Food Reintroduction After Negative Ofcs In Pediatrics: Dietary Frequency And Caregiver Attitudes, Olivia Pietrantozzi

Honors Projects

Food allergies in pediatric populations have been gradually increasing in prevalence and present significant nutritional risks requiring strict dietary management and psychosocial challenges. Oral food challenges (OFCs) serve as a gold standard in diagnosing food allergies and determining whether allergenic foods can be safely reintroduced to an individual's diet. However, caregivers of children may still experience anxiety and barriers that delay the reintroduction of foods, which can limit diet diversity and increase the child's risk of future allergy development. This study looked to evaluate the dietary frequency of allergenic food reintroduction following negative OFCs, as well as to assess changes …

The Toll Of The Bridge: Affective Citizenship And The Negative Dialectic Of The `Promised Land' In Arab American Fiction, Muhammad Khaled Alatrash

Journal of Arabic Sciences and Humanities

Scholarship on Arab American literature frequently follows a linear decline from Mahjar-era optimism to the disappointments of post-9/11. This article complicates that trajectory by reading Khalil Gibran's The Broken Wings (1912) and Laila Halaby's Once in a Promised Land (2007) as stages of a negative dialectic—contradiction held in tension without resolution. Gibran envisions America as a sanctuary unreached by the hands of the thieves, where the self might be understood correctly rather than sorted into hostile categories. Halaby reveals how sanctuary becomes a checkpoint: inclusion demands permanent performance of harmlessness, and failure is punished not through formal exclusion but through …

From Input To Narrative: Authoring Processes In Ai-Generated Discourse, Fahad Ahmed Otaif

Journal of Arabic Sciences and Humanities

With the growing use of generative AI bots in different disciplines and professions, AI bots have been increasingly adopted to compose, revise, translate, and author content, yet without much research evaluating their quality, particularly when it comes to the processes and features of AI-authored discourse. The current study investigates, based on corpus-based evidence, the extent to which one-theme AI-generated sentences can be reorganised/turned into meaningful discourse through four AI bots (ChatGPT, Gemini, Copilot, and DeepSeek), i.e. by which discourse processes and in what coherent and cohesive patterns. These four AI-bots were fed with well-designed prompts instructing them to produce both …

Defensive Publications Series

This defensive publication discloses a passive, megalitre-class atmospheric water generator (AWG) architecture in which humid coastal air is drawn through an array of five parallel bedrock tunnels, condensed on the cool rock walls, and discharged through a mountain-slope-integrated inclined solar chimney. The rock itself is used as the primary condenser, the bedrock tunnels are dimensioned at the diameter that matches standard utility-scale tunnel-boring-machine (TBM) production, and the inclined solar chimney is routed along the natural face of the inland ridge so that the bedrock carries all structural loads and the chimney's own upper surface acts as a combined solar collector. …

Orchestrator-Worker Llm Architecture For Mitigating Prompt Injection Via Separated Privileges, Jason Mayes

Defensive Publications Series

Agentic systems powered by a large language model (LLM) can be vulnerable to prompt injection attacks, where malicious instructions hidden in untrusted data may cause the system to perform unauthorized actions. An orchestrator-worker architecture can be implemented to mitigate this risk by separating system privileges. The design can feature an orchestrator component, comprising software logic and a privileged master LLM, that manages user commands and powerful tools, alongside one or more unprivileged, sandboxed worker LLMs that process untrusted data with a restricted toolset. When a worker LLM returns data, the orchestrator LLM can be configured to encapsulate the output in …

Biologically Inspired Segmented Electric Traction Motor With Load-Adaptive Stator Recruitment And Thermal-Aware Control, Justin Miles Jorgensen

Defensive Publications Series

Abstract

This disclosure describes an electromagnetic traction motor architecture that mimics the distributed, modular torque production of biological motors (e.g., flagellar motors). The system utilizes a stator divided into independently energizable sectors (circumferential or axial). A supervisory controller dynamically “recruits” or “de-recruits” these sectors based on real-time torque demand, efficiency maps, and thermal headroom. This architecture enables improved part-load efficiency, 800V+ operation with reduced I²R losses, and “limp-home” fault tolerance by isolating degraded sectors without shutting down the entire machine.

Defensive Publications Series

Traditional Engineering Change Order (ECO) cell verification may require a full‑chip Electro‑Migration and IR (EMIR) analysis to confirm that newly integrated cells do not induce excessive IR drop failures. For large‑scale integrated circuits, this comprehensive simulation creates significant bottlenecks due to high turnaround times and intensive storage requirements. A machine learning‑based methodology is disclosed to predict dynamic IR drop specifically for ECO instances. A partition‑specific model is trained using data from a preceding stable EMIR execution. Physical and electrical parameters, including resistance, slew, load, and peak current, are extracted for new ECO cells and processed by the trained model to …

On‑Chip Current Sensor For Resistance Calibration Of High‑Speed Input/Output Peripherals, Karthikeyan Subramanian, Kasi Chunduri

Defensive Publications Series

Resistance calibration in high‑speed input/output (HSIO) physical layers typically uses dedicated automatic test equipment (ATE) channels to force current and measure voltage at an external reference pin. This traditional approach increases testing overhead and limits the capacity for concurrent multi‑site device testing. This disclosure describes a method and system for performing resistance calibration using an on‑chip current sensor. The sensor’s differential voltage sensing pins are connected to the internal resistance network. A mixed‑signal transconductor converts the detected voltage drop into a current, which is then integrated, sampled, and digitized. Internal resistance is calculated from these measurements using Ohm’s Law, and …

Reducing Test Time Through Parallel Execution Of Analog And Digital Bist Sequences, Karthikeyan Subramanian, Kasi Chunduri, Achin Grover, Gurumoorthy, Suman Jayachandra

Defensive Publications Series

Traditional test methodologies for semiconductor devices typically execute Analog and Memory Built‑In Self‑Test (MBIST) sequences in a standalone, serial fashion. This sequential approach involves separate initialization and execution phases for each test block, which contributes to total tester time. Specifically, standalone sequences for components (e.g., Phase Locked Loops (PLL), Digital to Analog Converters (DAC), memory blocks) run independently through Joint Test Action Group (JTAG) or external interfaces. The disclosed method utilizes a concurrency algorithm based on the IEEE 1687 IJTAG standard and Procedural Description Language (PDL) to interleave these test sequences. Digital and analog initialization phases may be combined, followed …

Cultivating Home: Nepali Migrants And Gardening As Everyday Rhetoric, Menuka Gurung Lama

Frontera Retórica Symposium

Rhetorical knowledge is often discussed through formal institutions and textual traditions, leaving everyday community practices underexamined. This paper engages the theme “Rhetoric from the Margins” by examining how Nepali migrants’ gardening practices in Hooksett, New Hampshire produce knowledge outside dominant academic and institutional frameworks. I ask: How do Nepali migrants use gardening as a way of making meaning, sustaining memory, and cultivating belonging in unfamiliar environments? In what ways does gardening function as a rhetorical and epistemic practice through which migrants carry and transform land-based knowledge across borders? Rather than treating gardening simply as leisure or subsistence activity, I examine …

Physically‑Aware Fault Modeling And Test Pattern Selection Using Multi‑Layer Perceptron Networks, Sandipan Sharma, Srinivas Vooka, Maheedhar Jalasutram, Pranav Murthy

Defensive Publications Series

Conventional semiconductor fault models often assume a linear correlation between fault counts and chip fallout, assigning equal weight to each fault node.  This approach fails to account for non‑linear outliers attributed to specific physical design features, leading to suboptimal fallout prediction and inefficient test pattern prioritization.  A method is disclosed that utilizes a multi‑layer perceptron network to generate physically aware fault models.  A fault feature matrix is constructed from physical design data that incorporates features (e.g., total net length, via density, proximity to power rails).  This matrix is processed by a fully connected neural network trained on production fallout data …

Hardware‑Interlocked Power Request Signaling For Secure Root‑Of‑Trust Operations, Rohit Sinha, Naved Kazi, Anchal Vijay

Defensive Publications Series

Traditional power management for secure memory operations often depends on external software to identify and request high‑voltage rails before sending commands to a secure entity. This reliance may create synchronization risks where memory programming might begin before power is stable, and involves non‑secure components inspecting secure directives, potentially exposing sensitive information. This publication describes a hardware‑interlocked handshake mechanism between a Root‑of‑Trust and a Power Manager to manage power rails on‑demand. The Root‑of‑Trust independently identifies the request for high‑voltage power and asserts a hardware request signal. The Power Manager receives a hardware interrupt, enables the indicated power rail, and returns a …
