Major plant and diagnostic developments on MAST have enabled important advances in support of ITER, definition of a component test facility (CTF) and the clarification of underlying tokamak physics. For example, L-H transition studies benefit from high spatial and temporal resolution measurements of pedestal profile evolution (temperature, density and radial electric field) and in support of pe...
Cyber security education and outreach is a national priority. It is critical to encourage high school students to pursue studies in cyber security and related fields. High school outreach is a fundamental component of a cohesive cyber security education program. Most high school outreach programs in cyber security focus on short-term events such as a capture the flag contest or the CyberPatriot...
Physical schemas are representations of simple physically grounded relationships and interactions such as \move," \push," and \contain." We believe they are the conceptual primitives an agent employs to understand its environment. Physical schemas can be used at varying levels of abstraction across a variety of domains. We have designed a domain-general agent simulation and control testbed base...
We extend Witt’s theorem to several kinds of simultaneous isometries of subspaces. We determine sufficient and necessary conditions for the extension of an isometry of subspaces φ : E → E′ to an isometry φV : V → V ′ that also sends a given subspace to another, or a given self-dual flag to another, or a Witt’s decomposition to another and a special self-dual flag to another. We also determine s...
We present examples of flag homology spheres whose γvectors satisfy the Kruskal-Katona inequalities. This includes several families of well-studied simplicial complexes, including Coxeter complexes and the simplicial complexes dual to the associahedron and to the cyclohedron. In another direction, we show that if a flag (d− 1)-sphere has at most 2d + 2 vertices its γ-vector satisfies the Kruska...
This paper describes a new, high-speed contourf i l l method for alpha-numeric and Japanese Kanji characters developed to generate digital bitmap image (binary image) patterns from contour lines. The contour lines are expressed by Freeman's chain code. We call this method the Improved Edge-flag method. The speed of this method is increased by using an edge-flag list which stores the coordinates...
A recent experiment has shown “inverted drafting” in flags: the drag force on one flag is increased by excitation from the wake of another. Here we use vortex sheet simulations to show that inverted drafting occurs when the flag wakes add coherently to form strong vortices. By contrast, normal drafting occurs for higher-frequency oscillations, when the vortex wake becomes more complex and mixed...
A simplicial complex ∆ is called flag if all minimal nonfaces of ∆ have at most two elements. The following are proved: First, if ∆ is a flag simplicial pseudomanifold of dimension d− 1, then the graph of ∆ (i) is (2d−2)-vertex-connected and (ii) has a subgraph which is a subdivision of the graph of the d-dimensional cross-polytope. Second, the h-vector of a flag simplicial homology sphere ∆ of...
Fiber Recruiting (FiRe) peptides are described. These are derivatives of self-assembling fiber (SAF) forming peptides that are conjugated with small molecules (in our case, biotin or a FLAG-tag octapeptide). The FiRe peptides are co-assembled into fibers and used as bait to recruit folded and functional proteins to the fiber surfaces. This was demonstrated using two molecular recognition models...
in this paper, we are going to study the g-natural metrics on the tangent bundle of finslermanifolds. we concentrate on the complex and kählerian and hermitian structures associated with finslermanifolds via g-natural metrics. we prove that the almost complex structure induced by this metric is acomplex structure on tangent bundle if and only if the finsler metric is of scalar flag curvature. t...
