Multivariable Optimal Control For Hemodialysis: A Physiologically-Grounded Simulation Study, Redemtus Heru Tjahjana, Ratna Herdiana, Zani Anjani H.S.M. Rafsanjani, Yogi Ahmad Erlangga

All Works

This study introduces a novel multivariable optimal control framework for hemodialysis, which uniquely integrates five physiological states (blood urea concentration, fluid volume, blood pressure, electrolytes, and hemoglobin) with three clinically adjustable inputs (ultrafiltration rate, blood flow, and dialysate composition). By employing the limited-memory Broyden-Fletcher-Goldfarb-Shanno-B (L-BFGS-B) algorithm with patient-specific box constraints, the model enforces patient-specific physiological safety limits while dynamically balancing clinical targets. Numerical simulations demonstrate the stabilization of key parameters within ±5% of clinical benchmarks (e.g., KDIGO guidelines), though deviations in the hemodynamic responses underscore the need for adaptive control in real-world scenarios. Urea clearance trajectories align with efficacy patterns …

Effects Of Elicitation Method On Functionally Relevant Item Selection In Spanish And English Monolinguals And Bilinguals, Dallin J. Bailey, Esther Barahona Wilkes

Faculty Publications

Purpose: One important decision speech language pathologists make when planning anomia treatment is the identification and selection of the specific vocabulary items to target during therapy. However, this process is not entirely straightforward. Although ‘functional relevance’ has high face validity for the identification of target items, interpretations differ, which may impact which words are selected for therapy. As such, target item selection methods vary, with resulting items impacted by the specific method used. There are also many person-level variables that may impact the functional relevance of specific items, such as the heritage language of the patient or their bilingualism status. …

Exploring Biblical Foundations In Biology, Keith Snyder Phd

The Journal of Biblical Foundations of Faith and Learning

Biologists have one of the most challenging areas of study due to the breadth of topics. Biology literally encompasses all life. Since life is based on chemical principles, which in turn are based on physical laws, we need to understand this panorama of science. Because academia in the US has pigeon-holed so much of our education, students are often unable to see the true integration of all aspects of life, resulting in a warped understanding of the interrelated complexity of our God’s creation. It is our duty to show how this intertwining of science and faith more fully represents God’s …
