Enhanced mixing and spatial instability in concentrated bacterial suspensions.
High-resolution optical coherence tomography is used to study the onset of a large-scale convective motion in free-standing thin films of adjustable thickness containing suspensions of swimming aerobic bacteria. Clear evidence is found that beyond a threshold film thickness there exists a transition from quasi-two-dimensional collective swimming to three-dimensional turbulent behavior. The latt...
متن کاملYielding and flow of highly concentrated, few-layer graphene suspensions.
For a wide range of applications of graphene suspensions, a thorough understanding of their rheological properties is crucial. We probe the microstructure of dense suspensions of micron-sized, few-layer, defect-free graphene platelets by measuring their viscoelastic properties at various concentrations up to 39 mg ml(-1). We propose a model to relate the yield strain to the mesh size of the mic...
متن کاملOperating System Protection for Fine-Grained Programs
We present an operating system-level security model for controlling ne-grained programs, such as downloaded executable content, and compare this security model's implementation to that of language-based security models. Language-based security has wellknown limitations, such as the lack of complete mediation (e.g., for compiled programs or race condition attacks) and faulty self-protection (e e...
متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملArrayTrack: A Fine-Grained Indoor Location System
Location systems are key to a rich experience for mobile users. When they roam outdoors, mobiles can usually count on a clear GPS signal for an accurate location, but indoors, GPS usually fades, and so up until recently, mobiles have had to rely mainly on rather coarse grained signal strength readings for location. What has changed this status quo is the recent trend of dramatically increasing ...
