Chronic kidney disease (CKD) is a severe medical disorder manifested by a decline in kidney function over an extended period. This leads to the accumulation of toxins and the gradual inability to remove excess waste and fluids from the body. Microtubule-associated protein 2 (MAP2) is part of a protein family that regulates microtubule structure and cellular metabolism. This study aims to analyze the effectiveness of these parameters in evaluating CKD and its associated mechanisms in Iraqi patients. The study was conducted from December 2023 to May 2024. Ninety subjects enrolled in this study: 60 patients with CKD who attended the Baghdad Teaching Hospital/Medical City/ Dialysis Unit in Baghdad, Iraq. Additionally, 30 healthy sub

Dental caries, also named tooth decay, is a major issue for oral health and is caused by bacteria in dental plaque. Detecting caries early on is essential for preventing further damage. Because caries are often small, they can lead to unnecessary treatments or missed diagnoses. This study tackles the challenge of spotting dental caries using color image analysis. We tested both traditional methods—like Quickshift, Simple Linear Iterative Clustering (SLIC) superpixels, and k-means clustering—combined in the Multi-Step Segmentation with K-Means (MSS-KM) approach, as well as a more advanced deep learning method using YOLOv12 for segmentation. The evaluation of the performance of these methods based on accuracy, precision, recall, mean a

In this work, two carrier concentrations with dye D102 were used in a dye-sensitized solar cell to perform a comparative evaluation of the efficiency and influence on the study of key parameters affecting the device performance. To achieve this goal, the cell transfer power, current, current density and fill factor were calculated to estimate the power conversion efficiency (PCE) of DSSCs. Electrons move from the excited state of indolene D02 to the conduction band of ZnO to produce current for DSSCs through the assumed energy levels of donor indolene and acceptor ZnO in the hetero junction device to be continuous. The effect of carrier concentration and coupling strength on the improvement of the contact efficiency of D102 hetero juncti

The sol-gel method was used in this study to create the Zn-CdFe₂O₄/SnO_2(0.15) nano ferrite, and XRD, FE-SEM, and EDX methods were used to evaluate the nano ferrite's characteristics. The findings showed that the lattice constant of the sample CdFe₂O₄/SnO_2(0.15) is higher than that of ZnFe₂O₄/SnO_2(0.15) and Zn_0.5Cd_0.5Fe₂O₄/SnO_2(0.15) and that the resultant compound possesses a cubic spinel ferrite phase. The crystal size was on the nanoscale, according to Scherrer-Williamson Hall. Based on the FE-SEM images, it can be noticed its shape as semi-spherical or spherical; the prese

An unsaturated polyester's (UPE) mechanical and thermal properties were modified by incorporating nanosized titanium dioxide (TiO₂) particles with 1, 2, 3, 4, and 5% weight ratios. 3% of TiO₂ is the best weight percentage that can be added to UPE to improve its impact strength from 8.74 MPa to 8.87 MPa, its hardness value from 82.23% to 86.63%, its tensile strength from 7.698 MPa to 24.76 MPa, and its thermal conductivity from 0.308499 W/m.^oC to 0.566916 W/m^oC. Also, the thermal stability of UPE/3% TiO₂ was improved using thermogravimetric analysis (TGA). XRD measurement was employed to verify the change caused by adding TiO₂ particles to the internal structure of unsatura

Rheumatoid arthritis (RA) is a systemic disease that causes chronic inflammation, primarily affecting the synovial joints in the hands and feet. Laboratory investigations, such as  C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), lipid profile, and matrix metalloproteinase-1 (MMP-1), evaluate the body's inflammation level. Rheumatoid arthritis is generally progressive, causing fatigue and weakening of the muscle joints. Despite recent treatment improvements, there is no known cure for RA. The study aimed to find the role of chemokine MMP-1 as a biomarker in serum samples of 80 patients with RA and 40 healthy subjects. The mean of MMP-1 was significantly higher in patients with RA compared to the control group (MMP-1: 3.27

Complex systems in the real world have networks differ significantly from random graphs and have non-trivial structures. In fact, they have a community structure that needs to be recognized and recovered. The stochastic block models (SBMs) are popular models for community detection in networks, where nodes are divided into groups based on their connectivity patterns. Maximum likelihood estimation is a common method for estimating the parameters of SBMs. In this paper, a model selection for stochastic block models is presented based on the optimization of the log-likelihood function to find the best number of communities K detected by the regularized convex modularity maximization method. This work deals with many assumptions on K because
