Journal of Geophysical Research: Space Physics, Volume 130, Issue 10, October 2025.Abstract We use Particle‐In‐Cell (PIC) simulations to investigate the charging characteristics inside deep cavities on the lunar surface under the solar wind plasma conditions. Specifically, we systematically study the dependence of the cavity bottom potential on plasma flow velocity and cavity aspect ratio.

Mathematical Problems in Engineering, Volume 2010, Issue 1, 2010., 2010 This paper introduces a new parallel algorithm based on the Gram‐Schmidt orthogonalization method. This parallel algorithm can find almost exact solutions of tridiagonal linear systems of equations in an efficient way. The system of equations is partitioned proportional to number of processors, and each partition is solved by a processor with a minimum

Audio description for all? The benefits and concerns of extending access provision to sighted people
Curator: The Museum Journal, Volume 68, Issue 2, Page 387-403, April 2025.Abstract Audio description (AD) is an established part of museums' access programs for blind and partially blind (BPB) people. This paper explores the merits and caveats regarding “AD for all”, rolling out the provision for sighted people as well.

VLSI Design, Volume 10, Issue 4, Page 437-452, 2000., 2000 We present a 3D Ensemble Monte Carlo particle‐based simulator with a novel realspace treatment of the short‐range electron – electron and electron‐ion interactions. By using a corrected Coulomb force in conjunction with a proper cutoff range, the shortrange portion of the force is properly accounted for, and the ‘double counting’ of the long‐range ...

Reconsidering the black hole final state in Dirac fields
, 2005 We extend Horowitz and Maldacena's proposal about black hole final state to Dirac fields and find that if annihilation of the infalling positrons and the collapsed electrons inside the horizon is considered, then the nonlinear evolution of collapsing ...

Amino acid sequence encodes protein abundance shaped by protein stability at reduced synthesis cost
Protein Science, Volume 34, Issue 1, January 2025.Abstract Understanding what drives protein abundance is essential to biology, medicine, and biotechnology. Driven by evolutionary selection, an amino acid sequence is tailored to meet the required abundance of a proteome, underscoring the intricate relationship between sequence and functional demand.
