Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Sharp decay estimates and smoothness for solutions to nonlocal semilinear equations
, 2015 We consider semilinear equations of the form p(D)u=F(u), with a locally bounded nonlinearity F(u), and a linear part p(D) given by a Fourier multiplier.

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells
Advanced Functional Materials, EarlyView.Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,

Imaging of Biphoton States: Fundamentals and Applications
Advanced Functional Materials, EarlyView.Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

Endpoint bounds for quasiradial Fourier multipliers
, 2016 We consider quasiradial Fourier multipliers, i.e. multipliers of the form $m(a(\xi))$ for a class of distance functions $a$. We give a necessary and sufficient condition for the multiplier transformations to be bounded on $L^p$ for a certain range of $p$.

Absolute Dilation of Fourier Multipliers
International Mathematics Research NoticesAbstract Let $ {\mathcal M}$ be a von Neumann algebra equipped with a normal semifinite faithful (nsf) trace. We say that an operator $ T:{\mathcal M} \to{\mathcal M} $ is absolutely dilatable if there exist another von Neumann algebra $ M $ with an nsf trace, a unital normal trace preserving $\ast $-homomorphism $ J: {\mathcal M} \to M $

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Advanced Functional Materials, EarlyView.Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Quasi-radial Fourier multipliers [PDF]
Studia Mathematica, 1986 We give sufficient conditions on functions m: [0,\(\infty)\to {\mathbb{C}}\) and \(\rho\) : \({\mathbb{R}}^ n\to [0,\infty)\) so that their composition \(m\circ \rho (x)=m(\rho (x))\), called a quasi-radial function, will be a Fourier multiplier on \(L^ p=L^ p({\mathbb{R}}^ n)\).
