A new commutativity property of exceptional orthogonal polynomials
(Springer, 2024-03-29)
We exhibit three examples showing that the “time-and-band limiting” commutative property found and exploited by D. Slepian, H. Landau and H. Pollak at Bell Labs in the 1960s, and independently by M. Mehta and later by C. ...

Widespread latitudinal asymmetry in the performance of marginal populations: A meta-analysis
(Wiley-Blackwell, 2023-06)
Aim: Range shifts are expected to occur when populations at one range margin perform better than those at the other margin, yet no global trend in population performances at range margins has been demonstrated empirically ...
