European option pricing under the approximate fractional Heston jump–diffusion model with a stochastic long-term mean

Alexandria Engineering Journal
To address the limitations of the traditional Heston model, which fails to capture asset price jumps, long-range dependence, and the term structure of implied volatility and variance swap curves, this study proposes an enhanced approximate fractional ...

Locking Metastable Topological Domains in Nematic Liquid Crystal Pi Cells

Advanced Functional Materials, EarlyView.
Selective photopolymerization in the presence of a controlled voltage defines permanent director walls that lock‐in metastable bend and twist configurations within nematic liquid crystal Pi cells. Q‐tensor simulations corroborate the experiments, demonstrating the topological state stabilization.

Enhanced Performance and In Situ TEM Investigation in High Entropy Alloy Electrode Based Memristors

Advanced Functional Materials, EarlyView.
This study utilizes in situ TEM, EDS, EELS, and APT to reveal switching in HEA/ZnO/Nb:STO RRAM. High diffusivity of Mn lowers the SET voltage to 1.5 V. Cr stabilizes the oxygen layer, while Fe, Co, and Ni stabilize the electrode. Based on these observations, the device achieves 30 ns switching, a 10⁷ memory window, and excellent endurance, being ...
