(2021-02-18)
Article
Open AccessThe accessibility and availability of a variety of online gambling for adolescents is a public concern. In the current literature, it remains unclear in which activities the greatest prevalence occurs. Moreover, it is ... -
Social network size, loneliness, physical functioning and depressive symptoms among older adults: examining reciprocal associations in four waves of the Longitudinal Aging Study Amsterdam (LASA)
(2021-04-28)
Article
Open AccessIntroduction Previous research indicates that social isolation, loneliness, physical dysfunction and depressive symptoms are interrelated factors, little is known about the potential pathways among them. The aim of the ... -
Adaptive Volt-Var Control Algorithm to Grid Strength and PV Inverter Characteristics
(2021-04-16)
Article
Open AccessThe high-penetration of Distributed Energy Resources (DER) in low voltage distribution grids, mainly photovoltaics (PV), might lead to overvoltage in the point of common coupling, thus, limiting the entrance of renewable ... -
Policy challenges for the development of energy flexibility services
(2020-02)
Article
Open AccessEuropean energy policies call for an increased share of renewable energy sources and a more active role of the energy consumer. This is facilitated by, amongst others, buildings becoming energy flexible hubs, supporting ... -
The Zipf–Poisson-stopped-sum distribution with an application for modeling the degree sequence of social networks
(2020-03-01)
Article
Restricted access - publisher's policyUnder the Zipf Distribution, the frequency of a value is a power function of its size. Thus, when plotting frequencies versus size in log–log scale of data following that distribution, one obtains a straight line. The Zipf ... -
A nonparametric test for the association between longitudinal covariates and censored survival data
(Oxford University Press, 2020-10-01)
Article
Restricted access - publisher's policyMany biomedical studies focus on the association between a longitudinal measurement and a time-to-event outcome while quantifying this association by means of a longitudinal-survival joint model. In this article we propose ... -

(2021-01-01)
Article
Restricted access - publisher's policyn an infectious disease cohort study, individuals who have been infected with apathogenare often recruited for follow up. The period between infection and the onset of symptomatic disease, referred to as the incubation ... -

A new interior-point approach for large separable convex quadratic two-stage stochastic problems
(2020-11-03)
Article
Open AccessTwo-stage stochastic models give rise to very large optimization problems. Several approaches havebeen devised for efficiently solving them, including interior-point methods (IPMs). However, usingIPMs, the linking columns ... -
Prefrontal cortex neuromodulation enhances frontal asymmetry and reduces caloric intake in patients with morbid obesity
(2020-04)
Article
Open AccessObjective The objective of this study was to test the feasibility of a combined intervention involving transcranial direct current stimulation (tDCS) on the dorsolateral prefrontal cortex (dlPFC) and cognitive training ... -
A surrogate-based cooperative optimization framework for computationally expensive black-box problems
(2020-07-02)
Article
Open AccessMost parallel surrogate-based optimization algorithms focus only on the mechanisms for generating multiple updating points in each cycle, and rather less attention has been paid to producing them through the cooperation ...
