Enhancement of Femtosecond Photon Echo Signals From an Inhomogeneously Broadened InAs Quantum Dot Ensemble Using Chirped Pulses. [PDF]
NanophotonicsChirped rephasing pulses satisfying adiabatic conditions enable robust adiabatic rapid passage across a THz‐broadened InAs quantum dot ensemble. This approach provides uniform population inversion and broadband rephasing, overcoming the limitations of transform‐limited excitation.

Alignment and study of prototypes of the Offner hyperspectrometer
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2016 A prototype of the hyperspectrometer based on the Offner scheme has been tested. Drawings have been produced and the main mirror elements of the hyperspectrometer including diffraction grating on a convex spherical surface have been fabricated.

Modeling action of a hyperspectrometer based on the offner scheme within geometric optics
Computer Optics, 2014 We considered comparative modeling action of a hyperspectrometer based on the Offner scheme including prisms or a diffraction grating within the geometrical optics. It is shown that the use of a diffraction grating instead of a prism results in a more uniform spread of the spectral components of the dispersed image.

Collection of selected papers of the II International Conference on Information Technology and Nanotechnology, 2016 We deal with the imaging spectrometer based on the Offner scheme. We define the optical transfer function of the imaging spectrometer based on the Offner scheme. We define the spectrum reconstruction error for red LED.

Spectral‐Resolved Light at Night: TEMPO Observations and Background Correction
Earth and Space Science, Volume 13, Issue 6, June 2026.Abstract Artificial Light at Night (ALAN) poses risks to public health and ecosystems. While long‐term remote sensing has tracked global nighttime light, spectrally resolved light at night (spectral light at night (SLAN)) data from geostationary orbit only became available with NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission. Its

Media Sentiment and Price Run‐Ups
European Financial Management, Volume 32, Issue 2, Page 677-700, March 2026.ABSTRACT We empirically test competing hypotheses about the role of financial media sentiment in price run‐ups. Our global analysis of unusual price increases in stock market segments provides no evidence for long‐term market overreactions fuelled by media reporting.

Algorithm Theoretical Basis for Version 3 TEMPO Level 0–1 Processor
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument is the first spaceborne hyperspectral spectrometer that measures backscattered sunlight over North America in a geostationary orbit. The two charge‐coupled device (CCD) detectors of TEMPO, with spectral coverages of 293–494 and 538–741 nm and resolutions of 0.53–0.63 nm ...
