Interactions between cholinergic and fibroblast growth factor receptors in brain trophism and plasticity
2014
Acetylcholine, acting on both nicotinic receptors (nAChRs) and muscarinic receptors (mAChRs), plays a role in the regulation of synaptic plasticity, being involved in the regulation of cellular processes and cognitive functions, such as learning, memory and attention. Recently, G protein coupled receptors (GPCRs), including mAChRs, have been reported to transactivate tyrosine-kinase receptors (RTK), such as epidermal growth factor receptor (EGFR), and initiate their intracellular signaling. In this minireview we have first analysed the RTK transactivation mechanisms, involving cholinergic receptors, and thereafter the interplay between AChR and neurotrophic factor systems built up by FGF2 a…
Banach spaces where convex combinations of relatively weakly open subsets of the unit ball are relatively weakly open
2018
We introduce and study Banach spaces which have property CWO, i.e., every finite convex combination of relatively weakly open subsets of their unit ball is open in the relative weak topology of the unit ball. Stability results of such spaces are established, and we introduce and discuss a geometric condition---property (co)---on a Banach space. Property (co) essentially says that the operation of taking convex combinations of elements of the unit ball is, in a sense, an open map. We show that if a finite dimensional Banach space $X$ has property (co), then for any scattered locally compact Hausdorff space $K$, the space $C_0(K,X)$ of continuous $X$-valued functions vanishing at infinity has…
Kokapstrādes uzņēmuma AS "INGRID D" pirmapstrādes ceha modernizācija
2018
Maģistra darba tēma ir “Kokapstrādes uzņēmuma AS “INGRID D” pirmapstrādes ceha modernizācija”. Latvijas zelts ir zaļā krāsā. Zelts ne tāpēc, ka tā ir daudz, bet gan tāpēc, ka Latvija to ir iemācījusies gudri apsaimniekot un izmantot. Pēdējo gadu laikā arvien svarīgāk ikvienam kokapstrādes uzņēmumam ir radīt produktiem augstu pievienoto vērtību, lai spētu konkurēt tirgū un efektīvi izmantot iegūtos resursus. Darba ražīgums, lietderīgais iznākums un kvalitāte ir trīs svarīgākie aspekti, kas ietekmē kokapstrādes uzņēmumu maksimāli iespējamo pievienoto vērtību radīšanu. Pētījuma mērķis ir veicināt efektīvu koksnes resursu izmantošanu to pirmapstrādes procesā. Autore pētījumu rezultātā nonākusi …
Saliency Map for Visual Perception
2015
Human and other primates move their eyes to select visual information from the scene, psycho-visual experiments (Constantinidis, 2005) suggest that attention is directed to visually salient locations in the image. This allows human beings to bring the fovea onto the relevant parts of the image, to interpret complex scenes in real time. In visual perception, an important result was the discovery of a limited set of visual properties (called pre attentive), detected in the first 200-300 milliseconds of observation of a scene, by the low-level visual system. In last decades many progresses have been made into research of visual perception by analyzing both bottom up (stimulus driven) and top d…
Bifurcations in the elementary Desboves family
2017
International audience; We give an example of a family of endomorphisms of $\mathbb{P}^2(\mathbb{C})$ whose Julia set depends continuously on the parameter and whose bifurcation locus has non-empty interior.
Common ragweed national maps & public policies in France
2014
Common ragweed (Ambrosia artemisiifolia L.) has been detected in France in the middle of the XIXth century. It has spread throughout the territory during the XXth century with a critical evolution. Public policies have not been able to contain this spread at the moment, and it is now difficult to find ways to tackle the invasion. Publication of national and regional maps seems to be an effective tool to draw up an overview of the situation and build management strategies. With a set of historical and modern data collected all over the French territory, and from many different stakeholders, we consider the progress of the species in time. The system of legislation applied locally is analyzed…
Models and tools for territorial dynamic studies (chapter 1)
2012
As part of the ArchaeDyn project, a workgroup was formed to coordinate the development, implementation and application of methods and tools for spatial analysis. The workgroup's activities were directed at various problems. The first was to construct a grid common to all the workgroups and to homogenize the study areas used by the different workgroups in their databases. The 'confidence maps' method was suggested for assessing the quality and quantity of information inventoried in the databases. Confidence maps are produced from representation and reliability maps by simple map algebra and they can be considered as 'masks' for interpreting spatial analysis results. Finally, the research tea…
Of whales and men: Caitríona O’Reilly’s septentrional voyage in “The Sea Cabinet” (2006)
2021
International audience; The title-poem of Caitríona O’Reilly’s second collection – The Sea Cabinet – is a sequence of five ekphrastic pieces paying tribute to the city of Hull’s past as a major whaling port. As she perambulates through the galleries of the Maritime Museum, the Irish poetess is inspired by all the paraphernalia on display: skeletons of various species of whales, whaler’s tools but also journals, logbooks, paintings, illustrations and hundreds of examples of the folk art and mythemes of the whaler. From one poem to the next, O’Reilly depicts the northernness of the Arctic Ocean as eery but bewitching otherness, focusing on illustrations of Captain Graville’s whaling ship ice-…
Geostatistical computing of acoustic maps in the presence of barriers
2009
Acoustic maps are the main diagnostic tools used by authorities for addressing the growing problem of urban acoustic contamination. Geostatistics models phenomena with spatial variation, but restricted to homogeneous prediction regions. The presence of barriers such as buildings introduces discontinuities in prediction areas. In this paper we investigate how to incorporate information of a geographical nature into the process of geostatistical prediction. In addition, we study the use of a Cost-Based distance to quantify the correlation between locations.
Discriminating and simulating actions with the associative self-organising map
2015
We propose a system able to represent others’ actions as well as to internally simulate their likely continuation from a partial observation. The approach presented here is the first step towards a more ambitious goal of endowing an artificial agent with the ability to recognise and predict others’ intentions. Our approach is based on the associative self-organising map, a variant of the self-organising map capable of learning to associate its activity with different inputs over time, where inputs are processed observations of others’ actions. We have evaluated our system in two different experimental scenarios obtaining promising results: the system demonstrated an ability to learn discrim…
