Improving Protein Succinylation Sites Prediction Using Embeddings From Protein Language Model, Suresh Pokharel, Pawel Pratyush, Michael Heinzinger, Robert H. Newman, Dukka Kc

Michigan Tech Publications

Protein succinylation is an important post-translational modification (PTM) responsible for many vital metabolic activities in cells, including cellular respiration, regulation, and repair. Here, we present a novel approach that combines features from supervised word embedding with embedding from a protein language model called ProtT5-XL-UniRef50 (hereafter termed, ProtT5) in a deep learning framework to predict protein succinylation sites. To our knowledge, this is one of the first attempts to employ embedding from a pre-trained protein language model to predict protein succinylation sites. The proposed model, dubbed LMSuccSite, achieves state-of-the-art results compared to existing methods, with performance scores of 0.36, 0.79, 0.79 …

Tabletop Experiments For Quantum Gravity Are Also Tests Of The Interpretation Of Quantum Mechanics, Emily Adlam

Mathematics, Physics, and Computer Science Faculty Articles and Research

Recently there has been a great deal of interest in tabletop experiments intended to exhibit the quantum nature of gravity by demonstrating that it can induce entanglement. In order to evaluate these experiments, we must determine if there is any interesting class of possibilities that will be convincingly ruled out if it turns out that gravity can indeed induce entanglement. In particular, since one argument for the significance of these experiments rests on the claim that they demonstrate the existence of superpositions of spacetimes, it is important to keep in mind that different interpretations of quantum mechanics may make different …

All Works

Plants contribute significantly to the global food supply. Various Plant diseases can result in production losses, which can be avoided by maintaining vigilance. However, manually monitoring plant diseases by agriculture experts and botanists is time-consuming, challenging and error-prone. To reduce the risk of disease severity, machine vision technology (i.e., artificial intelligence) can play a significant role. In the alternative method, the severity of the disease can be diminished through computer technologies and the cooperation of humans. These methods can also eliminate the disadvantages of manual observation. In this work, we proposed a solution to detect tomato plant disease using a …

In doing so, the paper details the logical differences underlying diagnostic task performance between man and machine problem-solving: its principle of rationality, the priorities of its means of adaptation to abstraction, and the effects …

Investigating The Mechanism Of Protein And Peptide Electrospray Ionization, Elnaz Aliyari

Electronic Thesis and Dissertation Repository

Electrospray ionization (ESI) mass spectrometry (MS) is widely used for the detection and characterization of various analytes. However, many fundamental aspects of the ESI process remain poorly understood. Using molecular dynamics (MD) simulations, MS, and ion mobility spectrometry (IMS), this thesis sheds light on the mechanisms whereby gaseous analyte ions are formed from highly charged ESI nanodroplets. After a general introduction (Chapter 1), Chapter 2 focuses on the ion evaporation mechanism (IEM), i.e., the ejection of analyte ions from the droplet surface. The IEM is well established for low MW compounds, but it has remained contentious whether this pathway is …

Magma Mixing In The 874 Ad Hrafntinnuhraun Rhyolite Eruption, Chris Shannon, Kenneth Brown, D. Mcgarvie, Matthew Looke

Annual Student Research Poster Session

The exposed Icelandic crust contains ~10% rhyolite and ~90% basalt, and there is ample evidence in both recent and ancient rocks of interactions between rhyolitic and basaltic magmas. A spectacular and little-studied example is the c. 874 AD rhyolite eruption of Hrafntinnuhraun at the Torfajökull volcano, where after an initial explosive (Plinian) phase a large rhyolite lava field formed. In this lava field, one vent produced a hybrid lava which is a mechanically mixed blend of approximately 83% rhyolite and 17% basalt.

Polarized light microscopy was conducted on a suite of Hrafntinnuhraun samples that include flow-banded rhyolites, vesicular basaltic enclaves, …

Megacrystic Potassium Feldspar Magmatism In The Southern Mojave Desert, California, Claire Wolfe, Matthew Loocke, Kenneth Brown

Annual Student Research Poster Session

Investigating the textural, chemical, and chronological records preserved within crystal populations can provide insight into the processes which operate during magma ascent, emplacement, and crystallization. K-feldspar megacrysts offer an excellent opportunity to explore these records, particularly in chemically-evolved systems. Understanding megacryst formation bears on a fundamental issue in granite petrogenesis, namely whether the textural and chemical features preserved within granitoid intrusions reflect primary magmatic processes or late-stage crystallization and subsolidus reorganization. To expand our understanding of megacryst formation, we investigated a suite of K-feldspar megacrysts from the Sheep Hole Pluton (SHP) in Southern California.

SHP megacrysts are euhedral, ranging from …

Impact Of Urea On Size And Red-Edge Emission Spectroscopy Of Reverse Micelles, Tran Nguyen, Nancy E. Levinger, Bridget Gourley Ph.D

Annual Student Research Poster Session

We use reverse micelles (RMs) as our model system to study the impact of osmolytes on water at the nanoscale. Reverse micelles are characterized by w0 = [polar component]/[surfactant]. In our experiment, we focus on 5 different w0 (w0 = 1, 5, 10, 20, 40) and 3 concentrations of urea (0.5M, 1M, 2M). The Dynamic Light Scattering (DLS) illustrates a linear relationship between reverse w0 (the ratio) and size. Additionally, the DLS data indicates that the impact of osmolytes on size for small reverse micelles is not significant. Furthermore, Red-Edge Emission Spectroscopy shows a bigger impact on emission for smaller …

Hydrogen Adsorption And Isotope Mixing On Copper-Functionalized Activated Carbons, C. M. Quine, Hillary L. Smith, C. C. Ahn, A. Hasse-Zamudio, D. A. Boyd, B. Fultz

Physics & Astronomy Faculty Works

High-specific surface area (SSA) carbons were functionalized with copper nanoclusters and evaluated as potential hydrogen storage materials. The adsorption and desorption behaviors of the copper-functionalized material and pristine high-SSA carbon are compared between 77 and 400 K using adsorption isotherms up to 10 MPa and by temperature-programmed desorption of isotopic hydrogen. The high-SSA activated carbon with copper nanoclusters exhibited two desorption behaviors. (1) A desorption peak at 120 K, which was associated with physisorption on carbon, and (2) a desorption peak at 310 K, which was associated with a chemisorption process involving copper. The desorption from copper was strongly dependent …

Evidence For The ~ 1.4 Ga Picuris Orogeny In The Central Colorado Front Range, Asha A. Mahatma, Yvette D. Kuiper, Christopher S. Holm-Denoma

United States Geological Survey: Staff Publications

We present the first evidence for sedimentation and new evidence for penetrative deformation and metamorphism in the central Colorado Front Range associated with the ~ 1.48–1.35 Ga Picuris orogeny. This orogeny has recently been recognized in New Mexico, Arizona and southern Colorado and may be part of a larger active accretionary margin that includes the ~ 1.51–1.46 Ga Pinware and Baraboo events, in eastern Canada and central US respectively, that preceded the amalgamation of the Rodinian supercontinent. We demonstrate that in addition to ~ 1.4 Ga reactivation of northeast-trending Paleoproterozoic shear zones, regional folding occurred in an area south of …

Distal Exposures Of The Miocene Peach Spring Tuff In The Marble And Ship Mountains, Ca, Kelsang Shrestha, Matthew Loocke, Kenneth Brown

Annual Student Research Poster Session

The Peach Springs Tuff (PST) is a uniquely identifiable ignimbrite deposit formed by a large caldera-forming volcanic eruption during the early Miocene era. Previous investigations (e.g., Miller et al., 1986; Neilson et al., 1990) have suggested that distal ignimbrite deposits located within the Mojave region of southern California belong to the PST eruptive event. To address this hypothesis, this study investigates ignimbrite samples collected from outcrops within the Marble Mountains (n = 6) and Ship Mountains (n = 8) of southern California. Petrographic analysis reveals the abundance of quartz, sanidine, titanite, hornblende, and biotite in most ignimbrite samples. These mineral …

Diagnosing The Present With An Ecotopian Lexicon, Chirag Giri, Adam Liebman

Annual Student Research Poster Session

The book An Ecotopian Lexicon (2019) presents a collection of thirty terms and concepts from speculative fiction, anthropology, and the sociology of subcultures, each explored by a different author. The lexicon intends to address our collective “poverty of imagination” when it comes to avoiding global environmental collapse and building a different world, evidenced by the increasing dominance of apocalyptic narratives in popular culture. Although the book’s primary aim is to explore diverse concepts for imagining better futures, we have analyzed the form and content of the book for what they tell us about the present.
