Continuum of many-particle states near the metal-insulator transition in the Hubbard model

The strong coupling diagram technique is used for investigating states near the metal-insulator transition in the half-filled two-dimensional repulsive Hubbard model. The nonlocal third-order term is included in the irreducible part along with local terms of lower orders. Derived equations for the electron Green's function are solved by iteration for moderate Hubbard repulsions and temperatures. Starting iteration from Green's functions of the Hubbard-I approximation with various distances of poles from the real frequency axis continua of different metallic and insulating solutions are obtained. The insulating solutions vary in the width of the Mott gap, while the metallic solutions differ in the shape of the spectral function in the vicinity of the Fermi level. Besides, different scenarios of the metal-insulator transition -- with a sudden onset of a band of mobile states near the Fermi level and with gradual closure of the Mott gap -- are observed with a change in temperature. In spite of these dissimilarities, all solutions have a common curve separating metallic and insulating states in the phase diagram. Near this curve metallic and insulating solutions coexist. For moderate Hubbard repulsions metallic solutions are not Fermi liquids.Comment: 10 pages, 9 figure

Three Strategies for Managing through Economic Change

[Excerpt] Since its implementation, strategic human resource management has helped assuage the age-old conflict formerly accepted to be inherent between employees and management. The interests of these two parties have long been erroneously assumed to be diametrically opposed. Nevertheless, the development of effective strategic HR policies has demonstrated that gains for both businesses and workers can be made by pursuing more collaborative relations between the two. Specifically, the utilization of effective talent management and career development strategies has gone a long way toward producing a more amicable relationship between employees and management, and by extension more productive and profitable firms

Review of Chagas Disease and Treatment Obstacles to Eradication

The World Health Organization and the Center for Disease Control reports Chagas disease, or American trypanosomiasis, as a major neglected tropical disease prevalent in 21 endemic Latin American countries. The agent of the disease is a single-celled protozoan parasite, Trypanosoma cruzi, and common modes of transmission include infected feces of a triatomine bug, crossing the placental barrier, and blood products. The two phases of infection are acute and chronic, and the three most affected body systems are cardiovascular, digestive, and nervous. Although research has led to several advances in the knowledge of CD, there are gaps in treatment and epidemiological research, leaving millions of people susceptible to infection
