BACKGROUND This study was carried out as a prospective clinical field study with the aim of evaluating the clinical performance of Equia Fil® with a nanofilled resin coating and the conventional Fuji IX GP® fast with an LC coating according to the World Dental Federation (FDI) restoration material evaluation criteria. METHODS The clinical performance of Equia Fil® and Fuji IX GP® fast was eva...

We prove an explicit, quantitative criterion that ensures the Heegaard surfaces in Dehn fillings behave “as expected.” Given a cusped hyperbolic 3-manifold X, and a Dehn filling whose meridian and longitude curves are longer than 2π(2g − 1), we show that every genus g Heegaard splitting of the filled manifold is isotopic to a splitting of the original manifold X. The analogous statement holds f...

We exhibit a weight-preserving bijection between semi-standard Young tableaux and skyline augmented fillings to provide the first combinatorial proof that the Schur functions decompose into nonsymmetric functions indexed by compositions. The insertion procedure involved in the proof leads to an analogue of the Robinson-SchenstedKnuth Algorithm for skyline augmented fillings. We also prove that ...

We study the coexistent state of the spin density wave (SDW) and the charge density wave (CDW) in a one-dimensional extended Hubbard model. We find that the coexistent state of SDW and CDW is stabilized in various electron-filling cases when band parameters are for organic conductors. The ground state energies have cusp-like minima at n/4m-fillings, where n and m are integers. The maxima of the...

introduction: sealing ability is an important factor for a root-end filling material in endodontic surgeries. this in vitro study aimed to compare the sealing ability of mineral trioxide aggregate (mta) and a new endodontic cement named calcium enriched mixture (cem) cement as root-end filling materials. materials and methods: the experiments were carried out in dry, saliva or blood contaminate...
