Light-use efficiency (LUE), which quantifies the plants' efficiency in utilizing solar radiation for photosynthetic carbon fixation, is an important factor for gross primary production estimation. Here we use satellite-based solar-induced chlorophyll fluorescence as a proxy for photosynthetically active radiation absorbed by chlorophyll (APARchl) and derive an estimation of the fraction of APARchl

Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. These estimation problems are called minimal problems, and they can often be formulated as systems

The utilization of lignocellulosic biomass to produce biofuels, such as bioethanol, has the potential to provide a sustainable alternative to fossil fuels, and thus mitigate greenhouse gas emissions from the transportation sector.Forest biomass is expected to be a significant source of such biomass, as it can serve as an abundant and sustainable feedstock for bioethanol production. It is unlikely

Background: A hip fracture is a common cause of morbidity, functional disability, and decreased health-related quality of life (HRQOL). With demographic changes showing a growing proportion of older people, hip fractures will be an increasing challenge for healthcare services in the future. Hip fractures threaten the independence of individuals in their everyday lives. In Sweden, more than one thiBackground: A hip fracture is a common cause of morbidity, functional disability, and decreased health-related quality of life (HRQOL).

This thesis proposes a unique quantitative investigation of the long-term development of modern states in Sub-Saharan Africa. This is done by measuring and analysing the dynamic history of tax revenue, as a key measure of the capacity of the state, and development in four countries in francophone West Africa – Benin, Côte d’Ivoire, Niger and Senegal – over the long 20th century. This approach cont

BACKGROUND: Identification of risk factors for rapid joint destruction in early rheumatoid arthritis (RA) can be helpful for optimizing treatment, and improving our understanding of destructive arthritis and its mechanisms. The objective of this study was to investigate the relationship between early RA patient characteristics and subsequent rapid radiographic progression (RRP).METHODS: An incepti

Introduction: Apolipoprotein E (APOE) ε4 is the major genetic risk factor for Alzheimer's disease (AD), but its prevalence is unclear because earlier studies did not require biomarker evidence of amyloid β (Aβ) pathology. Methods: We included 3451 Aβ+ subjects (853 AD-type dementia, 1810 mild cognitive impairment, and 788 cognitively normal). Generalized estimating equation models were used to ass

One of the greatest impediments to the use of probabilistic reasoning in legal arguments is the difficulty in agreeing on an appropriate prior probability for the ultimate hypothesis, (in criminal cases this is normally “Defendant is guilty of the crime for which he/she is accused”). Even strong supporters of a Bayesian approach prefer to ignore priors and focus instead on considering only the lik

This article addresses the question whether maternal mortality should be excluded from the study of excess female mortality. This phenomenon points to lower survival chances for women in certain age groups as opposed to men in the same age group. The existence of excess female mortality has been established for a number of European countries, primarily for the nineteenth century period, and it has

Du kanske simmade i sjön i somras? Bakterier simmar också men i en högviskös värld styrd av mycket exotiska hydrodynamiska egenskaper som får oväntade effekter.

We present high-resolution near-edge X-ray absorption fine structure (NEXAFS) measurements at the P L2/3 edges, F K edge, C K edge, and Se M2/3 edges of the quasi-one-dimensional (1D) conductor and superconductor (TMTSF)2PF6. NEXAFS allows probing the donor and acceptor moieties separately; spectra were recorded between room temperature (RT) and 30 K at normal incidence. Spectra taken around RT we

BRCA1-associated protein 1 (BAP1) is a nuclear deubiquitinating enzyme that is associated with multiprotein complexes that regulate key cellular pathways, including cell cycle, cellular differentiation, cell death, and the DNA damage response. In this study, we found that the reduced expression of BAP1 pro6motes the survival of neuroblastoma cells, and restoring the levels of BAP1 in these cells f

Recently, we identified ELL2 as a susceptibility gene for multiple myeloma (MM). To understand its mechanism of action, we performed expression quantitative trait locus analysis in CD138+ plasma cells from 1630 MM patients from four populations. We show that the MM risk allele lowers ELL2 expression in these cells (P combined = 2.5 × 10-27; β combined = -0.24 SD), but not in peripheral blood or ot
