The Dynamic of Innovation Networks: A Switching Model on Technological Change

2012

In this paper we introduce an agent-based model with heterogeneous firms which compare their mutual innovation strategies on different network structures. By implementing a dynamic behavioral switching via a fitness mechanism based on agents performance, companies can endogenously modify their tactics of technological change and switch among three groups: stand-alone innovators, collaborative innovators and imitators. We focus the analysis on the impact of these three innovation categories on micro, meso and macro aggregates. Our findings show that collaborative companies are those having the highest positive impact on the economic system. Moreover, we study the properties of the emerging n…

Perception, Normativity and Action in Contemporary Philosophy of Mind and Cognitive Science

Working on the background of a view of mind as “in action”, as pragmatically shaped by its own dynamic interactions with the world, emerging from the achievements of contemporary philosophy of mind (from Searle to enactivism)and cognitive science (from Gibson to Goodale and Milner)I aim to propose a view of perception as a form of human activity of which we are responsible, and in which our “commitment” to truth and rationality can take place. Against some recent phenomenalist and antirepresentationalist views of perception I'll try to show that the action-oriented character of perception does not challenge its rational constraint to a right representation of the state of affairs which it i…

Theoretical morphology of tetrapod skull networks

2014

Abstract Network models of the tetrapod skull in which nodes represent bones and links represent sutures have recently offered new insights into the structural constraints underlying the evolutionary reduction of bone number in the tetrapod skull, known as Williston's Law. Here, we have built null network model-derived generative morphospaces of the tetrapod skull using random, preferential attachment, and geometric proximity growth rules. Our results indicate that geometric proximity is the best null model to explain the disparity of skull structures under two structural constraints: bilateral symmetry and presence of unpaired bones. The analysis of the temporal occupation of this morphosp…

Size dependent light absorption modulation and enhanced carrier transport in germanium quantum dots devices

2015

Quantum confinement in closely packed arrays of Ge quantum dots (QDs) was studied for energy applications. In this work, we report an efficient tuning mechanism of the light harvesting and detection of Ge QDs. Thin films of SiGeO alloys, produced by rf-magnetron sputtering, were annealed at 600 degrees C in N-2 to induce precipitation of small amorphous Ge QDs into the oxide matrix. Varying the Ge content, the QD size was tailored between 2 and 4 nm, as measured by high resolution transmission electron microscopy. X-ray photoelectron spectroscopy (XPS) measurements indicate the formation of pure SiO2, as well as the presence of a sub-stoichiometric Ge oxide shell at the QD interface. Light …

Quantifying preferential trading in the e-MID interbank market

2015

Interbank markets allow credit institutions to exchange capital for purposes of liquidity management. These markets are among the most liquid markets in the financial system. However, liquidity of interbank markets dropped during the 2007-2008 financial crisis, and such a lack of liquidity influenced the entire economic system. In this paper, we analyze transaction data from the e-MID market which is the only electronic interbank market in the Euro Area and US, over a period of eleven years (1999-2009). We adapt a method developed to detect statistically validated links in a network, in order to reveal preferential trading in a directed network. Preferential trading between banks is detecte…

Preferential CO oxidation over catalysts with well-defined inverse opal structure in microchannels

2008

Catalyst supports of CeO 2 /SiO 2 and Al 2 O 3 with three-dimensionally ordered macroporous structure were fabricated in microchannels by application of PMMA opals as templates. Pt-Rh supported on CeO 2 /SiO 2 showed high efficiency for CO removal in preferential CO oxidation in the presence of excess hydrogen. Pt-Rh supported on Al 2 O 3 with an inverse opal structure showed higher reactivity than that supported on wash-coated Al 2 O 3 layers in microchannel reactor.

DOWN SYNDROME AND REFERENTIAL COMMUNICATION:  UNDERSTANDING AND PRODUCTION

2011

Children with Down Syndrome (DS) have a delay that affects the global motor development, cognitive, communicative and linguistic. From the literature shows that these subjects follow the same general line of language acquisition of children with typical development, although their language remains behind their non-verbal cognitive abilities and then proceed with a slower. In our study we have set ourselves the objective to investigate some critical dimensions of the communicative function in particular, referential communication, which means the subject's ability to produce messages "referentially oriented”, or messages that allow the listener to recognize the immediacy of contact with the …

Mapping, understanding and predicting soil microbial diversity across France

2018

International audience; Microorganisms are extremely abundant and diverse in soils. Their huge diversity is central in soil functioning regarding the diversity of functions it supports (mineralization, detoxification, stability of soil…) and is more and more studied, especially in a context of increasing pressure on soil resources. Conversely to macroorganisms whose distribution on a wide scale has been studied for over a century, spatial scaling and determinism distribution of soil microorganisms on nationwide scale still needs to be documented, notably to decipher the environmental filters shaping these communities. communities were investigated at the scale of France to characterize thei…
