Evaluation of aesthetic integration between composite restorations and natural tooth in NCCL: a case report [PDF]
, 2015 NCCL (non carious cervical lesion) is defined as irreversible loss of dental hard tissue that does not involve bacteria. It consists of erosion, attrition, abrasion and abfraction that rarely occur alone.

Autosomal Recessive Cerebellar Ataxias: Translating Genes to Therapies
Annals of Neurology, EarlyView.Autosomal recessive cerebellar ataxias are disabling neurodegenerative genetic conditions affecting balance and coordination. Advancements in genomic testing have improved diagnosis, leading to a new focus on the development of targeted precision therapeutics addressing cellular, biochemical, and genetic disease mechanisms with a resulting emphasis on ...

New generation methods for spur, helical, and spiral-bevel gears [PDF]
New methods for generating spur, helical, and spiral-bevel gears are proposed. These methods provide the gears with conjugate gear tooth surfaces, localized bearing contact, and reduced sensitivity to gear misalignment.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning
The Anatomical Record, EarlyView.Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Reconstruction and subsurface lattice distortions in the (2 × 1)O-Ni(110) structure: A LEED analysis [PDF]
, 1990 LEED analysis of the reconstructed (2 × 1)O-Ni(110) system clearly favors the “missing row” structure over the “saw-tooth” and “buckled row” models. By using a novel computational procedure 8 structural parameters could be refined simultaneously, leading

Myological and osteological approaches to gape and bite force reconstruction in Smilodon fatalis
The Anatomical Record, EarlyView.Abstract Masticatory gape and bite force are important behavioral and ecological variables. While much has been written about the highly derived masticatory anatomy of Smilodon fatalis, there remains a great deal of debate about their masticatory behaviors.

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin
The Anatomical Record, EarlyView.Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.
