We introduce embodied lenses for visual queries on tabletop surfaces using physical interaction. The lenses are simply thin sheets of paper or transparent foil decorated with fiducial markers, allowing them to be tracked by a diffuse illumination tabletop display. The physical affordance of these embodied lenses allow them to be overlapped, causing composition in the underlying virtual space. W...

We report on the internal ultrastructure of long, finger-like microvilli which cover the surface of the fertilized sea urchin egg. Eggs were attached to polylysine-coated surfaces; their upper portions were sheared away with a stream of buffer which left behind only their plasma membranes and adjacent cytoplasmic structures. Scanning electron microscopy (EM) of such fragments revealed intact th...

We present in this work a simple and fast preparation method of a new affinity surface-assisted laser/desorption ionization mass spectrometry (SALDI-MS) substrate based on silicon nanostructures decorated with copper particles. The silicon nanostructures were fabricated by the metal-assisted chemical etching (MACE) method. Then, superhydrophilic areas surrounded by superhydrophobic regions were...

Surfaces decorated with uniformly dispersed catalytically active nanoparticles play a key role in many fields, including renewable energy and catalysis. Typically, these structures are prepared by deposition techniques, but alternatively they could be made by growing the nanoparticles in situ directly from the (porous) backbone support. Here we demonstrate that growing nano-size phases from per...

A novel in situ method based on a liquid membrane templated self-assembly process is employed to modify carbon tube-in-tube nanostructures (TTCNTs) with Fe(2)O(3) nanoparticles. The as-obtained Fe(2)O(3) modified TTCNTs (Fe(2)O(3)/TTCNTs) nanocomposites are well constructed and the Fe(2)O(3) nanoparticles are well dispersed and decorated on the outer, inner and intramolecular surfaces of TTCNTs...

There is substantial clinical interest in synthetic platelet analogs for potential application in transfusion medicine. To this end, our research is focused on self-assembled peptide-lipid nanoconstructs that can undergo injury site-selective adhesion and subsequently promote site-directed active platelet aggregation, thus mimicking platelet's primary hemostatic actions. For injury site-selecti...

In a previous study, monoclonal antibody DS-1 was found to specifically label the decorated spongiome along the radial arms of the contractile vacuole complexes in Paramecium multimicronucleatum. Fluorescein isothiocyanate-conjugated DS-1, when injected into cells, labels the radial arms initially, but with increasing postinjection time both the intensity of fluorescence and the number of fluor...

In this paper we consider type-preserving representations of the fundamental group three-holed projective plane into Projective Linear Group $\operatorname{PGL}(2,\mathbb{R})$ and study connected components with non-maximal euler class. We show that in class zero for all such there is a simple closed curve which non-hyperbolic, while $\pm 1$ are $6$ where curves sent to hyperbolic elements $2$ ...

Abstract We study the affine schemes of modules over gentle algebras. describe smooth points these schemes, and we also analyze their irreducible components in detail. Several our results generalize formerly known results, e.g. by dropping acyclicity, incorporating band modules. A special class algebras are Jacobian arising from triangulations unpunctured marked surfaces. For obtain a bijection...
