CFAR based NOMP for Line Spectral Estimation and Detection

IEEE Transactions on Aerospace and Electronic Systems, 2023
The line spectrum estimation problem is considered in this paper. We propose a CFAR-based Newtonized OMP (NOMP-CFAR) method which can maintain a desired false alarm rate without the knowledge of the noise variance. The NOMP-CFAR consists of two steps, namely, an initialization step and a detection step.

Modified reference window for two-dimensional CFAR in radar target detection

The Journal of Engineering, 2019
The constant false alarm rate (CFAR) technology plays an important role in radar target detection. In cell averaging CFAR detectors, a reference window is usually adopted to estimate the average interference power in the range–Doppler matrix and to ...

CA-CFAR Based Target Detection in FMCW Radars

2023 31st Signal Processing and Communications Applications Conference (SIU), 2023
In this study, two different FMCW radar waveforms as sawtooth and triangular are addressed. Firstly, these waveform signals are defined then the results of first Fast Fourier Transform (FFT) as range-amplitude, and second FFT of range-velocity matrix plots are obtained.

Mapping opioid exposure through prescription data and postmortem analysis of opioid drugs in multiple tissues

British Journal of Clinical Pharmacology, Volume 92, Issue 8, Page 2624-2635, August 2026.
Background and Purpose Although opioids are central to end of life (EoL) care, tissue‐level opioid exposure remains poorly understood. The objective of this study was to characterize the relationship between prescription‐derived morphine equivalent daily dose (MEDD) and measured morphine concentrations across multiple organs.

A Substance Abuse, Violence and Unhealthy Alcohol Use Syndemic Predicts Depression: A Longitudinal Study of Black Women Living With HIV in Four US Cities

Brain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Objective Black women living with HIV (BWLH) have a heightened susceptibility to depression due to factors such as intimate partner violence (IPV), alcohol use, and substance abuse. This study examined the relationship between Substance Abuse, Violence, and Heavy Alcohol use (SAVA) among BWLH to determine whether this relationship creates ...

The use of activated carbon derived from spent coffee grounds as a reusable, sustainable, and effective solution for the removal of butylparaben from water

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1547-1558, August 2026.
Abstract BACKGROUND Parabens, including butylparaben (BP), are widely used as antimicrobial preservatives in food, cosmetics, and pharmaceuticals, yet are poorly removed by conventional water treatment processes and pose potential risks to aquatic life and human health.
