The paper explores the usage of minimax adaptive controllers to guarantee finite L2 -gain simultaneous stabilization of linear time-invariant (LTI) plants. It is shown that a minimax adaptive controller simultaneously stabilizes any two multiple-input multiple-output (MIMO) P-stabilizable LTI plants when no LTI controller can achieve that, and the worst attained L2 -gain bound for the transient dy
Background: ‘Collegial Midwifery Assistance’ (CMA) is a clinical practice aiming to reduce severe perineal trauma (SPT) during childbirth. This practice involves two midwives being present during the active second stage of labour rather than one, which is the case in standard care. The effectiveness of CMA was evaluated in the Oneplus trial and a 30% reduction in SPT was shown. Aim: The aim was to
This paper addresses the problem of dealing with measurable disturbances in cascade control schemes. The combination of cascade and feedforward control algorithms is analyzed. The design of a static feedforward compensators control scheme to assist the controller in the rejection of measurable disturbances is a widely accepted solution in the literature. This article proposes a new solution by imp
Research shows that today’s societal crises are rooted in a lack of connection to ourselves, others and nature. At the same time, there is an increasing body of knowledge showing that humans possess innate capacities for connection that can be strengthened through certain methods, and throughout our lifetimes. Such methods have, so far, however, been rarely applied, or adapted to the context of su
Surfactants are ubiquitous in formulated products and technologies. As one of the most important commodity chemicals, their remarkable consumption leads to the necessity of finding sustainable alternatives. Although the use of renewable sources limits the available chemical space for a “Green” production, the great variety of naturally occurring precursors, i.e., fatty acids and sugars, opens a my
We show that single crystal films of Be can be grown on Si(111) substrates, exhibiting nearly identical surface electronic bandstructure to that found on the pristine Be(0001) surface of bulk Be. Segregation of silicon atoms into the film causes strong doping of the surface states. For sufficiently thin films, the quality and uniformity are sufficient to observe well-defined quantum well states. I
α-Synuclein is an intrinsically disordered presynaptic protein associated with Parkinson's disease. The physiological role of α-Synuclein is not fully understood, but the protein is known to interact with lipid membranes. We here study how membrane charge affects the adsorption of α-Synuclein to (i) supported lipid bilayers and (ii) small unilamellar vesicles with varying amounts of anionic lipids
This article deals with chess as a popular culture phenomenon and its relations to urban space. Intermedial theory is used in analyses of a music video, a TV-serial, and a few other examples.
A superdeformed rotational band has been identified in 36Ar, linked to known low-spin states, and observed to its high-spin termination at Iπ = 16+. Cranked Nilsson-Strutinsky and spherical shell model calculations assign the band to a configuration in which four pf-shell orbitals are occupied, leading to a low-spin deformation β2 ≈ 0.45. Two major shells are active for both protons and neutrons,
Background and aims: The N-terminal propeptide of type III collagen (PRO-C3) assay measures a pro-peptide released during type III collagen synthesis, an important feature of arterial stiffening and atherogenesis. There is a clinical need for improved non-invasive, cheap and easily accessible methods for evaluating individuals at risk of cardiovascular disease (CVD). In this study, we investigate
To understand, predict and mitigate climate change, it is crucial to have long-term and standardised measurements of greenhouse gas concentrations in the atmosphere and their fluxes between atmosphere, land and oceans. The Integrated Carbon Observation System, is a distributed European Research Infrastructure which provides high-precision and highly standardised observations from more than 170 sta
