The transcription factor NR2E3 participates in photoreceptor cell fate determination as it functions as both transcriptional repressor of cone genes and activator of rod genes. Mutations in NR2E3 cause retinitis pigmentosa ...
[eng] This doctoral thesis investigates the potential of third-party logistics (TPL) companies as key facilitators of collaborative systems and the implementation of the blue ocean strategy within the realm of supply chain ...
The work we present in this manuscript revolves around the use of quasar spectra to probe the Universe. Absorption features in the electromagnetic spectrum of bright distant quasars by ionized hydrogen give us access to ...
