102 Vardeny, Zeev ValentineStimulated emission in high-gain organic mediaStimulated emission was studied in various scattering gain media, including thin p-conjugated polymer films, organic dyes-doped gel films, and opal crystals saturated with polymer and laser dye solutions. We found that at high excitation intensities a featureless amplified spontaneous emission ban...Stimulated emission; High-gain organic media; pi-conjugated polymers; Scattering gain media; Organic dyes-doped gel films; Opal crystals1999-02
103 Vardeny, Zeev ValentineUltrafast spectroscopy of even-parity states in ∏-conjugated polymersRelaxation dynamics of even parity (Ag) states in poly(p-phenylene vinylene) derivatives are studied using a novel fsec transient spectroscopy, in which two different excitation pulses successively generate odd parity (1 1Bµ) excitons at 2.2 eV and then reexcite them to higher Ag states. For reexci...pi-conjugated polymers; Ultrafast spectroscopy; PPV; Relaxation dynamics2000-09
104 Narus, Scott P.A domain analysis model for eIRB systems: addressing the weak link in clinical research informaticsInstitutional Review Boards (IRBs) are a critical component of clinical research and can become a significant bottleneck due to the dramatic increase, in both volume and complexity of clinical research.

105 Riloff, Ellen M.Learning and evaluating the content and structure of a term taxonomyIn this paper, we describe a weakly supervised bootstrapping algorithm that reads Web texts and learns taxonomy terms. The bootstrapping algorithm starts with two seed words (a seed hypernym (Root concept) and a seed hyponym) that are inserted into a doubly anchored hyponym pattern. In alternatin...Weakly supervised; Bootstrapping algorithm; Seed hypernym; Seed hyponym; Root concept; Term taxonomy; Learning by reading systems2009
106 Sekercioglu, CaganMeasuring the meltdown: drivers of global amphibian extinction and declineHabitat loss, climate change, over-exploitation, disease and other factors have been hypothesised in the global decline of amphibian biodiversity. However, the relative importance of and synergies among different drivers are still poorly understood. We present the largest global analysis of roughly ...2008-01-01
107 Harrison, Reid R.Micropower circuits for bidirectional wireless telemetry in neural recording applicationsState-of-the art neural recording systems require electronics allowing for transcutaneous, bidirectional data transfer. As these circuits will be implanted near the brain, they must be small and low power. We have developed micropower integrated circuits for recovering clock and data signals over ...Micropower circuits; Neural recording systems; Low-power CMOS circuits, RF telemetry; Transcutaneous data link; Transmitter2005-01-01
108 Blumenthal, Donald K.; Underwood, Clayton J.Adaptation of the protein kinase filter paper assay to a 96-well microtiter format.The most widely used method for assaying protein kinase activities involves incorporation of radioactive phosphate into a protein or peptide substrate with subsequent binding or precipitaion of the radiolabeled substrate onto filter paper squares. We have adapted this assay for use with readily avai...Protein Kinase Activities; Filter Papers; Radioactive Phosphate1999-02-01
109 Mishchenko, EugeneFull counting statistics of a charge pump in the Coulomb blockade regimeWe study full charge counting statistics (FCCS) of a charge pump based on a nearly open single electron transistor. The problem is mapped onto an exactly soluble problem of a nonequilibrium g=1/2 Luttinger liquid with an impurity. We obtain an analytic expression for the generating function of the...Counting statistics; Luttinger liquid2001-11
110 Schmidt, Meic H.NASA light-emitting diode medical program-progress in space flight and terrestrial applicationsThis work is supported and managed through the NASA Marshall Space Flight Center - SBIR Program. Studies on cells exposed to microgravity and hypergravity indicate that human cells need gravity to stimulate cell growth. As the gravitational force increases or decreases, the cell function responds in...Terrestrial applications; Cell growth; NASA; Microgravity environment2000
111 Lupton, John MarkRoom-temperature exciton storage in elongated semiconductor nanocrystalsThe excited state of colloidal nanoheterostructures consisting of a spherical CdSe nanocrystal with an epitaxially attached CdS rod can be perturbed effectively by electric fields. Field-induced fluorescence quenching coincides with a conversion of the excited state species from the bright exciton ...Exciton storage; Colloidal nanoheterostructures; CdSe nanocrystal2007-01
112 Tasdizen, TolgaWatershed merge forest classification for electron microscopy image stack segmentationAutomated electron microscopy (EM) image analysis techniques can be tremendously helpful for connectomics research. In this paper, we extend our previous work [1] and propose a fully automatic method to utilize inter-section information for intra-section neuron segmentation of EM image stacks. A wat...2013-01-01
113 Clayton, Dale H.Ecological basis of coevolutionary historyMacroevolutionary patterns are difficult to interpret because they are the product of a time scale so vast that deterministic and chance events are hard to distinguish. Although the macroevolutionary history of a group can be reconstructed from extant species, determining the ecological context in ...2003
114 Sperry, John S.Evolution of water transport and xylem structureLand plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. The water-for-carbon exchange rate is poor, and evolutionary history indicates a progression of innovations for cheap water transport--beginning in order with capillary sucti...Cavitation; Vessels; Plants2003

122 Clayton, Dale H.Coevolutionary history of ecological replicates: comparing phylogenies of wing and body lice to Columbiform hostsPhylogenies depict the history of speciation for groups of organisms. Comparing the phylogenies of interacting groups can reveal instances of tandem speciation, or "cospeciation" (Brooks and McLennan, 1991; Hoberg et al., 1997; Paterson and Gray, 1997). Understanding the conditions under which cosp...Feather lice; Wing lice; Body lice; Cospeciation2003
