Popular Abstract in Swedish Multikonjugerad Adaptiv Optik för Astronomiska Teleskop 1. Atmosfärisk turbulens Allt sedan man på 1600-talet började bruka optiska instrument inom astronomin, för att understödja det mänskliga ögat då man beskådade stjärnhimlen, har astronomer strävat efter att bygga allt större och bättre teleskop för att kunna se längre ut i rymden och skönja allt ljussvagare objekt.This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future. The first part is an introductory exposition on atmospheric turbulence, adaptive optics (AO) and MCAO, esta

Popular Abstract in Swedish Människor (och andra arter) har en grundläggande förmåga att anpassa sig till och lära sig hur omgivningen är strukturerad. Ofta lär vi oss struktur indirekt, utan att direkt och avsiktligt studera strukturen ifråga. Klassiska vardagsexempel på tämligen oavsiktlig strukturinlärning är språkinlärning, utveckling av musikaliska preferenser, inlärning av sociala regler, ocPeople can become sensitive to the general structure of different parts of the environment, often without studying that general structure directly, but through being incidentally exposed to instances that conform to the structure. When such learning proceeds unintentionally and gives rise to knowledge that is difficult to verbalize it is often referred to as implicit learning. One of the most comm

The effort to electrify society has in recent years resulted in major changes in the transportation sector. Charging time remains a challenge in several applications such as transportation and heavy machinery. A proposed solution that shortens the energy replenishment time and adds flexibility in loading the grid is to battery-swapping: exchanging the depleted battery for a fully charged one. In s

We investigated the role of cultural experience in the search advantage for happy faces. European British participants living in the UK, Asian Japanese participants living in Japan, and Asian Japanese participants living in the UK, were required to search for a happy or an angry face target against a background of neutral facial expressions, using Asian Japanese and European American faces.

BACKGROUND: The majority of out-of-hospital cardiac arrests (OHCAs) occur at place residence, which is associated with worse outcomes in unselected prehospital populations. Our aim was to investigate whether location of arrest was associated with outcome in a selected group of initial survivors admitted to intensive care.METHODS: This is a post-hoc analysis of the Targeted Temperature Management a

Background: Ambulatory oxygen therapy is prescribed for patients with chronic lung diseases who experience exertional hypoxemia. However, available devices may not adequately meet user requirements, and their performance characteristics are heterogeneous. Objective: This study aims to identify devices available for delivery of ambulatory oxygen therapy, the technologies that they use to generate o

Aim: We explored preferences for prognostic test performance characteristics and error tolerance in decisions regarding withdrawal or continuation of life-sustaining therapy (LST) after cardiac arrest in a diverse cohort of medical providers. Methodology: We distributed a survey through professional societies and research networks. We asked demographic characteristics, preferences for prognostic t

The landscape of healthcare is experiencing a digitalization shift, transferring many medical activities to the patients’ homes, a phenomenon commonly referred to as Hospital-at-Home. While Internet of Things (IoT) devices facilitate the building of such systems, there is a need for powerful middleware that encapsulates device-to-device communication, and enables the construction of user-friendly,

Calibration of network nodes using only time differences of arrival (TDOA) measurements opens up for interesting applications in wireless ad-hoc sensor networks, e.g. finding the positions of cell phones by only ambient sounds or radio. We present two novel approaches for the problem of self-calibration of network nodes using only TDOA when both receivers and transmitters are unsynchronized. We co

Plastic’s unique properties are vital for a sustainable future, but its excessive global use signifies consumer society’s wastefulness, often found in short-lived products. Plastic development has overlooked recycling needs, resulting in low material recycling due to a wide array of plastic types with varying additives, leading to recycling challenges. Research focused on thermoplastics aims to re

When discussing the relationship between religion and LGBTQIA+ rights in Europe today, the two are often framed by both religious and secular representatives as oppositional forces. While the rights of sexual and gender minorities are frequently described as symbols of progress and modernity within liberal democracies, religious communities and traditions are commonly portrayed as defenders of tra

Bakgrund: Patienter med avancerad gastrointestinal (GI) cancer har en hög symtombörda, vilket ofta medför behov av akutsjukvård. Integration av tidig, hem-baserad specialiserad palliativ vård (SPV) tillsammans med tumörspecifik behandling kan påverka behov av akut sjukvård.Metoder: Vid initiering av palliativ kemoterapi randomiserades patienter med avancerad GI-cancer till tidig hem-baserad SPV inBackgroundPatients with advanced gastrointestinal (GI) cancer experience a high symptom burden which frequently necessitates emergency care. Integration of early home-based specialised palliative care (SPC) with tumour-specific treatments may impact emergency healthcare use.MethodsAt the initiation of palliative chemotherapy, patients with advanced GI cancer were randomised to early home-based SPC

The mechanism of atomic and molecular ionization in intense, ultra-short laser fields is a subject which continues to receive considerable attention. An inherent difficulty with techniques involving the tight focus of a laser beam is the continuous distribution of intensities contained within the focus, which can vary over several orders of magnitude. The present study adopts time of flight mass s

To describe outdoor barriers in the nearby home environments of very old people, and to investigate whether the presence of these environmental barriers differed between users and non-users of mobility devices (MDs). Method: Baseline data on 397 Swedish people aged 80-89 years, collected with a study-specific question on MD use and a subset of the environmental component of the Housing Enabler ins

Introduction: The pulsatility indices of the umbilical and uterine arteries are used as the surrogate measures of utero-placental perfusion. Combining the two might simplify the evaluation of total placental vascular impedance, possibly improve prediction of adverse outcomes, and help identify pregnancies with suspected fetal growth restriction that need more intense surveillance.
