determinant of the hankel matrix with binomial entries
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.
15 صفحه اولDiagnostic accuracy of the Matrix 24-2 and original N-30 frequency-doubling technology tests compared with standard automated perimetry.
PURPOSE To compare the diagnostic accuracy of the Matrix frequency-doubling technology (FDT) 24-2, first-generation FDT N-30 (FDT N-30), and standard automated perimetry (SAP) tests of visual function. METHODS One eye of each of 85 glaucoma patients and 81 healthy controls from the Diagnostic Innovations in Glaucoma Study was included. Evidence of glaucomatous optic neuropathy on stereophotog...
متن کاملLarge N Matrix Field Theories
We discuss aspects of recent novel approaches towards understanding the large N limit of matrix field theories with local or global non-abelian symmetry. The large N limit of field theories whose local degrees of freedom are N ×N matrices continues to intrigue physicists since its discovery by ‘t Hooft 25 years ago [1]. This is striking given the fact that no field theory with propagating matri...

programmed, then this implies that definite molecular alterations on the level of transcription or translation should be observable, and furthermore, it should be possible (theoretically at least) to accelerate, decelerate, or even reverse these events by the appropriate manipulation of molecular events. Furthermore, we would expect that naturally-occurring mutations may occasionally hit upon s...
متن کاملComparison of contrast sensitivity, visual acuity, and Humphrey visual field testing in patients with glaucoma.
BACKGROUND Despite their normal or near-normal Snellen visual acuity, patients with glaucoma often complain of "poor" vision. OBJECTIVE To investigate the relationship between large-letter contrast sensitivity, high-contrast visual acuity, and visual field defects in patients with glaucoma who have 20/40 or better visual acuity. DESIGN Prospective, cross-sectional case series. PATIENTS AN...
