Temporal max pooling for robust multi-class fault diagnosis of PMSM-based drive modules at unseen sensor locations

Abstract In vibration-based fault diagnosis of permanent magnet synchronous motor (PMSM) drive modules, sensor relocation can induce distribution shifts that degrade classification performance and increase diagnostic errors. This study evaluates whether a lightweight diagnostic m...

Experimental study on inhibition mechanism of composite inhibitors for coal spontaneous combustion at critical temperature

To elucidate the inhibition mechanism of composite inhibitors during coal spontaneous combustion under a selected critical-temperature condition, three coals with different ranks were investigated. Temperature-programmed oxidation coupled with gas chromatography, in-situ Fourier...

Multi-Step Obstruction Reasoning for Target-Oriented Grasp Sequence Generation in Cluttered Scenes

Retrieving target objects in severe clutter requires multi-step reasoning to establish valid obstacle removal sequences. While recent Vision–Language Models (VLMs) have advanced instruction-driven clutter grasping, existing paradigms lack explicit construction of graph-constraine...

Shape-Controlled Poly(N-isopropylacrylamide) Actuators Enabled by Tensile-Stress Mismatch for Temperature-Adaptive Textiles

Thermal comfort is a key determinant of human health and requires adaptive responses to dynamic environments. Here, we report a temperature-adaptive textile enabled by a tensile stress mismatch-driven poly(N-isopropylacrylamide) (PNIPAM) actuator operating within a human-friendly...

Scalable retinal projection augmented reality displays with confocal dual-ellipsoidal combiner

Abstract Compact near-eye displays (NEDs) with large visual scope, high resolution, and high optical efficiency are essential for advanced augmented reality (AR) applications. However, existing AR NED architectures suffer from inherent trade-offs among these metrics, restricting...

On-demand inverse design of metamaterials via denoising diffusion probabilistic models

Abstract The nonlinear and non-unique relationship between unit-cell topology and bandgap properties motivates the development of complementary data-driven approaches for metamaterial inverse design. This work presents a conditional denoising diffusion probabilistic model (DDPM)-...

Ultrahigh Polarization Sensitivity via Bias‐Modulable Twisted Heterojunction Photodetectors With AoLP Detection and Polarity Reversal

ABSTRACT Polarization‐sensitive photodetection provides a critical degree of freedom for multidimensional optical information processing; however, achieving both high polarization selectivity and direct extraction of the angle of linear polarization (AoLP) within a single compact...

MOF‐Derived Cu‐TiO 2 /Alginate Micromotors for Buoyancy‐Regulated 3D Motion

ABSTRACT Micro‐ and nanomotors (MNMs) promise impact in the areas of environmental remediation and biomedicine, but reliable three‐dimensional (3D) control remains challenging. Conventional bubble‐propelled MNMs can move in 3D, yet their trajectories are stochastic and energy‐ine...

Multi-Bin Batching for Increasing LLM Inference Throughput

As large language models (LLMs) grow in popularity for their diverse capabilities, improving the efficiency of their inference systems has become increasingly critical. Batching LLM requests is a critical step in scheduling the inference jobs on servers (e.g. GPUs), enabling the...

Structure‐Engineered Nanoporous Vanadium Oxide Memristors for Reconfigurable Synapse–Neuron Integration and Synergistic Robotic Motion

ABSTRACT Neuromorphic sensory‐to‐motor interfaces require compact devices that can combine nonvolatile synaptic weight storage with volatile neuronal firing, yet these functions typically rely on distinct material and circuit mechanisms. Here, we report a structure‐engineered VO...

Magnetoelectric BaTiO 3 /CoFe 2 O 4 Thin‐Film Meshes for Neuronal Differentiation

ABSTRACT Magnetoelectric composites offer a powerful route for remotely converting magnetic stimuli into local electrical cues, with promising biomedical applications in electrical stimulation. In strain‐mediated magnetoelectric heterostructures, however, efficient coupling depen...
