Repetitive constructions and stance-marking
Authors: Koo Hyun Jung , Rhee Seongha 
Published: February 2023

Abstract
Korean has highly formulaic patterns of repeating a sentence two or more times with a variation of speech level indicated by the sentence-final particles. The repetition usually involves progressive downward modulation of the speech level from more formal to less formal. The repeated sentences occur within a single intonation contour, thus forming an utterance unit, and carry diverse intersubjective and interpersonal functions that are not available in the mere repetition of an identical sentence. By virtue of having the pairing of a syntactic pattern and a non-compositional meaning, these patterns are best considered a construction, named here as Multiply Juxtaposed Sentences (MJSs). MJSs encode the speaker’s subtle negative attitude toward the addressee.
Are referent introductions sensitive to forward planning in discourse?
Authors: Schnell Stefan , Haig Geoffrey L.J. , Schiborr Nils Norman , Vollmer Maria 
Published: February 2023

Abstract
It has been argued that speakers employ morphosyntactic structures such as presentationals and left-dislocations (Lambrecht 1994) to establish new entities in discourse due to considerations of referent accessibility vis-à-vis event processing (Du Bois 1987; Chafe 1987). We here investigate whether introductions are sensitive to the salience of the discourse referent in subsequent discourse (Himmelmann 1996; Lichtenberk 1996). This hypothesis is tested against spoken corpus data from twelve diverse languages. While the use of specific morphosyntactic structures does correlate with discourse prominence, humanness has a much stronger effect. Subsequent discourse salience is hence not the chief determinant of the syntactic positions of new mentions; the convergence of humanness and semantic role associations in specific syntactic positions better explains the attested patterns.
Differential indexing and information structure management
Authors: Just Erika 
Published: February 2023

Abstract
Differential indexing has often been associated with features such as animacy and identifiability, but also with the discourse categories topic and focus. This study presents a cross-linguistic survey of differential indexing phenomena which have been ascribed to topicality or focus, showing that although there are similarities with regard to the discourse-structural effects that the addition or omission of indexes might have in different languages, differential indexing has language-specific, often compositional causes and effects. These are demonstrated by two case studies, on Ruuli (Bantu) and Maltese (Semitic). In both languages, differential indexing of the P argument could be ascribed to the topicality of the referent, but it will be shown that this would not do justice to the multifactorial reality of the phenomenon, as in both languages, differential indexing is triggered by a complex interplay of different factors.

Published: February 2023

Abstract
This study proposes an online practicum model supported by Wireless Sensor Network (WSN) to implement a physics practicum after the Covid 19 Pandemic. This system is guided by exploratory inquiry questions to help structure students’ mindsets in answering investigative questions. Online practicum is also integrated with video conferencing, chat, evaluation system, and lab inquiry stages. The sensor measurement process is carried out directly via live streaming video, where the sensor measurement results are sent in real-time to the website via an internet connection. This study was conducted on 25 students (10 male and 15 female) who were prospective physics teachers. This study used a pre-experimental method with a one-group pretest and post-test design. The study results show that the online practicum model supported by WSN can effectively increase the inquiry skill of prospective physics teacher students. Usability test results obtained an average score of SUS 91.63, which means the practicum system can be categorized as having a user acceptance level of Excellent.
A new global model with two electron groups for weakly ionized argon discharges at low pressure
Authors: Lei Zhi-Cheng , Pu Yi-Kang 
Published: February 2023

Abstract
A new global model is developed for weakly ionized argon discharges at low pressure with a non-Maxwellian electron energy distribution. This model adopts the ‘two-electron group approximation’, as done in reference (Vriens L 1973 J. Appl. Phys.
44 3980; Ligthart F A S and Keijser R A J 1980 J. Appl. Phys.

28 841), but the effective temperatures for both groups of electrons, the energy boundary between them in energy space and the total volume-averaged electron density are all obtained in a self-consistent manner. By treating low- and high-energy electrons as two different species and involving particle and energy balance equations for both of them, the model-predicted electron distributions agree well with the measured ones under a wide range of discharge conditions. A detailed comparison between the results from the model presented in this work and those from the previous models is also made, along with the discussion of the reasons that cause the differences.

Abstract
The CMS collaboration has made some of their data public, making it possible for external users to perform physics analysis using real data. In this work, we report the measurement of jet properties such as fragmentation function, and the average multiplicity distribution of leptons and charged hadrons within the jets, all of them produced in pp collisions at

s

Jet∣ < 2.1 and E
Jet > 120 GeV respectively. For the study we used the anti − K

algorithm applied to four samples of 2011 CMS open-data, to explore the possible differences obtained by using different trigger conditions, and the results are compared with predictions from the Pythia 8 event generator.
Characterization of the hydrogen plasma in the RF negative ion source by optical emission spectroscopy
Authors: Li Zengshan , Yang Jinghan , Li Dong , Chen Peng , Zuo Chen , Chen Dezhi 
Published: February 2023

Abstract
Optical emission spectroscopy (OES) is an important noninvasive diagnostic tool for providing insight into the plasmas of the negative ion sources. The plasma spectroscopic characterization of the RF driven negative ion source at Huazhong University of Science and Technology (HUST) is studied with the delivered power from 6 kW to 16 kW. The gas temperature, electron temperature, electron density and the density ratio of atomic hydrogen to molecular hydrogen are extracted from OES. The gas temperature is estimated from the Fulcher band of H2. A global thermal model is developed to investigate the gas heating mechanisms in hydrogen plasmas. The gas temperature calculated by the model using the electron density and electron temperature from OES as input parameters is in good agreement with that from the experiment. The thermal model shows that the dissociation of molecular hydrogen by electron impact is the dominant source of gas heating and that approximately 11% ∼12% of the delivered power is dissipated in gas heating at 0.3 Pa filling pressure. Moreover, the electron temperature, electron density and the ratio of atomic to molecular density are obtained from the absolute intensity of Balmer lines and Fulcher band by using collisional radiative (CR) models of H and H2. The kinetics of the excited states of H are also discussed.

Authors: Ghosh Arindam , Maitra Sarit 
Published: February 2023

Abstract
In this work the (2+1) dimensional integrable Maccari system is studied. An effective algorithmic method—the multiplier approach for finding the conservation laws of system of partial differential equations is discussed and used to find the conservation laws for this system. Infinite number of conserved vectors are found which strongly support the integrability aspects of the Maccari system. Also new exact solution for this system is derived by using the extended homogeneous balance method. The obtained solutions are plotted and they show bright and dark soliton nature.
Quantum counterfactuality with identical particles
Authors: Rao Vinod N , Banerjee Anindita , Srikanth R 
Published: February 2023

Abstract
Quantum self-interference enables the counterfactual transmission of information, whereby the transmitted bits involve no particles traveling through the channel. In this work, we show how counterfactuality can be realized even when the self-interference is replaced by interference between identical particles. Interestingly, the facet of indistinguishability called forth here is associated with first-order coherence, and is different from the usual notion of indistinguishability associated with the (anti-)commutation relations of mode operators. From an experimental perspective, the simplest implementation of the proposed idea can be realized by slight modifications to existing protocols for differential-phase-shift quantum key distribution or interaction-free measurement.

Authors: Xu Li-Yang , Yin Xiao-Jun , Cao Na , Bai Shu-Ting 
Published: February 2023

Abstract
We study a coupled Schrödinger equation which is started from the Boussinesq equation of atmospheric gravity waves by using multiscale analysis and reduced perturbation method in this paper. For the coupled Schrödinger equation, we obtain the Manakov model of all-focusing, all-defocusing and mixed types by setting parameters value and apply the Hirota bilinear approach to provide the two-soliton and three-soliton solutions. Especially, we find the all-defocusing type Manakov model admits bright-bright soliton solutions, what’s more, we find the all-defocusing type Manakov model admits bright-bright-bright soliton solutions. Following that, we go over how the free parameters affect the Manakov model’s all-focusing type’s two-soliton and three-soliton solutions’ collision locations, propagation directions, and wave amplitudes. These findings are useful for setting a simulation scene in Rossby waves research. The answers we have found are helpful to study the equation’s physical properties in Rossby waves.
Zinc ash deposition pattern and structural optimization in the continuous hot-dip galvanizing vertical furnace

Published: February 2023

Abstract
In a continuous hot-dip galvanizing vertical furnace for strip steel, zinc vapor oxidizes in the snout of the furnace to form zinc ash. The zinc ash adheres and agglomerates on the inner walls of the snout. If the zinc ash falls off and adheres to the surface of the strip, zinc ash defects will be formed, thereby affecting the surface quality of the galvanized layer. Given that the snout connects the annealing furnace and the zinc pot, the zinc ash will be transported into the annealing furnace and form nodulation on the roller, affecting the normal operation of the equipment. To study the deposition pattern of zinc ash inside the snout, a model of particle movement and deposition is established in this work to predict the movement and deposition characteristics of zinc ash particles, and it is verified by literature. On this basis, the zinc ash deposition patterns of three improvement cases of snout structure are compared. Results show that all three improvement schemes can effectively reduce the deposition rate of the zinc ash particles in the annealing furnace. In the case of slotted-baffle-added-only, although adding slotted baffles reduces the deposition of zinc ash in the furnace, it also increases the deposition rate in the snout and entry sections. In the case of exhaust-duct-added-only, the addition of the exhaust duct not only reduces the overall deposition rate in the furnace, but also effectively reduces the deposition rate in the snout and the entry section. By contrast, the scheme with slotted baffles and exhaust ducts is the most effective in inhibiting the diffusion of zinc ash.
Study on Coordinated Control of New Energy Over-Frequency Ride-Through and Over-Frequency Generator-Tripping Scheme
Authors: Bing Zeng , Yanxia Qu , Chunyu Zhang 
Published: February 2023

Abstract
After the fault isolation of the outgoing power grid with a high proportion of new energy, the high-frequency shutdown of the third line of defense is an important control measure to restrain the rise of the frequency of the sending-end power grid. With the increase in the proportion of intermittent power sources such as wind power and photo-voltaic power, the frequency characteristics of the power grid have become more complex. Considering the response characteristics and emergency control capabilities of wind power and photo-voltaic power, this paper proposes a high-frequency ride-through control strategy based on new energy stations. Through coordinated control with high-frequency shutdown measures, the new energy stations can rapidly reduce their power to replace some costly conventional unit operations to achieve more economical frequency safety control, after the high-frequency machine switching round action is executed to avoid over-switching triggering low cycle load shedding when the frequency is reduced to the threshold value, it will trigger the rapid recovery of new energy power generation to meet the requirements of refined frequency stability control of modern power grids. Based on the actual planning of the high-voltage transmission end grid scale, a simulation system was built, and a new energy high-frequency ride-through model was built, which verified the feasibility of the proposed coordinated control scheme for high-frequency switching off with a high-frequency ride-through, and verified the adaptability of the proposed scheme under different operation modes.

Published: February 2023

Abstract
As an important technology to achieve energy restructuring, electricity storage plays an important role in the mission of carbon neutrality in today’s society. Compressed air energy storage is one of the most promising technologies for medium- and small-scale power storage. Single screw expander as an important energy conversion equipment in the compressed air energy storage, the stability of its performance is the key to ensure the normal operation of the energy storage system. In this study, based on the resonance problem of single screw expander in variable speed operation and the modal parameters of internal key components structure, the research is carried out. The results show that: The single screw expander can cause a large resonance damage when the rotational speed is working under 1950 – 2380 rpm. The natural modal frequencies of gate rotor, screw rotor and main shaft are not the cause of resonance. Through the work of this study, the influence of internal key components structure on resonance is eliminated, and the next research direction is defined.

Authors: Wang Yaohui 
Published: February 2023

Abstract
In this paper, an automatic liquid level monitoring device is designed, its working principle and technological process are described, and a workover dynamic liquid level testing scheme is established. In view of the factors affecting the sound velocity in the annular space of the oil jacket, the calculation formula and mathematical model of the sound velocity and the depth pressure temperature density are established. The sound velocity changes caused by the changes in temperature, pressure and the composition of the well gas are accurately corrected. It is confirmed that the modified model provides a method that can not only ensure accuracy but also greatly reduce the calculation amount, greatly simplifying the real-time calculation amount of the system. The obtained liquid level depth is approximate, but it is sufficiently accurate to meet the requirements of the technical indicators of the project.

The Zero Degree Calorimeters (ZDC) were designed to provide the measurement of the event geometry and luminosity in heavy-ion operation. The readout system was redesigned in order to operate in continuous mode without dead time at 2.5 MHz event rate. The new acquisition chain is based on a commercial 12 bit digitizer with a sampling rate of about 1 GSps, assembled on an FPGA Mezzanine Card. The signals produced by the 26 ZDC channels are digitized, and samples are processed through an FPGA to extract information such as timing, baseline average estimation and luminosity.

Published: February 2023

Abstract
Electrical impedance tomography (EIT) has been gradually used in lung health detection. When the lungs are measured using EIT, the image quality is compromised by contour changes outside the thorax. In this paper, the shape measurement belts made by bend and inertial sensors are used to determine the specific information of the chest boundary of subjects. Three measurement belts are used to measure the chest cavity model. The measured model data are used to perform the simulation experiment of pulmonary EIT. The results indicate that the model measurement accuracy and the image accuracy are higher by the multi-sensor measurement belt. The multi-sensor measurement belt provides conditions for the wearable of pulmonary EIT equipment.
Why was the heat wave in the Yangtze River valley abnormally intensified in late summer 2022?
Authors: Zhang Daquan , Chen Lijuan , Yuan Yuan , Zuo Jinqing , Ke Zongjian 
Published: February 2023

Abstract
A record-breaking heat wave hit the Yangtze River valley during the boreal summer of 2022, and caused severe social and economic losses. One prominent feature of this long-lived heat event was its persistence and abnormal intensification in August. This study investigated the physical mechanisms be responsible for the intensification of this heat event in late summer under the background of a La Niña event. The prolonged heat event was directly related to the intensification and westward extension of the western North Pacific subtropical high (WNPSH), which can be attributed to the synergistic effects of an anomalous western North Pacific (WNP) anticyclone and the eastward extension of the South Asian high (SAH) in the upper troposphere. The anomalous anticyclone in the WNP, which was induced by negative sea surface temperature anomalies in the central tropical Pacific, strengthened in August. The positive sea surface temperature anomaly in the western Pacific warm pool and enhanced in-situ convection led to anomalous high pressure over the Yangtze River valley via the local meridional circulation. Atmospheric convergence and descending motion over the Yangtze River valley was amplified in August as a result of the zonal shift in the SAH from the Iranian Plateau to the Tibetan Plateau. The Silk Road pattern (SRP) index of August 2022 was the lowest since the 1990s. The abnormal negative phase of the SRP contributed to both the zonal shift in the SAH and the westward extension of the WNPSH, which led to the abnormal intensification of the heat event over the Yangtze River valley in August 2022.
The thermal response of permafrost to coastal floodplain flooding

Published: February 2023

Abstract
Flooding of low-lying Arctic regions has the potential to warm and thaw permafrost by changing the surface reflectance of solar insolation, increasing subsurface soil moisture, and increasing soil thermal conductivity. However, the impact of flooding on permafrost in the continuous permafrost environment remains poorly understood. To address this knowledge gap, we used a combination of available flooding data on the Ikpikpuk delta and a numerical model to simulate the hydro-thermal processes under coastal floodplain flooding. We first constructed the three most common flood events based on water level data on the Ikpikpuk: snowmelt floods in the late spring and early summer, middle and late summer floods, and floods throughout the whole spring and summer. Then the impact of these flooding events on the permafrost was simulated for one-dimensional permafrost columns using the Advanced Terrestrial Simulator (ATSv1.0), a fully coupled permafrost-hydrology and thermal dynamic model. Our results show that coastal floods have an important impact on coastal permafrost dynamics with a cooling effect on the surficial soil and a warming effect on the deeper soil. Cumulative flooding events over several years can cause continuous warming of the deep subsurface but cool down the surficial layer. Flood timing is a primary control of the vertical extent of the permafrost thaw and the active layer deepening.
