Abstract
Big data demands the cloud for storage, but organizations are not relying on the cloud, because of security and privacy reasons. When choosing the cloud for data storage, users worry about issues such as leakage of personal information, unauthorized user access and modification of data, and malicious behavior in cloud data access. Privacy leaks should be avoided during data analysis. Data integrity must be maintained to avoid data modification. Also need machine learning models to detect malicious activity patterns from users in the cloud to ensure data security. Therefore, big data requires technology that protects privacy and security with minimal investment of time and space. Hence approaches using anonymization, sanitization, integrity, and machine learning techniques are proposed. Anonymization can protect personal data from being disclosed upon receiving the data. The use of map-reduce along with anonymization reduces the computational overhead. Sanitization of type encryption/decryption with weighted fuzzy c-means clustering(WFCM) can protect privacy and security with less computation time. Elliptic curve with Diffie–Hellman (ECDH) algorithm is used to protect the integrity of the data with better accuracy than the other cryptosystem algorithms. To protect and safeguard the transactions in cloud applications, a novel solution using Machine Learning (ML) approach with Convolution Neural Networks and a support vector machine is employed. The efficiency of the classifier ability is measured using parameters such as precision, recall, and F-score. Therefore, all these techniques allow this research to protect the privacy and security of big data.

Published: November 2022

Abstract
Background
Experimental studies suggested that intercellular adhesion molecule 4 (ICAM-4) might be implicated in ischemic stroke, but the population-based evidence on the relationship between ICAM-4 and ischemic stroke were limited. Herein, we performed a two-sample Mendelian randomization (MR) analysis to investigate the associations of genetically determined plasma ICAM-4 with risks of ischemic stroke and its subtypes.
Methods
A total of 11 single-nucleotide polymorphisms associated with ICAM-4 were selected as instrumental variables based on the genome-wide association studies (GWAS) with 3,301 European individuals. Summary-level data about ischemic stroke and its subtypes were obtained from the Multi-ancestry GWAS launched by the International Stroke Genetics Consortium. We used the inverse-variance weighted method followed by a series of sensitivity analyses to evaluate the associations of genetically determined ICAM-4 with risks of ischemic stroke and its subtypes.
Results
Genetically determined higher ICAM-4 levels were significantly associated with increased risks of ischemic stroke (odds ratio [OR] per standard deviation [SD] increase, 1.04; 95% confidence interval [CI], 1.01–1.07; P = 0.003) and cardioembolic stroke (OR per SD increase, 1.08; 95% CI, 1.03–1.13; P = 0.003). There was no association of ICAM-4 with risks of large artery stroke and small vessel stroke. MR-Egger regression showed no directional pleiotropy for all associations, and the sensitivity analyses with different MR methods further confirmed these findings.
Conclusions
We found positive associations of genetically determined plasma ICAM-4 with the risk of ischemic stroke and cardioembolic stroke. Future studies are needed to explore the detailed mechanism and investigate the targeting effects of ICAM-4 on ischemic stroke.

Abstract

The study was conducted in Wonjeta St Micheal Church Forest, Northwestern Ethiopia. Fifty plots of 20m x 20m (400m2) were laid along five-line transect for vegetation data collection. In addition, 5m x 5m subplots were laid within the main plot to sample seedlings and saplings. All plots were laid at a distance of 50m along the transect lines. The diversity and population structure of woody individuals of trees and shrubs with a diameter at breast height (DBH) ≥ 2.5cm and height ≥ 2m were measured and DBH < 2.5cm and height < 2m were counted as seedlings and saplings. All trees and shrubs recorded in the 50 plots were used for vegetation structure analysis. A total of 65 woody plant species in 53 genera and 33 families were recorded. Out of the total number of species three were found to be endemic to Ethiopia.The family Fabaceae had the highest number of species, followed by Moraceae, and then Euphorbiaceae with 14, 6, and 4 species respectively.The results of Shannon Wiener diversity and evenness indices of woody species were 2.8 and 0.68 respectively. Woody species densities for mature individuals were 2,202.5 stems ha− 1, seedling 2419.2 stems ha− 1, and sapling 1737.6 stems ha− 1. Priority for conservation should be given using population structure, important value index, and regeneration status as criteria. Results of the structural analysis revealed that the Forest is highly dominated by small-sized trees and shrubs indicating that it is in the stage of secondary development and there are species that require urgent conservation measures.

Published: November 2022

Abstract
Textile wastewater has the potential to contain high ammonia, especially from the printing process. Nitrification-denitrification becomes the focus of treatment for this pollutant so comes the main source of the inability of the WWTP to meet the quality standards. An electrocatalytic reactor consisting of a cylindrical Ti/RuO2 anode and a copper pipe cathode (Cu) has been applied as new alternative technology. The reactor capacity is made of 1 liter with a fixed distance between the electrodes of 2 cm. Potential voltage, salt content, and hydraulic retention time are parameters for variable operation. The reactor had a high performance where ammonia concentration can be reduced by 70% for HRT of 15 minutes and 100% for 30 minutes. The ammonia removal is not only affected by processing time but also by the potential electrode and salt concentration. The removal was obtained at a complete level (100%) in operating conditions where the salt content of 2000 mg/L, a voltage of 7 volts, and an HRT of 30 minutes. The ammonia removal rate follows reaction order 1 with k of 0.1679 dan R2 of 0.9369. The pathway of nitrogen transforming ammonia directly to gas nitrogen was not through other forms (nitrate or nitrite). This method is a high-promise to improve the performance of the textile industry WWTP.

Published: November 2022

Abstract
Scratches are a continuous structural injury in old movies. Scratch pixel level segmentation algorithm still uses the general image segmentation algorithm, and the detection results are poor. According to the characteristics of scratches, a scratch model based on the Gaussian probability density function is proposed, a local adaptive one-dimensional Gaussian weighted segmentation algorithm is designed, and an invalid region filtering mechanism is introduced. Compared with several groups of experimental results, the local one-dimensional Gaussian weighted segmentation algorithm proposed in this paper can well preserve the integrity and continuity of scratches, and effectively suppress edge information, and the invalid region filtering mechanism can effectively reduce the false detection of scratches. Adding scratch trajectory can effectively reduce the missed detection rate of scratches, and the stability of the traditional algorithm using Kalman to predict scratch trajectory is poor. According to the similarity of multiple scratch trajectories, a calculation method of scratch trajectories based on U-net is designed. Experimental results show that this method can calculate scratch trajectory stably and effectively.

Abstract
The highly toxic heavy metal cadmium (Cd) can enter the body through biological enrichment. As an essential metabolic organ in the body, the liver is an important target organ of Cd poisoning. Quercetin (Que) is a type of flavonoid that exhibits the pharmacological activities of scavenging free radicals and antioxidation. 4-Phenylbutyrate (4-PBA) can alleviate endoplasmic reticulum stress (ERS) and is frequently considered an inhibitor of ERS. Previous studies have shown that Que can alleviate rat hepatocyte apoptosis caused by Cd; however, the mechanism remains unclear. To explore the specific mechanism of Que that alleviates Cd-induced hepatocyte apoptosis, we established a model of Cd toxicity and Que rescue in BRL-3A cells and used 4-PBA, an ERS inhibitor, as positive control. Cell Counting Kit-8 was employed to measure cell viability. Fluorescence staining was applied to observe cell apoptosis. Flow cytometry was performed to detect reactive oxygen species levels. Real-time quantitative polymerase chain reaction was adopted to detect the messenger RNA expression levels of ERS and apoptosis-related genes. Western blot was used to observe the expression levels of ERS/apoptosis-related proteins. We confirmed that Que could alleviate the apoptosis caused by Cd in BRL-3A cells by inhibiting the PERK/IRE1α/ATF6 ERS signaling pathway. The effects of Que were similar to those of ERS inhibitors.

Published: November 2022

Abstract

This study presents a linear approach that defines the water retention on organic substrates, namely composts and coir. Different substrates are used as sampling material for the experimental data. Results of this experiment show that based on recurring decimal logarithms, from analytical exponential expressions, using only two water retention experimental points, it is possible to define a linear water retention relation for a substrate between − 0.1 kPa and − 10 kPa matric potential values. Due to the low number of parameters involved in this empirical approach a more rapid and accurate determination of substrate water retention. Results indicate that there is a high agreement between the experimental and the prediction values (R2 = 0.953). Moreover, the precision and the simplicity of this method applied to several different organic substrates can contribute to its generalization. Due to its simplicity, it can be easily applied to a high number of cases. As an example, a well-known important application of this approach is on the application of tensiometers.

Abstract
This study aims at the valorization of Taxus baccata (L.) in corrosion inhibition. The effect of the extract on corrosion inhibition of mild steel in 1.0 M HCl solution by weight loss measurements, potentiodynamic polarization (PP) and electrochemical impedance spectroscopy (EIS) showed that Taxus baccata (L.) leaves extract is a good corrosion inhibitor with an inhibition efficiency of 98%, 96% and 95% at the concentration of 1.0 g/L respectively. Polarisation curves indicated that the extract acted as a mixed type inhibitor. The adsorption on the mild steel surface obeyed the Langmuir isotherm. The activation energy values ∆G0ads (-29.61 KJ.mol-1) confirmed the physical adsorption process of this inhibitor. The study of adsorption kinetics showed a maximum inhibitory efficiency of 90.5 % after one hour of immersion time. Scanning electron microscopy revealed the formation of a protective layer on the steel surface. Analysis of the extract by gas chromatography revealed the dominance of Diisooctyl phthalate (17.22%), Bicyclo [4.4.0] dec-2-ene-4-ol,2-methyl-9-(prop-1-en-3-ol-2-yl) (16.43%), Methanesulfonic acid,4-oxoadamantan-2-yl ester (8.75%), Diethyl phthalate (8. 31 %), The structural and electronic properties of the main components of this extract were calculated using DFT to better understand the adsorption behaviour and inhibition mechanism of this plant.
Rapid triple-frequency undifferenced integer ambiguity resolution with multi-GNSS: GPS, Galileo, GLONASS, BeiDou-3

Published: November 2022

Abstract
Currently, there are four dominant GNSS systems, i.e., GPS (G), Galileo (E), GLONASS (R), and BDS-3 (C), capable of providing multi-frequency positioning services worldwide. To fully take advantage of the multi-system multi-frequency signals on precise point positioning (PPP) for global clients, we resolved the triple-frequency PPP ambiguity resolution (PPP-AR) for the first time with the integration of GPS, Galileo, GLONASS, and BDS-3 triple-frequency observations. Especially, some new signals, e.g., GLONASS code-division multiple-access (CDMA) L3 and BDS-3 B2a observations, are integrated carefully into our proposed GERC triple-frequency PPP-AR model. Besides, to overcome the problem of GLONASS inter-frequency biases (IFBs) from the frequency-division multiple-access (FDMA) strategy, the uncalibrated phase delay (UPD) determination method based on the homogeneous receivers is presented. Then we comprehensively addressed the processing of multi-system inter-frequency clock biases (IFCBs) determination and calibration in the context of GERC triple-frequency PPP-AR. Datasets from twenty tracking stations of the regional EUREF Permanent Network (EPN) equipped with identical JAVAD receivers are utilized to validate our developed GERC multi-frequency UPD determination and PPP-AR. The quality of UPD estimates in terms of the residual distribution was studied first. Generally, the higher the accuracy of the UPD corrections, the smaller the residuals achieved. Results demonstrate that almost 100% of extra-wide lane (EWL) ambiguity residuals of each GNSS constellation were within 0.15 cycles. Moreover, the percentages of wide lane (WL) and narrow lane (NL) ambiguity residuals smaller than 0.25 cycles were also larger than 95%. Therefore, based on the precise UPD products, high-accuracy PPP-AR can be performed. Our results show that integrating the additional third frequency and multi-GNSS does contribute to improving the PPP-AR performance. The best convergence performance of about 0.71 min was achieved by the GERC triple-frequency PPP-AR, which is much shorter than that of G (7.32 min), GR (4.95 min), GC (3.10) and GE (1.39 min). Compared with the GERC dual-frequency PPP-AR (1.82 min), the triple-frequency solution also realized an improvement of about 61%. This result is encouraging because it demonstrates that the positioning errors of multi-GNSS PPP-AR can be rapidly converged within 1 min. We further investigated the PPP-AR performance with different session lengths of several solutions. When the session length reaches 10 min, the GERC triple-frequency PPP-AR solution realizes positioning errors of [0.28 0.36 0.98] cm, while that of GPS-only is [1.34, 0.73, 2.26] cm in the east, north and up directions.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic, but a progressive disease of the lung. The method of constructing an animal model is the groundwork for this consecutive research. How to build a typical human mimicking animal model remains challenging. Thus, to reveal the mechanism and to make it useful for IPF clinical treatment, this study aimed to use a different type of IPF mice model and use several inspection methods to evaluate which one is more applicable for the study of IPF. Twelve-week-old C57BL/6 mice were divided into 3 type groups, as intraperitoneal injection, intratracheal administration, and intravenous administration of bleomycin (BLM) to initiate lung fibrosis. Lung PET/CT of BLM-receiving mice showed an increase in fibrotic consolidations compared with that of saline control mice. CT quantification showed an increase in mean lung density in BLM-treated mice compare with that of saline controls. TGF-1, TNF-, IL-6, GM-CSF in BALF(Bronchoalveolar Lavage Fluid) and serum.PAI-1, HYP in the lung tissue of mice were significantly different in each BLM groups than those in the saline control group. The results of Masson staining in mice indicate that the lung tissues of the tracheal perfusion group, the intravenous injection group, and the intraperitoneal injection group have a higher degree of pulmonary septal thickening and collagen fiber consolidation. The intratracheal group is more advanced than the other groups. Picro-Sirius red staining results are consistent with the results of Masson staining. Compared with the saline control group, the ratio of Col 1/Col 3 was significantly increased in each BLM group. TEM results found that in BLM group, type I alveolar epithelial cells were degenerated and disintegrated, exfoliated endothelial cells were swelling, type II alveolar epithelial cells were proliferated, abundant microvilli were on the free surface of the cell, vacuolar degenerated in the intracellular lamellar bodies, the shape of the nucleus was irregular, and some tooth-like protrusions were seen. Based on the comparison of three different methods of animal model construction, high dose of each shows more compliable, and BLM can successfully induce animal models of pulmonary fibrosis, however, there are certain differences in the fibrosis formation sites of them three, and tail vein injection of BLM induced pulmonary fibrosis model is closer to the idiopathic pulmonary interstitial fibrosis.

Published: November 2022

Abstract
Plastic pollution need to be resolved as it affects air, water, land. The favourable alternative for plastics would be Polyhydroxybutyrate (PHB) from bacterial origin, which are biodegradable and biocompatible biopolymers. Focus on the PHB producing bacteria is done by collecting garden soil sample. Five colonies of Sudan black blue positive isolates were chosen, extracted, and produced. One of the strains (SM1) - a potent producer as confirmed by crotonic acid assay, was further subjected to large scale production. The PHB thus produced was analysed using Fourier Transform Infra-Red spectroscopy (FTIR) and Gas Chromatography Mass Spectrometry (GCMS) to confirm the presence of functional groups. X-Ray crystallography revealed that it is of crystalline nature and are pictured by Scanning electron microscopy photography. DNA was isolated from the strain SM1, and the gene for 16S rRNA has been sequenced and submitted in GENBANK, (Accession No: MZ363886). The organism was found to be Bacillus cereus as predicted by 16S rRNA and NCBI BLAST. A phylogenetic tree was constructed using MEGA software. Bioplastic preparation was done under laboratory scale and the produced bioplastic was successfully degraded using Pseudomonas species. The prepared bioplastic from bacteria was biodegradable and eco-friendly.

Published: November 2022

Abstract
Aiming at the problem of slow retrieval speed due to a large amount of data in person re-identification, this paper introduces Taylor expansion into a deep neural network, and obtains Taylor deep neural network for feature extraction, which is combined with the proposed hash probability coding algorithm, and get a fast retrieval algorithm for person re-identification based on the hash. The algorithm can not only extract the feature map information well but also perform image retrieval at a faster speed, which is a new method to solve the fast image retrieval of person re-identification. First, a Taylor deep neural network framework is proposed, and the feature representation extracted by each layer of the deep network is fused by Taylor expansion weighting to retain the overall features of the image and make the feature representation more comprehensive ; then, the triplet loss function Triplet Loss is optimized to improve the When the distance between groups cannot be optimized, the group loss function Group Loss is proposed. Finally, a new hash probability compression coding method is used to make the image retrieval fast. Experiments show that the algorithm model in this paper is 26.7% and 8.18% higher than the BaseLine model on the large data sets Cuhk03 and Market1501, respectively. It also has a good retrieval speed on images retrieved by person re-identification..

Published: November 2022

Abstract
Purpose: To describe the prevalence of visceral localizations, risk factors and overall mortality at 3 months in catheter-associated fungemia in ICUs and non-ICUs
Method: Retrospective study of patients with a fungal organism isolated on catheter blood culture. Clinical characteristics, visceral localizations, management and outcome were examined.
Results: One hundred forty five patients presented primary or secondary fungemia (median age 61 years, 57% males). Sixty visceral localizations occurred in 50 patients (34.5%) including digestive (n= 21), pulmonary (n=11), vascular (n=6), spleen (n=4); muscle (n=3); cerebral (n=2); liver (n=2); ocular (n=2), hip prosthetic joint infection (n=1), spondylodiscitis (n=1) and abdominal wall (n=1). There was no statistical association between visceral localizations and fungal agent (p=0.208) or type of catheters (p=0.225). Fifty-two patients (36%) died during follow-up. Overall mortality was associated with retention of the central line catheter (p<0.01), type of catheter (p=0.004), Charlson Comorbidity Index (p< 0.01), inadequate or absence of antifungal therapy (p<0.01), hospitalization in an intensive care unit (p<0.01) and renal failure (p=0.02).
Conclusion: Visceral localizations are common and not significantly associated with mortality in catheter-associated fungemia. Visceral localizations were not associated with the type of fungal agent and the type of catheter. Overall mortality is important and associated with important predisposing host conditions, the retention of the central line catheter and the type of catheter.
