy (internet-CBT), compared to usual

This paper describes and discusses the development of mobile exergames for children with cerebral palsy. The design process was built on co-design, and resulted in three activity games, two augmented reality (AR) games and one GPS based game. The resulting activity games were evaluated by 8 per-sons with cerebral palsy (CP). To complement this evaluation, the games have been evaluated against exis

Background: The response to neoadjuvant cisplatin-based chemotherapy (NAC) in muscle-invasive bladder cancer (MIBC) is impaired in up to 50% of patients due to chemoresistance, with no predictive biomarkers in clinical use. The proto-oncogene RNA-binding motif protein 3 (RBM3) has emerged as a putative modulator of chemotherapy response in several solid tumours but has a hitherto unrecognized role

The current study was aimed at highlighting the role of blood pancreatic amylase in the regulation of glucose homeostasis and insulin secretion in a porcine model of streptozotocin- (STZ-) induced diabetes and in a rat pancreatic beta-cell line, BRIN-BD11. Blood glucose, plasma insulin, and glucagon levels were measured following a duodenal glucose tolerance test (IDGTT), in four pigs with STZ-ind

Background: Anxiety and obstructive sleep apnea (OSA) coexist among adults with coronary artery disease (CAD) following revascularization. Continuous positive airway pressure (CPAP) is the first line treatment of OSA patients with daytime sleepiness. The current study evaluated the effect of CPAP on anxiety in CAD patients with nonsleepy OSA. Methods: Two hundred forty-four revascularized CAD pati

Purpose: A systematic review was conducted to analyze the inter-rater reliability, cross-informant consistency, test-retest reliability, and temporal stability of the Strengths and Difficulties Questionnaire (SDQ), and its ability to discriminate. Method: We searched three databases for articles about the SDQ (parent, teacher, and self-report version), used samples of children up to age 18 and rep

The effect of Cu on three different microbial endpoints was studied using different Cu sources, in order to check the usefulness of pure Cu salts to estimate the toxicity of commercial Cu fungicides on soil microbes. Cu additions caused similar dose-response curves of substrate induced respiration (SIR) decreases regardless of Cu source, i.e. the use of pure Cu salts to estimate the effect of Cu f

Two-dimensional Ruddlesden–Popper perovskites (2D RPPs) have been considered as promising building blocks for optoelectronic applications owing to optical properties comparable to the ones of 3D perovskites, together with superior stability. In addition, the more flexible structure adopted by such perovskites leads to a relaxation of the Goldschmidt tolerance factor (τ) requirement. Herein, we com
