Another explicit forms of dynamic substructuring approaches using dynamic constraints at joint nodes

Journal of Asian Architecture and Building Engineering
The dynamic substructuring design describes the dynamic responses in the modal, frequency and physical domains using coupling methods at joint nodes. This paper presents dynamic structuring methods to modify existing substructuring methods by merging the

System Identification and Sensor Calibration Methods for Commissioning Bearingless Machine Control Systems

Actuators
This paper presents a practical and comprehensive guide for commissioning the controllers of bearingless machines (BMs). While significant research has been conducted on the commissioning of electric machines (EMs) and magnetic bearings (MBs), relatively

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Estimation of generalised frequency response functions [PDF]

, 2009
Volterra series theory has a wide application in the\ud representation, analysis, design and control of nonlinear systems. A new method of estimating the Volterra kernels in the frequency domain is introduced based on a non-parametric algorithm. Unlike the traditional non-parametric methods using the DFT transformed input-output data, this new approach

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Frequency response computation for complex structures with damping and acoustic fluid

, 2004
textModal frequency response analysis is a very economical approach for large and complex structural systems since there is an enormous reduction in dimension from the original finite element frequency response problem to the number of modes ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

The Interpretation of Nonlinear Frequency Response Functions

, 1989
Analytical and graphical methods of interpreting generalised frequency response functions for nonlinear systems are derived. It is shown that nonlinear phenomena can be classified into intra-kernel and inter-kernel interference and that worst case responses can be computed.
