Umbrella Sampling Md Simulations For Retention Prediction In Peptide Reversed-Phase Liquid Chromatography., Pablo M Scrosati, Evelyn H Mackay-Barr, Lars Konermann

Chemistry Publications

Reversed-phase liquid chromatography (RPLC) is an essential tool for separating complex mixtures such as proteolytic digests in bottom-up proteomics. There is growing interest in methods that can predict the RPLC retention behavior of peptides and other analytes. Already, existing algorithms provide excellent performance based on empirical rules or large sets of RPLC training data. Here we explored a new type of retention prediction strategy that relies on first-principles modeling of peptide interactions with a C18 stationary phase. We recently demonstrated that molecular dynamics (MD) simulations can provide atomistic insights into the behavior of peptides under RPLC conditions (Anal. …

Ferrate(Vi) Transformation Of Nitrogen In Secondary Wastewater Effluent: Implications For Water And Nutrient Management, Qiufeng Lin, Zepei Tang, Hussein I. Abdel Shafy, Yang Deng

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Ferrate(VI) is a promising chemical agent for wastewater treatment. While targeting various contaminants, it can inevitably react with different water matrix constituents such as nitrogen (N) species. However, the reactions of ferrate(VI) with wastewater N compounds remain poorly understood. This study explores ferrate(VI)-mediated transformations of different N species in a secondary wastewater effluent. Ferrate(VI) oxidation minimally abated total dissolved nitrogen (TDN), while oxidizing dissolved organic nitrogen (DON) into dissolved inorganic nitrogen (DIN), primarily nitrate nitrogen (NO3--N), without noticeably altering ammonia nitrogen (NH3-N) levels. Consequently, ferrate(VI) treatment increased the fraction of bioavailable, soil-leachable NO3--N while lowering the portion of less bioaccessible …

Two prompts were used: one to generate recent eBook titles in specific health sciences fields and another to identify subject gaps in the existing collection. The first prompt revealed inconsistencies across models, with Copilot and Perplexity providing sources but also inaccuracies. The second prompt yielded more useful results, with all models offering helpful analysis …

Introducing "Identification Probability" For Automated And Transferable Assessment Of Metabolite Identification Confidence In Metabolomics And Related Studies., Thomas O Metz, Christine H Chang, Vasuk Gautam, Afia Anjum, Siyang Tian, Fei Wang, Sean M Colby, Jamie R Nunez, Madison R Blumer, Arthur S Edison, Oliver Fiehn, Dean P Jones, Shuzhao Li, Edward T Morgan, Gary J Patti, Dylan H Ross, Madelyn R Shapiro, Antony J Williams, David S Wishart

Faculty Research 2025

Methods for assessing compound identification confidence in metabolomics and related studies have been debated and actively researched for the past two decades. The earliest effort in 2007 focused primarily on mass spectrometry and nuclear magnetic resonance spectroscopy and resulted in four recommended levels of metabolite identification confidence─the Metabolite Standards Initiative (MSI) Levels. In 2014, the original MSI Levels were expanded to five levels (including two sublevels) to facilitate communication of compound identification confidence in high resolution mass spectrometry studies. Further refinement in identification levels have occurred, for example to accommodate use of ion mobility spectrometry in metabolomics workflows, and alternate …

Cryogenic Hybrid Magnonic Circuits Based On Spalled Yig Thin Films, Jing Xu, Connor Horn, Yu Jiang, Amin Pishehvar, Xinhao Li, Daniel Rosenmann, Xu Han, Miguel Levy, Supratik Guha, Xufeng Zhang

Michigan Tech Publications

Yttrium iron garnet (YIG) magnonics has garnered significant research interest because of the unique properties of magnons (quasiparticles of collective spin excitation) for signal processing. In particular, hybrid systems based on YIG magnonics show great promise for quantum information science due to their broad frequency tunability and strong compatibility with other platforms. However, their broad applications have been severely constrained by substantial microwave loss in the gadolinium gallium garnet (GGG) substrate at cryogenic temperatures. In this study, we demonstrate that YIG thin films can be spalled from YIG/GGG samples. Our approach is validated by measuring hybrid devices comprising superconducting resonators …

Transfer Learning For Thickener Control, Samuel Arce Munoz, John Hedengren

Faculty Publications

Thickener control is a key area of focus in the minerals processing industry, particularly due to its crucial role in water recovery, which is essential for sustainable resource management. The highly nonlinear nature of thickener dynamics presents significant challenges in modeling and optimization, making it a strong candidate for advanced surrogate modeling techniques. However, traditional data-driven approaches often require extensive datasets, which are frequently unavailable, especially in new plants or unexplored operational domains. Developing data-driven models without enough data representative of the dynamics of the system could result in incorrect predictions and consequently, unstable response of the controller.

Imagining Better: Requiring Trust And Imagination In Formal Engineering Education, Sneha Rathi, Jacqueline Handley

Journal of Pre-College Engineering Education Research (J-PEER)

Teachers and students bear the brunt of enacting K–12 engineering while having little input into engineering practices or values. In this reflective essay, a high school engineering teacher and an engineering education researcher reflect on a class bridging engineering and social justice. We describe the development of politicized trust with each other and students while partnering around shared commitments at a predominately Black school (e.g., Vakil et al., 2016). We also explore challenges in decentering conceptions of engineering derived from depoliticized, exclusionary practice. We demonstrate an urgent need to center educators and students from marginalized identities in formal engineering education.

The Affordable Diy Mandeye Lidar System For Surveying Caves, And How To Convert 3d Clouds Into Traditional Cave Ground Plans And Extended Profiles, Loris Redovniković, Antun Jakopec, Janusz Będkowski, Jurica Jagetić

International Journal of Speleology

The paper examines the potential use of low-cost LiDAR for cave surveying. Mobile mapping using LiDAR complements traditional speleological surveying using a polygonal traverse. These methods assist each other, with one serving as an independent control measurement for the other, ultimately resulting in a more accurate 3D model. The testing results show that achieving high accuracy and detailed cave representation is possible using open hardware and open-source software. Both spacious and well-indented cave sections and narrow passages barely passable by humans were successfully mapped. The surveying process is significantly faster than traditional cave mapping, as drawing cave sketches by hand …

Gravity Tunnel Dynamics At Non-Zero Tunnel Diameters, Shafat Mubin, Walker T. Hayes

Georgia Journal of Science

A standard exercise in undergraduate mechanics derives the trajectory of a particle that has been dropped through a gravity tunnel passing through the center of the Earth as simple harmonic oscillation, assuming uniform earth density and negligible tunnel radius. We show that when the more accurate Preliminary Reference Earth Model (PREM) density profile and non-negligible tunnel radii are taken into consideration, significant deviations from harmonic oscillation are observed along with increasing or decreasing average particle speeds. Furthermore, we report that a particle traveling along a diameter perpendicular to the axis of the gravity tunnel is unable to reach the center …
