In this thesis, we model stochastic processes in time and space. We focus on the processes whose covariance structure is either changing over the time span, or depends on the location in space. We develop models that appropriately describe and analyze such data behaviors in various different fields including finance, economics and engineering. This thesis begins with an introductory section which

This paper provides exact analysis of a model for sustainable control of a one-warehouse-N-retailer inventory system with time based shipment consolidation. The model is motivated by discussions with industry, and involves the possibility to reserve intermodal transportation capacity in combination with truck transports available on demand. Inventories are reviewed continuously while shipments fro

Objective: The individual enabling and support (IES) model was effective in gaining competitive employment for people with affective disorders compared with traditional vocational rehabilitation (TVR) services in a randomized controlled trial in a Swedish setting. The object of this study is to perform a cost-effectiveness analysis of IES comparing to TVR. Methods: We considered the costs of inter

Aim: Target temperature management (TTM) at 32-36 °C is recommended in unconscious survivors of cardiac arrest. This study reports awakening in the TTM-trial. Our predefined hypotheses were that time until awakening correlates with long-term neurological outcome and is not affected by level of TTM. Methods: Post-hoc analysis of time until awakening after cardiac arrest, its association with long-t

Background: Person-centred care (PCC) is considered a key component of effective illness management and high-quality care. However, the PCC concept is underdeveloped in outpatient care. In rheumatology, PCC is considered an unmet need and its further development and evaluation is of high priority. The aim of the present study was to conceptualize and operationalize PCC, in order to develop an inst

Background: Influenza is responsible for substantial morbidity and mortality, but there is limited information on reliable disease burden estimates, especially from middle-income countries in the WHO European Region. Objectives: To estimate the incidence of medically attended influenza-associated influenza-like illness (ILI) and hospitalizations due to severe acute respiratory infection (SARI) pre

In this study, numerical simulations are performed to investigate the effect of dimple location on the flow structure and heat transfer characteristics in a 90°-turned channel with pin fins. Results of the flow structure, heat transfer on the endwall, and friction factor are included in this study. It is found that the dimple location has an impact on the flow structure and heat transfer both for

Background: Regimens based on ibrutinib alone and lenalidomide and rituximab in combination show high activity in patients with relapsed or refractory mantle cell lymphoma. We hypothesised that the combination of all three drugs would improve efficacy compared with previously published data on either regimen alone. Methods: In this multicentre, open-label, single-arm, phase 2 trial, we enrolled pa

BACKGROUND: Numerous studies have reported a strong association between temperature and mortality. Additional insights can be gained from investigating the effects of temperature on years of life lost (YLL), considering the life expectancy at the time of death. OBJECTIVES: The goal of this work was to assess the association between temperature and YLL at seven low-, middle-, and high-income sites.

I denna artikel diskuteras de nordiska historikermötena på 1920-talet. Motsättningar mellan de så kallade historisk-kritiska historikerna (Arup och Wiebull) å ena sidan och mer samarbetsorienterade historiker (Friis och Koht) å den andra diskuteras och tolkas utifrån begreppet vetenskaplig persona. Även synen på det nationella kontra det internationella behandlas.

Although Iran’s Ghaen Plain provides saffron to much of the world, no regional groundwater quality (GQ) assessment has yet been undertaken. Given the region’s potential for saltwater intrusion and heavy metal contamination, it is important to assess the GQ and determine its main probable source of pollution (MPSP). Such knowledge would allow for informed mitigation or elimination of the potential

The etiology of interstitial cystitis/bladder pain syndrome (IC/BPS) remains elusive and may involve multiple causes. To better understand its pathophysiology, many efforts have been made to create IC/BPS models. Most existing models of IC/BPS strive to recreate bladder-related features by applying noxious intravesical or systemic stimuli to healthy animals. These models are useful to help underst

Osteogenesis imperfecta (OI) is a strikingly heterogeneous group of disorders with a broad range of phenotypic variations. It is also one of the differential diagnoses in bent bone dysplasias along with campomelic dysplasia and thanatophoric dysplasia and can usually be distinguished by decreased bone mineralization and bone fractures. Bent bone dysplasias also include syndromes such as kyphomelic

Objectives: The aim of the present study was to validate the Swedish version of the educational needs assessment tool (SwENAT) in undifferentiated spondyloarthritis (USpA) and use it to study the educational needs of patients with USpA. Methods: This was a cross-sectional study, recruiting a random sample of patients with USpA from a hospital register in Sweden. Educational needs data were collect
