On-Orbit Performance of the GF-7 Satellite Laser Altimetry System from 2020 to 2024
Published 2025-07-01Get full textThe Gaofen-7 (GF-7) satellite represents China's first civil satellite equipped with a full waveform laser altimeter. This study aims to evaluate its on-orbit performance by analyzing the transmitting and receiving systems through the examination of waveform parameter and laser energy. The resu...

Electron Acceleration at Shock Ripples: Role of Pitch-angle Diffusion
Published 2025-01-01Get full textSuprathermal electrons are routinely observed in interplanetary space. At higher energies, there are in-situ evidences that shocks, both interplanetary shocks, often driven by fast coronal mass ejections, and terrestrial bow shocks, can accelerate electrons up to transrelativistic energies (∼MeVs)....

The Importance of Anthropogenic Influence in Assessing the Ecological Condition of Cities in Uzbekistan (in the Case of Navoi)
Published 2024-04-01Get full textCreating a series of maps, grouping ecological indicators, and assessing cities' environmental status are considered very relevant research tasks. A growing population in cities, the establishment of various industrial and production enterprises, and the use of vehicles all contribute to the d...

Comparison of Integrating GF-7 and ICESat-2 Laser Altimetry Data with High-resolution Stereo Images for Stereo Mapping
Published 2025-07-01Get full textCurrently, two types of satellite laser altimetry systems are in operation: the full waveform linear system and the single-photon-counting system, which exhibit significant differences in both data format and processing methodologies. It remains uncertain which satellite laser altimetry technology o...

Magnetopause Location and Solar Wind Turbulence Level During FDs and Their Impacts on the Global Electric Circuit
Published 2025-06-01Get full textAbstract During Forbush decreases (FDs), the fluxes of high‐energy galactic cosmic rays (GCRs) are suppressed. As a consequence, the ionization profile of the atmosphere is affected and the global electric circuit system is perturbed. Recently, using cosmic ray measurements from the Alpha Magnetic S...

Comparative analysis of protocols for decellularization of corneal lenticular tissue
Published 2021-07-01Get full textShortage of donor corneas is a burning issue in ophthalmology. That is why there is a search for new alternative ways for treating corneal diseases. Decellularization technologies make it possible to create corneal tissue-engineered constructs that can adrress the issue of donor corneal shortage. Ob...

Source-explicit estimation of brown carbon in the polluted atmosphere over the North China Plain: implications for distribution, absorption, and the direct radiative effect
Published 2025-07-01Get full text<p>Brown carbon (BrC) plays a significant role in altering atmospheric radiation. Beyond biomass and biofuel combustion, recent studies identify fossil fuel sources – especially residential coal burning and vehicle exhaust – as major contributors to BrC. This underscores a gap in climate model...

Inaugural central fueling experiment with Compact Torus in EAST
Published 2025-01-01Get full textWe report, for the first time, non-disruptive central fueling experiments utilizing Compact Torus (CT) plasma injection in the medium-sized fully-superconducting tokamak, EAST ( R _0 = 1.9 m, a = 0.45 m, B _t = 1.5–2.5 T). In these experiments, the CT plasma achieved velocities near 150 km s ^−1 , w...
