Abstract
This paper presents the uncertainty quantification (UQ) framework with a data-driven approach using experimental data in metal additive manufacturing (AM). This framework consists of four steps. First, the experimental data, including process parameters and signatures, are obtained by performing tests in various conditions. Next, the model is constructed by surrogate modeling and a machine learning algorithm using the obtained data. Then, the uncertainties in a quantity of interest (QoI), such as bead geometry, surface roughness, or mechanical properties, are quantified. Lastly, the UQ is verified and validated using the experimental data. The proposed framework is demonstrated with the data-driven UQ of the bead geometry in gas tungsten arc welding (GTAW)-based wire + arc additive manufacturing (WAAM). In this case study, the uncertainty sources are process parameters and signatures, and the QoI is bead geometry. The process parameters are wire feed rate (WFR), travel speed (TS), and current, while the process signatures are voltage-related features. The bead geometry includes the width and height of single-beads. The results of the case study revealed that (1) verifying and validating the data-driven UQ of bead geometry with the normal beads was conducted, and the predicted values were within the 99% confidence intervals, (2) the bead width was negatively correlated with TS, and (3) the bead height had a positive and negative correlation with WFR and TS, respectively.

Abstract
Background: Chronic Kidney Disease (CKD) has been identified as a major public health problem for the past few decades. The study aimed to determine the prevalence CKD.
Methods: A descriptive cross-sectional study was conducted using the multistage cluster sampling technique. Study participants were 767 adults of 30 to 70 years. The estimated glomerular filtration rate (eGFR) was estimated using the CKD EPI equation. eGFR values below 60 mL/min/1.73 m2 for more than three months or eGFR values >60 mL/min/1.73 m2 with evidence of renal damage persistent for more than three months was defined as CKD. Presence of proteinuria with urine protein creatinine >20mg/mmol was defined as the evidence for kidney damage. Median and mean eGFR of the sample was calculated. Prevalence of CKD, proteinuria and suspected CKDu were described with 95% confidence intervals (CI).
Results: Median eGFR of the males was 92.0 ml/min/1.73m² (IQR: 80.0-102.7) while mean eGFR of them was 91.01 ml/min/1.73m² (SD=16.4). Median eGFR of the females was 93.0 ml/min/1.73m² (IQR:82.0-104.0) while mean eGFR of them was 92.62 ml/min/1.73m²(SD=16.0).
The prevalence of confirmed severe proteinuria (>50mg/mmol) and moderate proteinuria (≥15mg /mmol creatinine to ≤50mg/mmol) was 3.2 % (95%CI;1.9%-4.4%), and 3.8% (95%CI;2.4%-5.1%) respectively.
The prevalence of confirmed CKD was 8.2% (95%CI;6.4%-10.4%). The prevalence of confirmed stage one or stage two CKD was 5.6% (95%CI;4.1%-7.1%) and stage >3 was 2.6% (95% CI=1.6%-4.0%). There was a statistically significant difference in the prevalence of CKD between people of 51 to 70 years and 30 to 50 years (p<0.001) of age. The prevalence of CKD was not associated with the sex (p=0.07), ethnicity (p=0.31), area of living (urban or rural) (p=0.52). The prevalence of CKD was 6.4% (95%CI;4.8%-8.4%) among the patients who had any co-morbidity and 1.8% (95%CI;1.0%-3.0%) among those who have no co-morbidity. The prevalence of suspected CKDu was 2.1% (95% CI: 1.2%-3.4%).
Conclusions: Higher prevalence of confirmed CKD patients was in either stage one or two, older age and who had any co-morbidity.

Abstract

The paper presents the measurement results for parameters of the electromagnetic response to deterministic acoustic excitation of magnetite ore samples and model samples of cement-sand and cement-glass mixtures with inclusions of ferrite magnet, magnetite ore, brass and duralumin, including that in the magnetic field. The possibility of testing the characteristics of magnetizable solid-state defects by electromagnetic signal parameters is shown. The dependences of the amplitude of electromagnetic responses to external pulsed acoustic excitation are given. The impact of changes in the direction of the constant magnetic field applied to the sample with a magnetite ore defect on parameters of electromagnetic responses is shown. It was revealed that changes in the strength of the external constant magnetic field under acoustic excitation significantly affect the amplitude of the electromagnetic signal of magnetite ore. The obtained patterns can be used for objective hardware determination of the content of magnetizable defects in the test dielectric structure, and the content of magnetite ore in rock cores.

Abstract
Background

Cod liver oil (CLO) is a nutritional supplement derived from liver of cod fish. It has high level of the omega-3 fatty acids, eicosapentaenoic acid, and docosahexaenoic acid, and very high levels of vitamins A, D, and E. Supplementing cod liver oil for infant and children is associated with many health benefits such as decreased risk of upper respiratory tract infection, better visual development, and decreases chance of developing Type 1 diabetes. The main aim of this review is to assess the impact of codliver oil consumption in children’s and infants.

Methods

We used databases PubMed/MEDLINE, CINHAL and Cochrane library and other sources like Goggle and Goggle scholar. All searches were limited to English language without restriction for publication year. All studies identified through different databases combined, exported and managed using Endnote X9.1 software. Information’s such as Authors, study location, publication year, study design, sample size, comparison group and reported outcomes was extracted.

Result

From the results of this review, we can conclude that Cod liver oil is very important for children in many aspects. It reduces the risk of type 1 diabetes, through the anti-inflammatory effects of long-chain omega 3 fatty acids. It also decreases in upper respiratory tract pediatric visits during the winter and early spring. It also supports normal brain development and functioning and vision during the prenatal period and throughout infancy and childhood. Consumption of codliver oil is also useful in reducing the symptoms of ADHD in children.

Conclusion

As a conclusion, Cod liver oil is very important to health of children since it contains omega-3 fatty acids and vitamins A, D, and E. Cod liver oil is important in reducing risk of type 1 diabetes, upper respiratory tract pediatric visit and ADHD. Cod liver oil is crucial for fetal brain development and enhancement of IQ score, and fetal visual development. More attention to this important nutrient by the concerned body may lead to improved dietary supplements and prevention of many diseases in children.

Abstract
Mitochondria are dynamic organelles and important for cell growth and proliferation. Dysregulated mitochondrial dynamics are highly associated with the initiation and progression of various cancers, including ovarian cancer. However, the regulatory mechanism underlying mitochondrial dynamics is still unclear and needs to be further studied. Previously, our study showed that Carnitine palmitoyltransferase 1A (CPT1A) is highly expressed in ovarian cancer cells and promotes the development of ovarian cancer. Here, we found that CPT1A regulates mitochondrial dynamics and promotes mitochondrial fission in ovarian cancer cells. Further study showed that CPT1A regulates mitochondrial fission and function through MFF to promote the growth and proliferation of ovarian cancer cells. Mechanistically, CPT1A promotes succinylation of MFF at lysine 302 (K302), which protects against Parkin-mediated ubiquitin-proteasomal degradation of MFF. Finally, the study showed that MFF was highly expressed in ovarian cancer cells and that high MFF expression is associated with poor prognosis in patients with ovarian cancer. MFF inhibition significantly inhibited the progression of ovarian cancer in vivo. Together, CPT1A regulates mitochondrial dynamics through MFF succinylation to promote the development of ovarian cancer. And MFF is a potential therapeutic target for ovarian cancer.

Abstract
In the developed field of information and communication systems, the utilization of wireless sensor networks (WSN) is greatly increasing. In WSN applications, data gathering with limited energy consumption and good security is essentially needed nowadays. The network is energy limited as the sensor nodes are operated using battery power. The nodes in WSN are vulnerable to several attacks and the proposed data transmission scheme should provide network security. The security is a main concern in data aggregation. In this work, a secured data aggregation scheme with compression technique and blockchain encryption added routing is presented. The existing methods on secured data aggregation give protection against attacks; still they suffer from issues such as energy, memory size and transmission costs. The devices in the network transmit data to the base station/server in the network through gateways. The data transmitted by the device is added with a hash key generated using spider web based dynamic key (SWDK) generation process. Then, compression based data aggregation is utilized to reduce the data size and sequentially the transmission cost. The security added compressed data is transmitted using block chain encryption routing. The simulation results prove that the proposed work gives reduced transmission cost and energy consumption comparing with the existing works. The network throughput increases due to the sharing security keys, as well as network latency and packet dropping are reduced in the proposed work.
Free-Floating Dynamic Material Removal Mechanism

Published: October 2022

Abstract
Honing is an abrasive-based superfinishing process to generate desired dimensional accuracy and functional surface texture. To predict dimensional accuracy of honed components, it is necessary to address and establish an accurate material removal model. However, honing operation differs from other abrasive-based material removal processes such as grinding and polishing in terms of its unique dynamic floating characteristic in the finishing of hole parts such as cylinder bore, adding complexity and difficulty when constructing material removal models. The existing material removal
models concerning honing tend to consider the effects of honing trajectory density, pressure, speed and oilstone properties, which are, in essence, the static analysis and ignores the free-floating of honing tools. Therefore, the paper proposed an original honing material removal model based on minimum energy principle to incorporate the effect of free-floating characteristic of honing tool inside hole parts into model. In minimizing constructed objective function 𝐹𝑜𝑏𝑗𝑒𝑐𝑡𝑖𝑣𝑒 from material removal matrixes of all oilstones distributing on honing head, the model identified the stable spatial position of honing head inside cylinder bore after free-floating, based on which, the material removal matrix corresponding to each oilstone can be identified. Thus, the oilstones’ material cutting processes are dynamically connected with each other, overcoming the static and independent analysis for existing researches. To validate the authenticity and credibility of proposed model, the single stage honing experiment was conducted, and the results showed that simulated inner wall profile after honing using proposed material removal model presented consistency with experimental results in terms of bore diameter enlarging effect and inner wall profile error reflection effect. Furthermore, the simulated results predicted leveling effect for inner wall profile to improve roundness and cylindricity error of cylinder bore, which is the fundamental mechanism of honing but not observed in experiments due to possible exterior errors introduced

Abstract
Background
Malaria in pregnancy is a major public health problem in developing countries, with a high impact on maternal and child morbidity and mortality. Intermittent Preventive Treatment with Sulfadoxine-Pyrimethamine during pregnancy (IPTp-SP) is one of the strategies recommended by the World Health Organization (WHO) to fight against this flail. However, data on its use in rural Burkina Faso are scarce. The aim of our study was to determine the coverage and factors associated with uptake of the optimal dose (2 doses) of IPTp-SP in the Rural Health District of Houndé before the adoption of the new WHO guidelines.
Methods
A cross-sectional study was conducted from 1 January 2006 to 31 December 2012 among 7188 pregnant women who showed up at least once for an antenatal consultation (ANC) in five rural primary healthcare centres in Health District of Houndé and for whom information on dispensation was available. Sociodemographic and IPTp-SP data were collected from ANC registries using a structured collection form. Factors influencing uptake of the optimal dose of IPTp-SP were explored using logistic regression.
Results
A total of 5103 pregnant women out of 7188 (70.99%) had met the optimal dose of IPTp-SP recommended by WHO. Half of them had performed at most 3 ANCs. The median age of the participants was 24 years (IQR: [20–28]). Having performed a least 4 ANCs was associated with compliance (adjusted odds ratio [95% CI] = 1.66 [1.48–1.88]), but also compliance with the optimal dose varied significantly between primary healthcare centres (p < 0.001)
Conclusion
We found that from 2006 to 2012, the uptake of optimal IPTp-SP doses was low in Houndé. The target of 80% coverage of the optimal dose of IPTg-SP was not achieved in rural areas before the new WHO guidelines were adopted. Strategies must be adopted to encourage women to perform ANC and to make sexual and reproductive health services more accessible.

Abstract
Organic amendments in aided phytostabilization of waste slag contain high levels of heavy metal (loid)s (HMs) is an important way to in situ control the release of HMs. However, the effects of dissolved organic matter (DOM) derived from organic amendments on HMs and microbial community dynamics in waste slag are still unclear. The results showed that the mercury (Hg)- thallium (Tl) mining waste slag without the addition of DOM continuously decreased pH and increased EC, Eh, SO42−, Hg, and Tl in the leachate with increasing incubation time. The addition of DOM significantly increased pH, EC, SO42−, and arsenic (As) but decreased Eh, Hg, and Tl. The addition of DOM significantly increased the diversity and richness of the bacterial community. The dominant bacterial phyla (Proteobacteria, Firmicutes, Acidobacteriota, Actinobacteriota, and Bacteroidota) and genera (Bacillus, Acinetobacter, Delftia, Sphingomonas, and Enterobacter) were changed in associated with increases in DOM content and incubation time. The DOM components in leachate were humic-like substances (C1 and C2), and the DOM content and maximum fluorescence intensity (FMax) values of components C1 and C2 in the leachate decreased and first increased and then decreased with increasing incubation time. The correlations between HMs and DOM and the bacterial community showed that the geochemical behaviours of HMs in Hg-Tl mining waste slag were directly influenced by DOM properties and indirectly influenced by DOM regulation of bacterial community changes. Overall, these results indicated that DOM properties associated with bacterial community changes increased As but decreased Hg and Tl mobilization from Hg-Tl mining waste slag.

Published: October 2022

Abstract
With the motive to reduce the high cost incurred in Wavelength division multiplexing (WDM) based free-space optics (FSO) communication system, Spectrum-sliced (SS) WDM based FSO communication system at a data rate of 2.5 Gbps per channel is proposed in this research article. Utilizing the broadening of the spectrum by means of supercontinuum generation in a highly non linear Fiber (HNLF), an economical SS-WDM based FSO system is designed. The narrow spectrum of laser light source is broadened by means of self phase modulation (SPM). The proposed work confirms that the DQPSK based SS-WDM FSO system has higher performance in terms of Q-factor and BER compared to other intensity modulation formats as well as differential phase modulation formats. Considering various values of FSO link distances, antenna diameters of transmitter and receiver, beam divergence and thus, determining the values of Q-factor and BER, Differential quadrature phase shift keying (DQPSK) based SS-WDM FSO system is simulated.

AbstractPurpose Patients who do not achieve pathological complete response (pCR) after neoadjuvant systemic treatment (NST) have a significantly worse prognosis. To date, the prognostic role in terms of disease-free survival (DFS) between the terminal index of Ki-67 after surgery (Ki-67T) and the combination of the baseline Ki-67 at biopsy before NST (Ki-67B) and the percentage change of Ki-67 before and after NST (Ki-67C) has not been compared. Methods We retrospectively reviewed 499 patients who were diagnosed with breast cancer from August 2013 to December 2020 and then received NST with anthracycline plus taxane. Results Among all patients, 335 patients did not achieve pCR. The median follow-up was 36 months. The optimal cut-off value of Ki-67Cto predict a DFS was 30%. A significantly worse DFS was observed in patients with low Ki-67C. The exploratory subgroup analysis also showed relatively good internal consistency. Clinical lymph node status, Ki-67C, and Ki-67Twere considered independent risk factors for DFS. Patients with a low Ki-67Brespond differently to chemotherapy, and those who are sensitive to chemotherapy have a relatively good prognosis. The forecasting model of combining Ki-67Band Ki-67Cshows a statistically significant higher area under the curve at year 3 and 5 than Ki-67T. Conclusion Ki-67Cand Ki-67Tare good predictors of DFS, while Ki-67Bis inferior. The DFS of patients with low Ki-67Bbut low Ki-67Cis not very satisfactory, and this patient population must not be neglected. Additionally, the combination of Ki-67Band Ki-67Cis superior to Ki-67Tin predicting DFS.

Published: October 2022

Abstract
This paper put forward an indirect method to measure the road irregularities of the monorail. Parallel computation, fused with the genetic algorithm, is used to calculate road irregularities and detect wheel failure. By intelligently modifying the vehicle parameters, the multi-rigid body model's simulation result could be close to the test data. This method overcomes the problem that the transfer function cannot be applied to the nonlinear system and the shortcoming of significant errors in the simplification process of the mathematical derivation method. Besides, it improves the traditional algorithm to shorten the calculation time and benefit big data processing. The application of the artificial intelligence method, which includes the intelligent detection of the wheel eccentricity, the brilliant weighing of human subjective judgment, the intelligent matching of the peak frequency signals of the simulation and test data, and so on, could be the highlights of this paper. The result shows the road irregularities calculated in this paper are in good agreement with that theoretical value.

Published: October 2022

Abstract

Background and Objectives
Very Low Birth Weight (VLBW) infants, born weighing less than 1500 grams, are at risk for both gut dysbiosis and later neuropsychological developmental deficits. With gut dysbiosis there is a disequilibrium of the gut microbial community. The Gammaproteobacteriadominated gut dysbiosis in VLBW infants likely results from a combination of immaturity derived from interrupted intrauterine development and environmental exposures in the Neonatal Intensive Care Unit (NICU) after birth. The extent of later neurobehavioral consequences associated with such microbial dysbiosis have yet to be determined.
Methods
We explored associations between the infants’ gut microbiome richness, diversity, composition, and network and early childhood behavior at 2 and 4 years of age in 25 children who were previously preterm born and studied while hospitalized in the Neonatal Intensive Care Unit (NICU). Behavior was measured with the Child Behavior Checklist (CBCL) at home visits at 32.2+/-4.8 months, and again at 49 +-3.6 months. We also measured children’s microbiomes at 2 and 4 years of age.
Results
The diversity and richness of the gut microbiome in VLBW infants were associated with later parent-reported maladaptive behavioral and emotional symptoms, including symptoms associated with autism, anxiety, Attention-Deficit/Hyperactivity Disorder (ADD), attention problems, and aggressive behavior. Microbiome compositional signatures were also associated with later childhood behavior. Network analysis revealed that the microbiome networks differed in the children at 2 and 4 years of age and different amplicon sequence variants (ASVs) were associated with behavior at these timepoints.
Conclusions
These data provide preliminary support for relationships between both the VLBW and later child gut microbiome dysbiosis and childhood behavior.
