The statistics of wide-separation lensed quasars [PDF]
, 2000 The absence of any wide-separation gravitational lenses in the Large Bright Quasar Survey is used to place limits on the population of cluster-sized halos in the universe, and hence constrain a number of cosmological parameters.

Line-Of-Sight Interference Statistics and User Scheduling with 3D Angular Separation [PDF]
International Journal of Antennas and Propagation, 2018 We focus on the interference statistical metrics of matched filter transmission over line-of-sight (LoS) downlink channels. The exact moments of the interference are derived, which can be used to make approximations for user rates and gain insights into ...

Advanced intermittent clutter filtering for radar wind profiler: signal separation through a Gabor frame expansion and its statistics [PDF]
Annales Geophysicae, 2008 A new signal processing method is presented for the suppression of intermittent clutter echoes in radar wind profilers. This clutter type is a significant problem during the seasonal bird migration and often results in large discrepancies between ...

Statistics of the separation between sliding rigid rough surfaces: Simulations and extreme value theory approach [PDF]
, 2019 When a rigid rough solid slides on a rigid rough surface, it experiences a random motion in the direction normal to the average contact plane. Here, through simulations of the separation at single-point contact between self-affine topographies, we ...

Signal separation using second and high order statistics [PDF]
Proceedings of the Sixteenth National Radio Science Conference. NRSC'99 (IEEE Cat. No.99EX249), 2000 Summary: This paper presents two methods for signal separation. In either method, the fundamental criterion for separation relies on reducing to zero, or at least minimizing, the output cross-correlation or cross-cumulant functions of a decoupling multi-input-multi-output system that is fed with mixed signals.

A Separation Algorithm for Sources with Temporal Structure Only Using Second-order Statistics
Radioengineering, 2013 Unlike conventional blind source separation (BSS) deals with independent identically distributed (i.i.d.) sources, this paper addresses the separation from mixtures of sources with temporal structure, such as linear autocorrelations.

A statistics-based automated flood event separation
Journal of Hydrology X, 2021 The classification of characteristics of flood events, like peak, volume, duration and baseflow components is essential for many hydrological applications such as multivariate flood statistics, the validation of rainfall-runoff models and comparative ...

Identification of tagged glycans with a protein nanopore
Nature Communications, 2023 The structural complexity of glycans seriously challenges the currently available analytical methods. Here, the authors report the identification of glycan isomers, glycans with varying chain lengths, and distinct branched glycans, via a glycan ...
