Published: December 2023

AbstractTetrabutylurea (TBU) is mainly used as a working liquid in the preparation of hydrogen peroxide via the anthraquinone process. It is reported that dibutylamine (A) reacts with dibutylcarbamyl chloride (B) to produce TBU in the presence of triphosgene, which is the decisive step of the reaction. In this study, we aimed to investigate the reaction kinetics of the decisive step to gain more insight into the reaction. The reaction order as well as the pre-exponential factors (A) and the activation energies (E
a) were determined. The kinetic study suggested that the total order of the reaction is second. E
a = 5.4 × 104 J/mol, A = 1.5257 × 107 L/(mol × min), calculated through a second-order kinetics model. The accuracy and applicability of the kinetic model were verified by serval experiments, showing that enhancing reaction temperature could shorten the reaction time and increase the conversion rate.

AbstractThe aim of this study was to gain an understanding of the evolving landscape of research on the intricate relationship between COVID-19 and livelihoods, while also identifying research gaps and directions. To achieve this aim, a systematic review methodology was adopted, and metadata was developed using VOSviewer and R software. A total of 1988 relevant articles on COVID-19 and livelihoods were collected since the outbreak of the pandemic. However, after applying exclusion criteria and conducting thorough reviews, only 1503 articles were deemed suitable for analysis. The data was analyzed in relation to three phases of COVID-19 impacts: the early stage of COVID, the middle stages during the outbreak, and the post-recovery phase. We examined the distribution of research disciplines, regions, authors, institutions, and keywords across these phases. The findings revealed that coping strategies, food security, public health, mental health, social vulnerability, and regional differences were extensively researched areas in relation to COVID-19 and livelihoods. It was found that the United States had the highest volume of research on COVID-19 and livelihoods. Additionally, the top 1.28% of journals published 18.76% of the literature, with a predominantly focused on the environmental category. This study offers valuable perspectives into the vulnerability caused by the COVID-19 pandemic and its impacts on livelihoods. Furthermore, it provides lessons learned, outlines potential future research pathways to understand the dynamics between environmental factors (like COVID-19) and livelihood stress, and includes a comparison of traditional livelihoods research.
The effects of war, displacement, and trauma on child development
Authors: Hazer Livia , Gredebäck Gustaf 
Published: December 2023

AbstractIn this paper, we review how refugee children’s psychological development is impacted by experiencing war, displacement, and trauma. As the Syrian conflict has resulted in the largest refugee crisis in modern history, we focus on Syrian refugees, but comparisons to other current major conflicts (Myanmar, Afghanistan, and Yemen) are done for reference, making this review relevant, not only for the Syrian conflict but war-affected children in general. The potentially traumatic events (PTEs) experienced by families and children vary depending on current and past migration experiences. During the premigration phase, there is a high risk of war-related PTEs whereas lack of shelter, high insecurity, and exploitation are common during the perimigration phase. Common PTEs during postmigration include uncertain legal status, changed family dynamics, downward mobility, and lack of social support. A high number of PTEs, low mental health, and permanent postmigration stress are evident across conflicts. In addition to these PTEs that impact all family members, there are additional long-lasting child-specific interpersonal PTEs related to parental practices and lack of support. These cumulative stressors are associated with poor mental health and developmental delays in several domains including cognitive functioning, emotion regulation, affective processing, and prospective control. At the same time, some studies demonstrate a high degree of resilience, and normative development, or report a lack of association between the psychological development of children and levels of PTEs. The number of studies assessing child development in this context is limited and more research is required in order to fill knowledge-gaps related to the mechanisms, and causal relations, behind these developmental outcomes.

Authors: Wang Xiaoxuan , Liu Jinrong 
Published: December 2023

AbstractDuring the Republican period, all fields of Chinese society were impacted by advanced Western ideas, society was exposed to numerous problems, and school education was incapable of assuming the responsibility of cultivating talents, so social education was highly emphasized. This study takes the policy decrees related to social education issued by the Ministry of Education from 1912 to 1945 as an entry point, and takes universities that promoted social education as a medium to explore the historical process of universities serving the society in the context of China’s political change and cultural integration. During the Republican period, social education was carried out under four different concepts, namely, common education, Civilian education, mass education, and anti-Japanese War Education, and universities played an active role in promoting the cause of social education. Studying the whole process of university social education from a historical macro perspective, it is found that it provides the opportunity for the out-of-school group to relearn and improves the level of popular culture and knowledge. At the same time, it provides valuable Chinese experience in building a learning society and realizing lifelong education worldwide, and is of practical significance to countries with similar problems.
Defect segmentation with local embedding in industrial 3D point clouds based on transformer
Authors: Jing Junfeng , Wang Huaqing 
Published: December 2023

Abstract
Three-dimensional (3D) defect detection provides an effective method for improving industrial production efficiency. However, the 3D dataset is scarce, which is valuable for the industrial production field. This study proposes a new approach for detecting defect point clouds, which can provide an end-to-end 3D defect detection model. A self-attention mechanism is used to enrich the semantic relationships between local neighborhood features and global features based on the connection between them. Through adding multi-channel features, the rich structural features of the target point cloud are obtained, and the defect areas are accurately segmented to finally complete the 3D point cloud defect detection task. Furthermore, the multi-feature fusion in the model makes the segmented defect regions closer to the ground truth. Our method outperforms four state-of-the-art point cloud segmentation methods in terms of both segmentation region accuracy and defect detection point cloud accuracy. In the field of 3D defect detection, it provides an effective method to detect 3D information of industrial products.
Multi-scale ultrasonic imaging of sub-surface concrete defects
Authors: Zhang Tonghao , Zhang Lu , Ozevin Didem , Attard Thomas 
Published: December 2023

Abstract
This paper introduces a new method for creating the ultrasonic image of concrete that utilizes both linear and nonlinear wave properties in a single measurement. Linear ultrasonic imaging relies on wave velocity. The resolution of linear ultrasonics for various inclusion sizes and inclusion-to-base material ratios is numerically and experimentally studied. The nonlinear ultrasonic testing (NLUT) image is based on the acoustic nonlinearity coefficient, calculated using inputs of the first and second harmonic amplitudes, wave number, and the distance between the transmitter and receiver. The ultrasonic waveform is decomposed into its harmonics using wavelet transform. Their wave velocities, wave numbers, and amplitudes are extracted to calculate the linear wave velocity and the acoustic nonlinearity coefficient. Four calibration samples with different inclusions are tested to evaluate the effectiveness of combining two imaging methods: pure concrete, concrete with small foam inserts simulating air inclusions, and two concrete samples with larger foam inclusions. The angle dependence of acoustic nonlinearity coefficient is shown. The results show that constructing both linear and nonlinear ultrasonic imaging is necessary when the defect’s properties are unknown.

Abstract
Understanding the electrical properties of ultra-high-performance concrete (UHPC) is of paramount importance in the realm of smart concrete as it unlocks the potential for creating advanced, intelligent, and resilient infrastructure systems. This study focused on systematically assessing the electrical behaviors of UHPC with two commonly-used reinforcing conductive fillers, i.e. carbon fibers (CFs) and steel fibers (SFs). The effects of fiber type, fiber length, fiber content, and curing age on the alternating current (AC) resistivities and AC electrochemical impedance spectroscopy (AC-EIS) spectra of fiber-reinforced UHPC were investigated, and the equivalent circuit models of fiber-reinforced UHPC were established. Experimental results showed that the AC resistivities of UHPC with CFs and with SFs both exhibited a faster growth rate during the 14–28 d of curing, but subsequently decelerated after the completion of hydration, and stabilized at 90–120 d. Compared with the control sample, the addition of both CFs and SFs resulted in a reduction of the electrical resistivity of UHPC, with a more pronounced decrease observed with higher fiber content. In particular, the addition of SFs demonstrated a more significant reduction in UHPC’s AC resistivity in relative to CFs, with the addition of 4 vol.% copper-plated end-hook SFs remarkably lowering the resistivity by up to 87.5%. Furthermore, the introduction of different types of fibers caused remarkably different AC-EIS topologies of UHPC. The proposed equivalent circuit models reveal that compared to the control sample, the introduction of fibers can provide the fiber-fiber conductive paths and fiber-wrapped hydration products (Q

Instead, if the parameters µ and p satisfy the opposite condition we have: (a) blow-up when the initial datum is large enough, (b) existence of global solutions when the initial datum is small enough. Hence our conditions on the parameters µ and p are optimal. We see that blow-up and global existence do not depend on the amplitude of the cone. This is very different from what happens in the Euclidean setting (Bandle and Levine 1989 Trans. Am. Math. Soc.

Authors: Ma Luosheng , Ma Lili , Chen Ming , Zhou Jilan , Feng Xinya , Jia Lei 
Published: December 2023

Abstract
ZK60 magnesium alloy was prepared by the hot-pressed sintering combined with the hot-extruded technique. The microstructure and mechanical properties evolution of ZK60 alloy with a reduced extrusion temperature from 350 °C to 250 °C were investigated in detailed. The extruded alloy was mainly composed of fine α-Mg grains and MgZn2 phase. The grains size gradually decreased with a reduction in extrusion temperature, and the yield strength obviously increased accordingly. The alloy extruded at 250 °C exhibited the smallest average grain size of 2.5 μm and the best combination of strength and plasticity, with a yield strength of 279 MPa and fracture strain of 18.1% in compressive condition, and 263 MPa and 13.7% in tensile condition, as well as a tension-compression yield asymmetry of 0.94. Both the fine grains formed by the continuous and twin induced dynamic crystallization mechanism and the precipitation strengthening contributed to the strength improvement.
Enabling attractive-repulsive potentials in binary-collision-approximation monte-carlo codes for ion-surface interactions
Authors: Drobny Jon T , Curreli Davide 
Published: December 2023

Abstract
Binary Collision Approximation (BCA) codes for ion-material interactions, such as SRIM, Tridyn, F-TRIDYN, and SDtrimSP, have historically been limited to screened Coulomb potentials even at low energies due to the difficulty in numerically solving the Distance of Closest Approach (DOCA) problem for attractive-repulsive potentials. Techniques such as direct n-body simulation or modifications to Newton’s method are either prohibitively costly or not guaranteed to work for all potentials. Advanced rootfinding techniques, such as companion matrix solvers, offer a solution. For many attractive-repulsive potentials, however, a companion matrix cannot be used directly, because there is no way to put the associated functions into a monomial basis form. A complementary technique is proxy rootfinding—by finding the best-fit polynomial approximant of a function, the zeros of the approximant can be guaranteed to be close to the zeros of the function. Using the Chebyshev basis and grid offers additional guarantees with regards to the quality of the approximation, the speed of convergence, and the avoidance of Runge’s phenomenon. By finding Chebyshev interpolants and using the Chebyshev-Frobenius companion matrix, the zeros of any real function on a bounded domain can be found. Here we show that using an Adaptive Chebyshev Proxy Rootfinder with Automatic Subdivision (ACPRAS) with appropriate scaling functions, numerical issues presented by attractive-repulsive potentials, including those of scale, can be handled. Using these techniques, we show that it is possible to include any physically reasonable interatomic potential in a BCA code, and to guarantee correctness of the resulting scattering angle calculations.

Abstract
Sustainable packaging solutions are of paramount importance in addressing the environmental challenges posed by conventional non-biodegradable materials. This study addresses this critical need by introducing a novel approach to crafting antimicrobial biodegradable polymer films. Leveraging the benefits of polyvinyl alcohol (PVA) as a base material, combined with corn-starch (CS) and mint extract (ME), these films offer a compelling synergy of eco-friendliness, antimicrobial efficacy, and mechanical strength. The antimicrobial property was imparted by adding mint extract, and boric acid (BA) was added as a cross-linker for better mechanical properties. All process was done by solution casting method followed by mechanical stirring. After 7 days, starch-PVA blend showed 50% weight loss; however, after adding mint extract, the action of microbes was reduced, and a 50% reduction in weight was observed after 12 days. The excellent mechanical properties were achieved by adding 10% aqueous solution of BA as a cross-linker. The confirmation of BA in the blend was done by the Fourier transform infrared spectroscopy (FTIR). Differential scanning calorimetry (DSC) was used to check the thermal properties of the films. Antimicrobial results showed that mint extract was resistant to staphylococcus aureus bacteria. These biodegradable films offer a multifaceted solution, aligning with sustainability objectives, showcasing antimicrobial potential, and demonstrating mechanical robustness. As such, they hold promise for a diverse array of applications, particularly in the realm of environmentally conscious food packaging. In the pursuit of greener alternatives, these films stand as a testament to innovative materials engineering that harmonizes functionality with ecological responsibility.

Abstract
Morphological changes can affect distribution of dose in patients. Determination of the dose distribution changes for each fraction radiotherapy can be done by relative in vivo dosimetry (IVD). This study analysed the distribution of doses per fraction based on the fluence map recorded by the electronic portal imaging device (EPID) of the patient’s transit dose. This research examined cases involving the cervix, breast, and nasopharynx. Transit dose analysis was performed by calculating the gamma index (GI) with composite and field-by-field methods. The gamma passing rate (GPR) value was assessed for its correlation with the subject’s body weight. In the case of the nasopharynx, breast, and cervix, the GPR value decreased as the fraction increased. In the case of the nasopharynx, the correlation between the GPR and fraction radiotherapy showed no difference when using either composite or field-by-field methods. However, in cases involving the cervix and breast, there was a difference in the correlation values between the composite and field-by-field methods, where the subject had a significant correlation (p < 0.05) when it was done using a field-by-field method. In addition, the nasopharynx had the highest number of subjects with significant correlation (p < 0.05) between GPR and body weight, followed by the cervix and breast. In the nasopharynx, breast, and cervix, the reproducibility of the dose distribution decreased. This decreased reproducibility was associated with changes in body weight.

Published: December 2023

Abstract
Non-Gaussian quantum states are a known necessary resource for reaching a quantum advantage and for violating Bell inequalities in continuous variable systems. As one kind of manifestation of quantum correlations, Einstein–Podolsky–Rosen steering enables verification of shared entanglement even when one of the subsystems is not characterized. However, how to detect and classify such an effect for non-Gaussian states is far from being well understood. Here, we present an efficient non-Gaussian steering criterion based on the high-order observables and conduct a systematic investigation into the hierarchy of non-Gaussian steering criteria. Moreover, we apply our criterion to three experimentally-relevant non-Gaussian states under realistic conditions and, in particular, propose a feasible scheme to create multi-component cat states with tunable size by performing a suitable high-order quadrature measurement on the steering party. Our work reveals the fundamental characteristics of non-Gaussianity and quantum correlations, and offers new insights to explore their applications in quantum information processing.
