Listen: a litho-phonic encounter
Authors: Smith Serena 
Published: June 2023

AbstractWorkshop manuals on lithography tend to be written with art students in mind and the information they contain largely focuses on technical aspects of the process. It is, however, difficult to put into words the nuances of this printmaking practice, and consequently, handbooks rarely refer to sensory information and phenomenological experience. In light of this issue, my intention in Listen is to test the potential and limitations of written language as a means through which to describe the tacit and embodied knowledge of a lithographer. To aid this task, I created a two-minute video recording of myself preparing a lithography stone and this video features as a central element in the text. Prompted by a process of transcribing its sound, this video became the protagonist of a transdisciplinary encounter between lithographic sound and words. Structured as an intertextual narrative, Listen couples the transcription of the video with a historic, geological and cultural survey of sonorous stones. Punctuating the dialogue, are quotations from lithography handbooks that tether this serendipitous exchange to its intention: that being to speak about the perceptual realms of lithographic practice. At the core of Listen, is the subject of graining limestone—a process that requires both careful attention, to ensure that the surface is even and free from unwanted marks, and a tolerant sensitivity to the abrasive noise of graining stone. These two aspects, attention and noise, are entwined in the content, critical interests, and metaphorical dimensions of Listen. As a piece of written material from ongoing practice-led research that explores the intersection between lithography and language, Listen knowingly tests the protocols of academic language. My intention through this unconventional approach, is not to present the results of an enquiry, but to offer the reader a scriptural space for contemplative reflection. Somewhat akin to the practices of stone lithography, I suggest that the act of engagement that Listen proposes is rewarded by intimate attention and sensitivity to the presence of noise.
Soil decontamination by natural minerals: a comparison study of chalcopyrite and pyrite
Authors: Wu Yanhua , Li Yuchan , Wang Hong 
Published: June 2023

Environmental context With the rapid pace of industrialisation and urbanisation, soil contamination by organic pollutants has become a global focus of concern due to its serious threat to ecosystems and human health. Although a myriad of synthetic catalysts have been developed, natural minerals have the potential to be developed into cost-effective, environmentally benign and efficient catalysts to decontaminate soil. The efficient performance of natural minerals demonstrated in this study indicates a potential for their utilisation in the removal of refractory organic pollutants in soil. Rationale Organic pollution of soil has raised worldwide concern owing to the potential effects on ecosystems and human health. Natural metal minerals rich in transition metal elements have the potential to be developed into environmentally benign activators of peroxymonosulfate (PMS) and hydrogen peroxide (H2O2) for soil decontamination. Methodology A comparison study employing natural chalcopyrite (NCP) and natural pyrite (NP) as activators in the combined Fenton-like systems of PMS and H2O2 to degrade organic pollutants in soil has been carried out. Tetracycline hydrochloride (TCH) and phenanthrene (PHE) were selected as representatives of widely existing contaminants, antibiotics and polycyclic aromatic hydrocarbons, in the study. Key parameters including initial pH, catalyst and oxidants dosage were also optimised. Results A total organic carbon (TOC) removal efficiency of 68.66% was achieved for TCH (500 mg kg–1) with the addition of 0.75 g L–1 NCP, 1.23 mM PMS and 1.23 mM H2O2 within 4 h, whereas a slightly lower mineralisation efficiency of 64.78% was obtained by the NP heterogeneous system. For PHE (50 mg kg–1), 93.04% of TOC was removed using a NCP/PMS/H2O2 process, which was much higher than that of NP (45.76%) after 24 h. The quenching experiments indicated that ˙OH prevailed over SO4˙−EN22116_IE1.gif, and ˙O2−EN22116_IE2.gif also played a vital role in the PMS/H2O2 coupling process. Discussion The more superior performance of NCP has been elucidated via X-ray photoelectron spectroscoy analysis and comparison of catalytic mechanisms. The existence of Cu+ played an important role in the transformation of Fe3+ to Fe2+ and facilitated the continuous generation of active radicals. A possible degradation pathway was proposed based on the intermediates identified by GC-MS analysis. We anticipate this study would provide implications for the utilisation of natural minerals in the removal of refractory organic pollutants in soil.
Pervasive RNA folding is crucial for narnavirus genome maintenance

Published: June 2023

A synthetic biology approach toward constructing an RNA-based genome expands our understanding of living things and opens avenues for technological advancement. For the precise design of an artificial RNA replicon either from scratch or based on a natural RNA replicon, understanding structure–function relationships of RNA sequences is critical. However, our knowledge remains limited to a few particular structural elements intensively studied so far. Here, we conducted a series of site-directed mutagenesis studies of yeast narnaviruses ScNV20S and ScNV23S, perhaps the simplest natural autonomous RNA replicons, to identify RNA elements required for maintenance and replication. RNA structure disruption corresponding to various portions of the entire narnavirus genome suggests that pervasive RNA folding, in addition to the precise secondary structure of genome termini, is essential for maintenance of the RNA replicon in vivo. Computational RNA structure analyses suggest that this scenario likely applies to other “narna-like" viruses. This finding implies selective pressure on these simplest autonomous natural RNA replicons to fold into a unique structure that acquires both thermodynamic and biological stability. We propose the importance of pervasive RNA folding for the design of RNA replicons that could serve as a platform for in vivo continuous evolution as well as an interesting model to study the origin of life.

Published: June 2023

Abstract
A comprehensive study of favoured and unfavoured α-decay, cluster decay, weak-decay along with spontaneous fission in undetected superheavy nuclei within the range for proton number 111 ≤ Z ≤118 and neutron number 161 ≤ N ≤192 is performed. Half-lives for various mentioned decays are estimated with good accuracy on the basis of NUBASE2020 and are found in excellent match with the known half-lives. α-decay mode is found most probable in this wide range and correspondingly potential α-decay chains are reckoned. Peculiarly, the chances of cluster emission, as well as weak-decay, are also anticipated in this region of the periodic chart which open new pathways of detection of superheavy nuclei.
Revisiting Vainshtein screening for fast N-body simulations
Authors: Brando Guilherme , Koyama Kazuya , Winther Hans A. 
Published: June 2023

AbstractWe revisit a method to incorporate the Vainshtein screening mechanism inN-body simulations proposed by R. Scoccimarro in [1]. We further extend this method to cover a subset of Horndeski theories that evade the bound on the speed of gravitational waves set by the binary neutron star merger GW170817. The procedure consists of the computation of an effective gravitational coupling that is timeandscale dependent,Geff(k,z), where the scale dependence will incorporate the screening of the fifth-force. This is a fast procedure that when contrasted to the alternative of solving the full equation of motion for the scalar field insideN-body codes, reduces considerably the computational time and complexity required to run simulations. To test the validity of this approach in the non-linear regime, we have implemented it in a COmoving Lagrangian Approximation (COLA)N-body code, and ran simulations for two gravity models that have fullN-body simulation outputs available in the literature, nDGP and Cubic Galileon. We validate the combination of the COLA method with this implementation of the Vainshtein mechanism with fullN-body simulations for predicting the boost function: the ratio between the modified gravity non-linear matter power spectrum and its General Relativity counterpart. This quantity is of great importance for building emulators in beyond-ΛCDM models, and we find that the method described in this work has an agreement of below 2% for scales down tok≈ 3h/Mpc with respect to fullN-body simulations.

Abstract
We show that in optical clocks based on Rabi interrogation, both laser-frequency and magnetic-field flicker (

) noise with zero mean can lead to servo errors at the 10−18 level if the negative-detuning (red) and positive-detuning (blue) sides of the transition are always probed in the same order. This is due to the strong correlations of flicker noise in combination with an imbalance in the response of the servo discriminator to positive and negative differential frequency noise between the red- and blue-side probing. This imbalance is particularly large for a normalized discriminator. We derive an analytical expression for the servo error based on the correlation function of the laser-frequency or magnetic-field noise and compare it to numerical servo simulations to demonstrate how the error depends on the noise level, servo parameters, and probing sequence. We also show that the servo error can be avoided by normalizing the discriminator with a moving mean or by reversing the red/blue probing order for every second servo cycle.
A novel brain source reconstruction using a multivariate mode decomposition

Published: June 2023

Abstract

Objective. Brain source reconstruction through electroencephalogram is a challenging issue in brain research with possible applications in cognitive science as well as brain damage and dysfunction recognition. Its goal is to estimate the location of each source in the brain along with the signal being produced. Approach. In this paper, by assuming a small number of band limited sources, we propose a novel method for the problem by using successive multivariate variational mode decomposition (SMVMD). Our new method can be considered as a blind source estimation method, which means that it is capable of extracting the source signal without the knowledge of the location of the source or its lead field vector. In addition, the source location can be determined through comparing the mixing vector found in SMVMD and the lead filed vectors of the entire brain. Main results. The simulations verify that our method leads to performance improvement in comparison to the well-known localization and source signal estimation techniques such as MUltiple SIgnal Calssification (MUSIC), recursively applied and projected MUSIC, dipole fitting method, MV beamformer, and standardized low-resolution brain electromagnetic tomography. Significance. The proposed method enjoys low computational complexity. Moreover, our investigations on some experimental epileptic data confirm its superiority over the MUSIC method in the aspect of localization accuracy.

Published: June 2023

Abstract
The effects of varied contents of Ni (1.2 wt.%, 1.6 wt.%) and Fe (0.6 wt.%, 0.8 wt.%) on the microstructure and high temperature mechanical properties of Al-Si alloy were studied using scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS) and tensile testing machine. The experimental results demonstrate that Ni element plays a crucial role in modifying the Fe-rich phase type, morphology and distribution in the Al-Si alloy. The addition of 1.2 wt.% Ni and 0.6 wt.% Fe could generate a Chinese script Fe-rich strengthening phase in Al-Si alloy. Further increasing to 1.6 wt.% Ni and 0.8 wt.% Fe, the long needle-shape Fe-rich phase was detected. High temperature tensile properties of the alloy were significantly improved, because of the Chinese script Fe-rich strengthening phase in the Al-Si alloy containing 1.2 wt.% Ni and 0.6 wt.% Fe. The ultimate tensile strength (UTS) of Al-Si alloy with 1.2 wt.%Ni-0.6 wt.% Fe is up to 229 MPa, 174 MPa and 139 MPa at 250 °C, 300 °C and 350 °C, respectively.

Published: June 2023

Abstract
Aggregate dispersion is one of the main diseases of porous asphalt. Reasonable material composition can effectively reduce the occurrence of dispersion disease. In order to study how to determine the volume index and mechanical properties of the mixture from the five aspects of asphalt, asphalt oil film thickness, coarse aggregate, fiber and filler, this paper selects different kinds of materials and different additions, based on the benchmark mix ratio, and carries out the Kentucky dispersion test to reduce the dispersion disease of the porous asphalt. Through the analysis of the test results, it is verified that adopting high-viscosity modified asphalt, increasing the thickness of asphalt oil film, adding lime or hydrated lime as filler, and adding a certain amount of fiber can enhance the anti-flying performance of porous asphalt mixture. At the same time, the article carries out experimental analysis of various additives for different materials. Finally, various material comparison schemes to improve the anti-flying performance of porous asphalt mixture were formed. In terms of the selection and use of raw materials, it provides certain guidance for the construction of porous asphalt.

Authors: He Kuiliang , Zheng Jianfei , Xin Li 
Published: June 2023

Abstract
Due to the lack of research on the applicability and optimization design of low freezing point asphalt mixtures in specific environments, especially for the harsh environments of low freezing point asphalt mixtures in mountainous areas during cold winter and high humidity in other seasons, there is a significant engineering demand. This paper carries out a study on the performance optimization design of low freezing point asphalt mixtures in northern mountainous areas. Through comparative analysis of low freezing point asphalt mixture technologies and analysis of the road performance of low freezing point asphalt mixtures, combined with the climate and driving characteristics of northern mountainous areas, the low freezing point asphalt mixture suitable for northern mountainous areas is selected. The research shows that the hygroscopicity of M low freezing point filler is significantly stronger than that of Z low freezing point filler, and since the humidity in northern mountainous areas is relatively high, selecting low freezing point fillers with lower hygroscopicity to prepare low freezing point asphalt mixtures can avoid safety accidents caused by excessively wet road surfaces. SBS modified asphalt and waste tire rubber powder modified asphalt can both produce low freezing point asphalt mixtures that meet the requirements of standard road performance, and both have good high and low temperature performance. When conditions permit, waste tire rubber powder modified asphalt low freezing point asphalt mixture is recommended as the first choice.

Published: June 2023

Abstract
Carbon fiber reinforced polymer (CFRP) with high specific strength, specific modulus, and other outstanding properties, which could be used in aerospace, shipbuilding, and railway. The joint of carbon fiber composite material plate and metal material plate plays an important role in the overall performance of the structure. In this paper, a carbon fiber reinforced polymer (CFRP) progressive damage model is developed based on composite laminate theory and 3D Hashian theory. The model of the double bolt single lap joint shear connection is established for the CFRP plate and the finite element method is used to carry out the stress analysis and failure prediction of the lap structure. The effect on structural performance under tensile conditions was studied through the change of double bolt spacing. The results show that the decrease in bolt row spacing can lead to the interference effect between holes. In addition, the progressive damage of the composite plate is located near the center line of the bolt hole.

Abstract
Ultra-fine 2,2’,4,4’,6,6’- Hexanitrostilbene (HNS-IV) was obtained by HNS-II by vibration cavity comminute. This method uses only alcohol and deionized water, which can be viewed as a green technology. The morphology, particle size, specific surface area, thermal decomposition property and the threshold energy for slapper detonator were compared between HNS-IV and HNS-II in this paper. Results show that after HNS pulverizing, the particle size decreased from 27.18μm to 1.44μm, the specific surface area increased from 0.73m2•g−1 to 9.10m2•g−1. DSC analysis shows that the decomposition peak temperature Td decreases and the melting temperature Tm increases after pulverizing. It is speculated that in the explosive reaction with very high heating rate, the enthalpy of decomposition will be increased by pulverizing, which will be more conducive to detonation growth and explosive reaction. According to the calculation of thermal decomposition kinetics, the decomposition and activation energy Ea of HNS decreases after pulverizing, and the thermal decomposition reaction rate of HNS-IV increases when the temperature is less than 409.6°C. The initiation threshold test of the impact plate shows that the 50% initiation threshold energy of HNS- II is 1.242J, and the 50% initiation threshold energy of HNS-IV is 0.558J, and the initiation threshold for slapper detonatorer is significantly reduced by 55%. This means that the ultra-fine HNS-IV is very suitable as the main ingredient in the booster in the EFI initiation.

Published: June 2023

Abstract
In order to study the effects of graphite and carbon fiber on the strength and conductivity of concrete, the compressive strength and conductivity of three types of composite concrete with different mixing ratios of graphite, glueless fiber and rubberized carbon fiber were tested. The results show that the strength of 5000 mesh graphite is weakened, but the ability to reduce resistivity is improved, and the resistivity can be stabilized at about 10 Ω·m. The performance of glue-free carbon fiber in concrete is better than rubberized carbon fiber. Carbon fiber can significantly change the electrical conductivity of concrete without significantly affecting the compressive strength of concrete. In the experiment, the best mixing ratio of concrete was cement 600 kg/m3, water-binder ratio 0.56, and 12mm glue-free carbon fiber content 0.89%. The 28d compressive strength is 36.4 MPa and the resistivity is 12.8 Ω·m.

The accuracy of the theoretical results is verified by model tests. According to the installation form of the helicopter reducer, the structure of the dual-frequency vibration isolation system is preliminarily optimized, which provides technical support for the design of the vibration isolator of the helicopter with variable speed.

Authors: Wang Ying , Zhang Yan , Li Jinmao , Song Chunlian 
Published: June 2023

Abstract
The random forest algorithm was used to analyze the degree of influence of four variables, namely, voltage, current, main gas flow rate, and powder feed, on the temperature of the plasma jet zone of the DC arc graphite purification. The BP algorithm was then used to build a network prediction model. After the training of the network, the validity of the model was verified by comparing the measured temperature values with the predicted results. From the results, it can be seen that the relative error of the prediction results is between -0.3 %and +0.3%, which proves that the built BP neural network temperature model has a satisfactory prediction effect. In addition, this paper also derives specific mathematical expressions based on the threshold and weight values of this temperature prediction model, which can be used to fit the temperature variation curve in the plasma jet region.
