A mobile W-DIMM device was used to measure seeing at the Crimean station of SternbergAstronomical Institute of Moscow State University over seven nights, from June 23 to 30, 2024. Seeingestimates for altitudes greater than 500 m were inferred from scintillations in the sensor apertures separate from the total optical turbulence power. The zenith-adjusted seeing values were βmed ≈ 1.15", the corresponding seeing for the upper atmosphere was found to be of about 0.28". A comparison of the seeing estimates obtained on these nights at telescopes with long exposures agrees well with the readings of the mobile differential image motion monitor. Some climatic parameters were also obtained both from astationary weather station near the observation point and from satellite data.

Numerous studies have provided compelling evidence that the probability distribution of avalanche sizes follows a power law, and that 1/f noise is present in the stochastic dynamics of landslides. We present a theoretical explanation of these phenomena within the framework of self-organized criticality theory, proposing a discrete-time model in the form of a sandpile cellular ...

A discrete-time model is presented for the self-organization of the X/Twitter social network to the edge of a phase transition, characterized by avalanche-like propagation of information in the network. The model is based on the analogy between the critical dynamics of the X social network and sandpile cellular automata with Manna rule on the Chung-Lu ...

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

Machine learning (ML) has become a powerful tool for accelerating the development of carbon-based supercapacitors;
however, most published models assume that a single predictive framework can describe both conventional
porous carbons and hybrid carbon electrodes. Here, we test this assumption using a comprehensive
benchmark dataset and an extended literature-curated dataset enriched with synthesis- and electrolyte-related
descriptors. Three ML algorithms ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...

Manufacturing precise quantum computers with small errors in quantum operations, long coherence times, and low power consumption is the most important challenge in modern nanoelectronics. To understand the operating modes of such calculators in detail, both the optimal arrangement of the qubit system within the structure and changes in its magnetic properties must be comprehensively ...

The article is devoted to the study of media images of small celestial bodies – comets, asteroids and meteorites. Special attention is paid to the "impact" representation of these space objects, which reflects their probable or occurred collision with the Earth. The article answers a number of questions: since when, in what contexts and images ...

Proceeding from a fragment of Vasily Rozanov about astronomy, Auguste Comte and horoscopes, our study clarifies the complex ideological relationship between astronomy and astrology in intellectual culture of the turn of the XIX – XX centuries. Both these disciplines were closely related with positivism: the main goal of science— the search for scientific laws — was identified as a ...

The number of space objects will grow several times in a few years due to the planned launches of constellations of thousands microsatellites. It leads to a significant increase in the threat of satellite collisions. Spacecraft must undertake collision avoidance maneuvers to mitigate the risk. According to publicly available information, conjunction events are now manually ...

Optical and near-infrared photometry, optical spectroscopy, and soft X-ray and UV monitoring of the changing-look active galactic nucleus NGC 2617 show that it continues to have the appearance of a type-1 Seyfert galaxy. An optical light curve for 2010-2016 indicates that the change of type probably occurred between 2010 October and 2012 February and was ...
