1 Vardeny, Zeev ValentineCooperative and stimulated emission in poly(p-phenylene-vinylene) thin films and solutionsWe discuss cooperative and stimulated emissions and separate their respective contributions to the emission spectral narrowing in thin films and solutions of poly(p-phenylene-vinylene) derivatives. Whereas cooperative radiation is favored in films with poor optical confinement, directional stimula...pi-conjugated polymers; PPV; Spectral narrowing1998-04
2 DeTar, CarletonCritical behavior at the chiral phase transitionIt is generally expected that two-flavor QCD undergoes a high temperature chiral symmetry restoring phase transition at zero quark mass, with O(4) critical behavior[1]. Verifying this expectation is important for understanding the phenomenology of the transition and for facilitating an extrapolation...Phase transitions; Staggered fermions1998-04
3 Varner, Michael W.Elevated second-trimester maternal serum hCG: a marker of inadequate angiogenesis.OBJECTIVE: To measure angiogenin, a potent inducer of neovascularization and interleukin-6, as an indicator of acute inflammation, in second-trimester amniotic fluid of patients with elevated maternal serum hCG. METHODS: In this case-control study, 20 patients with elevated maternal serum hCG (at le...Angiogenesis Inducing Agents; Interleukin-6; Pregnancy Complications; hCG1998-04
4 DeTar, CarletonLight quark spectrum with improved gauge and fermion actionsWe report on a study of the light quark spectrum using an improved gauge action and both Kogut-Susskind and Naik quark actions. We have studied six different lattice spacings, corresponding to plaquette couplings ranging from 6.8 to 7.9, with five to six quark masses per coupling. We compare the t...Quark spectrum; Kogut-Susskind quarks; Naik quarks1998-04
5 Swallow, Charles E.; Tsuruda, Jay S.; Digre, Kathleen B.; Glaser, Matthew J.; Davidson, H. Christian; Harnsberger, H. RicTerson syndrome: CT evaluation in 12 patients.PURPOSE: Terson syndrome may be overlooked in the acute setting and often requires ophthalmologic intervention to prevent long-term visual loss. In this syndrome, vitreous or retinal hemorrhage results from an abrupt rise in intracranial pressure, leading to retinal venous hypertension and intraocul...Retinal Hemorrhage; Visual Acuity; Vitreous Hemorrhage1998-04
6 Wu, Yong-ShiThermal activation of quasiparticles and thermodynamics of fractional quantum Hall liquidsQuasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible state-counting schemes, involving different assumptions on statistical correlations. Thermal activ...Quasielectrons; Quasiholes; Exclusion statistics1998-04
7 DeTar, CarletonUpdate on the hadron spectrum with two flavors of staggered quarksWe present an update on the MILC Collaboration's light hadron spectrum calculation with two flavors of dynamical, staggered quarks. Results are presented for gauge couplings 5.30, 5.415, 5.50 and 5.60, with a range of quark masses for each value of the coupling. We present extrapolations of mN/mp ...Staggered quarks; Hadron spectrum1998-04
