Características clínicas predominantes del trastorno compulsivo canino

Problemas como el lamido excesivo de los miembros, la persecución con mordisqueo del apéndice caudal y la deambulación estereotipada en caninos domésticos, actualmente son considerados comportamientos anormales, excesivos en duración, frecuencia e intensidad, relativamente invariables y sin beneficio para el individuo o la especie (compulsiones). Surgen tanto en ambientes hipoestimulantes como hiperestimulantes y no se identifican estímulos disparadores. Se ha demostrado que la disfunción afecta a varios sistemas de neurotransmisores (dopamina, serotonina, noradrenalina y opioides endógenos) y el sistema de regulación intracelular de segundos mensajeros

Fundamentals of Multi-User MIMO Communications

In recent years, the remarkable promise of multiple-antenna techniques has motivated an intense research activity devoted to characterizing the theoretical and practical issues associated with multiple-input multiple-output wireless channels. This activity was first focused primarily on single-user communications but more recently there has been extensive work on multi-user settings. The aim of this chapter is to provide an overview of the fundamental information-theoretic results and practical implementation issues of multi-user multiple-antenna networks operating under various conditions of channel state information

Health governance of COVID-19 in Milan and Toronto: long-term trends and short-term failures

In this paper, we examine a crisis in the governance of health and care that characterized the regions of Milan and Toronto, which the COVID-19 pandemic impacted substantially—both in early 2020 when SARS-CoV-2 first hit and later in the fall and winter when the disease entered its second and third waves. We analyze restructuring in health and care in both regions, and, where necessary, in national contexts. We make the case that restructuring and implementing welfare and health policy, includ- ing long-term care, in Toronto and Milan in the context of long- standing tendencies of health governance restructuring that were part of a more general rescaling of the regional welfare state be held responsible for the toll COVID-19 levied
