This paper employs two established macroeconomic models to show that fiscal policy in the euro area can help monetary policy in reducing inflation. Specifically, a fiscal consolidation of 1 percent of GDP for two years and 0.5 percent in the third year across the euro area would ease the policy...

Intangible investment is growing as a share of economic activity. We present a simple framework incorporating its distinguishing characteristic of generally greater scalability and lower marginal costs than tangible investment. We show evidence that this may have contributed to more elastic...

In recent years, electromagnetically induced absorption (EIA) has had potential application value in nonlinear optics and other fields, which attracts more and more attention. Based on the bright-dark-quasi-dark theory, an electromagnetically induced transparent (EIT) metamaterial is proposed...

The high temperature properties of fiber Bragg gratings (FBGs) with overexposure fabricated by femtosecond laser phase mask technology are proposed and investigated. It is found that the overexposed FBG (FBG-II) has shown higher temperature resistance of up to1000 ℃ and better high temperature...

Solar architecture system is a feasible method to reduce building energy consumption, which is great significance to realize the "Dual-carbon" plan. In this paper, the heat transfer characteristics of the photo-thermal roof are analyzed in hot summer and cold winter zone, and the calculation...
