The spectrum-sparse signal, which includes a fraction of large Fourier coefficients in frequency domain, is an important signal form that widely adopted in numerous fields. To handle the spectrum-sparse signal with large data sets demanded by big data applications or wideband spectrum sensing,...

Anaerobic digestion is an important approach to treat and utilize kitchen waste, while its biogas residue (BR) disposal remains a serious problem. This study investigated the feasibility of chemical looping gasification (CLG) as an efficient way to treat and generate syngas from BR. Besides,...

Using CEOs’ exposure to the Great Chinese Famine (1959-1961) as a measure of early-life trauma in their life (termed, famine-CEOs), we find that firms led by famine-CEOs are associated with lower corporate social responsibility (CSR) performance. Our findings are consistent with the egoism...
