Curve complexes are rigid [PDF]

open access: yes, 2011
Any quasi-isometry of the curve complex is bounded distance from a simplicial automorphism. As a consequence, the quasi-isometry type of the curve complex determines the homeomorphism type of the ...

An Optimal Transport Approach to Robust Reconstruction and Simplification of 2D Shapes [PDF]

open access: yes, 2011
We present a robust 2D shape reconstruction and simplification algorithm which takes as input a defect-laden point set with noise and outliers. We introduce an optimal-transport driven approach where the input point set, considered as a sum of Dirac ...

Volterra Filtering of Noisy Images of Curves [PDF]

open access: yes, 2002
How should one filter very noisy images of curves? While blurring with a Gaussian reduces noise, it also reduces contour contrast. Both non-homogeneous and anisotropic diffusion smooth images while preserving contours, but these methods assume a single local orientation and therefore they can merge or distort nearby or crossing contours. To avoid these

Robust reconstruction of curved line structures in noisy point clouds

open access: yesVisual Informatics, 2021
Point-based geometry representations have become widely used in numerous contexts, ranging from particle-based simulations, over stereo image matching, to depth sensing via light detection and ranging. Our application focus is on the reconstruction of curved line structures in noisy 3D point cloud data.

Inflation persistence, noisy information and the Phillips curve

open access: yesDocumentos de Trabajo, 2023
A vast literature has documented how US inflation persistence has fallen in recent decades, but this finding is difficult to explain in monetary models. Using survey data on inflation expectations, I document a positive co-movement between ex-ante average forecast errors and forecast revisions (suggesting forecast sluggishness) from 1968 to 1984, but ...

High Order Side-Channel Security for Elliptic-Curve Implementations

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2022
Elliptic-curve implementations protected with state-of-the-art countermeasures against side-channel attacks might still be vulnerable to advanced attacks that recover secret information from a single leakage trace.

Lithium-Ion Battery State of Health Estimation Based on Feature Reconstruction and Transformer-GRU Parallel Architecture

open access: yesEnergies
Estimating the state of health of lithium-ion batteries in energy storage systems is a key step in their subsequent safety monitoring and energy optimization management.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Improved river flow and random sample consensus for curve lane detection

open access: yesAdvances in Mechanical Engineering, 2015
Accurate and robust lane detection, especially the curve lane detection, is the premise of lane departure warning system and forward collision warning system.
