The main objectives of this work are:<br/>a) To test the predictions of suppressed-recombination chromosomal speciation models on two different lineages of mammals: rodents and rimates. Suppressed-recombination chromosomal ...
Protein-DNA interactions are indispensable players in the daily activities of cells. DNA-binding proteins regulate gene expression and are responsible of DNA replication, packaging, repair and recombination. Among them, ...
Proteins are involved in almost all cell processes, with physical interaction between them being key to their function and dictated by its 3D structure. Hence, the study of protein-protein interactions and protein-protein ...
La evaluación de las experiencias extendidas en el tiempo se puede hacer de muchas formas. El paradigma --hedometer' en economía sugiere que la evaluación global de la experiencia se puede explicar por las impresiones de ...
Tumors are composed of fast-growing cells that become malignant under selection of biological functions needed for cancer development. In this thesis, I intend to uncover the basic evolutionary principles underlying cancer ...
La música està present en totes les cultures. Tot i tenir les mateixes habilitats auditives, la manera en la què experimentem la música depèn del context cultural, la música que escoltem en el dia a dia o si hem rebut ...
This thesis develops normative arguments about nationalism in multinational contexts. It draws consequences from the arguments used by advocates of nationalism, and analyzes their implications for a theory of the multinational ...

The role of epistasis – inter-dependent contributions of alleles to fitness – in shaping genetic variation within and between populations is an important question in evolutionary biology with significant implications for ...
Models of speech perception differ in the nature of the relationship between speech perception and production. Whether speech perception and production processes are based on a common representations ̶ the articulatory ...
Per tal d'estudiar la relació complexa entre l'estructura d'un circuit genètic i la seva funció, ens centrem en estudiar dues proprietas: la seva capacitat evolutiva i la seva multi-functionalitat. Primer, fins a quin punt ...
Proteins are indispensable players in virtually all biological events. The functions of proteins are determined by their three dimensional (3D) structure and coordinated through intricate networks of protein-protein ...
Esta tesis está centrada en el estudio de mercados bilaterales en los cuales la comunicación no es completa, sino que viene dada por una red de comunicación. Las principales preguntas formuladas en la tesis son determinar ...
Esta investigación analiza el discurso de cuatro ONGs ecologistas con sede en España —Greenpeace, WWF, Amigos de la Tierra y Ecologistas en Acción— con relación al negacionismo ideológico del cambio climático desde el 2004 ...
There are several reasons why politics is the most discussed topic on Nigeria’s and perhaps Africa’s largest online discussion forum, Nairaland. As Nigeria grows in its population and digital landscape, including with ...
Portable and interactive technologies are changing the nature of collaborative learning practices. Learning can now occur both in and beyond the classroom and furthermore combine formal and informal activities monitored ...
Concluir la guerra de Sucesión española supuso un ingente esfuerzo que obligó al gobierno de Robert Harley a usar todos los medios a su alcance. El presente trabajo estudia los movimientos diplomáticos y las estrategias ...
This dissertation argues that the deadlock that constitutional courts find themselves in when justifying decisions on cases that involve conflicting constitutional norms can be best resolved by appealing to a particular ...
Motion estimation plays a key role in many of the image processing and computer vision problems. This thesis addresses the problem of recovering a dense motion field from a scene through the Calculus of Variations. In ...
Esta tesis trata sobre cómo la autoridad fiscal debe fijar los impuestos distorsivos de manera óptima. El capítulo 1 analiza el problema de la política fiscal cuando el gobierno tiene un incentivo a hacer default con su ...
