- Reconceiving the building blocks of the Universe June 2, 2022
The research at the Department of Physics is currently focusing on developing new theoretical frameworks to revamp the fundamental concepts that describe the origin of the universe. Assistant Professor Dr Amit Chakraborty has published a paper titled Revisiting Jet Clustering Algorithms for New Higgs Boson Searches in the Hadronic Final States in the European Physical Journal C, with an Impact Factor of 4.59.
Abstract
Displaced signatures originating from the pair production of a supersymmetric particle, called sneutrino, at the Large Hadron Collider (LHC) are studied. The theoretical model considered in this work is the Next-to-Minimal Supersymmetric Standard Model supplemented with right-handed neutrinos triggering a Type-I seesaw mechanism. The research has shown how such signatures can be established through a heavy Higgs portal when the sneutrinos are decaying to charged leptons and charginos giving rise to further leptons or hadrons. The research also illustrated how the Yukawa parameters of neutrinos can be extracted by measuring the lifetime of the sneutrino from the displaced vertices, thereby characterising the dynamics of the underlying mechanism of neutrino mass generation.
Explanation of the research
The Standard Model of Particle Physics is currently the remarkably successful theory to describe the basic building blocks of the universe and their interactions with the three fundamental forces of nature. Despite its success at explaining the universe, the Standard Model does have several limitations. For example, how neutrinos get their mass, why the mass spectrum of the different elements of SM fermions, namely quarks and leptons, are so hierarchical, why the Higgs boson mass is so low, etc. The primary research is to understand these issues and then propose theoretical models which circumvent these shortcomings of SM and provide signatures that can be tested in the ongoing or future proposed experiments.
For this research project, Dr Amit Chakraborty have collaborated with Particle Physics Department, STFC Rutherford Appleton Laboratory, UK and School of Physics and Astronomy, University of Southampton, UK. His broad research interest is to perform theoretical studies of physics beyond the Standard Model (BSM) in particular, collider search strategies and prospects of different BSM models at the Large Hadron Collider (LHC) and future proposed collider experiments. He aims to build new theoretical models, develop new techniques/tools, and devise new search strategies to improve our knowledge of the standard model as well as BSM physics processes.
Dr Amit Chakraborty’s future research topics include Higgs Boson Physics and Beyond Standard Model Physics Phenomenology, Dark Matter at the Colliders, Interpretable Machine Learning techniques in BSM Physics, and Ultra-light particles and Physics Beyond the Colliders.

- Hatchlab incubates student venture Amruthik Private Ltd June 1, 2022
Empowering and Enabling startup entrepreneurs
A personal incident motivated Jithin Peram, final year Computer Science Engineering student, to start Amruthik Pvt. Ltd, a company which supplies customised food to various hospitals based on the specific needs of the patients. Various doctors and hospitals have appreciated this customisation of food as per the need. Patients are satisfied as they do not have to take the generic food given by the hospital canteen now. Instead, they have the option to have a very specific diet prescribed by certified dieticians.
The motivation behind the launch of Amruthik is quite inspirational. Jithin’s grandfather passed away due to corona. While his grandfather was suffering with Covid-19 and was admitted in hospital, Jithin was preparing for viva practicals. On hearing the news, he was shattered and it struck him how quickly everything can change around us. Since Jithin was not able to do small things such as taking lunch to his grandfather or standing next to him for moral support; With Amruthik, Jithin dreams of being there for people who need moral support and care in their hospital beds “This makes me happy, and I believe this kind of support is something everyone deserves”, says Jithin on a happy note.
Five years from now, Jithin envisions himself supporting, helping and standing by millions of people who need such services. He believes in putting smiles on faces and wants to see the impressive growth of his company.
Let’s see what Jithin says
As an engineering student, I would have never known the opportunities I have, even with the idea to build my company I would have been lost without proper guidance The Hatchlab Research Centre has given me guidance and a foundation that I can rely upon building my company.
I am thankful for the immense support I got from the faculty and the guidance provided by SRM AP, I especially thank Mr Udayan Bakshi for mentoring me and sharing his experiences with me.

Cesium lead halide perovskite nanocrystals (PNCs) belong to the flourishing research area in the field of photovoltaic and optoelectronic applications because of their excellent optical and electronic properties. Mainly, Cesium lead bromide (CsPbBr3) NCs with bright green photoluminescence (PL) and narrow full-width at half-maximum (FWHM) of <25 nm are the most desirable for television displays and green-emitting LEDs. However, challenges with respect to CsPbBr3 PNCs‘ stability, limit their usage in practical applications. The recent findings of Dr Nimai Mishra and his research team assert that surface passivation with an additional ligand could be an excellent, easy, and facile approach to enhancing the photoluminescence and stability of PNCs.
Dr Nimai Mishra, Assistant Professor, Department of Chemistry, along with his research group comprising of students pursuing PhD under him, Dr V G Vasavi Dutt, Mr Syed Akhil, Mr Rahul Singh, and Mr Manoj Palabathuni have published their research article titled “Year-Long Stability and Near-Unity Photoluminescence Quantum Yield of CsPbBr3 Perovskite Nanocrystals by Benzoic Acid Post-treatment“ in The Journal of Physical Chemistry C (A Q1 journal published by ‘The American Chemical Society’) having an impact factor of ~4.2.
In this article, the research group addresses the stability issues of green-emitting CsPbBr3 PNCs with simple post-treatment using benzoic acid (BA). A remarkable improvement in PLQY from 69.8% to 97% (near unity) was observed in benzoic acid-treated CsPbBr3 PNCs. The effective surface passivation by benzoic acid is also apparent from PL decay profiles of BA-CsPbBr3 PNCs. The long-term ambient stability and stability against ethanol of BA-CsPbBr3 PNCs are also well presented in the research. The PL intensity of untreated CsPbBr3 PNCs is completely lost within five months since the synthesis date, while ̴ 65% of initial PL intensity is preserved for BA-CsPbBr3 PNCs even after one year.
Furthermore, BA-CsPbBr3 PNCs exhibits excellent photo-stability where 36% of PL is retained while PL is completely quenched when the PNCs are exposed to 24 hours of continuous UV irradiation. Importantly, BA-CsPbBr3 PNCs show excellent stability against ethanol treatment as well. Finally, green, emitting diodes using BA-CsPbBr3 PNCs are fabricated by drop-casting NCs onto blue-emitting LED lights. Thus a simple benzoic acid posttreatment further presents the scope of use of these materials display technologies.
- Metaheuristics attribute selection model for efficient diagnosis of chronic disorders May 31, 2022
The technological advancements in the medical domain have aided in the effective collection of data such as personal information, clinical history, and disease symptoms of patients. However, the accumulation of massive quantity of data may cause errors in the diagnosis of the disease. A chronic disease dataset may be comprised of numerous symptoms and attributes where not all of them are of equal importance in disease diagnosis. A few of those attributes may be less relevant or redundant.
Through her research, Dr Priyanka from the Department of Computer Science and Engineering proposes metaheuristics driven attribute optimization techniques that can be implemented in optimizing chronic disease datasets to achieve optimal efficiency in disease risk prediction which can help in proper medical diagnosis. Her paper titled “A Decisive Metaheuristics Attribute Selector Enabled Combined Unsupervised-Supervised Model for Chronic Disease Risks Assessment” was published in the Q1 journal Computational Intelligence and Neuroscience.
This research can be used to develop a decision support system to assist medical experts in the effective analysis of chronic diseases in a cost-effective manner. The system model may be used to assist medical experts in the efficient diagnosis of chronic disease risks. In future, the research study can be further enhanced to validate the model on more complex heterogeneous datasets with varying sizes and structures. Also, deep learning methods can be employed using image-based real-time datasets.
Abstract of the Research
Advanced predictive analytics coupled with an effective attribute selection method plays a pivotal role in precise assessment of chronic disorders risks in patients. In this paper, a novel buffer enabled heuristic a Memory based Metaheuristics Attribute Selection (MMAS) model is proposed, which performs local neighbourhood search for optimizing chronic disorders data. Heart disease, breast cancer, diabetes and hepatitis are the datasets used in the research. Upon implementation of the model, a mean accuracy of 94.5% using MMAS was recorded and it dropped to 93.5% if clustering was not used. The average precision, recall and f-score metric computed were 96.05%, 94.07% and 95.06% respectively. The model also has a least latency of 0.8 sec. Thus it is demonstrated that chronic disease diagnosis can be significantly improved by heuristics based attribute selection coupled with clustering followed by classification.

Assistant professors Dr Sabyasachi Mukhopadhyay and Dr Imran Pancha from the Department of Physics and the Department of Biological Sciences, respectively, along with Ms Ashwini Nawade, a PhD student of the Department of Physics, have developed a method to integrate plant proteins in the solid-state electronic circuits and utilize the biological functionality to produce a thin film, cost-effective photodetector. Their paper entitled Electron Transport across Phycobiliproteins Films and its’ Optoelectronic Properties has been published in the ECS Journal of Solid State Science and Technology with an Impact Factor of 2.07. It is an interdisciplinary research project between the Department of Biotechnology and Physics.
Explanation of the research
Biomolecules such as proteins, peptides being the most crucial life-forms, have an intimate relationship with various life activities for biological functions. The contemporary work with biomolecules mainly focuses on its evolving potential associated with nanoscale electronics where proteins and peptides are integrated as sensing materials. The researchers explored the optoelectronics functionality of combined proteins known as phycobiliproteins. They investigated electron transport behavior across the phycobiliproteins films under dark and white light illumination. The research affirms that the photochemical activity of the protein is more stable in a solid-state/ thin-film with tightly bonded water molecules than its presence in a buffer solution. Furthermore, the studies demonstrate that phycobiliproteins films modulate their electrical conductivity within their different conformation states. Researchers speculate that the electrical conductance variation could originate from the chemical alteration of cysteine-conjugated bilin chromophores to protein and the electrostatic environment around the chromophores.
The research explores the photochemical properties and electrical transport efficiency of phycobiliproteins (PBPs) films. In addition, it investigates the optoelectronics functionality of PBPs films by studying electron transport behavior across the protein films under a dark state and white light illumination. The researchers proposed to develop a photodetector with the protein film in the future.

“In a properly automated and educated world, then, machines may prove to be the true humanizing influence. It may be that machines will do the work that makes life possible and that human beings will do all the other things that make life pleasant and worthwhile.”
― Isaac Asimov
The urge to get exposed to a more diversified learning approach is understandable. Choosing a major that can help develop essential life skills while gaining a broader world perspective can be a great stride in your career. Liberal arts have always been an underrated field of study with numerous unexplored scopes. However, there is a shift in the air since the increasingly evolving world demands the production of skilled professionals with a knack for critical thinking. The trend is gradually spreading in the Indian educational scenario too.
India’s National Education Policy 2020 holds a greater emphasis on Liberal arts education. It envisions the holistic development of individuals through multidisciplinary, interdisciplinary, and transdisciplinary learning approaches. It insists on the need for higher education institutes to become multidisciplinary by 2040. De-compartmentalising the educational sector by breaking the rigid barrier between professional and liberal education is one of its major agendas. Educational structures in India are thus getting more flexible while contemplating the future of Liberal arts education. The rapidly changing employment landscape and the forthcoming industrial revolution clearly imply the extreme relevance of Liberal arts education. This calls the world’s attention towards the broader aspects of the stream of Liberal arts.
The stream of Liberal arts
The term liberal arts have roots in the classical Greek concept of a diversified education that focuses on the intellectual cultivation of the mind. The education of the Greeks in those days included different areas ranging from grammar to geometry and music. Liberal arts in the present day offer a wide range of majors and minors. These options fall into the more significant categories of humanities, social sciences, and natural sciences. Liberal arts education evokes the ability to analyse socio-political, economic, and environmental problems while being contemplative and creative. These abilities are highly relevant in current social circumstances, especially in India.
Liberal arts in the era of uncertainties
In an age that keeps updating itself, the fear of getting outdated is real. Living in a world constantly exposed to digitization, outsourcing, automating, etc., will demand fierce competence from the jobseekers. What matters is not what you learned over the years but how you learned all those things. The chances of the things you learned getting outdated are higher, but not how you perceived that knowledge.
Liberal arts as a learning subject becomes highly relevant in this scenario. Students from a liberal arts background will have much more to contribute to the ever-advancing society than the students from other streams. Liberal arts nurture the abilities of problem-solving and critical thinking. It trains the learner to think out of the box and develop original solutions.
Why Liberal arts
Liberal arts majors have the privilege of entering varying career paths due to the holistic approach the learning process holds. The possibilities are never limited. The discipline of liberal arts targets to provide a general idea regarding the subject matter and trains to think critically. The skills they earn are not restricted to a specific technical profession. Writing, critical thinking, and research skills are continuously refined through exposure to various subject matters. The job market offers opportunities for liberal arts students in science, technology, engineering, business, and many other fields. Every mainstream working ecosystem will require the input of a liberal arts major.
Advantages of pursuing a liberal arts course
Democratised educational process
Modern liberal arts education is armed with a curriculum that promotes breadth as well as the depth of knowledge. The curriculum is sufficiently flexible and gives prominence to the student’s choice. They get to play a significant role in shaping their program. This facilitates the democratisation of the educational process.
Diverse disciplines and broader perspectives
Liberal arts education provides exposure to diverse disciplines of study, which makes the learner capable of gaining a broader perspective of the field they prefer. A positive mindset, readiness to look at the world with enthusiasm, and innovative learning strategies will benefit any organization.
Thinking capacity and expanded worldview
Obtaining knowledge will help the learner gain skills in a particular area, but it also helps develop thinking capacity. Liberal arts education makes sure to guard the learners with an ability to understand and widen their knowledge limits. It nurtures the enthusiasm of the learner. This, in turn, helps to adjust the lens with which they view the world around them.
Different thinking processes
Liberal arts education lets you understand the importance of different thinking processes in every learning environment. Be it creative, analytical, or critical, a Liberal arts major knows when and how to assert these thinking processes. Challenging the preconceived notions and showing the courage not to follow the crowd is a remarkable impact liberal arts education has on the learner. This is a much-needed quality an individual should aspire to master.
Flexibility
A liberal arts student knows how to build skills based on the broader foundational knowledge. Thus, they are very flexible in acquiring new knowledge and establishing needed skills. This will help them not settle down for one specific job for an entire lifetime.
Soft skills
Every industry needs individuals with skills that are in high demand. Some of them are effective communication, critical thinking, problem-solving, and leadership qualities. Liberal arts education prepares the students to attain these qualities.
Socially responsible learner
Liberal arts don’t focus on a specialised subject. It gives a vast knowledge and allows the learner to develop creative paths to resolve social challenges exposed to them.
Opportunity to explore and experiment
Innovative ideas, concepts, and unique experiences are always there in the vicinity of the learner. The advantages of community-based learning and peer-reviewed research are accessible to the learner. This allows them to explore and experiment with the knowledge they have.
Lifelong learning
Processing the information and thinking analytically will guide the learner to think across the disciplines. This will remain a crucial life skill that could be helpful in a variety of circumstances.
Scope of liberal arts in India
The dynamics of education is an ever-evolving process. New learning methods and diverse professions will keep popping up from time to time. With the remarkable shift that happened in the field of education, a door to a diverse set of specialized career options has opened. Not to deny the requirement for skilled professionals in the age-old job market, but the jobs will be more reasoning-oriented in the future, favoring liberal arts education. Professionals should be able to analyse the present scenario and make decisions for future changes. They should be able to think critically and be ready to absorb the constantly changing knowledge environment. This indicates the demand for liberal arts majors in the future.
Liberal arts is an interdisciplinary model of education preferred by many youngsters worldwide. Introducing the student community to the perks of liberal arts education can do wonders in a developing country like India. The advantages of opening multiple career options for the country’s youth are immaculate. Also, including and enhancing liberal arts in the mainstream education sector will help improve the global ranking of Indian educational institutions.
The advancing job market demands competitive advantages from individuals. They are looking for someone more human and connected. Along with passion and energy, they also need their employees to be flexible during changes and see things as they are.
The pace, scope, and strategies of this generation are entirely different from that of the previous one. Drastic changes in climate, artificial intelligence, way of approach, etc., will demand more extraordinary resourcefulness to sustain the updating. The diverse economy of India will make sure that the students interact with different individuals irrespective of gender, religion, class, etc. This will enhance their development as valuable employees, citizens, and, most importantly, human beings.
A liberal arts degree prepares one to withstand the uncertainties of a career. It can cope with the test of time since there are no expiry dates for critical thinking and problem-solving. Polished proficiency in writing, speaking, presenting, and collaborating is another trademark of liberal arts education. It is immensely helpful if viewed from the perspective of a job aspirant.
Enhanced cultural understanding is another valuable reward from liberal arts. Interdisciplinary studies play a significant role in building this broader understanding. The importance of cultural anthropology and international relations is relatively higher, especially in India. The list of career options emerging from liberal arts includes law, politics, social work, psychology, public relations, journalism, Civil services, and many more. These job sectors are considerable investments in the development of the country.
The ability to find out opportunities and take unexpected directions will be beneficial irrespective of the interests of your comfort zones. Arming the students with flexibility and imagination will prepare them to be confident in the continuously updating job markets. In an era where the information and options are available at your fingertips, it is your perspective that makes the difference.
Selecting a career that will not disappoint you is a hectic task in every individual’s life. Especially when you don’t really want to focus on one specific field of study.

The structure of human society is always profoundly affected by the developments happening in the domain of communication. Data security and privacy have always been a concern in the ongoing communication revolution. The Department of Computer Science and Engineering is glad to inform you that the paper, “An Efficient Spatial Transformation-based Entropy Retained Reversible Data Hiding Scheme in Encrypted Images,” has been published by Dr V M Manikandan, Assistant Professor, and his PhD student Mr Shaiju Panchikkil in “Optik Journal” with an impact factor of 2.443.
Abstract of the research
A critical issue with the current communication revolution is data security and privacy, which is an inevitable part of trustworthiness in the communication system. Hence, the applicability of the Reversible Data Hiding schemes (RDH) in this scenario is encouraging and critical, like medical image communication, satellite image transmission, etc. Earlier, we explored Arnold transform in one of our previous works to hide the secret data that uses the Convolutional Neural Network (CNN) model to design a complete RDH scheme. The proposed scheme follows a statistical approach to support recovering the cover image and the embedded information. This approach proves advantageous over the previous work following its computational capability. The scheme designed can retain the entropy of the encrypted images even after embedding the additional information, complementing the security of the encryption algorithm.
Explanation of the research
The research focuses on hiding information in an encrypted image and transmitting it to the receiver. Earlier, the researchers used the Arnold transform-based image scrambling algorithm to facilitate the data hiding. But at the receiver end, they have used a convolutional neural network model, which acts as a binary classifier to recover the image properly after extracting the hidden information. The researchers had a few overheads over there, like training the model and then sharing the same with the receiver to recover the original image efficiently. To overcome these overheads, they analysed the correlation of neighboring pixels and introduced a statistical measure at the receiver end to recover the exact image.
Social implications of the research
One of the various social implications of the research is an application concerning patient treatment. In a general scenario, during the covid 19 pandemic, people make an online consultation with the doctor by uploading their medical images. If the doctor wants to take a specialist’s opinion, he should send this image and the diagnosis report via a communication medium. The research team’s approach is meaningful in this aspect. The original image is initially encrypted, which makes it unreadable. The diagnosis report information is hidden over the encrypted image. Hence the doctor needs to send only a single file to the specialist. It is also difficult for an external agent or an unauthorized party to decode the report and the image as it is encrypted. Now it is essential to regain the original quality of the recovered image, as any degradation in the quality of the recovered image can lead to a wrong diagnosis. Hence, they have designed the recovery module carefully to extract all the hidden information and recover the original image without compromising its quality.
The researchers are in constant collaboration with Professor Yu-Dong Zhang from the University of Leicester, University Road, Leicester, LE1 7RH, UK, to introduce new strategies to elevate the embedding capacity from the current level without negotiating the quality of the recovered image.

The focus of the network keeps changing with every generation of communication technology. The 5G era is waiting for the next generation to bring a remarkable revolution in communication technologies. Applying various changes and modifying the drawbacks of 5G technology can help us to improve the features of the upcoming 6G. The Department of Electronics and Communication Engineering is delighted to inform you that the paper, “Network Resource Allocation for Emergency Management based on Closed Loop Analysis” has been published by Dr Udaya Sankar, Assistant Professor, and BTech students; Sai Jnaneswar J and VMVS Aditya, in “ ITU Journal on Future and Evolving Technologies – 2nd special issue on AI and machine learning solutions in 5G and future networks”.
Abstract of the research
Telecommunication systems being a critical pillar of emergency management, intelligent deployment, and management of slices in an affected area, will help emergency responders. Techniques such as automated management of ML (machine learning) pipelines across the edge and emergency responder devices, usage of hierarchical closed-loops, and offloading inference tasks closer to the edge, can reduce latencies for first responders in case of emergencies. This paper describes the major findings of building a Proof of Concept (PoC) for network resource allocation for emergency management using a hierarchical autonomous artificial intelligence (AI)/ML-based closed-loops in the mobile network, which was organized by the Internal Telecommunication Union Focus Group on Autonomous Network (ITU FGAN). The background scenario for this PoC included the interaction between a higher closed-loop in the Operations Support System (OSS) and a lower closed-loop in RAN (Radio Access Network) to intelligently share RAN resources between the public and emergency responder slice. Representation of closed-loop “controllers” in a declarative fashion (Intent), triggering “imperative actions” in the “underlay” based on the intent, setup of a data pipeline between various components, and methods of “influencing” lower layer loops using specific logic/models, were some of the important aspects investigated by various teams. The main conclusions are summarised in this work, along with the significant observations and limitations from the PoC as well as future directions.
Explanation of the research
This is a collaborative study where the researchers have developed and implemented a hierarchical closed-loop that autonomously handles an emergency case. This project contains several groups working on separate functions such as monitoring, computing, ML selection, and resource allocation. Some presented how the AI agents and the network can be adapted to assist mobile network users in Search, Diagnostic, and Rescue (SDAR) missions. Some integrated the implementation of the closed loops in O-RAN based software. The researcher’s role in this project is to generate the data which will be used for analysis and this gets integrated with another team. Rather than putting dummy data and analysing or creating and training a machine learning model, we use the Simu5g simulator which is library-based on OMNET++ framework to generate data, mainly resource allocation data. In Simu5g they configure the required network, set all the input parameters such as and simulate it for a specific duration of time. After simulation, the various results are obtained like SINR, throughput, resource block allocation, and many more. This data of the selected parameter results is converted into CSV files and handed over to the required for ML. This project blends all the chunks of work like monitoring, computing, ML selection, and resource combination, to facilitate network resource allocation for emergency management.
Practical implementations of the research
In this project, the researchers have gathered the simulated data and want to analyse it and apply machine learning algorithms to improve the condition of existing 5G networks. AI/ML model will help to analyse the data which helps in optimizing resource allocation. Optimization algorithms for resource allocation like Interference minimization, Throughput maximization, and many more. Optimising such parameters would be really helpful for the development of new generation networks.
Collaborations
The paper was developed as part of a build-a-thon track, “ITU AI/ML in 5G Challenge: applying machine learning in communication networks” challenge. The researchers worked under the problem statement “ITU-ML5G-PS-014: Build-a-thon (PoC) Network resource allocation for emergency management based on closed-loop analysis”. This project is guided by Dr. V Udaya Sankar under AI-Designed Wireless (AIDW) Project Simulated network scenarios using simu5g for measuring resource allocation. This build-a-thon challenge was started on June 7, 2021 and ended on November 5, 2021. The research team was placed fifth among 12 teams who participated across the world in the “build a thon” track of the global challenge. While the overall challenge saw over 600 participants across more than 80 countries, the “build a thon” track was a unique coding challenge from ITU FG AN. The team worked on the simulation of the 5G system and corresponding analysis using Simu5G from ITU global partners. After the build-a-thon, the teams that have participated in the build-a-thon under the problem statement “ITU-ML5G-PS-014: Build-a-thon (PoC) Network resource allocation for emergency management based on closed-loop analysis” were collaboratively developed the journal from the observations and results that were made during this build-a-thon.
The current research work focuses on the Implementation of a simulation environment to generate data for model training and testing purposes, and serve as a simulation underlay for testing. The simulations allow us to study various configurations and analyse them to optimize the allocations. For the later stages, various machine learning techniques can be applied for the data that was generated through simulation, and further, the comparison can be done for various machine learning techniques.
