Leaf size in mosses is structurally constrained by cell dimensions and genome size

open access: yesPlant Biology, Volume 28, Issue 2, Page 420-431, March 2026.
Cell size and midribs are the main mechanical determinants of moss leaf size, which itself depends on growth form and genome size; together, these relationships underpin key aspects of moss ecology and performance. Abstract Leaf anatomy is a key factor determining plant ecology.

Hyper‐Reduced Model Based on the Proper Orthogonal Decomposition and the LU Factorization Applied to the Neutron Diffusion Eigenvalue Problem

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT An efficient method for solving large eigenvalue problems efficiently can be developed using hyper‐reduced order models, such as those arising from the LU Proper Orthogonal Decomposition (LUPOD). The LUPOD employs dominant orthogonal modes along with a flexible number of collocation points to establish a reduced scalar product, thereby ...

Designing polarization management devices by tilting subwavelength grating structures [PDF]

open access: yes, 2019
Subwavelength gratings (SWG) are periodic structures which behave as controllable homogeneous metamaterials. SWGs are extremely interesting when they are used in platforms with a limited choice of material refractive indices, enabling the design of a ...

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

open access: yesAmerican Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to

O tempo do arquivo: a decadência do museu e a poética da história

open access: yes, 2011
Neste artigo, estou interessado na instituição moderna do museu ocidental. Muitos museus tiveram seu começo no século XIX e persistem até hoje influenciando, além dos centros Europeus e Norte Americanos, o desenvolvimento subseqüente de outros museus ...

Biosynthesis of Silver Nanoparticles Using Black Pepper (Piper nigrum) Seed Extract and Evaluation of Their Cytotoxicity

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study reports the green biosynthesis of piperine‐functionalized silver nanoparticles from Piper nigrum seed extract, followed by comprehensive physicochemical characterization and in vitro cytotoxic evaluation. The results confirm successful nanocomposite formation and demonstrate a marked enhancement of cytotoxic activity against gastric cancer ...
