Surface Elasticity Based Nonlocal Vibration Analysis of Bidirectional Functionally Graded Tapered Nanobeam

open access: yesAdvanced Theory and Simulations, EarlyView.
This work proposes a surface elasticity‐based nonlocal model for analyzing the vibrations of bi‐directionally graded tapered nanobeam. The results demonstrate that, in absence of surface effect, the increasing value of tapered parameter leads to stiffness‐hardening of the nanobeam. However, the consideration of surface effect changes this trend and the

Accurate and Efficient Behavioral Modeling of GaN HEMTs Using An Optimized Light Gradient Boosting Machine

open access: yesAdvanced Theory and Simulations, EarlyView.
Machine Learning (ML) and optimization have permeated almost every aspect of engineering applications. Recent years have seen great traction toward ML‐based GaN HEMT modelling. However, ML‐based GaN HEMT models are mostly developed using variants of Artificial Neural Network (ANN).

Substrate‐Restricted Asymmetric Evolution of Solid‐State Nanopores

open access: yesAdvanced Theory and Simulations, EarlyView.
Standalone nanopores can either expand or shrink based on the nucleation mechanism. A substrate‐restricted asymmetric pore dynamics are uncovered ‐ top expansion and bottom shrinkage, with minimum aperture reduced and forming a conical geometry, driven by molecular migration along an energy potential gradient within nanopores.

Nanoplasmonic Infrared Microarray Sensor Enabling Structural Protein Biomarker‐Based Drug Screening for Neurodegenerative Diseases

open access: yesAdvanced Science, EarlyView.
This work introduces an on‐chip, integrated plasmonic infrared microarray sensor that enables high‐throughput, label‐free drug screening targeting structural protein biomarkers in neurodegenerative diseases. Through ultra‐compact microwell arrays, the sensor achieves ultra‐sensitive, rapid, and multiplexed secondary structural analysis of the effect of

Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

open access: yesAdvanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...
