Artificial Piezoelectric Interface Enables Ultrafast Interfacial Ion Kinetic for Highly‐Sensitive Piezoionic Sensors

open access: yesAdvanced Science, EarlyView.
This study proposes a piezoelectric interface modification strategy to amplify the piezoionic effect. The piezoelectric interface generates an intrinsic electric field, which not only drives rapid ion migration but also concentrates polarized ions on the interface. The flexible sensor delivers superior performance, such as a quick response rate, strong

Soft Real-Time Asynchronous Online Learning from Input–Output Data for UAV Model Reference Control Under Uncertain Dynamics and Faulty Actuation

open access: yesDrones
An online off-policy asynchronous real-time model reference tracking control (OOART-MRTC) algorithm is proposed and validated for unmanned aerial vehicles (UAVs) characterized by faulty actuation and parametric uncertainty. The optimal control problem is

Nonverbal Communication in Text-Based, Asynchronous Online Education

open access: yesInternational Review of Research in Open and Distributed Learning, 2019
Does nonverbal communication exist in asynchronous, text-based online education? It is commonly believed that it does not due to the absence of body language and paralanguage.

Asynchronous Cellular Automata [PDF]

open access: yes, 2018
This text is intended as an introduction to the topic of asynchronous cellular automata. We start from the simple example of the Game of Life and examine what happens to this model when it is made asynchronous (Sec. 1). We then formulate our definitions and objectives to give a mathematical description of our topic (Sec. 2). Our journey starts with the

Decoding Structure‐Property Relationships in Anion Exchange Membranes via a Chemically Informed Dual‐Channel Graph Attention Network

open access: yesAdvanced Science, EarlyView.
SPARK decodes structure‐property relationships in anion exchange membranes (AEMs) via a chemically informed dual‐channel graph attention network (DEGAT) that explicitly captures microphase separation. It outputs five‐level grades for hydroxide conductivity and alkaline stability and highlights relevant key structural units, enabling robust pre ...

open access: yesNauka ta progres transportu, 2009
Negative aspects of traditional production-and-conveyer lines for wagon repair are shown. Advantages of a new type of wagon-repair flow – asynchronous flexible one – are considered.

Liver Kinase B1 in CD11c+ Cells Inhibits Fibrosis in Chronic Pancreatitis via the Oncostatin M Signaling

open access: yesAdvanced Science, EarlyView.
This study demonstrates significantly reduced Lkb1 expression in CD11c+ cells in chronic pancreatitis (CP) patients and animal models. Lkb1 deletion enhances CD11c+CD206+ macrophage infiltration and reprograms pancreatic stellate cells (PSCs) via OSM signaling.
