Concurrent Use of Extra‐Medical Medication for Opioid Use Disorder Among Adults Prescribed Methadone or Buprenorphine: A Cohort Study of Urban Adults Who Have Injected Drugs

open access: yesDrug and Alcohol Review, Volume 45, Issue 5, July 2026.
ABSTRACT Introduction In a policy environment with constrained access to the medications for opioid use disorder (MOUD), we examined the prevalence and correlates of extra‐medical use of these medications among individuals already prescribed MOUD.

Prevalence of Avoidant/Restrictive Food Intake Disorder (ARFID) in children with and without food allergy

open access: yesPediatric Allergy and Immunology, Volume 37, Issue 7, July 2026.
Abstract Introduction Emerging research suggests those with food allergy may have a higher risk of eating and feeding disorders; however, data on the prevalence of Avoidant/Restrictive Food Intake Disorder (ARFID) among individuals with food allergy is limited.

From Phosphinimines to Four‐Membered SiCPN Cations: Insights Into N–Si Bonding and Ring Strain

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 18, 22 June 2026.
Sterically tuned N‐silyl phosphinimines enable four‐membered SiCPN cations. Hydride abstraction yields cyclic cations for Me and iPr substituents at silicon, while tBu gives a protonated intermediate. Multinuclear NMR spectroscopy, X‐ray crystallography, thermochemical density functional theory investigations, and natural bond orbital analyses reveal ...

Knowledge-aided Bayesian covariance matrix estimation in compound-Gaussian clutter [PDF]

open access: yes, 2010
We address the problem of estimating a covariance matrix R using K samples zk whose covariance matrices are kR, where k are random variables. This problem naturally arises in radar applications in the case of compound-Gaussian clutter. In contrast to the

REVIEW OF RADAR DETECTORS WITH CONSTANT FALSE ALARM RATE

open access: yesTelemática, 2020
Radar detection in environments with high spatial and temporal variability is an issue of great importance. Many efforts are devoted to the development of adaptive techniques that allow robust operation for all possible scenarios.

Constant false alarm rate detection method in polarimetric synthetic aperture radar imagery based on whitening filter under inverse beta distribution

open access: yesThe Journal of Engineering, 2019
The constant false alarm rate (CFAR) detection method based on multi-look polarisation whitening filter (MPWF) has not been obtained in the polarimetric synthetic aperture radar imagery when the texture variable obeys the Inverse Beta distribution.

A bayesian approach to adaptive detection in nonhomogeneous environments [PDF]

open access: yes, 2008
We consider the adaptive detection of a signal of interest embedded in colored noise, when the environment is nonhomogeneous, i.e., when the training samples used for adaptation do not share the same covariance matrix as the vector under test. A Bayesian

Robust CFAR Detector Based on Truncated Statistics for Polarimetric Synthetic Aperture Radar [PDF]

open access: yes, 2020
Constant false alarm rate (CFAR) algorithms using a local training window are widely used for ship detection with synthetic aperture radar (SAR) imagery. However, when the density of the targets is high, such as in busy shipping lines and crowded harbors,

Cryo‐EM structure of ALC1 in an open conformation bound to a PARylated nucleosome

open access: yesActa Crystallographica Section D, Volume 82, Issue 6, Page 683-699, June 2026.
Reanalysis of a publicly available cryo‐EM dataset identifies a new conformation of the oncogenic chromatin remodeler ALC1/CHD1L bound to a PARylated nucleosome. This new structure reveals the position of the macro domain in the complex, and may help to understand the large conformational change leading to the activation of ALC1.Nucleosomes are the ...
