INTRODUCTION Medical students have been attending rural clinical schools (RCSs) since 2001. Although there have been generally positive single institution reports, there has been no multi-institution study using a common survey instrument. The experiences of medical students who attended a number of RCSs during 2006 were evaluated using a rural-specific questionnaire. METHODS Questionnaires w...

1) Target recognition via radar cross section (RCS) profiles: In this approach, databases of the RCS of targets at different incident and observed angles are created using method-of-moments computational electromagnetics codes. The extracted RCS profiles for different targets, scaled to account for antenna patterns and atmospheric propagation, are compared to the collected data. A coordinated f...

tsimpli and dimitrakopoulou (2007) observed that uninterpretable features are unavailable in second language (l2) acquisition after the critical period. in this paper, we verify this claim by providing evidence from persian speaking learners of english as an l2 on the status of resumptive pronouns (rps) as uniterpretable features. unlike english which does not allow rps, persian shows various b...

This paper focuses on the reduction of radar cross section (RCS) for a cavity embedded in an infinite ground plane. By introducing a transparent boundary condition, the unbounded scattering problem is reduced to a bounded domain problem. RCS reduction for the cavity is formulated as a shape optimization problem involving the Helmholtz equation. The existence of the minimizer is proved under an ...

BACKGROUND Australian Rural Clinical School (RCS) programmes have been designed to create experiences that positively influence graduates to choose rural medical careers. Rural career intent is a categorical evaluation measure and has been used to assess the Australian RCS model. Predictors for rural medical career intent have been associated with extrinsic values such as students with a rural ...

Hiding from and surprising an opponent are tactics that have been used in warfare throughout history. They were features that aircraft originally possessed when they were first used in military operations. However, development of military technology is an endless struggle between advances in technology and counter technology. During World War II this struggle led to the development of a new tec...

A novel broadband and wide-angle 2-bit coding metasurface for radar cross section (RCS) reduction is proposed and characterized at terahertz (THz) frequencies. The ultrathin metasurface is composed of four digital elements based on a metallic double cross line structure. The reflection phase difference of neighboring elements is approximately 90° over a broadband THz frequency. The mechanism of...

In this paper, we show how 4D/RCS incorporates and integrates multiple types of disparate knowledge representation techniques into a common, unifying architecture. 4D/RCS is based on the supposition that different knowledge representation techniques offer different advantages, and 4D/RCS is designed in such a way as to combine the strengths of all of these techniques into a common unifying arch...

This paper presents a theory of the radar cross section (RCS) of objects in multiple scattering random media. The general formulation includes the fourthorder moments including the correlation between the forward and the backward waves. The fourth moments are reduced to the second-order moments by using the circular complex Gaussian assumption. The stochastic Green’s functions are expressed in ...

PURPOSE To test wireless resonance circuits (RC) to be used as fiducial marker of endovascular catheters during MR-guided interventions. Current markers loose their signal enhancement for certain catheter orientations. The purpose of this study was to test a marker setup which overcomes this orientation problem. MATERIALS AND METHODS The markers were constructed from a pair of two RCs. The RC...
