A Comparative Study of Endoscopic versus Microscopic Cartilage Type I Tympanoplasty
Introduction The use of endoscope is rapidly increasing in otological and neuro-otological surgery in the last 2 decades. Middle ear surgeries, including tympanoplasty, have increasingly utilized endoscopes as an adjunct to or as a replacement for the ...

A $q$-microscope for supercongruences [PDF]
By examining asymptotic behavior of certain infinite basic ($q$-) hypergeometric sums at roots of unity (that is, at a "$q$-microscopic" level) we prove polynomial congruences for their truncations. The latter reduce to non-trivial (super)congruences for
