Summary: Atmospheric escape on Mars and its relationship with the ionosphere is a critical factor in understanding the loss of habitability. Solar extreme ultraviolet radiation is the main driver of variations in the Martian ionosphere. While the response of ionospheric electrons to this radiation has been well studied, the responses of different ion species are not yet fully understood. This study presents direct observations of periodic variations in photoelectrons and ions, with a common period of approximately 27.2 days and in phase with solar rotation. These variations show significantly different amplitudes, with ion density having a larger amplitude than solar flux and electron density having a smaller amplitude. The species-dependent solar rotation effects provide insights into the upper atmospheric and ionospheric chemistry, highlighting the need to reconsider the composition and variability of any planetary ionosphere driven by solar activity.

Summary: This study presents direct observations of the thermospheric density responses to three solar eclipses, showing density depletions and large-scale traveling atmospheric disturbances (TADs). While the observed responses generally agree with simulations from the TIEGCM model, there are differences in the recovery rates between the simulations and observations, providing insights into the mechanism of eclipse effects on the ionosphere-thermosphere system.

Summary: Recent research has found that aside from the traditional view of planet collisions, the accumulation of pebbles can also explain the mass-orbit distribution of terrestrial planets. However, N-body simulations show that pebble accretion played little or no role in the formation of planetary systems in the inner Solar system.

Summary: This study proposes a new platform for desalination and salinity gradient power generation using solar energy. The calcium alginate hydrogel can reduce the energy required for water evaporation and convert the salinity gradient into electrical energy. This method has the potential for combining desalination and power generation, demonstrating the prospects for diversified use of blue energy.

Summary: This study demonstrates the fabrication of ultrathin FPSCs using a flip-over transferring process on parylene-C substrates. The use of an ITGZO film as the bottom transparent electrode leads to a remarkable PCE of 20.2%, comparable to that of common FPSCs. The research highlights the great potential of parylene-C films in the fabrication of efficient, ultrathin, and ultralight solar cells.

Summary: Grid-connected photovoltaic systems face challenges like voltage fluctuations, low system inertia, and power quality issues, which require the adoption of flexible power point tracking to control PV power output. The secant method algorithm proposed in this article shows significantly improved results in terms of fast transient response, reduced oscillation around the set-point, and faster convergence.

Summary: The research introduces a two-stage solar power forecasting algorithm that utilizes solar irradiation observations from various locations to make predictions. It first predicts solar irradiation based on numerical weather prediction and then forecasts solar power based on the predicted irradiation. By addressing probabilistic forecasting issues, the model accuracy is enhanced.

Summary: Solar power satellites are receiving great attention for their potential to address future energy crises and environmental problems. This study proposes a novel quasi-Sun-pointing attitude in a Sun-frozen orbit to reduce mass and fuel consumption. The influences of system parameters and structural flexibilities are investigated, and simulation results demonstrate that the quasi-Sun-pointing attitude can significantly reduce fuel consumption, dry mass, and control system complexity.

Summary: This paper discusses the origin of small parameters and aims to explain the Hierarchy problem. Flexible extra dimensions play a crucial role in the formation of physical parameters. The evolution of multidimensional metric starts from the Planck scale and ends with a static extra-dimensional metric and a 4-dimensional de Sitter space at high energies, leading to exponentially produced causally disconnected universes. Quantum fluctuations independently distort the metric within these universes, causing inflationary processes. Some universes asymptotically tend towards states characterized by small Hubble parameters. The explanation for the effective parameter reduction in the Higgs sector of the Standard Model lies in the presence of small-amplitude distributions of a scalar field in a fraction of these universes.
