Biomechanical comparison using finite element analysis of different screw configurations in the fixation of femoral neck fractures [PDF]
Mechanical Sciences, 2015 In this research, biomechanical behaviors of five different configurations of screws used for stabilization of femoral neck fracture under axial loading have been examined, and which configuration is best has been investigated. A point cloud was obtained

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

An Effective Method for Slicing Triangle Meshes Using a Freeform Curve
MathematicsSlicing 3D polygonal meshes is a fundamental operation in various applications such as virtual surgery, garment simulation, and game development. Existing methods primarily slice meshes using either a single line or a set of line segments approximating a

penMesh—Monte Carlo Radiation Transport Simulation in a Triangle Mesh Geometry
IEEE Transactions on Medical Imaging, 2009 We have developed a general-purpose Monte Carlo simulation code, called penMesh, that combines the accuracy of the radiation transport physics subroutines from PENELOPE and the flexibility of a geometry based on triangle meshes.

Segmenting reliefs on triangle meshes [PDF]
Proceedings of the 2006 ACM symposium on Solid and physical modeling, 2006 Sculptural reliefs are widely used in various industries for purposes such as applying brands to packaging and decorating porcelain. In order to easily apply reliefs to CAD models, it is often desirable to reverse-engineer previously designed and manufactured reliefs. 3D scanners can generate triangle meshes from objects with reliefs; however, previous

Single-Strip Triangulation of Manifolds with Arbitrary Topology
, 2004 Triangle strips have been widely used for efficient rendering. It is NP-complete to test whether a given triangulated model can be represented as a single triangle strip, so many heuristics have been proposed to partition models into few long strips.

Morphing of Triangular Meshes in Shape Space [PDF]
, 2008 We present a novel approach to morph between two isometric poses of the same non-rigid object given as triangular meshes. We model the morphs as linear interpolations in a suitable shape space $\mathcal{S}$.

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Piecewise Surface Construction Method Based on Feature Detection [PDF]
Jisuanji gongcheng, 2017 Current mainstream methods for mesh piecewise reconstruction cannot directly be used to reconstruct objects with sharp edges,a method for mesh piecewise reconstruction based on feature detection is proposed.It builds the object’s triangular grid model ...
