(Invited) Kinetics and Thermodynamics of Swcnts and Bnnts Encapsulation with α-Sexithiophene in Liquid Phase
Authors: Allard Charlotte , Desjardins Patrick , Gaufres Etienne , Martel Richard
Published: July 2022

Single-Walled Carbon Nanotubes (SWNTs) and Boron Nitride Nanotubes (BNNTs) come with hollow 1D centers, which can serve to define narrow spaces for encapsulating small organic dyes. The encapsulation process is of scientific interest because it can be used to tailor the optical properties of the resulting dyes@NTs nanohybrids. Past works have shown that the dyes@SWCNT exhibits a strongly enhanced Raman scattering cross section, while the dyes@BNNTs do emit robust, generally red-shifted, luminescence at wavelengths down to the near-IR. In both cases, the nanotube protects the encapsulated dyes from photobleaching, provides high confinement, and reinforces intermolecular interactions between dyes into specific aggregation states.

Here, we compare the liquid phase encapsulation process of α-sexithiophene (6T), which is a conjugated rod-like dye, inside SWCNTs and BNNTs. Raman and luminescence imaging experiments are used to monitor the 6T encapsulation process of a large ensemble of individual nanotubes in liquid-phase. This method probes statistically the encapsulation kinetics using hundreds of individual nanotubes according to various parameters (dye concentration and temperature). The results highlight a kinetic model in which single and double aggregates is formed sequentially. This kinetics and the associated thermodynamic parameters for the 6T encapsulation will be presented and discussed so as to gain a better control over the emission properties of the nanohybrids.
(Invited) Quantum Emission Assisted By Energy Landscape Modification in Pentacene-Decorated Carbon Nanotubes
Authors: Li Zhen , Otsuka Keigo , Yamashita Daiki , Kozawa Daichi , Kato Yuichiro K.
Published: July 2022

Photoluminescent carbon nanotubes are expected to become versatile room-temperature single-photon sources that have applications in quantum information processing. Quantum emission from carbon nanotubes is often induced by localization of excitons or exciton-exciton annihilation. Here, we modify the local energy landscape of excitons by decorating nanoscale pentacene particles onto air-suspended single-walled carbon nanotubes [1]. Directional exciton diffusion from the undecorated region to the decorated site is demonstrated, suggesting exciton trapping induced by local dielectric screening from pentacene particles. Photoluminescence and photon correlation measurements on a representative carbon nanotube reveal enhanced exciton-exciton annihilation and single-photon emission at room temperature. Pentacene particles are shown to promote strong photon antibunching at the decorated site, indicating that noncovalent functionalization using molecules can be an effective approach for energy landscape modification and quantum emission in carbon nanotubes.

(Invited) High Temperature Light Emission Spectra of Metallic Carbon Nanotubes Under Different Heating Methods
Authors: Nishihara Taishi , Takakura Akira , Miyauchi Yuhei
Published: July 2022

Semiconducting single-walled carbon nanotubes (SWCNTs) show exceptional optical properties such as excitonic thermal radiation under thermal equilibrium [1,2] as well as exciton luminescence under nonequilibrium conditions, which potentially provides various promising applications including photonic and thermo-optic devices. With regard to the counterpart, metallic SWCNTs, high-temperature light emission induced by Joule heating has been reported [3,4], but the effects of nonequilibrium induced by the current injection on the light emission remain to be clarified. Here, we report comparison of high-temperature light emission from an identical individual metallic SWCNT under laser- and Joule-heating conditions. The spectral shapes were qualitatively different depending on the heating methods. We will discuss these high-temperature light emission phenomena quantitatively in terms of the electron and phonon distribution. [1] T. Nishihara, A. Takakura, Y. Miyauchi, and K. Itami, Nat.

(Invited) Nanoelectronics Based on Assembled High-Density and High-Semiconducting-Purity Carbon Nanotube Films
Authors: Zhou Chongwu
Published: July 2022

Carbon nanotubes hold great promise for high-performance electronics but also face significant challenges in terms of assembly and integration. On one hand, aligned carbon nanotubes are proposed as an alternative to III-V semiconductor technologies in radio frequency (RF) applications because of their high linearity as amplifiers and compatibility with CMOS electronics. We will first report high-performance RF transistors with operation frequencies beyond 100 GHz. These devices are built upon high-density (~50 nanotubes / micron) and high semiconducting purity (> 99.99%) aligned single-wall carbon nanotube films assembled at wafer scale. With gate length ~110 nm and T-shaped gate to reduce the gate charging resistance, the devices showed an extrinsic cutoff frequency and maximum oscillation frequency of over 100 GHz. The performance surpasses the 90 GHz cutoff frequency of radio-frequency CMOS transistors with gate length of 100 nm and is close to the performance of GaAs technology. [1] On the other hand, Carbon nanotubes are ideal candidates for beyond-silicon nanoelectronics because of their high mobility and low-cost processing; however, n-type transistors based on assembled aligned nanotubes has not been reported yet. Fabrication of n-type behavior field effect transistors (FETs) based on assembled aligned CNT arrays is needed for advanced CNT electronics. We will report a scalable process to make n-type transistors based on assembled aligned CNT arrays. Air-stable and high-performance n-type CNT FETs are achieved with high yield by combining atomic layer deposition dielectric and Ti contacts with gold overcoating, which are stable in air and widely used for III-V semiconductors. We also systematically studied the contribution of metal contacts and atomic layer deposition passivation in determining the transistor polarity. [2] Based on these experimental results, we report the successful demonstration of complementary metal-oxide-semiconductor inverters with good performance, which paves the way to realizing the promising future of carbon nanotube nanoelectronics.

(Invited) Novel Designs for Single Photon Detection
Authors: Leonard Francois
Published: July 2022

Photodetection plays a key role in basic science and technology, with exquisite performance having been achieved down to the single photon level. Further improvements in photodetectors would open new possibilities across a broad range of scientific disciplines, and enable new types of applications. However, it is still unclear what is possible in terms of ultimate performance, and what properties are needed for a photodetector to achieve such performance. In this presentation, I will discuss recent theoretical and experimental work to address this question. On the theoretical front, we present a new general framework to establish the fundamental properties of photodetectors from a fully quantum perspective, and show what basic features are needed to achieve high performance. Novel photodetector designs emerge from these considerations, and we present experiments with carbon nanotube devices to test these new designs.

Published: July 2022

Altered choline metabolism plays a role in both human and murine sepsis-associated acute kidney injury (SA-AKI), and choline administration in experimental SA-AKI improved renal function. These findings indicate that 1) mouse models can help interrogate clinically relevant mechanisms and 2) choline supplementation may ameliorate human SA-AKI. Future research will investigate clinically the impact of choline supplementation on human renal function in sepsis and, using model systems, how choline mediates its effects.

Published: July 2022

LN requires aggressive immunosuppression to improve long-term outcomes. Current indicators of remission take several months to normalize, prolonging treatment regiments in some cases. Serpin-A3 is present in urine of patients with proliferative LN. We evaluated the excretion of serpin-A3 in serial samples of patients with proliferative LN during the first year after flare. We found that uSerpA3 correlates with kidney inflammation and its decline at early points predicts the response to therapy 1 yr after flare.

First, a LPV model of WTS subject to disturbances and actuator fault is obtained. Using this model, unknown input observer (UIO) is developed to estimate the WTS fault and state variables. Then, an integral tracking controller for LPV systems is developed. Based on the Lyapunov and

Authors: Zhong Liyang
Published: July 2022

Whether minors can grow up healthily is the key to the happiness and peace of hundreds of millions of families, the great rejuvenation of the Chinese nation, and the development of the country. For better legal protection of minors’ sexual autonomy, China has put forward the application and analysis of minors’ sexual autonomy under legal protection under big data. This paper analyzes and compares the applied conventional technology and big data technology. Through the analysis of the impact of different technology applications on minors’ sexual autonomy and the legal protection of minors’ sexual autonomy, it can be seen that the protection and application of laws on minors’ sexual autonomy under big data technology can better safeguard the legitimate rights and interests of minors’ sexual autonomy. This is more conducive to protecting the healthy growth of minors and implementing the idea of socialist harmony and development. We should establish a good network environment and network order, effectively reduce the infringement of minors’ sexual rights, better protect minors’ sexual rights, build a good social environment, promote the stable development of society, and maintain the peace and happiness of families.

Authors: Yun Sang Jo , Park Jin-Woo
Published: July 2022

In the 1970s, Gian‐Carlo Rota constructed the umbral calculus for investigating the properties of special functions, and by Kim‐Kim, umbral calculus is generalized called λ‐umbral calculus. In this paper, we find some important relationships between degenerate Changhee polynomials and some important special polynomials by expressing the Changhee polynomial as a linear combination of some special polynomials. In addition, we derive some interesting identities related to degenerate poly‐Changhee polynomials and some important special functions by using λ‐umbral calculus.
[Retracted] Detection of WBC, RBC, and Platelets in Blood Samples Using Deep Learning
Authors: Alhazmi Lamia
Published: July 2022

A blood count is one of the most important diagnostic tools in medicine and one of the most common procedures. It can reveal important changes in the body and is commonly used as the first stage in the process of evaluating patients’ health. Even though this is a common practice, delivering examinations in laboratories can be difficult due to the availability of expensive technology that requires frequent maintenance. This study is developing an alternative deep learning computational model capable of automatically detecting cells in images of blood samples. Using object detection libraries, it was possible to train a model that was focused on this task and capable of detecting cells in images with adequate accuracy. When the identification of cells in images of blood samples was taken into account in the best results obtained, it was possible to count white cells with an accuracy of one hundred percent, red cells with an accuracy of 89%, and platelets with an accuracy of 96%, which generated subsidies to develop the primary components of a blood count. The components that were supposed to classify the various types of white cells were not carried out due to the limits of the dataset provided. On the other hand, the study can be broadened to include further works that deal with this issue because it produced satisfactory results.
Membership Inference Defense in Distributed Federated Learning Based on Gradient Differential Privacy and Trust Domain Division Mechanisms
Authors: Liu Zhenpeng , Li Ruilin , Miao Dewei , Ren Lele , Zhao Yonggang
Published: July 2022

Distributed federated learning models are vulnerable to membership inference attacks (MIA) because they remember information about their training data. Through a comprehensive privacy analysis of distributed federated learning models, we design an attack model based on generative adversarial networks (GAN) and member inference attacks (MIA). Malicious participants (attackers) utilize the attack model to successfully reconstruct training sets of other regular participants without any negative impact on the global model. To solve this problem, we apply the differential privacy method to the training process of the model, which effectively reduces the accuracy of member inference attacks by clipping the gradient and adding noise to it. In addition, we manage the participants hierarchically through the method of trust domain division to alleviate the performance degradation of the model caused by differential privacy processing. Experimental results show that in distributed federated learning, our designed scheme can effectively defend against member inference attacks in white-box scenarios and maintain the usability of the global model, realizing an effective trade-off between privacy and usability.

Published: July 2022

Coronary heart disease has an intense impact on human life. Medical history-based diagnosis of heart disease has been practiced but deemed unreliable. Machine learning algorithms are more reliable and efficient in classifying, e.g., with or without cardiac disease. Heart disease detection must be precise and accurate to prevent human loss. However, previous research studies have several shortcomings, for example,take enough time to compute while other techniques are quick but not accurate. This research study is conducted to address the existing problem and to construct an accurate machine learning model for predicting heart disease. Our model is evaluated based on five feature selection algorithms and performance assessment matrix such as accuracy, precision, recall, F1-score, MCC, and time complexity parameters. The proposed work has been tested on all of the dataset'sfeatures as well as a subset of them. The reduction of features has an impact on theperformance of classifiers in terms of the evaluation matrix and execution time. Experimental results of the support vector machine, K-nearest neighbor, and logistic regression are 97.5%,95 %, and 93% (accuracy) with reduced computation timesof 4.4, 7.3, and 8seconds respectively.

Authors: Li Qi , Li Xianglan , Guo Li
Published: July 2022

In order to study the influence of acid corrosion on the quality, elastic modulus, tensile strength, elongation, and other properties of epoxy mortar test block and CFRP bolt, the durability test and mechanical properties test of CFRP bolt under accelerated corrosion conditions were proposed. An epoxy mortar test block was soaked in acidic solution for 90 d, and the quality, elastic modulus, tensile strength, elongation, and other properties of CFRP bolt were analyzed. Through the analysis of test data, the load-slip relationship curve of bolt was obtained and the Arrhenius equation was used. The relationship curve between tensile strength retention and logarithm of time in test environment was obtained, and the concept of conversion factor TSF was introduced to predict the strength retention of anchor corroded by acid rain for 20 years in service. The experimental results show that the maximum loss rates of mass, elastic modulus, and compressive strength of epoxy mortar test block are 1.98%, 2.81%, and 11.25%, respectively, during 90 d immersion in acidic solution. The maximum loss rates of mass, elastic modulus, tensile strength, and elongation of CFRP bolt are 0.65%, 3.29%, 6.51%, and 5.06%, respectively. Based on the analysis of the test data, the load-slip curve of the bolt is obtained, which indicates that acid corrosion reduces the bond performance of CFRP bolt. The bond-slip curve of bolt after 90 d acid corrosion was obtained by further analysis of experimental data. Conclusion. The experiment has certain engineering application values.

Published: July 2022

Even though cytopenia caused by either chemotherapy or radiotherapy is a common complication in cancer patients, chemoradiotherapy remains an essential treatment for the majority of patients. The purpose of this study was to look into the clinical efficacy and cost‐effectiveness of recombinant human thrombopoietin (rhTPO) in treating chemo‐ or chemoradiotherapy‐induced grade II, III, and IV thrombocytopenia. From December 2019 to November 2020, 233 lung cancer patients admitted to our hospital with chemotherapy‐ or chemoradiotherapy‐induced thrombocytopenia were enrolled and treated with rhTPO. The study's findings revealed a significant disparity in the use of concurrent chemoradiotherapy in patients with grade II, III, and IV thrombocytopenia. All costs, including rhTPO treatment costs, platelet costs, drug costs, and nondrug costs, tended to rise as the severity of thrombocytopenia increased. In the treatment of chemotherapy or radiotherapy‐induced thrombocytopenia, rhTPO has shown good clinical efficacy. In the treatment of grade II thrombocytopenia, rhTPO has a favorable economic evaluation. As a result, early intervention and thrombocytopenia treatment should be provided, which warrants further clinical investigation.
Fully Mechanized Mining Technology and Practice of Water Conservation with Large Gravity Filling of Aeolian Sand‐Like Paste
Authors: Liu Pengliang
Published: July 2022

Aiming at the serious problem of Salawusu formation aquifer damage caused by caving mining in Yuyang coal mine, the technique of mechanized backfill mining with Aeolian sand‐like paste was invented. Aeolian sand was used as aggregate and alkali‐activated fly ash as cementing agent in the backfill material. Slurry ratio was studied where the water‐sand ratio was 1 : 1.3 and the mass concentration was 72%, while slurry initial fluidity could reach 210 m. The author proposed the local resistance loss calculation method of slurry pipeline transportation, and the field gravity transport test results showed that resistance loss of unit length elbow was 4.26 times as big as loss of resistance along path; thus the pipeline diameter with 14.9 gravity of self‐flowing was determined, and the pipeline flow design precision was improved by more than 10%. The backfill capacity could reach 360 m3/h and the running energy consumption was lower because of adopting backfill station model with double pulping system and underground equipment pool. The author also put forward whole backfill space sealing in which cloth consumption was only 40% of bag backfill. Industrial test showed that the backfill mining technique met requirements of water resources protection, primarily because the filling rate was 98.5% in goaf, strata behavior appeared slightly, roof water leaching was less than 2 m3/d, and surface subsidence value was only 38 mm. There were great breakthroughs in cost and production efficiency in this technology compared with similar technologies.
MicroRNA-424-5p Alleviates Isoflurane Anesthesia-Induced Neurotoxicity in Human Embryonic Stem Cell-Derived Neurons by Targeting FASN
Authors: Gu Xiaojiao , Yue Wei , Xiu Mingyu , Zhang Quanyun , Xie Rufeng
Published: July 2022

Isoflurane (ISO) is a type of anesthetic that might cause neurotoxicity in children. Although miR-424-5p is considerably downregulated in ISO-treated rat brain samples, its physiological role in ISO-induced neuronal injury in human embryonic stem cell-derived neurons remains unknown (hESC-derived neurons). miR-424-5p expression and fatty acid synthase (FASN) in ISO-treated hESC-derived neurons were tested via qRT-PCR. The amount of protein for Bax, Cleaved-caspase-8, Bcl-2, and FASN was investigated through western blot analysis. The viability and apoptosis of hESC-derived neurons were estimated through cell counting kit-8 assessment and TUNEL assay, accordingly. Superoxide dismutase, glutathione, and malondialdehyde levels were discovered via corresponding kits. The contents of inflammatory factors including interleukin-6 and tumor necrosis factor-α were examined by enzyme-linked immunosorbent assays. The combination between FASN and miR-424-5p was resolute via dual-luciferase reporter assessment. After exposure to ISO, induced neurotoxicity and a decreased miR-424-5p production were identified in hESC-derived neurons. Upregulation of miR-424-5p repressed ISO-induced apoptosis and mitigated ISO-induced inflammatory response and oxidative stress in vitro. FASN expression levels were reduced by elevation of miR-424-5p and upregulated after ISO treatment. Mechanically, FASN was directly targeted by miR-424-5p in hESC-derived neurons. Of note, the miR-424-5p elevation-suppressed neuronal apoptosis, inflammatory response, and oxidative stress were countered by upregulation of FASN.

P
<
0.05

), with the remarkably higher number of cured cases in the treatment group (

P
<
0.05

). After treatment, the treatment group had remarkably higher mean total active motion (TAM) and score of the 36-item short form (SF-36) health survey and a remarkably lower mean score of visual analog scale (VAS) than those in the control group (

P
<
0.001

). Conclusion. The quality of life and finger mobility of CTS sufferers can be improved with acupotomy in conjunction with electroacupuncture therapy. In-depth research will help build better procedures for these patients because this approach lessens the discomfort and shortens the symptom duration in CTS sufferers.

Published: July 2022

Lichens are a life form in which algae and fungi have a symbiotic relationship and have various biological activities, including anti‐inflammatory and antiproliferative activities. This is the first study to investigate the anti‐inflammatory activity of a Phlebia sp. fungal extract (PSE) isolated from Peltigera neopolydactyla in lipopolysaccharide‐ (LPS‐) stimulated RAW 264.7 macrophage. PSE reduced the production of the proinflammatory cytokine (tumor necrosis factor‐α, interleukin‐6, and interleukin‐1β), chemokine (granulocyte‐macrophage colony‐stimulating factor), nitric oxide, and prostaglandin E2 in the LPS‐stimulated RAW264.7 macrophages. Especially, PSE inhibits the phosphorylation of activator protein‐1 (AP‐1) signaling (c‐Fos and c‐Jun) and their upstream mitogen‐activated protein kinase kinases/mitogen‐activated protein kinases (MKK/MAPKs: MKK4, MKK7, and JNK) and finally reduced the production of the inflammatory cytokines. The inhibitory effects mainly act via suppressing JNK‐mediated AP‐1 rather than the NF‐κB pathway. Furthermore, PSE inhibited the production of final inflammatory effector molecules involved in AP‐1 signaling, including nitric oxide (NO) and prostaglandin E2 (PGE2). Here, we report that PSE has the potential to be developed as an anti‐inflammatory agent.
The Relevance of Virtual-Assisted Early Childhood Education and Occupational Psychotherapy Based on Emotional Interaction
Authors: Qie Dingran
Published: July 2022

This paper presents an in-depth study and analysis of the relevance of early childhood education to occupational psychotherapy using a virtual-assisted affective interaction approach. Starting from the educational theory of interactive cognitive psychology, the theoretical basis for parent-child picture book education for interactive learning is explored, as well as the theoretical development after the introduction of AR technology. Firstly, the analysis of young children’s emotions involves massive image processing, and the use of cloud computing architecture leads to high latency, while young children’s safety is a latency-sensitive service. Secondly, face recognition accuracy based on static images is not high due to problems such as inconspicuous facial features of toddlers and low-quality kindergarten surveillance videos. In this paper, a face identity correction model based on location features is proposed and the superiority of the model is demonstrated through experiments. Finally, this paper analyzes and mines the emotional data of young children. The level of kindergarten teachers’ awareness of early childhood mental health education generally showed an upward trend as their titles rose, and there were significant differences in the seven dimensions of early childhood mental health, the purpose and meaning of early childhood mental health education, implementers, targets, content, pathways, and effects; significant differences existed between teachers of different kindergarten natures, and there were significant differences in the purpose and meaning of early childhood mental health education, implementers, targets, content, pathways, effects, and mental health education for young children. Therefore, this paper proposes a face identity correction model based on position information, which considers both the correlation between pixel values in the spatial domain and the correlation between frames in the temporal domain. This paper has developed an emotion analysis system for kindergartens and put it into use in kindergartens to meet the needs of monitoring the safety of young children and evaluating early childhood education and has received good feedback from users, demonstrating the effectiveness of the system.

Authors: Li Mengjie , Liang Qianchao , Hu Jinyi , Liang Yifan , Zhao Jianfeng
Published: July 2022

In order to address the issue of multi-energy system fuel cells having a short life cycle and low fuel efficiency, a Fuel Cell Hybrid Vehicle was developed. The goal of this research is to use wavelet transformation to simulate, evaluate, and regulate the multi-energy system of a fuel cell hybrid car. To begin, a hybrid model of the fuel cell and an overall dynamic model of the fuel cell, as well as a DC/DC converter model, are constructed in accordance with the simulation environment. Second, the hybrid vehicle system's power information is successfully captured, and the power signal acquired is processed using the wavelet transform. The fuel cell power control and the composite power supply's power allocation module are independently input into the hybrid system's low frequency and high frequency power requirements. PI control is used to regulate the power of the storage device in the hybrid power system, as well as the power settings of the output fuel cell and supercapacitor. The simulation results show that the power battery fluctuation range of the hybrid vehicle multi-energy system based on the wavelet transform proposed in this paper is significantly smaller than that of other methods, and the entire process operates at low power points. The results of the experiments suggest that the strategies given in this study can successfully extend the life of fuel cells while also lowering the overall fuel efficiency of the vehicle system.

Authors: Yao Wenji , Ruan Yue
Published: July 2022

At present, algorithm technology has achieved very rapid development, and it is more and more widely penetrated and applied in people’s production and life. Among them, product design based on intelligent algorithm has also been widely used. This technology plays an important role in promoting product innovation and design and contributes to the improvement and optimization of technology, showing very significant application benefits in the product design and development process of major enterprises. The application of intelligent algorithms in product design can not only make products more in line with customers’ usage habits, but also products blessed with intelligent algorithms often have more commercial value. Therefore, in order to enhance the added value of commodities, innovative design of products has become a must. Nanomaterials must have unique properties that are unmatched by general building materials, such as high surface activity, strong oxidation, and superparamagnetic. This article mainly studies design strategies from two aspects, namely the innovation of material properties and application methods, and introduces the properties of nanomaterials, their application status, and the existing problems. And it starts from the application of intelligent technology in nanomaterial products, innovative design, and development prospects, combined with actual cases, to find a feasible way for the development of innovative design and research of nanomaterial products. On this basis, it is proposed that the idea of expanding the design should reunderstand and reposition the product design of nanomaterials and make the design more acceptable to more consumers. New design ideas and methods such as adjusting material properties through intelligent algorithms provide certain assistance and support for the application of intelligent algorithms in product design innovation practice. Some completed application practices are also presented to illustrate the rationality of the application of intelligent algorithms in nanomaterial products. The results show that the crowd search algorithm has the highest optimization degree and has good stability and optimization effect, and its standard deviation is the lowest close to 0.

Authors: Hu Zhiyong
Published: July 2022

The development of educational information processes and information technology has made it possible to build a remote learning environment for English education. The application of fifth-generation communication (5G) has carried out revolutions in education for both teachers and students. In this study, an optimization approach is presented for English teaching mode to overcome the limits of current college English teaching settings and broaden the span of 5G technology. The proposed optimization technique varies from traditional college English teaching methods in that it integrates 5G, which considerably increases the communication of college English classes. Furthermore, the optimization technique can promote the standard of English teaching in several ways while completely and systematically following the teaching principle of “teach students according to their capabilities.” In addition, a Bat Optimization Algorithm (BOA) is employed to enhance the process of transmission and measure the students’ cognitive skills. The experimental results show that the proposed method addresses the limitations of the traditional English teaching model in colleges while enhancing students’ cognitive skills in a variety of areas, including listening, speaking, reading, and writing.

To observe the clinical effect of minimally invasive percutaneous pedicle screw internal fixation combined with injured vertebrae bone grafting in the treatment of thoracolumbar fractures in orthopedic surgery. Methods. A total of 132 patients with thoracolumbar fractures admitted to the hospital were enrolled between January 2020 and April 2021. Both groups underwent minimally invasive percutaneous pedicle screw internal fixation. According to the presence or absence of intraoperative injured vertebrae bone grafting, they were divided into the grafting group (73 cases) and the injured vertebrae ungrafted group (59 cases). The perioperative indexes, pain at 2 weeks after surgery, surgical stress, recovery of an injured vertebra, self-care ability, quality of life, and postoperative complications were compared between the two groups. Result. There was no significant difference in intraoperative blood loss, operation time, or hospitalization time between the grafting group and the nongrafting group (

P
>
0.05

).2 weeks after surgery, scores of the Visual Analogue Scale (VAS) in the grafting group were lower than those in the nongrafting group (

P
<
0.05

).At 3d after surgery, levels of serum cortisol (COR), epinephrine (E), and norepinephrine (NE) in both groups were higher than those before surgery, which were lower in the grafting group than in the nongrafting group (

P
<
0.05

).At 3 months after surgery, the anterior edge height of the injured vertebra in both groups was increased, which was higher in the grafting group than in the nongrafting group (

P
<
0.05

). At 3 months after surgery, the Cobb angle of sagittal kyphosis in both groups was decreased, which was lower in the grafting group than that in the nongrafting group (

P
<
0.05

). At 3 months after surgery, the scores of activity of daily living (ADL) and the MOS item-short form health survey (SF-36) in both groups were higher than those before surgery, which were higher in the grafting group than in the nongrafting group (

P
<
0.05

). The difference in the incidence rate of injured vertebrae collapse, internal fixation breakage, or kyphosis between the grafting group and the nongrafting group was not statistically significant (1.37% vs 6.78%) (

P
>
0.05

). Conclusion. Minimally invasive percutaneous pedicle screw internal fixation combined with injured vertebrae bone grafting in orthopedic surgery can improve postoperative pain and surgical stress in patients with thoracolumbar fractures, which is conducive to the recovery of injured vertebrae and improvement in the quality of life.

The mystery of China’s economic growth has been widely concerned by the world. However, little attention has been paid to the transformation of the economic growth momentum of Guangdong Province, which has long occupied the top in China’s economic growth. This paper analyzes the evolution and the transformation of the momentum source of economic growth in Guangdong Province from 1979 to 2019, using Total Factor Productivity Growth Decomposition method. The results show that capital investment contributes the most to economic growth, the contributions of total factor productivity, and labor input rank second and third, respectively; the change of the contribution of each momentum source to GDP growth mainly comes from the impact of the secondary industry. Both industrial capital productivity and capital allocation structure play a negative role in driving the overall capital productivity, and both industrial labor productivity and labor allocation structure play a positive role in driving the overall labor productivity. Industrial factor productivity and industrial factor allocation structure play a major positive role and a weak negative role in promoting economic growth, respectively. Our findings provide some ideas on how to maintain economic growth in the new era especially for the developing countries.

Drug repositioning and drug reuse are the heated topics in the field of oncology in recent years. These two concepts refer to seeking effective drugs for cancer that are not originally intended to treat cancer. The survival benefits are then analyzed by combining the re-positioned drugs with conventional cancer treatment methods. Simvastatin is a clinically commonly used hyperlipidemia drug and exerts the effect of preventing cardiovascular diseases. Recent studies have found that simvastatin has great potential in the treatment of colorectal cancer, and a large number of clinical studies have used simvastatin as an adjuvant drug to help treat metastatic colorectal cancer.

In order to realize the automation and intelligence of agricultural equipment mechanical state detection and improve the efficiency and accuracy of agricultural machinery equipment detection technology, this paper proposes an intelligent agricultural machinery equipment state detection method based on computer data mining. This method uses support vector machine to classify the equipment status and uses ant colony algorithm to solve the optimization problem. Its basic logic is to collect the status data of agricultural machinery equipment, extract the status detection characteristics of agricultural machinery equipment, and use computer data mining to establish an automatic state detection model of agricultural machinery equipment. The application results show that the correct rate of the state detection of agricultural machinery equipment is more than 95%, and the false detection rate of the state of agricultural machinery equipment is far lower than that of other current state detection methods of agricultural machinery equipment. Conclusion. This method can realize high-precision real-time detection of agricultural machinery equipment and has higher practical value.

Published: July 2022

In order to study the law and mechanism of fault activation induced by deep continuous mining, this paper takes the fault activation caused by underground mining of Shizishan Copper Mine as the research object. On the basis of field investigation and theoretical analysis of fault activation, the law and mechanism of fault group activation induced by deep continuous mining in the Shizishan mining area are analyzed in detail based on the three-dimensional discrete element method software 3DEC. The results show that the fault effect of rock movement in the footwall of the main orebody in the mine area is obvious. The en echelon steep dipping fault group in the footwall of the goaf will move each fault block in the direction of the goaf and slip along the fault plane when the balance between mining and gravity is disrupted. The fault activation has a domino effect in time and space, and the mechanism of this effect is revealed. The research results have great significance for the deep mining area development, mining alignment arrangement, and disaster prevention and control caused by fault activation.

Objective. The objective of this study was to estimate the time between removal of cerclage and delivery, stratified by indication for cerclage placement (elective or non-elective). Additionally, delivery within 72 hours after cerclage removal was compared between elective and non-elective cerclage placement, as well as between ultrasound-indicated and physical examination-indicated cerclage placement. Design. A single-center retrospective cohort study. Participants/Materials, Setting, and Methods. Clinical information of 72 pregnant women who underwent transvaginal cerclage over a 4-year period was obtained. Comparisons were made between elective (history-indicated) and non-elective (ultrasound or physical examination-indicated) cerclage placement. Comparisons were also made between physical examination-indicated and ultrasound-indicated cerclage. Results. Compared to those who had a non-elective cerclage, women undergoing elective cerclage were more likely to have history of cervical treatment (44% vs. 15%,

p
=
0.02

), and spontaneous preterm delivery (92% vs. 61%,

p
=
0.003

). There was no difference in the rate of delivery ≤72 hours following cerclage removal between women who had elective cerclage and those who had non-elective cerclage (46% vs. 58%,

p
=
0.47

). Women who had an elective cerclage were more likely to have elective cerclage removal ≥36 weeks (71.8% vs. 39.4%,

p
=
0.01

), compared to those who had undergone non-elective cerclage. The rate of delivery ≤72 hours following removal of cerclage was greater in women who had a physical examination-indicated cerclage compared to women who had ultrasound-indicated cerclage (80% vs. 39%,

p
=
0.04

). Among women who had an elective cerclage, there was no difference in the rate of delivery at ≤72 hours between those who had elective cerclage removal at 36 weeks compared to those electively removed at 37 weeks (31% vs. 58%,

p
=
0.30

). No complications such as fetal demise, iatrogenic amniotic membrane rupture, hemorrhage, or cervical laceration were reported within this cohort. Conclusion. Cerclage indication should be considered prior to scheduling elective cerclage removal. Women who had an elective cerclage are most likely to get it electively removed at 36 weeks compared to their counterparts who had a non-elective cerclage. Furthermore, women who had a physical examination-indicated cerclage are most likely to deliver within 72 hours of cerclage removal.
