OpenCRG Models From Different Data Sources to Support Vehicle Simulations

IEEE Access, 2022
Digital twins of road surfaces support multiple engineering applications. Remote sensing technologies provide information from the entire surface of the pavement by high accuracy point clouds. Pavement errors and differences from designed geometry can be

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

PointGeo: Geometry Transformer for Point Cloud Analysis

CAAI Transactions on Intelligence Technology
Point cloud processing plays a crucial role in tasks such as point cloud classification, partial segmentation and semantic segmentation. However, existing processing frameworks are constrained by several challenges, such as recognising features in ...

Cosmological evolution and dark energy in osculating Barthel–Randers geometry

European Physical Journal C: Particles and Fields, 2021
We consider the cosmological evolution in an osculating point Barthel–Randers type geometry, in which to each point of the space-time manifold an arbitrary point vector field is associated.

Point derivation of partial geometries

European Journal of Combinatorics, 2003
The author generalizes a method for constructing partial quadrangles from generalized quadrangles. See \textit{F. De Clerck} and \textit{H. Van Maldeghem} [in Handbook of incidence geometry: buildings and foundations, 433--475 (1995; Zbl 0823.51010)] for the method and nomenclature.

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Particle physics from the noncommutative geometry point of view [PDF]

, 1993
Recent development in noncommutative geometry generalization of gauge theory is reviewed. The mathematical apparatus is reduced to minimum in order to allow the non-mathematically oriented physicists to follow the development in the interesting field of ...

Back to geometry: Efficient indoor space segmentation from point clouds by 2D–3D geometry constrains

International Journal of Applied Earth Observations and Geoinformation
This paper addresses the challenge of indoor space segmentation from 3D point clouds, which is essential for understanding interior layouts, reconstructing 3D structures, and developing indoor navigation maps.

Preferred Point Geometry and Statistical Manifolds

The Annals of Statistics, 1993
The authors introduce a mathematical object of a preferred point geometry. Its definition and use are based on two standpoints: to be as natural and simple as possible from both the statistical and the geometric viewpoint, and to reflect in a natural way the special status of the preferred point.
