Published: August 2023

Exclusive breasfeeding is one of the Sustainable Development Goals programs that aim to provide good nutrition for babies naturally. Given the far-reaching benefits of exclusive breastfeeding for babies, mothers and the economy, concerted efforts are needed to meet the World Health Assembly (WHA) target of at least 50% exclusive breastfeeding for 6 months by 2025. The exclusive breastfeeding coverage rate is still far from the expectations removed. This is to be expected as only 1 in 2 babies under 6 months are exclusively breastfed. This shows that almost 50% of Indonesia's child population does not receive the nutrition they need in the first two years of life. The WHO reports that more than 40% of infants were introduced to complementary foods before the age of 6 months and were given food that did not meet their nutritional needs. The aim of this study is to analyze factors related with successful in exclusive breastfeeding during a pandemic. This research is an observational, analytic, cross-sectional study. The sample in this study were mothers whom have toddlers aged 6-18 months from January 2020 to July 2021. The number of samples is 138 people. Data analysis will use the Chi Square test, fisher, and logistic regression. The results showed that the spacing pregnancy (p value = 0.010), Covid-19 infection during delivery or breastfeeding (p value = 0.017), and knowledge (p value = 0.013) had a significant relationship with exclusive breastfeeding. The dominant factor influencing exclusive breastfeeding is knowledge. The probability of logistic regression is seen with a value of 0.99

Published: August 2023

The subject of the study is the specifics of the coverage of the topic of creative industries in federal and district media. The object of the research is creative industries as a subject of journalistic creativity. In our country, there is an increasing interest in the field of creative industries, as a sector of the economy that has high development opportunities. In this regard, the role of journalism is also increasing, which not only informs readers about this area, but also attracts the attention of investors, the state, and business to it. Therefore, an effective presentation of the topic of creative industries on the pages of the media is a fairly new and urgent task for both federal and regional communities. Moscow and the Khanty-Mansi Autonomous Okrug – Yugra are currently examples of successful development of the creative industries in the country. The article analyzes the materials published in the newspapers "Evening Moscow", "Arguments and Facts", "News of Ugra" and "Arguments and Facts – Ugra" from October 2022 to May 2023. The authors come to the conclusion that 1) in the federal media, when choosing a genre, preference is given to such a genre as news, the main goal is to entertain the reader, to demonstrate the level of support for local initiatives by the authorities. 2). In the district media, on the contrary, creative industries are often covered in the genre of reportage, immersing the reader in a creative atmosphere, familiarity occurs not only with the product, but also with the process of its creation, with the emotions that interaction with the product gives. 3). In the federal media, there is a tendency to focus on the consumer properties of the creative product, the profitability indicators of the project, the possibilities of using the product in a new area, compliance with trends. 4). There is a tendency in the district media to increase interest in local projects that are based on historical and cultural heritage and art.
Towards the Communicative Strategies of Russian Modernism: the Poetic Correspondence of V. Bryusov and A. Bely
Authors: Kartasheva Anna Olegovna , Kikhnei Lyubov' Gennad'evna , Osipova Olga Ivanovna
Published: August 2023

The object of this article is the poetic correspondence of Valery Bryusov and Andrei Bely in the 1900s. The analysis allowed us to draw a number of conclusions about the communicative strategies of Russian modernism. Firstly, in the structure of the correspondence, the dominant genre setting for dialogue with the addressee is identified, which allows identifying these poems as messages. This, on the one hand, makes it possible to fit the messages of Bryusov and Bely into the all-symbolist poetological and communicative context of the early twentieth century, when this genre was a kind of mainstream. On the other hand, the analysis of genre dominants allows us to identify their genre renewal associated with the formation of an original metastructural cycle resembling a "novel in letters", the heroes of which are Bryusov and Bely, simultaneously combining the roles of author and addressee. Secondly, in the titles of the poems under consideration ("Balder Loki", "Balder II", "Ancient Enemy", "Magician"), mythological codes are revealed, genetic links are established with Christian apocrypha and Scandinavian legends, in which the author's "I" and "you" of the addressee are associated with images of light and dark forces rooted in religious and pagan traditions. Thirdly, with the help of the biographical method, the parallels of the lyrical plots of the poems with the life and creative relationships of the poets are established. As a result, the poetic correspondence of the masters of symbolism is interpreted as a philosophical duel implicitly realizing dramatic situations of personal and "workshop" relationships, with a clear separation of aesthetic and ethical roles, these roles structure the plot of an epistolary "novel", the vicissitudes of which are reduced to binary oppositions of "light" and "darkness", heavenly and earthly, divine and demonic principles. However, at the same time, this exchange of messages appears as a dialogue about the poet's role in symbolist discourse, a dialogue reflecting different vectors of creative aspirations of symbolists and, consequently, the ambivalent tendencies of the current towards both consolidation and separation.
Determining the Effective Space Debris Attitude Motion Modes for Ion-Beam-Assisted Transportation
Authors: Ledkov Alexander S.
Published: August 2023

Contactless space debris transportation systems based on the use of an ion beam are a promising direction among active space debris removal systems. The magnitude of the force generated by the ion beam depends on the orientation of the space debris object in the ion beam created by an active spacecraft. During the ion transport process, the space debris object can oscillate or rotate, which leads to a change in the generated force. The aim of this study is to develop an algorithm for determining the attitude motion mode of space debris, which is most favorable for its contactless transportation. The time-averaged generated ion force is used as the performance index. A simplified system of equations describing the spatial motion of a cylindrical axisymmetric object in a circular orbit is obtained. A generalized energy integral is found. An algorithm for determining the most favorable angular motion mode of a space debris object is developed. A numerical study of a cylindrical space debris object attitude motion under the action of an ion torque is carried out. The favorable attitude motion mode is determined, and the average forces in the most favorable and unfavorable modes are compared.

BALLET DANCERS OF THE TURN OF THE 20TH CENTURY IN THE PLASTIC INTERPRETATION OF B. FREDMAN-KLUZEL
Authors: PORTNOVA TATIANA
Published: August 2023

The article is devoted to notable events in the theatrical life of the turn of the 20th century, when ballet dancers often became models for artistic works. The author refers only to one sculptor B. O. Fredman-Kluzel (1878-1959), whose name is little known in art history, despite the fact that some of his works are in large museum collections. They partly served as a source for the research, as well as old printed publications in which reproductions of the sculptor’s works are found and Sotheby’s catalogues, because his works were auctioned during S. Diaghilev’s “Russian Ballet Seasons” and most of them are abroad. The methodology of this study is based on a systematic, interdisciplinary and stylistic approach. The author comes to the conclusion that the signifi cance of the artistic heritage of B. O. Fredman-Kluzel is determined by the achievements of the ballet theatre itself, the staging principles of M. Fokin, outstanding personalities, as well as the genre, content and aesthetic side of choreographic works created at the turn of the 20th century.

Published: August 2023

Deep learning has become a powerful and frequently employed tool for the prediction of molecular properties, thus creating a need for open-source and versatile software solutions that can be operated by non-experts. Among current approaches, directed message-passing neural networks (D-MPNNs) have proven to perform well on a variety of property prediction tasks. The software package Chemprop implements the D-MPNN architecture, and offers simple, easy, and fast access to machine-learned molecular properties. Compared to its initial version, we present a multitude of new Chemprop functionalities such as the support of multi-molecule properties, reactions, atom/bond-level properties, and spectra. Further, we incorporate various uncertainty quantification and calibration methods along with related metrics, as well as pretraining and transfer learning workflows, improved hyperparameter optimization, and other customization options concerning loss functions or atom/bond features. We benchmark D-MPNN models trained using Chemprop with the new reaction, atom-level and spectra functionality on a variety of property prediction datasets, including MoleculeNet and SAMPL, and observe state-of-the-art performance on the prediction of water-octanol partition coefficients, reaction barrier heights, atomic partial charges, and absorption spectra. Chemprop enables out-of-the-box training of D-MPNN models for a variety of problem settings in a fast, user-friendly, and open-source software.

Central roles of Mn2+ ions in immunity, brain function, and photosynthesis, necessitate probes for tracking this essential metal in living systems. However, developing a cell-permeable, fluorescent sensor for selective imaging of Mn2+ ions in the aqueous cellular milieu has remained a challenge. This is because Mn2+ is a weak binder to ligand scaffolds when compared to other physiological metal ions, in water. Here we report a water-soluble, fluorescent turn-on, Mn2+ selective sensor that enters living cells within 15 min of direct incubation and enables imaging of Mn2+ dynamics in live mammalian cells. We reveal differential Mn2+ localization and dynamics in disease model cells replicating conditions of Mn-induced Parkinsonism compared to normal cells. The computationally-designed sensor with a 620 nM limit-of-detection for Mn2+ in water, distinctly overcomes selectivity, sensitivity, and cell-impermeability issues associated with the few reported Mn2+ probes, thus opening floodgates to elucidate the hitherto intractable mammalian Mn2+ homeostasis.
Sample Efficient Reinforcement Learning with Active Learning for Molecular Design
Authors: Dodds Michael , Guo Jeff , Löhr Thomas , Tibo Alessandro , Engkvist Ola , Janet Jon Paul
Published: August 2023

Reinforcement learning (RL) is a powerful and flexible paradigm for searching for solutions in high-dimensional action spaces. However, bridging the gap between playing computer games with thousands of simulated episodes and solving real scientific problems with complex and involved environments (up to actual laboratory experiments) requires improvements in terms of sample efficiency to make the most of expensive information. The discovery of new drugs is a major commercial application of RL, motivated by the very large nature of the chemical space and the need to perform multiparameter optimization (MPO) across different properties. In silico methods, such as virtual library screening (VS) and de-novo molecular generation with RL, show great promise in accelerating this search. However, incorporation of increasingly complex computational models in these workflows requires increasing sample efficiency. Here, we introduce an active learning system linked with an RL model (RL-AL) for molecular design, which aims to improve the sample-efficiency of the optimization process. We identity and characterize unique challenges combining RL and AL, investigate the interplay between the systems, and develop a novel AL approach to solve the MPO problem. Our approach greatly expedites the search for novel solutions relative to baseline-RL for simple ligand- and structure-based oracle functions, with a 1000-75 000%-increase in hits generated for a fixed oracle budget and a 14-65-fold reduction in computational time to find a specific number of hits. Furthermore, compounds discovered through RL-AL display substantial enrichment of a multi-parameter scoring objective, indicating superior efficacy in curating high-scoring compounds, without a reduction in output diversity. This significant acceleration improves the feasibility of oracle functions that have largely been overlooked in RL due to high computational costs, for example free energy perturbation methods, and in principle is applicable to any RL domain.
Improved Quantification of Carbonyl Sub-metabolome by Liquid Chromatography Mass Spectrometry using a Fragment Controlled Multiplexed Isotopic Tag
Authors: Tian Xiaobo , Hopfgartner Gérard
Published: August 2023

Background: Carbonyl-containing metabolites are a class of key intermediate in metabolism, which has potentials to be biomarkers. Since their poor ionization, derivatization reagents, such as dansylhydrazine, are usually used to improve the sensitivity and/or to facilitate quantification. However, most current carbonyl derivatization reagents only have two channels, one is isotopically labeled and the other one is non-labeled. To quantify more samples in a run and using data-independent acquisition (DIA) mode to get comprehensive and unbiased mass fragmentation, we proposed a fragment-controlled isotopic tag, called DiMe-FP-NHNH2 (FP) which has five channels: Δ0, Δ3, Δ6, Δ9, and Δ12, thus up to 5 samples can be analyzed in a run. Results:. The most important improvement is that the FP tag can produce multiple characteristic signals in tandem mass, diagnostic ions and neutral losses, which helps to selectively detect aldehydes/ketones for targeted and untargeted analysis. To exhibit all capabilities of the FP tag, we mimicked an untargeted metabolomics experiment, which comprises two steps. First, discovery step, using Data-Independent Analysis (SWATH-MS) and the labeling of two channels (Δ0 and Δ3), we picked out aldehyde/ketone from the pooled urine samples based on three characteristic signals, including isotope patterns, diagnostic ions, and neutral losses. Second, five-plex quantification, relative and absolute quantification were achieved in a single LC-MS analysis. Notably, because of different nominal masses, the FP tag can be used on any low or high resolution mass spectrometers Significance: The benefits and performance of the FP tag are demonstrated by the analysis of urine samples collected from patients from a prostate cancer study, in which more than a thousand features were found based on MS1 fingerprint, but only around 120 aldehyde/ketone candidates were confirmed with characteristic signals and nine of which were quantified showing significant differences from healthy and reference urine samples.

Syzgium aromaticum is an evergreen spice plant with biocidal and insecticidal activities. The study was conducted to evaluate the potential of Syzgium aromaticum oil as a safe alternative to synthetic agrochemicals currently used for the control of Callosobruchus maculatus, the principal post-harvest pest of cowpea (Vigna unguiculata)- a major plant protein source in Africa. Pulverised dried flower buds of Syzgium aromaticum were extracted by hydrodistillation using Clevenger apparatus to obtain clove oil. The oil was characterized using gas chromatography-mass spectrometry (GC-MS) technique and the major components of the oil were eugenol (72.8%) and β-caryophyllene (19.5%). Two experiments were conducted to evaluate the potency of the clove oil in the control of Callosobruchus maculatus. The repellency of the oil was evaluated using the area of preference method. Adults Callosobruchus maculatus were released separately at the center of the Whatman No.1 filter infused with 1mL of 100 ppm- 400 ppm clove oil in covered petri dishes. Ethanol was used as control. The treatments were assigned in a completely randomized design. The number of insects present on the control and treated papers were recorded 1 hr and 2 hr after exposure and percent repellency was calculated. In the second experiment, 20 g of the cowpea seeds were treated with 100-400 ppm clove oil, with ethanol as a negative control and pirimiphos-methyl as positive control. They were exposed to C. maculatus in a jar covered with mesh. Mortality was recorded 24, 48, 72 hr after infestation. The highest repellency of 35% occurred after 2 hrs of exposure to 200 ppm clove oil. Thus, clove oil did not significantly repel C. maculatus. Nonetheless, exposure of C. maculatus to 300 ppm clove oil for 72 hours after infestation inflicted high mortality of 64.6% comparable to that of the synthetic insecticide pirimiphos-methyl (75%). Thus, clove oil is a safe alternative for the control of C. maculatus. Keywords: Food Safety, Syzgium aromaticum, biocides, Callosobruchus maculatus

Sulfoquinovose (SQ or 6-deoxy-6-sulfoglucose) is a sulfosugar that is the anionic head group of plant and cyanobacterial sulfolipids: sulfoquinovosyl diacylglycerols. SQ is produced within photosynthetic tissues, forms a major terrestrial reservoir of biosulfur, and is an important species within the biogeochemical sulfur cycle. A major pathway for the breakdown of SQ is the sulfoglycolytic Embden-Meyerhof-Parnas (sulfo-EMP) pathway, which involves cleavage of the 6-carbon chain of the intermediate sulfofructose-1-phosphate (SFP) into dihydroxyacetone and sulfolactaldehyde, catalyzed by class I or II SFP aldolases. While the molecular basis of catalysis is well studied for class I SFP aldolases, comparatively little is known about class II SFP aldolases. Here, we report the molecular architecture and biochemical basis of catalysis of two metal-dependent class II SFP aldolases from Hafnia paralvei and Yersinia aldovae. 3D X-ray structures in complex with the substrate SFP and product DHAP reveal a dimer-of-dimers (tetrameric) assembly, and identify the sulfonate binding pocket that defines the substrate specificity of these enzymes, two metal binding sites, and flexible loops that are implicated in catalysis. Both enzymes were metal dependent and exhibited high KM values for SFP, consistent with their role in a unidirectional nutrient acquisition pathway. Bioinformatic analysis identified a range of sulfo-EMP gene clusters containing class I/II SFP aldolases. The class I and II SFP aldolases occur exclusively within Actinobacteria and Firmicutes phyla, respectively, while both classes of enzyme occur within Proteobacteria. This work emphasizes the importance of SQ as a nutrient for diverse bacterial phyla and the different chemical strategies they use to harvest carbon from this sulfosugar.
Multimodality and cross-modal cohesion in manga
Authors: Yefymenko Victoria
Published: August 2023

Manga with their distinct style and symbolism represent a growing reading trend in the world. Manga use an established set of symbols to convey various emotions. Manga have generally been more experimental in layout than Western comics. They are more fragmentary and contain more panels that enhance the dynamism of the story. We aimed to outline methodological approaches to the analysis of manga; to summarize specific features of manga as a separate medium; to analyse how multimodal cohesion is created in manga; to reveal various types of relations between visual and verbal modes. Manga is a multimodal discourse, combining several modes, mainly visual and verbal. The aural mode is represented by linguistic and visual signs, e.g. jagged borders of a speech bubble or the size and boldness of letters. We applied methods originally designed for the film analysis to the analysis of manga, in particular, Tseng’s (2013) theory of cross-modal cohesion, based on tracking cross-modally realized characters, objects, actions, and settings. This analysis included building cross-modal cohesive chains. We argue that it is possible to track cross-modal cohesion in manga, based on the interaction of visual, verbal, and aural components of identity chains. Besides, the interaction between visual and verbal modes was revealed by analysing text-image relations. In this paper we have outlined manga-specific features, distinctive features of manga’s page layout, cinematic devices, which manga borrowed from films, some of which may be used as focalisation-marking devices.

The presence of microplastics (MPs) and nanoplastics (NPs) in the environment is ubiquitous, and as such, the toxicity of these plastics, exposure scenarios, and mechanisms of plant response is to be determined. Hereby, a meta-analysis is performed to investigate the effects of MPs and/or NPs on different plant species under hydroponics and soil conditions to assess the current scenario. We examined the response level of root system, photosynthetic parameters, and antioxidant system of plants against MPs/NPs. Root response level in soil condition against various concentrations and types of MPs was higher than in hydroponics however, this response was opposite for the types of MPs. Photosynthetic parameters, including chlorophyll a and b, carotenoids, total chlorophyll, and maximum quantum efficiency of PSII were higher in soil conditions than in hydroponics. Antioxidant parameters, such as malondialdehyde (MDA) and H2O2 contents were higher in hydroponics plants, while, superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) showed a mix trend of response level. In addition, proline content was significantly higher in soil and ascorbic acid (ASA) in hydroponic cultured plants under different types, sizes, and concentrations of MPs. These three systems i.e., root, photosynthesis, and antioxidant parameters were also compared between different species, however, the results are generally consistent with the above mentions one. Overall, these analyses suggest that plants grown in hydroponics are more sensitive to the plastic pollution than in the soil environment.

Authors: Iksan Muhamad , Soong Jenn-Jaw , Anandi Muhammad Fajar
Published: August 2023

This paper explores three main topics pertinent to a better description of Jakarta in the time of economic and political changes. The first topic illustrates how the Indonesian central government gradually conducts the capital transformation to Nusantara. The second depicts challenges for the city of Jakarta involving acute environmental and human-made problems: floods, sea level rise with severe land subsidence and traffic congestions. The third topic suggests a collaboration among key stakeholders. The central government emphasizes main resources to foster a joint action among ministries and agencies in the newly established city authority agency and coordination with international communities, donors, and investors, for successful capital development. The Jakarta local government coordinates the public and private sources to revitalize the city under the urban regeneration vision of 2030. The orchestrated efforts for constructive cooperation between central and local government culminates in the main argument of this paper which discusses collaborative governance with starting conditions as an important factor.
City Networks as Tools of City Diplomacy – the Case of Seoul
Authors: Kamiński Tomasz , Matiaszczyk Natalia
Published: August 2023

Confronting global challenges and wanting to make profits out of globalization, cities are becoming more active in global politics. They conduct city diplomacy, establishing bilateral connections with “sister cities” or through transnational city networks. In this context, the behavior of so-called global cities is fascinating because they have enough resources to be very influential on the world stage. The capital city of South Korea is one of these global cities. Seoul positions itself as a global player that is actively involved in many regions around the world. The Seoul Metropolitan Government aims to enhance its status in the international community as a global city by engaging in city networks, hosting its headquarters, and trying to influence other members of organizations. The phenomenon of using a city network as an instrument in the city public diplomacy toolbox has never been described within literature. This paper’s main aim is to conceptualize the instrumental use of a city network by a global city to promote its interests. We will analyze the case of Seoul, a member of 25 different city networks. Two of them, CityNet and World Smart Sustainable Cities Organization (WeGO), have headquarters in the South Korean capital city and are used as tools in Seoul’s public diplomacy. Based on interviews with city officials and networks officers, we will try to reconstruct the model of dependencies between the city and the networks it hosts. It will lead to answering the question of how the global city can use the network as a tool of its diplomacy. This paper will contribute to the academic discussion on city diplomacy instruments and help understand the internal policy-making process inside city networks that determine their actions in international relations.
Issues and Perspectives on the Water Crisis of Metro Manila Cities, Philippines
Authors: Rocina Jose Aims R.
Published: August 2023

This study delves into one of the most prevalent problems of Metro Manila: Sufficient Water Supply. With its burgeoning population, the Metropolis is an amalgamation of common problems of Asian cities: pollution, traffic jams and the lack of basic necessities such as water. The lack of recycling facilities, reliable water supply, and an uncontrollable wastage of commodities by the populace are just some of the causes of this social malady and economic malaise. If these problems are not addressed properly, these cities will soon experience not only a substantial loss of income but also a loss of lives. This paper will provide a deep perspective on the different issues involved: the history of the problem, the underlying issues, the root causes, the proposal of economic and political gurus and the most plausible alternative to solve it. With potable water always at a critical level, with Angat Dam as its primary source of water, the Metropolis is at the mercy of natural elements such as rain and the summer heat. Its main proposal to tap the Kaliwa River into a dam has met stiff opposition from the local natives in the area and from environmental groups. Unfortunately, time is running out and soon, the supply of water will soon run out too.

Published: August 2023

In the last 20 years, the world economy has shown fast progress towards globalization and urbanization around the world. Urbanization reflects the shift in employment from the agricultural to the industrial and service sectors which is a prerequisite for economic growth. The growth rate of the urban population is increasing very fast due to better living standards and higher employment opportunities in urban areas. Smart cities have been determined as a solution to cater for these problems where the technology will integrate with all city components to provide a good quality of life. As a result, India must properly plan for rethinking and restructuring its existing cities, and the construction of new cities using cutting-edge technology over the decade. This chapter tries to evaluate the essence of smart cities from the Indian context. It describes how urbanization in the world has forced India to think of smart cities. It also describes what was the need for smart cities and how the 100 smart cities were selected in India. This paper then evaluates the Indian smart cities mission based on six parameters, i.e., financing, coordination between the center and the states, master plan, time frame, facilities, and corruption. In the end, certain recommendations are being made to make the Indian Smart Cities Mission successful soon.
