Wetland types and soil properties shape microbial communities in permafrost-degraded swamps

Global warming has accelerated permafrost degradation, destabilizing soil organic carbon (SOC) in wetlands. Soil microorganisms play a crucial role in SOC decomposition. Despite increasing studies on soil microorganisms and their associated impacts on SOC decomposition in wetlands, few studies have simultaneously investigated the impacts of soil physical properties and nutrient stoichiometry on so

SRPNet : stroke risk prediction based on two-level feature selection and deep fusion network

Background: Stroke is one of the major chronic non-communicable diseases (NCDs) with high morbidity, disability and mortality. The key to preventing stroke lies in controlling risk factors. However, screening risk factors and quantifying stroke risk levels remain challenging. Methods: A novel prediction model for stroke risk based on two-level feature selection and deep fusion network (SRPNet) is

A new implementation of FLEXPART with Enviro-HIRLAM meteorological input, and a case study during a heavy air pollution event

We integrated Enviro-HIRLAM (Environment-High Resolution Limited Area Model) meteorological output into FLEXPART (FLEXible PARTicle dispersion model). A FLEXPART simulation requires meteorological input from a numerical weather prediction (NWP) model. The publicly available version of FLEXPART can utilize either ECMWF (European Centre for Medium-range Weather Forecasts) Integrated Forecast System

Isolation, Behavioral Identification, and Pathogenicity Assessment of Entomopathogenic Fungi from a Forest Wood Borer

Forest wood borers (FWB) cause severe tree damage and economic losses worldwide. The release of entomopathogenic fungi (EPF) during the FWB emergence period is considered an acceptable alternative to chemical control. However, EPF resources have been significantly less explored for FWBs, in contrast to agricultural insect pests. This paper presents a protocol for exploring EPF resources from FWBs

Comparison of Humidified Hydrogen and Partly Pre-Reformed Natural Gas as Fuel for Solid Oxide Fuel Cells applying Computational Fluid Dynamics

A three-dimensional computational fluid dynamics (CFD) approach based on the finite element method (FEM) is used to investigate a solid oxide fuel cell (SOFC). Governing equations for heat, gas-phase species, electron, ion and momentum transport are implemented and coupled to kinetics describing electrochemical as well as internal reforming reactions. The model cell design is based on a cell from

Modeling the seasonality of carbon, evapotranspiration and heat processes for cold climate conditions TRITA-LWR LIC 2054. Licentiate Thesis in Land and Water Resources Engineering. KTH Architecture and the Built Environment, Stockholm

The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this

Essays on stochastic volatility

Popular Abstract in Swedish Avhandlingen består av fem stycken artiklar som analyserar och estimerar finansiella prisprocesser. Alla artiklarna handlar också om stokastiska volatilitetsprocesser som estimeras med Bayesiansk statistik och Markov Chain Monte Carlo (MCMC) metoder. Det första pappret utvecklar en modell för att mäta den amerikanska och de regionala europeiska aktiemarknadernas påverkThis dissertation consists of five papers concerned with the estimation and analysis of financial price processes. The first paper develops a stock price model and analyzes the impact of the US and the regional European stock markets on the local European countries’ stock markets. Among several things, we find that the dependencies among the stock markets do not increase during periods of distress

Increase in upper tropospheric and lower stratospheric aerosol levels and its potential connection with Asian pollution

Satellite observations have shown that the Asian Summer Monsoon strongly influences the upper troposphere and lower stratosphere (UTLS) aerosol morphology through its role in the formation of the Asian Tropopause Aerosol Layer (ATAL). Stratospheric Aerosol and Gas Experiment II solar occultation and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) lidar observations show

Permian continental paleoenvironments in Southeastern Asia: New insights from the Luang Prabang Basin (Laos)

In Laos (Southeastern Asia), Late Paleozoic sediments were identified by early French explorations across Indochina during the late 19th century (Pavie missions), but little work was undertaken to characterize the sedimentological and stratigraphical context until now. From detailed sedimentological and paleontological studies, we propose an interpretation of the depositional environment and of th

Knowledge Sharing Across Borders - A Study in the IKEA World

To enter new markets is not easy. The most obvious challenge, at least judging from the majority of literature on internationalization, is to understand the new market thus taking a market(ing) perspective. External aspects of internationalization are often stressed, while internal aspects, focusing on why organizations fail, are less developed or examined. In order to better understand the intern

Long term NOAA-AVHRR GIMMS-NDVI - rainfall relationships and trends 1981 to 2003 for entire DeSurvey area of interest

The paper presents results of a study on the use of the NOAA AVHRR data for desertification monitoring on a regional-global level. It is based on processing of the GIMMS 8 km global NDVI data set. Time series of annual integrated NDVI and standardized annual NDVI anomalies from the 1981-2003 periodic means were compared with a corresponding rainfall data set (i.e. 1981-2003) as well as a historica

The Top Runner policy concept: Pass it down?

In the 1990s, Japanese energy regulators were concerned by the fact that new generations of energy using appliances and products no longer displayed successive use-phase energy efficiency improvements, such as those that characterised product development in Japan after the 1970s oil crises. Therefore, in 1999, Japan incepted its Top Runner programme, designed to rejuvenate the lost momentum. Sever

Country of ownership change in the premium segment : consequences for brand image

Purpose: This paper aims to explore how the ownership transfer from a highly industrialised country to less industrialised countries influences consumers’ brand perceptions. Design/methodology/approach: Three acquisition cases of premium car brands (Jaguar, Land Rover and Volvo) are investigated using qualitative data from online brand communities. Findings: When country of ownership (COOW) for br

Global outsourcing of carbon emissions 1995–2009: A reassessment

Increasing global production fragmentation allows for outsourcing of emissions, which may undermine national climate policies. Researchers focusing on the gap between consumption-based and production-based emissions have concluded that developed countries are systematically outsourcing emissions to developing countries. However, asymmetries in emissions embodied in trade may emerge due to differen
