Modal parameters evaluation of a structure when adding constraints [PDF]

, 1997
In the present paper the problem of determining the new modal parameters of a structure when subjected to additional constraints is considered. The aim is to avoid performing a new modal analysis when a structure is modified by adding constraints.

Identification of modal parameters for complex structures by experimental modal analysis approach

Advances in Mechanical Engineering, 2016
In this research, we have proposed a methodology for experimental identification of modal parameters based on measurement of the frequency responses of structures with complex geometries and performed an overall investigation of structural behavior on a ...

Astrocyte heterogeneity in brain metastases

Molecular Oncology, EarlyView.
Astrocytes emerge as pivotal regulators of metastatic colonization, survival, immune remodeling, and therapy response associated with an increasing heterogeneity that requires spatially and longitudinally resolved approaches to uncover regulatory programs and guide context‐specific therapies.

Data compression for the modal analysis of spatially dense laser Doppler vibrometer measurements [PDF]

, 2015
This paper investigates a method which can be used to compress two-dimensional mobility shapes measured with scanning laser Doppler vibrometers. It is shown that the compressed data can be used as virtual measurements when estimating modal parameters ...

Structural model updating and prediction variability using Pareto optimal models [PDF]

, 2008
A multi-objective identification method for structural model updating based on modal residuals is presented. The method results in multiple Pareto optimal structural models that are consistent with the experimentally measured modal data and the modal ...

Preoperative circulating tumor cells integrated with imaging analysis for prognostic evaluation in head and neck squamous cell carcinoma

Molecular Oncology, EarlyView.
Detecting circulating tumor cells (CTCs) in blood before surgery may help predict outcomes in patients with head and neck squamous cell carcinoma (HNSCC). Here, we show when combined with tumor size and lymph node involvement from routine imaging, CTC status identifies high‐risk patients with poorer survival—offering a simple, minimally invasive tool ...

Time-varying modal parameters identification of large flexible spacecraft using a recursive algorithm [PDF]

, 2016
In existing identification methods for on-orbit spacecraft, such as eigensystem realization algorithm (ERA) and subspace method identification (SMI), singular value decomposition (SVD) is used frequently to estimate the modal parameters.

Time–Frequency Analysis of Railway Bridges Forced and Free Vibrations Identified by Wavelet Transform

Vibration
In this work, a time–frequency analysis of two railway bridges included in the InBridge4EU project database is presented. The study focuses on the identification of modal parameters from free responses after train passages and their comparison with ...

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

Molecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Analysis and interpretation of compressible fluid interaction upon the vibration of a circular membrane [PDF]

, 2013
The free vibration of a circular membrane in interaction with a fluid contained in a cylindrical boundary is analysed. The fluid is compressible and assumed inviscid.
