-Y, Y loss in leukemia

Note Loss of the Y chromosome from individual metaphases is common in metaphase cells from both PHAstimulated lymphocytes and spontaneously dividing bone marrow cells. The frequency of Y loss is greater in older men, and the size of the 45,X,-Y cell population probably increases gradually with advancing age. (In females, a corollary loss of one X chromosome also occurs with advancing age.) This...

Characteristics of strained GaAs 1 − y Sb y ( 0 . 16 y 0 . 69 ) quantum wells on InP substrates

Pseudomorphic GaAs1−ySby quantum wells with 0.16 y 0.69 on (0 0 1) InP substrates have been grown using metal–organic chemical vapour deposition. High resolution x-ray diffraction and transmission electron microscopy analysis are used to quantify the layer thicknesses and compositions. Studies of the optical properties suggest that a transition from type-I to type-II band alignment occurs at an...

Connections between C(X) and C(Y), where Y is a subspace of X

In this paper, we introduce a method by which we can find a close connection between the set of prime $z$-ideals of $C(X)$ and the same of $C(Y)$, for some special subset $Y$ of $X$. For instance, if $Y=Coz(f)$ for some $fin C(X)$, then there exists a one-to-one correspondence between the set of prime $z$-ideals of $C(Y)$ and the set of prime $z$-ideals of $C(X)$ not containing $f$. Moreover, c...

$EVWUDFW Relying fully on manual effort in generating metadata is not the way to go: we need automation of this process, as much as possible, without losing the “quality” of the metadata. In this paper we report on our experiences with automatic metadata generation. We briefly outline the first version of our framework for automatic metadata generation and then report on some lessons we learned...
