The Politicization of Water: Transboundary Water-Conflict in the Indian Subcontinent

The Himalaya-Hindu Kush mountain range and the Tibetan Plateau birth ten of Asia’s most prominent rivers providing irrigation, energy, and drinking water to over two billion people across several countries today. Therefore, transboundary water sharing is a constant source of conflict for several South Asian countries that rely on rivers to support their primarily agrarian economies. In recent years, climate change has drastically increased global temperatures. As a result, the Indian subcontinent has been plagued with extreme riverine flood and drought events. Climate change-related events like riverine floods and drought, exacerbate the politicization of conflict between nations that share natural resources like water. This politicization is visible in the media coverage of conflict, and the way water-sharing issues are linked with other transboundary conflicts, especially those pertaining to national security. This paper explores the relationship between climate change and water-sharing conflicts in three South Asian nations: India, Pakistan, and Bangladesh. Through a quantitative and qualitative analysis of the national media coverage of transboundary river systems, Indus and Ganga-Brahmaputra-Meghna, this honors thesis explores how climate change affects the politicization of water-sharing conflicts between these three nations

We Deliver: The Condition of the Woman Academic in India Today

This auto-ethnographic essay draws upon Foucault’s Archaeology of Knowledge to discuss the condition of Indian women in the Humanities in academia today. While acknowledging the encouragingly gender-inclusive projections in India’s National Education Policy vision statement from 2020, I argue for more probing engagement with the concrete reality of being a woman teacher and researcher in the increasingly competitive and corporatized milieu of higher education. My methodology has been a close reading of the NEP’s vision statement to analyze recurrences of terms and concepts as pointers to its discursive field. I argue that this policy statement implicitly envisions an empowered new-age Indian woman teacher, notionally mother to all her pupils, aiding their awakening intuitively from the very heart of her experiences, skills, and memories. Against this somewhat idealized feminine ecology of the NEP in principle and spirit, I juxtapose the actual everyday choices and struggles of women in academic positions. Does the decolonization of education in spirit also impart actual transformative agency to women academics? Will women be listened to? Not one essential woman, but heterogeneous women—women across different strata, identities, professional spaces, and ideologies? Above all, my essay probes the challenges and dividends of transitioning to a more home-grown teaching and research methodology derived from current Western academic models. For instance, what forms and lines of interdisciplinarity could best serve the interest of quality control in research and teaching? In the third and last section, I argue that women are equal contributors in the discourse of academics in the future. We are committed stakeholders that can help enhance collective performance and efficiency in ways that are commensurate and compatible with our particular needs, contexts, restraints, aptitudes, and encumbrances. I conclude my essay by urging colleagues in academia, women and men, to recognize that we can truly deliver on this challenge only in a spirit of intellectual, ethical, and interpersonal collaboration and collegiality

Exploring magnetic coupling of solar atmosphere through frequency modulations of 3-min slow magnetoacoustic waves

Coronal fan loops rooted in sunspot umbra show outward propagating waves with subsonic phase speed and period around 3-min. However, their source region in the lower atmosphere is still ambiguous. We performed multi-wavelength observations of a clean fan loop system rooted in sunspot observed by Interface Region Imaging Spectrograph (IRIS) and Solar Dynamics Observatory (SDO). We utilised less explored property of frequency modulation of these 3-min waves from the photosphere to corona, and found them to be periodic with the ranges in 14-20 min, and 24-35 min. Based on our findings, we interpret that 3-min slow waves observed in the coronal fan loops are driven by 3-min oscillations observed at the photospheric footpoints of these fan loops in the umbral region. We also explored any connection between 3-min and 5-min oscillations observed at the photosphere, and found them to be poorly understood. Results provide clear evidence of magnetic coupling of the solar umbral atmosphere through propagation of 3-min waves along the fan loops at different atmospheric heights.Comment: This is a slight extended version of the paper accepted for publication in Bulletin of Li\`ege Royal Society of Sciences (proceedings of the third BINA workshop). arXiv admin note: text overlap with arXiv:2308.0349

Exploring source region of 3-min slow magnetoacoustic waves observed in coronal fan loops rooted in sunspot umbra

Sunspots host various oscillations and wave phenomena like umbral flashes, umbral oscillations, running penumbral waves, and coronal waves. All fan loops rooted in sunspot umbra constantly show a 3-min period propagating slow magnetoacoustic waves in the corona. However, their origin in the lower atmosphere is still unclear. In this work, we studied these oscillations in detail along a clean fan loop system rooted in active region AR12553 for a duration of 4-hour on June 16, 2016 observed by Interface Region Imaging Spectrograph (IRIS) and Solar Dynamics Observatory (SDO). We traced foot-points of several fan loops by identifying their locations at different atmospheric heights from the corona to the photosphere. We found presence of 3-min oscillations at foot-points of all the loops and at all atmospheric heights. We further traced origin of these waves by utilising their amplitude modulation characteristics while propagating in the solar atmosphere. We found several amplitude modulation periods in the range of 9-14 min, 20-24 min, and 30-40 min of these 3-min waves at all heights. Based on our findings, we interpret that 3-min slow magnetoacoustic waves propagating in coronal fan loops are driven by 3-min oscillations observed at the photospheric foot-points of these fan loops in the umbral region. We also explored any connection between 3-min and 5-min oscillations observed at the photospheric foot-points of these loops and found them to be weakly coupled. Results provide clear evidence of magnetic coupling of the solar atmosphere through propagation of 3-min waves along fan loops at different atmospheric heights.Comment: Accepted for publication in MNRA

Prevalence and assessment of the risk factors of stress urinary incontinence in gynaecology out patients in a tertiary care centre

Background: Stress urinary incontinence (SUI) is the complaint of involuntary leakage of urine during increased abdominal pressure in the absence of detrusor contraction. Although not a life-threatening condition, stress urinary incontinence causes various physical, psychological, and sexual problems for millions of women and their families. Although these conditions are highly prevalent, they are not often reported by patients. This was the reason for the study; to find out the prevalence and the associated risk factors.Methods: A total of 400 patients presenting in the gynaecology outpatient department with various complaints were studied. A detailed history was taken, and examination was done. Urine microscopy and culture studies were done and whenever found positive; the infection was treated. Bonney’s test was done on full bladder.Results: Stress urinary incontinence was diagnosed in 41 (10.30%) of the women. The most common co morbidity was found to be tuberculosis and other lung diseases. Among the study population, 4% of women had culture positive urinary tract infection.Conclusions: Stress urinary incontinence was seen in 10.30% of the study population. It was seen more commonly among the elderly. Urine routine and microscopy was done for all patients complaining of leakage of urine or any other urinary complaints

Ordering through learning in two-dimensional Ising spins

We study two-dimensional Ising spins, evolving through reinforcement learning using their state, action, and reward. The state of a spin is defined as whether it is in the majority or minority with its nearest neighbours. The spin updates its state using an {\epsilon}-greedy algorithm. The parameter {\epsilon} plays the role equivalent to the temperature in the Ising model. We find a phase transition from long-ranged ordered to a disordered state as we tune {\epsilon} from small to large values. In analogy with the phase transition in the Ising model, we calculate the critical {\epsilon} and the three critical exponents {\beta}, {\gamma}, {\nu} of magnetization, susceptibility, and correlation length, respectively. A hyper-scaling relation d{\nu} = 2{\beta} + {\gamma} is obtained between the three exponents. The system is studied for different learning rates. The exponents approach the exact values for two-dimensional Ising model for lower learning rates

Re-evaluating ADEM: A Deeper Look at Scoring Dialogue Responses

Automatically evaluating the quality of dialogue responses for unstructured domains is a challenging problem. ADEM(Lowe et al. 2017) formulated the automatic evaluation of dialogue systems as a learning problem and showed that such a model was able to predict responses which correlate significantly with human judgements, both at utterance and system level. Their system was shown to have beaten word-overlap metrics such as BLEU with large margins. We start with the question of whether an adversary can game the ADEM model. We design a battery of targeted attacks at the neural network based ADEM evaluation system and show that automatic evaluation of dialogue systems still has a long way to go. ADEM can get confused with a variation as simple as reversing the word order in the text! We report experiments on several such adversarial scenarios that draw out counterintuitive scores on the dialogue responses. We take a systematic look at the scoring function proposed by ADEM and connect it to linear system theory to predict the shortcomings evident in the system. We also devise an attack that can fool such a system to rate a response generation system as favorable. Finally, we allude to future research directions of using the adversarial attacks to design a truly automated dialogue evaluation system.Comment: Accepted as a long paper in the proceedings of AAAI-201

UATTA-ENS: Uncertainty Aware Test Time Augmented Ensemble for PIRC Diabetic Retinopathy Detection

Deep Ensemble Convolutional Neural Networks has become a methodology of choice for analyzing medical images with a diagnostic performance comparable to a physician, including the diagnosis of Diabetic Retinopathy. However, commonly used techniques are deterministic and are therefore unable to provide any estimate of predictive uncertainty. Quantifying model uncertainty is crucial for reducing the risk of misdiagnosis. A reliable architecture should be well-calibrated to avoid over-confident predictions. To address this, we propose a UATTA-ENS: Uncertainty-Aware Test-Time Augmented Ensemble Technique for 5 Class PIRC Diabetic Retinopathy Classification to produce reliable and well-calibrated predictions.Comment: To Appear at Medical Imaging meets NeurIPS Workshop 202
