The volatility of its share price reflects the volatility of the market value of a bank’s assets. We present data for the volatilities of individual banks’ shares that are implied by the prices of options on the banks’ shares. We present evidence that implied volatilities (IV’s) better forecast actual, future volatilities of share prices than historical volatilities do. Banks’ IV’s are correlat...

The Afrotropical cremastine fauna (Hymenoptera: Ichneumonidae) is characterized by the near absence of the genus Cremastus, with a single species reported from Madagascar. The fauna is also characterized by the presence of several endemic genera. Among the latter is the exceptional monotypic genus Belesica. We describe two new species from these extremely rare Afrotropical genera, namely Belesi...

We review recent, and some less recent, measurements of several emission spectra of copper. The results are discussed with special emphasis on elucidating the structure of the Kα 1,2 and Kβ 1,3 diagram lines and their underlying transitions. These lines are found to contain ≈30 % contribution from 3d spectator hole transitions. Other multielectronic transitions, the 2p spectator hole (satellite...

Based upon flavor SU(3) symmetry, we perform global fits to charmless B decays into one pseudoscalar meson and one vector meson in the final states. We consider different symmetry breaking schemes and find that the one implied by näıve factorization is slightly favored over the exact symmetry case. The (ρ̄, η̄) vertex of the unitarity triangle (UT) constrained by our fits is consistent with other...

This paper looks at unobserved components models and examines the implied weighting patterns for signal extraction. There are three main themes. The rst is the implications of correlated disturbances driving the components, especially those cases in which the correlation is perfect. The second is how setting up models with t distributed disturbances leads to weighting patterns which are robust ...

Recent popularity of interactive AJAX-based Web 2.0 applications has given rise to a new breed of security threats: JavaScript worms. In this paper we propose Spectator, the first automatic detection and containment solution for JavaScript worms. Spectator performs distributed data tainting by observing and tagging the traffic between the browser and the Web application. When a piece of data pr...

Stating the general specifications of our interactive opera research project -specific spectator/composer, spectator/work, music/text relationships, specific kinematics, new graphical metaphors of musical entities, we intiate a multimedia creativiy environment which should enable to free the spectator’s emotion.
