Cone-guided fast ignition laser fusion depends critically on details of the interaction of an intense laser pulse with the inside tip of a cone. Generation of relativistic electrons in the laser plasma interaction (LPI) with a gold cone and their subsequent transport into a copper wire have been studied using a kJ-class 9 Current address: Osaka University, Osaka 565-0871, Japan. 10 Author to wh...
A new cathode for cold-field emission gun using a pyrolytic carbon-cone supported onto a carbon nanotube as the electron emitting tip has been developped. This tip was mounted in a TEM using a FIB based method, and the brightness measured under real operating conditions is 5 times better than obtained with a standard tungsten tip. Its use overcomes the many technical difficulties which have dog...
The establishment of neuronal connections during embryonic development requires the precise guidance and targeting of the neuronal growth cone, an expanded cellular structure at the leading tip of a growing axon. The growth cone contains sophisticated signaling systems that allow the rapid communication between guidance receptors and the actin cytoskeleton in generating directed motility. Previ...
In this article, we shall construct the resolvent of Laplacian at high energies near spectrum on non-product conic manifolds with a single cone tip. Microlocally, kernel is sum b-pseudodifferential operators, scattering pseudodifferential operators and intersecting Legendrian distributions. As an application, establish Strichartz estimates for Schrödinger equations non-compact multiple singular...
Kelvin probe force microscopy (KPFM) is a widely used technique to measure the local contact potential difference (CPD) between an AFM probe and the sample surface via the electrostatic force. The spatial resolution of KPFM is intrinsically limited by the long range of the electrostatic interaction, which includes contributions from the macroscopic cantilever and the conical tip. Here, we prese...
TCV (Turnip crinkle virus) coat protein is required for the resistance response in Arabidopsis thaliana Di-17 plants. An aspartate→asparagine mutation at amino acid four of the coat protein is sufficient to result in resistance-breaking. To determine the essential chemical properties responsible for the induction of resistance, a series of site-directed mutants were produced. Serine as well as ...
Some physicists suggest that to more adequately describe the causal structure of space-time, it is necessary to go beyond the usual pseudoRiemannian causality, to a more general Finsler causality. In this general case, the set of all the events which can be influenced by a given event is, locally, a generic convex cone, and not necessarily a pseudoReimannian-style quadratic cone. Since all curr...
In this work we provide a basic physical modeling of the spatiotemporal pattern of emulsification produced by chemical reaction-driven tip-streaming and observed by Fernandez and Homsy @Phys. Fluids 16, 2548 ~2004!#. Features of this phenomenon—nonlinear autooscillations, a conical drop shape, tip-streaming, and droplet trajectory splitting—are addressed in this paper. In particular, the experi...
Atomic force microscope with applicable types of operation in a liquid environment is widely used to scan the contours of biological specimens. The contact mode of operation allows a tip to touch a specimen directly but sometimes it damages the specimen; thus, a tapping mode of operation may replace the contact mode. The tapping mode triggers the cantilever of the microscope approximately at re...
