Combustion Synthesis and Characterization of Bulk Nanocrystalline ${\bf Fe}_{\bf 88} {\bf Si}_{\bf 12}$ Alloy

IEEE Transactions on Nanotechnology, 2010
Bulk nanocrystalline Fe88Si12 alloy is fabricated by a combustion synthesis processing that is convenient, low in cost, and capable of being scaled up. The Fe88Si12 alloy consists of two phases: ?-Fe(Si) and Fe3Si. It is a composite structure of meshwork dispersed in a matrix.

BF AND ANTI-BF THEORIES IN THE GENERALIZED CONNECTION FORMALISM

Modern Physics Letters A, 2004
We present a generalized connection formalism to explicitly determine an off-shell BRST–anti-BRST algebra for BF theories. This results in the construction of anti-BF theories based on an anti-BRST exact quantum action. These are not fundamentally different from BF theories, since they are in complete duality with respect to a mirror symmetry of the ...

The front cover artwork was done by Michelle Farrelly, a member of the Martin group at Monash University. The image represents a perspective of a cuvette in which the catalysis of the thiosulfate-ferricyanide reaction was achieved by a TCNQF4 -based redox reaction in aqueous solution.

Aggregation of [Cu${{\bf }{{{\bf II}\hfill \atop \bf 4\hfill}}}$] Building Blocks into [Cu${{\bf }{{{\bf II}\hfill \atop \bf 8\hfill}}}$] Clusters or a [Cu${{\bf }{{{\bf II}\hfill \atop \bf 4\hfill}}}$]_∞ Chain through Subtle Chemical Control

Chemistry – A European Journal, 2004
AbstractCoordination complexes of the ligand H3L [1,3‐bis(3‐oxo‐3‐phenylpropionyl)‐2‐hydroxy‐5‐methylbenzene] with CuII are reported. Clusters showing various nuclearities or modes of supramolecular organization have been prepared by slightly changing the reaction conditions and have been crystallographically characterized. The reaction of H3L with one

Distributed BFS algorithms

26th Annual Symposium on Foundations of Computer Science (sfcs 1985), 1985
This paper develops a new distributed BFS algorithm for an asynchronous communication network. This paper presents two new BFS algorithms with improved communication complexity. The first algorithm has complexity O((E+V1.5)?logV) in communication and O(V1.5?logV) in time. The second algorithm uses the technique of the first recursively and achieves O(E?

The Polynomial Degree of the Grassmannian $${\mathcal G_{\bf 1,}{\bf n,}{\bf 2}}$$

Designs, Codes and Cryptography, 2006
For a subset ? of PG(N, 2) a known result states that ? has polynomial degree ? r, r? N, if and only if ? intersects every r-flat of PG(N, 2) in an odd number of points. Certain refinements of this result are considered, and are then applied in the case when ?

A NEW FAST VARIANT (BF*F08) OF THE BF POLYMORPHISM

International Journal of Immunogenetics, 1982
SUMMARYA new variant in the BF polymorphism was found in one individual from an isolate (Dogons) of Mali. It might correspond to the expression of a new allele BF*F08 with haemolytic activity.

On simplicial BF theory

Doklady Mathematics, 2008
This paper is a short summary of the author's constructions and results in [``Notes on simplicial \(BF\) theory'', \url{arXiv:hep-th/0610326v3}], which were later extended in his Ph. D. thesis [``Discrete \(BF\) theory'', \url{arXiv:0809.1160v2}], and may serve as an introduction or as a guide to these works. The author's results fit into the framework

Modules M such that ${\rm {\bf Ext}}_{{\bf \textit{R}}}^{\bf{1}}{({\bf \textit{M}},-)}$ Commutes with Direct Limits

Algebras and Representation Theory, 2012
We will use Watts’s theorem together with Lenzing’s characterization of finitely presented modules via commuting properties of the induced tensor functor in order to study commuting properties of covariant Ext-functors.
