News release announces that ethnomusicologist Mac H. Brandt will discuss Latin American music in its sociocultural context in a lecture

Nebraska Extension educators bring entrepreneurship education to Georgia and Armenia

In a unique initiative by the American Councils for International Education, Nebraska Extension educators Molly Brandt and Marilyn Schlake were invited to travel to the countries of Georgia and Armenia in 2022 to train local educators in the principles of the 4-H Entrepreneurship Investigation (ESI) curriculum. Brandt, an innovation and entrepreneurship 4-H educator, and Schlake, a Rural Prosperity Nebraska educator in the Department of Agricultural Economics, prepared for what they thought was a one-time experience. However, after their successful endeavor in Tbilisi, Georgia, in October 2022, they were invited back in April 2023, to deliver similar training in Yerevan, Armenia

Tensor Constructions of Open String Theories II: Vector bundles, D-branes and orientifold groups

A generalized Chan-Paton construction is presented which is analogous to the tensor product of vector bundles. To this end open string theories are considered where the space of states decomposes into sectors whose product is described by a semigroup. The cyclicity properties of the open string theory are used to prove that the relevant semigroups are direct unions of Brandt semigroups. The known classification of Brandt semigroups then implies that all such theories have the structure of a theory with Dirichlet-branes. We also describe the structure of an arbitrary orientifold group, and show that the truncation to the invariant subspace defines a consistent open string theory. Finally, we analyze the possible orientifold projections of a theory with several kinds of branes.Comment: 11 pages, LaTe

Orientation Dependence of a Dislocation Etch for Zinc

The dislocation etch for (101-[bar]0] surfaces of zinc reported by Brandt, Adams, and Vreeland have been further explored. Additional surface orientations have been found where dislocation etching takes place. These orientations cover an area located between 3 degrees and 12.2 degrees to the [0001], and the area is symmetric about that axis. Attempts to produce dislocation etching on within 2 degrees of (0001) were generally unsuccessful. This is in contrast to etching of many crystals which takes place only within a few degrees of a low index plane

Expanded Quantum Cryptographic Entangling Probe

The paper [Howard E. Brandt, "Quantum Cryptographic Entangling Probe," Phys. Rev. A 71, 042312 (2005)] is generalized to include the full range of error rates for the projectively measured quantum cryptographic entangling probe.Comment: 4 page

High-order discontinuous Galerkin method for elastohydrodynamic lubrication line contact problems

In this paper a high-order discontinuous Galerkin method is used to solve steady-state isothermal line contact elastohydrodynamic lubrication problems. This method is found to be stable across a wide range of loads and is shown to permit accurate solutions using just a small number of degrees of freedom provided suitable grids are used. A comparison is made between results obtained using this proposed method and those from a very large finite difference calculation in order to demonstrate excellent accuracy for a typical highly loaded test problem
