An Efficient Index Mapping Algorithm for OFDM-Index Modulation
IEEE Access, 2019 An index mapping algorithm that efficiently associates the subcarrier activation pattern (SAP) or constellation mode pattern (CMP) sequences with the index selecting bit (ISB) sequences is proposed to improve the error performances of two OFDM-`index ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Mitigating bit-synchronization errors in Huffman-coding-aided index modulation
, 2018 When utilizing all subcarrier activation patterns (SAPs) in the combinatorial index modulation (IM) scheme, existing techniques either fail to realize the maximum throughput enhancement by using all SAPs or fail to address the bit-level synchronization ...

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
