During the last years the amount of electricity generated by Distributed Energy Resources (DER), especially wind turbines, has been increasing a lot. These Distributed Generation (DG) units are often connected to rural distribution networks, where they have a large impact on the voltage and the network losses. The network voltage at the customers point of connection is an important quality criteri
Most parametric fundamental frequency estimators make the implicit assumption that any corrupting noise is additive, white Gaus-sian. Under this assumption, the maximum likelihood (ML) and the least squares estimators are the same, and statistically efficient. However, in the coloured noise case, the estimators differ, and the spectral shape of the corrupting noise should be taken into account. To
One feature of global change is that biota must respond not to single, but to multiple environmental drivers. By growing a model photosynthetic microbe in environments containing between one and eight different drivers, including changes in CO 2, temperature, and pH, in different combinations, we show that the number as well as the identities of drivers explain shifts in population growth rates. T
IntroductionMulti‐component T2 mapping using a gradient‐ and spin‐echo (GraSE) acquisition has become standard for myelin water imaging at 3 T. Higher magnetic field strengths promise signal‐to‐noise ratio benefits but face specific absorption rate limits and shortened T2 times. This study investigates compartmental T2 times in vivo and addresses advantages and challenges of multi‐component T2 map
The terrestrial carbon cycle is an important component of the global carbon budget due to its large gross exchangefluxes with the atmosphere and their sensitivity to climate change. Terrestrial biosphere models showlarge uncertainties in simulating carbon fluxes, which impact global carbon budget assessments. The land surfacecarbon cycle is tightly controlled by soil moisture through plant physiol
Long charge carrier diffusion length and large grain size are commonly believed to be inherent properties of highly luminescent polycrystalline thin-film semiconductors. However, exactly these two properties make luminescence very susceptible to quenching by just one strongly quenching defect state if present in each grain. Moreover, when the number of quenchers per grain is small (say 1–10), it v
Background: Concerns about the cardiovascular safety of medications used for the treatment of attention-deficit hyperactivity disorder (ADHD) remain. We aimed to compare the effects of pharmacological treatments for ADHD on haemodynamic values and electrocardiogram (ECG) parameters in children, adolescents, and adults. Methods: For this systematic review and network meta-analysis, we searched 12 e
BACKGROUND: Women with intellectual disabilities face significant barriers to gynecological, reproductive, antenatal, and perinatal care, which may adversely impact maternal and fetal health. Previous research indicates increased risks for gestational diabetes, pre-eclampsia, caesarean birth, preterm birth, and other complications in pregnant women with intellectual disabilities. However, studies
Dopamine and serotonin are two major monoamine neurotransmitters associated with Parkinson's disease (PD), but their spatial distribution and relationship to underlying functional brain architecture are not fully understood. We assessed 30 patients with PD at baseline using structural MRI, resting-state functional MRI (rs-fMRI), 11C-PE2I and 11C-DASB PET, along with comprehensive clinical evaluati
The climate crisis calls for a new generation of social policy compatible with planetary limits and economic postgrowth circumstances. This article analyses how some of the pillars of such a new generation of social policy may be conceptualized by highlighting commonalities between the most recent IPCC report and the sustainable welfare literature. Methodologically triangulating content analysis o
This study investigated the dosimetric impact of uncompensated motion and motion compensation with dynamic multileaf collimator (DMLC) tracking for prostate intensity modulated arc therapy. Two treatment approaches were investigated; a conventional approach with a uniform radiation dose to the target volume and an intraprostatic lesion (IPL) boosted approach with an increased dose to a subvolume o
Diffusion of water through membranes presents a considerable challenge, as the diffusivity often depends on the local concentration of water. One particular example with strong biological relevance is the stratum corneum (SC) as the primary permeability barrier for the skin. A simple alternative for the constant diffusivity model is provided by the Fujita’s two-parameter rational approximation, wh
Among the hundreds of known hot Jupiters (HJs), only five have been found to have companions on short-period orbits. Within this rare class of multiple planetary systems, the architecture of WASP-47 is unique, hosting an HJ (planet-b) with both an inner and an outer sub-Neptunian mass companion (-e and -d, respectively) as well as an additional non-transiting, long-period giant (-c). The small per
Objectives To analyse potential biomarkers for vibration-induced nerve damage in a population-based, observational study. Design Prospective cohort study. Setting Malmö Diet Cancer Study (MDCS), Malmö, Sweden. Participants In a subcohort of 3898 individuals (recruited 1991-1996) from MDCS (baseline examination in 28 449 individuals; collection of fasting blood samples in a cardiovascular subcohort
The current concept of social resilience, which developed from the classic definition of resilience, neglects social resilience as a social phenomenon including social experiences and practices in the face of change and adversity. I argue that framing social resilience as a capacity or ability undermines its characteristics as a complex and contextualized social phenomenon that contributes to adap
