A novel geometry image to accurately represent a surface by preserving mesh topology
Geometry images parameterise a mesh with a square domain and store the information in a single chart. A one-to-one correspondence between the 2D plane and the 3D model is convenient for processing 3D models.

A scalable method for direct laser patterning of 2D films on transparent substrates like polycarbonate and glass is presented. This technique eliminates the need for photolithography and solvents, enabling the fabrication of functional devices like strain gauges, supercapacitors, and photodetector arrays.

Learning Delaunay Surface Elements for Mesh Reconstruction [PDF]
We present a method for reconstructing triangle meshes from point clouds. Existing learning-based methods for mesh reconstruction mostly generate triangles individually, making it hard to create manifold meshes. We leverage the properties of 2D Delaunay triangulations to construct a mesh from manifold surface elements.

GPGPU-Parallel Re-indexing of Triangle Meshes with Duplicate-Vertex and Unused-Vertex Removal [PDF]
We describe a simple yet highly parallel method for re-indexing "indexed" data sets like triangle meshes or unstructured-mesh data sets -- which is useful for operations such as removing duplicate or un-used vertices, merging different meshes, etc.

A New Approach to Automatic Generation of all Quadrilateral Mesh for Finite Element Analysis [PDF]
This paper presents a new mesh generation method for a convex polygonal domain. We first decompose the convex polygon into simple sub regions in the shape of triangles.

A Hybrid Approach for Optimizing Planar Triangular Meshes
Modified Direct Method (MDM) is an iterative scheme based on Jacobi iterations for smoothing planar meshes [4]. The basic idea behind MDM is to make any triangular element be as close to an equilateral triangle as possible.

Double Helical Plasmonic Antennas
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Fast extraction of adaptive multiresolution meshes with guaranteed properties from volumetric data [PDF]
We present a new algorithm for extracting adaptive multiresolution triangle meshes from volume datasets. The algorithm guarantees that the topological genus of the generated mesh is the same as the genus of the surface embedded in the volume dataset at ...

Hernia of the Jean Louis Petit triangle in the emergency department: a rare image
Lumbar hernias are rare lesions. They are exceptionally observed and reported. They are in most of the cases secondary to trauma or previous surgery but primary lumbar hernias are rare.

Lipid Nanoparticle‐Mediated CRISPR‐Cas13a Delivery for the Control of Bacterial Infection
New formulations of lipid nanoparticles (LNPs) that can deliver nucleic acids to Gram‐negative bacteria are proposed to combat bacterial infection. The delivery of nucleic acids by LNPs is aided by LNP‐helpers which weaken the bacterial outer membrane. LNPs encapsulating the Cas13a/gRNA expression vector achieve an antibacterial effect in both in vivo ...
