La eficacia del aprendizaje perceptual como tratamiento de la ambliopía en la infancia, frente a otros tratamientos convencionales
2019
La ambliopía es un trastorno asociado con respuestas anormales del ojo afectado en la corteza visual (Mansouri, Thompson y Hess, 2008) que reduce la agudeza visual (AV) y afecta la percepción espacial de objetos y movimientos. La oclusión, que cubre el ojo dominante, es el tratamiento clásico. El aprendizaje perceptivo ha mostrado resultados positivos, pero se necesitan más estudios a nivel visuo perceptivo, psicomotor y psicoeducativo. Objetivo Analizar el efecto del tratamiento en niños de 4 a 12 años de edad, en términos de AV, estereopsis, sensibilidad de contraste (CS), habilidades visuales-perceptuales, psicomotores y aspectos psicosociales y escolares. Los tratamientos estudiados son…
Expansion and Compression of a Helicate with Central Diol-Units as Stereocontrolling Moieties
2022
The dicatechol ester ligand 2-H4 forms the compressed helicate Li4[(2)3Ti2] which upon removal of the internally bound lithium cations expands. In the compressed form, the chiral diol units control the stereochemistry of the complex which is lost upon expansion of the system. peerReviewed
Organocatalytic approach to benzofused nitrogen-containing heterocycles: enantioselective total synthesis of (+)-angustureine.

Recognition of alkali metal halide contact ion pairs by uranyl-salophen receptors bearing aromatic sidearms. The role of cation-pi interactions.
2005
Hard anions have long been known to bind strongly to the uranium of uranyl-salophen complexes. Upon functionalization of the salophen framework with one or two benzyloxy substituents, efficient ditopic receptors for alkali metal ions are obtained. The solid-state structures of complexes formed by the two-armed receptor 1 with CsF and with the chlorides of K+, Rb+, and Cs+ reported here reveal the existence of dimeric supramolecular assemblies in which two receptor units assemble into capsules fully enclosing (MX)2 ion quartets. In addition to the strong coordinative binding of the anion to the uranyl center and to electrostatic cation-anion interactions, stabilizing interactions arise from …
Obraz Rossii v polʹskih demotivatorah
2017
Demotivators are Internet hybrid texts, which reflect Internet users’ attitudes to politics, culture, sport, more or less famous individuals, and nations. A common topic expressed with demotivators is Russia and the Russians. However, the images of Russia projected by such demotivators are frequently stereotypical and negative, while graphic images employed in the Russian-themed hybrid texts can be classified into several categories. The first group constitutes images adhering to the underlying idea that “Russia is not a country; it is a state of mind”. These demotivators copy the content of the Russian Internet that depicts Russia as a country of absurdity, nonsense and poverty. Another gr…
Nörttikulttuurin identiteettikriisi : Gamergate, Comicsgate ja Star Wars poliittisten kiistojen näyttämöinä
2020
Nörttikulttuuri on identiteettikriisissä. Perinteisesti nörttimäisinä pidetyt käytänteet ja kulttuurituotteet ovat siirtyneet lähemmäs valtavirtaa, mikä on häivyttänyt rajaa nörttien ja muiden median ja teknologian käyttäjien välillä. Nörttikulttuurin sisälle tämä on heijastunut kiistaksi siitä, kuka saa osallistua nörttikulttuurin kuluttamiseen, tuottamiseen ja määrittelyyn, ja millä tavoin. Stereotypia nörttikulttuurista valkoisten heteromiesten maskuliinisena kenttänä ei koskaan ole pitänyt täysin paikkansa, mutta 2000-luvulla väitteen totuudellisuus on murentunut entisestään. Tässä artikkelissa tarkastelemme nörttiyden kriisiä kolmen tapaustutkimuksen kautta ja analysoimme, mitä Gamerga…

FPI Based Hyperspectral Imager for the Complex Surfaces : Calibration, Illumination and Applications
2022
Hyperspectral imaging (HSI) applications for biomedical imaging and dermatological applications have been recently under research interest. Medical HSI applications are non-invasive methods with high spatial and spectral resolution. HS imaging can be used to delineate malignant tumours, detect invasions, and classify lesion types. Typical challenges of these applications relate to complex skin surfaces, leaving some skin areas unreachable. In this study, we introduce a novel spectral imaging concept and conduct a clinical pre-test, the findings of which can be used to develop the concept towards a clinical application. The SICSURFIS spectral imager concept combines a piezo-actuated Fabry–Pé…
Restoration and Enhancement of Historical Stereo Photos
2021
Restoration of digital visual media acquired from repositories of historical photographic and cinematographic material is of key importance for the preservation, study and transmission of the legacy of past cultures to the coming generations. In this paper, a fully automatic approach to the digital restoration of historical stereo photographs is proposed, referred to as Stacked Median Restoration plus (SMR+). The approach exploits the content redundancy in stereo pairs for detecting and fixing scratches, dust, dirt spots and many other defects in the original images, as well as improving contrast and illumination. This is done by estimating the optical flow between the images, and using it …
