Many model-based tuning methods for PI(D) controllers, especially - but not exclusively - in the process control domain, employ models with delay. Doing so has advantages, basically in terms of tuning rules' simplicity, but also potential drawbacks, especially from the standpoint of performance (and sometimes robustness). This manuscript aims at initiating and fostering a critical discussion on th

In this paper, we consider the distributed reactive power sharing control problem for an autonomous inverterbased microgrid with resilience for communication faults, which may be caused by partial communication link failures or some channel manipulation attacks. Under the standard decoupling approximation for bus angle differences, the reactive power flow of each inverter can be controlled by mani

Traditionally, biogenic volatile organic compound (BVOC) emissions are often considered a unidirectional flux, from the ecosystem to the atmosphere, but recent studies clearly show the potential for bidirectional exchange. Here we aimed to investigate how warming and leaf litter addition affect the bidirectional exchange (flux) of BVOCs in a long‐term field experiment in the Subarctic. We also ass

Here, we report on large eddy simulation (LES) of supersonic flow, mixing, self-ignition, and combustion in a supersonic hydrogen jet in a crossflow configuration. The configuration has been experimentally investigated at Stanford and consists of a rectilinear channel with a ramp inlet in which a hydrogen jet discharges at a 90° angle to the high enthalpy supersonic crossflow. This configuration h

Recently diverged species often show incomplete reproductive isolation and subsequently experience hybridization and introgression. The plant genus Mimulus includes many such examples of closely related taxa that prove useful for studying incipient speciation. However, Sandstedt et al. show that in contrast to other Mimulus species, species of the M. tilingii complex are characterized by strong po

Inom byggsektorn måste byggnader vara mer energieffektiva än någonsin tidigare. Tuffare byggregler kräver allt mer exakta energibehovsberäkningar för att säkerställa byggnadens operativa prestanda. Överföringsvärmeöverföringsförluster genom byggnadens kuvert spelar en nyckelroll i byggnadens totala energiprestanda. Att underskatta dessa förluster kan leda till att energikraven inte uppfylls. För nWithin the construction sector buildings are required to be more energy efficient than ever before. Tougher building regulations require ever more accurate energy demand calculations to ensure a building’s operational performance. Transmission heat transfer losses through a building’s envelope play a key role in the overall energy performance of the building. Underestimating these losses may lead

The AMP-activated protein kinase (AMPK) is a ubiquitously expressed kinase, which is activated in response to depletion of cellularenergy levels. Once active, it functions to alter cellular metabolism in a way that leads to restoration of energy levels. Therefore,AMPK is described as the key regulator of cellular energy homeostasis. Over the past years, AMPK activation has gained increasingattenti

The externalizing spectrum, including traits and behaviors such as aggression, reduced inhibitiory control and substance abuse, is associated with altered prefrontal brain morphology. However, the degree to which different manifestations of the externalizing spectrum are associated with distinct or overlapping variations in individual brain morphology is unclear. Here, we therefore used structural

Background: Factors predicting long-term prognosis in patients with acute dyspnea may guide both acute management and follow-up. The aim of this study was to identify socioeconomic and clinical risk factors for all-cause mortality among acute dyspnea patients admitted to an Emergency Department. Methods: We included 798 patients with acute dyspnea admitted to the ED of Skåne University Hospital, M

BACKGROUND: The incidence of incisional hernia is up to 20 per cent after abdominal surgery. The management of patients with incisional hernia can be complex with an array of techniques and meshes available. Ensuring consistency in reporting outcomes across studies on incisional hernia is important and will enable appropriate interpretation, comparison and data synthesis across a range of clinical

Wetland methane (CH4) emissions ([Formula: see text]) are important in global carbon budgets and climate change assessments. Currently, [Formula: see text] projections rely on prescribed static temperature sensitivity that varies among biogeochemical models. Meta-analyses have proposed a consistent [Formula: see text] temperature dependence across spatial scales for use in models; however, site-le

Honey bees are important pollinators and are subject to numerous stressors, such as changing floral resources, parasites, and agrochemical exposure. Pesticide exposure has been linked to the decline in the global honey bee population. We have limited knowledge of the metabolic pathways and synergistic effects of xenobiotics in bees. Quercetin is one of the most abundant phytochemicals in plants an

What are inhabitants’ perceptions and uses of windows in multi-dwelling buildings? This paper reports on a field study that explores daylight, the visual connection to the outside and the role of windows in the home during the day and night. Qualitative interviews were held with 20 participants living in multi-dwelling buildings. The thematic analysis identified two main components as characterist

Multiple analogs of parathyroid hormone, all of which bind to the PTH/PTHrP receptor PTH1R, are used for patients with osteoporosis and hypoparathyroidism. Although ligands such as abaloparatide, teriparatide (hPTH 1-34 [TPTD]), and long-acting PTH (LA-PTH) show distinct biologic effects with respect to skeletal and mineral metabolism endpoints, the mechanistic basis for these clinically-important

BACKGROUND: It is unclear how the length of prehospital transport time affects outcome in paediatric trauma. This study evaluated the association of transport time from alarm to arrival at hospital with adverse outcome in paediatric trauma patients in Sweden. METHODS: This was a retrospective study based on prospectively collected data from the Swedish trauma registry between 2012 and 2019 of chil

One recurrent narrative in the discussion about managerial public sector reforms is the growth in organizational professionals as a response to new accountability regimes. New Zealand has experienced modest growth rates in the general public sector workforce. Less studied, though, is whether the composition of the public sector workforce has changed, with an increase in organizational functions su
