Our strange fellowship

Characterization of reproductive endocrinology and infertility (REI) fellowship applicants: guiding our mentees toward success

Background Advanced subspecialty training in reproductive endocrinology and infertility (REI) entails a competitive application process with many data points considered. It is not known what components weigh more heavily for applicants. Thus, we sought to study the REI fellow applicant and compare 1) those who apply but do not receive an interview, 2) those who receive an interview but do not m...

Hand Surgery Fellowship Selection Criteria: A National Fellowship Director Survey

BACKGROUND Candidate characteristics for hand surgery fellowship training remains unknown, as very little data is available in the literature. This study aims to provide information on the criteria that are employed to select candidates for the hand surgery fellowship match. METHODS A 38-question survey was sent in April 2015 to all Accreditation Council for Graduate Medical Education recogni...

Family medicine obstetrics fellowship graduates: training and post-fellowship experience.

BACKGROUND AND OBJECTIVES Family medicine obstetrics and maternal-child health fellowships offer family physicians additional training in pregnancy care. Our objectives were to assess the content of these fellowship programs, the clinical practices of fellowship graduates, and factors associated with inclusion of cesarean delivery in practice after fellowship training. METHODS A survey was se...

How strange a non-strange heavy baryon?

We give some general arguments in favor of the large magnitude of matrix elements of an operator associated with nonvalence quarks in heavy hadrons. We estimate matrix element 1 2mΛb 〈Λb|s̄s|Λb〉 ≃ 1 ÷ 2 for Λb baryon whose valence content is b, u, d quarks. This magnitude corresponds to a noticeable contribution of the strange quark into the heavy baryon mass 1 2mΛb 〈Λb|mss̄s|Λb〉 ≃ 200 ÷ 300MeV ....
