Environmental context Pesticides and other contaminants released by agricultural activities negatively impact aquatic biota and water quality, but are not always measured. The Polar Organic Chemical Integrative Sampler (POCIS) is among the most suitable tools for identifying pesticides and other organic compounds in water bodies. However, determination of a mean concentration (over the duration of the deployment) is still a significant challenge, which is addressed in the present work using field observations and a computational model. Rationale The Polar Organic Chemical Integrative Sampler (POCIS) is a passive sampler composed of a receiving phase, Oasis HLB, enclosed between two polyethersulfone (PES) membranes. It is used for monitoring organic compounds in surface water and in groundwater. The measurement of pesticide concentrations by passive samplers in streams still represents an open challenge, which limits the samplers’ use in environmental monitoring of the quality status of water bodies in accordance with the EU Water Framework Directive. Methodology We addressed these limitations by calibrating a POCIS with concentration measurements performed on samples collected by means of an automatic sampler from the same section of a small alpine river where a passive sampler was deployed. In the majority of published studies, the analytes were extracted only from the receiving phase, but recent works show that some compounds were also adsorbed by the PES membrane, suggesting the importance of extracting the analytes from both the phase and the membrane. Results The POCIS was calibrated for 31 compounds, by a comparison between the total amount of pesticides adsorbed by POCIS (Ms) and the time-weighted average concentration (TWAc) obtained from several grab samples, and by estimation of the sampling rate (Rs), which allows linking the Ms with the TWAc over time. The data showed an increasing Rs trend with hydrophobicity for the most hydrophobic and hydrophilic compounds, while compounds with 1.5 ≤ log Kow ≤ 3.5 assumed a value of Rs independent of log Kow. The contribution of PES membranes allows expansion of the calibration of Rs to the most hydrophobic compounds and allows monitoring of pesticides that would hardly have been detected if they were extracted only from the Oasis HLB phase, such as fluazinam. Discussion The calibration was then verified on the same stream and the model extended to a different sampling site; in both cases, the calibration allowed estimation of a value of TWAc that fits with the reality within a factor of 5, and in the majority of cases within a factor of 2. If this level of accuracy is accepted, the Rs reported here can be used to estimate TWAc from sampling with POCIS.
The {bei+verb+jiangqu} construction in pre-twelfth century Chinese
Authors: Sun Jianqiang 
Published: September 2023

Abstract
The Chinese string composed of {bei 被 + verb + jiang 將 + qu 去} is a rare, unique, unproductive, informal usage which, to date, has remained virtually unexplored. The present paper attempts to sketch its pre-twelfth century evolution by analyzing examples collected from various sources, but now from sources digitalized by CBETA (
Chinese Buddhist Electronic Text Association
). This paper begins by investigating the constituents in order to determine a core structure. It argues that jiang and qu are not two discrete elements but one single unit, reanalyzed in a new formula, {bei + verb + jiangqu} to replace the traditional notation {bei + verb + jiang + qu}.
Regarding the evolution of this collocation, the paper periodizes four stages of development. (1) The earliest examples appear in the fifth century, and they are of the {bei + verb₁ + verb₂ (+ verb₃)} order, in which jiangqu occupies either the second or third verbal slot. (2) Seventh century examples are showing signs of change, allowing, for the first time, an agent to be inserted between bei and the verb. (3) The eighth century witnesses a radical usage shift in which jiangqu has been demoted to a SIFE (“Semantically Impoverished Functional Element”), resulting in a new passive order {bei + verb + SIFE}. (4) The evolution continues in the ninth through eleventh centuries, becoming more complex, though somewhat dormant. This paper thus contributes to discussion of an understudied and thorny topic: How to segment short strings of Chinese characters. A few guidelines are suggested, and it is noted that some strings consisting of “verb, jiang, and qu” have been wrongly dissected: {verb + jiang + qu} must be rendered {verb + jiangqu}.
The drama of dialogue action in distinct discourse spaces
Authors: Chłopicki Władysław 
Published: September 2023

Abstract
The article addresses the issue of intracultural dialogue between two strong political mindsets, liberal and
conservative. This polarization is typical of contemporary cultural divides and emerges in the public sphere through mass media,
often finding its outlet through humour, which may be treated as a mediating factor. It will be discussed on the example of a
popular Polish humorous talk show broadcast on the public TV channel as compared to one broadcast on commercial television. The
central finding of the study, seemingly replicable for other languages and television cultures, is the discovery of the central
item on the discursive agenda, i.e., a worldview hiding in the conservative epistemic stance that assumes the authority of the
journalists running the show.
How to break a norm and get away with it
Authors: Yu Jing 
Published: September 2023

Abstract
Norm conformity and violation constitute two sides of norm operation: the former maintains the stability of the
system while the latter motivates its modification, evolution, and change. While previous studies have concentrated on the
constraints of norms in translators’ behaviour and their conformity to them, few have examined norm violation, especially why
translators choose violation over conformity and how they get away with the violation. This study explores motivation and risk
management concerning norm violation based on a case study of two Chinese translators who violated the norm of standard Chinese
and got away with it when translating a dialect in the source text. The case study shows norm violation is the result of an
optimal trade-off between translators’ reward-seeking behaviour and risk management in their negotiation with multiple conflicting
norms, rather than an abnormal behaviour involving negative consequences, as suggested in previous studies. Whether one can get
away with the violation is often related to its impact on the system. The study contributes to norm studies by illuminating the
complexity of norm-governed behaviours and norm violation, offering new insights on norm dynamics and risk management in
translation.

Abstract
Aiming at the problems of misdetection, omission and low recognition accuracy of coal gangue recognition due to the harsh environmental factors such as low illumination, motion blur and large quantities of coal gangue mixing in coal mines, a coal gangue recognition method based on XBS-YOLOv5s is proposed. Simulate the actual underground production environment to build a machine vision platform, construct a coal gangue image data set, and provide a test environment for various target detection algorithms. In this paper, we construct a real-time detection model of coal gangue in the complex environment of coal mine by fusing SimAM parameter-free attention mechanism, BiFPN feature fusion network and XIoU loss function in YOLOv5s, so as to improve the model’s ability of extracting, fusing and localizing key features of the target. The experimental results show that the recognition accuracy of XBS-YOLOv5s algorithm for coal gangue in the complex environment of low illumination, motion blur and large quantities of coal gangue mixed are effectively improved. Its mean average precision reaches 96%, which is 4.3% higher than the original YOLOv5s algorithm, meanwhile, compared with other YOLO series algorithms, it has the best comprehensive detection performance, which can provide technical support for intelligent and efficient sorting of coal gangue.
Solving the issue of increasing forming voltage during device miniaturization in hafnium oxide-based resistive access memory using high-k sidewall material
Authors: Yang Fei , He Zijian , Liu Bingkun , Hu Bo , Lou Shilong , Li Duogui , Wang Wentao 
Published: September 2023

Abstract
An electrothermal coupling model of resistive random access memory (RRAM) was established based on the oxygen vacancy conduction mechanism. By resolving the partial differential equation for the coefficients, the variation process of the device resistance was simulated. In our studies, a device model was proposed which can accurately simulate the whole process of RRAM forming, reset, and set. Based on the established model, a new high dielectric constant (high-k) material (La2O3) is introduced as the sidewall material. The La2O3 sidewall material can concentrate the electric field and helps to speed up the formation of conductive filaments. The La2O3 sidewall can effectively reduce the forming voltage increase during the miniaturization process. Then, the influence of sidewall thermal conductivity on forming voltage is studied, and it is discovered that low thermal conductivity helps to reduce the model’s forming voltage and increase the temperature concentration. These findings serve as a foundation for more studies on the choice of sidewall materials.
Speed limits and locality in many-body quantum dynamics
Authors: (Anthony) Chen Chi-Fang , Lucas Andrew , Yin Chao 
Published: September 2023

AbstractWe review the mathematical speed limits on quantum information processing in many-body systems. After the proof of the Lieb–Robinson Theorem in 1972, the past two decades have seen substantial developments in its application to other questions, such as the simulatability of quantum systems on classical or quantum computers, the generation of entanglement, and even the properties of ground states of gapped systems. Moreover, Lieb–Robinson bounds have been extended in non-trivial ways, to demonstrate speed limits in systems with power-law interactions or interacting bosons, and even to prove notions of locality that arise in cartoon models for quantum gravity with all-to-all interactions. We overview the progress which has occurred, highlight the most promising results and techniques, and discuss some central outstanding questions which remain open. To help bring newcomers to the field up to speed, we provide self-contained proofs of the field’s most essential results.

Published: September 2023

Abstract
TWAS technology is established and widely used in practice for spraying metal alloy-based coatings, benefiting from the low cost of the device and the mobility, enabling the application of the coatings even on large structures without the need for disassembly. TWAS coatings properties and performance depends not only on the chosen type of the material but also on the deposition process parameters, which must be carefully chosen so that the properties of the resulting coating meet expectations. This paper presents the results of the spraying parameters optimization study, obtained using the multiparametric regression statistic model. 16 different composition of metal wires were included in the study. The results of the statistical analysis are supported by the microstructural analysis, carried out using optical microscopy. The compressed air pressure and the current were identified as significant variable, influencing the coating hardness and deposition rate.
Aluminium oxide grid blasting: grid size and blasting pressure influence on the substrate surface contamination, roughness and ceramic plasma spray coating adhesion strength
Authors: Antoš J , Duliškovič J , Bejblíková S 
Published: September 2023

Abstract
This paper concerns influence of grit blasting parameters (grid blast media size and blasting pressure) on blasted surface contamination by entrapped grid blast particles and roughness of a blasted mild steel surface and a subsequent influence of given surface specifications on a thermal spray coating adhesion strength. Main goal of an experiment presented in this paper is basic optimization of grid size of alumina oxide blasting medium and blasting pressure in order to reduce surface contamination by grid residues trapped on the surface. Those residues are known to cause reduction in adherent forces between coating and blasted substrate, functioning as major stress concentrators especially under high mechanical and/or temperature loads. Mutual relations between grid size and blasting pressure as input parameters, and surface contamination, surface roughness and adhesion of an atmospheric plasma sprayed ceramic coating is evaluated. It was found that higher surface roughness does not necessarily lead to higher adhesion of thermally sprayed coating. The resulting adhesion strength seems to be determined by the synergistic effect of the suitable roughness profile, residual blasting particles and feedstock particle size of the deposited coating. This is supported by the observed highest adhesions (around 22 MPa) of ceramic alumina-titania APS coating to the surface with lowest measured roughness (as low as Ra 2.7) but also the lowest contamination level by blasting residues (4.6 to 6.7 %).

Published: September 2023

Abstract
Cold spray technology (CS) as an advanced surface treatment can also be applied in the field of energy. Depending on the type of spraying, the coating itself plays the role of protecting the surface from corrosion, abrasion and other operational influences. In the case of dissimilar metal welds (DMW), it can play the role of protection against stress corrosion cracking (SCC). The thickness of the applied spray can range from tens of microns to units of mm. The quality of NiCr and Ni protective coatings made by CS technology was tested by means of non-destructive (NDT) and destructive (DT) testing. NDT focused on measuring the attenuation of the ultrasonic signal, measuring the thickness of the applied coatings and the adhesion to the base material using pulsed echo (PEUT) and phased array (PAUT) ultrasonic testing techniques. Evaluation of the microstructure, porosity and corrosion stability of CS coatings before and after the salt spray test was performed metallographically.

Abstract
When crushing various raw materials of mineral, vegetable and animal origin hammer crushers of various designs are widely used, in which the rotor with hammers attached to it can be located both horizontally and vertically. During the operation of a hammer crusher with a vertical axis, a stable air-grain layer is formed near its deck, upon contact with which the crusher hammers wear out, and the wear itself depends on the contact stresses acting in the layer and the path (stay time) of the hammers in it. The problem posed is similar to the well-known problem of applied physics about a rotating disk, with the difference that tensile stresses act on the disk, and compressive stresses act on the air-grain one. The article obtained a theoretical expression for the linear wear of the crusher hammer, which depends on the characteristics of the layer, the properties of the crushed material and the grinding time, and in a complex way - from the distance from the edge of the hammer to the axis of its suspension. A comparison of the theoretical wear curves with the real outlines of worn hammers shows their identity.

Abstract
It has been experimentally established that spectroscopic methods can be used to create a technological process condition for the development of methods for obtaining natural dyes used in the food and pharmaceutical industries. It is shown that the use of spectroscopy makes it possible to obtain coloring pigments rich in biologically active molecules, vitamin preparations and vital elements potassium, Ca, Fe, carotenoids, anthocyanins and flavones. The developed method can also improve the technology of obtaining products with high qualities with increased shelf life. The composition of the final product does not allow starch, herbicides, inorganic compounds that lead to obesity of the body.
Investigations of the formation of nanosized objects in manganese implanted silicon single crystals by the methods of Raman scattering of light and atomic force microscopy
Authors: Arzikulov E U , Salakhitdinov F A , Kholmurodov F , Tashboev M D 
Published: September 2023

Abstract
This article presents the results of experimental studies on the formation of nanosized objects in single crystals of silicon ion-implanted with manganese ions with an energy of 40 keV at various doses. The formation of nanosized objects was determined by atomic force microscopy (AFM) and Raman spectroscopy (RS). It was found that in the Raman spectrum of non-implanted samples there are peaks with a wave number of 520 cm-1 characteristic of pure silicon associated with the crystalline phase and satellites with frequencies 301 cm-1, and 971 cm-1. The band with a wave number of 971 cm-1 corresponds to the main band of the tetrahedral bond in silicon. The intensity of this peak depends on the sample thickness. When the sample thickness changes from 200 μm to 3 mm, the intensity of this peak decreases by almost two times. And in the Raman spectra of ion-implanted samples, several bands with different intensities are observed, and their number and intensity strongly depend on the implantation dose. It has been suggested that the observed peaks are possibly associated with radiation defects and nanosized formations. This assumption was verified using AFM investigation. The AFM images show various nanosized objects, apparently associated with manganese ions.

Fabrication of multi-compartmental vesicles via RAFT method in polymerization-induced self-assembly
Authors: Kadirkhanov Jamshid , Yusupov Muzafar 
Published: September 2023

Abstract
Synthetic polymer nanomaterials have sparked considerable attention because to their use in a wide range of fields, including medication delivery, sensors, nano reactors, and catalytic supports. A popular approach for creating polymer nanoparticles is self-assembly of block copolymers in a diluted solution. Generally, the preparation of fine structural nanoparticles involves several steps, including the synthesis of block copolymers, exhausting purification to obtain perfect block copolymers, diluting the obtained block copolymers in a suitable solvent, and then cautiously replacing the decent solutes with a selective solvent. Furthermore, typical polymer nano-object manufacturing is frequently done in high dilution (concentration is usually below 1%). The procedure for producing block copolymers and allowing them to self-assemble is combined into one stage by polymerization-induced self-assembly, which significantly streamlines the creation of polymeric nanostructures and enables the fabrication of such materials at high concentrations (solid concentrations of 10–50%). This work used styrene as the monomer, E/W at a weight ratio of 7:3 as the solvent, and polyethylene glycol (PEG45-PETTC) as the macro-RAFT reagent to successfully create multi-chambered vesicles.

Published: September 2023

Abstract
IR spectra and electrical resistance of defective manganese sulfide with the substitution of manganese ions with samarium ions in the of 80-500 K are investigated. The maxima of the temperature coefficient of electrical resistance and anomalies of conductivity are attributed to spin and lattice polarons. Absorption bands have been found in the IR spectra, that due to oscillations of octahedra and lattice polarons. From the Hall measurements, the type of current carriers, concentration and mobility of hole and electrons are estimated.
Precession of magnetic moments with change of their orientations
Authors: Zhumaev M R , Sharipov M Z , Rizokulov M N 
Published: September 2023

Abstract
In the work the precession of the magnetization vector in nano-sized magnets is induced by a femtosecond laser pulse, the frequency of which lies in the transparency region of the magnet material. It is shown that an alternating magnetic field applied to the XOY plane generates the magnetic equilibrium position vectors and elliptical precession occurs if a constant magnetic field acts along the Z axis. In this case the precession angle changes periodically in time and the precession frequency is determined by the amplitude of the total magnetic field.

Published: September 2023

Abstract
The main task of the technological process in existing spinning systems in the processing of natural, artificial and synthetic fibers into yarn is to obtain a ribbon, rovings and yarn uniform in structure and properties by folding and drawing. The article studies analytical dependences for calculating the angle of flow around the exhaust cylinder by the lobe on the spinning line of ring spinning machines. Analysis of the results of the experiment allows us to conclude that ensuring a constant clamping of the straps in the exhaust zone reduces the unevenness of the product during stretching.
