Stomatal conductance (g(s)) is a key land-surface attribute as it links transpiration, the dominant component of global land evapotranspiration, and photosynthesis, the driving force of the global carbon cycle. Despite the pivotal role of g(s) in predictions of global water and carbon cycle changes, a global-scale database and an associated globally applicable model of g(s) that allow predictions
We report on the synthesis of ferromagnetic manganese arsenide (MnAs) nanoparticles via the conversion of primary Mn particles which are generated in an aerosol process in a spark discharge generator. After sintering and size selection in an aerosol setup, the particles are deposited on GaAs(100) B and Si(111) substrates. Subsequent conversion to MnAs particles takes place in an annealing process
To compare the internal computer-based scoring with human-based video scoring of cataract modules in the Eyesi virtual reality intraocular surgical simulator, a comparative case series was conducted at the Department of Clinical Sciences - Ophthalmology, Lund University, Skåne University Hospital, Malmö, Sweden.
The frequency dependence of the longitudinal relaxation rate, known as the magnetic relaxation dispersion (MRD), can provide a frequency-resolved characterization of molecular motions in complex biological and colloidal systems on time scales ranging from 1 ns to 100 μs. The conformational dynamics of immobilized proteins and other biopolymers can thus be probed in vitro or in vivo by exploiting i
We report on an x-ray diffraction (XRD) study of helical poly[9,9-bis(2-ethylhexyl)fluorene] (PF2/6) under high quasihydrostatic pressure and show an effect of pressure on the torsion angle (dihedral angle) between adjunct repeat units and on the hexagonal unit cell. A model for helical backbone conformation is constructed. The theoretical position for the most prominent 00l x-ray reflection is ca
The lysine-specific crosslinker 3,3'-dithiobis(sulfosuccinimidylpropionate) (DTSSP) is commonly used in the structural characterization of proteins by chemical crosslinking and mass spectrometry and we here describe an efficient two-step LC-MALDI-TOF/TOF procedure to detect crosslinked peptides. First MS data are acquired, and the properties of isotope-labeled DTSSP are used in data analysis to id
Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and form of C released to the atmosphere in a warmer world will influence the strength of the permafrost C feedback to climate change. We used a survey to quantify variability in the perception of the vulnerability of permafros
A system for naming ribosomal proteins is described that the authors intend to use in the future. They urge others to adopt it. The objective is to eliminate the confusion caused by the assignment of identical names to ribosomal proteins from different species that are unrelated in structure and function. In the system proposed here, homologous ribosomal proteins are assigned the same name, regard
We aimed at assessing familial risk of melanoma by considering a detailed family history of multiple primary (invasive/in situ) melanomas (MPM), stratified by histology and location.
OBJECTIVE: To describe and enhance our understanding of how persons with late effects of polio experience the influence of an interdisciplinary rehabilitation programme. PARTICIPANTS: Twelve persons with clinically verified late effects of polio who had participated in an individualized, goal-oriented, comprehensive interdisciplinary rehabilitation programme. METHODS: Qualitative research intervie
Coding principles are central to understanding the organization of brain circuitry. Sparse coding offers several advantages, but a near-consensus has developed that it only has beneficial properties, and these are partially unique to sparse coding. We find that these advantages come at the cost of several trade-offs, with the lower capacity for generalization being especially problematic, and the
Extracellular vesicle (EV)-mediated intercellular transfer of signaling proteins and nucleic acids has recently been implicated in the development of cancer and other pathological conditions; however, the mechanism of EV uptake and how this may be targeted remain as important questions. Here, we provide evidence that heparan sulfate (HS) proteoglycans (PGs; HSPGs) function as internalizing recepto
The proteoglycan NG2 plays a major role in proliferation, migration, and differentiation of pericytes and NG2 cells in the brain. We have previously reported decreased NG2 levels in cerebrospinal fluid (CSF) from patients with Alzheimer's disease (AD) and a relationship between NG2 and AD biomarkers in these patients. To further investigate whether alterations in NG2 is specific to AD pathology, w
The use of antineoplastic drugs in health care steadily increases. Health care workers can be occupationally exposed to antineoplastic drugs classified as carcinogenic or teratogenic. Monitoring of surface contamination is a common way to assess occupational exposure to antineoplastic drugs, since wipe sampling is used as a surrogate measure of dermal exposure. Since no occupational limits for ant
OBJECTIVES: To evaluate the proportion of cardiovascular disease (CVD) incidence that is explained by genetic variation at chromosome 9p21 and to test whether such variation adds incremental information with regard to CVD prediction, beyond traditional risk factors. DESIGN, SETTING AND PARTICIPANTS: rs4977574 on chromosome 9p21 was genotyped in 24 777 subjects from the Malmö Diet and Cancer study
JavaScript is a dynamically typed, object-based scripting language with runtime evaluation. It has emerged as an important language for client-side computation of web applications. Previous studies indicate some differences in execution behavior between established benchmarks and real-world web applications. Our study extends previous studies by showing some consequences of these differences. We c
This work presents a new inclusive search for supersymmetry (SUSY) by the ATLAS experiment at the LHC in proton-proton collisions at a center-of-mass energy root s = 7 TeV in final states with jets, missing transverse momentum and one or more isolated electrons and/or muons. The search is based on data from the full 2011 data-taking period, corresponding to an integrated luminosity of 4.7 fb(-1).
Using a large, new database of contractual provisions governing the allocation of cash flow rights in venture capital (VC) financings, we investigate how contract design is related to VC abilities to monitor and provide value-added services to the entrepreneur. We find that more experienced VCs, who have superior abilities and more frequently join the boards of their portfolio companies, obtain we
