Phase structure and confinement properties of noncompact gauge theories I [PDF]
, 1995 In the context of reviewing noncompact lattice gauge models at zero and finite temperature we study in detail a contribution of the invariant measure and the time-like plaquette configurations to correlation functions, analyze the problem of the ...

Advanced Functional Materials, EarlyView.Modular diffractive deep neural network metasurfaces encode and reconstruct holograms across layer combinations and wavelengths, enabling secure, multifunctional operation. Each layer acts independently yet composes jointly, yielding up to m(2N −1) channels for m wavelengths and N layers.

Time-stable boundary conditions for finite-difference schemes solving hyperbolic systems: Methodology and application to high-order compact schemes [PDF]
We present a systematic method for constructing boundary conditions (numerical and physical) of the required accuracy, for compact (Pade-like) high-order finite-difference schemes for hyperbolic systems. First, a roper summation-by-parts formula is found

Geometrically‐Screened, Sterically‐Hindered Additive for Wide‐Temperature Aqueous Zinc‐Ion Batteries
Advanced Functional Materials, EarlyView.A molecular‑engineering strategy combining steric hindrance tuning with geometric optimization identifies cellobiose as an ideal additive for aqueous zinc‑ion batteries, enabling stable Zn deposition across a wide temperature range from −30 to 50 °C. Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a highly promising alternative to lithium ...

A compact finite element method for elastic bodies [PDF]
A nonconforming finite method is described for treating linear equilibrium problems, and a convergence proof showing second order accuracy is given. The close relationship to a related compact finite difference scheme due to Phillips and Rose is examined.

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus
Advanced Functional Materials, EarlyView.The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing
Advanced Functional Materials, EarlyView.A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...
