Investigating the Nature of Discontinuous Shear Thickening: Beyond a Mean-Field Description
Jetin E. Thomas, Abhay Goyal, Deshpreet Singh Bedi +3
Dense suspensions can undergo a dramatic increase in viscosity at a critical value of the shear stress. This phenomenon, termed discontinuous shear thickening (DST), has been attri…
Belief Is All You Need: Modeling Narrative Archetypes in Conspiratorial Discourse
Soorya Ram Shimgekar, Abhay Goyal, Roy Ka-Wei Lee +3
Conspiratorial discourse is increasingly embedded within digital communication ecosystems, yet its structure and spread remain difficult to study. This work analyzes conspiratorial…
From Wearables to Warnings: Predicting Pain Spikes in Patients with Opioid Use Disorder
Abhay Goyal, Navin Kumar, Kimberly DiMeola +7
Chronic pain (CP) and opioid use disorder (OUD) are common and interrelated chronic medical conditions. Currently, there is a paucity of evidence-based integrated treatments for CP…
One VLM, Two Roles: Stage-Wise Routing and Specialty-Level Deployment for Clinical Workflows
Shayan Vassef, Soorya Ram Shimegekar, Abhay Goyal +3
Clinical ML workflows are often fragmented and inefficient: triage, task selection, and model deployment are handled by a patchwork of task-specific networks. These pipelines are r…
Agentic AI framework for End-to-End Medical Data Inference
Soorya Ram Shimgekar, Shayan Vassef, Abhay Goyal +2
Building and deploying machine learning solutions in healthcare remains expensive and labor-intensive due to fragmented preprocessing workflows, model compatibility issues, and str…
Using Audio Data to Facilitate Depression Risk Assessment in Primary Health Care
Adam Valen Levinson, Abhay Goyal, Roger Ho Chun Man +7
Telehealth is a valuable tool for primary health care (PHC), where depression is a common condition. PHC is the first point of contact for most people with depression, but about 25…
ChatGPT and Bard Responses to Polarizing Questions
Abhay Goyal, Muhammad Siddique, Nimay Parekh +9
Recent developments in natural language processing have demonstrated the potential of large language models (LLMs) to improve a range of educational and learning outcomes. Of recen…
How is Fatherhood Framed Online in Singapore?
Tran Hien Van, Abhay Goyal, Muhammad Siddique +7
The proliferation of discussion about fatherhood in Singapore attests to its significance, indicating the need for an exploration of how fatherhood is framed, aiding policy-making…
Predicting Opioid Use Outcomes in Minoritized Communities
Abhay Goyal, Nimay Parekh, Lam Yin Cheung +8
Machine learning algorithms can sometimes exacerbate health disparities based on ethnicity, gender, and other factors. There has been limited work at exploring potential biases wit…
Flow induced rigidity percolation in shear thickening suspensions
Abhay Goyal, Nicos S. Martys, Emanuela Del Gado
Discontinuous shear thickening (DST) is associated with a sharp rise of a suspension's viscosity with increasing applied shear rate. A key signature of DST, highlighted in recent s…
Ion specificity of confined ion-water structuring and nanoscale surface forces in clays
Francis Dragulet, Abhay Goyal, Katerina Ioannidou +2
Ion specificity and related Hofmeister effects, ubiquitous in aqueous systems, can have spectacular consequences in hydrated clays, where ion-specific nanoscale surface forces can…
Like-charge attraction at the nanoscale: ground-state correlations and water destructuring
Ivan Palaia, Abhay Goyal, Emanuela del Gado +2
Like-charge attraction, driven by ionic correlations, challenges our understanding of electrostatics both in soft and hard matter. For two charged planar surfaces confining counter…
Ordered domains in sheared dense suspensions: the link to viscosity and the disruptive effect of friction
Abhay Goyal, Emanuela Del Gado, Scott Z Jones +1
Monodisperse suspensions of Brownian colloidal spheres crystallize at high densities, and ordering under shear has been observed at densities below the crystallization threshold. W…
The physics of cement cohesion
Abhay Goyal, Ivan Palaia, Katerina Ioannidou +5
Cement is one of the most produced materials in the world. A major player in greenhouse gas emissions, it is the main binding agent in concrete, to which it provides a cohesive str…
