Lai, Marco (author), van der Stel, Stefan D. (author), Groen, Harald C. (author), van Gastel, Mark (author), Kuhlmann, Koert F.D. (author), Ruers, Theo J.M. (author), Hendriks, B.H.W. (author)Surgical excision is the golden standard for treatment of intestinal tumors. In this surgical procedure, inadequate perfusion of the anastomosis can lead to postoperative complications, such as anastomotic leakages. Imaging photoplethysmography (iPPG) can potentially provide objective and real-time feedback of the perfusion status of tissues....journal article 2022

(author)The amount of suspended fines in the southern North Sea strongly depends on their exchange with the sandy seabed. This exchange is governed by resuspension of fines during storms, followed by burial in the week thereafter. Despite its importance for fine sediment dynamics, the burial of fines into a sandy seabed is currently not well...journal article 2022

(author), Bas, Michael (author), Goossens, R.H.M. (author)While there has been increasing interest in the use of gamification in mental health care, there is a lack of design knowledge on how elements from games could be integrated into existing therapeutic treatment activities in a manner that is balanced and effective. To help address this issue, we propose a design process framework to support...journal article 2021

Albaba, Adnan (author), Simões-Capela, Neide (author), Wang, Yuyang (author), Hendriks, R.C. (author), De Raedt, Walter (author), Van Hoof, Chris (author)Background and objective: Long-term electrocardiogram monitoring comes at the expense of signal quality. During unconstrained movements, the electrocardiogram is often corrupted by motion artefacts, which can lead to inaccurate physiological information. In this situation, automated quality assessment methods are useful to increase the...journal article 2021

(author), Kanstad, Terje (author), Markeset, Gro (author)Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of reinforced concrete (RC) structures, showing the structural implications/consequences of ASR, has got little attention in the...journal article 2021

Engen, Morten (author), Hendriks, M.A.N. (author), Monti, Giorgio (author), Allaix, Diego L. (author)When non-linear finite element analyses are used in design of new or assessment of existing concrete structures, one should account for the modelling uncertainty before conclusions are drawn based on the results. The present article describes the basis for how this topic is treated in the draft of fib Model Code 2020. There are two components...journal article 2021

Abdi, Bahareh (author), van Schie, Mathijs S. (author), de Groot, N.M.S. (author), Hendriks, R.C. (author)Background: Atrial electrograms recorded from the epicardium provide an important tool for studying the initiation, perpetuation, and treatment of AF. However, the properties of these electrograms depend largely on the properties of the electrode arrays that are used for recording these signals. Method: In this study, we use the electrode's...journal article 2021

(author)Background: Although the incidence of positive resection margins in breast-conserving surgery has decreased, both incomplete resection and unnecessary large resections still occur. This is especially the case in the surgical treatment of ductal carcinoma in situ (DCIS). Diffuse reflectance spectroscopy (DRS), an optical technology based on...journal article 2021

Çalış, M. (author), Heusdens, R. (author), Hendriks, R.C. (author), van de Par, Steven (author)The processing of low-frequency interaural time differences is found to be problematic among hearing-impaired people. The current generation of beamformers does not consider this deficiency. In an attempt to tackle this issue, we propose to replace the inaudible interaural time differences in the low-frequency region with the interaural level...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.
