talon cusp is a dental anomaly also known as an eagle’s talon. it is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. the exact etiology is unknown. the incidence of talon cusp is less than 6%. commonly involved teeth are maxillary incisors, usually unilateral but in some instances bilateral. the classical ra...

Introduction: Since preserving the structure of treated teeth is a critical success factor, studying the effects of tooth structure loss on fracture resistance of the tooth tissue appears necessary. The aim of this study was to evaluate the consequences of the loss of different tissues regarding fracture resistance of teeth undergoing root canal treatment without the use of indirect restoration...

Abstract A transition layer, named the Alfvénic layer (or ATL), has been clearly evidenced near outer boundary of cusp by experimental observations from Cluster mission. This characterized a local value Log M ∼ 1, where is Alfvén Mach number, allows bulk flow to transit super-Alfvénic sub-Alfvénic exterior interior side cusp. The ATL observed during northward interplanetary magnetic field orien...

Particle verbs (e.g., look up) are lexical items for which particle and verb share a single lexical entry. Using event-related brain potentials, we examined working memory and long-term memory involvement in particle-verb processing. Dutch participants read sentences with head verbs that allow zero, two, or more than five particles to occur downstream. Additionally, sentences were presented for...

Abstract In this paper, a Taylor cone model in the nanoscale is configured using many-body dissipative particle dynamics method. The sharpening process of and breakup at different electric field intensities charge concentrations are systematically investigated. Under strong field, hemispherical droplet sharpened over time evolves into conic one. Then cusp emits thin jet. Finally, shrinks semi-s...

Abstract Auroral whistler‐mode radio emissions called saucers are of fundamental interest because they require an unusually stationary emission process in the dynamic auroral environment, and it is a mystery how that can happen this or similar conditions elsewhere geospace. The Cusp Alfvén Plasma Electrodynamics Rocket (CAPER‐2), launched into cusp, obtained first rocket measurements large‐scal...
