Adaptive Hoyer-L-Moment Envelope Spectrum: A Method for Robust Demodulation of Ship-Radiated Noise in Low-SNR Environments. [PDF]

open access: yesSensors (Basel)
Propeller noise is the main source of ship-radiated noise. Extracting and analyzing the modulation characteristics from the propeller noise plays a crucial role in classifying and identifying vessel targets.

Arousal modulates functional connectivity through structured and hemispherically asymmetric community architecture during wakefulness. [PDF]

open access: yesElife
Arousal fluctuates continuously during wakefulness, yet how these moment-to-moment variations shape large-scale functional connectivity (FC) remains unclear.

EMG-Driven Musculoskeletal Modelling Framework for Virtual Simulation of Upper Limb Activation-Modulated Impairment Scenarios. [PDF]

open access: yesMedicina (Kaunas)
Background and Objectives: Surface electromyography (EMG) is widely used to assess muscle activation. However, direct interpretation of its functional biomechanical consequences remains challenging.

Muscle-tendon properties of the female athlete: a comparison between "power modulation" and "energy conservation" training exposures. [PDF]

open access: yesSci Rep
Muscle–tendon function can be categorised into “energy conservation” or “power modulation” tasks. However, little is known about how female tendons adapt to these different loading demands.

Central modulation of cardiac baroreflex moment‐to‐moment sensitivity during treadmill exercise in conscious cats

open access: yesPhysiological Reports, 2022
It remains undetermined whether the cardiac component of the entire arterial baroreflex is blunted even at the onset of low‐intensity exercise. We sought to examine the moment‐to‐moment sensitivity of the cardiac baroreflex during walking at different ...

A novel framework for extracting moment-based fingerprint features in specific emitter identification

open access: yesEURASIP Journal on Advances in Signal Processing, 2023
Extensive experiments illustrate that moments and their derivations can act as effective fingerprint features for specific emitter identification. Nevertheless, the lack of mechanistic explanation restricts the moment-based fingerprint features to a ...

Calculating the probability of error per symbol on the basis of MGF method using Rician fading for MFSK [PDF]

open access: yesTehnika, 2014
In this paper is presented how to calculate the probability of error per symbol of M-ary non-coherent frequency modulation (M-ary Frequency Shift Keying, MFSK) over a slow, flat, identically independently distributed Rician fading channels.

Novel Magnetic Field Modulation Concept Using Multiferroic Heterostructure for Magnetoresistive Sensors

open access: yesSensors, 2020
The low frequency magnetic field detection ability of magnetoresistive (MR)sensor is seriously affected by 1/f noise. At present, the method to suppress the influence of low frequency noise is mainly to modulate the measured magnetic field by mechanical ...

Zernike Moment-Based Spatial Image Steganography Resisting Scaling Attack and Statistic Detection

open access: yesIEEE Access, 2019
The mainstream adaptive steganography algorithm is difficult to resist scaling attack, and the anti-detection performance of the algorithm based on quantization index modulation is not high enough.
