Performative Discourse in E. Grishkovets Monodramas
Authors: Ageeva Natalia
Published: August 2023

The purpose of the study is to determine the specifics of the compositional–speech form of E. Grishkovets' monodrama. The subject of the study is the ratio of narrative and anarrative elements in six monodramas by E. Grishkovets - "How I ate a dog", "Simultaneously", "Dreadnoughts", "+1", "Farewell to paper", "Whisper of the heart". To achieve this goal, the following tasks are solved: firstly, to identify and characterize the anarrative elements in the monodramas of E. Grishkovets; secondly, to analyze the communicative situations underlying the action of the studied plays; thirdly, to determine the ratio of narrative and performative elements in the works. The theoretical basis was the work in the field of artistic discourse: the theory of the dialogical nature of art by M. M. Bakhtin, which has already become a classic, and was developed in the research of V. I. Tyupa. The main method of research was the discursive analysis of the literary text, which allows to identify and describe the invariant model of E. Grishkovets' monodrama. The scientific novelty of the research lies in the approach used: the invariant structure of E. Grishkovets' monodramas is revealed by studying the genre through discourse. The analysis of the peculiarities of the discourse of E. Grishkovets' monodramas showed that the event of each of the plays consists in the explication "here and now" before the reader/viewer of complex internal processes occurring in the minds of the characters asking ontological questions related to the self-determination of a person in the world. The human essence in one aspect or another of being becomes a communicative object, while the hero tries to clarify his status for himself and the addressee of his speech. At the same time, in the picture of the hero's world, understanding turns out to be more significant than gaining knowledge. Trying to clarify for himself and the addressee one of the general laws of existence, the hero simultaneously transforms his own consciousness, since he comes to the conclusion that it is impossible to achieve mutual understanding in its entirety.
Stalin's Houses on Lenin Street: Late Soviet Underground Rock in Patriotic Discourse (1981-1991)
Authors: Osipov Sergey
Published: August 2023

The subject of the study is the late Soviet underground rock song both in the general context of Soviet popular culture and in the context of patriotic discourse in the Soviet popular song of the 1960s-1980s. The correlation of various segments of Soviet popular music and their access to mass communication media, the phenomenon of the transformation of rock music from a marginal subculture into one of the segments of popular Soviet song is considered. Concrete examples demonstrate the content versatility of an uncensored Soviet rock song, in particular, its contribution to patriotic discourse. The duration and stability of the existence of the considered variations of patriotic discourse are considered. The main conclusions of the study include: -the development of mass/popular songs is directly dependent on the development of mass communication and access to them; -in the 1960s-1980s, the Soviet state lost its monopoly on the ownership of means of delivering music content to the listener; - by the early 1980s Soviet rock music ceased to be a copy of the Western model and became a Soviet/Russian song genre based on domestic melodics, Russian literary poetic tradition, etc.; -the access to the means of delivering song content turned rock song into a segment of Soviet popular music, both censored and in uncensored versions; -the socio-political content in general and the patriotic theme in particular were not an attribute exclusively of the official Soviet song, but found their expression in the work of the authors of the underground rock scene; - the Soviet popular uncensored song made the patriotic discourse much more diverse, rich, sharp, etc. - the identified interpretations of patriotic discourse have a stable existence, being actualized in the modern media environment.

The impact of the disease symptoms was assessed using TSIDAV vignette and the main research was followed by the analysis related to the cultural impact on the results. The cultural impact analysis was based on Hofstede’s national culture model. 49 Ukrainian and 61 Polish patients participated. Mean Ukrainian TSIDAV value was 0.31 (SD 0.83). Gender values ranged <0 to -1.0, and according to the key for results interpretation it confirmed high disease impact on daily activities. Higher disease impact among men than among women (mean TSIDAV value 0.18, SD 0.95; and 0.44, SD 0.69 respectively). Mean Polish TDSIDAV value was 0.68 (SD 0.69). Among Polish women mean value was -0.85 (SD 0.54), within men mean -0.35 (SD 0.83). Applying G. Hofstede’s cultural model Ukrainian Power Distance score 92 reflects power holders societal distance. Low scores of Individualism and Masculinity dimensions. Uncertainty avoidance score 95, meaning feeling threatened by ambiguous situations. Long term orientation dimension score 86 reflects Ukrainian society pragmatism. Polish results shown hierarchical (scoring 68), individualist (score 60), masculine society (score 64). Avoidance dimension scores 93 in Poland, meaning avoiding uncertainty preference. Long Term Orientation dimension scored 38, defining more normative than pragmatic society.
Dual-Band MIMO Antenna with Four CPW Elements using Polarization Diversity for 5G Mobile Communication Networks and Satellite
Authors: El Hadri D. , Zugari A. , Zakriti A. , El Ouahabi M.
Published: August 2023

In this paper, a novel design of compact quad-element MIMO (Multiple Input Multiple Output) antenna for 5G communication networks and satellites is proposed. The four similar elements of this antenna are placed perpendicularly to each other on a 40x40 mm2 FR4 substrate. Each element is fed by a CPW (coplanar waveguide) line. Two slits and an I-shaped slot are etched into the patch, and by varying their parameters; a good matching is achieved in the lower (4.9 GHz) and upper (17 GHz) frequency bands. However, 25 and 30 dB isolations are attained in the lower and upper bands, using the polarization diversity technique and adding stubs on the ground plane. A prototype of the proposed antenna is fabricated and measured. Moreover, the performance of the MIMO antenna is studied in terms of ECC (envelope correlation coefficient), DG (diversity gain), TARC (total active reflection coefficient), realized gain, efficiency, and radiation pattern, validated with the measured results, and showed a good agreement.
New hybrid segmentation algorithm: UNet-GOA
Authors: Yousefi Tohid , Aktaş Özlem
Published: August 2023

The U-Net architecture is a prominent technique for image segmentation. However, a significant challenge in utilizing this algorithm is the selection of appropriate hyperparameters. In this study, we aimed to address this issue using an evolutionary approach. We conducted experiments on four different geometric datasets (triangle, kite, parallelogram, and square), with 1,000 training samples and 200 test samples. Initially, we performed image segmentation without the evolutionary approach, manually adjusting the U-Net hyperparameters. The average accuracy rates for the geometric images were 0.94463, 0.96289, 0.96962, and 0.93971, respectively. Subsequently, we proposed a hybrid version of the U-Net architecture, incorporating the Grasshopper Optimization Algorithm (GOA) for an evolutionary approach. This method automatically discovered the optimal hyperparameters, resulting in improved image segmentation performance. The average accuracy rates achieved by the proposed method were 0.99418, 0.99673, 0.99143, and 0.99946, respectively, for the geometric images. Comparative analysis revealed that the proposed UNet-GOA approach outperformed the traditional U-Net architecture, yielding higher accuracy rates.
Bighorn sheep associations: understanding tradeoffs of sociality and implications for disease transmission
Authors: Tosa Marie I. , Biel Mark J. , Graves Tabitha A.
Published: August 2023

Sociality directly influences mating success, survival rates, and disease, but ultimately likely evolved for its fitness benefits in a challenging environment. The tradeoffs between the costs and benefits of sociality can operate at multiple scales, resulting in different interpretations of animal behavior. We investigated the influence of intrinsic (e.g., relatedness, age) and extrinsic factors (e.g., land cover type, season) on direct contact (simultaneous GPS locations ≤ 25 m) rates of bighorn sheep (Ovis canadensis) at multiple scales near the Waterton-Glacier International Peace Park. During 2002–2012, male and female bighorn were equipped with GPS collars. Indirect contact (GPS locations ≤ 25 m regardless of time) networks identified two major breaks whereas direct contact networks identified an additional barrier in the population, all of which corresponded with prior disease exposure metrics. More direct contacts occurred between same-sex dyads than female-male dyads and between bighorn groups with overlapping summer home ranges. Direct contacts occurred most often during the winter-spring season when bighorn traveled at low speeds and when an adequate number of bighorn were collared in the area. Direct contact probabilities for all dyad types were inversely related to habitat quality, and differences in contact probability were driven by variables related to survival such as terrain ruggedness, distance to escape terrain, and canopy cover. We provide evidence that probabilities of association are higher when there is greater predation risk and that contact analysis provides valuable information for understanding fitness tradeoffs of sociality and disease transmission potential.

Working donkeys (Equus asinus) support human living standards globally. However, there is little information on the effect of human perceptions of emotion and pain on the welfare of working donkeys. We interviewed donkey owners (n = 332) in Pakistan to determine the relationship between human perspectives on donkey sentience: emotions and the ability to feel pain, and the routine working practices that could impact donkey welfare. The majority of donkey owners used padding under the saddle (n = 211; 63.6%; 95% CI (58.3%–68.9%)) and provided access to food (n = 213; 64.2%; 95% CI (58.9%–69.3%)) and water (n = 195; 58.7%; 95% CI (53.4%–64.1%)) during the working day. Owners reported that at some point in their donkey’s life, 65.3% (95% CI (60.2%–70.5%)) had load-associated injuries, of which 27.7% (n = 92; 95% CI (22.8%–32.5%)) were wounds, 20.5% (n = 68; 95% CI (16.1%–24.8%)) were lameness and 7.2% (n = 24; 95% CI 4.4%–10.0%) were back pain. In total, 81.3% (95% CI 77.1%–85.5%; n = 270) of owners believed that their donkeys felt pain, and 70.2% (95% CI (65.2%–75.1%; n = 233) of owners believed that their donkeys had emotions. Multiple correspondence analysis (MCA) was used to understand the relationship between owners’ recognition of emotions and pain in donkeys and their working practices. The MCA factor map revealed two clusters, named positive and negative clusters. The positive cluster included owner’s recognition of donkey pain and emotions, the availability of food and water, use of padding under the saddle, absence of injuries along with the willingness to follow loading guidelines. The negative cluster represented practices that did not benefit donkey welfare, such as using saddles without padding and a lack of food and water during work. The presence of injuries, owners not recognizing that donkeys feel pain and emotion along with an unwillingness to follow loading guidelines were also found in the negative cluster. We show that the owners who recognized sentience in their donkeys were more likely to use practices that are good for donkey welfare. The ability of owners to identify sentience in donkeys, along with their willingness to follow welfare guidelines, are important factors in improving the lives of working donkeys.

En el presente trabajo se evalúa el proceso de restauración ambiental que se desarrolla en un ex basural a cielo abierto (Cuenca Matanza-Riachuelo, Municipio de Marcos Paz, Buenos Aires, Argentina) mediante la utilización de indicadores biológicos. Los indicadores biológicos elegidos fueron comunidades vegetales, de anuros y de coleópteros edáficos pertenecientes a dos familias Carabidae y Aphodiidae. Los sitios de muestreo fueron seleccionados teniendo en cuenta la variabilidad del predio y su perfil topográfico. El muestreo de vegetación se realizó con 8 parcelas de seguimiento continuo (Invierno; primavera; verano) estimando la cobertura por especie y siguiendo la metodología de Braun-Blanquet. Se relevó la comunidad de anuros mediante dos metodologías: visual y auditiva. La captura de los coleópteros fue mediante la colocación de trampas de caída. Anuros y coleópteros fueron muestreados en primavera y verano. Se identificaron un total de 52 especies vegetales. Se observaron diferencias significativas en la diversidad entre estaciones, siendo más alta en invierno y menor en primavera y verano. Se detectaron un total de 5 especies de anuros. El número de especies presentes durante ambas estaciones fue similar, aunque variaron su identidad. Se identificaron un total de 6 especies pertenecientes a la familia Carabidae y una a la familia Aphodiidae. La diversidad y la riqueza mostraron diferencias significativas entre las estaciones, siendo mayores ambos valores durante primavera. El elenco de especies presentes evidencia un proceso de sucesión en sus estadios tempranos para todos los indicadores biológicos estudiados, aunque el tiempo de restauración es relativamente corto.

Published: August 2023

Entender cómo se distribuye la biodiversidad terrestre y los tipos de vegetación en relación con el clima es fundamental en ecología. Se han desarrollado diversos sistemas bioclimáticos para clasificar las zonas de vida del planeta. Entre ellos, el sistema de clasificación bioclimática global de Rivas-Martínez permite categorizar el territorio en pisos bioclimáticos a partir de variables climáticas. De este modo, los continuos climáticos se expresan como categorías discretas que resultan útiles para hacer inferencias sobre las comunidades ecológicas y el funcionamiento de los ecosistemas. Sin embargo, la distribución de los pisos bioclimáticos no está disponible ni completamente ni de forma unificada para el conjunto de la Cuenca Mediterránea, un punto caliente de biodiversidad con gran amplitud bioclimática. En el presente trabajo, hemos solventado este vacío de información siguiendo las reglas del sistema de clasificación bioclimática global de Rivas-Martínez para generar un mapa de pisos bioclimáticos de toda la Cuenca Mediterránea, a una resolución de 30 segundos (~ 1 km). Para ello, hemos utilizado las bases de datos de temperatura de WorldClim y el software R como Sistema de Información Geográfica (SIG) para operar con las capas ráster de interés (índices de temperatura positiva, de continentalidad, de termicidad, y de termicidad compensado). El código R y las capas bioclimáticas resultantes están disponibles tanto en formato vectorial como ráster en un repositorio de acceso abierto.

Published: August 2023

Introduction: The classical surgical treatment of Hirschsprung’s Disease (HD) is by resection of the aganglionic segment of the distal intestine and bringing down the ganglionic segment by Modified Duhamel’s procedure or other pull-through operations. The assessment of the postoperative functional outcome and continence scoring systems are important considerations during follow-up of these children. In the present study, a scoring system was used to analyse the postoperative functional outcome of HD as there are very few studies, that have objectively assessed the same. Aim: To assess the functional outcome in children under six years of age, who underwent Modified Duhamel’s procedure for HD. Materials and Methods: This descriptive longitudinal, study was conducted in the Tertiary Teaching Institution at Government Medical College, Thiruvananthapuram, Kerala, India. The duration of the study was one year and nine months, from February 2017 to November 2018. Forty cases of biopsy proven HD, who underwent Modified Duhamel’s procedure were analysed. Postoperative follow-up was done at one, two, and three years after the definitive surgical procedure. Patients were classified as good, fair and poor outcome groups depending based on the Taylor-Duthies-Zachary continence scoring system. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 22.0. Pretest comparison of scores and p-value were analysed by Wilcoxon signed-rank test. A p-value <0.05 was considered as statistically significant. Results: The mean age of the study participants was 12.7±4.1 months and age ranges from three to 25 months. Median stool frequency per day after one, two, and three years of surgery, was 6.0, 4.0, and 3.0, respectively. The observed difference in median frequency between one and two year, one and three, and two year and three year was statistically significant (p<0.05). Median continence score to assess the anal sphincter control at one, two and three years after surgery were 2.3, 4.0 and 4.5, respectively. The observed difference in scores over successive years, was statistically significant (p<0.05). Conclusion: The functional outcome in patients, who underwent Duhamel’s procedure was good and the postoperative issues like increased stool frequency, and sphincter control improved over successive years.

Published: August 2023

Introduction: Robotics (R) is concerned with the linkage between perception and action, and Artificial Intelligence (AI) plays a significant role in enabling this intelligent relationship. In dentistry, AI has primarily been utilized to enhance diagnostic procedures, which are crucial for achieving favorable treatment outcomes and providing excellent patient care. Aim: The aim of this cross-sectional study was to assess the Knowledge, Attitude, and Perception (KAP) of dentists towards R and AI in oral health and preventive dentistry. Materials and Methods: The study was conducted at the Department of Public Health Dentistry, Yenepoya Dental College, Mangalore, Karnataka, India. The duration of the study was three months, from March 2022 to June 2022. A closed-ended, self-administered questionnaire using Google Forms was distributed among 161 dental professionals in South India. The questionnaire included items related to KAP towards the use of R and AI in preventive dentistry and oral health. Descriptive analysis was performed, and oneway Analysis of Variance (ANOVA) was used to compare mean values. Tukey’s post-hoc test was employed for group comparisons. Results: The mean age of the participants was 30.17±9.18 years. Out of the 161 participants (70 males and 91 females), 133 (82.6%) had heard about R and AI in dentistry, but only 78 (48.4%) were aware of the differences between R and AI. Among the dentists, 74 (46%) believed that AI might have a future in India, and 145 (90.6%) responded that R and AI were useful during the COVID-19 pandemic. Additionally, 97 (60.6%) participants expressed willingness to be treated by R and AI if necessary, and 107 (66.9%) would prefer to receive lectures or workshops from a robot. Tukey’s post-hoc test revealed that the staff’s knowledge and attitude were significantly higher than those of interns, postgraduates, and private practitioners (p<0.05). Conclusion: The findings of this study indicate that the majority of dentists have a negative perception of R and AI. Despite having a generally positive attitude, dentists have limited to no utilization and application of R and AI. It is crucial to raise awareness of this concept in the near future, as it has the potential to enhance treatment effectiveness and efficiency.

Shoot Culture of Ocimum sp. and Its Phytochemical Profile
Authors: Mastuti R. , Munawarti A. , Siswanto D.
Published: August 2023

The success of the in vitro culture technique is influenced by many factors, including the type of explants, culture medium and exogenous plant growth regulators (PGR). These factors greatly influence the speed and effectiveness of plant regeneration as well as the profile of the phytochemical compounds produced. Therefore, this study aims to determine the effect of the PGR combination on the growth response of in vitro node explants as well as the phytochemical profiles of Ocimum sp. Node explants obtained from 2 weeks old in vitro seedlings were cultured on MS medium with the addition of PGR, namely BAP and Kinetin (0.2 and 5 mg/l) combined with NAA (0.1 and 0.2 mg/l) and synthetic cytokinins alone namely Thidiazuron (TDZ) (1, 3, and 5 mg/l). The growth response of the explants and the potential for regeneration were observed for 8 weeks of culture. Effects of adding activated charcoal (AC) to root media were observed on growth of plantlets aged 2 weeks. Phytochemical profile of In vitro shoot was analyzed using GC-MS and LC-MS to be compared with its profile in in vitro callus tissue. The results showed that MS medium with the addition of a combination of cytokinin and auxin was able to induce shoot regeneration in node explants of Ocimum sp. in vitro. The Kinetin/NAA combination produced better shoot height growth, while the BAP/NAA combination produced a higher leaves number. Thidiazuron at all concentrations was able to induce shoots that were more likely to form rosettes. The addition of AC to the rooting medium did not have a positive effect on the response of shoot and plantlet growth. Chromatographic screening showed different profiles of secondary compounds in the callus and shoot tissues of Ocimum sp. in vitro. Callus composed of actively dividing cells do not produce some of the secondary compounds as produced by in vitro shoots. This shows the difference in the potential of cells or tissues in synthesizing secondary metabolites.
Pigeon Pea (Cajanus cajan L.) Based Intercropping System: A Review
Authors: Kushwaha Ayushi , Mehta Chandra Mohan
Published: August 2023

Pigeon pea (Cajanus cajan L.) is a tropical and subtropical leguminous crop it is rich in protein and has high nutrient content and India is the largest producer. Pigeon pea is grown in a sole cropping system as well as with intercropping system it is majorly intercropped with legumes, cereal, and oilseed crops. Intercropping depends upon the interaction of crop species and their management. Intercropping is done between different types of cereals, pulses, and oilseed crops. Some successful cereal and pulse intercropping systems like (mung bean + maize) where, a larger equivalent yield is obtained by seeding maize following four rows of mung beans than by closer spacing. Wheat is mostly intercropped with chickpea, mustard and barley but in irrigated conditions when wheat intercropped with mustard proved more profitable than wheat intercropped with chickpea. In the Mediterranean nation, common vetch (Vicia sativa) is popularly grown with cereals. When maize and cowpea were intercropped in southern Africa, the quantity of nitrogen, phosphate, and potassium in the soil was enhanced. Maize and beans are popular in eastern Africa. However, there are many challenges while adopting intercropping for the survival of the plant. In intercropping of pigeon pea when two or more than crops are sown, they show a synergetic effect, and when it is treated with the biofertilizers like Rhizobium, arbuscular mycorrhizal fungi (AMF), phosphate-solubilizing microorganisms (PSM) and plant growth-promoting rhizobacteria (PGPR), it enhances the growth of the plant, fixes atmospheric nitrogen in the soil, availability of phosphorus to the plant increases the uptake of other micro-nutrient to the plant and plant beneficial microbes. When dual inoculation of Rhizobium and AMF is done, chlorophyll content increases in the plant.

Published: August 2023

Photothermal superhydrophobic surfaces are potential to become ideal anti‐/deicing surfaces due to their rapid water removal, icing delay, and photothermal deicing performance. Here, a robust photothermal icephobic surface with mechanical durability is shown that is integrated with a microspine array inspired by honeycomb and cactus thorn (i.e., MAHC), which is developed by a laser‐layered microfabrication strategy. The maximum stress on the microspine of the MAHC is reduced by ≈2/3, due to the protection of the bionic honeycomb structure. Even after 200 linear abrasions by a steel blade, the MAHC remains superior water repellency with a water contact angle of 150.7° and roll‐off angles of 10.3°, stable icing delay time (578.2 s), and rapidly photothermal deicing capabilities (401 s). As the MAHC is fabricated on a curvature surface such as a copper alloy transmission line for an overhead high‐speed rail, a stable photothermal anti‐/deicing in a low‐temperature environment still can be achieved effectively. The freezing rain covering the functional transmission line completely slides off within 758 s under one sun illumination. This studying offers insight into the design of novel materials with stable anti‐icing/icephobic structures, which would be extended into some applied realms, for example, transportation fields or power systems in cold or low‐temperature climates.
Nation: A New Dimension of Literary Criticism in the Context of Globalization
Authors: Hu Yamin
Published: August 2023

Based on the discrimination of the nation and its related concepts, this chapter makes it clear that the unified, multi-ethnic Chinese nation varies from the Western concept of nation, and that the concept of nation in Chinese form refers specifically to the Chinese nation. Marxist classical writers’ arguments on the nation are analyzed concretely. In the Chinese form, the nation is never about self-seclusion, nor about going back to the good old days, and by no means implies the collective’s suppression of its individual members. The nation, as an embodiment of the social relations of group identity formulated over the course of history, is a historical existence. The core of a nation is its culture. Cultural identity is the foundation for the existence of a nation. The absence of culture and national memory could foretell the extinction of a nation. The correlation between the nation and the people is reflected in that the people are the subject of the nation and the liberation of the people is tantamount to the liberation of the nation. For the first time, the nation is introduced into the Chinese form as a critical dimension with core metrics of national identity and national spirit.
A Study of Value Judgment
Authors: Hu Yamin
Published: August 2023

The insistence to the value judgment is both an innate mission of Marxist literary criticism and a necessity for the social and cultural construction of contemporary China and the world. The reconstruction of value judgment is theoretically based on the social ideals of Marx and Engels on full emancipation of human beings, and the value judgment in the Chinese form is designed from three basic dimensions, namely the human, social, and aesthetic dimensions. The human dimension emphasizes that the critics should regard the respect for human life, the maintenance of human dignity, and the pursuit of justice as their bottom line. The relativity and the paradox of literary values are explored respectively from historical and practical perspectives. The construction of a dominant as well as compatible system of value judgment provides a new value judgment reference for contemporary Chinese literary criticism and the global literary world.
Near-extremal Freudenthal duality
Authors: Chattopadhyay Arghya , Mandal Taniya , Marrani Alessio
Published: August 2023

Abstract

Freudenthal duality is, as of now, the unique non-linear map on electric-magnetic (e.m.) charges which is a symmetry of the Bekenstein-Hawking entropy of extremal black holes, displaying the Attractor Mechanism (possibly, up to some flat directions) in Maxwell-Einstein-scalar theories in four space-time dimensions and with non-trivial symplectic e.m. duality. In this paper, we put forward an effective approach to a consistent generalization of Freudenthal duality to near-extremal black holes, whose entropy is obtained within a Jackiw-Teitelboim gravity upon dimensional reduction. We name such a generalization near-extremal Freudenthal duality. Upon such a duality, two near-extremal black holes with two different (and both small) temperatures have the same entropy when their e.m. charges are related by a Freudenthal transformation. By exploiting Descartes’ rule of signs as well as Sturm’s Theorem, we show that our formulation of the near-extremal Freudenthal duality is analytical and unique.

Published: August 2023

Abstract

We analyse the single top production in association with the Higgs at the Large Hadron Collider (LHC) using Standard Model (SM) effective operators upto dimension six. We show that the presence of effective operators can significantly alter the existing bound on the top-Higgs Yukawa coupling. We analyse events at the LHC with 35.9 and 137(140) fb−1 integrated luminosities using both cut-based and machine learning techniques to probe new physics (NP) scale and operator coefficients addressing relevant SM background reduction. The four fermi effective operator(s) that contribute to the signal, turn out to be crucial and a limit on the top-Higgs Yukawa interaction in presence of them is obtained from the present data and for future sensitivities.

Time-weighted estimates for the Blackstock equation in nonlinear ultrasonics
Authors: Nikolić Vanja , Said-Houari Belkacem
Published: August 2023

High frequencies at which ultrasonic waves travel give rise to nonlinear phenomena. In thermoviscous fluids, these are captured by Blackstock’s acoustic wave equation with strong damping. We revisit in this work its well-posedness analysis. By exploiting the parabolic-like character of this equation due to strong dissipation, we construct a time-weighted energy framework for investigating its local solvability. In this manner, we obtain the small-data well-posedness on bounded domains under less restrictive regularity assumptions on the initial conditions compared to the known results. Furthermore, we prove that such initial boundary-value problems for the Blackstock equation are globally solvable and that their solution decays exponentially fast to the steady state.
Outcomes of pessary fitting trials for patients with stage IV pelvic organ prolapse: a prospective study
Authors: Zhou Ying , Sun Tianshu , Ju Aijing , Zhu Lan
Published: August 2023

Introduction and hypothesis

The objective was to evaluate the efficacy of pessaries in the treatment of stage IV pelvic organ prolapse (POP) and identify the influencing factors.

Methods

One hundred and fifty-seven patients with stage IV symptomatic POP were admitted to the hospital for pessary fitting. A successful pessary fitting was defined as a patient fitted with a pessary at the initial fitting in whom use continued 2 weeks later. The rates of successful pessary fitting, patient satisfaction, remission of prolapse and urinary symptoms, and the occurrence of factors associated with successful pessary fitting were calculated and predictors of appropriate pessary type selection were analyzed.

Results

A total of 130 patients with stage IV POP had a successful pessary fitting (82.8%). The satisfaction rate associated with the two types of pessaries was more than 90%. The success rate among patients undergoing a ring pessary fitting trial was 44.6%, and 84.3% of the patients were self-managed. Prolapse symptoms significantly improved in 90% of cases, and urinary symptoms improved in 58–93% of cases from baseline. The number of vaginal deliveries, history of hysterectomy and vaginal introitus/total vaginal length (TVL) ratio were independent risk factors associated with unsuccessful pessary fitting.

Conclusion

For patients with stage IV POP, the successful fitting rate is as high as 80% or more. More vaginal deliveries, a history of hysterectomy, and a larger vaginal introitus/TVL ratio (ratio  >0.6) were predictors of unsuccessful pessary fitting.
[18F] AlF‑NOTA‑FAPI‑04 PET/CT as a promising tool for imaging fibroblast activation protein in gastrointestinal system cancers: a prospective investigation of comparative analysis with 18F-FDG
Authors: Yang Liping , Xu Shichuan , Cheng Liang , Gao Chao , Cao Shaodong , Chang Zhengsong , Wang Kezheng
Published: August 2023

Purpose

The radiopharmaceutical [18F]AlF-NOTA-FAPI-04 presents a promising alternative to 68 Ga-FAPI owing to its relatively longer half-life. This study aimed to evaluate the clinical usefulness of [18F]AlF-NOTA-FAPI-04 PET/CT for the diagnosis of primary and metastatic lesions in various types of gastrointestinal system cancers, compared with 18F-FDG PET/CT.

Methods

Patients diagnosed with gastrointestinal system malignancies were prospectively enrolled. All patients underwent both 18F-FDG and 18F-FAPI-04 PET/CT scans within one week, with 44 (73.3%) for cancer staging and 16 (26.7%) for tumor restaging. Diagnostic efficacy of the primary tumor, as well as the presence and number of lymph nodes and distant metastases, were assessed. Tumor uptake was quantified by the maximum standard uptake value (SUVmax).

Results

For detection of primary tumor, the diagnostic sensitivity of 18F-FDG PET/CT was 72.7%, while it was 97.7% for 18F-FAPI-04 PET/CT. Based on per-lymph node analysis, the sensitivity, specificity, and accuracy of 18F-FAPI-04 PET/CT in diagnosing metastatic lymph nodes were 91.89%, 92.00%, and 91.96%, respectively. These values were notably higher than those 18F-FDG PET/CT (79.72%, 81.33% and 80.80%, respectively). The 18F-FAPI-04 PET/CT surpassed 18F-FDG PET/CT in detecting suspected metastases in the brain (7 vs. 3), liver (39 vs. 20), bone (79 vs. 51), lung (11 vs. 4), and peritoneal carcinoma (48 vs. 22). Based on per-patient analysis, differential diagnostic accuracies (18F-FAPI-04 vs. 18F-FDG PET/CT) were observed in all patients (91.7% vs. 76.7%), the initial staging group (90.9% vs. 79.5%), and the re-staging group (93.8% vs. 68.7%). Additionally, 18F-FAPI-04 PET/CT revised final diagnosis in 31.7% of patients, contrasting with 18F-FDG PET/CT, and prompted changes in clinical management for 21.7% of the patients.

Conclusion

18F-FAPI-04 PET/CT outperforms 18F-FDG PET/CT in delineating the primary gastrointestinal tumors and detecting suspected metastatic lesions due to a higher target-to-background ratio (TBR). Moreover, 18F-FAPI-04 PET/CT could provide valuable guidance for tumor staging, thereby having a potential impact on patient management.
“Single-use peripheral” vs “conventional” reaming in total hip arthroplasty: how to respect native centre of rotation and acetabular offset? A CT study
Authors: Viglietta Edoardo , Previ Leonardo , Giuliani Veronica , Rescigno Giulia , Gugliotta Yuri , Redler Andrea , Iorio Raffaele
Published: August 2023

Purpose

The respect of native hip offset represents a mainstay for satisfying results in total hip arthroplasty (THA). Historically, a great interest has been focused on restoration of femoral offset, while only in recent years, acetabular offset (AO) has been considered. The purpose of the current study was to compare the “single-use peripheral” reaming technique with the “conventional” one for the maintenance of the native COR of the hip and AO in patients undergoing to primary THA.

Methods

Eighty patients affected from primary hip osteoarthritis were prospectively enrolled in the study and were divided in two groups (Group A “single-use peripheral” and Group B “conventional” reaming technique). Pre- and post-operatively, AO, acetabular floor distance (AFd) and acetabular version (AV) were assessed through a CT scan. A comparison between groups for the radiological parameters, surgical time and complications was performed.

Results

The demographic data were similar in both groups. The complications rate and the AV did not differ statistically between groups. Group A presented a statistically significant shorter surgical time and lower variation between pre- and post-operative AO and AFd. Statistical significance was defined as p < 0.05.

Conclusions

The “single-use peripheral” reaming technique demonstrated to be more reliable in reproducing the native COR and AO of patients undergoing to primary THA than the “conventional” one. The operative time was significantly reduced, and it may lead to a reduction in the infection risk even though it was not observed in the current study. Further research could be useful to validate such findings and to assess clinical impact and long-term survival of the implant.

Published: August 2023

Purpose

Cadaver dissections and X-ray based 3D angiography are considered gold standards for studying neurovascular anatomy. We sought to develop a model that utilize the combination of both these techniques to improve current tools for anatomical research, teaching and preoperative surgical planning, particularly addressing the venous system of the brain.

Materials and methods

Seven ethanol-fixed human cadaveric heads and one arm were injected with a latex-barium mixture into the internal jugular veins and the brachial artery. After the ethanol-based fixation, specimens were scanned by high-resolution cone-beam CT and images were post-processed on a 3D-workstation. Subsequent, microsurgical dissections were performed by an experienced neurosurgeon and venous anatomy was compared with relevant 3D venograms.

Results

Latex-barium mixtures resulted in a homogenous cast with filling of the cerebral venous structures down to 150 μm in diameter. The ethanol-based preparation of the cadaveric brains allowed for near-realistic microsurgical maneuverability during dissection. The model improves assessment of the venous system for anatomical education and hands-on surgical training.

Conclusion

To our knowledge we describe the first preparation method which combines near-realistic microsurgical dissection of human heads with high-resolution 3D imaging of the cerebral venous system in the same specimens.
Environmental drivers of eukaryotic plankton and fish biodiversity in an Arctic fjord

Published: August 2023

Arctic fjords are experiencing rapid environmental shifts due to climate change, which may have significant impacts on marine biodiversity and ecosystem functioning. However, the impact of climate change on fjord biodiversity is difficult to quantify given the low accessibility and high cost to sample these areas. In this study, we sampled locations from inside to outside an Arctic fjord and used environmental DNA metabarcoding to assess how the biodiversity of fish and eukaryotic plankton communities relate with environmental conditions. We detected a total of 12 fish taxa and 872 MOTUs for eukaryotes and found marked gradients of temperature and salinity driven by the distance to the glacier at the terminal part of the fjord and depth. Eukaryotic richness was mainly associated with lower temperature and chlorophyll a. Moreover, co-inertia analyses showed a shared structure between eukaryotes assemblages and the environmental gradients. A partial association between eukaryote and fishes suggest a potential shared effect of environmental gradients among these taxa. Our findings provide a baseline for future studies to assess how these assemblages may be impacted by ongoing environmental changes and highlight how fjord ice loss and warming might shift environmental gradients and species distribution under climate change.
