176 Vardeny, Zeev ValentineOptical absorption in the substituted phenylene-based conjugated polymers: theory and experimentWe investigate theoretically and experimentally the effects of (2,5) chemical substitution on the optical absorption in the phenylene-based conjugated polymers. Theoretically, substitution destroys both the charge-conjugation symmetry and spatial symmetry that characterize the unsubstituted materia...Phenylene-based conjugated polymers; Optical absorption; Chemical substitution; Coulomb correlated models1997-01
177 Gelfand, Donna M.Preschool assessment of attachment: construct validity in a sample of depressed and nondepressed families.Construct validity of the newly developed Preschool Assessment of Attachment (PAA) was examined in a sample of depressed and nondepressed mothers and their preschoolers, focusing on attachment related differences in children's general caregiving environments, maternal psychosocial functioning, and c...Preschoolers; Families; Maternal, psychosocial functioning; Mothers; Children, caregiving; Attachment1997-07

180 DeTar, CarletonRecent MILC spectrum results*We report on results from three spectrum calculations with staggered quarks: 1) a quenched calculation with the standard action for the gluons and quarks; 2) a quenched calculation with improved actions for both the gluons and quarks; and 3) a calculation with two flavors of dynamical quarks using...Staggered quarks; Hadron spectrum1997-02
181 Vardeny, Zeev ValentineRing microlasers from conducting polymersWe demonstrate pulsed, photopumped multimode laser emission in the visible spectral range from cylindrical microcavities formed by conducting polymer thin films deposited around optical fibers. The laser is characterized by narrow emission lines (~1.5 cm-1), a well-defined excitation threshold, an...Ring microlasers; Laser emission; Waveguided ring modes; Whispering gallery modes1997-08
182 Varner, Michael W.; Porter T. FlintRisk of preterm birth across generations.OBJECTIVE: To examine the risk of preterm birth for mothers who themselves were born before term. METHODS: Data were taken from a linked data base of birth certificates composed of two cohorts: 1) a parental cohort of women born between 1947 and 1957 and 2) their offspring born between 1970 and 1992...Preterm mothers; Pregnancy; Premature; Risk1997-07
183 Vardeny, Zeev ValentineSpin and spectral signatures of polaron pairs in ∏-conjugated polymersWe have studied polaron pair photoexcitations in a variety of p-conjugated polymer films by photoinduced absorption (PA) and optically detected magnetic resonance (ODMR). Both luminescent and nonluminescent polymers have been studied. An exchange interaction between polarons broadens their magneti...Spin signatures; spectral signatures; Photoinduced absorption; Photoexcitation1997-08
184 DeTar, CarletonThermodynamics for two flavor QCD*We conclude our analysis of the Nt = 6 equation of state (EOS) for two flavor QCD, first described at last year's conference. We have obtained new runs at amq = 0.025 and improved runs at amq = 0.0125. The results are extrapolated to mq = 0, and we extract the speed of sound as well. We also present...Phase transitions; Quark-gluon plasma; Chiral symmetry1997-02
185 Vardeny, Zeev ValentineTransient spectroscopy of Frenkel and charge transfer excitons in α-sexithienyl filmsPhotoexcitations dynamics are investigated in a-sexithienyl nanocrystalline films using transient photomodulation in a spectral range from 0.4 to 2.5 eV and time domain from 200 fs to 50 ms. We identify intrachain and interchain excitations. The former are even parity excitons with ultrafast dynami...Transient spectroscopy; Excitons; Frenkel exciton; Charge transfer exciton; Transient photomodulation1997-10
186 Gerton, JordanTriplet s-wave resonance in 6Li collisions and scattering lengths of 6Li and 7LiThe triplet s-wave scattering length of 6Li is determined using two-photon photoassociative spectroscopy of the diatomic α 3Σu+ state of 6Li2. The measured binding energy of the highest-lying bound state, combined with knowledge of the potential, determines the s-wave scattering length to be -21...1997-05
187 DeTar, CarletonUpdate on fBWe describe the current status of the MILC collaboration computation of fB, fBs , fD, fDs and their ratios. Progress over the past year includes: better statistics and plateaus at _x000C_β = 6.52 (quenched), β_x000C_ = 5.6 (NF = 2) and β_x000C_ = 5.445 (NF = 2), new runs with a wide range of dyn...Decay constants; Wilson quarks1997-02
188 DeTar, CarletonWhich chiral symmetry is restored in high temperature quantum chromodynamics?Sigma models for the high temperature phase transition in quantum chromodynamics suggest that at high temperature the SU(Nf) X 3 SU(Nf) chiral symmetry becomes exact, but the anomalous axial U(1) symmetry need not be restored. In numerical lattice simulations, traditional methods for detecting symme...Chiral symmetry; Staggered fermions; Phase transitions1997-01
189 Paiva, Marie96-97 Final report: ALA/USIA library fellow to ethiopiaThe National Library of Ethiopia (NLE) in Addis Ababa requested a librarian to help with staff training, evaluate organizational procedures and processes, and make recommendations to the institution.

190 Regehr, JohnAn isotach implementation for myrinetAn isotach network provides strong guarantees about message delivery order. We show that an isotach network can be implemented efficiently entirely in software, using commercial o-the-shelf hardware. This report describes that effort. Parts of this implementation could be performed much more efficie...1997-01-01
191 Capecchi, Mario R.Cleft palate in mice with a targeted mutation in the gamma-aminobutyric acid-producing enzyme glutamic acid decarboxylase 67.The functions of neurotransmitters in fetal development are poorly understood. Genetic observations have suggested a role for the inhibitory amino acid neurotransmitter gamma-aminobutyric acid (GABA) in the normal development of the mouse palate. Mice homozygous for mutations in the beta-3 GABAA rec...Animals, Newborn; Crosses, Genetic1997-10-14
192 Capecchi, Mario R.Critical role of tissue angiotensin-converting enzyme as revealed by gene targeting in miceAngiotensin-converting enzyme (ACE) generates the vasoconstrictor angiotensin II, which plays a critical role in maintenance of blood pressure in mammals. Although significant ACE activity is found in plasma, the majority of the enzyme is bound to tissues such as the vascular endothelium. We used ta...Blood pressure; ACE activity; Enzyme1997-03-06
