Space-Time Turbo Coded Modulation: Design and Applications

EURASIP Journal on Advances in Signal Processing, 2002
A design method for recursive space-time trellis codes and parallel-concatenated space-time turbo coded modulation is proposed that can be applied to an arbitrary existing space-time trellis code.

Cucumber green mottle mosaic virus: A persistent seed‐borne threat to cucurbits

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Cucumber green mottle mosaic virus (CGMMV) is a highly stable, seed‐borne tobamovirus that threatens global cucurbit production. Its efficient mechanical and seed transmission, long‐term environmental persistence, and the spread of Clade II CGMMV isolates drive its rapid dissemination and cause severe yield losses.

Performance of Antenna Diversity with Turbo Trellis Coded Modulation Over Nakagami Channels

Electrica, 2019
In this paper, we will use the Space Time Block codes for antenna diversity, and the performance of Space-Time – Turbo Trellis Coded Modulation (ST-TTCM) is investigated over Nakagami channels.

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 ...
