Linear Polarimetry with γ→ e+e− Conversions
γ-rays are emitted by cosmic sources by non-thermal processes that yield either non-polarized photons, such as those from π0 decay in hadronic interactions, or linearly polarized photons from synchrotron radiation and the inverse-Compton up-shifting of these on high-energy charged particles. Polarimetry in the MeV energy range would provide a powerful tool to discriminate among “leptonic” and “...
متن کاملLogical Conversions
As I have argued elsewhere [10], and as summarized in the first two sections below, it turns out to be both logically and semantically revealing to acknowledge the existence of converse, or conversely construed, quantifiers, which mirror their classical, or classically construed, counterparts. In this paper I argue that classically construed quantifiers in their turn mirror their conversely con...
متن کاملCommuting Conversions vs. the Standard Conversions of the "Good" Connectives
Commuting conversions were introduced in the natural deduction calculus as ad hoc devices for the purpose of guaranteeing the subformula property in normal proofs. In a well known book, Jean-Yves Girard commented harshly on these conversions, saying that ‘one tends to think that natural deduction should be modified to correct such atrocities.’ We present an embedding of the intuitionistic predi...
متن کاملSexy gene conversions: locating gene conversions on the X-chromosome
Gene conversion can have a profound impact on both the short- and long-term evolution of genes and genomes. Here, we examined the gene families that are located on the X-chromosomes of human (Homo sapiens), chimpanzee (Pan troglodytes), mouse (Mus musculus) and rat (Rattus norvegicus) for evidence of gene conversion. We identified seven gene families (WD repeat protein family, Ferritin Heavy Ch...
متن کاملOnline to Batch Conversions
We have recently been studying the case where have a training set T generated from an underlying distribution and our goal is to find some good hypothesis, with respect to the true underlying distribution, using the training set T . We now examine how to use online learning algorithms (which work on individual, arbitrary sequences) in a stochastic setting. Let us consider the training set T as ...
