Turbo trellis-coded hierarchical modulation assisted decode-and-forward cooperation

Hierarchical modulation, 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 ...

MIMO-aided near-capacity turbo transceivers: taxonomy and performance versus complexity

, 2012
In this treatise, we firstly review the associated Multiple-Input Multiple-Output (MIMO) system theory and review the family of hard-decision and soft-decision based detection algorithms in the context of Spatial Division Multiplexing (SDM) systems.

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

Advanced Healthcare Materials, Volume 15, Issue 18, 15 May 2026.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Integrated Wireless Multimedia Turbo-Transceiver Design Approaching the Rayleigh Channel's Capacity: Interpreting Shannon's Lessons in the Turbo-Era

, 2004
Claude Shannon's pioneering work quantified the performance limits of communications systems operating over classic wireline Gaussian channels. However, his source and channel coding theorems were derived for a range of idealistic conditions, which may ...

Microglia Mitochondria Support Neuronal Maturation via Metabolic and Transcriptional Reprogramming in Human 3D In Vitro Brain Model

Advanced Science, Volume 13, Issue 25, 4 May 2026.
xx xx. ABSTRACT Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by disrupted neuronal circuit maturation. Emerging evidence implicates microglial function and mitochondrial regulation as contributors to ASD‐associated biology, yet the mechanisms linking these processes to neuronal development remain poorly defined ...

Performance Evaluation of Parallel Concatenated Chaos Coded Modulations

Journal of Communications Software and Systems, 2008
In this article we study the performance of a class of parallel concatenated encoders similar to a turbo trellis coded modulation, but where the constituent encoders are chaos coded modulators.

Age‐related behavioral and molecular landmarks in new mouse models for studying Alzheimer's disease in Down syndrome

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Down syndrome (DS) is the leading genetic cause of intellectual disability and Alzheimer's disease (AD), with over 90% of individuals developing AD‐related dementia (DSAD). The triplication of the APP gene on chromosome 21 drives early amyloid‐β (Aβ) accumulation, but other Hsa21 genes also contribute to pathology.

VGLL3 Regulates DAPK2‐Mediated Autophagy During Osteoblast Differentiation

BioFactors, Volume 52, Issue 3, May/June 2026.
VGLL3 regulates autophagic activity during osteoblast differentiation and is associated with DAPK2‐mediated autophagy. Overexpression of Dapk2 partially restores autophagy and osteogenic differentiation in Vgll3‐deficient osteoblasts. ABSTRACT Vestigial‐like family member 3 (VGLL3), a transcriptional cofactor of the TEA domain family, has been ...
