Metaphor Power in the US-China Trade War Discourse
Authors: Kalinin O. I.
Published: February 2024

The article studies the role of metaphor in modeling the enemy image in the US-China trade war discourse. Based on the metaphor power theory, speech impact of metaphors on cognitive, semantic and communicative levels is described. The cognitive level of metaphor power is manifested in the metaphors of different intensity, namely conventional and noval, semantic metaphor power is manifested in the metaphors that differ in semantics and language form, namely orientational, ontological and structural, and, finally, communicative metaphor power is associated with the metaphor’s position in the text structure. All the three levels of metaphor power can be identified quantitatively by metaphor power indices (MII – intensity index, MfTI – index of functional typology, MStI – index of the text structure). Indices are interpreted on the data of previously conducted case studies, which allows us to determine the degree of metaphor power. Proposed methodology also includes identification of the most typical metaphorical models that make it possible to describe direction and content of discursive conceptualization. News texts corpora representing the trade war have been studied, showing Chinese discourse being more influential with indicators of intensity and functional typology indices reflecting the emotionality and transformational nature of the metaphors used, while metaphors in American articles seem to be more aimed at rational and identification impact. The main target concepts in the studied texts were “trade war” as a new reality of bilateral relations between countries and the actors of these relations, the US and the PRC. In the trade war discourse, the image of trade war is created as a “fierce geopolitical battle” (China) or “inevitable economic confrontation” (USA). Metaphors are also used to make changes to the evaluative component of the concepts CHINA (as a thief and a fraudster in American discourse) and USA (as a gendarme with a baton in Chinese discourse) in order to form a certain attitude and cause-and-effect relationships in their audience.

Experience in Measuring Productivity of Suffix Morphemes in Chinese Military News Discourse Based on a Universal Measure
Authors: Korshunov D. S.
Published: February 2024

The article studies the issues of measuring derivational productivity of affixes. It considers the concept of productivity and its various aspects which can be quantified by corpus linguistics methods. In particular, it analyzes the measures of “expanding” and “potential” productivity by H. Baayen, and proposes a new formula for “universal” productivity on the basis of the analysis. These three productivity measures are applied to 80 Chinese suffix morphemes (suffixes and semi-suffixes) within a thematic collection of texts – Chinese media reports on military topics for 2019. The language material comprises 2066 texts (2.852.262 characters). The study resulted in three variants of the rating list for the most productive suffix morphemes of the Chinese military news discourse, which can be used for didactic and applied purposes. H. Baayen’s “expanding productivity” and the “universal productivity” proposed in the work showed a high correlation (0.85), while H. Baayen’s “potential productivity” correlates with them negatively. A meaningful analysis of the results also brings up a question of the appropriateness of using the “potential productivity” measure. Comparison of existing measures and the formula proposed in the work allow us to conclude that for an approximate assessment of the suffix morphemes productivity one can use the formula of “expanding productivity” by H. Baayen, which, despite relying only on the single word token (hapax legomenon) frequency, gives quite plausible results. To measure the suffix morphemes productivity more precisely, it is recommended to use the “universal productivity” formula proposed in this paper which takes into account a larger number of significant parameters (the number of hapax legomena with the estimated affix, the total type count with the given affix, and the average regular word token frequency of the estimated affix) and is more reasonable in this respect.
Ossifying fibroma of the ethmoid and sphenoid sinuses: A report of a rare case and literature review
Authors: Azab Mohammed A.
Published: February 2024

Background:

Fibro-osseous lesions include a variety of bone lesions with different clinical and histopathological features.

Case Description:

We report a case of cemento-ossifying lesion involving the left ethmoid and sphenoid sinus in a 17-year-old male patient. Computed tomography showed an expansile hyperdense lesion with sclerosed peripheral mantle epicentered on the left ethmoid and sphenoid sinus and extending into the left nasal cavity. Magnetic resonance imaging was done for preoperative planning. Transnasal endoscopic resection was performed and histopathological examination confirmed the diagnosis of ossifying fibroma (OF).

Conclusion:

Involvement of the ethmoid sinus with OF is a rare condition; therefore, we examined the literature for similar cases to highlight the possible clinical presentation and management. Endoscopic management is a safe, effective approach with a low rate of complications.

Mechanisms of intrauterine infection of the fetus
Authors: Синюкова Т.А. , Коваленко Л.В. , Белоцерковцева Л.Д.
Published: February 2024

Одной из главных причин патологического течения беременности и родов выступает внутриутробная инфекционная патология. Трансплацентарное инфицирование плода считается одной из наиболее вероятных причин врождённых пороков развития, что создает медицинские и социальные проблемы. Клиническая картина внутриутробной инфекции во время беременности не всегда имеет специфические черты, что затрудняет её диагностику. Передача инфекционного возбудителя во время беременности от матери к плоду во многом зависит от функционирования иммунной системы женщины. Основными путями проникновения инфекции от матери к плоду является восходящий и гематогенный путь. Смешанный путь инфицирования фетоплацентарного комплекса в литературе недостаточно освещен. В эпоху так называемой «иммунодефицитной прослойки населения» патофизиологические механизмы формирования инфицирования плода остаются не изученными, поэтому исследования в этом направлении являются актуальными. В данном обзоре отражен современный взгляд на этапы патогенеза внутриутробного инфицирования плода. Приведены актуальные точки зрения об этиологии, механизме восходящего, гематогенного и смешанного путях внутриутробного инфицирования. Рассмотрены последствия влияния инфекции на здоровье плода.

Intrauterine infectious pathology is one of the main causes of the pathological course of pregnancy and childbirth. Transplacental infection of the fetus is considered one of the most likely causes of congenital malformations, which creates medical and social problems. The clinical picture of intrauterine infection during pregnancy does not always have specific features, which makes it difficult to diagnose. Transmission of an infectious pathogen during pregnancy from mother to fetus largely depends on the functioning of a woman’s immune system. The main routes of infection from the mother to the fetus are the ascending and hematogenic pathways. The mixed pathway of infection of the fetoplacental complex is insufficiently covered in the literature. In the era of the so-called “immunodeficiency stratum of the population”, the pathophysiological mechanisms of fetal infection formation remain unexplored, therefore, research in this direction is relevant. This review reflects the current stages of the pathogenesis of intrauterine infection of the fetus. The current points of view on the etiology, mechanism of ascending, hematogenic and mixed pathways of intrauterine infection are presented. The effects of infection on fetal health are considered.

Published: February 2024

Посттравматическое стрессовое расстройство (ПТСР) развивается при тяжёлом стрессе, обычно вызванном угрожающими жизни или травмирующими ситуациями. ПТСР часто провоцирует развитие серьёзных как психических, так и соматических заболеваний. Несмотря на то, что 50-60% людей хотя бы раз в жизни пережили травмирующие события, у большинства из них ПТСР не развивается благодаря активности эндогенных протекторных систем. Они включают в себя системы антиоксидантов, белков теплового шока, простагландинов, оксида азота и другие. Наиболее известным и хорошо изученным способом повышения активности эндогенных протекторных систем является адаптация к периодической нормо- или гипобарической гипоксии (АГ). В обзоре представлены данные о способности АГ ограничивать повреждающие эффекты ПТСР в центральной нервной системе и висцеральных органах и обсуждаются возможные механизмы этой защиты.

Post-traumatic stress disorder (PTSD) develops after severe stress generally induced by life-threatening or traumatizing situations. PTSD frequently provokes serious psychic and smatic diseases. Although 50-60% of people have been exposed to traumatic events at least once during their lifetime most of them do not develop PTSD due to the activity of endogenous defense systems. These systems include antioxidants, prostaglandins, nitric oxide, heat shock proteins and others. The most known and studied method for enhancing the activity of endogenous defense systems is adaptation to intermittent normo- or hypobaric hypoxia (AH). This review focuses on the ability of AH to restrict detrimental effects of PTSD on the central nervous system and visceral organs and addresses possible mechanisms of the AH protection.
Heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1) as a pathogenetically significant drug target for oncology therapy (molecular docking of irinotecan and doxycycline)
Authors: Волкова О.О. , Шитяков С.В. , Кравцов В.Ю.
Published: February 2024

Актуальность. В последние годы гиперэкспрессия и накопление гетерогенного ядерного рибонкулеопротеина А2В1 (hnRNPA2B1) в новообразованиях рассматривается как новая типовая реакция, развивающаяся в ходе злокачественной прогрессии, а сам hnRNPA2B1 становится патогенетически значимой мишенью для противоопухолевых препаратов. Целью нашего исследования стало теоретическое моделирование in silico методом молекулярного докинга взаимодействий противоракового препарата иринотекана и антибиотика тетрациклинового ряда доксициклина с белком hnRNPA2B1. Результаты проведённых докингов указывают на ещё один механизм дезактивации hnRNPA2B1 за счет связывания лигандов с белком вместо молекул РНК. Среди наиболее вероятных карманов (P0–P4) наилучшее сродство наблюдалось в карманах P0 и P4, принадлежащих к доменам RRM1 и RRM2 соответственно. Оказалось, что сродство иринотекана (ΔG = –10,36 ккал/моль) выше, чем сродство доксициклина (ΔG = –8,20 ккал/моль). Полученное значение энергии связывания доксициклина указывает на образование комплекса hnRNPA2B1–доксициклин, что делает дальнейшее рассмотрение доксициклина как таргетного противоопухолевого препарата перспективным. Заключение. Рассчитанные значения энергии связывания указывают на фармакологически значимое образование комплексов hnRNPA2B1–иринотекан и hnRNPA2B1–доксициклин, что указывает на ещё один плейотропный противоопухолевый эффект этих препаратов.

Context. In recent years, overexpression and accumulation of heterogeneous nuclear ribonculoprotein A2B1 (hnRNPA2B1) in neoplasms has been considered as a new typical reaction on cancer progression. Therefore, hnRNPA2B1 is a pathogenetically significant target for antitumor drugs. The aim of our study was the theoretical modeling in silico of the interactions of the anti-cancer drug irinotecan and the tetracycline antibiotic doxycycline with the hnRNPA2B1 protein. Results. The affinity of doxycycline and irinotecan to hnRNP A2B1 was calculated by molecular docking method. According to the results, affinity of irinotecan (ΔG = –10.36 kcal/mol) is higher than the affinity of doxycycline (ΔG = –8.20 kcal/mol). However, the value of the binding energy of doxycycline indicates the formation of the hnRNPA2B1 – doxycycline complex, which makes further studies of doxycycline as an anticancer drug potentially interesting. Conclusion. The binding energies (ΔG) of irinotecan and doxycycline to the target RNA-binding protein hnRNPA2B1 obtained by molecular modeling were -10.36 kcal/mol and -8.20 kcal/mol respectively. The calculated binding energy values indicate the pharmacologically significant formation of hnRNPA2B1–irinotecan and hnRNPA2B1–doxycycline complexes, which indicates another anti-cancer pleotropic effect of these drugs.
Metal-organic polyhedron from flexible tetrakis(thiobenzyl-carboxylate)-Tetrathiafulvalene

Published: February 2024

The synthesis of crystalline self-assembled materials starting from building blocks with a large degree of freedom is challenging. Furthermore, incorporating redox-active moieties in self-assembled metal organic polyhedra is of the outmost interest to modulate the properties of the cavity through redox stimuli. Herein is presented the synthesis of a novel electroactive ligand bearing four coordinating moieties around an S-alkylated tetrathiafulvalene (TTF) scaffold. The redox behavior of the ligand is similar to a tetra-S-alkylated TTF. In the solid state, it presents a densely packed H-bonded 1D polymeric structure. Upon reaction with Cu(OAc)2 in the presence of dimethylformamide or dimethylacetamide, two novel M4L4-type metal-organic polyhedra (MOPs) bearing paddlewheel metal clusters as connecting nodes are obtained. The structural features and electrochemical properties of the ligand and the MOPs are devised. Both MOPs adopt the same structure characterized by a tetrahedral arrangement of the four TTF moieties.
Elucidating Nonradiative Decay in Deep Near-Infrared Lumiphores: Leveraging New Design Principles to Develop a Telecom Band Organic Dye Laser

Published: February 2024

Near-infrared (NIR) lumiphores have been targeted for biological and technological applications; however, these dyes suffer from exponentially decreasing quantum yields as their energy gaps decrease. The accepted model of this phenomenon invokes excited-state coupling to C–H modes. Reduction of these modes has been a popular design strategy to design bright NIR lumiphores, but definitive experimental validation of this strategy is lacking. Here we systematically evaluate the role of C–H modes in nonradiative relaxation through isotopic labeling of a NIR-emitting complex. Perdeuteration of the emissive molecule indicates that C–H modes do not contribute significantly to nonradiative relaxation, in direct contrast with accepted models. Our results instead suggest that skeletal modes may play a larger role. This suggests that minimizing scaffold size is a more promising route for bright NIR lumiphores. We demonstrate the promise of such strategies through the development of the reddest organic-based laser dye yet reported.

To understand the fracture behaviour in battery materials, X-ray computed tomography (X-ray CT) has been employed widely and has become the primary technique for non-destructive particle analysis. Cracking is known to cause decline in cell performance of polycrystalline NMC811 as it exposes new surfaces for parasitic electrolyte reactions and disconnects active material from the electrode matrix. First cycle crack formation has been documented previously; however, definitive electrochemically induced particle fracture can be difficult to assess due to complicated sample preparation methods and the availability of high-resolution X-ray imaging. Here we present an operando X-ray CT technique that enables accurate observation of fracture behaviour as the particles are de-/lithiated. We uncover a non-linear relationship between fracture behaviour and the cell voltage, and evidence of particle reformation as re-lithiation occurs, we also see the effect multiple cycles have on the severity of cracks. Using a grey level analysis algorithm for fracture detection, we have expedited the damage evaluation of thousands of particles throughout the electrochemical process to successfully understand crack initiation, propagation, and eventual partial particle restoration on a large statistical scale. In addition we explored the effects of continued volumetric hysteresis on particles’ damage fingerprints. For the first time, we demonstrate the complex plurality of fracture behaviour in commercial lithium ion battery materials, that will help to design mitigation strategies to combat the effects of particle fracture.
High-pressure phases of boron pnictides BX (X = As, Sb, Bi) with quartz topology from first principles
Authors: Solozhenko Vladimir L. , Matar Samir F.
Published: February 2024

The superdense hexagonal boron pnictides BX (X = As, Sb, Bi), whose structures are formed by distorted tetrahedra and characterized by a quartz-derived (qtz) topology, have been predicted from first principles as potential high-pressure phases. From full geometry structure relaxation and ground state energy calculations based on quantum density functional theory (DFT), qtz BX were found to be mechanically (elastic constants) and dynamically (phonons) stable. From the energy-volume equations of state, at experimentally accessible pressures qtz boron pnictides were found to be more energetically favorable than corresponding cubic zinc-blende phases with diamond-like (dia) topology. According to the electronic band structures, the zinc-blende BX have larger band gaps than the qtz phases, which can be attributed to the higher covalence of the latter. A metallic behavior is only observed for qtz BBi, which is related to the dynamic instability as it follows from the phonon band structure.

Crystallophores are lanthanide complexes that have demonstrated outstanding induction of crystallization for various proteins. This article explores the effect of tailored modifications of the crystallophore first generation and studies their impact on the nucleating properties, and protein crystal structures. Through high-throughput crystallization experiments and dataset analysis, we evaluated the effectiveness of these variants, in comparison to the first crystallophore generation G1. In particular, the V1 variant, featuring a propyl-3-ol pendant arm, demonstrated the ability to produce new crystallization conditions for the proteins tested (hen-egg white lysozyme, proteinase K and thaumatin). Structural analysis performed in the case of hen egg-white lysozyme along with Molecular Dynamics simulations, highlights V1's unique behavior, taking advantage of the flexibility of its propyl-3-ol arm to explore different protein surfaces and form versatile supramolecular interactions.

Published: February 2024

In the pursuit of terminal tin chalcogenides, heteroleptic stannylenes bearing terphenyl and hexamethyldisilazide ligands were reacted with carbodiimides to yield the respective guanidinato complexes. Further supported by quantum chemical calculations, this revealed that the iso-propyl-substituted derivative provides the maximum steric protection achievable. Oxidation with elemental selenium produced monomeric terminal tin selenides with four-coordinate tin centres. In reactions with N2O as oxygen transfer reagent, silyl migration towards putative terminal tin oxide intermediates gave rise to tin complexes with terminal –OSiMe3 functionality. To prevent silyl migration, the silyl groups were substituted for cyclohexyl moieties. This analogue exhibited distinctively different reactivities towards selenium and N2O, yielding a tetraselenastannolane and chalcogenide-bridged dimeric compounds, respectively.

This study explores the innovative application of machine learning techniques in monitoring and analyzing the workflow associated with earthquakes. The primary objective is to enhance the accuracy and efficiency of earthquake detection, prediction, and response mechanisms the development of machine learning technology enables more robust real-time earthquake monitoring through automated implementations. However, the application of machine learning to earthquake location problems faces challenges in regions with limited available training data. This paper proposes a machine learning-based approach to monitor seismic workflows efficiently. We apply various Machine Learning algorithms, including deep learning neural networks and decision trees, to process and interpret vast amounts of seismic data. These algorithms were trained on historical earthquake records to identify patterns and anomalies that precede seismic events. Our approach not only focused on the detection of seismic activities but also on the prediction of potential aftershock locations and magnitudes. Earthquake monitoring and response systems play a crucial role in mitigating potential damages and ensuring rapid response to seismic events. Traditional methods rely on sensor networks and manual analysis, often leading to delays in detection and response. The system leverages real-time data from seismic sensors, incorporating advanced machine learning algorithms for data analysis and pattern recognition. By employing deep learning models, such as convolution neural networks (CNNs) and recurrent neural networks (RNNs), the system can detect and classify seismic activities accurately. Additionally, anomaly detection techniques enable the identification of unusual seismic patterns that might indicate impending earthquakes or aftershocks. The system integrates geographical information systems (GIS) to map the seismic activities spatially, aiding in the visualization and understanding of seismic patterns across regions. The machine learning models are trained on historical seismic data to enhance their predictive capabilities and adaptability to varying seismic behaviors. This proposed system offers a real-time monitoring solution that can assist in early earthquake detection, accurate event classification, and timely response coordination. Its ability to continuously learn from incoming data ensures adaptability to changing seismic behaviors, thereby improving overall efficiency and reliability in earthquake monitoring workflows.

The prevalence of stunting still varies between districts, even though it shows a decreasing trend nationally. Variations in the correlation of specific determinants are characteristic of each region that must be considered when designing stunting control strategies, considering the significant future impacts. The study aims to identify specific determinants of stunting among toddlers between districts in Lampung Province. With an ecological design, the study uses aggregate data from the Indonesian Nutrition Status Study Report 2022 and Welfare Statistics of Lampung Province 2022. The analysis was carried out in stages with the Moran's Index and Local Moran's Index (LISA), using ArcMap and GeoDa software. Based on the analysis results, there are three districts with stunting prevalence above the national average and ten districts above the provincial average. Comparison year over year (YoY) shows that the two districts have increased from low to high or very high. We also found six variables specifically correlated with the prevalence of stunting: access to safe drinking water and sanitation, poverty, birth attendant, age at pregnancy, and length of breastfeeding. Increasing and improving specific determinants is an essential step in designing control strategies.

Voltage stability and power loss minimization with UPFC using heuristic and hybrid heuristic methods
Authors: Siva Subramanyam Reddy Rachapalli
Published: February 2024

Present-day power systems have highly complex and stressed operating conditions owing to insufficient reactive power to meet the required power demand. This leads to increased real power and reactive power losses, as well as voltage instability within a power system. To achieve the flexible operation of the power system, Flexible Alternating Current Transmission System (FACTS) devices have been employed. The optimal location of FACTS devices influences the system's performance and significantly affects line/bus reactive power flows. Consequently, the line or bus voltage profiles have been improved, leading to a reduction in power losses. Particle Swarm Optimization (PSO) heuristic methods and HFPSO Hybrid heuristic methods have been used to identify the weakest bus/branch for the suitable placement of UPFC devices, improving voltage stability. This paper discusses a more significant reduction in power losses in a MATLAB environment. Flexible Alternating Current Transmission System (FACTS) devices address reactive power challenges in power systems and enhance operational flexibility. Strategic placement using Particle Swarm Optimization (PSO) and HFPSO Hybrid methods identifies weak points, optimizing Unified Power Flow Controller (UPFC) placement for improved voltage stability. UPFC integration strategically reduces real and reactive power losses, improving power transmission efficiency. This enhances line and bus voltage profiles, addressing instability and significantly reducing overall power losses. The paper offers a detailed analysis of the power system, highlighting the synergy between FACTS devices, heuristic optimization, and power loss reduction. Simulations in MATLAB validate the proposed methodology, demonstrating a noteworthy improvement in power system performance.

Authors: Rajkumar K.
Published: February 2024

Arithmetic Logic Units (ALUs) are key elements within processors, executing a variety of operations including multiplication, division, addition, and subtraction. Among these, multiplication stands out as the most frequently utilized function within ALUs. This study presents an innovative MSI-interfaced multiplier architecture designed for integration into a multi-precision floating-point multiplier framework. This novel architecture offers configurations for 24-bit, 53-bit, 113-bit, and 237-bit binary operations, corresponding to single, double, quadruple, and octuple precision modes of floating-point computation. Notably, it enhances throughput by accommodating the multiplication of multiple batches of inputs with each operation initiation, surpassing existing binary multiplication systems. A unique Mantissa Similarity Investigation (MSI) implementation is developed and integrated into the binary multiplier architecture. Comparative analysis of the path delay in 24-bit mode against existing 24-bit multipliers demonstrates that the novel MSI-interfaced binary multiplier architecture, with and without MSI, exhibits reduced path delay compared to all existing systems, as anticipated.
