Nōṭṭusvara are a novel compositional form in Carnatic classical music that emerged in the colonial period in south India, where vernacular lyrics were set to the popular Celtic/Baroque melodies. Muttuswāmi Dīkṣitar is attributed for the creation of the genre of Nōṭṭusvara. The present study questions the very intent of the conception of these specific compositions by Dīkṣitar, and explores beyond the conventional idea of him composing these pieces due to his exposure to the band music in Madras.

Folding and unfolding of proteins is a biologically important topic as many neurological diseases involve misfolding of proteins. Here we have used the technique of X-ray crystallography to characterise the early stages of unfolding of the protein lysozyme purified from hen egg-white. The results when compared with our earlier studies reveal, for the first-time, the possibility of protein unfolding to start from a unique point. If true, this would enable engineering of proteins and drugs to prevent neurological disorders.

 In this study, a modular radial flow annular reactor using the strontium bromide hexahydrate-monohydrate conversion reaction is designed for long-term energy storage, and performance analysis is conducted for eight cities from the Indian Himalayan Region, each with distinct meteorological characteristics, to evaluate the system’s suitability.  The year-long charging and discharging efficiencies are nearly location-independent, with consistent values of ∼35 % and ∼74 %, respectively.

Anthropogenic greenhouse gas emissions significantly impact the middle and upper atmosphere. They cause cooling and thermal shrinking and affect the atmospheric structure. Atmospheric contraction results in changes in key atmospheric features, such as the stratopause height or the peak ionospheric electron density, and also results in reduced thermosphere density. These changes can impact, among others, the lifespan of objects in low Earth orbit, refraction of radio communication and GPS signals, and the peak altitudes of meteoroids entering the Earth's atmosphere.

This study explores the realm of chaotic dynamics, Neurochaos Learning (a brain-inspired machine learning paradigm) and Normal numbers, focusing on the introduction of a novel chaotic trajectory termed the Universal Orbit. The study investigates the characteristics and generation of universal orbits within two prominent chaotic maps: the Decimal Shift Map and the Gauss Map. It explores the set of points capable of forming such orbits, revealing connections with normal numbers and continued fractions.
