On the Collision of Relativistic Shock Waves and the Large Scale Structure of the Universe
Universe, 2020 The solution to the problem of symmetric collision of two relativistic shock waves is given and limiting cases are investigated: Newtonian mechanics and ultrarelativistic mechanics. The results are correlated with the presence of known superclusters and "

Concentration for One and Two Species One-Dimensional Reaction-Diffusion Systems [PDF]
, 1995 We look for similarity transformations which yield mappings between different one-dimensional reaction-diffusion processes. In this way results obtained for special systems can be generalized to equivalent reaction-diffusion models.

Calculation of Low-Energy Positron-Atom Scattering with Square-Integrable Wavefunctions
Atoms, 2022 The variational method is applied to the low-energy positron scattering and annihilation problem. The ultimate aim of the investigation is to find a computationally economical way of accounting for strong electron–positron correlations, including the ...

Indirect Dark Matter Signatures in the Cosmic Dark Ages I. Generalizing the Bound on s-wave Dark Matter Annihilation from Planck [PDF]
, 2015 Recent measurements of the cosmic microwave background (CMB) anisotropies by Planck provide a sensitive probe of dark matter annihilation during the cosmic dark ages, and specifically constrain the annihilation parameter $f_\mathrm{eff} \langle \sigma v \

Annihilation of vortex dipoles in an Oblate Bose-Einstein Condensate
, 2012 We theoretically explore the annihilation of vortex dipoles, generated when an obstacle moves through an oblate Bose-Einstein condensate, and examine the energetics of the annihilation event.

Substructure Boosts to Dark Matter Annihilation from Sommerfeld Enhancement [PDF]
, 2009 The recently introduced Sommerfeld enhancement of the dark matter annihilation cross section has important implications for the detection of dark matter annihilation in subhalos in the Galactic halo.

Starting from Kant’s professed embarrassment at the idea of being found praying, the chapter explores Kant’s underlying assumptions about the character of autonomous freedom that he sees as integral to human flourishing. This is seen as further radicalized in Fichte but countered in Schleiermacher’s view of human beings as “absolutely dependent” on God,

Annihilation of positrons, emitted at β+-decay with electrons of the daughter's atom [PDF]
Ядерна фізика та енергетика, 2010 The processes of photon creation or atom ionization during annihilation of positron with other electron of daughter’s atom at β+-decay are considered.

Phase transition in annihilation-limited processes
, 2006 A system of particles is studied in which the stochastic processes are one-particle type-change (or one-particle diffusion) and multi-particle annihilation.
