Photonic Energy‐Coherence Theorem and Experimental Validations

Laser &Photonics Reviews, EarlyView.
A thermodynamic framework for quantum wave‐particle duality is presented, where each behaviors attribute is quantified through the extractable energy of a system. The energy capacity establishes a direct connection to both fringe visibility and path distinguishability. Active control of single‐photon states demonstrates distinct energetic contributions

USE OF TRIANGULAR MODELS OF NON-STATIONARY PROCESSES IN MODELING VARIABILITY OF HEART RHYTHM

Сучасний стан наукових досліджень та технологій в промисловості, 2019
The subject matter is a mathematical model describing the process of heart rhythm variability, which is based on the use of triangular models of non-stationary random processes in the Hilbert space.

Simultaneous Photoacoustic and Laser‐Induced Ultrasound Imaging of Animals and Humans via a Semi‐Transparent Ultrasound Transducer

Laser &Photonics Reviews, EarlyView.
Combined photoacoustic (PA) and ultrasound (US) imaging commonly requires an external pulser to transmit US waves, making systems relatively complicated and suboptimal. Here simultaneous PA and laser‐induced US imaging is demonstrated without using a US pulser. A semi‐transparent ultrasound transducer converts some portion of excitation laser energy to

Scaling Properties of Atmospheric Wind Speed in Mesoscale Range

Atmosphere, 2019
The scaling properties of turbulent flows are well established in the inertial sub-range. However, those of the synoptic-scale motions are less known, also because of the difficult analysis of data presenting nonstationary and periodic features ...

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states

Mathematische Nachrichten, EarlyView.
Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

Feature Extraction of Weak Fault for Rolling Bearing based on Improved SSD Denoising

Jixie chuandong, 2022
Aiming at the problem of early weak fault features of rolling bearings are difficult to be extracted under strong background noise and the components decomposed by the singular spectral decomposition method still contain noise，a method of extracting the ...

Exponential Stability of Higher Order Fractional Neutral Stochastic Differential Equation Via Integral Contractors

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6425-6446, April 2025.
ABSTRACT The well‐posedness results for mild solutions to the fractional neutral stochastic differential system with Rosenblatt process with Hurst index Ĥ∈12,1$$ \hat{H}\in \left(\frac{1}{2},1\right) $$ is discussed in this article. To demonstrate the results, the concept of bounded integral contractors is combined with the stochastic result and ...

Attractors for an Energy‐Damped Viscoelastic Plate Equation

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a class of non‐autonomous beam/plate equations with an integro‐differential damping given by a possibly degenerate memory and an energy damping given by a nonlocal ε$$ \varepsilon $$‐perturbed coefficient. For each ε>0$$ \varepsilon >0 $$, we show that the dynamical system generated by the weak solutions of the ...

Applications of Fast Iterative Filtering in NMR Spectroscopy: Baseline Correction

Magnetic Resonance in Chemistry, EarlyView.
Fast iterative filtering is a signal decomposition technique related to empirical mode decomposition. When decomposing NMR data into intrinsic mode functions, FIF effectively partitions broad baseline components from narrow peaks components, even in heavily distorted spectra, for instance, those of paramagnetic compounds.
