In this paper, we examine the small time-to-expiry behaviour of implied volatility in models of exponential Lévy type. In the at-the-money case, it turns out that the implied volatility converges, as time-to-expiry goes to zero, to the square root of the Gaussian member of the driving Lévy process’ characteristic triplet. In particular, the limit is zero if the Lévy process has no Gaussian part...

The N * (1440), or Roper resonance, plays an important role in nucleon and nuclear dynamics as an intermediate state. The excitation of a Roper may mediate pion electro-and photoproduction processes 1 , pion and double pion production in N N reactions 2,3 , heavy ion collisions 4 , etc. In this context, the knowledge of the N N → N N * (1440) interaction and the πN N * (1440) and σN N * (1440) ...

Burrows serve many functions for animals by providing a location for rearing young, sleeping, hibernation, food storage, and protection from predators and environmental extremes (Reichman & Smith 1990; Kinlaw 1999). Architectural features of burrows such as depth, orientation, and number of entrances can enhance specific functions critical to the occupant’s fitness. In particular, burrow archit...

High-precision studies of Beyond-Standard-Model physics through accelerator-based neutrino oscillation experiments require a very accurate description neutrino–nucleus cross-sections in broad energy region, going from quasielastic scattering up to deep, inelastic scattering. In this work, we focus on the following processes: scattering, two-particle-two-hole excitations, and excitation first (D...

This article compares the books about Lifes of Thomas More written by Roper and Harpsfield work Tomás Moro Fernando de Herrera. The comparison is taken as a case in point divergent early development biographical genre England Spain. three texts were Catholic humanists, but under different contexts, which produced kinds text. Roper’s Harpsfield’s Catholicism, marked close contact with Morean tra...

This EDIS publication is the fifth of Talking Local series, a six-part series about Florida consumers and their perceptions local food. focuses on ways Extension agents can assist farmers ranchers in labeling, sale, promotion locally produced products. provides information consumers’ food to faculty who are interested programming or work with clientele. 4-page consumer flexibility term “local.”...
