Published: July 2023

Abstract
Ventilation door are commonly found in tunnels and other underground engineering ventilation structures, disaster periods using its explosion isolation, explosion relief, wind regulation characteristics for disaster prevention and mitigation is of great significance.This paper numerically simulates the propagation characteristics of the gas explosion shock wave in the nearby tunnel when the ventilation door are opened at different degrees, and analyzes the influence mechanism of the opening degree on the change law of the shock wave overpressure distribution in the nearby tunnel.The results show that the shock wave forms a strong turbulence area (high pressure area) on both sides in front of the ventilation door, and the area range and the overpressure value decrease with the increase of the opening degree; the ventilation door reduce the intensity of the shock wave, so that the overpressure behind the ventilation door decreases, and the smaller the opening degree, the lower the overpressure behind the ventilation door.The secondary explosion formed shock wave and the ventilation door reflected shock wave meet to form a stronger shock wave, which leads to different opening degrees of ventilation door, its before, after the roadway and after the bifurcation of the main roadway in the measured points of the overpressure change curve is different, the main difference is that the peak overpressure for the first wave or the second wave peak. The peak overpressure in the tunnel before and after the ventilation door decreases and increases respectively with the increase of the opening length, and the overall decay of the peak overpressure at 5m and 10m before the ventilation door is 49.56% and 4.04% respectively and only has an effect on the peak overpressure in main tunnel within 20m from the bifurcation.

Abstract

Background The response of venetoclax (VEN)-based therapy is closely associated with genetic patterns and combining regimens in acute myeloid leukemia (AML). Whether other agents added to VEN plus hypomethylating agents (HMA) regimen could overcome the negative impact of genetic patterns on response remains unclear.
Methods A multi-center, cohort study of the response and the genetic patterns of response of VEN plus AZA and HHT (VAH) versus VEN plus AZA (VA) regimens as salvage treatment in the patients with RR-AML was performed. Patients were enrolled from four studies from October 2018 to December 2022 at nine medical centers in china. The endpoints in this study were to evaluate the rate of composite complete remission (CRc), measurable residual disease (MRD), event-free survival (EFS), overall survival (OS) and relapse between VAH and VA groups.
Results A total of 321 patients were analyzed, including 150 females and 171 males, with a median age at 46 (IQR, 35–61) years. There were 172 patients in the VAH and 149 in the VA group. VAH significantly improved CRc rate (66.3% vs. 44.3%, P < 0.001) and prolonged OS (median OS, not reach vs. 14.3 months, P = 0.004), to compared with VA. VAH significantly overcame the negative impact of FLT3-ITD/TKD, N/KRAS, TET2, DNMT3A mutations, and t(8;21)/AML1-ETO, as well as non-adverse ELN risk, also apparently in adverse ELN risk or complex karyotype, on the response of VA regimen.
Conclusion The impact of genetic patterns on the response presented diversely in different VEN-based regimens. HHT added to VA regimen might improve the response and overcome the negative impact of part genetic patterns in RR-AML.

Abstract
Aim: To investigate the effects of a 10-day tapering on the metabolic and hematologic changes and a 200 m crawl swimming record.
Methods:Eighteen male recreational swimmers (11-17 years) underwent an eight-week vigorous-intensity endurance training (3 sessions per week, 90 minutes per session). Participants' swimming records were obtained at the end of the training period, and blood samples were drawn. After that, the taper group (TP) underwent a 10-day taper program (training volume reduced by 15%, 30%, 45%, and 60% in the first four sessions and 70% in the last session), while the control group (CG) kept their training load. At the end of the tapering period, 200 m crawl swimming time was recorded, and a blood sample was collected to assess metabolic and hematologic factors.
Results: 200 m swimming record was improved in the TP (149±17s) compared to the Co (173±21s) (p < 0.05). In addition, creatine phosphokinase, creatinine, urea, uric acid, and lactate dehydrogenase significantly decreased after tapering (p < 0.05). However, hematological factors did not show any significant changes between groups. Furthermore, no significant correlation between swimming records and measured parameters was found.
Conclusion: Our results showed that ten days of tapering could improve the 200 m swimming record and metabolic but not the hematological profile in young male recreational swimmers.

Authors: Zhang Zheng , Lu Jie , Ren Quan , Li Ziyong , Hu Yuxiang , Chen Hongchang 
Published: July 2023

Abstract
Super spread detection has been widely applied in network management, recommender systems and cyber space security, which is more complicated than heavy hitter, owing to the requirement of duplicate removal. Accurately detecting super spread in real-time with small memory remains a nontrivial yet challenging issue. The previous work either had low accuracy or incurred heavy memory overhead and could not provide precise cardinality estimation. This paper designs an invertible sketch for super spread detection with small memory and high accuracy. It introduces a power-weakening increment strategy that create an environment encouraging sufficient competition at the early stages of discriminating super spread and amplifying the comparative dominance to maintain accuracy. Extensive experiments have been performed based on actual Internet traffic traces and recommender system dataset. The trace-driven evaluation demonstrates that our sketch actualizes higher accuracy in super spread detection than state-of-the-art sketches. The super spread cardinality estimation error is 2.6-19.6 times lower than that of the previous algorithms.

Published: July 2023

Abstract

In order to achieve low refractive index detection in biomedical and material chemistry, a D-type microstructured optical fiber (MOF) sensor based on surface plasmon resonance (SPR) is proposed in this paper. The sensor uses gold nanofilm as sensing material between the core of the fiber and the plasma on the surface, and is coated at the open-ring. Parametric analysis of the open-ring diameter, air hole diameter and thickness of the gold nanofilm of the sensor was carried out by finite element method. The simulation results show that the sensor has a wavelength sensitivity of up to 10900 nm/RIU, the refractive index range of 1.20–1.34, optimal resolution of 9.17×10− 6 RIU, and a decent figure of merit (FOM) is 46.2 RIU− 1. The proposed MOF-SPR sensor has high wavelength sensitivity and low resolution in a similar detection range compared to existing studies. The sensor is capable of detecting not only low refractive index substances, such as liquid medical oxygen with a refractive index of 1.22 and sevoflurane with a refractive index of 1.27, but also conventional refractive index substances such as water contamination with a refractive index near 1.33, providing a wide detection range. Therefore, the sensor is competitive in the detection of some low refractive index material detection fields.

Abstract
In the era of artificial intelligence, automation is becoming popular in every sector. The primary sector includes the agriculture sector. Farmers are facing problems such as the identification of diseases in their plants, lack of proper treatment for the disease, climatic changes that affect their yield, and low price for their crops. In this paper, we are mainly focusing on the disease identification of bell pepper plants using deep learning architectures such as Alex Net, google net, ResNet (18,50,101), and Vgg (16,19). We also focus on the detailed study of different pre-trained CNN architectures to analyze their performance and identify which architecture is more suitable for disease classification in bell pepper. This paper also helps bell pepper farmers to identify the disease with high accuracy compared to the traditional methods of disease identification. The new automation concept helps bell pepper framers to identify diseases with less time and effort, which makes their work easier. The identification of disease at an early stage with less effort will help the farmer to increase their yield. The paper will help to understand the performance of different pre-trained convolutional neural network architectures with and without augmentation of images and also compare the performance of the architectures. Based on these comparisons, it could find out that google net is more suitable for the classification of images in bell pepper as compared to other architectures with augmentation, and vgg19 was observed to be best for the classification of images without augmentation.

Abstract

This research aims to synthesize silver-doped titanium dioxide (Ag-TiO2) nanoparticles using sol-gel and coprecipitation methods and evaluation the antibacterial behavior of TiO2 and Ag-TiO2 nanoparticles against Staphylococcus aureus (S. aureus), a Gram-positive bacteria, and Escherichia coli)E. Coli(, a predominant Gram-negative bacteria. Also, the optimal conditions were investigated based on the anatase phase of TiO2 due to its higher antibacterial activity than the rutile form. It was observed that temperature and pH have an important role in the phase change of TiO2 during the fabrication of nanoparticles. The Ag-TiO2 nanoparticles at different percentages of Ag 5, 10, 15, and 20% were used at two pH ranges of 4-4.5 and 8-8.5, and three temperatures of 450, 550, and 700°C. According to our findings, the temperature of 450°C and pH = 8-8.5 are suitable for forming the anatase phase, and the temperature of 700°C and PH = 4-4.5 are suitable for forming the rutile phase. It was observed that Ag-TiO2 with the percentages 15%-20% is doped with Ag and PH = 8-8.5, and a temperature of 450°C are favorable conditions for antibacterial activities. Identification of crystalline phases and the crystallite size estimation were investigated using the X-ray Diffraction (XRD) method. The XRD spectrum of TiO2 shows that the anatase phase is the most abundant at 450°C. Although at 550°C, anatase and rutile phases are present, it was confirmed that at 700°C and above, the rutile phase is the most abundant.. Antibacterial behavior of synthesized nanoparticles against Staphylococcus aureus and Escherichia coli (E. Coli) bacteria were evaluated by disk diffusion test method, and it was observed that the antibacterial activity of TiO2 improves by Ag doping.

SSDF attack detection algorithm based on fog computing in cognitive radio-based Internet of Things
Authors: Liu Miao , He Qing , Nie Zhongwen , Sun Zhenxing 
Published: July 2023

Abstract
In cognitive radio-based Internet of Things (CRIoT), security attacks of malicious devices disrupt the spectrum sensing process. The most common attack method, Spectrum Sensing Data Falsiﬁcation (SSDF) attack, attempts to make the Fusion Center (FC) misjudge the existence of the primary user (PU) by sending false energy sensing data. We propose an SSDF attack defense algorithm to deal with this security threat, which adopts fog computing architecture. FC performs Meanshift clustering, Clustering data ﬁltering, and data evaluation on the sensing data sent by CR-IoT devices to allocate appropriate weights, obtain more appropriate fusion energy and achieve the goal of accurately detecting the presence of PU. Simulation results show that in three different attack scenarios, compared with other algorithms, the proposed defence algorithm has a higher detection probability and can resist SSDF attacks more effectively.

Abstract
Purpose: Childhood cancer survivors (CCS) are at risk for increased morbidity and reduced quality of life associated with treatment-related late effects. In Germany, however, only a few of the more than 40,000 CCS registered in the German Childhood Cancer Registry (GCCR) currently benefit from adequate clinical long-term follow-up (LTFU) structures. To establish a comprehensive knowledge base on CCS’ long-term health in Germany, a database was developed in cooperation with the GCCR. Following a first evaluation phase at two German university centres, this database will be implemented more widely within Germany allowing longitudinal documentation of clinical LTFU data.
Methods: The feasibility study cohort comprised 208 CCS aged 18 or older whose medical, mental and psychosocial health data were collected during routine LTFU or first clinic visits in adult care. CCS were enrolled from 04/2021 to 12/2022, and data entry was completed by 03/2023. Descriptive data analysis was conducted. All CCS were stratified into three risk groups (RG) based on their individual risk for developing late effects resulting from their respective diagnoses and treatments.
Results: Chronic health conditions of various organ systems associated with late and long-term effects of cancer therapy affected CCS in all RG supporting the clinical relevance of risk-adapted LTFU. Enrolment into the database was feasible and broadly accepted among CCS.
Conclusion: Implementation of a clinical follow-up care infrastructure and database in Germany will pave the way to collect clinically evaluated and regularly updated health data of potentially over 40,000 German CCS and facilitate future national and international cooperation.

Abstract
Background
Family planning (FP) service integration into primary health care (PHC) is an effective approach to improve FP use, and maternal and child health outcomes. The Ethiopian government promotes integration of FP services into primary health care. However, there is paucity of evidence on the status of FP service integration. The aim of this study is to explore the state of FP integration into PHC services and identify facilitators and barriers to integration.
Methods
A qualitative study nested with a larger national study was conducted from July to October 2022. A total of 60 interviews were conducted with FP stakeholders including, government organizations, non-governmental organizations, donors, service providers, and clients. Interviews were audio recorded, transcribed, and coded using OpenCode 4.03. The coded data were analyzed using framework analysis approach, using the Primary Health Care Performance Initiative (PHCPI) framework. Direct quotes and results from the coding and categorization were used to develop the report.
Results
Family planning is largely provided in designated units by dedicated staff within PHC facilities. The provision of integrated FP service within each service unit is in its early stage. Successful examples of integration include integration of FP with postnatal care, abortion care, and youth-friendly service centers. Facilitators of integration include commitment of the government and partners, the presence of policies and guidelines, and positive attitude of service providers and clients. However, integration of FP also faces challenges that are largely related to challenges of the FP program even before integration. These include resource shortage, health workers shortage, health workers’ capacity/skill gaps, misconceptions about FP, religious and socio-cultural norms, and lack of awareness.
Conclusions
Integration of FP with PHC services in the Ethiopian public health facilities is viable. Pre-existing challenges of the FP program continued to be barriers to integration. Expanding the experiences of good practices in the integration of FP with post abortion care, post-natal care, and youth-friendly service centers to other components of PHC warrants attention. Addressing both supply- and demand-side challenges of the FP program is needed to facilitate the integration of FP with other PHC services.
Cobalt supported on silica-alumina nanocomposite for use in CO 2 methanation process: Effects of Si/Al molar ratio and Co loading on catalytic activity

Published: July 2023

Abstract
Metal-based nanocatalysts have emerged as important materials to turn carbon dioxide (CO2) into hydrocarbon fuels in order to deal with global climate issues and solve growing energy needs. Here, mesoporous silica-alumina (SA) nanocomposites are synthesized by a facile sol-gel method using citric acid monohydrate with different Si/Al molar ratios (X = 0.1–10), followed by impregnating cobalt on them. The resulting Co/SA-X catalysts are characterized by various techniques, and utilized in the production of substitute natural gas through CO2 methanation as a renewable energy storage system. The porous structure of the supports with suitable particle size distribution and superior reduction behavior provides the catalysts with high stability. The Si/Al molar ratio and Co loading are optimized at 0.5 and 15 wt%., respectively, achieving a high CO2 conversion of 78.5% and CH4 selectivity of 89%. Alternatively, different amounts of cobalt are loaded on the selected support (SA-0.5), while also investigating various parameters such as the feed ratio (H2/CO2 molar ratio), gas hourly space velocity, and catalyst stability. By increasing the feed ratio to 4, the CO2 conversion and CH4 selectivity are enhanced to 83% and 90%, respectively, indicating the excellent performance of the SA supported nanocatalysts to address both the environmental concerns and the needs for sustainable energy.

Abstract
In this paper, a novel microring resonator (MRR)-assisted Mach-Zehnderinterferometric (MZI) structure to operate as an electro-optic half adderutilizing the optical switching phenomenon of Si-MRR is proposed. Theproposed device has two Si-MRRs with dual inputs, used in the tandemconfiguration in the lower and upper arms of an MZI structure.An externally controllable optical ‘π’ phase shifter is also incorporatedin one of the arms of the MZI. The carrier-injected forward-biased PINwaveguide structure is incorporated into the ring resonator architectureto achieve the extinction ratio (ER) tunability. For the proposedelectro-optic adder, -1.85 V and +2 V are considered as logic 0 and1, respectively. One of the output terminals will emulate an opticalAND gate providing the carry bit (CB), while the other output terminalwill emulate an optical EX-OR gate offering the sum bit (SB).The proposed device was modeled and simulated using MATLAB. Thesimulation results estimate the simulated static ER of the SB andCB is 27.44 dB and 18.08 dB, respectively. To demonstrate the proposeddevice’s efficacy, two 10 Gb/s PRBS input streams at 1550 nm were used, and the time domain simulation results indicate a successfulelectro-optic half adder suitable for photonic integrated circuits (PICs).

Published: July 2023

Abstract
Let σq : Rq → Sq \ Nq be the inverse of the stereographic projection with centre the north pole Nq. Let Wi be a closed subset of Rqi , for i = 1; 2. Let Φ : W1 → W2 be a bi-Lipschitz homeomor-phism. The main result states that the homeomorphism σq2 οΦοσ-1q1 is a bi-Lipschitz homeomorphism, extending bi-Lipschitz-ly at Nq1 with value Nq2 whenever W1 is unbounded.
As two straightforward applications in the polynomially bounded o-minimal context over the real numbers, we obtain for free a version at infinity of: 1) Sampaio's tangent cone result; 2) Links preserving re-parametrization of definable bi-Lipschitz homeomorphisms of Valette.
