Channel-wise Topology Refinement Graph Convolution for Skeleton-Based Action Recognition [PDF]

open access: yesIEEE International Conference on Computer Vision, 2021
Graph convolutional networks (GCNs) have been widely used and achieved remarkable results in skeleton-based action recognition. In GCNs, graph topology dominates feature aggregation and therefore is the key to extracting representative features.

Reversing orientation homeomorphisms of surfaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2021
Let $M$ be a connected compact orientable surface, $f:M\to \mathbb{R}$ be a Morse function, and $h:M\to M$ be a diffeomorphism which preserves $f$ in the sense that $f\circ h = f$. We will show that if $h$ leaves invariant each regular component of each

Using the Evolution Operator to Classify Evolution Algebras

open access: yesMathematical and Computational Applications, 2021
Evolution algebras are currently widely studied due to their importance not only “per se” but also for their many applications to different scientific disciplines, such as Physics or Engineering, for instance.

Kibble–Zurek scaling due to environment temperature quench in the transverse field Ising model

open access: yesScientific Reports, 2023
The Kibble–Zurek mechanism describes defect production due to non-adiabatic passage through a critical point. Here we study its variant from ramping the environment temperature to a critical point. We find that the defect density scales as $$\tau ^{-d\nu

How Molecular Topology Can Help in Amyotrophic Lateral Sclerosis (ALS) Drug Development: A Revolutionary Paradigm for a Merciless Disease

open access: yesPharmaceuticals, 2022
Even if amyotrophic lateral sclerosis is still considered an orphan disease to date, its prevalence among the population is growing fast. Despite the efforts made by researchers and pharmaceutical companies, the cryptic information related to the ...

Smooth approximations and their applications to homotopy types

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2020
Let $M, N$ the be smooth manifolds, $\mathcal{C}^{r}(M,N)$ the space of ${C}^{r}$ maps endowed with the corresponding weak Whitney topology, and $\mathcal{B} \subset \mathcal{C}^{r}(M,N)$ an open subset.
