In this paper, we propose modifying the VGG16 architecture to improve its performance in the classification task. We utilize the Acute Lymphoblastic Leukemia (ALL) image dataset to train the proposed modified VGG16 model. The dataset was split into training and testing sets at a ratio of 80% for training data, 10% for validation data, and 10% for testing data. The ALL dataset consists of four classes: Benign, Early, Pre, and Pro. The results of the proposed modified VGG16 model were very satisfactory: accuracy, 96.59%; precision, 96.61%; sensitivity, 96.59%; F1-score, 96.58%; and Matthe

The synthesis involved combining N-(4-aminophenylsulfonyl) benzamide (also known as sulfabenzamide) with indoline-2,3-dione. To facilitate the reaction, three drops of glacial acetic acid were added. This process yielded the ligand N-(4-(2-oxoindoline-3-ylideneamino) phenylsulfonyl) benzamide, designated as (L). Mixed ligand complexes were prepared in a molar ratio (1:1:1) (M:1,10-phen, L) at concentrations of 10-4M by interacting L and 1,10-phenanthroline, with the following metal ions (Cr+3, Mn+2, Zn+2, Pd+2, Cd+2, Pt+4).

The coupled nonlinear differential equations, which represent the motion of dust and fluid molecules, are formulated. These equations are solved by using the perturbation method with the help of the mathematics package; we obtained an approximate analytic solution. The impact of different kinds of parameters, like the Prandtl number, Renold number, wave number, second-grade parameter, Hartman number, wave length, permeability of the medium, and Darcy number, is discussed on the fluid velocity, fluid temperature, flow pattern, dust particle flow pattern, and
... Show MoreThis study investigates the instability of power-law fluids in a porous channel, emphasizing dual component convection influenced by gravity variations and vertical throughflow. A single-term Galerkin approximation is employed to derive critical Rayleigh numbers and neutral stability curves. The findings reveal that the power-law index tends to destabilize the system, affecting the neutral stability curves, while buoyancy forces contribute to enhancing stability. The role of gravity variations is highlighted as a critical factor, with exponential-type fluctuations proving more effective at achieving stability compared to linear-type fluctuations. Overall, the study emphasizes that key parameters, including the power-law index, buoyancy f

In this paper, some new results on common best proximity points for non-self-mappings are obtained in these spaces. It is an extension of previous results proven in classical complex metric spaces. The requirements of the work are as follows: first, we present some equivalent statements for convergence and Cauchy sequences. Second, we define complex b- rectangular metric space by using the function distance of a recent space. Finally, we present the concepts of commute proximity, weak - property and weakly dominate mappings. These concepts are illustrated by some examples. Furtherm

Show MoreThis study shows how the structural and dielectric properties of (SnO2)1-x(Mn2O3)x, (where x=0.00, 0.03, 0.05,0.07, and 0.09) prepared using the solid state reaction technique, are affected by the doping of semiconducting metal oxide Mn2O3. Structural analysis of the composites was carried out using information from the composite samples obtained from X-ray diffraction (XRD). The diffraction peak shifting in XRD patterns indicated that Mn ions were successfully incorporated into the SnO2 crystal lattice. Mn ions were successfully doped in the Tin oxide matrix lattice with the subsequent increase of doping levels. The average crystal size evaluated usi

Characterization results confirmed the successful integration of ZnO and TiO2 nanoparticles onto g-C3N4 nanosheets, resulting in enhanced optical absorption in the visible light region. Both synthesized ZCN and TCN composites exhibited higher photocatalytic degradation efficiency of the antibiotic doxycycline under visible light irradiation compared to their individual component materials. This enhancement is attributed to the formation of heterojunction between TiO2 or ZnO and porous g-C3N4

In our model, we divided susceptible individuals into two separate groups: one for high-risk individuals and another for those at low risk. In this work, we have proved theorems about the non-negativity and boundedness of the solutions. Afterward, we obtained a disease-free equilibrium point and an endemic equilibrium point. We calculated the basic reproduction number using the next-generation matrix method and then we expressed theorems about the local and global stability of equilibria, finally, we have gone to the sensitivity analysis and numerical analysis.

This paper's primary goal is to present the connection between coding theory and the projective space PG(5,q) of order q, where q={2,3,4,5,7,8,9,11} It was determined whether or not the [n,k,d]-code is perfect. Where n is the length of the code, k is the code dimension, and d is the minimum distance, were calculated with error correction e according to the incidence matrix. We have found that the [n,k,d]-code in PG(5,q), q= {2,3,4,5,7,8,9,11}, is perfect if e = 1.
A field experiment was conducted in the fields of the University of Baghdad to determine the effect of clover residues mixed with the soil in which the barley crop (Arviat variety) was planted. Residues of two varieties of clover (Red clover and Egyptian clover) were added at a rate of 3 and 6grams of plant residues. Two control treatments were also implemented with 3 and 6 grams of barley straw for comparison purposes. The results showed that the clover residues significantly reduced the germination and growth of the barley crop. However, this inhibition increased significantly when plant residues were added to the Egyptian clover variety at concentrations of 3 and 6grams, achieving inhibition in the germination of barley seeds.
