Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, Volume 19, Issue 21, November 6, 2025.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Analyzing SEU Rate in LEO Satellites During the Space Weather Event of May 2024

open access: yesSpace Weather, Volume 23, Issue 11, November 2025.
Abstract From 10 to 12 May 2024, Earth experienced the most intense geomagnetic storm in two decades. Using observational data from the Fengyun‐3E satellite (FY‐3E) and the empirical formula for single event upset (SEU), we investigate the proton flux distribution in both the South Atlantic Anomaly (SAA) and high‐latitude regions, as well as the ...

Current State of Accountants' Knowledge of Digital Technologies: Evidence From Australia and New Zealand

open access: yesAccounting &Finance, Volume 65, Issue 3, Page 2649-2664, September 2025.
ABSTRACT Using survey research, we investigate accountants' self‐rated knowledge of a variety of digital technologies (DTs). We find that accountants' self‐rated knowledge of established DTs is almost in line with IES2 requirements, but their self‐rated knowledge of emerging DTs is significantly below IES2 requirements. Of greater concern, we find that

On the possibility of determining the parameters of the ionosphere when removing a nanosatellite from orbit using an uninsulated conductive tether

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
Currently, one of the ways to quickly remove spent nanosatellites from orbit is the use of non-insulated conductive tether, during the movement of which an electrodynamic braking force arises in the Earth's magnetic field, transferring the nanosatellite ...

Compression‐Expansion: Miniaturization, Modularity, and Logistics Beyond Earth

open access: yesAmerican Anthropologist, Volume 127, Issue 3, Page 424-434, September 2025.
ABSTRACT If the Cold War space race culminated in a return to Earth, at present we are experiencing a renewed interest in space. Drawing on fieldwork among people working in the space sector in Sweden, this article focuses on some of the imaginaries underpinning this resurgence and the contemporary commercialization of space. Specifically, I hone in on

High‐fundamental‐mode output of 1064 nm vertical‐cavity surface‐emitting laser using double embedded antiresonant oxide islands

open access: yesInformation &Functional Materials, Volume 2, Issue 2, Page 118-129, June 2025.
A two‐junction 1064 nm VCSEL with double antiresonant oxide islands in the top DBR is designed to enhance fundamental transverse mode operation. By optimizing island count, aperture size, thickness, and position, it achieves 36.2 mW output power, 54.8% PCE, and a 33.06 GHz 3 dB bandwidth.

Анализ движения наноспутника SamSat-218Д по траекторным измерениям

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2019
Анализируется движение наноспутника SamSat-218Д по траекторным измерениям. Экспериментально подтверждены особенности поведения наноспутников на низких орбитах, обусловленные как влиянием атмосферы, так и присущими им массово-инерционными характеристиками:
