Metastatic urothelial carcinoma (mUC) is considered an incurable malignancy; however, patient outcomes are improving with the adoption of novel treatments. A significant portion of patients with UC have HER2 overexpression measured by immunohistochemistry (IHC) and/or fluorescence in situ hybridization (FISH) or HER2 genomic amplifications and/or mutations detected on next-generation sequencing, making HER2 an attractive therapeutic target. Several clinical trials have assessed the efficacy of HER2-targeted therapies in UC, and trastuzumab deruxtecan has recently been approved as a tumor-agnostic systemic therapy for metastatic solid tumors, including mUC, that are HER2-positive by IHC 3+ expression. Nonetheless, clinical trials of HER2-targeting therapies in mUC have used different assays for the measurement of HER2 positivity, which could affect results. This review summarizes past experiences and delves into the controversies and potential of HER2-targeting therapies, including antibodies, tyrosine kinase inhibitors, and antibody-drug conjugates, in mUC.
A systematic review of metakaolin-based alkali-activated and geopolymer concrete: A step toward green concrete
Authors: Qader Diyar N. , Jamil Ary Shehab , Bahrami Alireza , Ali Mujahid , Arunachalam Krishna Prakash
Published: February 2025

Expanding the world’s infrastructure drives up demand for building materials, particularly ordinary Portland cement (OPC) concrete, whose high carbon dioxide (CO2) emissions have a detrimental effect on the environment. To address this issue, researchers looked into employing alternative supplementary cementitious materials (SCMs), including metakaolin (MK), which is derived from calcined kaolin clay with pozzolanic properties, to partially or completely replace OPC in concrete. This review article examines the MK’s application in alkali-activated materials (AAMs) and OPC-based concrete. By interacting with calcium hydroxide, MK functions as a pozzolanic additive for OPC concrete, enhancing its mechanical qualities and durability. The use of MK as a source material in AAMs, a newly developed class of sustainable binders, is also covered in this article. The effects of different combinations of MK with additional SCMs, including fly ash (FA), ground granulated blast furnace slag (GGBFS), silica fume, and rice husk ash, on the characteristics of alkali-activated concrete both in its fresh and hardened states, are compiled. The majority of the articles considered in this study are from the past decade, while some relevant articles from 2014 and earlier are also taken into account. The results showed that adding MK to concrete in combination with FA or GGBFS has excellent synergistic effects on microstructural development, pozzolanic activity, and strength increases. In particular, the MK–FA mix demonstrated the most encouraging performance gains. Because of its large surface area, the use of nano-MK helped achieve a denser geopolymer structure and improve mechanical properties. The best curing temperatures for MK-based geopolymers to gain strength were found to be between 40 and 80°C for a total of 28 days. The review also pointed out that the compressive strength and geopolymerization process of MK-based geopolymers were enhanced by increasing the mass ratio of Na2SiO3 to NaOH and NaOH concentration. Nevertheless, geopolymerization was hampered by unnecessarily high alkali concentrations. Moreover, the compressive strength was increased by partially replacing MK with TiO2 or GGBFS. The synergistic effects of combining MK with other SCMs to improve concrete performance highlight the potential of MK-based solutions in lowering the environmental footprint of concrete buildings.
Effects of writing topic, first language background, and second language proficiency on ‘V that’ clauses in argumentative writing
Authors: Liu Yingying , Zhuang Jingyuan
Published: February 2025

With the growing use of corpora in second language (L2) research, examining the role of writing topics alongside first language (L1) background and L2 proficiency in shaping L2 usage has become increasingly important. This study contributes to this line of inquiry by using a learner corpus of 1,198 argumentative essays to explore how writing topics, in tandem with L1 background and L2 proficiency, influence the use of ‘V that’ clauses (e.g., I think that it is important…) among English as a Foreign Language (EFL) writers. The findings reveal significant effects of writing topic on the diversity and semantic distribution of ‘V that’, variations across L1 backgrounds, a decrease in frequency with higher L2 proficiency, and interaction effects among the three factors in all aspects of ‘V that’ usage. These findings highlight the importance of considering topic effects alongside L1 background and L2 proficiency in corpus-based L2 research, suggesting both theoretical and methodological implications.

Authors: Campos Rivera Gonzalo
Published: February 2025

El análisis de la solvencia del prestatario a través de modelos de credit scoring se presenta como una obligación legal de las entidades de crédito para la concesión de préstamos. Estas entidades dan cumplimiento a dicha exigencia realizando perfilados de solvencia de sus clientes, lo que supondrá un tratamiento de datos personales sujeto al RGPD. Por ello, la correcta identificación de la finalidad del tratamiento permitirá definir las posibilidades de tratamiento de los datos y los usos secundarios que las entidades de crédito podrán darles. El análisis de la cuestión conduce a definir la finalidad del tratamiento en sentido amplio como la de evaluación de la solvencia para la prevención del sobreendeudamiento y el mantenimiento de la salud del mercado financiero. Ello proyectará sus efectos en los usos ulteriores susceptibles de considerarse compatibles, cuestión que podría permitir a las entidades de crédito aumentar el espectro de tratamientos posibles de estos datos.

Authors: Fahed S. , Asif M.
Published: February 2025

In this paper, we extend the idea of Berinde-Type generalized $\alpha-\beta-\psi$ contractive mappings in the setting of complete extended $S_{b}$-metric spaces providing a significant advancement in fixed-point theory. The findings extend fixed point theory beyond metric spaces to $S_{b}$-metric spaces, offering a broader range of applications in optimization, nonlinear analysis and mathematical modelling. Non-trivial examples of the findings are provided to validate our claims. These examples demonstrate the potential of the proposed mappings for solving real-world phenomena. The work also suggests intriguing future research directions, such as generalizing fixed-point theorems and applying them to disciplines like dynamical systems and integral equations.

Published: February 2025

An approach is proposed for modeling the planning of underground infrastructure inmegacities, combining foresight methodology and cognitive analysis methods. The foresightmethodology enables the development of diverse scenarios with numerical characteristics,which are then used as baseline data for cognitive modelling. An algorithm has been devel-oped to construct a numerically stable cognitive map, where the nodes contain reliable datagenerated during the foresight phase. The application of cognitive impulse modelling facili-tates the creation of underground tunnel development scenarios, accounts for uncertain-ties, analyzes the impact of various threats, selects optimal solutions, and justifies their pri-oritization for implementation.

A tudományos ismeretek fordítása nem csupán filológiai feladat, mert kihat a tudományos kommunikáció, a gondolkodás, s rajtuk keresztül a kultúra, a társadalom és a tudomány alakulására és ‒ a választott fordítási stratégián keresztül ‒ az emberiség episztemológiai diverzitásának fenntarthatóságára is. Ágense a fordító: a tudós, a szakfordító/fordítóügynökség vagy a gép. Tanulmányom rámutat azokra a fordítási stratégiákra, amelyeknek episztemológiai következményei vannak a tudásalkotásra, a tudásrendszerek közötti információátadásra, valamint a különféle tudományos ismeretek megőrzésére. Meghatározom a tudomány fordításához szükséges ún. tudományos szakfordítási makrokompetencia fogalmát és összetevőit, majd bemutatom ennek egyedi, diszciplínaspecifikus és episztemikus elemeit. Az általános és szakfordítási kompetenciákon túl ezek teszik képessé a fordítót arra, hogy episztemológiai szempontból felelős, tudatos döntéseket hozzon, miközben a forrásnyelvi szövegváltozattal funkcionálisan egyenértékű, a célkultúra diszciplináris praxisába illeszkedő célnyelvi szöveget alkot. Zárásul az egynyelvűséggel szemben a tudományos többnyelvűség és az episztemológiai diverzitás megőrzésének jelentősége mellett foglalok állást.

A magyarországi kutatók legtöbbet az MDPI-folyóiratokban publikálnak, amelyekben a díjazottak közül csak kevesen közölnek cikket. Tanácsoljuk, hogy a magyar kutatók a nemzetközi díjazottakéhoz igazítsák publikációs gyakorlatukat, hogy növeljék ismertségüket és esélyeiket a rangos díjak elnyerésére. A kutatás ajánlásokat fogalmaz meg a magyar kutatók publikációs stratégiájára is.
Just-in-Time Access for Databases: Harnessing AI for Smarter, Safer Permissions
Authors:   Manager Software Engineering, Capital One, Cyber, Identity Access Management, Plano, TX, USA, Attaluri Vivekchowdary
Published: February 2025

In the evolving landscape of data security, traditional access control mechanisms often fall short in
addressing dynamic and context-specific requirements. As data breaches become more sophisticated, organizations
require more adaptive and intelligent access control strategies. This paper explores the integration of Artificial
Intelligence (AI) into Just-in-Time (JIT) access control models to enhance database security. By leveraging AI, we aim
to create adaptive, context-aware permission systems that grant access precisely when needed, reducing the attack
surface and mitigating unauthorized access risks.
We begin by analyzing traditional access control methods such as Role-Based Access Control (RBAC), Mandatory
Access Control (MAC), and Discretionary Access Control (DAC), highlighting their limitations in handling real-time
access control scenarios. The paper then explores the benefits of JIT access control, emphasizing how it minimizes
over-privileged accounts and reduces security vulnerabilities. Furthermore, we investigate the role of AI in
cybersecurity, particularly in real-time monitoring, anomaly detection, and decision-making processes for access
control.
To achieve a more intelligent access control framework, we propose an AI-driven JIT access model that incorporates
machine learning algorithms, user behavior analytics, and contextual evaluation to determine access permissions
dynamically. The proposed model is evaluated through simulations and case studies to measure its effectiveness in
preventing unauthorized access, reducing the attack surface, and enhancing overall database security. The results
demonstrate that our AI-driven approach significantly improves access accuracy, minimizes false positives and
negatives, and optimizes response times compared to traditional methods.
Through comprehensive analysis, this research provides a roadmap for organizations looking to implement AIenhanced JIT access control mechanisms. By dynamically granting access based on real-time behavioral and contextual
assessments, organizations can significantly improve database security, reduce administrative overhead, and mitigate
insider threats. Future research directions include further refinement of AI models, integration with multi-factor
authentication mechanisms, and testing across diverse real-world scenarios to enhance security effectiveness.
Influence of quartz replacement by Iraqi porcelanite and silica fume on the properties of porcelain products
Authors:   Faculty of Engineering, Babylon University, Babylon, Iraq, Salman Marwa Marza , Nhabih Hussein Talab ,   Department of Civil Engineering, Faculty of Engineering, Babylon University, Babylon, Iraq
Published: February 2025

In this work, Iraqi porcelanite and silica fume were used as a silica source with replacement of quartz in the manufacture of porcelain products to investigate their influence on properties of these products. The specimens were prepared with composition (50: 30: 20) % as kaolin, silica source and feldspar respectively. Then, they dried at (383 K) temperature for 3 hrs. and sintered at (1473 K) temperature by soaking time for 2hrs. The fracture strength, hardness, apparent porosity, bulk density, linear shrinkage, and XRD, SEM and EDS analyses of the specimens were examined. The test results indicated that replacement of quartz by these sources improves the densification behavior and mechanical strength due to form of more amount from the glassy phase and interlocked crystals from mullite phase within the microstructure. Also, this replacement gives an economic interest for the energy saving and reduction of the material consumption, in addition to produce porcelain products with the best mechanical properties.
Methods and Means of Automated Control of the Asphalt Concrete Mixture Density to Controlling Paver in Process of the Road Surface Construction
Authors:   Siberian Federal University, 79 Svobodny pr., Krasnoyarsk, 660041, Russian Federation, Prokopev A. P. , Bolshakov A. A. ,   Peter the Great St. Petersburg Polytechnic University, Saint Petersburg, 195251, Russian Federation
Published: February 2025

The article presents the results of automation of the density continuous control process during laying and compaction of asphalt concrete mixture based on modern information technologies. The process of compaction of the mixture by the paver, accompanied by a continuous change in its physical, chemical and mechanical properties, requires the introduction of a continuously functioning subsystem for predicting of the value mixture density, based on the analysis of signals and digital processing algorithms, into the structure of the automated control system. Therefore, for the software and hardware support of the mixture monitoring density by using various indicators of the degree of compaction, based on the measurement and analysis of signals from sensors, a system has been proposed that solves the problem using a multi-domain approach.

An Introduction to Infophilia, A Positive Psychology of Information
Authors: Coleman Anita S.
Published: February 2025

The goal of Brenda Dervin’s groundbreaking research was not just to develop the sense-making theory but also to “invent communication alternatives and assess their utility.” One of her practice inventions was the ‘Good News newsletter,’ where she created info-sheets for schools and clinics (Neill, 1992, p. 6). Like Dervin, I’ve sought to create new forms of communication through my work as a library school faculty, grounded in prosocial theorizing and contributing to my profound satisfaction. Appendices 1 – 4 detail a case study of my research to showcase prosocial theorizing but this is a background story. In this paper, I focus on my recent research which began last September. I started a weekly Substack newsletter Infophilia, a positive psychology of information to write about it (2023). The newsletter is one of the primary places where I’m drawing from many disciplines, cultures, languages, and societies, to develop and discuss the infophilia theory and framework, an evolutionary, socio-cultural, positive psychology of information. Three infophiles, lovers of information— my father, my husband, and my doctoral advisor, Linda Smith — first made me aware of the human affinity for information with their distinctive information styles. William James’ “lived hypothesis” encourages researchers to experiment with life’s practical challenges and my infophilia work emerges from just such a spirit of curiosity, observation, and experimentation. First, I offer a personal poem in Tamil. Then, I describe the roots of infophilia in positive psychology and infophilic information styles and how it can be measured in individuals. Then, I close with a ‘truth’ story, some metaphors, and the bold ideas that a theory of infophilia offers for global library and information studies and research, however defined.

Published: February 2025

El presente artículo tiene por objeto ofrecer dos manuscritos inéditos del jesuita Gil de la Mata, los cuales se remontan al primer contacto del cristianismo en el Japón en el siglo XVI e incluyen aportaciones históricas acerca del mártir Damián de Yamaguchi. Estos documentos, traducidos también al portugués por Luís Fróis en su Historia de Japam, narran interesantes anécdotas sobre la vida de este personaje en los años anteriores a su asesinato. Su capacidad de predicar y de convertir a sus compatriotas, incluso su singular y desconocido oficio de exorcista, impactaron a muchos autores que narraron algunos acontecimientos acerca de este hombre tan peculiar. En este ensayo se propone, por tanto, otra visión del hermano Damián, catequista ciego que durante un largo período tuvo que reemplazar a los jesuitas expulsados por mandato del daimio Hideyoshi.

Published: February 2025

La reciente Ley Orgánica de representación paritaria y presencia equilibrada de mujeres y hombres ha modificado el reglamento en el que se regula la relación laboral especial de los deportistas profesionales con motivo de la incorporación a esta última de una serie de derechos relativos a la conciliación de la vida laboral y familiar. Esta reforma, más que necesaria, sirve para imponer de manera legal tanto a las federaciones, a los clubes como a aquellas personas que se dedican profesionalmente a la actividad deportiva que se garanticen tales derechos, pues la mera remisión a las normas laborales con carácter supletorio resultaba insuficiente. De ahí, que el ejercicio de los derechos de conciliación hasta el momento resultase una quimera.

A agricultura familiar é de grande importância para o Brasil, por ser a principal fonte de renda de muitos produtores rurais no País. Ademais, o cultivo de alimentos orgânicos em propriedades familiares aumentou nos últimos anos. Objetivou-se identificar as espécies agrícolas de interesse econômico e as práticas de manejo de pragas e doenças nos cultivos orgânicos em um assentamento de Reforma Agrária no estado de Alagoas. As espécies cultivadas são raízes, hortaliças e frutíferas. Rotação e consorciação de culturas, poda das plantas comprometidas pelo ataque das pragas, SAF’s e aplicação de substâncias naturais de fácil aquisição nas propriedades rurais são práticas de controle de pragas e doenças usadas pelos agricultores. Estas técnicas de manejo de pragas estão de acordo com as exigências do Ministério da Agricultura, Pecuária e Abastecimento para a classificação destes produtores como orgânicos, conforme a Legislação Brasileira que garante a permanência destes no Cadastro Nacional de Produtores Orgânicos.
EFICIÊNCIA DA MISTURA DE FOSFORITA COM COMPOSTO ORGÂNICO PARA ALFACE (Lactuca sativa) NO SUDOESTE DA AMAZÔNIA
Authors: Da Silva Luiz Carlos , Da Costa Francimara Souza
Published: February 2025

O composto de resíduos do açaí é adubo para alface. Mas, aplicados isoladamente não atendem às necessidades nutricionais da cultura. Por isso, enriquecê-lo com fósforo de fontes alternativas pode torná-lo fonte deste e de outros nutrientes. Assim, investigar formas de uso desses resíduos misturados com fósforo é importante para prover nova fonte do nutriente para alface orgânica. Avaliamos neste trabalho a eficiência da mistura de fósforo de fosforita com composto orgânico para alface orgânica em ambiente protegido. Para isso, cinco tratamentos foram testados no solo: 0,0 P e uma dose-teste P aplicada de forma isolada, além desta dose recomendada a partir de 3 níveis da mistura fosforita-composto, com 4 repetições. A mistura de 0,436 dag kg-1 de P proporcionou maior acúmulo de matéria seca e concentração e acumulação de macronutrientes, sendo mais eficiente para a produção da alface orgânica em ambiente protegido.

Published: February 2025

Traçadores de curvas características de módulos fotovoltaicos são uma importante ferramenta para monitoramento e avaliação do desempenho de usinas solares. Entretanto, dimensionar o tempo de aquisição de dados é uma tarefa complexa e um valor inadequado pode resultar em curvas características incompletas ou com sobreamostragem na região de tensão de circuito aberto ($V_{oc}$). O objetivo desta metodologia é o dimensionamento correto do tempo de aquisição dos dados. Assim, um fator de ajuste, calculado através de um ciclo de carga do capacitor, é proposto. Este trabalho apresenta uma metodologia de aquisição de dados com ajuste dinâmico, usando um protótipo de traçador de curvas características de módulos fotovoltaicos baseado em carga capacitiva. Os resultados mostram curvas características com uma distribuição mais uniforme dos pontos amostrados, permitindo maior resolução no ponto de máxima potência ($P_{max}$).

This study evaluated FHAVN patients referred to an outpatient clinic after COVID-19, focusing on the severity of FHAVN related to corticosteroid use, and aimed to connect the drug dosage, and disease grade.
Methods: The study was prospectively designed. Patients diagnosed with FHAVN who received corticosteroids for COVID-19 were included. Data collected included demographic information, medical history, corticosteroid dosage, and magnetic resonance imaging results for radiological grading.
Results: A total of 48 patients were evaluated, with a mean age of 46.13 years. A significant majority (81.3%) of the respondents had bilateral FHAVN. The patients received a mean prednisolone equivalent dose of 1295.16±857.98 mg over approximately 18 days. This study found a significant positive correlation between the severity of FHAVN and the dosage and total corticosteroid treatment time.
Conclusions: The findings indicate that the severity of FHAVN is correlated with corticosteroid use. Although corticosteroids have shown benefits in severe COVID-19 cases, their prolonged and high-dose administration poses risks, including the development of FHAVN.

Background: Black rice a special type of rice species known in multiple ways through its beneficial nutrients and health needs and are in need to be cultivated to its outmost potential. Cultivation of weed suppressible variety along with integrated weed management can be considered for high outcome of yield. Methods: A farm trial during kharif season of 2021 and 2022 was laid out in split plot design (SPD) on the experimental field of School of Agricultural Sciences (SAS), Nagaland University, Nagaland consisting of four integrated weed management in the main plot while sub-plot consisting of four cultivars respectively. Result: Grasses, sedges and broad-leaved weeds with a total of 11 species were identified and recorded dominant. Lowest depletion of nutrients by weed was observed with hand weeding at 15 and 30 DAS with cultivar Chakhao Poireiton and was followed with application of pretilachlor @ 1.0 kg ha-1 (PE) fb HW at 40 DAS. Hand weeding at 15 and 30 DAS along with cultivar Chakhao Poireiton exhibited highest plant height, LAI and biological yield and was closely followed with application of pretilachlor @ 1.0 kg ha-1 (PE) fb HW at 40 DAS with Chakhao Poireiton, while similar results were also observed with the phenological studies. Further, weedy check recorded lowest plant height and LAI. However, plant population showed no significant variation with context to integrated weed management and different cultivars in both the years. Additionally, correlation studies revealed a strong negative correlation between plant height and nutrient depletion by weeds.

Biomass, as an emerging environmental and renewable resource derived from various green sources, is increasingly being recognized for its inherent structural characteristics that are conducive to the production of high-value chemicals. The complicated structure and oxygen-rich nature of biomass and its derivatives necessitate high-value targeted conversion, typically involving liquid-phase hydrogenation or the addition of acidic or basic environments. These processes impose stringent requirements on the efficiency and durability of the catalysts. Recently, the innovation of single atom catalysts (SACs) with individual catalytic sites dispersed on various supports has demonstrated high catalytic efficiency and good selectivity. Owing to their high atomic utilization and cost-efficiency, SACs have emerged as one of the most promising heterogeneous catalysts. This review summarizes current progress on the catalytic conversion of biomass mediated by SACs. Significant emphasis is placed on the unique active sites and reaction mechanisms of SACs in various kinds of catalytic methods (thermocatalysis, electrocatalysis, photocatalysis). In order to facilitate comparison, the various reactions are categorized according to the type of raw material (cellulose, hemicellulose, lignin, etc. ). Especially, the developing strategies for preparing SACs are summarized to better satisfy industrial requirements. Finally, we provide an anticipatory outlook of future developments in this field, focusing on biomass utilization and advanced catalytic systems.

Constructing Physics From Measurements
Authors: Harvey-Tremblay Alexandre
Published: February 2025

We present a reformulation of fundamental physics from an enumeration of independent axioms into the solution of a single optimization problem. Any experiment begins with an initial state preparation, involves some physical operation, and ends with a final measurement. Working from this structure, we maximize the entropy of a final measurement relative to its initial preparation subject to a measurement constraint. Solving this optimization problem for the natural constraint --the most permissive constraint compatible with the problem-- identifies an optimal physical theory. Rather than existing as separate postulates, quantum mechanics, general relativity, and the Standard Model gauge symmetries emerge within a unified theory. Notably, mathematical consistency further restricts valid solutions to 3+1 dimensions only. This reformulation reveals that the apparent complexity of modern physics, with its various forces, symmetries, and dimensional constraints, emerges as the solution to an optimization problem constructed over all realizable experiments in nature.
Determinants of Brain Drain and the Role of Citizenship in Skilled Migration

Published: February 2025

Brain drain represents a critical challenge to global development, reflecting structural inequalities and tensions between mobility and rootedness. This study analyzes the determinants of skilled migration in 178 countries (2006-2022) using a regression model based on panel data, identifying six key variables: uneven economic development, quality of public services, external intervention, voice and accountability, rule of law, and political stability. Governance, particularly political stability and the rule of law, stands out as crucial for retaining talent, while external interventions and economic inequality exacerbate emigration. From a sociological perspective, migrants are active agents who transform transnational networks, challenging traditional notions of citizenship and belonging. Civil society organizations play a central role by facilitating sociocultural inclusion, mediating resettlement processes, and promoting brain circulation as an alternative to retention-focused models. Additionally, the study highlights the cultural and symbolic dimension of migration, revealing the impact of uprooting on communities of origin. Future research should explore how inclusive policies, digital nomadism, and remittances can reduce structural inequalities, strengthen the connection between migrants and their communities, and advance towards a sustainable and equitable mobility model.
Fundamental Equations for Turbulent Motion of an Incompressible Viscous Fluid
Authors: Sun Bo Hua
Published: February 2025

Turbulence, by definition, arises from the interplay between fluid viscosity and velocity gradients. This insight prompted a re-examination of the foundational equations of fluid motion. The analysis reveals that the only arbitrary aspect in formulating these equations lies in the choice of the fluid's constitutive equation. The paper argues that, in turbulent flow, the substantial velocity gradients necessitate retaining second-order terms related to the deformation rate in the constitutive equation, which are often neglected. This retention leads to a more accurate constitutive equation for viscous fluids, enabling the derivation of hydrodynamic equations tailored for turbulent motion, free of adjustable parameters, and offering a refined modification of the Navier-Stokes equations.
Multi-level Conflict-Aware Network for Multi-modal Sentiment Analysis
Authors: Gao Yubo , Wu Haotian , Zhang Lei
Published: February 2025

Multimodal Sentiment Analysis (MSA) aims to recognize human emotions by exploiting textual, acoustic, and visual modalities, and thus how to make full use of the interactions between different modalities is a central challenge of MSA. Interaction contains alignment and conflict aspects. Current works mainly emphasize alignment and the inherent differences between unimodal modalities, neglecting the fact that there are also potential conflicts between bimodal combinations. Additionally, multi-task learning-based conflict modeling methods often rely on the unstable generated labels. To address these challenges, we propose a novel multi-level conflict-aware network (MCAN) for multimodal sentiment analysis, which progressively segregates alignment and conflict constituents from unimodal and bimodal representations, and further exploits the conflict constituents with the conflict modeling branch. In the conflict modeling branch, we conduct discrepancy constraints at both the representation and predicted output levels, avoiding dependence on the generated labels. Experimental results on the CMU-MOSI and CMU-MOSEI datasets demonstrate the effectiveness of the proposed MCAN.
