Deconfinement transition and monopoles in QCD
The role of monopoles in the deconfinement transition is discussed in the
framework of abelian projection in the maximally abelian gauge in
QCD. Only one (or a few near ) long connected monopole loop
exists uniformly through the whole lattice in each vacuum configuration in
addition to some very short loops in the confinement phase and the long loop
disappears in the deep deconfinement region. Energy-entropy balance of the long
loops of maximally extended monopoles explains the existence of the
deconfinement transition and reproduces roughly the value of the critical
temperature.Comment: 23 pages (14 figures) ,late
Inter-meson Potentials in Dual Ginzburg-Landau Theory
We calculate inter-meson potentials numerically by solving classical
equations of motion derived from Dual Ginzburg-Landau (DGL) Theory. Inter-meson
potentials in DGL theory are shown to be similar to those of the string-flip
model and well reproduce behaviors of the short-range interaction at the
classical level. We also compare our results with those from lattice QCD Monte
carlo calculations.Comment: 18 pages, latex, 8 figure
Monopoles and deconfinement transition in finite temperature QCD
We investigate the role of monopoles in the deconfinement transition of
finite temperature QCD in the maximally abelian gauge. In the
confinement phase a long monopole loop exists in each configuration, whereas no
long loop exists in the deep deconfinement region. Balancing of the energy and
the entropy of loops of the maximally extended monopoles can explain the
occurrence of the deconfinement transition.Comment: 3 pages (4 figures). Contribution to Lattice '9
Study of gauge (in)dependence of monopole dynamics
We investigated the gauge (in)dependence of the confinement mechanism due to
monopole condensation in SU(2) lattice QCD by various abelian projections. We
found (1) the string tension can be reproduced by monopoles alone also in
Polyakov gauge and (2) the behaviors of the Polyakov loop at the critical
temperature seem to be explained by the uniformity breaking of the monopole
currents in every gauge.Comment: 4pages (7 figures), Latex, Contribution to Lattice 9
String tension and monopoles in SU(2) QCD
Monopole and photon contributions to abelian Wilson loops are calculated
using Monte-Carlo simulations of finite-temperature QCD in the
maximally abelian gauge. Long monopole loops alone are responsible for the
behavior of the string tension in the confinement phase up to the critical
. Short monopole loops and photons do not contribute to the string
tension. The abelian and the monopole spacial string tensions (both of which
agree with the normal ones for ) show a scaling
behavior in the deconfinement phase. The abelian spacial string tension is in
agreement with the full one even in the deconfinement phase.Comment: 10 Pages + 1 table + 8 figures, KANAZAWA 94-1
Three topics of monopole dynamics in abelian projected QCD
Three topics about monopole dynamics after abelian projection are reported.
The first is the new and detailed analyses of monopole action obtained
after the block-spin transformation on the dual lattice. The
dependence for all couplings are well fitted with a universal curve. The
distance dependence of the couplings is well reproduced by a massive propagator
with the mass in unit of . The second is the monopole action
recently obtained. The third is new interesting gauges showing abelian and
monopole dominances as in the maximally abelian gauge.Comment: Talk presented at LATTICE96(topology), 4 Pages, 7 eps figure
Human NINEIN polymorphism at codon 1111 is associated with the risk of colorectal cancer
NINEIN serves an essential role in centrosome function as a microtubule organizing center, and in the reformation of the interphase centrosome architecture following mitosis. In the present study, the association between NINEIN Pro1111Ala (rs2236316), a missense single nucleotide polymorphism, and the risk of colorectal cancer (CRC), related to smoking and alcohol consumption habits in 200 patients with CRC and 1,141 cancer‑free control participants were assessed in a case‑control study performed in Japan. The results showed that the NINEIN Ala/Ala genotype compared with the Pro/Pro genotype was significantly more associated with an increased risk of CRC, and the males with the Ala/Ala genotype exhibited a significantly increased risk of CRC compared with those with Pro/Pro and Pro/Ala genotypes. Stratified analyses of the Ala/Ala genotype with CRC risk further showed an increased association in never/light drinkers (<23 g of ethanol/day), in male never/light drinkers and in male patients with rectal cancer. These findings suggest that the genetic variant of the NINEIN Pro1111Ala polymorphism has a significant effect on CRC susceptibility in the Japanese population
