Curvilinear Integral Theorems for Monogenic Functions in Commutative Associative Algebras [PDF]

open access: yesAdvances in Applied Clifford Algebras, 2015
We consider an arbitrary finite-dimensional commutative associative algebra, $\mathbb{A}_n^m$, with unit over the field of complex number with $m$ idempotents. Let $e_1=1,e_2,e_3$ be elements of $\mathbb{A}_n^m$ which are linearly independent over the field of real numbers. We consider monogenic (i.e.

A gradient field approach to modelling fibre-generated spatial point processes [PDF]

open access: yes, 2011
A new non-parametric model is introduced for point processes that are clustered along curves or fibres, with additional background noise. The model identifies random curves as integral lines of a gradient field.

An analog of the Cauchy formula for certain Beltrami equations

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
The Beltrami differential equations are intrinsic generalizations of the Cauchy–Riemann system in complex analysis. Their solutions generalize holomorphic functions. As known, solutions to many problems of the complex analysis are based on application of

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

open access: yesAdvanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Analysis of the Post-Critical Deformation State of Curvilinear Integral Stiffening of a Thin-Walled Structure Subjected to Torsion

open access: yes, 2020
The paper presents an innovative concept of integral stiffening of the thin-walled structures based on the use of curvilinear elements. The analyzed system in the form of a thin-walled spatial structure was subjected to a non-linear numerical analysis ...

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors

open access: yesAdvanced Intelligent Systems, EarlyView.
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...
