The research topic related to the analysis of banking activity is relevant since the banking sector is complex and dynamic and requires constant monitoring and analysis to make informed decisions. Using a mathematical model of system dynamics to analyse banking activities can help banks make better decisions, manage risk, ensure the stability and efficiency of operations, and adapt to changing conditions. The purpose of the study is to determine the influence of various factors, in particular economic activity, on the final profit of the bank. Among the methods used, the analytical method, the functional method, the system analysis method, the deduction method, the synthesis method, and the comparison method were applied. In the course of this study, an extensive analytical review of banking activities was carried out using a system dynamics model, taking into account the requirements of the International Financial Reporting Standards(IFRS 9). The study included various scenario analyses to explore the impact of changes in economic conditions on the bank's loan portfolio,risk level, and profitability. Both economic growth scenarios and recession scenarios were considered in order to more fully assess their impact on the financial condition of the bank. A forecast and analysis of the risks associated with lending, investments, and other bank operations was carried out. The practical significance lies in the application of the results obtained to address issues related to banking in order to increase the efficiency of this process and achieve a new level of development.

A signed graph S =(Su, σ) has an underlying graph Suand a function σ : E(Su)-→{+,-}. Let E-(S) denote the set of negative edges of S. Then S is eulerian signed graph(or subeulerian signed graph, or balanced eulerian signed graph, respectively) if Suis eulerian(or subeulerian, or eulerian and |E-(S)| is even, respectively). We say that S is balanced subeulerian signed graph if there exists a balanced eulerian signed graph S′ such that S′ is spanned by *** signed line graph L(S) of a signed graph S is a signed graph with the vertices of L(S) being the edges of S, where an edge eiej is in L(S) if and only if the edges ei and ej of S have a vertex in common in S such that an edge eiej in L(S) is negative if and only if both edges ei and ej are negative in S. In this paper, two families of signed graphs S and S ′ are identified, which are applied to characterize balanced subeulerian signed graphs and balanced subeulerian signed line graphs. In particular, it is proved that a signed graph S is balanced subeulerian if and only if S?S, and that a signed line graph of signed graph S is balanced subeulerian if and only if S?S ′.

Sesame is one of the eight major allergens that cause food allergies. Study of the epitopes of sesame allergens is important for understanding their sensitization mechanisms. Currently， less information is available on the epitope studies of sesame allergens. In this study， we analyzed the molecular characteristics， structure and homology of Ses i 3， one of the important sesame allergens. We predicted the B-cell linear epitopes of Ses i 3 using bioinformatics tools and characterized them by slot blot immuno-microarrays technology. Eight peptides as B-cell linear epitopes of Ses i 3 were identified， in addition， key amino acids in these epitopes were predicted and leucine 422 was identified as a key amino acid. The present work will contribute to further understanding of the sesame allergen and provide some help in the prevention and treatment of sesame allergy.

Understanding the heterogeneous role of individuals in large-scale information spreading is essential to manage online behavior as well as its potential offline consequences. To this end, most existing studies from diverse research domains focus on the disproportionate role played by highly connected ‘hub’ ***, we demonstrate here that information superspreaders in online social media are best understood and predicted by simultaneously considering two individual-level behavioral traits: influence and susceptibility. Specifically, we derive a nonlinear network-based algorithm to quantify individuals' influence and susceptibility from multiple spreading event data. By applying the algorithm to large-scale data from Twitter and Weibo, we demonstrate that individuals' estimated influence and susceptibility scores enable predictions of future superspreaders above and beyond network centrality, and reveal new insights into the network positions of the superspreaders.
