(author), Harrison, Richard J. (author), van Leeuwen, Tristan (author), Barnhoorn, A. (author)Our understanding of the past behavior of the geomagnetic field arises from magnetic signals stored in geological materials, e.g., (volcanic) rocks. Bulk rock samples, however, often contain magnetic grains that differ in chemistry, size, and shape; some of them record the Earth's magnetic field well, others are unreliable. The presence of a...journal article 2021

(author)Mangrove vegetation constitutes a natural coastal defence against waves and erosion. Despite their protective role, mangrove ecosystems have experienced continuous degradation over the last decades due to human causes. At retreating mangrove coastlines, bamboo structures are built to create new habitat for mangrove colonization. Existing...journal article 2021

Genetics Contributes to Concomitant Pathology and Clinical Presentation in Dementia with Lewy Bodiesvan der Lee, S.J. (author), van Steenoven, Inger (author), van de Beek, Marleen (author), Tesi, N. (author), Jansen, Iris E. (author), van Schoor, N.M. (author), Reinders, M.J.T. (author), Huisman, Martijn (author), Scheltens, Philip (author)Background: Dementia with Lewy bodies (DLB) is a complex, progressive neurodegenerative disease with considerable phenotypic, pathological, and genetic heterogeneity. Objective: We tested if genetic variants in part explain the heterogeneity in DLB. Methods: We tested the effects of variants previously associated with DLB (near APOE, GBA, and...journal article 2021

(author), Neubert, D. S. (author), Vos, M. J.C. (author), de Winter, J.C.F. (author)Much psychological research uses pupil diameter measurements to investigate the cognitive and emotional effects of visual stimuli. A potential problem is that accommodating at a nearby point causes the pupil to constrict. This study examined to what extent accommodation is a confounder in pupillometry research. Participants solved...journal article 2021

Varotto, Silvia F. (author), Jansen, Reinier (author), Bijleveld, Frits (author), van Nes, C.N. (author)Automatic incident detection (AID) systems and variable speed limits (VSLs) can reduce crash probability and traffic congestion. Studies based on loop detector data have shown that AID systems decrease the variation in speeds between drivers. Despite the impact on driver behaviour characteristics, most mathematical models evaluating the...journal article 2021

(author)Ammonium levels in sweat can potentially be used to measure muscle fatigue and to diagnose particular metabolic myopathies. To research the potential use of ammonia in sweat as a biomarker, a new real-time monitoring system is developed. This system consists of a capsule that is placed on the skin and ventilated with dry air. A metal-oxide...journal article 2021

Jansen, S.C. (author), Mohammadi, S. (author), Bokel, R.M.J. (author)This paper describes a step-by-step approach for generating various energy concepts for neighbourhoods, based on local renewable resources. The approach is developed within the European research project ‘Smart Urban Isle’ (SUI). While much literature is focussed on comparison or optimization of predefined configurations, the SUI approach adds...journal article 2021

Varotto, Silvia F. (author), Jansen, Reinier (author), Bijleveld, Frits (author), van Nes, C.N. (author)Traffic congestion and crash rates can be reduced by introducing variable speed limits (VSLs) and automatic incident detection (AID) systems. Previous findings based on loop detector measurements have revealed that drivers reduce their speeds while approaching traffic congestion when the AID system is active. Notwithstanding these behavioural...journal article 2021

Jansen, S.J.T. (author)There are two ongoing trends that lead to changing preferences for the built environment. One concerns a demographic transition into more but smaller, and older, households. The other concerns greater possibilities to satisfy residential preferences due to rising incomes and technological advances. The current study explores the preference...journal article 2020
