An overview of fast multipole methods [PDF]
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 ...

Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes
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.

Combining the multilevel fast multipole method with the uniform geometrical theory of diffraction [PDF]
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).

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

A Cubed Sphere Fast Multipole Method
This work describes a new version of the Fast Multipole Method for summing pairwise particle interactions that arise from discretizing integral transforms and convolutions on the sphere. The kernel approximations use barycentric Lagrange interpolation on a quadtree composed of cubed sphere grid cells.

The vortical differential scattering of spatiotemporal optical vortices by chiral particles is investigated. It is revealed that a longitudinal orbital angular momentum component is essential for inducing vortical dichroism, whereas a purely transverse OAM yields no chiral response.

Generalized fast multipole method
The fast multipole method (FMM) is a technique allowing the fast calculation of long-range interactions between N points in O(N) or O(N ln N) steps with some prescribed error tolerance. The FMM has found many applications in the field of integral equations and boundary element methods, in particular by accelerating the solution of dense linear systems ...
