Experimental Determination of Natural Frequencies of Prestressed Suspension Bridge Model

A suspension bridge is the most suitable type for a long-span bridge. Increased kinematic displacements are the major disadvantage of suspension bridges. This problem can be solved by application of prestressed cable truss.

Mode Shapes in Compliant Mechanisms, and a Procedure to Identify Appropriate Pseudo-Rigid-Body Model Type

, 2015
The mobility characteristics of compliant mechanisms are a function of the structural arrangement of the comprising segments and links, their types, as well as the load and/or displacement boundary conditions.

On complex mode shapes and their identification

Journal of Physics: Conference Series
Abstract In experimental modal analysis, proportional damping is a convenient simplification that allows practitioners to fit their data to a model. However, this simplification seriously reduces the number of free parameters for fitting, and some systems may be misrepresented by the assumption of proportional damping.

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

FEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Standard deviation as a suitable criterion for localizing damages in Nano- composite structures

e-Journal of Nondestructive Testing
Wavelet transform is a proper method for detecting damages in signals such as vibration mode shapes. This study introduces the standard deviation as a suitable criterion for selecting and analyzing wavelet function in damage detection of nano-laminated ...

Participation factor based identification of mode shapes

In practical vibration analysis, the identification of mode shapes in an operational deflection shape is a common problem. Based on modal-superposition theory, there is always a summation of several mode shapes involved.

Correlation between analytical result and experimental results of mode shapes

, 1999
Typically, even though natural frequencies obtained by analytical and experimental methods are compared quantitatively, mode shapes are compared only qualitatively.

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 ...
