Current measurements of Standard Model parameters suggest that the electroweak vacuum is metastable. This metastability has important cosmological implications, because large fluctuations in Higgs field could trigger decay early Universe. For false to survive, interactions which stabilize during inflation---e.g., inflaton-Higgs or nonminimal couplings gravity---are typically necessary. However,...

Semi-coke has difficulties with stable ignition and high-efficiency combustion due to its low volatile content. Preheating in a circulating fluidized bed before offers novel method for the improvement of fuel properties. During preheating, semi-coke was converted preheated composed coal gas char. When increasing preheating temperature, ratio CO/CO2 significantly increased, while CH4/CO2 remaine...

This study investigated the dosimetric properties of various electronic components extracted from a new generation mobile phone using optically stimulated luminescence and thermoluminescence. The studied resistors exhibit high linearity in the dose range of interest, signal repeatibility and reproducibility, along with a minimum detectable dose of 16 mGy after preheating.
