External Radiation Assistance of Neutrinoless Double Electron Capture

The influence of electromagnetic radiation on nuclear processes is applied to an example of a neutrinoless double electron capture (0ν2ec). For cases with X-ray free-electron lasers (X-ray FELs) and/or inverse Compton X-ray sources, it was shown that such a decay can be significantly enhanced by tuning the system to the resonant conditions through the absorption and/or emission of a photon with the decay resonance defect energy Δ. In this case, the 0v2ec decay rate Γ2e of nuclide Z grew linearly with field intensity (S/Sz) up to the X-ray flux power Sm~Z6, while Sz~Z6 (Γ/Δ)2 with decay width Γ of a daughter atom. For the case of 78Kr → 78Se − 0ν2eL1L1 capture we find Sz~109 W cm−2 and Sm~1017 W cm−2 which indicate a possibility of increasing decay rate to eight orders of magnitude or even larger.

Effect of electromagnetic radiation on the electronic and thermoelectric properties of armchair edge silicene nanoribbons

We theoretically investigate the influence of electromagnetic radiation on the electronic and thermoelectric properties of armchair edge silicene nanoribbons. Specifically, we study the effects of varying the polarization (s or p) and incident angle (0, 30, 45, 60, and 90°) of radiation on the band structure, transmission function, density of states, Seebeck coefficient, and electronic figure of merit (ZTe) of the nanoribbons. Our results demonstrate that the electronic properties are highly dependent on radiation conditions due to their influence on electron transport. We find that the transmission function and density of states exhibit distinct polarization-dependent behaviors that highlight the role of the radiation's electric field orientation. Importantly, the ZTe shows significant modulation with the incident angle for both polarizations, achieving optimized values up to 0.18. These findings provide insights into controlling the electronic and thermoelectric properties of silicene nanoribbons using electromagnetic radiation. Our work underscores opportunities for developing silicene-based nanophotonic devices with enhanced performance through all-optical means. The demonstrated tunability via irradiation paves the way for potential applications such as optical switches, sensors, and next-generation optoelectronics using silicene nanoribbons.

The influence of electromagnetic radiation on the body of the honey bee

The paper presents data on the influence of electromagnetic radiation on the organism of honey bees. For this, three groups of bee families were formed. Bee families of the control group were kept under the influence of electromagnetic radiation from the Sun. In the 1st experimental group, offspring were exposed to radiation with a frequency of 2580 MHz. For this, we used a GZ-122 microwave generator with an output power of 1×10-12 W. Irradiation was carried out in a chamber isolated from light and shielded from microwave radiation, which was located in a thermally and sound-insulated room shielded from microwave radiation. In experiments with bee brood, the temperature was maintained at 35 °С in shielded TS-80 thermostats. Irradiation was carried out in the following mode: 9 hours of irradiation and 7 hours of pause (without irradiation). This cycle was repeated 3 times in a row. The bee families of the second experimental group were under the influence of the same generator, which irradiated the brood in the following mode: 16 hours of irradiation and 7 hours of pause (without irradiation). This cycle was repeated 3 times in a row. It was established that bees that developed under long-term artificial irradiation acquire the morphophysiological characteristics of bees with fewer reserve nutrients. Long-term radiation exposure negatively affects the storage of nutrients in the form of lipids by 25.69 % (P < 0.05), the reduction of total nitrogen by 16.93 % (P < 0.05). Such a negative trend was revealed against the background of a 14.1 % lower mass (P < 0.01) compared to bees that developed under natural irradiation.

FPGA implementation of memristive Hindmarsh–Rose neuron model: Low cost and high-performing through hybrid approximation

Recent memristive neuron models have improved the ability of researchers to describe the operation of biological neurons. We employ FPGA implementation for a memristive neuron model, FPGA implementation provides an improved hardware system for mimicking brain behavior, and provides a better understanding of neurological phenomena. In this manuscript, a memristive Hindmarsh–Rose neuron model taking into account the influence of electromagnetic radiation and two multiplierless approximations of this model are presented. These approximations are piecewise linear (PWL) model and hybrid model, which mimic the behaviors of the original model. In the hybrid model, power 2-based approximation and a novel approximation are used simultaneously. The proposed models were subjected to error analysis, revealing that the PWL model exhibited mean NRMSEs of 3.56% and 2.3% for bursting and spiking modes, respectively. On the other hand, the hybrid model displayed mean NRMSEs of 1.92% and 1.34% for bursting and spiking modes. According to the FPGA implementation results, the PWL model yields the overall resources saving of 75.82% and 47.8% speed-up. But in the hybrid model, by optimizing the approximation functions, in addition to obtaining higher accuracy, better results are provided with a 67.3% improvement in the maximum frequency and the 78.64% saving in hardware resources.

Возможности исследования процесса горения металлизированных энергетических конденсированных систем методом сверхвысокочастотного излучения

The paper considers processes of the electromagnetic radiation propagation at the frequency of 9.027 GHz (corresponding to the wavelength in vacuum of 33.2 mm) in the round-section waveguides of an experimental unit to determine the burning rate of the mixed energy-condensed systems under the high pressure conditions. Qualitative theoretical analysis of the electromagnetic radiation interaction with single metal and contrast dielectric particles in the carrier dielectric medium of a condensed system and arrays of metal and contrast dielectric particles distributed in space was carried out. The paper evaluates the influence of electromagnetic radiation, base material and filler particles on parameters of the resulting standing wave in the microwave unit waveguide for measuring the burning rate of an energy-condensed system, and assesses theoretically the qualitative effect of the filler content on the error in the microwave measurement system. Results of the experimental study of combustion of two model energy-condensed systems, as well as the exemplary model dielectric material (transformer oil) by the microwave method, were analyzed. Study results are the practical justification for introducing the microwave method in diagnosing combustion characteristics of the energy-condensed systems containing particles of the metallized filler

Experimental evaluation of the influence of electromagnetic radiation and acute alcohol intoxication on the indicators of mineral metabolism and antioxidant protection in erythrocytes and blood plasma of rats

The aim of the research was a comparative analysis of the effect of electromagnetic radiation and acute alcohol intoxication on the parameters of mineral metabolism and antioxidant protection in erythrocytes and blood plasma of rats. Materials and methods. The research was performed on 128 white non-linear rats. The study was conducted on five experimental models: acute ethanol poisoning, acute ethanol poisoning against the background of preliminary alcoholization, exposure to electromagnetic radiation for 1, 2 and 3 months. Spectrophotometrically determined the content of iron, copper, transferrin, ceruloplasmin and the activity of gamma-glutamyl transpeptidase in the blood plasma of rats, the content of glutathione in blood erythrocytes. Results and discussion. A unidirectional nature of changes in the indicators of antioxidant protection and mineral metabolism in acute alcohol intoxication and electromagnetic irradiation was established, which consists in a decrease in the content of iron, transferrin, an increase in the content of ceruloplasmin, glutathione, and gamma-glutamyl transpeptidase activity. At the same time, a decrease in the iron content and a change in the parameters of antioxidant protection in the blood plasma are more pronounced in acute ethanol poisoning than in electromagnetic irradiation. Conclusions. Ceruloplasmin, transferrin, glutathione and gamma-glutamyl transpeptidase are targets for the action of electromagnetic radiation and ethanol. Determination of the activity of gamma-glutamyl transpeptidase in blood plasma has a prognostic value for determining the degree of liver damage not only with alcohol intoxication, but also with electromagnetic irradiation of the decimeter range.

Thus, the developed composite ceramics have characteristics that allow them to be used in construction and in electronic devices for the purpose of effective shielding of harmful radio radiation, and the developed ceramics, according to the classification, can be classified as radio-absorbing.

Electromagnetic Radiation from High-Voltage Transmission Lines: Impact on UAV Flight Safety and Performance

Unmanned aerial vehicles (UAVs) have emerged as versatile tools across various sectors, including power distribution infrastructure. While UAVs offer significant advancements in the time and cost-effectiveness of energy distribution infrastructure inspections, such operations present several challenges. The main challenges include the risk of collision with transmission cables themselves and the high potential for electromagnetic interference caused by high-voltage power lines. This research investigates the strength of the electromagnetic field (EMF) emitted by high-voltage power lines while identifying potential concerns for UAVs operating nearby. The research team conducted a series of experiments to quantify the strength of magnetic, electric, and radiofrequency fields induced by power transmission lines. A thorough understanding of the magnitude and potential effects of EMF from power lines is of great importance when conducting UAV flights in their direct vicinity. This understanding is crucial not only for ensuring the safety of infrastructure inspection flights but also for the safety of all UAV flights carried out near high-voltage lines. Our study contributes to the body of knowledge concerning the influence of electromagnetic radiation from high-voltage transmission lines on UAVs, providing valuable insights into mitigating risks associated with UAV flights in critical infrastructure inspections, as well as other operations.

Simulation and experimental research on electromagnetic radiation from suspended permanent magnetic levitation train

With the continuous development and innovation in the field of global magnetic levitation technology, the suspended permanent magnet maglev rail transit system has emerged. At present, no mature relevant technical standard references are available in the world. To study the electromagnetic radiation problem of the permanent magnet maglev train system, we use the finite element method to simulate and analyze the Halbach array track of different combinations of suspension modules, and the six-channel high-precision magnetic field test system is used to test and compare the actual engineering magnetic fields. The results show that the permanent magnet magnetic suspension rail transit system can shield the magnetic energy of the suspension module in the rail beam to reduce the influence of electromagnetic radiation. With the increase in suspension height between the rail and vehicle magnets, the generated magnetic field intensity exhibits a significantly weakening trend. The magnetic field energy of the permanent magnet maglev train is maintained at the centimeter level. Combined with the actual project, the passengers on the train and pedestrians, and residents along the red rail are not affected by the magnetic field intensity of the permanent magnet. This paper provides a theoretical basis for resolving people’s concerns about the electromagnetic radiation of maglev trains, and provides important theoretical support for the development of maglev rail transit.

Several factors affect the electromagnetic environment changes generated underneath high-voltage transmission lines. This article carries out a study on the impact of the electromagnetic environment on high-voltage transmission lines based on different tower structures, voltage levels, conductor layouts, conductor parameters, and other full range of engineering factors. First, the model of wire three-phase phase sequence, ground height, horizontal phase spacing, wire splitting number, split spacing, and model values are built. By continuously adjusting and optimizing the parameters, the electromagnetic environment distribution curve at 1.8 m above the horizontal plane is obtained. Then, according to the characteristic analysis of the distribution law after optimization, the simulation results under some typical factors are compared with the standard limits. Simultaneously, the effect of this optimization is verified by comparison with relevant literature. Finally, some suggestions on the optimization of the pole tower structure, transmission line parameters, and the influence of electromagnetic radiation in transmission line corridors are proposed in high-voltage transmission line projects, which may potentially have constructive contributions and value.

Influence of electromagnetic radiation on the degradation of reinforced concrete structures – Review

Industrial land civil buildings made of reinforced concrete are increasingly exposed to ambient electromagnetic radiation. The study of the influence of electromagnetic radiation on reinforced concrete structures is becoming increasingly important.This article is devoted to the influence of the electromagnetic field as a hazard factor on the degradation of reinforced concrete structures. The paper gives a classification of electromagnetic radiation and identifies two main types of radiation: ionizing and non-ionizing. The main changes that occur in the structure of reinforced concrete structures under the influence of ionizing radiation, leading to a loss of strength of structures up to 60 %, are described. The influence of non-ionizing radiation is dangerous for reinforced concrete structures with prolonged exposure. This effect is manifested in the fact that in the presence of water in the pores and capillaries, the corrosion rate of metal reinforcement in reinforced concrete increases significantly. In this regard, it is necessary to conduct further research on the influence of the length, frequency and energy of electromagnetic radiation on the degradation processes of the reinforced concrete structures surrounding us. Therefore, it is necessary to develop scientific methods and ways to protect reinforced concrete structures from electromagnetic radiation of various frequencies.

Investigation of the influence of electromagnetic radiation on the operation of electronic metering devices for electricity is one of the demanded areas of forensic electrical engineering expertise. However, the scientific and practical study of this area of forensic research does not coincide with modern requirements. The study of the influence of electromagnetic radiation of the radio frequency range on the operation of electronic metering devices for electricity, as well as the identification of such radiation as accidental or intentionally created for the purpose of unaccounted consumption of electricity, are relevant. The article systematizes the requirements established by regulatory documents for the stability of the operation of metering devices for electricity when exposed to radiofrequency electromagnetic radiation.

Investigation of Powerful Electromagnetic Radiation Influence on Receiving Antenna Systems with Superconducting Protective Devices

This work is devoted to the problem of the effect of a powerful ultra-short duration electromagnetic radiation on the superconducting protection device as a load of antenna-feeder circuit of radioelectronic systems. The above device is used in the monitoring systems of the land surface to the benefit of agriculture, geodesy, mapping, monitoring of land and ocean surfaces, and, also, the atmospheric layers, remote control systems in engineering and industry related branches. This goal was achieved by substantiation of the approach to the description of the arbitrary antenna response to the electromagnetic radiation, using the antenna system frequency response. The most significant result is the offered approach to the relationship determination between the response of the arbitrary antenna to the radiation influence and its characteristics in a radiation mode. The sought relationship determination showed that, such characteristics of the antenna systems are the antenna input impedance and the complex normalized radiation pattern in the radiation mode at an arbitrary frequency. The significance of the results is in obtainment of the analytical relations to estimate the effect of the radiation under consideration on the device that is in superconducting, mixed and normal phase states. The peculiarity of the obtained results makes it possible to consider the antenna system coordination degree of the protection device based on superconducting thin film. Conversion of the radiation energy into the induced currents’ energy that is the basis for selection and structural calculation of protection devices of the radio electronic facilities against powerful electromagnetic radiation build upon microstrip transmission lines.

Multistable dynamics in a Hopfield neural network under electromagnetic radiation and dual bias currents

This paper investigates a Hopfield neural network under the simulation of external electromagnetic radiation and dual bias currents, in which the fluctuation of magnetic flux across the neuron membrane is used to emulate the influence of electromagnetic radiation. Utilizing conventional analytical methods, the basic properties of the proposed Hopfield neural network are discussed. Due to the addition of electromagnetic radiation and dual bias currents, the Hopfield neural network shows high sensitivity to system parameters and initial conditions. The proposed Hopfield neural network possesses multistability with periodic attractor, quasi-periodic attractor, chaotic attractor and transient chaotic attractor, and all of the attractors are hidden attractors because there is no equilibrium point in the system. In particular, when the neuron membrane magnetic flux is different, the system can present transient chaos with different chaotic times. More interestingly, with the change of system parameters, the proposed Hopfield neural network can exhibit parallel bifurcation behaviors. Finally, the Multisim simulation and hardware experiment results based on discrete electronic components are conducted to support the numerical ones. These results could give useful information to the study of nonlinear dynamic characteristics of the Hopfield neural network.

NiMnO3 Anchored on Reduced Graphene Oxide Nanosheets: A New High-Performance Microwave Absorbing Material.

With the increasing influence of electromagnetic radiation on precision instruments and organisms, there is an urgent need for research on lightweight and high-strength electromagnetic wave absorbing materials. This study has probed into a new composite absorbing material based on reduced graphene oxide (rGO)-NiMnO3, where the like-core-shell NiMnO3 is anchored on the rGO nanosheets to significantly improve the electromagnetic wave dissipation ability of the composite material using the inter-component dipole polarization and interface polarization. At the same time, NiMnO3 can effectively adjust the impedance matching ratio of rGO so that electromagnetic waves can effectively enter the absorbing material. At a thickness of 3.73 mm, the maximum absorption strength of rGO-NiMnO3 reaches −61.4 dB at 6.6 GHz; at a thickness of 2.5 mm, the adequate absorption bandwidth is 10.04–18.00 GHz, achieving a full coverage for the Ku band. As a new option for preparing lightweight and broadband electromagnetic wave absorbing materials, rGO-NiMnO3 is an ideal material for electromagnetic wave protection.
