Acquired Mls-1a-like clonal deletion in Mls-1b mice
BALB/c mice (H-2d, Mls-1b) from one colony progressively modify their T cell repertoire during aging, by deleting T cells that express products of the V beta 6 and V beta 8.1 genes of the T cell receptor. Clonal deletion occurs only in 50% of mice between 27 and 43 wk of age, affecting thymus, spleen, and lymph node T cells. The phenomenon is progressive and seems to affect nearly all thymuses ...
متن کاملOut-of-core Mls Reconstruction
The accurate and robust reconstruction of a digital representation using 3D scanning technologies is an important task in many application field. An important problem in this field is the integration of multiple range maps in a single polygonal surface. In this paper we describe a robust and effective implementation of a reconstruction algorithm based on implicit representation which, thanks to...
متن کاملDual Bases and Discrete Reproducing Kernels: A Unified Framework for RBF and MLS Approximation
Moving least squares (MLS) and radial basis function (RBF) methods play a central role in multivariate approximation theory. In this paper we provide a unified framework for both RBF and MLS approximation. This framework turns out to be a linearly constrained quadratic minimization problem. We show that RBF approximation can be considered as a special case of MLS approximation. This sheds new l...
متن کاملMLS DBMS Interoperability Study
Interoperability among heterogeneous databases is a fundamental requirement of many emerging Department of Defense (DoD) systems. Often these systems also have requirements for Multilevel-Secure (MLS) operation, where data is labeled to reflect its sensitivity level (e.g., UNCLASSIFIED, SECRET, etc.). The Air Force Rome Laboratory MLS Database Management System (DBMS) Interoperability Study has...
