Orthogonalization of Positive Operator Valued Measures
Comptes Rendus. Mathématique, 2022 We show that a partition of the unity (or POVM) on a Hilbert space that is almost orthogonal is close to an orthogonal POVM in the same von Neumann algebra. This generalizes to infinite dimension previous results in matrix algebras by Kempe–Vidick and Ji–

Embedded Mean-Field Theory with Block-Orthogonalized Partitioning [PDF]
Journal of Chemical Theory and Computation, 2017 Embedded mean-field theory (EMFT) provides a simple, flexible framework for describing subsystems at different levels of mean-field theory. Subsystems are defined by partitioning a one-particle basis set, with a natural choice being the atomic orbital (AO) basis. Although generally well behaved, EMFT with AO partitioning can exhibit unphysical collapse

Lattice Partition Multiple Access: A New Method of Downlink Non-Orthogonal Multiuser Transmissions [PDF]
Global Communications Conference, 2016 In this paper, we propose a new downlink non-orthogonal multiuser superposition transmission scheme for future 5G cellular networks, which we refer to as the lattice partition multiple access (LPMA).

Opposing trends of cloud coverage over land and ocean under global warming [PDF]
Atmospheric Chemistry and Physics, 2023 Clouds play a key role in Earth's energy budget and water cycle. Their response to global warming contributes the largest uncertainty to climate prediction.

SYK Model with global symmetries in the double scaling limit
Journal of High Energy Physics, 2023 We discuss the double scaling limit of the SYK model with global symmetries. We develop the chord diagram techniques to compute the moments of the Hamiltonian and the two point function in the presence of arbitrary chemical potential.

Improved Local Ternary Patterns for Automatic Target Recognition in Infrared Imagery
Sensors, 2015 This paper presents an improved local ternary pattern (LTP) for automatic target recognition (ATR) in infrared imagery. Firstly, a robust LTP (RLTP) scheme is proposed to overcome the limitation of the original LTP for achieving the invariance with ...
