Published: July 2022

We present ASSET, a neural architecture for automatically modifying an input high-resolution image according to a user's edits on its semantic segmentation map. Our architecture is based on a transformer with a novel attention mechanism. Our key idea is to sparsify the transformer's attention matrix at high resolutions, guided by dense attention extracted at lower image resolutions. While previous attention mechanisms are computationally too expensive for handling high-resolution images or are overly constrained within specific image regions hampering long-range interactions, our novel attention mechanism is both computationally efficient and effective. Our sparsified attention mechanism is able to capture long-range interactions and context, leading to synthesizing interesting phenomena in scenes, such as reflections of landscapes onto water or fora consistent with the rest of the landscape, that were not possible to generate reliably with previous convnets and transformer approaches. We present qualitative and quantitative results, along with user studies, demonstrating the effectiveness of our method. Our code and dataset are available at our project page: https://github.com/DifanLiu/ASSET
Compatible intrinsic triangulations
Authors: Takayama Kenshi
Published: July 2022

Finding distortion-minimizing homeomorphisms between surfaces of arbitrary genus is a fundamental task in computer graphics and geometry processing. We propose a simple method utilizing intrinsic triangulations, operating directly on the original surfaces without going through any intermediate domains such as a plane or a sphere. Given two models A and B as triangle meshes, our algorithm constructs a
Compatible Intrinsic Triangulation
(CIT), a pair of intrinsic triangulations over A and B with full correspondences in their vertices, edges and faces. Such a tessellation allows us to establish consistent images of edges and faces of A's input mesh over B (and vice versa) by tracing piecewise-geodesic paths over A and B. Our algorithm for constructing CITs, primarily consisting of carefully designed edge flipping schemes, is empirical in nature without any guarantee of success, but turns out to be robust enough to be used within a similar second-order optimization framework as was used previously in the literature. The utility of our method is demonstrated through comparisons and evaluation on a standard benchmark dataset.
EMBER

Published: July 2022

Boolean operators are an essential tool in a wide range of geometry processing and CAD/CAM tasks. We present a novel method, EMBER, to compute Boolean operations on polygon meshes which is exact, reliable, and highly performant at the same time. Exactness is guaranteed by using a plane-based representation for the input meshes along with recently introduced homogeneous integer coordinates. Reliability and robustness emerge from a formulation of the algorithm via generalized winding numbers and mesh arrangements. High performance is achieved by avoiding the (pre-)construction of a global acceleration structure. Instead, our algorithm performs an adaptive recursive subdivision of the scene's bounding box while generating and tracking all required data on the fly. By leveraging a number of early-out termination criteria, we can avoid the generation and inspection of regions that do not contribute to the output. With a careful implementation and a work-stealing multi-threading architecture, we are able to compute Boolean operations between meshes with millions of triangles at interactive rates. We run an extensive evaluation on the Thingi10K dataset to demonstrate that our method outperforms state-of-the-art algorithms, even inexact ones like QuickCSG, by orders of magnitude.
Process Optimization to Avoid Perfluorocarbon Emission During Neodymium Rare Earth Electrolysis in Molten LiF-NdF3-Nd2O3
Authors: Gibilaro M. , Remazeilles C. , Massot L. , Chamelot P.
Published: July 2022

Influence of Nd2O3 in LiF-NdF3-Nd2O3 melt on carbon anode oxidation was investigated by infra-red spectroscopy and electrochemical techniques to prevent CFX(g) formation during Nd metal production. A gas extractor device was developed to provide fast analysis of the electrochemically produced gas: the carbon anode was only oxidized into CO2(g) until a critical current density was reached. For higher values, CF4(g) and C2F6(g) were also produced. It was associated to diffusion limited current density of NdOF5
4−. To avoid CFX(g) production during the process, the influence of Nd2O3 and temperature on this limiting current density was determined by steady-state voltammetry.
Direct Electrochemical Detection of Glucose on PEDOT Functionalized Screen-Printed Electrodes
Authors: Chen Junhao , Nilghaz Azadeh , Chen Xinyu , Liu Shan , Tian Junfei
Published: July 2022

This study reports a novel strategy to fabricate a third-generation glucose sensor on screen-printed carbon electrode (SPCE). The direct electron transfer (DET) between glucose oxidase (GOx) and SPCE was accomplished by immobilization of GOx in poly (3, 4-ethylenedioxythiophene) (PEDOT) functionalized electrodes. The use of PEDOT relaxed the requirement for the distance between the redox site of GOx, flavin adenine dinucleotide (FAD) cofactors, and the electrodes in the DET process due to its low ionization potential and good hole-injection ability. This strategy has not required the introduction of an additional mediated agent, and the response current of glucose consisted of DET current. The developed sensor demonstrated high electrochemical responses of glucose in human blood plasma with a wide linear range of 1–14 mM l−1. The reproducibility of the sensor (electrodes) was also studied by sequential determinations of glucose under analogous parameters over time, showing no significant decrease in the faradic response. The construction of DET process with facile methods (3 steps of drop-coating), and simultaneously, the fundamental SPCE does not need any activation process, which makes large mass production of third-generation biosensing systems possible.

Authors: Bai Xuyang , Li Shaolong , He Jilin , Song Jianxun
Published: July 2022

In the process of molten salt electrolysis, the influence of the composition of the electrolyte on the current efficiency and electrolysis quality is a key issue that needs to be studied urgently. Thus, the interaction between tantalum ions and anions, coordination competition between chlorine ions and fluoride ions in the electrochemical metallurgy of tantalum metal are investigated in this paper. Their effects on the reduction mechanism of tantalum ions was also studied. Moreover, the chemical coordination mechanism of tantalum ions in the above molten salts were revealed through electrochemical tests and chemical analysis. By adding fluoride ions, the reduction step of tantalum ions is reduced from two-step to one-step, which simplifies the reduction process, avoids the current empty consumption caused by the disproportionation reaction of low-valent tantalum ions, and optimizes the particle size of the product.

Authors: Yitzhack Neta , Ein-Eli Yair
Published: July 2022

The electrodeposition of copper particles inside carbon nanotube (CNT) tissues is presented here. Copper electrodeposition inside CNT from aqueous electrolytes has been challenging researchers in recent years, as deposition was mostly restricted to the external surface of the tissue. This work introduces several organic additives, promoting deposition inside the tissue, as well. Electrochemical methods were applied and utilized in order to study the behavior of the CNT in the plating bath, and to analyze the effect of different additives on the deposition of the copper particles. Surface morphology of the coating and the deposits inside the tissue were examined and studies. This work presents an alternative method for the deposition and implementation of copper crystals inside CNT tissue.

Published: July 2022

In silicon heterojunction (SHJ) solar cells, a wide bandgap material with a high work function is widely used as the hole extraction pathway to attain high efficiency. We introduced a molybdenum oxide (MoOx) film as an effective hole-transfer layer in carrier selective contact (CSC) solar cells by virtue of its wide bandgap along with high work function. The passivation characteristics, optical and electrical properties of MoOx films were investigated by differing thickness and work function. The combination of 6 nm hydrogenated intrinsic amorphous silicon (a-Si:H(i)) and 7 nm thermally evaporated MoOx passivation layers provides excellent passivation properties, reduces carrier recombination, and improves the cell performance. The synthesized CSC solar cells showed promising results, with an open-circuit voltage (Voc) of 708 mV, short-circuit current (Jsc) = 37.38 mA cm−2, fill factor (FF) = 74.59%, and efficiency (η) = 19.75%. To justify the obtained result, an AFORS HET simulation was conducted based on the experimental results. The high work function and wide bandgap MoOx/c-Si(n) interface developed a considerable built-in potential and suppressed the electron–hole pair recombination mechanism. The CSC solar cell’s simulated performance was enhanced from 1.62 to 23.32% by varying the MoOx work function (ΦMoOx) from 4.5 to 5.7 eV.
Ischemic damage to every segment of the oxidative phosphorylation cascade elevates ETC driving force and ROS production in cardiac mitochondria
Authors: Kuzmiak-Glancy Sarah , Glancy Brian , Kay Matthew W.
Published: July 2022

This integrative analysis is the first to assess how myocardial ischemia alters the mitochondrial driving forces and the degree to which individual segments of the mitochondrial energy transduction pathway contribute to diminished function following ischemia. This investigation demonstrates that increased reactive oxygen species production following ischemia is related to a lower effective activity of the electron transport chain and a greater driving force down the electron transport chain.
Mixed lineage kinase 3 requires a functional CRIB domain for regulation of blood pressure, cardiac hypertrophy, and left ventricular function
Authors: Liu Pei-Wen , Martin Gregory L. , Lin Weiyu , Huang Wanting , Pande Suchita , Aronovitz Mark J. , Davis Roger J. , Blanton Robert M.
Published: July 2022

Here, we identified that the presence of two discrete point mutations within the Cdc42/Rac interaction and binding domain of the protein MLK3 recapitulates the effects of whole body MLK3 deletion on blood pressure, cardiac hypertrophy, and left ventricular compensation after pressure overload. These findings implicate the CRIB domain, and thus MLK3 activation by this domain, as critical for maintenance of cardiovascular homeostasis.
Sympathoexcitatory responses to renal chemosensitive stimuli are exaggerated at nighttime in rats
Authors: DeLalio Leon J. , Stocker Sean D.
Published: July 2022

The current study discovers that the circadian cycle influences sympathetic and hemodynamic responses to activation of renal chemosensitive sensory fibers. Sympathetic responses to intrarenal bradykinin or capsaicin infusion were exaggerated during nighttime (active period), but mechanosensitive responses to elevated renal pelvic pressure were not. Importantly, renal afferent nerve responses were not different between nighttime and daytime. These data suggest that the circadian cycle modulates sympathetic responses to visceral afferent activation.

Published: July 2022

In this paper, through the in-depth study of advanced intelligent extensive data analysis and the design of the model of the environment design automatic layout intelligent sensor network, we realize the environment design intuitive layout smart sensor network based on advanced thoughtful and extensive data analysis. According to the non-beacon-enabling CSMA/CA algorithm of the MAC layer of a single node in intelligent sensor network, the analysis model of the node MAC layer of the innovative sensor network based on the Markov chain is established. The mathematical calculation method of node MAC layer delay is obtained through the analysis and calculation of nodes’ Markov state transfer process in this model. By analyzing the internal composition of design grooming, data support, analysis modeling, and platform in environmental design big data and the relationship between each part, the industrial extensive data analysis modeling method system is formed based on the CRISP-DM model, based on which the demand analysis of the industrial comprehensive data analysis modeling platform is carried out, and the overall architecture of the platform is formed; this paper proposes an automatic layout algorithm based on strategy iteration for each. Each type of environment design is modeled, and the layout scheme is sequentially generated. The applicability, aesthetics, and comfort are considered, but the design information provided by the space contour can be regarded to develop a reasonable layout scheme. The experimental results show the rationality and versatility of the automatic layout schemes, proving the practicality and time-saving nature of the work.

Published: July 2022

In order to study the clinical application value of placenta accreta (PIA) diagnosis and grading, the authors propose a method based on ultrasound combined with magnetic resonance imaging in the diagnosis and grading of prenatal placenta accreta patients. This method is adopted in materials and methods: a retrospective analysis of hospital patients with high suspicion of placenta accreta by clinical or ultrasonography between October 2019 and October 2021, the imaging and clinical data of 312 patients who underwent placental MRI examination. The MRI imaging data of all patients were jointly analyzed, and the main observation indicators are as follows: (1) dark zone in the placenta, (2) disruption of the border of the myometrium, (3) disruption of the myometrium, (4) abnormal blood vessels in the placenta, (5) enlargement of the lower part of the uterus, and (6) local bulge of the bladder/or invasion of the adjacent tissues of the uterus. The results show the following: in MRI combined with ultrasonography (

P
<
0.05

), there was no statistical significance in the specificity and accuracy of MRI combined with ultrasound to diagnose PIA (

P

The objective is to compare the clinical efficacy of laparoscopic resection (LAP), endoscopic full-thickness resection (EFR), and endoscopic submucosal dissection (ESD) in the treatment of gastrointestinal stromal tumors. Methods. The clinical data of 105 patients who were treated in our hospital and diagnosed with GIST by pathology after surgery from March 2019 to March 2021 were collected. Patients were divided into the LAP group, EFR group, and ESD group according to different surgical methods. The clinical data, surgical conditions, complications, and postoperative conditions of the patients were recorded retrospectively. Patients were followed up closely after surgery. Results. The operation time of the EFR group and ESD group was shorter than that of the LAP group, and the operation time of the EFR group was shorter than that of the ESD group (

P
<
0.05

). The amount of intraoperative blood loss in the EFR group and ESD group was lower than that in the LAP group (

P
<
0.05

). There was no significant difference in the complete resection rate among the three groups (

P
>
0.05

). There was no significant difference in the total incidence of complications among the three groups (

P
>
0.05

). The postoperative abdominal pain time, postoperative hospital stay, and total hospitalization costs of the EFR group and ESD group were lower than those of the LAP group (

P

But compared with LAP, EFR and ESD have the advantages of less trauma, faster recovery, shorter hospitalization time, and lower hospitalization cost.
A Novel Computational Tool for the Fractional-Order Special Functions Arising from Modeling Scientific Phenomena via Abu-Shady–Kaabar Fractional Derivative
Authors: Abu-Shady M. , Kaabar Mohammed K. A.
Published: July 2022

Recently, a generalized fractional derivative formulation, known as Abu-Shady–Kaabar fractional derivative, is studied in detail which produces satisfactory results that are consistent with conventional definitions of fractional derivative such as Caputo and Riemann-Liouville. To derive the fractional forms of special functions, the generalized fractional derivative is used. The findings demonstrate that the current findings are compatible with Caputo findings. In addition, the fractional solution to the Bessel equation is found. While modeling phenomena in engineering, physical, and health sciences, special functions can be encountered in most modeling scenarios related to electromagnetic waves, hydrodynamics, and other related models. Therefore, there is a need for a computational tool for computing special functions in the sense of fractional calculus. This tool provides a straightforward technique for some fractional-order special functions while modeling these scientific phenomena in science, medicine, and engineering.
The Effect of TCM Syndrome Type and Western Medicine Detection on Patients with Hypertension and Diabetes Mellitus
Authors: Chen Ruqin , Zhang Min , Zhang Yanqing
Published: July 2022

Objective. To investigate the clinical changes of TCM syndrome type and microalbuminuria in patients with hypertension and diabetes mellitus. Methods. A total of 442 patients with hypertension and diabetes who were admitted to our hospital from June 2016 to June 2021 were selected. All patients were divided into medication group and control group according to the random number method. Patients in the medication group were treated with conventional Western medicine-assisted traditional Chinese medicine, while patients in the control group were not treated with adjuvant medicine. The blood pressure and blood glucose of patients in the two groups were controlled within the normal range, and the clinical effects of the two groups were observed. Results. The treatment of hypertension and diabetes in the two groups was diagnosed by the TCM syndrome type, and the cure rate was higher in the medication group. After 3 months, the glomerular filtration rate in the medication group increased steadily and the renal artery resistance index decreased, while the indexes in the control group had no significant change, with statistical significance (

P
<
0.05

). After 6 months, the urinary albumin excretion rate and the ratio of urinary albumin to creatinine in the medication group were significantly decreased compared with those before medication, while there were no significant changes in the control group, with statistical significance (

P
<
0.05

). The urine excretion rate of albumin in hypertensive patients with diabetes is higher, leading to the increased probability of microalbuminuria in patients, which is not only related to the course of hypertension and diabetes but also positively related to the course of hypertension and diabetes, smoking, drinking, and diet. Conclusion. The combination of the TCM syndrome type and Western medicine detection method is more conducive to the two diagnosis and treatment methods that complement each other, improve each other, improve the effect of diagnosis and treatment, and are worthy of further research by researchers, so as to promote clinical application. Some other bad habits should also be corrected, such as smoking, drinking, and irregular diet, through adjusting the diet; control of high protein intake is also an important intervention measure for disease.

Authors: Liu Ming , Xue Renzheng , Li Xiaoye
Published: July 2022

In order to solve the practical problem that the massive video data generated by monitoring equipment cannot be processed efficiently temporarily, this paper proposes a framework for face recognition of massive video data based on distributed environment. Combined with the application features of face recognition, this method designs a strategy for fast reading of massive video data and optimizes the feature data obtained by the cloud platform, so as to speed up the retrieval speed of face features. The results are as follows: the compression rate of the proposed compression method is higher than that of the traditional matrix triple and binary methods, which is increased by about 65%; the data optimization method in this paper greatly reduces the amount of feature data, which is 7.08 times less than that in the nonoptimization state. At the same time, the process of face recognition is reduced from 12.6 seconds to 2.73 seconds, and the time of feature decompression is only 0.75 seconds more than the original; the experiment shows that it takes 10180 seconds for the system to process 200 GB pictures with 9 computing nodes, and the total running time of the system is 4737 seconds longer than that of a single node, accounting for about 5.45% of the total time of a single node system. At the same time, the experimental data show that the system is 8.53 times faster than that of a single node with 9 computing nodes. It is proved that this framework has certain research significance in dealing with massive unstructured data. It not only provides theoretical reference value for the research of massive video processing but also makes a contribution to the actual industry.
Meta-Analysis of Predictive Role of Early Neurological Deterioration after Intravenous Thrombolysis
Authors: Jiang Haiwei , Zuo Jing , Wang Dan , Huang Yi , Gao Chang , Wan Yue
Published: July 2022

With the popularization of intravenous thrombolysis, more and more people use intravenous thrombolysis to treat related diseases, but problems also arise. There are still a considerable number of patients with early disease after thrombolytic therapy not only not significantly improving, but also progressing, that is, early neurological deterioration (END). In view of this problem, the prediction of END after intravenous thrombolysis becomes very important. With the development of medical technology, research on the prediction of END after intravenous thrombolysis has gradually been carried out. Effective prediction is of great significance for the prevention and treatment of END after intravenous thrombolysis. This article aimed to carry out a meta-analysis of the predictive role of END after intravenous thrombolysis. Through an informed analysis of all studies of this type in this field, this article determines a method for predicting END after intravenous thrombolysis. The actual effect of its role is revealed in this paper, and its purpose is to promote the development of this field. This article addresses the same type of study on the predictive role of neurological deterioration after intravenous thrombolysis. The article performs test and meta-analysis of its role by conditionally searching for literature studies. It is explained using the relevant theoretical formulas. The analysis results show that the prediction of END after intravenous thrombolysis in this paper can effectively help make a preliminary judgment on the possible later neurological deterioration. Although there is an error between the predicted curve and the actual curve, the difference between the two is between 1% and 5%. It can basically effectively predict the occurrence of END. Therefore, the prediction of END after intravenous thrombolysis has a very large preventive effect on the END after intravenous thrombolysis.

Published: July 2022

Objective. The Amplatzer patent foramen ovale (PFO) occluder is the most commonly used device for percutaneous closure of a large PFO. However, its use may predispose the patient to postoperative residual shunting. To reduce the incidence of residual shunting, we investigated the safety and effectiveness of the Amplatzer atrial septal defect (ASD) occluder for percutaneous closure of a large PFO measured by transesophageal echocardiography (TEE) and evaluated the value of TEE in this procedure. Methods. Overall, 118 patients who were diagnosed with a large PFO (all with

a
≥
2

 mm left atrial side height after the Valsalva maneuver (VM) excluding those with a small ASD) using contrast transthoracic echocardiography (c-TTE) and TEE underwent closure under TEE guidance at The First Affiliated Hospital of Xi’an Jiaotong University. An ASD device was used in 48 patients (group I) and a PFO device in 70 (group II). After the procedure, we verified the safety and efficacy of different devices using c-TTE, TTE, and TEE. Results. In both groups, the preoperative TEE results showed a significantly increased left height of the PFO after VM compared with that at rest (all

P
<
0.01

). Compared with the left height of the PFO measured using TEE after VM, the PFO-stretch diameter (SD) measured by TEE after the delivery sheath passed the PFO was higher (all

P
<
0.01

). We selected the ASD occluder size according to this PFO-SD. In group II, most patients underwent the implantation of the larger PFO devices. Interventional treatment was successfully performed on all patients. The effective occlusion rate in group I at 12 months after the procedure was significantly higher than that in group II (93.7% vs. 78.6%,

P
<
0.05

). The TEE results showed that 18 patients with a medium and large residual shunt at 12 months after the procedure exhibited an intradisc tunnel-like shunt. Conclusion. The Amplatzer ASD device and Amplatzer PFO device are safe for large PFO closure, but the Amplatzer ASD device has a higher effective occlusion rate. TEE plays a crucial role in the use of the Amplatzer ASD occluder for percutaneous closure of a large PFO.

Published: July 2022

With the development of artificial intelligence, the application of intelligent algorithms to low-power embedded chips has become a new research topic today. Based on this, this study optimizes the YOLOv2 algorithm by tailoring and successfully deploys it on the K210 chip to train the face object detection algorithm model separately. The intelligent fan with YOLOv2 model deployed in K210 chip can detect the target of the character and obtain the position and size of the character in the machine coordinates. Based on the obtained information of character coordinate position and size, the fan's turning Angle and the size of air supply are intelligently perceived. The experimental results show that the intelligent fan design method proposed here is a new embedded chip intelligent method of cutting and improving the YOLOv2 algorithm. It innovatively designed solo tracking, crowd tracking, and intelligent ranging algorithms, which perform well in human perception of solo tracking and crowd tracking and automatic air volume adjustment, improve the accuracy of air delivery and user comfort, and also provide good theoretical and practical support for the combination of AI and embedded in other fields.
Theoretical Study of the Structural, Optoelectronic, and Reactivity Properties of N-[5′-Methyl-3′-Isoxasolyl]-N-[(E)-1-(-2-)]Methylidene] Amine and Some of Its Fe2+, Co2+, Ni2+, Cu2+, and Zn2+ Complexes for OLED and OFET Applications

Published: July 2022

Herein, we report the structural, electronic, and charge transfer properties of N-[5′-methyl-3′-isoxasolyl]-N-[(E)-1-(-2-thiophene)] methylidene] amine (L) and its Fe2+, Co2+, Ni2+, Cu2+, and Zn2+ complexes (dubbed A, B, C, D, and E, respectively) using the density functional theory (DFT). All molecules investigated were optimized at the BP86/def2-TZVP/RI level of theory. Single point energy calculations were carried out at the M06-D3ZERO/def2-TZVP/RIJCOSX level of theory. Reorganization energies of the hole and electron (λh and λe) and the charge transfer mobilities of the electron and hole (μe and μh) have been computed and reported. The λe and λh values vary in the order D > E > A > B > C > L and E > A > D > L > C > B, respectively, while μe and μh vary in the order B > C > L > A > E > D and C > B > A > L > E > D, respectively. μh of B (39.5401 cm2·V−1S−1) and C (366.4740 cm2·V−1s−1) is remarkably large, suggesting their application in organic light-emitting diode (OLED) and organic field-effect transistor (OFET) technologies. Electron excitation analysis based on time-dependent (TD)-DFT calculations revealed that charge transfer excitations may significantly affect charge transfer mobilities. Based on charge transfer mobility results, B and C are outstanding and are promising molecules for the manufacture of electron and hole-transport precursor materials for the construction of OLED and OFET devices as compared to L. The results also show that L and all its complexes interestingly have higher third-order NLO activity than those of para-nitroaniline, a prototypical NLO molecule.

Objective. To investigate the efficacy and safety of endoscopic tympanic membrane catheterization and ofloxacin ear drops in the treatment of secretory otitis media in infants and toddlers. Methods. A total of 80 children suffering from secretory otitis media who underwent treatment in our hospital from July 2018 to April 2020 were divided into the control group (n = 40) and experimental group (n = 40) by randomization. The control group was treated with endoscopic tympanic membrane catheterization alone, while the experimental group was treated with ofloxacin ear drops based on the same treatment as the control group. The treatment effect, air conduction hearing level, clearance rate of pathogenic bacteria secreted by the ear canal, recurrence rate, and adverse reactions were compared between the two groups.

P
<
0.05

). After treatment, a substantially improved air conduction hearing level in the experimental group was observed (

P
<
0.001

). A chi-square test showed a significantly higher clearance rate of pathogenic bacteria secreted from the ear canal of the children in the experimental group compared to that of the control group (

P
<
0.05

). The treatment in the experimental group resulted in a lower recurrence rate and adverse reaction rate as compared to the control group (

P
<

Published: July 2022

Purpose. Real-world evidence refers to patient data derived from the healthcare process. In this study, we used National Health Insurance Research Database (NHIRD) assessments and clinical studies of Ge Gen Tang (GGT, 葛根湯) in patients with common cold to establish a real-world study model of Traditional Chinese Medicine formulae. GGT is widely prescribed for the treatment of common cold in Taiwan, generally in combination with other medicines. The aim of this study was to determine whether a correlation exists between GGT combined with other medicines and an improvement in cold symptoms. We also established a GGT prescription compatibility system by analyzing Taiwan’s NHIRD records for GGT prescription patterns in patients with different types of common cold. Materials and Methods. We extracted and analyzed records from the NHIRD for the period 2000–2015 to determine the most common clinical applications of GGT. GGT and GGT with Chuan Xiung Cha Tiao San were most commonly prescribed for common cold, as per NHIRD recommendations. Records for adults aged 20–65 years who were prescribed GGT for the treatment of common cold (Diagnosis Code ICD-9-460) were included in this study. We assessed the following indicators of the common cold, before and after treatment with GGT: nasal congestion, cough, runny nose, sneezing, sore throat, hoarseness, stiff shoulder, headache, and general physical condition. Results. The cold symptom scores before and after taking the GGT prescriptions significantly differed in the 29 volunteers. The 29 volunteers reported a significantly lower headache severity score after medication than before medication (

p
<
0.004

). Furthermore, patient scores for general physical condition decreased significantly (

p

Authors: Liu Shasha
Published: July 2022

As a body movement art, dance has its special form of expression. In terms of dance vocabulary, it can be roughly divided into two parts: external body movement and internal modality. In the process of body movement, it conveys information through silent language and the audience directly feels the information given by the dance image through vision. This is the special way of expressing emotion and meaning in dance art. This paper combines artificial intelligence technology and BP neural network (BPNN) algorithm to intelligently control dance teaching and solve complex nonlinear control problems. This paper studies dance teaching based on artificial intelligence technology. In this paper, BPNN algorithm and PCA‐BPNN algorithm are used to test the dance teaching training of dance language, dance music, and stage art. The average accuracy of the BPNN evaluation model is 85.35% when the time reaches 80, while the average accuracy of the PCA‐BPNN evaluation model is 65.64%. This shows that the accuracy of the BPNN evaluation model is higher than that of the PCA‐BPNN evaluation model. Under the artificial intelligence technology, the dance using BPNN algorithm brings more intense sensory stimulation to the viewer because of the accompaniment of music, so as to achieve the infection and enjoyment of beauty and achieve the harmonious unity of sports and art.

We aimed to evaluate how proximity to urban areas interferes with the relationship between socioeconomic variables and various aspects of medicinal plant knowledge. The study was conducted in six communities of the Catimbau National Park (PARNA Catimbau) in the state of Pernambuco. Eighty participants were interviewed. The communities were divided into two groups according to their distance from the nearest urban center. Socioeconomic data and information on medicinal plants were collected through semistructured interviews. Subsequently, generalized linear models were generated to verify the influence of the interaction between the variables on medicinal knowledge. We observed that proximity to the urban center influenced the relationship between the level of education and the knowledge of body systems treated by medicinal plants. We concluded that environmental variables can generate a differentiated effect on the influence of socioeconomic factors on one’s knowledge of medicinal plants.

The detection of moving objects by machine vision is a hot research direction in recent years. It is widely used in military, medical, transportation, and agriculture. With the rapid development of UAV technology, as well as the high mobility of UAVs and the wide range of high-altitude vision, the target detection technology based on UAV vision is applied to traffic management such as vehicle tracking and detection of vehicle violations. The moving target detection technology in this study is based on the YOLOv3 algorithm. It implements moving vehicle tracking by means of Mean-Shift and Kalman filtering. In this paper, the Gaussian background difference technology is used to analyze the illegal behavior of the vehicle, and the color feature extraction technology is used to identify and locate the license plate, and the information of the illegal vehicle is entered into the database. The experiment compares the moving target detection of UAV vision and the traditional target detection in four aspects: recognition accuracy, recognition speed, manual time, and divergent results. The results show that the average accuracy rates of UAV vision-based moving target detection and traditional pattern recognition are 98.4% and 87.8%, respectively. The recognition speeds are 24.9 (vehicles/sec) and 10.6 (vehicles/sec), respectively. However, the artificial time and divergence results of moving target detection based on UAV vision are only 1/3 of the traditional mode. The moving target detection based on UAV vision has a better moving target detection ability.

Atherosclerosis is a kind of chronic inflammatory cardiovascular disease. Epigenetic regulation plays a crucial role in atherosclerosis. Our study was aimed at finding potential biomarkers associated with the occurrence of atherosclerosis. Two datasets were downloaded from the Gene Expression Omnibus (GEO) database. The epigenome-wide association study (EWAS) analysis was performed on methylation data using CpGassoc package. The differential expression analysis was conducted on mRNA data using limma package. The GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) functional enrichment was done in clusterProfiler package. Finally, the logistic regression model was constructed using generalized linear model (glm) function. Between atherosclerotic vs. nonatherosclerotic samples, totally 4980 cytosine-phosphate-guanine (CpG) sites (annotated to 2860 genes) and 132 differentially expressed genes (DEGs) related to atherosclerosis were identified. The annotated 2860 genes and 132 DEGs were significantly enriched in 9 and 4 KEGG pathways and 289 and 132 GO terms, respectively. After cross-analysis, 6 crucial CpG sites were screened to build the model, including cg01187920, cg03422911, cg08018825, cg10967350, cg14473924, and cg25313204. The diagnostic model could reliably separate the atherosclerosis samples from nonatherosclerotic samples. In conclusion, the 6 CpG sites are probably potential diagnostic biomarkers for atherosclerosis, including cg01187920, cg03422911, cg08018825, cg10967350, cg14473924, and cg25313204.

Objective. To explore the clinical analysis of ear congestion after balloon Eustachian tuboplasty (BET) with or without tympanostomy tube insertion. Methods. A total of 35patients (49 affected ears) with ear congestion following BET with or without tympanostomy tube insertion were recruited from the hospitalized patients from January 2015 to December 2017. The score of Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) 15, visual analogue scale (VAS), and Valsalva scores were recorded before and after operation, and the influencing factors of prognosis were analyzed. The duration of follow-up was 1–4 years. Results. All patients showed significantly decreased average preoperative ETDQ-7 score, VAS, and Valsalva score after operation (

). The significance of the surgery types, course of disease, severity of tympanic membrane retraction, and tympanogram tracings classification as influencing factors of prognosis did not come up to the statistical standard (

p

). Conclusion. The patients showed relatively stable postoperative conditions after 3 years, and there were variations in the range of ETDQ-7 scores at 5 years postoperatively. Patients with levels I and II tympanic membrane retraction showed more favorable surgical effects. Surgical interventions are required for patients diagnosed with obstructive Eustachian tube dysfunction (ETD) after three months of conservative treatment without satisfactory results.
User Dynamic Preference Construction Method Based on Behavior Sequence

Published: July 2022

People’s needs are constantly changing, and the performance of traditional recommendation algorithms is no longer enough to meet the demand. Considering that users’ preferences change with time, the users’ behavior sequence hides the evolution and change law of users’ preferences, so mining the dependence of the users’ behavior sequence is extremely important to predict users’ dynamic preferences. From the perspective of constructing users’ dynamic preferences, this paper proposes a users’ dynamic preference model based on users’ behavior sequences. Firstly, the user’s interest model is divided into short-term and long-term interest models. The short-term interest reflects the user’s current preference, and the long-term interest refers to the user’s interest from all his historical behaviors, representing the user’s consistent and stable preference. Users’ dynamic preference is obtained by integrating short-term interest and long-term interest, which solves the problem that the user’s preference cannot reflect the change in the user’s interest in real-time. We use the public Amazon review dataset to test the model we propose in the paper. Our model achieves the best performance, with a maximum performance improvement of 15.21% compared with the basic model (BPR, NCF) and 2.04% compared with the sequence model (GRU4REC, Caser, etc.), which proves that the user’s dynamic preference model can effectively predict the user’s dynamic preference. Users’ dynamic preferences are helpful in predicting users’ real-time preferences, especially in the field of recommendation.

Published: July 2022

Background. A full-time dentist was assigned to a ward at our hospital to improve the quality of oral healthcare for hospitalized patients. A dental care system (DCS) was created to facilitate the collaboration between the full-time dentist and the nursing department. Objective. To investigate the effects of DCS implementation on the incidence of pneumonia in patients with acute stroke. Methods. This retrospective cohort study comprised 945 hospitalized acute stroke patients categorized into three groups: pre-, during-, and post-DCS. The DCS comprised dentist-led lectures and practical sessions, oral assessments, standardized oral care techniques, and information on the procedures for nurse-requested dental intervention. Data were extracted from the Japanese Diagnosis Procedure Combination database and medical records. The attributes of the patients, incidence of pneumonia, and number of patients who requested dental intervention were determined. Results. The odds ratios of pneumonia onset were 3.16 (95% confidence interval [CI], 1.65–6.05;

P
=
0.001

) in the pre-DCS and 2.80 (95% CI, 1.48–5.31;

P
=
0.002

) in the during-DCS group compared with the post-DCS group, thereby confirming the effect of DCS on the incidence of pneumonia. The number of dental requests in the post-DCS group was noted to be higher than that in the pre-DCS group (

P
=
0.002

). Conclusion. Oral management by a full-time dentist was found to be effective in reducing the incidence of pneumonia in patients with acute stroke. To implement the best oral care practices in the hospital wards, the full-time dentist should work as a member of the medical team.
