Beyond Hunting Camps: Early Holocene Occupations in High Cantabrian Mountains (Spain)
1998
En la comunicación se presentan los resultados de las excavaciones en el abrigo de La Calvera (Camaleño, Cantabria) incluyendo un conjunto de nuevas dataciones radiocarbónicas y se hace una reflexión sobre la ocupación de las montañas cantábricas al comienzo del Holoceno. In the communication the results of the excavations in La Calvera rock shelter (Camaleño, Cantabria) are presented, including a set of new radiocarbonic dates and a reflection is made on the occupation of the Cantabrian mountains at the beginning of the Holocene.
The Romanian Academic Novel and Film through the Postcommunism/Postcolonialism Lens
2019
The last two decades have witnessed an intensified academic interest in a potential rapprochement between Postcolonial Studies and Postcommunist Studies, the former a firmly established discipline in global academia, while the existence of the latter as a discipline in its own right is still debatable. As the possibility of this alliance is – as was to be expected – both contested and supported by various scholars, this article attempts to investigate this issue as illustrated by the postcommunist Romanian academic novel. Aware as it is of contemporary intellectual debates, the genre of the academic (or campus) novel seems particularly suitable for shedding light on the matter: academic fic…
Data from: Key roles for freshwater Actinobacteria revealed by deep metagenomic sequencing
2014
Freshwaters ecosystems are critical but fragile environments directly affecting society and its welfare. However, our understanding of genuinely freshwater microbial communities, constrained by our capacity to manipulate its prokaryotic participants in axenic cultures, remains very rudimentary. Even the most abundant components, freshwater Actinobacteria, remain largely unknown. Here, applying deep metagenomic sequencing to the microbial community of a freshwater reservoir, we were able to circumvent this traditional bottleneck and reconstruct de novo seven distinct streamlined actinobacterial genomes. These genomes represent three new groups of photoheterotrophic, planktonic Actinobacteria…
Second order nonlinear optics in AlGaAs metasurfaces
2023
Recently, nonlinear optics at the nanoscale level has emerged as a promising branch of nanophotonics. In this work, we focus our attention on Aluminum Gallium Arsenide (AlGaAs) nanoantennas and metasurfaces for efficient and controlled second harmonic photon emission. After a brief introduction concerning the main studies in this field, we present the latest results achieved in AlGaAs platforms both in the lossless and absorption regimes.
Fundamental limits for transmission modulation in VO2 metasurfaces
2022
The interest in dynamic modulation of light by ultra-thin materials exhibiting insulator–metal phase transition, such as VO 2 , has rapidly grown due to the myriad industrial applications, including smart windows and optical limiters. However, for applications in the telecommunication spectral band, the light modulation through a thin VO 2 film is low due to the presence of strong material loss. Here, we demonstrate tailored nanostructuring of VO 2 to dramatically enhance its transmission modulation, reaching a value as high as 0.73, which is 2 times larger than the previous modulation achieved. The resulting designs, including free-topology optimization, demonstrate the fundamental limit i…
Manipulating Light with Tunable Nanoantennas and Metasurfaces
2022
The extensive progress in nanofabrication techniques enabled innovative methods for molding light at the nanoscale. Subwavelength structured optical elements and, in general, metasurfaces and metamaterials achieved promising results in several research areas, such as holography, microscopy, sensing and nonlinear optics. Still, a demanding challenge is represented by the development of innovative devices with reconfigurable optical properties. Here, we review recent achievements in the field of tunable metasurface. After a brief general introduction about metasurfaces, we will discuss two different mechanisms to implement tunable properties of optical elements at the nanoscale. In particular…
Zināšanas Vitgenšteina “Filosofiskajos pētījumos” un “Par drošticamību”
2017
Maģistra darba mērķis ir, aplūkojot Vitgenšteina zināšanu izpratni “Filozofisko pētījumu” periodā un darbā “Par drošticamību”, argumentēt par labu idejai, ka darbā “Par drošticamību” Vitgenšteins nenovēršas no savas iepriekšējās filozofijas izpratnes. Darbā tiek aizstāvēts uzskats, ka Vitgenšteins, pretēji noteiktu interpretētāju apgalvojumiem, arī darbā “Par drošticamību”, pievēršoties zināšanu problēmai, saglabā savas metodiskās nostādnes. Darbā izpētīta Vitgenšteina filozofijas metodes izpratne, aplūkots un salīdzināts zināšanu problēmas risinājums abos darbos, kritizētas interpretācijas, kuras aizstāv filozofijas izpratnes maiņas ideju Vitgenšteina filozofijā, kā arī šo interpretāciju v…
Theoretical Approaches on Successful Email Marketing Campaigns
2016
Nowadays, the consumer has extremely varied product options. E-mail marketing could be atool to complement traditional marketing activities by increasing customer engagement, and whichdoes not involve high costs. While there have been many predictions for years that email marketing will be replaced withsomething else, it remained one of the most useful ways to reach current and potential customers. This paper aims to bring some clarifications on what could bring success to email marketingcampaigns. Responses are related to how sent emails can draw the attention of people (ie how theycan be observed), given that, users’ inboxes are invaded by messages of all kinds, how to measurethe results …
L’impacte social de la mobilitat humana. Una visió no dicotòmica del canvi cultural i individual
2014
Aquest article reflexiona sobre el balanc de costos/beneficis en les societats, tant emissores de poblacio com receptores, i en les persones que les componen. Es treballa en tot moment des de la doble perspectiva grupal/individual. Es descriu el proces dinamic de canvi i l’impacte del canvi cultural i individual produit per l’aculturacio. Tot aco esguitat per algunes reflexions sorgides d’una societat nomada com la nostra.
