Nilpotent Approximations of Sub-Riemannian Distances for Fast Perceptual Grouping of Blood Vessels in 2D and 3D [PDF]

, 2017
We propose an efficient approach for the grouping of local orientations (points on vessels) via nilpotent approximations of sub-Riemannian distances in the 2D and 3D roto-translation groups $SE(2)$ and $SE(3)$.

The Future of MXene Fibers

Advanced Materials, EarlyView.
This perspective explores the diverse applications of MXene fibers, including those often overlooked in fiber‐focused studies. It emphasizes the critical need to address challenges in synthesis, scalability, and long‐term stability to unlock their full potential in real‐world applications. Abstract Since the first report on MXene‐coated fibers in 2017,

Fiber-Flux Diffusion Density for White Matter Tracts Analysis: Application to Mild Anomalies Localization in Contact Sports Players

, 2017
We present the concept of fiber-flux density for locally quantifying white matter (WM) fiber bundles. By combining scalar diffusivity measures (e.g., fractional anisotropy) with fiber-flux measurements, we define new local descriptors called Fiber-Flux ...

Biocompatibility and Long‐Term Stability of DNA‐Based Organic Mixed Conductors for Bioelectronics

Advanced Materials Interfaces, EarlyView.
The biocompatibility and long‐term stability of DNA‐based mixed ionic‐electronic conductors are investigated. In vitro cytotoxicity and cell viability are assessed using flow cytometry assay on primary mouse fibroblasts cultures. The biocomposites are integrated into organic electrochemical transistors (OECTs) to determine the stability of their ...

Bi-Plane X-ray coronary 3D reconstruction for flow velocity assessment [PDF]

, 2009
In coronary angiography the coronary blood flow velocity can be assessed by tracking a contrast agent in an image sequence. The contrast agent flow velocity is used to estimate the functional behavior of the coronary arteries using TIMI frame count (TFC).

Curve Matching Using the Fast Marching Method [PDF]

, 2003
Common techniques for curve alignment find a solution in the form of a shortest network path by means of dynamic programming. In this paper we present an approach that employs Sethian’s Fast Marching Method to find the solution with sub-resolution accuracy and in consistence with the underlying continuous problem.
