Fabrication and Characterization of X-ray TES Detectors Based on Annular AlMn Alloy Films. Yifei Zhang et. al. https://arxiv.org/abs/2510.00642
A side view of a TES detector. The gold absorber is square (240 $ $m x 240 $ $m) with a thickness of 2.7 $ $m. It is elevated about 2.5 $ $m from the substrate by five 10 $ $m-width square stems. The center stem doubles as a thermal link to the AlMn TES. Figure 2 TES detector test system and internal physical diagram. (a) depicts the structure of the whole test bench, including a $^{55 Figure 4

Machine Learning-Ready Data Sets for the Analysis and Nowcasting of Atmospheric Radiation at Aviation Altitudes. Viacheslav M Sadykov et. al. https://arxiv.org/abs/2602.07108
Evolution of some selected Geospace environment parameters from June 2013 until December 2024, from top to bottom: daily sunspot number, neutron monitor corrected counts from four stations considered, integrated soft X-ray fluxes, energetic proton fluxes, geomagnetic indexes (Kp and Dst), and sol... (a) Schematic structure of the ML-ready dataset entity. A target corresponds to the measurement of radiation dose rate during the ARMAS flight, and the feature vector represents the flight timing and coordinates, NAIRAS predictions, and prehistory of the measurements of the environment. (b) Illus... Coverage of considered ARMAS flight measurements over the Earth globe. The individual measurements are marked as orange points on the map. Left: Measured radiation dose rates VS predicted using an ML model (Random Forest Regressor). The ML model was trained on partition 1 of the static dataset and evaluated on partition 2. Right: Measured radiation dose rates VS nowcast of a physics-based NAIRAS~V3 model for partition 2.

Variation of the sunspot area during the rising and declining phases of the solar cycle supports the toroidal flux loss due to flux emergence. Bidya Binay Karak et. al. https://arxiv.org/abs/2602.07194
The mean of the absolute latitudes of sunspot groups in each year ($ $) verses the number of sunspot groups in that year. Different curves are for different cycles. One year data at the beginning and at the end of each cycle are excluded in this analysis. Note that a cycle begins with a high valu...
