Communications in Mathematical Physics, 2020 AbstractWe ask the question whether entropy accumulates, in the sense that the operationally relevant total uncertainty about an n-partite system $$A = (A_1, \ldots A_n)$$ A = ( A 1 , … A n ) corresponds to the sum of the entropies of its parts $$A_i$$ A i .

Accumulate-repeat-accumulate-accumulate-codes [PDF]
IEEE 60th Vehicular Technology Conference, 2004. VTC2004-Fall. 2004, 2005 Inspired by recently proposed accumulate-repeat-accumulate (ARA) codes (Abbasfar et al. (2004)), in this paper we propose a channel coding scheme called accumulate-repeat-accumulate-accumulate (ARAA) codes. These codes can he seen as serial turbo-like codes or as a subclass of low density parity check (LDPC) codes, and they have a projected graph or ...

Pyrolysis-gas chromatography-mass spectrometry analyses of oil-bearing fluid inclusions composition
Shiyou shiyan dizhi, 2021 The molecular compositions of oil-bearing fluid inclusions (FIs) are valuable for the research of oil and gas accumulation; however, due to the very trace amount of materials included, the requirements of commercial instruments cannot be satisfied and ...
