Nonarchimedean differential modules and ramification theory
… polyannuli. Then I apply these results to the ramification theory and deduce the fundamental result, Hasse-Arf theorem, for ramification filtrations defined by Abbes and Saito. Also, we include a comparison theorem to differential conductors and Borger's conductors in the equal characteristic …

Logarithmic Gromov-Witten theory and double ramification cycles
… Gromov-Witten cycles with the higher double ramification cycles. In the second paper (joint work with Patrick Kennedy-Hunt and Qaasim Shafi) we prove a refined tropical correspondence theorem for higher genus descendant logarithmic Gromov-Witten invariants of toric surfaces with a top lambda …

PSL(2,7)-Extensions with Certain Ramification at Two Primes
We conduct a parallel Hunter search in order to find a degree 7 number field K ramified at primes q and p with discriminant d(K)=q^6 p^2 where q=11 and 2<p<104. The number field we seek will satisfy certain criteria allowing for refinement of a conjecture of Ash, Doud, and Pollack. In the course of …

Maximal 2-Extensions of Number Fields With Limited Ramification
Let K be a number field, p a rational prime, and S a finite set of primes of K, none of which lies above p. Let K S be the maximal pro-p extension of K unramified outside S, and let GS = Gal(KS/K). In the case K = Q , p = 2, S a set of two odd primes, we find a presentation of GS given certain …

Brill-Noether-type theorems with a movable ramification point
… Pr. These theorems can be extended to include ramification conditions at fixed general points. This thesis deals with the problem of imposing a ramification condition at an unspecified point. We solve the problem completely in dimension 1, prove a closed-form existence criterion and a …

Ramification of Social Assistance Act 13 of 2004 intentions, on social relief programme based on Child Support Grant at Ha-Mutsha Area in Vhembe District, Limpopo Province
… research was to gain an understanding of the ramifications of the Social Assistance Act 13 of 2004 on the Social Assistance Programmes, based on the child-support grant, at Ha-Mutsha area in Vhembe District, Limpopo Province. The purpose of the study was to recommend solutions to discourage …

The role of tubulin in ganglioside-induced ramifications in cultured rat brain microglia
… role as microglial activators, induce microglial ramifications. To identify the cytoskeletal components involved in microglial ramification, we stimulated cells with gangliosides in the absence or presence of cytoskeletal inhibitors and examined the resultant morphological changes. While …

Branch junction constriction and hydraulic limitation in two species in the Cape Proteaceae : a mechanism explaining the trade-off between longevity and degree of ramification in the Cape Proteaceae
… the trade-off between longevity and increased ramification in species of the Cape Proteaceae. This was done by establishing if branch nodes are regions of greater resistance to xylem sap flow in the study species; attempting to quantify nodal resistance for a plant as a whole; and by …

The Inhibitory Effect of Rhododendron maximum L. (Ericaceae) Thickets on Mycorrhizal Colonization of Canopy Tree Seedlings
… colonization. Mycorrhizal colonization and ramification index (# mycorrhizae cm-1) were depressed and colonization by Cenococcum geophilum increased in blocks with versus without Rm. After the first year, percent colonization of T. canadensis not in Rm thickets (62 %) was three times higher …

Constructing and Tabulating Dihedral Function Fields
… dihedral function fields with prescribed ramification and fixed quadratic resolvent field, when k0 is a perfect field and not necessarily finite. We give a detailed description of this Kummer theoretic approach when k0, or a quadratic extension thereof, contains the l-th roots of unity. …

p-adic L-functions and the Geometry of Hida Families
… of a certain intersection multiplicity and ramification over the weight space. Our methods involve proving a converse to a result of Vatsal relating congruences between eigenforms to their algebraic special $L$-values and then $p$-adically interpolating congruences using formal models. These …

Toward a deformation theory for Galois representations of function fields
… be extended and refined to allow only restricted ramification at the places of K, and can be a tool for analyzing one-dimensional P-adic representations. We then turn to the problem of classifying those representations which can be realized as the action of the Galois group on the division points …

O! Canada? : a pavilion for the 2010 World Exposition in Shanghai
… that is their apotheosis. Also addressed are the ramification of large crowds on the display of objects, the potential for representing national identity without recourse to romanticism or nostalgia and economic and ecological responsibility in view of the ephemeral nature of expo pavilions.

Effects of turbidity on the foraging abilities of brook trout (Salvelinus fontinalis) and smallmouth bass (Micropterus dolomieu)

Action, Time and Space in Description Logics
… we offer DL-tailored solutions to the frame and ramification problem. One of the main technical results is that standard reasoning problems about actions (executability and projection), as well as the plan existence problem are decidable if one restricts the logic for describing action pre- and …
