Mimicking Synaptic Plasticity: Optoionic MoS2 Memory Powered by Biopolymer Hydrogels as a Dynamic Cations Reservoir

open access: yesAdvanced Functional Materials, EarlyView.
Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

Polaronic and Electrochemical Signatures in Group IVB (Ti, Zr, Hf) Oxides: Unified SKP–DFT Insights for Tunable Transport in Energy and Electronic Devices

open access: yesAdvanced Functional Materials, EarlyView.
Charge carrier concentration and mobility in TiO2, ZrO2, and HfO2 powder films are experimentally mapped as a function of temperature. The results uncover polaron‐mediated transport regimes and field‐activated conduction, enabling the design of oxide‐based electronic and energy devices with thermally tunable functionality.

A probabilistic approach for the valuation of variance swaps under stochastic volatility with jump clustering and regime switching

open access: yesFinancial Innovation
The effects of stochastic volatility, jump clustering, and regime switching are considered when pricing variance swaps. This study established a two-stage procedure that simplifies the derivation by first isolating the regime switching from other ...

Enhanced Switching Performance in Single‐Crystalline PbTiO3 Ferroelectric Memristors for Replicating Synaptic Plasticity

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrated single‐crystalline PbTiO3‐based memristors with atomically sharp interfaces, well‐ordered lattices, and minimal lattice mismatch. The devices exhibited an ON/OFF ratio exceeding 105, high stability, and rich resistance‐state modulation.

Variance Risk Premia [PDF]

open access: yes
We propose a direct and robust method for quantifying the variance risk premium on financial assets. We theoretically and numerically show that the risk-neutral expected value of the return variance, also known as the variance swap rate, is well ...

Supramolecular Liquid Crystal Elastomer Adhesives: Role of Internal Damping and Hydrogen Bonding

open access: yesAdvanced Functional Materials, EarlyView.
The adhesion strength can be significantly enhanced through the molecular design of supramolecular liquid crystal elastomers (LCEs) that combine high internal damping from mesogen reorientation with abundant hydrogen‐bonding moieties. Solvent vapor annealing enables reversible, non‐thermal control of adhesion, offering potential for heat‐sensitive ...

The Sources of Volatility Transmission in the Euro Area Money Market: From Longer Maturities to the Overnight? [PDF]

open access: yes
This note investigates the transmission of volatility from longer maturities to the overnight segment of the Euro area money market. I use non-parametric estimates of the daily variance of swap rates to test for block exogeneity with respect to the ...

Higher‐Order Temporal Dynamics in Complementary Charge Trap Memristor for High‐Dimensional Reservoir Computing

open access: yesAdvanced Functional Materials, EarlyView.
A complementary charge‐trap memristor (CoCTM) featuring a unique current transient with tunable overshoot‐relaxation dynamics is introduced for high‐resolution reservoir computing. By leveraging higher‐order temporal dynamics from engineered trapping layers, the device generates multiple output states from a single input, forming rich, high‐dimensional
