Faculty and Student Publications

Introduction—Myosin II has been investigated with optical trapping, but single motor-filament assay arrangements are not reflective of the complex cellular environment. To understand how myosin interactions propagate up in scale to accomplish system force generation, we devised a novel actomyosin ensemble optical trapping assay that reflects the hierarchy and compliancy of a physiological environment and is modular for interrogating force effectors.

Methods—Hierarchical actomyosin bundles were formed in vitro. Fluorescent template and cargo actin filaments (AF) were assembled in a flow cell and bundled by myosin. Beads were added in the presence of ATP to bind the cargo AF …

Advancing Water Resource Assessment With Insar Data And Subsidence Models, Ryan G. Smith

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Over the past three decades, Interferometric Synthetic Aperture Radar (InSAR) has grown from a tool for monitoring earthquakes and other massive signature deformation events to tracking the subtle, slow deformation processes associated with changes in groundwater storage. Improvements in time-series processing and noise reduction, as well as improved models of deformation, have enabled this advancement. InSAR has proven to be a valuable tool for characterizing elastic deformation in regions experiencing little long-term storage loss, as well as inelastic deformation in over-stressed aquifers.

Experimental Study On Co2-Sensitive Polyacrylamide As Potential In-Situ Sealing Agent For Co2 Leakage Pathways In Geological Storage Sites, Iris Laihmen Quan Lopez

Theses and Dissertations

As the world pushes for ‘greener’ technologies and carbon neutrality, efforts have focused on creating novel ways to mitigate humankind’s carbon footprint. Carbon capture and storage (CCS) has become a prevalent technique that has proven to be an effective long-term method to safely relocate excess carbon dioxide (CO₂) into subsurface formations. However, CCS is a newer technique which requires constant monitoring due to potential leakage pathways present in CO₂ storage sites; therefore, a preventive approach to seal leakage pathways is recommended. This dissertation explores the potential of CO₂-sensitive polyacrylamide (CO₂-SPAM) as a novel …

A Novel Approach To Estimate Rock Strength Parameters From Multistage Triaxial Tests (The A-Has Method), Abo Taleb T. Al-Hameedi, Husam H. Alkinani, Shari Dunn-Norman, Munir Aldin, Sudarshan Govindarajan

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Rock strength parameters are vital to creating robust geomechanical models for wellbore stability, sand production, and hydraulic fracturing. Static rock strength parameters can be estimated from single stage triaxial tests (SST) or multistage triaxial tests (MST). Although SST tests are the most accurate way to estimate rock strength parameters, SST tests require at least four to five core plugs to estimate rock strength parameters. Thus, MST tests are used as an alternative method to estimate rock strength parameters from only one core plug to overcome the limitation of materials and save time and money. However, the currently used method to …

Microbiological, Environmental, And Compositional Factors In Efficacy Of Micp Treatment In Clayey Soils, Somaye Asghari

Boise State University Theses and Dissertations

Expansive clayey soils can cause billions of dollars of damage to infrastructure such as roads and foundations annually. Researchers propose many techniques (e.g., pre-wetting, soil replacement, and chemical stabilization) to improve the mechanical properties of these soils; however, some of these methods are impractical in certain situations, and are unsustainable in others due to the economic and environmental impacts. One possible method for enhancing soil’s mechanical properties is Microbial Induced Calcium Carbonate Precipitation (MICP). This environmentally friendly technique is a biological process where microbes play a key role in precipitating calcium carbonate. This precipitating calcium carbonate can coat soil particles …

Evaluation Of Various Data Acquisition Scenarios For The Retrieval Of Seismic Body Waves From Ambient Noise Seismic Interferometry Technique Via Numerical Modeling, Haitao Cao, Erdi Apatay, Garvie Crane, Boming Wu, Ke Gao, Roohollah Askari

Michigan Tech Publications, Part 1

Seismic interferometry is often proposed as a cost-efficient technique for reservoir monitoring including CO2 sequestration due to its low cost and environmental advantages over active source imaging. Although many studies have demonstrated the ability of seismic interferometry to retrieve surface waves, body wave imaging remains challenging due to their generally lower amplitudes of body waves in seismic interferometry data. An optimum data acquisition strategy can help retrieve low amplitude body waves better, however, rare attempts have been made to evaluate various data acquisition strategies. In this study, we use numerical modeling to examine three different acquisition schemes to evaluate the …

Metastable Olivine Within Oceanic Lithosphere In The Uppermost Lower Mantle Beneath The Eastern United States, Fansheng Kong, Stephen S. Gao, Kelly H. Liu, Yinxia Fang, Hejun Zhu, Robert J. Stern, Jiabiao Li

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Approximately two-thirds of Earth's outermost shell is composed of oceanic plates that form at spreading ridges and recycle back to Earth's interior in subduction zones. A series of physical and chemical changes occur in the subducting lithospheric slab as the temperature and pressure increase with depth. In particular, olivine, the most abundant mineral in the upper mantle, progressively transforms to its high-pressure polymorphs near the mantle transition zone, which is bounded by the 410 km and 660 km discontinuities. However, whether olivine still exists in the core of slabs once they penetrate the 660 km discontinuity remains debated. Based on …

Novel Mlr-Rf-Based Geospatial Techniques: A Comparison With Ok, Waqas Ahmad, Khan Muhammad, Hylke Jan Glass, Snehamoy Chatterjee, Asif Khan, Abid Hussain

Michigan Tech Publications, Part 1

Geostatistical estimation methods rely on experimental variograms that are mostly erratic, leading to subjective model fitting and assuming normal distribution during conditional simula-tions. In contrast, Machine Learning Algorithms (MLA) are (1) free of such limitations, (2) can in-corporate information from multiple sources and therefore emerge with increasing interest in real-time resource estimation and automation. However, MLAs need to be explored for robust learning of phenomena, better accuracy, and computational efficiency. This paper compares MLAs, i.e., Multiple Linear Regression (MLR) and Random Forest (RF), with Ordinary Kriging (OK). The techniques were applied to the publicly available Walkerlake dataset, while the exhaustive …

Classification Of Teleseismic Shear Wave Splitting Measurements: A Convolutional Neural Network Approach, Yanwei Zhang, Stephen S. Gao

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Shear wave splitting (SWS) analysis is widely used to provide critical constraints on crustal and mantle structure and dynamic models. In order to obtain reliable splitting measurements, an essential step is to visually verify all the measurements to reject problematic measurements, a task that is increasingly time consuming due to the exponential increase in the amount of data. In this study, we utilized a convolutional neural network (CNN) based method to automatically select reliable SWS measurements. The CNN was trained by human-verified teleseismic SWS measurements and tested using synthetic SWS measurements. Application of the trained CNN to broadband seismic data …

Stratigraphically, this formation exposes carbonaceous clay with lenses of lignite and sticks of marcasite, followed by variegated clays and sandstone. The presence of variegated lithounits endows beauty to these cliffs. Varkala cliffs, edging the Arabian Sea, run for a length of 7.5 km. These cliffs, together with confined beaches, made Varkala a popular tourist destination. Several geodiversity spots within …

A Novel Numerical Model Of Gelant Inaccessible Pore Volume For In Situ Gel Treatment, Jianqiao Leng, Xindi Sun, Mingzhen Wei, Baojun Bai

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Inaccessible pore volume (IAPV) can have an important impact on the placement of gelant during in situ gel treatment for conformance control. Previously, IAPV was considered to be a constant factor in simulators, yet it lacked dynamic characterization. This paper proposes a numerical simulation model of IAPV. The model was derived based on the theoretical hydrodynamic model of gelant molecules. The model considers both static features, such as gelant and formation properties, and dynamic features, such as gelant rheology and retention. To validate our model, we collected IAPV from 64 experiments and the results showed that our model fit moderately …
