Resistive hystersis effects in perovskite oxide-based heterostructure junctions
M. P. Singh, L. Mechin, W. Prellier +1
In this paper, we report the electrical and structural properties of the oxide-based metal/ferroelectric/metal (MFM) junctions. The heterostructures are composed of ultrathin layer…

Fast Poisson Noise Removal by Biorthogonal Haar Domain Hypothesis Testing
Bo Zhang, Jalal Fadili, Jean Luc Starck +1
Methods based on hypothesis tests (HTs) in the Haar domain are widely used to denoise Poisson count data. Facing large datasets or real-time applications, Haar-based denoisers have…

The complexity of acyclic conjunctive queries revisited
Arnaud Durand, Etienne Grandjean
In this paper, we consider first-order logic over unary functions and study the complexity of the evaluation problem for conjunctive queries described by such kind of formulas. A n…
