Fast algorithms for Brownian dynamics simulation with hydrodynamic interactions
… we first present two fast multipole methods (FMM) for computing Du. The first FMM is a simple application of the kernel independent FMM (KIFMM) developed by Ying, Biros, and Zorin [3], which requires 9 scalar FMM calls. The second FMM, similar to the FMM for Stokeslet developed by Tornberg and …

Two Novel Fast Algorithms for Analysis of Low-Frequency Transient Electromagnetic Phenomena
… TDIE solver that is augmented by the LF-TD-FMM algorithm and uses loop-patch basis functions and integral/differential form of TDIE to improve its efficiency and stability. This fast solver can be used for full-wave analysis of high-speed electronic circuits.

A Study of Techniques to Solve the Disparate Mesh Size Problem With an Application to Sinuous Antennas
… when trying to apply the fast multipole method (FMM) to a particular wideband antenna, the sinuous antenna. The essence of the problem is that a triangular patch mesh containing a wide range in patch sizes produces an ill-conditioned method of moments impedance matrix. Since the FMM algorithm …

Application of Hidden Markov Model in Finite Mixture Modeling of High-Dimensional Data
Finite mixture models (FMMs) are widely used in practice and are famous for modeling heterogeneous data in a convenient and effective way. Owing to their flexibility, finitemixtures have since been applied to a wide range of problems in diverse fields, includingimage analysis, medicine, …

New ways to tune the multi-functionality of oxide thin films for memory applications
… the ferromagnetic insulating (FMI) and metallic (FMM) properties of La0.9Ba0.1MnO3 (LBMO) are tuned using VAN. La0.9Ba0.1MnO3 is FMI in bulk but usually shows metallicity in plain films. By using VAN consisting of CeO2 nanocolumns embedded in a La0.9Ba0.1MnO3 matrix, the FMI property is maintained …

Floodplain Resource Management: An Economic Analysis of *Policy Issues in Bangladesh
… poor. We develop a floodplain management model (FMM) where net returns to agriculture and fisheries are jointly maximized. The model accounts explicitly for the effect of floodplain area on fisheries production, where productivity is a function of the flood land type. These are derived from …

Fast algorithms for small particle scattering problems
… complexity is the fast multipole method (FMM). This is based on the factorization of the Green's function and is useful only in those cases where the Green's function of the system can be decomposed into a product of special functions. The decomposition of the free space Green's function …

Linear scaling density functional theory with Gaussian orbitals and periodic boundary conditions
… based on the direct space fast multipole method (FMM). The FMM achieves not only linear scaling of computational time with system size but also high accuracy, which is pivotal for avoiding numerical instabilities that have previously plagued calculations with large bases, especially those …

Impact of a newly designed food complement (food multimix) on nutritional status and birth outcomes of pregnant women in the Gauteng province of South Africa
… = 18 weeks) assigned to intervention (100 g/d FMM soup + daily diet) or control (100 g/d local commercially sold soup + daily diet, placebo) group from enrolment to term (average, 20 weeks of feeding). Maternal energy uptake increased from 6.67 MJ/day (66% of DRI) to 7.96 MJ (79% of DRI) in the …

Social organization during mating, but not offspring care, influences the reproductive success of male degus, Octodon degus
… units containing one female and multiple males (FMM). Spring male social organization did not have an impact on male reproductive success. This suggests certain social organization types are reproductively costly to male degus during the mating season (autumn-winter) but not offspring care …

The proxy point method for rank-structured matrices
… matrices and the fast multipole method (FMM). This equivalence has not been rigorously studied in the literature. Numerical comparisons between FMM and $\mathcal{H}^2$ matrices based on the proxy point method are also provided, showing the relative advantages and disadvantages of the two …

Prenatal influences on fetal neurodevelopment: Can a person-centered approach help parse the complexity of maternal vulnerability and protective features and detect early alterations to fetal neurodevelopment trajectories related to prenatal distress?
… (n = 108 dyads). First, factor mixture modeling (FMM) was used to identify subgroups of pregnant women and characterize phenotypic maternal risk profiles, derived from multiple self-report measures of distress and mood, psychopathology symptoms, pregnancy symptoms, personality, emotion reactivity, …
