Published: December 2024

Background: Post-cesarean pain management remains challenging, balancing effective analgesia with minimizing adverse effects on maternal-newborn bonding and breastfeeding. This study compared the efficacy of combined non-opioid rectal suppositories versus traditional intramuscular pethidine for post-cesarean pain management. Methods: In this prospective, randomized, single-blind study, 100 patients undergoing cesarean section were allocated into two groups of 50 each. The suppositories group received diclofenac (50 mg) and paracetamol (1000 mg) suppositories every eight hours, while the pethidine group received intramuscular pethidine (75 mg) every eight hours for 24 hours. Primary outcomes included visual analog scale (VAS) pain scores and patient satisfaction. Secondary outcomes included time to first ambulation, rescue analgesic requirements, adverse effects, and breastfeeding success. Results: The suppositories group demonstrated comparable or lower pain scores, particularly after 8 hours (24-hour VAS at rest: 2.4 ± 0.9 vs 3.2 ± 1.1, p=0.001). Time to first ambulation was significantly shorter in the suppositories group (12.4 ± 2.8 vs 15.6 ± 3.2 hours, p=0.001). The suppositories group showed significantly lower incidence of adverse effects including nausea (16% vs 44%, p=0.002), vomiting (8% vs 30%, p=0.005), and sedation (4% vs 36%, p=0.001). Breastfeeding success rates were higher in the suppositories group (92% vs 76%, p=0.028), with higher patient satisfaction scores (median 4 vs 3, p=0.001). Conclusion: The combination of diclofenac and paracetamol suppositories provides effective post-cesarean analgesia with significant advantages over intramuscular pethidine, including fewer adverse effects, earlier mobilization, and improved breastfeeding success. This non-opioid regimen represents a viable first-line option for post-cesarean pain management.

Published: December 2024

As we enter the next era of autonomous driving, robo-vehicles (which serve as low-cost and fully compliant drivers) are replacing conventional chauffeured services in the mobility market. During just the last few years, companies like Waymo Inc. and Cruise Inc. have already offered fully driverless robo-taxi services to the general public in cities like Phoenix and San Francisco. The rapid evolution of autonomous vehicles is anticipated to reshape the shared mobility market very soon. This project aims to address the following open questions. At the operational level, how should modular units be allocated across multiple categories of customers (e.g., passenger and freight cabins), and how should they be matched in real time? How do we enhance system efficiency by dynamic relocation and swap of modular chassis? At the strategic or tactical level, how should the rolling stock resources (modular chassis, passenger and freight cabins) be planned, and where shall chassis swapping sites be located? How could any potential transaction cost for a chassis swap, such as the time required for a modular chassis to be assembled with a customized cabin, affect the optimal strategy and system performance? How can customer priorities (e.g., passenger vs. freight) affect system performance, and how can service providers manage demand by specific pricing scheme or discriminative customer service strategies? We conducted the following research tasks: (i) analytically derived systems of implicit nonlinear equations in the closed form, including a set of differential equations, to analyze the modular autonomous mobility system and to estimate the expected system performance in the steady state; (ii) conducted a series of agent-based simulation experiments to verify the accuracy of the proposed analytical formulas and to demonstrate the effectiveness of the proposed modular chassis services; and (iii) designed policy instruments to enhance transportation system performance.

Published: December 2024

A toxoplasmose é uma infecção amplamente disseminada na população, cuja soro prevalência varia de acordo com as regiões, sendo fortemente influenciada por condições sanitárias e fatores socioeconômicos. A gravidade da infecção causada pelo T. gondii pode variar de acordo com a condição imunológica, humoral e celular do indivíduo, pois pode ocorrer sintomas muito brandos, ausentes ou até em formas clínicas exuberantes. As formas clínicas graves ocorrem em indivíduos imunocomprometidos e em gestantes. Um dos maiores problemas associados à toxoplasmose é o desconhecimento e a falta de informações adequadas, tanto por parte da população quanto, dos profissionais de saúde, sobre os reais processos de transmissão da doença. A forma mais frequente de contaminação pelo T. gondii ocorre por meio do consumo de carnes contaminadas com oocistos, especialmente quando ingeridas cruas ou mal passadas. Além disso, oocistos esporulados presentes no ambiente são fontes potenciais de infecção. A ingestão de água contaminada, assim como o consumo de frutas e legumes mal lavados, também desempenha um papel significativo na disseminação da doença.

Authors: Xie Weiyu
Published: December 2024

With the continuous development of the market economy, the business environment of enterprises has become increasingly complex. As a critical component of corporate governance, internal auditing plays a vital role in regulating business operations. However, traditional compliance-based internal auditing can no longer meet the development needs of modern enterprises. Researching value-added internal auditing to provide more effective value-added services for enterprises has become a significant topic in current internal auditing research and practice. Based on value chain theory, this paper introduces the concept of value-added internal auditing, explores the differences between traditional internal auditing and value-added internal auditing, analyzes existing problems in the implementation of value-added internal auditing in enterprises, and proposes a framework for constructing a value-added internal auditing system through organizational restructuring, institutional improvement, and the optimization of operational mechanisms.

This study investigates the impact of Bragg reflector design parameters on the temperature characteristics of resonators operating on the principle of bulk acoustic wave (BAW) propagation. These devices are essential for frequency selection and signal generation in the gigahertz range, which is crucial for modern communication systems such as 5G and Wi-Fi. The resonators under study featured an aluminum nitride (AlN) piezoelectric layer and various types of Bragg reflectors composed of molybdenum (Mo), aluminum (Al), titanium (Ti), and silicon dioxide (SiO2) layers. Key parameters measured included resonance frequencies, quality factor (Q), phase-frequency characteristics, active conductance, piezoelectric coefficient d33, as well as equivalent electrical parameters, temperature coefficient of frequency (TCF), and surface roughness. The findings reveal that temperature variations significantly affect resonance frequencies and quality factors of the resonators. The most stable TCF values (from -18 to -21 ppm/°C) and high quality factor (Q = 915) were achieved with Al-Mo-SiO2 Bragg reflectors, making them ideal for applications requiring high-temperature stability. Resonators with Mo-Ti reflectors demonstrated high quality factor (Q = 900) and an impressive d33 coefficient, indicating high energy efficiency, though they exhibited greater temperature sensitivity (TCF from -66 to -78 ppm/°C). These results underscore the importance of careful material selection, precise Bragg reflector design, and surface roughness control to achieve optimal performance characteristics in BAW resonators.

Published: December 2024

The modern radio resource management techniques use classical queuing system models for the Industrial Internet of Things scenarios descriptions. However, the classical models assume the independent arrival and service flows of each request. This paper considers the impact of correlated arrival and service flows for RRM in a centralized wireless network. We present a problem of radio resource management in Industrial Internet of Things as a set of separated G|G|1 queues with dependent arrival and service flows. It is shown that a positive correlation between arrival and service flows allows reducing waiting time in the G|G|1 system. We propose the controllable correlation in arrival and service flows as a technique for radio resource management and formulate the research challenges required to apply in real-time schedulers in centralized wireless networks.

In mobile radio communication systems, access techniques utilizing orthogonal separation of available communication channel resources are now widely used. A capacity of such networks depends on a size of an orthogonal resource ensemble of the carrier. To increase a capacity and a number of users simultaneously accessed the networks a perspective technology of non-orthogonal multiple access might be implemented, the technology enables multiple users connected to the same orthogonal time-frequency channel unit. This technology eliminates a restriction on a number of simultaneously multiplexed user signals which arises from the size of an orthogonal resource ensemble. The paper focuses on the mobile system utilizing a new multiple access technology which is non-orthogonal multiple access. The system under study at the transmitting end of the base station employs precoding, which is based on Zero Forcing and Minimum Mean Square Error methods, it enables decorrelation of users to improve system performance. Well known demodulation algorithms are applied at the user receivers, which are Successive Interference Cancellation and Maximum Likelihood. Non-Orthogonal Multiple Access system using with the processing options above provides a gain in terms of users over traditional Orthogonal Multiple Access system.
Parameterized FFT application for signal processing space estimation in massive MIMO system
Authors:   Skolkovo Institute of Science and Technology, Bychkov R.A.
Published: December 2024

This paper is dedicated to the parameterized fast Fourier transform (FFT) applied for beamspace selection in multi-user (MU) mode of a multiple-input multiple-output (MIMO) receiver. The discrete Fourier transform (DFT) is widely used for beamspace selection due to its low implementation complexity via FFT. However, such a transformation causes performance loss in MU mode since the fixed DFT directions are not aligned with the signal's directions of arrival (DOA). This problem is being solved here via parametrization and optimization of the FFT. Three versions of trainable FFT are proposed, which are different in computational complexity and resulting beam space selection accuracy. It is analytically proven, that other parametrizations of FFT used for beamspace selection are just special cases of proposed algorithms. Each version of parametrized FFT is optimized for the specific problem of beamspace selection, and the computational complexity is analyzed. Simulation results for the MIMO receiver with the non-line-of-sight channel generated by the QuaDRiGa 2.0 tool show up to 2 dB performance gain compared to conventional FFT beamspace.

Purpose: the task of increasing the reliability, noise immunity and noise immunity of a radio signal at the stages of developing channel-forming radio communication means in the decameter range of radio waves can be solved on the basis of improving the methods of receiving and processing a radio sig nal. The medium of propagation of radio waves in the decameter range is characterized by statistically heterogeneous physical parameters. Thus, based on solving the problems of statistical communication theory, it is possible to determine the main parameters of the projected communication channels. The characteristics of the propagation medium are random variables, and a priori knowledge about the parameters of their distributions is the basis for algorithms implemented in radio receivers. The purpose of the present paper: is to develop a model of an interference-proof decametric communication channel, a radio receiving device that automatically monitors the quality of the received signal based on nonparametric rank statistics. Methods: the solution of the problem of stable assessment of the quality of the received signal is performed on the basis of statistical nonparametric methods of rank estimation, methods of the theory of radio wave propagation and methods of the theory of electrical connection. Novelty: the use of a nonparametric rank two-sample functional for evaluating received signals of multi-position frequency telegraphy (M-FSK) under conditions of nonstationarity of the distribution of a random variable over the duration of an information symbol is proposed, efficiency indicators are compared with the correlation evaluation functional. Practical relevance: increasing the reliability of receiving M-FSK signals in conditions of non-stationarity of a random process caused by general and interference fades in a decameter communication channel. A computer model of a noise-proof communication channel of the decameter range is proposed. The developed model provides an automatic calculation of the efficiency of the assessment performed in incoherent and rank signal detectors based on the simulation results. The developed functional of the rank assessment can be used to calculate the reliability index of an information symbol when implementing decoders of noise-resistant codes with the adoption of a "soft" solution.

Published: December 2024

This paper presents the results of modeling the properties of a differential auto generator based on the Colpitts circuit, made on a pair of complementary MOSFET transistors in MICROCAP environment using PSPICE models of active components in time and frequency domain. A comparative analysis of the energy characteristics and noise performance of the auto generator using the simplified model and the simulation results has been per formed, showing their good enough coincidence. The dependence of the generated frequency and amplitude of the output signal on the ambient temperature was obtained as a result of modeling. As calculations have shown its variation is less than in the scheme of a single-cycle auto generator built according to a similar scheme. The estimation of the noise power spectral density at the output of the differential auto generator has shown that its value does not exceed - 180 dBc/Hz and its value depends weakly on the ambient temperature. The results of modeling estimating the change in the amplitude of the output signal from the bias voltage on the nMOS transistor, which is a stable current generator, are obtained. The impact of a harmonic signal on its gate allowed us to evaluate the synchronization efficiency of the differential auto generator, to obtain the capture and retention bands depending on the amplitude of the synchronizing influence.
Development and evaluation of 6G transceiver positioning methods in the near field
Authors:   The Bonch-Bruevich SPbSUT, Fokin G.A.
Published: December 2024

Radio interface technologies of sixth-generation 6G networks continue the trends of improving 5G NR, among which the determining factors are the transition to the millimeter wave range, an increase in frequency bandwidth to hundreds of megahertz and an increase in the size of antenna arrays to several dozen at gNB base stations and UE user devices. Together with an increase in the density of trans ceiver devices and a corresponding decrease in the distance between the gNB and the UE to a few meters, the above factors lead to the need to take into account the spherical wave front and the near-field effect, which in networks of previous generations of decimeter waves when studying communication and positioning issues by radio engineering methods were usually neglected. In connection with the transition to the range of submillimeter or terahertz waves with a bandwidth of up to gigahertz and the further increase in the size of antenna arrays to hundreds and thousands, taking into account the near-field effect for 6G networks is already becoming mandatory. In positioning problems, the near-field effect can serve as an additional source of information due to the spherical wave front and, with proper spatial processing, increase the accuracy of coordinate estimates. Along with localization, near-field conditions also open up additional gNB and UE synchronization opportunities. This work is devoted to the development of mathematical and simulation models to establish the accuracy limits and conditions for the practical feasibility of single-position estimation of coordinates and synchronization of UE user device transmitters at the gNB receiving base station in near-field conditions. The presented mathematical formalization and software implementation of the single-position positioning method showed the practical feasibility of joint localization and synchronization of the transmitting UE user device through spatial processing of signals by composite arrays of the antenna array at the receiving base station gNB with an accuracy of several decimeters at a distance of the UE from the gNB to five meters in conditions of presence and absence of line of sight.

Published: December 2024

The aim of this article is to conduct a research of the delay values obtained using hardware simulation stands and a software model of the SpaceWire network operation. The results of the study should demonstrate how the data transmission characteristics differ between an actual onboard network and its software model counterpart. The testing utilized the comprehensive testing stand for onboard information networks SpaceWire from JSC "ISS" and the aerospace SpaceWire stand for research, certification, and testing at the SUAI. For the software modeling, the SpaceWire Automated Network Design and Simulation (SANDS) system was used. During the study, data transmission simulation was launched on two hardware stands, and delay values for each transmitted data packet were obtained. Using the same network structures and similar equipment characteristics, the network operation was modeled using SANDS. As a result, delay values for both implementations in hardware were computed and compared with the actual metrics. For small data packets, the differences in transmission delay values were significantly higher than for larger packets. This is attributed to the processing time of packet headers and increased delays due to frequent switching between ports. An important result is that the delay values obtained from all con ducted experiments differ only slightly, with a deviation of 0.1-4.5% for packets of lengths 1-2 KB, which is a very good result. It can be concluded that SANDS allows for obtaining highly accurate values that are close to those of real equipment, and it can become a primary tool for developers of SpaceWire onboard networks, reducing the timelines and costs of aircraft development.

Published: December 2024

Durante el período embrionario, el desarrollo del sistema nervioso implica la precisa migración de células precursoras neuronales. Alteraciones en el patrón de migración impactan en la organización neuronal causando trastornos, como la Dislexia, que se caracteriza por dificultades en el aprendizaje de habilidades académicas relacionadas con la lecto-escritura. Su patrón de transmisión genético heterogéneo no permite ofrecer un estudio diagnóstico específico. En este proyecto buscamos contribuir al diagnóstico de niños disléxicos “borderline” mediante el uso de los Biomarcadores Genéticos Externos como las huellas dactilares. Éstas evalúan la información obtenida para inferir si el individuo porta un haplotipo “protector” o un haplotipo “de riesgo” de desarrollar Dislexia. Se copilaron, caracterizaron y compararon los patrones dermatoglíficos (arco, bucle o verticilo) junto al cálculo de la proporción 2D:4D buscando identificar un factor “fenodesviante”, ocurrido en una ventana específica de tiempo durante el desarrollo embrionario, que causa en simultáneo una falla en la migración neuronal y un patrón dermatoglífico específico en el niño disléxico. Nuestros resultados concluyeron que: los Biomarcadores pueden ser utilizados como herramienta complementaria para el diagnóstico de Dislexia. Ser varón puede ser considerado como un factor de riesgo y los pacientes con Dislexia presentan una mayor proporción de huellas dactilares con diseños simples y número de crestas menor, siendo el bucle el más representativo. La mejor extremidad para estudiarlos es la mano izquierda y los mejores dígitos corresponden al dedo meñique y al dedo medio, presentando ambos grandes porcentajes de bucle.

Nonlinear Schrödinger Equations with Delay: Closed-Form and Generalized Separable Solutions
Authors: Polyanin Andrei D. , Kudryashov Nikolay A.
Published: December 2024

Nonlinear Schrödinger equations with constant delay are considered for the first time. These equations are generalizations of the classical Schrödinger equation with cubic nonlinearity and the more complex nonlinear Schrödinger equation containing functional arbitrariness. From a physical point of view, considerations are formulated about the possible causes of the appearance of a delay in nonlinear equations of mathematical physics. To construct exact solutions, the principle of structural analogy of solutions of related equations was used. New exact solutions of nonlinear Schrödinger equations with delay are obtained, which are expressed in elementary functions or in quadratures. Some more complex solutions with generalized separation of variables are also found, which are described by mixed systems of ordinary differential equations without delay or ordinary differential equations with delay. The results of this work can be useful for the development of new mathematical models described by nonlinear Schrödinger equations with delay, and the given exact solutions can serve as the basis for the formulation of test problems designed to evaluate the accuracy of numerical methods for integrating nonlinear partial differential equations with delay.

Authors: Yang Cheng , Zhang Chenxuan
Published: December 2024

Surface electromyography (sEMG) signal has been a hot research topic in the field of human-computer interaction technology in recent years, It is not disturbed by environmental factors such as light, temperature, and humidity, and has the advantages of high precision, fast response and non-intrusiveness. Through the application of sEMG signals, the intelligent device can accurately judge the person's movement intention. Convolutional neural networks (CNNs) and long short-term memory networks (LSTM) are considered to have better performance on sequence data. In this paper, three deep learning frameworks (1-dimensional CNN, 2-dimensional CNN, and CNN-LSTM) are used for the gesture recognition task of continuous sEMG signals and evaluated for recognition performance separately. The results show that the 2D-CNN has the best recognition effect, which achieved average recognition accuracy of 90.36%. The average recognition accuracy of the CNN-LSTM and 1D-CNN is 89.37% and 80.21%, respectively. In addition, the time-domain sliding window segmentation method was used to process the EMG signal sequences to ensure the objectivity of the evaluation processes of CNN-LSTM.
