(author), Spijkers, Klaartje (author), Coppus, Sjors F.P.J. (author), Jansen, F.W. (author)Background. During the COVID-19 pandemic the question arises if laparoscopy, as an aerosol forming procedure, poses a potential risk for viral transmission of SARS-CoV-2 to healthcare workers. Methods. A literature search was conducted using PubMed, Embase and MEDLINE. Articles reporting information regarding COVID-19 or other relevant...review 2021

(author), Appel-Meulenbroek, Rianne (author), Hoekstra, Bartele (author), Jongens-Vander Schaaf, Pity (author)Due to the COVID-19 crisis, Dutch employees were told to work from home as much as possible. Homeworking can have benefits both for employees and employers, as some experience a productivity increase and a better work-life balance. However, it is also harder for employers to measure and monitor employees’ performance and for the employee it can...conference paper 2021

van Manen, T. (author), Janbaz, S. (author), Jansen, K.M.B. (author), Zadpoor, A.A. (author)Shape-shifting materials are a powerful tool for the fabrication of reconfigurable materials. Upon activation, not only a change in their shape but also a large shift in their material properties can be realized. As compared with the 4D printing of 2D-to-3D shape-shifting materials, the 4D printing of reconfigurable (i.e., 3D-to-3D shape...journal article 2021

Teunissen, L.P.J. (author), Plaude, L. (author), Jansen, K.M.B. (author)Prolonged exposure to solar radiation can cause considerable heat stress. The application of reflective materials in garments or sunscreens is generally considered as an appropriate protective strategy. In this study, we aimed to compare a range of reflective and control fabrics on their ability to reduce the thermal impact of solar radiation....journal article 2021

Simão, T. D. (author), Jansen, Nils (author), Spaan, M.T.J. (author)Deploying reinforcement learning (RL) involves major concerns around safety. Engineering a reward signal that allows the agent to maximize its performance while remaining safe is not trivial. Safe RL studies how to mitigate such problems. For instance, we can decouple safety from reward using constrained Markov decision processes (CMDPs), where...conference paper 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

Castro, Saullo G.P. (author), Jansen, E. L. (author)Koiter's asymptotic method enables the calculation and deep understanding of the initial post-buckling behaviour of thin-walled structures. For the single-mode asymptotic analysis, Budiansky (1974) presented a clear and general formulation for Koiter's method, based on the expansion of the total potential energy function. The formulation from...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
