Quantum states of elementary three-geometry [PDF]

, 2001
We introduce a quantum volume operator $K$ in three--dimensional Quantum Gravity by taking into account a symmetrical coupling scheme of three SU(2) angular momenta.

Effect of Aerobic Exercise on Left Ventricular Connexin43 Expression and Distribution in Juvenile and Young Adult Rats

Journal of Biomedicine and Translational Research, 2021
Background: Gap Junction (GJ) plays a role in supporting the heart electricity. Connexin43 (Cx43) as the main protein constituent of GJ in left cardiac ventricle, will increase in number and slightly redistributed to the lateral sides of cardiomyocytes ...

Simplifying the spectral analysis of the volume operator [PDF]

, 1997
The volume operator plays a central role in both the kinematics and dynamics of canonical approaches to quantum gravity which are based on algebras of generalized Wilson loops.

Josephson effect in two-band superconductors [PDF]

, 2019
We study theoretically the Josephson effect between two time-reversal two-band superconductors, where we assume the equal-time spin-singlet $s$-wave pair potential in each conduction band.

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.

Quasi-local Update Algorithms for Numerical Simulations of d=3 SU(2) LGT in the Dual Formulation [PDF]

, 2000
In the dual formulation of d=3 SU(2) LGT, the link variables are group representations and valid configurations are those satisfying a number of triangle inequalities.

Lost and Wasted Human Capital – How Transformations of Family, Socialization, and Population Control Influence Welfare and Well-Being

Folia Oeconomica Stetinensia, 2018
This paper analyzes the influence of the transformations of marriage and family on the human capital (HC) creation in contemporary Western societies. One of the basic assumptions included here is that these processes are connected with profound socio ...

Uniform Semiclassical Approximation for the Wigner $6j$ Symbol in Terms of Rotation Matrices [PDF]

, 2009
A new uniform asymptotic approximation for the Wigner $6j$ symbol is given in terms of Wigner rotation matrices ($d$-matrices). The approximation is uniform in the sense that it applies for all values of the quantum numbers, even those near caustics. The
