Background: Radiographs are used extensively in dentistry to supplement the clinical examination of the patients. Technical advances in X-ray equipment and imaging systems have allowed significant reduction in radiation doses of patients during intraoral and extraoral radiography.
Objectives: The aim of this study was to determine the level of awareness of dental professionals of northern India regarding dose-reduction techniques and radiographic equipment.
Methods: The survey covered 370 dentists in the states of Punjab and Haryana in northern India. Information on the demographic characteristics of the dentists, radiographic equipment, techniques, and radiation protection was obtained with a 30-point questionnaire.
Results: The respondents knowledge concerning the technical details of their equipment was limited, with 82.3% not being aware about the kilovoltage peak of their machine. Up to 10.8% dentists were not aware about the speed of film. The most preferred technique for periapical radiography was the bisecting angle technique, which was used by 94.1% dentists.
Conclusion: In the present study the results indicate that for minimizing any unnecessary radiation, attempts should be made to improve dentists' knowledge about radiation-dose-reduction techniques.

In resource-constrained countries like India, mammography-based breast screening is challenging to implement. This state-wide study, funded by the Government of Punjab, evaluated the use of Thermalytix, a low-cost, radiation-free AI tool, for breast cancer screening. Community health workers, trained to raise awareness, mobilized women aged 30 and above for screening.

Semantic segmentation of high-resolution images from remote sensing is crucial across various sectors. However, due to limitations in computational resources and the complexity of network architectures, many sophisticated semantic segmentation models struggle with efficiency in real-world applications, leading to an interest in developing lightweight model like borders. These models often employ a dual-branch structure, which balances processing speed and performance effectively.

Precise estimation of rock petrophysical parameters are seriously important for the reliable computation of hydrocarbon in place in the underground formations. Therefore, accurately estimation rock saturation exponent is necessary in this regard. In this communication, we aim to develop intelligent data-driven models of decision tree, random forest, ensemble learning, adaptive boosting, support vector machine and multilayer perceptron artificial neural network to predict rock saturation exponent parameter in terms of rock absolute permeability, porosity, resistivity index, true resistivity, and water saturation based on acquired 1041 field data.
