Controlling Mesenchyme Tissue Remodeling via Spatial Arrangement of Mechanical Constraints
(Frontiers Media, 2022-02-18)Tissue morphogenetic remodeling plays an important role in tissue repair and homeostasis and is often governed by mechanical stresses. In this study, we integrated an in vitro mesenchymal tissue experimental model with a ... -
Robust numerical analysis of fibrous composites from X-ray computed tomography image data enabling low resolutions
(Elsevier, 2022-06-16)X-ray computed tomography scans can provide detailed information about the state of the material after manufacture and in service. X-ray computed tomography aided engineering (XAE) was recently introduced as an automated ... -
Diagonally Reinforced Concrete Coupling Beams: Effects of Axial Restraint
(American Concrete Institute, 2021-11)Two pairs of nominally identical large-scale coupling beam specimens were tested under reversed cyclic displacements. Within each pair, one specimen was free to elongate and the other had resistance to elongation during ... -
High-Strength Steel Bars in Earthquake-Resistant Reinforced Concrete T-Shaped Walls
(American Concrete Institute, 2021-01)Six large-scale reinforced concrete T-shaped slender walls were tested under reversed cyclic loading to study the effects of reinforcing bar mechanical properties on wall deformation capacity. Effects on lateral stiffness ... -
Strength and Deformation of Reinforced Concrete Squat Walls with High-Strength Materials
(American Concrete Institute, 2021-01)The behavior of reinforced concrete (RC) squat walls constructed with conventional- and high-strength materials was evaluated through tests of 10 wall specimens subjected to reversed cyclic loading. Primary variables ... -
Load Rating Reinforced Concrete Bridges without Plans: State-of-the-Practice
(American Concrete Institute, 2020-06-01)In response to Federal Highway Administration requirements, several states are in the process of ensuring all bridges within their inventories are load rated. A challenging aspect of this effort is load rating reinforced ... -
Diagonally Reinforced Concrete Coupling Beams with Grade 120 (830) High-Strength Steel Bars
(American Concrete Institute, 2020)Four large-scale coupling beams were tested under fully reversed cyclic loads to investigate the effects on behavior of diagonal bar grade (60 or 120 [420 or 830]), beam shear stress (9.5 or 14√fc′, psi [0.79 or 1.17√fc′, ... -
Girder–Deck Interface: Partial Debonding, Deck Replacement, and Composite Action
(American Society of Civil Engineers, 2019-01)Results are reported from tests of three precast, prestressed concrete girders under fatigue-type cyclic and monotonic loading conducted after deck removal and replacement. Although deck demolition altered the top surface ... -
Implementation of High-Performance Fiber Reinforced Concrete Coupling Beams in High-Rise Core-Wall Structures in the Seattle Area
(American Concrete Institute, 2011-12-27)Experimental and analytical studies that led to the incorporation of strain-hardening, high-performance fiber reinforced concrete (HPFRC) coupling beams in the design of a high-rise core-wall structure in Seattle, WA, are ... -
Seismic Behavior and Detailing of High-Performance Fiber-Reinforced Concrete Coupling Beams and Coupled Wall Systems
(American Society of Civil Engineers, 2013-08)The seismic behavior of coupling beams and walls constructed with tensile strain-hardening, high-performance fiber-reinforced concrete (HPFRC) was studied through tests of large-scale precast coupling beams and coupled ... -
Test of a Coupled Wall with High Performance Fiber Reinforced Concrete Coupling Beams
(American Concrete Institute, 2009-10-01)Results from the test of a large-scale coupled-wall specimen consisting of two T-shaped reinforced concrete structural walls joined at four levels by precast coupling beams are presented. Each coupling beam had a span ... -
Interlaboratory study of standard methods for testing multiwire steel prestressing strand
(Precast/Prestressed Concrete Institute, 2020-07)An interlaboratory study involving 19 laboratories was conducted to quantify the precision of ASTM A1061-16, Standard Test Methods for Testing Multi-Wire Steel Prestressing Strand, which describes methods for measuring ... -

Photoacoustic imaging of squirrel monkey cortical and subcortical brain regions during peripheral electrical stimulation
(Elsevier, 2021-12-17)The investigation of neuronal activity in non-human primate models is of critical importance due to their genetic similarity to human brains. In this study, we tested the feasibility of using photoacoustic imaging for the ... -
Soft Elastomeric Capacitor for Angular Rotation Sensing in Steel Components
(MDPI, 2021-10-23)The authors have previously proposed corrugated soft elastomeric capacitors (cSEC) to create ultra compliant scalable strain gauges. The cSEC technology has been successfully demonstrated in engineering and biomechanical ... -
Antimicrobial Peptide–Polymer Conjugates for Dentistry
(American Chemical Society, 2020-03-13)Bacterial adhesion and growth at the composite/adhesive/tooth interface remain the primary cause of dental composite restoration failure. Early colonizers, including Streptococcus mutans, play a critical role in the formation ... -
