Molecular and Microscopic Diagnosis of Entamoeba histolytica in Human Stool Samples from Al-Kut, Iraq
type: item
description: Entamoeba histolytica, a protozoan parasite, is responsible for amoebiasis, a significant public health issue, particularly in developing regions where sanitation and sanitary infrastructure are frequently insufficient. It is imperative to have a precise and expeditious diagnosis in order to effectively manage the patient and prevent the transmission of the infection. Our objective in this investigation was to assess and contrast the diagnostic efficacy of two methods for the detection of Entamoeba spp. in stool samples: conventional microscopic examination with Lugol's iodine staining and molecular identification via multiplex polymerase chain reaction (PCR) that targets the 18S rRNA gene. At the Al-Kut and Al-Karama hospitals in Wasit Province, Iraq, a total of 67 stool samples were obtained from patients who were experiencing gastrointestinal symptoms, particularly diarrhea. The positivity rate for Entamoeba spp. was 67.2%, as evidenced by the microscopic examination, which revealed spherical cysts with clearly defined nuclei. On the other hand, conventional PCR-based molecular analysis identified E. histolytica in 80% of the tested samples, indicating a greater diagnostic yield. Significant differences between the two methodologies were verified through statistical analysis (P ≤ 0.05). The findings emphasize the superior sensitivity and specificity of PCR for accurate detection and demonstrate the limitations of microscopy in differentiating morphologically similar species within the Entamoeba complex. This research advocates for the inclusion of molecular diagnostic methods, such as multiplex PCR, in routine parasitological screening, particularly in endemic regions. In addition, the results establish a basis for enhanced diagnostic strategies and public health interventions that are designed to manage amoebic infections.

type: item
description: This paper presents new results concerning coincidence and common fixed points in the setting of fuzzy Fréchet spaces, making essential use of the triangular inequality inherent in such spaces.to illustrate the applicability of the theoretical results, a concrete example is provided. Moreover, the established findings are employed to investigate a class of fuzzy differential equations, where we demonstrate the existence and uniqueness of a common fixed point for a triplet of operators. This fixed point corresponds to the unique solution of associated fuzzy differential system. The proposed approach opens new perspectives in the study of fuzzy dynamic systems and may serve as a foundation for extending similar results to broader classes of compatibility conditions and fuzzy differential models.

Enhancing Cloud Resource Allocation with a Deep Learning-Based Framework
type: item
description: Cloud computing has transformed the modern world of computing by enabling the provisioning of resources that are on demand and scalable. Nevertheless, the issue of efficient resource allocation persists due to unpredictable demand fluctuations and heavy duties. This paper investigates the allocation of cloud resources through the use of deep learning (DL) models, specifically Convolution Neural Networks (CNNs), Gated Recurrent Networks (GRNs), and Long Short Term Memory (LSTM) networks. CNNs acquire spatial patterns from cloud workload data, while GRNs acquire short-term resource usage dependency patterns. By acquiring long term patterns in work load variation, LSTMs further improve the accuracy of their predictions. Our proposed framework optimizes cloud resource allocation using these models, enhancing overall system performance, reducing energy consumption, and reducing latency. Experimental evidence indicates that our proposed deep learning framework is more precise and adaptable than conventional methodologies.

Coronary Artery Blockage Identification and Severity Classification using a hybrid convolutional neural network (CNN) model
type: item
description: Abstract The cardiac diseases are considered a major health problem. Therefore the early identification and detection of the heart issues is an important procedure. Technology plays a significant role in this health issue. It is an ideal means that helps experts to diagnose the heart problems. The Coronary Artery Analysis is a medical heart test that checks the coronary arteries. The medical imaging techniques of the MRI, and CT scans are used to identify abnormalities such as blockages, narrowing, or other structural issues. This analysis helps assess the severity of coronary artery disease (CAD) and guides treatment decisions to improve heart health. This research presents a hybrid convolutional neural network (CNN) model integrated with sophisticated optimization approaches for the analysis of heart/MRI ultrasound images. The research utilizes a hybrid approach of Gradient Boosting (GB) and Support Vector Machine (SVM) classifiers to detect coronary artery abnormalities. The suggested methodology precisely identifies Coronary Artery Blockages (CAB) in medical imaging and delineates regions of concerns. In the next phase, a tailored CNN classifier is employed to quantify the dimensions of obstructions, encompassing their length and severity, so facilitating accurate anomaly evaluation for diagnostic assistance in healthcare environments.

Synthesis of Enaminothiones and Computational Investigation of Intramolecular Hydrogen Bonding Strength and Substituent Effects Using DFT, QTAIM, and NCI.
type: item
description: Enaminothiones were prepared, and the effects of aromatic and aliphatic substitutions on the strength of intramolecular hydrogen bonds were studied via DFT calculations (ωB97XD/6‐311++G(d,p)), QTAIM and NCI analyses. The results showed that aromatic substitutions enhance the strength of hydrogen bonds, as they result in shorter S…N distances, higher electron density (ρBCP), and stronger hydrogen bond energy (35.80–36.69 kJ/mol) than those of aliphatic compounds. NMR measurements confirmed this with greater chemical shifts of the NH proton in aromatic compounds (15.74–15.88 ppm), and NCI analysis revealed more negative sign(λ2)ρ values, indicating stronger bonding. This study confirms the role of substitutions in modifying the strength of hydrogen bonds, which may have an impact on the design of pharmaceutical compounds and chemically active materials.

Digital Self-Interference Cancellation Using Convolutional Neural Networks in In-Band Full-Duplex Systems
type: item
description: In-band full-duplex (IBFD) communication systems represent a major breakthrough in wireless communication, allowing transmission and reception of signals on the same channel simultaneously. However, a critical challenge in IBFD systems is mitigating Self-Interference (SI), which results from the leakage of the transmitted signal into the receiver, potentially overwhelming the received signal and degrading overall system performance. This paper investigates the application of Convolutional Neural Networks (CNNs) for digital Self-Interference Cancellation (SIC) in IBFD systems. We propose a CNN architecture consisting of three convolutional layers, designed to learn and suppress the nonlinear characteristics of self-interference effectively. Simulation results demonstrate that the proposed CNN-based SIC method achieves 52.492 dB interference suppression at an SNR of 30 dB, significantly improving the bit error rate performance compared to conventional methods.

Production of single cell protein Using Mixed Microbial Inoculum Technology from Two Local Bacterial Isolates, Kytococcus sedentarius, and Pseudomonas oleovoran, Using Solid Medical Waste
type: item
description: This research was conducted to produce single-cell protein using a mixed inoculum of two local bacterial isolates, namely Pseudomonas oleovorans and Kytococcus sedentarius. The submerged culture technique was used in the production process using the double inoculum. After initial treatments, solid medical waste was used as the main carbon and energy source in the nutrient medium on which the two bacterial isolates were grown. Production optimization experiments were conducted to reach the best production of single-cell protein. The production optimization experiments aimed to reach the best conditions for optimal production. These experiments included studying the effect of each factor (PH, temperature, inoculum size, type and concentration of nitrogen source, and the effect of incubation duration). Optimizing the production conditions showed that the best single-cell protein production was at PH9, temperature 45°C, and inoculum size 2 ml of each of the two isolates/100 ml of the production medium. The best production was achieved using NaNo3 at a medium concentration of 0.3 g/100 ml. Finally, the best production was obtained at an incubation period of 72 hours. After applying the optimum conditions, the best single-cell protein production was 1.712 g/100 ml of the production medium. The analysis and separation of the culture filtrate after single-cell protein extraction using gas chromatography (GC-MS) technique showed that this filtrate contains 15 active chemical compounds with vast and valuable applications. These compounds are Chloro-3,3-dimethyl-8--6phenyl-3,4-dihydro-1H-thiopy, Neopentane, Oxadiazole, 5-(4-tert-[1,2,4]butylphenoxymethyl)-3-(thiophen-2-yl)- and (4-Methoxyphenyl)-2-(4--2 trimethoxysilyloxy)propane and Methane, isocyanato And Silane, dimethyl(2-chloro-5-methylphenoxy)heptyloxy and Propanoic acid, anhydride and N, N'-(4-Methyl-m-phenylene)bis(p-toluenesulfonamide) and 1,3-Propanediamine and Vitamin E and Silane, dimethyl(2-chlorophenoxy)octyloxy …

Equine Lameness: an Advanced Review of Classification, Diagnostics Methods Especially with Local Anesthesia, and Management Strategies
type: item
description: Equine lameness, defined by an abnormal gait that impairs movement, is a significant concern in equine health with economic, ethical, and welfare implications. It results in increased veterinary expenses, decreased performance, and reduced horse value, particularly in equine sports, where welfare considerations are paramount. While mild lameness may appear self-limiting, unresolved cases can progress to chronic conditions such as laminitis and musculoskeletal disorders, often causing compensatory strain on the contralateral limb. The pathophysiology of lameness is multifaceted, encompassing biomechanical, orthopedic, and environmental factors, necessitating precise pain assessment for accurate diagnosis and effective treatment. Clinically, lameness is identified through gait abnormalities and localized tenderness, often relying on subjective evaluations; however, advancements in motion analysis technology have improved diagnostic accuracy. Management strategies focus on pain alleviation, disease progression control, and enhancing overall quality of life, particularly in chronic conditions such as osteoarthritis. In severe cases, lameness may lead to euthanasia due to significant functional impairment. Additionally, horses may instinctively mask pain, complicating clinical assessments. A comprehensive literature review was conducted using PubMed, Scopus, and Google Scholar, employing targeted keywords to ensure the inclusion of relevant studies.

This study aimed to assess the biological response of human colon cancer cells subjected to a single laser irradiation dosage (2.5, 5, 7.5, and 10 J/cm2). After seeding human colon cancer cells onto laboratory plates, various dosages of an 808 and 635 nm laser were used to irradiate their exposure at 70 milliwatts, cells exposed to radiation were then incubated for one day. Changes in cell proliferation have been examined using MTT (3-(4,5-Dimethylthiazole-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) assays. The viability of cells was decreased in nm-irradiated cultures than in control cultures. The results showed that doses of 2.5, 5, 7.5, and 10 J/cm2 were sufficient to cause visible alterations in colon cancer cells.

Study the Effect of Phosphorous Impurities on Electronic and Optical Properties of Circumcoronene via DFT investigations
type: item
description: The electronic and optical characteristics of circumcoronene are significantly impacted by phosphorus doping. Improved stability, smaller energy gaps, and changed Fermi levels are some of the main results, which make these doped systems attractive options for use in energy devices, photonics, and nanoelectronics. Phosphorus doping significantly alters the chemical indices of circumcoronene, increasing its stability, reactivity, and suitability for uses requiring robust electron interaction. The design of nanoscale materials, including catalysts, sensors, and energy-storage devices, will be significantly impacted by these discoveries. The structures can be appropriate for applications that need absorption in the far-infrared or electronic devices with decreased optical loss by modifying the high-energy transitions with a considerable oscillator strength. The optical characteristics of circumcoronene are markedly altered by phosphorus doping, as seen by longer absorption wavelengths, lower transition energies, and weaker oscillators. Because of these changes, phosphorus-doped circumcoronene retains its adjustable electronic behavior for certain optoelectronic applications while being extremely versatile for usage in infrared photodetection, optical sensors, and energy storage.

Detection of the presence of both species Sinanodonta woodiana and Sinanodonta lauta in the recent sediment of Southern Iraq
type: item
description: The selection of the study area was influenced by the recent discovery of new pelecypod species documented for the first time in southern Iraq. Sixteen samples were collected from seven locations situated on both banks of the Euphrates River, northwest of Basrah Governorate. An analysis was conducted to identify the types of sediments at these sites, alongside the various shell species present in the region. The findings revealed that mud sediments predominated over other sediment types, which included silt and sandy mud. Within the study area, two pelecypod species were identified: Sinanodonta lauta and Sinanodonta woodiana, along with a barnacle species, Amphibalanus subalbidus. The presence of these species suggests that the area has been influenced by environmental changes that transpired towards the Late Holocene period, as all identified species interduced from outside the region's native ecosystem.

Improving Network Security by Applying Unsupervised Machine Learning Techniques
type: item
description: Computer networks are increasingly exposed to sophisticated and diverse attacks, threatening the security of data and services. The difficulty lies in detecting new and unknown attacks, especially with the increasing volume and size of network traffic. This research seeks to address this problem by developing a network event detection system based on unsupervised methods, which enables it to detect abnormal behavior patterns that may indicate the presence of an attack. This research aims to develop an innovative network event detection system using unsupervised learning techniques, It achieved 95% detection accuracy and reduced the false alarm rate by 30% compared to traditional systems. This method distinguishes itself from traditional event detection techniques in its ability to effectively detect new and previously unknown network behaviors. This is done by relying on unsupervised learning methods and analyzing bidirectional network flows. Comparing the performance of several algorithms within this method contributed to improving the detection accuracy. In addition, the method is designed to handle large amounts of data, making it suitable for real networks. The system relies on analyzing bidirectional network data flows (Biflow) to extract abnormal behaviour patterns that may indicate the presence of security threats. Unsupervised clustering algorithms, such as k-means, x-means, and self-organizing Kohonen neural networks, are used to achieve this goal.

A High-Gain Slotted Rectangular Microstrip Patch Antenna for 5G Millimeter-Wave Applications
type: item
description: The fifth generation (5G) of telecommunications has been a compelling subject for several academics in recent years. A patch antenna has recently been used for 5G technology, which demands a communication connection with a high data rate and low latency. This article proposes a high-gain slotted microstrip patch antenna for 5G applications at the resonant frequency of 38 GHz. Rogers RT5580 material, with a dielectric permittivity of 2.2 and a loss tangent of 0.009, has been used as a substrate for the antenna. The antenna in concern has a compact construction with dimensions of 8×5.2×0.324 mm³. The slotted antenna's dimensions are optimized with the CST Studio Suite software simulator. The proposed antenna design achieved a reflection coefficient of -49.9 dB, a gain of 9.233 dBi, and a wide operational bandwidth of 1.84 GHz, which is the main objective of this study. The suggested antenna also demonstrated favorable performance at 37 GHz and 39 GHz by changing the length of the radiation patch. In comparison to previous similar designs reported in the literature, the proposed antenna has significantly higher bandwidth, return loss, beam gain, and radiation efficiency; therefore, it is a viable alternative for 5G communication.

type: item
description: One hundred and twenty dental caries samples were collected during the period between September 2023 and January 2024. Streptococcus mutans were isolated and diagnosed based on cultural, microscopic characteristics, and biochemical tests such as IMViC and the Remel RapID STR system. Obtained results showed that 64 isolates (53.4%) belonged to the genus Streptococci and that 40 isolates (62.5%) of this genus belonged to the species Streptococcus mutans, while 56 isolates (46.6%) of the total 120 isolates did not belong to the genus Non-Streptococci. Silica nanoparticles (SiO2 NPs) was prepared using the aqueous extract of Glycyrrhiza glabra (licorice) root extract and characterized using UV-Visible spectra, X-ray diffraction (XRD), and FESEM. SiO2 NPs showed absorbance peak at 497 nm. The XRD pattern showed that the strong four intense peaks indicate crystalline nature and face centered cubic structure of silica nanoparticles. Field emission scanning electron microscope (FESEM) was used to study the morphology of the SiO2 NPs. It exhibited a spherical shape with diameters of 46 to 77 nm. The obtained results of antibacterial activity showed that the prepared SiO2 NPs were effective against the isolated Streptococcus mutans, as the minimum inhibitory concentration (MIC) value was 12.5 units/mL, and the minimum bactericidal concentration (MBC) value was 25 units/mL.
