Comment about UV regularization of basic commutators in string theories

Recently proposed by Hwang, Marnelius and Saltsidis zeta regularization of basic commutators in string theories is generalized to the string models with non-trivial vacuums. It is shown that implementation of this regularization implies the cancellation of dangerous terms in the commutators between Virasoro generators, which break Jacobi identity.Comment: LaTeX, 9 pages, no figures, submitted to Physics Letters

Ratios of BB and DD Meson Decay Constants in Improved Mock Meson Model

We calculate the ratio $f_{B_s}/f_{B_d}$ by following the Oakes' method which is based on chiral symmetry breaking, but we improve his calculation by performing the calculation of the factor $$/$$ in the mock meson model. In this calculation we improved the mock meson model by using the value of the parameter $\beta$ which is obtained by the variational method in the relativistic quark model. We also calculate $f_{D_s}/f_{D_d}$, and then $(f_{B_s}/f_{B_d})\, /\, (f_{D_s}/f_{D_d})$. In this method we also obtain the ratio $f_{B_s}/f_{D_s}$ and $f_{B_d}/f_{D_d}$ which are important for the knowledge of CP violation and $B$-$\bar{B}$ mixing.Comment: 9 pages, 1 Postscript figur

The Western New York Entrepreneurship Ecosystem: Rapid Discovery Assessment and Recommendations for the Future

In an effort to learn more about the current state of Western New York's entrepreneurial ecosystem and to inform future strategy, the Ralph C. Wilson, Jr. Foundation engaged Victor & Company, led by Victor W. Hwang, to conduct a three-month rapid discovery process.This report was written and published by Victor & Company, led by Victor W. Hwang, with support from the Ralph C. Wilson, Jr. Foundation

Evidence for a Quantum Hall Insulator in an InGaAs/InP Heterostructure

We study the quantum critical behavior of the plateau-insulator (PI) transition in a low mobility InGaAs/InP heterostructure. By reversing the direction of the magnetic field (B) we find an averaged Hall resistance \rho_xy which remains quantized at the plateau value h/e^2 throughout the PI transition. We extract a critical exponent \kappa'= 0.57 +/- 0.02 for the PI transition which is slightly different from (and possibly more accurate than) the established value 0.42 +/- 0.04 as previously obtained from the plateau-plateau (PP) transitions.Comment: 3pages, 2 figures; submitted to EP2DS-14 conference proceeding
