Fast computation of electromagnetic near-fields with the multilevel fast multipole method combining near-field and far-field translations [PDF]
Advances in Radio Science, 2006 In Electromagnetic Compatibility (EMC) problems, computation of electromagnetic near-fields in the vicinity of complex radiation and scattering systems is often required. Numerical solution of such problems is achieved using Boundary Integral (BI) based

Ion Activation Methods for Top‐Down Proteomics
Mass Spectrometry Reviews, EarlyView.ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
Mass Spectrometry Reviews, EarlyView.ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

An error-controlled fast multipole method [PDF]
The Journal of Chemical Physics, 2009 We present a two-stage error estimation scheme for the fast multipole method (FMM). This scheme can be applied to any particle system. It incorporates homogeneous as well as inhomogeneous distributions. The FMM error as a consequence of the finite representation of the multipole expansions and the operator error is correlated with an absolute or ...

Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes
The FEBS Journal, EarlyView.Cold‐active enzymes retain high catalytic activity at low temperatures but are characterized by thermal instability, a behavior not fully understood. Comparison between a cold‐active GH1 and its mesophilic counterparts highlights the role of a three‐residue motif (W‐M‐F) in conferring structural stability to a mesophilic GH1.

Nanophotonics, Volume 15, Issue 13, 13 July 2026.Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...

An overview of fast multipole methods [PDF]
, 1995 A number of physics problems may be cast in terms of Hilbert-Schmidt integral equations. In many cases, the integrals tend to be zero over a large portion of the domain of interest. All of the information is contained in compact regions of the domain which renders their use very attractive from the standpoint of efficient numerical computation ...

Combining the multilevel fast multipole method with the uniform geometrical theory of diffraction [PDF]
Advances in Radio Science, 2005 The presence of arbitrarily shaped and electrically large objects in the same environment leads to hybridization of the Method of Moments (MoM) with the Uniform Geometrical Theory of Diffraction (UTD).

Dramatic and Elusive Resonant Lattice Kerker Effect in the Nonlinear Response of Plasmonic Lattices
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Plasmonic metasurface that supports the resonant lattice Kerker effect, manifesting as the suppression of reflection in a narrow spectral range due to the simultaneous excitation of electric dipole and quadrupole modes, also gives rise to a substantial near‐field enhancement.
