Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

open access: yesAdvanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

¿PARADIGMAS O PARADIGMATITIS? ACERCA DE LOS INCONVENIENTES USOS DE ESTE CONCEPTO EN LA EPISTEMOLOGÍA PSICOLÓGICA

open access: yesRevista de Ciencias Sociales, 2013
Con base en una breve revisión acerca de los significados que le diera T.S. Kuhn a “paradigma”, incluyendo diversas relaciones de sentido con otras ideas suyas, se concluye primero que estas ideas no son aplicables al desarrollo de la Psicología.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Kuhn and the genesis of the “new historiography” of science [PDF]

open access: yes, 2010
In this paper I identify a tension between the two sets of works by Kuhn regarding the genesis of the “new historiography” of science. In the first, it could be said that the change from the traditional to the new historiography is strictly endogenous ...

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

The potato mop-top virus TGB2 protein and viral RNA associate with chloroplasts and viral infection induces inclusions in the plastids

open access: yesFrontiers in Plant Science, 2012
The potato mop-top virus (PMTV) triple gene block 2 (TGB2) movement protein fused to monomeric red fluorescent protein (mRFP-TGB2) was expressed under the control of the PMTV subgenomic promoter from a PMTV vector.
