Deconvolution of calcium imaging data using marked point processes. [PDF]

open access: yesPLoS Computational Biology, 2020
Calcium imaging has been widely used for measuring spiking activities of neurons. When using calcium imaging, we need to extract summarized information from the raw movie beforehand.

Point Processes in a Metric Space and Their Applications

open access: yesMathematics, 2022
Point processes are important in extreme value theory due to their equivalent formulations of two popular models in various applications: the block maxima models and the peak-over-threshold model.

Further results on why a point process is effective for estimating correlation between brain regions

open access: yesPapers in Physics, 2020
Signals from brain functional magnetic resonance imaging (fMRI) can be efficiently represented by a sparse spatiotemporal point process, according to a recently introduced heuristic signal processing scheme.

Rain process models and convergence to point processes [PDF]

open access: yesNonlinear Processes in Geophysics, 2023
A variety of stochastic models have been used to describe time series of precipitation or rainfall. Since many of these stochastic models are simplistic, it is desirable to develop connections between the stochastic models and the underlying physics of ...

Exponential Inequality of Marked Point Processes

open access: yesMathematics, 2023
This paper presents the uniform concentration inequality for the stochastic integral of marked point processes. We developed a new chaining method to obtain the results.

Point-shift foliation of a point process

open access: yesElectronic Journal of Probability, 2018
A point-shift $F$ maps each point of a point process $Φ$ to some point of $Φ$. For all translation invariant point-shifts $F$, the $F$-foliation of $Φ$ is a partition of the support of $Φ$ which is the discrete analogue of the stable manifold of $F$ on $Φ$.

Revealing Spectrum Features of Stochastic Neuron Spike Trains

open access: yesMathematics, 2020
Power spectra of spike trains reveal important properties of neuronal behavior. They exhibit several peaks, whose shape and position depend on applied stimuli and intrinsic biophysical properties, such as input current density and channel noise.

On the Superposition of Point Processes

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1968
Summary Given point processes N1, …, Nm their superposition is the point process N defined by N(t) = N1(t) + … + Nm(t), t ≥ 0. An equivalent description of the system (N1, …, Nm) is by the process (Xn, Tn) where the Tn are the points of N, and Xn = k if and only if Tn is a point of Nk.
