Article Synopsis
- Measuring deeply virtual Compton scattering (DVCS) on the neutron is essential for understanding the nucleon's structure through generalized parton distributions (GPDs).
- Neutron targets help complement data obtained from polarized protons, particularly in determining the poorly understood GPD E, which is crucial for analyzing quark contributions to nucleon spin.
- The experiment utilized a longitudinally polarized electron beam at Jefferson Lab and the CLAS12 detector to measure DVCS on the neutron for the first time, providing new insights into quark-flavor separation of relevant Compton form factors.
Shortly after the establishment of African swine fever virus (ASFV) genotype II in 2007, cases of acute fatal infection were observed. However, after several years of circulation in the Eurasian region, the clinical signs of the disease changed. Currently, this disease can occur acutely, subclinically, chronically, or asymptomatically.

- The study investigated viral diseases affecting honey bees in Armenia, focusing on the presence of these viruses in bees, non-bee species, mites, and pollinated plants.
- A total of 200 bees, 50 mites, and 20 wasps were sampled, revealing the presence of six honey bee viruses, with the most common being deformed wing virus (DWV), acute bee paralysis virus (ABPV), and acute bee norovirus (ANV).
- Findings suggest that while honey bees carry these viruses, they were also found in wasps and that plants may serve as reservoirs, contributing to the seasonal spread of these viruses.
The polarized cross-section ratio σ_{LT^{'}}/σ_{0} from hard exclusive π^{-}Δ^{++} electroproduction off an unpolarized hydrogen target has been extracted based on beam-spin asymmetry measurements using a 10.2 GeV/10.6 GeV incident electron beam and the CLAS12 spectrometer at Jefferson Lab.
