101 Couldwell, William T.Man for all seasons: W.W. KeenWILLIAM WILLIAMS KEEN was the catalyst for the advent of neurosurgery in the United States. He served in the Civil War and collaborated with Silas Weir Mitchell in studying injuries sustained to the nervous system. These studies culminated in the publication in 1864 of Gunshot Wounds and Other Inj...Brain tumor2002
102 Dawson, KyleMasses of high-redshift clusters via SZ effect observationsWe present Sunyaev-Zel'dovich Effect (SZE) observations of distant, highly X-ray luminous clusters of galaxies. We use the SZE data to constrain their total masses, independent of X-ray observations. To do this, we assume the clusters have the same gas mass fraction as that derived from SZE measure...Sunyaev-Zel'dovich Effect; X-rays; Redshift2002
103 Mathews, V. John; Clark, Edward B.Mean frequency estimation of narrowband signals and its application to doppler ultrasound blood velocity waveform estimationABSTRACT Many applications involving Doppler signals require the accurate estimation of the power-weighted mean frequency over short durations of the signal due to it's nonstationarity. This paper presents a novel algorithm for estimating mean frequencies using the eigenstructure of the covariance ...2002
104 Beckerle, Mary C.Members of the zyxin family of LIM proteins interact with members of the p130cas family of signal transducersIntegrin binding to extracellular matrix proteins induces formation of signaling complexes at focal adhesions. Zyxin co-localizes with integrins at sites of cellsubstratum adhesion and is postulated to serve as a docking site for the assembly of multimeric protein complexes involved in regulating ce...Zyxin; Actin; LIM domains; Trip6; Focal adhesions2002
105 Capecchi, Mario R.Mice lacking endothelial angiotensin-converting enzyme have a normal blood pressureTo test the hypothesis that local vascular production of angiotensin II is necessary for the normal regulation of blood pressure, we engineered a new line of genetically altered mice that lack endothelial angiotensin-converting enzyme (ACE). This was accomplished using a novel strategy of targeted...2002
106 Olson, Randall J.Microphaco updateMicrophacoemulsification, or cataract surgery using ultrasound through two small stab incisions. Wound burn is now not a problem with AMO's Sovereign system plus Whitestar technology.Microphacoemulsification; Wound Burn; Cataract Extraction2002
107 Seger, JonModels of sex ratio evolutionOur understanding of sex ratio evolution depends strongly on models that identify: (1) constraints on the production of male and female offspring, and (2) fitness consequences entailed by the production of different attainable brood sex ratios. Verbal and mathematical arguments by, among others, D...Fitness; Species; Sex-allocation2002
108 Bedrov, Dmitro; Smith, Grant D.Molecular dynamics simulations of HMX crystal polymorphs using a flexible molecule force fieldMolecular dynamics simulations using a recently developed quantum chemistry-based atomistic force field [J. Phys. Chem. B 103 (1999) 3570] were performed in order to obtain unit cell parameters, coefficients of thermal expansion, and heats of sublimation for the three pure crystal polymorphs of octa...HMX; Crystal polymorphs; Force field; Coefficients of thermal expansion; Heat of sublimation; Cell parameters2002
109 Jones, Bryan W.Molecular phenotyping of retinal ganglion cellsClassifying all of the ganglion cells in the mammalian retina has long been a goal of anatomists, physiologists, and cell biologists. The rabbit retinal ganglion cell layer was phenotyped using intrinsic small molecule signals (aspartate, glutamate, glycine, glutamine, GABA, and taurine) and glutama...Aspartic Acid/metabolism; Image Cytometry/methods2002
110 Lupton, John MarkMolecular thermometer based on long-lived emission from platinum octaethyl porphyrinA highly sensitive molecular thermometer based on platinum octaethyl porphyrin, which can be employed in a range of environments, is presented. The thermal activation of the emission spectrum results in a change in emission intensity by an order of magnitude over a temperature range of 45 K about ro...Molecular thermometer; Platinum octaethyl porphyrin2002
111 Smith, Grant D.; Borodin, OlegMolecular-dynamics simulation study of dielectric relaxation in a 1,4-polybutadiene meltWe have carried out atomistic molecular dynamics simulations of a melt of 1,4-poly(butadiene) from temperatures well above the experimentally observed merging of the primary a process and secondary b process down to temperatures approaching the experimentally observed bifurcation temperature. The re...Polymer melts; 1,4-polybutadiene; Chain dynamics; Conformational dynamics2002

115 Vardeny, Zeev ValentineMultiple resonances in microdisk lasers of ∏-conjugated polymersWe have fabricated microdisk lasers from p-conjugated polymers that show multiline emission spectrum upon optical excitation. Using Fourier transform analysis, each emission line is assigned integer to an interger Bessel function that helps to estimate the field distribution inside the photoexcited ...Multiple resonances; Microdisks; Microdisk lasers; pi-conjugated polymers2002
116 Millgram, ElijahMurdoch, practical reasoning, and particularismParticularism is a contemporary movement in moral Philosophy; that it is hard to know what to do with. On the one hand, it's hard to dismiss. Its ranks include respectable - even prominent - authors such as Jonathan Dancy, Margaret Little, John McDowell, David McNaughton and Richard Norman.1 It purp...2002
117 National Medals of Science and Technology Awards (2001) Ceremony and Banquet, held June 13, 2002This 51 minutes, 5 seconds video is divided into two parts: the first part is a film introducing the award winners and their achievements; the second is the presentation of the actual awards by George W. Bush, President of the United States. Medal winners were: Mario R.

118 Fernandez, Diego P.Near-criticality in dilute binary mixtures: distribution of azulene between coexisting liquid and vapor carbon dioxideThe equilibrium distribution of dilute solutes between vapor and liquid coexisting phases of near-critical solvents exhibits a simple dependence on the solvent's liquid density which extends over a wide temperature range; however, theory predicts this dependence only as an asymptotic limit. In order...Near-critical solvents; Azulene; Binary mixtures; Dilute solutions2002
119 Drews, FrankNegative priming and stimulus repetition: a reply to Neill and JoordensNegative priming is reliably obtained with repeated items, but not with novel items. Here, we review why these stimulus repetition effects raise problems for memory based theories of negative priming. Furthermore, we provide empirical evidence casting doubt on Neill and Joordens's (2002) claimthat...Negative priming; Stimuli; Perception2002
