A locking-free quadratic nurbs-based isogeometric formulation for plates analysis

Ho Chi Minh City Open University Journal of Science - Engineering and Technology, 2012
A new Reissner-Mindlin plate formulation based on a quadratic NURBS-based isogeometric is presented. In order to avoid the transverse shear locking and to improve the accuracy of the present formulation, the quadratic NURBS-based isogeometric is ...

End‐to‐End Deep Learning Framework for Freeform Metasurfaces via Non‐Uniform Rational B‐Splines Meta‐Atoms

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
This work presents a NURBS‐enabled metasurface design framework that combines freeform meta‐atom parameterization with Transformer‐based deep learning. The unified mathematical representation expands geometric degrees of freedom while enabling efficient optical‐response prediction and inverse design.

Numerical Anisotropy and Band‐Gap Formation in Finite Element Wave Propagation: Analysis and Mitigation Using Spline‐Based Elements

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...

Parameter‐Preserving Real‐time BIM Rendering via Direct GPU Ray Tracing

Computer Animation and Virtual Worlds, Volume 37, Issue 4, July/August 2026.
Parametric BIM geometry is preserved from Revit extraction to GPU ray tracing without mesh tessellation. A two‐tier cache reuses repeated geometry during export, and an instanced OptiX representation reduces memory at render time. The method lowers export time and GPU memory while preserving exact curved surfaces.

MGGAN: Learning a Multiscale Graph‐Based GAN for Non‐Parametric 3D Single‐Shape Deformation and Variation

Computer Animation and Virtual Worlds, Volume 37, Issue 4, July/August 2026.
MGGAN learns complex, high‐dimensional patterns and geometric statistics of a single 3D mesh using a multiscale graph‐based generative adversarial network. By combining spectral and spatial graph operators in a coarse‐to‐fine framework with noise injection at each scale, the method generates smooth, visually coherent, and topology‐preserving shape ...

The Anterolateral Transpedicular Transverse Process Screw Technique: Surgical Techniques, Biomechanical study and Preliminary Outcomes

Orthopaedic Surgery, Volume 18, Issue 7, Page 1375-1397, July 2026.
This study designed a novel anterolateral screw placement technique and, based on this, developed a new anterolateral fixation method. Imaging, biomechanical, and short‐term efficacy analyses revealed that the Anterolateral Transpedicular Transverse Process Screw (ALTTS) technique achieves a high success rate for L5 vertebral fixation (pedicle width ...

Bataspis crux, a galeaspid (jawless stem gnathostome) from the Lochkovian of Yunnan with a batwing‐shaped head adapted for hydrodynamic efficiency

Palaeontology, Volume 69, Issue 4, July/August 2026.
Abstract Galeaspids are an extinct group of jawless fishes from the Silurian–Devonian of China and northern Vietnam that are key to understanding the origin of vertebrate anatomical innovations. A new eugaleaspid, Bataspis crux gen. et. sp. nov., is described based on fossil material from the Lochkovian (Early Devonian) Xishancun Formation of Qujing ...
