We consider studies of the atomic and magnetic structure near surfaces by photoelectron
diffraction and by the holographic inversion of both photoelectron diffraction data and …

The pioneeringwork of Markowitz (1952) formally established the intrinsic tradeoff between
risk and return. This paradigm provided the foundation upon which the modern theory of …

… The main contribution of this article is to codify and extend the earlier work of Menchero

… where the subscript j is a dummy index of summation. With the a1 thus determined, the …

… In this case, reversing the magnetization will not change the intensities of the states, but
will merely interchange the energetic positions of j,mj and j,mj . Such a situation is shown …

This article presents a set of qualitative characteristics and quantitative properties for arithmetic
multiperiod performance attribution. Such characteristics and properties are essential for …

Sample covariance matrices tend to underestimate the risk of optimized portfolios. In this
article, we identify special portfolios, termed “eigenportfolios,” that capture these systematic …

Background Laparoscopic ventral or incisional hernia repair requires intraperitoneal mesh
placement. This is associated with an increase in adhesions, bowel obstruction and …

… is the fact that the primary waves from the jmj both suffer the same overall phase shift …
unchanged, but the energetic positions of the jmj core states are simply interchanged due to the …
