Contrary to the conventional near-field superlensing, subwavelength superlens imaging is experimentally demonstrated in the far-field. The key element is termed as a Far-field SuperLens (FSL) which consists of a conventional superlens and a nanoscale coupler. The evanescent fields from the object are enhanced and then converted into propagating fields by the FSL. By only measuring the propagati...

OBJECTIVES This study aimed to describe the criteria used by US hospitals to grant surgical privileges for select gynecologic procedures and to compare the privileging processes between university-based and community-based hospitals. METHODS We conducted a cross-sectional study from January 2011 to December 2012 that included institutions represented by Fellows' Pelvic Research Network member...

BACKGROUND There has been a growing interest in the use of volunteer clinical preceptors to provide clinical instruction to respiratory therapy (RT) students. However, many RT preceptors have had little or no training in preceptorship. We sought to identify the preceptor training needs of programs that lead to the Registered Respiratory Therapist or Certified Respiratory Therapist credential (R...

OBJECTIVE To establish a mentoring program to provide resident physicians in ophthalmology with career guidance in practice management and to identify new and creative ways to involve future eye physicians in the legislative and political process. METHODS A multicenter prospective study was conducted of the mentorship experiences of 24 (88.9%) of 27 resident physicians in Tennessee during the...

The selection of medical students in Singapore has been a contentious issue for more than 140 years. Initially, students were selected for Madras Medical College, the traditional source for medical officers in early Singapore, by a combination of an examination as well as an observed preceptorship at the General Hospital. With the establishment of the medical school in Singapore in 1905, the se...

We obtain a two-parameter set of solutions, which represents a spherically symmetric space-time with a superposition of a neutral fluid and an electric field. The electromagnetic four-potential of this Einstein-Maxwell space-time is taken in the form A = q n rdt, when n 6= 0 and A = q ln r dt, when n=0 (where q and n are arbitrary constants). Some particular solutions obtainable from the genera...

BACKGROUND Thirteen percent of newly licensed registered nurses (NLRNs) vacate their first job after 1 year, and 37% report that they feel ready to change jobs. Turnover can lead to consistent and detrimental nursing shortages in nursing units, as well as increased costs for health care systems. METHOD A descriptive, prospective, cross-sectional design was used to understand how preceptor rol...
