Unfolding of hen egg-white lysozyme – is there a unique starting point?

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.

Techno-Economic analysis of solar thermal seasonal thermochemical storage for Indian Himalayan cities

 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.

Science Beyond Borders: International Collaborations in Basic Sciences

International collaboration in basic sciences allows researchers from different countries to pool their expertise, knowledge, and resources. This combined effort tackles complex scientific challenges that might be beyond the intellectual, technical, and financial capabilities of a single nation. It fosters the sharing of data and ideas, accelerates scientific progress and leads to breakthroughs that benefit all of humanity.

Circular male migration, rural-urban linkages and household food security in India

This chapter looks at ways in which male circular migration as a household livelihood strategy affects food access among rural households in India. Circular male labour migration is the dominant form of labour mobility in many parts of India. This migration pattern creates important rural-urban linkages through income transfers and alters within-household gender power relations.

The Need for Better Monitoring of Climate Change in the Middle and Upper Atmosphere

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.

Universal Orbits: Unveiling the Connection between Chaotic Dynamics, Normal Numbers, and Neurochaos Learning.

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.

Random Heterogeneous Neurochaos Learning Architecture for Data Classification

Inspired by the human brain's structure and function, Artificial Neural Networks (ANN) were developed for data classification. However, existing Neural Networks, including Deep Neural Networks, do not mimic the brain's rich structure. They lack key features such as randomness and neuron heterogeneity, which are inherently chaotic in their firing behavior. Neurochaos Learning (NL), a chaos-based neural network, recently employed one-dimensional chaotic maps like Generalized Lüroth Series (GLS) and Logistic map as neurons.
