On the Regularity of Non-scattering Anisotropic Inhomogeneities [PDF]
In this paper we examine necessary conditions for an anisotropic inhomogeneous medium to be non-scattering at a single wave number and for a single incident field. These conditions are expressed in terms of the regularity of the boundary of the inhomogeneity.

Regularity of anisotropic refinable functions [PDF]
This paper presents a detailed regularity analysis of anisotropic wavelet frames and subdivision. In the univariate setting, the smoothness of wavelet frames and subdivision is well understood by means of the matrix approach. In the multivariate setting, this approach has been extended only to the special case of isotropic refinement with the dilation ...

Regularity of solutions to anisotropic nonlocal equations [PDF]
AbstractWe study harmonic functions associated to systems of stochastic differential equations of the form $$dX_t^i=A_{i1}(X_{t-})dZ_t^1+\cdots +A_{id}(X_{t-})dZ_t^d$$ d X t i = A i 1 ( X t - ) d Z t 1 + ⋯ + A id ( X t - ) d Z t d , $$i\in \{1,\dots ,d\}$$ i ∈ { 1 , ⋯ , d } , where $$Z_t^j$$ Z t j are independent one ...

Anisotropic regularity principle in sequence spaces and applications [PDF]
We refine a recent technique introduced by Pellegrino, Santos, Serrano and Teixeira and prove a quite general anisotropic regularity principle in sequence spaces. As applications, we generalize previous results of several authors regarding Hardy–Littlewood inequalities for multilinear forms.

Hölder regularity for bounded solutions to a class of anisotropic operators [PDF]
The authors consider the following class of anisotropic elliptic equations \[ \sum^{N-1}_{i=1}\frac{\partial}{\partial x_i} A_{q,i} (x, u, Du) + \frac{\partial}{\partial x_N} A_p(x, u, Du) =0\quad\text{in}\quad \Omega, \tag{1} \] with \(\Omega\subset \mathbb{R}^N\) a regular domain, \(p > q > 1\). The functions \(A_{q,i} (x, u, Du)\) and \(A_p(x, u, Du)

Some regularity results for anisotropic motion of fronts
This paper concerns the regularity of fronts propagating in the environment being anisotropic and inhomogeneous. It is proved that under appropriate assumptions there is at most one normal direction at each point of the front. With the help of this result the author shows that convex fronts are \(C^{1,1}\).

A Generative AI Framework to Predict Cardiomyocyte Contraction Function From Single Static Images [PDF]
A single static hiPSC‐cardiomyocyte image is fed into a U‐Net‐GAN framework, which directly predicts a pixel‐resolved contraction heatmap without time‐lapse imaging. StyleGAN2‐generated synthetic cell–heatmap pairs augment training, improving prediction fidelity (SSIM = 0.84).

Stable Anisotropic Regularization
Given the success of Large Language Models (LLMs), there has been considerable interest in studying the properties of model activations. The literature overwhelmingly agrees that LLM representations are dominated by a few "outlier dimensions" with exceedingly high variance and magnitude.

A regularity result for a class of anisotropic systems
We provide partial regularity of minimizers of the functional I(u) = \int\Omega G(Du), where G is a convex integrand satisfying anisotropic growth condition. No special structure assumption is needed on G.
