Large Language Models for Software Engineering: Survey and Open Problems

This paper provides a survey of the emerging area of Large Language Models (LLMs) for Software Engineering (SE). It also sets out open research challenges for the application of LLMs to technical problems faced by software engineers. LLMs' emergent properties bring novelty and creativity with applications right across the spectrum of Software Engineering activities including coding, design, requirements, repair, refactoring, performance improvement, documentation and analytics. However, these very same emergent properties also pose significant technical challenges; we need techniques that can reliably weed out incorrect solutions, such as hallucinations. Our survey reveals the pivotal role that hybrid techniques (traditional SE plus LLMs) have to play in the development and deployment of reliable, efficient and effective LLM-based SE

Advanced theoretical and experimental material on the use of various designs of the devices of the pressurization gas input in the carrier rocket fuel tanks has been analyzed and summarized. Major problems of designing these devices are formulated regarding the high-temperature (generator) gas pressurization. First, it is the gas pressure undershoot in a tank at the carrier rocket start time, as well as overheating of the upper bottom of the tank by the end of the power plant operation. Certain simple designs solving the issues in the most typical cases are described. Taking into account the obtained results, the classification of the gas input devices in the fuel tanks of the carrier rocket power plants has been further developed. It provides designers with the greatest insight possible to the capabilities and special features of the gas input into the tanks. The further ways of improving these devices are already outlined. The devices suggested in the classification make one optimistic about the prospect of using of a generator gas at even higher temperatures up to 1500–1800 K.Аннотация.

Third contribution on Rovno amber silken fungus beetles: a new Eocene species of Cryptophagus (Coleoptera, Clavicornia, Cryptophagidae)

Cryptophagus alexagrestis Lyubarsky & Perkovsky sp.n. is described based on a fossil inclusion in Late Eocene Rovno amber (Ukraine). The new species is similar to the extant Cryptophagus skalitzkyi Reitter and C. dilutus Reitter, differing from the latter bya very transverse, short and dilated 10th antennal segment, and from the former by the very elongate segments of the flagellum

“Practical elimination” principle in the Akkuyu Nuclear Power Plant design

The paper considers the implementation of the “practical elimination” principle in the design of the Akkuyu NPP with VVER1200 reactors being under construction in Turkey. The “practical elimination” principle is defined as follows: for accident sequences or phenomena that contribute or lead to unacceptable radiological consequences for the public or the environment, it shall be shown with a high level of confidence that their occurrence is highly unlikely. “Practical elimination” is proved predominantly by results of a Level 2 probabilistic safety assessment. The implementation of the “practical elimination” principle was considered at the level of accident sequences leading to a large radioactive release. It has been shown that each accident sequence leading to an unacceptable release has the probability of occurrence below 4.45Е–8 per reactor per year, while their total probability not exceeding the value of 6.17Е–7 per reactor per year. For the phenomena inside the containment area during severe accidents, including hydrogen detonation, a large thermal explosion, direct containment heating, overpressure in the containment volume, and the containment damage at later stages due to the basement melting through, their “practical elimination” has been demonstrated. The paper also considers specific hard-to-assess scenarios of beyond design basis accidents, for which the applicability of the “practical elimination” principle is assessed as well: a major positive reactivity insertion, a rupture of the reactor pressure vessel and other largescale components, damage of fuel elements in the spent fuel pool, severe accidents with the containment bypass or containment failure, and severe accidents accompanied the means for mitigating with their consequences being unavailable. Criteria have been developed and used for the “practical elimination” assessment. A sensitivity analysis was undertaken as part of the Level 2 probabilistic safety assessment which has shown that estimated values slightly depend on the analytical assumptions, as well as on the random change in the parameters that the affect the progression of severe accidents

OSOBENNOSTI STRUKTURNOY ORGANIZATsIISUSTAVNOGO KhRYaShchA v zavisimosti ot stadii gonartroza

The purpose - revealing of features of the structural organization of the articulate cartilage of a knee joint at patients with various stages of arthrosis. Materials and methods. Morphological researches of an articulate cartilage are visited at 52 patients with various stages of gonarthrosis. The control group was made by 5 men and 5 women in the age of from 18 till 25 years with traumatic damages of components of a knee joint. The basic group was made by 42 persons. On a stage of gonarthrosis patients have been divided into 2 subgroups: 23 patients with 1-2 stage and 19 patients with 2-3 stage of gonarthrosis. The histological material for research has been received at performance medical-diagnostic arthroscopies a knee joint. Results. It is noted, that morphological changes in an articulate cartilage at gonarthrosis are connected with change of density intercellular matrix and, depending on a stage of process, of chondrocyte dystrophy, necrosis and apoptosis are took place. In cytoplasm of chondrocyte there is a decrease in concentration of cytoplasmic organelles, lipids accumulation and electron density inclusions. Conclusion. The most expressed structural changes in the articulate cartilage, connected with local destruction of chondrocytes, lipids and electron density inclusions accumulation are noted at patients with 2-3 stage of gonarthrosis
