https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4391
<p>Information hiding is one of multimedia security tasks need to develop and update in Continuously. Thus, the researchers work in this field and interest in developing and improving the information hiding techniques. In this paper, a new method for develop least significant bits (LSB) method is introduced. The method includes a schema for hiding two bits of secret text in each pixel (least and penultimate bits of pixel) in gray image considering motif Z, U, N, and C patterns. The method is implemented on different standard images with size 512*512 and hide different secret text lengths. The experimental and results show the efficiency of method that hide two bits in each pixel compare with the traditional LSB method that hide one bit of data in each pixel of image. The results show that the proposed method produces a good accuracy of stego image near to the original LSB method in terms of PSNR accuracy metric.</p>Elaf Ali AbboodRafeef Mozher Ketran

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4394
<p>Information security is a major source of worry, especially in light of the rapid expansion of internet use in recent years. As a result of this expansion, there have been incidences of illegal access, which have been mitigated by the adoption of a variety of secure communication protocols, including encryption and data concealment. DNA's bio-molecular properties have seen an uptick in popularity as a carrier for cryptography and data hiding in recent years. when information needs to be hidden. Therefore, DNA bases are utilized as information carriers in the data concealing strategy to increase safety. DNA-based steganography and cryptography combine a biological property with conventional methods to provide an algorithm with increased security. Because of their ability to maintain their chemical and biological characteristics, DNA sequences also have a high data capacity.</p>Defaf Shiker KadhumSahar Adil Kadhum

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4395
<p>Background:</p> <p>In this paper, we aim to improve community detection methods using Graph Autoencoder. Community detection is a crucial stage in comprehend the purpose and composition of social networks.</p> <p>Materials and Methods:</p> <p>We propose a Community Detection framework using the Graph Autoencoder (CDGAE) model, we combined the nodes feature with the network topology as input to our method. A centrality measurement-based strategy is used by CDGAE to deal with the featureless dataset by providing artificial attributes to its nodes. The performance of the model was improved by applying feature selection to node features</p> <p>The basic innovation of CDGAE is that added the number of communities counted using the Bethe Hessian Matrix in the bottleneck layer of the graph autoencoder (GAE) structure, to directly extract communities without using any clustering algorithms.</p> <p>Results:</p> <p>According to experimental findings, adding artificial features to the dataset's nodes improves performance. Additionally, the outcomes in community detection were much better with the feature selection method and a deeper model. Experimental evidence has shown that our approach outperforms existing algorithms.</p> <p>Conclusion:</p> <p>In this study, we suggest a community detection framework using graph autoencoder (CDMEC). In order to take advantage of GAE's ability to combine node features with the network topology, we add node features to the featureless graph nodes using centrality measurement. By applying the feature selection to the features of the nodes, the performance of the model has improved significantly, due to the elimination of data noise. Additionally, the inclusion of the number of communities in the bottleneck layer of the GAE structure allowed us to do away with clustering algorithms, which helped decrease the complexity time. deepening the model also improved the community detection.

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4396
<p>Background:</p> <p>Handwriting recognition is an important issue nowadays, where handwriting can be a image, document, etc., the ability of a computer to recognize handwritten numbers is very important in more than one application such as translation, reading and number recognition applications. The proposed project provides a system that recognizes handwritten English numbers, the input data being images downloaded from a global dataset. The proposed system consists of a number of stages. The first stage is the preprocessing, which includes resizing of the images to be one size (28 * 28), and then a step (data mapping) is applied. As for the classification stage, it relied on the use of two algorithms, the KNN algorithm and the neural network (error backpropagation). To start the process of training the selected algorithms, the data was divided into two sets, the training setand the test set. Two algorithms were used for the purpose of choosing the best of them, by evaluating their performance using a number of evaluation metrics. Accuracy and Precision were used for the purpose of evaluating the performance of the algorithms. The performance of the KNN algorithm was 0.94 and 0.942 respectively when k = 4. While the best performance reached by the neural network mechanism was 0.98673333 and 0.9698, respectively, at epoch = 15. The neural network (error backpropagation) is shows the best result in the recognation stage</p> <p>Materials and Methods:</p> <p>K-Nearest Neighbors (KNN) technique makes no assumptions about the basic dataset. It is recognized for its effectiveness and ease of use. It is a supervised learning algorithm. To estimate the category of the unlabeled data, a labeled training set containing data points separated into many groups is supplied.</p> <p>Results:</p> <p>The performance of the KNN model with various values for "K." Since the high value of model accuracy was "0.94", the "4" parameter value is the one that provides the best results and precision was "0.94".</p> <p>Conclusion:</p> <p>The problem of handwritten recognition needs high accuracy and precision indicators show an accurate description of the performance of the algorithms that were employed in the proposed system. The two indicators described the performance of the algorithm (KNN), which gave results (0.94 and 0.942).</p>Ali Abdul Kareem Salman AL-YassariHadab Khalid Obayes

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4397
<p>Information security is a significant cause for concern, mainly because of the explosive growth in internet usage over the last few years. Due to this growth, there have been occurrences of unauthorized access, which have been reduced thanks to “using a range of secure communication protocols, such as encryption and data concealment”. Using DNA's bio-molecular capabilities, the usage of DNA as a carrier for encryption and data concealing has increased in recent years. The realization that DNA may function as a transport medium sparked this movement. In this study, we first examine and briefly outline the evolution of the present DNA coding system. After that, the several ways DNA has been used to enhance encryption techniques are categorized. The benefits and drawbacks of these algorithms and the most recent advancements in DNA-based encryption techniques are discussed. Finally, we provide our thoughts on the potential future of DNA-based encryption algorithms.</p> <p> </p>Hiba Safaa Sahar AdillAli Yakoob

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4399
<p>Monkeypox virus appeared in the countries of Central and West Africa. Two distinct species have been identified, the West African type and the Congo type, also known as the Central African type.In the outbreak of monkeypox was first discovered in 1958, while the first human case of the disease was diagnosed in 1970 in the Republic of the Congo in a 7-year-old child. The incubation period ranges from 5-21 days.Monkeypox is transmitted to humans by contact with the virus that causes it through;Mouth and contact with infected animals, including mice, rats, and squirrels, common for monkeypox transmission in Africa, during animal bites from infected animals to humans. Touching the fur or skin of animals, or what comes out of them from blood or bodily fluids. In the case of monkeypox, the virus is transmitted from the mother to the fetus. The main symptoms of monkeypox are similar to the symptoms of smallpox, but they are milder, with the only difference being swollen lymph nodes, fever, headache, backache, cough, sore throat, stuffy nose, fatigue, exhaustion and sweating. The rash of monkeypox begins to appear after 1 - 3 days from the patient with fever, which appears on the face first, then the body begins to spread to the rest of the parts, such as the hands, legs, inside the mouth, genitals, conjunctiva, and the cornea. A complication of monkeypox is Secondary bacterial infection, such as pneumonia, encephalitis, and eye infection.</p>Mohammed R. AbdAliAmeera JasimNada Khazal K. Hindi

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4411
<p>Still, external insulin therapy with its various types causes a variety of immune reactions through its variable control of the glucose level in patients with type 1 diabetes. However, major immune problems are uncommon, and less serious diabetic events have long-term effects on immune responses. The current study aimed to follow up the effect of glucose levels on the level of gene expression of the <em>FoxP3</em> gene, one of the most important genes responsible for the activity of Regulatory T cells in patients with type 1 diabetes. (26) blood samples were collected from individuals diagnosed with type 1 diabetes for a period of more than (5) years, their ages ranged from (15-35) years, and from both sexes, from Al-Wafa Center for the treatment of diabetics and endocrine glands in the city of Mosul. The patients were divided into four groups, depending on the type of insulin injection , These groups included (Actrapid patients group, Insulatard patients group, Insulatard / Actrapid patients patients group, and finally Mixtard patients group). The control group also included (7) blood samples of healthy people as donors, ages ranging from (15-30) years, (males and females), without communicable diseases, bacterial infections, or autoimmune diseases. . The results showed an effect of glucose concentration on the expression level of the <em>FoxP3</em> gene by (26%) in the group of patients who used insulin mixtard type, while the results of the effect analysis of glucose on the level of gene expression of the <em>FoxP3</em> gene showed a rate of (76%) in the group of patients who used insulin type Insulatard, On the contrary, there was no effect of glucose concentration on the level of <em>FoxP3</em> gene expression in patients using Actrapid and Insulatard / Actrapid insulin at (P≤0.05).</p>Saad Imrrer Ali Rojan G.M.

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4416
<p>Various authorities are keen to preserve the confidentiality of their information and protect it from competing or hostile parties who were also keen to access that information by all available means. Since the encryption of information is exposed as it produces incomprehensible texts that arouse suspicion, some tend to work in a way that removes suspicions by hiding the information in a medium like text or picture so that what is sent and circulated appears natural and free of signs or incomprehensible symbols as if not loaded with any additional information. This paper introduces a review the techniques used to hide data in images as one of the most common concealment techniques.</p>Noor Kadhim AyoobAsraa Abdullah Hussein

Fifty ovaries were collected from Karbala and Najaf butcheries for two seasons: the first season (August 2021) and the second season (January 2022). Moreover, collected follicles were divided according to their sizes into three groups (first group < 3 mm), (second group 3-5 mm), and (third group > 5mm) The results showed a significant increase (P ≤ 0.01) for protein, glucose, cholesterol, and sodium, and a significant increase (P ≤ 0.05) for calcium in the first season compared to the second season, and the significant increase was (P ≤ 0.05) for potassium in the second season compared to the first season. As for the follicles sizes the result exhibited, there were highly significant differences in the size of the follicles for the first group (< 3 mm ) P≤0.01, as it reached in the first season 8 (32.00%) and in the second season 13 (52.00%) and also found highly significant differences in the size of the follicles for the second group (3-5 mm) 11 (44.00%) in the first season and 6 (24.00%) in the second season (P≤0.01). for the follicles of the third group (> 5mm), there were no significant differences, as it reached 6 (24.00%) in the first season and 6 (24.00%) in the second season. The groups also differed significantly within the same season. The highly significant increase for the second group was (P≤0.01) compared to the rest of the groups within the first season, while in the second season, the high significant increase was for the first group (P≤0.01) compared to the rest of the groups.</p>Rajaa F.

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4456
<p>In this paper, we suggested two new techniques for transforming multi-objective linear fractional programming problems into single-objective linear fractional programming problems (SOLFPP) and then solving them by methods of SOLFPP. Illustrative numerical examples are presented for demonstration purposes. Also, the obtained results are compared with another method studied previously. </p>Snoor O. Abdalla Ronak M. Abdullah

https://www.journalofbabylon.com/index.php/JUBPAS/article/view/4480
<p>The ability of <em>Trichoderma viride</em> to synthesize extracellular enzymes (Lacase enzyme) using a substrate that contains media was examined. This isolate generated laccase at its greatest level (0.166U/ml) in liquid medium. This study was demonstrated the production, purification, and characterisation of the laccase enzyme from <em>T.viride</em>. The results showed that 96 hours was the optimum period of time for Laccase to incubate from this fungus. Laccase displayed the maximum level of activity at pH 4.5 and temperature 30 °C. The results revealed that the best ratio for laccase precipitation was 90% by using ammonium sulphate<em>.</em> In addition, for the purification of laccase enzyme, one peak of Laccase was appeared in gel filtration purified from <em>T.viride</em>, while 2 peaks of Laccase were seen in ion exchange chromatography. According to the findings, the molecular weight of <em>T. viride</em> Laccase using SDS-PAGE was roughly 66KD under denaturation conditions.</p>Liqaa Y.
