ATP-Dependent Chromatin Remodellers in Inner Ear Development
Cells, 2023 During transcription, DNA replication and repair, chromatin structure is constantly modified to reveal specific genetic regions and allow access to DNA-interacting enzymes. ATP-dependent chromatin remodelling complexes use the energy of ATP hydrolysis to

An Enhanced Decoding Algorithm for Coded Compressed Sensing with Applications to Unsourced Random Access [PDF]
Sensors, 2022 Unsourced random access (URA) has emerged as a pragmatic framework for next-generation distributed sensor networks. Within URA, concatenated coding structures are often employed to ensure that the central base station can accurately recover the set of ...

The structure of the Tad pilus alignment complex reveals a periplasmic conduit for pilus extension
Nature CommunicationsThe Tad (Tight adherence) pilus is a bacterial appendage implicated in virulence, cell-cell aggregation, and biofilm formation. Despite its homology to the well-characterised Type IV pilus, the structure and assembly mechanism of the Tad pilus are poorly

BiSPARCs for Unsourced Random Access in Massive MIMO [PDF]
Asilomar Conference on Signals, Systems and Computers, 2023 This paper considers the massive MIMO unsourced random access problem in a quasi-static Rayleigh fading setting. The proposed coding scheme is based on a concatenation of a “conventional” channel code (such as, e.g., LDPC) serving as an outer code, and a

Massive Unsourced Random Access: Exploiting Angular Domain Sparsity [PDF]
IEEE Transactions on Communications, 2022 This paper investigates the unsourced random access (URA) scheme to accommodate numerous machine-type users communicating to a base station equipped with multiple antennas. Existing works adopt a slotted transmission strategy to reduce system complexity;

Biometric based Multi-Authority Inner Product Encryption for Electronic Health Record [PDF]
EAI Endorsed Transactions on Pervasive Health and Technology, 2020 INTRODUCTION: Attribute-based encryption enhances the security of electronic health records outsourced to the cloud. At thesame time, single authority attribute based encryption leads to user privacy breech and attribute management complexity.Multi ...

Unsourced Random Access With Coded Compressed Sensing: Integrating AMP and Belief Propagation [PDF]
IEEE Transactions on Information Theory, 2020 Sparse regression codes with approximate message passing (AMP) decoding have gained much attention in recent times. The concepts underlying this coding scheme extend to unsourced random access with coded compressed sensing (CCS), as first demonstrated by
