Acerca de la escena artística de la Calle 10. Un clúster creativo pionero en la Ciudad de Nueva York

Since the beginning of the fifties, 10th Street concentrated an artistic activity unprecedented in the history of the paradigmatic City of New York. A significant number of artists and their diverse ways of production were hosted in the buildings of this urban artery. While the Greenwich Village bohemia or the Coenties Slip’s artists pioneered a sporadic and spontaneous relationship with the city, this synergistic model of multiple and connected art spaces along this axis could be identified as a first creative cluster, inspiring later important phenomena such as the colonization of the South of Houston Street at the hands of the artistic counterculture. The 10th Street artists’ activity would range from singular spaces and projects, such as the Tenth Street Studio Building, to the first structures of artistic cooperatives, Tenth Street Co-ops. While showing the groundbreaking relationship between this city and its art, this article particularly investigates the architectural and cultural scene of 10th Street, which would ultimately influence the 1960s’ popular urban model of the artistic district. Moreover, the revelation of its history is intended to build the antecedents of certain contemporary intervention practices and theories that rely on culture as a way of city improvement.Desde el comienzo de la década de los 50, la Calle 10 concentró desde el inicio una actividad artística sin precedentes en la historia de la paradigmática ciudad de Nueva York.

Hypoxic Cell Waves around Necrotic Cores in Glioblastoma: A Biomathematical Model and its Therapeutic Implications

Glioblastoma is a rapidly evolving high-grade astrocytoma that is distinguished pathologically from lower grade gliomas by the presence of necrosis and microvascular hiperplasia. Necrotic areas are typically surrounded by hypercellular regions known as "pseudopalisades" originated by local tumor vessel occlusions that induce collective cellular migration events. This leads to the formation of waves of tumor cells actively migrating away from central hypoxia. We present a mathematical model that incorporates the interplay among two tumor cell phenotypes, a necrotic core and the oxygen distribution. Our simulations reveal the formation of a traveling wave of tumor cells that reproduces the observed histologic patterns of pseudopalisades. Additional simulations of the model equations show that preventing the collapse of tumor microvessels leads to slower glioma invasion, a fact that might be exploited for therapeutic purposes.Comment: 29 pages, 9 figure

Application of the coherent state formalism to multiply excited states

A general expression is obtained for the matrix element of an m-body operator between coherent states constructed from multiple orthogonal coherent boson species. This allows the coherent state formalism to be applied to states possessing an arbitrarily large number of intrinsic excitation quanta. For illustration, the formalism is applied to the two-dimensional vibron model [U(3) model], to calculate the energies of all excited states in the large-N limit.Comment: LaTeX (iopart); 10 pages; to be published in J.

Do recruiters prefer applicants with similar skills? Evidence from a randomized natural experiment

In this paper we examine the potential existence of a similar-to-me effect in terms of skills between recruiters and applicants. Using evidence from entry exams to the Spanish Judiciary, where applicants are randomly assigned across evaluation committees, we find that committee members tend to be more demanding at those stages where they are more knowledgeable. As a result, applicants who excel in the same dimensions as recruiters are more likely to be hire
