1 DeTar, CarletonChiral logs with staggered fermionsWe compute chiral logarithms in the presence of "taste" symmetry breaking of staggered fermions. The lagrangian of Lee and Sharpe is generalized and then used to calculate the logs in π and K masses. We correct an error in Ref. [1]; the issue turns out to have implications for the comparison with ...Staggered fermions; Chiral logs2003-05
2 Olson, Randall J.Clinical comparison of single-piece and three-piece truncated hydrophobic acrylic intraocular lensesPURPOSE: To determine the clinical differences between three-piece (3P) and single-piece (SP) truncated hydrophobic acrylic intraocular lenses (IOL). DESIGN: Retrospective cohort clinical study. METHODS: The setting was an academic clinical practice. The patient population consisted of subjects with...Lenses, Intraocular; Patient Satisfaction; Postoperative Complications; Prosthesis Design; Visual Acuity2003-10
3 Olson, Randall J.Efficacy and wound-temperature gradient of WhiteStar technology phacoemulsification through a 1.2 mm incisionPURPOSE: To evaluate the efficacy and wound-temperature gradients of WhiteStar micropulse technology using bimanual phacoemulsification without an irrigation sleeve through a 1.2 mm incision. SETTING: Island Eye Surgicenter, Carle Place, New York, USA. METHODS: Ten patients had bimanual phacoemulsif...Endothelium, Corneal; Surgical Procedures; Lens Implantation; Wound Temperature gradient2003-06
4 DeTar, CarletonExotic hybrid mesons from improved Kogut-Susskind fermionsWe summarize our measurement of the mass of the exotic 1−+ hybrid meson using an improved Kogut-Susskind action. We show results from both quenched and dynamical quark simulations and compare with results from Wilson quarks. Extrapolation of these results to the physical quark mass allows compar...Chromomagnetic field; Kogut-Susskind fermions; Wilson quarks2003-05
5 Vardeny, Zeev ValentineFabrication and properties of gallium metallic photonic crystalsGallium metallic photonic crystals with 100% filling factor have been fabricated via infiltration of liquid gallium into opals of 300-nm silica spheres using a novel high pressure-high temperature technique. The electrical resistance of the Ga-opal crystals was measured at temperatures from 10 to 2...2003-10
6 DeTar, CarletonHeavy-light meson decay constants with N f = 3During the past year the MILC Collaboration has continued its study of heavy-light meson decay constants with three dynamical quarks. Calculations have been extended to a second lattice spacing of about 0.09 fm. At this lattice spacing, there are results in the quenched approximation and for thr...Dynamical quarks2003-05
7 DeTar, CarletonLight hadron properties with improved staggered quarksPreliminary results from simulations with 2+1 dynamical quark flavors at a lattice spacing of 0.09 fm are combined with earlier results at a = 0.13 fm. We examine the approach to the continuum limit and investigate the dependence of the pseudoscalar masses and decay constants as the sea and valence...Staggered quarks2003-05
8 Wu, Yong-ShiQuiver mechanics for deconstructed matrix stringIn this paper we propose a quiver model of matrix quantum mechanics with 8 supercharges which, on a Higgs branch, deconstructs the worldsheet of Matrix String Theory. This discrete model evades the fermion doubling problem and, in the continuum limit, enhances the number of supersymmetries to sixte...2003-12
9 DeTar, CarletonStatic hybrid quarkonium potential with improved staggered quarksWe are studying the effects of light dynamical quarks on the excitation energies of a flux tube between a static quark and antiquark. We report preliminary results of an analysis of the ground state potential and the ∑g′+ and Πu potentials. We have measured these potentials on closely matched...Quarkonium; Staggered quarks; Flux tube2003-05
10 DeTar, CarletonTopological susceptibility with the improved Asqtad actionAs a test of the chiral properties of the improved Asqtad (staggered fermion) action, we have been measuring the topological susceptibility as a function of quark masses for 2 + 1 dynamical flavors. We report preliminary results, which show reasonable agreement with leading order chiral perturbatio...Topological cbarge; Staggered fermions2003-05
11 Gerig, GuidoObject models in multiscale intrinsic coordinates via m-repsObject descriptions used for 3D segmentation by deformable models and for statistical characterization of 3D object classes benefit from having intrinsic correspondences over deformation of the objects or multiple instances in the same object class. These correspondences apply over a variety of spat...2003-01-01
12 Capecchi, Mario R.Xanthine oxidoreductase is central to the evolution and function of the innate immune system.The housekeeping enzyme xanthine oxidoreductase (XOR) has been studied intensively over the past 100 years, yet the complexity of its in vivo function is still poorly understood. A large body of literature focuses on the different catalyltic forms of XOR and their importance in the synthesis of reac...Animals; Gene Expression Regulation, Enzymologic; Humans; Immune System; Models, Biological2003-09-01
