Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

The Frequency‐Domain Lattice Boltzmann Method (FreqD‐LBM): A Versatile Tool to Predict the QCM Response Induced by Structured Samples

open access: yesAdvanced Theory and Simulations, EarlyView.
FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

Materials Selection Principles for Designing Electro‐Thermal Neurons

open access: yesAdvanced Electronic Materials, EarlyView.
Materials property – performance relations are established for new and old electrical materials leveraged as electro‐thermal oscillators emulating neuron dynamics. Robust, reconfigurable, high frequency, low power characteristics are explicitly tied to highly nonlinear electrical transport, small specific heat, and greater electrical than thermal ...

Electrically‐Driven Metal‐Insulator Transitions Emerging from Localizing Current Density and Temperature

open access: yesAdvanced Electronic Materials, EarlyView.
Negative differential resistance (NDR) is a key electronic response enabling two‐terminal artificial neurons. Interactions between electro‐thermal localizations and metal–insulator transitions (MITs) are investigated in a 3D multiphysics simulation of a lateral device. These findings demonstrate that the MIT nucleates in regions of high current density,

Aspect-Level Sentiment Analysis Based on Syntax-Aware and Graph Convolutional Networks

open access: yesApplied Sciences
Aspect-level sentiment analysis is a task of identifying and understanding the sentiment polarity of specific aspects of a sentence. In recent years, significant progress has been made in aspect-level sentiment analysis models based on graph ...

Electronic Nanomaterials for Plants: A Review on Current Advances and Future Prospects

open access: yesAdvanced Electronic Materials, EarlyView.
Global food security faces mounting challenges from climate change and rapid population growth. This review highlights the pivotal role of electronic nanomaterials–including metals, metal oxides, and carbon‐based structures–in enhancing plant photosynthesis, nutrient uptake, and stress resilience. Furthermore, it explores how emerging platforms such as

Programmable Cryogenic Memory in a Ge/GeSi Heterostructure

open access: yesAdvanced Electronic Materials, EarlyView.
A highly programmable memory function that occurs due to a charge tunneling and trapping mechanism is demonstrated in a Ge/GeSi heterostructure field‐effect thransistor. Over three orders‐of‐magnitude control over the conductance state of the device is achieved using either the device SET or the device RESET process, suggesting potential for ...
