Evaluating the Probability of Survival and Damage Mechanisms of Resin Matrix Ceramics: Insights Into Wear Progression and Surface Damage Under Fatigue

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study evaluated the probability of survival, failure modes, and fatigue‐induced wear progression, as well as assessed damage tolerance under simulated mastication in two resin matrix ceramics (polymer‐infiltrated ceramic networks (PICN) and resin nanoceramic (RNC)).

Surplus Populations and Socio‐Ecological Conflicts in Latin America: The Case of the Mapuche Struggle in Southern Chile

Journal of Agrarian Change, EarlyView.
ABSTRACT So‐called surplus populations have repeatedly been the focus of critical analyses in recent years. This refers to a large social group that comprises most of the population in the Global South and is characterised by the fact that it is not integrated into the capitalist mode of production to any relevant extent through wage labour.

Biomaterials for Reconstructive Treatment of Peri‐Implantitis

Journal of Periodontal Research, EarlyView.
Reconstructive therapy should be implemented in contained defects. Various bone filler materials with or without a barrier membrane and/or adjunctive biologics may be applied. ABSTRACT Peri‐implantitis is a pathological condition affecting the tissues surrounding dental implants, marked by inflammation of the peri‐implant connective tissue and ...

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

Journal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.
