Low-proficiency students’ engagement with combined written and audio feedback in an EFL writing class

In recent years, there has been an increase in research on English as a foreign language (EFL) learners’ engagement with teachers’ feedback; however, little is known about how students engage with feedback combining written and audio feedba...

Використання технології BYOD у процесі навчання в основній школі

У статті розкривається високий потенціал використання мобільних пристроїв як одного з видів сучасних навчальних засобів під час навчання учнів у основній школі. Зокрема розглянуті переваги застосування технології BYOD, подано шляхи вирішенн...

An Investigation of Disk Thickness in M51 from Hα, Paα, and Mid-infrared Power Spectra

Power spectra (PS) of high-resolution images of M51 (NGC 5194) taken with the Hubble Space Telescope and the James Webb Space Telescope (JWST) have been examined for evidence of disk thickness in the form of a change in slope between large ...

On the Use of Transfer Entropy to Investigate the Time Horizon of Causal Influences between Signals

Understanding the details of the correlation between time series is an essential step on the route to assessing the causal relation between systems. Traditional statistical indicators, such as the Pearson correlation coefficient and the mut...

Error Analysis of a PFEM Based on the Euler Semi-Implicit Scheme for the Unsteady MHD Equations

In this article, we mainly consider a first order penalty finite element method (PFEM) for the 2D/3D unsteady incompressible magnetohydrodynamic (MHD) equations. The penalty method applies a penalty term to relax the constraint “∇·u=0”, whi...

Asteroseismology of the Nearby K Dwarf σ Draconis Using the Keck Planet Finder and TESS

Asteroseismology of dwarf stars cooler than the Sun is very challenging owing to the low amplitudes and rapid timescales of oscillations. Here we present the asteroseismic detection of solar-like oscillations at 4-minute timescales ( ${\nu ...

A Deep Learning Harmonization of Multi-Vendor MRI for Robust Intervertebral Disc Segmentation

Magnetic resonance imaging (MRI) provides enhanced soft tissue contrast and high spatial resolution. However, the relationship between intensity values among soft tissues in MRI is inconsistent, even when obtained under the same conditions ...

Exploring a Novel Material and Approach in 3D-Printed Wrist-Hand Orthoses

This article proposes the integration of two novel aspects into the production of 3D-printed customized wrist-hand orthoses. One aspect involves the material, particularly Colorfabb varioShore thermoplastic polyurethane (TPU) filament with ...

3D printing technology in the management of carpal tunnel syndrome: A case report

A 35-year-old individual with carpal tunnel syndrome presented with tingling and numbness in the left thumb, index, and middle finger. A 3D printed CTS splint was crafted to immobilize the affected wrist joint, aiding pharmacotherapy. At si...

A Real-Time Distance Measurement System for a Digital Twin Using Mixed Reality Goggles

This paper presents a new system architecture for controlling industrial devices using Mixed Reality (MR) applications and a new method based upon them for measuring the distance between real and virtual points. The research has been carrie...

Characterization of Wing Kinematics by Decoupling Joint Movement in the Pigeon

Birds have remarkable flight capabilities due to their adaptive wing morphology. However, studying live birds is time-consuming and laborious, and obtaining information about the complete wingbeat cycle is difficult. To address this issue a...

Optimizing Post-Curing Protocols for 3D-Printed Dental Models: A Long-Term Evaluation of Mechanical and Physical Properties

This study evaluated the influence of post-polymerization duration and a 14-day aging period on the mechanical and physical properties of 3D-printed standard resin models. Methods: Specimens were printed using Anycubic resin (50 µm layers) ...

Catheter pose-dependent virtual angioscopy images for endovascular aortic repair: validation with a video graphics array (VGA) camera

Previous research reported catheter pose-dependent virtual angioscopy images for endovascular aortic repair (EVAR) (phantom studies) without any validation with video images. The goal of our study focused on conducting this validation using...

A Finite Element Model to Simulate Defect Formation during Friction Stir Welding

In this study, a 3D coupled thermo-mechanical finite element model is developed to predict and analyze the defect formation during friction stir welding based on coupled Eulerian Lagrangian method. The model is validated by comparing the es...

Generalized Task‐Driven Design of Soft Robots via Reduced‐Order Finite Element Method‐Based Surrogate Modeling

Task‐driven design of soft robots requires models that are physically accurate and computationally efficient, while remaining transferable across actuator designs and task scenarios. However, existing modeling approaches typically face a fu...
