Under the background of 'Carbon Neutral' commitments by various governments, the services agglomeration may play an important role in service sector energy efficiency. This paper explores the mechanisms behind the effects of services agglomeration on service sector energy efficiency. We employ...

Based on the Sapir-Whorf hypothesis (Whorf 1956), we predict that grammatically referencing the future, which...

We have demonstrated a flat multi-wavelength Brillouin erbium-doped fiber laser (MWBEFL) based on a Sagnac loop with an unpumped erbium-doped fiber (Un-EDF). A Sagnac loop with an Un-EDF is used as power equalizer to achieve multi-wavelength power flatness by adjusting the birefringence beat...
