Superconductivity In An Inhomogeneous Bundle Of Metallic And Semiconducting Nanotubes, Ilya Grigorenko, Anvar Zakhidov

Publications and Research

Using Bogoliubov-de Gennes formalism for inhomogeneous systems, we have studied superconducting properties of a bundle of packed carbon nanotubes, making a triangular lattice in the bundle's transverse cross-section. The bundle consists of a mixture of metallic and doped semiconducting nanotubes, which have different critical transition temperatures. We investigate how a spatially averaged superconducting order parameter and the critical transition temperature depend on the fraction of the doped semiconducting carbon nanotubes in the bundle. Our simulations suggest that the superconductivity in the bundle will be suppressed when the fraction of the doped semiconducting carbon nanotubes will be less than 0.5, which …

In this chapter he explores the relationship between question development, data collection, and crafting an answer to his research question. He de- scribes how his question developed while he developed his own set of “eth- nographic eyes” as a researcher and how he worked to settle on a question that …

Assessing Continuous Contamination Discharge From A Combined Sewer Outfall (Cso) Into A Tidal Wetland Creek: Bacteriological And Heavy Metals Indicators, Timothy Eaton, Gregory D. O'Mullan, Ashaki A. Rouff

Publications and Research

Continuous discharge from a combined sewer overflow (CSO) into a tidal wetland creek in the New York City urban area was analyzed to assess the extent of water quality degradation from fecal bacteria contamination during both dry and wet weather. A combination of fecal indicator bacteria (FIB), total suspended solids, and dissolved metals were used to infer the presence of sewage pollution from the CSO discharge and to constrain the spatial and temporal impact on water quality and dry season creek flows. Upstream of the CSO, creek flow was dominated by groundwater input, and FIB levels were very low or …

Centerline Extraction For Image Segmentation Using Gradient And Direction Vector Flow Active Contours, Shuqun Zhang, Jianyang Zhou

Publications and Research

In this paper, we propose a fast centerline extraction method to be used for gradient and direction vector flow of active contours. The gradient and direction vector flow is a recently reported active contour model capable of significantly improving the image segmentation performance especially for complex object shape, by seamlessly integrating gradient vector flow and prior directional information. Since the prior directional information is provided by manual line drawing, it can be inconvenient for inexperienced users who might have difficulty in finding the best place to draw the directional lines to achieve the best segmentation performance. This paper describes a …

Corticospinal Reorganization After Locomotor Training In A Person With Motor Incomplete Paraplegia, Nupur Hajela, Chaithanya K. Mummidisetty, Andrew C. Smith, Maria Knikou

Publications and Research

Activity-dependent plasticity as a result of reorganization of neural circuits is a fundamental characteristic of the central nervous system that occurs simultaneously in multiple sites. In this study, we established the effects of subthreshold transcranial magnetic stimulation (TMS) over the primary motor cortex region on the tibialis anterior (TA) long-latency flexion reflex. Neurophysiological tests were conducted before and after robotic gait training in one person with a motor incomplete spinal cord injury (SCI) while at rest and during robotic-assisted stepping. The TA flexion reflex was evoked following nonnociceptive sural nerve stimulation and was conditioned by TMS at 0.9 TA motor …

Frankly Speaking, "The Men That Is Now Is Only All Pallaver And What They Can Get Our Of You": Migration And White Slavery In Argentina In Joyce's "Eveline", M Laura Barberan Reinares

Publications and Research

This article analyzes James Joyce’s “Eveline” (1904), looking at the moral panic about “white slavery” in Europe and South America. The article especially focuses on Argentina, the foremost recipient of trafficked women between 1880 and 1930 (and, of course, Joyce’s destination choice for Eveline). By looking at Frank, the sailor who intends to take Eveline to Buenos Aires, this article explores the possible links between Joyce’s story and the sex trafficking industry thriving in Buenos Aires through the Jewish criminal association Zwi Migdal. Frank’s representation allows us to draw this connection because his behavior with Eveline coincides with the seduction …

The authors suggest …

The Role Of Video In Early Field Experiences, Laura H. Baecher, Shiao-Chuan Kung, Abigail M. Jewkes, Christine Rosalia

Publications and Research

The purpose of this investigation was to explore the influence of video models on teacher candidates' capacity to self-evaluate their teaching performance in early fieldwork. This was examined by providing video models along with evaluation rubrics that represented desired performance standard to one group of pre-service teacher candidates, while another group was provided the descriptions of these lessons and corresponding evaluation rubrics. Participants then video recorded their teaching and self-evaluated this performance. Results indicated that the introduction of video models reduced inflation of scores in self-evaluation and enhanced candidates' understanding of the expectations for the performance assessment of teaching.

Making Change Happen In The Middle (Approaches To Innovation For Library Middle Managers), Robert Farrell

Publications and Research

This paper seeks to provide library managers with a theoretical framework for thinking about how change is effected by those in middle management positions. Starting from the principles that change takes place within socio-culturally bounded contexts and is most successful when approached indirectly, two scenarios characteristic of many situations requiring change middle managers commonly face are then put forward. Following each scenario, a possible solution or path towards change is advanced in order to provide the reader with models for putting into practice the theoretical ideas presented. A methodology that combines theoretical frameworks and practical scenarios is adopted in order …

Landau-Zener Dynamics Of A Nanoresonator Containing A Tunneling Spin, Michael F. O'Keeffe, Eugene M. Chudnovsky, Dmitry A. Garanin

Publications and Research

We study the Landau-Zener dynamics of a tunneling spin coupled to a torsional resonator. For strong spin-phonon coupling, when the oscillator frequency is large compared to the tunnel splitting, the system exhibits multiple Landau-Zener transitions. Entanglement of spin and mechanical angular momentum results in abrupt changes of oscillator dynamics which coincide in time with spin transitions. We show that a large number of spins on a single oscillator coupled only through the in-phase phonon field behaves as a single large spin, greatly enhancing the spin-phonon coupling. We compare purely quantum and semiclassical dynamics of the system and discuss their experimental …

Quantum Dynamics Of Vortices In Mesoscopic Magnetic Disks, Ricardo Zarzuela, Eugene M. Chudnovsky, J M. Hernandez, J Tajeda

Publications and Research

Model of quantum depinning of magnetic vortex cores from line defects in a disk geometry and under the application of an in-plane magnetic field has been developed within the framework of the Caldeira-Leggett theory. The corresponding instanton solutions are computed for several values of the magnetic field. Expressions for the crossover temperature Tc and for the depinning rate \Gamma(T) are obtained. Fitting of the theory parameters to experimental data is also presented.

Reversal Of Magnetization Of A Single-Domain Magnetic Particle By The Ac Field Of Time-Dependent Frequency, Liufei Cai, Dmitry A. Garanin, Eugene M. Chudnovsky

Publications and Research

We report numerical and analytical studies of the reversal of the magnetic moment of a single- domain magnetic particle by a circularly polarized ac field of time-dependent frequency. For the time-linear frequency sweep, the phase diagrams are computed that illustrate the dependence of the reversal on the frequency sweep rate v , the amplitude of the ac field h , the magnetic anisotropy field d , and the damping parameter . It is shown that the most efficient magnetization reversal requires a non-linear time dependence of the frequency, ! ( t ) , for which an exact analytical formula is …

Excitation Modes Of Vortices In Submicron Magnetic Disks, Ricardo Zarzuela, Eugene M. Chudnovsky, Javier Tejada

Publications and Research

Classical and quantum theory of spin waves in the vortex state of a mesoscopic sub-micron magnetic disk has been developed with account of the finite mass density of the vortex. Oscillations of the vortex core resemble oscillations of a charged string in a potential well in the presence of the magnetic field. Conventional gyroscopic frequency appears as a gap in the spectrum of spin waves of the vortex. The mass of the vortex has been computed that agrees with experimental findings. Finite vortex mass generates a high-frequency branch of spin waves. Effects of the external magnetic field and dissipation have …

Turbulent Fronts Of Quantum Detonation In Molecular Magnets, Dmitry A. Garanin

Publications and Research

Dipolar-controlled quantum deflagration going over into quantum detonation in the elongated Mn_12 Ac molecular magnet in a strong transverse field has been considered within the full 3d model. It is shown that within the dipolar window around tunneling resonances the deflagration front is non-flat. With increasing bias, dipolar instability makes the front turbulent, while its speed reaches sonic values, that is a signature of detonation.

Black Hole Formation In Fuzzy Sphere Collapse, Norihiro Izuka, Daniel N. Kabat, Roy Shubho, Debajyoti Sarkar

Publications and Research

We study the collapse of a fuzzy sphere, that is a spherical membrane built out of D0-branes, in the BFSS model. At weak coupling, as the sphere shrinks, open strings are produced. If the initial radius is large then open string production is not important and the sphere behaves classically. At intermediate initial radius the back-reaction from open string production is important but the fuzzy sphere retains its identity. At small initial radius the sphere collapses to form a black hole. The crossover between the later two regimes is smooth and occurs at the correspondence point of Horowitz and Polchinski.
