Masking Ability of CAD‐CAM Materials at Different Thicknesses: A Study on Color, Translucency, and Infinite Optical Thickness

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the masking ability of different thicknesses of CAD‐CAM resin‐matrix and feldspar porcelain materials. Materials and Methods Specimens (Ø7.5 mm, thickness 0.5, 1.0, and 1.5 mm, n = 3/material) were fabricated from Lava Ultimate‐LU, Grandio Blocs‐GB, VITA Enamic‐VE, and VITA Mark II‐VM.

Factors controlling lava dome morphology [PDF]

Research suggests that variations in lava dome morphology on different planets will depend much more critically on local gravity and the style of eruption than on the magma composition, ambient temperature, or the relative roles of convective and ...

Novel behavioural assays reveal sex‐specific behavioural syndromes in anemonefish

Journal of Fish Biology, EarlyView.
Abstract Individual differences in behaviour and behavioural plasticity have been extensively studied in a variety of animals across the phylogenetic spectrum. Amphiprion species bring distinct insight into the topic because of their unique life history, mating system, and extraordinary degree of behavioural plasticity associated with protandrous (male‐

Color stability of CAD‐CAM hybrid ceramic materials following immersion in artificial saliva and wine

Journal of Prosthodontics, EarlyView.
Abstract Purpose To examine the color stability of 3D‐printed and milled, interim, and definitive, restorative materials after immersion in artificial saliva and wine for 1, 3, and 6 months. Material and Methods The study used a 2 × 5 factorial design with 10 subgroups, including 2 immersion liquids (artificial saliva and wine) and 5 manufacturing ...

Evidence for Phosphate Metasomatism in an Olivine‐Rich Achondrites

Meteoritics &Planetary Science, EarlyView.
Abstract Brachinites, brachinite‐like achondrites (BLA), and other similar primitive achondrites offer important constraints on differentiation processes of the earliest formed planetesimals, as they quenched amidst early differentiation processes on their parent body. Geochemical data for all major mineral phases in two previously poorly characterized

Volcanic features of Hawaii. A basis for comparison with Mars [PDF]

Despite the difference in size Martian and Hawaiian volcanoes have numerous characteristics in common. Specific features such as lava channels, collapsed lava tubes, levees and flow fronts, all very common in Hawaii, are also abundant on the flanks of ...

Textural coarsening as the cause for impact‐melt like plagioclase crystal size distributions and subtle layering in high‐Al basalt 14053

Meteoritics &Planetary Science, EarlyView.
Abstract High‐Al Apollo 14 basalt 14053 has been identified as an endogenous partial melt product from the lunar interior based on geochemical analyses, specifically low abundances of highly siderophile elements, but exhibits textural characteristics similar to those of impact melts. Prior studies of this sample have described mineralogical differences

Evidence of Intraspecific Adaptive Variation in the American Pika (Ochotona princeps) on a Continental Scale Using a Target Enrichment and Mitochondrial Genome Skimming Approach

Molecular Ecology, EarlyView.
ABSTRACT Montane landscapes present an array of abiotic challenges that drive adaptive evolution amongst organisms. These adaptations can promote habitat specialisation, which may heighten the risk of extirpation from environmental change. For example, higher metabolic rates in an endothermic species may contribute to heightened cold tolerance, whilst ...

Fascicular/Purkinje Tissue Colocalized With Scar in Cardiomyopathy Patients Undergoing Ventricular Fibrillation Ablation

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Ventricular fibrillation (VF) is a poorly understood arrhythmia that is one of the main mechanisms of sudden cardiac death in patients with structural heart disease (SHD). Fascicular and Purkinje tissue (FPT) has been implicated in VF.
