Magnetic anomalies may be used to constrain magma ascent and are useful as precursors to eruptions especially when correlated with other geophysical and geochemical data. In this paper we present multiparameter data on the magnetics, dome morphology, geochemistry and seismicity associated with the December 2000^January 2001 eruptions, the largest of the recent eruptions at Popocatepetl Volcano....

The developmental course in the distance–speed–time domain is still a matter of debate. Traditional stage models are contested by theories of continuous development and adaptive thinking. In the present work, we introduce a formal framework for modelling the developmental course in this domain, grounding on Competence-based Knowledge Space Theory. This framework, as a more general case, widely ...

UNLABELLED Talocalcaneal middle facet coalitions are associated with rigid pes planovalgus that often requires surgical intervention. Simple resection of the coalition is preferred for symptomatic cases in the absence of rearfoot arthritis. While resection of the coalition will remove the osseous restriction of motion and may eliminate pain, the procedure does not specifically correct the conco...

Although the need for social connection is critical for early social development as well as for psychological well-being throughout the lifespan, relatively little is known about the neural processes involved in maintaining social connections. The following review summarizes what is known regarding the neural correlates underlying feeling of ‘social pain’, the painful experiences associated wit...

The problem of equivalence of binary forms under the general linear group is shown to be a special case of the problem of equivalence of particle Lagrangians under the pseudogroup of transformations of both the independent and dependent variables. The latter problem has a complete solution based on the equivalence method of Cartan. This leads to the determination of a universal function which r...

In this paper, we mainly announce the result: every Siegel-Hilbert cuspform of weight divisible by 4h and of square-free level relative to certain congruence subgroups is a linear combination of theta series. I N T R O D U C T I O N Theta series provides one of the two most explicit ways to construct holomorphic modular forms. The other way is by Eisenstein series. A virtue of theta series is t...

This paper aims to illustrate how combining multiple approaches can inform us about the neurobiology of ADHD. Converging evidence from genetic, psychopharmacological and functional neuroimaging studies has implicated dopaminergic fronto-striatal circuitry in ADHD. However, while the observation of converging evidence from multiple vantage points is convincing, it does not necessarily inform us ...
