Deciphering Dynamic Self‐Healing for Crystallinity Control in β‐Ketoenamine‐Linked Covalent Organic Frameworks

ABSTRACT Covalent organic frameworks derived from triformylphloroglucinol (Tp‐COFs) represent a prominent branch of COFs due to their high potential in separation, energy storage, and optoelectronics. However, the development of Tp‐COFs is often hindered by limited crystallinity,...

Ultrahigh flow strength in shocked nanopolycrystalline diamond

Extreme pressures and temperatures create conditions that allow even hard and brittle materials to flow plastically. Despite extensive research, the limits of flow strength under such conditions remain uncertain, and the mechanisms driving deformation at the relevant stresses are...

Influence of the Size of the Metallacycle of P‐NHC Mn Complexes for the Hydrogenation of Esters

Chelate ring size is a key but underexplored parameter in the design of manganese‐based hydrogenation catalysts. Here, we report the synthesis and characterization of Mn(I) NHC–phosphine complexes [Mn‐5] C7 featuring a seven‐membered chelate ring and their application to the hydr...

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit ( Parus major ) territories across Europe

Urbanisation alters resource availability and exposes wildlife to novel environmental stressors, potentially driving phenotypic divergence. Carotenoid-based plumage colouration is a condition-dependent trait linked to dietary carotenoid acquisition and physiological allocation tr...

Learning-Based Methods and the Future of Numerical Ocean and Sea-Ice Modeling

The field of operational oceanography is undergoing a significant evolution with the increasing integration of artificial intelligence (AI) methods, which are complementing and, in some cases, redefining traditional numerical modeling approaches. This review explores how AI metho...

When Participation Becomes a Criterion: Developing an Analytical Framework for Participatory Science

Participatory science projects have multiplied in recent years, yet frameworks to analyse and evaluate them remain fragmented. While conventional research relies on standardized criteria, participatory research requires approaches that account for collaborative processes, governa...

Sugar metabolism drives shoot branching by repressing BRC1 through miR319 –targeted TCP4 in Rosa

Abstract The coupling between sugar availability and shoot branching is well established, yet the underlying molecular mechanisms remain largely unknown. Here, using genome-wide profiling, we characterized the sugar signalling pathways by identifying 10 microRNAs (miRNAs) repress...

Enhancement of mechanical performance in metakaolin-based geopolymer by cyclic loading and creep process in relation with microstructural evolution

Geopolymers are more and more widely used in engineering applications as low carbon construction materials. Their mechanical properties under monotonic loading have been widely investigated. However, there is still a crucial need to investigate their mechanical responses under cy...

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

ABSTRACT We describe the synthesis of a family of photoemissive linear Cu(I) complexes bearing mesoionic carbenes (MIC) and amido ligands of the general formula Cu(MIC)NR 2 (NR 2 = carbazolide, diphenylamide). Careful tuning of the electronic and structural properties of both lig...

SLC7A6OS Founder Mutation: A Rare Cause of Progressive Myoclonus Epilepsy Dated to 1100 Years Ago

BACKGROUND: SLC7A6OS c.191A>G is a rare, autosomal recessive cause of progressive myoclonus epilepsy (PME). The c.191A>G variant, first discovered in two families from Türkiye and Portugal, was recently identified in three additional probands from the USA, all of Puerto Rican anc...

Not speaking my language: playback experiments reveal early-orphaned human-reared adult cheetahs lack interest in species-specific vocalizations

Abstract Early adult models, particularly the mother, play an essential role in tuning perception to build the multimodal representation of species-specific social signals, especially in mammals. Therefore, early maternal loss adversely impacts social integration in mammals. More...

Tracking the Mechanism of Electrocatalytic Hydrodeoxygenation of Propylguaiacol by Electrochemical Membrane-Inlet Mass Spectrometry

Abstract Lignocellulose-derived bio-oils require hydrodeoxygenation (HDO) to reduce their oxygen content for integration into conventional fuels. Electrocatalytic HDO (eHDO) offers a sustainable alternative to traditional high-temperature, high-pressure processes, but its mechani...

Measurement error and peer effects in networks

In many practical applications, only noisy proxies for the true regressors are available, which is commonly believed to induce an attenuation bias. In the linear-in-means model, however, estimated peer effects might be inflated, potentially leading to false positives. This paper...

Neurofeedback-induced network plasticity in motor and default mode networks correlates with motor recovery after stroke

Abstract Stroke often results in long-term motor impairments, necessitating innovative rehabilitation strategies. Neurofeedback (NF) has emerged as a promising tool to promote functional recovery after stroke by enabling patients to modulate targeted brain activity. In this study...

Electrical signalling beyond diffusion-limited microbial interactions

Abstract Ecological communication is traditionally interpreted through diffusion-limited chemical signalling. Here, we argue that bioelectricity provides a complementary dimension of microbial ecological interaction, arising from ion-driven electrical signalling between responsiv...

General heat release rate surrogates for NH3/H2/N2 and H2 flames using Raman/Rayleigh/LIF accessible species

Accurate estimation of the heat-release rate (HRR) is essential for understanding and controlling ammonia–hydrogen combustion, yet conventional experimental surrogates are strongly dependent on operating conditions and typically rely on radicals measured by laser-induced fluoresc...

Photovoltaic panels affect arthropod and plant communities: a systematic review

Due to climate change, photovoltaic facilities are being rapidly scaled up. However, such a development can come at a cost for biodiversity. We conducted a systematic review, including a critical appraisal, and meta-analyses to better understand the effects of photovoltaic panels...

Can one hear the shape of a crack in a drum? Spectral fingerprints and a data-driven perspective

Abstract This paper investigates whether the shape of a crack in a membrane can be identified from the corresponding Laplace spectrum. To this end, analytical results are derived using the short-time asymptotic expansion of the heat trace, a fundamental spectral invariant. The an...

HIPK2 loss promotes TDP-43 cytoplasmic mis-localization through MAPK-pathway and is associated with TDP-43 proteinopathy in vivo

Abstract Homeodomain Interacting Protein Kinase 2 (HIPK2) is a stress sensor kinase that has emerged as a key regulator of neuronal homeostasis and survival. In this study, we investigated the role of HIPK2 in neurodegeneration using both in vivo and in vitro models. We show that...

Computer-Aided Entrainer Design for Extractive Distillation Using Infinitely Sharp Splits

Abstract We present an integrated product-process design framework for ranking heavy entrainer candidates for minimum-boiling azeotrope separation, corresponding to the Serafimov class (1.0-1a), the most common such case. The framework combines computer-aided molecular design (CA...
