The strain gradient elasticity via nonlocal considerations [PDF]
arXiv, 2022 Strain gradient elasticity and nonlocal elasticity are two enhanced elastic theories intensively used over the last fifty years to explain static and dynamic phenomena that classical elasticity fails to do. The nonlocal elastic theory has a clear differentiation from the classical case by considering stresses in a point of the continuum as an integral ...

Phys. Rev. Lett. 121, 064301 (2018), 2018 In this work, we introduce an elastic analog of the Purcell effect and show theoretically that spherical nanoparticles can serve as tunable and robust antennas for modifying the emission from localized elastic sources. This effect can be qualitatively described by introducing elastic counterparts of the familiar electromagnetic parameters: local ...

Elastic Gradient Descent, an Iterative Optimization Method Approximating the Solution Paths of the Elastic Net [PDF]
Journal of Machine Learning Research 24 (2023) 1-53, 2022 The elastic net combines lasso and ridge regression to fuse the sparsity property of lasso with the grouping property of ridge regression. The connections between ridge regression and gradient descent and between lasso and forward stagewise regression have previously been shown.

Iterative methods for constructing an equations of non-closed shells solution
Structural Mechanics of Engineering Constructions and Buildings, 2021 The elasticity relations are transformed to a form that allows, in accordance with the previously proposed Saint-Venant - Picard - Banach method, to iteratively calculate all the required unknowns of the problem. The procedure for constructing a solution

Nanoparticle elasticity regulates phagocytosis and cancer cell uptake
Science Advances, 2020 The deformation of soft nanocapsules during cell binding and endocytosis leads to a lower cellular uptake than the stiff ones. The ability of cells to sense external mechanical cues is essential for their adaptation to the surrounding microenvironment ...
