Technology (1954) under the constant encouragement of Professor George J. Yevick (1954). The part concerning cosmology was largely developed at the National Research Council of Canada, Ottawa (1956). The author would like to express his appreciation to Professor Philip M. Morse of the Massachusetts Institute of Technology, to Dr. G. Herzberg and Dr. T.-Y. Wu of the National Research Council of ...

This paper presents a new criteria for matrix root-clustering in sophisticated, multiply-connected and non-convex regions of the complex plane. A concept of the closed forbidden region is defined as a complement of the root-clustering region to C and the concepts of the forbidden subregions and the expanded root-clustering regions are introduced to formulate the main results of the paper. The s...

In man, the relative concentrations of a-amino nitrogen in tungstic acid filtrates of erythrocytes and plasma have been determined by Hamilton and Van Slyke, using the ninhydrin method (2). Dunn et al. (3) reported assays of free tryptophan in blood serum, plasma, and red blood cells by microbiological means with Lactobacillus arabinosus. More recently, Gutman and Alexander (4) determined the l...

We used a random-assignment experiment in Los Angeles Unified School District to evaluate various non-experimental methods for estimating teacher effects on student test scores. Having estimated teacher effects during a pre-experimental period, we used these estimates to predict student achievement following random assignment of teachers to classrooms. While all of the teacher effect estimates ...

In 1970s, Gutman introduced the concept of the energy E (G) for a simple graph G, which is defined as the sum of the absolute values of the eigenvalues of G. This graph invariant has attracted much attention, and many lower and upper bounds have been established for some classes of graphs among which bipartite graphs are of particular interest. But there are only a few graphs attaining the equa...

Abstract We prove a general form of the regularity theorem for uniformity norms, and deduce an inverse these norms which holds class compact nilspaces including all abelian groups, also nilmanifolds; in particular we thus obtain first non-abelian versions such theorems. derive results from structure cubic couplings, thereby unifying with Host–Kra Ergodic Structure Theorem. A unification this ki...

Motivated by real-world machine learning applications, we consider a statistical classification task in sequential setting where test samples arrive sequentially. In addition, the generating distributions are unknown and only set of empirically sampled sequences available to decision maker. The maker is tasked classify sequence which known be generated according either one distributions. partic...
