Higher Rank Numerical Ranges of Normal Matrices
The higher rank numerical range is closely connected to the construction of quantum error correction code for a noisy quantum channel. It is known that if a normal matrix A ∈ Mn has eigenvalues a1, . . . , an, then its higher rank numerical range Λk(A) is the intersection of convex polygons with vertices aj1 , . . . , ajn−k+1 , where 1 ≤ j1 < · · · < jn−k+1 ≤ n. In this paper, it is shown that ...

متن کاملNormal reference ranges for echocardiography: do we really need more?
Echocardiography is themostwidelyusednon-invasivecardiac imaging for assessing the cardiac structure and function. Echocardiography has the advantage of low cost, no radiation risk, and great availability. However, as for any diagnostic test, its interpretation depends on its ability to accurately detect abnormalities. Actually, the definition of ‘abnormal’ relies on the definition of ‘normal’ ...
متن کاملNew normal ranges for the radioiodine uptake study.
attached to an external detector system, the thyroid uptake of iodine was measured at 6 and 24 hr. The external detector consisted of a 1Â1⁄4x 1 in. NaI(Tl) scintillation crystal and a flat-field lead collimator. A Lucite extension of the collimator was shaped to fit the neck and assure good geometry with a neck-to crystal distance of 20 cm. A standard neck phantom was used with standard capsul...
