Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)

open access: yesAdvanced Science, EarlyView.
ABSTRACT On‐site monitoring of microorganisms remains challenging because of low concentrations, strong background interference, and dynamic aerosol diffusion, particularly for aerosol‐transmitted pathogens. Here, we report a rapid detection platform that integrates a Puri‐focusing microfluidic chip, electrochemical impedance spectroscopy (EIS), and ...

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

open access: yesAdvanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Transferable Deep Reinforcement Learning With Edge‐Contour‐Depth Fusion for Autonomous Wireless Capsule Endoscopy Navigation

open access: yesAdvanced Science, EarlyView.
This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Stabilization and disturbance rejection for the beam equation [PDF]

open access: yesProceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2001
In this very important paper a linear time-invariant system, which is represented by a one-dimensional Euler-Bernoulli beam equation in a bounded domain, is considered. The beam is clamped at one end, and the boundary control force input is applied at the other end. For the system, a finite-dimensional dynamic boundary controller is proposed.

Drum Water Level Control Based on Improved ADRC

open access: yesAlgorithms, 2019
Drum water level systems show strong disturbance, big inertia, large time delay, and non-linearity characteristics. In order to improve the antidisturbance performance and robustness of the traditional active disturbance rejection controller (ADRC), an ...

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

open access: yesAdvanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

An enhanced anti-disturbance attitude control for the unmanned aerial vehicle subject to multiple disturbances

open access: yesSystems Science & Control Engineering, 2020
In order to further improve the anti-disturbance capability and reduce the conservativeness of unmanned aerial vehicle (UAV) attitude control system, a new enhanced anti-disturbance control law by combining the active disturbance rejection control with ...

Evolving an auto-disturbance-rejection controller for a simulator servo system

open access: yes, 2008
This paper presents an evolutionary controller design method for a flight simulator servo system. The method consists of a population of Auto-Disturbance-Rejection Controller(ARDC) that evolve towards an optimal controller through the use of a genetic ...

Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

open access: yesAdvanced Science, EarlyView.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

Active Disturbance Rejection Control of Permanent Magnet Synchronous Motor Based on RPLESO

open access: yesEnergies
In view of the problem of the low-speed jitter of household lawn mowers driven by a permanent magnet synchronous motor (PMSM) at low speeds and high torque, and the complicated parameters of traditional non-linear active disturbance rejection controllers,
