Remarks on gapless relative clauses and complement clauses in Mandarin Chinese
Authors: Pan Haihua 
Published: July 2022

Abstract
This paper makes remarks on the syntactic status of Gapless Relative Clauses (GRCs) in Mandarin Chinese and shows
that the arguments for their complement status are not supported by the facts in Mandarin Chinese, as almost all the arguments for
the complement clause analysis of GRCs, as presented in Huang (2016), could be argued
to be evidence for the relative clause (RC) analysis of GRCs. The following RC recoverability hierarchy, Argument RC > Adjunct
RC > GRC, is proposed to explain the contrasts discussed in Huang (2016) and this
paper, and the relevant facts and differences could be accounted for if one assumes that the RCs further to the right in the
hierarchy above are more difficult to be recovered than the RCs further to the left in the above hierarchy and should thus occur
closer to the head noun. This paper demonstrates that GRCs are really RCs licensed by a covert semantic variable, and suggests
that the gapless requirement on complement clauses be replaced by the following two conditions: (a) no syntactic gap or semantic
variable exists in the relevant clause that is related to the head noun in question and (b) a semantic condition, to be specified
in this paper, is necessary on the relationship between the clause in question and the modified head noun.
Is it possible to prove the Altaic theory on the basis of negative forms in Mongolian, Manchu and Turkish?
Authors: Dolińska Joanna 
Published: July 2022

AbstractThe research question posed in this article is whether the Altaic theory is possible, if it is discussed on the basis of chosen negative forms in Mongolian, Turkish, Manchu and its Sibe dialect. The supporters of the Altaic theory assume that these languages (and some include Japanese, Korean and Ainu to this list (Miller, 1967)) emerged from the same root. The opponents of this theory think that the similarities in these languages have resulted from historical contacts between their speakers (Doerfer, 1966, p.122). This article consists of the analysis of negative forms in various stages of Mongolian, Manchu and Turkish languages carried out on the basis of literary monuments and contemporary resources. The conclusions concerning the possibility of the Altaic theory based on the described negative forms have been presented at the end, accompanied by the Index of negative particles and suffixes.
Imaging of PbWO4 crystals for G experiment test masses using a laser interferometer
Authors: Assumin-Gyimah K T A , Holt M G , Dutta D , Snow W M 
Published: July 2022

Abstract
It is highly desirable for future measurements of Newton’s gravitational constant G to use test/source masses that allow nondestructive, quantitative internal density gradient measurements. High density optically transparent materials are ideally suited for this purpose since their density gradient can be measured with laser interferometry, and they allow in-situ optical metrology methods for the critical distance measurements often needed in a G apparatus. We present an upper bound on possible internal density gradients in lead tungstate (PbWO4) crystals determined using a laser interferometer. We placed an upper bound on the fractional atomic density gradient in two PbWO4 test crystals of

cm−1. This value is more than two orders of magnitude smaller than what is required for G measurements. They are also consistent with but more sensitive than a recently reported measurements of the same samples, using neutron interferometry. These results indicate that PbWO4 crystals are well suited to be used as test masses in G experiments. Future measurements of internal density gradients of test masses used for measurements of G can now be conducted non-destructively for a wide range of possible test masses.
Understanding the nature of students’ experience of pre-university practical work in physics
Authors: Dunnett K 
Published: July 2022

Abstract
Introductory practical work in university physics degrees is dominated by highly constrained and instructions-based tasks with limited value for developing students’ scientific and critical thinking skills. One possible explanation for this may be the assumptions made about new students’ prior experiences. Over the course of 5 years, approximately 800 first year physics students completed a simple survey of the nature of their prior experiences of physics practical work. An informative means of presenting the data and understanding their experiences as either passive or practical, or in terms of their freedom to make decisions, is developed. Most new undergraduate students have some experience of decision making in relation to physics practical work, which should be incorporated into course design. The data also indicates that different education systems provide different opportunities for decision making, illustrating the need to align practical training at a local level.
DFT insights into the selective NH3 sensing mechanism of two dimensional ZnTe monolayer
Authors: Chang Xiao , Li Xiaofang , Xue Qingzhong 
Published: July 2022

Abstract
Exploring novel NH3 sensing materials is crucial in chemical industries, fertilizing plants and medical fields. Herein, for the first time, the NH3 sensing behaviors and sensing mechanisms of two dimensional (2D) ZnTe monolayer are systematically investigated by density functional theory calculations. It is shown that 2D ZnTe monolayer exhibits excellent selective NH3 sensing properties. (220) crystal facet of ZnTe possesses a higher NH3 adsorption energy (−1.59 eV) and a larger charge transfer (0.195e) than (111) and (311) crystal facets. The positive charges could enhance NH3 sensing while the negative charges could reduce NH3 sensing. The NH3 adsorption strengths are significantly improved in O2 atmosphere while it is negligibly affected by N2 atmosphere and H2O atmosphere. Moreover, the presence of Zn vacancy and Fe, Co, Ni doping could improve the NH3 sensing of ZnTe. Additionally, the experimental results confirms that ZnTe possesses a low detection limit of 0.1 ppm NH3. These theoretical predictions and experimental results present a wide range of possibilities for the further development of ZnTe monolayer in NH3 sensing fields.
Elastometry of clot phantoms via magnetomotive ultrasound-based resonant acoustic spectroscopy
Authors: Levy Benjamin E , Oldenburg Amy L 
Published: July 2022

Abstract

Objective. An ultrasound-based system capable of both imaging thrombi against a dark field and performing quantitative elastometry could allow for fast and cost-effective thrombosis diagnosis, staging, and treatment monitoring. This study investigates a contrast-enhanced approach for measuring the Young’s moduli of thrombus-mimicking phantoms. Approach. Magnetomotive ultrasound (MMUS) has shown promise for lending specific contrast to thrombi by applying a temporally modulated force to magnetic nanoparticle (MNP) contrast agents and measuring resulting tissue displacements. However, quantitative elastometry has not yet been demonstrated in MMUS, largely due to difficulties inherent in measuring applied magnetic forces and MNP densities. To avoid these issues, in this work magnetomotive resonant acoustic spectroscopy (MRAS) is demonstrated for the first time in ultrasound. Main results. The resonance frequencies of gelatin thrombus-mimicking phantoms are shown to agree within one standard deviation with finite element simulations over a range of phantom sizes and Young’s moduli with less than 16% error. Then, in a proof-of-concept study, the Young’s moduli of three phantoms are measured using MRAS and are shown to agree with independent compression testing results. Significance. The MRAS results were sufficiently precise to differentiate between thrombus phantoms with clinically relevant Young’s moduli. These findings demonstrate that MRAS has potential for thrombus staging.
A study on MOCVD growth window for high quality N-polar GaN for vertical device applications
Authors: Soman Rohith , Noshin Maliha , Chowdhury Srabanti 
Published: July 2022

Abstract
Lateral N-polar GaN devices have outperformed Ga-polar GaN counterparts in mm-wave applications. A vertical N-polar GaN device structure with higher breakdown voltage is expected to further improve the output power density. This paper is aimed at understanding the growth conditions for such a vertical N-polar GaN device stack. A vertical device stack requires high-quality n-GaN layer with low unintentional dopant concentration and high electron mobility for better ON resistance–breakdown voltage performance. A systematic study by varying reactor temperature, pressure and NH3 flow rate is performed in the metal organic chemical vapor deposition growth of N-polar GaN for vertical device structure. Structural quality of the sample is increased with increase growth temperature and higher NH3 flow rate, yet an increase in surface roughness is observed for highest temperature used. The N-polar GaN grown at the optimized conditions exhibited a x-ray diffraction rocking curve full width half maximum of symmetric (0002) and skew-symmetric (20

The optimized sample exhibited a low screw dislocation density of 2.5 × 108 cm−2 on sapphire substrate. A gradual increase in the bulk mobility of electrons with decrease in screw dislocation density in N-polar GaN is also reported.
Evolutionary algorithm to design high-cooperativity optical cavities
Authors: Karpov Denis , Horak Peter 
Published: July 2022

Abstract
Using an evolutionary algorithm combined with a gradient descent (GD) method we design optical cavities with significantly enhanced strong coupling rates between cavity photons and a single quantum emitter. Our approach allows us to find specially designed non-spherical mirrors which lead to high-finesse cavity eigenmodes with large field enhancement at the center of the cavity. The method is based on adding consecutive perturbations to an initial spherical mirror shape using the GD method for optimization. We present mirror profiles which demonstrate higher cavity cooperativity than any spherical cavity of the same size. Finally, we demonstrate numerically how such a cavity enhances the operation frequency and purity of coupling a Ca+ ion to an optical fiber photon.

Abstract
The initial operation of neutral beams in Wendelstein 7-X enabled the first measurements of carbon (C6+) temperature and rotation with a multi-chord charge exchange recombination spectroscopy system. In this article we analyse the velocity measurements obtained with this system to infer the profiles of radial electric field, E
r, and net parallel velocity of fully stripped carbon ions, V
‖. We include a general treatment of the flow geometry and the velocity corrections due to the energy dependence of the charge exchange cross section. The inverted profiles are compared with neoclassical calculations for various plasma conditions and two magnetic configurations. It is found that both the E
r and V
‖ experimental profiles agree in sign and order of magnitude with the neoclassical expectations and reproduce the expected dependencies on plasma parameters and magnetic configuration, within the reduced dataset presented. However, quantitative differences with respect to the neoclassical profiles are observed above the estimated errors in various conditions.
Implementation of microseismic monitoring for iron ore mines
Authors: Bakai A V 
Published: July 2022

Abstract
The seismic station of the Subbot Institute of Geophysics of the NAS of Ukraine (IGP), in Kriviy Rih (Ukraine) ten earthquakes were registered from 2007 to 2013. Such activity is not typical for this region. One of the reasons is mining of mineral resources in this area, leading to irreversible changes in the stress-strain state of the massif, which activate dangerous natural and man-made processes (landslides, flooding, earthquakes, mountain strikes, etc.) The collapse of the mountain massif and the exit of the funnels occurs when the limit value of the loading in the massif is reached. Limit value warning of the stress-strain state of the massif is a condition for the danger of the zone. The task of control is to prevent the stress-strain state of the massif. Any unloading of the massif is accompanied by the formation of a crack, which is characterized by a burst of amplitude and a certain frequency of oscillations. For the geographic information system of mines, it is important to highlight significant phenomena by types of energy, affiliation to the mining allotment of the mine (distance to the hypocenter) and the nature of the primary source - technical or natural. The goal of research is to define a significant phenomena for identifying the stress-strain state of the massif using the microseismic monitoring. To increase noise immunity, it is advisable to use both physical filtration methods and software selection of significant phenomena against the background of man-made noise. To form conclusions, it is necessary to form a sample, so for reliable identification of the stress - strain state of the massif it is necessary to perform statistical processing of the measurement results. The usage of microseismic control at mining enterprises will reduce the possibility of mining shocks, landslides, which will reduce material damage. This will increase the safety of mining operations and ability to prevent man-made earthquakes of magnitude more than five.
Stress environment around head entries with pillarless gobside entry retaining through numerical simulation incorporating the two type of filling wall
Authors: Sakhno I G , Sakhno S V , Kamenets V I 
Published: July 2022

Abstract
Longwall mining is the most productive system for underground extraction of coal. Many coal mines use a pillarless mining. Reserving a gateroad for the usage of next panel mining is a popular gob-side entry retaining. Thus, the conventional entry retaining method requires an installation of filling walls. The mechanical properties of filling materials largely determine the quality of job-side entry retaining. Stress field evolution study around head entries when main roof console length increase with two variants of filling wall. Ansys code was used to analyze the stress evolution law under different mining conditions. As a result of numerical simulation, it was found that in the case of gob-side entry retaining, the localization of maximum stresses in surrounding rock is determined by the length console of the main roof, which hanging on the border with the gob, and the filling walls deformation module. Potential location of roof cutting, stress gradient and extremum stress in the main roof define the stability of entries. Main roof console length and filling material parameters control can help to the formation of a stable structure around the entry to meet the requirements of the next working face.

3 nanocomposite particles were synthesized at the first stage. In the next stage, magnetic core-shell particles were modified with amino groups followed by grafting onto their surface of the boronic acid derivative. Such a multifunctional material, containing both boron (B) and gadolinium (Gd) atoms is a promising candidate for developing films and membranes, strongly interacting with neutrons. Due to the presence of boronic acids and bound to the indicator (Alizarin Red S), the material can induce color changes while immersed in sugar-containing solutions. Such a feature enables a possibility to estimate the number of boron atoms left after interaction with neutrons, thus allowing to check composite neutron-capture recourse.

Published: July 2022

Abstract
The article considers the problem of human factor in complex polyergatic systems with a flow of applications for functions (problem solving) arising at random moments of time. The structure of a decision support system for the operator-manager, including subsystems of monitoring, forecasting and decision-making, is justified. The system of criteria relevant to solving the tasks of functions distribution was substantiated and its multi-criteria nature was shown. The technology of multi-criteria evaluation and choice of alternatives based on the methodology of hierarchical system analysis of problems and the method of analysis of hierarchies Thomas Saaty has been proposed. The decision-making system, which has been tested in the operation of control systems of various complex technical and production objects, has been implemented. The proposed method differs from the known approaches in that this method is aimed at prompt decision-making, as well as in that it uses a multi-criteria approach and both pragmatic and ergonomic criteria are used as criteria.
Adapting engineering education to challenges of sustainable development

Published: July 2022

Abstract
Textile and clothing industries generate a lot of waste at both production stages and in the process of wearing garments. Every inhabitant of developed countries annually wastes up to 30 kg of used but still suitable clothes, which decompose very slowly in natural conditions. The broadest possible implementation of textile waste processing technologies, such as downcycling and upcycling, is the key to ensuring the successful operation of the textile and clothing industries under conditions of sustainable development. The paper goal is to determine factors controlling students’ upcycling behaviour to strengthen the educational components and meet sustainable development challenges for the garment industry. Based on interpersonal and planned behaviour models, 93 students of 1-6 years majoring in clothing technology, design and sectoral professional education were surveyed to understand their upcycling behaviour. The surveyed students are divided into similar-sized groups of optimists (practice upcycling more than once every three months) and pessimists (less than once a year). Upcycling behaviour was shown to correlate with intentions, which are, in turn, affected by social factors, attitude, and perceived behaviour control. Perceived habits and facilitating conditions have a relatively small impact. There is almost no difference between students of different years of study and specialities. Students’ understanding of the benefits of upcycling is shallow and does not change with training years. Amid a highly-positive attitude towards upcycling, a low level of knowledge of the benefits and lack of progress with years indicate existing problems in developing upcycling behaviour in the learning process.

Published: July 2022

Abstract
To strengthen the sides of tailing dams and stockpiles, it growing forests from trees, shrubs and plant grass. Due to the difficult topography of the terrain, greening technologies require new ideas and material support. The objective of the research is to develop a technology for sowing large areas of plants with seeds from the air. In order to sow large areas with plants, it proposed to scatter seeds (grains) from a height onto hard-to-reach slopes, attached to a parachute system of a special design. Thousands of swarms of miniature capsules with seeds lifted by the drone and released by it at a given height will be scattered by the wind over large cultivated areas. The capsule filled with grain, fertilizer, humus and a compartment with water (gel). The parachute system is a three-dimensional paper platform that allows the capsule attached to it to fall smoothly and slowly. The hooked plumage of the platform provides its reliable grip on the ground. The platform is also soaked with seed nutrients before launch. Analytical, computational and experimental studies have confirmed the highly efficient aerodynamic properties of the developed parachute systems. 3D flying platforms demonstrated controlled rotation kinematics (18 rad/s) and low final speeds of 1.6-1.9 m/s.
