DOI: 10.1007/s00041-020-09744-8
Abstract: We study a concentration problem on the unit sphere $$\mathbb {S}^2$$ S 2 for band-limited spherical harmonics expansions using large sieve methods. We derive upper bounds for concentration in terms of the maximum Nyquist density.… read more here.

DOI: 10.1109/tgrs.2022.3229685
Abstract: Time-delay estimation is a critical step in many geophysical applications. Conventional approaches are mainly based on the cross correlation of waveforms in time domain but show strong distortions with multiple oscillations and side lobes. We… read more here.

Abstract: The quantum theory of optical coherence plays a ubiquitous role in identifying optical emitters. An unequivocal identification, however, presumes that the photon number statistics is resolved from timing uncertainties. We demonstrate from first principle that… read more here.
