Els diàlegs matrimonials de la casa de Borgonya i els emblemes amorosos al Tirant lo Blanc
2011
Les «invencions poètiques» o «lletres d'invenció» van complir un paper distintiu i ornamental, complementari del dels emblemes heràldics, que identificaven famílies o eren símbols d'afirmació política. L'estudi tracta de posar en relació el joc poètic i simbòlic de les divises i mots que Tirant i Carmesina, els protagonistes de la novel·la 'Tirant lo Blanc', duen brodats als vestits, amb tot un repertori d'intercanvis cortesos, igualment emblemàtics, entre personatges històrics de la més alta aristocràcia i reialesa europea. En concret, trobem el diàleg entre les divises de Tirant i Carmesina (algunes de les de Tirant semblants a les del rei Magnànim) inserit plenament dins la tradició borg…
3D nanoscale ordered architectures in thin films for organic electronics
2011
Order in molecular thin films is of fundamental importance to gain and exploit a series of properties in nanotechnology. In this contest, engineering 2D supramolecular and molecular superstructures is of particular interest. They offer great possibilities for several applications whose achievement also allows for new theoretical approaches and nanoscale laws [1]. A natural extension of 2D nanopatterning concerns the attainment of a 3D nanoscale control in molecular films [2]. This question is complex to challenge and it is of ultimate importance in emerging fields like organic and hybrid photovoltaics, organic thin film transistors and sensors as well as plastic electronics. For example, th…
Ecological Stoichiometry of Bumblebee Castes, Sexes, and Age Groups
2021
Ecological stoichiometry is important for revealing how the composition of chemical elements of organisms is influenced by their physiological functions and ecology. In this study, we investigated the elemental body composition of queens, workers, and males of the bumblebee Bombus terrestris, an important pollinator throughout Eurasia, North America, and northern Africa. Our results showed that body elemental content differs among B. terrestris castes. Young queens and workers had higher body nitrogen concentration than ovipositing queens and males, while castes did not differ significantly in their body carbon concentration. Furthermore, the carbon-to-nitrogen ratio was higher in ovipositi…
Operational sex ratio and resource defence as predictors of the mating system in European bitterling
2003
Operational sex ratio (OSR), the ratio of sexually active males to fertilizable females in a population, plays a central role in the theory of mating systems by predicting that the intensity of male–male competition and the degree of sexual selection increases as the OSR becomes increasingly male biased. At high values of OSR, however, resource defence theory predicts the breakdown of territoriality and a shift towards scramble competition with a decrease in sexual selection. The direction that correlations between OSR and resource competition and variance in mating success will take depends on the biology of the species of interest. We investigated the effects of male population density an…
Computations on non-covalent assemblies: Supramolecular organization and transport properties
2022
The aim of this Thesis is to rationalize, from a theoretical perspective, the structural, electronic, optical and transport properties of different electroactive non-covalent assemblies of special relevance in the field of organic electronics. The ultimate goal is to establish valuable supramolecular structure-property relationships. In particular, this Thesis is focused on three types of systems: hole transporting materials (HTM), donor–acceptor supramolecular complexes and supramolecular polymers. For each system, the spotlight has been put on different relevant electronic processes. In the first part, the structural organization of several supramolecular polymers is studied. In particula…
Nanodevices by DNA based gold nanostructures
2017
In this thesis DNA based structures were utilized to create gold nanostructures for nanosensing and nanoelectronic applications. In the past, both of these fields have been dominated by the conventional lithography methods, e.g., electron beam lithography and UV-lithography, but more recently scaling down the components by these techniques has become increasingly more complex and costly. Especially in the micro- and nanoelectronics, the increase in the component density and thus computational power would require fabrication of sub-10-nm components, which is challenging for the top-down approaches. Aforementioned developments have led researchers to seek alternative methods to fabricate these…
Cilium induction triggers differentiation of glioma stem cells
2020
Glioblastoma multiforme (GBM) possesses glioma stem cells (GSCs) that promote self-renewal, tumor propagation, and relapse. GBM has a poor prognosis, and currently, there are no curative options exist. Understanding the mechanisms of GSCs self-renewal can offer targeted therapeutic interventions. However, insufficient knowledge of the fundamental biology of GSCs is a significant bottleneck hindering these efforts. Here, we show that patient-derived GSCs recruit an elevated level of proteins that ensure the temporal cilium disassembly, leading to suppressed ciliogenesis. Depleting the cilia disassembly complex components at the ciliary base is sufficient to induce ciliogenesis in a subset of…
Cilium induction triggers differentiation of glioma stem cells.
2020
Glioblastoma multiforme (GBM) possesses glioma stem cells (GSCs) that promote self-renewal, tumor propagation, and relapse. Understanding the mechanisms of GSCs self-renewal can offer targeted therapeutic interventions. However, insufficient knowledge of GSCs' fundamental biology is a significant bottleneck hindering these efforts. Here, we show that patient-derived GSCs recruit elevated levels of proteins that ensure the temporal cilium disassembly, leading to suppressed ciliogenesis. Depleting the cilia disassembly complex components is sufficient to induce ciliogenesis in a subset of GSCs via relocating platelet-derived growth factor receptor-alpha (PDGFR-α) to a newly induced cilium. Im…
