In recent years, unmanned aerial vehicles (UAVs) have become the trend for different types of research and applications. UAVs can accomplish some technical risky tasks while still being safe, mobile, inexpensive to operate. However, need flying ad-hoc networks (FANET) operate in inaccessible or infrastructure-less areas. Subsequently, many military civil applications, are connected ad hoc. FANE...

A classical action for open superstring field theory has been proposed which does not suffer from contact term problems. After generalizing this action to include the non-GSO projected states of the Neveu-Schwarz string, the pure tachyon contribution to the tachyon potential is explicitly computed. The potential has a minimum of V = −

this article is intended to provide an overview of various aspects of clinical pet/ct. these include discussions of: (i) important areas of clinical application; (ii) opportunities in clinical research; (iii) scanner and operating-mode considerations (e.g. bgo vs. lso, lyso or gso scanners, 2d vs. 3d imaging). (iv) study-specific considerations (e.g. patient preparation and positioning issues, ...

Background and objective: Nurses who return to school obtain higher education come with varying levels of professional, educational technological competencies. Some are new graduates, others have not been in for a decade, several find technology difficult navigate. Returning can be challenging because graduate programs require complex skills order students succeed. Onboarding, the process organ...

From the string partition function, we discuss the mass-shell and GSO projection conditions valid for KaluzaKlein (KK) as well as massless states in the heterotic string theory compactified on a nonprime orbifold. Using the obtained conditions we construct a 4D string standard model, which is embedded in a 6D SUSY GUT by including KK states above the compactification scale. We discuss the strin...

We show how the spectral flow between the Neveu-Schwarz and Ramond sectors of N = 2 superconformal field theories can be described in three dimensions in terms of the propagation of charged particles coupled to a a ChernSimons gauge theory. Quantum mechanical mixing between the degenerate Chern-Simons vacua interpolates between the different boundary conditions of the two sectors and so provide...
