Augmented reality based middle and inner ear surgical procedures

2020

Otologic procedures involve manipulation of small, delicate and complex structures in the temporal bone anatomy which are in close proxmity of critical nerves and blood vessels. Augmented reality (AR) can highly benefit the otological domain by providing supplementary anatomical and navigational information unified on a single display. However, despite being composed of mainly rigid bony structures, the awareness and acceptance of possibilities of AR systems in otology is fairly low. This project aims at developing video-based AR solutions for middle and inner ear surgical procedures.We propose two applications of AR in this regard. In the first application, information about middle ear cle…

La asimilación de Barba Azul con la figura del tirano en las obras de Perrault y Bartók

2011

De acuerdo con Paul Ricoeur, se puede acceder a toda relación simbólica desde tres diferentes niveles de comprensión; a saber, uno cósmico, uno onírico y uno poético. El estudio de cada uno de ellos aportará una serie de directrices que, puestas en común con las restantes, permitirán la observación de rasgos análogos y sintomáticos en el texto trabajado, lo que posibilitará comprender, más allá de cuanto en la narración resulta explícito, aquello que permanece en la oscuridad del proceso formativo. Aplicaremos estas propuestas sobre el Barba Azul de Perrault para confrontarlas con la obra homónima de Bartók y desvelar, de este modo, las sorprendentes asimilaciones encontradas entre el señor…

Grade repetition at primary school level "CP"

2005

This research on the grade retention to the CP erects a detailed inventory of the knowledge on this question which gives rise to the more of animated discussions between the researchers and the teachers, and this since a long time. By allying the historic, comparative, economical and educational approaches, she conveys principal empirical results attached to the many facets of this measure that is more than an educational done. The empirical contribution of this study is based on a longitudinal followed during two years about more than three thousand students on CP in public schools of the French department of the Côte d'Or. We highlight that the grade retention are received favourably by t…

Responses of European lobster (Homarus gammarus) and lobster fishers to protective management

2017

Master's thesis Aquatic Ecology BIO500 - University of Agder 2017 Marine protected areas (MPAs) are valued for their conservation benefits to harvested species. However, potential benefits of MPAs to neighboring fisheries are less well-understood. This study quantifies how the European lobster (Homarus gammarus) and the fishery for this valued catch respond to the establishment of a relatively small (5.2 km2) MPA on the Norwegian Skagerrak coast. A series of yearly standardized trap surveys was conducted to estimate lobster abundance and catch weights both inside and outside the MPA before (2010- 2011) and after the MPA was established (2012-2016). Lobster abundance and catch weights were d…

A note on boundary conditions for nonlinear operators

2008

We investigate boundary conditions for strict-$\psi$-contractive and $\psi$-condensing operators. We derive results on the existence of eigenvectors with positive and negative eigenvalues and we obtain fixed point theorems for classes of noncompact opera\-tors.

Murine Model of Cytomegalovirus Latency and Reactivation

2008

Efficient resolution of acute cytopathogenic cytomegalovirus infection through innate and adaptive host immune mechanisms is followed by lifelong maintenance of the viral genome in host tissues in a state of replicative latency, which is interrupted by episodes of virus reactivation for transmission. The establishment of latency is the result of aeons of co-evolution of cytomegaloviruses and their respective host species. Genetic adaptation of a particular cytomegalovirus to its specific host is reflected by private gene families not found in other members of the cytomegalovirus group, whereas basic functions of the viral replicative cycle are encoded by public gene families shared between …

P3‐039: Axonal neuritic pathology induces early presynaptic alterations in ps1/APP Alzheimer's mice hippocampus

2011

Loss of neurons in the hippocampus correlates with memory impairment in AD. Significant early reduction in the numerical density of hippocampal SOM interneurons was found in single (APPswe) and double (APPswe/ PS1dE9 and APPswe/TauP301S-G272V) transgenic models based on APP over expression and amyloid production. However, this inhibitory population was unaffected in age-matched single PS1 and tau transgenic mice as well as nontransgenic controls. Whereas SOM neuron loss in APPswe/PS1dE9 was associated to the onset of extracellular amyloid pathology in double APP/ tau mice this loss preceded plaque formation. Conclusions: As in human AD, somatostatin cell loss is a common early pathological …

Songs in passerine birds are important for territory defense and mating. Speciation rates in oscine passerines are so high, due to cultural evolution, that this bird lineage makes up half of the extant bird species. Leaf warblers are a speciose Old-World passerine family of limited morphological differentiation, so that songs are even more important for species delimitation. We took 16 sonographic traits from song recordings of 80 leaf warbler taxa and correlated them with 15 potentially explanatory variables, pairwise, and in linear models. Based on a well-resolved molecular phylogeny of the same taxa, all pairwise correlations were corrected for relatedness with phylogenetically independe…

Aesthetic Political Thought: Benjamin and Marker Revisited

2003

The complexity of contemporary political life has challenged traditional political theory in several Western democracies. With the emergence of new approaches to the interpretation of political praxis, we are forced to confront issues such as the New Right, the Christian Right, communitarianism, post-liberalism, post-colonialism, post-Marxism, feminism, globalization, and green thought. Many of these approaches continue to both reflect and critically challenge major ideological movements dating back to the beginning of the twentieth century. Since alterations to earlier theories are commonly the result of changes in political, cultural, and social conditions, new approaches to understanding…
