Prediction and Evaluation of Coal Mine Coal Bump Based on Improved Deep Neural Network

open access: yesGeofluids, 2021
Coal bump prediction is one of the key problems in deep coal mining engineering. To predict coal bump disaster accurately and reliably, we propose a depth neural network (DNN) prediction model based on the dropout method and improved Adam algorithm.

Characterisation of the dip-bump structure observed in proton–proton elastic scattering at $$\sqrt{s}$$ s = 8 TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
The TOTEM collaboration at the CERN LHC has measured the differential cross-section of elastic proton–proton scattering at $$\sqrt{s} = 8\,\mathrm{TeV}$$ s = 8 TeV in the squared four-momentum transfer range $$0.2\,\mathrm{GeV^{2}}< |t| < 1.9\,\mathrm ...
