Authors: Sharma Vijay K , Divyashree GN , Preeti  , Ambiya Vikas , Kumar Ashok , Khullar Srishti , Rana Vipin 
Published: September 2024

Purpose:
To describe the role of wavefront-guided pupilloplasty in improving visual quality and wavefront parameters in post-keratoplasty patients with pathologically irregular, mydriatic pupils.

Methods:
A total of 13 eyes of post-penetrating keratoplasty patients with pathologically irregular mydriatic pupil were included in this prospective interventional study. Preoperative wavefront analysis was done with the actual pupil size, and predicted wavefront values were analyzed by setting the postoperative pupil size to 2 mm. Patients showing significant improvement between preoperative and predicted postoperative wavefront values underwent single-pass four-throw pupilloplasty, and all wavefront parameters were again evaluated after 1 week. Preoperative and postoperative best corrected visual acuity (BCVA), pupil size, and wavefront parameters were analyzed.

Results:
Mean BCVA improved from a preoperative value of 1.03 ± 0.32 log of minimum angle of resolution (logMAR) units to 0.24 ± 0.09 logMAR units. Mean preoperative pupil size was 6.077 ± 0.787 mm, whereas the achieved postoperative pupil size after pupilloplasty was 2.538 ± 0.139 mm. Mean astigmatism root mean square (RMS) value improved from 4.169 ± 3.876 to 0.875 ± 0.926 µm (P < 0.05), and mean coma value changed from 1.525 ± 1.962 to 0.128 ± 0.152 µm (P < 0.05). Mean point spread function Stehl ratio value improved from 0.056 ± 0.032 to 0.223 ± 0.102. Mean RMS (optical path difference) value changed from 6.248 ± 4.721 to 0.943 ± 0.947 µm (P < 0.001), Mean RMS (high orders) value changed from 3.788 ± 3.537 to 0.328 ± 0.256 µm (P value 0.003), and the mean spherical aberration value changed from 0.646 ± 0.873 to 0.223 ± 0.102 µm (P value 0.024). All postoperative wavefront parameters showed statistically significant improvement from the preoperative parameters.

Conclusion:
Wavefront-guided pupilloplasty can predict and improve wavefront parameters and visual quality in post-keratoplasty patients with pathologically irregular mydriatic pupils.

Published: September 2024

Purpose:
To compare the visual outcomes of implantable Collamer lens (ICL) with small incision lenticule extraction (SMILE) in cases of moderate-high myopia.

Methods:
A prospective comparative study was conducted on 60 eyes of 30 patients with moderate-high myopia (−3D to −8D with astigmatism ≤1 D) at a tertiary eye care center. Patients underwent either SMILE or ICL in both eyes and had a postoperative follow-up of 1 year.

Results:
The manifest refractive spherical equivalent was −5.22 ± 1.05 D and −5.4 ± 1.17 D in the SMILE and ICL groups, respectively (P = 0.53). The mean sphere and cylinder were comparable between the groups. The mean uncorrected visual acuity improved from 1.18 ± 0.19 logMAR to 0.03 ± 0.07 logMAR in SMILE and 1.14 ± 0.25 logMAR to 0.011 ± 0.04 logMAR in the ICL group. The efficacy for SMILE was 83.3% and that for ICL was 93.3%. Safety and predictability (±0.5D) for both was 100%. A significant increase was observed in ocular aberration with a decrease in modular transfer function in the eyes that underwent SMILE, whereas no significant change in the eyes that underwent ICL. A significant difference was observed in all parameters of ocular aberration except corneal trefoil, corneal astigmatism, and PSF between the two groups at the final follow-up. The contrast sensitivity at final follow-up was higher in ICL cases when compared to SMILE. The quality of vision (QoV) score suggested a better QoV with ICL; however, the difference was not statistically significant.

Conclusion:
Both SMILE and ICL are safe in patients with moderate-high myopia. The efficacy, contrast sensitivity, and postoperative ocular aberration profile are better in cases undergoing ICL.
A new device, LMA Gastro™, on the horizon for endoscopy procedures: A narrative review
Authors: Gupta Anju , Saranlal A M , Gupta Nishkarsh 
Published: September 2024

Abstract
Interventional endoscopy procedures are challenging for anaesthesiologists due to the various patient, procedural, logistic, and position-related issues. Complex endoscopic procedures like biliary interventions and endoscopic myotomy necessitate longer procedural duration. The mode of anaesthesia is usually deep sedation without any definitive airway device and is frequently associated with hypoxemia events which can be catastrophic. An endotracheal tube, though the gold standard for securing the airway, would prolong the anaesthesia time and delay the recovery. The laryngeal mask airway Gastro™ is a novel supraglottic airway device specifically meant for these procedures as it provides access to the gastrointestinal tract simultaneously with a patent airway. Though its purported advantages are undoubted, its clinical usage has various pitfalls that can hinder its wider acceptance and practical utility, especially when newly introduced. The literature is limited on the feasibility of this device in both the ease of endoscopy and the prevention of hypoxemia. In this review, we have discussed the device’s properties, its varied use cases, the supporting evidence for the same, the caveats, and the future perspectives.
Towards a Historical and Philosophical Rethinking of Late Antique and Byzantine Thought. Book Review: Dugin A. G. Noomachy: Wars of the Mind. Byzantine Logos. Hellenism and Empire. M.: Academic Project, 2016. 519 p.
Authors: Медоваров М.В. 
Published: September 2024

Рассматривается книга А. Г. Дугина, входящая в цикл «Ноомахия» и посвященная философии эпохи эллинизма, поздней античности, Византии и современной Греции. В центре внимания находится методологическая и эвристическая ценность ноологической концепции «трех Логосов», через которую дается оценка различным историческим и культурным сдвигам в многотысячелетней истории греческой культуры. Особое внимание уделено оценкам языческих и христианских философов в свете неоплатонического понимания истории эллинистически-римской и византийской философии.
There is reviewed the book by Alexander Dugin being part of the “Noomachy” cycle and dedicated to the philosophy of the Hellenistic era, late Antiquity, Byzantium, Modern and contemporary Greece. The focus is made on the methodological and heuristic value of the noological concept of the “three Logoses”, through which various historical and cultural shifts in the millennia-long history of Greek culture are assessed. Particular attention is paid to the assessments of pagan and Christian philosophers in the light of the Neoplatonic understanding of the history of Hellenistic-Roman and Byzantine philosophy.
Averintsev and the Paschal Joy. On the Perception of Byzantine Christianity in Some Later Works of the Thinker
Authors: Макаров Д.И. 
Published: September 2024

В поздних статьях, выходивших на русском и английском языках, а также в монографии о Вяч. Иванове С. С. Аверинцев выделяет некоторые системообразующие черты византийского Православия — такие, как онтологизм, пасхальная радость, литургическое переживание радости и умиления, вызванное молитвенным переживанием Богородичного общения, центральное значение иконы, передающей человеческий Лик Господа Иисуса Христа. Также разбирается такой вводимый мыслителем в 90‑е гг. концепт, как «христианская геополитика»; подобные мысли восходят к традиции византийской и европейской консервативной философии (Томас Карлейль, отчасти Феодор Метохит). Концепция Аверинцева, феноменологически тончайшим образом описывающая византийское благочестие изнутри, противопоставляется внешне-барочному описанию византийской религиозности у Х.-Г. Бека, ставящего акцент на проблеме византийского воображаемого. Подчеркивается преемственность Аверинцева по отношению к мысли Вяч. Иванова и Н. С. Трубецкого.
In some later articles of his, published in English and Russian, as well as in the monograph on Vjacheslav Ivanov, Sergei S. Averintsev has singled out some basic features of the Byzantine Orthodoxy, such as its ontological character, the Paschal joy, liturgical experience of rejoicing and deep tenderness, which used to be caused by the communication with the Holy Virgin in prayer, and the central meaning of icon, which transmits to us the human Face of our Lord Jesus Christ. We also analyze such Averintsev’s concepts from the nineties of the 20th century, as “Christian geopolitics”; such-kind ruminations go back to the tradition of Byzantine and European conservative philosophy (Th. Carlyle, and — partially — Theodore Metochites). This Averintsev’s conception, which phenomenologically describes in the most subtle way the Byzantine piety from within, is juxtaposed to the outer, Barock-like description of the Byzantine religiosity produced by Hans-Georg Beck, the great German scholar putting his emphasis upon the problem of the Byzantine imaginary. We underscore Averintsev’s continuity in thought with Vjacheslav I. Ivanov and Nicholas S. Trubetzkoy.
Canonization of the Autobiographical Myth of Vyacheslav Ivanov in the Works of S. S. Averintsev
Authors: Кибальниченко С.А. 
Published: September 2024

Автобиографический миф, созданный поэтом и теоретиком символизма Вячеславом Ивановым, имеет сложную структуру. Его ядро сформировано целенаправленными усилиями самого писателя. Второй слой возник благодаря «семейному» биографу Ольге Шор (Дешарт). Осязаемым его воплощением стало четырехтомное собрание сочинений Иванова, изданное в Брюсселе. Третий слой создан знаменитым филологом С. С. Аверинцевым, который на протяжении трех десятилетий публиковал научные работы, посвященные поэту. Их отличает апологетический стиль и полное приятие образа Иванова, созданного им самим. Благодаря такому подходу в работах Аверинцева произошла канонизация автобиографического мифа поэта. Он лишился налета субъективности и во многом совпал с магистральной линией интерпретации творчества писателя в литературоведении. Недаром среди многочисленных научных публикаций об Иванове практически нет работ, посвященных автобиографическому мифу. В настоящей публикации делается первый шаг к осознанию этой проблемы и уточняется понятие «символистского канона».
The autobiographical myth created by the poet and symbolist theorist Vyacheslav Ivanov has a complex structure. Its core is formed by the purposeful efforts of the writer. The second layer arose thanks to the “family” biographer Olga Shor (Dechart). Its visible embodiment was the four-volume collected works of Ivanov, published in Bruxelles. The third layer was created by the famous philologist S. S. Averintsev, who for three decades published scientific works dedicated to the poet. They are distinguished by an apologetic style and complete acceptance of the image of Ivanov, created by himself. Thanks to this approach, Averintsev accomplished the canonization of the poet’s autobiographical myth. The autobiographical myth lost the touch of subjectivity and largely coincided with the main line of interpretation of the writer’s work in philological science. It is not surprising that among the numerous scientific publications about Ivanov, there are practically no works devoted to the autobiographical myth. This publication takes the first step towards understanding this problem and clarifies the concept of the “symbolist canon”.

The climate and vegetation of Europe, northern Africa, and the Middle East during the Last Glacial Maximum (21 000 yr BP) based on pollen data

Published: September 2024

Abstract. Pollen data represent one of the most widely available and spatially resolved sources of information about the past land cover and climate of the Last Glacial Maximum (LGM; 21 000 yr BP). Previous pollen data compilations for Europe, the Mediterranean, and the Middle East, however, have been limited by small numbers of sites and poor dating control. Here we present a new compilation of pollen data from the region that improves on both the number of sites (63) and the quality of the chronological control. Data were sourced from both public data archives and published (digitized) diagrams. The analysis is presented based on a standardized pollen taxonomy and sum, with maps shown for the major pollen taxa and biomes and the total arboreal pollen (AP), and on quantitative reconstructions of forest cover and of winter, summer, and annual temperatures and precipitation. The reconstructions are based on the modern analogue technique (MAT) adapted using plant functional type (PFT) scores and with a modern pollen dataset taken from the latest Eurasian Modern Pollen Database (EMPD) (∼8000 samples). A site-by-site comparison of the MAT and the inverse modelling method shows little or no significant difference between the methods for the LGM, indicating that the presence of low-CO2 conditions and no modern analogue during the LGM does not appear to have had a major effect on MAT transfer function performance. Previous pollen-based climate reconstructions using modern pollen datasets show a much colder and drier climate for the LGM than both inverse modelling and climate model simulations do, but our new results suggest much greater agreement. Differences between our latest MAT reconstruction and those in earlier studies can largely be attributed to bias in the small modern dataset previously used and to differences in the method itself (Brewer et al., 2008; Salonen et al., 2019). We also find that quantitative forest cover reconstructions show more forest than previously suggested by biome reconstructions but less forest than suggested by simply the percentage of arboreal pollen, although uncertainties remain large. Overall, we find that LGM climatic cooling and drying were significantly greater in winter than in summer but with large site-to-site variance that emphasizes the importance of topography and other local factors in controlling the climate and vegetation of the LGM.

Introduction. Stomach cancer continues to be one of the leading causes of mortality among malignant diseases. The study of various methods of surgical treatment is one of the directions of scientific search.The purpose of the study — comparison of the frequency of postoperative complications with laparoscopic and laparotomic access in patients who underwent radical treatment of gastric malignancies.Materials and methods. Retrospective evaluation of 189 patients diagnosed with malignant neoplasms of the stomach, operating under stationary conditions of the department of abdominal oncology of the Sverdlovsk Regional Oncology Center in 2023.Results and discussion. Length of hospitalization of patients operated by laparoscopic method, was reliably lower than the same number of patients, operated with laparotomy, which allows you to start adjuvant chemotherapy at an earlier date and thereby improve the distant results. In general, the traumatic indicators of surgery were less important in patients, operated laparoscopic method.Conclusion. Based on the data we’ve gathered, that although there is no statistically significant difference in the incidence of intraoperative and postoperative problems when performing laparoscopic and open radical operations in patients with malignant neoplasms of the stomach, the more benefits have laparoscopic access.
Stability Of Equilibrium States For A Stochastically Perturbed Pielou’s Equation [
Authors: A. Lallouche  
Published: September 2024

It is widely recognized that the theory of stochastic difference equations is a mathematical area of great interest. Concrete systems and processes is one of its subareas, which is of some interest nowadays. Specifically, in fields such as systems biology, ecology, biochemistry, genetics, and physiology dynamics, numerous population models are described by studying linear and nonlinear difference equations and systems. These studies have been very productive and helpful to develop the basic theory of the qualitative behaviour of nonlinear rational and exponential difference equations and systems. In this paper, we investigate a type of Pielou’s difference equation that is subject to additive stochastic perturbations modelled as a sequence of independent random variables (ξ_n ) with zero mean and unit variance. These perturbations are proportional to the deviation of the system state \(X_n \) from its equilibrium points, resulting in the following stochastic difference equation. X_(n+1)=(αX_n)/(1+X_(n-1) )+σ(X_n-X^* ) ξ_(n+1) where parameters a and σ have arbitrary values. Utilizing the general method of constructing Lyapunov functional for stochastic difference equations in discrete time, we establish necessary and sufficient conditions for the asymptotic mean square stability of the two equilibrium points (zero and positive). These conditions also serve as sufficient conditions for the stability in probability of the equilibrium points of the original nonlinear equation. To validate the derived results, numerical examples and simulations of equation solutions are presented, accompanied by numerous graphical illustrations of stability trajectories of solutions.
Handling Missing Data through Artificial Neural Network
Authors: Geeta Chhabra  
Published: September 2024

Missing data is a difficult problem to solve when working with real-world datasets. It is vital to improve data quality by imputing missing values in order to obtain effective data learning. Deep learning has recently risen to prominence as the most effective sort of machine learning technique for uncovering hidden knowledge in massive datasets and making accurate predictions. We have used “back-propagation artificial neural network” to impute categorical missing data. The main goal is to see how well “neural network” compares to statistics and machine learning for resolving categorical missing data. The results of “back-propagation” are compared with multiple imputation and random forest. It consistently outperforms alternative methods both in “training” and “test” data sets, showing that “neural network” is a suitable for reconstructing “missing values” in “multivariate analysis”.

Published: September 2024

The goal of this paper is to introduce fuzzy soft sequential topological spaces over the universal set via fuzzy soft sequential set by merging the concept of fuzzy soft set and sequential set. We provide a comprehensive study of their properties and explore a relationship between fuzzy soft topology and fuzzy soft sequential topology. We offers a new outlook on the theory of fuzzy soft sequential neighborhood of a fuzzy soft sequential set and we investigate the quasi-coincident relation.
PAÍSES EMERGENTES, CRISES E A DINÂMICA DOS FLUXOS DE CAPITAIS NO SISTEMA MONETÁRIO INTERNACIONAL
Authors: Weiss Mauricio Andrade , Sampaio Adriano Vilela 
Published: September 2024

Um dos aspectos fundamentais do sistema monetário e financeiro internacional (SMFI) contemporâneo é a alta volatilidade dos fluxos de capitais. Nesse cenário, os fluxos de capitais para os países emergentes são condicionados fundamentalmente pelos ciclos internacionais de liquidez e pelo caráter hierárquico do sistema monetário internacional (SMI). Como consequência, a experiência dos países emergentes que optaram pela estratégia de ampla abertura financeira tem se mostrado insatisfatória frente ao caráter instável dos fluxos. Três fases distintas foram observadas desde a eclosão da crise financeira global de 2008 (CFG): i) a CFG e suas respectivas fases; ii) a política monetária não convencional (PMNC) adotada pelas economias avançadas e a decorrente abundância de liquidez internacional; e iii) as taper talks e o posterior fim das PMNC nos EUA. Constatou-se também que os países emergentes que mantiveram ou acentuaram a opção pela abertura financeira não foram capazes de se proteger adequadamente das oscilações dos fluxos, mesmo aqueles cujos indicadores sugeriam uma baixa vulnerabilidade externa. Em contraste, o emprego de técnicas de gestão de capitais mostrou-se efetivo para atenuar os impactos dos ciclos de liquidez internacional nessas economias.
