Discover option pricing theory, utilized to determine option value using models like Black-Scholes. Learn how variables impact the probability of profits at expiration.

This study explains the physics and mathematics of how and why a hula hoop can be suspended against gravity. We identify this activity as an example of a more general form of mechanical levitation ...

It has been well observed that the horizontal component of the magnetic field at photosphere changes rapidly and irreversibly after solar eruptions. Specifically, the horizontal magnetic field near ...

Abstract: A novel theory is proposed in this article to design a bandpass frequency-selective surface (FSS) with a stable angular response. Based on this theory, the performance of the structure is ...

The sliding friction of elastomers has been investigated numerically and theoretically for the line contact between a cylindrical rigid indenter and a “frictionless” Kelvin–Voigt foundation. The onset ...

Zoom, for all its privacy and security issues, has rocketed to household-name status in the days of social distancing, becoming the go-to digital meeting hub for personal and professional purposes ...

Royalty-free licenses let you pay once to use copyrighted images and video clips in personal and commercial projects on an ongoing basis without requiring additional payments each time you use that ...

Single-particle characterization of the impact response has unveiled design principles to focus and control stress propagation in macroscopic granular crystalline arrays. We demonstrate that similar ...

Abstract: A new formula is developed for the surface impedance of a nonlinear magnetic conductive semi-infinite slab. The impedance expression allows for proper incorporation of the nonlinear ...
