Near-Capacity Irregular Bit-Interleaved Coded Modulation [PDF]

, 2008
An Irregular Bit-Interleaved Coded Modulation based Iterative Decoding (Ir-BICM-ID) aided scheme is proposed. The irregularity of the scheme pervades the three basic components of BICM-ID, namely the encoder, the unity-rate precoder and the bit-to-symbol

Bridging the Energy Balance Gap in Eddy‐Covariance Measurements: Insights From Standardized Network Data

Global Change Biology, Volume 32, Issue 5, May 2026.
Written Summary: Measuring energy exchanges between land and atmosphere is fundamental to understanding climate, but these measurements are systematically incomplete, with 20%–40% of energy consistently unaccounted for. Analyzing data from 84 sites worldwide, we show that carefully tracking all energy components and applying strict data quality filters

Trellis-coded multidimensional phase modulation

IEEE Transactions on Information Theory, 1990
A 2L-dimensional multiple phase-shift keyed (L*MPSK) signal set is obtained by forming the Cartesian product of L two-dimensional MPSK signal sets. A systematic approach to partitioning L*MPSK signal sets that is based on block coding is used. An encoder system approach is developed.

Advancing Dry Electroencephalography With Scalable, Soft, and Transcranial Magnetic Stimulation‐Compatible Ti3C2Tx MXene Electrodes for Research and Clinical‐Grade Applications

Advanced Science, Volume 13, Issue 21, 13 April 2026.
Dry soft Ti3C2Tx MXene electroencephalography (EEG) electrodes provide low impedance (2.1 ± 1.8 kΩ at 10 Hz), long‐term stability, and enable safe simultaneous EEG and transcranial magnetic stimulation (TMS). Across scalp sites, hair types, and recording paradigms, including steady state visual evoked potentials (SSVEP), clinical EEG, and mobile EEG ...
