Fujifilm Neopan 100 SS (FF) **English:** A black and white photograph depicting a narrow alleyway with a brick-paved path. The alley is flanked by high walls on both sides, creating a sense of depth and leading the eye towards a door at the end. The shadows cast by the walls create a pattern of light and dark on the ground, adding texture to the scene. The door at the end of the alley is slightly ajar, with a ladder leaning against the wall nearby. **Chinese:** 一张黑白照片，描绘了一条狭窄的小巷，铺着砖块的小路。小巷两侧是…
Fujifilm Neopan 100 SS (FF) **English:** A black and white photograph showing a view through a slightly open door into a narrow alleyway. The door handle and hinge are visible on the left side of the image. The alleyway is paved with bricks and extends into the distance, with a few steps leading up to another level. The perspective gives a sense of depth and invites curiosity about what lies beyond. **Chinese:** 一张黑白照片，展示了通过一扇微开的门看到的狭窄小巷。门把手和铰链在图片的左侧可见。小巷铺着砖块，向远处延伸，几级台阶通向另一个高度。透视感给人一种深度感，并引发人…
Fujifilm Neopan 100 SS (FF) **English:** A black and white photograph of an entrance to a traditional building, featuring a decorative brick wall with a circular pattern near the top. The entrance is framed by brick walls, and the roof above shows some wear. The scene is slightly blurred, adding a sense of nostalgia and timelessness to the image. **Chinese:** 一张黑白照片，展示了一座传统建筑的入口，入口上方的砖墙上有一个圆形图案装饰。入口由砖墙围成，上方的屋顶显得有些破旧。场景略显模糊，为图片增添了一种怀旧和永恒的感觉。
Fujifilm Neopan 100 SS (FF) **English:** A black and white photograph capturing a string of traditional Chinese lanterns hanging from a wire. The lanterns are intricately designed and appear to be made of a translucent material. They are positioned in front of a building with a numbered plaque, and a security camera is visible on the right side of the image. The lanterns add a cultural and festive element to the scene. **Chinese:** 一张黑白照片，拍摄了一串悬挂在电线上的中国传统灯笼。灯笼设计精美，看起来是由半透明材料制成。它们位于一栋带有编号牌匾的建筑…

From Kardar-Parisi-Zhang scaling to soliton proliferation in Josephson junction arrays
We propose Josephson junction arrays as realistic platforms for observing nonequilibrium scaling laws characterizing the Kardar-Parisi-Zhang (KPZ) universality class, and space-time soliton proliferation. Focusing on a two-chain ladder geometry, we perform numerical simulations for the roughness function. Together with analytical arguments, our results predict KPZ scaling at intermediate time scales, extending over sufficiently long time scales to be observable, followed by a crossover to the a…

Morphology of Polarization States in Strained Ferroelectric Films
Ferroelectric thin films under epitaxial strain exhibit a variety of vortex-like topological polarization textures. To analyze them, we build on the Ginzburg-Landau-Devonshire framework and extend the previously introduced soft-domain approach. This formulation provides a compact variational theoretical description of polarization morphologies in strained PbTiO$_3$ films. It yields phase diagrams as a function of temperature, strain, and thickness, and clarifies the morphological structure of e…

Differential Inclusions for Gradient and Symmetrized Gradient Operators
In this article, we study the necessary and sufficient conditions for the existence of solutions in $W_0^{1,\infty}(Ω;\mathbb R^n)$ in the minimal dimension of $\textrm{span }E$ for the following problem: \begin{equation*} P(D)u\in E \textrm{ a.e. in }Ω, \end{equation*} where $P(D)= D$ or $D+D^{\top}$, and $E\subseteq \mathbb R^{n\times n}$ is a given set. We conclude this paper with some properties of real symmetric matrices.

Well-posedness and long-time behavior of a bulk-surface Cahn--Hilliard model with non-degenerate mobility
We study a bulk-surface Cahn--Hilliard model with non-degenerate mobility and singular potentials in two dimensions. Following the ideas of the recent work by Conti, Galimberti, Gatti, and Giorgini [Calc. Var. Partial Differential Equations, 64(3):Paper No. 87, 32, 2025] for the Cahn--Hilliard equation with homogeneous Neumann boundary conditions, we show the uniqueness of weak solutions together with a continuous dependence estimate for sufficiently regular mobility functions. Next, under weak…
