Porphyromonas gingivalis GroEL exacerbates orthotopic allograft transplantation vasculopathy via impairment of endothelial cell function

Molecular Oral Microbiology, EarlyView.
Abstract Orthotopic allograft transplantation (OAT) is a significant approach to addressing organ failure. However, persistent immune responses to the allograft affect chronic rejection, which induces OAT vasculopathy (OATV) and organ failure. Porphyromonas gingivalis can infiltrate remote organs via the bloodstream, thereby intensifying the severity ...

Deep Deterministic Policy Gradient (DDPG) Agent-Based Sliding Mode Control for Quadrotor Attitudes

Drones
A novel reinforcement deep learning deterministic policy gradient agent-based sliding mode control (DDPG-SMC) approach is proposed to suppress the chattering phenomenon in attitude control for quadrotors, in the presence of external disturbances.

Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

Molecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

Hybrid fuzzy and sliding-mode control for motorised tether spin-up when coupled with axial vibration [PDF]

, 2009
A hybrid fuzzy sliding mode controller is applied to the control of motorised tether spin-up coupled with an axial oscillation phenomenon. A six degree of freedom dynamic model of a motorised momentum exchange tether is used as a basis for interplanetary

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

High-order sliding mode control of a DC motor drive via a switched controlled multi-cellular converter [PDF]

, 2011
In this article, we present a high-order sliding mode controller of a DC motor drive connected to a multi-cellular converter. More specifically, we design a second-order (super-twisting) control algorithm for the speed regulation of a DC motor. For this,

Preeclampsia‐derived small extracellular vesicles disrupt blood–brain barrier integrity and activate glial cells in vitro

The Journal of Physiology, EarlyView.
Abstract figure legend This study assessed the impact of plasma‐derived small extracellular vesicles (sEVs) from healthy pregnant women and those diagnosed with late‐onset preeclampsia (PE) on the blood–brain barrier (BBB) integrity and glial cell response. PE patients had higher sEV concentrations than healthy controls.

Surrogate‐Assisted Nonlinear Model Predictive Control for a Lambda Robot

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT This work presents a nonlinear model predictive control (NMPC) framework for a lambda‐shaped parallel robot that incorporates data‐driven surrogates to facilitate control design. An inverse surrogate model is used to provide an efficient initialization of the control inputs for NMPC.
