Under sustained global warming, Arctic climate is projected to become more responsive to changes in North Pacific meridional heat transport as a result of teleconnections between low and high latitudes, but the underlying mechanisms remain poorly understood. Here, we reconstruct subarctic humidity changes over the past 400 kyr to investigate the role of low-to-high latitude interactions in regulat
The Unified Glare Rating (UGR) method defined by the International Commission on Illumination is practically the only one used for evaluation of discomfort glare in the lighting design process. However, it is unclear if this method aligns with subjective discomfort glare measures using subjective glare indexes (SGIs). We compared calculated UGR values with commonly used subjective discomfort glare
Shallow lakes worldwide face escalating pressures from eutrophication and climate change, yet comprehensive monitoring of Chlorophyll-a (Chl-a) spatiotemporal dynamics remains challenging due to the high costs and logistical constraints of traditional sampling approaches across large, heterogeneous water bodies. Lake Balaton, a large shallow lake system (80 km long, 7 km wide, 3.7 m mean depth) in
Although spatial resolution in fluorescence microscopy and related fields has advanced to the nanometer scale, time resolution has remained essentially unchanged and is set by the camera system’s imaging time. Yet adequate time resolution is crucial for information acquisition about, for instance, dynamical processes in cells. This acquisition typically proceeds by analyzing biomolecular trajector
Understanding greenhouse gas fluxes in semi-arid ecosystems is critical for improving our understanding of biogeochemical cycles, particularly in underrepresented regions like the African Sahel. In these landscapes, greenhouse gas exchange arises from ground, trees, and water ponds, and is further shaped by environmental conditions and grazing. The carbon dioxide, methane, and nitrous oxide fluxes
This paper is concerned with a recently proposed scalable protocol for vehicle platooning, known as the serial consensus protocol. This achieves coordination of second-order integrator systems through a series connection of first-order conventional consensus protocols, and has been theoretically shown to have advantageous stability and performance properties. We implement this protocol on a vehicl
Transpiration drives up to 40 % of terrestrial precipitation, with forests playing a critical role. This study combines long-term sap flow measurements and surface-based cloud observations to examine how different clouds affect tree transpiration across boreal and temperate European forests. Under specific cloudy conditions, sap flow can exceed clear-sky levels, reflecting distinct radiation effec
This paper studies cone-preserving linear discrete-time switched systems whose switching is governed by an automaton. For this general system class, we present performance analysis conditions for a broadly usable performance measure. In doing so, we generalize several known results for performance and stability analysis for switched and positive switched systems, providing a unifying perspective.
The mountain front recharge (MFR) process significantly influences the movement of water and dissolved organic carbon (DOC) in alpine catchments. However, no existing watershed models can adequately simulate this process, hindering accurate quantification of streamflow and DOC dynamics. To address this gap, this study explicitly incorporated the MFR process into a watershed-scale integrated water–
We propose a method for estimating the 3D position of a target point, given multiple measurements of it, using mm-wave radar data. Given azimuth headings and range estimates from posed radar positions, we find the 3D position, using an approximate, but geometrically and statistically meaningful cost. The 3D position is found in an optimal way, using this approximate cost. By deriving the Lagrangia
We perform a validation analysis on the multipolar model of opinion dynamics. A general methodology for using the model on datasets of two correlated variables is proposed and tested using data on the relationship between COVID-19 vaccination rates and political participation in Sweden. The model is shown to successfully capture the opinion segregation demonstrated by the data and spatial correlat
The purpose of this thesis is to analyse the identity of the Chilean environmental movement in relation to the Chilean nation-state. The theme is discussed through theories of social constructivism, identity and social movements. Of central focus is to discuss the role of the environmental movement in constructing environmental policy and in relation to national identity. The thesis draws on empir
INTRODUCTION: Worsening renal function (WRF) is associated with poor prognosis in patients with heart failure (HF). Osteopontin (OPN) and Matrix extracellular phosphoglycoprotein (MEPE) are expressed in the kidneys and are involved in bone mineralization processes. Higher OPN levels have been associated with a higher risk for adverse outcomes in patients with chronic kidney disease (CKD), and MEPE
Background: Children aged 0–18 years who need long-term respiratory support rely on medical technology and comprehensive medical care. For this care to be provided at home, access to medical and social support and care is essential. In Sweden, the most notable form is personal care assistance (PCA), which is granted based on legislation and individual authority decisions. We aim to explore the imp
Objective: Several surgical approaches are being used in the reconstruction of long-gap esophageal atresia. We investigated which methods are being used in the Nordic countries and the postoperative complications that occurred in the first year of life. Methods: This study is a retrospective multicenter study, where medical records on children with esophageal atresia Gross type C or D born in the
This study seeks to explore the pragmaticalization process of (it's) no biggie, through a corpus-based taxonomical and statistical examination. The research study involves (i) elaborating a taxonomy of no biggie constructions by exploring the variability of the pragmatic functions and the syntactic features associated with the construction; (ii) monitoring the links between the taxonomical types o
The handover (HO) procedure is one of the most critical functions in a cellular network driven by measurements of the user channel of the serving and neighboring cells. The success rate of the entire HO procedure is significantly affected by the preparation stage. As massive Multiple-Input Multiple-Output (MIMO) systems with large antenna arrays allow resolving finer details of channel behavior, w
Background: Telemedicine innovations are rarely adopted into routine health care, the reasons for which are not well understood. Teleguidance, a promising service for remote surgical guidance during endoscopic retrograde cholangiopancreatography (ERCP) was due to be scaled up, but there were concerns that user attitudes might influence adoption. Objective: Our objective was to gain a deeper unders
Ground-level ozone (O3), formed via complex photochemistry involving nitrogen oxides (NOx) and volatile organic compounds (VOCs), is a critical secondary pollutant and oxidant. Therefore, understanding whether the formation of O3 is NOx- or VOC-limited is essential for effective air quality management. Recently, we demonstrated that the distribution of highly oxygenated organic molecules (HOMs) ca
Based on an ethnographic survey of the 26th Conference of the United Nations Framework Convention on Climate Change, this article analyses the ways in which youth participate in climate negotiations. We show how youth actors are characterised by diverse modes of engagement, and particular sociodemographic anchors. Presenting themselves as the voice of youth worldwide, youth actors have gradually c
