Terahertz Chiral Metamaterials Enabling Broadband Polarization Conversion Using Polarization Guiding Effect

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
A broadband terahertz polarization rotator consisting of twistingly stacked silicon–air metagratings is designed based on the polarization guiding effect and experimentally shown to achieve 90° linear polarization rotation for both TE and TM incidences.

Trust‐region filter algorithms utilizing Hessian information for gray‐box optimization

AIChE Journal, Volume 72, Issue 5, May 2026.
Abstract Optimizing industrial processes often involves gray‐box models that couple algebraic glass‐box equations with black‐box components lacking analytic derivatives. Such systems challenge derivative‐based solvers. The classical trust‐region filter (TRF) algorithm provides a robust framework but requires extensive parameter tuning and numerous ...

From transporter to motor: Evolutionary and structural insights into the emergence of prestin's area‐motor activity in mammals

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Prestin, a member of the SLC26A family, is essential for the electromotility of mammalian outer hair cells, converting voltage changes into mechanical work. In contrast, nonmammalian orthologues function as anion transporters. To investigate the molecular and structural basis of this functional divergence, we performed ancestral sequence ...

Gregorio y Francisco Esparza: hermanos enfrentados ante la independencia de Texas, 1835-1836 Gregorio and Francisco Esparza: Brothers Who Fought Each Other During the Independence of Texas, 1835-1836

Secuencia, 2012
En 1836 el ejército mexicano tomó el fuerte de El Álamo, en las afueras de San Antonio. Todos sus defensores, que combatían por la independencia de Texas, murieron en la acción, entre ellos Gregorio Esparza, un nativo de esa ciudad.

ConforFold recovers alternative protein conformations beyond MSA subsampling

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Conformational changes underlie many aspects of protein function, yet current structure prediction tools remain limited in their ability to systematically sample structural ensembles. Here, we present ConforPSSP and ConforFold, a combined framework that integrates secondary‐structure sampling into a deep learning‐based prediction to recover ...

Relationships and differences between the Triassic ammonoid successions of northwestem Sonora, Mexico, and west-central Nevada, U.S.A.

Revista Mexicana de Ciencias Geológicas, 2019
The Antimonio Formation exposed in the Sierra del Álamo, northwestern Sonora, consists of an Upper Permian-Lower Jurassic marine succession of sedimentary rocks that disconformably overlies  the Guadalupian-age Monos Formation… in order to continue ...

Assessment of soil slurry saturation and slurry infiltration in pig slurry storage ponds using electrical resistivity tomography

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Effective management of pig slurry in semi‐arid settings is critical to protect soils and aquifers. This study integrates multi‐profile electrical resistivity tomography (ERT) compiled into stitched 3D volumes with a calibration based on modified Archie's law derived from laboratory resistivity–moisture tests to obtain semi‐quantitative soil ...

Constraining the Hydration of Clay Minerals and Abundances of Amorphous Phases in Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Both water and organic matter are required for the development and persistence of life. Phyllosilicates (clay minerals) have high surface areas that easily sorb water and organic matter. The Curiosity rover has investigated several hundred meters of stratigraphy in Gale crater, including where clays were detected from orbit.
