Drivers of kelp forest refugia during successive disturbance events

Journal of Ecology, Volume 113, Issue 8, Page 2013-2029, August 2025.
Cooler areas with localized upwelling acted as climate refugia during the increased ocean temperatures from the 2014–2016 marine heatwave, supporting nutrient‐rich environments and mitigating heat stress for kelp forests. However, these temperature refugia often did not spatially overlap with areas providing protection from grazing pressure, leaving ...

Vector mesons and DVCS

Nuclear Physics B - Proceedings Supplements, 2009
Recent experimental results on diffractive vector meson (VM) production and deeply virtual Compton scattering (DVCS) from the H1 and ZEUS collaborations are reviewed. The data are compared with theoretical predictions.

Hard Electroproduction of Vector Mesons [PDF]

Proceedings of the XVI International Workshop on Deep-Inelastic Scattering and Related Topics, 2008
It is reported on a global analysis of hard vector-meson electroproduction which is based on the handbag factorization. The generalized parton distributions are constructed from their forward limits with the help of double distributions and the partonic subprocesses are calculated within the modified perturbative approach.

Coherent Vector Meson Photoproduction with Nuclear Breakup in Relativistic Heavy Ion Collisions

, 2002
Relativistic heavy ions are copious sources of virtual photons. The large photon flux gives rise to a substantial photonuclear interaction probability at impact parameters where no hadronic interactions can occur.

Wildfire‐Induced Losses of Soil Particulate and Mineral‐Associated Organic Carbon Persist for Over 4 Years in a Chaparral Ecosystem

Global Change Biology, Volume 31, Issue 8, August 2025.
Wildfires can lower soil carbon (C) stocks directly through combustion, but also indirectly during post‐fire recovery if microbial respiration outpaces photosynthetic C inputs. To assess controls over post‐fire soil C stocks, we measured particulate organic carbon (POC), mineral‐associated organic carbon (MAOC), and microbial and plant communities for ...

X(3872): propagating in a dense medium

Nuclear Physics B, 2018
In cold nuclear matter, the shifts in the mass and current-meson coupling as well the vector self energy of the exotic X(3872) are calculated using the diquark–antidiquark current within the framework of the in-medium two-point QCD sum rule.

Vector meson production in coherent hadronic interactions: Update on predictions for energies available at the BNL Relativistic Heavy Ion Collider and the CERN Large Hadron Collider [PDF]

, 2011
In this Rapid Communication we update our predictions for the photoproduction of vector mesons in coherent $\mathit{pp}$ and $\mathit{AA}$ collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies using the color ...

Limited tree mortality in unburned areas linked to bark beetle spillover from wildfires

Ecological Applications, Volume 35, Issue 5, July 2025.
Abstract Increased fire activity in the western United States since 2000 has produced an abundance of fire‐injured trees at risk to lethal attack by bark beetles. Large populations of bark beetles reproducing in fire‐injured trees may disperse (or spillover) from inside the fire perimeter to adjacent, unburned forests, potentially causing extensive ...

Impact of vector meson polarization on its interaction with matter

European Physical Journal C: Particles and Fields
The production of unstable particles on different nuclei provides the possibility to determine the total cross section of the interaction of vector mesons $$V=\rho ,\omega ,\varphi , K^{*0}(892),J/\psi $$ V = ρ , ω , φ , K ∗ 0 ( 892 ) , J / ψ etc.

Intraspecific Functional Trait Variation and Coordination in Schizachyrium scoparium

Ecology and Evolution, Volume 15, Issue 7, July 2025.
Understanding how traits vary within and between populations of plant species and how axes of trait variation describe trade‐offs in plant function is necessary to fully realize the utility of functional traits in ecological restoration. We investigated intraspecific trait variation among five populations of Schizachyrium scoparium (little bluestem), a
