Molecular Ecology, Volume 35, Issue 9, May 2026.ABSTRACT Understanding how aerial fungal diversity varies across space, habitat, and disturbance is key to linking local‐scale sporocarp (fruiting body) reproduction with continental‐scale biogeography. In this study, we combined passive spore trap metabarcoding with macrofungal sporocarp records from 31 plots in eight sites across North America to ...

Galaxies, 2016 Since the mid-1980s, the shock-in-jet model has been the preferred paradigm to explain radio-band flaring in blazar jets. We describe our radiative transfer model incorporating relativistically-propagating shocks, and illustrate how the 4.8, 8, and 14.5 ...

Identifying the 3FHL Catalog. VI. Results of the 2019 Gemini Optical Spectroscopy
The Astronomical Journal, 2023 Active galactic nuclei with their relativistic jets pointed toward the observer are a class of luminous gamma-ray sources commonly known as blazars. The study of this source class is essential to unveil the physical processes powering these extreme jets,

, 2012 The Universe is opaque to extragalactic very high-energy gamma rays (VHEGRs, E>100 GeV) because they annihilate and pair produce on the extragalactic background light.

Blazars in the Fermi Era: The OVRO 40-m Telescope Monitoring Program [PDF]
, 2010 The Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope provides an unprecedented opportunity to study gamma-ray blazars. To capitalize on this opportunity, beginning in late 2007, about a year before the start of LAT science operations,

Collagen organisation in the fibrous joint capsules in the digits of the human hand
Journal of Anatomy, Volume 248, Issue 4, Page 612-623, April 2026.The function of the finger joints is important for daily life. In this review of the literature, we consider the role of collagen and its organization within the fibrous finger joint capsules of the interphalangeal (IP) joints and investigate the relationships between collagen orientation and joint function. Abstract Normal function of the hand and, in

Galaxies, 2016 This paper discusses the spectral energy distribution (SED) of all blazars with redshift detected by the Fermi satellite and listed in the 3LAC catalog. The so called “blazar sequence” from the phenomenological point of view will be updated, with no theory or modelling. It will be shown that: (i) pure data show that jet and accretion power are related;

Journal of Policy Analysis and Management, Volume 45, Issue 2, Spring 2026.ABSTRACT Recruiting teachers via “grow‐your‐own” (GYO) programs is a popular, yet rarely evaluated, strategy for addressing local workforce shortages and ensuring that incoming teachers resemble, understand, and have strong connections to their communities.

XMM-Newton View of PKS 2155-304: Characterizing the X-ray Variability Properties with EPIC-PN [PDF]
, 2005 Starting from XMM-Newton EPIC-PN data, we present the X-ray variability characteristics of PKS 2155-304 using a simple analysis of the excess variance, \xs, and of the fractional rms variability amplitude, fvar.
