Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays do not ...

Recently, numerous design schemes for high-order sparse linear arrays (SLAs) have been introduced for underdetermined direction-of-arrival (DOA) estimation based on high-order cumulants, which utilize ...

Dibromonaphthalenes are valuable building blocks in organic synthesis; however, achieving discrimination between the α- and β-bromo groups remains a challenge. In this study, we demonstrated the ...
