The Life and Non-Life Insurance Market in the European Union
Authors: Witkowska Justyna
Published: July 2024

The article discussed on the situation of the life and non-life insurance market in the European Union as seen at the end of 2022. The market analysis was based on data derived from the European Insurance and Occupational Pensions Authority (EIOPA) and the Organization for Economic Cooperation and Development (OECD) and included such factors as the number of insurers, the division into life insurance and non-life insurance, and the key market indicators (written premium, density and penetration rates, and concentration index).
The collected data shows the life and non-life insurance market in 27 European Union Member States. The largest number of insurers is in the French, German and Luxembourg markets, the smallest in the Slovak, Estonian, Lithuanian and Latvian markets. It was noted that the more insurers sell insurance in a country, the lower the concentration ratio. Germany and France had the largest share of the global business insurance market in 2022 from EU countries. Overall, EU residents in 2022 spent more on life insurance (€652.2 billion) compared to non-life insurance (€495.2 billion). Residents of EU countries spend most of their life insurance money on index-linked and unit-linked insurance and insurance with profit participation. The largest share of EU residents’ non-life insurance spending is in: Fire and other damage to property insurance, Motor vehicle liability insurance and Other motor insurance.
Just as these countries differ significantly in economic terms, they also do so from the life and non-life insurance market standpoint.

Published: July 2024

Prinsip kebaruan desain industri merupakan unsur yang fundamental dikarenakan menjadi penentu batasan dari adanya ekslusifitas suatu ide yang bernilai estetika. Namun sayangnya, unsur fundamental tersebut tidak diatur secara eksplisit dalam regulasi di Indonesia sehingga hak moral dan ekonomi bagi pengembang desain industri tidak dapat terlindungi dengan baik. Ketidakomperhensifan tersebut berakibat pada inkonsistensi hakim dalam mempertimbangkan dan memutuskan perkara. Penelitian ini bertujuan mengkaji problematika parameter kebaruan dan tingkatan peniruan dalam regulasi desain industri di Indonesia serta implikasinya terhadap pertimbangan hakim di pengadilan. Adapun jenis penelitian ini menggunakan yuridis-normatif dengan pendekatan peraturan perundang-undangan (statute approach), pendekatan konseptual (conceptual approach), dan pendekatan kasus (case approach). Hasil penelitian ini menemukan bahwa ketidakomperhensifan regulasi terkait parameter kebaruan dan sengketa desain industri menimbulkan disparitas putusan hakim di beberapa pengadilan tingkat pertama hingga kasasi. Oleh karena itu, pencantuman parameter kebaruan maupun tingkatan peniruan berguna menjamin kepastian hukum bagi hakim maupun pemilik hak desain industri sehingga berimplikasi terhadap perkembangan komersialisasi dan nilai ekonomi di Indonesia.
Materialistic dialectics as an epistemological basis of a realistic approach to understanding and cognition of truth in various spheres of cognition,
Including in criminal proceedings
Authors: Melnik Valery V.
Published: July 2024

In the article, using the methodology of system analysis, system-functional, system-structural and system-component aspects of the system approach, as well as the method of expert assessments of authoritative specialists professing a realistic approach to understanding and cognition of truth, materialistic dialectics is considered as a composite This part of the realistic theory of knowledge, the epistemological basis of a realistic approach to understanding and knowing the truth in various spheres of cognition, including in criminal proceedings. It is substantiated that one of the reasons for the unproductiveness of the endless discussion between supporters and opponents of the concept of objective truth in the Russian criminal process is that some modern participants in this discussion from both sides in their understanding of dialectical materialism as the epistemological basis of the realistic approach to understanding and knowing the truth stopped at the level of Soviet official philosophy, not taking into account that dialectical materialism is productively developing through philosophical comprehension within the framework of complex and systematic approaches of the achievements of various branches of the natural sciences and humanities covered by the concept of “cognitive sciences”, which contributes to a deeper understanding of the foundations, system-forming factors of the realistic approach to understanding and cognition of truth.

Published: July 2024

The authors of the article, based on a comparative legal analysis of the system of sources of legal regulation of financing of forensic institutions, as well as domestic scientific literature, propose to “transfer: the signs of the system to the concept of a mechanism. Within the framework of the system analysis carried out, the authors of the article proceed from the definition of the system of financial and legal mechanisms for ensuring forensic expert activity as an object of public administration, which is a legal relationship regulated by the norms of law to achieve the set goals and objectives, the use of methods, tools and rules having monetary, organizational, accounting and control content. The article substantiates the need for an integrative approach to the definition of a system of financial and legal mechanisms for ensuring judicial expert activity as a single system subject to legal regulation. The authors propose to define the mechanism of financial support for the activities of a forensic expert institution/organization as a system of education from the norms and institutions of national law contained not only in regulatory legal acts relating to various branches of legislation, but also local acts of state and non-state institutions and organizations; legal and technical documents, among which should be mentioned instructional letters, regulations, methodological recommendations, technical standards, GOST standards, etc., as well as contracts of normative content that ensure international cooperation on forensic activities.

Non-drude-like behavior of the photoinduced dielectric permittivity of GaAs and Si in the gigahertz range frequencies
Authors: Butylkin V. S. , Kraftmakher G. A. , Fisher P. S.
Published: July 2024

A non-drude-like behavior of the real part of the photoinduced permittivity ReåP of GaAs and Si samples in the gigahertz range was detected by direct resonator measurements under conditions of fiber-optic irradiation at a wavelength of ë = 0.97 microns with power changes P in the range of 0÷1 W. It is shown that, in accordance with the hypothesis of the exciton mechanism of the photoinduced microwave dielectric permittivity, ReåP increases with increasing P (approaching saturation above P = 200 mW) instead of decreasing within the framework of free charge carriers by Drude. The generality of the behavior of the real parts of the photoinduced permittivity observed in semiconductors of different types (straight-band GaAs and non-straight-band Si) in different electrodynamic systems (waveguides, resonators, metastructures) testifying to the universality of the exciton mechanism is demonstrated. Optically controlled metastructures in the GHz band containing resonant electrically conductive elements loaded with GaAs and Si samples are proposed for the first time: a metastructure based on linear dipoles and a half-wave electric dipole based on a multi-pass spiral. Gigahertz responses of metastructures and the transformation of responses associated with changes in the dielectric permittivity of Si and GaAs during photoexcitation were measured for the first time. Based on the hypothesis put forward about the effect of excitons on photoexcitation, the observed saturation effect of gigahertz photoinduced permittivity is discussed.

Published: July 2024

Perlite is one of the main structural constituents of carbon and low-alloy steels. In it, between the bcc ferritic and orthoboric cementite phases of Fe3C, the orientational relation (OR) of Bagaryatskii, Isaichev, and Pitch can be observed. The first two, which are close to each other and are not always, repeated in the experiment, predominate in low-temperature pearlite, which has the highest strength. In this study, the simulation "from first principles" by the DFT method in the WIEN2k software package of the structure and energy of coherent α-Fe/Fe3C interfaces was carried out. The supercells were subjected to structural and volume optimization. Calculations of the surface energy of the interphase boundaries gave the values of 0.383 J/m2 for the Bagaryatskii OR and 0.594 J/m2 for the Isaichev OR. This agrees well with the existing experimental values and the results of other molecular dynamics and first-principles calculations. The difference in surface energy can play a significant role for low-temperature pearlite with a small thickness of ferrite and cementite plates and a large area of interfacial boundaries per unit volume.

The influence of proton irradiation with a dose of 50 Mrad (Si) on the optical properties and defect formation in crystals of the gadolinium-aluminum-gallium garnet with the substitution of aluminumand gallium in the cationic sublattice: Gd3Al2Ga3O12 (Al: Ga = 2:3) and Gd3Al3Ga2O12 (Al: Ga = 3:2) was studied. After proton irradiation, color of crystals changes: an additional absorption band appears in the transmittance of each crystal in the wavelength range 400–500 nm. This occures due to the formation of induced structural defects as color centers. The refractive indices n(λ) were determined by the Brewster spectrophotometric method and practically did not change for Al:Ga = 2:3 crystals, but significantly increased for Al:Ga = 3:2. There is a noticeable increase in the attenuation of the light in spectral dependences, which also indicates the formation of additional structural defects.
Mechanisms of formation and accumulation of misorientations in deformable metals and alloys
Authors: Cherepanov D. N. , Solov’eva Yu. V. , Starenchenko V. A.
Published: July 2024

The formation of misoriented substructures in plastically deformable metal materials has been theoretically studied. Expressions are obtained for the intensity of accumulation of low-angle and high-angle misorientation boundaries. Within the framework of a mathematical model of shear plastic deformation and hardening, numerical calculations of the dependences of the average characteristics of a defective medium on the degree of deformation under conditions of uniaxial compression with a constant strain rate at room temperature are performed. It is shown that the intensity of generation of low-angle tilt walls depends significantly on the scenario of changes in the density of jogs on the screw segments of dislocation loops emitted by dislocation sources. The main mechanism for the formation of low-angle walls is the rearrangement of clusters of edge segments of dislocation loops into tilt dislocation walls under the influence of flows of interstitial atoms generated by moving screw segments. It is assumed that low-angle walls merge into one until the total misorientation angle of the merged walls reaches a critical value of about 10°, after which the distance between dislocations in the wall decreases to the corresponding critical value and further penetration of individual dislocations into the wall becomes impossible. The expression for the intensity of the formation of high-angle boundaries was obtained as a consequence of the continuation of the work of dislocation sources and the formation of clusters of low-angle walls, the total energy of which is higher than the energy of an equilibrium high-angle boundary at the same misorientation.
Interaction of Titanium Atoms with the Surface of Perfect and Defective Carbon Nanotubes

Published: July 2024

The dispersion of metal atoms over the surface of 1D and 2D carbon systems is the most affordable way to control their properties, which are attractive for many applications in electronics, power engineering, and catalysis. In this work, the features of the interaction of titanium atoms with the surface of carbon nanotubes, caused by various structural defects on these surfaces, were studied by first-principles computer simulation based on the density functional theory. Nanotubes (7, 7) and (11, 0) with similar diameters (≈1 nm) but different types of conductivity, metallic and semiconductor, respectively, were chosen for the study. Three types of defects were studied: a single vacancy, a double vacancy, and a topological defect. Two possible orientations of each type of defect relative to the tube axis were considered. We mainly used the basis of atomic-like orbitals (the SIESTA package) and in some test calculations also the basis of plane waves (the VASP package). Computational experiments have shown that the binding energy of Ti atoms with a defect-free nanotube is always lower than with defective ones, regardless of the used approximation for the exchange-correlation functional (LDA or GGA). The binding energies predicted in the LDA approximation are noticeably higher than in the GGA approximation (up to ~15% for the (7, 7) tube and up to ~50% for the (11, 0) tube). The strongest coupling occurs when the titanium atom is adsorbed on a nanotube with a single vacancy. The resulting configuration can be considered as a defect in the substitution of one carbon by a titanium atom.
Energy Barriers for the Spontaneous Magnetization Reversal of the Atomic Co Chains on Pt(664) Surface in the Model with Dzyaloshinskii–Moriya Interaction
Authors: Kolesnikov S. V. , Sapronova E. S.
Published: July 2024

The analytical approach has been developed in the framework of the continuous XY-model. This approach allows calculating the spontaneous magnetization reversal time of finite-length atomic chains on the metallic surface. The interaction of the magnetic moments of atoms is described by the classical Hamiltonian, which includes the Heisenberg exchange interaction, the Dzyaloshinskii–Moriya interaction, and the magnetic anisotropy energy. Using the Co/Pt(664) system as an example, it has been shown that the proposed method is in a good agreement with the results of the numerical simulation in the limit of short and long atomic chains. And for atomic chains of intermediate length, it can be used to estimate an upper bound on the spontaneous magnetization reversal time. We obtained the dependences of the spontaneous magnetization reversal time of finite-length Co chains the value of the exchange integral, parameters of the magnetic anisotropy, and also on the value of the projection of the Dzyaloshinskii vector onto the axis perpendicular to the plane containing the magnetic moments of the atoms. It is shown that the proposed method has a wide range of applicability both in terms of temperature and the values of the physical parameters characterizing the magnetic properties of the atomic chains.

Published: July 2024

The growth and evolution of one-dimensional nanostructures on metal stepped surfaces were studied using the kinetic Monte Carlo method. The distribution of nanochain lengths was shown to change differently when the substrate was heated and cooled. Regularities are described that connect the nature of changes in the length distribution and the relative values of diffusion barriers for adatoms on the surface, which will make it possible to predict the length distribution of the resulting one-dimensional nanostructures.
Quantum Size Effect of Bloch Wave Functions of Ultra-High Energy Electrons in a Thin Single-Crystal Film
Authors: Shkornyakov S. M.
Published: July 2024

The reflection coefficient of ultra-high-energy electrons (~1 MeV) at their normal incidence on a thin single-crystal film is calculated. It is shown that even at such high particle energies, the quantum size effect of the Bloch waves formed in the film is noticeably manifested. Narrow Bragg reflection peaks are found to appear at certain electron energies. A formula is given that determines their position and intensity on the reflection curve. A comparison is made of reflection coefficients at medium, high and ultra-high particle energies.

Effect of irradiation on grain size and texture in Mo and Ta films
Authors: Andrianov V. A. , Bedelbekova K. A.
Published: July 2024

Implantation of heavy ions into metal matrices leads to the creation of a high concentration of radiation defects. X-ray diffraction studies of Mo and Ta foils implanted with 57Fe ions have been carried out. It is shown that the implantation of Fe ions does not significantly affect the lattice parameters. It has been established that irradiation leads to broadening of diffraction lines and a decrease in the size of crystal grains. The Mo and Ta foils with {100} orientation are found to be highly textured. Irradiation with Fe ions has no noticeable effect on the texture. However, subsequent annealing at a temperature of 700°С weakens the texture on the irradiated side for Mo and Ta foils without affecting the texture of the nonirradiated side.
Modeling of the influence of field electron emission from a cathode with a thin insulating film on its sputtering in a gas discharge in a mixture of argon and mercury vapor
Authors: Bondarenko G. G. , Kristya V. I. , Savichkin D. O. , Fisher M. R.
Published: July 2024

A model of the low-current gas discharge in a mixture of argon and mercury vapor in the presence of a thin insulating film on the cathode surface is proposed. The model takes into account that in such a mixture a substantial contribution to the ionization of the working gas can come from the ionization of mercury atoms during their collisions with metastable excited argon atoms. In the discharge, positive charges accumulate on the film surface, creating an electric field in the film sufficient to cause field emission of electrons from the cathode metal substrate into the insulator. Such electrons are accelerated in the film by the field and can escape from it into the discharge volume. As a result, the effective yield of ion-electron emission from the cathode increases. The temperature dependences of discharge characteristics are calculated and it is shown that, due to a rapid decrease in the concentration of mercury vapor in the mixture with decreasing temperature, the electric field strength in the discharge gap and the discharge voltage increase. The presence of a thin insulating film on the cathode can result in an improvement in its emission characteristics and a significant reduction in the discharge voltage. This causes a decrease in the energies of the ions and atoms bombarding the cathode surface, and, consequently, in the intensity of cathode sputtering in the discharge.

Published: July 2024

The study of the fractal properties of the surface of Nd100–xFex alloys in a wide range of concentrations х (х = 20–90) was carried out in the framework of the fractal thermodynamics model. To this end, we performed an analysis of images obtained by (scanning electron?) microscopy of the surfaces of a series of Nd100–xFex alloys synthesized by induction melting. A high degree of proximity of the surface structure of all the studied samples, both before and after etching, to fractals is shown. The values of the parameter δ characterizing the relative deviation of the studied samples from the fractal are in the range of 0.017–0.029. Three-dimensional diagrams of the fractal parameters Sf , Tf , Ef , x and two-dimensional diagrams of the same parameters: Sf , Tf , Ef , x, reflecting the nature of the state of the surfaces of Nd100–xFex alloy samples before and after etching, are constructed. For all investigated samples of alloys, the values of the parameters of the fractal equations of state arecalculated. The correlation of the maximum value of the coercive force Hc = 4.8 kE with the values of fractal entropy Sf = 39.86, fractal temperature Tf = 529, and fractal dimension D = 2.6530 of the Nd100–xFex alloys at x = 20 has been established.

Characterizing Nanopore Sequencing Artifacts with Deep Learning
Authors:   , Zhou David
Published: July 2024

Oxford Nanopore sequencing is a revolutionary new technology for sequencing DNA molecules in long stretches. However, it has a significantly higher error rate than conventional short-read sequencing, resulting in numerous sequencing artifacts. These artifacts can be indistinguishable from low frequency somatic variants, which is a roadblock for cancer diagnosis using liquid biopsies. In this study, benchmarked human genome samples from Genome in a Bottle were used to create a dataset of labeled variants, including artifacts and true variants. Variant features, including sequence context, were used to train various deep learning models. The multi-input neural network combining sequence context features and other variant features resulted in higher validation accuracy (0.871) than the other non-sequence context features alone (0.853), demonstrating that the sequence context surrounding a variant has some predictive power regarding whether a called variant is a sequencing artifact or a true variant.
Mitigating Learning Bias in Healthcare Datasets
Authors:   , Kumbhalwar Samyak Jagdish
Published: July 2024

CVDs have been a major cause of deaths worldwide with WHO reporting 17.9 million deaths annually. Although there are advancements in the treatment of these diseases, most of the fatalities are a result of untimely diagnosis. Active research is going on to collect data points and risk factors related to these diseases, which can enable early diagnosis. Of the datasets available, many researchers have employed different ML models to predict/detect the prevalence of heart diseases. Many employed Tree based, regression models [3, 6]. Few also tried ensemble approaches [1, 2, 4]. These healthcare datasets are generally found to be imbalanced. This can lead to learning bias with ML models predicting the dominant class better. Few researchers tried to tackle this problem by using common sampling techniques such as SMOTE and random oversampling [4, 5]. However, there hasn’t been an extensive study done to evaluate different techniques for this disparity in the healthcare datasets. This project aims to employ advanced techniques, e.g. Generative Adversarial Networks (GAN) based architectures and weighted Random Forest, to counter this disparity found in CVD datasets and thus, enable the ML models to learn better and predict.

Authors:   , Phukon Prathana
Published: July 2024

Online reviews significantly influence consumer behavior and business reputa- tions. Detecting fake reviews is important for maintaining trust and integrity in these platforms. In this project, an application of Aspect-Based Sentiment Analy- sis (ABSA) called FakeDetectionGCN is introduced to distinguish genuine feedback from deceptive content. The idea is to analyze sentiments related to specific aspects (features) within reviews. Graph Convolutional Networks (GCNs) are used to model the complex contextual dependencies in the review texts. Additionally, SenticNet, an external semantic resource, is integrated to enhance the understanding of sentiments in the reviews. This model is capable of identifying both human-generated as well as computer-generated fake reviews. It has been evaluated on two types of datasets and has shown strong performance across both. Through this project, we contribute to the effective detection of fake reviews and maintaining a trustworthy online review ecosystem.

Published: July 2024

In the battle against the COVID-19 pneumonia outbreak, which is brought on by the coronavirus strain SARS-Cov-2, radiological chest exams, such as chest X-rays, are crucial. In order to understand the unique radiographic characteristics of COVID-19, this research looks into classification models to distinguish chest X-ray images based on Radiomics features. This study is performed with datasets composed of 136 segmented chest X-rays, which were used to train and test the categorization algorithms. First and second-order statistical texture characteristics were extracted from the right (R), left (L), superior, middle, and bottom lung zones for each lung side using the Pyradiomics collection. Data was divided into training (80%) and test (20%) groups for feature selection. After assessing the respective feature significance and confirmation accuracy, the most pertinent Radiomics features were chosen. A model of lung segmentation based grey level pixels was used to evaluate support vector machines (SVM) as possible classifiers (AUC = 83.7%). Our research reveals a preference for the upper lung zone and a preponderance of Radiomics feature selection in the right lung. Our future research will concentrate on COVID-19 categorization and segmentation for more precise forecast using a hybrid method based on SVM and Radiogenomics features.

BACKGROUND: Low-grade gliomas (LGG) are a variety of brain tumors that show different clinical outcomes. The methylation of the GSTM5 gene has been noted in the development of LGG, however, its prognostic importance remains uncertain. OBJECTIVE: The objective of this study was to examine the correlation between GSTM5 DNA methylation and clinical outcomes in individuals diagnosed with LGG. METHODS: Analysis of GSTM5 methylation levels in LGG samples was conducted using data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets. The overall survival based on GSTM5 methylation status was evaluated using Kaplan-Meier curves. The DNA methylation heatmap for particular CpG sites in the GSTM5 gene was visualized using the “pheatmap” R package. RESULTS: The study analyzed that LGG tumors had higher levels of GSTM5 methylation than normal tissues. There was an inverse relationship discovered between GSTM5 expression and methylation. LGG patients with hypermethylation of GSTM5 promoter experienced a positive outcome. Age, grade, and GSTM5 methylation were determined as independent prognostic factors in LGG through both univariate and multivariate Cox regression analyses. CONCLUSION: Methylation of GSTM5 DNA, specifically at certain CpG sites, is linked to a positive outlook in patients with LGG. Utilizing the “pheatmap” R package to visualize GSTM5 methylation patterns offers important information for identifying prognostic markers and therapeutic targets in low-grade gliomas.

BACKGROUND: Ultrasound imaging has been widely used in clinical examination because of portability, safety, and low cost. However, there are still some main challenges of imaging quality that remain in conventional ultrasound systems. OBJECTIVE: Improving image quality of SA-based methods using an improved imaging mode named far-focus compound (FSC) imaging. METHODS: A far-focus compound (FSC) imaging based on full-aperture transmission and full-aperture reception is proposed in this paper. In transmission, it uses the full aperture to transmit the focused beam to ensure image resolution and emission of sound field energy. In reception, the full aperture is used to receive the reflected beam to ensure the image quality. A lag-one coherence-based zero-cross factor (LOCZF) is then implemented in FSC for improvement of contrast ratio (CR). The LOCZF uses lag-one coherence as zero-cross factorâs adaptive coefficient. Comparisons were made with several other weighting techniques by performing simulations and experiments for performance evaluation. RESULTS: Results confirm that LOCZF applied to FSC offers a good image contrast and simultaneously the speckle pattern. For simulated cysts, CR improvement of LOCZF reaches 194.1%. For experimental cysts, CR improvement of LOCZF reaches 220%. From the in-vivo result, compared with FSC, CR improvement of LOCZF reaches 112.7%. CONCLUSION: Proved gCNR performance. In addition, the LOCZF method shows good performance in experiments. The proposed method can be used as an effective weighting technique for improvement of image quality in ultrasound imaging.

BACKGROUND: Electronic foetal monitoring (EFM), a method to monitor foetal intrauterine conditions and foetal reserve capacity, is the most extensively used intrauterine monitoring technology in obstetrics. OBJECTIVE: This study aims to compare the Thoth wearable foetal electrocardiogram (foetal ECG [FECG]) monitoring system with a traditional Doppler foetal heart monitoring system before labour to investigate their respective values in clinical application. METHODS: A total of 393 pregnant women admitted to our hospital between 2020 and 2022 participated in this study. They were recruited using the convenience sampling method. We employed a paired design to assess the confusion rate, trend overlap, and foetal heart rate/ECG monitoring consistency, whereas a completely randomised design was used to measure pregnancy outcome indicators. The participants were divided into two groups using a random number table: the Thoth group (n= 196) and the traditional Doppler group (n= 197). Each group was monitored using the corresponding system. RESULTS: The Thoth monitor demonstrated a lower confusion rate compared with the traditional Doppler monitor (0.25% vs 2.04%; χ2= 5.508, P= 0.019). The trend overlap in foetal heart rates was consistently 100%, with 91.2% of readings showing a consistency rate of ⩾ 95%. Additionally, the Thoth monitor recorded a higher cumulative interruption time in the foetal heart rate curve (12.13 ± 2.22 vs 21.02 ± 2.34; t= 18.471, P< 0.001) and more abnormal ECGs (21.21 ± 4.32 vs 18.21 ± 2.91; t= 7.582, P< 0.001) than the traditional Doppler system. CONCLUSION: The Thoth wearable FECG monitor offers several advantages over the traditional Doppler foetal heart monitoring system. These include a reduced confusion rate, more accurate data collection, a lower rate of clinical misjudgement, reduced workload for medical staff, and enhanced comfort during vaginal delivery. The rates of emergency caesarean sections and neonatal asphyxia in the Thoth group were marginally lower than those in the Doppler group, which may be attributed to issues such as ECG disconnection or interference from the maternal heart rate.

BACKGROUND: Deep vein thrombosis (DVT) of the lower limbs is a venous reflux disorder caused by abnormal coagulation of blood components, primarily characterised by swelling and pain in the lower limbs. Key risk factors include prolonged immobility due to bed rest, pregnancy, postpartum or postoperative states, traumas, malignant tumours and long-term contraceptive use. OBJECTIVE: To investigate the application of real-time shear wave elastography (SWE) in diagnosing lower-limb deep vein thrombosis (DVT). METHODS: A total of 91 patients with DVT were selected and divided into three groups: acute phase (n= 29), subacute phase (n= 30) and chronic phase (n= 32). The Young’s modulus of the patients was measured using real-time SWE. The diagnostic efficacy of Young’s modulus was evaluated by ROC curves. The hardness differences in Young’s modulus across different parts of the same thrombus (head, body and tail) were measured using SWE. RESULTS: Before treatment, significant differences were observed in Young’s modulus among patients with DVT (P< 0.001). Following anticoagulant therapy, catheter-directed thrombolysis and systemic thrombolysis, significant differences were noted in Young’s modulus among patients at the same stage but receiving different treatments (acute phase: P= 0.003; subacute phase: P= 0.014; chronic phase: P= 0.004). Catheter-directed thrombolysis had greater efficacy than anticoagulant therapy. The area under the curve for SWE in staging patients was 0.917, with a sensitivity of 92.36% and specificity of 93.81%. Significant differences in Young’s modulus were found between the thrombus head and thrombus body and tail but not between the thrombus body and thrombus tail. CONCLUSION: Measurement of Young’s modulus using SWE can serve as an auxiliary means of evaluating staging, predicting pulmonary embolism and selecting treatment in patients with DVT.
