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.

Numerical study on the behavior of link-to-column connections in eccentrically braced frames [PDF]

open access: yesNumerical Methods in Civil Engineering, 2014
Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of
