В последнее время на страницах научной литературы все чаще обсуждаются вопросы человеческого и интеллектуального капитала и его вклада в социальное и научно-технологическое развитие общества. Независимо от мнений специалистов можно говорить об однозначности роли фактора питания и здоровья в формировании человеческого и интеллектуального капитала. Это, в свою очередь, предполагает организацию здорового питания с точки зрения всех его аспектов, в том числе обеспечение ассортиментом продуктов питания с высокой пищевой и биологической ценностью. В перечне однородных групп пищевых продуктов представляет интерес рыба и продукты ее переработки как источник многих незаменимых нутриентов. Экономические санкции против России оказали значительное влияние на пищевой промышленный сектор, но также послужили стимулом для развития отечественного производства. В этой связи актуально проведение исследований состояния рынка рыбного сырья как в целом России, так и в ее субъектах с целью выявление перспектив его развития. Проведены комплексные исследования рынка рыбной продукции г. Кемерово, а именно: основные производители и структура ассортимента потребительского рынка, уровень потребления с целью оценки рыночных ресурсов и дальнейшей разработки маркетинговой стратегии устойчивого развития рыбной отрасли в условиях малого предпринимательства региона. Результаты исследований выявили определенный уровень сформированности рынка рыбной продукции для обеспечения населения за счет рыбы ввозимой из зарубежных стран торговых партнеров, российских восточных регионов, а также продукции местных производителей. Наличие государственной и региональной стратегий обеспечения населения собственной продовольственной продукции, предполагающей в том числе организационную и финансовую поддержку, благоприятствует развитию рыбоводства в Кемеровской области – Кузбассе.

Впервые создан винный напиток мадера из винограда французских сортов, выращенного в предгорье Алтая. Актуальность и новизна исследований заключается в перспективах внедрения в промышленное производство. Представлены результаты анализов виноградных соков натуральных, виноматериалов свежеприготовленных и после длительной выдержки. Показано, что в соках Пино Нуар и Гаме высокий уровень сахара 19,0–20,5 г/100г, титруемая кислотность 10,1–9,8 г/дм3, что несколько выше нормы (8 г/дм3). Содержание полифенольных веществ 2590–2610 мг/дм3 характеризует виноградное сырье как высококачественное. Виноматериалы приготовлены методом микровиноделия практически до полного сбраживания сахара 0,36–0,59 г/дм3. Естественная аккумуляция спирта – 12,2–11,4 % об., летучих кислот – 0,36–0,59 г/дм3, что не превышает норму ПДК. При брожении в результате окислительных процессов произошло снижение полифенолов в Пино Нуар – 2230 мг/дм3, за счет восстановительных процессов увеличилась сумма полифенолов в Гаме – 2800 мг/дм3.. Во время длительной выдержки содержание полифенольных соединений снизилось незначительно. Мадеризация виноматериалов осуществлялась при температурном режиме 50 ºС на протяжении 45 суток в стеклянных емкостях с добавлением дубовых клепок. Аэрацию проводили методом перелива из емкости в емкость. Восстановительные процессы, протекавшие во время мадеризации, повысили уровень полифенолов до 2650‒2810 мг/дм3. Титруемая кислотность в образце из сорта Гаме превысила норму – 12,9 г/дм3. После мадеризации проведена оклейка виноматериалов суспензией бентонита и желатина, скорректирована кислотность способом мелования, произведена фильтрация, подслащивание сахарозой и корректировка по спирту. Винный напиток мадера из сорта Пино-Нуар с дегустационной оценкой 9,5 балла имеет яркий вкус с умеренной терпкостью и насыщенную ярко-гранатовую окраску. Незначительно ниже оценка винного напитка мадера из сорта Гаме – 9,0 баллов. Выявлено, что физико-химические показатели готовых винных напитков соответствуют нормируемым требованиям.

Представлены результаты экспериментального исследования повышения температуры модельных водных суспензий гексахлорэтана (ГХЭ) при их обработке в установке с многоцилиндровым роторно-пульсационным аппаратом (РПА). Приводится описание лабораторной установки, РПА и методики проведения исследований по оценке нагрева 1 и 4%-ных водных суспензий ГХЭ при их гидромеханической обработке. Для двух значений чисел оборотов ротора РПА (33,3 и 45,8с-1), а также для двух значений радиального зазора между цилиндрами ротора и статора (0,1·10-3 и 1·10-3м) получены экспериментальные данные по увеличению температуры модельных суспензий. В предположении, что вся подводимая к обрабатываемой среде механическая энергия переходит в тепловую и теплообмен с окружающей средой отсутствует, выполнена расчётная оценка нагрева суспензии. Показано, что при увеличении числа оборотов ротора РПА и концентрации суспензии, темп её нагрева возрастает. Уменьшение величины радиального зазора между цилиндрами ротора и статора способствует значительному разогреву суспензии. Отмечена удовлетворительная сходимость расчётных и экспериментальных данных по нагреву суспензий. Полученные сведения могут быть полезными при проектировании оборудования для обработки систем «жидкость–твёрдое».

В статье рассмотрено улучшение технологического процесса прессования политетрафторэтилена, с целью повышения его эксплуатационных свойств, долговечности и износостойкости для использования в полимерных композиционных материалах применяемых в деталях различных узлов трения. Проведено сравнение влияния технологических режимов прессования на механические свойства, триботехнические характеристики, рельеф поверхности трения, а также на надмолекулярную структуру политетрафторэтилена. В результате исследований установлено, что применение технологического режима ультразвукового прессования с частотой 17 кГц и одновременно наложенной низкочастотной амплитудной модуляцией 100 Гц для прессования изделий из политетрафторэтилена, позволяет повысить предел прочности при растяжении на 9 %, относительное удлинение на 9 %, модуль упругости на 6 % и снизить интенсивность массового изнашивания на 22 %, коэффициент трения на 24 %. Использование низкочастотной модуляции приводит изменению рельефа поверхности трения и к получению более равномерной, упорядоченной и однородной структуры ПТФЭ.

Based on expeditionary work in the period 2003–2018 we compile a map of linden forests locations in the Jewish Autonomous Region (JAR). An inventory map of forest fires was created using data on forest fire registration of the Forest Management Department of the JAR Government for 2017–2020. The number, area, and configuration of the burned areas were determined by superimposing of these maps. The analysis of fire-damaged forests shows that during the study period fires were observed in all forest formation with linden. Their total number was 174. The most of fires (33%) noted in 2018 and the fewest (15%) – in 2017. The average annual number of fires in 2017–2020 was 44. The largest area affected by the pyrogenic factor was observed in 2018. The smallest area (7.5%) of linden forests were fire-transformed in 2020. The average area of one fire is 653 hectares. This corresponds to 64% of the total fire-affected area in the studied vegetation formations. The black birch and oak park-type forests, sometimes with linden, larch, with silverspike-and-forbs cover and forbs-and-pinegrass meadows were most affected by fire. We analyzed the spatial distribution of the fire-damaged forests and established its main patterns as well as identified the areas of repeated burnout. In the most of the JAR linden forests fires have a one-time character. Local areas are subject to multiple burnout; the causes of their high multiple ignition require further study. In this regard, forest fires is a factor that significantly contributes to the reduction of the honey-bearing lands of the JAR.

Dans le cadre du questionnement sur la caractérisation de l’éthique appliquée, nous mettons à l’épreuve la cordée de la réussite SOAN. Cette cordée se donne pour objectif de sensibiliser les apprenants, du collège à l’université, aux métiers du numérique et à ses aspects genrés. Nous tentons plus particulièrement de comprendre en quoi la construction des représentations de genre au sein d’un contexte de formation comme la cordée SOAN, ne semble pas toujours participer à la construction d’une éthique communicationnelle. Pour cela, nous prenons appui sur nos résultats de travaux de recherche réalisés auprès des apprenants de la cordée SOAN. Ces résultats nous amènent à nous interroger sur le choix des actions et des activités proposées au sein de cette cordée mais aussi sur son organisation en tant que dispositif.

El personal de salud a través del tiempo ha demostrado ser fundamental para la preservación del bienestar del ser humano; sin embargo, la formación que debe llevar para lograrlo no es la fórmula para alcanzar su salud propia. El presente trabajo pretende analizar las principales adversidades que experimentan los estudiantes de medicina durante su proceso de formación profesional, con el fin de motivar las reformas de los campos formativos. Es una investigación documental con información basada en la evidencia científica. Se encuentra que en México y América Latina son muchos los médicos que ingresan a la licenciatura en medicina, pero a la vez existe un porcentaje elevado que desertan, lo cual está relacionado con padecimientos que atentan directamente contra su integridad, como ansiedad, depresión, burnout, ideación suicida, adicciones y otras condicionantes económicas, familiares y sociales. Se encontraron índices de deserción hasta del 25%, que se sostienen o incluso se elevan con el paso del tiempo, por lo que se requiere atender esta problemática, sensibilizar a los diferentes sectores de la sociedad, pues el personal médico pese al cansancio o la sobrecarga, aun así, otorga la atención requerida por los usuarios y usuarias, muchas veces a costa de su bienestar propio.

Background: The main objective of this work is to describe the findings and radiological evolution on chest CT of 27 patients with COVID-19 pneumonia after being treated with LD-RT in a prospective study. We also evaluated the interobserver agreement in assessing the extent of lung involvement. Patients and Methods: 3 CTs were compared: day of treatment, one week later, and at 4-7 months. In each CT the following radiological findings were evaluated in each lobe: extension score (0: none, 0%; 1: minimal, 1-5%; 2: mild, 5-25%, 3: mild-moderate, 26-50%; 4: moderate, 51-75%; 5: severe, 76-100%), GGO, consolidation, crazy-paving pat-tern, subpleural lines, parenchymal bands, and pulmonary fibrosis. Results: A statistically significant decrease in the number of affected lobes with consolidations and GGO was found between the second and third CT (p=0.023 and p=0.003, respectively) and between the first and third CT (p=0.012 and p=0.006). No significant changes were identified regarding the presence of fibrosis. There was a significant decrease of the extension score when comparing the three studies (1st vs 2nd p=0.029, 2nd vs 3rd p<0.001, and 1st vs 3rd p<0.001). A very good concordance was found in the evaluation of the extension score and the presence of consolidations, there was a moderate agreement when assessing the fibrosis and only a mild agreement on the GGO. Conclusions: Our study suggests that patients with COVID-19 pneumonia treated with LD-RT show radiological improvement of consolidations and GGO on long-term follow-up chest CT, with no significant increase in pulmonary fibrosis identified.

Dysembryoplastic Neuroepithelial Tumor (DNET) is a benign glioneuronal neoplasm that most frequently affects children and young adults. It can cause chronic seizures that are medically refractory. This tumor’s cortical architecture and absence of a bulk effect or perilesional edema on radiographs are its defining features. The most typical manifestation of seizures is focal seizures with impaired awareness. Three DNET histologic subtypes have been identified. For either complicated or simple DNET types, histological detection of a distinct, particular glioneuronal component in brain tumor samples from individuals with medically refractory, chronic epilepsy serves as a diagnostic characteristic. We present one case of a child diagnosed with DNETs, who arrived at the hospital following seizures. The clinical, radiographic, histological, immunohistochemical, and molecular genetic characteristics characteristics of all three forms of DNETs as well as the differences between DNETs and gangliogliomas will be the main topics of this review.

To date, scientific evidences document the negative impact of COVID-19 on the health status and physical performance of both people in general and athletes. Furthermore, many studies highlight how the impact of SARSCoV- 2 infection does not end with the acute phase - two/three weeks - but the symptoms, first of all fatigue, can persist even for many weeks in what is called the long COVID-19 syndrome. However, we have little evidence regarding the COVID-19 pandemic per se and in particular the impact of lookdown strategies on the health of individuals and non-professional athletes. The aim of the present study was to evaluate the negative impact of COVID-19 pandemic in a group of amateur runners who signed up for the 2021 edition of RomaOstia half marathon.
Single-Atom Ligation of Four Different Alcohols at One Silicon Center: Methodology Development and Proof of Concept

Published: April 2024

Click chemistry continues to impact the chemistry and biology community, with the most well-known being the CuAAC click chemistry. Topologically, the CuAAC click chemistry only ligated two fragments in a two-dimensional manner. While the SuFEx and PFEx chemistry could ligate fragments three-dimensionally, maximally three fragments (amine/alcohol) could be clicked together for now. Herein, we report the three-dimensional single-atom ligation of four different fragments (alcohols) at one silicon center using triphenylchlorosilane as the ligation hub in an iterative, controllable, and programmable fashion. To fulfill the mission, we established a new silicon-phenyl exchange reaction with alcohols. A broad spectrum of alcohols could be ligated using various types of phenylchlorosilanes as ligation hubs, affording a library of mixed-dialkoxysilanes, trialkoxysilanes, and tetraalkoxysilanes. Notably, fully heteroleptic tetraalkoxysilanes were barely known in literature and extremely difficult to access in a selective fashion from a retrosynthetic viewpoint. Our protocol thus provided a robust solution to materials of such nature. To highlight the application potential, four different biologically relevant alcohols, representing four different functions, were successfully ligated to one Si(IV) center as fully heteroleptic tetraalkoxysilane. More importantly, the four alcohols could be released and recovered via silicon-alkoxy exchange of the stable yet cleavable Si-O bonds.

Published: April 2024

The chemistry of low-valent bismuth compounds has recently unlocked new concepts in catalysis as well as unique electronic structure fundamentals. In this work, we describe the synthesis and characterization of a highly-reduced bismuth salt featuring a cationic core based on three contiguous Bi(I) centers. The triatomic bismuth-based core holds an electronic situation that mimics the description of the archetypical carbonbased π-allyl cation. Structural, spectroscopic and theoretical analyses validate the unique π-delocalization between the bismuth’s highly diffused 6p-orbitals, resulting in a 1.5 bond order between the Bi atoms. This electronic situation places this complex as the heaviest and non-radioactive π-allyl cation of the periodic table. Furthermore, we demonstrate that the newly synthesized complex is able to act as a synthon for the transfer of a Bi(I) cation to forge other low-valent organobismuth complexes.
BOTTS: Rapid viscoelastic master curves through broadband optimized time-temperature superposition of windowed chirps from widely available DMA equipment
Authors: Sheridan Richard , Zauscher Stefan , Brinson Catherine
Published: April 2024

Modern materials design strategies take advantage of the increasing amount of materials property data available and increasingly complex algorithms to take advantage of that data. However, viscoelastic materials resist this trend towards increased data rates due to the very material time-dependence that should be measured. Therefore, viscoelasticity measurements present a roadblock for data collection in an important aspect of material design. For thermorheologically simple materials, time-temperature superposition (TTS) has for many years provided a method to accelerate relaxation spectrum measurements relative to, for example, very long creep experiments. However, TTS itself currently faces a speed limit originating in the common logarithmic discrete frequency sweep (DFS) mode of operation. In DFS, measurement time is proportional (by a factor much greater than one) to the lowest frequency of measurement. This state of affairs has not improved for TTS for half a century or more. We utilize recent work in experimental rheometry on windowed chirps to collect three decades of complex modulus data simultaneously. Furthermore, the three-decade chirp response is recorded in the time it would take to collect only the lowest frequency data point of a traditional DFS experiment, resulting in a 500% speedup in data collection. In BOTTS, we superpose several isothermal chirp responses to produce a master curve in a fraction of the time of the traditional DFS-TTS technique. The chirp responses have good, albeit nontrivial, signal-to-noise properties. We use linear error propagation and a noise-weighted least squares approach to automatically incorporate all the data in a reliable shifting method. Using model thermoset polymers, we show DFS-TTS and BOTTS results are comparable, and therefore BOTTS data represent a first step towards a fast, reproducible method for master curve generation from existing rheological measurement instruments.
Calculation of quasi-diabatic states within the DFT/MRCI(2) framework: the QD-DFT/MRCI(2) method
Authors: Neville Simon , Schuurman Michael
Published: April 2024

We describe a procedure for the calculation of quasi-diabatic states within the recently introduced DFT/MRCI(2) framework [J. Chem. Phys., 157, 164103 (2022)]. Based on an effective Hamiltonian formalism, the proposed procedure, which we term QD-DFT/MRCI(2), has the advantageous characteristics of being simultaneously highly efficient and effectively black box in nature, while directly yielding both quasi-diabatic potentials and wave functions of high quality. The accuracy and efficiency of the QD-DFT/MRCI(2) formalism are demonstrated via the simulation of the vibronic absorption spectra of furan and chlorophyll a.

Authors: Petrykiva Olga , Hordiienko Kristina
Published: April 2024

clientele. Banking marketing, with its unique attributes, stands as a distinctive domain within the broader spectrum of marketing. In an era where banks primarily offer uniform services, competition among them has intensified substantially, necessitating a shift towards maximum customer-centricity and the application of marketing concepts. This research aims to investigate the theoretical and methodological underpinnings and formulate practical recommendations for enhancing the marketing support of banks, facilitating effective functioning, and establishing a diagnostic framework for assessing the utilization of marketing tools. The core tasks include a comprehensive examination and synthesis of the theoretical foundations of event marketing as a banking marketing instrument in the context of globalization and an analysis of the marketing activities of PJSC "PrivatBank" with subsequent recommendations for refining the management of its event marketing endeavors.

In the current landscape, banks face multifarious challenges, including the repercussions of financial crises eroding client trust. The imperative lies in resuscitating the image of Ukrainian banks and enhancing marketing strategies that encompass a significant portion of the domestic banking sector's activities. These imperatives are increasingly pertinent due to factors such as limitations on price competition, internationalization of economic processes, adoption of foreign banks' products in Ukraine, and the proliferation of information technologies, expanding the purview of banking institutions' operations. To address emerging challenges, banks intensify their marketing efforts, focusing on refining products and services, developing new products, expanding customer relationship programs, monitoring competitors' activities, and fostering a marketing culture.

Banking marketing risks are systemic functional threats linked to a bank's positioning in the market environment, and the efficacy of banking systems' functioning hinges on the ability to proactively respond to potential threats. The collection, processing, and analysis of information regarding prior experiences in marketing support of banking activities, as well as monitoring and forecasting threats and indicators affecting banking security, fall within the methods employed to safeguard operations.

In summary, the utilization of event marketing techniques in banking activities assumes paramount significance in contemporary times, addressing heightened competition and customer trust as pivotal concerns. This endeavor offers the opportunity to refine marketing strategies, capture customer attention, and enhance the efficiency of banking operations.

With the help of indicators and KPIs, companies can get an overview of their performance at an operational or strategic level.
Problems of determining the borrower's creditworthiness
Authors: Miroshnyk Oleksii , Shubina Svitlana , Shulha Valeriia
Published: April 2024

This article addresses the challenges associated with determining the borrower's creditworthiness. The authors define the borrower's creditworthiness as the ability to timely and fully meet debt obligations to the lender. This determination is based on an evaluation of the borrower's financial condition, forecast of business development, and other factors influencing the ability to repay the loan.

The authors identify internal and external factors affecting the creditworthiness of borrowers in Ukraine. Internal factors include the economic situation, regulatory policies, credit history, credit rating, and a lack of financial literacy. External factors encompass the global economic situation and the political climate.

The article also discusses challenges in determining the borrower's creditworthiness during times of war. The authors note that creditworthiness can sharply decrease during such periods due to factors such as reduced income, increased costs, decreased demand for goods and services, and an unstable economic situation.

To address these challenges during wartime, the authors propose the following recommendations:

Widespread use of artificial intelligence: AI enables the consideration of more factors affecting the borrower's creditworthiness and the adaptation of credit scoring models to changes in the economic situation.

Expansion of data on the borrower's financial condition: Financial institutions should utilize more data sources, including unstructured data such as social media and behavioral data, to assess the borrower's financial condition.

Development of new methods for assessing creditworthiness: Financial institutions should create new methods that account for the specific conditions of wartime.

Aluminum alloy 6061 is a versatile material widely used in aerospace, automotive, marine, and structural applications due to its mechanical strength, weldability, and corrosion resistance. Understanding and addressing fatigue is crucial for ensuring the reliable and safe performance of components made from this alloy. This study focused on predicting the fatigue life of aluminum 6061 at room temperature under axial loading conditions and evaluating the fatigue life at various stress ratios. The experimental S-N curve, derived from tension-tension fatigue loading tests, was instrumental in characterizing the material's fatigue behaviour under constant amplitude loading condition. The data obtained from these tests were then imported into ANSYS software, a widely recognized tool for finite element analysis and simulation. ANSYS was used to conduct a detailed numerical analysis to predict the fatigue life of aluminum 6061 at different stress ratios. The results from the experimental and numerical analyses exhibited good agreement, validating the accuracy of ANSYS software in predicting fatigue life at different stress ratios. This study demonstrated the effectiveness of employing a combined experimental and numerical approach for understanding fatigue behaviour in materials, particularly in terms of its applicability to different loading scenarios. The findings from this research provide valuable insights into the fatigue life of aluminum 6061 under diverse stress ratios, with the goal of enhancing material design and engineering processes. By leveraging the capabilities of ANSYS software in conjunction with experimental data, the study established a reliable methodology for predicting fatigue life, which is crucial for optimizing the performance and longevity of components subjected to cyclic loading in various industries.
Changing kinematics of the Ouse Fault during the Cretaceous–Neogene tectonic evolution of eastern Marlborough
Authors:   , Dwight James
Published: April 2024

The Ouse Fault and adjacent strata record the tectonic evolution of part of the East Coast Basin since the latest Mesozoic. The Ouse Fault is a significant inactive structure that separates contrasting domains of Cretaceous strata within the northern Clarence valley, northeastern South Island. Detailed structural mapping along the trace of the Ouse Fault, in combination with examination of oriented fault rock samples, has helped to resolve the kinematic history of the fault. Results suggest that extensional activity on the Ouse Fault commenced sometime between ~103--95 Ma during deposition of the Split Rock Formation. Activity on the Ouse Fault continued until about 86 Ma, with the fault possibly experiencing a brief reversal of dip separation around 90 Ma. The Ouse Fault was reactivated as a thrust fault during development of the Early Miocene oblique-convergent Pacific-Australia plate boundary along the east coast of New Zealand, when the fault likely formed part of the southeast-verging (in present-day coordinates) Flags Creek Fault System. The Ouse Fault accommodated a late phase of minor dextral-slip or oblique-reverse motion, most likely as a result of the transpressional deformation that has affected Marlborough since the Late Miocene.

The Champagne Formation constitutes a significant portion of the hanging wall of the Ouse Fault. The unit hosts spectacular deformation structures that formed penecontemporaneously with deposition. Previous studies postulate that the unit forms part of a mass-transport complex that was syn-tectonically emplaced with activity on the Ouse Fault. Results from this study suggest that the Champagne Formation was emplaced on a northeast-dipping paleoslope within the interval ~113–103 Ma, and that soft-sediment deformation within the unit predates the onset of motion on the Ouse Fault. The relationship between the Champagne Formation and the underlying Pahau Terrane basement remains ambiguous, with the unit possibly representing the youngest strata of the Pahau Terrane that were affected by widespread soft-sediment deformation. Results in this study accord well with a model of subduction shutdown beneath the Zealandia segment of eastern Gondwana sometime between ~105–100 Ma.

Authors: Zhou Zhi , Wang Yanchun
Published: April 2024

Microsatellite stabilized (MSS) rectal cancer is a highly prevalent cancer in the middle-aged and elderly population. There exists some expertise in detecting and evaluating the chemotherapy effect in advanced colorectal cancer patients. Multiple studies have combined targeted therapy, chemotherapy, and immunotherapy as a breakthrough. Programmed cell death protein 1 (PD-1) inhibitors have certain therapeutic effects in the treatment of MSS rectal cancer patients. The combination of PD-1 inhibitors and furoquinib can improve the disease control rate (DCR) and progression- free survival (PFS) in colorectal cancer (CRC) patients with advanced MSS, and the adverse reactions are controllable. The combination of erlotinib hydrochloride and Xindilizumab was more effective in treating MSS-type colorectal cancer patients than clinical standard treatment. This study analyzes the various treatment methods for MSS-type CRC in middle- aged and elderly people to provide a reference basis in clinical practice.
Coefficient inverse problem for an equation of mixed parabolic-hyperbolic type with a non-characteristic line of type change
Authors: Durdiev D. K.
Published: April 2024

In this paper, we study the direct and two inverse problems for a model equation of mixed parabolic-hyperbolic type. In the direct problem, the Tricomi problem for this equation with a non-characteristic line of type change is considered. The unknown of the inverse problem is the variable coefficient at the lowest derivative in the parabolic equation. To determine it, two inverse problems are studied: with respect to the solution defined in the parabolic part of the domain, the integral overdetermination condition (inverse problem 1) and one simple observation at a fixed point (inverse problem 2) are given. Theorems on the unique solvability of the formulated problems in the sense of classical solution are proved.

In this paper, the inverse spectral problem method is used to integrate a nonlinear sine-Gordon type equation with an additional term in the class of periodic infinite-gap functions. The solvability of the Cauchy problem for an infinite system of Dubrovin differential equations in the class of three times continuously differentiable periodic infinite-gap functions is proved. It is shown that the sum of a uniformly convergent functional series constructed by solving the system of Dubrovin equations and the first trace formula satisfies sine-Gordon-type equations with an additional term.
