Performance of peak signal‐to‐noise ratio quality assessment in video streaming with packet losses
Electronics Letters, 2016 The effect of packet losses over error‐prone networks on visual quality of distributed video contents, estimated through subjective opinion and PSNR as an objective measure is analysed. It is shown that, within a fixed content, the variation of PSNR is a reliable indicator of the variation of packet loss rates.

Peak Detection as Multiple Testing [PDF]
, 2010 This paper considers the problem of detecting equal-shaped non-overlapping unimodal peaks in the presence of Gaussian ergodic stationary noise, where the number, location and heights of the peaks are unknown.

Noisy weak-lensing convergence peak statistics near clusters of galaxies and beyond
, 2010 Taking into account noise from intrinsic ellipticities of source galaxies, in this paper, we study the peak statistics in weak-lensing convergence maps around clusters of galaxies and beyond.

Molecular Oncology, EarlyView.Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Infrared–Visible Image Fusion via Cross-Modal Guided Dual-Branch Networks
Applied SciencesIn the field of low-altitude aerial drone data fusion, the fusion of infrared and visible light images remains challenging due to issues such as large modal differences, insufficient cross-modal alignment, and limited global context modeling. Traditional

Fuzzy Logic and Singular Value Decomposition based Through Wall Image Enhancement [PDF]
, 2012 Singular value decomposition based through wall image enhancement is proposed which is capable of discriminating target, noise and clutter signals. The overlapping boundaries of clutter, noise and target signals are separated using fuzzy logic.

Molecular Oncology, EarlyView.A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

Novel Implementation of Audio Encryption Using Pseudorandom Byte Generator
Applied Sciences, 2021 In this paper, we present an algorithm for encrypting audio files based on the Ikeda map, a mathematical function of chaos theory. Detailed experimental, security and theoretical analysis is provided on the proposed algorithm using histogram analysis ...

Bulletin of Electrical Engineering and Informatics, 2022 The problem of denoising iris pictures for iris identification systems will be discussed, as well as a novel solution based on wavelet and median filters. Different salt and pepper extraction algorithms, as well as Gaussian and speckle noises, were used.

Capacity Results on Multiple-Input Single-Output Wireless Optical Channels
, 2017 This paper derives upper and lower bounds on the capacity of the multiple-input single-output free-space optical intensity channel with signal-independent additive Gaussian noise subject to both an average-intensity and a peak-intensity constraint.
