Variation of Small-Strain Shear Modulus of Unsaturated Silt under Successive Cycles of Drying and Wetting
(2020-07)A new framework is developed to extend an existing small-strain shear modulus (𝐺max) model to determine 𝐺max of unsaturated silty soils along different paths of the soil water retention curve (SWRC) including the scanning ... -
Development, standardization, and validation of a biofilm efficacy test: The single tube method
(2019-10)Methods validated by a standard setting organization enable public, industry and regulatory stakeholders to make decisions on the acceptability of products, devices and processes. This is because standard methods are ... -
Measuring the polarization response of a VNIR hyperspectral imager
(2020-04)As the applications of hyperspectral imaging rapidly diversify, the need for accurate radiometric calibration of these imaging systems is becoming increasingly important. When performing radiometric measurements, the ... -
Three-Dimensional Velocity and Concentration Measurements and Simulations of a Scaled Jack Rabbit II Mock Urban Array
(2020-07)Magnetic resonance (MR) techniques provide non-invasive, three-dimensional measurements of velocity and concentration fields. Applying MR techniques to measure flows of contaminants through urban arrays provides a wealth ... -
Measuring the frequency response of the honeybee thorax
(2020-05)Insects with asynchronous flight muscles are believed to flap at the effective fundamental frequency of their thorax–wing system. Flapping in this manner leverages the natural elasticity of the thorax to reduce the energetic ... -
A Microfluidic-Based Investigation of Bacterial Attachment in Ureteral Stents
(2020-04)Obstructions of the ureter lumen can originate from intrinsic or extrinsic factors, such as kidney stones, tumours, or strictures. These can affect the physiological flow of urine from the kidneys to the bladder, potentially ... -
Breakpoint distance and PQ-trees
(2020-12)The PQ-tree is a fundamental data structure that has also been used in comparative genomics to model ancestral genomes with some uncertainty. To quantify the evolution between genomes represented by PQ-trees, in this paper ... -
Reconstructing embedded graphs from persistence diagrams
(2020-10)The persistence diagram (PD) is an increasingly popular topological descriptor. By encoding the size and prominence of topological features at varying scales, the PD provides important geometric and topological information ... -
Lidar measurements of the diffuse attenuation coefficient in Yellowstone Lake
(2020-03)Airborne lidar study of lake ecosystems is still a relatively unexplored field. In this paper we present measurements of the diffuse attenuation coefficient of downwelling irradiance (𝐾𝑑) obtained using a 532 nm airborne ... -
Lidar remote sensing of the aquatic environment: invited
(2020)This paper is a review of lidar remote sensing of the aquatic environment. The optical properties of seawater relevant to lidar remote sensing are described. The three main theoretical approaches to understanding the ... -
The effect of solvent polarity on autocatalytic furfural production confirmed by multivariate statistical analysis
(2019-10)Autocatalytic dehydration of xylose to furfural was studied in pure aqueous and monophasic organic/water mixtures to determine the effect reaction media and conditions have on conversion and yield. This study identified ... -
Characterization of velocity fluctuations and the transition from transient to steady state shear banding with and without pre-shear in a wormlike micelle solution under shear startup by Rheo-NMR
(2020-04)Rheo-NMR velocimetry was used to study shear banding of a 6 wt.% cetylpyridinium chloride (CPCl) worm-like micelle solution under shear startup conditions with and without pre-shear. 1D velocity profiles across the fluid ... -
Valuing Wildlife Crossings and Enhancements for Mitigation Credits
(National Academy of Sciences, 2020-01)This report summarizes the activities conducted as part of National Cooperative Highway Research Program (NCHRP) 25-25, Task 117, Valuing Wildlife Crossing and Enhancements for Mitigation Credits. Mitigation crediting could ... -
Contribution of wild foods to diet, food security, and cultural values amidst climate change
(2019-11)Wild foods are recognized to contribute to diet and food security through enhancing the availability of local, diverse, and nonmarket food sources. We investigated the contribution of wild foods to diet, food security, and ... -
Antimicrobial activity of naturally occurring phenols and derivatives against biofilm and planktonic bacteria
(2019-10)Biofilm-forming bacteria present formidable challenges across diverse settings, and there is a need for new antimicrobial agents that are both environmentally acceptable and relatively potent against microorganisms in the ... -
Nisin penetration and efficacy against Staphylococcus aureus biofilms under continuous-flow conditions
(2019-07)Biofilms may enhance the tolerance of bacterial pathogens to disinfectants, biocides and other stressors by restricting the penetration of antimicrobials into the matrix-enclosed cell aggregates, which contributes to the ... -
Janthinobacterium CG23_2: comparative genome analysis reveals enhanced environmental sensing and transcriptional regulation for adaptation to life in an Antarctic supraglacial stream
(2019-10)As many bacteria detected in Antarctic environments are neither true psychrophiles nor endemic species, their proliferation in spite of environmental extremes gives rise to genome adaptations. Janthinobacterium sp. CG23_2 ... -
DropSOAC: Stabilizing Microfluidic Drops for Time-Lapse Quantification of Single-Cell Bacterial Physiology
(2019-09)The physiological heterogeneity of cells within a microbial population imparts resilience to stresses such as antimicrobial treatments and nutrient limitation. This resilience is partially due to a subpopulation of cells ... -
Long-Term Flow through Human Intestinal Organoids with the Gut Organoid Flow Chip (GOFlowChip)
(2019-09)Human intestinal organoids (HIOs) are millimeter-scale models of the human intestinal epithelium and hold tremendous potential for advancing fundamental and applied biomedical research. HIOs resemble the native gut in that ... -
Nursing Preference for Alcohol-Based Hand Rub Volume
(Cambridge University Press (CUP), 2019-09)Background:The effectiveness of alcohol-based hand rub (ABHR) is correlated with drying time, which depends on the volume applied. Evidence suggests that there is considerable variation in the amount of ABHR used by ...
