Installation of a multifrequency Global Navigation Satellite System at Krea Campus

On 25 and 26 September 2025 Krea University successfully installed a multifrequency Global Navigation Satellite System receiver at the Sri City campus. The instrument is a calibrated state of the art GNSS receiver which can be operated as a reference system. This will be measuring multiple L-band radio frequencies emitted by different global satellite based positioning and timing systems such as GPS, GLONASS, Galileo, Beidou, NAVIC and QZSS. From the measurements, total electron content of the ionosphere can be estimated as a routine 24/7 data product.

This will boost the ongoing space research activities in Krea University and also at a regional level in the Indian longitude sector. The data will be immensely helpful to study the low latitude ionospheric disturbances that affect radio communications and navigation capabilities. The instrument is purchased from the financial support of ANRF through Early career grant to Dr Lakshmi Narayanan, Assistant Professor, Environmental Studies, SIAS.

Dr Shriddha Shah speaks at the HRSC Talk Series at IIIT Hyderabad

Dr Shriddha Shah, Assistant Professor of Philosophy, SIAS delivered a talk on ‘Animal Laborans to Homo Faber: Rethinking Labour and Work Through Arendt and Marx’ at Human Sciences Research Centre, IIIT, Hyderabad​ on 1 October 2025.

About the Talk

The concept of labour with its various implications is central to the structuring of the modern political economy. It is also the cornerstone of Karl Marx’s assessment of the capitalist political economy. Hannah Arendt, in The Human Condition, offers a critique of Marx’s thesis on labour, and thereby his ensuing assessment of society and politics. This paper argues that there is a significant change in the conceptualisation of labour, as discussed by Hannah Arendt, particularly in her examination of the distinction between the concepts of labour and work.

Marx in his thesis makes no distinction between work and labour. However, for Arendt the lack of this distinction is a critical component of her criticism of Marx’s thesis on labour. This paper addresses this issue and argues that Arendt’s thesis rests on presuppositions of metaphysical and methodological dualism, in contrast to those of Marx, and the changed conception of labour is not contingent or a matter of oversight but is based on commitments to different points of view. The paper further argues that this change also influences subsequent formulations of labour and its issues, in contemporary assessments of the political economy.

SIAS Students and Faculty publish a research paper

SIAS students Aishani Tewari, Gayatri Tendulkar, and SIAS faculty members Professor S Sivakumar, Dean – Research and Professor, Physics and Dr Kalyan Chakrabarti, Associate Dean (Students) and Associate Professor, Biological Sciences and Chemistry along with Apurva Phale and Ranabir Das from National Center for Biological Sciences, Bangalore have published a paper titled, Analyzing sub-millisecond timescale protein dynamics using eCPMG experiments. The team has designed experiments to measure fast motion in proteins.

How to measure protein motion at 50,000 per second or faster? How much information can we get from the measurements? Extreme Carr-Purcell-Meiboom-Gill (eCPMG) experiments can provide such information, but there are practical considerations. The team has designed a safe and practical measurement scheme. The knowledge of the motion of protein molecules might provide clues about a wide range of diseases, from Cancer to Alzheimer’s.

Dr Dhanya Radhakrishnan and Dr Venkata Srinu Bhadram, Assistant Professor of Physics publish a collaborative paper in Journal of Applied Physics

Dr Dhanya Radhakrishnan, Lab Manager, Physics and Chemistry Labs and Dr Venkata Srinu Bhadram, Assistant Professor of Physics, SIAS have published a collaborative paper titled High-pressure structural stability of compositionally complex pyrochlore oxides in Journal of Applied Physics. It’s a collaborative work involving researchers at IIT Madras, Elettra (Italy), and Vinca Institute of Nuclear Sciences (Serbia). In this work, ​t​he researchers complex oxide ceramics remain structurally stable under extreme pressures of up to 20 gigapascals. This remarkable stability makes it promising for applications in harsh environments, such as nuclear waste immobilization, high-performance fuel cells, and heat-resistant coatings.

​Dr Vivek Tewary presents at the GANIT symposium at IIT Gandhinagar

Dr Vivek Tewary, Assistant Professor, Mathematics, SIAS, presented a talk on ‘Regularity Theory for Nonlocal p-Laplace Equations’, at the GANIT symposium on ‘Stochastic Processes and Related Topics 2025’, at IIT Gandhinagar from 13-15 September 2025.

About the talk: Brownian motion is related to the Laplace operator as jump Levy processes are related to the nonlocal Laplace operator. Similarly, the p-Laplace operator has a probabilistic interpretation in a tug-of-war game with noise and the nonlocal p-Laplace operator comes from a nonlocal version of this tug-of-war game. A recent turn is to study these operators using non-probabilistic methods. While the probabilistic interpretations are linked to non-divergence type operators, in this talk, they focussed on one of their divergence type counterparts. In particular, they discuss the local boundedness and local Holder regularity of solutions of the parabolic divergence type nonlocal p-Laplace equation.

About the workshop: The aim of this meet is to bring together researchers in the country working on stochastic processes and related areas (such as partial differential equations, dynamical systems) for a series of stimulating lectures and discussions. It is hoped that this can be the first meet in an annual tradition and provide a forum for explorations of new ideas and forging of new collaborations.
