In this paper, we get certain the lump-trigonometric solutions and rogue waves with predictability of a (2+1)-dimensional Konopelchenko–Dubrovsky equation in fluid dynamics assistance Maple based on Hirota bilinear form. We first construct general quadratic form to lump solution for referred model. At same time are concluded plenty solutions, which localized all directions space. The analytical obtained employed investigation impacts parameters type solutions. Moreover, when is cut by...

In this study, received dose of CLB was calculated compared between two radiotherapy techniques, including physical stationary motorized wedged fields. Materials Methods: Forty female patients undergoing with supraclavicular involvement were randomly selected. Twenty treated tangential fields using wedges twenty wedges. Three thermo-luminescent dosimeters...
We focused on solitonic phenomena in wave propagation which was extracted from a generalized breaking soliton system (3 + 1)-dimensions. The model describes the interaction between Riemann and long via two space variable nonlinear media. Abundant double-periodic soliton, breather multiple rogue solutions to by Hirota bilinear form mixture of exponentials trigonometric functions are presented.

The CMS experiment, located at the Large Hadron Collider (LHC) in CERN, has a redundant muon system composed by three different gaseous detector technologies: Cathode Strip Chambers (in forward regions), Drift Tubes central region), and Resistive Plate (both its regions). All are used for reconstruction triggering. RPC confers robustness redundancy to trigger. operation challenging background pileup conditions of LHC environment is presented. provides information all track finders thus...
In this work, numerous rogue wave solution strategy (MRWSS) agreeing to the Hirota bilinear hypothesis is utilized.

Four double-gap CMS resistive plate chambers are being tested at the CERN Gamma Irradiation Facility to determine performance and aging effects expected conditions of High Luminosity-Large Hadron Collider. Results up an integrated charge 290 millicoulomb/cm2 reported.
The high luminosity expected from the HL-LHC will be a challenge for CMS detector. increased rate of particles coming collisions and radioactivity induced in detector material could cause significant damage result progressive degradation its performance.
