Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Singular Perturbation Theory in Output Feedback Control of Pure-Feedback Systems

Iranian Journal of Electrical and Electronic Engineering, 2016
This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is ...

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

An iterative output feedback controller-design strategy for energy-to-peak structural vibration control

Journal of Asian Architecture and Building Engineering
To address the issue of inadequate control effect resulting from the challenge of measuring state feedback information comprehensively, this paper proposes an iterative output feedback energy-to-peak control method that solely depends on partial external

Nonfragile H∞ Static Output Feedback Control for Time-Delay Systems

IEEE Access
This study addresses the nonfragile static output feedback control problem in time-delay systems and introduces an $H_{\infty }$ control strategy developed through the Chebyshev spectral continuous time approximation (CHsCTA).

Recent Advances in Static Output-Feedback Controller Design with Applications to Vibration Control of Large Structures [PDF]

Modeling, Identification and Control, 2014
In this paper, we present a novel two-step strategy for static output-feedback controller design. In the first step, an optimal state-feedback controller is obtained by means of a linear matrix inequality (LMI) formulation.

ℋ∞ control of nonlinear systems via output feedback: controller parameterization [PDF]

, 1994
The standard state space solutions to the ℋ∞ control problem for linear time invariant systems are generalized to nonlinear time-invariant systems. A class of local nonlinear (output feedback) ℋ∞ controllers are parameterized as nonlinear fractional ...

Distributed Output-Feedback LQG Control with Delayed Information Sharing

, 2012
This paper develops a controller synthesis method for distributed LQG control problems under output-feedback. We consider a system consisting of three interconnected linear subsystems with a delayed information sharing structure. While the state-feedback
