Cette thèse a pour objectif la description et l'analyse des dynamiques de production et valorisation de l'identité Zafimaniry à partir de trois domaines différents: l'art ethnique, le patrimoine immatériel et le tourisme. Les ...
Zeb1 en las células estrelladas del páncreas: implicación en la oncogénesis pancreática dependiente de Kras
El factor de transcripción Zeb1 tiene un papel crucial en la oncogénesis mediada por Kras. En el adenocarcinoma ductal de páncreas (ACDP), Zeb1 muestra una elevada expresión en los miofibroblastos, la cual se correlaciona ...
Zeb1, un gen implicat en la repressió transcripcional de l'E-Cadherina durant la transició epiteli-mesènquima. Caracterització del mecanisme de regulació de la seva expressió
Durant la transició Epiteli-Mesènquima (TEM), el factor de transcripció Snail reprimeix la transcripció de l'E-cadherina unint-se a les caixes E presents en el promotor d'aquest gen.<br/>Les cèl·lules que expressen Snail ...
Zebrafish and mouse models for studying deubiquitinating enzyme genes as candidates for retinal dystrophies
The retina consists of several structured layers of highly specialized neurons that capture and process light stimuli enabling vision. Such a fine architecture turns retinal differentiation into an extremely complex event ...
Zebrafish lateral line system: The roles of Eya1 in migrating primordium and Notch signaling in hair cell development and regeneration
The purpose of this thesis is to introduce and demonstrate several biological processes or phenomena using posterior lateral line system of zebrafish as a model. The first part of this work focuses on the highly dynamic ...
ZeGRIN: Using zebrafish GRIN-related disorders models for disease understanding and therapeutic discovery
[eng] The glutamatergic neurotransmission system is crucial for brain function, and its dysregulation is involved in several neurological diseases, including developmental, psychiatric and neurodegenerative disorders. ...
Zen aesthetic: development and influence in culture and contemporary painting of China, Japan and USA = La estética Zen: desarrollo e influencia en la cultura y la pintura contemporánea de China, Japón y EE. UU
No other form of Oriental philosophy has had such a widespread, positive effect on culture and international contemporary painting as Zen Aesthetic. Owing to the birth of Zen Buddhism in China, its extraordinary boom and ...
Zeolitic imidazolate framework-8: control of particle size and shape and its self-assembly
Esta Tesis tiene como objetivo dar al lector una idea sobre las nuevas perspectivas abiertas en la manipulación controlada de Metal-Organic Frameworks con precisión nanométrica y sus consecuencias en las propiedades finales ...
Zero-field anisotropic spin hamiltonians in first-row transition metal complexes: theory, models and applications
Aquest treball presenta l’estudi teòric de l’anisotropia magnètica en complexos de metalls de transició, combinant esquemes de càlcul multiconfiguracionals relativistes amb derivacions analítiques basades en la teoria del ...
Zero-knowledge proofs and isogeny-based cryptosystems
In this thesis, we present some public-key cryptographic schemes. This work is divided in two halves. The rst half deals with zero-knowledge proofs in the classical setting and under falsi able assumptions. In particular, ...
Zero-knowledge proofs for self-sovereign identities in decentralized services
Telecommunication systems such as mobile communications are evolving over time, and thanks to that, many digital services have arisen in the last decade. Usually, these services ask their users to provide sensitive information ...
Zero-thickness interface elements in petroleum geomechanics : sand production and hydraulic fracture
This thesis describes the extension of the Finite Element Method with zero-thickness interface elements (FEM+z) to 3D, large and complex problems in geomaterials, with special interest in petroleum geomechanics. This general ...
Zero-touch service orchestration in 5G and beyond mobile networks
(English) The expeditious growth and development of Beyond-5G and 6G networks inaugurated a new sector in the research of cellular networking. Automation and scaling are now considered a necessity to cope with the anticipated ...
Zero-watermarking for data integrity, secure provenance and intrusion detection in IoT networks
This thesis explores the integration of advanced security techniques into Intrusion Detection Systems (IDS) for IoT networks, which face increasing cyber threats due to their interconnected nature and limited resources. ...
