A team of scientists from the Institute of Civil Engineering and the Institute of Power Engineering at SPbPU, together with the Technological University of Havana "José Antonio Echeverría" (CUJAE), have developed a decision-making model aimed at optimizing the operation of electric power systems during extreme weather events. The project is being implemented with funding from a grant from the Ministry of Science and Higher Education of the Russian Federation.

In September 2025, an online meeting of the project teams was held to outline the project's scientific objectives. In October 2025, during a visit to the St. Petersburg Polytechnic University by a delegation from the Technological University of Havana "José Antonio Echeverría," Rector Marta Dunia Delgado Dapena and CUJAE Director General of Information, Communications, and Information Technology Naima Cepero Pérez reviewed the project's interim results. They praised their significant significance for Cuba.

The likelihood of power grid failures increases significantly during extreme weather events. Overhead power line outages can lead to a complete or partial disruption of power supply to consumers. The project aims to minimize the number of consumers without power.

The project's main result is a decision-making model that allows for determining the operating mode of the electric power system that will supply the greatest number of consumers with electricity. This model is presented as a digital solution based on a genetic optimization method. The research team has already received an application for practical implementation from its industrial partner, the RIO Design Bureau.

The scientific and technical results obtained as part of the project determine the optimal operating mode for the electric power system under extreme weather conditions. The proposed approach is intended for use in power system control centers to implement measures aimed at reducing the proportion of consumers without power. This scientific result is of particular value for Russia and the Republic of Cuba, as the problem of climate-related power outages in both countries is particularly acute and has not yet been fully resolved, noted Vyacheslav Burlov, Associate Professor at the Higher School of Technical Biology.

166 years since the birth of Anton Chekhov

Anton Pavlovich is a classic of world literature, a writer, and playwright with a medical education. He wrote over 300 works during his lifetime.

Childhood and youth in Taganrog

Chekhov was born in Taganrog into a large merchant family. From childhood, he was accustomed to hard work: he sang in the church choir, studied diligently, helped his father in the grocery store, and even learned to be a tailor. His parents instilled in him not only a hard work ethic but also other important qualities: compassion, respect for people, and a love of nature. While still in high school, he began writing his first short stories and sketches under the pseudonym "Chekhonte," given to him by one of his teachers.

After his family moved to Moscow in 1876, 16-year-old Anton remained alone in Taganrog. To support himself, he tutored and wrote essays. He sent short sketches of Taganrog life, such as "The Stammerer," to his brothers in Moscow. His first play, "Fatherlessness," was also published around that time. It explored spiritual crisis and the loss of moral compass.

The beginning of the journey in Moscow

In 1879, Chekhov moved to Moscow, where he took on the responsibility of caring for his family, living on the modest income from his literary publications. This year proved to be a landmark one for him:

His debut in print: the short story "Letter to a Learned Neighbor" and the humorous piece "What is Most Common in Novels, Stories, etc." His university entrance exams: He enrolled in the medical faculty of Moscow University (now Sechenov University).

While still a student, Chekhov began his medical practice, working as a district doctor and later as the head of a hospital in Zvenigorod.

The development of a writer and mature work

In 1884, Chekhov's first book, "Tales of Melpomene," was published, followed by the well-known collections "Motley Stories" (1886), "In the Twilight" (1887), and "Gloomy People" (1890). In the late 1880s, he actively worked for the theater, creating the plays "Ivanov," "The Wood Goblin," and "The Wedding," as well as the famous vaudevilles "The Bear" and "The Anniversary." Seeking inspiration and new experiences, Chekhov traveled extensively, visiting Nizhny Novgorod, Sakhalin, Yasnaya Polyana, and Western Europe.

In 1892, the writer moved to the Melikhovo estate near Moscow. Here, he actively helped people: as a doctor, he treated peasants, built schools, traveled to areas ravaged by famine, and participated in the general census. It was in Melikhovo that his most famous works were created: the play "The Seagull," the novella "Ward No. 6," and the short stories "The House with a Mezzanine" and "The Man in a Case."

Recent years and recognition

Chekhov spent his last years in Yalta, where he worked on the play The Cherry Orchard and received numerous guests, including Maxim Gorky, Ivan Bunin, and Leo Tolstoy, who called Chekhov "an incomparable artist of life" and "Pushkin in prose."

Chekhov's contemporaries and descendants highly valued him as an innovator. They noted his unique talent for revealing the profound psychology of his characters through everyday details, while the laconicism and radiant humanism of his prose elevated realism to the level of philosophical generalization. He is rightly considered a master whose work enriched not only Russian but also world literature.

Anton Pavlovich Chekhov's work remains relevant because it speaks not of events, but of the eternal: the fragility of the human soul, the search for meaning in everyday life, and the courage to live despite the imperfections of the world. This makes him not just a classic, but our insightful contemporary.

In 2025, Red Wings Airlines operated 24,000 flights on Russian aircraft and carried over 2 million passengers. The company's services were also used to transport two barn owls, an eagle, a brown bear cub, and a swarm of bees, totaling approximately 2 tons.

The core of the Red Wings fleet consists of Tu-204/214 and SSJ-100 aircraft, manufactured by the United Aircraft Corporation (part of Rostec State Corporation). Red Wings exclusively uses Russian aircraft on scheduled routes. The airline has also operated approximately 1,000 charter flights on long-haul Boeing 777s.

The airline revised its charter program and increased the efficiency of its domestically produced aircraft fleet. As a result, Red Wings' total passenger traffic reached 2.7 million, comparable to 2024 figures.

The average load factor on flights increased by 2%, with the majority of traffic going to international destinations. Red Wings also increased passenger traffic on domestic routes. Last year, the airline's passengers most frequently chose flights to Yekaterinburg, Moscow, and Sochi, while international flights were mostly to Thailand.

In 2025, Red Wings significantly expanded its route network, launching 25 new scheduled destinations: 17 within Russia and 8 internationally. This expanded flight network helps address the strategic objective of increasing connectivity between Russian regions, and allows thousands of passengers to enjoy convenient, direct flights without lengthy and tedious transfers.

NordStar Airlines has summed up its production results for 2025.

NordStar Airlines has summarized its operational results for 2025. Over the 12 months of 2025, the airline demonstrated stable growth in key performance indicators compared to the previous period: 1,265,000 passengers were carried on its own flights, with passenger turnover reaching 3,276 million passenger-kilometers. Annual flight hours totaled 28,995. The airline transported 4,303 tons of mail and cargo in 2025.

More than half of the airline's key performance indicators are driven by the extensive route network of its home base, Norilsk. In 2025, the airline operated scheduled flights from Norilsk to 20 destinations. Scheduled flights to Gelendzhik and Krasnodar, previously restricted, were reinstated. More than 600,000 passengers were carried, with annual passenger turnover exceeding 1.514 billion passenger kilometers. Flight hours on Norilsk routes totaled 14,318. Mail and cargo volumes totaled 3,420 tonnes.

"2025 was marked by the development and enhancement of passenger accessibility and loyalty. One of the key objectives in this regard was the opening of our own ticket and service sales offices in the Norilsk Industrial District. In the summer of 2025, two sales offices were opened – in Norilsk and Talnakh – and for six months, they have been providing passengers with a full range of services face-to-face, including information, flight selection, and ticket booking. The development of sales office services will continue in the next period," notes Leonid Mokhov, CEO of NordStar Airlines. "Another step toward strengthening loyalty was the global update of the "Flying is Easy!" frequent flyer loyalty program. The new program is more passenger-focused and will soon offer significantly more opportunities for independent planning of how to use privileges."

Particular attention is being paid to developing internal competencies. 2025 marks an active phase of development for the Aviation Training Center, with the expansion of training programs. Currently, the Aviation Training Center offers initial flight attendant training for the Boeing 737 NG, pilot training in emergency rescue procedures (ERP), and initial and recurrent flight attendant instructor training. This marks a new stage in the company's efforts to build a sustainable talent base and maintain quality onboard service. It also marks the first step toward independent learning—anyone interested in pursuing a career in aviation with the goal of eventually finding employment with Russian airlines can take this training.

In 2026, the airline is focused on further expanding its flight geography, while maintaining a priority focus on maintaining a consistently high level of flight safety, as well as improving service levels to ensure the most comfortable travel experience for every passenger.
