Low Complexity Iterative Receiver Design for Shallow Water Acoustic Channels
EURASIP Journal on Advances in Signal Processing, 2010 An adaptive iterative receiver structure for the shallow underwater acoustic channel (UAC) is proposed using a decision feedback equalizer (DFE) and employing bit-interleaved coded modulation with iterative decoding (BICM-ID) in conjunction with ...

Journal of Integrative Plant Biology, EarlyView.In Ficus carica fruit, the MAP kinase FcMAPK4 phosphorylates the NAC transcription factor FcNOR, which cooperates with ethylene response factor FcERF5 to activate the pectin degradation gene FcPG12, thereby promoting rapid softening of fig fruit. ABSTRACT Rapid softening of fig (Ficus carica L.) fruit during ripening leads to extremely short shelf life;

Near-Capacity Transceiver Design Using Exit-Curve Fitting: Three-Stage Turbo Detection of Irregular Convolutional Coded Joint Sphere-Packing Modulation and Space-Time Coding [PDF]
, 2007 Conventional two-stage turbo-detected schemes typically suffer from a Bit Error Rate (BER) floor, preventing them from achieving infinitesimally low BER values, especially, when the inner coding stage is of non-recursive nature.

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia
Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Five Decades of Hierarchical Modulation and Its Benefits in Relay-Aided Networking
IEEE Access, 2015 Hierarchical modulation (HM), which is also known as layered modulation, has been widely adopted across the telecommunication industry. Its strict backward compatibility with single-layer modems and its low complexity facilitate the seamless upgrading of

Sphere-Packing Modulated Space-Time Coding Using Non-Binary LDPC-Coded Iterative-Detection
, 2008 A recently proposed Space-Time Block Coding (STBC) signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design. In

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development
New Phytologist, EarlyView.Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.
