Single-pixel deep phase-shifting incoherent digital holography
Authors: Chen Yifei , Zhang Qinnan , Liu Tianyun , Li Jiaosheng
Published: September 2024

Incoherent digital holography technology reduces the requirement for coherence of light sources, greatly expanding the application range of digital holography. In this paper, we designed a Multi-head attention single-pixel (MHASP) phase-shifting network for incoherent digital holography. The trained network has the capability to effortlessly predict three interferograms, encompassing phase shifts of 0, 2/3 π, and 4/3 π, solely from one-dimensional input data. Utilizing the conventional three-step phase-shifting method, we are able to effectively eliminate the DC and twin terms from the holographic reconstruction process, subsequently achieving a high-fidelity reconstruction facilitated by the employment of the back propagation algorithm. The comprehensive experimental findings clearly indicate that, beyond facilitating high-precision reconstruction, the introduced MHASP phase-shifting approach efficiently preserves 3D information through calibrating the back propagation distance, even when confronted with a reduced volume of holographic data. Furthermore, the introduced approach uses a network to replace the actual phase shift operation, which can better improve the utilization of object light energy. This approach not only circumvented the constraints posed by area array sensors but also facilitated high-fidelity imaging with minimal data volume, thereby expanding the horizons of incoherent digital holography applications in the realm of 3D imaging.

Published: September 2024

Imaging through scattering media still presents a challenge for modern optical imaging techniques. The problem becomes even worse for dynamic scattering scenes, e.g., to capture dynamic objects behind a scatterer or then the scattering medium itself is in constant movement, such as fog or living tissue. This contribution introduces a first step towards a potential solution, which builds upon our previous Synthetic Wavelength Imaging techniques. We showcase the feasibility of our approach by imaging an extended hidden object through a scatterer in single-shot.

The present study aimed to verify the impact of etiological treatment on the genotype-specific serological diagnosis of chronic Chagas disease patients (CH), using the Chagas-Flow ATE IgG1 methodology. For this purpose, a total of 92 serum samples from CH, categorized as Not Treated (NT, n = 32) and Benznidazole-Treated (Bz-T, n = 60), were tested at Study Baseline and 5Years Follow-up. At Study Baseline, all patients have the diagnosis of Chagas disease confirmed by Chagas-Flow ATE IgG1, using the set of attributes (“antigen/serum dilution/cut-off”; “EVI/250/30%”). The genotype-specific serodiagnosis at Study Baseline demonstrated that 96% of patients (44/46) presented a serological profile compatible with TcII genotype infection. At 5Years Follow-up monitoring, NT and Bz-T presented no changes in anti-EVI IgG1 reactivity. However, significant differences were detected in the genotype-specific IgG1 reactivity for Bz-T. The most outstanding shift comprised the anti-amastigote TcVI/(AVI), anti-amastigote TcII/(AII) and anti-epimastigote TcVI/(EVI) reactivities. Regardless no changes in the genotype-specific serology of NT (TcI = 6%; TcII = 94%), distinct T. cruzi genotype-specific sero-classification was detected for Bz-T samples at 5Years Follow-up (TcII = 100%) as compared to Baseline (TcII = 97%; TcVI = 3%). The anti-trypomastigote TcI/(TI) was the attribute accountable for the change in genotype-specific sero-classification. In conclusion, our findings of dissimilar T. cruzi genotype-specific serology upon Bz-treatment re-emphasize the relevance of accomplishing the genotype-specific serodiagnosis during clinical pos-therapeutic management of chronic Chagas disease patients.
Beyond six feet: The collective behavior of social distancing
Authors: Wu Zhijun
Published: September 2024

In a severe epidemic such as the COVID-19 pandemic, social distancing can be a vital tool to stop the spread of the disease and save lives. However, social distancing may induce profound negative social or economic impacts as well. How to optimize social distancing is a serious social, political, as well as public health issue yet to be resolved. This work investigates social distancing with a focus on how every individual reacts to an epidemic, what role he/she plays in social distancing, and how every individual’s decision contributes to the action of the population and vice versa. Social distancing is thus modeled as a population game, where every individual makes decision on how to participate in a set of social activities, some with higher frequencies while others lower or completely avoided, to minimize his/her social contacts with least possible social or economic costs. An optimal distancing strategy is then obtained when the game reaches an equilibrium. The game is simulated with various realistic restraints including (i) when the population is distributed over a social network, and the decision of each individual is made through the interactions with his/her social neighbors; (ii) when the individuals in different social groups such as children vs. adults or the vaccinated vs. unprotected have different distancing preferences; (iii) when leadership plays a role in decision making, with a certain number of leaders making decisions while the rest of the population just follow. The simulation results show how the distancing game is played out in each of these scenarios, reveal the conflicting yet cooperative nature of social distancing, and shed lights on a self-organizing, bottom-up perspective of distancing practices.

Értekezésemben a magyar irodalom egyik terjedelmesebb írói teljesítményének, Krúdy Gyula ifjúkori munkásságának vizsgálatára vállalkoztam. A korpusz 1894–1902-ig terjedő időszakában keletkezett művek szisztematikus elemzésének célja kettős volt. Egyfelől a korai alkotói periódusban született alkotások önértékéről igyekeztem megállapításokat tenni, míg ezzel párhuzamosan az életmű általános vonásaival is próbáltam megtalálni bizonyos kapcsolódási pontokat. Disszertációm elsősorban a vallási jelenségekre összpontosító, a transzcendensre reagáló írások elemzéseiből épült fel. Véleményem szerint a vallástörténet eredményei nagyban hozzájárulhatnak az értelmezés hagyományos kereteinek a kiszélesítéséhez. A Krúdy művekben megfigyelhető spirituális összefüggések szerkezettípusainak és ezek poétikai funkciójának feltérképezése tudniillik mindezidáig elkerülte a recepció figyelmét. Elemzéseimmel többek közt a Krúdy figuráinak mintául szolgáló népi eredetű hiedelemlények megidézésének megfoghatatlanságot implikáló poétikai funkcióira kívántam rámutatni. Alapfeltevésem szerint ugyanis a szétszóródott identitású, folyton változó önazonosságú hősöket létrehozó identifikációs technika sémája a népi hiedelmek változékony, alakváltó figuráiéban is felismerhető. Legfontosabb törekvéseim kétségkívül az útonjáró alakjához kapcsolódtak, amely zsáner az útitárs történetek vagy akár a Szindbád-novellák előképeként már több korai Krúdy-szövegbe is bekerült. Az etnográfiai vagy vallástörténeti szempontú Krúdy-olvasás módszerének kidolgozásán és bemutatásán túl a munka legfőbb tanulság ennek az identifikációs technikának a felismerése volt. Saját eredményemnek tekintem ugyanakkor, hogy rámutattam a Krúdy-oeuvre epikai kultúráját jellemző dimenzióváltások vallásos eredetére, illetve e leírások különféle vallási viselkedésformákat és hiteket összemontázsoló szinkretista jellegére.

Metodą worka próżniowego otrzymano kompozyty na bazie fotoutwardzalnej żywicy poliestrowej, w których część włókna szklanego (3%mas.) w macie szklanej zastąpiono włóknem naturalnym (sizal, konopie i kenaf). Oznaczono właściwości fizyko-chemiczne włókien naturalnych (kąta zwilżania, transmitancja promieniowania UV/VIS). Zbadano wpływ napełniacza hybrydowego na strukturę (SEM) i właściwości mechaniczne kompozytów pod kątem ich zastosowania w systemach rurociągowych. Wprowadzenie włókna naturalnego zmniejszyło sztywność i wytrzymałość na rozciąganie kompozytów. Ze względu na najmniejszy kąt zwilżania dla cieczy polarnych i niepolarnych oraz całkowitą transmitancję promieniowania UV/VIS (425 nm) włókna sizalowego najlepsze właściwości przetwórcze i mechaniczne uzyskano dla laminatów z jego udziałem (wytrzymałość na rozciąganie 257 MPa, moduł sprężystości przy zginaniu: 20.5 GPa).

Profesionalizace českých architektů a stavitelů v 19. století na příkladu generace Josefa Hlávky
Authors: Korbel Tomáš
Published: September 2024

This article aims to contribute to the research of the Bohemian elites of the 19th century, and to treat the hitherto neglected topic of the professional rise of Czech and German Bohemian architects and builders in the 19th century. At this time, because of the state reforms of the educational, administrative, and legal systems, the professional perception and social status of this class also changed. In the introduction, architects and builders are included in the process of the modernisation of the construction industry and are defined on the basis of their relationship to art, engineering, and business. Subsequently, architects and builders are defined as a socioprofessional group that has reached a certain degree of professionalism during this period. Against the background of the formation of a modern system of building and architectural education, law, and administration, individual features of professionalisation are scrutinised by discussing specific cases of architects and builders using the method of the collective biography of elites for researching their social background, education, construction practice, and other public activities. Thus, two levels intersect in the article – the general and the personal. In general, we track the interconnection of civil engineering education, the legal system, and administration throughout the century. The factors of this transformation are examined on the personal examples of four members of the generation of Josef Hlávka (Josef Korel, Josef Niklas, Adolf Siegmund, Karl Schlimp), who were the first graduates of the newly reformed educational system and who entered active professional life during the economic and construction boom of the 1860s. Based on a comparison of their career paths and the degree of their achieved social status, a typology of three different levels of professional careers (regional, provincial, and state architect and builder) is then conceived. At the same time, other related phenomena are observed in the individual cases.

A sustainability analysis of community‐conserved areas in Sabah, Malaysia using Ostrom’s design principles
Authors: Loke V.P.W. , Baul T.K. , Nath T.T.
Published: September 2024

Community‐conserved areas (CCA) have the potential to improve local ecological knowledge, ecosystem services, livelihoods, and biodiversity conservation. This study examined the sustainability and community management structure of two recently established CCAs in Sabah, Malaysia.
Data were gathered using Ostrom’s design principles (ODP), content analysis, and focus group discussions. Both CCAs met all eight ODPs and were sustainably maintained by their communities through the evolution of several endogenous CCA management structures. Land tenure security for
CCA sustainability may be enhanced through formal recognition (ODP‐7), nested enterprises (ODP‐8), and conflict resolution (ODP‐6). The findings reveal that indigenous communities can sustainably manage their natural resources and suggest ways to improve CCA management.
Inclusion of indigenous communities in legal frameworks and CCA management should be fostered in the National Forestry Policy. The concept of CCA can be promoted elsewhere towards conserving natural resources and empowering communities for their wellbeing.
Preparation, characterization, and determination of the therapeutic effects of copper nanoparticles green-formulated by Pistacia atlantica in diabetes-induced cardiac dysfunction in rat

Published: September 2024

The development and creation of innovative therapeutic supplements and medications with extraordinary efficacy for addressing severe diabetes are of utmost importance to both developing and developed nations. A bio-inspired method has been documented for producing copper nanoparticles (CuNPs) using Pistacia atlantica leaf extract as a natural stabilizing agent. This approach is applicable, easy, and environmentally friendly, as it avoids using any toxic or harmful reagents. The CuNPs that were synthesized through biological processes underwent characterization using sophisticated physicochemical methods such as energy-dispersive X-ray spectroscopy, transmission electron microscopy, field emission-scanning electron microscopy, and Fourier-transformed infrared spectroscopy. It is confirmed that CuNPs exhibit a spherical structure, with an average size ranging from approximately 30 to 70 nm. Diabetes was induced in vivo through a fructose-enriched diet combined with streptozotocin. Half the subjects were administered CuNPs (100 µg/kg) via oral gavage. In contrast to the animals that were given regular food, the diabetic animals revealed an increase in serum fasting glucose level and a decrease in glucose tolerance. The administration of CuNPs had a significant impact on reducing glucose intolerance and fasting hyperglycemia. Additionally, it helped alleviate the negative effects of diabetes on cardiac output and work. Furthermore, utilizing CuNPs effectively hindered the rise in cardiac signal transducer and activator of transcription 3-phosphorylation caused by diabetes. The findings from this investigation provide evidence of the therapeutic benefits of CuNPs in mitigating diabetes-induced cardiac dysfunction in rats.
Modeling and 3-D simulation of petroleum coke calcination process: investigation of the effect of main operating variables
Authors: Eghbal Ahmadi Mohammad Hosein , Tayyebi Shokoufe , Mosayebi Amir
Published: September 2024

Coke calcination is a process that involves heating green petroleum coke to purify it and eliminate volatile materials for subsequent processing. Due to the complexity of the rotary kiln used in this process, conducting experimental studies can be challenging and restricted. However, quantitative analyses based on developed models can provide a foundation for optimizing and controlling the process, which can significantly enhance the design efficiency. A three-dimensional simulation model of a rotary calcining kiln for petroleum coke was created using COMSOL Multiphysics in a steady-state mode. This model accounted for all relevant physical and chemical phenomena in the gas stream and coke bed flow, including heat transfer, combustion, and the evolution of volatile matter and coke dust. The mathematical modeling yielded distributions of temperature and mass fractions within the kiln, as well as the velocity field. The results revealed two distinct peak temperatures in the gas phase: 1,780 K near the primary air injection point and 1,605 K near the tertiary air injection points. The findings were analyzed, and the impact of key variables was explored. The simulation data indicated that for every decrease of 10–15 m/s in air flow, the gas peak temperature dropped by approximately 100°. Additionally, an increase in the input oxygen concentration led to enhanced combustion, resulting in higher peak concentrations of CO2. The developed simulation model has proven to be a valuable and promising tool for the design and optimization of petroleum coke rotary kilns.
Analysis of heat mass transfer in a squeezed Carreau nanofluid flow due to a sensor surface with variable thermal conductivity

Published: September 2024

This research offers an advanced investigation into the examination of squeezed flow and heat mass transfer mechanisms of non-Newtonian Carreau dissipative nanofluids across a sensor surface. This analysis takes into consideration both variable thermal conductivity and variable viscosity aspects. It is widely accepted that the phenomenon of viscous dissipation has a significant impact on both the temperature distribution and heat transfer characteristics within nanofluids. Hence, it is being considered here. The governing equations of the problem are formulated using the Carreau model for the non-Newtonian fluid for the nanofluid. The thermal conductivity of the sensor surface is assumed to vary linearly with the temperature. The resulting nonlinear ordinary differential equations are solved numerically using the shooting method. The effects of various parameters such as suction parameter and magnetic parameter on the flow, the solutal characteristics, and thermal characteristics are analyzed. The results show that the slip parameter, the magnetic parameter, and the suction parameter have a significant effect on the flow and thermal fields. The heat transfer rate is improved by the squeezed flow index parameter and the Weissenberg number, but reduced by the power law index parameter and the Eckert number. Ultimately, the precision and reliability of the proposed approach are confirmed by benchmarking our data against previous findings. Understanding how variable viscosity impacts flow characteristics, heat transfer efficiency, and the performance of heat exchangers and cooling systems optimizes the design of nanofluids for efficient thermal systems in practical applications.
Effectiveness of microwave ablation using two simultaneous antennas for liver malignancy treatment
Authors: Bošković Nikola , Radjenović Branislav , Nikolić Srdjan , Radmilović-Radjenović Marija
Published: September 2024

Microwave ablation is becoming an increasingly important minimally invasive procedure that uses dielectric hysteresis to generate heat and destroy cancer cells. Tissue damage depends on the input power, procedure duration, and antenna position. Therefore, one of the essential problems is determining parameters that ensure the destruction of the tumor with the desired margins and minimal damage to the healthy tissue. In addition to experimental methods, computer modeling has been proven to be an effective approach for improving the performance of microwave ablation (MWA). Moreover, since the thermal spread in biological tissue is difficult to measure, the development of a predictive model from procedural planning to execution may have a great impact on patient care. This study focuses on determining the optimal parameters for MWA treatment of liver tumors using two identical parallel-positioned multi-slot coaxial antennas. The simulation results suggest that an input power of 20 W or 15 W per antenna suffices for complete tumor ablation with a sufficient safety margin for 600 and 900 s, respectively. In both cases, the created ablation zones were similar. The ablation zones for 15 W per antenna were more spherical, invading a smaller amount of healthy tissue than those for 20 W per antenna. This study may represent a step forward in planning MWA treatment for individual patients.

This dissertation focuses on the assessment of the efficacy and safety of the abatement of antiplatelet therapy in patients with acute coronary syndrome (ACS). The aim of this thesis was to identify cardio-protective strategies against myocardial ischemia–reperfusion injury, evaluate the impact of dual antiplatelet therapy (DAPT) abatement strategies in patients with percutaneous coronary intervention (PCI) and assess the effectiveness of precision medicine approaches in individualizing P2Y12 de-escalation strategies, such as platelet function testing (PFT) guidance, genetic testing guidance, and uniform de-escalation, for ACS patients undergoing PCI. Three distinct studies were conducted, the initial investigation is based on a literature review, the second study entails a comprehensive meta-analysis of RCTs and the third study is a comprehensive literature review of clinical trials. These studies suggest that: beta-blockers, antiplatelet therapy and glycoprotein IIb/IIIa inhibitors show improvements in myocardial ischemia-reperfusion injury, de-escalation of antiplatelet therapy can reduce bleeding risk without compromising the risk of MACE, mostly monotherapy strategy, and the use of uniform unguided de-escalation is the most effective strategy in reducing bleeding events while maintaining efficacy. However, it is important to consider individual patient factors such as bleeding risk, thromboembolic risk, and patient comorbidities to select the optimal approach for DAPT abatement.

Authors: Kong Chuwei , Zhao Jinli
Published: September 2024

Out-of-school science education is important for students’ emotional outcomes, such as their interest in science. Not all students, however, have access to real outdoor environments for hands-on learning. To address this issue, live streaming technology allows for real-time interaction and video-based instruction, which can enhance students’ interest in science and connect in-school and out-of-school learning. The effects of live streaming programs, however, are not well understood. In this study, we used the experiential learning theory to design and implement an activity on seed dispersal and conservation using live streaming technology at a botanical garden. The combined findings from both quantitative and qualitative data showed that primary school students in the urban area significantly increased their situational interest in science through triggering by question-evoked information gaps and engaging with vicarious interactive experiences based on the live streaming technology, indicating the effectiveness of the live streaming activity in the botanical garden. This case study demonstrates the potential of live streaming technology as a remote strategy to share educational resources beyond traditional classrooms and support high-quality education.

Published: September 2024

Understanding how the process of gene expression can be engineered to biomanufacture proteins for medical, agricultural, and industrial applications provides an opportunity to link basic concepts of molecular biology with applications. Here we present a simple activity that uses commonly available materials to simulate the process by which the bacterium Agrobacterium tumefaciens transfers genes to plants and allows students to visualize the expressed protein of interest.

In brief

We describe a first-of-its-kind audit of LGBTQ+ inclusivity in fertility care providers across the United Kingdom. Despite efforts being made to improve LGBTQ+ inclusion in fertility care, our results paint a picture of widespread gaps in clinical and cultural expertise alongside significant barriers to LGBTQ+ inclusion.

LGBTQ+ patients comprise one of the fastest-growing user demographics in fertility care, yet they remain under-represented in fertility research, practice, and discourse. Existing studies have revealed significant systemic barriers, including cisheteronormativity, discrimination, and gaps in clinical expertise. In this article, we present a checklist of measures that clinics can take to improve LGBTQ+ inclusion in fertility care, co-created with members of the LGBTQ+ community. This checklist focuses on three key areas: cultural competence, clinical considerations, and online presence. The cultural competence criteria encompass inclusive communication practices, a broad understanding of LGBTQ+ healthcare needs, and knowledge of treatment options suitable for LGBTQ+ individuals. Clinical considerations include awareness of alternative examination and gamete collection techniques for transgender and gender diverse patients, the existence of specific clinical pathways for LGBTQ+ patients, and sensitivity to the psychological aspects of fertility care unique to this demographic. The online presence criteria evaluate provider websites for the use of inclusive language and the availability of LGBTQ+-relevant information. The checklist was used as the foundation for an audit of fertility care providers across the UK in early 2024. Our audit identified a widespread lack of LGBTQ+ inclusion, particularly for transgender and gender diverse patients, highlighting deficiencies in clinical knowledge and cultural competence. Our work calls attention to the need for further efforts to understand the barriers to inclusive and competent LGBTQ+ fertility care from both healthcare provider and patient perspectives.
Editorial: Memorias, vivencias y diálogos docentes: La ciudadanía en las prácticas docentes latinoamericanas

In a highly polarised context that highlights the need to promote citizenship education, teachers are at the same time excluded from the curricular question of what to teach. In this dossier “Memories, Experiences and Teacher Dialogues: Citizenship in Latin American Teaching Practices” reiterates the importance of professional teaching knowledge and, within it, the centrality of personal memory in giving meaning to the problems that affect society and that should be discussed with students. By bringing together the theoretical reflections of teachers from different Latin American countries on the basis of experience, we contribute to a trans-border perspective on the treatment of these issues.
Constructos del agua, mercancía y valor
Authors: Bonilla-Bonilla Luis Vidal
Published: September 2024

The work revisits certain categories within social sciences to analyze water through two primary lenses. The first lens views water as a social construct, involving various communal, social, and institutional actors. This perspective has historical roots extending back to the liberal era of the early 20th century and continues through the post-war period of 'developmentalism.' During this time, water resources were seen as a public service managed by municipalities, communities, and, following the establishment of the Sistema Nacional de Acueductos y Alcantarillados (SNAA, known as AyA) in 1961, by a centralized state institution. Secondly, the study examines the transition of water from a 'use value' (satisfying a need) to an 'exchange value.' This analysis employs the concept of 'elasticity' of the commodity, representing a kind of expansive long wave embedded in the international political debates of the sixties and seventies. These debates involved various social movements and American business elites, who perceived the concept of 'free enterprise' as under threat. This resulted in 'authoritarian liberalism,' which has had lasting effects. In the present era, a 'total market' logic prevails, where water markets, transnational corporations, and stock market pricing determine the distribution of this resource on the planet through supply and demand laws.
Variations in Sr, Tl, and V concentrations at copper mining sites based on soil depth, plant species, and plant organ

The concentrations of Sr, Tl, and V in soils and plant organs were evaluated at a copper mining site. These are heavy metals that are extremely dangerous and harmful to human and environmental health and, therefore, are on the ATSDR substance priority list. Within the scope of the study, soil samples were taken from different soil depths in the spoil area, the rehabilitation area where planting was performed and adult trees that were at least 20 years old, and the forest area. Soil samples were taken from the rehabilitation and forest areas where Pinus nigra Arnold., Pinus sylvestris L., and Robinia pseudoacacia L. species grow, and leaf, bark, wood, and root samples were taken from trees in the same areas. The study evaluated variations in heavy metal concentrations in soils based on species and soil depth and in plants based on plant species and organs. The study found that the heavy metal concentrations in soils and plant organs generally varied depending on plant species, while these variations were insignificant depending on soil depth. The highest concentrations by species were generally obtained for Sr in Robinia pseudoacacia and for Tl and V in Pinus nigra.
The Concept of Man in Prose of Marina Palei in the Context of the Discoveries of F. M. Dostoevsky
Authors: Ledneva Daria
Published: September 2024

The article considers the representation of “little man” developed in Russian literary criticism of the 19th century, which reflected in works of Russian writers including modern authors. However, besides the image of “little man” constructed by criticism, Russian writers studied the human nature in their own way. The article pays special attention to the artistic discoveries of F. M. Dostoevsky, who showed the heights and abysses of the inner world of a person, despite his social circumstances. Dostoevsky showed how rich inner world allows a person to rise above everyday life and to resurrect spiritually. Dostoevsky in his works disavows the constitution of the “little man” proposed by Belinsky, shows the forms of opposition to the “smallness” imputed to him, the ability to soar above the social circumstances and, in an existential sense, become a “big man.” In modern Russian literature two ways of the representation of the person’s inner world can be found. The inertial moral descriptive tradition of depicting a little man is preserved, and the principle of depicting the character’s spiritual growth is being developed. The article determines the artistic features of the image of the person’s inner world in the surrounding social and domestic circumstances in the work of Marina Palei and correlates them with the artistic discoveries of F. M. Dostoevsky on the grounds of artistic continuity and development in terms of specific historical modifications. The article also examines how Dostoevsky represent St. Petersburg. The works of Dostoevsky of the 1870s present the images of the disastrous existence of Petersburg, and Palei’s prose aggravates the image of gloomy and stuffy Petersburg and presents a sick and dying city, which death is inevitable; everyday life and life in general of a person proceeds with the triumph of vulgarity and meanness. The rich inner world of the characters is already powerless to soar above vulgarity or overcome it, as it was in Dostoevsky's works. The characters of Marina Palei have enough courage and fortitude only to dream of breaking into an ideal world, or at least into a dream, replacing the real world with them. But, from an existential point of view, the character of Marina Palei, like the character of Dostoevsky, retains his self-awareness as a Man (with a capital letter), in the social circumstances of a little man looking for a way out of predestination.
The Problem of Genre Completion in “White Nights,” a Novel by F. M. Dostoevsky
Authors: Batalova Tamara
Published: September 2024

The article substantiates the necessity of using the “genre completion” category developed by P. N. Medvedev in the analysis of a work of art. “White Nights” is successively connected with the “Petersburg Chronicle” by F. M. Dostoevsky. This relationship is rooted in the proximity of the time of creation, linguistic and poetic techniques, and thoughts. The multifaceted relationship of the “White Nights” with the “Petersburg Chronicle” helps to understand the fundamental concept of the “sentimental novel.” Analyzing the symbolism of rhyming plot situations, images, details in the text (“web,” “yellow,” “lonely,” “Matryona,” etc.), numbers (8, 26, 15), the meaning of which is amplified and revealed in the epilogue, the author of the article comes to the conclusion that in “White Nights” the main idea of the work is artistically completed. This explains the mental crisis of the hero caused by the tragedy of reverie. Nastenka’s faithfulness in love helps the Dreamer to strengthen his faith in ideals. According to the type of genre completion, “White Nights” by F. M. Dostoevsky is a novel, which corresponds to the author’s concept of the work. There are two plot / composition levels in the novel and one completion for both. The author of the article proves that the analysis of the novel “White Nights” reveals the need to use the principles of P. N. Medvedev’s sociological poetics.
