This paper explores the relationship between public policy and entrepreneurial activity in EU countries by using the panel threshold model.The paper was fundamental based on j&d manufacturing website and confirmed the psychological threshold theory; namely, the results showed a single threshold effect between government effectiveness and entreprene
This study presents a multi-band conformal antenna based endoscopic system for robust biotelemetry communications, which covers five important bands, including the MedRadio (401-406 MHz), Industrial, Scientific, and Medical (ISM) (433.1-434.8 MHz, 868-868.6 MHz, 902-928 MHz), and midfield (1200 MHz) bands.These bands are intended for functions such
In the cascaded H-bridge inverter (CHBI) with supercapacitor and dc-dc stage, inherent second-order harmonic power flows through each submodule (SM), causing fluctuations in both the dc-link voltage and the dc-dc current.There exist limitations in handling these fluctuations at variable output frequencies when employing proportional-integral (PI) c
The Qaidam Basin is a large transpressional Mesozoic to Cenozoic basin in the Tibet Plateau, West China.Since the Indosinian Movement, it has been in the subsidence stage and more than 3 trillion cubic meters of natural gas accumulated at the same time.The palaeoclimate evolution during the Pliocene Shizigou stage not only controlled sequence strat
