Authors: Yu Liang , Huang Pengcheng 
Published: May 2023

Abstract
In order to realize the overall goal of energy saving and emission reduction in rural residential buildings and rural energy fields under the double-carbon goal and to promote the process of rural revitalization strategy, this paper analyzes the basic situation and existing problems of rural residential buildings, energy and other aspects by investigating and studying the basic situation of rural areas in Northeast China. The results show that the current rural residential buildings in Northeast China have been built for a long time, and the use of different rooms in the buildings is quite different, which greatly affects the indoor thermal environment and energy consumption under different heating forms. Rural heating equipment is more traditional, the utilization rate of clean energy is low, and there are some problems in the heating process, such as smoke pollution and uneven indoor temperature. The process of agricultural straw resource utilization is slow, and the problem of straw open burning is severe. Through the analysis and summary of the above problems, it will lay the foundation for the subsequent solution and improvement of rural residential buildings and energy problems in Northeast China.

Published: May 2023

Abstract
Constructing a unified Live-Virtual-Constructive (LVC) integrated simulation environment has always been a major goal in the modeling and simulation (M&S) field, and ensuring the time-space consistency is the foundation of its construction. That is, the inconsistency of time and space expression between integrated subsystems must be solved to achieve accurate and effective information interaction. To this end, this paper analyzes the specific causes of time-space inconsistency of LVC system, and gives the overall solution and the corresponding strategies or algorithms involved, including clock synchronization strategy, space coordinate conversion algorithm, time description conversion algorithm, dead reckoning (DR) algorithm and event causality control method. The relevant research has been verified in the integrated simulation system of missile attacking surface targets, and can provide technical support for the construction of large-scale LVC system.

Authors: Wang Dan , Hong Liang , Zhang Ce , Xiao Yong , Lin Ye 
Published: May 2023

Abstract
A multi-classifier target recognition algorithm based on fuzzy pattern recognition and fuzzy comprehensive evaluation theory is proposed, where the base classifiers are deployed as fuzzy pattern recognition classifiers, and the secondary classifiers are based on fuzzy comprehensive evaluation theory. On the basis of time-frequency domain analysis of target signals, fuzzy theories such as fuzzy pattern recognition, decision-making and comprehensive evaluation are synthetically applied to carry out first-level evaluation, where the extracted feature parameters are used as the input of target base classifiers. With the evaluation results as the input of second-level evaluation, target state recognition is performed on the multi-state human targets behind the walls in the ultra-wideband radar sensor network based on fuzzy evaluation. The results show that the recognition can efficiently discern the Multi-status human being behind the wall.

Authors: Yu Hailong 
Published: May 2023

Abstract
In this paper, a dual-polarized antenna with high isolation working at millimeter wave(mmW) frequency band is attempted. The proposed antenna can provide two orthogonal ports fed by only one square radiation patch with more than 30 dB isolation. In addition, the antenna can obtain a peal gain level of around 8dB for two ports. A more simple structure, which consists of two substrates and one foam layer rather than traditional two substrates, a cover plate and two foam layers, makes it more suitable for arrays form and easier for fabrication.

Authors: Liu Yaqiong , Zhou Zhi , Huang Ying 
Published: May 2023

AbstractDifferent development levels and speeds in different regions in China leads to the great difference in the allocation of rural water conservancy projects and the inefficiency. In order to improve the services function and configuration efficiency of rural China water conservancy infrastructure from water engineering, water supply engineering, reservoir engineering, the work chose the Chinese provincial panel data from 2017 to construct input-output indicator evaluation system with super-efficiency DEA. Then we designed the rural area of configuration of water conservancy projects for comparative analysis and China’s current rural water conservancy project region configuration system of geographical network coverage. Finally, based on the configuration in the grid lines, the method was proposed for efficiency. In order to analyze the regional difference in input-output efficiency of rural water conservancy construction, the panel data of 2017 was selected to establish the input-output indicator system of management efficiency. The results of super efficiency DEA show the general situation of input-output efficiency of rural water conservancy construction in China is not good, while there are some differences among input-output efficiency of rural water conservancy construction in East, West, Middle of China. Besides, Qinghai, Beijing, Hainan and Tibet are located in the last four. Finally, the four regions are all relatively effective with less than 100% super efficiency value, and four regions has redundant input in hydropower investment.

Abstract
In order to reduce the weight of the missile launch system and reduce the cost of missile launch, a flexible airbag ejection system is studied to realize the work on the missile. The working mechanism and ejection performance of the flexible airbag ejection system are studied through numerical calculation. The results show that the ejection performance of the flexible airbag ejection system is related to factors such as the type and temperature of the ejection medium. In the study of the ejection medium, it is found that: the smaller the molar mass of the ejection medium and the higher the temperature, the better the ejection performance of the flexible airbag ejection system. The research results can provide an important reference for the design and optimization of the flexible airbag ejection system.
Dynamics model and numerical simulation of single stage water rocket
Authors: Ding Shaozhe , Liu Longbin , Zhang Shifeng 
Published: May 2023

Abstract
The initial launch parameters of a water rocket have a significant impact on its speed, altitude and other flight performance. The dynamic model describing the mass, velocity, nozzle velocity and internal pressure of water rocket was established by the force analysis of its ascending stage. Numerical simulation was carried out on the movement process of the water rocket. The changes of the internal pressure and thrust of the rocket body, and the speed and height law of the rocket in the flight process under the conditions of the same initial internal pressure and different initial loading propellant liquid were studied respectively. The results show that, under the designed conditions, the change law of the thrust force is similar to the variation of the internal air pressure in the ascending stage, and the internal air pressure decreases to 45%~57% of the initial value at last. Setting the volume of the initial loaded liquid to 0.43 helps to increase the boost duration and improve the utilization of the initial pressure, in which case, the maximum velocity of the launch rocket is not affected, but will lead to a decrease in thrust size.The above results provide important technical support for the optimal design of single-stage or multistage water rocket, and have strong guiding significance for carrying out water rocket flight test.

Published: May 2023

Abstract
Meeting the United Nation’ Sustainable Development Goals (SDGs) calls for an integrative scientific approach, combining expertise, data, models and tools across many disciplines towards addressing sustainability challenges at various spatial and temporal scales. This holistic approach, while necessary, exacerbates the big data and computational challenges already faced by researchers. Many challenges in sustainability research can be tackled by harnessing the power of advanced cyberinfrastructure (CI). The objective of this paper is to highlight the key components and technologies of CI necessary for meeting the data and computational needs of the SDG research community. An overview of the CI ecosystem in the United States is provided with a specific focus on the investments made by academic institutions, government agencies and industry at national, regional, and local levels. Despite these investments, this paper identifies barriers to the adoption of CI in sustainability research that include, but are not limited to access to support structures; recruitment, retention and nurturing of an agile workforce; and lack of local infrastructure. Relevant CI components such as data, software, computational resources, and human-centered advances are discussed to explore how to resolve the barriers. The paper highlights multiple challenges in pursuing SDGs based on the outcomes of several expert meetings. These include multi-scale integration of data and domain-specific models, availability and usability of data, uncertainty quantification, mismatch between spatiotemporal scales at which decisions are made and the information generated from scientific analysis, and scientific reproducibility. We discuss ongoing and future research for bridging CI and SDGs to address these challenges.
Antibacterial activity of silver nanoparticles created by one step nanosecond Nd: YAG laser ablation in water
Authors: Hasan Susan , Khashan Khawla S , Hadi Aseel A 
Published: May 2023

Abstract
The pulsed laser ablation in liquid (PLAL) technique was used to successfully synthesise silver nanoparticles (Ag NPs). With the goal of controlling their size, a laser wavelength of 1064 nm was focused on the Ag bulk target immersed in distilled water in a glass vessel with different laser fluences. The effect of laser fluence, and thus Ag NPs concentration on the bacterial pathogenic was investigated. While the Fourier-transform infrared spectroscopy (FTIR) and x-ray diffraction (XRD) patterns confirm the presence of Ag NPs, UV–vis spectrophotometry revealed a significant absorption peak at around 405 nm, which is attributed to the obtained Ag NPs’ characteristic surface plasmon resonance (SPR) peak. The SPR peak shifted towards a shorter wavelength as the laser fluence was increased, indicating that the Ag NPs have reduced in size. The transmission electron microscopy and size distribution images of Ag NPs clearly showed the effects of laser fluence on size reduction of Ag NPs. Bacteria activity was effectively inhibited by the Ag NPs which are found to be more effective against Gram-negative (Escherichia coli) than Gram-positive strains (Streptococcus aureus). PLAL has proven to be an effective method for controlling the size of NPs, which can be used in a variety of applications.
Determination of wear resistance of nickel-carbide alloy coating by atmospheric plasma spray technique on 30MnB5 alloy steel used in cultivator blades
Authors: Dilay Yusuf 
Published: May 2023

Abstract
The wear that occurs during tillage in agricultural machinery shortens the material’s life and increases costs. This study investigated the microstructure and morphology of cultivator blades coated with atmospheric plasma spray (APS) process and tested under real field conditions using OM, SEM, EDX, and XRD techniques. Abrasion tests were conducted in an area of 110 hectares and under two different soil moisture conditions. Material properties were investigated using hardness and surface roughness tests. The coating process was successful both mechanically and metallurgically by applying Ni-WC ceramic-metal (cermet) powder on the surface of 30MnB5 steel substrate with APS. The oxide and carbide structures detected on the coating surface by XRD studies resulted in a 1.5 times higher coating hardness. Due to the hard carbide phases in the coating matrix, the grooves on the wear surfaces were shallow and narrow compared to the substrate sample. The surface roughness values of the coated sample were approximately two times higher than the substrate sample. Due to the microstructure and high hardness, the coated specimen experienced three times less abrasion in both humidity conditions. The APS method can be successfully applied to the machined parts of tillage machines. In the near future, the cost of agricultural production can be reduced, and the environment can benefit from this method. In conclusion, this study presents a feasible approach to improving the wear resistance of Ni-WC ceramic-metal alloy by plasma spray coating under real field conditions.
Ag-doped CrN coating towards exhibiting excellent tribological and electrical properties under current-carrying friction
Authors: Hao Wu , Yanqiu Xia , Zhengfeng Cao , Lining Wu 
Published: May 2023

Abstract
In order to obtain sliding electrical contact materials with good conductivity and wear resistance, a series of silver doped chromium nitride (CrN-Ag) coatings were prepared by magnetron sputtering. The hardness, elastic modulus, chemical composition and surface morphology of the prepared coatings were characterized in detail. The tribological properties and conductivities of the prepared CrN-Ag coatings were investigated in detail at low and high current densities. The worn surfaces after friction test were also investigated to explore the lubrication mechanisms. The results show that the addition of Ag element could regulate the hardness, elastic modulus, chemical composition and surface morphology of the coatings. The CrN-Ag coating with 23 wt% Ag content exhibited the best conductive and tribological properties under low and high current densities. The analysis of friction surface shows that the conductivity and wear resistance of different coatings were mainly related to the Ag content of coatings.
Ammonium phosphotungstate nanoparticle/ultrathin g-C3N4 composite photocatalysts with Z-scheme heterojunctions: preparation and application to organic contaminant degradation
Authors: Li Pengxi , Liu Zhonghong , Tu Sheng , Jiang Wenming , Yang Jingjing 
Published: May 2023

Abstract
Owing to their advantageous physical, chemical, electronic, and optical properties, two-dimensional (2D) materials are widely used as highly active visible-light photocatalysts. In this study, 3D/2D composite photocatalysts were prepared from ammonium phosphotungstate nanoparticles and 2D ultrathin graphitic carbon nitride by an impregnation method and were found to efficiently promote the photodegradation of rhodamine B and tetracycline in water under visible light irradiation. Photocatalytic degradation was maximum at a PW12NH4 loading of 20 wt% (UCN20), with photodegradation efficiencies of 93.40% and 69.6% for RhB and TC, respectively. The photocatalytic degradation rate using UCN20 was 5.8-fold higher for RhB and 2.2-fold higher for TC compared to those with UCN. This high performance is ascribed to the large specific surface areas and pore volumes of the composites and the reduced probability of photogenerated carrier recombination therein. The related degradation mechanism is believed to involve a Z-scheme charge transfer mode, which enhances the redox capability of composite photocatalysts and renders them suitable for the visible light-driven remediation of wastewater containing organic contaminants.

Preprint Highlight: mRNA Location and Translation Rate Determine Protein Targeting to Dual Destinations
Authors: Mantegazza Adriana R. 
Published: May 2023

NET1 is a guanine nucleotide exchange factor for RhoA GTPase that plays different roles in the nucleus and cytoplasm. While perinuclear and peripheral mRNA translation sites have been identified, the mechanisms of spatial translation regulation and impacts on protein function are not generally understood. Here, the authors use genetic tools to manipulate NET1 mRNA targeting sequences, as well as proximity ligation, mass spectrometry, and imaging. They show that mRNA localization, translation rate, and the order of appearance of targeting domains during translation determine the extent of protein synthesis in each location, promoting site-specific NET1 function. This novel regulation of protein targeting by RNA translation rate and location uncovers the potential to engineer mRNA localization to optimize protein function and will likely impact research on cell biology, immunology, and beyond.

Preprint Highlight: Contractile ring mechanosensation and its anillin-dependent tuning during early embryogenesis
Authors: Landino Jennifer 
Published: May 2023

Dividing cells assemble and constrict a contractile ring made up of actin and myosin anchored to the cell cortex. How the contractile ring senses the mechanics of the cell cortex is not known. With asymmetric ring closure in C. elegans as a model, the authors used novel 4D imaging and image segmentation methods to carefully track ring closure over time. They found that ring-directed cortical flow underlies mechanosensation and supports a positive feedback loop between ring closure, cortical flow, and myosin accumulation. These findings suggest that differences in cell cortex stiffness may determine the orientation and type of cell division–i.e., asymmetric vs. symmetric ring closure. As tissue morphogenesis often relies on specifically oriented cell divisions, defining mechanisms of ring closure is essential for understanding multicellular development.

Phen2Disease: a phenotype-driven model for disease and gene prioritization by bidirectional maximum matching semantic similarities
Authors: Zhai Weiqi , Huang Xiaodi , Shen Nan , Zhu Shanfeng 
Published: May 2023

Abstract
Human Phenotype Ontology (HPO)-based approaches have gained popularity in recent times as a tool for genomic diagnostics of rare diseases. However, these approaches do not make full use of the available information on disease and patient phenotypes. We present a new method called Phen2Disease, which utilizes the bidirectional maximum matching semantic similarity between two phenotype sets of patients and diseases to prioritize diseases and genes. Our comprehensive experiments have been conducted on six real data cohorts with 2051 cases (Cohort 1, n = 384; Cohort 2, n = 281; Cohort 3, n = 185; Cohort 4, n = 784; Cohort 5, n = 208; and Cohort 6, n = 209) and two simulated data cohorts with 1000 cases. The results of the experiments showed that Phen2Disease outperforms the three state-of-the-art methods when only phenotype information and HPO knowledge base are used, particularly in cohorts with fewer average numbers of HPO terms. We also observed that patients with higher information content scores have more specific information, leading to more accurate predictions. Moreover, Phen2Disease provides high interpretability with ranked diseases and patient HPO terms presented. Our method provides a novel approach to utilizing phenotype data for genomic diagnostics of rare diseases, with potential for clinical impact.

Gangs and the Gig Economy: Triads, Precarity and Illicit Work in Hong Kong
Authors: Fraser Alistair , Joe-Laidler Karen 
Published: May 2023

Abstract
Paid employment in the criminal economy is, in many ways, the essence of precarious labour yet to date criminological work on the so-called ‘gig economy’ is scarce. Here we apply emergent sociological literature on ‘post-Fordist’ working cultures to precarious youth employment in Hong Kong, arguing: (1) recent reorganizations of labour markets towards flexible entrepreneurship are mirrored in the illicit economy; (2) a shift in structural features of triad gangs has led to a parallel form of ‘network sociality’; and (3) triad-affiliated youth remained rooted in place-based ‘communities of practice’ that form a point of difference from existing theory. In concluding, we reflect on the implications of these arguments for the study of illicit economies, triads and post-Fordist working cultures.
