Conditions for the convexity of compound geometric tails and compound geometric convolution tails are established. The results are then applied to analyze the convexity of the ruin probability and the Laplace transform of the time to ruin in the classical compound Poisson risk model with and...

Vegetation plays an important role in atmospheric, hydrologic and biochemical cycles and is an important indicator of the impact of climate and human factors on the environment. In this paper, a method, which combines the empirical orthogonal function (EOF) and temporal unmixing analysis (TUA)...

Problem definition: This article investigates the optimal combination of financing schemes (bank finance versus buyer finance) and outsourcing structures (consignment versus turnkey) in a three-tier supply chain composed of a capital-constrained quality-uncertain component supplier (SP), a...

With rising trading volumes and increasing risks in securities transactions, the securities industry is making an effort to achieve straight through processing to shorten the trade lifecycle and minimize transaction risk. While attempting to shorten the settlement cycle, the trade information...

The ESG (environmental, social, and governance) practice has become very important in contemporary business and it is believed to have a significant impact on firm value. However, there still lacks a consensus on the underlying mechanism connecting ESG and firm value. We argue that ESG can...

The power frequency high voltage divider is widely used to measure the power frequency high voltage and it is an important measuring instrument for high voltage test. Whether it is accurate or not directly affects the insulation monitoring level of power equipment closely related to the safety...

Based on the GTEM chamber for the equivalent height detection method of UHF partial discharge tester, this paper simulates the electric field at the top of the GTEM window. The results show that the electric field strength changes significantly along the position of the top fenestration axis....

Preventing systemic risk from the perspective of bank risk accumulation has been widely researched and supported. This study focuses on the impact of economic volatility on bank risk accumulation and systemic risk. Using the proportion of non-core liabilities as the bank's risk accumulation...
