PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Analysis of instability causes in the bi‐dc converter and enhancing its performance by improving the damping in the IDA‐PBC control

IET Generation, Transmission & Distribution, 2021
The poor damping of bidirectional dc (bi‐dc) converter caused by constant power load makes power system prone to oscillation, and non‐minimum phase characteristic also jeopardises voltage stability.

Understanding friction induced damping in bolted assemblies through explicit transient simulation [PDF]

, 2014
The design of joints is seeing increased interest as one of the ways of controlling damping levels in lighter and more flexible aeronautic structures. Damping induced by joint dissipation has been studied for more than a decade, mostly experimentally due ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Hoop strain-Based Approach to Detecting Leak Phenomena

e-Journal of Nondestructive Testing
Detecting leakage in aging underground pipeline remains challenging due to limited accessibility and complex hydraulic conditions. This study explores a transient damping-based method for leakage detection using both internal water pressure and external

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch

International Journal of Adaptive Control and Signal Processing, EarlyView.
This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Adaptive Feedforward Cancellation Scheme Temporarily Using Negative Damping to Speed Up the Transient Response When Counteracting Periodic Disturbances

IEEE Access
Adaptive Feedforward Cancellation (AFC) is commonly used to counteract periodic disturbances in mechatronic systems in order to enhance the control performance. So far, AFC algorithms either use no or positive damping.

dynoGP: Deep Gaussian Processes for Dynamic System Identification

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces a novel class of deep models for system identification, dynamical deep Gaussian processes, which combine the strengths of data‐driven methods, such as those based on neural network architectures, with the ability to output a probability distribution for uncertainty representation.
