In the last issue, I presented a piece that called into question some of the techniques reported in two papers in high-profile journals that purported to provide statistical evidence for the linguistic status of some ancient symbol systems (Sproat 2010a). Not surprisingly the authors of those two papers took issue with a number of my claims, and have requested the opportunity to respond. The tw...

Thomson [4], et al. v. Thompson, et al. was a lawsuit filed in the United States District Court for the District of Columbia on 8 May 2001 as Civil Action Number 01-CV-0973. This lawsuit was filed in hopes of gaining injunctive relief against a moratorium on the federal funding of stem cell research. The plaintiffs in the case were seven prominent scientists who performed embryonic stem cell re...

In this article, we consider the uniqueness of the difference monomials $f^{n}(z)f(z+c)$. Suppose that $f(z)$ and $g(z)$ are transcendental meromorphic functions with finite order and $E_k(1, f^{n}(z)f(z+c))=E_k(1, g^{n}(z)g(z+c))$. Then we prove that if one of the following holds (i) $n geq 14$ and $kgeq 3$, (ii) $n geq 16$ and $k=2$, (iii) $n geq 22$ and $k=1$, then $f(z)equiv t_1g(z)$ or $f(...

In this paper, we examine the uniqueness (discrimination power) of a newly proposed graph invariant based on the matrix DMAX defined by Randić et al. In order to do so, we use exhaustively generated graphs instead of special graph classes such as trees only. Using these graph classes allow us to generalize the findings towards complex networks as they usually do not possess any structural const...

Solving discrete ill-posed problems via Tikhonov regularization introduces the problem of determining a regularization parameter. There are several methods available for choosing such a parameter, yet, in general, the uniqueness of this choice is an open question. Two empirical methods for determining a regularization parameter (which appear in the biomedical engineering literature) are the com...

Error-contaminated systems Ax ≈ b, for which A is ill-conditioned, are considered. Such systems may be solved using Tikhonov-like regularized total least squares (R-TLS) methods. Golub et al, 1999, presented a direct algorithm for the solution of the Lagrange multiplier formulation for the R-TLS problem. Here we present a parameter independent algorithm for the approximate R-TLS solution. The a...

1. The accurate and reliable assessment of statistical disclosure risk is a necessary pre-cursor of the efficient application of disclosure control techniques. Research on statistical disclosure risk assessment with respect to microdata files has two major themes. The first uses the concept of uniqueness, examining the level of unique individuals or households within populations and samples (Se...

Methods: This study relies solely on simulations of a transmit-array head coil at 7T. The coil consisted of 8 stripline dipoles distributed every 40degrees on a cylindrical surface of 27.6-cm diameter, leaving an open space in front of the patient’s eyes. An eight-anatomical structure human head model (provided by Aarkid, East Lothian, Scotland) was placed at the centre of the coil. The same he...
