Most immune responses follow Burnet's rule in that Ag recruits specific lymphocytes from a large repertoire and induces them to proliferate and differentiate into effector cells. However, the phenomenon of "original antigenic sin" stands out as a paradox to Burnet's rule of B cell engagement. Humans, upon infection with a novel influenza strain, produce Abs against older viral strains at the ex...

This paper explains why domestic debt composition in some emerging economies is risky. To this end, it carries out a systematic analysis of the determinants of the socalled domestic original sin, which refers to the inability of emerging economies to borrow domestically in local currency, at long maturities and fixed interest rates. The paper builds on a large dataset compiled by the authors fr...

This paper is concerned with a class of nonlocal dispersive models – the θ-equation proposed by H. Liu [ On discreteness of the Hopf equation, Acta Math. Appl. Sin. Engl. Ser. 24(3)(2008)423–440]: (1− ∂ x)ut + (1− θ∂ x) ( u2 2 ) x = (1− 4θ) ( ux 2 )

This article results from a process of self-assessment within Ingenieros Sin Fronteras Colombia (ISFC). The activities usually referred to as humanitarian engineering, assistive engineering, engineering for aid, and/or engineering for development are increasingly involving educational frameworks, activities, and institutions in service-learning schemes. In this article, we discuss the issues an...

Classical cognitive science was launched on the premise that the architecture of human cognition is uniform and universal across the species. This premise is biologically impossible and is being actively undermined by, for example, imaging genomics. Anthropology (including archaeology, biological anthropology, linguistics, and cultural anthropology) is, in contrast, largely concerned with the d...

In this part, we prove that the solitary wave solutions investigated in part I are extended as analytic functions in the complex plane, except at most countably many branch points and branch lines. We describe in detail how the limiting behavior of the complex sin-gularities allows the creation of non-analytic solutions with corners and/or compact support. This is the second in a series of two ...

The Quaero group is a consortium of French and German organizations working on Multimedia Indexing and Retrieval. LIG, INRIA and KIT participated to the semantic indexing task and LIG participated to the organization of this task. This paper describes these participations. For the semantic indexing task, our approach uses a six-stages processing pipelines for computing scores for the likelihood...
