Design and Research on the Financial Approval Risk Control System
In the process of deepening the comprehensive risk management of financial companies, the construction of financial approval risk control is a complex and long-term system project that requires the establishment of the risk control concept and overall improvement of the risk prevention awareness in all employees. Guided by the financial approval risk control, the system construction mechanism of the company is improved to raise the operation and management level, enhance the self-improvement capacity, and provide a strong guarantee for achieving business objectives.

Natural Intelligence as the Brain of Intelligent Systems
This article discusses the concept and applications of cognitive dynamic systems (CDS), which are a type of intelligent system inspired by the brain. There are two branches of CDS, one for linear and Gaussian environments (LGEs), such as cognitive radio and cognitive radar, and another one for non-Gaussian and nonlinear environments (NGNLEs), such as cyber processing in smart systems. Both branches use the same principle, called the perception action cycle (PAC), to make decisions. The focus of this review is on the applications of CDS, including cognitive radios, cognitive radar, cognitive control, cyber security, self-driving cars, and smart grids for LGEs. For NGNLEs, the article reviews the use of CDS in smart e-healthcare applications and software-defined optical communication systems (SDOCS), such as smart fiber optic links. The results of implementing CDS in these systems are very promising, with improved accuracy, performance, and lower computational costs. For example, CDS implementation in cognitive radars achieved a range estimation error that is as good as 0.47 (m) and a velocity estimation error of 3.30 (m/s), outperforming traditional active radars. Similarly, CDS implementation in smart fiber optic links improved the quality factor by 7 dB and the maximum achievable data rate by 43% compared to those of other mitigation techniques.

Global catastrophic biological risks
This volume focuses on Global Catastrophic Biological Risks (GCBRs), a special class of infectious disease outbreaks or pandemics in which the combined capacity of the worlds private and government resources becomes severely strained. These events, of which the 1918 influenza pandemic is emblematic, cause severe disruptions in the normal functioning of the world, exact heavy tolls in terms of morbidity and mortality, and lead to major economic losses. GCBRs can be caused by any type of microorganism, and myriad contextual factors can influence their impact. Additionally, there are cascading questions that arise in connection with GCBR prediction, preparation, and response. This book gathers contributions from thought leaders who discuss the multi-faceted approaches needed in order to address this problem. From understanding the special characteristics of various microbes to financing challenges, the volume provides an essential primer on a neglected but highly relevant topic. Physicians, scientists, policymakers, public health practitioners and anyone with an interest in the field of pandemics, emerging infectious disease, biosecurity, and global health security will find it a valuable and insightful resource.

Risk-based management of invading plant disease
Effective control of plant disease remains a key challenge. Eradication attempts often involve removal of host plants within a certain radius of detection, targeting asymptomatic infection. Here we develop and test potentially more effective, epidemiologically motivated, control strategies, using a mathematical model previously fitted to the spread of citrus canker in Florida.
We test risk-based control, which preferentially removes hosts expected to cause a high number of infections in the remaining host population. Removals then depend on past patterns of pathogen spread and host removal, which might be nontransparent to affected stake-holders. This motivates a variable radius strategy, which approximates risk-based control via removal radii that vary by location, but which are fixed in advance of any epidemic.
Risk-based control outperforms variable radius control, which in turn outperforms constant radius removal. This result is robust to changes in disease spread parameters and initial patterns of susceptible host plants. However, efficiency degrades if epidemiological parameters are incorrectly characterised.
Risk-based control including additional epidemiology can be used to improve disease management, but it requires good prior knowledge for optimal performance. This focuses attention on gaining maximal information from past epidemics, on understanding model transferability between locations and on adaptive management strategies that change over time.

Credit risk
Modelling credit risk accurately is central to the practice of mathematical finance. This volume of the Mastering Mathematical Finance series offers a comprehensive and accessible introduction to the subject tailored specially for master's students. The book focuses on the two mainstream modelling approaches to credit risk, namely structural models and reduced form models, and on pricing selected credit risk derivatives. Balancing rigorous theory with real-world examples from the post-credit crisis financial markets, it takes readers through a natural development of mathematical ideas and financial intuition. Students, practitioners and researchers alike will benefit from the compact presentation and detailed worked examples, exercises and solutions.

The Application of Information Technology in Bank Accounting Internal Control Risk
The lack of the internal control conditions cause the bank accounting’s internal control risk. The cost of the internal control is large. The internal control mode is imperfect and the execution is not in place. The internal control supervision system, supervision and restraint are lack. How to perfect the internal control system and resolve the bank accounting internal control risk effectively Based on the analysis of the causes of the risk, we think that establish risk management responsibility system and strengthen the assessment of employees are the targeted suggestions.

Assessment of water environmental risks from fixed sources in the Yiluo River Basin, Luoyang, China
【Objective】Water pollution incidents pose a serious threat to public drinking water. Assessing watershed water environment risk is necessary to prevent and reduce impact of such incidents. Taking Yiluo River Basin in Luoyang City of Henan Province as an example, this paper proposes a method to assess its environmental risks.【Method】The analysis was based on analytic hierarchy process (AHP). We constructed an environmental risk assessment framework that encompasses three key factors: ① intensity of environmental risk sources, ② vulnerability of environmental receptors, and ③ capacity for environmental risk prevention, control, and emergency response. From this framework, a water environmental risk assessment was conducted for fixed-source pollution emergencies in the study region.【Result】The highest-risk areas in the basin are in proximity to the river. With the exception of certain counties in the eastern part of the basin, high-risk sectors are chemicals, petroleum, and hazardous material industries. Overall, the basin is in a medium-to-high environmental risk level. Specifically, most counties and districts in the basin are at high risk, except for parts of Luoning County in the west and Xin’an, Mengjin, and Chanhe Huiyuan District in the north, which show comparatively low risk levels.【Conclusion】The dominant environmental risk factors in the basin include the efficiency of emergency command mechanisms, availability of emergency facilities and materials, and proximity to the nearest river. Our findings provide a scientific basis for emergency preparedness and risk management of pollution incidents in the Yiluo River Basin.
