Open/closed duality for FZZT branes in c=1

We describe how the matrix integral of Imbimbo and Mukhi arises from a limit of the FZZT partition function in the double-scaled c=1 matrix model. We show a similar result for 0A and comment on subtleties in 0B.Comment: 26 pages, 2 figure

Brane Inflation, Solitons and Cosmological Solutions: I

In this paper we study various cosmological solutions for a D3/D7 system directly from M-theory with fluxes and M2-branes. In M-theory, these solutions exist only if we incorporate higher derivative corrections from the curvatures as well as G-fluxes. We take these corrections into account and study a number of toy cosmologies, including one with a novel background for the D3/D7 system whose supergravity solution can be completely determined. This new background preserves all the good properties of the original model and opens up avenues to investigate cosmological effects from wrapped branes and brane-antibrane annihilation, to name a few. We also discuss in some detail semilocal defects with higher global symmetries, for example exceptional ones, that could occur in a slightly different regime of our D3/D7 model. We show that the D3/D7 system does have the required ingredients to realise these configurations as non-topological solitons of the theory. These constructions also allow us to give a physical meaning to the existence of certain underlying homogeneous quaternionic Kahler manifolds.Comment: Harvmac, 115 pages, 9 .eps figures; v2: typos corrected, references added and the last section expanded; v3: Few minor typos corrected and references added.

Current vision on diagnosis and comprehensive care in hepatic encephalopathy

The first clinical guidelines on hepatic encephalopathy were published in 2009. Almost 14 years since that first publication, numerous advances in the field of diagnosis, treatment, and special condition care have been made. Therefore, as an initiative of the Asociación Mexicana de Gastroenterología A.C., we present a current view of those aspects. The manuscript described herein was formulated by 24 experts that participated in six working groups, analyzing, discussing, and summarizing the following topics: Definition of hepatic encephalopathy; recommended classifications; epidemiologic panorama, worldwide and in Mexico; diagnostic tools; conditions that merit a differential diagnosis; treatment; and primary and secondary prophylaxis. Likewise, these guidelines emphasize the management of certain special conditions, such as hepatic encephalopathy in acute liver failure and acute-on-chronic liver failure, as well as specific care in patients with hepatic encephalopathy, such as the use of medications and types of sedation, describing those that are permitted or recommended, and those that are not. Resumen: La primera guía clínica sobre encefalopatía hepática se publicó en el año 2009, a casi catorce años de esta primera publicación, numerosos avances en el campo del diagnóstico, tratamiento y cuidados en condiciones especiales, han ocurrido; por ello, a iniciativa de la Asociación Mexicana de Gastroenterología A.C presentamos este manuscrito elaborado por 24 expertos que han trabajado en seis mesas de trabajo analizando, discutiendo y resumiendo los siguientes tópicos: Definición de encefalopatía hepática, clasificaciones que se recomiendan utilizar, panorama epidemiológico mundial y en México, herramientas para el diagnóstico, condiciones que ameritan hacer un diagnóstico diferencial, tratamiento y profilaxis primaria y secundaria. Así mismo, esta guía hace énfasis en el manejo de ciertas condiciones especiales como encefalopatía hepática en insuficiencia hepática aguda y en falla hepática aguda sobre crónica y cuidados específicos en pacientes con encefalopatía hepática como medicamentos que se deben evitar, por ejemplo, uso de analgésicos permitidos y no permitidos, y en caso de sedación para procedimientos cuales se permiten o sugieren y cuáles no
