Advanced Science, EarlyView.A continuous conductivity gradient is formed in a porous MXene/melamine foam via directional evaporation, thereby improving impedance matching and enhancing electromagnetic attenuation. The resulting monolithic composite delivers absorption‐dominant EMI shielding with ultralow reflection, offering a simple route toward lightweight EMI shielding ...

Electromagnetic Radiation Stimulated Learning in Perovskite Nickelates
Advanced Science, EarlyView.ABSTRACT Biological plasticity refers to the ability of synapses to strengthen or weaken over time. These adaptive properties play a fundamental role in learning and memory, spanning many orders of magnitude in timescales. Short‐term plasticity (STP) arises from rapid correlative activity, while long‐term plasticity (LTP) is governed by slower ...

Advanced Science, EarlyView.A robust, substrate‐independent fabrication approach overcomes the spectral and geometric limitations of traditional stray‐light suppression. By combining ink spray‐coating with self‐assembled microsphere mask etching, this method produces parabolic‐shaped microstructures on diverse planar and curved engineering components.

The near-parabolic geometry of external rays
Using Lavaurs maps and near-parabolic renormalization, we describe the degenerating geometry of external rays for quadratic polynomials when a periodic cycle becomes parabolic.

The geometry of the parabolic Hilbert schemes
, 2002 We discuss the parabolic Hilbert scheme of points on smooth surface, which is an interesting generalization of Hilbert scheme of points on surface. Some of the studies by Ellingsrud-Stromme, Goettsche, Cheah, Nakajima and Grojnowski can be generalized in our parabolic case.

Physics‐Based Compact Modeling of Advanced 3D Nanoscale Vertical NAND Flash Memory
Advanced Electronic Materials, EarlyView.For advanced 3D NAND flash memory, a unified compact model for SPICE is proposed that spans from the intrinsic unit cell to the full string and captures the electrostatic coupling with adjacent inhibit strings. It can successfully predict read behavior, program/erase dynamics, and interactions between neighboring cells, reflecting array‐level behavior ...

"On Approximation of the Solutions to Partial Differential Equations in Finance" [PDF]
This paper proposes a general approximation method for the solutions to second-order parabolic partial differential equations (PDEs) widely used in finance through an extension of Léandre's approach(Léandre (2006,2008)) and the Bismut identiy(e.g ...

Parabolic geometries, CR-tractors, and the Fefferman construction
Differential Geometry and its Applications, 2002 This is a survey article on the recent joint work of the author with A. R. Gover on the standard tractor bundle and its canonical linear connections in the geometry of nondegenerate CR structures of hyperbolic type. The author mainly treats three classical constructions in CR-geometry: (I) The standard tractor bundles and its linear connections, which ...
