Modeling and pricing of space weather derivatives

Abstract: This article proposes a pricing model for space weather derivatives with payout depending on solar activity. By measuring the disturbance of the Earth’s magnetosphere, it is possible to price space weather derivatives which trigger a payoff if a certain level of energization is reached. Since energetic particles emitted by the Sun are a non-tradeable quantity, unique prices of contracts in an incomplete market are obtained using inverse transformation sampling as well as the market price of risk. We find a step-wise decline of option prices with increasing barriers of Kp-index values, a dependence of the option prices on the sunspot cycle, as well as reduced sensitivity of longer-dated maturities for higher Kp-index values.

Measuring acceleration using the Purcell effect

Abstract: We show that a two-level atom resonantly coupled to one of the modes of a cavity field can be used as a sensitive tool to measure the proper acceleration of a combined atom-cavity system. To achieve it we investigate the relation between the transition probability of a two-level atom placed within an ideal cavity and study how it is affected by the acceleration of the whole. We indicate how to choose the position of the atom as well as its characteristic frequency in order to maximize the sensitivity to acceleration.

The Liturgical Argument in Apollinarius: Help and Hindrance on the Way to Orthodoxy

Abstract: In the essay “Creed or Chaos?” written in the midst of the turmoil of World War II, British mystery novelist Dorothy L. Sayers defended the relevance of the creeds produced during the doctrinal debates of the fourth and fifth centuries to the lives of modern Christians. The theological dogmas contained in such documents as the Nicene Creed (325) or the Chalcedonian Definition (451) are not, she notes wittily, “a set of arbitrary regulations invented a priori by a committee of theologians enjoying a bout of all-in dialectical wrestling,” but were “hammered out under pressure of urgent practical necessity” to resolve theological controversies that had real impact on the discipleship of ordinary Christians. To put matters at their simplest, the trinitarian controversies revolved around the question of whether Christ was divine, and so capable of saving humankind from sin and death. The christological controversies, at least in their earliest stage, debated whether Christ was really human, truly the God-made-man capable of healing wounded humanity and providing aviable role model for Christians to follow in the living of a redeemed life. At stake in both controversies was a convincing explanation of the central Christian tenet that “Jesus saves” for those who profess to be his followers.

Captivity Affects Head Morphology and Allometry in Headstarted Garter Snakes, Thamnophis sirtalis.

Abstract: In response to the growing number of amphibian and reptiles species in decline, many conservation managers have implemented captive breeding and headstarting programs in an effort to restore these populations. However, many of these programs suffer from low survival success, and it is often unclear as to why some individuals do not survive after reintroduction. Here I document changes to head morphology in the eastern garter snake, Thamnophis sirtalis, in response to time spent in captivity. Thamnophis raised on three diet treatments all differed in head size from wild individuals, and head size differed between the three treatments. Overall, head size was smaller in all three diet treatments than in wild snakes, potentially limiting the available prey for the captive garter snakes. Allometric patterns of growth in head size were also different for each diet treatment. Several potential implications of these changes in morphology are discussed, and what these changes may mean for other species that are part of headstarting and reintroduction programs.
