Portfoliopilot: An Agentic Platform For Financial Portfolio Management Algorithm Development And Evaluation, Jared Chan Xu Yang, Haokai Ma, Yunshan Ma

Research Collection School Of Computing and Information Systems

Developing new portfolio-management algorithms typically demands substantial programming effort, limiting rapid experimentation and excluding finance professionals without coding skills. Current robo-advisory tools offer pre-built but rigid strategies, restricting customization and experimentation. We introduce PortfolioPilot, an open-source, agentic platform that enables users to generate bespoke portfolio through natural-language descriptions. Leveraging the Anthropic Claude API, PortfolioPilot dynamically synthesizes executable TypeScript algorithms that run in the frontend with security validation. The system integrates real-time backtesting with historical market data, classical optimization algorithms (Markowitz, LSTM, ARIMA), and interactive performance visualizations.

Potent But Stealthy: Rethink Profile Pollution Against Sequential Recommendation Via Bi-Level Constrained Reinforcement Paradigm, Jiajie Su, Zihan Nan, Yunshan Ma, Xiaobo Xia, Xiaohua Feng, Weiming Liu, Xiang Chen, Xiaolin Zheng, Chaochao Chen

Research Collection School Of Computing and Information Systems

Sequential Recommenders, which exploit dynamic user intents through interaction sequences, are vulnerable to adversarial attacks. While existing attacks primarily rely on data poisoning, they require large-scale user access or fake profiles, thus lacking practicality. In this paper, we focus on the Profile Pollution Attack that subtly contaminates partial user interactions to induce targeted mispredictions. Previous PPA methods suffer from two limitations, i.e., i) overreliance on sequence horizon impact restricts fine-grained perturbations on item transitions, and ii) holistic modifications cause detectable distribution shifts. To address these challenges, we propose a constrained reinforcement driven attack CREAT that synergizes a bi-level optimization framework …

Nondeterministic Polynomial-Time Problem Challenge: An Ever-Scaling Reasoning Benchmark For Llms, Chang Yang, Ruiyu Wang, Junzhe Jiang, Qi Jiang, Qinggang Zhang, Yanchen Deng, Shuxin Li, Shuyue Hu, Bo Li, Florian T. Pokorny, Xiao Huang, Xinrun Wang

Research Collection School Of Computing and Information Systems

Reasoning is the fundamental capability of large language models (LLMs). Due to the rapid progress of LLMs, there are two main issues of current benchmarks: i) these benchmarks can be crushed in a short time (less than 1 year), and ii) these benchmarks may be easily hacked. To handle these issues, we propose the ever-scalingness for building the benchmarks which are scaling over complexity against crushing, instance against hacking and exploitation, oversight for easy verification, and coverage for real-world relevance. This paper presents Nondeterministic Polynomial-time Problem Challenge (NPPC), an ever-scaling reasoning benchmark for LLMs. Specifically, the NPPC has three main …

Evaluating Large Language Models For Line-Level Vulnerability Localization, Jian Zhang, Chong Wang, Anran Li, Weisong Sun, Cen Zhang, Wei Ma, Yang Liu

Research Collection School Of Computing and Information Systems

Recently, Automated Vulnerability Localization (AVL) has attracted growing attention, aiming to facilitate diagnosis by pinpointing the specific lines of code responsible for vulnerabilities. Large Language Models (LLMs) have shown potential in various domains, yet their effectiveness in line-level vulnerability localization remains underexplored. In this work, we present the first comprehensive empirical evaluation of LLMs for AVL. Our study examines 19 leading LLMs suitable for code analysis, including ChatGPT and multiple open-source models, spanning encoder-only, encoder-decoder, and decoder-only architectures, with model sizes from 60M to 70B parameters. We evaluate three paradigms including few-shot prompting, discriminative fine-tuning, and generative fine-tuning with and …

Interpretable Multimodal Zero Shot Ecg Diagnosis Via Structured Clinical Knowledge Alignment, Jialu Tang, Hung Manh Pham, Ignace De Lathauwer, Henk S. Schipper, Yuan Lu, Dong Ma, Aaqib Saeed

Research Collection School Of Computing and Information Systems

Electrocardiogram (ECG) interpretation is essential for cardiovascular disease diagnosis, but current automated systems often struggle with transparency and generalization to unseen conditions. To address this, we introduce ZETA, a zero-shot multimodal framework designed for interpretable ECG diagnosis aligned with clinical workflows. ZETA uniquely compares ECG signals against structured positive and negative clinical observations, which are curated through an LLM-assisted, expertvalidated process, thereby mimicking differential diagnosis. Our approach leverages a pre-trained multimodal model to align ECG and text embeddings without disease-specific fine-tuning. Empirical evaluations demonstrate ZETA’s competitive zero-shot classification performance and, importantly, provide qualitative and quantitative evidence of enhanced interpretability, grounding …

The Right To Seek Joy, Tyler Rose Clemons

Faculty Publications

Within the past three years, roughly half of American states have restricted access to gender-affirming medical treatment for children. In this article, I argue that these bans violate transgender children’s right to liberty guaranteed by the Fourteenth Amendment’s Due Process Clause. I do so by excavating the Framers’ understanding of liberty as the right to seek joy. Rooted in the philosophies of John Locke and Epicurus, the Framers understood liberty as the right to make important life decisions according to one’s subjective preferences without undue interference from the government. Based on this understanding, I develop a new framework for substantive …

Abuse Of Contract: A Proposal For A New Cause Of Action, Miriam A. Cherry

Faculty Publications

With the growth of online commerce and the platform economy, many companies are including provisions in their online terms and conditions that extend far beyond what reasonable consumers would expect. Some terms and conditions purport to bind customers to separate contracts in future transactions that have little to do with the first contract. Other boilerplate purports to cover family members of the customer who created an account. Some retailers have argued that people shopping in their brick-and-mortar stores are subject to terms and conditions because those shoppers had at some point previously created an online account. For example, Disney argued …

21st Century Perspective On The Changing Pattern Of Nerve Injuries From Gunshot Wounds In The U.S., Thomas A. Decoster

Western Journal of Orthopaedics

Gunshot wounds (GSWs) with nerve injuries in the 21st century differ significantly from those reported in the 20th century. The vast majority are now low-velocity civilian injuries, in contrast to high-velocity military injuries previously reported. The rate of nerve injury in civilian GSWs is approximately 5%, compared with the 30% reported in military cohorts. However, the most common pattern of nerve injury in the current civilian population is neurotmesis and partial neurotmesis, in contrast to the majority axonotmesis of the military cohorts. In the 20th century, treatment generally consisted of watchful waiting for signs of spontaneous recovery over three months …

Peripheral Nerve Repair And Reconstruction: Current Techniques, Adjuncts, And Emerging Therapies, Niklaus Skipp, Lana Dokic, Christina Wassef, Jazzlyn Gonzalez, Ana Love, Heather Mercer, Deana Mercer

Western Journal of Orthopaedics

Peripheral nerve injuries require reconstruction when direct, tension-free repair is not possible. A range of reconstructive strategies are used to restore continuity and promote axonal regeneration, including graft-based reconstruction, nerve transfers, conduit-based repair, supercharged end-to-side augmentation, and emerging regenerative therapies. Autologous interfascicular nerve grafts and vascularized grafts remain established techniques, whereas processed nerve allografts provide a donor-sparing alternative. Nerve transfers are increasingly used for proximal injuries with long regeneration distances, and conduits are an option for gaps shorter than 5 mm. Nerve-wrapping techniques are used to reduce perineural scarring and preserve gliding in complex or revision cases. Emerging adjunctive therapies, …

Exploring The Interaction Between Cranial Nerves V And Vii In Chronic Eyelid Myokymia: A Case Report, Karina Miramontes, Adam Walsh, Tomas Tafoya

Western Journal of Orthopaedics

Eyelid myokymia involves involuntary contractions of the orbicularis oculi muscle and is commonly associated with stress, fatigue, and craniocervical factors. Emerging evidence suggests that altered trigeminocervical interactions and craniomandibular muscle tension may contribute to symptom persistence; however, the condition remains underrecognized in physical therapy. This report describes a 65-year-old woman with chronic benign eyelid myokymia and cervical pain who completed 12 physical therapy sessions that included suboccipital functional dry needling, temporomandibular soft-tissue mobilization (STM), and cervical stabilization exercises. A reduction in eyelid myokymia was first observed at the fifth visit, coinciding with the initiation of temporomandibular STM. These findings suggest …

Median Nerve Intraneural Hematoma As An Intraoperative Finding During Carpal Tunnel Release: A Case Report, Ana Silva, Gil Gonrtre, Nikalus Skipp, Ana Love, Deana Mercer

Western Journal of Orthopaedics

Carpal tunnel syndrome (CTS) is the most common compressive neuropathy and typically progresses slowly. Intraoperatively, flexor tenosynovitis, nerve edema, or hourglass deformity may be observed. In rare cases, acute compression symptoms occur due to mass effect on the nerve. Intraneural hematoma of the median nerve is uncommon and has been reported primarily in acute CTS cases associated with trauma. This report describes an 87-year-old patient with a history of mild CTS who underwent carpal tunnel release due to worsening symptoms. After the initial incision, a thickened flexor retinaculum, an hourglass deformity of the median nerve, and an intraneural hematoma were …

Proximal Iliotibial Band Rupture In A 74-Year-Old High-Level, Female Athlete: A Case Report, Jeremiah M. Langsfeld, Joseph Esquibel, Dustin L. Richter

Western Journal of Orthopaedics

A 74-year-old female endurance athlete presented with progressive pain over the left proximal and lateral hip distal to the iliac crest. Symptoms developed over three weeks, impairing weightbearing. Magnetic resonance imaging demonstrated a high-grade tear of the proximal iliotibial band at its iliac crest insertion. The patient was treated nonoperatively and returned to high-level, asymptomatic competition three months after symptom onset. This case offers a nonoperative approach to the rare presentation of a proximal iliotibial band rupture.

Arthroscopic Treatment Of Extensive Synovial Chondromatosis Of The Knee: A Case Report, Gaurav Singh, Bhavna Singh, Rebecca Peebles, Justin Bartley

Western Journal of Orthopaedics

Synovial chondromatosis (SC) is a rare, benign monoarticular disorder characterized by intra-articular cartilaginous loose bodies resulting from synovial metaplasia, most commonly affecting the knee. The authors present the case of a 44-year-old man with progressive, debilitating left knee pain, mechanical symptoms, and functional limitations unresponsive to conservative treatment. Radiographs were unremarkable, but magnetic resonance imaging (MRI) demonstrated multifocal noncalcified intra-articular bodies consistent with SC. The patient underwent arthroscopic debridement of the knee with limited synovectomy. Intraoperative findings included innumerable intra-articular cartilaginous loose bodies throughout the knee, synovial proliferation, and grade II chondromalacia. At three months postoperatively, the patient had regained …

Arthroscopic Management Of A Loose Body In The Pisotriquetral Joint: A Case Report, Giovanni Chioda, Tomas Holy, Nicholas Newcomb, Nathan Morrell

Western Journal of Orthopaedics

The pisotriquetral joint is the smallest of the four joints comprising the wrist and is a source of ulnar-sided wrist pain. This condyloid joint connects the pisiform to the triquetrum and is supported by several surrounding ligaments. A variety of pathologies may affect the pisotriquetral joint, including the presence of loose bodies. Because of its small size and the inherent difficulty of visualization, the pisotriquetral joint is often overlooked as an independent joint. Techniques for arthroscopic visualization and loose-body removal have previously been described using the 6R and 4-5 portals. In the following case report, the authors describe successful visualization …

Play-Based Learning In Private International Preschools In Cairo: Teachers' Perspectives, Kesha L. Stovall

Theses and Dissertations

This thesis explores how play-based learning is practiced and contextualized in private, international preschools in Cairo, Egypt through the perspective of teachers. It calls upon both historical and contemporary theories of play and play pedagogies ranging from the times of Plato and Al-Farabi to the 21st century with Montessori and Dewey. Using a contemporary theory of play presented by Stuart Lester and Wendy Russell as a guiding framework, it examines how play and play-based learning are implemented, shaped and even challenged in a Cairene context. These contexts include sociocultural factors such as parents’ expectations and aspirations, institutional barriers, teacher development …

Ottoman Wikālas In Cairo: Islamic Architecture Beyond The Mosque, Yumna Moussa

Theses and Dissertations

This thesis traces one of the largest architectural typologies in Cairo: the wikāla, a type of urban caravanserai unique to Egypt. Estimated to have reached more than five hundred buildings by the 18^th century, the wikāla was the building of choice for most patrons in Ottoman Cairo. This study initially investigates the evolution of commercial architecture within the Islamic city. It then explores the defining architectural features of Cairene wikālas built between the 16^th and 18^th centuries—their plans, decorative/iconographic programs, and urban distribution—based on waqfiyyas, chronicles, travelers’ accounts, and photographic archives. Since many of …

On The Reasonableness Of Religious Belief According To W. James' "The Will To Believe" With Reference To Alvin Plantinga's “The Nature Of Necessity”, Maria Gadelrad Shenouda Nakhla

Theses and Dissertations

Analytically, I follow William James's approach in his paper "The Will to Believe" to demonstrate that holding a religious belief is reasonable and it is not incompatible with being a philosophy scholar. I do this through explaining the way James addressed the main obstacle that Clifford puts against belief (in general) which is ‘the lack of sufficient evidence’. Clifford claims that belief cannot be accepted without evidence on it.

James breaks apart this obstacle through many steps. First, analyzing the nature of belief itself, showing that belief cannot be attained based on intellectual grounds alone (which needs sufficient evidence), but …
