Apparent nonlinear damping triggered by quantum fluctuations

Gely, M.F. (author), Sanz Mora, A. (author), Yanai, S. (author), van der Spek, Rik (author), Bothner, D. (author), Steele, G.A. (author)

Nonlinear damping, the change in damping rate with the amplitude of oscillations plays an important role in many electrical, mechanical and even biological oscillators. In novel technologies such as carbon nanotubes, graphene membranes or superconducting resonators, the origin of nonlinear damping is sometimes unclear. This presents a problem...

Understanding meso-scale processes at a mixed-energy tidal inlet: Ameland Inlet, the Netherlands – Implications for coastal maintenance

Elias, Edwin P.L. (author), Pearson, S.G. (author), van der Spek, A.J.F. (author), Pluis, Stefan (author)

For successful and sustainable management of barrier islands, a thorough understanding of the ebb-tidal delta dynamics and interactions with the adjacent shorelines are of the utmost importance. Such understanding requires detailed observations and interpretations of the morphodynamics of smaller-scale features such as the individual channels...

A novel approach to mapping ebb-tidal delta morphodynamics and stratigraphy

Pearson, S.G. (author), Elias, Edwin (author), van Prooijen, Bram (author), van der Vegt, H. (author), van der Spek, A.J.F. (author), Wang, Zhengbing (author)

Ebb tidal deltas (ETDs) are highly dynamic features of sandy coastal systems, and coastal management concerns (e.g., nourishment and navigation) present a pressing need to better describe and quantify their evolution. Here we propose two techniques for leveraging the availability of high-resolution bathymetric surveys to generate new insights...

Modeling the Morphodynamic Response of Estuarine Intertidal Shoals to Sea-Level Rise

Elmilady, H.M.S.M.A. (author), van der Wegen, M. (author), Roelvink, D. (author), van der Spek, A. (author)

Intertidal shoals are key features of estuarine environments worldwide. Climate change poses questions regarding the sustainability of intertidal areas under sea-level rise (SLR). Our work investigates the SLR impact on the long-term morphological evolution of unvegetated intertidal sandy shoals in a constrained channel-shoal system....

Development of intertidal flats in the Dutch Wadden Sea in response to a rising sea level: Spatial differentiation and sensitivity to the rate of sea level rise

Huismans, Y. (author), van der Spek, A.J.F. (author), Lodder, Q.J. (author), Zijlstra, Robert (author), Elias, Edwin (author), Wang, Zhengbing (author)

The Wadden Sea is a unique intertidal wetland area, forming an important hub for migratory water birds. A feared effect of accelerated sea-level rise (SLR) is the gradual loss or even disappearance of the ecologically valuable intertidal flats. To date, the effect of SLR on the time-evolution of the intertidal areas in the Dutch Wadden Sea...

The impact of interventions in the built environment on physical activity levels: a systematic umbrella review

Physical activity is good for people’s health. The relationship between the built environment and physical activity has been well documented. However, evidence is both scarce and scattered on specific urban interventions, i.e., intentional redesigns of the built environment that promote physical activity accompanied by pre- and post-effect...

Walkability analyses of Delft city centre by Go-Along walks and testing of different design scenarios for a more walkable environment

Erturan Topgül, G.A. (author), van der Spek, S.C. (author)

This study seeks answers to the research question ‘How can walkability of urban spaces be analysed with a multidimensional approach by using mobile methods?’ The research consists of a literature review, a field study in the city centre of Delft conducted as Go-Along walks, which provide better insight in capturing the experience of walking...

Travellers’ preferences towards existing and emerging means of first/last mile transport: a case study for the Almere centrum railway station in the Netherlands

Stam, Bas (author), van Oort, N. (author), van Strijp-Harms, Hilke J. (author), van der Spek, S.C. (author), Hoogendoorn, S.P. (author)

First/last mile transport is essential for transit but is often found to be the weakest link in a trip. Moreover, as a result of multiple developments (e.g. demographic shifts, urbanization, climate change, technology advancement) first/last mile transport will likely change rapidly. The literature review of this study shows six different...

Morphodynamic Evolution of a Fringing Sandy Shoal: From Tidal Levees to Sea Level Rise

Elmilady, H.M.S.M.A. (author), Van Der Wegen, M. (author), Roelvink, D. (author), van der Spek, A. (author)

Intertidal shoals are vital components of estuaries. Tides, waves, and sediment supply shape the profile of estuarine shoals. Ensuring their sustainability requires an understanding of how such systems will react to sea level rise (SLR). In contrast to mudflats, sandy shoals have drawn limited attention in research. Inspired by a channel...

Metabolomics examines the small molecules involved in cellular metabolism. Approximately 50% of total phenotypic differences in metabolite levels is due to genetic variance, but heritability estimates differ across metabolite classes. We perform a review of all genome-wide association and (exome-) sequencing studies published between November...

Future Response of the Wadden Sea Tidal Basins to Relative Sea-Level rise—An Aggregated Modelling Approach

Lodder, Q.J. (author), Wang, Zhengbing (author), Elias, Edwin P.L. (author), van der Spek, A.J.F. (author), de Looff, Harry (author), Townend, Ian (author)

Climate change, and especially the associated acceleration of sea-level rise, forms a serious threat to the Wadden Sea. The Wadden Sea contains the world’s largest coherent intertidal flat area and it is known that these flats can drown when the rate of sea-level rise exceeds a critical limit. As a result, the intertidal flats would then be...

Small island developing states are among the most vulnerable areas to the impact of natural hazards and climate change. Flooding due to storm surges and extreme waves, coastal erosion, and salinization of freshwater lenses are already a serious threat and could lead to irreversible consequences in the coming decades. Reef flat mining is one...

Ameland inlet is centrally located in the chain of West Frisian Islands (the Netherlands). A globally unique dataset of detailed bathymetric charts starting in the early 19th century, and high-resolution digital data since 1986 allows for detailed investigations of the ebb-tidal delta morphodynamics and sediment bypassing over a wide range of...

Predicting longer-term mortality risk requires collection of clinical data, which is often cumbersome. Therefore, we use a well-standardized metabolomics platform to identify metabolic predictors of long-term mortality in the circulation of 44,168 individuals (age at baseline 18–109), of whom 5512 died during follow-up. We apply a stepwise ...
