    We study the infinite U Hubbard model with one hole doped away half-filling, in triangular and square lattices with frustrated hoppings that invalidate Nagaoka's theorem, by means of the density matrix renormalization group. We find that these kinetically frustrated models have antiferromagnetic ground states with classical local magnetization in the thermodynamic limit. We identify the mechanism of this kinetic antiferromagnetism with the release of the kinetic energy frustration as the hole moves in the established antiferromagnetic background. This release can occurs in two different ways: by a non-trivial spin-Berry phase acquired by the hole or by the effective vanishing of the hopping amplitude along the frustrating loops.Comment: 12 pages and 4 figures, with Supplementary Material.

    Economic Impact of Quinoa Consumption in the Diet of University Students Case: ESPOCH Agroindustry Career

    Get PDF
    Quinoa is an ancestral plant, originally cultivated in the Andes. It is a product with exceptional nutritional value and it has been important in the socio-economic evolution of the Andean population. Food is considered a natural, ecological and economic product. Since quinoa has the same amount of protein as meat, it can complement people鈥檚 daily food at a very low cost. The objective of this work was to carry out market research to determine the knowledge of university students about the protein value of quinoa in their diet and its purchasing power. The design was semi-experimental and descriptive. The study population was students of the Agroindustry degree of the Faculty of Livestock Sciences of the Higher Polytechnic School of Chimborazo. Data were collected through a questionnaire, which contained ten open and closed questions. 192 people were surveyed. Data were also collected through direct observations in the food laboratory. The results indicated a high level of ignorance of the benefits of quinoa. A lack of knowledge about quinoa can result in smaller economic benefits for those who produce this high protein food, which in most cases are indigenous communities. Keywords: economic, consumption, quinoa, incidence.

    Purpose: This study aims to examine the internal brand knowledge dissemination process in the banking sector and its effects on employees. Specifically, it focuses on the key roles of employee identification with both the organization and with the customer as antecedents of behaviors supportive of the brand, i.e. employee citizenship behaviors and recommendation behaviors. Design/methodology/approach: An empirical study was carried out in a major Spanish bank. Data gathered from a survey of 315 employees were analyzed through structural equation modeling. Findings: The results showed that employees'' perceptions of brand value congruence are key in explaining their identification with both the organization and with the customer. However, the employees'' perceptions of the brand''s authenticity explained only their recommendations of the bank as a good place to work. Originality/value: These findings contribute to the advance in the current knowledge of the role of variables such as brand authenticity and employee鈥揷ustomer identification in internal brand management. From a managerial viewpoint, the results provide insights into the importance of employees'' perceptions and attitudes when it comes to brand knowledge dissemination. 漏 2021, Emerald Publishing Limited

    IDO1 is an Integral Mediator of Inflammatory Neovascularization.

    The immune tolerogenic effects of IDO1 (indoleamine 2,3-dioxygenase 1) have been well documented and genetic studies in mice have clearly established the significance of IDO1 in tumor promotion. Dichotomously, the primary inducer of IDO1, the inflammatory cytokine IFN纬 (interferon-纬), is a key mediator of immune-based tumor suppression. One means by which IFN纬 can exert an anti-cancer effect is by decreasing tumor neovascularization. We speculated that IDO1 might contribute to cancer promotion by countering this anti-neovascular effect of IFN纬, possibly through IDO1-potentiated elevation of the pro-tumorigenic inflammatory cytokine IL6 (interleukin-6). In this study, we investigated how genetic loss of IDO1 affects neovascularization in mouse models of oxygen-induced retinopathy and lung metastasis. Neovascularization in both models was significantly reduced in mice lacking IDO1, was similarly reduced with loss of IL6, and was restored in both cases by concomitant loss of IFN纬. Likewise, the lack of IDO1 or IL6 resulted in reduced metastatic tumor burden and increased survival, which the concomitant loss of IFN纬 abrogated. This insight into IDO1\u27s involvement in pro-tumorigenic inflammatory neovascularization may have important ramifications for IDO1 inhibitor development, not only in cancer where clinical trials are currently ongoing, but in other disease indications associated with neovascularization as well

    The Convective Urca Process with Implicit Two-Dimensional Hydrodynamics

    Consideration of the role of the convective flux in the thermodymics of the convective Urca neutrino loss process in degenerate, convective, quasi-static, carbon-burning cores shows that the convective Urca process slows down the convective current around the Urca-shell, but, unlike the "thermal" Urca process, does not reduce the entropy or temperature for a given convective volume. Here we demonstrate these effects with two-dimensional numerical hydrodynamical calculations. These two-dimensional implicit hydrodynamics calculations invoke an artificial speeding up of the nuclear and weak rates. They should thus be regarded as indicative, but still qualitative. We find that, compared to a case with no Urca-active nuclei, the case with Urca effects leads to a higher entropy in the convective core because the energy released by nuclear burning is confined to a smaller volume by the effective boundary at the Urca shell. All else being equal, this will tend to accelerate the progression to dynamical runaway. We discuss the open issues regarding the impact of the convective Urca process on the evolution to the "smoldering phase" and then to dynamical runaway.Comment: 22 pages, 11 figures, accepted for publication in the Astrophysical Journa
