Bridging Element and System Scales: A Scale-Based Critical Review of Numerical Modelling for Dynamic Ground Support in Deep Hard-Rock Mines

This critical review of 92 numerical modelling studies on dynamic ground support in deep hard-rock mines identifies a fundamental gap in fully coupled rock mass–support system simulations and proposes a physics-informed, microseismic-calibrated framework to bridge the disconnect between rock-mass demand and support response for future mechanism-based design.

Beyond Appearance: Transient Vision for Homogenised Milk Purity

This paper demonstrates the feasibility of using non-spectral, direct time-of-flight SPAD sensing to detect adulteration and degradation in homogenised milk through sealed packaging by analyzing transient photon-arrival histograms, achieving high accuracy in multi-class screening and binary discrimination even when visual cues fail.

Engineering Paediatric Formulations: A Systematic Review of Process Systems Methods, Sectoral Gaps, and the PPES Framework

This systematic review reveals that while process systems engineering methods are well-established in adult pharmaceuticals, their application to paediatric formulations remains heavily skewed toward drugs and neonates, with significant gaps in food, cosmetic, and hygiene products as well as older age groups, prompting the authors to propose the Paediatric Product Engineering Systems (PPES) framework to guide future development.

A State-Space Framework for Redefining Failure Onset in Unsaturated Soils: The Role of Pore-Air Exhaust Conditions and Trajectory Directional Coherence

This study proposes a novel, model-independent framework for detecting failure onset in unsaturated soils by identifying a critical suction threshold of 30 kPa that governs the stability of pore-air exhaust conditions and defining failure as a regime shift in stress trajectory directional coherence rather than a discrete stress-point threshold.

Cyclic Shear Response of Polyurea-Strengthened Dry-Joint Stone Masonry Walls

This study validates through finite element micro-modeling that polyurea coatings significantly enhance the cyclic shear performance, energy dissipation, and residual displacement characteristics of dry-joint stone masonry walls, establishing them as an effective seismic retrofitting solution.

Reinforced Platinum Silicone Composites for Durable Cervical Dilation Simulation in Obstetric Training

This study demonstrates that platinum-cured silicone reinforced with a double-layer configuration of Gauze Family 1 creates a durable, high-fidelity synthetic tissue capable of withstanding repeated cervical dilation simulations while accurately mimicking the mechanical properties of the human cervix.

Counterfactual Interventional Reliability of Pulse Arrival Time in Wearable ECG-PPG-IMU Systems Under Structured Motion Artifacts

This study introduces Counterfactual Interventional Reliability (CIR), a novel metric that outperforms existing baselines in identifying unsafe Pulse Arrival Time estimates under structured motion artifacts by distinguishing inference-specific stability from generic waveform quality in wearable ECG-PPG-IMU systems.

Why Deterministic AI Weather Models Fail at Extremes and Physical Conservation: From the Perspective of Probabilistic Mean Field

This paper argues that deterministic AI weather models fail to capture extremes and conserve physical laws because minimizing mean-square error forces them to predict conditional means rather than full transition distributions, a limitation that probabilistic generative approaches can overcome by better representing intrinsic atmospheric variability.
