Adhesion investigation of waterborne and solventborne epoxy coatings on oil-contaminated and surface-corroded steel substrates

Epoxy coatings are widely used to protect steel structures; however, industrial substrates often retain residual corrosion products and organic contaminants after surface preparation. Waterborne (WB) epoxy coatings are generally considered less surface-tolerant than solventborne...

Delivering building demand flexibility for grid-interactive operation: from perception and cognition to decision, execution, and verification

As both buildings and power systems undergo rapid decarbonization, demand flexibility (DF) in buildings has emerged as a key enabler for renewable energy integration, grid reliability, energy resilience, and efficient and low carbon operation. By dynamically adjusting building en...

Anchors for Homology-Based Scaffolding

Homology-based scaffolding orders contigs based on conserved collinearity of homologous sequences across related species. Existing methods often rely on costly whole-genome alignments or show limited robustness when integrating multiple references. Here, we introduce an anchor-ba...

Assessing inter-model agreement in convection-permitting simulations of extreme winds for wind energy applications

Abstract. Convection-permitting models (CPMs) have great potential for wind energy applications such as wind energy planning, turbine design loads, and operational safety in a climate change context. In fact, compared to coarse-resolution models, they have an improved representat...

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, co...

Mechanical limits shape the eccentric form of rose prickles

Abstract Rose prickles are vegetal weapons familiar to most green-thumbed individuals. Their distinctive feature is an oval cross-section, which contrasts with the mostly circular shapes of natural and man-made stingers. However, the reason for their eccentricity remains poorly u...

Dynamic connectedness between commodity markets and investor sentiment in “ESG” labeled funds

Abstract This study explores the dynamic interactions between price shocks to commodity markets and investor demand, proxied by fund flows, in environmental, social, and governance (ESG)-labeled global equity and bond funds. By focusing on labeled funds, the analysis isolates the...

Development of material monitoring protocols for nature-inclusive designed concrete units in harbor-fronts

Abstract Human activities are putting stress on earth’s ecosystems, and with increasing populations in coastal zones, the pressure on the marine environments intensifies. To accommodate the increase in anthropogenic activities in these areas, concrete is often used to adapt the c...

Association between candidate genes and FRAX scores in postmenopausal women

Abstract Purpose Single nucleotide polymorphisms (SNPs) have been associated with BMD and bone fracture risk. The aim of this study was to assess the possible association between FRAX scores and specific SNPs in Italian osteopenic and osteoporotic postmenopausal women. Methods We...

Vigilant Algorithms and the Contagion of Risk in Automated Opioid Risk Assessment

Amid the ongoing opioid crisis, U.S. health systems have extended prescription monitoring interfaces with proprietary reports that provide clinicians with algorithmic risk scores to guide opioid decisions. However, little is known about how such tools shape clinical encounters, p...

Color Symmetry Breaking in a Nonlinear Optical Microresonator

ABSTRACT Spontaneous symmetry breaking leads to diverse phenomena across the natural sciences, from the Higgs mechanism in particle physics to superconductors and collective animal behavior. In photonic systems, the symmetry of light states can be broken when two optical fields i...

Enhanced and directional light emission from two-dimensional excitons using Mie voids

Abstract Controlling light emission at the nanoscale has important applications in solid-state lighting, displays, and quantum light sources. Achieving this control requires both enhanced local electromagnetic fields to boost emission intensity and engineered radiation patterns t...

Metagenomic Profiling of Diarrheagenic Escherichia coli Pathotypes Reveals Predominance of Diffusely Adherent and Enteroaggregative Subtypes and Mixed Signatures Among Under-Fives in Tanzania

Diarrheagenic Escherichia coli (DEC) is a leading enteric pathogen in children under five in sub-Saharan Africa, yet conventional targeted assays fail to capture mixed virulence signatures or provide quantitative context relative to E. coli carriage. We applied a virulence-aware...

A temporal differentiation program after birth delineates γδ T cell immunity

Type 1 and type 3 γδ T cells develop in the embryonic thymus, yet it is not known whether they continue to differentiate after birth in tissues. Here, we show that in the first week of life, intestinal γδ T cells up-regulated many T cell activation and type 3 genes, while the pos...

Interpretable Spectral Transformer for Raman-Based Bacterial Identification Across Species and Strains

Raman spectroscopy combined with machine learning offers a rapid, label-free approach for bacterial identification, but robust translation remains challenged by spectral variability, biological heterogeneity, and limited model interpretability. Here, we present an integrated eval...

Catalyst Screening for Low-Temperature Stabilization of Furfural: Effects of Sulfur Poisoning

Biomass-derived fast pyrolysis oil (PO) represents a promising alternative fuel for aviation and heavy transport. However, its high content of oxygenated organic molecules necessitates catalytic hydrodeoxygenation (HDO) before it is viable to be sent to a refinery. Single-step up...

Achieving micrometer-scale 4D X-ray tomography of living leaf tissue in the laboratory

A methodology for achieving micrometer-scale 4D X-ray lab microscopy of living leaf tissue was developed to overcome challenges associated with delicate tissues, radiation damage, and motion artifacts during in vivo imaging. The study focused on optimizing laboratory-based X-ray...

Development and validation of a theoretical test for ultrasound-guided biopsy competence in the head and neck

PURPOSE: This prospective study is designed to test the validity of a multiple-choice question (MCQ) test in assessing theoretical knowledge of ultrasound-guided fine-needle aspiration biosy and core-needle biopsy of the head and neck. METHODS: Seven international experts reached...

Four years on: following the pathway to real world impact of engineering research

Here we present five short case studies in which key authors of papers originally published in Communications Engineering in 2022 describe the impact of their work four years on. These reflections provide a glimpse of what the papers meant for the key researchers involved, their...
