Density-Functional Theory+Dynamical Mean-Field Theory Study of the Magnetic Properties of Transition-Metal Nanostructures
… Theory (DFT) and Dynamical Mean-Field Theory (DMFT) approaches are applied to study the magnetic properties of transition metal nanosystems of different sizes and compositions. In particular, in order to take into account dynamical electron correlation effects (time-resolved local charge …

The Study of Transition Metal Oxides using Dynamical Mean Field Theory
… in bulk systems. Dynamical mean-field theory (DMFT) emerges as a successful numerical method to treat the strong correlation. The combination of density functional and dynamical mean-field theory (DFT+DMFT) is a prospective ab initio approach for studying realistic strongly correlated …

Inrteraction between the oral health index and the quality of life related to oral health of North Korean defectors
… Korea over the age of 20 staying in Hanawon. DMFT index and CPITN(Community Periodontal Index Treatment Needs) were selected as indicators of oral health and OHIP-14K(Oral health impact profile-14 Korea version) was employed to survey quality of life related to oral health. ANALYSIS: The …

The Impact of Oral Health on Quality of Life in the Aging Population
… two free response (QoL) questions, OHI-S, and DMFT indices to collect data. Results: Spearman’s rank coefficient analyzed correlations between OHI-S, DMFT, and OIDP indices and found a significant relationship between the OHI-S and OIDP (p=0.036) implying oral disease from plaque and calculus …

Anistropic phenomena in strongly correlated electron systems
… two-site cluster dynamical mean field theory (DMFT), at zero temperature. The "two-site" approach provides a drastically simplified but physically motivated self-consistency scheme for DMFT. This is combined for the first time with cluster DMFT, within which different magnetic orders and …

Prevalence of dental caries and tooth brushing habits among preschool children in Khartoum State, Sudan
… caries of the children was 52.4% with mean dmft of 2.27. There was an increase in the dmft scores with increasing age. The highest brushing frequency was found among the children whose mothers had a postgraduate degree and the lowest proportion was from uneducated mothers. Eating …

Rapid Detection of <em>Streptococcus mutans</em> in Saliva
… received 2 bitewing x-rays and a charted DMFT index and were administered the saliva test. While the null hypothesis was rejected using the chi square test, the results were inconclusive due to expected values. However, other chi square results revealed that the test worked or had the …

Electronic correlations in Lix̳ CoO₂
… (DFT) and the dynamical mean-field theory (DMFT). Three main problems are addressed. First, the influence of hybridization among the eg and oxygen orbitals is studied using DFT and a modified Hubbard model which is solved within DMFT. It has long been known that doping holes into the t2g …
