A Biologically Inspired Representation of the Intelligence of a University Campus

2016

Abstract Intelligence or smartness in an urban environment implies several factors directed to improve quality of life and efficiency. It is important to note that in this context the inclusion of citizens and their devices is a key factor for reaching smartness. Data from mobile devices are increasingly used in everyday activities and have to be considered a useful means for handling and analyzing knowledge and communications. This paper shows how to represent important data when dealing with smartness by creating an analogy between the representation of human brain areas, activated when specific tasks are performed, and groups of students when behaviors or needs arise. The brain traffic c…

Clarifying Communication Professionals’ Tasks In Contributing To Organizational Decision Making

2017

The purpose of this paper is to discuss the tasks through which communication professionals and public relations contribute to organizational decision making. In-depth interviews were conducted with Finnish public relations professionals about how they contribute to organizational decision making. The findings provide a rich picture of the tasks in relation to this. The results show that public relations professionals contribute to organizational decision-making processes by nine different tasks. Furthermore, the results indicate that during an organizational decision-making process, professionals switch from one task to another over time, and work simultaneously on several tasks. This pape…

Hybrid Methods for Robust Irradiance Analysis and 3-D Shape Reconstruction from Images

1994

The analysis of the differential structure of images is an interesting task in machine vision, among other reasons because it can provide relevant featural representation of images, suited for higher level information processing task like geometry reconstruction and object recognition. The importance of invariants of the field of isophotae on lambertian surfaces in shape perception by means of chiaroscuro is discussed in (Koenderink and Van Doom, 1980). In their approach to shape from shading, (Breton et al, 1992) represent the shading of the image by means of its shading flow field, i.e. by the first order differential structure of the image expressed as the isoluminance direction and grad…

L’épée, arme et symbole. Le point de vue technique sur les fonctions des épées à poignée métallique de l’âge du Bronze

2018

The sword, which was invented during Bronze Age, is certainly the ultimate weapon, associated to war and warriors, designed to fight during combats. However, because of its technical complexity, its ostentatious aspect, especially when it is equipped with a bronze hilt, or its strong individualization for example through ornaments, swords can also be considered as symbols. This symbol can be connected to an individual, a social position, a community or to another concept we cannot precisely understand. Of course, material and immaterial aspects do not always exclude each other, and a single object can be used for both. However, a first inspection of these weapons shows that some of them cou…

Parliamentary Democracy Versus Direct Democracy? : Challenging Liberal, Representative Democracy in the German Bundestag During the Anti-nuclear Demo…

2019

In German politics, concepts of parliamentarism and the relationship between parliamentarism and democracy have evolved since the nineteenth century. Politicians, citizens and scholars have regularly redefined and challenged conceptions of parliament’s task of representation, public debate and legitimate decision-making in different historical circumstances. One such crucial phase in re-evaluating and redefining conceptions of democracy in Germany was the second half of the 1990s, when a vigorous anti-nuclear movement arose. In the German federal parliament, members had to explain their understandings of German democracy. The tradition of liberal, representative democracy was in a conflict …

A measure of concurrent neural firing activity based on mutual information

2020

AbstractMultiple methods have been developed in an attempt to quantify stimulus-induced neural coordination and to understand internal coordination of neuronal responses by examining the synchronization phenomena in neural discharge patterns. In this work we propose a novel approach to estimate the degree of concomitant firing between two neural units, based on a modified form of mutual information (MI) applied to a two-state representation of the firing activity. The binary profile of each single unit unfolds its discharge activity in time by decomposition into the state of neural quiescence/low activity and state of moderate firing/bursting. Then, the MI computed between the two binary st…

IL-27 improves migrational and antiviral potential of CB dendritic cells.

2013

Abstract Interleukin (IL)-27 is known to be increased considerably in cord blood (CB) dendritic cells (DCs) after TLR ligation. Previously, we demonstrated that also basal IL-27 levels are higher in CB DCs. Here, we examined effects of IL-27 on monocyte derived dendritic cells (moDCs) to approach its particular role in the specialized immune system of the human neonate. Exogenous IL-27 promotes IL-27 transcription in CB and adult blood (AB) moDCs. IL-27 acts on CB moDCs primarily by significantly augmenting IL-27 protein, secondarily by increasing transcription of CXCL10 among other chemokines, chemokine receptor CCR1, interferon stimulated genes, transcription factor IRF8 and genes involve…

MHC class II-expressing hepatocytes function as antigen-presenting cells and activate specific CD4 T lymphocyutes.

2003

The ability to activate CD4 T cells is restricted to antigen-presenting cells that express major histocompatibility complex (MHC) class II molecules. Parenchymal cells normally do not express MHC class II molecules; however, in clinical hepatitis, viral or autoimmune, hepatocytes often exhibit aberrant MHC class II expression. It is not known whether MHC class II-expressing hepatocytes can function as antigen-presenting cells, but it has been suggested that aberrant MHC class II expression by parenchymal cells may cause autoimmune disease. Therefore, we generated transgenic mice that specifically overexpress class II transactivator molecules in hepatocytes. Hepatocytes from these mice exhib…

The gp130-stimulating designer cytokine hyper-IL-6 promotes the expansion of human hematopoietic progenitor cells capable to differentiate into funct…

2000

Abstract Objective . Hyper-IL-6, a fusion protein of interleukin-6 and its specific receptor, together with stem cell factor leads to the proliferation of primitive hematopoietic progenitor cells. Based on these findings, the current study examined whether hyper-IL-6 promotes the growth of precursor cells that can be further differentiated into dendritic cells in the presence of additional cytokines. Methods . Dendritic cell cultures were generated from CD34 + hematopoietic progenitor cells derived either from bone marrow or from peripheral blood. CD34 + cells were cultured in the presence of cytokines for 2 weeks and then used for phenotyping and T-cell stimulation assays. Results . Hyper-…
