An improvement on the Delsarte-type LP-bound with application to MUBs
The linear programming (LP) bound of Delsarte can be applied to several
problems in various branches of mathematics. We describe a general Fourier
analytic method to get a slight improvement on this bound. We then apply our
method to the problem of mutually unbiased bases (MUBs) to prove that the
Fourier family in dimension 6 cannot be extended to a full system of
MUBs.Comment: 10 page
Editing of EIA coded, numerically controlled, machine tool tapes
Editing of numerically controlled (N/C) machine tool tapes (8-level paper tape) using an interactive graphic display processor is described. A rapid technique required for correcting production errors in N/C tapes was developed using the interactive text editor on the IMLAC PDS-ID graphic display system and two special programs resident on disk. The correction technique and special programs for processing N/C tapes coded to EIA specifications are discussed
Input of the US Advisory Panel on Federal International Tax Reform
In November 2005, the U.S. President's Advisory Panel on Federal Tax Reform released a comprehensive Report titled “Simple, Fair, and Pro-Growth: Proposals to Fix America's Tax System.†The Report addressed all aspects of the federal income tax treatment of households and businesses under both domestic and international rules. This paper focuses on the proposals dealing with international elements of federal tax reform that affect multinational businesses. The report presents two broad Plans for improving the U.S. Internal Revenue Code in general and the international aspects of the Code in particular. The Simplified Income Tax (SIT) Plan recommends moving toward a territorial-based income tax system that would exempt active foreign-source business income of foreign branches and controlled foreign subsidiaries at the corporate level and would tax mobile foreign-source income. The Growth and Investment Tax (GIT) Plan recommends moving toward a consumption-based tax system that would tax U.S. businesses on total sales less certain inputs. To highlight the essential aspects dealing with the income tax, this paper will focus on the Simplified Income Tax Plan.U.S., federal tax reform, multinational businesses, territorial-based income tax system, foreign-source business income, subsidiaries, consumption-based tax system, Weiner
Comments on "Observation of Long-Range, Near-Side Angular Correlations in Proton-Proton Collisions at the LHC" by the CMS collaboration(arXiv:1009.4122v1 [hep-ex])"
It is the purpose of this note to point out that the CMS observation is in
line with previous observations in particle physics at large transverse momenta
and/or high multiplicities at lower energies, which were interpreted as
possible evidence for quark-gluon plasma (QGP), and to suggest other features
of the QGP observed in A+A collisions such as radial flow and jet quenching,
which should be investigated in p-p collisions in order to provide further
evidence for QGP production
Extending the Research on 1:1 Technology Integration in Middle Schools: A Call for Using Institutional Theory in Educational Technology Research
In this essay, we argue institutional lenses are a vital but largely missing part of understanding how 1:1 technology programs can effect change in teaching and learning in middle schools. Indeed, while current research highlights the positive effects technology integration efforts, and 1:1 programs in particular, have on student learning and engagement, much has focused on the knowledge, skills, and beliefs of individuals or groups of actors. There is less research considering how the institutional context may impact teacher and administrator behavior regarding these and other technology-focused efforts thus limiting our ability to fully support schools and teachers in these efforts. We conclude by calling on researchers to use institutional theory to further understand and support implementation efforts and enhance outcomes for schools, teachers, and students alike
