Baseline direction measurement for active optical imaging systems

We propose a closed-form method for measuring the baseline direction in active optical imaging systems, including projector-camera and laser-emitter imaging configurations. The method uses two planar homographies induced by observing a planar target at different system-to-plane d...

Tailoring configurational entropy and phase evolution in (La 0.2 Ce 0.2 Nd 0.2 Sm 0.2 Eu 0.2 ) 1 – x Bi x VO 4 ceramics for high-performance C-band dielectric resonator antennas

Abstract Achieving a near-zero temperature coefficient of resonant frequency (τf) while maintaining an ultra-high quality factor (Q×f) remains a critical challenge for microwave dielectric ceramics in next-generation 5G/6G communication systems. Herein, we report a configurationa...

A buckling stagnant slab observed inside the mantle transition zone

Subducting lithosphere is a primary driver of plate tectonics. Seismic tomography shows that some slabs are stagnant in the mantle transition zone (MTZ), and it is debated why they do not continue directly across the MTZ base ( d 660). Here we demonstrate by seismic Receiver Func...

Artificial Intelligence-Driven Real-Time Restoration of a Cultural Heritage Analog Digital Twin Model

The preservation of cultural heritage structures is increasingly challenged by environmental degradation, aging, and human activities. This study presents an artificial intelligence (AI)-driven framework for real-time monitoring, crack detection, and restoration planning within a...

From Destruction to Reconstruction: Substrate-Driven Biosynthesis of Antioxidants from Antibiotic Residues in Hyperthermophilic Composting

Abstract The accumulation of tetracycline (TC) in organic fertilizers poses severe risks by fostering antibiotic resistance in soil ecosystems. Hyperthermophilic composting effectively mitigates these threats, achieving nearly complete TC removal via thermal selection. Although p...

Enhancing bending load prediction of CaCO₃-filled polypropylene composites via data augmentation and ensemble machine learning

Abstract Predicting the mechanical properties of calcium carbonate (CaCO₃)-filled polypropylene (PP) composites is crucial for their industrial applications. However, conventional experiments are costly and time-consuming, resulting in limited data and challenges for accurate mod...

Four-Phonon Scattering and Phonon Coherence in Monolayer Penta-CdO2 with Ultralow Lattice Thermal Conductivity

Abstract Two-dimensional (2D) pentagonal materials have emerged as promising candidates for low-lattice-thermal-conductivity applications owing to their extraordinary geometry structures and strong intrinsic anharmonicity. However, the roles of high-order phonon scattering and ph...

Effect of Semisolid Casting and Rapid Solidification Processes on Microstructure and Damping Behavior of A356 Aluminum Alloy

This research seeks to enhance the vibration‐damping and noise‐suppression performance of automobiles, while also increasing the damping capacity of A356 aluminum alloys employed in vehicle components. Accordingly, A356 aluminum alloys were prepared via semisolid casting combined...

From Molecular Designs to Nanomaterials for Electrochemical PFAS Detection: A Review

Abstract The pervasive occurrence of per- and polyfluoroalkyl substances (PFAS) and the implementation of stringent regulatory guidelines necessitate rapid, highly sensitive analytical methodologies. Although liquid chromatography-tandem mass spectrometry (LC-MS/MS) remains the g...

Synergistic Water‐State Regulation and Network Densification Enable Low‐Loss Fine‐Core Hydrogel Flexible Optical Fibers for Wearable Soft Photonics

ABSTRACT Biological soft photonics shows broad potential in wearable health monitoring. Hydrogel flexible optical fibers (HFOFs) possess significant application potential due to biocompatibility. However, while high water content and multi‐network architectures endow HFOFs with u...

DeCyReM: De-Cycled Residual Memory with Utility-Gated Retrieval for Traffic Flow Forecasting

Accurate traffic-flow forecasting remains challenged by abrupt and irregular states even after dominant periodic patterns are captured. Existing predictors model the resulting difficult errors implicitly through their parameters and cannot explicitly reuse specific historical err...

MURECAST: Memory-Based Utility-Aligned Residual Evidence with Calibrated Activation for Selective Correction of Traffic-Flow Forecasts

Short-term traffic-flow forecasting predicts road-network states, yet spatio-temporal predictors can leave structured, context-dependent residuals. They are seldom reused at inference, while similarity-based transfer can introduce corrections that increase error. We propose Memor...

Copper-Catalyzed Desymmetrization toward Planar Chiral Disubstituted [2.2]Paracyclophanes: A Route to Solid-State CPL Materials

Abstract Enantiomerically enriched [2.2]paracyclophanes (PCPs), particularly those bearing two functional groups on distinct decks, constitute privileged scaffolds for circularly polarized luminescence (CPL) materials owing to their inherent stable planar chirality and unique opt...
