Merge Tree Geodesics and Barycenters with Path Mappings

IEEE Transactions on Visualization and Computer Graphics, 2023
Comparative visualization of scalar fields is often facilitated using similarity measures such as edit distances. In this paper, we describe a novel approach for similarity analysis of scalar fields that combines two recently introduced techniques: Wasserstein geodesics/barycenters as well as path mappings, a branch decomposition-independent edit ...

Geophysical Investigations at the Artemision at Amarynthos of Euboea (Greece)

Archaeological Prospection, EarlyView.
ABSTRACT A combination of resistivity mapping and three‐dimensional electrical resistivity tomography (ERT) was used to investigate the subsurface of the sanctuary of Artemis Amarysia in Amarynthos, Euboea (Greece), an area where archaeological remains from the Bronze Age to the post‐Byzantine period are preserved.

Advancing Cave Survey Methods: High‐Precision Mapping in Drakotrypa Cave, Greece

Archaeological Prospection, EarlyView.
ABSTRACT Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features.

Salient Object Detection Based on Background Feature Clustering

Advances in Multimedia, 2017
Automatic estimation of salient object without any prior knowledge tends to greatly enhance many computer vision tasks. This paper proposes a novel bottom-up based framework for salient object detection by first modeling background and then separating ...

Geometry Sampling-Based Adaption to DCGAN for 3D Face Generation

Sensors, 2023
Despite progress in the past decades, 3D shape acquisition techniques are still a threshold for various 3D face-based applications and have therefore attracted extensive research.

Guidelines for Scale Development and Validation

Journal of Consumer Behaviour, EarlyView.
ABSTRACT Scales, serving as measurement instruments composed of carefully designed items intended to capture latent constructs, play a critical role in advancing consumer theory and marketing practice. Yet, developing and validating scales poses a formidable challenge due to the diverse methods required to ensure rigor and robustness.

Some fixed-point theorems for a pair of Reich-Suzuki-type nonexpansive mappings in hyperbolic spaces

Topological Algebra and its Applications, 2023
In this article, we prove some fixed-point results for a pair of Reich-Suzuki-type nonexpansive mappings in uniformly convex WW-hyperbolic spaces. We introduce a new iterative scheme and establish its convergence to the fixed points of a pair of Reich ...

Properties of an affine transport equation and its holonomy

, 2016
An affine transport equation was used recently to study properties of angular momentum and gravitational-wave memory effects in general relativity. In this paper, we investigate local properties of this transport equation in greater detail.

Isoperimetric inequalities on slabs with applications to cubes and Gaussian slabs

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We study isoperimetric inequalities on “slabs”, namely weighted Riemannian manifolds obtained as the product of the uniform measure on a finite length interval with a codimension‐one base. As our two main applications, we consider the case when the base is the flat torus R2/2Z2$\mathbb {R}^2 / 2 \mathbb {Z}^2$ and the standard Gaussian measure
