The imprint of crustal density heterogeneities on regional seismic wave propagation [PDF]
, 2016 Density heterogeneities are the source of mass transport in the Earth. However, the 3-D density structure remains poorly constrained because travel times of seismic waves are only weakly sensitive to density.

IEEE Access, 2018 In this paper, we address a number of weaknesses of the windowed decoding of spatially coupled low-density parity-check (SC LDPC) codes and propose three modifications that simultaneously improve its performance, complexity, and latency.

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. With channel symmetry as one of its fundamental assumptions, density evolution (DE) has been widely and successfully applied to different channels, including binary erasure channels, binary ...

Global imaging of the Earth's deep interior: seismic constraints on (an)isotropy, density and attenuation [PDF]
, 2013 Seismic tomography is the principal tool to probe the deep interior of the Earth. Models of seismic anisotropy induced by crystal alignment provide insight into the underlying convective motion, and variations of density allow us to discriminate between ...

On the Evolution of the Central Density of Quiescent Galaxies [PDF]
The Astrophysical Journal Letters, 2017 Abstract We investigate the origin of the evolution of the population-averaged central stellar mass density (Σ1) of quiescent galaxies (QGs) by probing the relation between stellar age and Σ1 at z ∼ 0. We use the Zurich ENvironmental Study (ZENS), which is a survey of galaxy groups with a large fraction of satellite galaxies. QGs shape a

Efficient Implementation of Density Evolution for Punctured Polar Codes
IEEE Access, 2019 Polar codes asymptotically achieve the symmetric capacity of arbitrary binary-input discrete memoryless channels under low-complexity sequential decoding algorithms such as successive cancellation decoding.

Design Strategies for Large Current Density Hydrogen Evolution Reaction
Frontiers in Chemistry, 2022 Hydrogen energy is considered one of the cleanest and most promising alternatives to fossil fuel because the only combustion product is water. The development of water splitting electrocatalysts with Earth abundance, cost-efficiency, and high performance

A Simple Model for Quasar Density Evolution [PDF]
, 2007 It is widely agreed upon that AGN and Quasars are driven by gas accretion onto a supermassive black hole. The origin of the latter however still remains an open question. In this work we present the results of an extremely simple cosmological model combined with an evolutionary scenario in which both the formation of the black hole as well as the gas ...
