Microchannel plate (MCP) photomultiplier tubes (PMTs) are frequently used in experimental diagnostics, where they are operated in single-pulse current measurement mode. However, considering the significant amplitude fluctuations in the measured signal, the resulting output signal from the MCP-PMT is inevitably distorted by gain saturation. Therefore, understanding the correlation between the MCP-PMT output signal and gain saturation is critical in assessing the extent of output signal distortion and determining the MCP-PMT saturation level. This knowledge allows for a more precise assessment of the input signal's features. In this paper, we present an experimental method for restoring the initial waveform from the saturated MCP-PMT signal. To correct the amplitude-drop caused by gain saturation, our technique involves calibrating the MCP-PMT's relative gain as a function of the accumulated output charge using a square-wave light source. We then applied this approach to restore a ∼500 ns saturated pulse from a double-layer 10 mm diameter MCP-PMT. The restored signal showed a deviation of less than 6% from the reference waveform, which validates the effectiveness of the technique.
Scalable generalized screening for high-order terms in the many-body expansion: Algorithm, open-source implementation, and demonstration
Authors: Broderick Dustin R. , Herbert John M. 
Published: November 2023

The many-body expansion lies at the heart of numerous fragment-based methods that are intended to sidestep the nonlinear scaling of ab initio quantum chemistry, making electronic structure calculations feasible in large systems. In principle, inclusion of higher-order n-body terms ought to improve the accuracy in a controllable way, but unfavorable combinatorics often defeats this in practice and applications with n ≥ 4 are rare. Here, we outline an algorithm to overcome this combinatorial bottleneck, based on a bottom-up approach to energy-based screening. This is implemented within a new open-source software application (“Fragme∩t”), which is integrated with a lightweight semi-empirical method that is used to cull subsystems, attenuating the combinatorial growth of higher-order terms in the graph that is used to manage the calculations. This facilitates applications of unprecedented size, and we report four-body calculations in (H2O)64 clusters that afford relative energies within 0.1 kcal/mol/monomer of the supersystem result using less than 10% of the unique subsystems. We also report n-body calculations in (H2O)20 clusters up to n = 8, at which point the expansion terminates naturally due to screening. These are the largest n-body calculations reported to date using ab initio electronic structure theory, and they confirm that high-order n-body terms are mostly artifacts of basis-set superposition error.
Hyperdialectisms revisited
Authors: Doreleijers Kristel , Swanenberg Jos 
Published: November 2023

Abstract
Ongoing processes of dialect leveling and loss have given rise to the widespread use of the concept of
hyperdialectism in sociolinguistic research. Hyperdialectisms are considered to be a reaction to dialect loss: a typical dialect
feature that is distinctive from the standard language or a neighboring dialect is overgeneralized. However, there is pitfall in
using the concept as an umbrella term for all deviating dialect forms. In this paper, we aim to provide a revisited view of
hyperdialectisms based on written dialect sources. In doing so, we use hyperdialectal adnominal gender marking in southern Dutch
Brabantish dialects as a case study. We show that unexpected forms were already present in early twentieth-century dialect use,
despite dialect grammar descriptions from the second half of the century often being used as a point of reference for ‘correct’
grammar. Furthermore, we argue that the concept of hyperdialectism requires careful layering in sociolinguistic analysis.
A sightseeing diminutive tour in Limburgian
Authors: Jacobs Haike 
Published: November 2023

Abstract
This paper provides an overview, based on the MAND database and on additional recordings for Limburgian Panningen, of diminutive formation in Limburgian and focuses on the status of n-assimilation. It is shown that both the presence and the absence of n-assimilaton poses problems both for existing phonological descriptions as well as for constraint-based approaches to phonology such as standard Optimality Theory. We will show that the nature of the three interacting modifications, that is n-assimilation, k-fronting and s-insertion is different. k-fronting and s-insertion are limited in their application to the diminutive suffix and are as such lexical modifications. n-assimilation is shown to apply also across word boundaries and is a post-lexical modification. This allows for a straightforward description in stratal OT and for a better understanding of the data observed.
Are there different kinds of appositive relative clauses?
Authors: de Vries Mark 
Published: November 2023

Abstract
In his latest book on relative clauses, Cinque claims that there are two fundamentally different kinds of
appositive (non-restrictive) relative clauses. The unintegrated ones are the typical English type, the integrated ones are found
in various languages, including Chinese and Japanese. This second type shares some characteristics with restrictive relatives, and
seems to require a different syntactic analysis. Some languages, like Italian, supposedly have both types. A list of a dozen
criteria differentiates the two, such as the use of relative pronouns and the possibility of heavy pied piping. However, when we
carefully look at Dutch and other languages, the picture starts to blur considerably, and an abundance of (micro)variation shows
up. This is problematic. I argue that the suggested criteria do not add up to two natural classes at all and are in fact
non-explanatory. Therefore, we need to focus on what is truly fundamental to non-restrictiveness, which leads to a different
perspective on the matter.
Teaching listening for interpreting through mind mapping
Authors: Li Xiangdong 
Published: November 2023

Abstract
Interpreting scholars claim that mind mapping can be used pedagogically to enhance trainees’ interpreting-specific listening skills. However, so far relevant empirical studies have been rare. A single-group post and retrospective self-assessment design was used to examine student interpreters’ attitudes towards the use of mind mapping in teaching listening for interpreting and its effectiveness. Eighty-two students were involved as participants. An instruction experience questionnaire was administered at the end of the pedagogical intervention to examine their attitudes towards the mind mapping exercise. Two self-assessments of knowledge and skills were conducted at the end of the pedagogical intervention to investigate their pre-test post-test gains. One was a retrospective self-assessment about their competence before the exercise (then self-assessment) and the other was a post self-assessment about their competence after the exercise (now self-assessment). The results indicate that the participants perceived mind mapping as a positive learning experience and that it was effective in developing students’ interpreting-specific listening knowledge and skills.
Design and analysis of a group-III nitride superlattice structure based semiconductor laser diode for blue region emission
Authors: Sireesha Uppala , Gupta Nikhil Deep 
Published: November 2023

Abstract
The demand for high-power blue laser diodes (LDs) in the range above 2 W has been steadily increasing due to their applications in solid-state lighting, projection displays, high-density optical data storage and underwater communication. However, current designs face limitations in terms of achieving both high power output and efficiency. This work focuses on the design, development and numerical analysis of a blue LD utilizing group-III nitride superlattice structures. The present study aims to overcome design challenges by investigating the fundamental factors affecting the performance of blue LDs based on superlattice InGaN structures through careful device parameter optimization. The results show that our device successfully emits at around 430 nm wavelength and is capable of achieving a differential quantum efficiency of 46.91%, with a maximal optical power output of 2.18 W for 1.71 A of current for a strip width of 15 µm. However, when the strip width is increased to 20 µm, 4.6 W optical power is achieved with 3 A of injection current. Numerical studies are performed with several calibrated physics models and finite-difference time-domain techniques. Our results provide an insight into the potential of using superlattice group-III nitride structures to enhance the performance of blue LDs, opening up new possibilities for high-power and high-efficiency devices in the future.

Published: November 2023

Abstract
The main aim of this paper is to investigate the different types of soliton molecule solutions of the second extend (3+1)-dimensional Jimbo-Miwa equation in a fluid. Four different localized waves: line solitons, breather waves, lump solutions and resonance Y-type solutions are obtained by the Hirota bilinear method directly. Furthermore, the molecule solutions consisting of only line waves, breathers or lump waves are generated by combining velocity resonance condition and long wave limit method. Also, the molecule solutions such as line-breather molecule, lump-line molecule, lump-breather molecule, etc. consisting of different waves are derived. Meanwhile, higher-order molecule solutions composed of only line waves are acquired.

Authors: Ma Zhenyang , Li Mufan 
Published: November 2023

Abstract
The electromagnetic environment of low-altitude airspace has become extremely complex due to the rapid advancement of radio technology. In particular, the electromagnetic energy of HIRF (High Intensity Radiation Field) that is frequently emitted by radar, radio stations, radios, and various ships/airborne impacts negatively aircraft flight safety. In this paper, based on the modeling of a consumer UAV, the HIRF effect is simulated using UWB-HPM, and the electric field variation law at key position and antenna coupling law of the UAV under plane wave irradiation in different directions are analyzed with the help of CST simulation software. The results show that for front-door coupling, the shorter the pulse width of the interference signal is, the stronger the interference for the antenna is, while for back-door coupling, irritation direction and pulse width play a significant role in the coupling effect.

Published: November 2023

Abstract
In this work, an InGaAs/InAlAs dopingless tunnel field-effect transistor is designed and systematically examined through numerical simulations. In line with the charge plasma concept, the proposed device can not only create a p-n-i-n structure without doping to enhance electron tunneling but also effectively overcome issues caused by doping such as random doping fluctuation, high thermal budget, etc. By investigating the effects of the HfO2 length (L
H), the source-side channel length (L
sc), and the source-drain electrodes structure on the proposed device, it concludes that the best device characteristic can be acquired when L
H is located between 110 nm and 128 nm, L
sc=4 nm, and double source-drain electrodes are adopted.
Study on optical absorption of silicene nanodisks under strain modulation
Authors: Chen Feng , Qi Fenghua , Jin Guojun 
Published: November 2023

Abstract
Using the tight-binding Hamiltonian approach, we theoretically study the position of energy level structures and optical absorption peaks by applying stress forces laterally or longitudinally of triangular zigzag silicene nanodisks (TZSN). We consider the effect of strain on the structure. We found that by applying a lateral force similar to that applied to the stretched structure (the force applied to the compressed structure), all absorption peaks can be observed to move to the left or to the right as a whole in the optical absorption spectrum, and this shift is more pronounced at the main absorption peaks, indicating the possibility of TZSN as a strain sensor, and we also considered which size of TZSN would be more suitable as a sensor. On the other hand, it is found that the compressive strain can effectively reduce the light absorption intensity when the incident energy is less than 1.4 eV (0.89 µm). The work described in the system can be used as new material is applied to the sensor and imaging equipment, etc.

Published: November 2023

Abstract
In order to study the tolerance threshold and damage process of radar receiving front end against high power microwave pulse attack, the relationship between the damage of receiving front end and injected signal power, pulse width, and duration was obtained by injection test. The experimental results show that the damage of PIN limiter by high power microwave is a slow worsening process near the damage threshold. Based on the test results, the radar withstanding range of high-power microwave weapon attack is calculated theoretically, which can provide theoretical support for the radar receiving front-end design.

Published: November 2023

Abstract
The high efficiency of the saturation state and rollback state is an important part of the front end of modern wireless communication systems. Improving the efficiency of RF power amplifiers is of great significance for energy saving and amplifier performance. Based on the traditional Doherty power amplifier, the harmonic suppression network is introduced before the fundamental frequency matching, so that the second harmonic impedance and third harmonic impedance can achieve continuous class F impedance matching conditions, and then the saturation efficiency and regression efficiency can be improved without affecting the fundamental wave matching. The results of the simulation show that the saturation efficiency of the Doherty amplifier reaches 73.94%~77.22%. The drain efficiency of back-off 6 dB reaches 61.80%~62.92%. The average saturation drain efficiency is 75.58%, and the average back-off 6 dB drain efficiency is 62.36%.

Published: November 2023

Abstract
Saline soils make up almost 25% of the entire earth’s surface. Their areas, unfortunately, have a steady tendency to expand due to the aridization of the climate and the global increase in the average annual air temperature of the planet. The increased concentration of salts in the soil limits the diversity of cultural and conditions the poverty of natural flora, forms areas of risky agriculture in the south of Ukraine. Seeds are a unique product of evolution, the main generative organ of plants, characterized by a number of morphological, physiological and biological features, among which there is adaptation heterogeneity. It is established that by the number of germination days (the seeds of the cultural flora sprouts for 7–10 days, and in wild representatives this indicator extends to 10–12 days) the plants can be arranged in the following order: seven days –Secale cereale L., Triticum durum L., Avena sativa L., Hordeum vulgare L., Helianthus annuus L., Matricaria recutita L.; ten days – Beta vulgaris L., Phaseolus vulgaris L. and twelve days – Valeriana officinalis L. It is found that the most optimal for germination is the aquatic environment, so the plants are arranged according to the list: Helianthus annuus L. → Avena sativa L. → Triticum durum L. → Matricaria recutita L. → Secale cereale L. → Hordeum vulgare L. → Beta vulgaris L. → Valeriana officinalis L. → Phaseolus vulgaris L. It is proved that Na+ and Cl–ions differentially affect the seed germination energy: at a concentration of 0.1% NaCl – Triticum durum L. → Helianthus annuus L. → Hordeum vulgare L. → Secale cereale L. → Phaseolus vulgaris L. → Avena sativa L. → Matricaria recutita L. → Beta vulgaris L. → Valeriana officinalis L.; at a solution concentration of 0.2% NaCl – Secale cereale L. → Triticum durum L. → Helianthus annuus L. → Avena sativa L. → Matricaria recutita L. → Hordeum vulgare L. → Phaseolus vulgaris L. → Valeriana officinalis L. → Beta vulgaris L. The results obtained indicate that the chloride load in the seeds of plants manifests itself in the form of distress as well as eustress. It has been proved that the diagnostic features of chloride hermesis were more clearly manifested in the representatives of the cultural flora than the natural ones.

Authors: Saukh S Ye 
Published: November 2023

Abstract
The intervals for determining the variables in the standard MILP-formulation of the UC-problem are analyzed. The need to take into account the state and load values in the pre-forecast and post-forecast time has been established. The suitability of the standard MILP-formulation of the UC-problem, problem with initial conditions, for solving dispatch control problems and the unsuitability of such a formulation for solving the generation capacity planning problems is shown. The standard MILP-formulation of the UC-problem on the cyclical forecasting interval is proposed. The suitability of the proposed MILP-formulation of the UC-problem for its application in the problem of planning the development of the generation capacity of power systems with a large share of RES is shown.

Numerical simulation of the surface subsidence evolution caused by the flooding of the longwall goaf during excavation of thin coal seams
Authors: Sakhno I , Sakhno S , Petrenko A , Barkova O , Kobylianskyi B 
Published: November 2023

Abstract
Underground mining has a significant influence on ground movement, which induces serious environmental disturbances on land. Movements of the rock strata can be the cause of changes in the hydrogeological regimes of groundwater. As a result, the risk of flooding of the longwalls goaf increases. The specific phenomenon of the Ukrainian Donbas is the flooding of the underground roadway system at the result of the closure of the mines. Water saturation of rocks leads to a decrease in its strength. The result is repeated subsidence. The activation of the ground movement processes over the longwall goaf due to their flooding has not been studied enough. In this paper, for the geological conditions of thin coal seams typical for the Ukrainian Donbas, ground movement evolution caused by flooding of longwalls goaf was studied. Ansys code was used to analyze the evolution of surface displacement in different hydrogeological conditions. As a result of numerical simulation, it was found that full flooding of the longwall goaf leads to an increase in surface subsidence by 22.4%, while the length of the trough increase by 1.3%. Maximal inclination increases by 34.4%, and maximal curvature – by 74%. This contributes to a significant increase in hazards for surface infrastructure located on the edges of the subsidence trough. The control of the negative impact on surface infrastructure objects, water and agro-industrial objects can be ensured by a timely prediction of ground movement and the implementation of surface controlling methods to prevent critical surface deformations.
Engineering method for predicting the displacement of the earth’s surface under the influence of stope workings of coal mines

Published: November 2023

Abstract
The development of a sufficiently reliable forecast of the values of trough parameters on the earth’s surface and the displacement of undermined rocks using mathematical modeling methods is an urgent problem for mining. Not only the protection of objects on the earth’s surface depends on its successful solution, but also the choice of the location of mine workings and rational ways to protect them from the influence of rock pressure, the forecast of gas release from undermined sources, the occurrence of gas-dynamic phenomena, the rationale for rational ventilation schemes for excavation areas, the calculation of the bearing capacity supports and many other engineering tasks. The study is based on the use of experimental data obtained during the operation of a separate extraction area, respectively, at the first stage when the working face is removed from the split furnace and at the second stage above the working face when it is sufficiently removed from the open working. This makes it possible to obtain all the necessary experimental data for constructing a general scheme for the development of clearing operations and the formation of a trough for the displacement of the earth’s surface in two stages. On the basis of the studies carried out, it was found that the maximum subsidence of the earth’s surface above the cut working with a sufficient distance from the production face is equal to the subsidence above the production face at the stage of attenuation of the processes of displacement of undermined rocks and the earth’s surface. This gives grounds to make an assumption about the closeness of the displacement parameters of the stationary and dynamic semitroughs.
