Authors: Zhang Chunfeng , Zhu Baoguo , Meng Qingying , Wang Nannan , Feng Haoyuan , Araya Ken 
Published: July 2024

AbstractIn this paper, a three-stage subsoil interval mixing four-gang plough (TSIMF) was manufactured to enhance the property of planosol soil in 2016. The working width is set to 2 m to obtain a low operation cost. The total draught of the TSIMF was about 100 kN, the running resistance of the tractor included. The traction force (draught) of TSIMF was determined and the soil condition improved with the TSIMF was discussed. A field test of soybean with TSIMF showed that the soil moisture was about 2% volume greater than that in the CK (subsoiler) field. The soil temperature with the TSIMF was about 1 ºC greater than the CK in the plowed layer, and the yield was 120% of the treatment of the CK. Sanjiang Plain is one of the most important commodity grain bases in China, and the albic soil accounts for about 25% of the total cultivated land. Improving the property of the albic farming land attaches great significance to the stability and increase of national grain production.

Authors: Zhang Yaping , Zhang Yong , Xue Dongdong , Zhou Shangyou , Zhang Mingshan , Wen Hao 
Published: July 2024

AbstractAs a widely used structural element in construction projects, pile foundations have been subject to varying degrees of damage during major earthquakes, especially in liquefiable sites. In order to study the effects of liquefaction on pile foundations under seismic conditions, this paper relies on an actual engineering case of the Xiong’an New Area to Beijing Daxing International Airport Express Line. A numerical model of the dynamic response of pile foundations in liquefied sites under seismic actions is established using the finite difference software FLAC3D. A comparative analysis is conducted between liquefied and non-liquefied sites. The results indicate that compared to non-liquefied sites, liquefaction of the site increases the bending moment on the pile shaft, with increased values for both the maximum bending moment and axial force. The main locations where pile damage may occur are determined. Although the influence of liquefaction on the axial force of pile foundations is relatively small, overall, liquefaction has a significant impact on pile foundations, reducing their bearing capacity.
Research on the Influence of Tunnel Invert Excavation on the Rheological Deformation of Different Levels of Surrounding Rock

Published: July 2024

AbstractThe surrounding rock in the closed section of the inverted arch creates a bearing ring that, when combined with the upper initial support, provides stable initial support. However, excavation of the inverted arch can disrupt the original balance and significantly impact the tunnel’s stability. Using the classic Burgers creep constitutive model, we conducted numerical analyses of the construction process for tunnels with different closure and exposure distances of the inverted arch under varying levels of surrounding rock, using the three-step excavation method. We compared the maximum displacement of the arch crown to study the influence of the closure and exposure distances of the inverted arch on the stability of the initial support lining. Our results show that the displacement of the arch crown is primarily influenced by the strength of the surrounding rock; the lower the strength of the rock, the greater the displacement of the arch crown. Furthermore, the displacement of the arch crown increases as the closure distance of the inverted arch increases. Conversely, the exposure distance of the inverted arch has a minimal impact on arch displacement, and the longer the exposure distance, the greater the arch displacement. These findings can serve as a foundation for improving existing standards and adapting them to the spatial requirements of large-scale mechanized operations.

Published: July 2024

AbstractIn order to enhance the blast resistance capabilities of critical structural elements in buildings, a blast-resistant honeycomb sandwich protective structure based on a negative Poisson’s ratio structure was proposed and designed. The failure mechanisms of the protective structure under distributed impulse loads were investigated. The structural parameters of the protective structure were optimized using the response surface methodology, and simulation analysis was conducted using the finite element method. The results demonstrate that the optimized negative Poisson’s ratio honeycomb sandwich protective structure exhibits excellent blast resistance performance.

Authors: Zhou Jie , Mou Haowen , Gao Junchao , Chang Xueping 
Published: July 2024

AbstractThe axially moving functionally graded pipe is widely used in many fields of industry, and its vibration and stability analysis is the key to its design. In this paper, the vibration characteristics and stability of functionally graded pipes with axial motion are analyzed. Based on the extended Hamilton variational principle, the dynamic equation of the pipe with internal flow velocity, material volume fraction index and axial velocity is established. The modified Galerkin method is used to solve the dynamic equation. The influence of the internal flow velocity, material volume fraction index, axial velocity and acceleration on the dynamic characteristics and stability of the system is analyzed. The characteristic curves of volume fraction index, axial velocity, acceleration and natural frequency are given. The results show that the natural frequency and critical velocity of the system increase with the increase of volume fraction index, and the designed volume fraction index can adjust the natural frequency of FGM pipeline system. When the system has axial acceleration, the greater the acceleration, the system will reach the critical value of axial instability in a short time.

Authors: Ee Ooi Chin , Vafaei Mohammadreza , Alih Sophia C. 
Published: July 2024

AbstractThe lumped plasticity model has been widely used for the nonlinear analysis of structures due to its simplicity, established guideline in seismic design codes, and less computational effort. However, it has been shown that the accuracy of the lumped plasticity model depends significantly on the plastic hinges’ properties. In this study, the nonlinear behaviors of two similar RC frames but with two different reinforcing detailing were simulated using the lumped plasticity model and the results were compared with those obtained from the conducted experiments on the frames. The effects of using two different plastic hinge models (i.e., ASCE/SEI 41–17 and moment-curvature) and effective stiffness values (i.e. ASCE/SEI 41–17 and Eurocode 8) were investigated. It was observed that the employed plastic hinge models had insignificant effect on the frames’ ultimate loads and both were able to estimate the ultimate loads accurately. However, the models underestimated the displacements corresponding to the ultimate loads of the frames. The failure modes of the frames were also estimated accurately.
Expansive Soil Subgrade: Soil Treatment Using Waste Ceramic Dust and Cement
Authors: Oruabena Bernard , Elechi Okoh 
Published: July 2024

AbstractThis study examines the potential application of leftover ceramic dust for stabilising expansive soil in infrastructure projects. We know that expansive soils have low strength and bearing capacity, which makes them troublesome in the natural world. Therefore, it’s crucial to level off weak or powerless soil to increase the sublevel’s bearing limit and support a suitable, long-lasting wearing course. To stabilise the soil, the poor soil was taken from Yenagoa, Bayelsa state in the South-South region of Nigeria, and mixed with varying amounts of waste ceramic dust. Standard Proctor compaction, soaked/unsoaked CBR testing, unconfined compressive strength tests, and consistency limit tests were used to evaluate the applicability of stabilised soil. The OMC appreciated at 7.5% of CD, which was utilized as an additive at 17.9 KN/m2, according to the results. From 1.72 to 1.74 KN/m2, MDD increased. From 9.3% at 0% to 16.77% (unsoaked) at 10% admixture (WCD + PLC) and 2.60% at 0%, according to the CBR test results, there was a rise. The highest (CBR) value was obtained when the mixture was soaked to 11.52%, as opposed to 16.77% when it was unsoaked. It was revealed that stabilisation in UCS improved with replacement ratios of 2.5%, 5%, 7.5%, and 10%, in that order. In conclusion, it was found that expanding soil stabilisation can be achieved without failure by using the ideal mix design.

Published: July 2024

AbstractWith the development of large span bridges, the height of the pylon is getting higher and higher, and the cross-sectional form of the pylon is getting more and more complicated, the construction of the pylon is a high-risk operation. The traditional pylon reinforcement construction uses manual asembling on the pylon, which is a labor-intensive high-altitude operation with high labor intensity, low construction efficiency, and not easy to guarantee quality. The pylon of Yanji Yangtze River Bridge is in the form of an octagonal outer cavity with a circular cross section, and the main reinforcement is arranged in four layers from outside to inside. The maximum diameter of the outer main reinforcement is 50 mm, the outer two layers and the third layer main reinforcement are connected by hoop reinforcement, and staggered arrangement of height directions. Based on the construction of the pylon of Yanji Yangtze River Bridge, the research on the construction technology of reinforcement bar was carried out for the characteristics of the pylon reinforcement, which solved the technical problems such as assembling of reinforcement parts, overall lifting and alignment docking on the pylon, which greatly reduced the labor intensity of operators, reduced the safety risk of overhead work and improved the quality of the pylon construction.

Published: July 2024

AbstractIn order to improve the contribution of prefabricated buildings in the field of reducing carbon emissions, a hemispherical prefabricated cavity intima structure was designed based on the prefabricated laminated floor technology, which is more in line with the development law of mechanics. From the mechanical properties and thermal properties as the research objects, the full size static loading test and the thermal test of the test house are used as the research methods, and the deflection deformation data of the cavity structure under different loading conditions and the temperature change data of the test house under different external temperatures are obtained. The final result verifies that the fabricated cavity structure has sufficient structural safety from the mechanical properties. Its performance in terms of thermal performance also proves that the prefabricated structure can maintain the thermal insulation capacity similar to that of the concrete structure with thermal insulation layer without any thermal insulation material. It provides theoretical support for further promoting the development of cavity structure.

Probing bad theories with the dualization algorithm. Part II.
Authors: Giacomelli Simone , Hwang Chiung , Marino Fabio , Pasquetti Sara , Sacchi Matteo 
Published: July 2024

Abstract
We continue our analysis of bad theories initiated in [1], focusing on quiver theories with bad unitary and special unitary gauge groups in three dimensions. By extending the dualization algorithm we prove that the partition function of bad linear quivers can be written as a distribution, given by a sum of terms involving a product of delta functions times the partition function of a good quiver theory. We describe in detail the good quiver theories appearing in the partition function of the bad theory and discuss the brane interpretation of our result. We also discuss in detail the lift of these theories to 4d quivers with symplectic gauge groups, in which our results can be recovered by studying the Higgsing triggered by the expectation value for certain chiral operators. The paper is accompanied by a Mathematica file which implements the algorithm for an arbitrary unitary bad linear quiver.
Scalar dark matter explanation of the excess in the Belle II B+ → K++ invisible measurement
Authors: He Xiao-Gang , Ma Xiao-Dong , Schmidt Michael A. , Valencia German , Volkas Raymond R. 
Published: July 2024

Abstract
Recently Belle II reported the first measurement of B+ → K+ + invisible(inv), which is 2.7σ above the standard model (SM) prediction. If confirmed, this calls for new physics beyond SM. In the SM, the invisible particles are neutrino-anti-neutrino pairs. There are more possibilities when going beyond the SM. In this work, we focus on decays to dark matter (DM) and show that the B → K + inv excess from Belle II and DM relic density can be simultaneously explained in a simple extension of the SM. The model introduces a real scalar singlet ϕ acting as a DM candidate, and two heavy vector-like quarks Q, D with the same quantum numbers as the SM left-handed quark doublet and right-handed down-type quark singlet, respectively. All these new particles are odd under a ℤ2 symmetry while the SM particles are even. The model can successfully explain the Belle II anomaly and DM relic density for TeV-scale heavy quarks with hierarchical Yukawa couplings involving b and s quarks. At the same time, it can easily satisfy other flavour physics constraints. Direct detection searches utilizing the Migdal effect constrain some of the parameter space.
Hybrid analysis of radiative corrections to neutron decay with current algebra and effective field theory
Authors: Seng Chien-Yeah 
Published: July 2024

Abstract
We introduce a useful framework for high-precision studies of the neutron beta decay by merging the current algebra description and the fixed-order effective field theory calculation of the electroweak radiative corrections to the neutron axial form factor. We discuss the advantages of this hybrid method and show that it only requires a minimal amount of lattice QCD inputs to achieve a 10−4 theory accuracy for the Standard Model prediction of the neutron lifetime and the axial-to-vector coupling ratio λ, both important to the search for physics beyond the Standard Model.

Assessing fecal load with ultrasound in children with colorectal pathology: ReKiSo study
Authors: Erkel Daniel , Märzheuser Stefanie , Lindert Judith 
Published: July 2024

Abstract
Purpose
To evaluate bowel management for children with colorectal pathology by measuring transverse rectal diameter (TRD) and assessing fecal load with transabdominal rectal ultrasound (TRU).

Methods
Prospective case–control study of children receiving bowel management (BM) between 04/2023 and 04/2024 was done. There was inclusion of patients with Hirschsprung disease (HD), anorectal malformation (ARM) and functional constipation (FC). Patients with other congenital or neurological conditions were excluded. Control group consisted of inpatients and outpatients without abdominal complaints. FC was diagnosed according to ROM-IV-criteria. For HD and ARM, we followed a list of symptoms. To assess fecal load, we visualized the TRD using the Klijn (Klijn et al. in J Urol 172:1986–1988, 2004) method. The bladder was moderately full. The fecal load was assessed retrograde from the rectum. Follow-up was at 1/3/6 months. Secondary data were collected from medical records. Sample size calculated a priori and follow-up group with new gathered data.

Results
p value for TRD in all groups significant with p < 0.05 and in grouped follow-up.

Conclusion
Ultrasound is a useful tool for assessing fecal load and helps diagnose constipation and monitor BM. Irrespective of colorectal pathology, a cut-off of 3 cm seems to discriminate between children without constipation/overload symptoms and asymptomatic patients. We present a radiation-free method for monitoring bowel management.
Identification of ASMTL-AS1 and LINC02604 lncRNAs as novel biomarkers for diagnosis of colorectal cancer
Authors: Shakeri Fariba , Mohamadynejad Parisa , Moghanibashi Mehdi 
Published: July 2024

Abstract
Purpose
Colorectal cancer is one of the major leading causes of death worldwide, and available treatments for advanced colorectal cancer are not successful. Therefore, early detection of colorectal cancer is essential to improve patient survival, and biomarkers are potential tools to achieve this goal. Considering the key role of lncRNAs in cancers, the aim of this study is to identify lncRNAs involved in colorectal cancer as new potential prognosis biomarkers for CRC.

Methods
In this observational study, gene expression data obtained from the TCGA database were analyzed, Identification of differentially expressed mRNAs, miRNAs, and lncRNAs was performed, and ceRNA network was drawn. Also, survival analysis of patients was performed in order to identify potential biomarkers related to the diagnosis and prognosis of colon cancer. After confirming the results using the GSE39582 dataset, the expression of target lncRNAs in colorectal tumor tissues was also investigated to confirm the bioinformatic data.

Results
Analysis of the TCGA data showed that the expression of three lncRNAs—SNHG7, ASMTL-AS1, and LINC02604—that had the highest interaction with other miRNAs and mRNAs identified based on the ceRNA network was increased in colorectal cancer. Also, based on the ceRNA network, three microRNAs, hsa-let-7d-5p, hsa-mir-92a-3p, and hsa-mir-423-5p, and eight mRNAs, including CPA4, MSI2, RRM2, IGF2BP1, ONECUT2, HMGA1, SOX4, and SRM, were associated with all three mentioned lncRNAs, the expression of microRNAs was decreased and the expression of mRNAs was increased. By enrichment analysis, it was found that the target lncRNAs are involved in the processes of cell proliferation, apoptosis, and metastasis, indicating their importance in the development and malignancy of colorectal cancer. Furthermore, Kaplan–Meier analysis showed a significant increase in mortality in patients with higher expression levels of these lncRNAs. Analysis of the GSE39582 dataset, and real-time RT-PCR analysis, confirmed our bioinformatic results. Also, ROC analysis showed that SNHG7 was a relatively good promising biomarker (AUC = 0.73, p value = 0.02), while ASMTL-AS1 (AUC = 0.92, p value < 0.0001) and LINC02604 (AUC = 1.00, p value < 0.0001) emerged as excellent diagnostic biomarkers in colorectal cancer.

Conclusion
It seems that increased expression of lncRNAs ASMTL-AS1 and LINC02604 can serve as molecular biomarkers for CRC, possibly through the sponge hsa-let-7d-5p, hsa-mir-92a-3p, and hsa-mir-423 5p, which increases target mRNAs, which are effective in the carcinogenesis process.
