Cardiovascular disease (CVD) can be determined and quantified using the electrocardiogram (ECG) analysis. Identification of the risk factors associated with ECG abnormalities may advise prevention approaches to decrease CVD burden. In this study we aimed to investigate the association between CVD risk factors and minor and major ECG abnormalities in a general Iranian adult population. This study was conducted in 2010 and covered a population of 9035 males and females aged 35 to 65 years recruiting from the phase I of Mashhad Stroke and Heart Atherosclerotic Disorder (MASHAD) cohort study. The participants were drawn by a stratified cluster random sampling technique. The Bivariate and multinomial logistic regression analysis were conducted considering gender stratification to explore the association of ECG abnormalities with traditional cardiovascular risk factors. There was a significant association between minor and major ECG abnormalities and hypertension (HTN), type 2 diabetes (T2DM), smoking, and physical activity (p < 0.005). There was a significant trend, in both genders, for increasing major abnormalities as the number of CVD risk factors increased. But, only in women, the minor abnormalities increase in frequency as the number of CVD risk factors increased. The results of multinomial logistic regression showed that men with HTN [ARRR = 1.25, 95% CI 0.99, 1.57] and T2DM [ARRR = 1.31, 95% CI 0.99, 1.74] had the highest likelihood to have major abnormalities, although these are not statistically significant. For women, those with HTN had the highest likelihood to have major [ARRR = 1.36, 95% CI 1.13, 1.63] and minor [ARRR = 1.35, 95% CI 1.15, 1.58] abnormalities. Also, women aged > 60 years were more likely to have major [ARRR = 2.01, 95% CI 1.49, 2.74] and minor [ARRR = 1.59, 95% CI 1.20, 2.10] abnormalities compared to women aged < 45 years. Age and HTN were significantly associated with major and minor ECG abnormalities in women, and, on the other hand, HTN and T2DM were associated with major abnormalities in men. Taken together, these findings suggest that healthcare providers should advise preventive approaches to the asymptomatic adults with both major and minor electrocardiographic abnormalities that may predict cardiovascular risk.

Published: May 2024

Smoke detectors face the challenges of increasing accuracy, sensitivity, and high reliability in complex use environments to ensure the timeliness, accuracy, and reliability of very early fire detection. The improvement and innovation of the principle and algorithm for smoke particle concentration detection provide opportunities for improving the performance of the detector. This study represents a new refinement of the smoke concentration detection principle based on capacitive detection of cell structures, and detection signals are processed by a multiscale smoke particle concentration detection algorithm to calculate smoke concentration. Through experiments, it was found that the detector provides effective detection of smoke particle concentrations ranging from 0 to 10% obs/m; moreover, when the detection accuracy is greater than a certain number of parts per million (PPM), the sensitivity of the detector can reach the PPM level; furthermore, the detector can detect smoke particle concentrations higher than the PPM level accuracy even in an environment with a certain concentration of petroliferous and dust particles of different sizes.

Published: May 2024

The Lake Chad basin is one of the most politico-ecologically complex regions in Africa. The rapid global climate change caused by decades of unsustainable resource utilization has not only impaired the ecosystem function but has escalated further conflict with the associated terrorism in the region. This paper reviews the notion of environmental peacebuilding through the introduction of trans-boundary conservation as a mechanism to achieve peace and harmony in the Lake Chad region. The proposed trans-boundary conservation area will restore ecosystem services, conserve biodiversity, improve livelihood, and reduce poverty in the Lake Chad basin. The paper provides justification for the establishment of the “Lake Chad trans-boundary Ramsar site” as an example of how a trans-boundary conservation area could act as a catalyst for improved political cooperation using inter-linkage with other Multilateral Environmental Agreements in the region.

Authors: Khassenova Zhazira , Balykova Akkaiyn , Mukhambetgaliyeva Alima
Published: May 2024

The article examines key aspects of the environmental state of the West Kazakhstan region in the late 1990s to early 2000s. It presents characteristics of the general environmental condition, atmospheric air quality, water quality, and environmental protection measures. An analysis of official data sources indicates that increased hydrocarbon production at the Karachaganak oil and gas condensate field (KOGCF) and other industrial enterprises led to a rise in gross emissions of pollutants into the atmosphere, particularly nitrogen dioxide, carbon monoxide, and hydrogen sulfide. The authors highlight a significant risk of river pollution from heavy industry waste in the region. Moreover, the analysis reveals that despite ample water and mineral resources, the West Kazakhstan region did not effectively utilize them for agricultural purposes. In conclusion, it is evident that the environmental state of the region was negatively impacted by increased pollution of atmospheric air and water resources with toxic metals resulting from industrial activities.

Published: May 2024

Mathematical modeling appears to be a valuable tool for controlling the cooling and storage process of agricultural products. Therefore, mathematical modeling of the balance of heat and mass in refrigeration chambers is relevant. Mathematical modeling of the thermal regime of the thermal regime of a refrigeration chamber with a heat pump and determining temperature changes depending on time. Mathematical modeling is carried out based on the thermal balance of the refrigerating chamber by the method of conservation of mass and energy. It has been established that cooling and long-term storage of agricultural products in refrigeration chambers require a huge amount of electrical energy. At an outside air temperature of 30℃, it takes 30-40 minutes to cool products to the required temperature; for long-term storage, 5.5-6.0 kWh/day of electrical energy is consumed. A combined dryer-refrigerator with a heat pump for storing agricultural products is proposed and a mathematical model of the refrigeration chamber is given, which makes it possible to analyze the temperature regime in the refrigeration chamber.

Authors: Sambuu Anna
Published: May 2024

The article discusses the results of studying the natural vegetation restoration of different-age dumps of the Kaa-Khem coal deposit in the Republic of Tyva (Russia). Flora and vegetation, geographical and ecological spectra, ecological and cenotic groups, plant life forms of reclaimed dumps are analyzed. It was revealed that the basis of the vegetation cover of the dry steppes in the study area is the steppe type of vegetation. The flora of vascular plants is dominated by the Poaceae, Asteraceae and Chenopodiaceae families; The geographical spectrum consists of groups of species with Eurasian and Asian ranges; the ecological spectrum is dominated by xerophytes; weed species dominate at the initial stage of restoration, the number of zonal steppe plants gradually increases, but the proportion of weeds is high; herbaceous polycarpics predominate in the biomorphological structure. Vegetation restoration on coal mine dumps in the steppe zone of Tuva is characterized by a delay in the pioneer stage, significant adventization of communities on 20-50-year-old dumps. Communities of different age dumps are at one of the advanced stages of succession, quite far from the terminal level. The purpose of the study is to study the vegetation cover during self–healing of different-age dumps of the Kaa-Khemsky coal mine.
Modeling the water regime of the Kura cascade of reservoirs in the Republic of Azerbaijan
Authors: Mekhtieva Banovsha , Abdullayeva Maya
Published: May 2024

This study was conducted in connection with the recent increasing attention to saving water resources in Azerbaijan and to studying the condition of the largest cascade of reservoirs on the Kura River. The article highlights some aspects of hydrological modeling of this cascade. Modeling occurs in several stages: an orographic scheme is created, a system of differential equations compiled on the basis of this scheme is solved, and the results are displayed. To carry out the simulation, a program was developed in the MATLAB environment. The program works in 2 modes – design and working. In the design mode, an orographic diagram is created, including the main objects of the cascade (reservoirs, rivers, canals) and their parameters are set (volume, water transfer, geodata about location). The program allows you to edit and add objects. When switching to the operating mode, according to the selected model, a system of differential equations is created corresponding to the current orographic scheme. The number of equations is equal to the number of reservoirs in the cascade. The equations are solved using MATLAB. The solution is carried out sequentially, starting from the first equation of the system. Then the results found are substituted into the 2nd equation. With each subsequent equation its complexity increases. The results are displayed in the form of obtained formulas and in the form of graphs reflecting the state of the cascade. Thus, the developed program has the ability to carry out visual design, and can also be successfully used to model similar reservoir cascades.

Published: May 2024

Plasma chemical aquatermolysis of heavy oil feedstock allows increasing the depth of oil refining and the yield of light hydrocarbons. In the present work, the process of NTP-pyrolysis of a mixture of fuel oil with water (10 wt%) in the liquid phase at 700V was carried out. The introduction of water (10 wt%) into the fuel oil leads to changes in the conversion rate, product composition and energy consumption. Addition of 10 wt% of water to fuel oil increases the conversion rate from 18.6 to 25.9 wt% and reduces energy consumption. The main products are carbon materials, acetylene, ethylene and C3-C6 hydrocarbons.

Authors: Minnivaleev Timur , Minnivaleev Arthur , Gimaeva Lilia , Gabzalilova Alfira
Published: May 2024

In this work, the vulnerability of standard PDC bits was established when conducting wells in difficult mining and geological conditions, in particular, with frequent layering of rocks with different hardness. The use of adaptive TerrAdapt chisels, which automatically change the depth of cutting and the aggressiveness of the chisel, is proposed in Russian deposits with frequently alternating rocks. These bits can be combined with overhead dampers if the dynamic coefficient is in the critical range. This solution will improve the technical and economic performance when drilling wells.

Published: May 2024

This paper examines the low-sulfur gas deposit GKF Uchkyr, which has been preserved for an extended period due to the absence of sulfur removal facilities. The findings regarding the reasons for surpassing or falling behind the actual and projected development indicators are outlined. Additionally, the results of geological and geophysical studies, along with the factors contributing to the insufficient volume of research, are presented. To organize control over the development of a gas field, the correct choice of parameters characterizing the state of the deposit during its development is important. In this case, must be observed conditions that ensure systematic monitoring of changes in selected parameters and assessment of measurement error. These parameters are: reservoir pressure in the gas and aquifer parts of the deposit, gas saturation coefficient of the developed formation, ion-salt composition of the water produced by gas wells. Considering the information above, recommendations are provided to facilitate timely monitoring of changes in technological development indicators and to enhance the efficient extraction of hydrocarbons from the productive horizons of the GKF Uchkyr deposit.

Eimeria tenella is an obligate intracellular parasite which causes great harm to the poultry breeding industry. Protein phosphorylation plays a vital role in host cell–E. tenella interactions. However, no comprehensive phosphoproteomic analyses of host cells at various phases of E. tenella infection have been published. In this study, quantitative phosphoproteomic analysis of chicken embryo DF-1 fibroblasts that were uninfected (UI) or infected with E. tenella for 6 h (PI6, the early invasion phase) or 36 h (PI36, the trophozoite development phase) was conducted. A total of 10,122 phosphopeptides matched to 3,398 host cell phosphoproteins were identified and 13,437 phosphorylation sites were identified. Of these, 491, 1,253, and 275 differentially expressed phosphorylated proteins were identiﬁed in the PI6/UI, PI36/UI, and PI36/PI6 comparisons, respectively. KEGG pathway enrichment analysis showed that E. tenella modulated host cell processes through phosphorylation, including focal adhesion, regulation of the actin cytoskeleton, and FoxO signaling to support its early invasion phase, and modulating adherens junctions and the ErbB signaling pathway to favor its trophozoite development. These results enrich the data on the interaction between E. tenella and host cells and facilitate a better understanding of the molecular mechanisms underlying host–parasite relationships.
L’expérience du temps au cours du suivi psychothérapeutique d’une étudiante universitaire en phase anxio-dépressive
Authors: Voltolini Paião Ariane , Aguirre Antúnez Andrés Eduardo
Published: May 2024

En particulier sous l’influence d’Henri Bergson, Eugène Minkowski a proposé de comprendre chez ses patients une dimension vécue du temps qui fonde l’expérience singulière des personnes. La méthode phénoméno-structurale qu’il a initiée valorise plus largement une approche compréhensive de l’être humain dans son unité intérieure où l’expérience spatio-temporelle joue un rôle décisif. Les relations interpersonnelles et le langage courant y sont utilisés pour saisir l’expérience d’un temps dégradé chez des personnes atteintes de certains troubles psychiques tels la mélancolie et les états dépressifs.

L’objectif de ce travail est d’aborder dans cette perspective les dimensions vécues de l’expérience temporelle d’une jeune femme présentant des symptômes dépressifs et anxieux. Dans la relation avec elle s’éprouve une temporalité accélérée tournée vers un avenir illusoire. Au cours des entretiens cette étudiante part d’un sujet, le fait suivre par un autre puis revient aussitôt en le clarifiant ou le justifiant par rapport au thème précédent presque sans respiration intermédiaire. La thérapeute éprouve le malaise de ne pouvoir se maintenir en phase avec une patiente toujours en avance qui manifeste beaucoup de difficultés à vivre dans le présent sans parvenir à accéder à ses sentiments ni les partager dans sa rencontre avec autrui. À travers le langage, ce présent apparaît sacrifié à un « avenir » ressenti comme étranglé et dépourvu de sens authentique. La compréhension de l’expérience du temps vécu au fil d’une relation à orientation psychothérapeutique confirme ici toute son importance à l’égard d’une psychologie clinique où la voie phénoméno-structurale se montre déterminante pour l’exploration en profondeur de la nature de ces phénomènes spécifiques.
Ouvertures sensibles et mouvements symboligènes dans le travail du contretransfert corporel : rencontre avec Lila

Published: May 2024

C’est au travers de l’analyse d’un cas clinique d’une jeune enfant suivie en thérapie psychomotrice que l’auteur témoigne du travail psychique en profondeur qui se vit dans la relation thérapeutique, et qui s’exprime à travers le corps. Lila, au départ adressée pour d’inquiétantes difficultés évoquant un trouble autistique, impressionne dans un premier temps par sa façon d’être-au-monde. Peu à peu, en passant par une phase symbiotique très forte, Lila commence à se construire en s’appuyant activement sur les ajustements dans l’accordage. L’auteur écoute et travaille son contre-transfert corporel (ensemble des éprouvés, sensoriels et émotionnels vécus dans le lien avec le patient pour être ensuite pensés et retransmis autrement), – et s’appuie sur une présence sensible continue au fil des séances, afin d’initier et de soutenir les processus de symbolisation et de construction identitaire.

A larger percentage of our population is aging healthily and living on to a ripe old age. 60 years of age is taken as cut-off for identifying geriatric population for the purpose of specialized healthcare. The incidence of cancer is increasing and its expected more so in the geriatric population. At present , there are a limited cancer centres where specialized geriatric clinic is being conducted.

Some of the the key unmet needs are — lack of resources and time for dedicated geriatric screening, lack of validated interventions and lack of awareness about the field of geriatric oncology. Some of the proposed solutions are increasing orientation and exposure of trainees and early career oncologists as well as carrying out country specific research to find useful interventions in this field.
Business Equity and Wealth Inequality in Central and Eastern Europe
Authors: Jakurti Edison
Published: May 2024

This paper analyzes the contribution of business equity, housing wealth and the rest of net wealth, to wealth inequality in eight post-socialist countries. Using the third wave of Household Finance and Consumption Survey, we decompose wealth inequality by factor components and use bootstrapping to provide statistical inference. We find that business equity, accounting for over 50% of within-country inequality in most cases, significantly surpasses the contribution of housing wealth. We extend our analysis through a novel simulation approach, employing counterfactual scenarios, to assess variations in between-country inequality. We find that the greatest reduction in the wealth inequality between these countries would occur if business equity were distributed more equally.

Magnetoresistance and magnetic field-induced phase transition in two-dimensional antiferromagnet Fe1/3NbS2
Authors: Liu Han-lei , Luo Zi-yan , Guo Jun-jie , Wang Xi-guang , Nie Yao-zhuang , Xia Qing-lin , Guo Guang-hua
Published: May 2024

We perform systematic studies on the magnetic and magnetotransport properties of Fe1/3NbS2 single crystal. Results show that Fe1/3NbS2 is an antiferromagnet with strong perpendicular magnetocrystalline anisotropy even in the paramagnetic state. The Fe1/3NbS2 nanoplate exhibits exotic magnetotransport characteristics with variation of temperature and magnetic field in the vicinity of Néel temperature. The temperature dependence of resistivity indicates that the magnetic field has a substantial effect on the Néel order of Fe1/3NbS2, and an intermediate phase occurs before the sample enters into the antiferromagnetic state. It is the field- or temperature-induced antiferromagnetic–intermediate phase and intermediate phase–paramagnetic phase transitions that lead to the novel magnetotransport characteristics in the vicinity of Néel temperature. The findings in this work will promote future studies based on two-dimensional antiferromagnetic spintronics.

In a tractable special case where the informed researchers’ theory can identify the true causal mechanism with very few data, we characterize the optimal level of dissemination noise and highlight the relevant trade-offs. Dissemination noise is a tool that statistical agencies currently use to protect privacy. We argue this existing practice can be repurposed to screen

Journalists’ questions during crisis
Authors: Hernández Alfonso
Published: May 2024

During the Covid-19 pandemic, various institutions held press conferences to inform the public about the situation. Journalists engaged in these events to obtain information and to scrutinize the appropriateness of authorities’ measures. Previous research has shown that journalists have become more adversarial towards politicians, but also that health crises make journalists more cooperative with authorities to help manage the situation. However, it remains unknown to what extent journalists retain their deliberative aim in press conferences where crises are addressed, and how their interventions as a whole shape discussions with authorities. A corpus of twenty-one press conferences held by seven institutions was annotated according to the argumentative moves of journalists. Results show that journalists displayed a wide array of argumentative moves, and the findings suggest that journalists incline towards retrieving information during crises, unless the situation gets intertwined with political turmoil.
Revisiting “aberrant” features in Saek
Authors: Pittayaporn Pittayawat
Published: May 2024

This study challenges the notion of Saek as an aberrant member of Tai by proposing that certain features previously considered archaic are, in fact, contact-induced innovations. Specifically, it argues that multiple correspondences involving /j-/ and the alleged split of the Proto-Tai *A1 tone can be traced back to Vietnamese and Lao or Thai influence. Additionally, this paper asserts that Saek is closely related to Fusui, a Northern Tai dialect spoken in southwestern Guangxi. This paper concludes that Saek is a Tai language with some unique retentions and traces of contact with neighboring languages.
Stability of the isotropic conductivity reconstruction using magnetic resonance electrical impedance tomography (MREIT)
Authors: Wang Haiyang , Song Yizhuang
Published: May 2024

Magnetic resonance electrical impedance tomography (MREIT) is a high-resolution imaging modality that aims to reconstruct the objects’ conductivity distributions at low frequency using the measurable z-component of the magnetic flux density obtained from an MRI scanner. Traditional reconstruction algorithms in MREIT use two datum subject to two linearly independent current densities. However, the temporal resolution of such a MREIT image is relatively low. Recently, a single current harmonic Bz
algorithm has been proposed to improve the temporal resolution. Even though a series of reconstruction algorithms have been proposed in the last two decades, the theoretical studies of MREIT are still quite limited. This paper presents the stability theorems for two datum and a single data-based isotropic conductivity reconstruction using MREIT. Using the regularity theory of elliptic partial differential equations, we prove that the only instability in the inverse problem of MREIT comes from taking the second-order derivative of the measured data Bz
, the z-component of the magnetic flux density. To get a stable reconstruction from the noisy Bz
data, we note that the edge structure of

reveals the edge features in the unknown conductivity and provides an edge-preserving denoising approach for the

Optimal sensor placement for leak location in water distribution networks based on graph learning algorithm
Authors: Li Juan , Cai Baoyi
Published: May 2024

The effective monitoring of urban water distribution networks (WDNs) relies heavily on pressure sensor placement. Nevertheless, a WDN may consist of hundreds of nodes, and it is not economically feasible to install sensors at each node. Therefore, how to identify an optimal location for sensor placement becomes a crucial issue. We use graph signal processing to analyze the pressure signals and introduce a framework for optimal sensor placement specifically designed for pressure signals. To address the limitation that pressure signals cannot be sampled directly, we propose a method to convert the signal into a band-limited signal that meets the requirements. Central to the method is learning a graph Fourier operator, and the effectiveness of the proposed method is proved theoretically. The graph Fourier operator enables the pressure data to become a smooth graph signal with variations in its topology. In addition, we design a graph filter based on the energy of the signal and obtain a band-limited signal that meets the requirements. To ensure the selection of representative nodes, we use a noise-robust graph sampling method to obtain the sensor node. Our method is further evaluated using the pressure data from Anytown versus Net3, showing strong performance in leak identification and signal reconstruction capabilities.
A feature separation simulation-assisted transfer framework for rotating machinery fault intelligent diagnosis

High-quality labeled data are crucial prerequisites for ensuring the effectiveness of fault diagnosis methods based on deep learning technology. However, in practical scenarios, providing abundant training data with accurate labels for these approaches is unfeasible owing to the constraints imposed by the operating and working conditions. To tackle this realistic challenge, we propose an innovative feature separation simulation-assisted transfer framework (FSSATF) for the fault diagnosis of rotating machinery. The primary concept of FSSATF is to leverage dynamic simulation-assisted data as a surrogate for the labeled data of actual equipment and integrate the feature separation network to explicitly extract domain-independent and fault-discriminative features from the simulated and actual domains, facilitating knowledge transfer and enhancing fault diagnosis capabilities. Specifically, we design a feature separation network consisting of two feature extractors. The special feature extractor is trained with the proposed target domain classification loss to explicitly separate the noisy features from the actual data. Moreover, our proposed domain adaptive loss function effectively narrows the distribution discrepancy between the simulated and actual data, promoting the shared feature extractor to capture domain-invariant and fault-discriminative features. Additionally, clustering learning is embedded into FSSATF to minimize the distance between samples of the same category, strengthening the model’s capabilities for feature extraction, and improving its performance in real machinery fault diagnosis. Artificially damaged and run-to-failure datasets were employed to validate the effectiveness and superiority of FSSATF. The comparative analysis results demonstrate that the fault diagnosis performance surpasses those of other advanced transfer learning fault diagnosis methods.

Rod-type metal corrosion probes based on electromechanical impedance (EMI) technique can quantitatively assess the amount of corrosion, which have a promising application in pipeline corrosion monitoring and have received much more attention. In the field of structural health monitoring, the EMI technique based on series and parallel connections has been widely studied and is very promising, but it is yet to be used in the probe design. In this work, a kind of novel metal corrosion probe with two piezoelectric elements in series and parallel connections was proposed, and its performance was investigated comprehensively by combining theoretical analysis with experiment research. Theoretical models of the proposed probe in the longitudinal vibration mode for both series and parallel connections were established, and verified by the experimental results. Influences of the thicknesses of piezoelectric layer and ceramic layer on the probe performance were analyzed. Artificial quantitative corrosion tests and accelerated corrosion tests were designed to evaluate the quantitative corrosion monitoring capacity. Temperature sensitivity tests were conducted to study the temperature dependence. The wireless impedance measurement was performed to confirm the online monitoring ability. Comparisons for the probe performance between the series and parallel connections were also presented. This work provided a comprehensive understanding for this kind of novel probe, which is beneficial to develop low-cost, high-precision, high-stability pipeline corrosion real-time monitoring technology.

Published: May 2024

With the development of space exploration activities, the proliferation of non-cooperative targets in space, such as defunct satellites and space debris, has made the development of efficient and reliable non-cooperative target capture technologies in space a priority for space exploration. In this paper, a flexible gripper inspired by the dermo-muscular sac found in flatworms is presented to address the challenges of non-cooperative target capture in the vacuum environment of space. The gripper design leverages magnetorheological fluid and a magnetic field to enable adjustable stiffness, facilitating the effective grasping of delicate target objects while ensuring a stable connection post-capture. Extensive tests demonstrate the strong potential of the gripper for space applications, showcasing its ability to adjust pre-grip contact force and increase gripping force by adjusting indentation depth. The simplicity of the design contributes to ease of manufacturing, making it a promising tool for future space missions.

Published: May 2024

The performance and behavior of origami-inspired mechanical metamaterials are closely related to their structural design and the joints sub equivalent to the crease, in addition to material selection. Current research on square-twist origami focused on the unidirectional formation between its stable states. However, the complete process of squeezing-folding and stretching-unfolding as well as the mechanical behavior under tensile loading have not been thoroughly studied. In this study, square-twist origami mechanical metamaterials (STOMMs) with soft joints are proposed and investigated. The complete process of typical STOMMs from a flat state to folded stable state by extrusion folding and then returning to a flat state by stretch unfolding is explored using the finite element method. The strain energy and deformation characteristics of STOMMs are revealed at eight special stages during the folding, stable state, and unfolding processes. Additionally, the influence of geometric parameters on strain energy, deformation, and tensile behavior is also investigated. Finally, inspired by origami chirality, combinatorial mechanical metamaterials with self-locking/non-self-locking behavior are proposed and validated for their tensile and self-locking behavior. The studies could provide new content for origami-inspired soft joint mechanical metamaterials in terms of self-locking and load-bearing.
Physics-informed deep operator network for predicting martensite evolution in superelastic shape memory alloys through cyclic tensile tests
Authors: Lenzen Niklas , Altay Okyay
Published: May 2024

Superelastic shape memory alloy (SMA) wires and rods possess unique deformation and energy dissipation capabilities. For the assessment of their stress response, commonly cyclic tensile tests are conducted. An important but subtle parameter in this procedure is the martensite evolution. In scenarios where conducting thermal experiments is impractical, inverse modeling from cyclic tests serves as a viable alternative. However, employing constitutive models in this process presents distinct challenges, such as parameter identification and calibration, or numerical stability issues. To address these challenges, this paper proposes a data-driven method based on a physics-informed deep operator network (DeepONet) to estimate the martensite evolution. Constraint with a stress equation, the network requires only strain–stress data for training and provides stress responses in addition to the martensite evolution. From the training data, the network learns to consider the effects included in the response. The DeepONet can be coupled with experiments to provide online estimates from noisy sensor-based strain inputs, while remaining numerically stable. Moreover, this approach avoids the need for separate parameter identification or calibration. This paper details this method and evaluates its performance through experiments conducted on superelastic SMA wires. Furthermore, as an alternative approach, training using a constitutive model is provided.
