A Class of Quantum LDPC Codes Constructed From Finite Geometries

, 2008
Low-density parity check (LDPC) codes are a significant class of classical codes with many applications. Several good LDPC codes have been constructed using random, algebraic, and finite geometries approaches, with containing cycles of length at least ...

Quantum low density parity check codes

, 2022
Low density Parity Check (LDPC) Codes are asymptotically good codes with a fast decoding algorithm, and hence have extensive applications. A lot of work has been done on constructing a quantum code with LDPC properties. Recent breakthroughs show that it is possible to construct a quantum LDPC code that is asymptotically good (meaning the distance of ...

Codeword Structure Analysis for LDPC Convolutional Codes

Information, 2015
The codewords of a low-density parity-check (LDPC) convolutional code (LDPC-CC) are characterised into structured and non-structured. The number of the structured codewords is dominated by the size of the polynomial syndrome former matrix

Social cohesion among Syrian and Turkish children, adolescents, and young adults in Turkey

International Migration, EarlyView.
Abstract Turkey has received a large influx of Syrian refugees since the start of Syrian civil war in 2011. Integration and social cohesion have become important issues for public policy in Turkey. We study social cohesion among young Turkish nationals and Syrian refugees.

Doped low-density parity-check codes

Digital Communications and Networks
In this paper, we propose a doping approach to lower the error floor of Low-Density Parity-Check (LDPC) codes. The doping component is a short block code in which the information bits are selected from the coded bits of the dominant trapping sets of the LDPC code.

Mother–infant stress contagion? Effects of an acute maternal stressor on maternal caregiving behavior and infant cortisol and crying

Journal of Child Psychology and Psychiatry, EarlyView.
Background Postpartum maternal distress has been associated with adverse infant outcomes. A potential pathway of how maternal distress affects infant outcomes could be alterations in maternal caregiving behavior. However, the associations between maternal distress, caregiving behavior, and infant outcomes have never been tested in a controlled ...

Attentional Uniqueness and Firm Performance: The Mediating Role of Growth Actions

Journal of Management Studies, EarlyView.
Abstract The attention‐based view posits that a firm's allocation of attention to particular issues directly influences its actions and performance. Yet, the impact of attentional uniqueness – how the pattern of a firm's attentional allocation diverges from its competitors within the same industry – on behaviour and performance remains underexplored ...
