Repairing triangle meshes built from scanned point cloud [PDF]

, 2007
The Reverse Engineering process consists of a succession of operations that aim at creating a digital representation of a physical model. The reconstructed geometric model is often a triangle mesh built from a point cloud acquired with a scanner ...

Stabilization of Miscible Aqueous Phases via Diffusion‐Controlled Multifunctional Nanoparticle‐Ligand Complexation

Advanced Functional Materials, EarlyView.
This study presents a versatile approach to harnessing miscible aqueous domains, enabling liquid‐in‐liquid compartmentalization using a barrier formed in situ rather than bulk immiscibility. The barrier forms upon the complexation of multifunctional nanoparticles and ligands at the contact boundary of aqueous phases.

Exact Geosedics and Shortest Paths on Polyhedral Surface [PDF]

, 2007
We present two algorithms for computing distances along a non-convex polyhedral surface. The first algorithm computes exact minimal-geodesic distances and the second algorithm combines these distances to compute exact shortest-path distances along the ...

A Nystr\"om-based finite element method on polygonal elements

, 2017
We consider families of finite elements on polygonal meshes, that are defined implicitly on each mesh cell as solutions of local Poisson problems with polynomial data.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

A Viscous Boundary Layer Mesh Adaptation Method and Its Application in High-Angle-of-Attack Separated Flows

Applied Sciences
Adjoint-based mesh adaptation method serves as an effective approach to improve the predictive accuracy of aerodynamic characteristics. However, viscous boundary layer grids often encounter issues such as hanging nodes, negative volumes, and directional ...

A curvature theory for discrete surfaces based on mesh parallelity

, 2009
We consider a general theory of curvatures of discrete surfaces equipped with edgewise parallel Gauss images, and where mean and Gaussian curvatures of faces are derived from the faces' areas and mixed areas.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

Steric Hindrance and Secondary Interactions Govern Reconfiguration Between Two Complex CuI Coordination Cages

Angewandte Chemie, EarlyView.
Fine‐tuning steric and C─H···π contacts directs assembly of two CuI cages. An identical naphthylene‐based subcomponent forms a [CuI12L6]12+ pseudo‐hexagonal prism stabilized by 29–32 C─H···π contacts and 12 arene stacking pairs with 6‐methyl‐2‐formylpyridine, whereas the 3‐methyl analog imparts steric clashes, yielding a [CuI8L4]8+ open prism ...
