Humans are deeply social animals. Our beliefs, desires, and behaviors are affected by social preferences, our relationships, and the social contexts in which we live and make decisions. We are “group-minded individuals” who see the world from a social as well as an individual perspective; we understand what is in the minds of others and often act as if our brains are networked with the brains o...

Matlab, Python and R have all been used successfully in teaching college students fundamentals of mathematics & statistics. In today’s data driven environment, the study through big analytics is very powerful, especially for purpose decision making using statistically this rich environment. MatLab can be to teach introductory such as calculus Both make decisions involving data. On one hand,...

Based on the HVZ theorem and dilation analyticity of the pseudorelativistic no-pair Jansen-Hess operator, it is shown that for subcritical potential strength (Z ≤ 90) the singular continuous spectrum is absent. The bound is slightly higher (Z ≤ 102) for the Brown-Ravenhall operator whose eigenvalues λ are, by the virial theorem, confined to λ < 2m if Z ≤ 50.

Blockade of the CD40 and CD28 costimulatory pathways significantly prolongs allograft survival; however, certain strains of mice (i.e., C57BL/6) are relatively resistant to the effects of combined CD40/CD28 blockade. We have previously shown that the costimulation blockade-resistant phenotype can be attributed to a subset of CD8+ T cells and is independent of CD4+ T cell-mediated help. Here we ...

Nearly all of today’s Big Data systems are passive in nature. We demonstrate our Big Active Data (“BAD”) system, a scalable system that continuously and reliably captures Big Data and facilitates the timely and automatic delivery of new information to a large population of interested users as well as supporting analyses of historical information. We built our BAD project by extending an existin...

Small coherence (or, incoherence) has nice properties as we shall see now. Assume A has coherence μ < 1. Prove that for all s < 1/μ, A has RIP with parameters s, δ = sμ. Hint: For s-sparse x, write down ‖Ax‖ = (Ax)Ax using inner products of columns of A. Note: There exist deterministic constructions of k×d matrices with incoherence ∼ 1/ √ k, which by the above imply RIP with parameters s = √ k,...

In this paper we explain the apparent ”diversification discount” of conglomerates without assuming inefficient-cross subsidisation through internal capital markets. Instead we assume that an internal capital market efficiently redistributes scare resources across a conglomerate’s divisions between successive production periods. The need for redistribution arises from the fact that resources may...
