Analysis of Os-Cfar and Ml-Cfar for a detection of a target in a noisy environment

open access: yes, 2023
The purpose of this work is to address the problem of detection in an inhomogeneous environment with clutter distributed in a homogeneous way for two types of detectors the OS and the ML-CFAR. The clutter is assumed to be a sea clutter represented by a Weibull distribution.

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

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
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.

Adaptive Constant False Alarm Detector Based on Composite Fuzzy Fusion Rules

open access: yesApplied Sciences
In order to improve the detection performance of the radar constant false alarm detector in a multiple-target environment, a Kaigh–Lachenbruch Quantile constant false alarm rate detector based on composite fuzzy fusion rules (CFKLQ-CFAR) is designed by ...

CD49a expression defines a metabolically robust, cytokine‐biased liver NK cell subset in rhesus macaques during lentivirus infection

open access: yesImmunology &Cell Biology, EarlyView.
Liver‐resident NK cells (CD49a+ NK cells) in rhesus macaques display distinct activating receptor and metabolic markers enhanced phenotype compared with hepatic NK cell subsets (CD49a−) in the liver. These cells exhibit heightened cytokine polyfunctionality with restrained cytotoxic responses upon mitogen stimulation in comparison with CD49a− NK cell ...

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

open access: yesJournal 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.

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

open access: yesThe 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 ...

HIV Infection and Opioid Treatment Enable the Engraftment of Kaposi Sarcoma‐Like Tumors Into Immunocompetent Mice

open access: yesJournal of Medical Virology, Volume 98, Issue 7, July 2026.
ABSTRACT The Kaposi Sarcoma herpesvirus (KSHV) causes Kaposi sarcoma (KS), primary effusion lymphoma, a lymphoproliferative disease (KSHV‐multicentric Castleman's disease), and a cytokine inflammatory syndrome (KICS). These diseases occur more frequently, though not exclusively, among people living with HIV or other types of immune dysregulation. While
