In this paper, we focus on introducing the Variance Swap and estimating the portfolios. The portfolios of the Variance Swap are optimized based on maximizing the distorted expectation given the index of acceptability. The variance strike is calculated from the option surface calibration. The realized variance is constructed through Hardy-Littlewood transform considering the highly correlated au...

The cross-sections of relativistic deuteron reactions on natural copper were studied in detail by means of activation method. The copper foils were irradiated during experiments with the big Quinta uranium target at Joint Institute for Nuclear Research (JINR) in Dubna, Russia. The deuteron beams with energies ranging from 1 GeV up to 8 GeV were produced by JINR Nuclotron. Residual nuclides were...

We extend the standard fireball model, widely used to interpret gamma-ray burst (GRB) afterglow light curves, to include energy injections, and apply the model to the afterglow light curves of GRB 990510, GRB 000301C and GRB 010222. We show that discrete energy injections can cause temporal variations in the optical light curves and present fits to the light curves of GRB 000301C as an example....

The establishment of the quantitative precipitin reaction as an analytical-chemical procedure by Heidelberger and Kendall (1) was followed in 1937 by Kendall's original use of the method in the estimation of human serum proteins in health and disease (2, 3). A major drawback to the use of this immunochemical method for obtaining meaningful human serum protein values has concerned the purity or ...

The effects of proton and gamma radiation are compared for several types of integrated circuits with complex internal design and failure modes that are not as straightforward as the input bias current mechanism that is frequently used to study damage effects in linear devices. New circuit failure mechanisms were observed in voltage regulators that cause them to fail at much lower levels when th...

Passive anaphylaxis of the guinea pig has been subjected to numerous immunological studies (1). They have established for both systemic (2) and cutaneous anaphylaxis (3) the levels of specific antibody required, and the need for a latent period of sensitization (4, 5) which is generally believed to be the time required for the binding of the antibody to tissue receptors. Further evidence for an...

High energy photons are a powerful probe for astrophysics and for fundamental physics under extreme conditions. During the recent years, our knowledge of the most violent phenomena in the Universe has impressively progressed thanks to the advent of new detectors for high energy gamma rays. Observation of γ-rays gives an exciting view of the high energy universe thanks to the current (AGILE) and...

Environmental biomonitoring has demonstrated that organisms such as crustaceans, fish and mushrooms are useful to evaluate and monitor both ecosystem contamination and quality. Particularly, some mushroom species have a high capacity to retain radionuclides and some toxic elements from the soil and the air. The potential of mushrooms to accumulate radionuclides in their fruit-bodies has been we...

HETE-2 has provided strong evidence that the properties of X-Ray Flashes (XRFs) and GRBs form a continuum, and therefore that these two types of bursts are the same phenomenon. We show that both the structured jet and the uniform jet models can explain the observed properties of GRBs reasonably well. However, if one tries to account for the properties of both XRFs and GRBs in a unified picture,...
