Radiolysis of ZrO2 Surface Modified with Polyphenols

Abstract The surface of ZrO2 was modified with various aromatic polyphenols to study their impact on the surface chemistry induced by γ radiolysis. Molecular hydrogen (H2) production in the radiolysis of water adsorbed on zirconium oxide (ZrO2) is enhanced over that observed in b...

Entomological and epidemiological trends during 5 years of combined indoor residual spraying and standard insecticide-treated nets in Kiremba, a malaria endemic site of Burundi

In Burundi, malaria due to Plasmodium falciparum is the leading cause of outpatient visit and hospital mortality. Anopheles gambiae s.l. and An. funestus s.l. are the primary malaria-transmitting vectors. The World Health Organization (WHO) recommends large-scale insecticide-trea...

Bhygnn+: unsupervised representation learning for heterophilic hypergraphs

Abstract Hypergraph neural networks (HyGNNs) have demonstrated remarkable success in modeling higher-order relationships among entities. However, their performance often degrades on heterophilic hypergraphs, where nodes connected by the same hyperedge tend to have dissimilar sema...

Response and Failure of Los Grillos Bridge to a Slow-Moving Landslide

Abstract A reconnaissance mission was organized by the American Concrete Institute, Committee 133, to visit the Los Grillos Bridge in Colombia on September 13, 2023. The bridge is a post-tensioned cast-in-place segmental cantilever structure featuring a box girder spanning 180 m....

Shaping Collaborations with Algorithms: How Agency and Heterogeneity Criteria Influence Team Formation and Outcomes

Across professional networking platforms, scientific collaboration networks, co-founder matching tools, and workplace collaboration platforms, algorithms increasingly shape how individuals find, evaluate, and connect with potential collaborators. These systems create tensions bet...

Uncovering Disparities in Rideshare Drivers’ Earning and Work Patterns: A Case Study of Chicago

Ride-sharing services are reshaping urban mobility but raising concerns around fairness, safety, and driver working conditions. This mixed-methods study combines large-scale analysis of Chicago’s Trip Network Provider data (2018–2023) with qualitative interviews and reconstructed...

Domain-Encoded Chirality in Carbon Nanomaterials from Structural Origins and Chiroptical Responses to Biological Effects

Abstract Chirality offers a powerful but underdeveloped design principle for regulating the optical, molecular, and biological behavior of carbon nanomaterials. Unlike small molecules, whose handedness is typically defined by discrete stereocenters, carbon nanomaterials can encod...

Entropy stable numerical schemes for divergence diminishing Chew, Goldberger & low equations for plasma flows

Chew, Goldberger & Low (CGL) equations are a set of hyperbolic PDEs with non-conservative products used to model the plasma flows, when the assumption of local thermodynamic equilibrium is not valid, and the pressure tensor is assumed to be rotated by the magnetic field. This res...

Group postpartum care improves mental health among postpartum women: a randomized controlled trial in Ghana

Despite the significant contribution of poor perinatal mental health to maternal morbidity and mortality, mental health care is often overlooked and not prioritized during postpartum care in many developing countries. In a parallel randomized controlled trial in Ghana, we tested...

RESTORING A HOMERIC QUOTATION TO THE POETICS VIA THE ARABIC ARISTOTLE

Abstract This article aims to elucidate the oblique insight that the Arabic translation can offer on Aristotle. In the case of Poetics 1461a29–30, the Arabic evidence supports a variant rightly disregarded as corrupt by modern editors. The Arabic rendering of the erroneous varian...

Probing EFT breakdown in the tails of $$W^+ W^-$$ observables

Abstract We test clipping effective field theory (EFT) simulations as a method of ensuring EFT validity. The procedure imposes that, at the level of the simulation, the invariant mass of a $$W^+W^-$$ W + W - pair $$M_{WW}$$ M WW is less than the new physics scale $$\Lambda $$ Λ ....

COMPUTABLE SCOTT SENTENCES AND THE FRIEDMAN–STANLEY EMBEDDING

Abstract Friedman and Stanley [9] developed the notion of Borel reducibility and illustrated its use in comparing classification problems for some familiar classes of countable structures. For many embeddings, the fact that the embedding is 1–1 on isomorphism types is explained b...

General and Special Providence in Contemporary Accounts of Spanish New World Inflation

While recent scholarship has explored the theological foundations of modern economic ideas, it has focused almost exclusively on general or ordinary providence (God’s action through secondary, natural causes) at the expense of special or extraordinary providence (God’s action in...

Expanding the Utility of Colistin Adjuvants To Encompass Next-Generation Polymyxins against Polymyxin-Resistant Acinetobacter baumannii and Klebsiella pneumoniae

Abstract Current treatment options for multidrug-resistant (MDR) Gram-negative infections are effectively limited to last-resort antibiotics, such as the polymyxins. Clinical use of polymyxins remains limited due to significant nephrotoxic side effects, and is further limited as...

Hyporheic eDNA Removal Outweighs Water Column Degradation in a Natural River

Abstract Advances in the measurement of environmental DNA (eDNA) have transformed biodiversity monitoring in aquatic ecosystems. However, linking eDNA concentrations in streams and rivers to species abundance remains challenging as flowing water, streambed retention, and degradat...

Somebody has to 'step up' and do the hard leadership jobs in academia

Renowned Chemist Catherine Murphy, Department Head at the University of Illinois, Urbana-Champaign, talks about the all-important job of being a Department Chair or Head. This is a copy of a post published in the Epistimi blog series at: https://www.epistimi.org/blog/somebody-has...

On definable groups in real closed fields with a generic derivation, and related structures

We study finite-dimensional groups definable in models of the theory RCF ∂ of real closed fields with a generic derivation (also known as CODF , the theory of closed ordered differential fields [28]). We prove that any such group Γ definably embeds in a “canonical” semialgebraic...

Side-Chain Grafting Frequency Controls Trap Formation and Polaron Mobility in Organic Mixed Conductors

Abstract Organic mixed ionic–electronic conductors (OMIECs) are π-conjugated polymer–electrolyte composites that support coupled ionic and electronic transport, making them candidates for bioelectronics, electrochemical sensors, and energy storage devices. Despite growing interes...

Model Falsification for Predicting Dynamical Responses of Uncertain Structural Systems

Abstract Accurate prediction of the dynamical response of a structural system depends on appropriate modeling of that system. However, modeling becomes increasingly challenging when numerous candidate models are available to describe the system behavior. Although different model...

The impact of climate and habitat on body shape and size evolution in charontid whip spiders

Abstract Environmental shifts often dictate Arthropod morphological evolution, yet certain lineages maintain remarkably conserved body plans across diverse habitats. Whip spiders (Amblypygi) emerged over 300 Ma and exhibit striking morphological conservatism; nonetheless, what dr...
