Practical geopolitics in cinematic narratives of Marvel’s The Avengers film franchise

This article implies that cinematic narratives project practical geopolitical discourses by using the example of Marvel Cinematic Universe’s success – The Avengers film franchise. The conceptualisation of imaginary threats in the films that follow the main storyline of the Avengers assembly, determined by the time and the geographic space, give those threats a  symbolical manifestation that tends to overlap with the practical geopolitical notions of American foreign policy, as well as contemporary international politics. The interpretative textual analysis of the films’ narratives and their relations to world politics, hence, presents the central methodology of this article. The relation between those two has a capacity to transmit a subconscious message to blockbusters’ consumers about preferable practical geopolitical visions in contemporary world politics. Simply, the paper shows how cinematic narratives form an identity that is deeply securitised and able to capture the Zeitgeist of world’s politics.info:eu-repo/semantics/publishedVersio

Migration and Final Location of Hot Super Earths in the Presence of Gas Giants

Based on the conventional sequential-accretion paradigm, we have proposed that, during the migration of first-born gas giants outside the orbits of planetary embryos, super Earth planets will form inside the 2:1 resonance location by sweeping of mean motion resonances (Zhou et al. 2005). In this paper, we study the subsequent evolution of a super Earth (m_1) under the effects of tidal dissipation and perturbation from a first-born gas giant (m_2) in an outside orbit. Secular perturbation and mean motion resonances (especially 2:1 and 5:2 resonances) between m_1 and m_2 excite the eccentricity of m_1, which causes the migration of m_1 and results in a hot super Earth. The calculated final location of the hot super Earth is independent of the tidal energy dissipation factor Q'. The study of migration history of a Hot Super Earth is useful to reveal its Q' value and to predict its final location in the presence of one or more hot gas giants. When this investigation is applied to the GJ876 system, it correctly reproduces the observed location of GJ876d around 0.02AU.Comment: 7 pages, 4 figure

Optimisation of the structure of the dealing service of the bank with a limited base of counteragents Оптимизация структуры дилинговой службы банка с ограниченной базой контрагентов

The article considers methods of assessment of optimal parameters of the dealing service of the bank with a limited base of counteragents. The methods are based on a mathematical model of microstructure of the interbank currency market [5]. The methods allow identification of optimal parameters of the infrastructure of the dealing service of the bank based on indicators of dynamics of currency rates and market environment of the bank.В статье рассматривается методика оценки оптимальных параметров дилинговой службы банка с ограниченной базой контрагентов. Методика основана на математической модели микроструктуры межбанковского валютного рынка [5]. Методика позволяет определить оптимальные параметры инфраструктуры дилинговой службы банка, исходя из показателей динамики валютных курсов и рыночного окружения банка

Coarse-Grained Modeling of Genetic Circuits as a Function of the Inherent Time Scales

From a coarse-grained perspective the motif of a self-activating species, activating a second species which acts as its own repressor, is widely found in biological systems, in particular in genetic systems with inherent oscillatory behavior. Here we consider a specific realization of this motif as a genetic circuit, in which genes are described as directly producing proteins, leaving out the intermediate step of mRNA production. We focus on the effect that inherent time scales on the underlying fine-grained scale can have on the bifurcation patterns on a coarser scale in time. Time scales are set by the binding and unbinding rates of the transcription factors to the promoter regions of the genes. Depending on the ratio of these rates to the decay times of the proteins, the appropriate averaging procedure for obtaining a coarse-grained description changes and leads to sets of deterministic equations, which differ in their bifurcation structure. In particular the desired intermediate range of regular limit cycles fades away when the binding rates of genes are of the same order or less than the decay time of at least one of the proteins. Our analysis illustrates that the common topology of the widely found motif alone does not necessarily imply universal features in the dynamics.Comment: 29 pages, 16 figure

A Sol-Gel Process for the Preparation of Micro-Spheroids of Nickel (II) Hydroxide

The sol-gel procedure for the preparation of nickel(!!) hydroxide micro-spheroids of definite size and shape is described. The process is a two-stage operation. In the first stage the concentrated sol of Ni(OHh is produced by a sequence of precipitation, centrifugation, resuspension and electrodialysis. In the second stage the sol is transformed into a gel in a column in the counter-current flow of a dehydrating alcohol. Flow rate control of the sol and of the dehydrating agent allow preparation of spherical particles of different diameters in the range of 0.1 to 0.3 mm
