XFDMSync

This is the v1.0.1 release of XFDMSync, a GNU Radio Out-Of-Tree (OOT) module. The XFDMSync GNU Radio OOT module provides optimized blocks for multicarrier synchronization. During development, the main targets for multicarrier systems are OFDM and GFDM. Algorithmically, the module relies on an improved Schmidl&Cox algorithm according to Awoseyila. This maintenance release improves references and release information

polar-codes

The v1.0.1 maintenance release of polar-codes The polar-codes project is a library and simulation tool for a Forward Error Correcting (FEC) scheme named "Polar Codes". A very promising group of codes that have low encoding and decoding latency with high FER-performance. The polar-codes project provides optimized decoders that are targeted towards AVX2 SIMD instructions. This release removes the optional pybind11 submodule because it is no longer necessary. Moreover, a lot of documentation, especially references, are added. This might improve the understanding of the implementation

Evidence for additive and synergistic action of mammalian enhancers during cell fate determination

Enhancer activity drives cell differentiation and cell fate determination, but it remains unclear how enhancers cooperate during these processes. Here we investigate enhancer cooperation during transdifferentiation of human leukemia B-cells to macrophages. Putative enhancers are established by binding of the pioneer factor C/EBPα followed by chromatin opening and enhancer RNA (eRNA) synthesis from H3K4-monomethylated regions. Using eRNA synthesis as a proxy for enhancer activity, we find that most putative enhancers cooperate in an additive way to regulate transcription of assigned target genes. However, transcription from 136 target genes depends exponentially on the summed activity of its putative paired enhancers, indicating that these enhancers cooperate synergistically. The target genes are cell type-specific, suggesting that enhancer synergy can contribute to cell fate determination. Enhancer synergy appears to depend on cell type-specific transcription factors, and such interacting enhancers are not predicted from occupancy or accessibility data that are used to detect superenhancers.Fuinding: Max-Planck-Gesellschaft (Open-access funding), Deutsche Forschungsgemeinschaft (SFB860), Deutsche Forschungsgemeinschaft (SPP1935), Deutsche Forschungsgemeinschaft (SPP2191), European Research Council (693023

GNU Radio

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available, low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in hobbyist, academic, and commercial environments to support both wireless communications research and real-world radio systems
