Vibration response analysis of mistuned bladed disk with platform damper (Effect of friction force deviation on vibration characteristics)

Nihon Kikai Gakkai ronbunshu, 2015
Recently, a blade with friction damper has been used in a steam turbine and a gas turbine to improve the blade reliability. Especially, for the gas turbine blade in the upstream stage, a platform type damper has been widely used, where the damper pieces ...

Supression of mechanical oscillations in a nonlinear systems with restriction

Lietuvos Matematikos Rinkinys, 2023
The application of the dynamical dampers in the mechanical systems, when the sources of stimulation are impossible to abolish, is one of the ways to fight against the harmful vibrations.

Multimode cable vibration control using a viscous‐shear damper: Case studies on the Sutong Bridge

Structural Control & Health Monitoring, 2020
This study investigates multimode damping effects of a long cable attached with a viscous‐shear damper (VSD). A typical VSD comprises a casing box containing viscous medium and shearing plates with parts submerged in the medium.

Tension Estimation Method for Cable With Damper Using Natural Frequencies With Uncertain Modal Order

Frontiers in Built Environment, 2022
In the maintenance of cable structures, such as cable-stayed bridges, it is necessary to estimate the tension acting on the cables. In current Japanese practice, the cable tension is estimated from the cable’s natural frequency using vibration-based ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

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 ...

Design and optimization of pneumatic locking control system for underground coal mine dampers

Meikuang Anquan
In practical applications of coal mines, there is a low-probability phenomenon of double-opening in pneumatic dampers. To solve the problem of pneumatic damper locking failure, we first analyze the action logic of the pneumatic damper in the default ...

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.

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.
