Forest leaf area index (LAI), is an important variable in carbon balance models. However, understory vegetation is a recognized problem that limits the accuracy of sate I lite-estimated forest LAI. A canopy reflectance model was used to investigate the impact of the understory vegetation on LAI estimated from reflectance values estimated from satellite sensor data. Reflectance spectra were produce
Calbindin D-28k, a highly conserved protein with Ca2+-sensing and Ca2+-buffering capabilities, is abundant in brain and sensory neurons. This protein contains six EF-hand subdomains, four of which bind Call with high affinity. Calbindin D28k can be reconstituted from six synthetic peptides corresponding to the six EF-hands, indicating a single-domain structure with multiple interactions between th
Forest structure is a key driver of forest functional processes. The characterization of forest structure across spatiotemporal scales is essential for forest monitoring and management. LiDAR data have proven particularly useful for cost-effectively estimating forest structural attributes. This paper evaluates the ability of combined forest inventory data and low-density discrete return airborne L
Background. Flecainide is a first-line rhythm control treatment for patients with atrial fibrillation (AF), however long-term treatment outcomes are understudied. Objective. To investigate associations of electro- (ECG) and echocardiographic indices with safety and efficacy outcomes of long-term flecainide treatment for recurrent AF. Methods. Consecutive patients with AF admitted for in-hospital f
This paper presents a search for physics beyond the Standard Model targeting a heavy resonance visible in the invariant mass of the lepton-jet system. The analysis focuses on final states with a high-energy lepton and jet, and is optimised for the resonant production of leptoquarks — a novel production mode mediated by the lepton content of the proton originating from quantum fluctuations. Four di
Frataxin is a highly conserved protein found in both prokaryotes and eukaryotes. It is involved in several central functions in cells, which include iron delivery to biochemical processes, such as heme synthesis, assembly of iron-sulfur clusters (ISC), storage of surplus iron in conditions of iron overload, and repair of ISC in aconitase. Frataxin from different organisms has been shown to undergo
Background: Quantitative magnetic resonance imaging (MRI), e.g. relaxation parameter mapping, may be sensitive to structural and compositional tissue changes, and could potentially be used to non-invasively detect and monitor early meniscus degeneration related to knee osteoarthritis. Objective: To investigate MR relaxation times as potential biomarkers for meniscus degeneration through comparison
ABSTRACT: Neuroinflammation is implicated in the development and maintenance of persistent pain states, but there are limited data linking cerebrospinal fluid (CSF) inflammatory mediators with neurophysiological pain processes in humans. In a prospective observational study, CSF inflammatory mediators were compared between patients with osteoarthritis (OA) who were undergoing total hip arthroplast
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint objects, a flexibly-pointed instrument capable of high astrometric accuracy is an ideal complement to current astrometric surveys and a unique tool for precision astrophysics. Such a space-based mission will push the front
Labeling of proteins with deuterium (2H) is often necessary for structural biology tech-niques, such as neutron crystallography, NMR spectroscopy, and small-angle neutron scattering. Perdeuteration in which all protium (1H) atoms are replaced by deuterium is a costly process. Typ-ically, expression hosts are grown in a defined medium with heavy water as the solvent, which is supplemented with a de
Peanut (Arachis hypogaea L.) is an important oilseed crop worldwide, and peanut height has been shown to be closely related to yield, therefore a better understanding of the genetic base of plant height-related traits may allow us to have better control of crop yield. Plant height-related traits are quantitative traits that are genetically controlled by many genes, and distinct quantitive trait lo
Background: The demographic change affects the retirement age, which has been postponed in many countries. Therefore, the number of senior employees is increasing in the world. However, managers’ attitudes towards their employees’ employability affect the employees’ possibilities regarding whether they can and want to work. Objective: The aim of this study was to evaluate managers’ attitudes towar
This is presentation of a research project that investigates the learning and teaching of Swedish folk music as it unfolds across different contexts of transmission. Studies have shown that spaces for the transmission of Swedish folk music involves many aspects of social life (von Wachenfeldt, 2015, Eriksson, 2017, Eriksson, 2019). At the same time other pragmatic factors frame the transmission ta
BACKGROUND AND OBJECTIVES: Several pathologic processes might contribute to the degeneration of the cholinergic system in aging. We aimed to determine the contribution of amyloid, tau, and cerebrovascular biomarkers toward the degeneration of cholinergic white matter (WM) projections in cognitively unimpaired individuals. METHODS: The contribution of amyloid and tau pathology was assessed through
Finansieringen av nationella vetenskapliga tidskrifter har blivit ett lömskt problem eller ett wicked problem inte bara för historia utan för humaniora i stort. Liksom andra lömska problem utmärks denna fråga av att själva problembeskrivningen är föränderlig, definitionerna undflyende samt att problemet är sammanvävt med andra komplexa problemområden. För en långsiktig lösning är det därför nödvänThe question of how to fund Swedish academic journals such as Scandia has become a wicked problem, not only for history but also for the humanities as a whole. This issue is confounded by the difficulty in terms of categorizing these journals and their funding needs and further complicated by the global movement towards open access. For the humanities, the issue of how to fund these journals is of
Amyloid formation is linked to devastating neurodegenerative diseases, motivating detailed studies of the mechanisms of amyloid formation. For Aβ, the peptide associated with Alzheimer’s disease, the mechanism and rate of aggregation have been established for a range of variants and conditions in vitro and in bodily fluids. A key outstanding question is how the relative stabilities of monomers, fi
Resilience in tourism studies has mainly departed from a socio-ecological system-theory approach and has developed knowledge in relation to different tourism contexts. This approach has consequences for the conceptualization of resilience and sets limits. Calls for theory development on resilience see a need to take account of, for instance, politics and power relations, and conflicts over resourc
BACKGROUND: Atraumatic localized convexity subarachnoid hemorrhage (cSAH) is an uncommon form of nonaneurysmal subarachnoid hemorrhage characterized by bleeding limited to the cerebral convexities. Ipsilateral cSAH can result from a variety of causes, such as internal carotid artery stenosis, obstruction, and dissection, although concomitant contralateral cSAH is exceptionally rare. In this case,
In order to change consumption patterns into something that is more sustainable, it is essential that we consider the various and conflicting meanings clothes have in people's lives. This article presents an analysis of diaries written by consumers of different ages and occupations over a period of three months in 2015. These consumers documented their clothing and shoe purchases, took inventory o
The effects of fuel properties on the performance and emissions of an engine running in partially premixed combustion mode were investigated using nine test fuels developed in the gasoline boiling point range. The fuels covered a broad range of ignition quality and fuel chemistry.The fuels were characterized by performing a load sweep between 1 and 12 bar gross IMEP at 1000 and 1300 rpm. A heavy d
