Model for Anisotropic Directed Percolation
We propose a simulation model to study the properties of directed percolation
in two-dimensional (2D) anisotropic random media. The degree of anisotropy in
the model is given by the ratio between the axes of a semi-ellipse
enclosing the bonds that promote percolation in one direction. At percolation,
this simple model shows that the average number of bonds per site in 2D is an
invariant equal to 2.8 independently of . This result suggests that
Sinai's theorem proposed originally for isotropic percolation is also valid for
anisotropic directed percolation problems. The new invariant also yields a
constant fractal dimension for all , which is the same
value found in isotropic directed percolation (i.e., ).Comment: RevTeX, 9 pages, 3 figures. To appear in Phys.Rev.
Finite-Size Scaling in Two-dimensional Continuum Percolation Models
We test the universal finite-size scaling of the cluster mass order parameter
in two-dimensional (2D) isotropic and directed continuum percolation models
below the percolation threshold by computer simulations. We found that the
simulation data in the 2D continuum models obey the same scaling expression of
mass M to sample size L as generally accepted for isotropic lattice problems,
but with a positive sign of the slope in the ln-ln plot of M versus L. Another
interesting aspect of the finite-size 2D models is also suggested by plotting
the normalized mass in 2D continuum and lattice bond percolation models, versus
an effective percolation parameter, independently of the system structure (i.e.
lattice or continuum) and of the possible directions allowed for percolation
(i.e. isotropic or directed) in regions close to the percolation thresholds.
Our study is the first attempt to map the scaling behaviour of the mass for
both lattice and continuum model systems into one curve.Comment: 9 pages, Revtex, 2 PostScript figure

Ī±āE-catenin binds to dynamitin and regulates dynactin-mediated intracellular traffic
Ī±āEpithelial catenin (E-catenin) is an important cellācell adhesion protein. In this study, we show that Ī±āE-catenin also regulates intracellular traffic by binding to the dynactin complex component dynamitin. Dynactin-mediated organelle trafficking is increased in Ī±āE-cateninā/ā keratinocytes, an effect that is reversed by expression of exogenous Ī±āE-catenin. Disruption of adherens junctions in low-calcium media does not affect dynactin-mediated traffic, indicating that Ī±āE-catenin regulates traffic independently from its function in cellācell adhesion. Although neither the integrity of dynactinādynein complexes nor their association with vesicles is affected by Ī±āE-catenin, Ī±āE-catenin is necessary for the attenuation of microtubule-dependent trafficking by the actin cytoskeleton. Because the actin-binding domain of Ī±āE-catenin is necessary for this regulation, we hypothesize that Ī±āE-catenin functions as a dynamic link between the dynactin complex and actin and, thus, integrates the microtubule and actin cytoskeleton during intracellular trafficking

Short Terahertz Pulses from Semiconductor Surfaces: The Importance of Bulk DifferenceāFrequency Mixing
The crystallographic orientation dependence of the farāinfrared (FIR) light generated at the (001) surface of a zincblende semiconductor is shown to derive principally from bulk differenceāfrequency mixing. A strong modulation is observed for 1āGW/cm2 pulses on InP, which demonstrates that the radiated FIR wave produced by bulk optical rectification is comparable to that generated by the transport of photoinjected carriers. Using the bulk rectification light as a clock, we show that more than 95% of the light produced from an InP (111) crystal by 100āfs, 100āĪ¼J pulses is generated in a time shorter than the excitation pulse

Performing Kongwuās (ē©ŗē”, Emptiness, Nothingness) Attitude Towards Language, Time, and Self: Responding to Nam June Paik, John Cage, and Marina AbramoviÄ
---Since 1950s, the concept of Kongwu (ē©ŗē”, Emptiness, Nothingness) has migrated into American-European experimental performances, including those of John Cage and Cage-influenced artists who developed Happenings, Fluxus, and intermedia practices. This research-through-practice investigates how the concept of kongwu, an intercultural synthesis of Chinese Daoism and Indian Buddhism, may shape the principles underlying performance making and how performance may, in turn, elucidate Kongwu way of making sense the world.
---The installation-performance, Poem without Language contemplates Kongwuās distrust of language by undermining the communicative purpose of writing and responds to Nam June Paikās approach to media language. The research practice, One Street, Three Persons, Different Narratives, and Different Memories responds to John Cageās use of silence to revise time and measurement, and exposes the habit, how we experience the āpresentā as accumulations of the past, and how we order experiences as a linear continuity, which we call ātimeā. My performance, ā¦ is Present suggests different definitions of the āmeditative mindā and ābeing-here-and-nowā and critiques the relationship between embodiment and identity in Marina AbramoviÄās construction of āsuchnessā.
----Three works offer one response to the poetics and politics of intercultural encounters in the context of Chan/Zen in intermedia performance. My research-through-practice sheds light on Kongwu way of experiencing, particularly Kongwuās attitude towards language, time, and self.University of Exete
Penetration of hot electrons through a cold disordered wire
We study a penetration of an electron with high energy E<<T through strongly
disordered wire of length L<<a (a being the localization length). Such an
electron can loose, but not gain the energy, when hopping from one localized
state to another. We have found a distribution function for the transmission
coefficient t. The typical t remains exponentially small in L/a, but with the
decrement, reduced compared to the case of direct elastic tunnelling. The
distribution function has a relatively strong tail in the domain of anomalously
high t; the average ~(a/L)^2 is controlled by rare configurations of
disorder, corresponding to this tail.Comment: 4 pages, 5 figure
