There are a huge number of harmonics in the railway power supply system.Accurately estimating the harmonic impedance of the system is the key to evaluating the harmonic emission level of the power supply system.A harmonic impedance estimation method is proposed in this paper, which takes the Gaussian mixture regression (GMR) as the main idea, and i
Woodland caribou (Rangifer tarandus) are threatened in Alberta in part due to the development of oil and gas resources.To inform best management practices for caribou, we assessed how proximity to wellsites influenced caribou habitat selection, and miller multimatic 255 tig kit whether habitat selection varied across wellsite activity phases (i.e.,
Introduction.Rectal large cell neuroendocrine carcinoma (LCNEC) is a best 6.7 powerstroke intercooler pipe upgrade poorly differentiated neoplasm that is very rare and belongs within the poorest prognostic subgroup among primary colorectal neoplasms.Here, we describe a case of LCNEC of the rectum, which highlights the aggressive clinical course and
Ultra-relativistic heavy-ion collisions at energies of RHIC and gildan midnight LHC are considered.For comparison with data the HYDJET++ model, which contains the treatment of both soft and hard processes, is employed.The study focuses mainly on the interplay of ideal hydrodynamics, final state interactions and jets, and its influence on the develo
