The study of knowledge has always been one of the central issues of the AI research. The general belief has been that "the more you have it the better you are." It was well understood that incorrect knowledge is harmful and should be avoided, but correct knowledge had been mostly considered beneficial. The potential harmfulness of correct knowledge received attention in very few early works but...

We prove that for every integer g ≥ 0 and graph H, there exists a polynomial-time algorithm deciding whether an input graph of Euler genus at most g can be contracted to H. We introduce surface contractions and surface topological minors of embedded graphs. We prove that an embedded graph H is a surface contraction of an embedded graph G if and only if the geometric dual of H is a surface topol...

This article describes a quantum mechanical reactive scattering program for atom–diatom chemical reactions that we have written during the past several years. The program uses a coupled-channel hyperspherical coordinate method to solve the Schrödinger equation for the motion of the three nuclei on a single Born–Oppenheimer potential energy surface. It has been tested for all possible deuterium-...

X-ray photoelectron and electron energy loss spectroscopic (XPS-EELS) studies reveal that the following species are present when a mixture of CO2 and water vapour is exposed to the clean Mg(100) surface at 110K: CO3(a), C(a) CH(a), OH(a). The reactive chemisorptions of CO2 and H2O vapour coadsorbed on a Mg surface ...

One of the efficient and powerful schemes to solve linear and nonlinear equations is homotopy analysis method (HAM). In this work, we obtain the approximate solution of a system of partial differential equations (PDEs) by means of HAM. For this purpose, we develop the concept of HAM for a system of PDEs as a matrix form. Then, we prove the convergence theorem and apply the proposed method to fi...

In order to create Fe2O3 and Fe2O3·H2O nanoparticles, various polymers were used as dispersing agents, and the resulting effects on the dispersibility and nanoparticulation of the iron oxides were evaluated. It was revealed that not only the solution viscosity but also the molecular length of the polymers and the surface tension of the particles affected the dispersibility of Fe2O3 and Fe2O3·H2...

instruction that teachers bring to their students; therefore, preparing new teachers well is crucial to student achievement (Chetty, Friedman, & Rockoff, 2014; Rivkin, Hanushek, & Kain, 2005; Rockoff, 2004). Recent research on graduates of teacher preparation programs suggests that some programs are producing new teachers who are more capable than others (Boyd, Grossman, Lankford, Loeb, & Wycko...
