"An Asymptotic Expansion Scheme for the Optimal Investment Problems" [PDF]
We shall propose a new computational scheme for the evaluation of the optimal portfolio for investment.Our method is based on an extension of the asymptotic expansion approach which has been recently developed for pricing problems of the contingent ...

Persistent intermediate photoluminescence superlinearity in metal halide perovskites challenges the conventional interpretation of β as a fixed recombination‐order indicator. Correlated steady‐state and time‐resolved measurements support a condition‐dependent carrier–lattice relaxation framework, suggesting that β and photoluminescence quantum yield ...

A multifunctional vertical bulk‐heterojunction transistor (MVBT) with amorphous GaOx integrates four functionalities within a single neuromorphic device. Gate‐source operation enables 254 nm deep‐ultraviolet sensing and threshold neuronal firing, whereas three‐terminal operation supports broadband UV–vis‐NIR synaptic functions and bias‐controlled ...

Relaxation cycles of the generalized pulsed neuron equation
In the paper we analyze the generalized model of the V. V. Mayorov and I. Yu. Myshkin pulsed neuron. The neuron equation contains a delay of the sodium conductance with respect to the transmembrane potential as well as the potassium one.

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors
Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,

On the asymptotic behavior of solutions to nonlinear ordinary differential equations
We discuss a number of issues important for the asymptotic integration of ordinary differential equations. After developing the tools required for application of the fixed point theory in the investigation, we present some general results about the long ...
