Active Visual Perception: Opportunities and Challenges

Active visual perception enables an intelligent system to improve perception by controlling how visual evidence is acquired. However, differences in how studies define active perception and evaluate its benefits make approaches difficult to compare across tasks. This review first...

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...

Seismo-ripples

Earthquake prediction has long been considered one of the greatest challenges in the global scientific community due to the complex and uncertain nature of seismogenic processes, along with the prevailing consensus that earthquakes are inherently unpredictable. Here, we present a...

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...

Self-sustaining microbattery fueled by pectin via enzymatic catalysis

Bio-derived self-sustaining microbatteries are promising power sources for implantable and wearable electronics due to their excellent biocompatibility and biodegradability. However, their practical deployment is hindered by limited operational lifetime and low energy density, pr...

Creep Damage Model Considering Viscoplastic Strain Rate and Energy Dissipation

ABSTRACT In the creep process of rocks, energy dissipation is the core driving factor of damage evolution. The initiation and propagation of microcracks within rocks, as well as the closure and penetration of pores, are all accompanied by irreversible energy dissipation, and the...

Robust Ferroelectricity in Chalcogenides Down to 2 nm Particles

ABSTRACT Nano‐ferroelectric materials are essential for advancing miniaturized energy converters, optoelectronics, and nonvolatile memory devices. However, the depolarizing fields of size‐reduced nanoparticles will weaken or even eliminate the ferroelectric spontaneous polarizati...

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...

DGPRT-ResNet: A Difference-Guided and Prototype-Regularized Residual Network with Trend Reconstruction for Small-Sample Hyperspectral Soil Total Nitrogen Prediction

Accurate and rapid estimation of soil total nitrogen (TN) from visible–near-infrared hyperspectral data is important for precision agriculture, but small-sample modeling remains challenging because limited labeled samples often lead to unstable feature representations and insuffi...
