Universal Rateless Codes From Coupled LT Codes
Vahid Aref, Rüdiger L. Urbanke
It was recently shown that spatial coupling of individual low-density parity-check codes improves the belief-propagation threshold of the coupled ensemble essentially to the maximu…
Scaling Behavior of Convolutional LDPC Ensembles over the BEC
Pablo M. Olmos, Rüdiger Urbanke
We study the scaling behavior of coupled sparse graph codes over the binary erasure channel. In particular, let 2L+1 be the length of the coupled chain, let M be the number of vari…
Topological Complexity of H-Spaces
Gregory Lupton, Jérôme Scherer
Let X be a (not-necessarily homotopy-associative) H-space. We show that TC_{n+1}(X) = cat(X^n), for n >= 1, where TC_{n+1}(-) denotes the so-called higher topological complexity in…
Protons in lattice confinement: Static pressure on the Y-substituted, hydrated BaZrO3 ceramic proton conductor decreases proton mobility
Qianli Chen, Artur Braun, Alejandro Ovalle +3
Yttrium substituted BaZrO3, with nominal composition BaZr0.9Y0.1O3, a ceramic proton conductor, was subject to impedance spectroscopy for temperatures 300 K < T < 715 K at mechanic…
Evolution of an oxygen NEXAFS transition in the upper Hubbard band in α-Fe2O3 upon electrochemical oxidation
Debajeet K. Bora, Artur Braun, Selma Erat +6
Electrochemical oxidation of hematite (α-Fe2O3) nano-particulate films at 600 mV vs. Ag+/AgCl reference in KOH electrolyte forms a species at the hematite surface which causes a ne…
Fe-resonant valence band photoemission and oxygen NEXAFS study on La1-xSrxFe0.75Ni0.25O3-δ
Selma Erat, Hiroki Wadati, Funda Aksoy +4
Iron resonant valance band photoemission spectra of Sr substituted LaFe0.75Ni0.25 O3-δ have been recorded across the Fe 2p - 3d absorption threshold to obtain Fe specific spectral…
