Resistance And Adaptation: How Religion Survived A War, Iris Mascio

History Theses, Dissertations, and Student Creative Activity

This paper investigates the survival strategies employed by Bosnian Muslims during the civil wars of the 1990s, with a focus on how these strategies influenced the practice and evolution of Bosnian Islam. Drawing on primary and secondary sources, survivor interviews, and analyses of religious and social practices, the study identifies two key modes of response: adaptation and resistance. While resistance—including underground organizing, covert publications, and occasional armed defense—played a role during periods of extreme threat, it was primarily historical patterns of adaptation that enabled long-term survival and continuity. Therefore, the paper covers the challenges encountered and survival strategies used by …

Danicamtiv Reduces Myosin’S Working Stroke But Activates The Thin Filament By Accelerating Actomyosin Attachment, Brent Scott, Lina Greenberg, Caterina Squarci, Kenneth S. Campbell, Michael J. Greenberg

Physiology Faculty Publications

Heart failure is a leading cause of death worldwide, and even with current treatments, the 5-y transplant-free survival rate is only ~50 to 70%. As such, there is a need to develop new treatments for patients that improve survival and quality of life. Recently, there have been efforts to develop small molecules for heart failure that directly target components of the sarcomere, including cardiac myosin. Danicamtiv is one of these molecules; however, its direct effects on myosin’s single molecule mechanics and kinetics are not well understood. Using optical trapping techniques, stopped flow transient kinetics, and in vitro reconstitution assays, we …

Reforming The Indian Bar: The Limits Of Technological Solutions, Varsha Aithala, Karthik Suresh

Articles

A majority of Indians do not have effective access to legal services, despite the constitutional promise of access to justice. There are two intertwined reasons for this: the unavailability of a sufficient number of good quality lawyers, and the high costs of accessing legal services. The Indian legal profession is highly unequal, with ‘prestige’ being the currency of upward professional mobility. The professional regulator, the Bar Council of India, simply lacks the capacity to regulate quality. As a consequence, clients lack the information to access lawyers, and to understand the outcomes they desire from them, and the fees they have …

Not-So-Secret Authentication: The Syncbleed Attacks And Defenses For Zero-Involvement Authentication Systems, Isaac Ahlgren, Rushikesh Shirsat, Omar Achkar, George K. Thiruvathukal, Kyu In Lee, Neil Klingensmith

Computer Science: Faculty Publications and Other Works

Zero-involvement authentication (ZIA) offers a promising solution for autoprovisioning large IoT device networks by enabling devices to extract identical authentication keys from ambient environmental signals without user intervention.

However, we demonstrate that existing ZIA systems leak critical information during key negotiation when they exchange synchronization messages over public wireless channels.

Our novel passive attack, SyncBleed, exploits these leaked messages to reconstruct ZIA-generated keys, successfully cracking approximately 50% of keys in under one second in our testbed experiments.

To address this vulnerability, we introduce TREVOR (Time shift REsistant VEctor ExtractOR), which generates nearly identical bit sequences from environmental signals without exchanging …

Unilateral Facial Paralysis With Facial Nerve Enhancement On Mri In A Patient With Guillain-Barré Syndrome: A Case Report, Aaron Creswell, Abigail Zaratan, Darius Shahbazi, Shahin Shahbazi

Student Publications

Guillain-Barré syndrome (GBS) represents a spectrum of inflammatory polyradiculoneuropathies. Several variants have been reported with distinct symptom profiles. Cranial nerve involvement is relatively common, but it most often presents as bilateral facial nerve palsy at onset. We describe the case of a 66-year-old man who initially presented with extremity paresthesia that rapidly progressed to leg weakness and hyporeflexia. The diagnosis of GBS was confirmed by cerebrospinal fluid analysis, and he was treated with intravenous immunoglobulin. Following treatment, however, he developed facial hemiplegia, which was associated with facial nerve enhancement on MRI. This case represents one of the few reports of …

Quantum Pseudorandom Primitives Beyond Pseudorandom States, Chuhan Lu

Dissertations and Theses

Quantum pseudorandomness is an emerging research area. Ji, Liu, and Song defined pseudorandom states (PRSs) and pseudorandom unitaries (PRUs) as quantum analogs of pseudorandom generators and pseudorandom functions. A unitary oracle separation result between one-way functions and PRSs/PRUs, established by Kretschmer, suggests that certain quantum primitives may remain secure even if classical cryptography is compromised. This insight has spurred extensive work on quantum pseudorandomness and its applications in quantum cryptography.

Many constructions of PRSs have been established under standard assumptions, yet building a secure PRU was a long-standing open problem. This dissertation aims to narrow the gap between PRSs and …

Projections Of Lightning‐Ignited Wildfire Risk In The Western United States, Dmitri A. Kalashnikov, John T. Abatzoglou, Frances V. Davenport, Zachary M. Labe, Paul C. Loikith, Danielle Touma, Deepti Singh

Geography Faculty Publications and Presentations

Cloud‐to‐ground (CG) lightning is a major source of summer wildfire ignition in the western United States (WUS). However, future projections of lightning are uncertain since lightning is not directly simulated by most global climate models. To address this issue, we use convolutional neural network (CNN)‐based parameterizations of daily June‐September CG lightning. CNN parameterizations of daily CG lightning occurrence at each grid cell use fields of three thermodynamic variables—ratio of surface Moist Static Energy (MSE) to 500 hPa saturation MSE, 700–500 hPa lapse rate, and 500 hPa relative humidity. Applying these parameterizations to the Community Earth System Model version 2 Large …
