In this note we present rapidly convergent algorithms depending on the method of arithmetic-geometric means (AGM) for the computation of Jacobian elliptic functions and Jacobi's Theta-function. In particular, we derive explicit a priori bounds for the error accumulation of the corresponding Landen transform. AMS Classi cation: 65D20, 65G05

We describe an algorithm, AGM-X0(N), for point counting on elliptic curves of small characteristic p using p-adic lifts of their invariants associated to modular curves X0(N). The algorithm generalizes the contruction of Satoh [10], SST [11], and Mestre [9]. We describe this method and give details of its implementation for characteristics 2, 3, 5, 7, and 13.

In this paper, we compare and contrast two methods for the qualitative revision of (viz., “full”) beliefs. The first (“Bayesian”) method is generated by a simplistic diachronic Lockean thesis requiring coherence with the agent’s posterior credences after conditionalization. The second (“Logical”) method is the orthodox AGM approach to belief revision. Our primary aim will be to characterize the...

The distribution and levels of simian immunodeficiency virus (SIV) in tissues and plasma were assessed in naturally infected African green monkeys (AGM) of the vervet subspecies (Chlorocebus pygerythrus) by limiting-dilution coculture, quantitative PCR for viral DNA and RNA, and in situ hybridization for SIV expression in tissues. A wide range of SIV RNA levels in plasma was observed among thes...

One of the basic principles of the AGM theory [Alchourrón et al., 1985] is that belief changes should take place with minimal loss of previous beliefs. In the opinion of the AGM trio, the postulate of recovery guarantees minimal loss of contents in the contraction process.1 However, several authors have criticised the recovery postulate [Fermé, 1998; Makinson, 1987; Levi, 1991; Levi, 1997; Lind...

Apoptosis is an essential process in embryonic tissue remodeling and adult tissue homeostasis. Within the adult hematopoietic system, it allows for tight regulation of hematopoietic cell subsets. Previously, it was shown that B-cell leukemia 2 (Bcl-2) overexpression in the adult increases the viability and activity of hematopoietic cells under normal and/or stressful conditions. However, a role...

A release of (14)CO(2) not related to ornithine decarboxylase activity was found in crude leaf extracts from Lycopersicon esculentum, Avena sativa, and especially from the pyrrolizidine alkaloid-bearing Heliotropium angiospermum when incubated with [1-(14)C]- or [U-(14)C]ornithine. The total (14)CO(2) produced was about 5- to 100-fold higher than that due to ornithine decarboxylase activities c...

Abstract Response Gene to Complement (RGC)-32 modulates TGF-β-induced extracellular matrix secretion and the ability of astrocytes undergo reactive changes in vivo during experimental autoimmune encephalomyelitis (EAE). However, molecular pathways underlying these effects are still not well understood. In this study, we investigated how lack RGC-32 affects transcriptomic profile expression axon...

The design of smart terminals able to detect reachable frequency bands and configure them according to the available channel state information is a major focus of current research. Two main approaches are addressed in the literature: cooperative scenario and blind methods whom transmission parameters are unknown. Blind spectrum sensing and parameters estimation (at the receiver side) may guaran...
