Radiation Process in Relativistic MHD Waves: The Case of Circularly Polarized Alfvén Waves

open access: yesThe Astrophysical Journal
Turbulence in highly magnetized plasma can be relativistic and induce an electric field comparable to the background magnetic field. Such a strong electric field can affect the emission process of nonthermal electrons.

Bremsstrahlung Energy Losses for Cosmic Ray Electrons and Positrons [PDF]

open access: yesarXiv, 2015
Recently cosmic ray electrons and positrons, i.e. cosmic ray charged leptons, have been observed. To understand the distances from our solar system to the sources of such lepton cosmic rays, it is important to understand energy losses from cosmic electrodynamic fields.

Volume measurement of microparticles using SEM photogrammetry and 3‐D reconstruction

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract In this paper, we introduce a method for volume measurement of microparticles that includes scanning electron microscope photogrammetry with 3‐D model construction. Our results show that our method limits the volume uncertainty to ±10%, which is a significant improvement compared to previous methods (which likely overestimated volume by 100 ...

Converging ontologies: On some similarities between the Sāṃkhyakārikā and Plotinus's Enneads

open access: yesMetaphilosophy, EarlyView.
Abstract This article endeavors to conduct a comparative analysis between the philosophical systems of Plotinus and classical Sāṃkhya, two distinct philosophical traditions characterized by their substantial historical and cultural contexts. The primary aim of the study is to discern and evaluate the fundamental themes inherent in these philosophical ...
