Spatial attention U-Net model with Harris hawks optimization for retinal blood vessel and optic disc segmentation in fundus images.

Background: The state of the human eye's blood vessels is a crucial aspect in the diagnosis of ophthalmological illnesses. For many computer-aided diagnostic systems, precise retinal vessel segmentation is an essential job. However, it remains a difficult task due to the intricate vascular system of the eye.

Brain disorders: Impact of mild SARS-CoV-2 may shrink several parts of the brain.

Coronavirus (COVID-19) is a highly infectious respiratory infection discovered in Wuhan, China, in December 2019. As a result of the pandemic, several individuals have experienced life-threatening diseases, the loss of loved ones, lockdowns, isolation, an increase in unemployment, and household conflict. Moreover, COVID-19 may cause direct brain injury via encephalopathy.

Hydrothermal synthesis of novel heterostructured Ag/TiO /CuFe O nanocomposite: Characterization, enhanced photocatalytic degradation of methylene blue dye, and efficient antibacterial studies.

In this work, we reported the successful synthesis of novel Ag/TiO /CuFe O ternary nanocomposite by hydrothermal technique by using TiO /CuFe O binary nanocomposite precursor that was also prepared by hydrothermal treatment by using TiO nanoparticles and CuFe O nanoparticles synthesized via sol-gel method. The synthesized nanomaterials were accessed for their morphological, structural, and optical properties. X-ray diffraction (XRD) study reveals the formation of pure Ag/TiO /CuFe O ternary nanocomposite in which the Ag, TiO , and CuFe O are in anatase, spinal, and cubic crystal phases, respectively.

Microbiomics and cloud-based analytics advance sustainable soil management.

Soil constitutes a major component of the agro-ecosystem. Unrestrained uses of chemical pesticides and increased human activities have contributed to unprecedented changes in soil microflora affecting productivity. Modern microbiomics has proven to be an indispensable tool to understand the adaptations underlying complex soil microbial communities and their beneficial applications.
