Reading Dürer in Late Sixteenth‐Century Padua: Matteo Macigni (ca. 1510–1582), His Library and the Annotated Institutionum geometricarum (Paris, 1535)

Renaissance Studies, EarlyView.
ABSTRACT This article contributes to the history of material culture and intellectual biography by definitively identifying the Paduan scholar Matteo Macigni (ca. 1510–1582) as the author of the annotations found in a 1535 copy of Albrecht Dürer’s Institutionum geometricarum currently preserved in Vicenza.

Computing abelian subalgebras for linear algebras of upper-triangular matrices from an algorithmic perspective

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper, the maximal abelian dimension is algorithmically and computationally studied for the Lie algebra hn, of n×n upper-triangular matrices. More concretely, we define an algorithm to compute abelian subalgebras of hn besides programming its ...

How Food Geometry and Toughness Influence Ingestive Patterns in Lemurs

American Journal of Primatology, Volume 88, Issue 7, July 2026.
Initial bite placement is influenced by food toughness and geometry. Species‐specific feeding strategies reflect differences in masticatory morphology and functional flexibility. Lemur catta is more likely to use the postcanine tooth row; Propithecus verreauxi prefers anterior biting. ABSTRACT We investigate the extent to which food toughness, geometry,

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

Bulletin 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 ...

Isotopies of complete minimal surfaces of finite total curvature

Journal 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 ...

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...
