Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.

Willmore‐Like Tori in Killing Submersions

open access: yesAdvances in Mathematical Physics, Volume 2018, Issue 1, 2018., 2018
The first variation formula and Euler‐Lagrange equations for Willmore‐like surfaces in Riemannian 3‐spaces with potential are computed and, then, applied to the study of invariant Willmore‐like tori with invariant potential in the total space of a Killing submersion.

Em direção ao ruído: loop de desaparecimentos ao rés do corpo

open access: yesPalíndromo
Este artigo se dedica a uma análise do disco Isto (2019), obra de Cildo Meireles realizada com a voz da locutora Íris Lettieri. Assim como em Isto o artista recorreu ao loop para reunir, sonoramente e sutilmente, ambos os lados do disco, a escrita deste

CURVATURE APPROXIMATION FROM PARABOLIC SECTORS

open access: yesImage Analysis and Stereology, 2017
We propose an invariant three-point curvature approximation for plane curves based on the arc of a parabolic sector, and we analyze how closely this approximation is to the true curvature of the curve.

Proper 3‐realizability and second cohomology of groups on two generators of finite order

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 7, July 2026.
Abstract Given an (infinite) finitely generated group G$G$, its first cohomology group H1(G;ZG)$H^1(G;{\mathbb {Z}}G)$ is free abelian and “counts” the number of ends of G$G$ which equals 1+rank(H1(G;ZG))$1 + rank (H^1(G;{\mathbb {Z}}G))$. The question whether or not for every finitely presented group G$G$ its second cohomology group H2(G;ZG)$H^2(G ...

A New Algebraic Approach to Decision Making in a Railway Interlocking System Based on Preprocess

open access: yesMathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
The safety of railway networks is a very important issue. Roughly speaking, it can be split into safety along lines and safety of railway facilities such as stations, junctions, yards, etc. In modern networks the safety along lines is controlled by automatic block systems that do not give clearance to trains to enter a section (block) until the latter ...

Isotopies of complete minimal surfaces of finite total curvature

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract Let M$M$ be a Riemann surface biholomorphic to an affine algebraic curve. We show that the inclusion of the space ℜNC∗(M,Cn)$\Re \mathrm{NC}_*(M,\mathbb {C}^n)$ of real parts of nonflat proper algebraic null immersions M→Cn$M\rightarrow \mathbb {C}^n$, n⩾3$n\geqslant 3$, into the space CMI∗(M,Rn)$\mathrm{CMI}_*(M,\mathbb {R}^n)$ of complete ...
