متن کاملtaxonomic status of sand boas of the genus eryx (daudin, 1803) (serpentes: boidae) in bahr al-najaf depression, al-najaf province, iraq
five metric and 10 meristic characters were studied in 30 specimens of eryx (daudin, 1803) in bahr al-najaf depression, al-najaf province – iraq. according to the results, and considering the principle of priority, we concluded that the populations of e. jaculus (linnaeus, 1758) in the study area should be classified into e. jaculus jaculus (linnaeus, 1758) and e. jaculus familiaris echwald, 18...
متن کاملOn Boas-type Problem
R.P. Boas has found necessary and sufficient conditions of belonging of function to Lipschitz class. From his findings it turned out, that the conditions on sine and cosine coefficients for belonging of function to Lip α (0 < α < 1) are the same, but for Lip 1 are different. Later his results were generalized by many authors in the viewpoint of generalization of condition on the majorant of mod...
متن کاملMitochondrial DNA-Based phylogeography of North American rubber boas, Charina bottae (Serpentes: Boidae).
We used 783 bp of mitochondrial DNA sequences to study the phylogeography of Charina bottae (rubber boa) in western North America, with an emphasis on populations from California (U.S.A.). Maximum-parsimony and maximum-likelihood methods identified a basal divergence within C. bottae that corresponds to southern and northern segments of its current distribution. These clades coincide with the r...
متن کاملBoas' Formula and Sampling Theorem
In 1937, Boas gave a smart proof for an extension of the Bernstein theorem for trigonometric series. It is the purpose of the present note (i) to point out that a formula which Boas used in the proof is related with the Shannon sampling theorem; (ii) to present a generalized Parseval formula, which is suggested by the Boas’ formula; and (iii) to show that this provides a very smart derivation o...
