Eminent experts from computer science and physics domains will deliver talks for a wider audience, especially for students of basic sciences and engineering streams. The event is going to be entirely through Online mode. Dr Amit Chakraborty and Dr Soumyajyoti Biswas from the Department of Physics, SRM University-AP are the conveners of the symposium.
Programme Schedule of the Invited Lectures:
Time: 10.05 – 11.05 AM (IST)
Speaker: Prof Vineeth N Balasubramanian (IIT Hyderabad)
Title: Explainable Deep Learning: Overview, Trends and Challenges
Abstract: The last decade has seen rapid strides in Artificial Intelligence (AI) moving from being a fantasy to a reality that is a part of each one of our lives, embedded in various technologies. A catalyst of this rapid uptake has been the enormous success of deep learning methods for addressing problems in various domains including computer vision, natural language processing, and speech understanding. However, as AI makes its way into risk-sensitive and safety-critical applications such as healthcare, aerospace and finance, it is essential for AI models to not only make predictions but also be able to explain their predictions. This talk will introduce the audience to this increasingly important area of explainable AI, describe salient methods in explainable deep learning, discuss open challenges as well as present some of our recent research in this domain.
Time: 11.30 AM – 12.30 PM (IST)
Speaker: Dr Girish Varma (IIIT Hyderabad)
Title: Deep Generative Methods and Applications
Abstract: Generative methods deals with the modelling of complex high dimensional probability distributions. With the advent of deep neural networks, these methods have become more common with the discovery of new techniques like GANs. Such methods can learn to generate images, graphs etc even without using labelled data. In this talk, we will give some of the common deep generative modelling techniques like GANs, Variational Autoencoders, Normalizing Flows. We will also look at some example applications in Style Transfer, Super Resolution in Computer Vision, Conditional Generation of Molecules in Physics etc.
Time: 2.00 – 3.00 PM (IST)
Speaker: Dr Sanmay Ganguly (University of Tokyo, Japan)
Title: The Deep Relation Between Particle Physics and Machine Learning
Abstract: At the CERN Large Hadron Collider (LHC) experiment, trillions of protons get smashed with each other at very high energies every second. Remnants of this collision are collected and studied to infer what fundamental interactions are happening at the core. Analysing and extracting meaningful physics information out of this large data is a highly challenging statistical analysis, part of which has to be carried out in real-time. Modern deep learning techniques have brought a change in paradigm in the whole field, where it is observed that the application of ML truly impacts at all corners. In this presentation the speaker will try to give a general overview of the ongoing ML activities, mainly highlighting the areas in the context of LHC physics and shortly touch other branches of HEP.
Time: 3.30 – 4.30 PM (IST)
Speaker: Prof Lasse Laurson (Tampere University, Finland)
Title: Machine Learning Plastic Deformation of Crystals
Abstract: The speaker will present an overview of our recent efforts to apply machine learning to predict the fluctuating plastic deformation process of small crystals, mediated by the stress-driven motion of dislocations. To this end, we use machine learning to establish mappings between the initial state of a sample and the corresponding stress-strain curve, considering different loading protocols and geometries of the dislocation assembly. He will start with a discussion of machine learning the depinning process of edge dislocation pileups, after which he will consider the problem of machine learning-based prediction of the stress-strain response of two- dimensional systems of discrete dislocations subject to stress-controlled and strain-controlled loading.

Dr Nimai Mishra on Impact of shell thickness on photostability studies of green-emitting “Giant” quantum dots
SRM University-AP is pleased to announce that Dr Nimai Mishra, Assistant Professor, Department of Chemistry, SRM University-AP, Andhra Pradesh, along with his research group comprising of students pursuing PhD under him, Mr Rahul Singh, Mr Syed Akhil, and Ms V.G.Vasavi Dutt, has published a research article titled “Shell thickness-dependent photostability studies of green-emitting “Giant” quantum dots” in the journal Nanoscale Advances (The Royal Society of Chemistry) with an impact factor of ~4.533.
About the research:
Highly efficient green-emitting core/shell giant quantum dots have been synthesized through a facile “one-pot” gradient alloy approach. Furthermore, an additional ZnS shell was grown using the “Successive Ionic Layer Adsorption and Reaction” (SILAR) method. Due to the faster reactivity of Cd and Se compared to an analogue of Zn and S precursors it is presumed that CdSe nuclei are initially formed as core and gradient alloy shells simultaneously encapsulate the core in an energy-gradient manner and eventually thick ZnS shells were formed. Using this gradient alloy approach, we have synthesized four different sized green-emitting giant core-shell quantum dots to study their shell thickness-dependent photostability under continuous UV irradiation, and temperature-dependent PL properties of nanocrystals. There was a minimum effect of the UV light exposure on the photostability after a certain thickness of the shell. The QDs diameter of ≥ 8.5 nm shows substantial improvement in photostability compared to QDs with a diameter ≤ 7.12 nm when continuously irradiated under the strong UV light (8 W/cm2, 365 nm) for 48 h. The effect of temperature on the photoluminescence intensities was studied with respect to shell thickness. There were no apparent changes in PL intensities observed for the QDs ≥ 8.5 nm, on the contrary, for example, QDs with < 8.5 nm in diameter (for ~7.12 nm) show a decrease in PL intensity at higher temperatures ̴90°C.
More importantly, these results highlight the synthesized green-emitting gradient alloy QDs with superior optical properties can be used for highly efficient green emitters and are potentially applicable for the fabrication of green LEDs.

Best paper presentation award in the PRISM conference
Research at SRM University-AP is always geared to top the solutions that we have to our current problems. One of the most enduring issues in the field of management is crisis management. The PRISM conference has found one of our faculty member’s solution to be most beneficial and awarded him with the Best Paper Presentation Award. Dr Vimal Babu, Associate Professor-SEAMS, has come up with a response that will not only help leaders manage crisis situations with increasing efficiency but also make it possible for them to thrive in the face of adversities.
About the paper:
The purpose of the present research is to understand how global pandemic forces shaped the leadership communication strategies of the managers working in the Information Technology (IT) industry in India, in turn, how their leadership communication strategies aided in achieving agile and authentic leadership communication in relation to their own employees. It studied the leadership communication strategies of managers which facilitated them to establish emotional connect with the employees working remotely during pandemic crisis.
Abstract:
An investigation of the major themes in leadership communication strategies during times of crisis is presented in this research. It applies thematic analysis (TA) as a qualitative method to investigate effective leadership communication strategies in crises to overcome employee-centric organisational issues. Major themes and sub-themes are linked together to grasp better understanding about qualitative data. As a result, a total of five major themes emerged. Findings reveal that HR managers must consider the impact on their employees’ well-being when making verbal communication and crafting messages for their teams during times of crisis. The research developed a conceptual framework for mapping out the major themes, viz. information consumption and news making; disinformation and narrative disruption; agile communication structures; striking the balance b/w humane and factual communication and leadership communication imperatives. The themes generated substantive theory featuring agile and authentic leadership communication for the managers. As organisational leaders, managers’ challenges and communication strategies during a crisis are discussed. Future research ideas are highlighted.
Social Implications:
As a result of this research, it is now possible to deal with crisis communication challenges of managers more effectively. To avoid reacting to disinformation, one must be able to recognise it when it appears in abundance in a short period of time and recognise it when it does not. Managers of the HR department are held in high regard by their employees, who look to them for guidance and support. An agile communication structure, such as clearly stated goals, lean approvals and clarity of purpose will have a big impact upon the designing of communication strategies initiated by organisational leaders, especially when the attempts are made to interact with the employees remotely. That being said, managers need to strike a balance between human and factual communication in order to develop trust, transparency, and cooperation with their employees.
Collaborators:
The present work has been successfully carried out with the contributions of the co-researchers of the research paper, viz. Dr. Anugamini Priya Srivastava, Symbiosis International University, Pune and Mr. Vipin Kumar, Project Management Professional, BT India.
Future:
The future research plans entail working in the area of employee sustainability, well-being and career development of the workforce along with crisis management.

CSE student wins Best Paper award and cash prize in International conference
Padmaja Buggaveeti, an outstanding student from 3rd-year Computer Science Engineering at SRM University-AP, has won Best Paper (Third Prize) and a cash prize of Rs 10000 /- (Ten thousand rupees only) at the 4th ISEA Virtual International Conference on Security and Privacy 2021. Ms Padmaja, under the mentorship of her guide Dr V M Manikandan, presented a paper titled “A Novel Prediction Error Histogram Shifting-based Reversible Data Hiding Scheme for Medical Image Transmission” at the International Conference on Security and Privacy, sponsored by Information Security and Education Awareness Project Phase-II (ISEA-II) and organised by IIT (ISM) Dhanbad, India from October 27-30, 2021.
Abstract: In this paper, Ms Padmaja proposed a new prediction error histogram shifting-based reversible data hiding scheme that ensures a high embedding rate and lossless image recovery. The pixels in the images are categorised into two different classes: white pixels and black pixels based on a checkerboard pattern. To predict the black pixel value for finding the prediction, they used the average of three pixels out of 4-neighbourhood pixels, which are very close to the central pixel value. The prediction error histogram is considered for further data hiding through the histogram shifting approach. An efficient overflow handling technique is used for this. The proposed algorithms were implemented using Matlab-2020, and the experimental study of the proposed scheme is carried out on the standard medical images and natural images.
International Conference on Security and Privacy is a premier conference focused on information security and privacy. This year’s conference was sponsored by Information security and Education Awareness Project Phase-II (ISEA-II) and organised by IIT (ISM) Dhanbad, India, from October 27-30, 2021.

Dr Anil K. Suresh receives DBT grant for detoxifying sewage dyes at pilot scale
SRM University-AP is pleased to announce that Dr Anil K. Suresh, Associate Professor in the Department of Biological Sciences, has been awarded a DBT grant for his project entitled “Pilot-scale ultra-efficient fixative sewage dye-degradation by our ‘3D-megacatalyst’ generated using intact eggshell waste”.
About the Project:
Catalysis is widely used in various industrial and pharmaceutical processes to fasters the production of the desired end products. The use of inert matrices or frameworks is emerging as a “supported catalysts” arena with the potential for efficient reuse and recovery of the catalyst. We have recently generated a wide area supported catalyst utilising intact eggshell bio-waste, and the process is autogenic, facile, cost-efficient and entirely biodegradable. This supported megacatalyst can be effortlessly removed from the reaction by hand.
The current DBT-funding through Accelerated Translational Grant for Commercialization (ATGC) program is to support the technological reediness of our project for its commercialisation as a measure of Technology Readiness Level (TRL), an estimation technologies maturity and readiness for its utilisation in the commercial market. By demonstrating proof-of-concept laboratory studies, we are currently at TRL-6, and through this project, we will demonstrate pilot-scale studies for reaching the TRL-9 (Market/Operational level).
The main objectives of the proposal are:
1. Demonstrating large-volume degradations of sewage dyes at 500 L to 1000 Litres volume capacities in custom-built batch reactors.
2. Gram-scale hydrogenation of nitroarenes for the production of ~500 grams of pharmaceutical derivatives.
Social Implications of the project by Dr Anil K. Suresh:
Thousands of litres of harmful textile, paper sewage dyes that are corrosive and toxic to the environment and are unintendedly released can now be degraded into detoxified colourless by-products and water by using our “Au@megacatalyst”.
Pharmaceutically important precursors such as 4-aminophenol, propargyl amines can be produced in milligrams of quantities by using “Au@megacatalyst”, which otherwise are expensive and hard to synthesise. And most importantly, such precursors are currently being procured from China and other countries that can be avoided, and indigenous make-in-India can be conceptualised using our catalyst.
Dr Anil K. Suresh would be the principal investigator of this project, with a total outlay of Rs. 31 lacs over two years.

Eminent Lecture Series with Prof Haribabu Ejnavarzala
Technology is deeply integrated into the human society. The Department of Management Studies invites you all to the Eminent Lecture Series with our guest Prof Haribabu Ejnavarzala, for an engaging session on the economic, social, and other impacts of new technology on our lives.
Topic: Technologies are not disembodied artefacts: They are socio-technical systems
Date: December 22, 2021
Time: 10.30 am IST
About the Speaker:
Prof Haribabu Ejnavarzala is an Adjunct Senior Fellow, Research, and Information System (RIS) for Developing Countries, New Delhi and Former Vice-Chancellor-in-Charge, University of Hyderabad (UoH).
Abstract:
Technologies are socio-technical systems. The forces that shape the development of technology are social, economic, cultural, political, and ethical in nature. A technology introduced into society has consequences for interrelated domains -social (class, caste, gender relations), economic, political, cultural, and ethical. Technologies also affect the environment- water, soil, air, and non-human forms of life. In other words, technologies are embedded in societal and environmental contexts. In order to understand the values and interests underlying the construction of technological innovation and its consequences, we have to unpack the design of a given technology and its associated practices. Technologies are intricately related to the interests and meaning structures of stakeholders. In this lecture, I focus on genetic modification of crops to show that it is a socio-technical system deeply connected with interests, sometimes conflicting interests, and meanings of relevant stakeholders – farmers who use the technology, consumers of products produced by genetic modification of crops, government, regulatory agencies, judiciary, and civil society organisations in the Indian context. In conclusion, I argue that innovations that promote equity, inclusivity and justice will have more significant social acceptability.
Please join this spirited session with our eminent guest on December 22, 2021, at 10.30 am IST for the next edition of Eminent Lecture Series.
