On connection of variations between hard cosmic ray flux, temperature and cardiovascular diseases in Vilnius and sunspot number during 2001–2012

open access: yesJournal of Environmental Engineering and Landscape Management, 2015
The connection has been found between the course of cardiovascular diseases (CVD) and the hard cosmic ray flux (HCRF) near the ground surface in Vilnius. The course of air temperature and number of sunspot was simultaneously considered. The investigation

QCD Splitting/Joining Functions at Finite Temperature in the Deep LPM Regime

open access: yes, 2008
There exist full leading-order-in-alpha_s numerical calculations of the rates for massless quarks and gluons to split and join in the background of a quark-gluon plasma through hard, nearly collinear bremsstrahlung and inverse bremsstrahlung.

Investigating Generalized Parton Distribution in Gravity Dual

open access: yes, 2011
Generalized parton distribution (GPD) contains rich information of partons in a hadron, including transverse profile, and is also non-perturbative information necessary in describing a variety of hard processes, such as meson leptoproduction and double ...

Application of Long-Distance Drilling and Blasting Technology to Prevent Rock Bursts in High-Level Roofs

open access: yesApplied Sciences
In view of the high-level, thick, and hard roof in a mine in Shaanxi, it is difficult for existing technology to solve the problem of frequent rock bursts, which are caused by the direct weakening of the whole underground layer.
