Greek formulae in Coptic legal documents (7th-8th c.) : graphemic and linguistic adaptation vs. alternation Universiteit Gent

Antonia Apostolakou
The paper investigates motivations behind linguistic and paleographic variation of Greek formulaic speech in the opening, body, and closing of Coptic legal documents. The primary corpus consists of late-seventh- and eighth-century legal deeds with Greek formulaic expressions from the area of Djeme, which is well-documented and allows diachronic observations on inter- and intra-writer variation. Documents mainly from the Hermopolite nome, dating ...

Combined computational-experimental investigation of residual stresses and pre-cracking in mode I behaviour of thick adhesively bonded GFRP composite joints Vrije Universiteit Brussel

Ali Shivaie Kojouri, Jialiang Fan, Anastasios P. Vassilopoulos, Véronique Michaud, Kalliopi-Artemi Kalteremidou, Danny Van Hemelrijck, Wim Van Paepeghem
This paper presents a novel Finite Element (FE) simulation approach to examine the mode I fracture of thick adhesive joints used particularly in the trailing edge of the wind turbine blades. The approach involved FE models of the DCB specimens focusing on aspects overlooked in the existing literature. There has been limited investigation on residual stresses caused by thermal mismatch between composites and adhesives. Similarly, the impact of ...

Validation of EUHFORIA cone and spheromak coronal mass ejection models KU Leuven

Antonio Esteban Niemela, Anwesha Maharana, Stefaan Poedts
Aims. We present the validation results for arrival times and geomagnetic impact of Coronal Mass Ejections (CMEs), using the cone and spheromak CME models implemented in EUropean Heliospheric FORecasting Information Asset (EUHFORIA). Validating numerical models is crucial in ensuring their accuracy and performance with respect to real data. Methods. We compare CME plasma and magnetic field signatures, measured in situ by satellites at the L1 ...

Clinical practice in European centres treating paediatric posterior fossa tumours with pencil beam scanning proton therapy. KU Leuven

Karen Van Beek
BACKGROUND AND PURPOSE: As no guidelines for pencil beam scanning (PBS) proton therapy (PT) of paediatric posterior fossa (PF) tumours exist to date, this study investigated planning techniques across European PT centres, with special considerations for brainstem and spinal cord sparing. MATERIALS AND METHODS: A survey and a treatment planning comparison were initiated across nineteen European PBS-PT centres treating paediatric patients. The ...

Cryogenic Fracture Characterisation of High‑Grade Pipeline Steels Using the Dynamic Tensile Tear Test Equipped with a Large‑Surface Spray Cooling System KU Leuven

Reza Talemi
Background In contrast to traditional impact-based testing, the Dynamic Tensile Tear Test (DT3) has shown great potential to characterise high-grade pipeline steels as it mimics the in-field pipeline conditions. However, material characterisation using the DT3 method has only been performed at room temperature and lower-shelf characterisation has not yet been investigated. Objective This study investigates a solution to perform low-temperature ...

A Multi-Sample Comparison and Rasch Analysis of the Evaluation of Children's Listening and Processing Skills Questionnaire. KU Leuven

Sam Denys, Nicolas Verhaert, Astrid van Wieringen
OBJECTIVES: Assessing listening difficulties and associated complaints can be challenging. Often, measures of peripheral auditory functions are within normal ranges, making clinicians feel unsure about proper management strategies. The range and nature of observed or experienced difficulties might be better captured using a qualitative measure. The Evaluation of Children's Listening and Processing Skills (ECLiPS) questionnaire was designed to ...

Intravoxel incoherent motion as a surrogate marker of perfused vascular density in rat brain KU Leuven

Bram Callewaert, Willy Gsell, Elizabeth Jones, Uwe Himmelreich
Intravoxel incoherent motion (IVIM) MRI has emerged as a valuable technique for the assessment of tissue characteristics and perfusion. However, there is limited knowledge about the relationship between IVIM-derived measures and changes at the level of the vascular network. In this study, we investigated the potential use of IVIM MRI as a noninvasive tool for measuring changes in cerebral vascular density. Variations in quantitative ...

Recent trends and disparities in 24-hour movement behaviors among US youth with mental, behavioral and neurodevelopmental conditions KU Leuven

Tine Van Damme
BACKGROUND: Meeting 24-h movement behaviors (24-HMB: physical activity [PA], screen time [ST], and sleep [SL]) recommendations may be associated with positive health outcomes among youth with specific mental, behavioral, and neurodevelopmental (MBD) conditions. However, temporal trends and disparities in meeting 24-HMB guidelines in these higher-risk groups have not been investigated, hampering the development of evidence-based clinical and ...

DeltaScan for the Assessment of Acute Encephalopathy and Delirium in ICU and non-ICU Patients, a Prospective Cross-Sectional Multicenter Validation Study Vrije Universiteit Brussel KU Leuven

Fienke L Ditzel, Suzanne C A Hut, Mark van den Boogaard, Michel Boonstra, Frans S S Leijten, Evert-Jan Wils, Tim van Nesselrooij, Marjan Kromkamp, Paul J T Rood, Christian Röder, et al.

OBJECTIVES: To measure the diagnostic accuracy of DeltaScan: a portable real-time brain state monitor for identifying delirium, a manifestation of acute encephalopathy (AE) detectable by polymorphic delta activity (PDA) in single-channel electroencephalograms (EEGs).

DESIGN: Prospective cross-sectional study.

SETTING: Six Intensive Care Units (ICU's) and 17 non-ICU departments, including a psychiatric department across 10 ...

Exploring the impact of stochastic transient phases on the NO𝑥 emissions from NH3/H2 mixture rich combustion in gas turbines Vrije Universiteit Brussel

Roeland De Meulenaere, Kevin Verleysen, Alessio Pappa, Kevin Bioche, Ward De Paepe, Laurent Bricteux, Julien Blondeau

To reduce climate impact, switching to carbon-free electrofuels is an interesting option to reduce greenhouse gas emissions from electricity generation. The emission of other pollutants than CO2, such as nitrogen oxides (NOx), however, remains a concern. This research focuses on investigating the impact of transient phases, such as start-up and load change, on the NOx emissions expected from the rich combustion of mixtures of hydrogen and ...
