3567. Structuring linguistic noise : The children's remarkable capacity for syntactic segmentationArthur Stepanov, predavanje na tuji univerzi Opis: How do young children acquiring their native language master complex abstract properties of adult sentences, more specifically, their syntactic structure? A good portion of recent research in child language acquisition is devoted to the nature of 'segmentation' strategies allowing children to deduce some of these abstract structural properties from the linguistic input they are exposed to, and the role of linguistic (e.g. prosodic), cognitive (e.g. working memory, probabilistic) and experience (e.g. bilingualism, music training) factors that affect the segmentation task. In this talk I give a broad outline of this research agenda including our own work and reflect on promising new directions that emerge in this domain.

3569. Au and Ag on the Bi2Se3(0001) Surface: Experimental Electronic and Physical PropertiesSandra Gardonio, Mattia Fanetti, Katja Ferfolja, Matjaž Valant, objavljeni povzetek znanstvenega prispevka na konferenci Opis: Binary bismuth chalcogenides, Bi2Se3 and Bi2Te3, have been extensively studied as reference topological
insulators (TIs). These materials are bulk insulators with topological surface states (TSS) crossing the
Fermi level. In contrast to conventional surface states of metals, the TSS are extremely robust
against local modifications at the surface, such as adsorbed adatoms, localized defects or changes in the surface termination. This aspect makes the TIs attractive for applications in spintronics, plasmonics, quantum computing and catalysis.
A theoretical model of charge transport by the TI surface states predicts that the TSS survive, provided that bonding at the metal/TI interface is weak. Ab-initio calculations have been done to understand the electronic properties of Au, Ni, Pt, Pd and graphene layers in a contact with Bi2Se3. These calculations showed that for Au and graphene the spin-momentum locking of TSS is maintained at the interface. In another theoretical study, Ag and Au thin layers on Bi2Se3 have been predicted to show a large Rashba splitting and a high spin polarization of the Ag quantum wells, providing a great potential for development of the spintronic devices. Finally, the calculations have foreseen that the presence of the robust TSS affects the adsorption properties of metals (Au bi-layer and clusters of Au, Ag, Cu, Pt, and Pd) supported on TI, in some cases resulting in the enhancement of the catalytic processes.
Despite the fundamental importance of the metal/TI interfaces and a number of theoretical studies
predicting exotic interfacial phenomena, the experimental knowledge about the metals on the TI surfaces is surprisingly limited, especially concerning combined study of morphology, growth mode, electronic and chemical properties.
In order to exploit the predicted physical properties of such systems, it is especially important to extend the study above the diluted coverage regime and to understand what is the growth morphology of the metal on the TI surface, to what extent the metal overlayer interacts with the TI substrate, how the TSS change with the presence of the metal overlayer and what is the reactivity of the system at the different stages of the overlayer growth.
Within this frame, we present a comprehensive surface sensitive study, of Au and Ag on Bi2Se3 by means of ARPES, XPS, SEM, LEED and XRD. The obtained results allow us to discuss the relation between electronic and physical properties at two of the most important model metal/TI interfaces
