Model-free reinforcement learning with a non-linear reconstructor for closed-loop adaptive optics control with a pyramid wavefront sensor [PDF]

open access: yes, 2022
We present a model-free reinforcement learning (RL) predictive model with a supervised learning non-linear reconstructor for adaptive optics (AO) control with a pyramid wavefront sensor (P-WFS). First, we analyse the additional problems of training an RL

Engineering multiphoton states for linear optics computation [PDF]

open access: yes, 2006
Transformations achievable by linear optical components allow to generate the whole unitary group only when restricted to the one-photon subspace of a multimode Fock space.

Non-linear and non-symmetric exchange-rate adjustment: new evidence from medium and high inflation countries [PDF]

open access: yes, 2003
This paper analyses a model of non-linear exchange rate adjustment that extends the literature by allowing asymmetric responses to over- and under-valuations.

Interplay Between Sub-Cellular Alterations of Calcium Release and T-Tubular Defects in Cardiac Diseases

open access: yesFrontiers in Physiology, 2018
Asynchronous Ca2+ release promotes non-homogeneous myofilament activation, leading to mechanical dysfunction, as well as initiation of propagated calcium waves and arrhythmias.

Optimum non linear binary image restoration through linear grey-scale operations [PDF]

open access: yes, 2003
Non-linear image processing operators give excellent results in a number of image processing tasks such as restoration and object recognition. However they are frequently excluded from use in solutions because the system designer does not wish to ...

Quantitative neuroanatomy of all Purkinje cells with light sheet microscopy and high-throughput image analysis

open access: yesFrontiers in Neuroanatomy, 2015
Characterizing the cytoarchitecture of mammalian central nervous system on a brain-wide scale is becoming a compelling need in neuroscience. For example, realistic modeling of brain activity requires the definition of quantitative features of large ...

Brain-wide neuron quantification toolkit reveals strong sexual dimorphism in the evolution of fear memory

open access: yesCell Reports, 2023
Summary: Fear responses are functionally adaptive behaviors that are strengthened as memories. Indeed, detailed knowledge of the neural circuitry modulating fear memory could be the turning point for the comprehension of this emotion and its pathological
