Microswimmer Propulsion by Two Steadily Rotating Helical Flagella
(MDPI, 2019-01-01)Many theoretical studies of bacterial locomotion adopt a simple model for the organism consisting of a spheroidal cell body and a single corkscrew-shaped flagellum that rotates to propel the body forward. Motivated by ... -
The effects of flagellar hook compliance on motility of monotrichous bacteria: A modeling study
(AIP Publishing, 2012-06)A crucial structure in the motility of flagellated bacteria is the hook, which connects the flagellum filament to the motor in the cell body. Early mathematical models of swimming bacteria assume that the helically shaped ... -
Harnessing surface-bound enzymatic reactions to organize microcapsules in solution
(American Association for the Advancement of Science (AAAS), 2016-03)By developing new computational models, we examine how enzymatic reactions on an underlying surface can be harnessed to direct the motion and organization of reagent-laden microcapsules in a fluid-filled microchannel. In ... -
Harnessing catalytic pumps for directional delivery of microparticles in microchambers
(Springer Nature, 2017-02-17)The directed transport of microparticles in microfluidic devices is vital for efficient bioassays and fabrication of complex microstructures. There remains, however, a need for methods to propel and steer microscopic cargo ... -
Convective flow reversal in self-powered enzyme micropumps
(Proceedings of the National Academy of Sciences, 2016-02-22)Surface-bound enzymes can act as pumps that drive large-scale fluid flows in the presence of their substrates or promoters. Thus, enzymatic catalysis can be harnessed for "on demand" pumping in nano-and microfluidic devices ... -
Synthetic quorum sensing in model microcapsule colonies
(Proceedings of the National Academy of Sciences, 2017-07-24)Biological quorum sensing refers to the ability of cells to gauge their population density and collectively initiate a new behavior once a critical density is reached. Designing synthetic materials systems that exhibit ... -
Fluid-present anatexis of Neoarchean tonalite and amphibolite in the Western Shandong Province
(Elsevier, 2019-02)Metatonalite and amphibolite from the Taishan region of the Western Shandong Province in the North China Craton record c. 2.60 Ga fluid-present partial melting via the breakdown of biotite, plagioclase and quartz to produce ... -
Efficient treatment of climate data uncertainty in ensemble Kalman filter (EnKF) based on an existing historical climate ensemble dataset
(Elsevier, 2019-01)Successful data assimilation depends on the accurate estimation of forcing data uncertainty. Forcing data uncertainty is typically estimated based on statistical error models. In practice, the hyper-parameters of statistical ... -
Optimal investment-reinsurance strategies with state dependent risk aversion and VaR constraints in correlated markets
(Elsevier, 2019-03)In this paper, we investigate the optimal time-consistent investment–reinsurance strategies for an insurer with state dependent risk aversion and Value-at-Risk (VaR) constraints. The insurer can purchase proportional ... -
Simulations for three-dimensional landmine detonation using the SPH method
(Elsevier, 2019-04)The simulation of the soil fragmentation under buried explosive detonation is an extremely difficult task. In this paper, the modified smoothed particle hydrodynamics method (SPH) in combination with the elastoplastic and ... -
Study on fatigue life of bend-twist coupling wind turbine blade based on anisotropic beam model and stress-based fatigue analysis method
(Elsevier, 2019-01-15)Bend-twist coupling (BTC), also called aeroelastic tailoring or passive pitch control method, is often utilized to reduce the fatigue loading on wind turbine blades. With BTC, the blade can twist as it bends, this alleviates ... -
Dual network extraction algorithm to investigate multiple transport processes in porous materials: Image-based modeling of pore and grain scale processes
(Elsevier, 2019-04-06)Image processing of 3D tomographic images to extract structural information of porous materials has become extremely important in porous media research with the commoditization of x-ray tomography equipment to the lab ... -
The modulation of leguminous plant ethylene levels by symbiotic rhizobia played a role in the evolution of the nodulation process
(Elsevier, 2018-12)Ethylene plays an important role in regulating the rhizobial nodulation process. Consequently, numerous strains of rhizobia possess the ability to decrease plant ethylene levels by the expression of the enzyme 1-aminocyc ... -
Budget-constrained optimal insurance without the nonnegativity constraint on indemnities
(Elsevier, 2019-01)In a problem of Pareto-efficient insurance contracting (bilateral risk sharing) with expected-utility preferences, Gollier (1987) relaxes the nonnegativity constraint on indemnities and argues that the existence of a ... -
Flexible Energy Storage Systems Based on Electrically Conductive Hydrogels
(Elsevier, 2019-01)To power wearable electronic devices, various flexible energy storage systems have been designed to work in consecutive bending, stretching and even twisting conditions. Supercapacitors and batteries have been considered ... -
Comparing functional dynamic normalization methods to maximal voluntary isometric contractions for lower limb EMG from walking, cycling and running
(Elsevier, 2019-02)There is no consensus on the most appropriate method for normalizing an individual’s electromyography (EMG) signals from walking, cycling and running in the same data collection. The aim of this study was to compare how ... -
Arm posture influences on regional supraspinatus and infraspinatus activation in isometric arm elevation efforts
(Elsevier, 2019-02)This study aimed to evaluate the effect of arm posture on activation of the anterior and posterior regions of supraspinatus and the superior and middle regions of infraspinatus during resisted isometric arm elevations. ... -
Utilizing UV-LED pulse width modulation on TiO2 advanced oxidation processes to enhance the decomposition efficiency of pharmaceutical micropollutants
(Elsevier, 2019-04-01)The presence of pharmaceutical and personal care products (PPCPs) in aquatic systems has been a growing cause for concern. Advanced oxidation processes such as UV/TiO2 (ultraviolet light/titanium dioxide) can break down ... -
Veterans and military masculinity in popular romance fiction
(Taylor & Francis, 2018)Although popular culture has become an important area of study in international relations, few scholars so far have turned their attention to popular romance fiction, despite its popularity among readers. Through an analysis ... -
NATO’s Out of Area Norm from Suez to Afghanistan
(Taylor & Francis, 2010)The Atlantic community shares more than just dependable expectations of peaceful change. Its members also share a reflexive political community they sense is worth preserving and a view that their security is intertwined. ...
