Mansoura Engineering Journal

This study evaluates "matching frontier" methods against conventional approaches for estimating Crash Modification Factors (CMFs). Thirty-four method-model combinations were tested, including 16 frontier variants, 8 propensity-score-matching algorithms with negative binomial and mixed-effects models, and two benchmarks (empirical Bayes and cross-sectional), across multiple sample sizes and three true CMF values (0.80, 1.00, and 1.30). Of these, 30 converged successfully; 4 mixed-effects models with replacement-based matching failed due to duplicate control observations. Each scenario was evaluated across 10 Monte Carlo replications to quantify performance uncertainty.

Synthetic crash data were generated with known treatment effects, examining scenarios ranging from ideal (386 treated, 21,000 …

Remote Sensing-Based Rice Detection: Novel Indices From Optical And Sar Synergy, Kaifi Chomani

Mansoura Engineering Journal

Accurate rice mapping is challenging due to the lack of a simple, efficient approach and the complexity and limited ability of existing methods to distinguish rice fields from non-rice fields. This study proposes two novel indices: the Multispectral Rice Detection Index (MRDI), which utilises optical imagery, and the OptiRadar Rice Index (ORRI), which incorporates both optical and Synthetic Aperture Radar (SAR) data. Ground-truth data from the Cropland Cropping Systems (CROS) were used to assess the performance of both indices. The findings indicated that MRDI achieved an overall accuracy of 97.97% with perfect recall (100%) but lower precision (78.65%). However, the …

Application Of Current Enteral Nutrition Support Recommendations To Infants Born Less Than 750 Grams Or Less Than 25 Weeks' Gestation: A Critical Review, Mar Romero-Lopez, Mamta Naik, Teresa Hartman, Ann Anderson-Berry, Melissa Thoene

Journal Articles: Pediatrics

Clinicians face a paucity of evidence-based recommendations for provision of enteral nutrition in infants born < 750 g or < 25 weeks' gestation, termed "nano-preterm." Current enteral nutrition recommendations for extremely low birth weight infants may not be broadly applicable to nano-preterm infants due to physiological and developmental differences, while others may be appropriate. Key enteral nutrition-related considerations include: the unique anatomy and physiology of the gastrointestinal tract, altered metabolic capacity, availability of maternal milk and use of alternative substrates, detailed methods of initiation and advancement of enteral feeding, methods of human milk fortification, targeted requirements for macronutrient and micronutrients, and the safety and efficacy of enteral nutrition support management to optimize the growth and development of the nano-preterm infant. This comprehensive review focused on enteral nutrition provision in nano-preterm infants, thoroughly evaluating available literature and identifying knowledge gaps about the unique physiology and metabolism of the nano-preterm infant as it pertains to enteral nutrition. Ultimately, prospective multicenter research is needed to establish evidence-based guidelines to promote optimal growth and development while minimizing complications of extreme prematurity.

Robust Lc–Ms/Ms Method For Quantification Of Ascorbic Acid In Infant Formula And Heat-Processed Donor Human Milk: A Stabilization And Matrix Effects Mitigation Approach, Omar M. Al Kilani, Lee C. Winchester, Melissa Thoene, Colman Freel, Christopher Lee Shaffer, Anthony T. Podany

Journal Articles: Pediatrics

Ascorbic acid is an essential antioxidant for infant health; however, its quantification in infant formula and human milk is challenging due to matrix complexity, analyte instability, and lack of blank matrix equivalents. This study presents a simple and robust LC-MS/MS method that bypasses the need for standard addition using only 20 µL sample. The method showed excellent linearity (R² > 0.99), precision (CV < 15%), accuracy (±10%), and sensitivity (LOD < 0.0375 µg/mL). Stock and working solutions remained stable for months at −20 and −80 °C, respectively, avoiding daily preparation. Optimized extraction substantially reduced matrix effects. The method was externally validated using certified infant formula reference material and successfully applied to commercial samples, with incurred sample reanalysis showing <  20% variation. This validated method offers a practical tool for the routine quantification of ascorbic acid in heat-processed donor human milk and infant formula, with the potential for application to other matrices.

The Loss Of Symbolic Imagination And The Decline Of Christian Practice: A Blondelian Perspective, Cathal Doherty

Theology Faculty Research and Publications

The contemporary decline in Christian church-going and sacramental participation is due in part to the legacy of the Enlightenment, which valorizes the life of the mind over actual practice, a distortion due to a conceptualism of human action, widespread in Western thought, that sees in human action the mere execution of ideas. From here, it is a short step to the willful blindness that restricts our action to the execution of exclusively human ideas and concepts, to the exclusion of the divine, quietly repudiating the claims of orthodox Christian revelation that the divine intention is symbolically realized for us in …

Enoch’S Measuring, Counting, Weighing, And Balancing Creation In 2 Enoch, Andrei Orlov

Theology Faculty Research and Publications

In recent years one can see increased scholarly attention to the epistemological dimension of early Jewish apocalyptic writings and, in particular, to the ways by which divine knowledge was harvested and cultivated by the protagonists and antagonists of those early Jewish accounts. The early Enochic booklets have traditionally played a central role in these epistemological probes since they contain the earliest descriptions of the transmission and acquisition of divine knowledge in Jewish apocalypticism.  These accounts deal both with revelations unveiled by God and angels to the patriarch Enoch and with illicit transmission of divine knowledge by the rogue group of …

Intermittent Phrenic Afferent Activation Induces Phrenic Motor Plasticity, Nicole M. Popp, Taylor C. Holmes, Elizabeth A. Rozycki, Kristi A. Streeter

Physical Therapy Faculty Research and Publications

Approaches such as electrical stimulation of the phrenic neuromuscular system are currently used in humans to manage breathing impairments. We recently showed that electrical stimulation of the diaphragm muscle induces phrenic afferent-dependent plasticity. These findings highlight the need to better understand the mechanisms of afferent-mediated plasticity to guide and improve the development of novel therapies using electrical stimulation. Here, we tested the hypothesis that intermittent activation of large-diameter phrenic afferents induces phrenic motor plasticity, which, like other forms of plasticity, is pattern sensitive. We delivered inspiratory-triggered electrical stimulation using a narrow pulse width (0.1 ms) to preferentially activate large-diameter afferents, …

Multi-Axis Force Behavior In Inclined Bone Drilling, Mason Cooper, Jaxon Cooper, Adria Ruiz-Figueroa, Tomas Fanning, Celeste Joyner, Dr. Jueun Lee

IdeaFest 2026

This research investigates how drilling angle affects forces during surgical bone drilling to improve patient safety and procedure efficacy. This work addresses real surgical conditions where drilling is often non-perpendicular, frequently resulting in suboptimal or problematic outcomes. Tests on bovine bone at angles from 0° to 60° measured lateral and thrust forces. Results show lateral forces and instability increase with angle, raising likelihood of drill deflection and skidding, while thrust force stabilizes and builds more slowly. These findings provide quantitative insight to improve surgical orthopedic procedures.

Comparing Carbon Flux Dynamics In Forest And Grassland Ecosystems, Adam Wolk

IdeaFest 2026

Understanding how ecosystems exchange carbon with the atmosphere is key to predicting climate change impacts. This study examines how drought affects carbon flux (net ecosystem exchange, NEE) in grasslands versus forests using NEON data and climate variables (temperature, precipitation, drought indices). We expect grasslands to respond quickly to short-term changes, while forests show more complex, less immediate responses but greater vulnerability to severe drought. This work explores ecosystem resilience and carbon sink reliability, with implications for ecological forecasting and carbon cycle dynamics.
