Retrieval and recycling of synaptic vesicle membrane in pinched-off nerve terminals (synaptosomes)
The morphological features of pinched-off presynaptic nerve terminals (synaptosomes) from rat brain were examined with electron microscope techniques; in many experiments, an extracellular marked (horseradish peroxidase or colloidal thorium dioxide) was included in the incubation media. When incubated in physiological saline, most terminals appeared approximately spherical, and were filled with...
متن کاملPinched optical-vortex soliton
The fast contraction, or pinching, of optical vortices in both thermal and Kerr self-defocusing media is investigated by numerical techniques. For the thermal case, heat diffusion across the vortex core is described, and the heretofore unexplained stability of optical-vortex solitons in thermal media is explained. © 2001 Optical Society of America OCIS codes: 190.4420, 190.5940, 190.3270, 160.4...
متن کاملRegular pinched maps
This paper concerns pinched surfaces, also known as pseudosurfaces. A map is a graph G embedded on an oriented pinched surface. An arc of a map is an edge of G with a fixed direction. A regular map is one with a group of orientation-preserving automorphisms that acts regularly on the arcs of a map, i.e., that acts both freely and transitively. We study regular maps on pinched surfaces. We give ...
متن کامل-pinched Anosov Diffeomorphism and Rigidity
Let / be a C°° Anosov diffeomorphism of a compact man-ifold M, preserving a smooth measure. If / satisfies the |-pinching assumption defined below, it must preserve a continuous affine connection for which the leaves of the Anosov foliations are totally geodesic, geodesically complete, and flat (its tangential curvature is defined along individual leaves). If this connection, which is the uniqu...
متن کاملThe Pinched Veronese Is Koszul
In this paper we prove that the coordinate ring of the pinched Veronese (i.e k[X, XY, XY , Y , XZ, Y Z, XZ, Y Z, Z] ⊂ k[X, Y, Z]) is Koszul. The strategy of the proof is the following: we can consider a presentation S/I where S = k[X1, . . . , X9]. Using a distinguished weight ω, it’s enough to show that S/inωI is Koszul. We write inωI as J + H where J is generated by a Gröbner basis of quadric...
