Experimental and numerical study on homogenisation of BCV bentonite using dual density samples [PDF]
E3S Web of Conferences, 2023 Homogenisation of bentonite materials is an essential feature for its sealing function in radioactive waste repositories. Presented study is focused on the laboratory investigation of the homogenisation of Czech BCV bentonite (Ca/Mg type).

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.

An analysis of the evolving comoving number density of galaxies in hydrodynamical simulations [PDF]
, 2015 The cumulative comoving number-density of galaxies as a function of stellar mass or central velocity dispersion is commonly used to link galaxy populations across different epochs.

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 ...

Fixed Points and Stability of Density Evolution [PDF]
Communications in Information and Systems, 2004 Density evolution is a dynamic system in a space of probability distributions repre- senting the progress of iterative decoders in the infinite block length limit. In this paper we establish some basic results concering this process. In particular we show that the decoding threshold is equivalent to to appearance of non-trivial fixed point solutions to

Clade density and the evolution of diversity-dependent diversification
Nature Communications, 2023 The assumption of an ecological limit to the number of species in a given region is frequently invoked in evolutionary studies, yet its empirical basis is remarkably meager. We explore this assumption by integrating data on geographical distributions and

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

IEEE Access, 2019 Impulsive noise (IN) constitutes a limiting factor in power-line communication systems, especially in those relying on orthogonal frequency division multiplexing (OFDM). If a single time-domain sample is contaminated by an impulse, all subcarriers become
