Insects select flight speeds that coincide with low metabolic energy expenditure

Abstract Aerodynamic theory predicts a U-shaped relationship between mechanical power and airspeed. Empirical data from birds and bats support a similar U-shaped metabolic power–speed curve, reflecting the underlying muscle mechanics. However, data on insects’ flight energetics r...

Musical Legacies, Memorials and Elegies: Commemorating William Sterndale Bennett

he wears a truer crown Than any wreath that man can weave him. Speak no more of his renown, Lay your earthly fancies down, And in the vast cathedral leave him, God accept him, Christ receive him! 1

A Data‐Driven Approach to the Issue of ‘Catching Up With Monolinguals’

BACKGROUND: Multilingual children in monolingual education systems are generally assessed against monolingual norms, raising questions about identifying genuine language support needs versus expected developmental trajectories. AIMS: This study aimed to identify: (1) the amount o...

Shape modes of $$\mathbb {C}P^1$$ vortices

Abstract In this paper, we investigate the existence of internal modes of vortices in the gauged $$\mathbb {C}P^1$$ C P 1 sigma model. We develop a clean geometric formalism that highlights the symmetries of the Jacobi operator, obtained from the second variation of the energy fu...

Universal Prediction of Molecular Weight Distribution for Entangled Linear Polymers from Linear Rheology Using Neural Networks

Abstract We present a machine learning methodology for inferring the molecular weight distribution (MWD) of arbitrary polydisperse entangled linear polymers from their linear rheology. Using a state-of-the-art tube model, we generate large synthetic rheology datasets to train neu...

Circular design strategies in the post-consumption journey: a systematic literature review of service design for circular fashion SMEs

Purpose Post-consumption processes are increasingly acknowledged as a critical component of facilitating circular fashion systems within small and medium-sized enterprises (SMEs). Nonetheless, research in this area often remains fragmented and dispersed across disciplinary domain...

Immunomodulatory Effects of Galleria mellonella and Alphitobius diaperinus Protein Digestates Generated Using a Modified INFOGEST Protocol – In Vitro and In Silico Evidence

Abstract Insect-derived peptides have attracted increasing attention due to their potential health-promoting properties. This study investigated peptides released from Galleria mellonella (W) and Alphitobius diaperinus (B) proteins following a modified static INFOGEST protocol. D...

ACTIVATE: A protocol for a randomised controlled evaluation of Thumos: A cognitive-behavioural intervention for medical students

Background Medical students experience high rates of burnout and mental health distress, with approximately half reporting burnout, one-third experiencing depression, and one-tenth having suicidal thoughts. These issues are exacerbated during clinical placements and contribute to...

Complex interactions among invasive fishes and flow barriers combine to maintain an endangered native species

Abstract The Breede River in the Western Cape Province is one of South Africa’s major freshwater systems and of high ecological and socio-economic value. Similar to other freshwater systems worldwide, it is threatened by environmental degradation and multiple invasive species. Un...

The plasticisation model of dye diffusion: Part 10

Abstract The Flory–Fox and Gordon–Taylor models were used to predict the extent to which sorbed water reduces the glass transition temperature of poly(ethylene terephthalate) yarn as a function of moisture regain. The extent of water‐induced plasticisation predicted by the Flory–...

Entropic Phase Separation in Polymer–Vitrimer Melts

Abstract Traditional plastics demand a choice between durability (thermosets) and reprocessability (thermoplastics). Vitrimers are a recent class of polymer network combining both of these qualities. Their increased cost of production can be offset by mixing them with a tradition...

Amphipods associate with epibiotic filamentous bacteria at a shallow-water hydrothermal vent

In the deep ocean, hydrothermal vents sustain remarkable animal-microbial symbioses, in which bacteria colonizing animal external or internal tissues use reduced chemicals from venting fluids to perform chemosynthesis and nourish their host. Hydrothermal vents also occasionally o...

Populism and impatience

Abstract We develop a model where highly impatient voters are more likely than others to be subject to institutional frictions in the form of binding borrowing constraints. As impatient, borrowing-constrained voters cannot move long-term policy gains to the present, they turn to...

Quantum many-body mixed phase space revealed by hybrid feedback control

Abstract Understanding how complex systems transition between order and chaos is a central challenge of non-equilibrium physics. Although weak perturbations of classical integrable systems give rise to a mixed phase space in which regular and chaotic trajectories coexist, analogo...

Did “might” make right? Epistemic modals in practical reasoning

Abstract Many philosophers have argued that the orthodox analysis of epistemic-modal sentences, on which such sentences assert facts about what is compatible with some contextually given informational state, is fatally flawed. As an alternative, some have suggested a nonfactualis...

The Generalised Energy Identity and Length of Necks for $$\varepsilon $$-Harmonic Maps

Abstract In this paper we find analogues for $$\varepsilon $$ ε -harmonic maps to the generalised energy identity and the existence of geodesic necks result discovered by Yuxiang Li and Youde Wang for $$\alpha $$ α -harmonic maps. In particular there exist specific quantities dep...

An online approach for integrated railway schedule replanning and passenger reassignment with unknown passenger reactions under hub disruptions

Major railway disruptions, such as city-wide disasters, in hub areas often persist for a long time and affect multiple routes simultaneously. Original railway schedules, including line plans, timetables, and rolling stock dispatching, become invalid and require strategic replanni...

Posterior inference of attitude-behaviour relationships using latent class choice models

The link between attitudes and behaviour has been a key topic in choice modelling for two decades, with the widespread application of ever more complex hybrid choice models. This paper proposes a pragmatic and computationally tractable alternative framework for empirically examin...

Transitivity of mutation of τ‐exceptional sequences in the τ‐tilting finite case

Abstract We prove that mutation of complete ‐exceptional sequences is transitive for ‐tilting finite algebras.

Economic and health impact of integrating smoking cessation services into NHS cancer care pathways in England: a modelling study

Background Research has shown that smoking post-diagnosis negatively impacts cancer outcomes. This study aimed to assess the health and cost impacts of introducing smoking cessation services at cancer diagnosis for people who smoke. Methods A cost-effectiveness model was develope...
