On the Hausdorff dimension and Cantor set structure of sliding Shilnikov invariant sets

Matheus G. C. Cunha, Douglas D. Novaes, Gabriel Ponce

The concept of sliding Shilnikov connection has been recently introduced and represents an important notion in Filippov systems, because its existence implies chaotic behavior on a…

Signatures of infinite randomness in transport properties of disordered spin chains

L. F. C. Faria, Victor L. Quito, João C. Getelina +2

We study the spin transport properties of some disordered spin chains with a special focus on the distribution of the frequency-dependent spin conductivity. In the cases of interes…

Impact craters formed by spinning granular projectiles

Douglas Daniel de Carvalho, Nicolao Cerqueira Lima, Erick de Moraes Franklin

Craters formed by the impact of agglomerated materials are commonly observed in nature, such as asteroids colliding with planets and moons. In this paper, we investigate how the pr…

Robust Domain Misinformation Detection via Multi-modal Feature Alignment

Hui Liu, Wenya Wang, Hao Sun +2

Social media misinformation harms individuals and societies and is potentialized by fast-growing multi-modal content (i.e., texts and images), which accounts for higher "credibilit…

A robust numerical strategy for finding surface waves in flows of non-Newtonian liquids

Bruno Pelisson Chimetta, Erick de Moraes Franklin

Gravity-driven flows of liquid films are frequent in nature and industry, such as in landslides, lava flow, cooling of nuclear reactors, and coating processes. In many of these cas…

All-fiber broadband spectral acousto-optic modulation of a tubular-lattice hollow-core optical fiber

Ricardo E. da Silva, Jonas H. Osório, Gabriel L. Rodrigues +5

We demonstrate a broadband acousto-optic notch filter based on a tubular-lattice hollow-core fiber for the first time. The guided optical modes are modulated by acoustically induce…
