Ala viridis sublimis : on butterflies, budgies and bicontinuous greens

Abstract Green structural colour associated with bicontinuous photonic nano structures occurs in both butterflies (Lycaenidae, Papilionidae) and birds (Chloropseidae leafbirds, Psittaculidae parrots). In butterflies and leafbirds, porous chitin or keratin single gyroids reflect g...

Steric stabilizers inhibit or enhance enzymatic digestion depending on the internal nanostructure of lipid nanoparticles

Abstract Lipidic nanoparticles (LNPs), including liposomes and cubosomes, are widely employed drug delivery systems owing to their biocompatibility and capacity for stimuli-responsive ‘smart’ drug release. Steric stabilizers, including DSPE-PEG-2000 and Pluronic F127, are commonl...

Hyperbolic confinement: self-assembly of asymmetric diblock co-polymers on triply periodic minimal surfaces

Abstract We investigate the self-assembly of compositionally asymmetric AB diblock co-polymers confined to thin hyperbolic films on the three cubic minimal surfaces: the primitive, the diamond and the gyroid. To analyse and quantify the assemblies, we use a computational pipeline...

High symmetry embeddings of rectilinear tangles

Abstract Finite tangles are embeddings of graphs that include knots or links as subcomponents. We describe vertex-transitive tangles with 12 or fewer crossings, as well as tangles with just two crossings that feature the Hopf link. Additionally, we consider tangles formed by addi...

Popular crossings: Lin Chen and his bifurcated editorial practice in 1950s Singapore and Malaya

This article reframes the Singapore Chinese dramatist Lin Chen’s cultural practice by explicating discrepant modes of popular cultural production and circulation in 1950s Singapore and Malaya through commercial printing. Today, Lin Chen (1919–2004) is remembered primarily as the...

Mapping structural heterogeneity in three-dimensional biophotonic gyroid networks using position-resolved small-angle X-ray scattering

Abstract The wings of select Papilionid and Lycaenid butterflies contain a three-dimensional gyroid network of a solid cuticle phase in air. In butterfly scales, gyroid networks are optically interesting, as they create the green colour observed in the wings of these butterflies....

Three-colour pride—geometry and topological transformations in self-assembly models of three-arm star molecules

Abstract Polyphilic three-arm star-shaped molecules self-assemble in a wide variety of morphologies. We present an analysis of the geometry of the possible mesophases formed by three-star molecules with mutually immiscible arms. The structures resulting from such molecular self-a...

Association Between Efficacy and Pharmacokinetics of DMB-3115 and its Originator Ustekinumab in Patients with Chronic Plaque Psoriasis: An Exposure–Response Analysis

DMB-3115 is a biosimilar to ustekinumab (Stelara ® ). Although a single-dose study conducted in Europe showed that the pharmacokinetics of DMB-3115 was equivalent to that of ustekinumab, another single-dose study in Japan suggested that the maximum serum concentration ( C max ) o...

Impacts of the three-dimensional radiative effects on cloud droplet number concentration retrieval and regression-based albedo susceptibility estimates

Abstract. Cloud droplet number concentration (Nd) in warm liquid clouds plays a crucial role in understanding cloud microphysical processes and the influence of aerosol–cloud interactions (ACI) on Earth's climate. Nd from satellite-retrieved cloud properties such as the cloud opt...

Potent type-specific de novo antibodies complement broadly reactive imprinted antibodies in immune responses to SARS-CoV-2 variants

Abstract For rapidly mutating viruses such as influenza viruses and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), immune memory recalled by antigenically drifted variants primarily comprises antibodies that cross-react to the priming strain rather than de novo eli...

Twenty years of the EPINET database

Abstract The EPINET project (Euclidean Patterns In Non-Euclidean Tilings) catalogues crystalline frameworks (three-periodic nets) generated from tilings of triply periodic minimal surfaces. These nets have a broad distribution of structural motifs that are of potential interest t...

Interpreting exploratory immune signals and parent‐reported outcomes after labour epidural analgesia

The prospective BASIC/U-BIRTH analysis by Asif et al. followed 1962 mother–child dyads and showed that the crude 18-month Child Behaviour Checklist differences associated with labour epidural analgesia were not sustained after confounder adjustment or at 6- and 11-year follow-up...

The chiral gyrating H’-T surface family: construction from the dual qtz – qzd nets and existence proof using a toroidal Weierstrass method

Abstract This paper provides an existence proof for a one-parameter family of chiral unbalanced triply periodic minimal surfaces of genus four. We name these gyrating H’-T surfaces because they are related to Schoen’s H’-T surfaces in a similar way as the gyroid is to the primiti...

Hexagulation numbers: symmetry breaking on the gyroid surface

Abstract The regular arrangements of identical spheres on the gyroid surface have been investigated using Monte Carlo simulations of hard spheres undergoing the Alder transition. In our preceding study, we showed that these regular structures on saddle-shaped triply periodic mini...

Formation of a silica scaffold with a hyperbolic surface structure as a time-frozen glimpse by ultraviolet curing

Abstract Triply periodic hyperbolic surfaces have been extensively investigated in various natural and artificial self-assembled systems and have attracted great attention because of their complexity and geometrical beauty. However, understanding their formation during bottom-up...

Sugammadex and postoperative pulmonary complications after upper gastrointestinal endoscopy

Tsai et al. report that sugammadex use was associated with fewer postoperative pulmonary complications than neostigmine following upper gastrointestinal endoscopy [1]. These findings contribute to the growing body of evidence supporting the respiratory benefits of sugammadex comp...

Gravity Wave Energy Baselines (∼30–110 km) Established From Lidar Observations at McMurdo (77.84°S, 166.67°E), Antarctica: Energy Dissipation and Constituent Diffusion

Abstract Lidar observations above McMurdo, Antarctica from 2011 to 2024 are used to characterize gravity wave (GWs) potential energies () in the mesosphere and lower thermosphere (MLT). Alongside characterizations in the middle atmosphere (30–70 km), the GW baselines show dissipa...

Trace Elements in Total Atmospheric Deposition Directly Measured Over the Caribbean Region: Natural Versus Anthropogenic Sources and Geographic Origin

Abstract Dust, sea salt, and anthropogenic and biogenic particles in total atmospheric deposition are sources of essential elements that can significantly impact biogeochemical cycles in the Atlantic Ocean and in islands of the Caribbean region. This unique 41‐month data set reco...

Structure and Dynamicsof the HIV-1 EnvelopeProtein on the Virion Envelope

HIV-1 buds from infected cells as immature virion particles with a scattered envelope glycoprotein (Env) distribution on their envelope. It then undergoes maturation, during which the viral protease cleaves the Gag polyprotein at multiple sites, leading to structural reorganizati...

Morphological and Size‐Dependent Enrichment of Endotoxins in Coastal Spray Aerosols: Implications for Regional Respiratory Health Risks

Abstract Sea spray aerosols (SSA) transport bioactive substances that affect the Earth's environmental and climate system. We investigated the enrichment of endotoxins (LPS), characterized their influence on the SSA morphologies, and evaluated the respiratory tract deposition. LP...
