This study investigates isoprene emissions in a high-latitude Alpine tundra ecosystem, focusing on using near-field remote sensing of surface temperatures, the photochemical reflectance index (PRI) and normalized difference vegetation index (NDVI), and meteorological measurements to model these emissions. Isoprene is a key biogenic volatile organic compound (BVOC) emitted by select plants, which c
Plant macrofossil and pollen records from the partially varved sediments of Lake Odensjön in southernmost Sweden provide detailed information on local forest development and land-use history within Söderåsen National Park during the past 600 years. A relatively dense forest dominated by Fagus (European beech) covered the steep talus-dominated slopes surrounding the lake during at least a century p
A search for long-lived particles (LLPs) using Formula Presented of Formula Presented collision data with Formula Presented recorded by the ATLAS experiment at the LHC is presented. The search targets LLPs with masses between 5 and 55 GeV that decay hadronically in the ATLAS inner detector. Benchmark models with LLP pair production from exotic decays of the Higgs boson and models featuring long-li
Two 2 x 10-year climate change experiments made with the Rossby Centre regional Atmospheric climate model (RCA) are reported. These two experiments are driven by boundary data from two global climate change simulations, one made with HadCM2 and the other with ECHAM4/OPYC3, in which the global mean warning is virtually the same, 2.6°C. The changes in mean temperature and precipitation show similari
Although many efforts have been made to eliminate barriers in public transport worldwide, research shows that public transport is still often perceived as challenging, inconvenient, and inaccessible for many people with disabilities. A growing body of research points to several issues, relating to the spatial and temporal distribution of public transport, affordability, safety, and social barriers
BACKGROUND: Selective glomerular hypofiltration syndrome (SGHS), formerly shrunken pore syndrome, an emerging marker of glomerular dysfunction, is associated with worsened prognosis in cardiovascular disease, but its role in kidney failure remains underexplored. Osteopontin (OPN) is associated with worsening kidney function and prognosis in chronic kidney disease.PURPOSE: To explore if increased l
Date palm oases in North Africa have historically supported agriculture through indigenous irrigation techniques such as foggaras and tabias, made possible by a relatively stable water supply. However, the sustainability of these systems is increasingly threatened by irrational water use, climate change and environmental resources degradation. In response to these challenges, we introduced and eva
The effects of possible climate changes on a cold attic performance are considered in this work. The hygro-thermal responses of the attic to different climate data conditions are simulated using a numerical model, which has been made using the IBPT. Cold attic, which is the most exposed part of the building to the environment, is classified as a risky construction in Sweden. Mould growth on intern
This paper analyzes the I/Q imbalance effect of direct-conversion receiver in wide-band wireless communication system and sets up frequency-selective I/Q imbalance model for ultra-wide band system. We design a new training sequence based on extra phase rotation and propose an estimation algorithm using diversity message introduced by I/Q imbalance during the demodulation process. Theoretical analy
Two different factor V cDNA fragments were used as hydridization probes in the chromosomal assignment of the human and rat factor V genes. A 1.6-kb EcoRI fragment was used as a hybridization probe to analyze a panel of human-rodent somatic cell hybrids. Cosegregation of factor V specific DNA restriction fragments with human chromosome 1 was observed. In addition, a panel of rat-mouse somatic cell
By using a three dimensional computational method, gas flow and heat transfer have been investigated and analyzed for both cathode / anode ducts of proton exchange membrane fuel cells. The Brinkman- Forchheimer-extended Darcy model is employed to investigate the flow inside the porous layer of the duct. Effects of inertial coefficient, together with permeability, effective thermal conductivity, th
Prior work on multi-view structure from motion is dominated by sequential approaches starting from a single two-view reconstruction, then adding new images one by one. In contrast, we propose a non-sequential methodology based on rotational consistency and robust estimation using convex optimization. The resulting system is more robust with respect to (i) unreliable two-view estimations caused by
In many areas, the ability to create accurate 3D models is of great interest, for example, in computer vision, robotics, architecture, and augmented reality. In this paper we show how a textured indoor environment can be reconstructed in 3D using an RGB-D camera. Real-time performance can be achieved using a GPU. We show how the camera pose can be estimated directly using the geometry that we repr
How human exposure levels of air pollutants are related to health status is an issue of great importance for e.g. infrastructural and urban planning. This study analysed the exposure levels of NO2 for individuals depending on their country of birth. The study was conducted within three different study areas of varying characteristics and extent to decide whether any such associations existed and i
