This study discusses a methodological framework in conjunction with the existing probability-based risk metrics for assessing the resource adequacy of the electricity generation mix, considering the generation capacities of different sources, their average availability levels, and the possible outages that these sources may suffer from. The simulations show that the available capacity decreases with an increasing number of discrete risk events, which limits the capability of the power system to meet the demand.

The Social Internet of Things (SIoT) enables collaborative service provisioning among interconnected devices by leveraging socially inspired trust relationships. This paper proposes a socially driven SIoT protocol for trust-aware service selection, enabling dynamic friendship formation and ranking among distributed service-providing devices based on observed execution behaviour.

• Shallow lakes in the sub-tropics are more prone to eutrophication and cyanotoxin pollution.
• Microcystin-LR is a commonly occurring cyanotoxin in water bodies and a potent toxin for living organisms.
• MC-LR depends on harmful algal blooms (HABs), trophic state index (TSI), and bio physicochemical variables of water bodies.
• Ecohydrological monitoring and epidemiological interventions will help in the systematic remediation of cyanotoxin pollution

This paper examines the impact of environmental change on traditional ironworking societies in the Chotanagpur Plateau, in Eastern India, particularly in Purulia (West Bengal) and Hazaribagh and Chatra (Jharkhand). Part of the Iron Belt due to the rich mineral resources,  traditionally these regions were home to communities of indigenous iron smelters and blacksmiths such as the Asur, Lohra, Karmakar, and Karmali.

The study describes a new species of Polyrhachis, or spiny ant, named Polyrhachis garbhangaensis sp. nov., from the state of Assam, northeastern India. This species was collected and identified during field sampling in the Garbhanga Reserve Forest, near the city of Guwahati in Assam. It represents a third Indian species of the P. mucronata species group in the subgenus Myrmhopla. Polyrhachis Smith, 1857 is a genus of ants, found widely across the Old-World tropics, with significant diversity across Southeast Asia.

Sacred architecture across cultures has often been aligned with celestial events such as solstices, equinoxes, and significant stellar risings. This study reviews global traditions of astronomical alignment and the techniques ancient builders may have used to achieve such precision, alongside contemporary methods including satellite imagery, field surveys, and astronomical simulations. Focusing on temple architecture in South India, it employs geospatial tools and simulation software to analyze orientations in relation to solar, lunar, and stellar phenomena.

Geospatial technologies have transformed cultural heritage research by enabling the analysis, visualization, and interpretation of historical landscapes. They support scholars in reconstructing past geographies, mapping site distributions, identifying hidden archaeological features, and informing heritage management strategies. Spatial Narratives of India’s Heritage: Geospatial Analysis in the Humanities showcases how GIS, remote sensing, and spatial analysis enrich multidisciplinary research on India’s past.

Mysorean rockets were an important technological innovation in eighteenth-century warfare, developed under the leadership of Hyder Ali and Tipu Sultan. They were among the earliest iron-cased rockets used in battle and had a significant impact on military tactics of the time. This study examines the role of Mysorean rockets in eighteenth-century warfare under Hyder Ali and Tipu Sultan, with a focus on their tactical deployment and innovative use in battles.
