Good's syndrome is a relatively rare immunodeficiency condition that presents in the fourth or fifth decade of life and is defined by hypogammaglobulinemia in the setting of a thymoma. The humoral defect may be severe enough to cause an absence in B cells, with a consequent recurrence of sinopulmonary disease, chronic non-infectious diarrhea and opportunistic infections. The prognosis in patien...

We describe JAX, a domain-specific tracing JIT compiler for generating high-performance accelerator code from pure Python and Numpy machine learning programs. JAX uses the XLA compiler infrastructure to generate optimized code for the program subroutines that are most favorable for acceleration, and these optimized subroutines can be called and orchestrated by arbitrary Python. Because the syst...

The standing spin wave resonance has been measured in thin films of EuS at 1.1 OK in the perpendiculai configuration. The magnon dispersion relation is found to be quadratic in the observed region of k (k < 0.2 xla). The effective exchange energy (JI $. Jz) determined is 0.088 f 0.010 OK. This value is lower than that calculated by Passenheim et al. [7] from specific heat measurements. This dis...

We have studied the complex interrelationships between platelets, Factor XIa, a1-protease inhibitor and Factor IX activation. Platelets were shown to secrete an inhibitor of Factor XMa, and to protect Factor XIa from inactivation in the presence of a1-protease inhibitor and the secreted platelet inhibitor. This protection of Factor Ma did not arise from the binding of Factor XIa to platelets, t...

Loss of function of Bruton's tyrosine kinase (Btk) causes X-linked agammaglobulinemia (XLA) in humans and X-linked immunodeficiency in mice (xid). By using MS analysis and phosphopeptide-specific antibodies, we identified a tyrosine phosphorylation site (Y617) near the carboxyl terminus of the Btk domain from Btk expressed in 293T as well as DT-40 cells. Y617 is conserved in all Tec family kina...

A complete range of perovskite solid solutions can be formed in the (1 − x)Ba(Mg1/3Nb2/3)O3–xLa(Mg2/3Nb1/3)O3 (BMN–LMN) pseudobinary system. While pure BMN adopts a 1:2 cation ordered structure, 1:1 ordered phases are stabilized for 0.05 ≤ x ≤ 1.0. Dark-field TEM images indicate that the La-doped solid solutions are comprised of large 1:1 ordered domains and no evidence was found for a phase-se...
