Abstract: Several sparse linear array structures have recently been proposed to enhance the identifiability of direction-of-arrival estimation by using second-order or higher even-order statistics ...

I have a data frame for which one column is a nested struct array. Converting it to a pyarrow.Table fails if the data frame gets too big. I could reproduce the bug with a minimal example with ...

ABSTRACT: An asymptotic existence of balanced incomplete block (BIB) designs and pairwise balanced designs (PBD) has been discussed in [1]-[3]. On the other hand, the existence of additive BIB designs ...

Im guessing this is built into the language, but I can't seem to find anything on it, and I'm just trying to get it done, so here I am to ask. Have a nested array that my function is returning, and I ...
