Dynamic compartmentalization of bacteria: accurate division in E. coli
Martin Howard, Andrew D. Rutenberg, Simon de Vet
Positioning of the midcell division plane within the bacterium E. coli is controlled by the min system of proteins: MinC, MinD and MinE. These proteins coherently oscillate from en…
Single-spin azimuthal asymmetry in exclusive electroproduction of pi^+ mesons
HERMES Collaboration, A. Airapetian
A single-spin asymmetry in the distribution of exclusively produced pi^+ mesons azimuthally around the virtual photon direction relative to the lepton scattering plane has been mea…
Ferroelectric Ordering in the Relaxor Pb(Mg1/3Nb2/3)O3 as Evidenced by Low-Temperature Phonon Anomalies
S. Wakimoto, C. Stock, R. J. Birgeneau +5
Neutron scattering measurements of the lowest-energy TO phonons in the relaxor Pb(Mg1/3Nb2/3)O3 (PMN) are reported for 10<=T<=750 K. The soft mode, which is overdamped by the polar…
Evidence for Static Magnetism in the Vortex Cores of Ortho-II YBaCuO
R. I. Miller, R. F. Kiefl, J. H. Brewer +8
Evidence for static alternating magnetic fields in the vortex cores of underdoped YBaCuO is reported. Muon spin rotation measurements of the internal magnetic field…
Perturbative expansions from Monte Carlo simulations at weak coupling: Wilson loops and the static-quark self-energy
H. D. Trottier, N. H. Shakespeare, G. P. Lepage +1
Perturbative coefficients for Wilson loops and the static-quark self-energy are extracted from Monte Carlo simulations at weak coupling. The lattice volumes and couplings are chose…
Non-Linear Sigma Model on Conifolds
R. Parthasarathy, K. S. Viswanathan
Explicit solutions to the conifold equations with complex dimension in terms of {\it{complex coordinates (fields)}} are employed to construct the Ricci-flat Kähler metrics…
