Transfer Learning Based Recurrent Neural Network Algorithm for Linguistic Analysis
Authors: Jiang Peipei , Chen Liailun , Wang Min-Feng
Published: September 2021

Each language is a system of understanding and skills that allows language users to interact, express thoughts, hypotheses, feelings, wishes, and all that needs to be expressed. Linguistics is the research of these structures in all respects: the composition, usage, and sociology of language, in particular, are the core of linguistics. Machine Learning is the research area that allows machines to learn without being specifically scheduled. In linguistics, the design of writing is understood to be a foundation for many distinct company apps and probably the most useful if incorporated with machine learning methods. Research shows that besides text tagging and algorithm training, there are major problems in the field of Big Data. This article provides a collaborative effort (transfer learning integrated into Recurrent Neural Network) to analyze the distinct kinds of writing between the language's linear and non-computational sides, and to enhance granularity. The outcome demonstrates stronger incorporation of granularity into the language from both sides. Comparative results of machine learning algorithms are used to determine the best way to analyze and interpret the structure of the language.
A Graph Theoretic Approach for Multi-Objective Budget Constrained Capsule Wardrobe Recommendation
Authors: Patil Shubham , Banerjee Debopriyo , Sural Shamik
Published: September 2021

Traditionally, capsule wardrobes are manually designed by expert fashionistas through their creativity and technical prowess. The goal is to curate minimal fashion items that can be assembled into several compatible and versatile outfits. It is usually a cost and time intensive process, and hence lacks scalability. Although there are a few approaches that attempt to automate the process, they tend to ignore the price of items or shopping budget. In this article, we formulate this task as a multi-objective budget constrained capsule wardrobe recommendation (
MOBCCWR
) problem. It is modeled as a bipartite graph having two disjoint vertex sets corresponding to top-wear and bottom-wear items, respectively. An edge represents compatibility between the corresponding item pairs. The objective is to find a 1-neighbor subset of fashion items as a capsule wardrobe that jointly maximize compatibility and versatility scores by considering corresponding user-specified preference weight coefficients and an overall shopping budget as a means of achieving personalization. We study the complexity class of
MOBCCWR
, show that it is NP-Complete, and propose a greedy algorithm for finding a near-optimal solution in real time. We also analyze the time complexity and approximation bound for our algorithm. Experimental results show the effectiveness of the proposed approach on both real and synthetic datasets.

Published: September 2021

Like many of the disasters that have preceded it, the COVID-19 pandemic is likely to have a profound impact on people’s mental health. Understanding its impact can inform strategies for mitigating negative consequences. This work seeks to better understand the impacts of COVID-19 on mental health by examining how discussions on mental health subreddits have changed in the three months following the WHO’s declaration of a global pandemic. First, the rate at which the pandemic is discussed in each community is quantified. Then, volume of activity is measured to determine whether the number of people with mental health concerns has risen, and user interactions are analyzed to determine how they have changed during the pandemic. Finally, the content of the discussions is analyzed. Each of these metrics is considered with respect to a set of control subreddits to better understand if the changes present are specific to mental health subreddits or are representative of Reddit as a whole. There are numerous changes in the three mental health subreddits that we consider, r/Anxiety, r/depression, r/SuicideWatch; there is reduced posting activity in most cases, and there are significant changes in discussion of some topics such as work and anxiety. The results suggest that there is not an overwhelming increase in online mental health support-seeking on Reddit during the pandemic, but that discussion content related to mental health has changed.
Knowledge-Guided Disentangled Representation Learning for Recommender Systems
Authors: Mu Shanlei , Li Yaliang , Zhao Wayne Xin , Li Siqing , Wen Ji-Rong
Published: September 2021

In recommender systems, it is essential to understand the underlying factors that affect user-item interaction. Recently, several studies have utilized disentangled representation learning to discover such hidden factors from user-item interaction data, which shows promising results. However, without any external guidance signal, the learned disentangled representations lack clear meanings, and are easy to suffer from the data sparsity issue.

In light of these challenges, we study how to leverage knowledge graph (KG) to guide the disentangled representation learning in recommender systems. The purpose for incorporating KG is twofold, making the disentangled representations interpretable and resolving data sparsity issue. However, it is not straightforward to incorporate KG for improving disentangled representations, because KG has very different data characteristics compared with user-item interactions. We propose a novel
K
nowledge-guided
D
isentangled
R
epresentations approach (
KDR
) to utilizing KG to guide the disentangled representation learning in recommender systems. The basic idea, is to first learn more interpretable disentangled dimensions (explicit disentangled representations) based on structural KG, and then align implicit disentangled representations learned from user-item interaction with the explicit disentangled representations. We design a novel alignment strategy based on mutual information maximization. It enables the KG information to guide the implicit disentangled representation learning, and such learned disentangled representations will correspond to semantic information derived from KG. Finally, the fused disentangled representations are optimized to improve the recommendation performance. Extensive experiments on three real-world datasets demonstrate the effectiveness of the proposed model in terms of both performance and interpretability.

Skeletal muscle is an endocrine organ secreting exercise-induced factors (exerkines), which play a pivotal role in interorgan cross talk. Using mass spectrometry (MS)-based proteomics, we characterized the secretome and identified thymosin β4 (TMSB4X) as the most upregulated secreted protein in the media of contracting C2C12 myotubes. TMSB4X was also acutely increased in the plasma of exercising humans irrespective of the insulin resistance condition or exercise mode. Treatment of mice with TMSB4X did not ameliorate the metabolic disruptions associated with diet induced-obesity, nor did it enhance muscle regeneration in vivo. However, TMSB4X increased osteoblast proliferation and neurite outgrowth, consistent with its WADA classification as a prohibited growth factor. Therefore, we report TMSB4X as a human exerkine with a potential role in cellular cross talk.

Published: September 2021

Bronchoalveolar lavage (BAL) samples from Severe Asthma Research Program (SARP) patients display suppression of a module of genes involved in cAMP-signaling pathways (BALcAMP) correlating with severity, therapy, and macrophage constituency. We sought to establish if gene expression changes were specific to macrophages and compared gene expression trends from multiple sources. Datasets included single-cell RNA sequencing (scRNA-seq) from lung specimens including a fatal exacerbation of severe Asthma COPD Overlap Syndrome (ACOS) after intense therapy and controls without lung disease, bulk RNA sequencing from cultured macrophage (THP-1) cells after acute or prolonged β-agonist exposure, SARP datasets, and data from the Immune Modulators of Severe Asthma (IMSA) cohort. THP monocytes suppressed BALcAMP network gene expression after prolonged relative to acute β-agonist exposure, corroborating SARP observations. scRNA-seq from healthy and diseased lung tissue revealed 13 cell populations enriched for macrophages. In severe ACOS, BALcAMP gene network expression scores were decreased in many cell populations, most significantly for macrophage populations ( P < 3.9e-111). Natural killer (NK) cells and type II alveolar epithelial cells displayed less robust network suppression ( P < 9.2e-8). Alveolar macrophages displayed the most numerous individual genes affected and the highest amplitude of modulation. Key BALcAMP genes demonstrate significantly decreased expression in severe asthmatics in the IMSA cohort. We conclude that suppression of the BALcAMP gene module identified from SARP BAL samples is validated in the IMSA patient cohort with physiological parallels observed in a monocytic cell line and in a severe ACOS patient sample with effects preferentially localizing to macrophages.
Population registration of echo flow in the big brown bat’s auditory midbrain
Authors: Warnecke Michaela , Simmons James A. , Simmons Andrea Megela
Published: September 2021

Echolocating bats navigate through cluttered environments that return cascades of echoes in response to the bat’s broadcasts. We show that local field potentials from the big brown bat’s auditory midbrain have consistent responses to a simulated echo cascade varying across echo delays and stimulus amplitudes, despite different underlying individual neuronal selectivities. These results suggest that population activity in the midbrain can build a cohesive percept of an auditory scene by aggregating activity over neuronal subpopulations.

Published: September 2021

We present a novel device, a manipulandum, that enables to image the contact between the finger and the contact surface during active manipulation of the device. The device is tested in a simple vertical oscillation task involving 18 participants. We demonstrate that substantial surface skin strains take place at the finger-object interface and argue that those deformations provide essential information for grasp stability during object manipulation.
The interaction between motion and texture in the sense of touch

Published: September 2021

Besides providing information on elementary properties of objects, like texture, roughness, and softness, the sense of touch is also important in building a representation of object movement and the movement of our hands. Neural and behavioral studies shed light on the mechanisms and limits of our sense of touch in the perception of texture and motion, and of its role in the control of movement of our hands. The interplay between the geometrical and mechanical properties of the touched objects, such as shape and texture, the movement of the hand exploring the object, and the motion felt by touch, will be discussed in this article. Interestingly, the interaction between motion and textures can generate perceptual illusions in touch. For example, the orientation and the spacing of the texture elements on a static surface induces the illusion of surface motion when we move our hand on it or can elicit the perception of a curved trajectory during sliding, straight hand movements. In this work we present a multiperspective view that encompasses both the perceptual and the motor aspects, as well as the response of peripheral and central nerve structures, to analyze and better understand the complex mechanisms underpinning the tactile representation of texture and motion. Such a better understanding of the spatiotemporal features of the tactile stimulus can reveal novel transdisciplinary applications in neuroscience and haptics.
Operational Evaluation of a Throughabout to Give Priority to Public Transport at Standard Roundabouts
Authors: Zakeri Sajjad , Choupani Abdoul-Ahad
Published: September 2021

The presence of roundabouts in the central business districts (CBD) of cities can reduce the travel speed of bus rapid transit (BRT) along the radial routes. A throughabout is an unconventional and low-cost design in which the central island is split to provide exclusive lanes for major traffic streams. Although the operation of throughabout has been limitedly investigated for private transport, it has been less considered by designers for public transport and for increasing the speed of the BRT system. The current study aims to evaluate the effects of throughabouts on private and public transports and to compare the design with standard roundabouts and conventional intersections. The calibrated and validated results of the microsimulation tool (AIMSUN) indicated that the throughabout improved the travel time of both public and private transports through better use of the space and kept the traffic flowing at all volume levels. The travel speed of the BRT in the throughabout was remarkably stable in both signal-controlled and unsignalized intersections. The standard roundabout was the second-best design. The throughabout can be very helpful in corridors along which the demand for the bus transit is high and the system needs to receive priority.

Published: September 2021

Purpose. This study evaluated the postoperative analgesic effect of ultrasound-guided single-point thoracic paravertebral nerve block (TPVB) combined with dexmedetomidine (DEX) in patients undergoing video-assisted thoracoscopic lobectomy. Methods. Sixty adult patients of the American Society of Anesthesiologists (ASA) I–III were randomly assigned into three groups (n = 20 each). G group: patients received routine general anesthesia; PR group: patients received 0.5% ropivacaine; and PRD group: patients received 0.5% ropivacaine with 1 μg/kg DEX. TPVB was performed in the T5 space before surgery, and then, general anesthesia induction and video-assisted thoracoscopic lobectomy were performed. Analgesics were administered through the patient-controlled analgesia (PCA) device intravenously. The background infusion of each PCA device was set to administer 0.02 μg/kg/h sufentanil, with a lockout time of 15 min, and a total allowable volume is 100 ml. Results. Compared to PR and G groups, the total sufentanil consumption after operation, the times of analgesic pump pressing, the pain score, and the incidence of postoperative nausea or vomiting in the PRD group were significantly reduced (

p
<
0.05

). Also, the duration of first time of usage of the patient-controlled analgesia (PCA) was longer. The heart rate (HR) and mean arterial pressure (MAP) during operation were lower in the PRD group as compared with the other two groups in most of the time. However, hypotension and arrhythmia occurred in three groups with no statistically significant difference. Conclusions. A small volume of TPVB with ropivacaine and DEX by single injection produced longer analgesia in patients undergoing video-assisted thoracoscopic lobectomy, reduced postoperative opioids consumption, and the incidence of side effects.

Published: September 2021

Digital twin (DT), machine learning, and industrial Internet of things (IIoT) provide great potential for the transformation of the container terminal from automation to intelligence. The production control in the loading and unloading process of automated container terminals (ACTs) involves complex situations, which puts forward high requirements for efficiency and safety. To realize the real-time optimization and security of the ACT, a framework integrating DT with the AdaBoost algorithm is proposed in this study. The framework is mainly composed of physical space, a data service platform, and virtual space, in which the twin space and service system constitute virtual space. In the proposed framework, a multidimensional and multiscale DT model in twin space is first built through a 3D MAX and U3D technology. Second, we introduce a random forest and XGBoost to compare with AdaBoost to select the best algorithm to train and optimize the DT mechanism model. Third, the experimental results show that the AdaBoost algorithm is better than others by comparing the performance indexes of model accuracy, root mean square error, interpretable variance, and fitting error. In addition, we implement empirical experiments by different scales to further evaluate the proposed framework. The experimental results show that the mode of the DT-based terminal operation has higher loading and unloading efficiency than that of the conventional terminal operation, increasing by 23.34% and 31.46% in small-scale and large-scale problems, respectively. Moreover, the visualization service provided by the DT system can monitor the status of automation equipment in real time to ensure the safety of operation.

The aim of this research work was to develop the optimal mechanical properties, namely, tensile strength, flexural strength, and impact strength of sisal and glass fiber‐reinforced polymer hybrid composites. The sisal, in the form of short fiber, is randomly used as reinforcements for composite materials, which is rich in cellulose, economical, and easily available as well as glass fibers have low cost and have good mechanical properties. In addition, epoxy resin and hardener were for the fabrication of composites by compression molding. The selected materials are fabricated by compression molding in various concentrations on volume basics. The combination of material compositions is obtained from the design of experiments and optimum parameters determined by the Response Surface Methodology (RSM). From the investigation of mechanical properties, the sisal is the most significant factor and verified by ANOVA techniques. The multiobjective optimal levels of factors are obtained by LINGO analysis.

Published: September 2021

Introduction. Stage IIB cervical cancer (CC) is an advanced stage CC with poor prognosis. Inflammatory response plays a crucial role in the development of CC, and systemic inflammatory indexes were related to the prognosis in several cancers. The objective of the study was to determine the prognostic value of platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), basophil-to-lymphocyte ratio (BLR), and systemic inflammation response index (SIRI) as inflammatory indexes in patients with stage IIB CC. Materials and Methods. A retrospective study was performed in 260 patients with stage IIB CC. PLR, NLR, MLR, BLR, and SIRI were obtained from routine blood tests. Prognosis information of the patients was acquired from regular clinical follow-up. Recurrence and response to therapy were determined through electronic medical records (EMRs). Correlations of the inflammatory indexes with overall survival (OS), progression-free survival (PFS), recurrence, and response to therapy were analyzed using SPSS version 26.0 software. Results. Receiver operating characteristic (ROC) curve analyses suggested that NLR, MLR, and SIRI had better predictive value than PLR as well as BLR in the prognosis and recurrence risk. Both univariate and multivariate survival analyses showed that higher NLR and MLR were significantly associated with shorter OS as well as PFS, whereas SIRI was not an independent predictive factor of PFS. Chi-square test results revealed that increased NLR was significantly correlated with higher recurrence rate (

P
=
0.046

), and increased MLR showed significant correlation with elevated recurrence risk (

P
=
0.002

). Univariate and binary logistic regression analyses for response to therapy indicated that elevated NLR was associated with decreased complete remission (CR) rate (

P
=
0.031

), and the

P

value lost statistical significance while being adjusted by tumor size (

P
=
0.108

). Conclusions. For patients with stage IIB CC, both NLR and MLR are independent prognostic factors as well as risk factors for recurrence; NLR serves as a potential marker for therapeutic response.
Effect of Ce Addition on Adsorption and Oxidation of NO over MnOx/Al2O3
Authors: Mou Chunhui , Li Hui , Dong Ning , Hui Shien , Wang Denghui
Published: September 2021

The MnO[Formula: see text]/Al2O3 catalysts with different Ce content doping were prepared by an ultrasonic impregnation method, and the catalytic activity for NO oxidation removal was tested in a fixed-bed quartz tube furnace. Simultaneously, the catalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), full-automatic physical-chemical adsorption instrument, and field emission scanning electron microscope (FESEM) to analyze the effect of Ce addition on the adsorption capacity and catalytic activity. Experimental results validated that the activity of the MnO[Formula: see text]/Al2O3 catalyst was greatly promoted with Ce addition. According to the characterization results, it could be concluded that Ce doping led to significant changes in the crystalline phase on the catalyst surface, which increased the relative content of surface lattice oxygen and promoted the catalytic oxidation of NO. By observing the physical properties of the surface and analyzing the surface elements of the catalyst, it could be inferred that a manganese-cerium solid solution was formed on the surface of Mn0.4Ce0.05/Al. Moreover, Ce addition increased the catalyst pore size, which enhanced the adsorption and contact of NO and O2 with the active sites on the catalyst surface, and reduced the resistance of the reactants during internal diffusion. All these variations assigned to Mn0.4Ce0.05/Al were favorable for the catalytic oxidation of NO.
Value of Serum Glycocholic Acid and Total Bile Acids in Predicting Maternal and Perinatal Outcomes in Intrahepatic Cholestasis of Pregnancy
Authors: Fu Chong , Xu Yali
Published: September 2021

Objective. To see whether serum glycocholic acid (CG) and total bile acids (TBA) can predict maternal and perinatal outcomes in pregnant women with intrahepatic cholestasis (ICP). Method. The observation group consisted of 80 women with ICP who were treated in our hospital, whereas the control group consisted of 50 ordinary women who were also treated at our hospital at the same time. The levels of CG and TBA in the two groups were determined independently, and the differences in poor perinatal outcomes were compared. Finally, the predictive diagnostic value of CG and TBA for poor perinatal outcomes in ICP mothers was displayed using the Spearman correlation between CG and TBA and Apgar. The maternal CG and TBA levels in the observation group were substantially higher than in the control group (P0.05). The observation group had more significant maternal-fetal discomfort, neonatal asphyxia, preterm birth, and perinatal death than the control group (P0.05). The risk of poor perinatal outcomes in ICP mothers rose when TBA and CG levels increased (P0.05). Apgar ratings were inversely associated with CG and TBA (r = −0.8251 and r = −0.5969, respectively, P0.05). The CG and TBA diagnostic AUCs for unfavorable perinatal outcomes in ICP mothers were (P0.05). Conclusion. CG and TBA have a high diagnostic value for ICP and may better predict and identify poor prenatal outcomes. It is suitable for clinical use.

Published: September 2021

Numerical simulations are carried out to study the flow around two tandem square cylinders (SC) under the effect of spacing ratio(g/D) and splitter plate length (l/D) for a fixed Reynolds number (Re) = 100. The g/D is varied from 0 to 10 and l/D is varied from 0.5 to 10. The splitter plate length is found to have strong effect on vortex shedding and fluid forces. The maximum reduction in mean drag coefficient is observed at l/D = 8, that is 15% and 78% for upstream and downstream cylinders, respectively. The maximum reduction in root-mean-square value of lift coefficient is found at l/D = 10, that is 99%. The flow pattern at both of these points is steady flow. There is 100% vortex shedding suppression for l/D > 5. The observed flow patterns for flow past tandem cylinders without splitter plate are; single bluff body (SBB), steady flow (SF), quasi-steady flow (QSF), fully developed flow (FDF) and fully developed two-row vortex street flow (FDTRVS) regimes. SBB, QSF and SF regimes were observed in presence of splitter plate.

Published: September 2021

In view of the differences and uniqueness of intelligence between people, the application of new educational thoughts is the need of the time; in the educational atmosphere created by the intelligent environment, it is urgent to seek a path of integration and symbiosis. This article takes the development of children's sports driven by the intelligent education project as the main research object, selects our city's children's football as the representative of sports events to carry out case studies, and uses the spectrum education program to explore the intelligent development of intelligent children with logical and mathematical advantages in the field of sports. This paper designs a data fusion method for homogeneous smart sensors. The correlation degree of the nodes in the continuous sampling period is obtained by defining the spatial correlation coefficient, and the confidence value and coherent degree of integration are obtained by applying the angle of attraction between nodes in the definition of fusion strategy in the evaluation of neighborhood, and lastly, the node coefficient of weight is reallocated to validate the fused expression. The feasibility of the simulation is used to confirm the trustworthiness of the solution. Based on the development status of children’s physical education, this article uses intelligent mobile networks to find out the problems in the physical education classes of kindergarten teachers and the problems that are not compatible with the development of children’s physical education. The kindergarten normal students receive targeted physical education and acquire solid professional skills. The study indicates that the percentage of basic motor and basic motility classes in the city's kindergartens is 100%, suggesting that all preschools in the city operate fundamental motor practice classes for a group of children. They have fully realized that basic movement exercises have an impact on children’s body shape.

Published: September 2021

Background. Hepatoblastoma (HB) is the most common liver malignancy in pediatrics, but the treatment for this disease is minimal. This study is aimed at exploring the effect of FoxO1 and SREBP-1c on HB and their mechanism. Methods. FoxO1, SREBP-1c, FASN, ACLY, ACC, and MAGL expressions in tissue samples were detected by RT-qPCR and WB. IHC was utilized to measure FASN content. Overexpression and knockdown of FoxO1 and sSREBP-1c were performed on Huh-6 cells. Cell proliferation, migration, and invasion were examined by CCK8, scratch, and transwell assay. ELISA was performed to test the ATP, FAO, NEFA, and Acetyl-CoA contents. ChIP was used to detect the interaction between SREBP-1c protein and the FoxO1 gene. In vivo tumorigenesis was conducted on mice. The morphology of tumor tissue sections was observed by HE staining. Results. FoxO1 expression was downregulated in HB tissue, while the expressions of SREBP-1c, FASN, ACLY, ACC, and MAGL were upregulated. In Huh-6 cells and mouse tumor tissues, FoxO1 knockdown resulted in increased cell proliferation, migration, and invasion and active fatty acid metabolism. On the contrary, after the knockdown of SREBP-1c, cell proliferation, migration, and invasion were weakened, and fatty acid metabolism was significantly reduced. SREBP-1c interacted with the promoter of the FoxO1 gene. When FoxO1 was knocked down, the tumor tissue was more closely packed. After the knockdown of the SREBP-1c gene, the structure of tumor cells was deformed. Conclusion. FoxO1 and SREBP-1c inhibited each other in HB, leading to the increase of intracellular fatty acid metabolism, and ultimately facilitated the development of HB.

Deviation correction of building is a big challenge for engineers. Without powerful technique for deviation, no special guidance can be followed to conduct the deviation rectification of buildings, which brings numerous failure cases. In this study, a case study was performed to provide insight into the behavior of a special technique for deviation rectification of building near excavation. The new technique was introduced firstly, and then, the field test data, in terms of lateral displacement of wall of pit, water level deviation, and soil deformation around pile of the building, were addressed to show the performance of the function of each process and the mechanism of it. The results show that this new technique for the deviation rectification of building works very well to uplift the whole building to reach the destination position (maximum uplift = 9.71 cm) and meets the requirement of design demand, without negative effect on the adjacent excavation reported.
Blockchain-Enabled Intelligent Video Caching and Transcoding in Clustered MEC Networks
Authors: Li Yan , Wan Zheng
Published: September 2021

In recent years, the number of smart devices has exploded, leading to an unprecedented increase in demand for video live and video-on-demand (VoD) services. Also, the privacy of video providers and requesters and the security of requested video data are much more threatened. In order to solve these issues, in this paper, a blockchain-enabled CMEC video transmission model (Bl-CMEC) for intelligent video caching and transcoding will be proposed to ensure the transactions’ transparency, system security, user information privacy, and integrity of the video data, enhance the ability of severs in actively caching popular video content in the CMEC system, and realize transcoding function at network edge nodes. Furthermore, we chose a scheme based on deep reinforcement learning (DRL) to intelligently access the intracluster joint caching and transcoding decisions. Then, the joint video caching and transcoding decision smart contract is specially designed to automatically manage the transaction process of the joint caching and transcoding service, which records key information of joint caching and transcoding transactions and payment information on a continuous blockchain. The simulation results demonstrate that the proposed Bl-CMEC framework not only can provide users with better QoE performance for video streaming service but also can ensure the security, integrity, and consistency for the video providers, video requesters, and video data.
Influence of Lightweight Foamed Concrete as Backfill Material on Stress and Deformation of Buttressed Earth-Retaining Wall
Authors: Qiu Youqiang , Liu Yang , Zhang Liujun , Wang Zhanqi
Published: September 2021

Controlling settlement and earth pressure behind retaining wall in soft soil area are ongoing practical problems for the construction and operation of highway, which are mainly caused by the poor nature of soft soil. To reduce the pushing force on retaining wall and subgrade settlement, the authors propose the use of lightweight foamed concrete as subgrade filler behind the buttressed earth-retaining wall. However, the mechanical properties and deformation behavior of the buttressed earth-retaining wall remain unknown when lightweight foamed concrete is used as a backfill behind the wall. To solve this problem, a scale model of the subgrade filled with lightweight foamed concrete behind the buttressed earth-retaining wall is established to determine its stress and deformation characteristics under different factors. Lateral earth pressures and wall displacements at different elevations of the retaining wall model were monitored during the tests. Then, a series of orthogonal experiments are conducted to analyse and compare the effects of overload, density, and replacement thickness of lightweight foamed concrete on the earth pressure and displacement of this retaining wall. The results show that the size of earth pressures at the same position of retaining wall is affected by overload, density, and replacement thickness of lightweight foamed concrete, but its change of distribution form is only related to the replacement thickness of this backfill. Additionally, the primary-secondary relations of different factors’ influence extent on the forces and deformation of the buttressed earth-retaining wall filled with lightweight foamed concrete as backfill are obtained by using range analysis method.

Published: September 2021

ASrank has been proposed as an improved version of the ant colony optimisation (ACO) model. However, ASrank includes behaviours that do not exist in the actual biological system and fall into a local solution. To address this issue, we developed ASmulti, a new type of ASrank, in which each agent contributes to pheromone depositions by estimating its rank by interacting with the encountered agents. In this paper, we attempt further improvements in the performance of ASmulti by allowing agents to consider their position in a local hierarchy. Agents in the proposed model (AShierarchy) contribute to pheromone depositions by estimating the consistency between a local hierarchy and global (system) hierarchy. We show that, by using several TSP datasets, the proposed model can find a better solution than ASmulti.

This study explores the multiple organizational relationships between frontline miners, managers, and supervisors to reveal the human organizational risks of coal mine safety and health management. Data were collected from six high‐risk rock burst underground mining companies operating in western, central, north‐eastern, and south‐eastern regions of China. A total of 1105 respondents from the three core groups were investigated. Descriptive statistics and paired test methods were used to empirically analyze the deteriorated and dislocated relationships between multiple roles. The specific conclusions are as follows: (1) Miners’ perception of relationship quality is the lowest, and the managers’ perception of relationship quality is the highest. (2) “Closeness” relationship is expressed among peer colleagues for all multiple roles. (3) The deteriorated relation rate of miners averagely reached 19.67%, and that of supervisors averagely reached 17.63%, thereby mostly reaching 27.8% for miners with regard to supervisors. (4) The workers in high positions easily have a phenomenon of “overestimated confidence” in the perception of dislocated relationships, and the “miners‐supervisors” and “supervisors‐manager” dual‐core contradiction have obviously been emerging. (5) The valuable, harmonious, and extent degree are relatively lowest in all relationship items.

Computer technology plays a prominent role in almost every aspect of daily life including education, health care, online shopping, advertising, and even in homes. Computers help to make daily tasks much easier and convenient. Among social media, YouTube is a well‐known social sharing networking service. As more and more people join social media and become everyday users, brands have also increased their online engagement. However, it is still unclear how to effectively measure value and return on advertising using social media. As of 2021, more than 31 million YouTube channels around the globe have been opened. In this paper, we consider YouTube advertising to check its effectiveness and benefits gained. Certain statistical tools are adopted to measure the extent of advertising benefits and their correlation in creating effective advertising campaigns on YouTube. Simple linear regression analysis is performed on the data representing the YouTube advertising budget of a company and the sales data of that company. Furthermore, we develop a new statistical distribution to provide the best description of the YouTube advertising data. The result of this research shows that YouTube is an effective medium for advertising and has a strong relationship with sales.

In real life, people’s life gradually tends to be simple, so the convenience of online shopping makes more and more research begin to explore the convenience optimization of shopping, in which the fitting system is the research product. However, due to the immaturity of the virtual fitting system, there are a lot of problems, such as the expression of clothing color is not clear or deviation. In view of this, this paper proposes a 3D clothing color display model based on deep learning to support human modeling‐driven. Firstly, the macro‐micro adversarial network (MMAN) based on deep learning is used to analyze the original image, and then, the results are preprocessed. Finally, the 3D model with the original image color is constructed by using UV mapping. The experimental results show that the accuracy of the MMAN algorithm reaches 0.972, the established three‐dimensional model is emotional enough, the expression of the clothing color is clear, and the difference between the color difference and the original image is within 0.01, and the subjective evaluation of volunteers is more than 90 points. The above results show that it is effective to use deep learning to build a 3D model with the original picture clothing color, which has great guiding significance for the research of character model modeling and simulation.

The development of information technology and the advancement of the process of educational informatization have provided technical support for education and education reform. The virtual simulation teaching mode is no longer a new thing for people, and it is more and more accepted by people familiar with it. Induction and analysis of short message texts generated by students’ online learning can fully understand students, make effective adjustments to the classroom, guide teachers’ teaching practice, and optimize the classroom, thereby improving students’ learning ability, practical ability, innovation ability, and collaboration. To study the effect of virtual simulation education on improving the skills of medical students, this paper is based on video training and education of virtual reality side-cut high-simulation simulator using case analysis and literature analysis methods. It collects data from databases and builds on online education. The model was developed, and a large number of relevant pieces of literature were read and analyzed through the literature survey method. The research results show that virtual simulation teaching can effectively improve students’ technical thinking and ability. Students’ technical thinking and ability are about 30% higher than traditional teaching methods, and the cooperation consciousness between students reaches 0.8 consciousness, which can solve the contradiction between popularization and improvement. And to solve the problems of polarization and transformation of underachievers, students’ personalities can be fully displayed and developed, and education and teaching will be on the track of quality education. This shows that training videos based on virtual reality technology can play a very good role in improving students’ technical mastery.

Published: September 2021

Progressive abnormality and loss of axons and neurons in the central nervous system (CNS) cause neurodegenerative diseases (NDs). Protein misfolding and its collection are the most important pathological features of NDs. Astrocytes are the most plentiful cells in the mammalian CNS (about 20–40% of the human brain) and have several central functions in the maintenance of the health and correct function of the CNS. Astrocytes have an essential role in the preservation of brain homeostasis, and it is not surprising that these multifunctional cells have been implicated in the onset and progression of several NDs. Thus, they become an exciting target for the study of NDs. Over almost 15 years, it was revealed that curcumin has several therapeutic effects in a wide variety of diseases’ treatment. Curcumin is a valuable ingredient present in turmeric spice and has several essential roles, including those which are anticarcinogenic, hepatoprotective, thrombosuppressive, cardioprotective, anti-arthritic, anti-inflammatory, antioxidant, chemopreventive, chemotherapeutic, and anti-infectious. Furthermore, curcumin can suppress inflammation; promote angiogenesis; and treat diabetes, pulmonary problems, and neurological dysfunction. Here, we review the effects of curcumin on astrocytes in NDs, with a focus on Alzheimer’s disease, Parkinson’s disease, multiple scleroses, Huntington’s disease, and amyotrophic lateral sclerosis.

Introduction: Although spinal anesthesia (SA) may reduce postoperative morbidity, most urologists perform flexible ureterorenoscopy (fURS) under general anesthesia (GA). The objective of our study is to provide technical details, results, complications, and patients’ satisfaction with fURS performed under exclusive SA. Methods: We analyzed all consecutive fURS performed under SA to treat renal stones from March 2011 to February 2017. Details of technique, operative time, outcomes, need for further treatments, complications, and patients’ satisfaction were evaluated. Results: Two hundred thirty-four fURS under SA were considered. SA was performed through L2-L3 vertebral interspace in 64.1%. Patients were discharged the same day of surgery. Mean stone burden was 13.5 ± 6.6 mm and mean operative time 76.9 ± 34.6 min. Single-procedure SFR was 69.7%. Further treatments were performed in 22.8%. 96.6% had no anesthesia-related complications. No Clavien-Dindo grade ≥ IIIb complications were noticed. 99.6% of patients were satisfied with SA. No cases of conversion from SA to GA occurred. Conclusion: fURS can be performed safely and efficiently under SA, taking into account a few details of the technique. Patients’ satisfaction with SA is very high, and complications are rare. Although SA is usually adopted in unfit patients for GA, it may be considered as a viable alternative in fit patients.
