-Regular Basis for non-polylogarithmic multiloop integrals and total cross section of the process e + e − → 2( Q Q¯$$ \overline{Q} $$ )
Journal of High Energy Physics, 2019Co-Authors: Roman N. Lee, A. I. OnishchenkoAbstract:We argue that in many physical calculations where the “elliptic” sectors are involved, one can express the results via iterated integrals with almost all weights being rational. Our method is based on the existence of

$\epsilon$-Regular Basis for non-polylogarithmic multiloop integrals and total cross section of the process $e^+e^-\to 2(Q\bar Q)$
arXiv: High Energy Physics - Phenomenology, 2019Co-Authors: Roman N. Lee, A. I. OnishchenkoAbstract:We argue that in many physical calculations where the "eliptic" sectors are involved, one can express the results via iterated integrals with almost all weights being rational. Our method is based on the existence of $\epsilon$-Regular Basis, which is akin to the $\epsilon$-finite Basis defined in Ref. [hep-ph/0601165]. As a demonstration of our technique, we calculate the photon contribution to the total cross section of the production of two $Q\bar Q$ pairs in the electron-positron collisions.

Regular Basis and r matrices for the su n k knizhnik zamolodchikov equation
arXiv: High Energy Physics - Theory, 2000Co-Authors: Ludmil Hadjiivanov, Ya. S. Stanev, I. T. TodorovAbstract:Dynamical R-matrix relations are derived for the group-valued chiral vertex operators in the SU(n) WZNW model from the KZ equation for a general four-point function including two step operators. They fit the exchange relations of the U q (sl n ) covariant quantum matrix algebra derived previously by solving the dynamical Yang–Baxter equation. As a byproduct, we extend the Regular Basis introduced earlier for SU(2) chiral fields to SU(n) step operators and display the corresponding triangular matrix representation of the braid group.

Examination compliance and screening for diabetic retinopathy: A 2-year follow-up study
Clinical and Experimental Ophthalmology, 2000Co-Authors: S. J. Lee, C Sicari, C A Harper, H. R. Taylor, Paul M Livingston, Catherine A Mccarty, Jill E. KeeffeAbstract:Early detection and timely treatment of diabetic retinopathy can preserve vision, yet many people with diabetes do not have their eyes examined Regularly. The purpose of this study was to examine eye care practices of people with diabetes who had not previously accessed eye care services on a Regular Basis. Screening with non-mydriatic retinal photography for diabetic retinopathy was initiated in 1996, and targeted people with diabetes who did not access eye care services on a Regular Basis. Each test area was revisited 2 years after the initial screening. Patients that did not attend the biennial screening were followed up by mail survey. Although none of the participants in this study had been previously accessing eye care services on a Regular Basis, 87% did so after attending the screening. These results indicate that mobile screening with non-mydriatic photography, as an adjunct to current eye care services, has the potential to increase examination compliance for diabetic retinopathy and to achieve sustained behaviour change.
