Emptiness Formation Probability and Quantum Knizhnik-Zamolodchikov Equation [PDF]
, 2002 We consider the one-dimensional XXX spin 1/2 Heisenberg antiferromagnet at zero temperature and zero magnetic field. We are interested in a probability of formation of a ferromagnetic string in the antiferromagnetic ground-state.

Affine Jordan cells, logarithmic correlators, and hamiltonian reduction
, 2006 We study a particular type of logarithmic extension of SL(2,R) Wess-Zumino-Witten models. It is based on the introduction of affine Jordan cells constructed as multiplets of quasi-primary fields organized in indecomposable representations of the Lie ...

Naturally light invisible axion and local Z13⊗Z3 symmetries [PDF]
Physical Review D, 2004 We show that by imposing local $Z_{13}\otimes Z_3$ symmetries in an $SU(2)\otimes U(1)$ electroweak model we can implement an invisible axion in such a way that (i) the Peccei-Quinn symmetry is an automatic symmetry of the classical Lagrangian; and (ii) the axion is protected from semi classical gravitational effects.

Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

Family And Economic Growth In Poland
Folia Oeconomica Stetinensia, 2014 In the article we test the hypothesis that the weakening of family ties, as measured by the reduction in the number of marriages, a cascade of divorces and the decrease in the fertility rate, has brought about an economic slowdown in Poland.

An SU(5)$\otimes$Z_{13} Grand Unification Model
, 2007 We propose an SU(5) grand unified model with an invisible axion and the unification of the three coupling constants which is in agreement with the values, at $M_Z$, of $\alpha$, $\alpha_s$, and $\sin^2\theta_W$.

Veterinary Dermatology, EarlyView.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

Hierarchical Mass Matrices in a Minimal SO(10) Grand Unification I
, 1994 We consider a minimal SO(10) unified model with horizontal Peccei-Quinn symmetry. The hierarchical structure of quark-lepton mass matrices is naturally implemented by the remnants of certain irrelevant terms.

RELICS: Strong Lens Models for Five Galaxy Clusters From the Reionization Lensing Cluster Survey [PDF]
, 2018 Strong gravitational lensing by galaxy clusters magnifies background galaxies, enhancing our ability to discover statistically significant samples of galaxies at z>6, in order to constrain the high-redshift galaxy luminosity functions.
