Linguistic purification of violence in the press: a comparative critical discourse analysis of execution news
Authors: Bunnag Orawee , Chaemsaithong Krisda 
Published: September 2023

AbstractThe aim of this study is to probe for the discursive construction of shared beliefs about capital punishment. Drawing upon a specialized corpus of execution news, the study explores representational practices, including social actor naming, action description, and incorporation of voices, and compares respective lexico-grammatical choices that are orchestrated to reconstruct the events of executions in Thailand from 1997 to 2017. The findings reveal that these discursive choices purify state killing and hide the violence of state killing. While representation choices become less overtly negative over time, the underlying ideological position of the press has not changed. Throughout these periods, executions are represented as a routine procedure by minimizing and/or concealing state agency and as a commensurate punishment for the executed individuals, while the law enforcement and justice systems in place are intertextually framed as unproblematic and effective in deterring crime, based on the perspectives of few elite sources. By way of demystifying subtle linguistic choices, this study makes transparent the way in which the press endorses, normalizes, and perpetuates favorable stances toward death penalty in a democratic society.

Published: September 2023

Abstract
As we encounter many disasters and crises worldwide, various forms of crisis intervention are utilized to assist those who are impacted. In the United States, animal-assisted crisis response (AACR), the use of highly trained and experienced therapy dogs to provide comfort and support to those in need, is becoming an essential post-crisis modality. However, maintaining qualified volunteers is challenging and research on the characteristics of AACR teams has been narrowly developed. Therefore, there is a growing need to better understand these specialized volunteer teams, both handlers and their canine partners.
This exploratory survey of 99 animal-assisted crisis responders investigated the qualities, backgrounds, perceptions, and experiences of these canine handlers and their dogs. Results from an online questionnaire showed that most handlers were women (88%), and the prevalent age range was 61–70 (45%). Most handlers were retired (46.46%) with an average volunteer experience in AACR of 5.7 years. The recognition of dominant organizations providing AACR was also studied in this research. Most volunteers were members of HOPE AACR (54.36%). Handlers shared their education, specific traits, and skills to provide effective AACR. The characteristics of the canine partners of AACR were also explored. The most common breeds for AACR teams were Golden retrievers (28.88%) and Labrador retrievers (18.88%). The authors additionally explored the handlers and the traits of their dogs, as well as their reason for volunteering in AACR. All participants viewed AACR as effective with most of the teams (80.68%) perceiving AACR as a highly effective intervention following crises and disasters. This research offers insights for AACR organizations on strategies to recruit and retain these specialized crisis providers.

Published: September 2023

Abstract
Passivation makes 2D hexagonal structure more stable than the planar variant. Surface fluorinated monolayer of GaN have been found to have ultra-wide band gap and have promising applications in optoelectronic conversion devices. In this work, using theoretical method, we have explored the thermal conductivity as well as the electronic structure of F–GaN. It has a low thermal conductivity of 7.67 W (mK)−1 due to the low group velocity and short phonon lifetime. The calculated direct band gap value is 4.63 eV, which could be modulated by strain and biaxial strain is found to more effective. Attractively, direct band gap can be maintained under tensile strain. Breakdown of symmetry by uniaxial strain lifts the band degeneracy of the VBM, which will lead to polarized light emission. The in-depth analysis shows that Ga–F as well as N–F bonds are strongly ionic, which is responsible for its low thermal conductivity and ultra-wide band gap.

Investigation of the equivalent circuit and performance of an ultrasonic transducer under a force load
Authors: Rao Zhongyu , Shi Dinghui , Ye Hongxian , Hu Xiaoping 
Published: September 2023

Abstract
In ultrasonic processing technology applications, the force load can cause a drift in the resonance frequency of the ultrasonic transducer and significantly reduce its mechanical quality factor. The traditional equivalent circuit of an ultrasonic transducer can only be used to calculate performance parameters without a force load but not with a force load. Based on Mason’s equivalent circuit, a new equivalent circuit for ultrasonic transducers under a force load is derived while considering the effects of the force load on the material parameters and various types of losses in piezoelectric ceramics. Furthermore, performance parameters are analyzed, such as the resonance frequency, effective electromechanical coupling coefficient, and mechanical quality factor. The ultrasonic transducer sample is produced and the experimental platform is constructed for applying force loads on the ultrasonic transducer. The theoretical model is verified by static loading on the ultrasonic transducer. The proposed equivalent circuit provides theoretical guidance for tracking the exact resonance frequency and performance parameters of force-loading ultrasonic transducers.

Published: September 2023

Abstract
In concealed underground projects, pile foundations may cause severe engineering accidents owing to factors such as construction technology, geological conditions, and material properties. Accordingly, the construction industry has invariably focused on developing high-precision, distributed, and low-cost monitoring and disaster warning methods. Therefore, a new sensing material, sensor-enabled piezoelectric geocable (SPGC), was developed to monitor the deformation and failure of a pile foundation. Three model piles were constructed, and packaging and layout processes for the SPGC sensing material were proposed. Moreover, a fiber Bragg grating (FBG) sensor and resistance strain gauge were installed for comparison. Pile foundation failure and static load tests were performed using a large servo hydraulic press. The monitored effect was evaluated by obtaining the impedance and voltage signals of the SPGC. Pile foundation failure test results show that the mutation of impedance and voltage signals can be used as combined monitoring data, and the electrical signal of the SPGC can be used in three stages of early warning response. These findings ensure that pile foundation damage can be located, damage precursors can be identified, and timely warning can be provided. The static load test results indicate that the SPGC data are in good agreement with the FBG sensor and strain gauge data. The impedance of the SPGC increases linearly with the load. Accordingly, a linear calculation formula relating impedance and strain is derived. The research results are expected to provide a new technical method for pile foundation construction and long-term operation and maintenance monitoring.
Convolutional modulation spectra of soliton molecular complexes in ultrafast laser
Authors: Zhao Qiuye , Zhang Yudong , Fang Zhen , Zhang Zuxing 
Published: September 2023

Abstract
Optical soliton molecules are common pulse states in dissipative system, and they can combine with each other to form soliton molecular complexes which exhibit cumbersome spectral characteristics. As there is an intrinsic connection between the spectra of the soliton molecules and soliton molecular complexes, we demonstrate that the spectra of soliton molecular complexes are the results of quadratic modulation between component solitons, through experimental verification and simulation analysis. Specifically, two strongly bound solitons modulate to form soliton molecules, and then the soliton molecules modulate with weakly bound soliton pairs to form soliton molecular complexes, which is called convolutional modulation. The results obtained have vital significance to better understanding of the intrinsic nature and interaction of the solitons. The formation of quadratic modulated spectra plays an inspiring role in the fields like modern fiber-optic communication systems, optical frequency combs and its related precision measurements and various practical applications.
Computer simulation of Fe epitaxial films on a Cu(100) substrate
Authors: Belim Sergey V , Tikhomirov Ilya V 
Published: September 2023

Abstract
The article addresses the problem of modeling thin epitaxial iron films on a Cu (100) substrate by calculating the surface potential. The purpose of the simulation is to determine the film structure. The model uses the paired Lennard-Jones potential to describe the interatomic interaction. We calculate the surface potential of the copper substrate using the first 10 surface atomic layers. The iron atoms in the first layer are placed in the minima of the surface potential. The surface potential of the monoatomic iron layer and the 9 copper layers underneath determine the position of the second iron layer. The position of atoms in the following layers is formed on the basis of similar calculations. Calculations show that the copper substrate stabilizes the fcc crystal lattice in the iron film at low temperatures. Bulk iron samples at low temperatures have a bcc crystal lattice. The period of the iron lattice along the substrate is equal to the period of the copper lattice. The crystal lattice period of iron perpendicular to the substrate has an intermediate value between the values for copper and for γ-ferrum. The interface effect causes additional vertical deformations in the first two layers of iron above the substrate.

Published: September 2023

Abstract
This paper questions the validity of t-NA/D-Nt technique for solar cell optimization and establishes the scientifically and experimentally-justified NA/D-Nt-t parameter optimization sequence for the same. Fundamental mathematical formulations considering numerous physical perspectives are presented for scientific justification of newly proposed optimization procedure. This is followed by an in-depth comprehensive analysis on sequence of parameter optimization applied in numerous widely-implemented solar cell fabrication techniques. It is found that, in each fabrication technique, the same optimization sequence of NA/D-Nt-t is implemented. Along with this, simulation study of sample solar cell is presented for further analysis of our conceptualization. It is identified that the time at which initial values of NA/D and Nt are replaced by the optimized ones to convert the initial solar cell to an optimized one, the value of absorber thickness at which solar cell produces maximum yield also changes. It was observed that NA/D-Nt-t optimization sequence increased device efficiency from 6.97% to 17.05% (144.6% increment) as compared to 55.8% increment from 6.97% to 10.86% in case of conventional t-NA/D-Nt optimization sequence. Moreover, only the NA/D-Nt-t approach produced EQE graph that matches with the experimentally-observed EQE curves of device. Hence, the newly proposed scientifically and experimentally-justified NA/D-Nt-t optimization sequence proposed for first time in this paper, truly optimizes solar cell device so that it offers maximum-possible efficiency reliably.
Probing massive neutrinos with the Minkowski functionals of the galaxy distribution
Authors: Liu Wei , Jiang Aoxiang , Fang Wenjuan 
Published: September 2023

Abstract
The characteristic signatures of massive neutrinos on large-scale structure (LSS), if
fully captured, can be used to put a stringent constraint on their mass sum, Mν
. Previous
work utilizing N-body simulations has shown the Minkowski functionals (MFs) of LSS can reveal the
imprints of massive neutrinos on LSS, provide important complementary information to two-point
statistics, and significantly improve constraints on Mν
. In this work, we take a step
forward and apply the statistics to the biased tracers of LSS, i.e. the galaxies, and in redshift
space. We perform a Fisher matrix analysis and quantify the constraining power of the MFs by using
the Molino mock galaxy catalogs, which are constructed based on the halo occupation distribution (HOD) framework with parameters for the SDSS Mr
< -21.5 and -22 galaxy samples. We find the MFs
give tighter constraints on all of the cosmological parameters that we consider than the power
spectrum. The constraints on Ωm, Ωb, h, ns
, σ
8, and
Mν
from the MFs are better by a factor of 1.9, 2.9, 3.7, 4.2, 2.5, and 5.7, respectively,
after marginalizing over the HOD parameters. Specifically, for Mν
, we obtain a 1σ

constraint of 0.059 eV with the MFs alone for a volume of only (1h

Optimizing solidification process in phase change energy storage units with sinusoidal wave-shaped fins
Authors: Kumar Aman , Maurya Ambrish 
Published: September 2023

Abstract
Phase change energy storage units have attracted considerable interest in the field of energy storage technology. To overcome the challenge of low thermal conductivity associated with phase change material (PCM) employed in these units, researchers have implemented fins with various shapes. In this study, a two-dimensional numerical model of a phase change energy storage unit with newly designed sinusoidal wave-shaped fins is developed. The analysis is done using commercial software ANSYS-Fluent in the transient state. The solidification process of the PCM is evaluated with enthalpy–porosity method. The validation of the model is done against an experimental result from a published article. The study focused on increasing the surface area of sinusoidal wave-shaped fins, achieved by increasing its crests and troughs counts, and to analyse its impact on the solidification process of the PCM. The thermal performances are evaluated quantitatively by analysing the solidified portion of PCM, temperature distribution, rate of heat release, and velocity variation. The result shows that the total solidification time predicted for straight fin is 115.34 min. This duration reduces for wave-shaped fins, and it reduces even further as the crests and troughs counts of wave-shaped fins increases. The maximum reduction in total solidification time is observed as 19.93% for wave-shaped fin with 10 crests and troughs counts. It is also observed that rate of reduction in total solidification time initially decreases then marginally increases with the increase in crests or troughs counts. The effect of buoyancy on the PCM flow velocity is analysed at different locations within the phase change energy storage unit. It is observed that with the increase in crests and troughs counts the movement of PCM near the crest or trough decreases.
Constructing Residential Histories in a General Population-Based Representative Sample
Authors: Xu Wei , Agnew Megan , Kamis Christina , Schultz Amy , Salas Sarah , Malecki Kristen , Engelman Michal 
Published: September 2023

Abstract
Research on neighborhoods and health typically measures neighborhood context at a single point in time. However, neighborhood exposures accumulate over the life course, influenced by both residential mobility and neighborhood change, with potential implications for estimating the impact of neighborhoods on health. Commercial databases offer fine-grained longitudinal residential address data that can enrich life-course spatial epidemiology research, and validated methods for reconstructing residential histories from these databases are needed. Our study draws on unique data from a geographically diverse, population-based representative sample of adult Wisconsin residents and the LexisNexis (New York, New York) Accurint, a commercial personal profile database, to develop a systematic and reliable methodology for constructing individual residential histories. Our analysis demonstrated that creating residential histories across diverse geographical contexts is feasible, and it highlights differences in the information obtained from available residential histories by age, education, race/ethnicity, and rural/urban/suburban residency. Researchers should consider potential address data availability and information biases favoring socioeconomically advantaged individuals and their implications for studying health inequalities. Despite these limitations, LexisNexis data can generate varied residential exposure metrics and be linked to contextual data to enrich research into the contextual determinants of health at varied geographic scales.
Modeling the structure of the transmembrane domain of T1R3, a subunit of the sweet taste receptor, with neohesperidin dihydrochalcone using molecular dynamics simulation
Authors: Nakagita Tomoya , Matsuya Takumi , Narukawa Masataka , Kobayashi Takuya , Hirokawa Takatsugu , Misaka Takumi 
Published: September 2023

ABSTRACT
Neohesperidin dihydrochalcone (NHDC) is a sweetener, which interacts with the transmembrane domain (TMD) of the T1R3 subunit of the human sweet taste receptor. Although NHDC and a sweet taste inhibitor lactisole share similar structural motifs, they have opposite effects on the receptor. This study involved the creation of an NHDC-docked model of T1R3 TMD through mutational analyses followed by in silico simulations. When certain NHDC derivatives were docked to the model, His7345.44 was demonstrated to play a crucial role in activating T1R3 TMD. The NHDC-docked model was then compared with a lactisole-docked inactive form, several residues were characterized as important for the recognition of NHDC; however, most of them were distinct from those of lactisole. Residues such as His6413.33 and Gln7947.38 were found to be oriented differently. This study provides useful information that will facilitate the design of sweeteners and inhibitors that interact with T1R3 TMD.

Published: September 2023

AbstractCurrently, clinical strategies for the treatment of wounds are limited, especially in terms of achieving rapid wound healing. In recent years, based on the technique of electrospinning (ES), cell electrospinning (C-ES) has been developed to better repair related tissues or organs (such as skin, fat and muscle) by encapsulating living cells in a microfiber or nanofiber environment and constructing 3D living fiber scaffolds. Therefore, C-ES has promising prospects for promoting wound healing. In this article, C-ES technology and its advantages, the differences between C-ES and traditional ES, the parameters suitable for maintaining cytoactivity, and material selection and design issues are summarized. In addition, we review the application of C-ES in the fields of biomaterials and cells. Finally, the limitations and improved methods of C-ES are discussed. In conclusion, the potential advantages, limitations and prospects of C-ES application in wound healing are presented.
