Parsing Of Math Formulas And Chemical Diagrams Using Graph-Based Representation And Attention Models, Ayush Kumar Shah Jun 2025

Parsing Of Math Formulas And Chemical Diagrams Using Graph-Based Representation And Attention Models, Ayush Kumar Shah

Theses

Mathematical formulas and chemical diagrams appear frequently in scientific documents but are often embedded as visual content, either rasterized or vector-based images, limiting their accessibility and automated analysis. This thesis aims to bridge this gap by presenting a graph-based visual parsing framework that recognizes and parses these notations from both vector and raster image inputs in digital documents. For mathematical formulas in born-digital PDFs, we construct Symbol Layout Trees (SLTs) using a graph defined over vector-based primitives, capturing spatial relationships, avoiding relying on OCR. For born-digital chemical diagrams, we introduce a Minimum Spanning Tree (MST)-based technique that extracts molecular structure …

Mechanisms For Oxygen Vacancy Defect Migration In Srtio3/Nio Heterostructures, Anish Rajesh More Jun 2025

Mechanisms For Oxygen Vacancy Defect Migration In Srtio3/Nio Heterostructures, Anish Rajesh More

Theses

Perovskite-based oxide heterostructures display promising properties resulting from interface phenomena, making them good candidates for next-generation solid oxide fuel cell electrolytes. Amongst the different features exhibited by these interfaces, misfit dislocations play an important role in influencing ionic transport, yet their role remains poorly understood, which is the case in rock salt-perovskite interfaces too. In SrTiO3/NiO heterostructures, to comprehend interface ionic transport, we investigate oxygen vacancy migration near misfit dislocations. To this end, we developed a high-throughput framework that integrates atomistic simulations with nudged elastic band method to predict migration energy barriers across disparate interface atomic environments. By comprehensively mapping …

What Future For Peace In A World Characterized By Uncertainty And Fear?, Cedric De Coning, John, Lord Alderdice Jun 2025

What Future For Peace In A World Characterized By Uncertainty And Fear?, Cedric De Coning, John, Lord Alderdice

New England Journal of Public Policy

After World War II the leading victorious powers put in place a series of structures that became known as the ‘rules-based international order.’ Its purpose was to prevent another global conflict, and for Western countries the method was the promotion of liberal democracy. During succeeding decades, the commitment to building and securing a more peaceful world order saw the establishment of political, security, and economic institutions and civil society organizations that worked to implement it. However, the last decade has seen the increasing fragmentation and dissolution of this rules-based order and those who worked to develop it are having increasing …

Ending Wars In Times Of Uncertainty: Moral Leadership, Memory, And The Cost Of Peace, Eva Grosman Jun 2025

Ending Wars In Times Of Uncertainty: Moral Leadership, Memory, And The Cost Of Peace, Eva Grosman

New England Journal of Public Policy

In our era of ‘liquid modernity,’ ending wars requires more than ceasing hostilities—it demands ethical frameworks that address the deeper wounds of conflict. This article examines how peace processes frequently abandon those who sacrificed most, creating narratives of betrayal that undermine future stability. Using Poland’s post–World War II experience as a case study, it demonstrates how prioritizing geopolitical expediency over justice creates lasting damage to international order. Drawing on Zygmunt Bauman’s concept of liquid times, Anne Applebaum’s work on memory and abandonment, and Jonathan Sacks’s vision of moral leadership, the article argues that sustainable peace requires attention to dignity, inclusion, …

Ending War, But Beginning Peace?, Alain Tschudin Jun 2025

Ending War, But Beginning Peace?, Alain Tschudin

New England Journal of Public Policy

The end of war, conventionally marked by the implementation of a ceasefire agreement, is popularly celebrated and politically lauded in the aftermath of extreme violence. However, the so- called “silencing of the guns” is regarded only as “negative peace” or first steps away from direct violence. What about beginning Peace? Johan Galtung, esteemed for his life work in peace studies, suggests that the situation after the cessation of hostilities might be worse than the status quo ante. With reference to contemporary violent conflict in the Middle East, focusing on hostilities between Israel and Palestine, I suggest that pursuing lasting “positive …

Examining Shifts In Group-Based Motivations For Civil Conflicts In Libya, Michael D. Buhrmester, William B. Swann Jr., Brian Mcquinn, Alexis Everington, Layal Hafid, Harvey Whitehouse

New England Journal of Public Policy

This study examines shifting group alignments in Libya from 2011 to 2019, exploring their impact on continued conflict. Following up on our original research into group bonding among insurgents during the 2011 revolution, we conducted two surveys in Benghazi: first in 2015, during the aftermath of Operation Dignity, and again in 2019, as General Khalifa Haftar’s forces waged war against Tripoli. Our results show that the previously very strong group bonds with 2011 revolutionary fighters had dissipated by 2015, replaced by allegiance to Haftar’s militias. By 2019, this alignment extended to Haftar himself, reinforcing an “us versus them” mentality that …

How Gaza Sees The 2023-2025 War And The Future Of The Israel-Palestine Conflict, Scott Atran, Laura Rodriguez-Gómez, Kamil Yilmaz, Ángel Gómez

New England Journal of Public Policy

In political science and international relations, as in foreign policy and military circles, a debate is ongoing between “realists” and “moralists” regarding the importance of material factors (territory, economy, security, etc.) versus value-laden factors (justice, ideals, identity, etc.) in motivating, sustaining, and ending wars. An early 2025 representative survey of Gaza’s population considers both sets of factors in how Gazans perceive the present and future states of the Israel-Palestine conflict. Comparisons with our previous studies in the Middle East, North Africa, and Europe aim to extend this survey’s relevance beyond the current Israel-Palestine theater. The survey suggests that after waging …

Understanding The Underlying Motivations Of The Russia-Ukraine War, John Bell Jun 2025

Understanding The Underlying Motivations Of The Russia-Ukraine War, John Bell

New England Journal of Public Policy

Conflict resolution often focuses on material interests or trust building rather than the core psychological needs of the sides. Mapping the key emotional red lines of parties and addressing them creatively may offer new opportunities for peace. This article examines such an approach for the Russia-Ukraine conflict, with reflection on the Middle East where such a mapping of needs has begun. This approach leads to the concept of mutual needs satisfaction, where all sides’ critical red lines are addressed, if imperfectly. This is discussed regarding Russia, Ukraine, and the West today. As former Egyptian President Anwar Sadat demonstrated by going …
