A Hybrid Approach for Sports Activity Recognition Using Key Body Descriptors and Hybrid Deep Learning Classifier.

This paper presents an approach for event recognition in sequential images using human body part features and their surrounding context. Key body points were approximated to track and monitor their presence in complex scenarios. Various feature descriptors, including MSER (Maximally Stable Extremal Regions), SURF (Speeded-Up Robust Features), distance transform, and DOF (Degrees of Freedom), were applied to skeleton points, while BRIEF (Binary Robust Independent Elementary Features), HOG (Histogram of Oriented Gradients), FAST (Features from Accelerated Segment Test), and Optical Flow were used on silhouettes or full-body points to capture both geometric and motion-based features.

Unveiling the Malignancy Risk of Surgically Treated Bethesda III Thyroid Nodules: A 10-Year Retrospective Study Comparing Fine-Needle Aspiration Cytology (FNAC) and Histopathology.

Introduction Thyroid malignancy remains a significant global health concern, making the accurate differentiation between benign and malignant thyroid nodules crucial for optimal patient management. Fine-needle aspiration cytology (FNAC) is the gold-standard preoperative diagnostic tool, and The Bethesda System for Reporting Thyroid Cytopathology provides a standardized framework for interpretation. This 10-year retrospective study evaluated the malignancy risk in surgically treated patients with thyroid nodules classified as Bethesda Category III by comparing FNAC findings with histopathological outcomes.

Wireless power-up and readout from a label-free biosensor.

Wearable and implantable biosensors have rapidly entered the fields of health and biomedicine to diagnose diseases and physiological monitoring. The use of wired medical devices causes surgical complications, which can occur when wires break, become infected, generate electrical noise, and are incompatible with implantable applications. In contrast, wireless power transfer is ideal for biosensing applications since it does not necessitate direct connections between measurement tools and sensing systems, enabling remote use of the biosensors.

Bioactive Silk Revolution: Harnessing Curcuminoid Dye and Chitosan for Superior Antimicrobial Defence and UV Shielding.

Background/objectives: The use of natural colourants is gaining attention due to their biocompatibility and functional benefits. This study introduces a different approach using turmeric ( L.) dye extract combined with chitosan to significantly enhance the antibacterial and UV-shielding properties of silk.

One-pot, Four-component Synthesis, Molecular Docking and Pharmacokinetic Studies of Tetra-substituted Imidazole Derivatives as Potential Mushroom Tyrosinase Inhibitors.

Introduction: An efficient and four-component one-pot facile synthesis of tetra-substituted imidazole is achieved by cyclo-condensation reaction of benzil with subsequent successive substitution of aromatic aldehydes, ester substituted amine and ammonium acetate via refluxing the mixture for almost two hours at 140°C.

Method: The ending point of the understudy reaction was examined by TLC after regular intervals. Synthesized 1,2,4-tetrasubstituted imidazoles were characterized by physical data and the structural features were analyzed using spectroscopic techniques such as FTIR, NMR and elemental analysis.
