Three Kyries and Sevenfold Amen

Dyadic data analysis with amen

Dyadic data on pairs of objects, such as relational or social network data, often exhibit strong statistical dependencies. Certain types of second-order dependencies, such as degree heterogeneity and reciprocity, can be well-represented with additive random effects models. Higher-order dependencies, such as transitivity and stochastic equivalence, can often be represented with multiplicative ef...

Acronyms Must always bE defiNed (AMEN).

To the Editor: In a recent article from a prominent cardiological journal, the authors compared major adverse cardiac event rates between primary coronary angioplasty and thrombolytic therapy. They reported their results for the PCAT collaboration, but never explained what the acronym PCAT stood for. That surprised and disappointed me, because according to the International Committee of Medical...

The sevenfold way of PKC regulation.

Protein kinase C (PKC) is a family of enzymes that are physiologically activated by 1,2-diacylglycerol (DAG) and other lipids. To date, 11 different isozymes, alpha, betaI, betaII, gamma, delta, epsilon, nu, lambda(iota), mu, theta and zeta, have been identified. On the basis of their structure and activators, they can be divided into three groups, two of which are activated by DAG or its surro...

On the Griffiths Group of the Cubic Sevenfold

In this paper we prove that the Griffiths group of a general cubic sevenfold is not finitely generated, even when tensored with Q. Using this result and a theorem of Nori, we provide examples of varieties which have some Griffiths group not finitely generated but whose corresponding intermediate Jacobian is trivial.
