A ∂-analogue of differential characters for complex manifolds is introduced and studied using a new theory of homological spark complexes. Many essentially different spark complexes are shown to have isomorphic groups of spark classes. This has many consequences: It leads to an analytic representation of O-gerbes with connection, it yields a soft resolution of the sheaf O by currents on the man...
Let the sign of a skew standard Young tableau be the sign of the permutation you get by reading it row by row from left to right, like a book. We examine how the sign property is transferred by the skew Robinson-Schensted correspondence invented by Sagan and Stanley. The result is a remarkably simple generalization of the ordinary non-skew formula. The sum of the signs of all standard tableaux ...
For a (standard) Young tableau T on [k], say that a tableau T ′ on [n] contains T as a subtableau if the cells of T ′ containing the elements of [k] are arranged as in T . McKay, Morse, and Wilf recently introduced the idea of quasirandom permutations and used this to find the limiting probability (as n → ∞) that a tableau on [n] contains a given tableau on [k] as a subtableau. Stanley then use...
This paper explores the performance of a new complete nonsystematic search algorithm learn-SAT on two types of 3-SAT problems, (i) an extended range of AIM problems [1] and (ii) structured unsolvable problems [2]. These are thought to present a difficult challenge for non-systematic search algorithms. They have been extensively used to study powerful special purpose SAT algorithms. We consider ...
The partially asymmetric exclusion process (PASEP) is an important model from statistical mechanics which describes a aystem of interacting particles hopping left and right on a one-dimensional lattice of n sites. It is partially asymmetric in the sense that the probability of hopping left is q times the probability of hopping right. Additionally, particles may enter from the left with probabil...

The analytic narratives project represents an effort to clarify and make explicit the approach adopted by numerous scholars trying to combine historical and comparative research with rational choice models. In order to understand instances of institutional origin and change, analytic narrativists insist on the combination of deep knowledge of the case and an explicit theoretical model. These re...
Autoethnography – a qualitative research method that combines characteristics of ethnography and autobiography – is gaining momentum within the creative and performing arts as a research tool, partly because of the opportunity it provides for writers, artists, performers and others to reflect critically upon their personal and professional creative experiences. In recent years, ‘analytic autoet...
the analytic signal method is a semiautomatic method for estimating the location of causative bodies in magnetic and gravity methods. the application of analytic signal for interpretation of two dimensional (2d) structures was introduced by nabighian (1972). the analytic signal is defined as a complex function in which the real and imaginary parts are a pair of hilbert transforms. in other word...
Individuals in the developing world live in conditions of intense exposure to enteric pathogens due to suboptimal water and sanitation. These environmental conditions lead to alterations in intestinal structure, function, and local and systemic immune activation that are collectively referred to as environmental enteropathy (EE). This condition, although poorly defined, is likely to be exacerba...
