The importance of recurring public transport delays for accessibility and mode choice

This paper looks at the relationship between recurring public transport delays, accessibility to jobs, and travel behaviour in the region of Scania, Sweden. The difference between potential (scheduled) accessibility, observed (actual) accessibility, and behaviour is an important part of this research. This paper contributes to the growing body of literature that uses GTFS data (for both scheduled

Quantitative methods for train delay propagation research

Due to the increase in railway traffic, trains increasingly need to adhere to their scheduled path to avoid extensive propagation of delays. This paper presents the findings of a systematic literature review covering articles related to the delay propagation problems of trains. By searching both the Scopus and Web of Science databases, the content of 156 relevant papers was screened and analyzed.

Identifying biomarkers deciphering sepsis from trauma-induced sterile inflammation and trauma-induced sepsis

OBJECTIVE: The purpose of this study was to identify a panel of biomarkers for distinguishing early stage sepsis patients from non-infected trauma patients.BACKGROUND: Accurate differentiation between trauma-induced sterile inflammation and real infective sepsis poses a complex life-threatening medical challenge because of their common symptoms albeit diverging clinical implications, namely differ

Robust Simultaneous Stabilization Via Minimax Adaptive Control

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

Women's experiences of being assisted by two midwives during the active second stage of labour : Secondary outcomes from the Oneplus trial

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

Double feedforward compensation for cascade control schemes

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

Revolutionising sustainability leadership and education : addressing the human dimension to support flourishing, culture and system transformation

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

The underlying order : Isomerism as a blueprint to control the behavior of sugar-based (bio)surfactants

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

Electronic structure of thin epitaxial Be films on Si(111)

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

The density of anionic lipids modulates the adsorption of α-Synuclein onto lipid membranes

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

Superdeformation in the N = z Nucleus 36Ar : Experimental, deformed mean field, and spherical shell model descriptions

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,
