Improved modified gradient-based iterative algorithm and its relaxed version for the complex conjugate and transpose Sylvester matrix equations
Authors: Huang Zhengge , Cui Jingjing 
Published: November 2024

Abstract
In this article, we present two new algorithms referred to as the improved modified gradient-based iterative (IMGI) algorithm and its relaxed version (IMRGI) for solving the complex conjugate and transpose (CCT) Sylvester matrix equations, which often arise from control theory, system theory, and so forth. Compared with the gradient-based iterative (GI) (A.-G. Wu, L.-L. Lv, and G.-R. Duan, Iterative algorithms for solving a class of complex conjugate and transpose matrix equations, Appl. Math. Comput. 217 (2011), 8343–8353) and the relaxed GI (RGI) (W.-L. Wang, C.-Q. Song, and S.-P. Ji, Iterative solution to a class of complex matrix equations and its application in time-varying linear system, J. Appl. Math. Comput. 67 (2021), 317–341) algorithms, the proposed ones can make full use of the latest information and need less computations, which leads to higher computational efficiency. With the real representation of a complex matrix as a tool, we establish sufficient and necessary conditions for the convergence of the IMGI and the IMRGI algorithms. Finally, some numerical examples are given to illustrate the effectiveness and advantages of the proposed algorithms.
On the Reform of Fiscal Rules in the European Union: What Has Been Achieved, and How Did We Get Here?
Authors: Schnellenbach Jan 
Published: November 2024

Abstract
In April 2024, the European Union has reformed its set of fiscal rules, aimed at securing sustainable public finances in its member countries. In this paper, we discuss the pathway towards reform and highlight the main characteristics of the reformed set of rules. It is argued that, relative to the original proposals by the Commission, the rules have improved. However, the numerical safeguards may be circumvented to some extent. In sum, there remains plenty of discretionary leeway for a conflict-averse Commission to appease non-compliant member countries.
On the Funding Chances of Political Theorizing
Authors: Rosales José María 
Published: November 2024

Abstract
This article explores causes and consequences of the declining funding chances of political theorizing with the aim of advancing measures to offset them. Major national and international research programmes growingly present challenges that require problem-solving strategies. Applied research disciplines are better fitted to tackle them than basic research disciplines to which political theorizing belongs. Drawing on the enlightening contribution of theory to political research and politics, it argues that the knowledge it produces can be shared across disciplinary boundaries if its scientific reliability is secured. With that aim, the article submits two practical suggestions: enriching normative accounts of politics with research historically and institutionally informed, and streamlining its enquiring capacity by exploring standard, modular and integrated interdisciplinary approaches.
Visualizing identity: multimodal and multilingual practices in international student organizations’ on-campus artifacts
Authors: Marino Francesca , Mu Yuxuan 
Published: November 2024

Abstract
Contributing to previous research on schoolscape, this study explores artifacts crafted by international student organizations (i.e., flyers and roll-up banners) across a U.S. university campus. Specifically, drawing on elements from geosemiotics (i.e., visual semiotics, place semiotics, and interaction order), the authors examined (1) how the producers convey their identities through both multilingual and multimodal practices, and (2) how the artifacts interact with the surrounding space. Considering the ephemeral nature of the artifacts under scrutiny, pictures of the actual artifacts were collected over a two-month period in 2024. The findings show that the sign makers constructed their identities through varied semiotic resources, including text, images (e.g., national flags, natural elements, historical landmarks), typography (e.g., typographic mimicry), colors indexing ethnocultural and/or national identities or university affiliation, code preferences, and linguistic choices creating multiple interaction orders. Regarding the emplacement of the artifacts, different patterns emerged, including a preference for authorized spaces over those associated with transgressive semiotics, and, more generally, a shift towards digital spaces for organizational promotion.

Bifurcation and chaos: Unraveling soliton solutions in a couple fractional-order nonlinear evolution equation
Authors: Riaz Muhammad Bilal , Jhangeer Adil , Martinovic Jan , Kazmi Syeda Sarwat 
Published: November 2024

Abstract
Shallow water waves represent a significant and extensively employed wave type in coastal regions. The unconventional bidirectional transmission of extended waves across shallow water is elucidated through nonlinear fractional partial differential equations, specifically the space–time fractional-coupled Whitham–Broer–Kaup equation. The application of two distinct analytical methods, namely, the generalized logistic equation approach and unified approach, is employed to construct various solutions such as bright solitons, singular solitary waves, kink solitons, and dark solitons for the proposed equation. The physical behavior of calculated results is graphically represented through density, two- and three-dimensional plots. The obtained solutions could have significant implications across a range of fields including plasma physics, biology, quantum computing, fluid dynamics, optics, communication technology, hydrodynamics, environmental sciences, and ocean engineering. Furthermore, the qualitative assessment of the unperturbed planar system is conducted through the utilization of bifurcation theory. Subsequently, the model undergoes the introduction of an outward force with the aim of inducing disruption, resulting in the emergence of a perturbed dynamical system. The detection of chaotic trajectory in the perturbed system is accomplished through the utilization of a variety of tools designed for chaos detection. The execution of the Runge–Kutta method is employed to assess the sensitivity of the examined model. The results obtained serve to underscore the effectiveness and applicability of the proposed methodologies for the assessment of soliton structures within a broad spectrum of nonlinear models.
Unlocking potential: the role of chemometric modeling in pulp and paper manufacturing

Published: November 2024

Abstract
The review focuses on application of chemometric modeling in raw material characterization and quantification of parameter in various steps of pulp and papermaking processes. These models are built by supervised or unsupervised machine-learning techniques. Chemometric models are predominantly developed with data from spectroscopic instruments like, Ultraviolet spectrophotometer (UV), Near Infrared spectrophotometer (NIR), Fourier Transform Infrared Spectrometer (FTIR), Raman Spectrometer etc. These spectroscopic data are large in size which are reduced by applying different dimension reduction techniques. Moreover, these data contain instrumental noise in most of the cases, and they are de-noised or smoothed by several preprocessing techniques for developing better performing models. Among the popular calibration techniques for classification, Soft Independent Modeling for Classification Algorithm (SIMCA), Discrimination Analysis (DA) are mentionable. Multiple Linear Regression (MLR), Principal Component Regression (PCR), Partial Least Square Regression (PLSR), Artificial Neural Network (ANN), Support Vector Machine (SVM) etc., are used for quantification of different physical, morphological and chemical properties of wood, pulp and paper properties. Based on chemometric models, sensors for online measurements of different parameters in pulping and papermaking processes are being developed in recent years. Through this review, better performing multivariate analysis based chemometric modeling techniques have been identified for determining different parameters by comparing the existing ones which could be used in different processes in pulp and papermaking industries.
Chinas Fähigkeiten im Bereich der Unterwasser-Seekriegsführung: Technologische Aspekte
Authors: Kirchberger Sarah 
Published: November 2024

Kurzfassung
Die Flottenrüstung der Volksrepublik Chinas schreitet mit enormer Dynamik voran. Chinas Marine verfügt bereits heute über mehr Schiffe als die US Navy, und auch die Kapazität der chinesischen Marineschiffbau-Infrastruktur übertrifft diejenige der USA. Noch gibt es einen qualitativen Vorsprung der amerikanischen Seestreitkräfte gegenüber China, aber der Wille ist eindeutig zu erkennen, den Vereinigten Staaten den Rang als wichtigste Seemacht abzulaufen.
Das technologische Gefälle zwischen China und den USA war in der Vergangenheit insbesondere im Bereich der Unterwasser-Seekriegsführung immens, wird aber aufgrund zielgerichteter Anstrengungen der chinesischen Seite stetig kleiner. Treiber dieser Bemühungen ist die in China wahrgenommene militärstrategische Notwendigkeit, die für U-Boot-Operationen bestehenden geographischen Nachteile Chinas auszugleichen.
Der Beitrag befasst sich vertieft mit dem aktuell erreichten technologischen Entwicklungsstand von Chinas Unterwasser-Seekriegsführung. Er vermittelt einen knappen Überblick über technologische Engpässe und Durchbrüche, industrielle Kapazitäten sowie Forschung und Entwicklung (F&E) in für Unterwasser-Seekriegsführung relevanten Feldern. Eine Schlüsselfrage für die weitere Entwicklung wird das das Potenzial für eine vertiefte Zusammenarbeit Chinas mit Russland sein.

Abstract
The performance seeking control (PSC) method is aimed at improving the performance of aircraft engine without changing hardware devices. However, the complexity of the system makes it difficult to achieve its application in engineering. Thus, the key issues in PSC of turbofan engine are studied based on global sensitivity analysis, and the improvements are made to the optimization system according to the analysis. Firstly, the principle of PSC is analyzed based on traditional frameworks. And an improved linear programming method based on task scheduling is proposed to reduce the time consumption within a single closed-loop simulation. The impact of the estimation model accuracy on optimization results is studied adopting a sensitivity analysis method based on Monte Carlo sampling to address the optimization lose efficacy. Finally, the hardware-in-the-loop simulation is carried out utilizing model-based design method in a certain type of turbofan engine electronic controller.
Outlining the impact of electro-osmotic force and mixed convection flow of EMHD nanofluid flow on the stretched cylinder: a computational layout
Authors: Sutradhar Bikash , Das Kalidas , Kundu Prabir Kumar 
Published: November 2024

Abstract
This research has focused on studying the electro-magneto-hydrodynamic (EMHD) nanofluid flow over a stretched cylinder in the presence of electro-osmotic force and mixed convection. This inquiry shows a novel approach through the use of thermophoresis and Brownian motion and nanofluid is comprised of water and copper nanoparticles. Similarity transformations simplified the mathematical model and produced nonlinear ordinary differential equations with suitable boundary conditions, which the MAPLE-21 software numerically solved using the RK-4 shooting criteria. Tables and graphs have been used to illustrate the impact of the key flow factors on Electric potential profiles, velocity profiles, temperature outlines, and concentration distribution. Following the physical deliveries, we have calculated the Sherwood number, Nusselt number, and skin friction. The electro-osmotic parameter diminishes the electric potential profiles and a dual effect occurs for the curvature parameter. The Nusselt number declined by 5.91 % for the electro-osmotic parameter but the Sherwood number enhanced by 30.7 % at a rate. The practical applications of this model shed light on thermal management in electronics and nuclear reactors, plasma physics, various chemical processes, filtration, separation, and fuel cells, as well as the manipulation of biological fluids in lubrication or medical devices.

Este artigo visa a contribuir para a problematização dos impactos de grandes projetos urbanos e de infraestrutura em territórios interioranos fronteiriços, pautadas em uma lógica de cidademercadoria. Distantes das estruturas tradicionais de construção de conhecimento, esses territórios acabam sendo mais vulneráveis a essas reestruturações de grande vulto pela incompreensão dadimensão de seus efeitos ao longo do tempo e à forma como afetam diferentemente os vários segmentos da população. Com esse propósito, à luz do trabalho de estudiosas e estudiosos do campo do planejamento urbano e de pesquisas sobre a Região Trinacional, empreendeu-se uma análise reflexiva de alguns dos grandes planos e projetos em curso nesse território, destacando tendências que atendem aos interesses do capital. Como resposta a esse alinhamento e à necessidade de reparação dos territórios interioranos fronteiriços afetados por esses empreendimentos, as instituições de ensino público, os trabalhos de pesquisa acadêmica e os espaços de educação popular, por adotarem uma abordagem crítica, oferecem contribuições valiosas para pautar o planejamento territorial insurgente, comprometido com a justiça social e ambiental. Os resultados da análise ora apresentada indicam que, sem o devido conhecimento dos interesses envolvidos nesses planos e projetos sob diferentes perspectivas e de quais podem ser os seus efeitos para as comunidades diversas que compõem as cidades interioranas fronteiriças, favorece-se a invisibilidade das ações de incremento da marginalização socioeconômica, do sofrimento ambiental e da ampliação das desigualdades sociais.

Published: November 2024

Indonesia is one of the countries in the world with the most cases of animal violence. The violence ironically also occurs in pets that should receive protection and good care by their owners. In addition to violence, pets are even abandoned by their owners, while it is known that the Indonesian ius constitutum requires animal owners, including pets, to take good care of their animals until they die naturally. This study wants to examine how Indonesian law regulates obligations for animal owners towards their pets, legal protection of pets from acts of violence and neglect committed by owners, and to prevent similar acts from being repeated because apart from these acts violate the applicable legal rules, not in accordance with the dignity and dignity of the Indonesian nation as a civilized nation, it also has the potential to cause an impact/disturbance to order, peace, and public health and the surrounding environment. The research method used is normative juridical with the nature of qualitative analysis using primary legal materials, namely Law Number 41 of 2014 concerning Livestock and Animal Health, Government Regulation Number 95 of 2012 concerning Veterinary Public Health and Animal Welfare and the Criminal Code (KUHP); secondary legal materials; and tertiary legal materials. The results of this study state that acts of violence and abandonment of pets by owners are included in the category of criminal acts, namely crimes and perpetrators can be subject to criminal sanctions.

As an archipelagic country, Indonesia is surrounded by water. Hence, Indonesia is blessed with abundant resources from the sea. However, this brings a series of threats to Indonesia. Amongst them is the issue of overfishing. The country then is committed to fighting the issue through the blue economy approach. The approach is believed to bring not only economic benefits, but also ecological sustainability and security. This research is trying to find how the approach is implemented. The research employs a qualitative approach and a descriptive method. Secondary data is gathered from literature studies and online research. The results show that Indonesia has created a blue economy road map that targets the year 2045 to tackle the overfishing problem. The road map is used to optimize the potential of the sea as well as to overcome environmental problems and this is done through the establishment of marine protected areas. The blue economy road map is concrete evidence of Indonesia’s governments to preserving the sea and keeping the future generation intact.Bahasa Indonesia Abstract: Sebagai negara kepulauan, Indonesia memiliki wilayah laut yang cukup luas dan mengelilingi kepulauannya. Oleh karenanya, potensi laut yang dimiliki oleh Indonesia juga cukup besar. Namun, di balik besarnya potensi laut Indonesia terdapat ancaman yang dihadapi oleh Indonesia. Salah satunya adalah masalah penangkapan ikan yang berlebih (overfishing). Untuk menghadapi masalah tersebut, Indonesia memperkenalkan strategi yang menggunakan konsep ekonomi biru (blue economy) untuk mengatasi masalah overfishing yang dinilai dapat meningkatkan keuntungan tanpa mengorbankan keberlanjutan dan keamanan ekologis. Penelitian ini menggunakan desain penelitian kualitatif, dengan metode deskriptif. Data yang digunakan merupakan data sekunder yang diperoleh dari studi kepustakaan dan penelusuran daring. Hasil penelitian memperlihatkan bahwa Indonesia telah membuat sebuah peta jalan (road map) ekonomi biru dengan target tahun 2045 untuk menghadapi masalah di kelautan terutama overfishing. Peta jalan tersebut untuk mengoptimalkan potensi kelautan yang ada di Indonesia dan mengatasi berbagai masalah dan juga menjaga lingkungan hidup laut lewat pembentukan Kawasan Konservasi Perairan (KKL). Penggunaan ekonomi biru dalam peta jalan yang dibuat oleh Indonesia ini adalah bentuk nyata upaya pemerintah Indonesia untuk mengembangkan potensi sumber daya laut yang dimiliki oleh Indonesia yang didasari pada prinsip berkelanjutan agar dapat dimanfaatkan secara terus menerus tanpa mengorbankan keuntungan di masa depan.
