Point of contact (POC) is the main element for managing a positive image of any company or brand. Obviously, any large firm can’t interact with its sole customers directly. Yet, they require a channel through which they can deliver all kinds of information or handle any infringements with ...
An image displayed on a touchscreen is varied (re-sized) according to the size of a point of contact made by a user (using a stylus or digit i.e. finger or thumb) on the screen. For example, the size 28 of an icon (e.g. a button) displayed on the touch screen may be ...

InFig. 9the image of a point source (small electric dipole) is plotted through a flatland version of a transmission-line Veselago-Pendry lens37–38. Note that the brightest spot lies at the exit interface of the lens and along the line that joins the source and the image. On the other...
The Point Cloud Library (PCL) is a standalone, large scale, open project for 2D/3D image and point cloud processing. PCL is released under the terms of the BSD license, and thus free for commercial and research use. We are financially supported by a consortium of commercial companies, with...
Using the Mehler-Fock transformation to solve Poisson's equation in prolate spheroidal coordinates, we have obtained an exact Green's function solution for all multiple image corrections to the vacuum tunneling barrier for a hyperboloidal tip-planar-anode model of a point-contact junction consisting ...

In a previous paper (Avotina et al.,Phys. Rev. B Vol.71, 115430 (2005)) we have shown that in principle it is possible to image the defect positions below a metal surface by means of a scanning tunnelling microscope. The principle relies on the interference of electron waves scattered ...
Graphene field effect transistor (FET) biosensors have attracted huge attention in the point-of-care and accurate detection. With the recent spread of the new emerging severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the need for rapid, and
