On The TimeResolved Optogalvanic Spectra Of Neon And Krypton, Naveed Piracha, K. Nesbett, S. Moten, P. Moeller
Naveed K. Piracha
In this work time resolved optogalvanic signals associated with transitions excited from the first metastable state of neon and krypton have been studied. These gases have similar energy state configurations and it is of significant interest to study their time resolved optogalvanic waveforms resulting from transitions belonging to the states of same quantum numbers. The experimentally observed optogalvanic signals recorded for different discharge currents have been fitted to a theoretical model to obtain parameters that determine amplitudes, instrumental time constants and decay rates of the 1s levels.

A novel technique has been developed to build vessels for liquid xenon ionization detectors entirely out of an ultraclean fluoropolymer. One such detector was operated inside a welded, He leak tight, allfluoropolymer chamber. The measured energy resolution for 570 keV gamma rays is σ/E=5.1% at a drift field of 1.5 kV/cm, in line with the best values obtained for ionization only detectors run in LXe using conventional, metal vessels.
Spin Effects In The Effective Quantum Field Theory Of General Relativity, A Ross, Br Holstein
Spin Effects In The Effective Quantum Field Theory Of General Relativity, A Ross, Br Holstein
Barry R Holstein
The calculation of gravitational scattering of particles with various spin configurations in the framework of effective quantum field theory of general relativity is presented. We find that the longrange quantum and classical corrections to the spinindependent piece and the spin–orbit coupling piece of the scattering amplitude and the scattering potential are universal for different spin configurations, which leads us to propose this universality to be true for arbitrary spins. Furthermore, we give the leading corrections to the spin–spin coupling, and a comparison with scattering in QED is made.

A Role For Huntingtin In Dynein/DynactinMediated Vesicle Trafficking, Jennifer Ross, Juliane P. Caviston, Sheila M. Antony, Mariko Tokito, Erika L.F Holzbaur
Jennifer Ross
Cytoplasmic dynein is a multisubunit microtubule motor complex that, together with its activator, dynactin, drives vesicular cargo toward the minus ends of microtubules. Huntingtin (Htt) is a vesicleassociated protein found in both neuronal and nonneuronal cells that is thought to be involved in vesicular transport. In this study, we demonstrate through yeast twohybrid and affinity chromatography assays that Htt and dynein intermediate chain interact directly; endogenous Htt and dynein coimmunoprecipitate from mouse brain cytosol. Htt RNAi in HeLa cells results in Golgi disruption, similar to the effects of compromising dynein/dynactin function. In vitro studies reveal that Htt and dynein ...

Nematic liquid crystal (LC) elastomers and gels have a rubbery polymer network coupled to the nematic director. While LC elastomers show a single, non hydrodynamic relaxation mode, dynamic light scattering studies of self assembled liquid crystal gels reveal orientational fluctuations that relax over a broad time scale. At short times, the relaxation dynamics exhibit hydrodynamic behavior. In contrast, the relaxation dynamics at long times are nonhydrodynamic, highly anisotropic, and increase in amplitude at small scattering angles. We argue that the slower dynamics arise from coupling between the director and the physically associated network, which prevents director orientational fluctuations from decaying ...
Parametrization Dependence Of The EnergyMomentum Tensor And The Metric, Nej BjerrumBohr, Jf Donoghue, Br Holstein
Parametrization Dependence Of The EnergyMomentum Tensor And The Metric, Nej BjerrumBohr, Jf Donoghue, Br Holstein
Barry R Holstein
We use results by Kirilin to comment that in general relativity the nonleading terms in the energymomentum tensor of a particle depends on the parameterization of the gravitational field. The classical observables are parameterization independent after a change in coordinates. The quantum effects that emerge within the same calculation of the metric also depend on the parameterization and a full quantum calculation requires the inclusion of further diagrams. However, within a given parameterization the quantum effects calculated by us in a previous paper are well defined. Flaws of Kirilin’s proposed alternate metric definition are described and we explain why ...

On The Parameterization Dependence Of The Energy Momentum Tensor And The Metric, N. E. J. BjerrumBohr, John Donoghue, Barry R. Holstein
John Donoghue
We use results by Kirilin to show that in general relativity the nonleading terms in the energymomentum tensor of a particle depends on the parameterization of the gravitational field. While the classical metric that is calculated from this source, used to define the leading longdistance corrections to the metric, also has a parameteriztion dependence, it can be removed by a coordinate change. Thus the classical observables are parameterization independent. The quantum effects that emerge within the same calculation of the metric also depend on the parameterization and a full quantum calculation requires the inclusion of further diagrams. However, within a ...

We use both meanfield methods and numerical simulation to study the phase diagram of classical particles interacting with a hard core and repulsive, soft shoulder. Despite the purely repulsive and isotropic interaction, this system displays a remarkable array of aggregate phases arising from the competition between the hardcore and softshoulder length scales, including fluid and crystalline phases with micellar, lamellar, and inverse micellar morphology. In the limit of large shoulder width to core size, we argue that this phase diagram has a number of universal features, and classify the set of repulsive shoulders that lead to aggregation at high density ...

Simulation And Analysis Of Ultrafast Laser Pulse Induced Plasma Generation In Dielectric Materials, Jeremy Gulley, Sebastian Winkler, William Dennis
Simulation And Analysis Of Ultrafast Laser Pulse Induced Plasma Generation In Dielectric Materials, Jeremy Gulley, Sebastian Winkler, William Dennis
Jeremy R. Gulley
Recent experiments on optical damage by ultrashort laser pulses have demonstrated that the temporal pulseshape can dramatically influence plasma generation in fused silica and sapphire. In this work a modified 3+1D nonlinear Schroedinger equation for the pulse propagation coupled to a rate equation for the plasma density in the dielectric material is used to simulate pulse propagation and plasma formation in a range of dielectric materials. We use these simulations to analyze the influence of pulsewidth, pulseshape and beam geometry on the formation of the electron plasma and hence damage in the bulk material. In particular, when possible, we ...

Jennifer Ross
Kinesin5 is an essential mitotic motor. However, how its spatialtemporal distribution is regulated in mitosis remains poorly understood. We expressed localization and affinity purificationtagged Eg5 from a mouse bacterial artificial chromosome (this construct was called mEg5) and found its distribution to be tightly regulated throughout mitosis. Fluorescence recovery after photobleaching analysis showed rapid Eg5 turnover throughout mitosis, which cannot be accounted for by microtubule turnover. Total internal reflection fluorescence microscopy and highresolution, singleparticle tracking revealed that mEg5 punctae on both astral and midzone microtubules rapidly bind and unbind. mEg5 punctae on midzone microtubules moved transiently both toward and away from ...

The writers describe their experience of a flight aboard NASA's C9 socalled Weightless Wonder aircraft. To celebrate the 2005 World Year of Physics, NASA, the American Association of Physics Teachers, and the American Physical Society cosponsored a contest to select teams of high school students and their mentors to fly an experiment aboard the aircraft, which simulates microgravity by conducting a series of parabolic maneuvers. In January 2005, the writers learned that their experiment, which studied how thin strands of liquid suspended between movable supports would respond to entering and exiting microgravity, had been selected as one of 6 ...

Twistgrainboundary phases in smectics are the geometrical analogs of the Abrikosov flux lattice in superconductors. At large twist angles, the nonlinear elasticity is important in evaluating their energetics. We analytically construct the height function of a π∕2 twistgrainboundary phase in smecticA liquid crystals, known as Schnerk’s first surface. This construction, utilizing elliptic functions, allows us to compute the energy of the structure analytically. By identifying a set of heretofore unknown defects along the pitch axis of the structure, we study the necessary topological structure of grain boundaries at other angles, concluding that there exist a set of privileged ...

Application Of The Msb PollutionFlushing Model To Great Salt Pond On Block Island, Stephen Mecca, Robert Barber, G. Mellor, G. Walsh
Stephen J. Mecca
The MSB singleembayment model of pollution flushing from a tidal basin has been applied to Great Salt Pond on Block Island and the results compared to an unpublished Rhodamine dye study conducted in 1986. The MSB model is based on the analytical tidal prism formulation developed by Barber. Both approaches have previously been validated against physical hydraulic modelling tests conducted on an idealised constantdepth rectangular basin, and the MSB model has been found to give excellent agreement against the laboratory data. However, until this present work, the MSB model has not been applied to a real embayment. The present paper ...

SelfHeating In Compost Piles Due To Biological Effects, Tim Marchant
SelfHeating In Compost Piles Due To Biological Effects, Tim Marchant
Tim Marchant
The increase in temperature in compost piles/landfill sites due to microorganisms undergoing exothermic reactions is modelled. A simplified model is considered in which only biological selfheating is present. The heat release rate due to biological activity is modelled by a function which is a monotonic increasing function of temperature over the range 0⩽T⩽a, whilst for T⩾a it is a monotone decreasing function of temperature. This functional dependence represents the fact that microorganisms die or become dormant at high temperatures. The bifurcation behaviour is investigated for 1d slab and 2d rectangular slab geometries. In both cases there ...
Solitary Wave Interaction For A HigherOrder Nonlinear Schrodinger Equation, Tim Marchant
Solitary Wave Interaction For A HigherOrder Nonlinear Schrodinger Equation, Tim Marchant
Tim Marchant
Solitary wave interaction for a higherorder version of the nonlinear Schrödinger (NLS) equation is examined. An asymptotic transformation is used to transform a higherorder NLS equation to a higherorder member of the NLS integrable hierarchy, if an algebraic relationship between the higherorder coefficients is satisfied. The transformation is used to derive the higherorder one and twosoliton solutions; in general, the Nsoliton solution can be derived. It is shown that the higherorder collision is asymptotically elastic and analytical expressions are found for the higherorder phase and coordinate shifts. Numerical simulations of the interaction of two higherorder solitary waves are also performed ...
