Exploration of the Teaching Reform of Computer Composition Principles with Ideological and Political Education at Anqing Normal University

The teaching mode of the Computer Composition Principles includes theoretical and practical teaching. At present, there is a problem of inconsistency in the teaching content of the two methods in our school. To this end, this paper conducts online and offline hybrid teaching based on the learning platform and the virtual simulation experiment platform, and cleverly applies ideological and political elements to theoretical and practical teaching to practice ideological and political education. Finally, the combination of theoretical and practical teaching modes can further help students firmly grasp the core knowledge points and improve the teaching quality and level of this course.

An empirical study of feature extraction for Hubei folk art of carved paper-cutting.

Excellent traditional culture is the root and soul of a nation, which is the carrier of historical precipitation and continuous development. In this aspect, Hubei folk art of carved paper-cutting has important cultural value and historical significance in the composition of Chinese traditional culture, which is a national intangible cultural heritage under key protection and urgently needs to be carried forward. This paper carried out an empirical study using the survey and comparative analysis methods on the feature extraction for Hubei folk art of carved paper-cutting. Through investigation and comparative analysis of vast artworks of Hubei carved paper-cutting, the classics are selected as the representative to extract the regional characteristics, the artistic values, and the composition and modelling methods. Results indicate that the common features exist on the artistic values in beautification of life and education, the composition principles of central-based, symmetry, balanced or conformal, and the modelling techniques using Yin and Yang carving, unobstructive perspective, distortion and exaggeration. However, the regional features in cultural expression, folklore communication, modelling skills are apparent and strong interlinked with the regional historical development in social activities, labor productivity and surrounding environment. This study provides a multi-dimensional perspective for the modern inheritance and development of traditional Hubei artworks of carved paper-cutting with specified characteristics.

Fundamental Body Composition Principles Provide Context for Fat-Free and Skeletal Muscle Loss With GLP-1 RA Treatments.

During weight loss, reductions in body mass are commonly described using molecular body components (eg, fat mass and fat-free mass [FFM]) or tissues and organs (eg, adipose tissue and skeletal muscle). While often conflated, distinctions between body components established by different levels of the 5-level model of body composition-which partitions body mass according to the atomic, molecular, cellular, tissue/organ, or whole-body level-are essential to recall when interpreting the composition of weight loss. A contemporary area of clinical and research interest that demonstrates the importance of these concepts is the discussion surrounding body composition changes with glucagon-like peptide-1 receptor agonists (GLP-1RA), particularly in regard to changes in FFM and skeletal muscle mass. The present article emphasizes the importance of fundamental principles when interpreting body composition changes experienced during weight loss, with a particular focus on GLP-1RA drug trials. The potential for obligatory loss of FFM due to reductions in adipose tissue mass and distribution of FFM loss from distinct body tissues are also discussed. Finally, selected countermeasures to combat loss of FFM and skeletal muscle, namely resistance exercise training and increased protein intake, are presented. Collectively, these considerations may allow for enhanced clarity when conceptualizing, discussing, and seeking to influence body composition changes experienced during weight loss.

Horizontal shaking table tests on a four-story prototype structure using multi-dimensional earthquake isolation and mitigation devices

Three-dimensional isolation system (3DIS) has been increasingly applied to civil structures with small height-width ratios, but is rarely employed in the multistory and high-rise buildings due to the lack of efficient control strategy for the rocking effect. In this paper, a simplified analysis model of 3DIS was established firstly to bring insights into the coupled motion mode caused by the rocking effect, and the influence of damping ratio and height-width ratio on the modal frequency was revealed. Then, aimed at weakening rocking motion and improving the seismic isolation efficiency, a novel multi-dimensional earthquake isolation and mitigation device (MEIMD) was proposed, and both the design composition and design principle were given in detail. To validate the effectiveness of MEIMDs, a full-scale four-story frame with a height of 13.05 m and a weight of 70 tons was produced for horizontal shaking table tests. The experimental results indicated that after adopting MEIMDs, the first-order modal frequency was 1.7 Hz, with 68% decrease compared with that of the prototype structure, and the first-order modal damping ratio was above 0.23, about eight times that of the prototype structure. Moreover, the horizontal peak acceleration was significantly decreased for each floor with a maximum reduction of 49%, while the maximum horizontal displacement and rocking response were obviously lower than the limit value specified by building codes. Therefore, the MEIMDs can not only efficiently isolate the earthquake energy, but also ensure the sufficient dynamic stability of the system. This study sheds light on the real coupled horizontal-rocking response of the base isolation system with MEIMDs, and can promote the development and application of 3DIS in multistory and high-rise buildings.

Multi-Objective Bayesian Optimization for Laminate-Inspired Mechanically Reinforced Piezoelectric Self-Powered Sensing Yarns.

Piezoelectric fiber yarns produced by electrospinning offer a versatile platform for intelligent devices, demonstrating mechanical durability and the ability to convert mechanical strain into electric signals. While conventional methods involve twisting a single poly(vinylidene fluoride-co-trifluoroethylene)(P(VDF-TrFE)) fiber mat to create yarns, by limiting control over the mechanical properties, an approach inspired by composite laminate design principles is proposed for strengthening. By stacking multiple electrospun mats in various sequences and twisting them into yarns, the mechanical properties of P(VDF-TrFE) yarn structures are efficiently optimized. By leveraging a multi-objective Bayesian optimization-based machine learning algorithm without imposing specific stacking restrictions, an optimal stacking sequence is determined that simultaneously enhances the ultimate tensile strength (UTS) and failure strain by considering the orientation angles of each aligned fiber mat as discrete design variables. The conditions on the Pareto front that achieve a balanced improvement in both the UTS and failure strain are identified. Additionally, applying corona poling induces extra dipole polarization in the yarn state, successfully fabricating mechanically robust and high-performance piezoelectric P(VDF-TrFE) yarns. Ultimately, the mechanically strengthened piezoelectric yarns demonstrate superior capabilities in self-powered sensing applications, particularly in challenging environments and sports scenarios, substantiating their potential for real-time signal detection.

Античные маскароны в системе смыслов русской архитектуры XIX — начала ХХ века

The article discusses the basic semantic and compositional principles of the location of ancient-themed mascarons in the space of the Russian architecture of the 19th — early 20th centuries on the example of buildings in Moscow and St Petersburg. They have appeared in the focus of the search for artistic expression by Russian sculptors and architects. Nevertheless, mascarons have never been the subject of specialized scientific research. The accents they bring to the figurative concept of structures are very instructive for understanding the system of meanings of some works of Russian architecture. All this determines the relevance of addressing this issue. The study uses formal stylistic and comparative methods of analysis.

Comparing session type systems derived from linear logic

Session types are a typed approach to message-passing concurrency, where types describe sequences of intended exchanges over channels. Session type systems have been given strong logical foundations via Curry-Howard correspondences with linear logic, a resource-aware logic that naturally captures structured interactions. These logical foundations provide an elegant framework to specify and (statically) verify message-passing processes.In this paper, we rigorously compare different type systems for concurrency derived from the Curry-Howard correspondence between linear logic and session types. We address the main divide between these type systems: the classical and intuitionistic presentations of linear logic. Over the years, these presentations have given rise to separate research strands on logical foundations for concurrency; the differences between their derived type systems have only been addressed informally.To formally assess these differences, we develop πULL, a session type system that encompasses type systems derived from classical and intuitionistic interpretations of linear logic. Based on a fragment of Girard's Logic of Unity, πULL provides a basic reference framework: we compare existing session type systems by characterizing fragments of πULL that coincide with classical and intuitionistic formulations. We analyze the significance of our characterizations by considering the locality principle (enforced by intuitionistic interpretations but not by classical ones) and forms of process composition induced by the interpretations.

A historic, technological, systematic, environmental, and economic introduction of hydro power

Hydropower is a clean and sustainable energy source that generates electricity by utilizing the potential energy of flowing water for energy conversion. It produces 16% of the worlds electricity and is the most widely used renewable energy source. In most cases, hydropower plants are built on rivers or other bodies of water that vary widely in elevation. The basic concept is to use dams or other structures to create reservoirs at higher altitudes and then release the water through turbines to generate electricity. Renewable energy has become the future development trend, and the amount of coal, oil, and natural gas has been drastically reduced due to human exploitation in the past few decades. This report presents the history of hydropower development since the Han Dynasty; the working mechanism of hydropower, such as its composition and basic physical principles; the physical construction of hydropower and the overall economic system; and the impact of hydropower on the environment and economy, mainly on ecology and global climate.

Technology and architectural expression in France and Slovenia

The review concludes with a school building in Slovenian territory that features an interesting wooden structure, which determines one of the compositional principles of the entire project.

Variable agentivity: Polysemy or underspecification

Many English verbs typically used agentively allow non-agentive uses. Some recent approaches assume such verbs are unspecified for agentivity, although in principle, polysemy is also an option. We demonstrate the complexity of variable agentivity through an in-depth examination of the English verb sweep, which shows variable agentivity due to both underspecification and motivated polysemy. Drawing on corpus data, we identify two senses for sweep, each with unique argument realization options and interpretive properties. The prototypical uses of this verb, which involve the use of a broom, are obligatorily agentive; however, we claim they instantiate a specialized sense. We argue that the verb’s basic sense, which underlies all its other uses, is unspecified for agentivity, being found with agentive and non-agentive subjects. We formulate event structures for both senses that encode the grammatically relevant components of meaning common across all the verb’s uses: an entity moves along a surface while imparting a force via contact with it. We show that the event structure for the specialized sense, which fixes the moving entity to be a broom, is derived via established processes involving the lexicalization of instruments and routine goal-oriented activities. We demonstrate how the argument realization options and interpretive properties that the verb shows in each sense emerge from applying established principles of argument realization and semantic composition to these event structures.

Design of Ni-rGO reinforced Sn2.5Ag0.7Cu0.1Ce composite solder based on micro-alloying and composite principles: Microstructure and properties

Based on the principles of micro-alloying and composite, the graphene reinforced Sn2.5Ag0.7Cu0.1Ce composite solder was designed. Ni nanoparticle-modified reduced graphene oxide (Ni-rGO) was prepared by thermal decomposition method, and the powder-melting method was proposed for the first time to prepare Ni-rGO reinforced Sn2.5Ag0.7Cu0.1Ce composite solder. The microstructure, wettability, electrical resistivity, and mechanical properties of the composite solder were systematically studied. Results indicated that the Ni nanoparticles uniformly adhered to the rGO with a size of 26.3 nm. The effective incorporation of Ni-rGO into the solder matrix was achieved. The result broke the technical difficulty that graphene cannot be effectively added to low melting point metals. With the addition of Ni-rGO, the grain size gradually decreased, and the eutectic structures increased. Deep etching results revealed that columnar β-Sn was stacked from layered β-Sn, the addition of 0.05 wt% Ni-rGO led to an increase in sheet-like Ag3Sn within the eutectics. Additionally, Ni-rGO was found at the grain boundaries of composite solder, serving as nucleation sites for Ag3Sn and Cu6Sn5. At an addition of 0.05 wt%, the tensile strength reaches a maximum of 58.1 MPa, with elongation of 33.8%, surpassing the strength of commercial Sn3.0Ag0.5Cu solder. Therefore, the high-strength and tough composite solder was obtained. This study offered a new approach for the development of low-melting-point composite materials.

‘부분의 독자성’ 개념의 재조명과 그 확장적 활용 가능성

This study re-examines “independence of the part,” a key concept in explaining the narrative structure, compositional principles, recognition of reality, and aesthetics of pansori. Additionally, it explores how this concept can be used extensively today. To this end, this study first discusses the meaning categories of “independence of the part” when it was first created in 1969, and the problems that have been pointed out regarding this concept since then, including a proposal of the concept of “maximizing of the scene,” and why the concept of “independence of the part” is still valid. Furthermore, this study considers what premises are required to use this concept more effectively in the future. In an era abundant with cultural content, when the creative succession of pansori is required, this study suggests through three main aspects how “independence of the part” can be effectively utilized: as a channel for raising critical question about the social reality; a channel for reflecting contemporary elements of interest; and as a channel for experimenting with new versions and repertoires. It confirms that “independence of the part” has the power to make the meaning of the pansori text open to various interpretations, ensuring pansori remains a living heritage rather than just a remnant of past cultural heritage. Furthermore, it is crucial for efficiently eliciting other content. In the 21st century, Korean Wave and the rise of K-contents have attracted attention worldwide. Nevertheless, serious consideration of “Korean storytelling” seems necessary for sustainable development and strong competitiveness. The final suggestion is that “independence of the part” can function as a key principle and qualification of such Korean storytelling. It is hoped that the discussion presented here will serve as an opportunity to actively pay attention to the potential of “independence of the part” in the creation, criticism, and research of pansori and other Korean story contents today.

Mechanism and experimental investigation on the formation of micro‐triangle stepped jet in composite spinning solution

AbstractIn the field of nanotechnology, rotary jet spinning technology has garnered attention due to its unique advantages in fabricating composite nanofibers. The composite nanofibers prepared using this technology exhibit exceptional purity, uniformity, and consistency, thereby enhancing reliability and controllability in practical applications. During the process of rotary jet spinning, the spinning solution flows into the nozzle and converges at a micro‐triangle under the combined influence of centrifugal force, viscous force, surface tension, and gravity. Stepped jet refers to the flow phenomenon occurring within a channel with a gradually decreasing cross‐sectional area. In this process, an increase in the flow velocity of the composite spinning solution aids in stabilizing stretching at the micro‐triangle which is crucial for forming continuous jets. This article analyzes cone formation mechanisms for composite spinning solutions and stepped jet principles while establishing corresponding models that reflect relationships between solution velocity magnitude and parameters such as rotational speed, concentration, and nozzle diameter. Finally, polyethylene oxide (PEO)/polyvinylpyrrolidone (PVP) composite nanofibers were prepared using a rotary jet spinning device where experimental investigation focused on examining how parameters such as rotational speed, solution concentration, and nozzle diameter impact motion of spinning solution within micro‐triangle.Highlights Preparation of PEO/PVP composite nanofibers by rotary jet spinning. Presentation of cone formation mechanisms for composite solutions. The stepped injection principle was proposed. Modeling of composite solution motion. Rotational speed, solution concentration, and nozzle diameter impact motion.

Don’t imagine junk! Positive conceivability and modal illusion in mereology

There is a widespread practice of using evidence obtained from conceiving/imagining for establishing possibility claims. As a case study. I offer a critical reconstruction of an influential conceivability argument, Bohn’s (Philosophical Quarterly 59:193-201, 2009a, Analysis 70:296–298, 2009b, Analysis 70:296-298, 2010) argument for junk (there are proper parts forming wholes, but there is no whole that is not a proper part itself). The most influential scenario used by Bohn and his successors is purported to be junk but not ensured to be junk. This finding calls for an explanation. I distinguish ways of conceiving/imagining that are insufficient to establish modal claims from positive conceiving/imagining, which is more promising. Positive conceiving/imagining often works by a partial structural isomorphy to its target, and it is sufficiently detailed. In order to be sufficiently detailed, it has to properly integrate theoretical considerations. I outline a concern about extant ways of conceiving/imagining junk: they do not yet include a metaphysical understanding of what it takes for there to be proper parts and wholes without a whole that is not a proper part itself, for instance in terms of a non-gerrymandered principle of composition.

Analysis of the approaches to protection against interference of UAV satellite navigation receivers.

The main approaches to the construction of signal receivers of global satellite navigation systems of unmanned aerial vehicles, protected from the influence of artificially created interference, are considered. Such systems are equipped with multi-element phased antenna arrays and devices of controlled reception pattern antenna. In the process of processing the received information signal by the Controlled Reception Pattern Antenna device. the selection of interference and their suppression (compensation) is ensured, which is equivalent to the formation of dips in the spatial pattern of the antenna array at the corners that correspond to the directions of the interference sources. The basic principles of the implementation of the adaptive algorithm for processing the received information signal are given. The design and composition of the navigation receiver of the «Orlan-10» unmanned aerial vehicle equipped with a Controlled Reception Pattern Antenna device is considered. A conclusion was made regarding the fundamental possibility of creating a domestic navigation receiver with a Controlled Reception Pattern Antenna device. In the future, it is envisaged to deploy works on the creation of Controlled Reception Pattern Antenna devices with a greater number of antenna elements and the use of optimization principles of the quantitative composition of adaptation operations, in order to ensure the performance of these devices with a greater number of simultaneously enabled sources of interference and higher levels of their signal power.

Odes to Miami

This paper investigates ›Zip Odes‹, a format developed for the O, Miami poetry festival, as an example of sociopoetic practices between the urban and digital space. Zip Odes are short poems written by residents that transform their zip code »into an occasion for place-based, lyrical celebration« (festival website). The Zip Ode’s composition principle is based on the number in the author’s zip code, and it is unlike traditional verse as words rather than syllables are counted. Each year, dozens of poems are displayed in the streets and performed in front of audiences. Further performances take place on the festival’s Instagram page, where written odes are animated in serial form or presented as video clips recited by the poets. After introducing the context of the O, Miami poetry festival, the paper will take a sociocultural perspective to discuss the Zip Ode as a popular adaptation of a classical lyrical genre. In the literary tradition, odes are song-like poems expressing strong feelings, particularly admiration, and addressed to sublime nature or an abstract entity. Here, they are directed at a place, a neighborhood, or a city. By performing a textual examination of exemplary Zip Odes, this paper will analyze the form and themes of the genre before discussing its various presentation formats. The paper sets the festival concept and, in particular, this innovative poetry format in relation to the notion of ›lyric address‹ and considers it as a practice of place-making.

油莎豆联合收获机用脱粒清选装置设计与试验

In response to the challenges of difficult separation and incomplete cleaning during the mechanized harvesting of Cyperus esculentus L., a combined threshing and cleaning device consisting of a fruit-picking roller, a cleaning belt, and an air-screening system was designed. The structure and working principle of this device were explained, and the main components and operating parameters were determined through theoretical analysis. Using fruit-picking roller speed, cleaning belt angle, and fan speed as evaluation indicators, a three-factor three-level field experiment was conducted based on the Box-Behnken central composite design principle. Regression models between loss rate, impurity rate, and significant factors were established, and the optimal working parameters were determined using regression equations. The results showed that when the fruit-picking roller speed was 543.7 r/min, the cleaning belt angle was 50.3°, and the fan speed was 532.4 r/min, the loss rate of sesame seed harvesting was 2.67%, and the impurity rate was 2.49%. The results of field validation experiments indicated that the average loss rate of the combined threshing and cleaning device under the optimal parameter combination was 2.88%, and the average impurity rate was 2.41%, which were consistent with the optimization results of the regression model and fully met the requirements of mechanized sesame seed harvesting production.

“Lunar New Year” by A. Parkau: cultural memory

This article considers the Russian émigré literature in China in the aspect of implementing the principles of intercultural communication and interaction between the cultures of Russia and China. Scholars began to study it in the 1990s, and currently the work of many Russian writers from Harbin and Shanghai remains unexplored. Features of the interaction of national traditions are analyzed in the poem “Lunar New Year” (Chinese New Year) by the poet of the Russian diaspora — A. Parkau, published in the poetic book Unquenchable Fire. Her artistic world still is not in the focus of the scholars. The poem “Lunar New Year,” included in the Bitter Paths cycle, is the artistic description of the Chinese holiday. Its content is determined by Chinese culture, and its artistic form is determined by the Russian poetic tradition. The article traces the connections of the poem with Chinese culture and philosophy, on the one hand, and with the contexts of the Russian poetry of the 19th century, expressed in poetic meters, on the other. The authors of the article examine the compositional and semantic principles of organizing a book of poems and come to the conclusion that the analyzed poem is included simultaneously in several cycles — calendar, reflecting the life of nature, and social, expressing the existential ideas of emigrants, expressed with the motives of loneliness, and fear of death, among others.
