A new approach to the maser emission in the solar corona [PDF]
, 2015 Aims. The electron plasma frequency ωpe and electron gyrofrequency Ωe are two parameters that allow us to describe the properties of a plasma and to constrain the physical phenomena at play, for instance, whether a maser instability develops.

Charge transport mechanisms in corona charged polymeric materials
, 2013 Polymeric materials have been widely used as an insulator due to their excellent electrical properties, light weight and low cost. Surface potential measurement is one of the simplest and low cost tools to gauge electrical properties of materials.

Exact Solutions for the Moving Firefighter Problem on Trees
Networks, Volume 88, Issue 1, Page 42-58, July 2026.ABSTRACT The moving firefighter problem (MFP) is a more realistic variant of the classic firefighter problem (FP), where firefighters require time for both travel and defense. Unfortunately, the only known exact solution for the MFP does not scale. In this paper, we establish that the MFP is NP‐complete on trees of maximum degree three and present four

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Lava tubes and caves are key exploration targets on the Moon and Mars due to their potential to serve as natural infrastructure for future crewed missions. However, identifying these structures efficiently and reliably remains a major challenge.

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3536-3549, June 2026.ABSTRACT Purpose First‐pass perfusion cardiovascular MR (FPP‐CMR) enables the non‐invasive diagnosis of microcirculation and coronary artery disease. In free‐breathing FPP‐CMR, motion correction is usually performed in the image domain, requiring an initial reconstruction.
