Favored one proton radioactivity within a one-parameter model*
Authors: Zou You-Tian , Pan Xiao , Li Xiao-Hua , Wu Xi-Jun , He Biao 
Published: July 2022

Abstract
In the present work, a phenomenological one-parameter model (OPM) based on the Wentzel-Kramers-Brillouin (WKB) theory is applied to study the favored one proton radioactivity (the orbital angular momentum l taken away by the emitted proton is equal to zero) half-lives. The calculated results can reproduce the experimental data well within a factor of ∼3. In addition, we extend the OPM to predict the half-lives of possible favored one proton radioactivity nuclei whose decay is energetically allowed or observed but not quantified in NUBASE2020. For comparison, a universal decay law of one proton radioactivity (UDLP) is also used. It is obviously found that our predicted results are close to the ones using UDLP. The predictions are helpful for searching for the new nuclides with favored one proton radioactivity.
Impact of reputation-based switching strategy between punishment and social exclusion on the evolution of cooperation in the spatial public goods game
Authors: Quan Ji , Guo Huiting , Wang Xianjia 
Published: July 2022

Abstract
The historical behavior of a defector in a group is usually considered in the determination of the intensity of the punishment to be applied to the defector. Because exclusion is a more severe form of punishment, we introduce a conditional punishment that allows punishers to choose between traditional punishment and exclusion. The specific form of punishment is chosen to fit the specific reputation of the defector. A good reputation garners a traditional milder punishment, such as a fine, whereas a bad reputation merits exclusion. The historical behaviors of the individuals in a group are recorded to evaluate their reputations. Those whose reputations fall below a designated threshold are regarded as bad. We study the effects of reputation thresholds, fines, enhancement factors, and exclusion costs on the evolution of cooperation in spatial public goods games. Simulations show that higher thresholds are more conducive to the evolution of cooperation. An extremely small enhancement factor can induce individuals to cooperate when the threshold is relatively high. Cooperation also appears with smaller enhancement factors for higher fines or lower exclusion costs. These results may expand our understanding of how these two strategies of punishment promote cooperation.

Published: July 2022

Abstract
The principle of industrial machine monitoring and vehicle camera transmission system are focusing on this paper. Video compression is widely used in many industrial applications like continuous monitoring of machines which consumes more storage by capturing every motion detection in machine, hence video coding is highly recommended for video compression without any loss in the actual video. By using wavelet transform delivers the superior localization both in frequency and time domain and its results showcases the better performance while comparing with discrete cosine transform. A comparative analysis has been carried on Video compression using Haar and orthogonal (Daubechies) wavelet. Duplicate coefficients of discrete wavelet transform is reduced by using quantization technique. It aims to attain minimum error while preserving the high peak signal to noise ratio and image quality in the acceptable range. Using PSNR as measure of quality, this paper shows that Daubechies wavelet provides the better quality of video compared to Haar wavelet. Evaluation of performance is depends upon on compression ratio, PSNR, MSE, and SSIM.

Published: July 2022

Abstract
Deposition of boron-containing coatings is determined by their promising use for surface modification goals. In this work, we consider the equipment for the implementation of two plasma methods for the deposition of thin films of pure boron on the surface. These are a magnetron sputtering with a crystalline boron target heated in the discharge, and a system of an evaporation of pure boron target by an electron beam generated using forevacuum plasma source. The features of functioning, and operating parameters of these devices are presented. The deposition rate of boron coatings on the samples was about 20 nm/min for magnetron sputtering. The boron film deposition rate was significantly higher and reached 1 µm / min.

LArQL: a phenomenological model for treating light and charge generation in liquid argon
Authors: Marinho F. , Paulucci L. , Totani D. , Cavanna F. 
Published: July 2022

Abstract
Experimental data shows that both ionization charge and scintillation light in LAr depend on the deposited energy density (dE/dx) and electric field (

E

). Moreover, free ionization charge and scintillation light are anticorrelated, complementary at a given (dE/dx,

E

) pair. We present LArQL, a phenomenological model that provides the anticorrelation between light and charge and its dependence on the deposited energy as well as on the electric field applied. It modifies the Birks’ charge model considering the contribution from the escape electrons at null and low electric fields, and reconciles with Birks’ model prediction at higher fields. Deviations from current Birks’ model are observed for LArTPCs operating at low

E

and for heavily ionizing particles. The LArQL model presents a satisfactory description at dE/dx and field ranges for interacting particles in LArTPCs and fits well the available data. Improvements via data sets compilation and “global” fits are also interesting features of the model.

Published: July 2022

Abstract
With the increasing application of nuclear technology in many fields, in order to meet the requirements for the measurement range of nuclear radiation dose rate in different fields, a new X/γ dose rate measurement method is proposed in this paper. Using MPPC to couple CsI(TI) scintillator, combined with continuous periodic charges integration electronics, a detector system was developed. It enables MPPC to work in two different regions, avalanche and proportional, and realizes a wide range of dose rate measurement through gain changes between different regions. In experiments, this method measured the γ radiation dose rate in radiation fields between 0.1 μGy/h to
400 Gy/h
60Co. Additionally, it measured an energy resolution for 137Cs at 9.4% at a dose rate of 1 mGy/h. These results demonstrate that this method is both accurate and feasible.

Abstract
Metropolis’ contribution (anthropogenic aerosols) to solar dimming and brightening remains a hot topic of special concern over the past several decades. However, urbanization effects on surface incident solar radiation (R
s) have not been comprehensively investigated. In this study, the urbanization effects on solar dimming and brightening were addressed using the densely distributed reconstructed R
s data at 375 stations and 92 urban–rural station pairs over the time period of 1960–2019 in China. The results indicate that the impacts of urbanization on the monthly mean R
s is 0.86 ± 7.99 W m−2 during the study period, while the impact is 0.90 ± 8.30 W m−2 and 0.82 ± 8.26 W m−2 for the solar dimming (1960–1992) and brightening (1992–2019) phase, respectively. The urbanization effects on the trend of R
s is −0.39 and 0.16 W m−2 per decade during dimming and brightening, respectively. It also found that urbanization effects on R
s trend differs strikingly in magnitudes for specific regions in China. Generally, urbanization speeds up China’s dimming in the dimming phase and slows down China’s brightening in the brightening phase.

Published: July 2022

Abstract
The field of movement ecology has seen a rapid increase in high-resolution data in recent years, leading to the development of numerous statistical and numerical methods to analyse relocation trajectories. Data are often collected at the level of the individual and for long periods that may encompass a range of behaviours. Here, we use the power spectral density (PSD) to characterise the random movement patterns of a black-winged kite (Elanus caeruleus) and a white stork (Ciconia ciconia). The tracks are first segmented and clustered into different behaviours (movement modes), and for each mode we measure the PSD and the ageing properties of the process. For the foraging kite we find 1/f noise, previously reported in ecological systems mainly in the context of population dynamics, but not for movement data. We further suggest plausible models for each of the behavioural modes by comparing both the measured PSD exponents and the distribution of the single-trajectory PSD to known theoretical results and simulations.
First-passage times of multiple diffusing particles with reversible target-binding kinetics
Authors: Grebenkov Denis S , Kumar Aanjaneya 
Published: July 2022

Abstract
We investigate a class of diffusion-controlled reactions that are initiated at the time instance when a prescribed number K among N particles independently diffusing in a solvent are simultaneously bound to a target region. In the irreversible target-binding setting, the particles that bind to the target stay there forever, and the reaction time is the Kth fastest first-passage time to the target, whose distribution is well-known. In turn, reversible binding, which is common for most applications, renders theoretical analysis much more challenging and drastically changes the distribution of reaction times. We develop a renewal-based approach to derive an approximate solution for the probability density of the reaction time. This approximation turns out to be remarkably accurate for a broad range of parameters. We also analyze the dependence of the mean reaction time or, equivalently, the inverse reaction rate, on the main parameters such as K, N, and binding/unbinding constants. Some biophysical applications and further perspectives are briefly discussed.
Iron ore underground mining under the internal overburden dump at the PJSC “Northern GZK”
Authors: Pysmennyi S , Chukharev S , Kyelgyenbai K , Mutambo V , Matsui A 
Published: July 2022

Abstract
Deterioration of mining conditions at mining deposits by open pit methods (increased mining depths, reduced ore deposit thickness) leads to an increase in mining costs. In Ukraine, to reduce open pit mining costs, overburden is disposed in temporary internal dumps located directly in the open pit over the ore reserves. Reactivation of pit areas with the temporary internal overburden dump located on them results in a surge of mining operations and deterioration of technical and economic indicators. Increased energy consumption, a decrease in working site parameters, an increase in angles of open pit slopes and stripping lags lead to unprofitability of open pit mining. One of the solutions to the mentioned scientific and engineering problem involves combined mining of deposits by integrated open pit and underground mining operations. The combined open pit-underground mining method enables reducing mining costs and enhancing technical and economic indicators. The suggested schemes for opening reserves located under the internal overburden dump enhance technical and economic indicators of deposit mining through making the internal dump a permanent one. This allows further disposal of overburden into internal dumps. Implementation of scientific recommendations and technological solutions resulted from the research performed (exemplified by the deposit Hannivske, Ukraine) reduces the cost of ore by 1.33 USD/t. At the same time, the total cost of building an underground mine makes 16.4 M USD, which is 30% less than when applying traditional opening vertical shaft schemes.

Published: July 2022

Abstract
The article presents basic information about the method of hydromechanical extraction of amber from amber-containing rocks, water-sludge scheme and classification scheme. The constructive scheme of the vibroclassifier is also presented, which is based on the principle of using the influence – vibration and bubbling of the suspension by air bubbles. Studies of the separation process and distribution of fractions in multidisperse liquid on a vibroclassifier of complex action were performed. The obtained theoretical and graphical dependences allowed to establish changes in the parameters of the velocity of sand and amber particles in the bath of the vibroclassifier on the size of fractions and density of the suspension, focusing on the size of amber up to 5mm. At the same time, the problem of determining the dependence of the transition coefficient from the rate of free to the rate of compressed deposition on the density of the suspension and the size of the fractions was solved. Dependencies have been established that have a theoretical justification for the physical process and that describe the experimental data on the Rayleigh curve.

Published: July 2022

Abstract
The article is devoted to the study of Kryvbas – a unique landfill for understanding the structure of landscapes. In the history of studying the nature and landscapes of Kryvbas, the authors have identified two main stages: initial knowledge (ancient times – the first half of the XIX century) the second half of the XIX – beginning of the XXI century), which gave the opportunity for 130 years to form one of the largest not only in Ukraine but also in the world landscape and technical system. The formation of this original landscape-technical system is due to three factors: a) detailed studies of the nature and landscapes of Kryvyi Rih region, b) the richness and diversity of natural resources of the region, c) intensive development. The authors paid special attention to the functional-genetic classification of anthropogenic landscapes of Kryvbas, their characteristics and mapping. The authors note that among the industrial ones, special attention should be paid to mining and industrial landscapes, in particular dumps, which are the most suitable landscape complexes not only for reclamation works, but also for cultivating the entire landscape and technical system of Kryvbas.
Drainage reconstruction in the zone of excessive moisture during the cultivation of blueberries on poorly water-permeable clay soils

Published: July 2022

Abstract
To ensure efficient agricultural production in the humid regions of Ukraine, drainage of wetlands is one of the first places. The area of drained lands is make up to 9.7% of the total arable lands in Ukraine. In 1990, 1,976.500 hectares were used in active agricultural production, and the share of arable land on drained lands was 70.7%. Of the more than 1130 drainage systems with an area of more than 2.2 million hectares only 37% were built between 1980 and 1990, i.e. younger than 35 years. The remaining 63% of systems have been built and operated for more than 35 years. Since the 1990s, the construction of new and modernization of existing drainage systems in Ukraine has been almost non-existent. Maintenance of the systems was significantly reduced, which led to a significant deterioration in their technical condition, a change in the water regime of soils and the development of degradation processes. Traditionally, in Ukraine, a significant (1.4 million hectares) area is drained with ceramic drainage. We show the experience of reconstruction of the drainage system, which is located in the Pre-Carpathian Upland region of the Ukrainian Carpathians, the Middle Carpathian terrace plain, where a Drainage of Clay Pipes was built more than 35 years ago. The results of the analysis of the reasons of unsatisfactory drainage operation, identification of the most critical zones with the use of field research and earth remote sensing data are presented. To eliminate local wetlands, plastic drainage with a diameter of 50 mm is proposed. To increase the efficiency of its work on heavy clay soils with a filtration coefficient less than 0.01, the backfilling of the trench with local material – gravel with a fraction of 5 ... 25 mm with geotextile protection. During the construction of the new drainage, ceramic drains of the previously constructed drainage were found. They were cleaned mechanically and connected through a filter backfill to the newly built drains.
