Glycans are known as the third major class of biopolymers, next to DNA and proteins. They cover the surfaces of many cells, serving as the 'face' of cells, whereby other biomolecules and viruses interact. The structure of glycans, however, differs greatly from DNA and proteins in that they are branched, as opposed to linear sequences of amino acids or nucleotides. Therefore, the storage of glyc...
We use a model of proportionate growth to describe the dynamics of international trade flows. We provide an explanation to the fact that the extensive margin of trade account for a large fraction of the greater exports of large economies, as well as for a number of stylized facts described by the literature on trade networks such as the power-law distribution of connectivity and the fat tails d...
one of the main issues faced by the north atlantic treaty organization (nato) in the post-cold war period has been the continued existence of the organization and accommodating its goals and agenda with the new world conditions. nato in this relation has made utmost efforts within the past two decades and by making a kind of identity transformation in its functions and missions, not only did no...
this essay studies theory of lex mercatoria which is based on the assumption of existence of a third legal system along with the national and international legal systems regulating international commercial relations. for this purpose, the essay discusses the backgrounds of creation and emergence of the theory, its narrow and broad meaning, elements of which and the extent that it has been recog...
I build a simple dynamic model of the formation of an international social network of importers and exporters. Firms can only export into markets in which they have a contact. They acquire new contacts both at random, and via their network of existing contacts. This model explains (i) the cross-sectional distribution of the number of foreign markets accessed by individual exporters, (ii) the cr...
We analyze the morphological stability against azimuthal, axial, and general helical perturbations for epitaxial core-shell nanowires in the growth regimes limited by either surface diffusion or evaporation-condensation surface kinetics. For both regimes, we find that geometric parameters (i.e., core radius and shell thickness) play a central role in determining whether the nanowire remains cyl...
