Design considerations for piezocomposite materials for electrical stimulation in medical implants
(Taylor and Francis Group, 2022)Incidence of non-union following long bone fracture fixation and spinal fusion procedures is increasing, and very costly for patients and the medical system. Direct current (DC) electrical stimulation has shown success as ... -
Post-ischemic reorganization of sensory responses in cerebral cortex
(Frontiers Media, 2023-06-02)Introduction: Sensorimotor integration is critical for generating skilled, volitional movements. While stroke tends to impact motor function, there are also often associated sensory deficits that contribute to overall ... -
Gender, Smoking History, and Age Prediction from Laryngeal Images
(MDPI, 2023-05-29)Flexible laryngoscopy is commonly performed by otolaryngologists to detect laryngeal diseases and to recognize potentially malignant lesions. Recently, researchers have introduced machine learning techniques to facilitate ... -
Tailoring the secretome composition of mesenchymal stem cells to augment specific functions of epidermal regeneration: an in vitro diabetic model
(Frontiers Media, 2023-06-12)Introduction: Wound healing consists of a dynamic series of events that are highly dependent on paracrine factors for proper progression through the phases of wound healing. Inappropriate progression through the phases is ... -
A Finite Element Model to Study the Microscopic Behavior of Plain Concrete
(University of Kansas Center for Research, Inc., 1976-11)The object of this study is to develop a finite element model of non-homogeneous concrete, consisting of mortar and aggregate, for in-plane loading conditions. Linear elastic properties of aggregate and nonlinear properties ... -
Dynamic Fracture and Crack Arrest Toughness Evaluation of High-Performance Steel Used in Highway Bridges
(MDPI, 2023-04-26)Impact energy tests are an efficient method of verifying adequate toughness of steel prior to it being put into service. Based on a multitude of historical correlations between impact energy and fracture toughness, minimum ... -
Quality control in resting-state fMRI: the benefits of visual inspection
(Frontiers Media, 2023-05-04)Background: A variety of quality control (QC) approaches are employed in resting-state functional magnetic resonance imaging (rs-fMRI) to determine data quality and ultimately inclusion or exclusion of a fMRI data set in ... -
Optical trapping of sub-millimeter sized particles and microorganisms
(Nature Research, 2023-05-27)While optical tweezers (OT) are mostly used for confining smaller size particles, the counter-propagating (CP) dual-beam traps have been a versatile method for confining both small and larger size particles including ... -
Production of the cylinder head and crankcase of a small internal combustion engine using metal laser powder bed fusion
(Elsevier, 2023-05-03)This effort investigates the use of metal additive manufacturing, specifically laser powder bed fusion (LPBF) for the automotive and defense industries by demonstrating its feasibility to produce working internal combustion ... -
Engineering peptide-polymer hybrids for targeted repair and protection of cervical lesions
(Frontiers Media, 2022-11-25)By 2060, nearly 100 million people in the U.S. will be over age 65 years. One-third of these older adults will have root caries, and nearly 80% will have dental erosion. These conditions can cause pain and loss of tooth ... -
Engineered Peptides Enable Biomimetic Route for Collagen Intrafibrillar Mineralization
(MDPI, 2023-03-28)Overcoming the short lifespan of current dental adhesives remains a significant clinical need. Adhesives rely on formation of the hybrid layer to adhere to dentin and penetrate within collagen fibrils. However, the ability ... -
Coupled Lattice Boltzmann Modeling Framework for Pore-Scale Fluid Flow and Reactive Transport
(American Chemical Society, 2023-04-03)In this paper, we propose a modeling framework for pore-scale fluid flow and reactive transport based on a coupled lattice Boltzmann model (LBM). We develop a modeling interface to integrate the LBM modeling code parallel ... -
Deconvoluting Kinetic Rate Constants of Catalytic Substrates from Scanning Electrochemical Approach Curves with Artificial Neural Networks
(American Chemical Society, 2022-11-15)Extracting information from experimental measurements in the chemical sciences typically requires curve fitting, deconvolution, and/or solving the governing partial differential equations via numerical (e.g., finite element ... -
Minimum Joint Depth for Moment Frames with High-Strength Materials
(American Concrete Institute, 2023-01-01)This paper reports results from four large-scale interior beam column connections without transverse beams or slabs tested under reversed cyclic displacements. The specimens, which included the first of interior beam-column ... -
Water-Responsive Self-Repairing Superomniphobic Surfaces via Regeneration of Hierarchical Topography
(American Chemical Society, 2021-10-13)Superomniphobic surfaces that can self-repair physical damage are desirable for sustainable performance over time in many practical applications that include self-cleaning, corrosion resistance, and protective gears. ... -
BattX: An equivalent circuit model for lithium-ion batteries over broad current ranges
(Elsevier, 2023-06-01)Advanced battery management is as important for lithium-ion battery systems as the brain is for the human body. Its performance is based on the use of fast and accurate battery models. However, the mainstream equivalent ... -
Extraction of active, contaminant degrading enzymes from soil
