Anti-B-B Mixing Constrains Topcolor-Assisted Technicolor

We argue that extended technicolor augmented with topcolor requires that all mixing between the third and the first two quark generations resides in the mixing matrix of left-handed down quarks. Then, the anti-B_d--B_d mixing that occurs in topcolor models constrains the coloron and Z' boson masses to be greater than about 5 TeV. This implies fine tuning of the topcolor couplings to better than 1%.Comment: 9 pages, LaTeX, with one postscript figure. Version to appear in Physics Letters B.

Timing disownership experiences in the rubber hand illusion

Some investigators of the rubber hand illusion (RHI) have suggested that when standard RHI induction procedures are employed, if the rubber hand is experienced by participants as owned, their corresponding biological hands are experienced as disowned. Others have demurred: drawing upon a variety of experimental data and conceptual considerations, they infer that experience of the RHI might include the experience of a supernumerary limb, but that experienced disownership of biological hands does not occur. Indeed, some investigators even categorically deny that any experimental paradigm has been employed or any evidence can be adduced to support the claim that disownership experiences occur during the RHI. It goes without saying that RHI experiences can be elusive, and that there is some evidence to support claims that supernumerary limb experiences can sometimes occur. Here, however, we test the claim that the conscious experience of disownership can occur during the RHI. In order to test this claim, we developed two new online proxies—onset time for the illusion and illusion duration—and combined these with established questionnaires that concern the conscious contents of the RHI, in particular ownership/disownership experiences. Both online proxy data and post hoc questionnaire data converge in supporting the claim that disownership experiences do occur, at least when the left hand is the object of investigation. Our findings that onset time and illusion duration are reliable measures suggest that investigations of the RHI stand to benefit by devoting more attention to data collected while the RHI is being experienced, in particular data concerning temporal dynamics

Progress on symmetry breaking and generational mixing in topcolor-assisted technicolor

Topcolor-assisted technicolor provides a dynamical explanation for electroweak and flavor symmetry breaking and for the large mass of the top quark without unnatural fine tuning. I briefly review the basics of topcolor-assisted technicolor, including major constraints and a general approach to satisfying them. The main challenge to topcolor-assisted technicolor is to generate the observed mixing between heavy and light generations while breaking the strong topcolor interactions near 1 TeV. I argue that these phenomena, as well as electroweak symmetry breaking, are intimately connected and I present a scenario for them based on nontrivial patterns of technifermion condensation. I also exhibit a class of models realizing this scenario.First author draf

Technihadron production and decay in low-scale technicolor

We discuss the production and decay rates of the lightest colorsinglet technihadrons, spin-one ρT and ωT and spin-zero πT , in a minimal “straw-man” model of low-scale techicolor. The revised ρT and ωT decay rates affect the technicolor searches planned for Run II of the Tevatron Collider.Accepted manuscrip

Adaptive Designs for Optimal Observed Fisher Information

Expected Fisher information can be found a priori and as a result its inverse is the primary variance approximation used in the design of experiments. This is in contrast to the common claim that the inverse of observed Fisher information is a better approximation to the variance of the maximum likelihood estimator. Observed Fisher information cannot be known a priori; however, if an experiment is conducted sequentially (in a series of runs) the observed Fisher information from previous runs is available. In the current work two adaptive designs are proposed that use the observed Fisher information from previous runs in the design of the current run.Comment: 19 pages, 2 figure

A completely integrable system on G2G_2 coadjoint orbits

We construct a Gelfand-Zeitlin system on a one-parameter family of $G_2$ coadjoint orbits that are multiplicity-free Hamiltonian $SU(3)$-spaces. Using this system we prove a lower bound for the Gromov width of these orbits. This lower bound agrees with the known upper bound.Comment: 7 pages, 2 figures. Comments are welcome

New Model-Independent Limit on Muon Substructure

If the discrepancy between the theoretical and newly measured values of the muon's anomalous magnetic moment is ascribed to muon substructure, there results an improved model--independent limit on its energy scale, 1.2 TeV < Lambda_mu < 3.2 TeV at 95% C.L.Comment: 3 pages, Latex. Revised version places 95% C.L. limits on muon substructure scale. Abstract is modified to reflect this chang

Voices from the Past: compositional approaches to using recorded speech

This paper investigates some of the ways in which composers and sound artists have used recordings of speech, especially in works mediated by technology. It will consider this within a wider context of spoken word, text composition and performance-based genres such as sound poetry. It will attempt to categorise some of the compositional techniques that may be used to work with speech, make specific reference to archive and oral history material and attempt to draw some conclusions

Sisters of St John of God in the Kimberley: A Journey Near Completion and A Story Still to be Told

The Sisters of St John of God (SSJG) arrived in the Kimberley in 1907 and through the following 110 years played a critical role in the story of the region: when it comes to health, education, and social development in the Kimberley over the past century the SSJG are central characters. As with many other institutions, the SSJG have reached a time in their journey where they are seeking to transition their values and experiences into some lasting benefit for the Kimberley and its people. It may be that the Sisters will no longer have a physical presence in this part of Australia but they are determined that their story will, in whatever way possible, provide some understanding to future generations of a part of the country whose colonial history bears so little resemblance to that of any other part of Australia.https://researchonline.nd.edu.au/nulungu_insights/1001/thumbnail.jp
