A note on intraday option pricing [PDF]
, 2013 Compound renewal processes can be used as an approximate phenomenological model of tick-by-tick price fluctuations. An exact and explicit general formula is derived for the martingale price of a European call option written on a compound renewal process.

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Bringing phonological oddities to the fore: The Basque sibilants
Anuario del Seminario de Filología Vasca "Julio de Urquijo"The contrast between apical and laminal articulations in Basque dento-alveolar sibilant consonants has traditionally attracted linguists’ attention. This distributedness distinction, as it has come to be known in the literature, was assumed to be very ...

Cultural field and literature in minority languages: Basque under Francoism
Poetics, 2019 The concept of the cultural field allows us to address the emergence of literatures in minority languages before these literatures can constitute autonomous fields. Located within a broader dialogue involving different expressions of culture, the concept of the cultural field requires that one considers the field’s relationship to different sources of ...

A Functional 2D Carbon Allotrope Combining Nanoporous Graphene and Biphenylene Segments
Advanced Materials, EarlyView.The synthesis of a novel nanoporous graphene (NPG) is reported with biphenylene segments via thermal fusion of 12‐armchair porous graphene nanoribbons grown on gold surfaces. Characterization using STM, AFM, and DFT reveals low‐defect semiconducting behaviour and tunable band gaps.

Advanced Materials, EarlyView.This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Recueils manuscrits de chansons basques
Anuario del Seminario de Filología Vasca "Julio de Urquijo", 1988 This article aims at highlighting the necessity of publishing the indexes of the handwritten song-books to be found in both public and private collections, since these indexes may be of use to researchers in the field of oral Basque literature.
