We survey recent work on normal functions, including limits and singularities of admissible normal functions, the Gri ths-Green approach to the Hodge conjecture, algebraicity of the zero-locus of a normal function, Néron models, and MumfordTate groups. Some of the material and many of the examples, esp. in §§5− 6, are original. In a talk on the theory of motives, A. A. Beilinson remarked that a...

A higher-order, embedded boundary projection method for axisymmetric, unsteady, low-Mach number combustion is used to model a natural gas ame from a 300kW IFRF burner in the Burner Engineering Research Laboratory (BERL) at Sandia National Laboratory under hot wall conditions. The numerical predictions presented are the late simulated-time results of a computation of unsteady ow in the furnace. ...

State-reduction and the notion of “actuality” are compared to “passage”through time and the notion of “the present”; already in classical relativity the latter give rise to di¢ culties. The solution proposed here is to treat both tense and value-de…niteness as relational properties or “facts as relations”; likewise the notions of change and probability. In both cases “essential” characteristics...

Purpose Recognising the importance of universities in achievement social and global objectives, this paper aims to study relevance reporting initiative (GRI) methodology for University Social Responsibility (USR) activities, taking into account specificity higher education institutions (HEI). Design/methodology/approach After a review literature background, European HEI reports prepared accordi...

The modi cation methods described in this paper combine characteristics of PSOLA-based methods and algorithms that resynthesize speech from its short-time Fourier magnitude only. The starting point is a short-time Fourier representation of the signal. In the case of duration modi cation, portions, in voiced speech corresponding to pitch periods, are removed from or inserted in this representati...

782 American Journal of Botany 97(5): 782–796, 2010; http://www.amjbot.org/ © 2010 Botanical Society of America Understanding how reproductive traits evolved in the past leads to important insights into how organisms adapted. In sexually reproducing organisms, traits associated with outcrossing are thought to be under strong selection because of their direct effect on reproductive success; the ...
