Governance of Long‐Term Scientific Infrastructure: Public Value Does Not Protect Itself

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Long‐term scientific infrastructure, including physical archives, monitoring networks, and place‐based research facilities, is frequently described as important but is rarely protected by enforceable governance. When administrative reorganization or budget pressure threatens such infrastructure, the scientific community typically responds with

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Thermal Behavior of Radiative Darcy–Forchheimer Nanofluid Flow With Heat Source/Sink Effects

Engineering Reports, Volume 8, Issue 9, September 2026.
Radiative Darcy–Forchheimer nanofluid flow in a porous medium is numerically analyzed with heat source/sink effects. Radiation enhances heat transfer and boundary layer thickness, while increasing Forchheimer resistance suppresses velocity, providing insights for optimizing thermal management in high‐temperature porous systems.

Thin‐film lithium niobate photonics: Frontiers in millimeter‐wave and terahertz generation and integrated applications

InfoScience, Volume 3, Issue 3, September 2026.
With the advancement of 6G communications, high‐precision radar, and advanced imaging technologies, there is a growing demand for compact, high‐performance light sources capable of generating high‐frequency radio waves (millimeter‐wave and terahertz waves). This article systematically introduces how to efficiently generate these high‐frequency waves on
