Multi-region phase response calibration of SLM based on a Shack–Hartmann wavefront sensor
Authors: Zhai Zhongsheng , Jia Yuxuan , Zeng Zhen , Feng Wei , Liu Da
Published: November 2024

In order to accurately measure the phase modulation capability of the spatial light modulator (SLM) and improve its performance in optical applications, a multi-region phase response calibration scheme of SLM based on the Shack–Hartmann wavefront sensor (SHWS) is proposed. This scheme addresses the nonlinear sampling issue of the liquid crystals in different sampling areas on the SLM. By loading and shifting dual sine phase patterns, continuous variations of grayscale values in the same region on the SLM screen were achieved, with the corresponding wavefront data recorded by the SHWS after each grayscale change. Matrix calculations were performed in MATLAB to obtain the corresponding phase modulation curve. Subsequently, the multi-zone phase modulation characteristics of the SLM were measured. Following the nonlinear calibration of phase modulation in each zone of the SLM, the intrinsic wavefront distortion (WFD) of the SLM was measured using the SHWS in conjunction with the calibration results and compensated for. The compensated WFD of the SLM is reduced from 0.7976λ to 0.3415λ (λ=632.8nm), and in the verification experiment, the focused spots’ quality was greatly improved with the calibrated SLM. The experimental results proved the availability of the multi-region phase response calibration scheme. Compared to conventional methods, this approach demonstrates simplicity, real-time performance, and robustness.
Application of the Hilbert-Huang transform to evaluate signals in chromatic confocal spectral interferometry
Authors: Zhao Yulu , Chang Songtao , Zhang Yi , Xia Haojie
Published: November 2024

Chromatic confocal spectral interferometry (CCSI) is a hybrid measurement technique that integrates the principles of spectral interferometry and chromatic confocal microscopy. This innovative approach enables scanning-free acquisition of axial dimensions while leveraging interferometric methods to enhance depth accuracy. This feature allows the CCSI signal to be processed using both peak extraction and evaluation of the interferometric optical path length difference. The phase information offers a decreased measurement uncertainty, making it a commonly used approach in existing studies. Methods such as Fourier transform (FT) and wavelet transform (WT) are frequently employed for this purpose. In this paper, we present a signal processing approach based on the Hilbert-Huang transform (HHT). Through simulations and experiments, we compare HHT with Fourier transform (FT) and wavelet transform (WT), demonstrating its stability, noise resistance, and effectiveness in phase extraction for CCSI measurement signals. Additionally, we leverage the characteristics of CCSI signals and the time-frequency analysis capabilities of HHT to address the direction ambiguity problem in white light interferometry.

Far ultraviolet-C irradiation at 222 nm has potent bactericidal effects against severe infections such as peritonitis, with minimal cytotoxicity. Bacterial peritonitis due to bowel perforation is a serious condition with high mortality despite current treatments. This study investigated the safety and efficacy of intraperitoneal far ultraviolet-C irradiation at 222 nm. In vitro experiments optimized the fluid conditions for bacterial or protein concentrations prior to in vivo evaluation. In vivo efficacy was assessed in a rat peritonitis model induced by Escherichia coli, measuring intra-abdominal bacterial concentration, blood cytokine levels, and mortality rates. Safety was evaluated by analyzing cyclobutane pyrimidine dimers as markers of DNA damage in five abdominal organs: stomach, small intestine, colon, liver, and spleen. Statistical analyses employed parametric methods for normally distributed data and non-parametric methods for data without normality. Optimal in vitro conditions included 106 CFU/mL bacteria, 0.5 mW/cm2 irradiation, and 10−3 mg/mL protein. In the rat model, far ultraviolet-C irradiation at 222 nm significantly decreased intra-abdominal bacteria, reduced blood cytokines (interleukin-1β and interleukin-6), and elevated survival rates from 20% to 60%, compared to lavage alone. The formation of cyclobutane pyrimidine dimers was significantly lower with 222 nm irradiation than with 254 nm, suggesting reduced DNA damage. These findings indicate that far ultraviolet-C irradiation at 222 nm, when combined with lavage, represents a promising therapeutic strategy for bacterial peritonitis, providing effective bacterial reduction and a favorable safety profile. Further research is needed to verify these findings and investigate long-term safety and potential clinical applications.

Published: November 2024

Inter-Satellite Optical Wireless Communication (Is-OWC) is a pivotal technology for advancing global connectivity and the effectiveness of space-based operations. It serves as the linchpin for various applications such as global internet coverage, Earth observation, and remote sensing, bolstering our capacity to monitor the planet and deliver essential services. This paper presents the design and performance evaluation of a Polarization Division Multiplexing (PDM) and Multiple Input Multiple Output (MIMO)-based Is-OWC system operating at a data rate of 60 Gbps. The system was tested under varying transmission distances, atmospheric turbulence, and pointing error conditions. At a transmission distance of 10,000 km, the system achieved a Bit Error Rate (BER) of 6.76 × 10⁻3 for Channel 1 (X polarization) and 7.1 × 10⁻3 for Channel 4 (Y polarization), both within Forward Error Correction (FEC) limits. The introduction of a 4 × 4 MIMO configuration extended the transmission range to 14,000 km, with a corresponding BER of 9.1 × 10⁻3 for Channel 1 and 8.7 × 10⁻⁵ for Channel 4. Eye diagrams confirm successful signal reception, demonstrating that the system can maintain high data rates and low error rates over long distances. The proposed PDM-MIMO system showcases high-capacity, robust performance under challenging conditions, such as turbulence and pointing errors, validating its suitability for space-based communication applications. These findings highlight the potential of the system for future deployments in satellite networks, offering reliable, high-throughput, and low-latency data transmission over extended distances.
Food security and nutritional vulnerability in Comoros: The impact of Russia-Ukraine conflict
Authors: Custodio Estefanía , Ramos Maria Priscila , Jimenez Sofía , Mulangu Francis , Depetris-Chauvin Nicolas
Published: November 2024

The Sustainable Development Goal 2 aims to eradicate hunger. However, many small island developing states (SIDS) face challenges in achieving this goal due to their reliance on the global market and susceptibility to crises. This paper focuses on Comoros, one of the least studied SIDS located in the Indian Ocean, to examine its food security and nutritional vulnerability. The findings reveal that Comoros experiences limited access to sufficient and nutritious diets, which are excessive in fat and deficient in key micronutrients. This situation is similar to other SIDS in the Pacific and the Caribbean, which also exhibit the convergence of the malnutrition triple burden. This paper further assesses the impact of changing food prices during the initial year of the Russia-Ukraine conflict on food security and nutrition in Comoros, serving as a case study for SIDS. Using microsimulations, we estimate the effects on food access, sufficiency, and adequacy at the household level. The results indicate a decline in food access and purchasing power for all households, particularly the poorer and rural. Additionally, food sufficiency has markedly decreased, leading to an additional 5,000 households (3.3% of all households) experiencing inadequate daily calorie intake. The study also highlights a reduction in the consumption of organ meats, fruits, and vegetables, resulting in decreased daily iron and folate intakes. This is particularly concerning given the high prevalence of anemia among women in Comoros and other SIDS. To address these challenges, policies promoting the consumption of fresh, nutrient-rich foods with low fat content are crucial to mitigate the malnutrition triple burden and curb the increasing trend of non-communicable diseases in these countries.

Para além da noção de bens ambientais:
Authors: Wienke Felipe Franz , Altmann Alexandre
Published: November 2024

Os serviços ecossistêmicos são, por definição legal e científica, os benefícios relevantes para a sociedade gerados pelos ecossistemas. A ciência ambiental evidenciou, nas últimas duas décadas, a essencialidade desses serviços para o bem-estar humano, bem como os riscos advindos de seu colapso. Por esses motivos, o conceito de serviços ecossistêmicos tem sido internalizado em diversos ordenamentos jurídicos, passando a fundamentar novas políticas públicas – a exemplo da nova Política Nacional de Pagamento por Serviços Ambientais brasileira (Lei 14.119/2021). A noção de serviços ecossistêmicos, portanto, faz avançar o Direito ao traduzir em linguagem jurídica a complexidade da dependência do ser humano em relação aos ecossistemas e à biodiversidade. O presente artigo visa investigar os impactos que este conceito pode abarcar para alguns institutos do direito e da política ambiental relacionados à compensação ambiental. Como hipótese, sugere-se que a noção de serviços pode complementar o conceito de bens ambientais, evitando que os instrumentos de compensação autorizem uma substitutibilidade automática e pouco criteriosa entre elementos naturais. A pesquisa é proposta a partir do método indutivo, utilizando-se técnicas bibliográficas e documentais.

Attention to Oneself in an Apologetic Perspective: The Reception of Ancient Philosophical Practices in St. Basil the Great
Authors: Kaminis Ioannis
Published: November 2024

The purpose of this article is to present Saint Basil’s utilization of the philosophical heritage along with the ancient Greek literature for the benefit of Christianity. Saint Basil’s approach was influenced by a lineage of Christian philosophers, including the St. Justin the Philosopher, Origen, St. Gregory Thaumaturgus and his grandmother St. Macrina the Elder. Initially, early Christians like St. Justin the Philosopher and Clement of Alexandria portrayed Christianity as the true philosophy and the culmination of knowledge in antiquity. Then Origen employed more philosophical methods and practices in his Christian educational program. St. Basil followed this tradition, but infused his teaching with a holistic Christian interpretation. For instance, he emphasized attention to oneself in a Christian perspective. Additionally, his Address to the Young: On how they might derive benefit from Greek literature demonstrates Christianity’s capacity to assimilate and embrace other traditions while interpreting them in a manner that promotes virtue, the moral development of human being and devotion to Christ.
Odinala Traditional Religion as Part of Igbo Catholic Christian Identity
Authors: Havelka Ondřej
Published: November 2024

Although recent statistics indicate that the majority of the Igbo – an ethnic group living mainly in West African Nigeria – claim to be Christian (of various denominations), their religious identity is in fact more complex: the Igbo do not forget their traditional Odinala religion and practice it together with Christianity without intermingling (multiple religious identity) or in syncretism with Christianity. Odinala is, in short, a polytheistic religious system where the highest reverence belongs to the god Chukwu. The aim of this article is firstly to give an introduction to the traditional Igbo religion of Odinala and secondly its influence on the co-formation of the identity of the Igbo – we choose for the purpose of this article – Catholic Christian. Through the ontological categories of Odinala religion, the paper examines how Odinala shapes the Igbo worldview, how it co-constitutes Igbo identity and helps to establish the ontological category of the human person. The topic is developed through a field research method, reinforced by a comparison of relevant literature.
Misje i cele instytucji kultury
Authors: Ablewicz Joanna
Published: November 2024

This article uses various examples to show how the different goals of cultural institutions are being realised in practice. The mission of each cultural institution is the starting point for many plethora of tasks carried out by the in- stitution. It is clearly intended to exhibit why and for whom the institution exists, what it does, what its values are and what it aims to become. This mission should be unique for each cultural institution and permanent. Selected mission state- ments are discussed with examples to demonstrate whether cultural institutions articulate it correctly and understand their importance. An objective, on the other hand, is one of the elements of a cultural institution’s mission; it is something that the cultural institution wants to achieve through the actions it undertakes and, as indicated, follows from the mission. Objectives are a detailed refinement of the mission and may change in response to the changing environment in which the cultural institution operates. The article discusses the objectives of cultural institutions deriving from specific legal acts, and the way in which they are formulated by individual entities, and also analyses  statutes, regulations and other acts concerning how specific cultural institutions function. Particular attention is paid to the objectives of cultural institutions from the perspective    of the recipient, as it is the recipient who really decides (through participation  in the cultural activities of the institution) whether the institution properly ful- fils its objectives. An analysis of selected goals of cultural institutions shows that, as a rule, these institutions define their objectives in a very general way, merely repeating the wording indicated, for example, in the Cultural Activities Act. Objectives formulated in this way do not correctly reflect the scope of the cultural institution’s activities.
Unorthodox – Dantes Selbstautorisierung im poema sacro
Authors: Scherer Ludger
Published: November 2024

Riassunto

In questo articolo, la ›Commedia‹ di Dante non viene letta come ›Divina‹, ma come un testo di finzione il cui autore immunizza strategicamente l’opera dai possibili attacchi della Chiesa cristiana. Inscrivendosi nella tradizione del genere della visione dell’aldilà, il poeta riesce a praticare la sua auto-autorizzazione creativa che, come superamento letterario degli intertesti precedenti, serve alla sua stessa fama poetica e trascende artisticamente anche i confini dell’ortodossia.
Wer kommt heute in die Hölle?
Authors: Ott Christine
Published: November 2024

Riassunto

Prendendo spunto dalle celebrazioni dei centenari danteschi e dalle numerose pubblicazioni divulgative uscite in quest’occasione, l’articolo esamina le diverse strategie con cui la Commedia viene attualizzata per un pubblico giovane e contemporaneo. Si insiste poi sulla controversia riguardo ai contenuti percepiti, da alcuni (come la NGO Gherush92), come politicamente scorretti, da altri invece appropriati ai fini di una propaganda nazionalista e/o xenofoba. Nel dibattito pubblico e politico, infatti, Dante può essere appropriato sia dalla destra che dalla sinistra. Nell’ambito della ricerca universitaria, dantisti quali Marco Grimaldi hanno duramente criticato letture che cercano di mettere in rilievo gli aspetti più liberali della Commedia, opponendovi la visione di un Dante fortemente ideologico (se non addirittura fondamentalista) e la convinzione di un contenuto storicamente oggettivo dell’opera dantesca. Contro una tale visione, l’articolo presente chiama in causa le convinzioni dell’estetica della ricezione. Enfatizzando l’idea della lettrice come co-creatrice del significato di un testo, ogni lettura della Commedia è necessariamente attualizzante: non perché ne traspone necessariamente i contenuti in un contesto odierno, ma perché non può prescindere dalle conoscenze, dalle ansie, aspettative e speranze dell’oggi. Dopo aver brevemente accennato ad alcuni tentativi di attualizzare Dante (nell’ambito della riscrittura creativa e della critica) l’articolo propone un approccio attualizzante che non coincide con la pretesa di misurare il sistema di valori della Commedia con i valori delle odierne democrazie liberali. Si auspica, invece, il tentativo di una lettura che non si limiti al solo approccio storicizzante. Questo ha il vantaggio di accettare il testo di un’altra epoca nella sua alterità, nella sua incommensurabilità con i valori odierni. Ma il fatto è che la Commedia è un’opera letteraria che, come poche altre, ha avuto un impatto ben al di là della sua epoca. Lo ha avuto perché contiene elementi di interesse universale, che trascendono i confini temporali e culturali. Attualizzare non significa però salvare, dell’opera, quei granelli d'oro che appaiono indiscutibilmente preziosi allo sguardo di oggi. Piuttosto, dobbiamo relazionarci anche con gli aspetti che ci sembrano strani, inquietanti, scioccanti. È l’estraneità, l’infamia di Dante che ci sfida a riflettere su noi stessi, sui nostri valori, sulle nostre infamie.
Language change across the lifespan: The changing status of a local variant
Authors: Guðmundsdóttir Margrét
Published: November 2024

Three major studies on pronunciation were conducted in Iceland over a period of 70 years, including collection of real-time data. One subgroup of participants was interviewed as children in the 1940s, again as adults in the 1980s, and once again in the 2010s. Another subgroup was interviewed twice. By reanalysing raw data on participants in the first study the author was able to compare them with subsequent studies and trace individual developments, and thus examine lifespan changes over a long period. This article focuses on 62 participants from the two subgroups (47 people born in 1927–1932, and 15 born in 1963–1970), all from north-eastern Iceland, and a regional variant called ‘hard speech’ (harðmæli), i.e., the use of aspirated rather than unaspirated intervocalic plosives, comparing it with another north-eastern variant, so-called ‘voiced pronunciation’ (raddaður framburður), i.e., the use of voiced rather than voiceless sonorants before /p,t,k/. This reanalysis of the data of these seminal studies not only corroborates earlier findings that pronunciation can and does change among adult individuals, it also suggests (a) that such lifespan changes are more likely to happen in the first 2–3 decades of adulthood; and (b) that while ‘hard speech’ is fading as a local variant it shows signs of strengthening among individual speakers over their lifetime. This development takes place concurrently with attitudinal changes towards ‘hard speech’, which has come to be perceived as ‘clear pronunciation’.

Cell-Type–Specific Splicing of Transcription Regulators and
Ptbp1
by
Rbfox1/2/3
in the Developing Neocortex

Published: November 2024

How master splicing regulators cross talk with each other and to what extent transcription regulators are differentially spliced remain unclear in the developing brain. Here, cell-type–specific RNA-Seq analyses of the developing neocortex uncover variable expression of the Rbfox1/2/3 genes and enriched alternative splicing events in transcription regulators, altering protein isoforms or inducing nonsense-mediated mRNA decay. Transient expression of Rbfox proteins in radial glial progenitors induces neuronal splicing events preferentially in transcription regulators such as
Meis2
and
Tead1
. Surprisingly, Rbfox proteins promote the inclusion of a mammal-specific alternative exon and a previously undescribed poison exon in
Ptbp1
. Simultaneous ablation of
Rbfox1/2/3
in the neocortex downregulates neuronal isoforms and disrupts radial neuronal migration. Furthermore, the progenitor isoform of
Meis2
promotes
Tgfb3
transcription, while the
Meis2
neuron isoform promotes neuronal differentiation. These observations indicate that transcription regulators are differentially spliced between cell types in the developing neocortex. (The sex has not been reported to affect cortical neurogenesis in mice, and embryos of both sexes were studied without distinguishing one or the other.)

In this work, both pure and Mg-Cu co-doped zinc oxide thin films are prepared by sol-gel spin coating technique. Microscopic glass substrates are used for the synthesis of thin films. The thin films are examined by X-ray spectroscopy (XRD), photoluminescence spectroscopy (PL), scanning electron microscopy (SEM), ultraviolet-visible spectroscopy (UV-Vis), and energy dispersive X-ray analysis (EDX). The XRD reveals the hexagonal wurtzite phase of the films. The observed grain size is 23.34 nm to 15.94 nm for pure and Mg-Cu co-doped ZnO respectively. The SEM image shows an increase in grain size and a smoothing of the surface with Mg-Cu co-doping. The presence of Mg and Cu in the ZnO nanofilm is confirmed by EDX analysis. UV analysis shows an increase in percent transmittance with doping. The Tauc relation is used to estimate the band gap of the samples, and a significant shift in the band gap is observed. The photoluminescence diagram shows greater emission and surface defects with doping. The visible spectrum is completely covered by the low- level emission.

We pronounce a quick cost-effective, and one-of-a-kind single-step approach for fabricating paper-based devices by using correction pens instead of expensive materials. The highlighted areas were filled with Deposits from the correction pen and the surroundings were coated with wax, showing that will have a wide range of aqueous resistances. In the transverse direction, favorable natural convection occurs during the process along the axial direction of the fabricated paper channel. Due to its cost-effectiveness, the platform is believed to be ideally suited for chemical sensing and point-of-care applications, as well as diagnostics in resource-limited settings. We show that a lab-on-a-chip method based on paper can be used for colorimetric analysis to identify both qualitative and quantitative changes in milk caused by the presence of starch impurities. The challenges of sample storage, handling, and transport to the laboratory are circumvented by combining detection technology with smartphone imagery that permits on-site data collection. Diagnostic and sensing applications in low-resource settings, such as those seen in developing nations, can now use this technology.

Organic-inorganic hybrid perovskite solar cells have garnered significant attention due to their facile fabrication process and high photovoltaic conversion efficiency. The electron transport layer plays a crucial role in the carrier separation mechanism of perovskite solar cells, making it a focal point for enhancing cell performance. In this study, PbTiO3 was introduced into TiO2 mesoporous layers by modification and doping in order to optimize cell performance. Initially, the use of PbTiO3-modified mesoporous layers revealed issues such as non-uniform modification layers, low film coverage rates, and reduced light transmittance. These issues hindered the ability of PbTiO3 to facilitate carrier separation and resulting in suboptimal optimization effects. However, by utilizing PbTiO3-doped mesoporous layers for optimizing cell performance, we observed improved quality and higher light transmittance in the perovskite films. As a consequence of the improved carrier separation achieved by PbTiO3, the efficiency of the solar cell has been enhanced to 5.51%.

In this work, superhydrophobic coatings were prepared on circuit boards based on the susceptibility of circuit boards to harsh environments such as humidity and mold adhesion, leading to reduced service life. Firstly, cetyltrimethoxysilane and γaminopropyltriethoxysilane were used to modify zinc oxide nanoparticles with different particle sizes. Then polyurethane and modified nanoparticles were successively sprayed on the circuit boards with a spraying process, and the superhydrophobic coatings were finally produced. The impact of the zinc oxide mass ratio with different particle sizes, silane coupling agent content, and surface modifier content on the hydrophobicity of the coatings were investigated. The results show that when the mass ratio of zinc oxide (30nm) to zinc oxide (90nm) is 1:1, the silane coupling agent content is 12‰. The surface modifier content is 12‰, the hydrophobicity of the coating is the best, and its CA can be up to 169.5°, and its SA can be up to 2.8°. It exhibits good protection of circuit boards in the tests of adhesion, acid, and alkali corrosion resistance, self-cleaning performance, and anti-mold performance. Performance, so that the coating is in the future field of electronic equipment applications.

Zinc cobalt oxide nanostructures were synthesized by electrochemical deposition of zinccobalt alloy at various bath temperatures (15, 30, 45 and 60 ˚C) and its hydrothermal oxidation at 100 ˚C. X-ray diffraction pattern and Raman spectroscopy data reveals the formation of spinal structure of ZnCo2O4. Photoluminescence spectra of the samples exhibit broad peaks with a red shift in the emission energy. Diffused reflectance spectroscopy measured the band gap of the synthesized materials; band gap is 3.06, 3.03, 3.02 and 2.99 eV, for samples electrodeposited at 15, 30, 45 and 60 ˚C, respectively. Optical conductivity of synthesized materials decreases with increasing deposition layers while reflectance shows opposite trend. Thermoelectric set up measures the change in potential difference through synthesized materials when different temperatures are applied and an increment in potential were observed. Seebeck co-efficient and power factor are also studied as function of bath temperature.

DNA typing technologies make it possible to detect alleles and their frequencies in biochemical systems of proteins and enzymes, including specific PCR sequences, restriction enzymes and actually single nucleotide polymorphisms. The development of breed-specific SNPs is necessary for genotyping and mapping of associations with milk productivity traits, which will make it possible to identify the most valuable genotypes for their further use in selection and breeding work. The purpose of the study is to determine the allelic and genotypic frequencies, genetic diversity and polymorphism of hemoglobin (HB), ceruloplasmin (CP), posttransferrin (pTf), amylase (Am-1) and the receptor for vitamin D (calcitriol) (GS) to identify the relationship breed-specific features of their genetic structure. The results of the research revealed the influence of the breed of cows on their genetic structure according to the genetic-biochemical systems pTf, GS, HB, CP and Am-1. A clear influence of the genotype factor at the posttransferrin locus was observed, among the studied breeds of cows, on the manifestation of the content and amount of protein in milk. In addition, a probable effect of ceruloplasmin on the parameters of fat and protein in milk was established, depending on the breed of cows. The assessment of the genetic-biochemical system based on the amylase locus established a clear influence of the genotype on the manifestation of milk yield, milk fat and the amount of protein in milk. Thus, the use of polymorphism of individual loci of proteins and blood enzymes in the conduct of selection and breeding work will not only contribute to the improvement of breeding work, but also to the improvement of dairy cattle in general. Therefore, the perspective of breeding work with Holstein cattle should be the assessment of the diversity of the allelogen according to the polymorphic system of proteins and enzymes, which will allow to identify the best genotypes not only in terms of productivity, but also in genetic terms.

У статті визначено теоретичні погляди стосовно дефініцій «журналістика рішень» і «конструктивна журналістика» як медійних підходів, орієнтованих на пошук розв’язання суспільних проблем. Авторами розглянуто практику української журналістики рішень під час воєнного стану. Виокремлено тематичні домінанти висвітлення метатеми війни та повоєнного відновлення, схарактеризовано інструментарій, застосовуваний журналістами для унаочнення рішень, привертання уваги аудиторії.
За допомогою методів кейс-стаді та контент-аналізу було вивчено текстове й візуальне наповнення українського онлайн-видання «Рубрика», яке працює в напрямку журналістики рішень. Розроблена система категорій аналізу дозволила визначити, що в досліджуваному медіакейсі трендовими є теми фізичного й ментального здоров’я та військової сфери. При цьому героями й об’єктами матеріалів здебільшого є представники експертного середовища в різних напрямках, волонтери, військові та підприємці. Геополітичний контекст пошуку рішень у виданні зосереджено на внутрішньоукраїнському дискурсі, а тексти про залучення міжнародної підтримки є перспективними з огляду на розширення тематичних ракурсів аналізованого медіа.
Результати аналізу свідчать про те, що в «Рубриці» пошук рішень у розрізі метатеми війни здебільшого здійснюється через висвітлення діяльності волонтерських, благодійних і державних ініціатив. Оформлення розв'язання проблем, порушених у публікаціях видання, здійснюється за допомогою таких цифрових інструментів, як візуальне виокремлення в тексті ключових слів, цитат, списків порад, інструкцій і рекомендацій, а також перелінковки на зовнішні та внутрішні ресурси. З’ясовано, що перспективними засобами для «медіа рішень» залишається більш широке використання мультимедійного ілюстративного контенту: скриншотів, інфографіки, інтерактивних карт, аналітичних врізок-довідок, фото й відеоматеріалів, які увиразнюють пропоновані розв’язання, дозволяють розширити й диверсифікувати аудиторію.
