… The returns R are strongly correlated with the volatility V and, as in Kakushadze and …
Consistent with Kakushadze and Tulchinsky (2016), we have no statistically significant dependence …

We consider string perturbative expansion in the presence of D-branes imbedded in
orbifolded space-time. In the regime where the string coupling is weak and α′ → 0, the string …

… Let us mention that (46) generally is farther away than (16) (assuming are based on a
weighted regression with z i =1/σ i 2 ) from the optimized solution we discuss in the next section. …

… at energies below/z) can be integrated out. For simplicity, in the following we will set/z = 1.
The quantum constraint follows from the F-flatness condition for the field A and reads …

We consider four-dimensional N= 1 supersymmetric gauge theories obtained via orientifolds
of type IIB on Abelian C 3/Γ orbifolds. We construct all such theories that have a well-…

We estimate treatment cost-savings from early cancer diagnosis. For breast, lung, prostate
and colorectal cancers and melanoma, which account for more than 50% of new incidences …

We review the construction and classification of three-family grand unified models within the
framework of asymmetric orbifolds in perturbative heterotic superstring. We give a detailed …

… So, following [9], [8], we set 31 (6) K = Round ( eRank ( Ψ ) ) Here eRank(Z) is the effective …
Z. It is defined as(7)(8)(9) eRank ( Z ) = exp ( H ) where λ (a) are the L positive eigenvalues of Z…

In this paper we discuss some aspects of N = 1 type I-heterotic string duality in four dimensions.
We consider a particular example of a (weak-weak) dual pair where on the type I side …

Extending the recent work by M. Bershadsky, Z. Kakushadze and C. Vafa (hep-th/9803076),
we consider string perturbative expansion in the presence of D-branes and orientifold …
