Proposal of a new diffractive corneal inlay to improve near vision in a presbyopic eye

2020

[EN] A new class of diffraction-based corneal inlays for treatment of presbyopia is described. The inlay is intended to achieve an improvement of the near focus quality over previous designs. Our proposal is a two-zone hybrid device with separated amplitude and phase areas having a central aperture and no refractive power. An array of micro-holes is distributed on the surface of the inlay conforming a binary photon sieve. In this way, the central hole of the disk contributes to the zero order of diffraction, and the light diffracted by the micro-holes in the peripheral photon sieve produces a real focus for near vision. We employed ray-tracing software to study the performance of the new in…

Bibliotecas abiertas. El programa de visitas de la Biblioteca Valenciana Nicolau Primitiu. Información bibliográfica y difusión bibliotecaria. Biblio…

2022

En un contexto de reducción de la financiación pública y de cambio de paradigma en el acceso a la información, la supervivencia de las bibliotecas está ligada a un mayor y mejor conocimiento de la ciudadanía de sus colecciones, productos y servicios. En este estudio se analiza el programa de visitas de la Biblioteca Valenciana Nicolau Primitiu, sus características, destinatarios y tipologías, así como los resultados alcanzados hasta ahora. In a context of reduced public funding and a paradigm shift in access to information, the survival of libraries is linked to greater and better knowledge by citizens of their collections, products, and services. This study analyzes the visits program of t…

Digital Storytelling in Teacher Training: Development of Basic Competences, Creativity and Multimodal Literacy Through Book Trailers

2018

In this chapter, the need of the integration of media and information and communication technologies in the literary education is addressed, not only from the point of view of the training in access to information and diffusion, but also in terms of the communicative situations of production and reception of literary texts. In this sense, the authors analyze the potential of digital storytelling in teacher training as a tool for the acquisition and development of basics competences, the promotion of creativity and the adquisition of the multimodal literacy of students. This research focuses on the use of book trailers as a way to enhance reading habits acquisition and to make students disco…

Why Don't We Do What We Want? Non-Consumers and the Public Dilemma in Cultural Promotion

2005

We deal with tastes and preferences, revising the linkages between both in order to analyse the special case where we express preferences to goods that do not appeal to us. We deduce the concept of a deconstructed demand and define two types of goods (embarrassing and reputable). With the help of this structure we build a demand function for cultural promotion, where the non-market-expressed non-consumers' preferences are the basis of the demand for cultural policies. Finally, in this framework the State faces a dilemma that could be solved in different ways.

Capabilities of Ultrametric Automata with One, Two, and Three States

2016

Ultrametric automata use p-adic numbers to describe the random branching of the process of computation. Previous research has shown that ultrametric automata can have a significant decrease in computing complexity. In this paper we consider the languages that can be recognized by one-way ultrametric automata with one, two, and three states. We also show an example of a promise problem that can be solved by ultrametric integral automaton with three states.

Implications of quantum automata for contextuality

2014

We construct zero error quantum finite automata (QFAs) for promise problems which cannot be solved by bounded error probabilistic finite automata (PFAs). Here is a summary of our results: There is a promise problem solvable by an exact two way QFA in exponential expected time but not by any bounded error sublogarithmic space probabilistic Turing machine (PTM). There is a promise problem solvable by an exact two way QFA in quadratic expected time but not by any bounded error o(loglogn) space PTMs in polynomial expected time. The same problem can be solvable by a one way Las Vegas (or exact two way) QFA with quantum head in linear (expected) time. There is a promise problem solvable by a Las …

Statistical tools and control of internal lubricant content of inhalation grade HPMC capsules during manufacture

2016

The internal lubricant content (ILC) of inhalation grade HPMC capsules is a key factor to ensure good powder release when the patient inhales a medicine from a dry powder inhaler (DPI). Powder release from capsules has been shown to be influenced by the ILC. The characteristics used to measure this are the emitted dose, fine particle fraction and mass median aerodynamic diameter. In addition the ILC level is critical for capsule shell manufacture because it is an essential part of the process that cannot work without it. An experiment has been applied to the manufacture of inhalation capsules with the required ILC. A full factorial model was used to identify the controlling factors and from…

High resolution 80Se(n,γ) cross section measurement at CERN n_TOF and development of the novel i-TED detection system

2022

El proceso (-s) de captura lenta de neutrones es responsable de la formación de la mitad de los elementos más pesados ​​que el hierro en el universo. A pesar de la larga escala de tiempo de este proceso, la larga vida media de algunos isótopos inestables a lo largo del flujo de reacción del proceso-s crea puntos de ramificación que conducen a una división de la ruta de la nucleosíntesis. 79Se (t1/2 = 3.27 x 10^5 y) representa uno de los núcleos ramificados-s más relevantes y debatidos por dos razones principales. Por un lado, la existencia de estados excitados de baja energía en el 79Se, cuya población puede variar con la temperatura del medio estelar, hace que el patrón de abundancia local…
