Photon-axion conversion in intergalactic magnetic fields and cosmological consequences [PDF]

, 2006
Photon-axion conversion induced by intergalactic magnetic fields causes an apparent dimming of distant sources, notably of cosmic standard candles such as supernovae of type Ia (SNe Ia).

Towards a Fregean psycholinguistics

Analytic Philosophy, Volume 66, Issue 3, Page 349-371, September 2025.
Abstract This paper is partly exegetical, partly systematic. I argue that Frege's account of what he called “colouring” contains some important insights on how communication is related to mental states such as mental images or emotions. I also show that the Fregean perspective is supported by current research in psycholinguistics and that a full ...

Communicating tokenomics and monetary policy: A comparative analysis of real and virtual economies

International Journal of Finance &Economics, Volume 30, Issue 3, Page 2849-2866, July 2025.
Abstract This article investigates the economic governance of blockchain‐based virtual economies in the context of monetary policy. Focusing on tokenomics communication, we employ deductive and inductive approaches, applying real‐world monetary policy metrics and text mining frameworks. Our comparative analysis reveals that the tokenomics communication

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Modeling and Optimization of Infrared‐Convection Drying Parameters and Slice Thickness of Onion Slices: Effects on Drying Kinetics and Physicochemical Quality

Food Science &Nutrition, Volume 13, Issue 6, June 2025.
This assessment focused on drying time, color, shrinkage, water activity, and rehydration ratio. Onion slices were dried using infrared powers 1500, 3500, and 5500 W/m2, airflow rates 0.3, 0.7, and 1.0 m/s, and thicknesses 4, 6, and 8 mm. Midilli and Kucuk most effectively improved the drying process of onion slices in a thin layer.

The Fractal Geometry of the Cosmic Web and Its Formation

Advances in Astronomy, Volume 2019, Issue 1, 2019., 2019
The cosmic web structure is studied with the concepts and methods of fractal geometry, employing the adhesion model of cosmological dynamics as a basic reference. The structures of matter clusters and cosmic voids in cosmological N‐body simulations or the Sloan Digital Sky Survey are elucidated by means of multifractal geometry.

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

Computer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

Plasma‐assisted fabrication of multiscale materials for electrochemical energy conversion and storage

Carbon Energy, Volume 7, Issue 2, February 2025.
In this review, we aim to provide a comprehensive understanding of plasma and its application in energy storage and conversion. The classification of plasma technologies and principles are summarized. Recent developments in the synthesis or modification of multiscale materials based on plasma techniques including conversion, doping, deposition, and ...

Scattered Lyman-alpha Radiation Around Sources Before Cosmological Reionization

, 1999
The spectra of the first galaxies and quasars in the Universe should be strongly absorbed shortward of their rest-frame Lyman-alpha wavelength by neutral hydrogen (HI) in the intervening intergalactic medium. However, the Lyman-alpha line photons emitted

M82 - A radio continuum and polarisation study I. Data reduction and cosmic ray propagation [PDF]

, 2013
The potential role of magnetic fields and cosmic ray propagation for feedback processes in the early Universe can be probed by studies of local starburst counterparts with an equivalent star-formation rate.
