The rise and fall of crude oil prices, gold US dollar exchange rates is great significance to investors. It necessary explore the evolution characteristics causal relationship between oil, gold, dollar, so as provide reference for We selected ICE Brent continuous futures, WTI NYMEX light COMEX index research objects. Based on theory pattern causality, divided into positive (T), negative (F), disordered (D). modal network prices against (BWCGG-U) price (U-BWCGG) were constructed. Complex...

In recent years, with the rapid development of lithium-ion battery industry, massive upstream consumption mineral raw materials has led to great crises and challenges in balancing global supply demand. A diversity trading partners can effectively alleviate pressure demand for materials; so, it is particularly important countries find suitable partners. This study takes nine minerals contained main element batteries as research object, international trade data range from 2011 2020. The...

Eosinophils, basophils, white blood cells (WBC), and immunoglobulin E (IgE) play major roles in the pathogenesis of atopic dermatitis (AD), bullous pemphigoid (BP), drug reaction with eosinophilia systemic symptoms (DRESS), hypereosinophilic syndrome (HES). This study aimed to describe these parameters different skin diseases provide further information concerning underlying pathogenesis.A cross-sectional test results, including WBC count, peripheral eosinophil basophil/WBC percentage, IgE...

The transmission of stock price fluctuations listed companies in the rare earth industry has complex characteristics. Mastering its law is great meaning to understand relationship between upstream and downstream chain market investment. This article uses time series daily closing prices stocks global past ten years as research object. Granger causality test network theory were used construct risk industrial chain. We have identified key fluctuation obtained path fluctuation. According...

Rare earth is an important strategic mineral resource, and the study of causes stock price fluctuations rare listed companies their transmission can enable all parties in market to have a clearer understanding current relationships. In this study, quantitative causality analysis model complex network method are used analyze each link within industry chain relationship between regions from among industry. The main paths also given. It found that causal stocks has positive causation, negative...

Abstract Background: The diversification of product production and consumption generates closer links between industrial sectors increases the complexity indirect energy flows interdepartmental interdependence. Methods: We calculated various in 2002, 2007, 2012 2017. Then, we have built four flow networks explored characteristics interdependence sectors. Finally, a quadratic assignment procedure correlation analysis was performed to clarify relationship dependence Results: Different play...

In recent years, with the rapid development of lithium-ion battery industry, massive consumption upstream mineral raw materials has brought great crises and challenges to balance global supply demand. This paper takes nine important minerals contained in main element batteries as research object, combines complex networks, motif link prediction methods, predicts potential trade relations based on actual network topology, summarizes three rules, finds that successfully predicted links will...
