Effects of fish caudal fin sweep angle and kinematics on thrust production during low-speed thunniform swimming
(The Company of Biologists, 2019-06-12)
Scombrid fish lunate caudal fins are characterized by a wide range of sweep angles. Scombrid that have small sweep-angle caudal fins move at higher swimming speeds, suggesting that smaller angles produce more thrust. ...
Age-related strength loss affects non-stepping balance recovery
(Public Library of Science, 2019-01-18)
Aging is associated with a higher risk of falls, and an impaired ability to recover balance after a postural perturbation is an important contributing factor. In turn, this impaired recovery ability likely stems from ...
Off-chip passivated-electrode, insulator-based dielectrophoresis (O pi DEP)
(Springer Heidelberg, 2013-08-01)
In this study, we report the first off-chip passivated-electrode, insulator-based dielectrophoresis microchip (OπDEP). This technique combines the sensitivity of electrode-based dielectrophoresis (eDEP) with the high ...
Aggregated responses of human mobility to severe winter storms: An empirical study
(PLOS, 2017-12-07)
Increasing frequency of extreme winter storms has resulted in costly damages and a disruptive impact on the northeastern United States. It is important to understand human mobility patterns during such storms for disaster ...
Functional compartmentalization in the hemocoel of insects
(Springer Nature, 2019-04-15)
The insect circulatory system contains an open hemocoel, in which the mechanism of hemolymph flow control is ambiguous. As a continuous fluidic structure, this cavity should exhibit pressure changes that propagate quickly. ...
Energy advantage of anode electrode rotation over anolyte recirculation for operating a tubular microbial fuel cell
(Elsevier, 2019)
Mixing plays a key role in both electricity generation and organic removal in microbial fuel cells (MFCs) via affecting substrate distribution and internal resistance. Herein, two mixing methods, anode electrode rotation ...
Mathematical Models of Localized Muscle Fatigue: Sensitivity Analysis and Assessment of Two Occupationally-Relevant Models
(PLOS, 2015-12-14)
Muscle fatigue models (MFM) have broad potential application if they can accurately predict muscle capacity and/or endurance time during the execution of diverse tasks. As an initial step toward facilitating improved MFMs, ...
Citizen Science During the Flint, Michigan Federal Water Emergency: Ethical Dilemmas and Lessons Learned
(Ubiquity Press, 2019-03-08)
A citizen science collaboration between Flint residents, the Virginia Tech “Flint Water Study” team, and others helped to uncover the Flint Lead-in-Drinking Water Crisis and a community-wide outbreak of Legionella. The ...
Numerical and experimental validation of a three-dimensional combustion diagnostic based on tomographic chemiluminescence
(Optical Society of America, 2013-03-25)
Three-dimensional (3D) measurements are highly desirable both for fundamental combustion research and practical monitoring and control of combustion systems. This work discusses a 3D diagnostic based on tomographic ...
Computational study of HIV gp120 as a target for polyanionic entry inhibitors: Exploiting the V3 loop region
(PLOS, 2018-01-18)
Multiple approaches are being utilized to develop therapeutics to treat HIV infection. One approach is designed to inhibit entry of HIV into host cells, with a target being the viral envelope glycoprotein, gp120. Polyanionic ...
