Xalapa de Enriquez, Mexico

Universidad Veracruzana a public autonomous university located in the Mexican state of Veracruz. Established in 1944, the university is one of the most important in the south-east region of México and has a good projection in all México. Its academic organization is a structure based on academic areas, schools, education programs and research institutes. Due to geographic dispersing, academic activities are coordinated by the Academic Secretariat and four Vice-Rector’s Offices. General Directions of the academic areas: Arts, Biology and Agricultural science, Health science, Economics and Business Administration, Liberal Arts and Technical coordinate as well each school and educational programs. The Department of Research coordinates the plans and activities of the research institutes, and the Direction of Art Dissemination operates the artistic groups and the cultural activities programs.In the region of Xalapa, the University has 32 schools, 22 institutes and research centers, one Children’s Musical Induction Center, one Language Center, one Foreign Languages Department, two Self-access Language Learning Centers, two Arts Workshops, one Foreign Students School, one Advanced Technology Lab, one Analytic Resolution Support Services Unit, one School Hospital and one Library Services and Information Unit . In Veracruz: 13 schools, four institutes and research centers, one Children’s Musical Induction Center, one Language Center, two Self-access Language Learning Centers, one Art Workshops and one USBI. In Orizaba-Córdoba: 8 schools, two Language Centers, two Self-access Language Learning Centers and an Advanced Technology Lab. In Poza Rica: 13 schools, one Language Center, a Self-access Language Learning Center, and two Art Workshops. And in Coatzacoalcos-Minatitlán, 8 schools, one Language Center, two Self-access Learning Centers and two USBIs. Furthermore, it is associated with the North American Mobility Project, a transnational academic program that links it to Georgia Southern University in the United States and Wilfrid Laurier University in Canada.

The genetic and molecular basis of the developmental programs underlying adaptive morphological changes is largely unknown. A new study reveals an ancient gene that has been instrumental for the generation of morphological diversity and adaptation in land plants. © 2016 Elsevier Ltd. Source

Multiple steps are required to ensure compliance between Management of Marine Protected Areas in the Coastal Zone (MPACZ), and the objectives they were created for. Due to limited financial resources, there is an emerging necessity to identify priority actions that impact efficiently in the conservation objectives of the protected area. A simplified causal network analysis of the environmental problems of MPACZ is proposed in this paper as a tool for identifying those priority actions. This paper shows that management of an MPACZ is a complex task influenced by the origin and spatial location of the causes of environmental issues affecting it; the example case is the Sistema Arrecifal Veracruzano National Park in Mexico. Through the identification of 17 environmental problems and 50 causes that generate them, it was found that environmental impacts within a protected area may be due to many causes, whether human or natural, and that the choice of priority actions should be made considering causal relationships between them to achieve efficient use of available financial resources. © 2011 Elsevier Ltd.

Narcolepsy/hypocretin deficiency (now called type 1 narcolepsy) is a lifelong neurologic disorder with well-established diagnostic criteria and etiology. Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness (EDS) and symptoms of dissociated rapid eye movement sleep such as cataplexy (sudden loss of muscle tone), hypnagogic hallucinations (sensory events that occur at the transition from wakefulness to sleep), sleep paralysis (inability to perform movements upon wakening or sleep onset), and nocturnal sleep disruption. As these symptoms are often disabling, most patients need life-long treatment. The treatment of narcolepsy is well defined, and, traditionally, amphetamine-like stimulants (i.e., dopaminergic release enhancers) have been used for clinical management to improve EDS and sleep attacks, whereas tricyclic antidepressants have been used as anticataplectics. However, treatments have evolved to better-tolerated compounds such as modafinil or armodafinil (for EDS) and adrenergic/serotonergic selective reuptake inhibitors (as anticataplectics). In addition, night-time administration of a short-acting sedative, γ-hydroxybutyrate (sodium oxybate), has been used for the treatment for EDS and cataplexy. These therapies are almost always needed in combination with non-pharmacologic treatments (i.e., behavioral modification). A series of new drugs is currently being tested in animal models and in humans. These include a wide variety of hypocretin agonists, melanin-concentrating hormone receptor antagonists, antigen-specific immunopharmacology, and histamine H3 receptor antagonists/inverse agonists (e.g., pitolisant), which have been proposed for specific therapeutic applications, including the treatment of Alzheimer's disease, attention-deficit hyperactivity disorder, epilepsy, and more recently, narcolepsy. Even though current treatment is strictly symptomatic, based on the present state of knowledge of the pathophysiology of narcolepsy, we expect that more pathophysiology-based treatments will be available in the near future. © 2013 Springer International Publishing Switzerland.

The structure of the exact wave function of the isovectorial pairing Hamiltonian with nondegenerate single-particle levels is discussed. The way that the single-particle splittings break the quartet condensate solution found for N=Z nuclei in a single degenerate level is established. After a brief review of the exact solution, the structure of the wave function is analyzed and some particular cases are considered where a clear interpretation of the wave function emerges. An expression for the exact wave function in terms of the isospin triplet of pair creators is given. The ground-state wave function is analyzed as a function of pairing strength, for a system of four protons and four neutrons. For small and large values of the pairing strength a dominance of two-pair (quartets) scalar couplings is found, whereas for intermediate values enhancements of the nonscalar couplings are obtained. A correlation of these enhancements with the creation of Cooper-like pairs is observed. © 2010 The American Physical Society. Source

The Lipkin-Meshkov-Glick (LMG) model has a Schwinger boson realization in terms of a two-level boson pairing Hamiltonian. Through this realization, it has been shown that the LMG model is a particular case of the SU(1, 1) Richardson-Gaudin (RG) integrable models. We exploit the exact solvability of the model to study the behavior of the spectral parameters (pairons) that completely determine the wave function in the different phases, and across the phase transitions. Based on the relation between the Richardson equations and the Lamé ordinary differential equation we develop a method to obtain numerically the pairons. The dynamics of pairons in the ground and excited states provide new insights into the first, second and third order phase transitions, as well as into the crossings taking place in the LMG spectrum. © 2013 Elsevier B.V.
