Options for Compression of radio interferometry data: lossy compression of visibilities and lossless compression of uv-visibility grids for the MHONGOOSE survey

Abstract Next generation radio astronomy telescopes are challenging existing data reduction paradigms. With ever more antennas, larger bandwidths, and sometimes multiple primary beams, they often generate more observed data products than can readily be stored long-term. Thus, dat...

Synthesis-Dependent Phase Evolution and Catalytic Behavior of Unsupported Iron Catalysts for CO2 Hydrogenation to C2-C4=

Iron-based catalysts are widely investigated for CO2 hydrogenation to light olefins due to their low cost, abundance, and ability to form oxidic and carbidic phases involved in the RWGS-FTS pathway. However, supports and promoters can obscure the intrinsic role of iron phase evol...

The challenge of out-of-distribution detection in motor imagery BCIs

Abstract Objective Machine Learning classifiers used in Brain-Computer Interfaces make classifications based on the distribution of examples on which they were trained. When exposed to EEG from unfamiliar classes they can only make blind guesses. Instead of allowing such guesses,...

Bittersweet dynamics from flowers to fruits: chemometric molecular networking reveals metabolic changes towards reduced toxicity over ontogeny in above-ground Solanum dulcamara chemotypes

Poisonous plants frequently deploy toxic metabolites in an organ- and ontogenetic-specific manner, yet the developmental dynamics of these plant specialised metabolites remain poorly understood. In the Solanaceae, steroidal glycosides (SGs), including steroidal glycoalkaloids (SG...

Oxidation-State-Modulated Cobalt Catalysts for Ambient Selective Hydrogenation of Bio-Derived Aldehydes: Toward Bio-Based Polyesters

Abstract Selective hydrogenation is a crucial process in the synthesis of chemical intermediates. Here, we report the efficient hydrogenation of 5-hydroxymethylfurfural (HMF) to 2,5-bishydroxymethylfuran (BHMF) over N-doped C-supported cobalt catalysts (CoNC) derived from ZIF-67...

In situ visualization of autophagy reveals the presence of vesicles at the expanding phagophore rim

The autophagy core machinery mediates the enclosure of cytosolic cargo destined for degradation in the lysosome. The Atg9-Atg2-Atg18 complex coordinates phagophore expansion via directed lipid transfer until closure of the phagophore rim. Using an Atg2 variant (Atg2-PM4) as a mod...

Director Expertise and Compliance to Corporate Social Responsibility Regulations

ABSTRACT Research Question/Issue This paper investigates whether assigning CSR‐specific expertise to the board committee legally responsible for CSR improves compliance with mandatory CSR law and shapes how firms organize that compliance. Research Findings/Insights Using Indian l...

‘I wanted the whole world to know … it’s just part of who I am’: sexual identity development and management among lesbian, gay and bisexual Chilean adults

This study explored how lesbian, gay, and bisexual adults in La Araucanía, a region in southern Chile, developed and managed their sexual identities. Twelve adults aged 30 to 41, who came of age during a time of limited LGBTQ+ visibility and legal recognition, participated in sem...

Spatially decoupled design and AI-driven optimization for thermal uniformity and nitridation resistance in NH3-fueled micro-tubular SOFCs

Ammonia-fueled micro-tubular solid oxide fuel cells (MT-SOFCs) offer a compact route for carbon-free power generation, but the endothermic NH 3 decomposition can cause thermal non-uniformity, and local NH 3 enrichment can increase the thermodynamic risk of Ni nitridation in the a...

Hegel, Autonomy, and Social Freedom

Abstract This paper challenges a prominent interpretation of Hegel’s theory of recognition according to which Hegel’s account of recognition resolves what has been called the ‘paradox of autonomy’ by socializing the act of self-legislation. The paradox arises because autonomy see...

Genome-wide analysis of social behaviour across social domains, reporters and developmental stages: a meta-regression approach

Abstract Social behaviour is a heritable trait linked to well-being and mental health, yet it varies across social context, including social domains, informants and development, which may shape its underlying genomic architecture. Here, we conducted a genome-wide meta-regression...

Relationship Breaker? Unplanned Births and Relationship Dissolution

This study explores the association between unplanned pregnancies resulting in a birth and relationship dissolution in the Netherlands. Using prospective, population-based birth cohort data from Rotterdam, the second largest city in the Netherlands, it finds that couples with an...

A global view on educational differences in career success: Organizational sponsorship, accumulated advantage, and the schooled society

Despite education's dominance in the globalized knowledge economy, the ways and reasons why education impacts subjective and objective career success remain the object of debate. We propose a three-level contextual model to explain the effect of education on job satisfaction and...

Inositol Hexakisphosphate Promotes Open Pore State in HIV Capsid Protein Lattice by Reconfiguring Subunit Contacts

Abstract The mature human immunodeficiency virus (HIV-1) capsid is composed of approximately 250 capsid protein hexamers, each containing a central pore delimited by a β-hairpin and an α-helix from each monomer. The cellular metabolite inositol hexakisphosphate (IP6) binds this p...

Toward actionable biomarkers in psychiatry: a collaborative roadmap for precision clinical trials. An ACNP position paper

Abstract Psychiatric drug development remains constrained by diagnostic heterogeneity, insufficient and inconsistent drug response, high placebo response rates, and the absence of validated biomarkers that can reliably guide patient stratification, trial design, and regulatory de...

Bankruptcy Experience and Corporate Hedging

ABSTRACT We examine whether managers’ prior exposure to corporate bankruptcy shapes corporate risk‐management policies. Using detailed executive employment histories and hand‐collected derivative disclosures for a large sample of US public firms, we find that firms led by bankrup...

Testing antimitotic agents to induce diploid gametophytes for the production of sterile triploid sporophytes in sugar kelp (Saccharina latissima)

Abstract The development of non-reproductive seaweeds could alleviate environmental concerns associated with the upscaling of seaweed aquaculture and the deployment of genetically improved cultivars containing non-local genetic material. However, current means to produce triploid...

Supportive communities: how health and welfare contexts shape neighbor relationships across 29 countries with unequal public healthcare resources

Abstract This study investigates how personal health status and multiple forms of disadvantages are associated with instrumental and emotional relationships with neighbors across 29 countries. Using data from the International Social Survey Program and the Global Health Observato...

The role of the third sector in China’s agri-food transitions: Integrating transformative social innovation and the state–society paradigm

The third sector is increasingly recognised as a key driver of transformative change in the agri-food system, though its potential depends largely on the institutional context. This study integrates transformative social innovation theory with a state–society framework to examine...
