Previous works on deep learning architectures like ResNet and DenseNet exhibit promising efficiency in DR detection. However, they're typically computationally expensive and sluggish, rendering them relatively unsuitable for real-time scientific purposes. Also, there are challenges associated with the existing models of displaying normality and the normal distributions to enhance hyperparameters, which often result in the models' generally poor performance. To lower the version complexity and maintain higher accuracy in low-light situations, this examines the cost of the significant GhostNet structure with the former high-throughput ResNeXt model to establish Ghost-ResNeXt. To improve the model performance even more, we propose a new algorithm called Locust-Inspired Optimization, which belongs to swarm intelligence inspired by biological processes. These rules pleasantly tune the model's hyperparameters by emulating the swarm behavior of locusts for the best feature selection and classification. The proposed method entailed training the Ghost-ResNeXt model on a large data set of retinal images. At the same time, the parameters were optimized with the aid of a locust-inspired optimization algorithm. The model design prevents intricate patterns of DR from overshadowing the computational burden while optimally retaining valuable diagnostic information. Experimental outcomes proved that the Ghost-ResNeXT is superior to the conventional architectures in terms of accuracy and pace, which resulted in a remarkable improvement in DR detection accuracy within a comparatively reduced range of parameters. The Locust-Inspired Optimization enhances model stability, achieving higher precision and recall than conventional optimization techniques.

The penta hybrid nanofluid consists of blood as the base fluid and five different nanoparticles of Al₂O₃, ZrO₂, Fe₃O₄, Ag and MoS₂. The main goal of this study is to examine the laminar, time-dependent, and incompressible flow of a penta-hybrid nanofluid under the influence of a magnetic field, focusing on the squeezing flow of a Boger micropolar nanofluid between both porous and non-porous disks, while also analyzing its thermal properties. The fluid is subjected to squeezing at the top disk, which is in motion in the axial direction, and a uniform suction/injection at the bottom disk. Energy and velocity slip effects are also considered at the fixed bottom disk. For the analysis of the flow, appropriate similarity transformations are utilized to reduce the governing partial differential equations (PDEs) to nonlinear ordinary differential equations (ODEs), which are then solved numerically using Python. The analysis demonstrates that an increase in the solvent fraction factor (<em>β</em>₁) improves the heat transfer and flow velocity, and higher values of the relaxation time ratio (<em>β</em>₂) decrease the thermal conductivity. Also, an increase in the magnetic parameter (M) and microrotation (K) increases the resistance to flow and decreases the heat transfer efficiency.
