„BLACK-SCHOLES MODEL USED TO EVALUATE STOCKS OPTIONS” [PDF]

open access: yesAnnals of the University of Oradea: Economic Science, 2010
Partial differential equation, parabolic Black-Scholes type, is used in evaluating equity options, that paying constant and continue dividends or in evaluate options in which interest rate, volatility and dividend are dependent on time.

Intensive Widmannstätten Nanoprecipitates Catalyze SnTe With State‐of‐the‐Art Thermoelectric Performance

open access: yesAdvanced Materials, EarlyView.
The intensive lath‐shaped Ag2Te Widmannstätten nanoprecipitates are in situ generated in SnTe via AgPbSbTe3 alloying, and align with the formation of the parallel type and twin type interfaces. These Widmannstätten nanoprecipitates effectively scatter phonons to reduce the lattice thermal conductivity, resulting in a significantly enhanced average ZT ...

Bimodal Spin Switch Emerging from Hybridized 2D MoS2/Ferromagnet Interfaces

open access: yesAdvanced Materials, EarlyView.
This study demonstrates a novel integration of 2D semiconductors with ferromagnets using pulsed laser deposition, revealing hybridization‐driven spin manipulation. Vertical spin valves with MoS2 and Ni(111) show exotic bimodal spin signals and strong deviations from Jullière's model. These results highlight the « 2D spinterfaces » key role in unlocking

Reduction of weakly nonlinear parabolic partial differential equations [PDF]

open access: yesJournal of Mathematical Physics, 2013
It is known that the Swift-Hohenberg equation \documentclass[12pt]{minimal}\begin{document}$\partial u/\partial t = -(\partial _x^2 + 1)^2u + \varepsilon (u-u^3)$\end{document}∂u/∂t=−(∂x2+1)2u+ɛ(u−u3) can be reduced to the Ginzburg-Landau equation (amplitude equation) \documentclass[12pt]{minimal}\begin{document}$\partial A/\partial t\break = 4\partial

Mie‐Resonant Metasurfaces with Controlled Silicon Oxidation in Electron‐Beam Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
Electron‐beam deposition is optimized to prevent silicon oxidation by controlling chamber pressure and deposition rate, yielding refractive index values comparable to other methods. This tunability enables precise control of optical properties. Mie‐resonant metasurfaces exhibit strong, tunable collective resonances, allowing the fabrication of silicon ...

Nonlinear functional integrodifferential equations in Hilbert space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1999
Let X be a Hilbert space and let Ω⊂Rn be a bounded domain with smooth boundary ∂Ω. We establish the existence and norm estimation of solutions for the parabolic partial functional integro-differential equation in X by using the fundamental solution.
