Volcanical and surficial process constraints on the formation of a lake basin in Jan Mayen, Norway

The volcanic island of Jan Mayen, located in the Norwegian – Greenland Sea, has very few lake basins out of which only one, Lake Nordlaguna, holds a permanent lake throughout the year. The island is volcanic and has been glaciated, but the lake basin is not genetically typical for volcanic crater lakes or other common types of volcanic lakes. Nor is it typical for ice-scoured glacial lakes. Instea

Long-Term Follow-Up of Right Ventricle to Pulmonary Artery Biologic Valved Conduits Used in Pediatric Congenital Heart Surgery

Valved conduit reconstruction between the right ventricle (RV) and the pulmonary circulation is often necessary in the surgical treatment of complex congenital heart defects. The aim of this study is to evaluate the long-term performance of the three types of conduits we have used and assess risk factors for conduit failure. Retrospective, single-center review of 455 consecutive pediatric patients

Fault detection in a benchmark simulation model for wastewater treatment plants

The International Water Association (IWA) Benchmark Simulation Models (BSM1 and BSM2) have been successfully used in both industry and academia to test and verify control strategies in wastewater treatment plants (WWTPs). In this study, a new (plant- wide) benchmark simulation model, the BSM2-LT, is developed to evaluate monitoring algorithms. This platform provides opportunities to generate vario

Preattentive facilitation of target trajectories in a dragonfly visual neuron

The ability to pursue targets in visually cluttered and distraction-rich environments is critical for predators such as dragonflies. Previously, we identified Centrifugal Small-Target Motion Detector 1 (CSTMD1), a dragonfly visual neuron likely involved in such target-tracking behaviour. CSTMD1 exhibits facilitated responses to targets moving along a continuous trajectory. Moreover, CSTMD1 competi

Solar and geomagnetic activity reduces pulmonary function and enhances particulate pollution effects

Background: Increased solar and geomagnetic activity (SGA) may alter sympathetic nervous system activity, reduce antioxidant activity, and modulate physiochemical processes that contribute to atmospheric aerosols, all which may reduce pulmonary function. Objectives: Investigate associations between forced expiratory volume at 1 s (FEV1) and forced vital capacity (FVC) with SGA, and assess whether

Nonlocal correlation effects in fermionic many-body systems : Overcoming the noncausality problem

Motivated by the intriguing physics of quasi-two-dimensional fermionic systems, such as high-temperature superconducting oxides, layered transition metal chalcogenides, or surface or interface systems, the development of many-body computational methods geared at including both local and nonlocal electronic correlations has become a rapidly evolving field. It has been realized, however, that the su

Robot-assisted nephroureterectomy for upper tract urothelial carcinoma—feasibility and complications : a single center experience

Background: Robot-assisted nephroureterectomy (RANU) is the primary treatment for upper tract urothelial carcinoma (UTUC) at our hospital for patients with clinical stage less than T2, and for patients with invasive tumours, but unfit for major surgery. Objective: To assess peri-operative conditions and outcomes of RANU at our unit, and to evaluate the safety of the procedure. Methods: The medical

Tremor evaluation using smartphone accelerometry in standardized settings

Tremor can be highly incapacitating in everyday life and typically fluctuates depending on motor state, medication status as well as external factors. For tremor patients being treated with deep-brain stimulation (DBS), adapting the intensity and pattern of stimulation according the current needs therefore has the potential to generate better symptomatic relief. We here describe a procedure for ho

Simultaneous Measurements of Dissolved Organic Carbon and Soil Respiration Reveal Reduced Soil Carbon Loss Under Nitrogen Addition in a Montane Forest

A major uncertainty in the estimation of soils acting as net carbon (C) sinks or sources stem from the effects of anthropogenic nitrogen (N) input on the balance between plant C input and soil C loss. In contrast to the generally observed increasing pattern of plant C input, the response of soil C loss to increased N deposition remains elusive, largely due to its large temporal variation. Here sim

Association of per- and polyfluoroalkyl substances with thyroid homeostasis during pregnancy in the SELMA study

Objectives: To investigate the association of exposure to per- and polyfluoroalkyl substances (PFAS) during early pregnancy with markers of the maternal thyroid system. Methods: Serum concentrations of seven PFAS as well as thyroid stimulating hormone (TSH), free and total thyroxine (FT4 and TT4), free and total triiodothyronine (FT3 and TT3) were measured in pregnant women in early pregnancy in t

The Effects of Transnational Municipal Networks on Urban Climate Politics in the Global South

Transnational municipal networks (TMNs) have emerged as important actors in the global response to climate change. Environmentalists both within and outside governments have placed great expectations and hopes on these networks. Through their novel form of agency, TMNs are expected to provide cities with a form of ‘extra-legem’ empowerment in their responses to climate change. This empowerment is

Conclusion : Towards a ‘Deep Debate’ on the Anthropocene

In this edited volume, we explored the contributions that political science as a discipline can offer to the evolving Anthropocene debate. The term Anthropocene denotes a new geological epoch in the Earth’s history in which humans have become the main drivers of planetary-wide changes. Some authors interpret this as good news, pointing to progress as a result of human ingenuity and the endless pos

A pilot study of methods for prediction of poor outcome by head computed tomography after cardiac arrest

Introduction: In Sweden, head computed tomography (CT) is commonly used for prediction of neurological outcome after cardiac arrest, as recommended by guidelines. We compare the prognostic ability and interrater variability of routine and novel CT methods for prediction of poor outcome. Methods: Retrospective study including patients from Swedish sites within the Target Temperature Management afte

Dual Control by Reinforcement Learning Using Deep Hyperstate Transition Models

In dual control, the manipulated variables are used to both regulate the system and identify unknown parameters. The joint probability distribution of the system state and the parameters is known as the hyperstate. The paper proposes a method to perform dual control using a deep reinforcement learning algorithm in combination with a neural network model trained to represent hyperstate transitions.

Tillitsbaserad styrning - till demokratins försvar

Demokratin kräver en fin väv av normer och strukturer för att kunna fungera. De fria allmänna valen är bara en del av många i denna väv. En annan del är starka och modiga professioner i det offentliga kärnuppdraget. Med sitt omdöme och sin professionella etik utgör dessa grupper en trygghet för våra medborgare och för deras talan i många situationer. Det finns flera skäl till att offentlig styrnin

A modelling study of OH, NO3 and H2SO4 in 2007- 2018 at SMEAR II, Finland : Analysis of long-term trends

Major atmospheric oxidants (OH,O3 and NO3) dominate the atmospheric oxidation capacity, while H2SO4 is considered as a main driver for new particle formation. Although numerous studies have investigated the long-term trend of ozone in Europe, the trends of OH, NO3 and H2SO4 at specific sites are to a large extent unknown. The one-dimensional model SOSAA has been applied in several studies at the S

Noninvasive Assessment of Left Ventricular Pressure-Volume Relations : Inter- and Intraobserver Variability and Assessment Across Heart Failure Subtypes

A novel method to derive pressure-volume (PV) loops noninvasively from cardiac magnetic resonance images has recently been developed. The aim of this study was to evaluate inter- and intraobserver variability of hemodynamic parameters obtained from noninvasive PV loops in healthy controls, subclinical diastolic dysfunction (SDD), and patients with heart failure with preserved ejection fraction, mi

Gut microbiome markers in subgroups of HLA class II genotyped infants signal future celiac disease in the general population : ABIS study

Although gut microbiome dysbiosis has been illustrated in celiac disease (CD), there are disagreements about what constitutes these microbial signatures and the timeline by which they precede diagnosis is largely unknown. The study of high-genetic-risk patients or those already with CD limits our knowledge of dysbiosis that may occur early in life in a generalized population. To explore early gut
