Qualitative Properties Of Solutions Of Fully Nonlinear Equations And Overdetermined Problems [PDF]
In section 2 of part I, We study the maximum principles and radial symmetry for viscosity solutions of fully nonlinear partial differential equations. We obtain the radial symmetry and monotonicity properties for nonnegative viscosity solutions of fully ...

A metasurface‐enabled helical wavefront fingerprint (MHWF) paradigm is proposed for quantitative and specific retrieval of a liquid medium's refractive index and extinction coefficient. The liquid's complex dielectric response governs the wavefront evolution of the metasurface‐generated focused vortex beam, forming a distinctive three‐dimensional ...

Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

A transpiration‐inspired Janus nanofiber membrane creates a persistent dry‐wet interface that couples localized solar heating with hydration‐induced ion regulation. The asymmetric architecture sustains directional water and ion transport, suppresses salt accumulation, and enables simultaneous seawater evaporation and stable electricity generation ...

Symmetry and uniqueness for a hinged plate problem in a ball [PDF]
In this paper we address some questions about symmetry, radial monotonicity, and uniqueness for a semilinear fourth-order boundary value problem in the ball of $\mathbb R^2$ deriving from the Kirchhoff-Love model of deformations of thin plates.

An integrated polarimetry architecture based on a cholesteric liquid crystal waveguide polarization splitter overcomes the volumetric bottleneck in chip‐scale atomic magnetometers. By leveraging Bragg‐selective reflection and total‐internal‐reflection‐induced helicity inversion, this ultrathin device enables efficient circular polarization splitting ...

A Magnetic‐Driven Self‐Rotation‐Stabilized Miniature Swimming Robot
Inspired by the stable rotational descent of seeds in nature, this study designs a magnetic‐driven self‐rotation‐stabilized miniature swimming robot (MSMSR). Based on a resonance‐driven strategy, the robot exhibits high swimming performance, offering enhanced directional swimming and improved resistance to water flow disturbances compared to existing ...
