Donsker’s Delta Functional of Stochastic Processes with Memory

open access: yesJournal of Mathematical and Fundamental Sciences, 2019
A class of stochastic processes with memory within the framework of the Hida calculus was studied. It was proved that the Donsker delta functionals of the processes are Hida distributions.

Limits of Short-Time Evolution of Local Hamiltonians [PDF]

open access: yesQuantum, 2022
Evolutions of local Hamiltonians in short times are expected to remain local and thus limited. In this paper, we validate this intuition by proving some limitations on short-time evolutions of local time-dependent Hamiltonians.

Goal Oriented Time Adaptivity Using Local Error Estimates

open access: yesAlgorithms, 2020
We consider initial value problems (IVPs) where we are interested in a quantity of interest (QoI) that is the integral in time of a functional of the solution. For these, we analyze goal oriented time adaptive methods that use only local error estimates.

Exploring new probability density functions related to Brownian local time

open access: yesKuwait Journal of Science
This work introduces a new family of probability density functions constructed from 𝐄[𝐿𝐵(1, 𝑥)], the expectation of the Brownian local time 𝐿𝐵(1, 𝑥) at time one.

Local finite-time Lyapunov exponent, local sampling and probabilistic source and destination regions [PDF]

open access: yesNonlinear Processes in Geophysics, 2015
The finite-time Lyapunov exponent (FTLE) is a powerful Lagrangian concept widely used for describing large-scale flow patterns and transport phenomena. However, field experiments usually have modest scales.

Learning Local Patterns of Time Series for Anomaly Detection

open access: yesEngineering Proceedings, 2023
The problem of anomaly detection in time series has recently received much attention, but in most practical applications, labels for normal and anomalous data are not available. Furthermore, reasons for anomalous results must often be determined. In this

Some Open Questions About the Anisotropic Random Walks

open access: yesEntropy
Between 2007 and 2018, we collaborated extensively with Pál Révész and Miklós Csörgő on many of the problems discussed in this paper. Over the past six years, we have continued to explore these issues, and here, we present some of the most intriguing ...

Predicting high-dimensional heterogeneous time series employing generalized local states

open access: yesPhysical Review Research, 2021
We generalize the concept of local states (LS) for the prediction of high-dimensional, potentially mixed chaotic systems. The construction of generalized local states (GLS) relies on defining distances between time series on the basis of their (non ...

Time tracing the earliest case of local pandemic resurgence

open access: yesFrontiers in Physics, 2023
Origin identification of the earliest cases during the pandemic is crucial in containing the transmission of the disease. The high infectiousness of the disease during its incubation period (no symptom yet) and underlying human interaction pattern make ...
