Vibration and buckling of cross-ply composite beams using refined shear deformation theory [PDF]

, 2012
Vibration and buckling analysis of cross-ply composite beams using refined shear deformation theory is presented. The theory accounts for the parabolical variation of shear strains through the depth of beam.

Dynamic instability of imperfect laminated sandwich plates with in-plane partial edge load

Latin American Journal of Solids and Structures
Dynamic instability of laminated sandwich plates having inter-laminar imperfections with in-plane partial edge loading is studied for the first time using an efficient finite element plate model.

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 ...

The refined theory and the decomposed theorem of a transversely isotropic elastic plate

, 2013
The refined theory of a transversely isotropic elastic plate is analysed. Based on the transversely isotropic elastic theory, a refined theory for bending thick plates is derived using the Elliott-Lodge's solution and Lur'e method without ad ...

Wave Dispersion Analysis of Functionally Graded GPLs-Reinforced Sandwich Piezoelectromagnetic Plates with a Honeycomb Core

Mathematics, 2022
This paper studies wave propagation in a new structure composed of three layers. The upper and lower layers are made of a piezoelectromagnetic material reinforced with graphene platelets (GPLs) that may be uniformly disseminated or continuously varied ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Analysis of the mechanical behavior of functional gradient porous plates on an elastic foundation

Scientific African
Summary: This study presents an in-depth analysis of the bending behavior of porous functionally graded material (P-FGM) plates resting on a Winkler–Pasternak elastic foundation. Two types of transverse loading are considered: uniform and sinusoidal. The

Static and dynamic behaviors of laminated composite plates resting on elastic foundation

Journal of Building Materials and Structures, 2022
This present study consists to analyze the mechanical buckling and the free vibration stabilities of antisymmetric cross-ply and angle-ply laminated composite plates using a refined high order shear deformation theory of four variables against five in ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Refined theory for linearly elastic plates: Laminae and laminates [PDF]

Mathematics and Mechanics of Solids, 2011
It is well known that bending and stretching modes of deformation in linearly-elastic plates decouple at leading order in thickness provided that the mid-plane is a plane of reflection symmetry of the three-dimensional material properties. This situation being the exception rather than the norm, it is important to have a model that accommodates ...
