Authors: Iyida Evaristus Uzochukwu , Onah Costecia , Eya Innocent , Odo Finbarr 
Published: April 2023

Abstract
The orientation and evolution based on unified scheme for jetted extragalactic radio sources posits that BL Lacertae objects (BLs), flat-spectrum radio quasars (FSRQs) and normal radio galaxies (RGs) represent increasingly misaligned populations of active galactic nuclei (AGNs). Using compiled radio, X-ray and γ-ray data of 397 blazars and 110 RGs from the Fermi Large Area Telescope (Fermi-LAT) catalogue, we computed the viewing angles, γ-ray core-dominance parameter and γ-ray emission components in order to study the consequences of orientation and relativistic beaming effects on γ-ray properties of RGs, BLs and FSRQs. Our results show continuous distributions of core-dominance parameters (X-ray, RX and γ-ray, Rγ) from RGs at low values, largest viewing angles to FSRQs at high values and BLs subsets with the least values. The difference on the plane is significantly larger for FSRQs and BLs than for RGs, indicating an evolutionary link between them. A two-sample Wilcoxon rank-sum and Kolmogorov-Smirnov tests carried out on our data suggest that the probabilities of the distribution of RX and Rγ of RGs and blazar types to come from the same parent distribution are pWRS ∼ 0 and pK−S < 10-5, suggestive of stronger beaming effects in blazars than in RGs. There is a significant correlation (r > 0.60) between log Rr - log RX for the combined sample types. Furthermore, a significant anti-correlation (r ∼ -0.80) exists in the log Rγ - log Lγ,un plot which is indicative of evolutionary sequence via relativistic beaming model. These results imply that the evolutionary track of jetted AGNs is RGs - BLs FSRQs
Improving Chest X-ray Report Generation by Leveraging Text of Similar Images
Authors: Niksaz Saeed , Ghasemian Fahimeh 
Published: April 2023

Abstract
Automatic medical report generation is the production of reports from radiology images that are grammatically correct and coherent. Encoder-decoder is the most common architecture for report generation, which has not achieved to a satisfactory performance because of the complexity of this task. This paper presents an approach to improve the performance of report generation that can be easily added to any encoder-decoder architecture. In this approach, in addition to the features extracted from the image, the text related to the most similar image in the training data set is also provided as the input to the decoder. So, the decoder acquires additional knowledge for text production which helps to improve the performance and produce better reports. To demonstrate the efficiency of the proposed method, this technique was added to several different models for producing text from chest images. The results of evaluation demonstrated that the performance of all models improved. Also, different approaches for word embedding, including BioBert, and GloVe, were evaluated. Our result showed that BioBert, which is a language model based on the transformer, is a better approach for this task.

Published: April 2023

Abstract
PURPOSE
Mandibular sagittal osteotomy is a recognized technique in orthognathic surgery, undergoing modifications over time in its original design aiming at trans and postoperative improvement. The lingual short split mandibular osteotomy technique presents a modification in the lingual design being shorter and below the lingula and is described with fewer complications. For years, radiographs were the only way to evaluate the design of osteotomies in these surgeries and the lingual trace could not be evaluated. Computerized tomography scans allowed the evaluation of the designs of the surgical fractures, making it possible to assess the postoperative result.
METHODS
This study prospectively analyzed 60 CT scans of patients operated on using the lingual short split technique, verifying the direction and path of the lingual cut.
RESULTS
As a result, 73.33% were type 1, 18.33% type 2, 6.66% type 3, and 1.66% type 4. Types 1 and 2 have a fracture line drawing similar to the original technique; type 3 has small variation; type 4 presented bone fragmentation.
CONCLUSION
We conclude that the technique is predictable, without significant statistical variables, and well-visualized tracing with the methodology used. A new classification of the technique was recommended and is necessary to correlate it with clinical results in future studies.

Published: April 2023

Abstract
Microalgae are considered as a promising industrial source for the sustainable production of valuable compounds, such as high-quality protein, polyunsaturated fatty acids, dietary fibre, pigments, minerals, and vitamins useful in different industries (i.e., nutraceutical, food, animal feed and cosmetics). Cell-wall disruption plays a key role in the recovery of these valuable compounds, so it is necessary to develop specific disruptive processes for each species of microalgae that achieve a more efficient recovery of these compounds. The present work aims to evaluate the combination of different extractive methods on Chlorella vulgaris concentrated liquid biomass in order to enhance and optimise protein solubilisation. Several cell disruption approaches, including mechanical (microwave assisted extraction, MAE) and non-mechanical treatments (enzymatic assisted extraction, EAE) have been investigated. Commercial enzymes including cellulase and a blend of carbohydrases have been applied as algal cells are strong and stable due to the presence of polysaccharides such as cellulose and hemicellulose. Optimisation of independent variables, such as pH (7.3, 9) and extraction time (1–10 min) was performed by Response Surface Methodology conducted through Design Expert software. The cell wall disruption was evaluated by analysis of protein solubilization (Kjeldahl method). It was found that all independent variables had a significant and favourable influence on protein solubilisation. MAE without an EAE pre-treatment step yielded a protein solubilisation about 21–67% dw, whereas adding an enzymatic pre-treatment step using Celluclast® and Viscozyme® yielded a protein solubilisation of 22–68% dw and 43–70% dw, respectively.

Authors: Tiwari Chandra Shekhar , Jha Vijay Kumar 
Published: April 2023

Abstract
The cloud platform is the best choice to provide more space for storing and transmitting data from one location to another in a fast manner for internet users. Nevertheless, while using cloud storage, several risks like data leakage and external attacks arise, especially owing to unauthorized users. Thus, to tackle these problems, this paper proposes Cued Click Points (CCPs) of the fused image with Galois KullbackLeibler Divergence-Elliptic Curve Cryptography(GKLD-ECC) and Log Left Shift-Hash of Variable Length(LLS-HAVAL) for secure data uploading along with retrieval in the cloud. Firstly, the users register their details in the database with the multiple CCPs on the fused image. During registration, the user should login with the provided details for uploading or retrieving data. Next, by employing GKLD-ECC in the cloud, Data Owners (DOs) securely upload data. Afterward, hashed access policy with LSS-HAVAL hash is created based on the features and attributes selected by the Interpolated-Sun Flower Optimization Algorithm (I-SFOA) to enhance the authorization process; also, the hashcode is shared with selected data users. The data can be retrieved successfully if the hashcode gets matched during retrieval. The performance of the proposed framework is verified by achieving a higher security level and lesser time.

Published: April 2023

Abstract
In the current study, the carbon quantum dots (CDs) were synthesized through a facile, rapid, and one-step microwave method using citric acid monohydrate and urea. The as-prepared CDs were spherical with diameters of 3–4 nm and displayed bright blue fluorescent under an excitation wavelength of 360 nm. Also, the as-prepared CDs had various properties, including favorable solubility in water, different functional groups, significant stability in various environmental conditions, and excellent optical performance. The results indicated that the CDs could be applied as a fluorescent probe for reliable and accurate detection of Diclofenac sodium (DFS) based on the enhancement of their native fluorescent intensity (turn-on). The emission spectra of the as-prepared CDs were strengthened gradually when the DFS concentration increased from 5 to 300 µM. In addition, the linear relationship was fabricated over the concentrations range of 5-300 µM for DFS with the detection limit of 2.33 µM. Furthermore, the findings showed that Fe doped CDs (Fe-CDs) like CDs have a good ability to detect various concentrations of DFS in the wide range of 5-300 µM.

Published: April 2023

Abstract
Introduction
Common Perinatal Mental Disorders affect women and children across the world. Rates are high in sub-Saharan Africa, however studies on interventions are limited. Highlighting existing and upcoming practice to support maternal mental health services is imperative.
Method
We conducted a systematic review, yielding a large array of papers covering 32 low- and lower-middle income countries across sub-Saharan Africa. No time limit was placed on publication and study protocols and results papers were included.
Results
Twelve articles from 8 different countries were included in our review; Gambia, Ghana, Kenya, Malawi, Nigeria, Tanzania, Uganda and Zimbabwe. Most interventions took a psychotherapeutic approach, two included a pharmaceutical component. Half the studies detailed adapted approaches to ensure cultural acceptance. Effectiveness was limited; 3 studies showed a significant impact, only one of which had a large effect size.
Conclusion
Evidence remains limited and efforts should be made to support the implementation and generation of evidence in a wide variety of countries and contexts. Task-shifting was a common approach, though services were delivered at health facility level rather than in communities. Scaling-up effective holistic approaches to maternal mental health and child wellbeing remains an area of need.

Authors: Peng Lingzhi , Xu Yan , Zhu Chenglou , Liu Tianxiang , Da Mingxu 
Published: April 2023

Abstract
Objectives: The aim of this study was to analyze the incidence, clinical features, treatment factors, prevalence, and prognosis of patients with multiple primary malignant tumors (MPMTs) in the gastrointestinal tract. Additionally, we aimed to analyze the different tumor combinations, the time interval between the occurrence of tumors, and staging.
Methods: This retrospective cohort study analyzed 8059 patients for pathologically confirmed gastrointestinal malignant tumors at the Gansu Province Hospital in Lanzhou, Gansu, China between June 2011 and June 2020. Of these, 85 patients had MPMTs. Their data were analyzed for clinical features, treatment factors, prevalence, and prognosis.
Results: The incidence of MPMTs was 1.05% (85/8059) in patients with gastrointestinal malignant tumors; that of synchronous multiple primary malignant tumors (SMPMTs) was 28 (32.94%); and that of metachronous multiple primary malignant tumors (MMPMTs) was 57 (67.06%), including 83 double primary malignant tumors and two triple primary malignant tumors. The most frequent associations were between the rectum colon cancers within the SMPMT category and the gastric-colon cancers within the MMPMT category. For the MMPMTs, the median interval was 53 months. The overall 1-, 3- and 5-year survival rates from diagnosis of the first primary cancer were 91.36%, 65.41%, and 45.97%, respectively; from diagnosis of the second primary cancer, they were 67.90%, 29.90%, and 17.37%, respectively.
Conclusions: Our results suggest that MPMTs in the gastrointestinal tract have a high incidence and poor prognosis. Thus, it is necessary to perform both gastroscopy and colonoscopy in patients with gastrointestinal tumors. Multidisciplinary comprehensive diagnosis and treatment may improve the diagnosis rate and treatment efficiency of MPMTs.
Effectiveness of Phthorimaea Operculella (Zeller) (Lepidoptera: Gelechidae) Potato Tuber Moth -Traps of Different Colors Baited with Pheromone in Summer Plantation
Authors: Gharib Mohamed Refaat 
Published: April 2023

Abstract
Background
In agricultural regions, traps can be used to track target pests using particular pheromones.
Result
Evaluation of the effects of trap color, trap direction, and trap location on Phthorimaea operculella (Zeller) captures of the potato moth. A pheromone capsule served as bait for each trap. More insects were captured by white pheromone traps than by yellow, blue, green, or red traps. The mean catches of the white and other coloured traps were found to vary significantly. Although there are negligible differences between the mean catches at each direction, the trap caught more moths when it was placed in the south or centre of the infested region than when it was placed in the west, east, or north. When compared to the two other locations (50 and 100 cm above the ground), the collective capture of P. Operculella moths made by the ground-resting traps was greater. A comparison test of catches revealed significant differences between the 0 cm position (rested on the ground) and the other two positions.
Conclusion
When creating a monitoring system for P. operculella trapping system, these results should be taken into consideration.

Authors: Kumar Vinod , Padsala Shailesh , Mayursing Girase , Ray Debes , Aswal Vinod Kumar , Kuperkar Ketan , Bahadur Pratap 
Published: April 2023

Abstract

Self-assembly and micellization performance of cationic conventional surfactant: tetradecyltrimethylammonium bromide (TTAB) and gemini surfactant (GS): N,N′-ditetradecyl-N,N,N′,N′-tetramethyl-N,N′-ethanediyl-diammonium dibromide (14-2-14) were investigated in water and water-trifluoroethanol (TFE) solvent mixture using tensiometry and small-angle neutron scattering (SANS) techniques. The micellization parameter critical micelle concentration (CMC) for our examined systems was evaluated at the air-water interface at 303.15 K using tensiometry. It was found that CMC of the cationic surfactants decrease with increasing the concentration of TFE thereby indicating micellization process getting influenced by the addition of surface-active TFE. The shape and aggregation number (Nagg) of the surfactant micelles were evaluated as a function of TFE using SANS which revealed the decrease in micelle size of cationic surfactants. In addition, the computational simulation study is undertaken to offer an insight into the interactions involved between the examined cationic surfactants and TFE system.

Published: April 2023

Abstract
Introduction/Background: Enterohaemorrhagic Escherichia coli (EHEC) O157:H7 is the most important serotype of E. coli responsible for serious intestinal and extra-intestinal disorders worldwide, but no molecular based study for EHEC as the causative agent diarrhea was performed in the Sudan. EHEC is a subset of Shiga toxin (stx) producing E. coli (STEC) which includes well recognized human pathogens. STEC produce high level toxins of a protein family referred to as Shiga toxin and Shiga-like toxins (SLTs; alternatively known as verocytotoxins VTEC or VTs). EHEC O26:H11 and O111:H8 have emerged as the most important non-O157:H7 EHEC.
These toxins are mediating intestinal disease in children and adults, and if the cases left untreated these toxins may contribution to the development of extra-intestinal sequelae e.g., the haemolytic uraemic syndrome and neurological disorders.
Objective: This study was conducted for the detection and molecular characterization of Shiga like toxin (stx) of E. coli O157:H7, E. coli O26:H11, and E. coli O111:H8 in Sudanese patients with diarrhea using PCR and multiplex PCR.
Materials and methods: A cross sectional laboratory-based study was carried out in Khartoum, Sudan during the period from June to October 2020. All patients with confirmed E. coli diarrheal disease was included in this study. The isolates have been identified by using the biochemical, serological, molecular identification and characterization tests. SPSS IBM (software version 20.0) was used for analyses.
Results: Out of 100 patients with diarrheal disease a total of 96 patients were confirmed of having E. coli organisms. All 96 E. coli bacteria were seropositive identified as members of the EHEC. Ten isolates of E. coliO157:H7, E. coli O26:H11, E. coli O111:H8 have been selected as follows; five, three, and two respectively.
The selected isolates followed by multiplex PCR to detect the genes of stx toxins of E. coli O157:H7, E. coli, O26:H11, and E. coli O111:H8 and comparing between them.
The multiplex PCR revealed that E. coli O157:H7 were carrying stx1 and stx2 genes represented by two bands, while E. coliO26:H11 and E. coli O111:H8 were carrying one stx2 gene represented by one band.
Conclusions: E. coli O157:H7 produce stx1 and stx2 while the other serotypes E. coli O26:H11 and E. coli O111:H8 produce stx2 only.
Effective control of pathogenic strains of E. coli requires a multifaceted approach. To reduce the frequency and severity of human exposure to STEC, controlling dietary sources and environmental sources such as cattle, water troughs, feed and manure is critical in breaking the cycle of infection and re-reinfecting with STEC.
Chaos control and numerical solution of time-varying fractional Newton-Leipnik system using fractional Caputo-Fabrizio derivatives
Authors: ALMUTAIRI Najat , Saber Sayed 
Published: April 2023

Abstract
In this work, a design of a constant and time-varying fractional Newton-Lepnick system is developed to understand its chaotic properties. Due to the nonlocal nature of the method, the Newton-Leipnik system is generated using a generalized power law, a power law and another fractional derivative based on the Mittag-Leffler function developed as a kernel. We solve the model using the numerical Caputo-Fabiesu method, but also test their existence and uniqueness. These schemes are applied to oscillators of chaotic Newton-Lepnic systems based on simulated chaotic circuits. Chaos control is performed by a linear controller. Furthermore, the Lyapunov exponent of the system indicates that the chaos control results are correct. We demonstrate the applicability and effectiveness of this method with a numerical example. Numerical simulation of the controller is provided.

Novel Meta-Heuristic-based Drone Squadron Optimization Fast Charging Strategy for Battery Packs in Electric Vehicles
Authors: Manas Munish , Dubey Rajesh Kumar , Yadav Ravish 
Published: April 2023

Abstract
Faster lithium-ion battery (LIB) charging is one of the factors that have increased public acceptance of electric vehicles (EVs), yet high-rate charging can cause permanent LIB system deterioration and safety issues, even if it is within physical limitations. Motivated by this, this study proposes a novel approach for achieving optimal fast charging of batteries by utilizing a drone squadron optimization (DSO) technique. The technique considers various factors, including battery capacity, temperature, voltage, and state-of-charge (SOC) to optimize the charging process. The proposed approach uses a hierarchical control framework that optimizes the charging schedule and considers the charging capabilities of individual batteries and the overall system constraints. Simulations were conducted to evaluate the performance of the proposed technique, and the results demonstrated that it can significantly reduce the charging time of batteries while improving their overall efficiency. The technique also ensures that the charging process is conducted within the recommended temperature and voltage ranges to avoid damage to the battery. The proposed DSO technique can be useful in various applications that rely on battery-powered devices, where fast charging times are essential for operational efficiency.
A modified Taylor diagram to improve the comparison of models
Authors: Ghorbani Mohammad Ali , Khatibi Rahman , Ruskeepää Heikki 
Published: April 2023

Abstract
The Taylor diagram is modified in this paper to offer a new model performance metric: the distance of the modelled results to observed statistics. Traditionally, the Taylor diagram is used to compare several models in terms of the shortest distance from the modelled results to the observation point based on visual locations of their RMSE and correlation coefficients. The modified Taylor diagram calculates the distances and shows them in an accompanying table to facilitate their discrimination even if the points are too close. The new metric is tested in a hydrological study of the relationship between evaporation and minimum temperature at a station in Australia. A stringent testcase is presented, in which 10 selected model performances are quite close but the new metric discriminates their performances and facilitates learning. The efficacy of the study provides a proof-of-concept for the new metric in hydrology and applies to any other data-driven models.
