Disturbance attenuation–based sliding mode control with disturbance observer for mismatched uncertain system

Advances in Mechanical Engineering, 2017
A disturbance attenuation–based sliding mode control approach with an extended disturbance observer is proposed for systems with mismatched uncertainties. A novel adaptive sliding surface consisting of the disturbance estimation is presented to eliminate

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Application of Adaptive Sliding Mode Control with an Ellipsoidal Sliding Surface for Vehicle Distance Control

SICE Journal of Control, Measurement, and System Integration, 2017
This paper proposes a sliding mode control with an ellipsoidal sliding surface for vehicle distance control. The performance of two different sliding surfaces, namely ones that are ellipsoidal and linear, is evaluated under the same conditions.

Adaptive Higher-Order Sliding Mode Control for Islanding and Grid-Connected Operation of a Microgrid

Energies, 2018
Grid-connected and islanding operations of a microgrid are often influenced by system uncertainties, such as load parameter variations and unmodeled dynamics.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Convergence rate sliding mode control of permanent magnet synchronous motor based on expanded sliding mode observer

Journal of Engineering and Applied Science
The aim is to address the limitations of conventional sliding mode control for PMSM, namely the problems of sliding mode oscillation, load disturbance, and poor control accuracy. An improved sliding mode control strategy for PMSM is proposed based on the

Genetic-based sliding mode fuzzy controller design [PDF]

, 2010
In this paper, we proposed a genetic-based sliding mode fuzzy controller design method to avoid the chattering phenomena in traditional sliding mode controller (SMC), and shorten the hitting time of the controlled system.

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

Molecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.
