OUGS: Active View Selection via Object‐aware Uncertainty Estimation in 3DGS

Computer Graphics Forum, EarlyView.
Abstract Recent advances in 3D Gaussian Splatting (3DGS) have achieved state‐of‐the‐art results for novel view synthesis. However, efficiently capturing high‐fidelity reconstructions of specific objects within complex scenes remains a significant challenge.

Dose Assessment on the Mean Absorbed Estimates Derived from the Simple Approach Method Applying Marinelli-Quimby’s Formula for Ambient Risk Organs to Thyroid Uptake in the Administered 131I Radiopharmaceutical of Graves’ Disease Using PHITS and ICRP Reference Computational Voxel Phantom

Dose Assessment on the Mean Absorbed Estimates Derived from the Simple Approach Method Applying Marinelli-Quimby’s Formula for Ambient Risk Organs to Thyroid Uptake in the Administered 131I Radiopharmaceutical of Graves’ Disease Using PHITS and ICRP Reference Computational Voxel Phantom
This study aimed to report a simple approach dosimetric tool for ambient risk organs/tissues (targets) to thyroid uptake (source) for 131I radiopharmaceutical of Graves’ disease. The dosimetric tool introduced in this study is based on the mean absorbed dose estimates and calculations by the Monte-Carlo code in radiation transport of particle heavy ion

Real‐Time Rendering of Dynamic Line Sets using Voxel Ray Tracing

Computer Graphics Forum, EarlyView.
Abstract Real‐time rendering of dynamic line sets is relevant in many visualization tasks, including unsteady flow visualization and interactive white matter reconstruction from Magnetic Resonance Imaging. High‐quality global illumination and transparency are important for conveying the spatial structure of dense line sets, yet remain difficult to ...

NAADF: Globally Illuminated Voxel Worlds Accelerated with Nested Axis‐Aligned Distance Fields

Computer Graphics Forum, EarlyView.
Abstract Achieving realistic rendering of 3D scenes in real time using path tracing is challenging due to the high sample count required, with ray tracing as the bottleneck. Focusing on voxels as a geometry representation offers significant opportunities for optimizations, especially for tracing the rays, but also for computing the samples.

A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, EarlyView.
This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.

Virtual reality and haptic simulation in modern microsurgical endodontics: Case report and proof of concept

International Endodontic Journal, EarlyView.
Abstract Aim To highlight the development and application of a novel virtual reality (VR) haptic simulation program in endodontic microsurgery (EMS) to prepare for a clinical case performed by a resident student. Summary Modern EMS requires adequate training and a learning curve for mastering surgical techniques and refining individual skills.
