The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose reactor neutrino experiment
currently under construction in Jiangmen, China. The main physics goal of Juno is to determine the neutrino mass hierarchy by measuring the reactor antineutrino flux from two Nuclear Power Plants located in southern China.
The experiment will be a record in energy resolution (3% at 1 MeV)...

The Inner Tracking System (ITS) plays a key role in the precise determination of secondary vertices in high energy hadron collisions in A Large Ion Collider Experiment (ALICE) at the Large Hadron Collider (LHC). After the upgrade in 2020 the beam luminosity of the LHC will be increased by a factor of ten refers to Pb-Pb collisions. This will provide new opportunities of studies of rare...

Cold nuclear matter effects such as parton energy loss in nuclear matter and nuclear modification of parton distribution functions in the Drell-Yan process in πA and pA collisions have been extensively studied during the last 30 years. Various theoretical models have been proposed to explain these effects, but its full understanding is still lacking.
COMPASS studies nuclear effects in...

Scientists in high energy physics produce their output mostly in form of histograms. Set of histograms are saved in output
file for each grid job. As the next step is to merge these files/histograms to one file where scientist can produce final plots
for publication. Merging of these out files may be done sequentially as one job or do it in parallel via binary tree algorithm
as it is done...

At present, in Dubna, Russia a new acceleration complex NICA is being constructed. One of its two detectors and most integral parts of the collider (NICA) is a Multi-Purpose Detector (MPD). MPD experiment is intended for study of properties of dense baryonic matter. One of the most important parts of MPD is Forward Hadron Calorimeter (FHCal), whose purpose is to measure centrality and...

For several reasons, the title families of compounds are of increasing interest for theoretical investigation of composition-structure-properties relations. For instance, their wide range practical applications and thermodynamic stability are closely related to possible defects in the structure such as doping, vacancies, and atomic site substitutions. Recently, we have developed several...
