Replication Data for: "Tracking Phase transitions of Tactoids in Sulfated Cellulose Nanocrystals using Second Harmonic Generation Microscopy"
No full textRaw data for the manuscript, it contains seven folders and their Readme files. THe manuscript demonstrates how second-harmonic generation (SHG) microscopy can be used to visualize tactoids of Cellulose Nanocrystals (CNCs) with unprecedented detail, offering three-dimensional representations of their size, morphology, and the fusion processes. Additionally, the fully cholesteric phase of the suspension can also be imaged with SHG to identify potential defects and correlate them with the fusion process of tactoids; specifically how the tactoids fuse and merge along the chiral axi
Replication Data for: Wide-band Characterization of Multi-Layer Coding Techniques to Achieve Electromagnetic Resilient Communication Networks
No full textThe dataset assesses the efficacy of a multi-layer scheme in wired communication. We conducted performance evaluations across a broad frequency range (100MHz to 1 GHz) and a diverse Signal-to-Interference Ratio (SIR) range (-20dB to 20dB). The key performance metric analyzed is False Negative, representing cases where errors occurred during data transmission, but the detector failed to identify them.
These data stem from a comprehensive EMPro simulation. The simulation delves into the physics of a three-strip line under specific voltage conditions, while simultaneously introducing random electromagnetic interferences. There are six ports in the setup. Ports 1 and 2 correspond to the first trace, while ports 3 and 4 represent the second trace. Arc three is positioned between ports 5 and 6, serving as both the input and endpoint for the system. EMPro results enable the calculation of S parameters and the determination of voltage at the endpoint, factoring in the presence of electromagnetic waves from all directions
Replication Data for: The impact of wheat bran on vitamin A bioaccessibility in lipid-containing systems
No full textIn this study, the impact of wheat bran on vitamin A bioaccessibility was investigated for systems containing bulk oil and systems containing emulsified oil. To this end, toasted and native wheat bran were mixed with vitamin A-enriched bulk and emulsified oil. Both samples with and without bran were subjected to in vitro digestion. Before and after in vitro digestion, the vitamin A content was determined. Based on these data, the vitamin A stability, vitamin A micelle incorporation efficiency and the vitamin A bioaccessibility were determined. In addition, lipid analysis was performed after digestion to determine the degree of lipid hydrolysis
Replication Data for: Low-Frequency Magnetic Shielding Effectiveness Characterization of Planar Materials: Measurements and Numerical Simulations
No full textThis dataset supports the near-field, low-frequency (LF) shielding effectiveness (SE) characterization of planar materials over the 9 kHz to 10 MHz frequency range. It includes measurement and simulation data generated using the low-frequency Finite-Element Method (FEM), focusing on key parameters such as loops' orientation (coplanar vs. parallel), loop-to-sample distance, sample size, and mounting configuration on a shielded enclosure wall
Replication Data for: FDTD Simulation and Experimental Comparative Study of a Gasket's Shielding Effectiveness Characterization: Dipole Vs. Log-Periodic Antenna
No full textThis dataset supports a comparative analysis of the shielding effectiveness of gaskets using a tuned dipole antenna (IEEE Std. 299) and a log-periodic antenna (MIL DTL 83528G). It includes 3D full-wave simulations with the Finite-Difference-Time-Domain solver and experimental validation from 200 MHz to 1 GHz. Near-field sensors in simulations assessed shielding performance at various angles and locations, while the experimental setup focused on a 0° impinging angle. The data set shows a good correlation between simulations and experiments, indicating similar shielding effectiveness for both antennas. Despite IEEE Std. 299 recommending tuned dipole antennas, log-periodic antennas are also effective and practical
An assessment of the fourth law of Kuryłowicz: does prototypicality of meaning affect language change?
No full textThis dataset consists of the data for the paper "De Smet, Isabeau. 2023. An assessment of the fourth law of Kuryłowicz: does prototypicality of meaning affect language change? Cognitive Linguistics 34(2). 261-296.". In this paper we test the validity of the fourth law of Kuryłowicz, by looking at three morphological doublets: plurals (e.g. vogels vs. vogelen), de apocope (roe vs. roede) and sjwa apocope (aard vs. aarde). We check for each case whether forms that have a more prototypical meaning tend to change more rapidly. The data for this paper consists of 6 datasets (one for each of the three case studies on type level and one for each of the three case studies on token level). It also consits of a file with R-code for each case study. The data is extracted from historical corpora and annotated with a number of psycholinguistic predictors

Replication Data for: IMU-based Pelvic Rotation Detection: A Novel Dataset, Benchmark Classifiers, and Sensor Placement Optimization
No full textThe dataset contains pseudonymized inertial sensor recordings from 39 healthy adults who performed a structured set of activities in a laboratory environment between February and March 2024 at KU Leuven, Belgium. The activities included sitting, standing, walking, sit-to-stand-to-sit transitions, and targeted pelvic rotations in both anterior–posterior and posterior–anterior directions at varying amplitudes. Data were collected using the entire set of Xsens motion capture sensors at 60 Hz, and activity segments were annotated using synchronized video and the Xsens MVN Avatar software. The aim of the study was to evaluate the feasibility of detecting pelvic rotation and related activities with a single wearable sensor, and to provide a dataset that enables replication of the analyses and further research in activity recognition, posture monitoring, and rehabilitation
Continuous Affect Measures for Daily Life
No full textIn this study, we collected data using a newly developed continuous affect item, which allowed participants to visually depict changes in their affective experience over short time spans. A total of 117 participants took part in a one-week experience sampling study, during which they received six notifications per day on their smartphones. These notifications alternated between two types: (1) a brief prompt assessing momentary positive and negative affect, and (2) an extended questionnaire that included momentary affect ratings, continuous affect drawings, event reports, and rumination items. Additionally, participants completed a daily measurement burst, consisting of six extra momentary assessments between two regular prompts.
From the second daily prompt onward, participants were asked to draw their affective changes, both positive and negative, since the previous assessment, and to report any affective events that occurred in that interval. This approach allowed us to examine continuous affect drawings as an innovative method for capturing affective dynamics between discrete assessments. While traditional intensive longitudinal designs often leave “blind spots” between time points, this method enabled a more fine-grained reconstruction of affective fluctuations throughout the day
