The Tale of the Battle of Kalka in Russian Chronicles of the 13th–18th Centuries
Authors: Астайкин А.А. 
Published: September 2023

В статье произведен текстологический разбор и хронологически систематизированы сообщения русских летописей о битве на реке Калке 1223 г. (сохранившиеся в форме полной или фрагментарной особой Повести и кратких сообщений). В комплексе летописных известий внимательно рассматриваются все фактические данные (имена, количество войск и потерь, детали хронологии и географии, последовательность и участники событий) и на этой основе фиксируются позднейшие текстуальные наслоения или утраты. В результате проделанного анализа выделяются как наиболее достоверные варианты Повести три ранние летописи – Новгородская I (особенно), Ипатьевская (с оговорками) и Лаврентьевская. За ними следует группа погодных хроник, несущих сокращенный вариант Повести новгородского происхождения (Новгородская IV и V, Новгородская Карамзинская летописи, Новгородская летопись по списку П.П. Дубровского). На третьем месте по надежности сведений поставлена группа общерусских летописей XV–XVII вв. (Софийская I, Московско-Академическая, Вологодско-Пермская, Воскресенская летописи, Тверской сборник как Пространная редакция Повести и др.), представляющих интерес исключительно с точки зрения литературной истории текста. Недостоверные краткие сообщения (кроме текста «Никифора патриарха Царяграда летописца вскоре») и требующие всесторонней проверки известия русских летописей XVII и XVIII в. оговорены особо.
The article presents a textual analysis and chronicle categorization of paragraphs from different Russian Chronicles depicting the Tales of the 1223 Battle of Kalka. The factual data has been thoroughly examined (including names, number of troops and losses, chronicle and geographical details, sequence, and participants of the historical events) These create a basis for further investigation of textual overlap or possible losses. As a result, three chronicles have been derivated as the most authentic — the First Novgorod Chronicle, the Laurentian Codex, and the Hypatia Codex. They are followed by a group of annual chronicles consisting of a shortened variations of the Novgorodian Chronicle (the Fourth and the Fifth Novgorodian Chronicles, Novgorodian Karamzin Codex, Novgorodian chronicle according to P.P. Dubrovsky’s list). The third level for reliability of the data is a set of the all-Russian chronicles of 15th—17th centuries (the First Sofia’s Codex, Moscow Academic, Vologda-Perm, Voskresenskaya chronicles, Tver collection as a Vast edition of the Tale, etc.). These are of an interest exclusively in relation to the literary history of the text. The unreliable short chronicle records (except the text of Patriarch Nicephorus the annalist of Tsarigrad) that require comprehensive examination for the news of the Russian chronicles of 17th and 18th centuries are otherwise noted.

Authors: Pyzhev A. I. 
Published: September 2023

Aim. To analyze the potential and directions of development of the Russian pulp and paper industry taking into account the historical retrospective and international comparisons.Tasks. To analyze the historical retrospective of the dynamics of pulp and paper production volumes in Russia taking into account the spatial distribution of the industry’s production capacities; to assess the potential for growth of domestic demand for the pulp and paper industry products on the basis of international comparisons.Methods. The research was carried out by means of system analysis of the industry development on the basis of statistical reconstructions and international comparisons.Results. The Russian pulp and paper industry for thirty years after the collapse of the USSR overcame the transformation crisis and returned to the peak production volumes, bringing the technological level and the nomenclature of products to the level of the leading countries. As a result of transformations, there was an excessive concentration of the sector’s production capacities in the European part of the country, which in modern conditions leads to difficulties in marketing export-oriented products. The gap in the levels of per capita consumption of certain types of paper and paperboard products in Russia compared to the leading forestry countries indicates the possibility of further growth of domestic demand for the sector’s products.Conclusions. The growth of pulp and paper industry production volumes can be associated with the growth of the domestic market, which will require the outstripping growth of the population’s income.

Published: September 2023

Aim. To analyse investment activity in modern Russia in the context of new conditions and tasks of the country’s economic development, as well as to identify the directions of its stimulation and development.Tasks. To analyse the current state and prospects of development of the Russian economy in the context of external sanctions; to study and assess the level and features of business investment activity in modern Russia; to propose tools and directions of stimulation and development of investment, considered as a way to restart the mechanisms of economic growth.Methods. The methodological basis of the research was the provisions of macroeconomic theory, in particular such sections as the theory of economic growth, the theory of state regulation of the economy, the theory of investment. The methods of comparative and retrospective analysis, structural modelling, analogy, expert evaluation and qualitative methods of forecasting were used.Results. It has been established that the Russian economy has entered the period of development characterised by high uncertainty of the main influencing factors. This negatively affects the behaviour of economic entities and weakens the potential for economic growth. One of the important factors of growth and sustainable economic development is investment. Despite the external sanctions pressure on the Russian economy, there was no decrease in investment activity in 2022. On the contrary, it has increased. This is a prerequisite for successfully overcoming the current crisis phenomena in the economy and further successful development of the national economy. At the same time, a number of problems restraining the investment activity of Russian business have been identified.Conclusions. In modern conditions, the issues of creating effective incentives to support and develop the investment activity of Russian companies have become more relevant. The relevant measures should be built into a new model of economic policy aimed at creating the potential for long-term economic growth in Russia in post-normal conditions. These measures are related to the activities of development institutions acting as sources of “long” and “cheap” money, as well as to the adjustment of fiscal policy, oriented towards the creation of additional incentives for the growth of investments of economic entities.

Algorithm-Aware Qubit Mapping
Authors: Ji Yanjun , Polian Ilia 
Published: September 2023

<p>Algorithm-aware (AlgAw) qubit mapping aims at directly providing the solutions to qubit mapping of algorithms with regular structures based on the algorithm's features. Although exact methods can provide high quality solutions, their compilation time grows exponentially with circuit size. To improve scalability, we propose the AlgAw qubit mapping approach. The main idea is to first identify subcircuits in an algorithm to be mapped, then analyze optimal solutions for small scale subcircuits found by exact methods, extend these solutions to large scale subcircuits, reconstruct the entire circuit and assign parameters, and finally map pretranspiled circuits onto the target quantum devices. Applying AlgAw to the quantum approximate optimization algorithm (QAOA) on linear and T-shaped subtopologies produces optimal and scalable solutions for arbitrary numbers of qubits and depths, which is critical to the algorithm's performance on near-term quantum devices. Compared to other methods including Qiskit, Tket, and SWAP-network, AlgAw produces the least number of CNOT gates and the lowest circuit depth for the pretranspiled circuits. Furthermore, AlgAw takes only a few seconds to construct a resulting circuit having a hundred qubits. The benchmarking results on IBM quantum devices show that AlgAw qubit mapping yields better performance than others. AlgAw is applicable to other variational quantum algorithms (VQAs) and can also be applied to other algorithms.</p>
Reducing the cost of industrial decarbonization: Demand response by combined product and energy storage for chlor-alkali electrolysis and vinyl chloride monomer production
Authors: Foslie Sverre Stefanussen , Straus Julian , Knudsen Brage Rugstad , Korpås Magnus 
Published: September 2023

<p>Industrial demand response will become increasingly important in power grids with high shares of variable renewables, yet the existing knowledge on how the industrial electricity demand and flexibility will change with decarbonization of chemical processes is limited. </p>
<p>Here we develop a mixed-integer linear optimization model which we use to compare cost and flexibility of the most relevant decarbonization options for the combined chlor-alkali electrolysis (CAE) and vinyl chloride monomer (VCM) production process. We combine product and energy storage to enable the full flexibility potential of the decarbonized process. </p>
<p>Our results show that flexible operation of the CAE process is deemed technically possible but limited by internal process dependencies due to decarbonization of the VCM production. Combining energy and product storage for demand response enables up to 4~\% operational cost reduction by shifting loads during peak price hours. High overcapacity of PEM electrolyzers are required to release the full flexibility potential in the hydrogen based decarbonization option, while the less flexible direct electrification option shows a potential for OPEX reduction.</p>
<p>Full decarbonization of the combined CAE and VCM process without increasing operational cost significantly appears difficult. Our study emphasizes demand response through product and energy storages as a viable pathway for minimizing the added cost, and also enables significant reduction of electric demand in high-price hours. </p>
Robust Detection Method of Low-Voltage Islanding for Grid-Forming Inverters Operated in Conjunction with Existing PV Inverters
Authors: Winter Björn Oliver , Schwung Julian , Engel Bernd 
Published: September 2023

With the gradual exit from fossil and nuclear based power generation, a
replacement for the reducing grid inertia is urgently needed. Due to
this reason, grid-forming inverter technology is discussed as possible
future replacement but will need to be implemented in massive scales to
be an adequate source of transient grid stability. Therefore, different
projects, such as ‘Grid Control 2.0’ or ‘VerbundnetzStabil’ have looked
into the potential for grid integration of grid-forming inverters down
to the low-voltage level to utilize as much future renewable grid
integration for inertia provision as possible. However, the
incorporation of grid-forming converters that lack dependable islanding
detection mechanisms may significantly diminish the efficacy of current
procedures employed by existing grid-following converters. Consequently,
islanded grids that emerge due to faults or planned maintenance may not
be reliably deactivated during a fault.
This paper presents a solution for detecting islanding in grid-forming
converters. The authors analyze the limitations of a commonly used
active islanding detection method (slip-mode frequency shift) on a
grid-following inverter, whose basic assumptions are undermined if a
grid-forming system is operated in parallel and propose an adapted
detection procedure for grid-forming converters. The proposed
‘-Q-f-droop’ method is shown to be capable of reliable islanding
detection in both standalone and interconnected operation with existing
plants by non-detection zones created with a suitable setup in
simulation. The results are verified through laboratory tests using
grid-following and grid-forming PHIL inverters. The developed method
ensures reliable shutdown of formed island grids even with the
integration of grid-forming systems into the low-voltage level.
