A Biofabricated Human Acinus‐on‐a‐Chip Unveils Mechanotransductive Drivers of Ventilator‐Induced Lung Injury via Decoupling Volutrauma and Barotrauma

open access: yesAdvanced Science, EarlyView.
This bioinspired acinus‐on‐a‐chip recapitulates VILI pathology, revealing that volutrauma drives P53/NF‐κB pathways while barotrauma triggers mitochondrial‐Wnt dysregulation. A fibrotic transitional cell cluster was identified. Pharmacological interventions targeting these pathways significantly ameliorated injury, establishing a mechanobiological ...

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

open access: yesAdvanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Decoding Viral Transmission Dynamics in Structured Populations Using a Microfluidic Herd‐Immunity‐on‐a‐Chip Platform

open access: yesAdvanced Science, EarlyView.
A microfluidic Herd‐Immunity‐on‐a‐Chip experimentally recreates structured contact networks to quantify viral transmission dynamics. By controlling susceptible, infected, and non‐susceptible populations, the platform reveals how contact topology governs the reproduction number, outbreak propagation, herd‐immunity–like behavior, and intervention ...

Bridging Horizontal to Vertical Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

T-PdM: a tripartite predictive maintenance framework using machine learning algorithms

open access: yesInternational Journal of Computational Science and Engineering, 2022
The purpose of this paper is to propose new predictive maintenance (PdM) framework that has three aims: 1) estimating the remaining useful life (RUL) of a machine; 2) classifying machine health status (failure/non-failure); 3) discovering the relationship between the errors and component failures of machines by using machine learning (ML) techniques ...

Leveraging Advanced Process Control (APC) technology in developing Predictive Maintenance (PdM) systems

2012 SEMI Advanced Semiconductor Manufacturing Conference, 2012
Predictive Maintenance (PdM) systems use process and equipment state information to predict when a tool or a particular component in a tool might need maintenance. PdM systems can be realized cost-effectively by leveraging Advanced Process Control (APC) technologies and infrastructure.

Effects of predictive maintenance(PdM), Proactive maintenace(PoM) & Preventive maintenance(PM) on minimizing the faults in medical instruments

2013 2nd International Conference on Advances in Biomedical Engineering, 2013
Corrective maintenance (CM) is a big concern for both doctors and medical engineers; it has a direct influence on rising the unplanned downtime for the medical instruments. Our objective is to prove that by implementing a good scheduled maintenance program including Proactive, Predictive and Preventive maintenance will decrease the high cost in time ...

PdM

Proceedings of the Tenth International Symposium on Information and Communication Technology - SoICT 2019, 2019
In the current manufacturing world, maintenance has a critical role to play in improving companies' competitiveness. Among the available maintenance strategies, predictive maintenance seems to be the most promising because failures are predicted and a timely reaction is possible.
