Inference of Microporosity Phase Properties in Heterogeneous Carbonate Rock With Data Assimilation Techniques

Abstract Accurate digital rock modeling of carbonate rocks is limited by the difficulty in acquiring morphological information on small‐scale pore structures (microporosity phases in computed tomography images), which provide crucial connectivity and contribute significant surfac...

Geometric inverse semigroup theory: a note on the Milnor–Schwarz lemma for inverse monoids

Abstract We generalise the Milnor–Schwarz lemma to inverse monoids acting on presheaves of geodesic metric spaces. We provide two proofs of this fact: one only uses elementary techniques, inspired by the arguments for group actions on metric spaces; the other involves a version o...

Normal forms of elliptic automorphic Lie algebras and Landau–Lifshitz type of equations

Abstract We present normal forms of elliptic automorphic Lie algebras with dihedral symmetry of order 4, which arise naturally in the context of Landau–Lifshitz type of equations. These normal forms provide a transparent description and allow a classification of such Lie algebras...

A compilation of global bio-optical in situ data for ocean-colour satellite applications – version four

Abstract. A global in situ dataset for validation of satellite products from the ESA Ocean Colour Climate Change Initiative (OC-CCI) is presented. This version of the compilation, with data starting in 1996, extends to 2025, which is important for the validation of recent algorit...

Tomographic reconstruction of photoelectron elliptical dichroism in chiral terpenes and terpenoids

Velocity-map imaging was combined with a novel tomographic reconstruction algorithm to investigate photoelectron elliptical dichroism (PEELD) in the 400 nm multiphoton ionization of the chiral molecules (+)-fenchone, (+)-α-pinene, and (+)-3-carene. Building on our recent study of...

Harnessing Diversity: Majority‐Group Acculturation Predicts Creativity and Flourishing Over Time

ABSTRACT Creativity and flourishing are core aims of higher education (HE) institutions and government initiatives globally. Large‐scale projects have linked creativity and flourishing with cultural diversity, yet their associations with majority‐group acculturation (i.e., how me...

Fuel use and cost intensity analysis of UK fishing vessels

In fisheries, greenhouse gas accounting has largely focused on fuel use during resource extraction. Beyond its climate impact, fuel use also affects the economic viability of the fishing industry and its capacity to mitigate emissions and adapt to climate change scenarios. Unders...

Compositional Neural-Cyber-Physical System Verification in the Interactive Theorem Prover of Your Choice

Formal verification of neuro-symbolic cyber-physical systems, such as drones, medical devices and robots, is complicated. Neural components must be trained to be optimal with respect to the available data as well as the safety specifications, and then verified using specialised s...

ODARRL: Obstacle- and Disturbance-Aware End-to-End Residual Reinforcement Learning for Underwater Robot Trajectory Tracking with Obstacle Avoidance

ROVs are essential for marine exploration and underwater operations, yet conventional teleoperation relies heavily on skilled human operators, and many autonomous methods stop at high-level planning rather than low-level actuation, limiting robustness in disturbed and cluttered e...

The Global Supply Chain Resilience Paradox as an Ethical Dilemma: Trade‐offs, Tensions, and Multilevel Strategies in Times of Crisis and Disruption

ABSTRACT This research examines the resilience paradox in global supply chains, exploring how trade‐offs between economic and social‐ecological resilience escalate into managerial dilemmas under high environmental uncertainty. Using an abductive theory extension approach, we anal...

Latent dimensions of financial behaviour derived by principal component and factor analysis

Abstract Rather than directly measuring the dimensions of financial behaviour, this study constructs latent dimensions from observed indicators through multivariate analysis. These latent constructs are subsequently aligned with conceptually developed dimensions. Dimensionality r...

Benzo[ c ][1,2,5]Thiadiazole Linkers Enhance the Effectiveness of Cavity‐Containing Supramolecular Photocatalysts

A family of seven novel supramolecular photosensitizers comprising benzo[c][1,2,5]thiadiazole (BTZ) tethered calix[4]arene (C[4]) scaffolds has been synthesized using cross-coupling strategies with selectively halogenated C[4]s, affording target compounds in high yield using faci...

Assessing the chloride-ingress performance of binary and ternary low-clinker concretes through electrical resistivity measurements

With increasing use of high levels of supplementary cementitious materials to reduce clinker content, a comprehensive understanding of hydration and microstructural development within the concrete cover zone is critical to durability and long-term performance. This paper examines...

From undifferentiated to defined: a mixed-methods, data-driven investigation of the acculturation of culturally undifferentiated majority members

Abstract In increasingly diverse societies, people in intercultural contact must navigate cultural diversity to find their place and sense of belonging. Yet, research on acculturation has largely focused on minority groups, leaving majority group responses to cultural change unde...
