Dark Matter detection via lepton cosmic rays [PDF]

, 2010
Recent observations of lepton cosmic rays, coming from the PAMELA and FERMI experiments, have pushed our understanding of the interstellar medium and cosmic rays sources to unprecedented levels.

Gamma Rays from Cosmic Rays in Supernova Remnants [PDF]

, 2013
Context: Cosmic rays are thought to be accelerated at supernova remnant (SNR) shocks, but conclusive evidence is lacking. Aims: New data from ground-based gamma-ray telescopes and the Large Area Telescope on the Fermi Gamma-ray Space Telescope are used ...

The formation of heterogeneous storeys in the cambium on the example of Laburnum anagyroides Medik

Acta Agrobotanica, 2012
The formation of the storeyed pattern of cambium in the first two years of cambial activity and the structure of mature cambium was examined in Laburnum anagyroides, a decorative shrub growing in temperate climate.

Texture-based brain networks for characterization of healthy subjects from MRI

Scientific Reports, 2023
Brain networks have been widely used to study the relationships between brain regions based on their dynamics using, e.g. fMRI or EEG, and to characterize their real physical connections using DTI.

Active Galactic Nuclei with Starbursts: Sources for Ultra High Energy Cosmic Rays [PDF]

, 2009
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst in the radio galaxy Cen A pushed up in energy by the shock of a relativistic jet.

Social network-based group intervention to promote uptake of cervical cancer screening in Uganda: study protocol for a pilot randomized controlled trial

Pilot and Feasibility Studies, 2022
Introduction Cervical cancer (CC) is the most common cancer and accounts for one quarter of all cancer-related deaths among women in Uganda, where lifetime CC screening is estimated to be as low as 5%.

Assessment of the impact of gillnets on the population structure of the shovelnose guitarfish Rhinobatos productus from the Gulf of California, Mexico

Ciencias Marinas, 2011
The shovelnose guitarfish Rhinobatos productus is the most abundant species in the artisanal ray fishery of the Gulf of California. This ray is captured when it approaches the coast for reproductive purposes and is highly vulnerable to gillnets used in ...

Mediators and moderators of the effect of the game changers for cervical cancer prevention intervention on cervical cancer screening among previously unscreened social network members in Uganda

BMC Cancer, 2023
Introduction Cervical cancer (CC) rates are high in Uganda, yet CC screening rates are very low. Our peer advocacy group intervention, Game Changers for Cervical Cancer Prevention (GC-CCP), was shown to increase CC screening uptake among social network ...
