Authors: Zhao Xizhen , Chen Lingmin , Huang Feiri , Huang Zhihong , Zhou Huijie 
Published: March 2023

Objective: Enhanced Recovery after Surgery (ERAS) protocol has been developed and practiced for various surgical procedures to improve outcomes in the postoperative period. We hereby present our experience of ERAS for a large cohort of patients undergoing total joint arthroplasty (TJA).
Methods: We implemented the ERAS program at The Third Affiliated Hospital of Shanghai University from January 2020 and retrospectively compared outcomes of patients undergoing total knee or hip arthroplasty before and after the implementation of the program. ERAS protocol consisted of the use of patient education, blood management, multimodal analgesia, antiemetics, shorter fasting time, no patient-controlled analgesia, early physical therapy, and reduced use of catheters and drains.
Results: There were 94 patients in the study group (ERAS) and 113 patients in the control group (non-ERAS). We noted a statistically significant reduction in the incidence of postoperative nausea/vomiting, lowered pain scores, reduced length of hospital stay and better functional outcomes with both total knee and hip arthroplasties in our study cohort.
Conclusion: ERAS protocol can bae effectively implemented for patients undergoing TJA. The use of ERAS leads to better postoperative outcomes and shortened hospital stay.

Influencing factors of dexmedetomidine on postoperative myocardial protection in patients with Video-Assisted Thoracoscopic Surgery lobectomy: A retrospective cohort study
Authors: Li Hua , Liu Ji , Li Chun , Shi Hong 
Published: March 2023

Objective: To investigate factors affecting the cardioprotective proprieties of dexmedetomidine in patients after pulmonary lobectomy.
Methods: The data of 504 patients who received dexmedetomidine combined with general anesthesia and video-assisted thoracoscopic surgery (VATS) lobectomy in Shanghai Lung Hospital from April 2018 to April 2019 were analyzed retrospectively. Patients were divided into normal troponin group (LTG) and high troponin group (HTG) according to whether the postoperative troponin level was greater than 13. Ratio of systolic blood pressure greater than 180, heart rate greater than 110, the dose of dopamine and other drugs, the ratio of neutrophils to lymphocytes, postoperative visual analog scale (VAS) pain score and hospital stay were compared between the two groups.
Results: Preoperative systolic blood pressure, intraoperative maximum systolic blood pressure, intraoperative maximum heart rate, intraoperative minimum heart rate and N-terminal pro hormone brain natriuretic peptide (NT-proBNP) correlated with troponin values. The proportion of patients with systolic blood pressure greater than 180 in the HTG was higher than that in the LTG (p=0.0068), and the proportion of patients with heart rate greater than 110 was significantly higher in the HTG compared to the LTG (p=0.044). The ratio of neutrophils/lymphocytes in the LTG was lower than that in the HTG (P<0.001). At 24 and 48 hours after operation, the VAS score in the LTG was lower than that in the HTG. Patients with high troponin had longer hospital stay.
Conclusions: Intraoperative systolic blood pressure, maximum heart rate, and postoperative neutrophil/lymphocyte ratio are important factors that affect the myocardial protection properties of dexmedetomidine and may affect the postoperative analgesia effect and the length of hospital stay.

Authors: Popovych Andriy , Popovych Dariya , Ruzhylo Sofiya , Zakalyak Nataliya , Zukow Xawery , Shypytiak Yevstakhii , Fil Vitalij 
Published: March 2023

Background. There are several patented methods of preservation of medicinal waters of the Naftussya type. The authors of the patents as evidence of the correctness of the methods cite the facts of preservation of the ability of canned water to enhance motility rat’s v. portae in vitro and/or increase diuresis. However, such tests are not attributive. The most characteristic manifestation of the biological activity of Naftussya water is the stimulation of phagocytosis through the mediation of the nervous and endocrine systems. Another "Method of preservation of hydrogen sulfide mineral waters" was recently patented. The purpose of this study is to compare the impact of fresh and canned by this method Naftussya water on its targets in patients with chronic pyelonephritis. Materials and Methods. The object of clinical-physiological observation were residents of the city of Truskavets’ (21 men aged 24-67 years and 8 women 33-76 years) with chronic pyelonephritis in remission. The subject of the study were the phagocytic function of neutrophils, excretory function of kidneys, leukocyturia and bacteriuria levels, components of microbiota of feces as well as HRV and endocrine parameters. Results. Weekly use of fresh Naftussya water causes an increase in the reduced content of probiotics in the microbiota and a decrease in the increased content of conditionally pathogenic microflora, which is accompanied by an increase in reduced bactericidal capacity of neutrophils against both E. coli and Staph. aureus, normal diuresis, phosphaturia, magnesiumuria, ureauria while reduction of bacteriuria and leveling of leukocyturia as well as decrease in concentration of uric acid in urine and creatinine and cholesterol in plasma. Favorable changes in neuro-endocrine regulation were revealed. The beneficial effect on the listed parameters of canned Naftussya water is less pronounced, but the differences are statistically insignificant. Conclusion. The obtained results confirm the effectiveness of the Dovzhenko© method for Naftusya water conservation and provide grounds for continuing research into the effects of canned Naftusya water on the body of urological patients.

The Klein-Gordon-Maxwell system is a model describing solitary waves for the nonlinear Klein-Gordon equation interacting with an electromagnetic field. By using variational methods and some analysis techniques, the existence of positive solution and multiple solutions can be obtained. Moreover, we study the properties of decay estimates and asymptotic behavior for the positive solution.
Stacked machine learning models to classify atrial disorders based on clinical ECG features: a method to predict early atrial fibrillation
Authors: Budaraju Dhananjay , Neelapu Bala Chakravarthy , Pal Kunal , Jayaraman Sivaraman 
Published: March 2023

Abstract

Objectives
Atrial Tachycardia (AT) and Left Atrial Enlargement (LAE) are atrial diseases that are significant precursors to Atrial Fibrillation (AF). There are ML models for ECG classification; clinical features-based classification is required. The suggested work aims to create stacked ML models that categorize Sinus Rhythm (SR), Sinus Tachycardia (ST), AT, and LAE signals based on clinical parameters for AF prognosis.

Methods
The classification was based on thirteen clinical parameters, such as amplitude, time domain ECG aspects, and P-Wave Indices (PWI), such as the ratio of P-wave length and amplitude ((P (ms)/P (µV)), P-wave area (µV*ms), and P-wave terminal force (PTFV1(µV*ms). Apart from classifying the ECG signals, the stacked ML models prioritized the clinical features using a pie formula-based technique.

Results
The Stack 1 model achieves 99% accuracy, sensitivity, precision, and F1 score, while the Stack 2 model achieves 91%, 91%, 94%, and 92% for identifying SR, ST, LAE, and AT, respectively. Both stack models obtained a computational time of 0.06 seconds. PTFV1 (µV*ms), P (ms)/P (µV)), and P-wave area (µV*ms) were ranked as crucial clinical features.

Conclusion
Clinical feature-based stacking ML models may help doctors obtain insight into important clinical ECG aspects for early AF prediction.
A Comparison of Hazard Vulnerability Indexes for Washington State
Authors: Sheehan Tim , Min Esther , Hess Jeremy 
Published: March 2023

Abstract
Factors associated with structural racism, disenfranchisement, poverty, and other persistent sources of inequity are associated with vulnerability and exposure to environmental hazards. Social, demographic, and environmental factors associated with vulnerability to environmental hazards have been used by many researchers to produce indexes of hazard vulnerability. In preparation for a climate change health risk assessment for Washington state, we compared methods and results from six indexes designed to support environmental health risk assessment. Production of these indexes varies in the number of variables considered, calculation complexity, and exposure of local causal pathways. Results for these indexes are generally very similar, especially at the highest decile of vulnerability, the exception being the Environmental Health Disparities index, the only one to consider hazard exposure. Some indexes used methods that hide causal pathways. Those that exposed causal pathways limited model structure. Results indicate that simpler indexes may be more appropriate for use in decision support tools as they require less overhead for data updates and scenario analysis and that other methodologies may provide a more useful framework for index generation.
Anti-leakage method of network sensitive information data based on homomorphic encryption
Authors: Shi Junlong , Zhao Xiaofeng 
Published: March 2023

Abstract
With the development of artificial intelligence, people begin to pay attention to the protection of sensitive information and data. Therefore, a homomorphic encryption framework based on effective integer vector is proposed and applied to deep learning to protect the privacy of users in binary convolutional neural network model. The conclusion shows that the model can achieve high accuracy. The training is 93.75% in MNIST dataset and 89.24% in original dataset. Because of the confidentiality of data, the training accuracy of the training set is only 86.77%. After increasing the training period, the accuracy began to converge to about 300 cycles, and finally reached about 86.39%. In addition, after taking the absolute value of the elements in the encryption matrix, the training accuracy of the model is 88.79%, and the test accuracy is 85.12%. The improved model is also compared with the traditional model. This model can reduce the storage consumption in the model calculation process, effectively improve the calculation speed, and have little impact on the accuracy. Specifically, the speed of the improved model is 58 times that of the traditional CNN model, and the storage consumption is 1/32 of that of the traditional CNN model. Therefore, homomorphic encryption can be applied to information encryption under the background of big data, and the privacy of the neural network can be realized.
Internal curing of ultra-high-performance concrete: A comprehensive overview
Authors: Haruna Sani , Adamu Musa , Ibrahim Yasser E. , Aliyu Muhammad Magana , Haruna Sadi Ibrahim 
Published: March 2023

Abstract
This article presents an overview of the research on the effects of internal curing (IC) on ultra-high-performance concrete (UHPC). The process of adding a curing ingredient to the concrete mixture to serve as a water reservoir is known as internal curing. IC is a viable technique for supplying additional water for curing cement-based material with lower water-to-binder concrete. It is distinct from externally applied curing. The water meant for internal water curing is dispersed within the concrete after it hardened and facilitated the hydration process. It was used to minimize self-desiccation and shrinkage in UHPC. Based on the reviewed literature, an exchange between mechanical characteristics and autogenous shrinkage for concrete was observed for internally cured UHPC. Even though IC affects the mechanical characteristics, after 28 days, it was possible to achieve a compressive strength of over 150 MPa. Thermal curing was found to exhibit a remarkable effect on the development of UHPC strength. Experimental findings revealed that using pre-saturated aggregates for IC improves the tensile strength of UHPC. The scanning electron microscope images revealed that the bulk of the voids within the super-absorbent polymer cavities are filled with portlandite.

Published: March 2023

Abstract
In this study, the (Cu and Al2O3/water) hybrid nanofluid flow is carried out in a porous cavity. The thermophysical structures of solid materials are used from the available literature to improve the thermal performance of the base fluid. The mathematical model as a porous cavity is mainly used in the distillation process and is vital for the storage of thermal energy. The magnetic field is also employed perpendicular to the flow field and the impact of the magnetic parameter examined versus fluid motion. Similarity variables are used to transform governing equations as simplified partial differential equations. The model is solved using the control volume-based finite element method. Boussinesq–Darcy force is employed for the motion of the fluid flow, and the Koo–Kleinstreuer–Li model is used to assess the characteristics of the hybrid nanofluids. The roles of the Hartmann number, Rayleigh number, porosity factor in the porous medium, and drag fin improve traditional fluids’ thermal distribution presentation. Recent results predict that the two different kinds of nanoparticles speed up the heat transfer through the porous cavity. The percentage analysis shows that the hybrid nanofluids (Cu and Al2O3/water) are prominent in improving traditional fluids’ thermal distribution. Finally, the grid sensitivity test is also carried out for hybrid nanoparticles to demonstrate that the results are asymptotically coherent.

Published: March 2023

Abstract
The heat transfer process of the sweeping jet and film composite cooling (SJF) structure of the turbine blade leading edge is complex. The current work divides the overall cooling effectiveness of the SJF into the impingement heat transfer effectiveness, the convection heat transfer effectiveness inside the film holes, and the external film cooling effectiveness by the decoupled method. Various cooling effectiveness proportions and trends are compared when the blowing ratios are 1.05, 2.07, and 4.11. There is an average ratio of 64.33% for impingement heat transfer effectiveness and 38.02% for convection heat transfer effectiveness. The ratio of external film cooling effectiveness gradually changes from positive to negative with the increase of the blowing ratio. Therefore, the proportion of external film cooling effectiveness and impingement heat transfer effectiveness should be considered when applying SJF. The convection heat transfer effectiveness cannot be ignored, especially when the design scheme of the shower head is used.
Influences of Music Reading on Auditory Chord Discrimination: A Novel Test Bed for Nonconscious Processing of Irrelevant Prime Meaning
Authors: Augsten Marie-Luise , Eder Stephanie J. , Büsel Christian , Valuch Christian , Ansorge Ulrich 
Published: March 2023

Abstract
The question whether nonconscious processing could involve higher-level, semantic representations is of broad interest. Here, we demonstrate semantic processing of task-relevant and task-irrelevant features of nonconscious primes within a novel, empirical test bed. In two experiments, musicians were visually primed with musical note triads varying in mode (i.e., major vs minor) and position (i.e., the arrangement of notes within a triad). The task required to discriminate only the mode in the following auditory target chord. In two experimental blocks, primes were either consciously visible or masked, respectively. Response times for auditory discrimination of the modes (relevant dimension) of heard triads were measured. Crucially, the targets also varied with respect to mode and position, creating different grades of congruency with the visual primes. Based on the Theory of Event Coding, we expected and found interactions between relevant and irrelevant semantic characteristics of masked primes, illustrating that even irrelevant prime meaning was processed. Moreover, our results indicated that both task-relevant and task-irrelevant prime characteristics are processed in nonconscious conditions only, and that practice in ignoring uninformative conscious primes can be transferred to a subsequent block. In conclusion, this study demonstrates cross-modal, automatic semantic processing using a novel approach to study such effects.
