Surrogate indicators are meant to be alternatives or complements of safety analyses based on accident records. These indicators are used to study critical traffic events that occur more frequently, making such incidents easier to analyse. This article provides an overview of existing surrogate indicators and specifically focuses on their merit for the analyses of vulnerable road users and the exte

The cause of the Triassic-Jurassic (Tr-J) boundary biotic crisis, one of the ‘Big Five’ mass extinctions of the Phanerozoic, remains controversial. In this study, we analyzed multiple sulfur-isotope compositions (δ33S, δ34S and δ36S) of pyrite and Spy/TOC ratios in two Tr-J successions (Mariental, Mingolsheim) from the European Epicontinental Seaway (EES) in order to better document ocean-redox va

The swelling behavior of a hydrophobic poly(2diisopropylamino)ethyl methacrylate (PDPA) brush immersed in aqueous solutions of single and mixed salts has been investigated using ellipsometry and numerical self-consistent field (nSCF) theory. As a function of solution ionic strength, the osmotic and salted brush regimes of weak polyelectrolyte brushes as well as substantial specific anion effects i

Abstract in Spanish:El estudio de la relación entre la cultura material y el lenguaje tiene una larga tradición, desde los avances en el campo de la evolución de la cultura hasta los hallazgos de las ciencias cognitivas. Las recientes conclusiones de estos estudios se inclinan por la diversidad lingüística y la lingüística evolutiva desestimando el rol de los universales. Este artículo explora el The study of the relationship between material culture and language has a long tradition, from the studies of cultural evolution to the findings of the cognitive sciences. The recent conclusions of these studies in relation to the universals of language tend towards linguistic diversity and evolutionary linguistics, neglecting the role of universals. This article explores the role of artifacts in

The heavy-duty industry typically uses a high cetane fuel to power their vehicles, currently typically fossil diesel. Switching to renewable fuels such as methanol requires a major changeover in engine technology. Due to the high octane number of methanol, the diesel engines will have to be replaced by more suitable spark-ignited engines. An accurate knock control system will then be needed to acc

Welfare capitalism has developed in the context of rapidly expanding, fossil fuel-driven industrial economies. Faced with the urgent need for systematic changes of economic systems so that they stay within planetary limits, decoupling welfare from economic growth is an important task. This chapter introduces the concept of sustainable welfare, referring to welfare systems that prioritise the satis

Aeolian transport rates decreases during wet conditions as the threshold shear velocity for initiation of transport increases over moist sand. This study investigates the influence of surface moisture on meso-scale aeolian transport simulations. Yearly transport rates towards the dunes are simulated with ten different threshold-based models to account for moisture effects. The ten models show larg

OBJECTIVE: Fine-needle aspiration cytology (FNAC) from bone lesions has been proven to be a useful diagnostic tool but lacks standardisation. The aim of the study was to evaluate the diagnostic utility of FNAC as a basis to propose and test a reporting system for bone reporting cytopathology.METHODS: This retrospective study is based on patients with bone lesions, that were approached by cytology

An orientation of a graph G is a digraph D obtained from G by replacing each edge by exactly one of the two possible arcs with the same endvertices. For each v∈V(G), the indegree of v in D, denoted by dD-(v), is the number of arcs with head v in D. An orientation D of G is proper if dD-(u)≠dD-(v), for all uv∈E(G). The proper orientation number of a graph G, denoted by χ→(G), is the minimum of the

Historical commons represent self-governed governance regimes that regulate the use and management of natural and man-made shared resources. Despite growing scientific interests, analyses of commons evolution and temporal dynamics are rare and drivers of change (birth, adaptation, dissolution) remain obscure. We apply an interdisciplinary approach and address these issues from an eco-evolutionary

This paper applies the peridynamic continuum mechanics theory on a new type of material known as harmonic-structured materials. Using the Peridigm software, rapid uniaxial elongation is simulated on a peridynamic model of a thin bimodal harmonic-structured metal sheet. Mechanical wave initiation, propagation, and reflection, as well as fracture initiation and propagation are successfully simulated

Bradshaw et al. (2021) make a call to action in light of three major crises—biodiversity loss, the sixth mass extinction, and climate disruption. We have no contention with Bradshaw et al.’s diagnosis of the severity of the crises. Yet, their call for scientists to “tell it like it is,” their appeal to political “leaders,” and the great attention they afford to human population growth as a main dri

A well-known property of sexual selection combined with a cross-sex genetic correlation (rmf) is that it can facilitate a peak shift on the adaptive landscape. How do these diversifying effects of sexual selection + rmf balance with the constraints imposed by such sexual antagonism, to affect the macroevolution of sexual dimorphism? Here, I extend existing quantitative genetic models of evolution

Objective: War veterans are at high risk of developing posttraumatic stress disorder (PTSD), and the development of brief self-report instruments that enable screening for PTSD in this population is crucial. The PTSD Checklist-Military Version (PCL-M) is widely used for this purpose. This study sought to explore the diagnostic utility of the Portuguese version of the PCL-M. Methods: The participan

The Tobii Pro TX300 is a popular eye tracker in developmental eye-tracking research, yet it is no longer manufactured. If a TX300 breaks down, it may have to be replaced. The data quality of the replacement eye tracker may differ from that of the TX300, which may affect the experimental outcome measures. This is problematic for longitudinal and multi-site studies, and for researchers replacing eye

In recent years the list of disorders affecting amino acid synthesis has grown rapidly. Not only the number of defects has increased, but also the associated clinical phenotypes have expanded spectacular, the latter mainly due to the advances of next-generation sequencing diagnostics. An important reason for the contribution of NGS in the diagnosis of amino acid synthesis disorders is the fact tha

Do personality traits in highly intelligent individuals relate to their work engagement? Seemingly little is known about the relationship between personality and work engagement for gifted individuals. In what may be the first study to do so, a Swedish Mensa sample (n = 353) was explored with a two-part aim: to assess psychometric personality properties and to investigate the relationship between
