Low Temperature Properties of Anisotropic Superconductors with Kondo Impurities
We present a self-consistent theory of superconductors in the presence of
Kondo impurities, using large- slave-boson methods to treat the impurity
dynamics. The technique is tested on the s-wave case and shown to give good
results compared to other methods for . We calculate low temperature
thermodynamic and transport properties for various superconducting states,
including isotropic s-wave and representative anisotropic model states with
line and point nodes on the Fermi surface.Comment: 21 pages, RevTeX 3.0, 12 figures available upon request, UF preprin

The major histocompatibility complex-restricted antigen receptor on T cells: the genetics of expression of an allotype.
The monoclonal antibody KJ16-133 binds an allelic determinant expressed on the antigen-specific, major histocompatibility complex (MHC)-restricted receptors on approximately 20% of T cells in most mouse strains. The locus controlling the presence or absence of the determinant mapped 9.8 +/- 2.2 centimorgans f}irom the Igk/Ly-2 locus on chromosome 6 in mice, and may be the beta-chain locus. Other genetic loci were identified that controlled the frequency of cells that expressed the allele in positive mice. One of these was the MHC itself, which may control expression of the beta-chain allele by controlling T cell repertoire. The identity of the other, as yet unmapped locus is unknown. KJ16-133 was used to show that T cell receptor gene products are expressed in a manner consistent with allelic exclusion
Utility of the routine chest X-ray after over-wire venous catheter changes.
The Seldinger technique is commonly used to change central venous access catheters in the Intensive Care Unit. These catheters are routinely being changed to prevent septic complications. Some of these changes are performed by an over-wire technique. To assess the utility of postprocedural chest X-rays on critically ill patients after an over-wire catheter change, we followed 68 patients after they had 80 catheter changes. This study assesses catheter position by use of a postprocedural X-ray. During the study, we found no misplaced catheters and minimum symptomatology in 80 patients. The trauma/critical care fellows performing the procedures rated them as easy in 97.5 percent of the changes. The conclusion of the study is that, if the catheter change is technically easy and the patient has no symptoms, a postprocedural X-ray is not necessary
