Infusible Extracellular Matrix Biomaterial Enhances Cell‐Specific Pro‐Repair Responses Following Acute Myocardial Infarction

open access: yesAdvanced Healthcare Materials, EarlyView.
We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...

Chance constraint based risk-aware optimal power flow for cascading failure prevention

open access: yes, 2016
Once part or whole of the power system is exposed to some dangerous situations, e.g., malicious terrorist attacks or extreme weather conditions, the potential cascading failure is a severe threat to the power system.

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

A Branching Process Approximation to Cascading Load-Dependent System Failure

open access: yes, 2004
Networked infrastructures operated under highly loaded conditions are vulnerable to catastrophic cascading failures. For example, electric power transmission systems must be designed and operated to reduce the risk of widespread blackouts caused by ...

A Long‐Lived Human Neurovascular PENTA Culture Model Captures Incomplete Vascular Repair and Glia‐Associated Signaling After Traumatic Brain Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
A long‐lived, five‐cell‐type human neurovascular (PENTA) model recreates vascular disorganization and incomplete repair after traumatic brain injury (TBI). By integrating endothelial, glial, neuronal, and immune components within a 3D scaffold, the platform enables time‐resolved analysis of neurovascular remodeling and provides a human‐relevant system ...

Estimating failure propagation in models of cascading blackouts

open access: yes, 2005
— We compare and test statistical estimates of failure propagation in data from versions of a probabilistic model of loading-dependent cascading failure and a power systems blackout model of cascading transmission line overloads.

Criticality in a cascading failure blackout model

open access: yes, 2006
We verify and examine criticality in a 1000 bus network with an AC blackout model that represents many of the interactions that occur in cascading failure.

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

Identification of Cascading Failure Propagation Under Extreme Weather Conditions [PDF]

open access: yes, 2018
As a fundamental infrastructure, power systems play a vital role in modern society, but it can be damaged by different adverse events e.g. natural, accidental, and malicious, of which the adverse natural events, especially extreme weathers, with huge ...

Mitigating Multi-Stage Cascading Failure by Reinforcement Learning

open access: yes, 2019
This paper proposes a cascading failure mitigation strategy based on Reinforcement Learning (RL) method. Firstly, the principles of RL are introduced. Then, the Multi-Stage Cascading Failure (MSCF) problem is presented and its challenges are investigated.
