Vardeny, Zeev Valentine | Electromodulation of charge-transfer photoexcitations in pristine and C60-doped conjugated polymers | We study the effect of an electric field of up to 100 kV/cm on photoexcitations in pristine and C60-doped p-conjugated polymers by electromodulated photoinduced absorption (EPA). In EPA, we measure changes in the photoinduced absorption of a polymer film induced by an electric field. The dominant ... | Electromodulation; Charge-transfer photoexcitations; Photoinduced absorption; pi-conjugated polymers; Electromodulation spectroscopy | 1999-04 |

Eisenman, Patricia A. | Hormonal changes throughout the menstrual cycle and increased anterior cruciate ligament laxity in females | OBJECTIVE: To determine whether women experience significantly greater anterior cruciate ligament (ACL) laxity in conjunction with estrogen and progesterone surges during a normal 28- to 30-day menstrual cycle. DESIGN AND SETTING: Serial estrogen and progesterone levels were measured via radioimmuno... | Estrogen; Progesterone; Knee Arthrometer; Radioimmunoassay | 1999-04 |

Vardeny, Zeev Valentine | Photogeneration action spectroscopy of neutral and charged excitations in films of ladder-type poly(para-phenylene) | The photogeneration quantum efficiency action spectra of long-lived neutral and charged excitations in films of a ladder-type poly(para-phenylene) were measured. We found that both triplet and polaron action spectra show, in addition to a step function increase at the optical gap, a monotonic rise a... | Photogeneration; Neutral excitations; Charged excitations; pi-conjugated polymers; Transient spectroscopy | 1999-04 |
