DMFT, dmft and treatment requirements of schoolchildren in Asturias, Spain

Community Dentistry and Oral Epidemiology, 1998
Abstract –An epidemiological survey was carried out in 1992 to study the dental health status of schoolchildren aged 6, 9 and 12 in Asturias, Spain. It focused on the caries prevalence, dmtf, DMFT, restoration indices and dental treatment needs of this population.

A DFT + DMFT approach for nanosystems

Journal of Physics: Condensed Matter, 2010
We propose a combined density-functional-theory-dynamical-mean-field-theory (DFT + DMFT) approach for reliable inclusion of electron-electron correlation effects in nanosystems. Compared with the widely used DFT + U approach, this method has several advantages, the most important of which is that it takes into account dynamical correlation effects. The

DMFT Impurity Solvers

2021
We describe different impurity solvers used in DMFT. Namely, we show details for three most popular types of solvers: analytical, exact (Hamiltonian-based), and stochastic (quantum–Monte Carlo-based) solvers. Since continuous-time quantum Monte Carlo is the current state-of-art approach to solve the impurity problem, we discuss in detail this and its ...

The Change of DMFT Counts in Slovenia

Caries Research, 2001
This longitudinal study was designed to assess the change in caries prevalence and DMFT counts in the adult population of Ljubljana, Slovenia, over a 10–year period. All data in the present study are derived from two surveys conducted in 1983–1987 and 1993–1997. In the first survey, 1,609 dentate subjects in the range from 15 to 65 years were examined.

Relationship between the care index and mean dmft/DMFT.

Community dental health, 1998
To assess the relationship between the care index and the mean dmft/DMFT in different populations of 5-, 12- and 14-year old children.Information from recent studies of 5-, 12- and 14-year old children, co-ordinated by the British Association for the Study of Community Dentistry (BASCD) was used.

Diagrammatic methods beyond DMFT

2014
Das Verstaendnis von elektronischen Korrelationsphaenomenen stellt eine der groe ten Her- ausforderungen der Festkoerperphysik dar. In den letzten 25 Jahren hat sich die dynamische Molekularfeldtheorie (DMFT) als die "Standardmethode" fuer korrelierte fermionische Systeme etabliert, welche weit ueber eine stoerungstheoretische Behandlung hinausgeht ...

Obezite ile Çürük, Kayıp, Dolgulu Dişler (DMFT/dmft) İndeksi Arasındaki İlişki

2020
Obezite vücuda alınan enerjiyle harcanan enerji arasındaki dengesizlikten kaynaklanan morbidite ve mortalite oranını önemli ölçüde arttırtan kronik bir hastalıktır. Obezite prevalansı dünyada olduğu gibi ülkemizde de hızla artmaktadır. Obezite kardiyovasküler hastalıklar, diyabet, hipertansiyon, kanserler gibi bir dizi hastalıkla ilişkili olup; orta ...

Multi-orbital and Cluster DMFT

2021
In this chapter, we present generalizations of the one-orbital one-atom-cell Hubbard model on the multi-orbital and cluster (several atoms in the unit cell) cases. We begin with derivation of the DMFT equations in the multi-orbital case and proceed with the cluster DMFT.
