Quantizing Gravitational Collapse

, 2004
I summarize some results obtained from a canonical quantization of gravitational collapse. The quantization is carried out in Kuchar variables on the LeMaitre-Tolman-Bondi family of spacetimes.

The Impact of Deviation of the Stun Shot from the Ideal Point on Motor Paralysis in Cattle

Animals, 2020
The effect on motor paralysis of a deviation in the stun shot placement from the ideal point on cattle skulls was monitored in 627 bovine animals (271 bulls and 356 cows) stunned with a captive bolt during slaughter in a slaughterhouse.

Comparison of the collapse frequency and failure probability of buildings

Acta Polytechnica CTU Proceedings, 2022
In a previous study, the collapse frequencies and associated mortalities of buildings were compiled based on various publications. The investigation showed a considerable scattering of collapse frequencies depending on the countries.

Numerical simulations of non-spherical bubble collapse [PDF]

, 2009
A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...

Conditional Collapse

Mind, 2023
AbstractIndicative and subjunctive conditionals are in non-complimentary distribution: there are conversational contexts at which both are licensed (Stalnaker 1975; Karttunen and Peters 1979; von Fintel 1998). This means we can ask an important, but under-explored, question: in contexts which license both, what relations hold between the two?

Research on Ultrasonic Guided Wave Damage Detection in Internally Corroded Pipes with Curved Random Surfaces

Applied Sciences
To accurately simulate the progression of pipeline corrosion, this paper proposes a three-dimensional corrosion modeling method for curved random surfaces based on spatial frequency composition.

Magnetized Dusty Black Holes and Wormholes

Universe, 2021
We consider the generalized Tolman solution of general relativity, describing the evolution of a spherical dust cloud in the presence of an external electric or magnetic field. The solution contains three arbitrary functions f(R), F(R) and τ0(R), where R

Diffuse Supernova Neutrino Background from extensive core-collapse simulations of $8$-$100 {\rm M}_\odot$ progenitors

, 2017
We revisit the diffuse supernova neutrino background in light of recent systematic studies of stellar core collapse that reveal the quantitative impacts of the progenitor conditions on the collapse process. In general, the dependence of the progenitor on
