Semilocal Fractional Instantons [PDF]

open access: yes, 2016
We find semi-local fractional instantons of codimension four in Abelian and non-Abelian gauge theories coupled with scalar fields and the corresponding ${\mathbb C}P^{N-1}$ and Grassmann sigma models at strong gauge coupling.

Non-symplectic symmetries and bi-Hamiltonian structures of the rational Harmonic Oscillator [PDF]

open access: yes, 2002
The existence of bi-Hamiltonian structures for the rational Harmonic Oscillator (non-central harmonic oscillator with rational ratio of frequencies) is analyzed by making use of the geometric theory of symmetries.

Genetic factors and diet affect long-bone length in the F34 LG,SM advanced intercross [PDF]

open access: yesMammalian Genome, 2010
Previous studies on the LG,SM advanced intercross line have identified approximately 40 quantitative trait loci (QTL) for long -bone (humerus, ulna, femur, and tibia) lengths. In this study, long-bone-length QTL were fine-mapped in the F(34) generation (n = 1424) of the LG,SM advanced intercross.

Sovereign debt and growth in Zambia: determining the tipping point

open access: yesSocial Sciences and Humanities Open, 2021
From the mid-1980s to mid-2000s, Zambia was in egregious debt distress, which resulted in debt relief under the HIPC initiative and MDRI in 2005. Surprisingly, Zambia's debt-to-GDP ratio has increased astronomically from about 22 percent in 2011 to 56 ...

More on the Isomorphism $SU(2)\otimes SU(2)\cong SO(4)$

open access: yes, 2006
In this paper we revisit the isomorphism $SU(2)\otimes SU(2)\cong SO(4)$ to apply to some subjects in Quantum Computation and Mathematical Physics. The unitary matrix $Q$ by Makhlin giving the isomorphism as an adjoint action is studied and generalized

Dirac-K\"ahler particle in Riemann spherical space: boson interpretation [PDF]

open access: yes, 2014
In the context of the composite boson interpretation, we construct the exact general solution of the Dirac--K\"ahler equation for the case of the spherical Riemann space of constant positive curvature, for which due to the geometry itself one may expect ...

Spontaneous Calcification in F34/Slc and F344/JCL Rats

open access: yesExperimental Animals, 1986
F344/Slc and F344/JCL rats 2 years of age were histologically examined for the incidence and distribution of calcification. In the male rats of both strains, calcification was observed in the testis, lung, brain, kidney, heart, aorta, cornea, prostate and seminal vesicle respectively.

Scattering matrices and expansion coefficients of Martian analogue palagonite particles

open access: yes, 2008
We present measurements of ratios of elements of the scattering matrix of Martian analogue palagonite particles for scattering angles ranging from 3 to 174 degrees and a wavelength of 632.8 nm.
