A Novel System for Breast Cancer Diagnosis
Faculty duo from the Department of Electronics and Communication Engineering, Dr Anirban Ghosh and Dr Sunil Chinnadurai, along with their research cohort, Phanindra Rayapudi Venkata, Baswala Srujana, Gadde Saranya, and Abburi Sowgandhi (B.Tech. ECE students) have published their patent titled “A System and Method for Breast Cancer Diagnosis” (Application number: 202441088356). Their cutting-edge research presents a system to help diagnose breast cancer more accurately and efficiently using advanced image analysis techniques.
Abstract
The present disclosure discloses a system for diagnosing breast cancer that utilizes topological data analysis to transform mammogram images into meaningful diagnostic insights. It includes a data preprocessing module for image standardization and enhancement and a feature extraction module to create histograms for topological analysis. The topological data analysis module converts these histograms into Persistent Homology Diagrams (PHDs) representing topological features. An Earth Mover’s Distance (EMD) matrix is generated by a similarity metric module to compare PHDs. Representative PHDs are identified using a representative selection module, enabling accurate classification by the classification module. The system’s performance is assessed through various metrics by a performance analysis module, and a web service module provides an intuitive interface for users to upload images and receive diagnostic results. This approach enhances breast cancer detection by focusing on persistent topological features, offering improved precision and interpretability.
Figure 1. Conversion of mammograms into PHDs
Explanation of the Research in Layperson’s Terms
Here’s how the system works in simple terms:
1. Preparing the Images: Mammogram images are cleaned and adjusted to ensure they’re clear and easy to analyse. The focus is on areas that might show signs of cancer.
2. Extracting Patterns: The system looks for patterns in the images that could indicate healthy or unhealthy tissue. It turns these patterns into a visual map that represents the shape and structure of the tissue.
3. Analysing Shapes: The system uses math to study how these shapes appear and disappear as the image details change. The most persistent shapes (important ones) are kept, and random noise is ignored.
4. Comparing Images: A tool measures how similar or different these patterns are between images. This helps the system group them into healthy or cancerous categories.
5. Making a Decision: The system compares a new mammogram to its library of known patterns to decide whether it’s likely healthy or shows signs of cancer.
6. Easy to Use: Doctors can upload an image to a web-based tool and quickly get results, complete with visual explanations.
This system helps doctors by making the diagnosis process faster, more reliable, and easier to understand, which can lead to earlier and better treatment for breast cancer.
Practical Implementation/Social Implications of the Research
This research enhances breast cancer detection by enabling earlier, more accurate diagnoses and improving survival rates. Its web-based tool ensures access to advanced diagnostics in remote and underserved areas, reducing disparities in healthcare. Supporting radiologists with objective insights minimizes errors and workload, especially in resource-limited settings. Patients benefit from faster, clearer results, leading to timely and cost-effective treatment. Additionally, the innovative methods could inspire advancements in diagnosing other diseases, driving broader medical progress and improving global health outcomes.
Future Research Plans
Future research could expand this system to detect other diseases like lung or liver cancer, improve diagnostic accuracy by reducing false results, and integrate multimodal data for comprehensive analysis. Incorporating patient-specific information for personalized risk assessments, creating self-learning models, and optimizing computational efficiency could enhance its adaptability. Large-scale global trials and user-friendly interfaces would ensure effective implementation across diverse populations and healthcare systems, making the technology more versatile, accessible, and impactful.

The Anxiety of Indianness in the Making of Sindhi Literature
Very often, it is assumed that the “vernacular” language texts in India do not undergo any anxiety of proving themselves Indian while works written in English do. In her research paper, “A Literature of Frustration and Failure”: The Anxiety of Indianness in the Making of Sindhi Literature as an Indian Literature”, published in the esteemed Q2 journal Journal of Sindhi Studies, Dr Soni Wadhwa, Assistant Professor, Department of Literature and Languages, focuses on Sindhi post literary activity that unfolded in the first 20 years after independence to show that Sindhi has a history of going through anxiety of belonging in India.
Abstract
Studies of Partition frequently turn to literature to understand how displacement processes, among other things, impact aesthetics and representation. The article takes a broader view of aesthetics as representation: it demonstrates how turning to the literary archive of a moment and a community gives rise to questions about the politics of individual texts and literary historiography. Centred on Sindhi literature produced in India after Partition, it shows that examining the literary productivity of the community needs to involve questions of literature as political survival. It focuses on the earliest essays from the Sindhi literary scene in India (published in the Sahitya Akademi journal Indian Literature). The article argues that these essays register anxiety about the survival of a language trying to come into being in an already existing and complicated language-nation relationship. It unpacks three registers of anxiety visible in the literary archive to broaden the scope of the conversations around the Sindhi language and its literature.
This research has been conducted to advance interest in and conversations around Sindhi literature in India. Since Sindhi does not have a state in India, most people are not aware that it exists as a language and that it has a rich literary tradition.
After this article, Dr Soni Wadhwa intends to explore different writers, themes, and movements in Sindhi literature.
Collaborations
The research has been funded by George Mason University.

A Critical Review in Understanding Equity and Social Justice in Mathematics Education
Dr Jayasree Subramanian, Associate Professor from the Department of Mathematics, has recently published a book chapter titled “Strengthening Equity and Social Justice Research in Mathematics Education Through Critical Interrogations of White Supremacy and Settler Colonialism” in the Fourth International Handbook of Mathematics Education by Springer Publications.
Abstract
In this chapter, we contextualise a suggested approach to strengthening equity and social justice research in mathematics education by inserting the mathematics education enterprise into two world events of 2020: the global COVID-19 pandemic and the global resurgence of the Black Lives Matter movement. Our intent in doing so is to underscore how white colonialism is forever present everywhere in structures and institutions around the globe, including those of the mathematics education enterprise. The logic of both white supremacy and settler colonialism are described next and then combined into a compounding scheme of colonising white supremacist logic. To illustrate that colonizing white supremacist logic is not a manifestation of only the West, a discussion of the conflicts and contradictions of white supremacy and Brahminical supremacy in the mathematics education enterprise of postcolonial India is offered. Brief summaries of the five chapters in the “Equity and Social Justice” section of this Handbook are then provided; we highlight how the chapter authors interrogated colonialising white supremacist logic within their respective chapters and point toward additional opportunities. In concluding the chapter, we feature recent USA-based mathematics education research to illustrate different possibilities when equity and social justice research is strengthened through critical interrogations of white supremacy and settler colonialism.
About the Book
The Fourth International Handbook discusses developments not recognised or dealt with entirely in the first three Springer Mathematics Education handbooks and tackles controversial issues in the field. After starting with a provocative introductory chapter which asks whether controversy is a healthy feature of international mathematics education, the four following sections cover: (a) mathematics education in Asia; (b) the roles of theory in research and practice; (c) equity and social justice; and (d) curriculum and change. These themes are taken up in 28 chapters by 60 authoritative authors from all continents. The four sections are structured based on past, present, and future aspects.
Like the first three mathematics education handbooks, this handbook provides a valuable resource for teachers, practitioners and researchers, education policymakers, mathematicians, and graduate and undergraduate students.

Establishing an Innovative Technology for Intelligent Management of Battery Systems
Dr Satyavir Singh, Assistant Professor from the Department of Electrical and Electronics Engineering and his PhD scholar, Mr Tasadeek Hassan Dar, have published a groundbreaking research paper titled “Advanced integration of bidirectional long short-term memory neural networks and innovative extended Kalman filter for state of charge estimation of lithium-ion battery.” The research that revolves around establishing technology for intelligent management of battery systems and their sustainability for longer life has been published in the Q1 journal, Journal of Power Sources, having an impact factor of 8.1.
Further to their research, the team will continue to work on robust techniques to BMS in the future.
Abstract
The state of charge (SoC) of a battery is a crucial monitoring indicator for battery management systems and it helps to assess how much further an electric vehicle can travel. This work proposes a novel approach for predicting battery SoC by developing a closed-loop system that integrates a bidirectional long short-term memory neural network with an innovative algorithm- extended Kalman filter. A second-order equivalent circuit model is selected, and its parameters are computed using the variational and logistic map cuckoo search approach.
Further, an Extended Kalman filter is combined with an innovation algorithm to update process noise in real-time, and a bidirectional long short-term memory neural network takes the input from the Extended Kalman filter and gives the compensated error value for the final SoC estimation. 75% of dynamic stress test data from the Extended Kalman filter is used for training purposes, remaining data sets are used for testing purposes. The addressed algorithm is validated by evaluating its performance in comparison to individual algorithms and various combined approaches. Empirical analysis demonstrates that the proposed model achieves a root mean square error of 0.11% and mean absolute error of 0.1% positioning it as a valuable tool for battery management systems.

Women in Leadership: Two-Day ICSSR-sponsored Conference Come to a Successful End
The Paari School of Business hosted its Two-Day ICSSR-sponsored National Conference on the theme “Women in Higher Educational Institutions (HEIs) and Career Progression” as part of the Vision Viksit Bharat@2047 initiative on January 23 – 24, 2025. This event brought together academics, delegates, and leaders to discuss research findings and actionable solutions for advancing gender equity in academia and leadership roles.
Prof. Bharadhwaj Sivakumaran, Dean – Paari School of Business, delivered the welcome address and officially inaugurated the conference. In his address, he highlighted the significance of the conference in promoting the Viksit Bharat Programme and fostering inclusivity in education, drawing attention to the persistent gender disparity in leadership roles within Indian academia, citing that very few Indian Institutes of Management (IIMs) have female directors and only a small percentage of Indian universities are led by women Vice-Chancellors. Prof. Bharadhwaj commended the efforts of researchers like Dr Kamesh, whose ICSSR-funded study on breaking the glass ceiling effect secured a ₹20 lakh grant, which focuses on understanding and addressing barriers that limit women’s progress to leadership positions in higher education.
The first keynote address was delivered by Ms Rekha V, Vice President of HR at vCom Solutions, California, on the glass ceiling effect, and its impact on women. She began by acknowledging the efforts of the organising committee in addressing this pressing issue and shared her perspective on the systemic barriers that hinder women’s advancement in leadership roles across sectors.
Ms Rekha commented, “There is a high underrepresentation of women in senior leadership roles, for example, in the tech sector. This disparity results from various biases that obstruct their career progression.” She emphasised that the challenges extend beyond mere representation, involving deeply ingrained issues such as unconscious bias, gender stereotypes, limited access to promotions, and inequitable pay structures, despite evidence showing that women often outperform their male counterparts.
She insisted organisations make conscious efforts to address these challenges by creating awareness about them, setting up mentorship programs, advocating for pay equity, and promoting transparent promotion practices. Her statement, “Be the change, Bring the change,” served as a reminder to actively contribute to creating diverse environments that champion gender equity and work towards shattering the glass ceiling and building societies where every woman has opportunities to rise to the highest levels. The keynote address concluded with an engaging Q&A session, during which the discussion focused on the thought-provoking questions asked by the audience.
The second keynote address was delivered by Dr Syed Sadiq, a UN Women Representative from Kyrgyzstan. He commended the Paari School of Business and ICSSR for their dedication to advancing women’s rights and higher-education career opportunities. Reflecting on global progress since the first International Women’s Day in 1911, he highlighted achievements like equal voting rights, leadership opportunities, and establishing landmark treaties like the UN CEDAW (Convention on the Elimination of All Forms of Discrimination Against Women).
Despite these advancements, Dr Syed spoke about the persistent challenges women face in achieving equal pay, breaking barriers to leadership, and addressing workplace discrimination. He emphasised the need for gender-inclusive policies in higher education, targeted funding, mentorship programs, and stronger laws to combat harassment and discrimination. His “Change the Trend” and “Women Deserve More” statements were inspiring. He also discussed how systemic efforts that align with the Sustainable Development Goals (SDGs) can bring meaningful change to ensure no one is left behind.
The two-day conference also had various sessions on the barriers and biases that lead to the underrepresentation of women in leadership roles. The event concluded with a felicitation ceremony where both speakers were awarded a memento in appreciation of their remarkable sessions as keynote speakers.
