On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences
Mathematische Nachrichten, Volume 299, Issue 8, Page 2087-2102, August 2026.ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

Novelty for the flora of Espírito Santo, Brazil: a new species of Ouratea Aubl. (Ochnaceae)
Nordic Journal of Botany, Volume 2026, Issue 8, August 2026.Here, we describe and illustrate the new species Ouratea oberdanii Fraga & Deccache, which is named after Dr Oberdan José Pereira. This new species is found in the mountainous regions of the evergreen Atlantic Forest in the Brazilian state of Espírito Santo. Ouratea oberdanii is similar to O. linearis (A.Gray) Sastre & Offroy and O.

The Role of Magmatic Styles in Planetary Thermal Evolution Models
Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Previous studies that investigated the effects of magmatism on the interior dynamics, in particular for Earth‐sized planets, suggest that magmatism leads to more efficient mantle cooling. However, the extent to which different magmatic styles influence the thermal evolution of planets, and in particular smaller rocky bodies, has not yet been ...

Earth and Space Science, Volume 13, Issue 7, July 2026.Abstract Spectral and hyperspectral data provide essential information on the surface composition of rocky planetary bodies, through which we can reconstruct and understand their origin and geologic evolution. In this field, applications of advanced tools, such as machine learning‐based algorithms, are steadily increasing.

Groundwater, Volume 64, Issue 4, Page 441-456, July/August 2026.Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Conversão agroecológica. [PDF]
, 2008 O processo de mudança do modelo de agricultura convencional, predominantemente praticada pelos agricultores atualmente, para a adoção de princípios agroecológicos, não se viabiliza apenas com a troca de insumos nos sistemas de produção, ou seja, deixar ...

Ecology and Evolution, Volume 16, Issue 6, June 2026.The biology of gall‐forming fergusoninid flies and their obligate nematode mutualists suggests strict vertical transmission of nematodes between fly generations. Using mitochondrial sequence data to associate fly and nematode haplotypes, we found widespread intraspecific horizontal transfer in multiple species.

On the bivariate Padovan polynomials matrix [PDF]
, 2023 In this paper, we intruduce the bivariate Padovan sequence we examine its various identities. We define the bivariate Padovan polynomials matrix. Then, we find the Binet formula, generating function and exponential generating function of the bivariate ...
