The Newtonian potential of thin disks [PDF]
The one-dimensional, ordinary differential equation (ODE) by Hur\'e & Hersant (2007) that satisfies the midplane gravitational potential of truncated, flat power-law disks is extended to the whole physical space.

Defect free global minima in Thomson's problem of charges on a sphere [PDF]
Given $N$ unit points charges on the surface of a unit conducting sphere, what configuration of charges minimizes the Coulombic energy $\sum_{i>j=1}^N 1/r_{ij}$?

A New Parallel N-body Gravity Solver: TPM [PDF]
We have developed a gravity solver based on combining the well developed Particle-Mesh (PM) method and TREE methods. It is designed for and has been implemented on parallel computer architectures.

Between a Rock and a Blue Chair: David Hockney’s Rocky Mountains and Tired Indians (1965)
Travel and cultural exchange between the United Kingdom and the United States of America became a key feature of the 1960s, shaping the world view of many a British artist, curator, architect, writer, film-maker, and academic. Against that wider backdrop,

A Bigger Splash to the Narrative
The objective of this article is to offer an example of a work of art identified with what Paul Ricœur named polysemy or linguistic density. Some works of art exemplify a metaphoricity in their constitution and the metaphor would be a privileged model ...

Using Perturbative Least Action to Recover Cosmological Initial Conditions [PDF]
We introduce a new method for generating initial conditions consistent with highly nonlinear observations of density and velocity fields. Using a variant of the Least Action method, called Perturbative Least Action (PLA), we show that it is possible to ...

Solar Wind Ion Entry Into the Magnetosphere During Northward IMF
Abstract Extended periods of northward interplanetary magnetic field (IMF) lead to the formation of a cold, dense plasma sheet due to the entry of solar wind plasma into the magnetosphere. Identifying the paths that the solar wind takes to enter the magnetosphere, and their relative importance has remained elusive.

Efficient and accurate three dimensional Poisson solver for surface problems
We present a method that gives highly accurate electrostatic potentials for systems where we have periodic boundary conditions in two spatial directions but free boundary conditions in the third direction.

Moduli space of Chaudhuri-Hockney-Lykken strings [PDF]
We discuss an orbifold of the toroidally compactified heterotic string which gives a global reduction of the dimension of the moduli space while preserving the supersymmetry. This construction yields the moduli space of the first of a series of reduced rank theories with maximal supersymmetry discovered recently by Chaudhuri, Hockney, and Lykken.
