Minimax Linear Optimal Control of Positive Systems

We present a novel class of minimax optimal control problems with positive dynamics, linear objective function and homogeneous constraints. The proposed problem class can be analyzed with dynamic programming and an explicit solution to the Bellman equation can be obtained, revealing that the optimal control policy (among all possible policies) is linear. This policy can in turn be computed through

Utlandsfödda kvinnors upplevelser av preventivmedelsrådgivning. - behovet av att känna sig inkluderad, en kvalitativ studie.

Bakgrund: Barnmorskor i Sverige får i enlighet med Socialstyrelsens självständigt förskriva och ge preventivmedelsrådgivning och förskriva preventivmedel. Vid preventivmedelsrådgivning kan det finnas utmaningar kopplat till rådgivningssituationen och barnmorskan bär ett ansvar att främja sexuella och reproduktiv hälsa. Det finns få studier i en svensk kontext som fokuserar på utländska kvinnors up

Unfinished Business

How can microsocial rituals connected to a specific site be used as interaction templates for artistic purposes? And how can we distort such rituals artistically in order to make them memorable events? As artists, we regard distortion as the process that gives character and distinction to things and situations, as well as something that confuses and enriches information and interpretation. Through

Switchable Broadband Terahertz Absorbers Based on Conducting Polymer-Cellulose Aerogels

Terahertz (THz) technologies provide opportunities ranging from calibration targets for satellites and telescopes to communication devices and biomedical imaging systems. A main component will be broadband THz absorbers with switchability. However, optically switchable materials in THz are scarce and their modulation is mostly available at narrow bandwidths. Realizing materials with large and broa

Head-to-head comparison of two loop-mediated isothermal amplification (LAMP) kits for diagnosis of malaria in a non-endemic setting

Background: Light microscopy and rapid diagnostic tests (RDT) have long been the recommended diagnostic methods for malaria. However, in recent years, loop-mediated isothermal amplification (LAMP) techniques have been shown to offer superior performance, in particular concerning low-grade parasitaemia, by delivering higher sensitivity and specificity with low laboratory capacity requirements in li

Selection despite low genetic diversity and high gene flow in a rapid island invasion of the bumblebee, Bombus terrestris

Invasive species are predicted to adjust their morphological, physiological and life-history traits to adapt to their non-native environments. Although a loss of genetic variation during invasion may restrict local adaptation, introduced species often thrive in novel environments. Despite being founded by just a few individuals, Bombus terrestris (Hymenoptera: Apidae) has in less than 30 years suc

The Artificial Lyricist : Prototyping an Interactive Opera for Humans and Machines

To probe into the artistic possibilities of Artificial Intelligence (AI) generating operatic elements, we have engaged in a practice-led inquiry as designers and artists. We took the process of prototyping a chamber opera with interactive features as our starting point, exploring how AI could work as a source of stimuli in opera productions, and how prototyping might add to the design and evaluati

Magmatism during late Ordovician-early Silurian accretion of the Caledonides of Arctic Scandinavia : the Halti-Guolasjavri area revisited

In the Scandinavian Caledonides, evidence of syn-collisional magmatism related to extensional basin development immediately prior to late Silurian Baltica-Laurentia collision was considered restricted to exotic terranes until late Silurian ages were obtained from the Halti Igneous Complex (HIC), hosted by a thrust sheet (Corrovarre Nappe, CN) of continental affinity. Various orogenic models for th

Shocked quartz in sandstone from the buried Ilkurlka impact structure, Officer Basin, Western Australia

The Ilkurlka structure is an ~12 km diameter buried circular aeromagnetic anomaly within the Officer Basin in Western Australia. Prior studies postulated a range of origins, including meteorite impact. We report the presence of pervasive deformation in the first drill cores from the structure. Brecciated sandstone and siltstone contain arrays of quartz grains with concussion fractures and rare sho

Childish Shelf - New purpose, no new purchase

This project is aiming towards designing to extend the lifespan of children’s belongings to reduce excessive owning and over consumption amongst parents. Today, there is an issue of parents of small children needing to own many of the same products that they often need to replace and exchange as the child grows older. It affects both the environment and the personal economy of the parents. The re

Camouflage efficiency in a colour-polymorphic predator is dependent on environmental variation and snow presence in the wild

Colour polymorphism can be maintained by colour morph-specific benefits across environmental conditions. Currently, the amount and the duration of snow cover during winter decrease especially in northern latitudes, which can alter the potential for camouflage of animals with light and dark morphs. Tawny owls, Strix aluco, are colour-polymorphic avian predators with dark (brown) and light (grey) co

A Paradigm Shift in the Management of Patients with Parkinson's Disease

Background: Technological evolution leads to the constant enhancement of monitoring systems and recording symptoms of diverse disorders. Summary: For Parkinson's disease, wearable devices empowered with machine learning analysis are the main modules for objective measurements. Software and hardware improvements have led to the development of reliable systems that can detect symptoms accurately and

Testing the Applicability of Quartz and Feldspar for Luminescence Dating of Pleistocene Alluvial Sediments in the Tatra Mountain Foothills, Slovakia

Luminescence dating is a widely used method in combination with sedimentological analysis for reconstructing the landscape development of the Quaternary period. In this study, quartz and K-feldspar measurements were used to evaluate the luminescence characteristics with the aim of dating the deposits. The sediments were sampled from an abandoned gravel pit in the Biely Váh valley and eight sites i

Evaluating the 11-year solar cycle and short-Term 10Be deposition events with novel excess water samples from the East Greenland Ice-core Project (EGRIP)

10Be is produced by the interaction between galactic cosmic rays (GCRs) and solar energetic particles (SEPs) with the Earth's atmospheric constituents. The flux of GCRs is modulated by the varying strength of the magnetic fields of the Earth and the Sun. Measurement of 10Be concentrations from polar ice cores is thus a valuable tool to reconstruct the variations in the geomagnetic field and solar

An Integrated Optimal Design Procedure for Pulse Transformer-Based Klystron Modulators for Long-Pulse High-Power Applications

Solid-state klystron modulators are typically based on oil-immersed high-voltage (HV) pulse transformers due to their high performance, robustness, and topological simplicity. However, in considering high-power multi-millisecond pulsed applications based on this topology, modulator power components and their design become increasingly complicated and, correspondingly, modulator size becomes proble

Fostering an innovation ecosystem for a public digital health platform

This short paper explores building innovation platforms in the public sector, particularly in public healthcare, through an ecological lens. While existing research has mainly focused on the platform owner's role in orchestrating innovation, this study investigates the strategies used by public organizations and widens the net to analyse how a digital health platform’s complementing actors contrib

Harnessing cognitive trajectory clusterings to examine subclinical decline risk factors

Cognitive decline in Alzheimer's disease and other dementias typically begins long before clinical impairment. Identifying people experiencing subclinical decline may facilitate earlier intervention. This study developed cognitive trajectory clusters using longitudinally based random slope and change point parameter estimates from a Preclinical Alzheimer's disease Cognitive Composite and examined

Airway contraction and cytokine release in isolated rat lungs induced by wear particles from the road and tire interface and road vehicle brakes

The dominant road traffic particle sources are wear particles from the road and tire interface, and from vehicle brake pads. The aim of this work was to investigate the effect of road and brake wear particles on pulmonary function and biomarkers in isolated perfused rat lungs. Particles were sampled from the studded tire wear of three road pavements containing different rock materials in a road si

The relationship between familial-genetic risk and pharmacological treatment in a Swedish national sample of patients with major depression, bipolar disorder, and schizophrenia

Using Swedish registers, we examine whether the prescription of and the response to antidepressants (AD), mood stabilizers (MS), and antipsychotics (AP) in the treatment of, respectively, major depression (MD), bipolar disorder (BD), and schizophrenia (SZ), are influenced by familial-genetic risk. We examined individuals born in Sweden 1960–1995 with a first diagnosis of MD (n = 257,177), BD (n =
