Exploring mathematics from a literary perspective
A paper by Prof. Arka Chattopadhyay of IITGN makes us think about the social and political significance of numbers and counting in everyday life. To think about number in our social life, let us consider everyday operations like OTP or the number of likes on social media. Prof Chattopadhyay’s work explores J. M. Coetzee's novel, The Schooldays of Jesus (2016), which presents a mythology of numbers as stars and imagines dance as a way of invoking these numbers. The study is a step towards thinking numbers as an idea that goes beyond calculation and shows how processing numbers can evoke feelings. For example, we could think of numbers and anxiety the way we would look at Covid numbers everyday on the news, during the pandemic.

Tuning cable-driven manipulator’s stiffness to enable human-robot interaction tasks
Manipulators with serial chain architectures are being widely used by the robotics community owing to their unique properties like high repeatability, large workspace, and ease of control. Over the years, cable-driven serial-chain manipulators (CDSMs), where motor actuated cables apply external forces on links to control the end-effector motion, have emerged as an important robotic platform. Among the various performance measures of a manipulator, stiffness is a critical characteristic as it regulates its rigidity, positioning, and trajectory tracking accuracy during a physical interaction task. An IITGN-led work provides insight into the ability of a CDSM to tune stiffness for human-robot interaction tasks.

How electrodialysis can outperform reverse osmosis for desalination
Electrodialysis (ED) is a water treatment process that uses ion-exchange membranes and an applied electric field to remove salts and charged organic matter. Though ED is commercially available, Reverse Osmosis (RO) dominates the water desalination and purification market. However, the academic literature has shown that ED is energetically favorable to use for lower salinity feed solutions compared to RO. IITGN researchers draw an analogy between ED and RO to clearly identify the conditions under which ED is economically favorable compared to RO for desalination, in terms of the cost of pure water production.

How DNA nanostructures’ geometries influence their biological interactions
Nanostructures made of synthetic DNA have been used for drug delivery, and in diagnostic and therapeutic applications. Cellular delivery of such nanostructures is highly desirable as they must be efficiently taken up by the cells to perform the required function. Although DNA nanotechnology has spawned nanostructures with varied shapes and sizes to be used as cells’ delivery vehicles, significantly fewer studies have addressed the influence of shape, size, and cell type in their cellular uptake process.

Metal-boride-derived nanosheets could be next-generation photocatalysts for hydrogen evolution
A collaborative research work carried out at IITGN has showcased the rich potential of nanosheets derived from metal borides as true photocatalysts towards hydrogen evolution. The team has created a facile scheme wherein, Hydrogen (H2) evolution can be achieved within a test tube laced with a nano-catalyst by simply placing it in front of a light source. The production of H2 was viable even with power as low as that of half of the sun’s power. In the study published in the International Journal of Hydrogen Energy, the team reports that the catalyst concoction comprising the nanosheets and gold nanoprisms in precise amounts, can even produce H2 under Ultraviolet and Near-Infrared irradiation. Moreover, this catalyst can produce similar results when only exposed to natural sunlight. The experimental conditions designed by the researchers are mild and relatively less energy intensive. The team believes that the method could have promising commercialization prospects and thereby make a positive impact on the energy requirements of the country.

Creating 3D shadow art sculptures using differential rendering
The shadow works like ‘Sunset over Manhattan’ and the ‘Wild Mood Swings’ are indeed astounding enough to leave us wonderstruck. This art of casting beautiful shadows of objects under proper lighting is called shadow art. It is a unique form of sculptural art where 2D shadows cast by a 3D sculpture produce artistic effect. Researchers at IITGN introduce a method to create 3D shadow art sculptures that cast different shadows when lit from different directions. For this, they used an optimisation framework called differentiable rendering, which is used for 3D reconstruction. The generated complex 3D sculptures go beyond those seen in contemporary art pieces. What’s more interesting is that through this method, they have obtained the 3D sculpture solely from a set of 2D shadow images and their corresponding projection information, thus, eliminating the need for any 3D data collection and annotation.

Investigating the role of a key modulator protein in Alzheimer’s disease
AD, a common neurodegenerative disorder and a leading cause of dementia, is characterized by the accumulation of amyloid beta (Aβ) peptides. In the AD-associated pathway, an enzyme called β-secretase initiates cleavage of amyloid precursor protein (APP), which is an integral membrane protein, to generate a particular fragment (C-99) of APP. This fragment is further cleaved by γ-secretase enzyme to generate the Aβ. Previous studies report that the inhibition of a large protein complex called Gamma (γ)-Secretase activating protein (GSAP) reduces the deposition of Aβ plaques in brain tissue points, thus making it a promising therapeutic target in the treatment of AD. However, this novel protein has not been studied extensively and its interaction with APP C-99 has not been sufficiently examined. This IITGN-led work identifies and maps the interaction region of GSAP and APP C-99 in the AD-associated pathway. The team employed a range of molecular biology, biophysical and biochemical approaches to explain the domain-specific affinity of GSAP towards APP C-99. By determining this protein-peptide interaction, they establish a crucial and previously undefined mechanism of action for GSAP trafficking within the AD-associated pathway.

Impact of disasters on the marginalised communities of the Sunderbans
Marginalised groups are identified as highly vulnerable populations largely deprived of social, educational, and economic opportunities. This research argues that the Sunderbans’ socially disadvantaged groups are experiencing a similar process of marginalisation whereby they are pushed into vulnerable ecological spaces and hold economically inferior societal positions. They majorly depend on the limited mangrove forest resources for livelihood, which puts them in regular contact with tigers and other wild animals. The team also found that alongside local communities, even tigers and mangrove species are marginalised because the trio co-inhabit the same vulnerable and contested site, leading to layered interactions between them for limited resources and spaces, especially when exposed to the risk of frequent cyclonic devastations. The project seeks to initiate a community radio setup by collaborating with local stakeholders like NGOs and village panchayats for its outreach program.

Understanding biases in the news media reporting on air pollution
According to the research team led by Prof Nipun Batra of IITGN, theirs is the most extended study, to date, of air pollution-based news articles with 190 Indian cities analysed. They curated a dataset of 17.4k news articles on air pollution from two leading English daily newspapers spanning 11 years (2010-2021). The team’s analysis revealed that although air pollution is a year-long problem in India, the news media’s interest in the issue is periodic, indicating temporal bias. The issue is discussed only when the effect is high and visible as smog during winter. In addition, #geographical bias is observed as the media pays more attention to the #MetropolitanCities rather than the cities in the Indo-Gangetic plane, which are highly polluted. Moreover, the Indian news media focuses on quickly visible sources like #VehicularEmissions and open burning, while they miss reporting about household sources that significantly contribute to air pollution.

Novel molecules to illuminate cell's largest organelle in cancer and non-cancerous cells
The endoplasmic reticulum (ER), the largest organelle in the eukaryotic cells, is responsible for serving myriads of cellular functions. The ER plays an important role in protein biosynthesis and regulates protein processing through post-translational modifications, which, if disrupted, leads to stress accumulation (ER stress) inside the cells.

Do smaller governments cater more for their citizens?
One of the fundamental functions of government is to provide public goods to its citizens. Now the question arises, do smaller local governments do it better? A study conducted by Prof Deepak Singhania of IITGN answers this question by showing that smaller local governments, when also held accountable, provide more for their citizens.

Towards securing the data exchanged through modern applications
Researchers present a verified implementation of protocols that form the basis of applications like WhatsApp and WireGuard. This guarantees the non-existence of security bugs, which in turn, would protect the data being exchanged through these applications. Modern applications rely on a variety of secure channel protocols. Noise protocol is a framework that can be used to construct secure channel protocols, some of which are used in popular applications such as WhatsApp and WireGuard. The specifications and implementations of these protocols, however, may be bug-prone and have security issues that may leak secret data to adversaries. Prof Abhishek Bichhawat, Assistant Professor, Computer Science and Engineering at IITGN, in collaboration with researchers from Inventeurs Du Monde Numérique (INRIA) and Microsoft Research, has presented the first verified implementation of the Noise protocol framework.

The discovery of shell midden provides insights into the prehistory of the Khadir Island
The UNESCO World Heritage Harappan site of Dholavira is located on Khadir Island in the Great Rann of Kachchh. An IITGN-led team recently investigated the past climate stages of this island in relation to the site. The study has led to the discovery of a shell midden site, 17 km southeast of Dholavira near village #Bambhanka. A shell midden is an archaeological site composed of heaps of remains of shell-bearing animals. It provides valuable information about the diets and habits of past societies. The discovery will enable a better understanding of the prehistory of Khadir, now datable to around the 6th millennium BP, before the emergence of settled human life. Moreover, the updated information can be used by the education department and tourism industry.

New model to analyse the effect of natural disasters on transportation systems
An IITGN research team led by Prof Udit Bhatia has developed a framework to study the effect of concurrent hazards, like #floods, #landslides, and #debris flow on transportation systems. Their integrated predictive model can accurately understand and assess the real magnitude of heavy rainfall-induced damages in regional road networks. Enhancing resilience requires an understanding of the risk for pre-disaster preparedness and post-disaster recovery. This hazard model along with the team’s patented complex network framework can help administrators identify the ‘hotspots’ which should be reinforced and protected to solve highway-flooding issues and minimise the socio-economic disruptions.

A robot that learns movements on its own
Humans can learn to perform new tasks by repeated trials (practice), and they can also learn to adapt to environmental perturbations in movement tasks they have already learnt. For most tasks, humans can do this with no supervision or coaching. An IITGN research team led by Prof Harish Palanthandalam-Madapusi aims to bring similar functionality to robots. The robot learning in the video (https://bit.ly/3LGOJQj) is one of their early successes in bringing self-learning by trial-by-trial practice (both for learning to move along new trajectories and to adapt to environmental perturbations).

Towards improving predictions of future sea-level rise and their rates along the Northern Indian Ocean
With increasing global temperatures, the world grapples with the challenge of rising sea levels that is a threat to low-lying coastal communities and infrastructure. It is thus crucial to accurately understand the mechanisms and their contribution towards the ongoing sea-level rise. Coral reefs, the shallow-marine habitats, have been extensively used as paleo/past sea-level records because coral reefs live within strict ecological requirements. Hence, they provide an opportunity to examine sea-level fluctuations and reef growth rates on various time scales.

Probing into the expressivity of non-human bodies
Prof Angus McBlane, Visiting Assistant Professor at Humanities and Social Sciences, IITGN, is working on a project that focuses on experiential, embodied, and lived aspects in posthumanism. Posthumanism emerges from the idea that humans are not set above the world nor entirely distinct from non-human animals, objects, and concepts. The work could promote a different way of thinking about bodies, the world, and our relationship with others within it.

New approach opens the door to large-scale hydrogen production
Prof Nitin Padhiyar of IITGN along with a former MTech graduate, Md Zafar Ahmed, conducted the first-ever comparative study of the optimal operation of tubular and spherical reactors, on the basis of the power loss due to pressure drop. The three objective functions of the optimisation approach include maximisation of hydrogen production, minimisation of carbon dioxide emission, and minimisation of power loss due to pressure drop. The results show that the spherical reactor has the edge over the tubular reactor in terms of low power loss and therefore more #energy savings. Their reactor design approach meets the important aspects, like #environment #pollution, cost, and productivity and can be used to design other similar processes in fixed bed reactors.

Certain geometric aspects of number theory
A derivative operator is an important tool that has led to modern-day calculus. It often allows us to approximate complicated functions with simpler ones. In the case of numbers, an analogue of differentiation is given by p-derivations. This enables us to ‘approximate arbitrary numbers’ with respect to a fixed prime number p. Prof Arnab Saha of IITGN and Prof Debargha Banerjee of IISER Pune look into the geometry of spaces that naturally arise from such p-derivations and modular forms.

Investigating structural effects of a protein associated with neurological disorders
Dr Lata Rani and Prof Sairam S Mallajosyula of IITGN has conducted one of the first theoretical studies to describe the influence of PTMs on the PHF structure of Tau protein. They investigated the impact of phosphorylation and O-GlcNAcylation, a type of #glycosylation, on the conformation of tau PHFs at experimentally verified PTM sites. The researchers found that the structural effects upon PTMs were prominent for phosphorylation compared with those for O-GlcNAcylation. The study’s results would be insightful for further drug-discovery endeavors.

Unearthing the occurrence of mineral deposits at the Harappan sites of Gujarat
The archaeologists at IITGN embark on the study to understand the occurrence of some raw materials from the Harappan sites in Gujarat. The present study builds upon the past mineralogical investigations that reveal the occurrence of raw materials like agates and ores. It also finds new information on the occurrence of ochre, a natural clay earth pigment, within the Khadir island on which Dholavira is situated. The IITGN-led team also found that the ‘Ernestite’ nodule from Bhagatrav (south Gujarat) exhibited similar mineral structure from other Harappan sites, indicating its use in bead drilling, even in rural settlements. The Harappans mastered the use of ernestite, a hard rock, for producing drill bits to perforate beads, and exported to distant locations in Mesopotamia (modern Iraq). The team includes Ravi Kant Prasad, post-doctoral fellow and Prof V N Prabhakar, Associate Professor, Humanities and Social Sciences, IITGN.

Simple method to prepare free-standing metal films of high index orientation
An IITGN research team came up with a simple yet cost-effective way to fabricate free-standing single-crystal films of metals. This is done by depositing metal vapour on a carefully-prepared surface of rock salt. Compared to previous work, this approach not only allows one to grow single crystals but also choose the orientation of the crystal from a list of possibilities including some difficult to achieve high index orientations.

New and engaging paradigm to access dual-tasking in individuals
Prof Vineet Vashista at the Human-Centered Robotics Lab, IITGN, along with his PhD student, Yogesh Singh, conducted studies that focused on the dual-motor-task paradigm. This is the first-ever study wherein they used a virtual reality system to construct and project the experimental conditions. The team designed a dual-motor-task paradigm wherein the 24 healthy subjects catch and throw a ball (secondary task) in the virtual environment while walking (primary task) over ground. The participants walked conservatively during dual-tasking. However, the secondary task objective was met significantly better in dual-task than in single-task.

Balance is hard, even in theory
For computer scientists, solving the puzzle of imbalance in general is an example of what they call a “hard problem”. So if you could come up with an algorithm that can find the optimal ordering for any network of friends very efficiently, then that would have surprising consequences! Nonetheless, it’s a problem we want to solve, for fun and profit, given that the notion of imbalance has varied applications (for instance, in graph drawing). The work of IITGN researchers, Harshil Mittal and Prof Neeldhara Misra, involves designing an algorithm to compute imbalance-optimising layouts for friendship networks with a certain special structure – roughly speaking, ones that are generally very friendly except for a small number of people.

Quantum Statistics can lead to Enhanced Thermal Machines
Prof Prasanna Venkatesh of IIT Gandhinagar along with his collaborators considered an ensemble of indistinguishable quantum machines to show that quantum statistical effects can cause a genuine quantum enhancement of the collective thermodynamic performance. Typically, it is assumed that multiple thermal machines produce an additive effect in terms of output. However, the team has shown that the collective effects present when the machines are indistinguishable Bosonic systems leads to enhanced performance. This effect suggests that it may be possible to design better thermodynamic devices in the future by exploiting quantum statistics.

Novel approach towards developing a digital signal processor
Prof Nithin George of IITGN and his team has utilised the concepts of distributed arithmetic, probability theory, and approximate computing to propose a novel approach for efficient realisation of inner-product architectures. The proposed designs consume nearly 40% less area and 41% less energy in 45nm CMOS (Complementary Metal-Oxide-Semiconductor) technology, used for constructing integrated circuits, with 25% less error than the existing structures. This work is a critical step towards developing a low-power digital signal processor, one of the fundamental constituents of an assistive listening device.

Analytical study to explore regions of instability in bi-linear Mathieu equation
Piecewise linear oscillators are essentially nonlinear. Though they are seemingly uncommon, there are many engineering systems that exhibit piecewise linearity. For example, gear pairs with periodic stiffness and backlash, structural beams with breathing cracks, asymmetric stiffness in tension and compression in structures, etc. Analytical study of such dynamical systems is not readily amenable to well-known analytical/asymptotic techniques. Prof K R Jayaprakash, Assistant Professor, Mechanical Engineering, IITGN and Prof Yuli Starosvetsky, Associate Professor, Faculty of Mechanical Engineering, Technion, Israel, conducted a study to devise analytical approaches to explore the regions of instability in piecewise linear Mathieu equation.

Fast and Efficient Model for estimation of peak-current
Prof Ragavan K at IITGN, along with Amarkumar Kushwaha (PhD student) from IIT Bombay, has proposed a fast approach to achieve this. The proposed model is an alternative to time-consuming dynamic simulation models for steady-state peak current estimation. It is expected to be fast and efficient for the estimation of the peak-current magnitude. This model can be used as the first step for the selection of switches while designing the power converter of the SRG. It can further be modified into a torque estimator, and hence, can be integrated in the optimisation routine because of faster computation.

Wildlife Conservation: A social process on a daily basis
Prof Ambika Aiyadurai of IITGN and Sayan Banerjee, PhD Scholar at the National Institute of Advanced Studies, Bengaluru, India, analysed a typical Asian elephant conservation project in Assam, India. Unlike the existing studies on community-based wildlife conservation in India, this study demonstrates conservation to be a social process in which actors such as the local community, NGO-based project managers and staff, government agencies, and international donor agencies, interact and thus, collaborate or engage into conflict.

A Nice Geometric Structure for Certain Quiver Representations
In mathematics, a quiver is a directed graph (graph made up of a set of vertices connected by directed edges) possibly with multiple loops and arrows between two vertices. A representation of a quiver assigns a vector space to each vertex and a linear map to each arrow. Quivers and their representations have been an active area of research for many years and have applications in many other branches of mathematics such as #algebra, Lie theory, algebraic #geometry, and #physics.

Caste, Ethnicity and Middle-class Politics in Colonial India: A Case study from Assam
Prof Madhumita Sengupta’s research revolves around questions of caste, class, and ethnicity in colonial India. One of her recent publications argues that Assamese literary representations of the European planter (tea estate manager) during the colonial regime drew a veil over the dark side of plantation abuses. The authors analyse the Assamese short story, ‘Chameli Memsaab’, written by Nirode Chaudhury, describing the intimate relationship between a European Planter sahib and a woman plantation worker (coolie). The paper foregrounds the apathy of the Assamese middle class towards the plantation workers distanced from the former by virtue of caste and ethnicity.

Why RO outperforms other technologies for desalination?
You may have heard that desalination, the process of obtaining freshwater by removing salts and minerals from saline water, is quite energy-intensive. The cost of energy can contribute to approximately 25–40% of the total cost of water. Various technologies, powered by different kinds of energy input have been developed. Reverse Osmosis (RO) and Multiple-Effect Distillation (MED) are two major desalination technologies. While RO purifies water through membrane pores, MED uses heat to evaporate and then condense pure water.

How do genes “jump”?
Mobile genetic elements or transposable elements can jump from one place to another in the genome (complete genetic information in an organism), aided by transposase proteins. They constitute large portions of most genomes and have profound effects on gene expression, genome evolution and disease. THAP9, a newly discovered human gene, has significant sequence similarity with an active transposase protein found in fruit flies. The exact cellular function and physiological role of THAP9 is unknown. And we still don’t know if it can jump in the human genome!
