Grain refinement and eutectic Si modification of hypoeutectic Al-Si alloys are crucial to improving their mechanical properties. In this paper, the effects of a novel Al-3Ti-4.35La master alloy on the morphology of eutectic Si in and mechanical properties of hypoeutectic Al-7Si alloy were...

This paper proposes a supplementary regulatory indicator “LA” by introducing the Net Stable Funding Ratio (NSFR) into DLM model, and investigates the heterogenous impacts of liquidity management behavior on the transmission of monetary policy in the two types of commercial banks classified...

Double valence states europium modified [110]-confined Li 4 Ti 5 O 12 nanocluster is successfully prepared by method of co-precipitation. The Li 4 Ti 5 O 12 nanocluster shows high initial discharge capacity (183.5 mAh g -1 at 5 C) and excellent rate performance (145.9 mAh g -1 at 100 C ). Double...

Accurate prediction of the remaining useful life (<i>RUL</i>) of lithium-ion batteries is important for battery management systems. Traditional empirical data-driven approaches for <i>RUL</i> prediction usually require multidimensional physical characteristics including the current, voltage, usage duration,...

In recent years, life insurers have increased their exposure to socially controversial bonds from alcohol, tobacco, and gaming sectors, which contradicts social-norm constraints of such institutional investors. We show empirically that the practice of investment delegation contributes to the...

Whether the real performance of corporate social responsibility is related to social progress and development in the critical period of China's economic transformation. It is crucially significant for improving social welfare and promoting high-quality economic development to clarify the...

Two new two-dimensional (2D) materials known as covalent organic framework (COF) and graphene phase carbon nitride nanosheets (CNNS) have induced great interests in photocatalysis due to their highly π-conjugate structure and wide light absorption. Herein, metal-free COF-CNNS hybrids were...

As people's protection awareness about electromagnetic pollution is gradually increasing, the demand for absorbing materials with renewability and environmental friendliness has attracted widespread attention. In this paper, the straw-derived biochar combined with NiCo alloys were successfully...

Value at risk (VaR) and expected shortfall (ES) have emerged as standard measures for detecting the market risk of financial assets and play essential roles in investment decisions, external regulations, and risk capital allocation. However, existing VaR estimation approaches fail to accurately...

Corporate mergers and acquisitions (M&As) are subject to skewed logic due to excessive government regulation. China is progressively adopting the Market Access Negative List (MANL) pilot to transfer the power of resource allocation from the government to the market. Using the DID method, we...
