Link prediction with hyperbolic geometry [PDF]

open access: goldPhysical Review Research, 2020
Link prediction is a paradigmatic problem in network science with a variety of applications. In latent space network models this problem boils down to ranking pairs of nodes in the order of increasing latent distances between them. The network model with

Evolution of cortical geometry and its link to function, behaviour and ecology

open access: yesNature Communications, 2023
Studies in comparative neuroanatomy and of the fossil record demonstrate the influence of socio-ecological niches on the morphology of the cerebral cortex, but have led to oftentimes conflicting theories about its evolution.

Multi-Link MIMO Channel Modeling Using Geometry-Based Approach [PDF]

open access: greenIEEE Transactions on Antennas and Propagation, 2011
Geometry-based stochastic channel models (GSCMs) are extended to support multi-link simulations by applying the concept of common clusters. This novel approach aims to control the correlation between different links, inter-link correlation, by adjusting the amount of power simultaneously propagating via the same clusters in the different links.

Centerpoints: A Link between Optimization and Convex Geometry [PDF]

open access: yesSIAM Journal on Optimization, 2015
We introduce a concept that generalizes several different notions of a "centerpoint" in the literature. We develop an oracle-based algorithm for convex mixed-integer optimization based on centerpoints.

Rethinking the link between matter and geometry [PDF]

open access: yesPhysical Review D, 2018
In the present manuscript, I examine an intriguing relation at the classical level between General Relativity and a theory where matter couples uniquely multiplicatively to geometry in the Lagrangian density.

Relating geometry descriptions to its derivatives on the web [PDF]

open access: yesProceedings of the 2019 European Conference on Computing in Construction, 2019
Sharing building information over the Web is becoming more popular, leading to advances in describing building models in a Semantic Web context. However, those descriptions lack unified approaches for linking geometry descriptions to building elements ...

A link invariant from the symplectic geometry of nilpotent slices [PDF]

open access: green, 2004
We define an invariant of oriented links in S 3 using the symplectic geometry of certain spaces which arise naturally in Lie theory. More specifically, we present a knot as the closure of a braid, which in turn we view as a loop in configuration space ...

Leveraging the nonuniform PSO network model as a benchmark for performance evaluation in community detection and link prediction

open access: yesNew Journal of Physics, 2018
Advances in network geometry pointed out that structural properties observed in networks derived from real complex systems can emerge in the hyperbolic space (HS).

Noncommutative Schwarzschild geometry and generalized uncertainty principle

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
We discuss a possible link between the deformation parameter $$\Theta ^{\mu \nu }$$ Θμν arising in the framework of noncommutative geometry and the parameter $$\beta $$ β of the generalized uncertainty principle (GUP). We compute the shift of the Hawking

Purcell’s Three-Link Swimmer: Assessment of Geometry and Gaits for Optimal Displacement and Efficiency [PDF]

open access: goldMathematics, 2021
This paper studies the displacement and efficiency of a Purcell’s three-link microswimmer in low Reynolds number regime, capable of moving by the implementation of a motion primitive or gait.
