Derivation of a health‐based guidance value for Δ8‐tetrahydrocannabinol (Δ8‐THC) and its occurrence in food

open access: yesEFSA Journal, Volume 23, Issue 11, November 2025.
Abstract The European Food Safety Authority (EFSA) was asked to deliver a scientific opinion on the derivation of a health‐based guidance value (HBGV) for Δ8‐tetrahydrocannabinol (Δ8‐THC) in food with an assessment of the occurrence of Δ8‐THC and the co‐occurrence with Δ9‐THC in hemp and hemp‐derived products.

Probing the Distinct Extinction Law of the Pillars of Creation in M16 with JWST

open access: yesThe Astrophysical Journal Letters
Investigating the extinction law in regions of high dust extinction, such as the Pillars of Creation within the M16 region, is crucial for understanding the densest parts of the interstellar medium (ISM).

Reddening the nighttime environment: Use of PC‐amber LED lighting

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
The use of Phosphor‐converted amber (PC‐amber) LED lamps has been widely championed as a means of reducing the environmental impacts of the use of artificial light at night. Here we argue that evidence for the efficacy of PC‐amber LEDs in such reductions is presently limited and that these lamps should not be seen as a panacea for the environmental ...

Assessing the Effects of Composition and Surface Roughness on the Photopolarimetric Response of Planetary Regoliths

open access: yesThe Astrophysical Journal Supplement Series
This study is part of an ongoing project in which we experimentally examine the effect of composition (refractive index) and surface roughness on the scattering matrix elements of a set of well-characterized rough regolith simulants.

The Reddening law outside the local group galaxies: The case of NGC 7552 and NGC 5236

open access: yesThe Astrophysical Journal, 1994
The dust reddening law from the UV to the near-IR for the extended regions of galaxies is here derived from the spectral distributions of the starburst spiral galaxies NGC 7552 and NGC 5236. The centers of these galaxies have similar absorption and emission line spectra, differing only if the strength of their interstellar lines and in the continuum ...

The SDSS Galaxy Angular Two-Point Correlation Function [PDF]

open access: yes, 2013
We present the galaxy two-point angular correlation function for galaxies selected from the seventh data release of the Sloan Digital Sky Survey. The galaxy sample was selected with $r$-band apparent magnitudes between 17 and 21; and we measure the ...

AAPM WGTEACH Report 366: Best practices in the teaching and mentoring of medical physics

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.
Abstract Working Group on Teaching Educators and Clinicians How (WGTEACH) has been charged with writing a report to review best, evidence‐based practices in various aspects of the teaching of medical physics. These aspects include not only didactic teaching and mentoring in the classroom and clinic, but also teaching K‐12 and undergraduate students and

Exploring the Wolf Approach to Constraining NIR Extinction Laws in the Corona Australis Molecular Cloud

open access: yesThe Astronomical Journal
The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

Revisiting the role of the Thermally-Pulsating Asymptotic Giant Branch phase in high-redshift galaxies [PDF]

open access: yes, 2015
We study the debated contribution from thermally pulsing asymptotic giant branch (TP-AGB) stars in evolutionary population synthesis models. We investigate the Spectral Energy Distributions (SEDs) of a sample of 51 spectroscopically confirmed, high-z ($1.

An Examination of Tuition Revenue Dependence as a Predictor of Master's Programme and Degree Completion Growth in the United States

open access: yesHigher Education Quarterly, Volume 79, Issue 4, October 2025.
ABSTRACT Since the 1970s, master's degrees represent the fastest growing degree in the United States (US). Accordingly, there is a need for greater understanding of the factors that have contributed to this sustained, upward trend. Guided by resource dependence theory, we conducted hierarchical multiple linear regression analyses to examine whether ...
