The Linear Ordering Problem Revisited

The Linear Ordering Problem is a popular combinatorial optimisation problem which has been extensively addressed in the literature. However, in spite of its popularity, little is known about the characteristics of this problem. This paper studies a procedure to extract static information from an instance of the problem, and proposes a method to incorporate the obtained knowledge in order to improve the performance of local search-based algorithms. The procedure introduced identifies the positions where the indexes cannot generate local optima for the insert neighbourhood, and thus global optima solutions. This information is then used to propose a restricted insert neighbourhood that discards the insert operations which move indexes to positions where optimal solutions are not generated. In order to measure the efficiency of the proposed restricted insert neighbourhood system, two state-of-the-art algorithms for the LOP that include local search procedures have been modified. Conducted experiments confirm that the restricted versions of the algorithms outperform the classical designs systematically. The statistical test included in the experimentation reports significant differences in all the cases, which validates the efficiency of our proposal.

La Guerra de la Convención, la separación de Guipúzcoa y los comerciantes vasco-franceses y bearneses

[ES] El intento de separación de Guipúzcoa de la Corona española durante la Guerra de la Convención (1793-1795) es un asunto en el que se vio implicado un numeroso grupo de comerciantes vascofranceses y bearneses, residentes en San Sebastián desde hacía tiempo. Los estudiosos han explicado su impli- cación desde parámetros ideológicos y políticos. Sin embargo, existió tam- bién un componente económico y familiar, que tuvo más peso que el resto de factores. Es precisamente este componente el objeto de estudio del presente artículo.

Ca2+ Influx and Tyrosine Kinases Trigger Bordetella Adenylate Cyclase Toxin (ACT) Endocytosis. Cell Physiology and Expression of the CD11b/CD18 Integrin Major Determinants of the Entry Route

Humans infected with Bordetella pertussis, the whooping cough bacterium, show evidences of impaired host defenses. This pathogenic bacterium produces a unique adenylate cyclase toxin (ACT) which enters human phagocytes and catalyzes the unregulated formation of cAMP, hampering important bactericidal functions of these immune cells that eventually cause cell death by apoptosis and/or necrosis. Additionally, ACT permeabilizes cells through pore formation in the target cell membrane. Recently, we demonstrated that ACT is internalised into macrophages together with other membrane components, such as the integrin CD11b/CD18 (CR3), its receptor in these immune cells, and GM1. The goal of this study was to determine whether ACT uptake is restricted to receptor-bearing macrophages or on the contrary may also take place into cells devoid of receptor and gain more insights on the signalling involved. Here, we show that ACT is rapidly eliminated from the cell membrane of either CR3-positive as negative cells, though through different entry routes, which depends in part, on the target cell physiology and characteristics. ACT-induced Ca2+ influx and activation of non-receptor Tyr kinases into the target cell appear to be common master denominators in the different endocytic strategies activated by this toxin. Very importantly, we show that, upon incubation with ACT, target cells are capable of repairing the cell membrane, which suggests the mounting of an anti-toxin cell repair-response, very likely involving the toxin elimination from the cell surface.

Calpain-Mediated Processing of Adenylate Cyclase Toxin Generates a Cytosolic Soluble Catalytically Active N-Terminal Domain

Bordetella pertussis, the whooping cough pathogen, secretes several virulence factors among which adenylate cyclase toxin (ACT) is essential for establishment of the disease in the respiratory tract. ACT weakens host defenses by suppressing important bactericidal activities of the phagocytic cells. Up to now, it was believed that cell intoxication by ACT was a consequence of the accumulation of abnormally high levels of cAMP, generated exclusively beneath the host plasma membrane by the toxin N-terminal catalytic adenylate cyclase (AC) domain, upon its direct translocation across the lipid bilayer. Here we show that host calpain, a calcium-dependent Cys-protease, is activated into the phagocytes by a toxin-triggered calcium rise, resulting in the proteolytic cleavage of the toxin N-terminal domain that releases a catalytically active "soluble AC''. The calpain-mediated ACT processing allows trafficking of the "soluble AC'' domain into subcellular organella. At least two strategic advantages arise from this singular toxin cleavage, enhancing the specificity of action, and simultaneously preventing an indiscriminate activation of cAMP effectors throughout the cell. The present study provides novel insights into the toxin mechanism of action, as the calpain-mediated toxin processing would confer ACT the capacity for a space- and time-coordinated production of different cAMP "pools'', which would play different roles in the cell pathophysiology.

Cultura y creatividad en la nueva economía urbana: evidencias, discursos y críticas

En la medida en que el papel de los sectores cultural, artístico y creativo en el desarrollo económico y social de las ciudades-región comienza a ser ampliamente reconocido gracias a las progresivas evidencias empíricas recogidas en los últimos años sobre su importante capacidad de dinamismo, innovación y conectividad global, las intervenciones de las diferentes administraciones públicas y agentes privados en este ámbito también han ido en aumento. Una vez que el sector industrial ha declinado de forma drástica y otras actividades terciarias de la economía urbana se encuentran estancadas o en declive (comercio, consultoría, servicios inmobiliarios, etc.), las formas de producción y trabajo cognitivo-culturales son crecientemente señaladas como grandes impulsoras de la regeneración urbana, el posicionamiento global de las ciudades-región, la creación de empleo y la conexión con las vanguardias culturales. Si bien este proceso está facilitando una mayor visibilidad, apoyo y reconocimiento a las industrias y agentes culturales, artísticos y creativos que tradicionalmente han sufrido de forma intensa la precariedad, la baja o inexistente remuneración y la escasa valoración, también está propiciando una irrupción de las lógicas de mercado en ámbitos que hasta el momento han estado parcialmente desmercantilizados. Ello está generando diversas tensiones que afectan de forma destacada a la definición y el papel social y económico de la cultura en las ciudades.
