Prevalence of malocclusion and orthodontic treatment need in 10-year-old New Zealand children

Australasian Orthodontic Journal, 2000
The need for orthodontic treatment was determined in a random sample of 10-year-old Dunedin, New Zealand schoolchildren using the Dental Aesthetic Index (DAI); an index based on the social acceptability of dental appearance.

From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

Advanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Radar Cross Section Reduction of Microstrip Patch Antenna using Metamaterial Techniques [PDF]

Journal of Electrical and Electronics Engineering, 2021
Radar cross section (RCS) reduction has become one of the critical research areas in recent years. The RCS of the target should be small to avoid detection.

Single‐Nucleus Atlas of Spinal Sarcopenia Patients Reveals Disruption of Quiescent and Regenerative Satellite Cell Niches in Fatty‐Infiltrated Muscle

Advanced Science, EarlyView.
Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

The comprehension of Italian relative clauses in poor readers and in children with Specific Language Impairment

Glossa, 2017
Children with Specific Language Impairment (SLI) and children with Developmental Dyslexia (DD) have problems comprehending relative clauses (RCs) and find object RCs more difficult than subject RCs, as do typically developing children.

Wood Carbon Sponge/SiO2 Aerogel Composites with Anisotropic Broadband Microwave Absorption, Elastic Resilience, and Thermal Insulation

Advanced Science, EarlyView.
Anisotropic wood carbon sponge/SiO2 aerogel composites are constructed, revealing a robust direction‐dependent permittivity ordering (tangential > radial > axial). The radial direction delivers an ultra‐broadband effective absorption bandwidth of 11.6 GHz at only 4.95 mm, while the tangential direction offers superior compressibility and thermal ...
