Explosive crystallization mechanism of ultradisperse amorphous films [PDF]

, 1999
The explosive crystallization of germanium ultradisperse amorphous films is studied experimentally. We show that crystallization may be initiated by local heating at the small film thickness but it realizes spontaneously at the large ones.

Axion-like Particles from Nearby Type Ia Supernovae [PDF]

EPJ Web of Conferences, 2022
Axion-like particles (ALPs) are a class of hypothetical pseudo-scalar particles and can be created in hot astrophysical plasma through the interaction between photons. I calculate the production of ALPs in type Ia supernovae.

Experiments probing clustering effects in explosive nucleosynthesis

Frontiers in Physics, 2023
Nuclear clustering affects the nucleosynthesis occurring in a number of astrophysical environments. Highly-clusterized nuclear states typically occur near particle thresholds and therefore can produce dramatic impacts on the nuclear reaction rates.

Explosive Collisions at RHIC? [PDF]

, 2001
Motivated by experimental results from RHIC, we suggest how a condensate for the Polyakov loop might produce explosive behavior at the QCD phase transition.

Predicting Miner Localization in Underground Mine Emergencies Using a Hybrid CNN-LSTM Model with Data from Delay-Tolerant Network Databases

Applied Sciences
Underground mining environments are highly hazardous, often prone to gas explosions, cave-ins, and fires that may trap miners during emergencies. The accurate, real-time localization of miners is vital for effective self-escape and rescue operations ...

Explosive Welding of Aluminum, Titanium and Zirconium to Copper Sheet Metal [PDF]

, 1985
The main material properties affecting the explosive weldability of a certain metal combination are the yield strength, the ductility, the density and the sonic velocity of the two metals. Successful welding of the metal combination depends mainly on the
