(author)Electrical properties tomography (EPT) is an imaging method that uses a magnetic resonance (MR) system to non-invasively determine the spatial distribution of the conductivity and permittivity of the imaged object. This manuscript starts by providing clear definitions about the data required for, and acquired in, EPT, followed by comprehensively...journal article 2021

van Schelven, R.M. (author), Fiorellini Bernardis, A. (author), Sberna, P.M. (author), Neto, A. (author)Semiconductor (SC)-based bulk absorbers operating in the (sub-) THz range are discussed. The conductivities of the bulk media are described by the Drude model for electron gas where the electron density is controlled. The Drude model predicts the existence of two frequencies of interest: one associated with the scattering time of the electrons...journal article 2021

Wang, Y. (author), de Hoop, S. (author), Voskov, D.V. (author), Bruhn, D.F. (author), Bertotti, G. (author)Multiphase mass and heat transfer are ubiquitous in the subsurface within manifold applications. The presence of fractures over several scales and complex geometry magnifies the uncertainty of the heat transfer phenomena, which will significantly impact, or even dominate, the dynamic transport process. Capturing the details of fluid and heat...journal article 2021

Tabakovic, A. (author), Mohan, Joseph (author), Karač, Aleksandar (author)This paper explores the potential use of conductive alginate capsules encapsulating a bitumen rejuvenator as a new extrinsic self-healing asphalt method. The capsules combine two existing self-healing asphalt technologies: (1) rejuvenator encapsulation and (2) induction heating to create a self-healing system that will provide rapid and...journal article 2021

Kraft, Marvin A. (author), Gronych, Lara M. (author), Famprikis, T. (author), Zeier, Wolfgang G. (author)Exploration of sulfidic sodium solid electrolytes and their design contributes to advances in solid-state sodium batteries. Such a design is guided by a better understanding of fast sodium transport, for instance, in the herein studied Na11Sn2PS12-type materials. By using Rietveld refinements against synchrotron X-ray diffraction and...journal article 2021

FE2 multi-scale framework for the two-equation model of transient heat conduction in two-phase mediaZhuo, M. (author)In the study of transient heat conduction in heterogeneous two-phase media, the local thermal non-equilibrium condition calls for the use of a two-equation model to appropriately describe different temperatures in the two phases. We propose for the two-equation model an FE<sup>2</sup> multi-scale framework that is capable of addressing...journal article 2021

Sun, M. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Impaired electrical conduction has been shown to play an important role in the development of heart rhythm disorders. Being able to determine the conductivity is important to localize the arrhythmogenic substrate that causes abnormalities in atrial tissue. In this work, we present an algorithm to estimate the conductivity from epicardial...journal article 2021

van der Cruijsen, J. (author), Piastra, Maria Carla (author), Selles, R.W. (author), Oostendorp, Thom F. (author)The inconsistent response to transcranial electric stimulation in the stroke population is attributed to, among other factors, unknown effects of stroke lesion conductivity on stimulation strength at the targeted brain areas. Volume conduction models are promising tools to determine optimal stimulation settings. However, stroke lesion...journal article 2021

Floreani, S. (author), Redig, F.H.J. (author), Sau, Federico (author)In this paper, we introduce a random environment for the exclusion process in Z<sup>d</sup> obtained by assigning a maximal occupancy to each site. This maximal occupancy is allowed to randomly vary among sites, and partial exclusion occurs. Under the assumption of ergodicity under translation and uniform ellipticity of the environment, we...journal article 2021

(author), Oostendorp, Thom (author)Objective. Large structural brain changes, such as chronic stroke lesions, alter the current pathways throughout the patients' head and therefore have to be taken into account when performing transcranial direct current stimulation simulations. Approach. We implement, test and distribute the first MATLAB pipeline that automatically generates...journal article 2021

Rong, Jian (author), Zhu, Jia-Ning (author), Xiao, Wenlong (author), Zhao, Xinqing (author), Ma, Chaoli (author)Thermal conductivity is a key parameter for high performance material needed for electronic devices. While most commercially used Mg foundry alloys exhibit low thermal conductivities. In this work, we developed an Mg–3RE–0.5Zn alloy that is suitable for high pressure die cast (HPDC) ultrathin wall cellphone components. The thermal...journal article 2021

(author)Wide-band-gap perovskites such as methylammonium lead bromide (MAPB) are promising materials for tandem solar cells because of their potentially high open-circuit voltage, which is yet still far below the maximum limit. The relatively short charge-carrier lifetimes deduced from time-resolved photoluminescence (TRPL) measurements seem in...journal article 2021

Rietdijk, Wim (author), Renes, Sander (author)Background: We examine the incidence of medical tribunal decisions and disciplinary actions (DAs) against healthcare professionals (HCPs). In addition, we studied whether an intimate relationship between an HCP and patient as part of the medical tribunal decision is associated with an increased likelihood of disciplinary actions. Methods: We...journal article 2021
