Scalable video/image transmission using rate compatible PUM turbo codes [PDF]

, 2007
The robust delivery of video over emerging wireless networks poses many challenges due to the heterogeneity of access networks, the variations in streaming devices, and the expected variations in network conditions caused by interference and coexistence.

A multi‐source fusion and dynamic verification framework for scientific knowledge graph construction: Methods, evaluation, and applications

AI Magazine, Volume 47, Issue 2, Summer 2026.
Abstract The exponential growth of scientific literature—over 2.5 million papers and 3.5 million patents annually—poses critical challenges for knowledge discovery. To address these, we propose SCIMKG (Scientific Knowledge Graph), a framework for constructing scientific knowledge graphs via multi‐source heterogeneous multi‐source.

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, Volume 36, Issue 50, 22 June 2026.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Patents and Supra‐Competitive Prices: Evidence From Consumer Products

Journal of Empirical Legal Studies, Volume 23, Issue 2, Page 172-204, June 2026.
ABSTRACT A patent system is a central tool in innovation policy. The prospect of monopolistic pricing supposedly encourages firms to innovate. However, there is scant empirical evidence supporting the existence of higher markups for patent‐protected products.

Cytokinin downregulates Photosystem II photochemistry during prolonged darkness in a phytochrome B‐dependent manner

New Phytologist, Volume 250, Issue 6, Page 3846-3866, June 2026.
Cytokinin–phyB signaling modulates PSII photochemistry during prolonged darkness. Summary Cytokinins (CKs) delay dark‐induced senescence, but how they tune photosynthetic function in darkness remains unclear. We investigated the effects of classical aromatic CK benzylaminopurine and CK‐derived compound 1‐(2‐methoxyethyl)‐3‐(1,2,3‐thiadiazol‐5‐yl)urea ...

Lipo‐Glc‐1,6‐P2: A Bioprecursor Prodrug for Phosphomannomutase‐2 Congenital Disorder of Glycosylation

IUBMB Life, Volume 78, Issue 4, April 2026.
ABSTRACT Phosphomannomutase‐2 (PMM2) deficiency leads to the prominent Congenital Disorder of Glycosylation (CDG), a rare disease currently lacking effective treatment options. The complete absence of PMM2 activity is incompatible with life, and all patients carry at least one missense destabilising variant that allows residual enzymatic function. This

Concatenated Turbo/LDPC codes for deep space communications: performance and implementation [PDF]

, 2013
Deep space communications require error correction codes able to reach extremely low bit-error-rates, possibly with a steep waterfall region and without error floor. Several schemes have been proposed in the literature to achieve these goals.

Plastid Engineering for Photosynthesis‐Driven Synthesis of Hyaluronic Acid in Tobacco

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2541-2558, April 2026.
ABSTRACT Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating units of N‐acetylglucosamine and glucuronic acid. High moisture retention, viscoelasticity and biocompatibility are unique features that make HA polymers attractive compounds for medical applications and aesthetic purposes.

The Vegan Villain Sets Out to The End of Summer: Functionalized Coatings as Biohybrid UV‐Sensors

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This study introduces biohybrid coatings incorporating E. coli biomass expressing photoconvertible fluorescent proteins as UV‐A responsive elements. Upon irradiation at 400 nm, the coatings exhibit an irreversible fluorescence shift from green to red within 15 min. Notably, the photoconversion capability is retained after >1 year of storage.

An EXIT-Chart Aided Design Procedure for Near-Capacity N-Component Parallel Concatenated Codes [PDF]

, 2010
Shannon’s channel capacity specifies the upper bound on the amount of bits per channel use. In this paper, we explicitly demonstrate that twin-component turbo codes suffer from a capacity loss, when the component code rate is less than unity, which is ...
