Density Evolution for Asymmetric Memoryless Channels [PDF]
IEEE Transactions on Information Theory, 2005 Density evolution is one of the most powerful analytical tools for low-density parity-check (LDPC) codes and graph codes with message passing decoding algorithms.

Evolution of Liouville density of a chaotic system [PDF]
Physical Review E, 1995 An area-preserving map of the unit sphere, consisting of alternating twists and turns, is mostly chaotic. A Liouville density on that sphere is specified by means of its expansion into spherical harmonics.

Evolution of energy density fluctuations in A+A collisions [PDF]
Physics of Particles and Nuclei Letters, 2011 Two-particle angular correlation for charged particles emitted in Au+Au collisions at the center-of-mass of 200 MeV measured at RHIC energies revealed novel structures commonly referred to as a near-side ridge.

Cosmological Evolution with Negative Energy Densities
Astrophysics, 2022 For general number of spatial dimensions we investigate the cosmological dynamics driven by a cosmological constant and by a source with barotropic equation of state. It is assumed that for both those sources the energy density can be either positive or negative. Exact solutions of the cosmological equations are provided for flat models.

THE EVOLUTION OF THE NUMBER DENSITY OF COMPACT GALAXIES [PDF]
The Astrophysical Journal, 2013 We compare the number density of compact (small size) massive galaxies at low and high redshift using our Padova Millennium Galaxy and Group Catalogue (PM2GC) at z=0.03-0.11 and the CANDELS results from Barro et al. (2013) at z=1-2. The number density of local compact galaxies with luminosity weighted (LW) ages compatible with being already passive at ...

Probability density evolution filter
Probabilistic Engineering Mechanics, 2022 Based on probability density evolution method (PDEM) and Bayes law, a new filter strategy is proposed, in which the prior probability of system state of interest is predicted by solving the general density evolution equation (GDEE), the posterior probability of system state is then updated in terms of Bayes formula.

Weighted BATS Codes with LDPC Precoding
Entropy, 2023 Batched Sparse (BATS) codes are a type of network coding scheme that use a combination of random linear network coding (RLNC) and fountain coding to enhance the reliability and efficiency of data transmission. In order to achieve unequal error protection

Wavelet analysis of the formation of the cosmic web [PDF]
, 2011 According to the modern cosmological paradigm galaxies and galaxy systems form from tiny density perturbations generated during the very early phase of the evolution of the Universe. Using numerical simulations we study the evolution of phases of density
