Financial Climate‐Risk Measurement, Impact Funds, and Green Transitions

open access: yesJournal of Accounting Research, Volume 64, Issue 4, Page 1867-1903, September 2026.
ABSTRACT Regulators are contemplating or mandating precise measurement of financial climate‐risk exposure to promote sustainable investments. We show that such mandates can be counterproductive in the presence of social funds that catalyze change by subsidizing the adoption of cleaner production technologies.

Radiografía X del cielo γ [PDF]

open access: yes, 2020
Esta Tesis se basa mayormente en observaciones en rayos-X y óptico, llevadas a cabo con el X-ray Telescope (XRT) a bordo del satélite Neil Gehreils Swift, y con un número de telescopios ópticos en tierra; todas asociadas a objetos observados por el telescopio de rayos-γ Large Area Telescope (LAT) a bordo del satélite Fermi.

Thermal expansion of FeWO4 (ferberite) and FeWO4:Fe2WO6 (7:1): a comparative X‐ray and neutron diffraction study

open access: yesJournal of Applied Crystallography, Volume 59, Issue 4, Page 1238-1246, August 2026.
Temperature‐dependent single‐crystal X‐ray, powder X‐ray and neutron diffraction measurements reveal the thermal expansion behavior of FeWO4 from 2 to 1123 K. Significant differences between natural ferberite and a FeWO4:Fe2WO6 composite highlight the influence of multiphase and microstructural effects on derived thermoelastic parameters.The thermal ...

Kinetic parameter prediction using neural networks identifies limitations to C4 photosynthesis

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1578-1594, August 2026.
Schematic overview of the generation of artificial training data and training of neural networks in C4TUNE. Summary Kinetic models of photosynthesis enable time‐resolved predictions of traits related to this key process and provide the means to identify factors limiting photosynthesis.

Uso de los rayos X en la guerra hispano-cubano-norteamericana

open access: yesRevista Cubana de Medicina Militar, 2023
En Cuba, el primer departamento de rayos X se inauguró en el año 1907 por Francisco Domínguez Roldán. Poco se divulga un contacto previo durante el siglo XIX, en la guerra hispano-norteamericana.

Antisense reduction in NADP‐ME in the C4 species Flaveria bidentis alters stomatal sensitivity to intercellular [CO2]

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1585-1597, May 2026.
Summary Stomata have the crucial role of balancing the uptake of CO2 for photosynthesis and water loss via transpiration by adjusting their aperture. In C3 plants, coordination between photosynthesis and stomatal conductance can be disrupted by mutations in Calvin–Benson–Bassham (CBB) cycle expression, but it is not clear whether the disruption of the ...

A Molecular Hybrid 2D/3D Carbon Allotrope: Synthesis of Adamanphene

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
Adamanphene fuses diamond and graphene at the molecular level. An adamantane core anchors four hexabenzocoronene nanographenes into a rigid tetrahedral architecture, giving rise to a porous π‐stacked solid with electronically isolated chromophores and aggregation‐induced emission.
