Fast-Decaying Polynomial Reproduction

Polynomial reproduction plays a relevant role in deriving error estimates for various approximation schemes. Local reproduction in a quasi-uniform setting is a significant factor in the estimation of error and the assessment of stability but for some computationally relevant schemes, such as Rescaled Localized Radial Basis Functions (RL-RBF), it ...

Efficient Charge Transport in Zero‐Dimensional Perovskite for Ultrahigh‐Sensitivity X‐Ray Detection

Advanced Functional Materials, EarlyView.
A novel mono‐octahedral 0D Bi‐based Dpy3Bi2I12 perovskite strengthens the internal hydrogen bonds and forms a quasi‐2D lattice, exhibits exceptional charge transport and mobility, achieving high X‐ray sensitivity and ultralow‐dose imaging, and setting a new benchmark for 0D detector performance.

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

Advanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Decadimento uniforme per equazioni integro-differenziali lineari di Volterra

Bruno Pini Mathematical Analysis Seminar, 2011
This talk is devoted to some recent results concerning the exponential and the polynomial decays of the energy associated with a linear Volterra integro-differential equation of hyperbolic type in a Hilbert space, which is an abstract version of the ...

Decay estimates for oscillatory integrals with polynomial phase

Journal of Mathematical Analysis and Applications, 2003
The paper deals with oscillatory integrals \(\int^b_a e^{i\lambda \varphi(t)}dt\) with phase \(p(t)\) being a real monic polynomial of degree \(n\) and big positive parameter \(\lambda\). It is supposed that for some \(j\), \(1\leq j\leq n-1\), the \(j\)-th derivative \(p^{(j)}(t)\) of \(p(t)\) has real and simple roots only.

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz

Advanced Materials, EarlyView.
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

Strong stability results for a Timoshenko system with thermoelasticity and two fractional damping terms

Boundary Value Problems
This paper investigates a Timoshenko system with two fractional damping terms acting on the transverse displacement and rotation angle equations, coupled with a thermoelastic effect governed by the Coleman–Gurtin law for heat flux.

Polynomial Decay of Correlations for Flows, Including Lorentz Gas Examples [PDF]

Communications in Mathematical Physics, 2019
We prove sharp results on polynomial decay of correlations for nonuniformly hyperbolic flows. Applications include intermittent solenoidal flows and various Lorentz gas models including the infinite horizon Lorentz gas.
