Heavier Alkyne‐Ni0 Complexes, [R2E2·Ni] (E = Sn, Pb), Exhibiting σ‐Complex Character

open access: yesAngewandte Chemie, EarlyView.
Using a reductive group elimination strategy, heavier alkyne (LEEL; E = Sn, Pb) complexes of Ni0 are accessed. In contrast to classical alkyne coordination, these systems are best described as σ‐complexes, driven by ligand‐induced constraints and the established poor π‐bonding in heavier alkyne analogues.

Enhancing Atomic‐Resolution in Electron Microscopy: A Deep Learning Denoiser Operating in the Frequency Domain

open access: yesAdvanced Intelligent Systems, EarlyView.
The newly developed AI‐automated Fast Fourier Transform denoising algorithm surpasses conventional real‐space methods by revealing even light atoms otherwise hidden in noisy backgrounds. Atomic resolution electron microscopy has become an essential tool for many scientific fields, when direct visualization of atomic arrangements and defects is needed ...

Defect‐Guided Assembly of Aperiodic and Flexible Metal–Organic Frameworks From Pre‐Formed Cages

open access: yesAngewandte Chemie, EarlyView.
A cage‐directed strategy is used to program topologically correlated defects and induce aperiodicity in HKUST‐1‐type MOFs. A missing carboxylate group in the linker drives the formation of Cu‐vacancy domains, while Rh(II) cages spatially confine these defects.

La práctica del caleado como marcador material de agencia campesina durante la revolución agraria de la Edad Moderna en el Cantábrico oriental

open access: yes
Las transformaciones agrarias ocurridas durante la Edad Moderna (siglos XVI-XIX) en el Cantábrico oriental ofrecen un marco óptimo para analizar la agencia campesina a través de sus huellas materiales. Estos cambios, tradicionalmente explicados desde la narrativa de la 'revolución del maíz', supusieron una importante reorganización de los paisajes ...

¿Es conveniente despenalizar la tenencia y el porte de las armas en una sociedad violenta? reflexiones a partir de la teoría de la agencia material de Lambros Malafouris

open access: yesPensamiento Jurídico
En artículo Examina la despenalización de la venta, tenencia y porte de armas, contrastando el instrumentalismo de los artefactos defendido por el PartidoRepublicano estadounidense, según el cual ellas son herramientas sin intencionalidad, y el determinismo propio del Partido Demócrata, que sostiene que ellasson agentes posibilitadores de las acciones ...

Disentangling Aleatoric and Epistemic Uncertainty in Physics‐Informed Neural Networks: Application to Insulation Material Degradation Prognostics

open access: yesAdvanced Intelligent Systems, EarlyView.
Physics‐Informed Neural Networks (PINNs) provide a framework for integrating physical laws with data. However, their application to Prognostics and Health Management (PHM) remains constrained by the limited uncertainty quantification (UQ) capabilities.

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...
