Field‐Cycling NMR Relaxometry in Tire Elastomer Science

Magnetic Resonance in Chemistry, EarlyView.
Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

Polymaterial Lattice Discrete Particle Model for the Optimization of Lightweight Aggregate Concrete: Intragranular Fracture and Compression Behavior

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.

Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

Journal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).

Optoelectronics of Single Mixed Dislocations in Van Der Waals Core‐Shell Nanowires

Small, EarlyView.
Ge1‐xSnxS van der Waals core‐shell nanowires can host single helical dislocations whose character is tunable from a pure screw to a majority edge dislocation via the core‐shell lattice mismatch. Cathodoluminescence shows profound effects once an edge component is introduced, notably a lowering of the spontaneous emission quantum efficiency due to the ...

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures

Structural Concrete, EarlyView.
Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

High Throughput Discovery of Grotthuss‐Type Lithium‐Ion Transport Mechanism in Metallosalen Covalent Organic Frameworks

Transformative Chemistry, EarlyView.
Through a high‐throughput simulation of 3141 COF/lithium salt systems, we reveal that reducing framework weight universally enhances ionic conductivity. Key to performance is the matching of pore chemistry with specific anions; notably, we discover an anion‐driven “shuttle” cooperative transport mechanism, which proposes new principles for designing ...

Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

A Quantised Push‐Sum Distributed Adaptive Momentum Algorithm for Optimisation Over Directed Networks

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT In this paper, we investigate a distributed constrained optimisation problem over directed networks. The agents in the networks conduct local computations and communications, endeavouring to collaboratively minimise the aggregation of all locally known convex cost functions subject to a global constraint set.

ANPGT: Towards Adaptive Node Property Extraction and Integration

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Graph transformers (GTs) with elaborate positional/structural encodings (PEs/SEs) have excelled in graph representation learning, especially in graph‐level tasks. However, their potential in large‐scale node classification remains untapped for several reasons: (i) Current PEs/SEs are insufficient in modelling large‐scale real‐world graphs ...

Boosting Embodied Visual Localisation Through Multi‐Granular Semantics and Multi‐Robot Consensus

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Achieving high accuracy and synergy remains extremely difficult for multi‐robot embodied visual localisation, which suffers from persistent real‐world challenges such as viewpoint ambiguity, appearance variation and dynamic occlusion. Conventional optimisation‐based methods often lead to incorrect feature matching without domain adaptation ...
