Reflect-Guard: Enhancing LLM Safeguards Against Adversarial Prompts via Logical Self-Reflection

LLM safety classifiers such as Llama Guard detect overtly harmful prompts well but remain vulnerable to jailbreaks that disguise intent via role-play, fictional framing, or indirect requests. We present Reflect-Guard: Llama-Guard-3-8B fine-tuned via QLoRA to generate a distilled,...

Leading for equity: Educational leadership at the intersection of bilingualism and special education in an urban elementary school

This article examines how educational leadership is mobilized in efforts to foster equity at the intersection of bilingualism and special education in a large urban U.S. elementary school. Although bilingual education and special education (SPED) have developed robust but largely...

CRT-Theta Lifts and Toric Resolvents for Cyclotomic Mock-Theta Values: Exact Foundations for a Hecke-Projected Arithmetic Detector

For a prime p ≥ 7, the finite cyclotomic value Tp governs the odd-order radial limit of Ramanujan's third-order mock theta function f(q). This paper rewrites Tp as a centred CRT-weighted unary-theta packet, proves an explicit chamber rule for the attached winding number, and deri...

Bankruptcy Prediction from 10-K Narratives: Evidence from Interpretable Text Scores and Accounting Baselines

This study examines whether context-validated acute distress disclosures in annual Form 10-K filings improve bankruptcy-risk ranking beyond accounting variables. The analysis links U.S. Securities and Exchange Commission filing data, Item 7 Management’s Discussion and Analysis te...

Use of machine learning to enhance detection of transient astronomical phenomena in historical observatory images

Transient, star-like point sources that appear and vanish over short timescales are described in astronomical images prior to launch of Sputnik. We have reported that transient numbers diminish significantly in Earth’s shadow (shadow deficit) and are more likely within (+/-) one...
