Device for dynamic calibration of pressure sensors
Authors: Tykhan Myroslav , Markovych Viktor , Heneralov Vitalii , Milian Marian
Published: February 2025

Modern devices for dynamic calibration of pressure sensors (shock tubes, power simulators of pressure impulse, etc.) have a number of drawbacks stemming from the principles of creating a test impact. Besides, the problem of rational choice of the method of calibrating pressure sensors depending on the dynamic parameters of the sensor and the required test accuracy has not been solved for modern test systems. The paper presents a solution to the problem of correlation between the test parameters, dynamic parameters of the pressure sensor and test accuracy. The obtained analytical dependencies of such a relationship make it possible to reasonably select or develop a method for studying the dynamic characteristics of sensors. Based on theoretical studies, the principle of creating a test impact has been proposed, and a method and device for implementing dynamic calibration of pressure sensors have been devised. The developed device allows the transient response of the sensor to be obtained, as well as setting the decay time of its natural vibration. Based on the transient response, other dynamic characteristics of the sensor, namely the impulse transient and frequency response, can be calculated.
Power-of-sine windows as generalized maximum sidelobe decay windows – theory and properties: a review and new results
Authors: Borkowski Józef , Matusiak Adam
Published: February 2025

The paper presents the theoretical properties of power-of-sine time windows, including the property of maximum sidelobe decay. This family of windows is a generalisation of the widely known Maximum Sidelobe Decay (MSD) windows and is referred to as Generalised Maximum Sidelobe Decay (GMSD) windows. GMSD windows are used in methods such as DFT spectrum interpolation (IpDFT), due to their desirable properties for such applications. The paper presents the key results, including the analytical form of the frequency characteristics of GMSD windows and some of their properties. The formulas derived are useful for describing these properties.
Application of wavelet exponential window denoising and dynamic uncertainty in acoustic emission
Authors: Fang Lide , Sun Jianzhang , Zheng Meng , Zeng Qiaoqiao , Dong Fang , Feng Yue
Published: February 2025

The gas-liquid two-phase acoustic emission (AE) signal contains rich flow information, but it is also accompanied by a large number of interference signals. To accurately extract the characteristics of gas-liquid two-phase flow, the removal of interference signals is very important. In this paper, AE technology is used to detect the signal of gas-liquid two-phase flow in a vertical pipeline. The support degree of the sensor is checked by the trust function to confirm the consistency of the sensor and eliminate wrong data. The decomposition level of the wavelet base and wavelet transform is determined by four parameters such as the signal-to-noise ratio. By comparing the wavelet exponential window smoothing method and the wavelet soft threshold method, the wavelet exponential window smoothing method which is more suitable for the denoising effect is selected, and the real-time denoising effect is evaluated by using the measurement dynamic uncertainty theory. The results show that the wavelet exponential window denoising method improves the signal-to-noise ratio, reduces the energy leakage during denoising, and significantly improves the pseudo-Gibbs phenomenon, while dynamic uncertainty can effectively evaluate the denoising effect of AE signals.

Published: February 2025

Endovascular aneurysm repair (EVAR) has emerged as the primary treatment option for abdominal aortic aneurysm (AAA) surgeries. The intricate hemodynamics within the AAA region often leads to various complications in post-stent-graft placement, such as endoleaks. Thus, the objective of this study was to assess the risk of stent-graft migration attributable to the appearance of endoleaks, employing spatial configuration analysis and wall shear stress (WSS) assessment. AngioCT data from 20 patients aged 50–60 years, who had undergone stent-graft placement at the Medical University of Vienna, were utilized. Three-dimensional geometries were reconstructed using ANSYS software (ANSYS, Canonsburg, Pa, USA) for blood flow simulation. The blood flow was assumed to be incompressible and laminar. The stent-graft’s area and height were scrutinized, alongside the formulation of a shape factor connecting the real stent-graft’s volume with a virtually reconstructed cylinder. Prostheses with endoleaks exhibited an averageWSS of 328.23 ± 107.63 Pa, while the average WSS within the endoleak area was 30.00 ± 9.57 Pa. In contrast, prostheses without endoleaks displayed a WSS of 367.90 ± 119.42 Pa. Computational Fluid Dynamics (CFD) algorithms facilitated the analysis of WSS values pre- and post-endoleak appearance, as well as within the endoleak region. Additionally, the proposed shape factor facilitated the spatial configuration of stent-grafts with and without endoleaks, incorporating the pushing forces.

Authors: Cao Xueshan , Zhao Guanqi , Peng Huiyuan , Mi Yuanqi , Zhou Mengge , Guo Yang
Published: February 2025

Background: The hypertension risk in the co-occurrence of allergic diseases remains largely unknown. Objective: We aimed to investigate the association between allergic diseases co-occurrence pattern and hypertension morbidity and mortality, and to evaluate
additive interaction effects between allergic diseases. Methods: A nationally representative population from the U.S. National Health Interview Survey 2012 was enrolled. Hypertension and five specific allergic diseases, including asthma, allergic rhinitis (AR), food allergy
(FA), eczema, and other allergy (OA), were determined. Hypertension mortality was identified until December 31, 2019. We evaluated additive interaction effects between two allergic diseases on hypertension risk: relative excess risk due to interaction (RERI) and attributable proportion of
joint effect due to interaction (AP) (shown as percentages) were calculated. For modifiable lifestyle factors with significant heterogeneity in the subgroups, we examined the effect modification. Results: Totally, 34,392 participants were enrolled. Four co-occurrence patterns
of two allergic diseases were associated with an increased risk of hypertension, including AR + FA (odds ratio [OR] 2.25 [95% confidence interval {CI}, 1.52‐3.35]), eczema + OA (OR 1.94 [95% CI, 1.14‐3.30]), AR + eczema (OR 1.76 [95% CI, 1.18‐2.64]), asthma + AR (OR 1.67
[95% CI, 1.33‐2.08]). Five co-occurrence patterns of three allergic diseases were associated with increased risk of hypertension. Additive interactions were seen in AR + FA (RERI, 0.65; AP, 29%), eczema + OA (RERI, 0.43; AP, 22%), AR + eczema (RERI, 0.21; AP, 12%), and asthma + AR (RERI,
0.05; AP, 3%). The significant association between asthma + FA and hypertension was only seen among participants with a body mass index (BMI) ≥ 30 kg/m2 (p = 0.021). With a median follow-up of 7.5 years, one co-occurrence pattern of asthma + FA showed a significant increased
risk of hypertension mortality (hazard ratio 4.32, 95% CI: 1.52‐12.23), with an additive interaction was observed (RERI, 2.33; AP, 52%). Conclusion: We identified several allergic diseases co-occurrence patterns with a significantly increased risk of hypertension
morbidity and mortality. Potential biologic additive effect among allergic diseases and effect modification of BMI was found. Precision primary prevention of hypertension is necessary for patients with co-occurring allergic diseases.

Opinión pública sobre las Fuerzas Militares en el contexto del conflicto armado colombiano (2017-2022)
Authors: Pedraza Martínez Veronica , Martínez Gutiérrez Ricardo
Published: February 2025

Este artículo analiza el cubrimiento de los medios de comunicación (radio, prensa, televisión y redes sociales) frente a la opinión pública en el contexto del conflicto armado interno colombiano. Se presentan las principales características del conflicto que reflejan estos medios y su influencia en la imagen de los actores del conflicto ante la opinión pública, en particular sobre la eficacia y legitimidad de las Fuerzas Militares. Con una metodología descriptiva mixta, no exhaustiva, basada en una encuesta a expertos, este análisis combina visiones objetivas y subjetivas con enfoques macro y micro sobre el tema. Se muestra cómo la actitud y posición de los medios en el conflicto ha variado frente a los cambios de las fuerzas contendientes, siguiendo sus propias lógicas ante la opinión pública; unas veces obsecuentes ante grupos alzados en armas y otras indiferentes frente a los esfuerzos de las Fuerzas Armadas.

Published: February 2025

This study demonstrates the potential of investigating and analyzing the anatomical structure of Miscanthus × giganteus (Giant Miscanthus) leaves using light microscopy with the OpenFlexure Microscope. Research on this crop is crucial for understanding its morphological and physiological characteristics, which influence productivity and adaptation to diverse growing conditions. Key features of leaf structure, including the epidermis, stomatal apparatus, and vascular system, determine the efficiency of photosynthesis, transpiration, and the accumulation of pollutants. These factors are essential for enhancing the productivity of this crop and optimizing its use in ecological projects, particularly in phytoremediation.
Accessible, functional, and high-precision tools are essential for the anatomical analysis of plants. The OpenFlexure Microscope facilitates high-resolution imaging and detailed examination of cellular structures in leaves, such as the epidermis, mesophyll, and veins, as well as their interactions. With its 3D-printed design and integration with digital imaging technologies, the OpenFlexure Microscope enhances access to microscopy, even in laboratories with limited resources or in field-based studies.
This article presents the anatomical features of Miscanthus × giganteus leaves, which are critical for further breeding and agronomic research. The advantages of using the OpenFlexure Microscope in botanical studies are highlighted, particularly in the examination of plants with complex morphological structures. The method allows for a comprehensive analysis of both microscopic and macroscopic leaf characteristics.
The findings indicate that the leaf structure of Miscanthus × giganteus is well-adapted to various climatic conditions, contributing to the plant’s resilience to stress factors. The study concludes that analyzing leaf anatomy is essential for advancing knowledge of the growth and development mechanisms of this crop. The results could contribute to the improvement of breeding programs and the development of effective cultivation strategies for Miscanthus in environmentally challenging sites.
Thus, the anatomical study of Miscanthus × giganteus using the OpenFlexure Microscope represents an important step toward optimizing its use as an energy crop and a phytoremediation tool. This approach combines economic benefits, ecological sustainability, and scientific innovation, addressing contemporary challenges in energy and environmental science. Integrating the OpenFlexure Microscope into research in Ukraine could significantly enhance local scientific capacity, improve the accessibility of modern tools for plant analysis, and provide higher-quality data for bioenergy and agricultural research.

OF DIFFERENT MANUFACTURES
It was established that spectroscopic and chromatographic methods of analyzing were used to determine sucralose. Given that the spectroscopic method of analysis requires specific preparation of samples is insufficiently accurate and sensitive, and the chromatographic method is expensive, the electro-analytical method of determination was chosen for the research. This is justified by the structure of the molecule (it contains functional groups that can be oxidized electrochemically). Electrochemical experiments were carried out using a potentiostat-galvanostat on a three-electrode setup with a glassy carbon electrode as a working electrode, a platinum electrode as an auxiliary electrode and a silver chloride electrode for comparison. The study utilized non-carbonated beverages Continente (Portugal) and Xixo (Hungary), as well as carbonated beverages Sumol Zero (Portugal) and Fanta Shokata (Ukraine).The manufacturer indicated the presence of sucralose in all of them. Based on the conducted research and corresponding calculations, it was established that the beverages are safe for consumption.
Natural processes of photo-, photoelectro-, and electrodegradation in soil and wastewater reduce the problems of sucralose accumulation in the environment. Therefore, to prevent diffusion to the anode space with the release of gaseous chlorine, membrane electrolysis is applied (the membrane is made of polyvinylpyridine), which separates the cathode and anode spaces and does not allow chloride ions to reach the anode. In this case, water electrolysis or electrooxidation of hydroxyl ions occurs at the anode with the formation of gaseous oxygen.
Electroanalytical determination of sucralose was also conducted using the method of cyclic voltammetry. The fact that the electrochemical determination of sucralose took place can be judged by a gradual but sharp increase in the current value at certain potential values. In this case, the intensity of this increase depends on the concentration of the sweetener.
A solution with a neutral pH level was used as the background electrolyte. Materials based on carbon (graphite, carbon nanotubes) were used as the working electrode.
We proposed a new method for determining sucralose, associated with the dependence of the peak current value during its electrochemical oxidation on the concentration. At the same time, a linear relationship between the peak current value and the sweetener concentration is maintained.

This article presents an ecotoxicological evaluation of the impact of environmentally relevant concentrations of military-derived metals on aquatic organisms, using the common carp (Cyprinus carpio) as a model species. The study assessed total antioxidant activity, lipid peroxidation (LPO) intensity, oxidative protein modifications (OPM) levels, catalase and glutathione transferase activity, as well as glutathione levels in the brain, liver cells, and blood of the carp. Additionally, the activity of caspase-3 and acetylcholinesterase was examined under exposure to zinc (Zn), antimony (Sb), copper (Cu), and their mixtures with lithium (Li) and cadmium (Cd).
The results demonstrated significant alterations in the antioxidant defense system of the exposed organisms. Elevated LPO and OPM levels indicated intensified oxidative stress, while fluctuations in catalase and glutathione transferase activity reflected adaptive responses to metal toxicity. A decline in glutathione levels suggested depletion of antioxidant reserves. The study of caspase-3 activity provided insights into apoptotic mechanisms, whereas changes in acetylcholinesterase activity pointed to potential neurotoxic effects.
These findings are crucial for understanding the ecological risks associated with military-origin metal contamination in aquatic ecosystems. They provide valuable data for developing environmental regulations and mitigation strategies to address metal pollution and its effects on aquatic biota.
Performance Evaluation of Different NEMA Induction Motor Designs under the Effect of Unbalanced Supply Voltages
Authors: Ameen Hilmi F. , Hamad Hayder A. , Rasool Ali A.
Published: February 2025

Three-phase induction motors (IMs) are generally used in commercial, industrial, and domestic applications due to their advantages, such as good self-starting ability, simplicity, high reliability, cost-effectiveness, low maintenance, and ruggedness in construction. The IMs are exposed to different internal and external faults; one of the most popular external faults is unbalanced supply voltages. Unbalanced supply voltage is a popular and worldwide phenomenon that effectively decreases the characteristics of IMs. The present work shows the adverse effect of unbalanced supply voltages on the steady-state characteristics of all NEMA (National Electrical Manufacturers Association) designs of 20hp squirrel cage IMs (SCIMs). A symmetrical component is used to determine the performance of each NEMA design operating in different unbalanced supply voltage situations. The importance of this paper is that it likens different NEMA designs regarding torque-speed characteristics, efficiency, power factor, stator currents, rotor currents, torque pulsation, a ripple in rotor speed, and starting-up performances when subjected to over and under-unbalanced supply voltage conditions. Also, the MATLAB and Simulink environments have been utilized concurrently for simulation purposes.

L’art numérique au risque de l’expérience haptique/tactile. Ce que toucher par l’œil et voir par le toucher veulent dire
Authors: Colas-Blaise Marion
Published: February 2025

Dans cet article, il s’agit de se demander en quoi l’œuvre d’art numérique autorise ou appelle des expériences impliquant le toucher, plus ou moins médié par des dispositifs. L’accent est mis, d’une part, sur la contemplation haptique, que l’œuvre d’art numérique partage avec l’œuvre d’art non numérique, et, d’autre part, sur la tactilité visuelle, dont les modalités peuvent être spécifiques. Ainsi, deux séquences – toucher pour mieux être touché et être touché avant de toucher en retour – peuvent être dégagées. En même temps, il s’est avéré qu’une telle analyse des modalités de deux types de toucher différents exige une réflexion préalable sur la question tant débattue de la matérialité et de la texture de l’œuvre d’art numérique.

L’objectif de cet article est de présenter, d’une perspective à la fois phénoménologique et sémiotique, les stratégies de conception de l’expérience tactile dans les réalités virtuelles qui, au fil de l’histoire de l’interaction humaine-machine, ont promis le dépassement de la configuration désincarné et cybernétique de l’utilisateur. Parallèlement, nous observerons comment cette évolution a entraîné non seulement l’échec de certains dispositifs de retour de force, mais également le renforcement d’un imaginaire technologique dominé par la prédominance des interfaces utilisateur « naturelles ». Dans ce nouveau contexte, que l’article explorera à travers l’analyse d’un corpus d’images génériques, le sujet haptique n’est plus seulement humain mais aussi machinique, marquant ainsi le passage de la machine à « vision » à la « perception machine ».

Metal-FP: A hybrid molecular fingerprint to encode metal-based approved drugs
Authors: LÓPEZ LÓPEZ EDGAR , Medina-Franco José L.
Published: February 2025

Metal-based drugs have historically been used for different therapeutic and diagnosis applications. The necessity to discover and develop these kinds of compounds has contributed to the creation of computational strategies to accelerate these processes, however, most of them have limitations related to their computational cost, scalability, capacity to be used in different chemical contexts, and data accessibility. This study presents and physicochemically describes the first open metal-based drug database (MetAP DB). In parallel, this study introduces the first molecular metal-based fingerprints (Metal-FPs) representation capable of codifying data related to the presence of metals, their valence and oxidation state, the presence of specific functional groups, and the atom connectivity of metal-based compounds. Namely, this work aims to propose a general protocol to encode descriptors of metal-based approved drugs systematically.

Published: February 2025

The chemotactic guiding of particles using chemical gradients is an important area of research because of possible applications in drug and cargo delivery to specific locations. In addition, the experimental demonstration of non-reciprocal interactions in active systems is of fundamental importance. We have developed a new microchannel architecture that allows reactive particles to be exposed to imposed chemical gradients for a long time under flow-free conditions. Using this setup, we show that particles functionalized with the enzymes, urease, acid phosphatase, and glucose oxidase show positive chemotactic mobility in response to their respective substrate gradients in a concentration dependent manner. Most significantly, when combined, both acid phosphatase, and glucose oxidase-functionalized particles exhibit chemotaxis in response to a gradient of glucose-6-phosphate which acid phosphatase converts to glucose, the substrate for glucose oxidase. These findings underscore the significance of chemical gradient in directing particle movement, offering insights crucial for understanding complex biological processes such metabolon formation and chemotactic signaling. Additionally, our work constitutes the first step in designing intelligent functional assemblies where populations of particles with different functions coordinate their behavior.

Published: February 2025

Heteroaryl substituents are important building blocks of functionalized organic compounds in drug discovery, materials science, and catalysis. Quantitative descriptions of steric and electronic properties of heteroaryl substituents are essential in establishing structure-activity relationships and predicting reactivity and properties of heteroaromatic compounds. We introduce HArD, a HeteroAryl Descriptors database, comprising DFT-computed steric and electronic descriptors of 31,500 heteroaryl substituents. The database features heteroaryl substituents comprising 5- and 6-membered rings as well as 5,6- and 6,6-fused ring systems. Different regioisomers and additional substituents on the heteroaromatic ring were included to describe the diverse chemical space of heteroaryl substituents. The database includes 65 descriptors such as buried volume and Sterimol parameters to describe steric effects, atomic charges and HOMO/LUMO coefficients and energies to describe electronic effects, and Harmonic Oscillator Model of Aromaticity (HOMA) values describing aromaticity. In addition, we developed Hammett-type heteroaryl substituent constants (σHet) based on computed heteroaryl carboxylic acid pKa values, which aim to extend the broadly used Hammett constants (σp and σm) from substituted phenyl groups to substituted heteroaryl groups.
