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 ...

Descriptive statistics for the Neonatal Intensive Care Unit Network Neurobehavioral Scale summary scores are provided based on data from 1388 1-month-old infants in the Maternal Lifestyle Study (MLS) of prenatal drug exposure and child outcome. The multisite MLS is described, followed by tables with descriptive statistics and percentile for the Neonatal Intensive Care Unit Network Neurobehavior...

Superlattices consisting of As monolayers ~MLs! in ~In,Ga,Al!Sb and Sb MLs in ~In,Ga,Al!As were grown by molecular beam epitaxy and characterized by x-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy. In all cases, well-defined superlattices were formed when the growth temperature was sufficiently low. As temperature increases for the As MLs in antimonid...

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...

Superantigen bound to major histocompatibility complex (MHC) products have been shown to stimulate T cells in a V beta-specific manner. Mouse T cells bearing V beta 8.1 usually respond to the self superantigen, Mls-1a, whereas T cells bearing V beta 8.2a do not. Previously, using site-directed mutational analysis, we identified the residues of natural variants of T cell receptor (TCR) V beta 8....

Multilevel societies (MLS), in which polygynous reproductive units are nested in a larger social matrix, represent a highly complex social system documented only in a small number of mammalian species. Using long-term behavioural data, satellite telemetry and social network analysis, we present a new framework for understanding the function and social dynamics of the golden snub-nosed monkey ML...

Extracting ground surface from high-density point clouds collected by Mobile Laser Scanning (MLS) systems is of vital importance in urban planning and digital city mapping. This article proposes a novel approach for automated extraction of ground surface along urban roads from MLS point clouds. The approach, which was designed to handle both ordered and unordered MLS point clouds, consists of t...

Thermal transport in multilayers (MLs) has attracted significant interest and shows promising applications. Unlike their single-component counterparts, MLs exhibit a thermal conductivity that can be effectively engineered by both the number density of the layers and the interfacial thermal resistance between layers, with the latter being highly tunable via the contrast of acoustic properties of...

DOD Joint Vision 2020 (JV2020) is the integrated multi-service planning document for conduct among coalition forces of future warfare. It requires the confluence of a number of key avionics technical developments: integrating the network-centric battlefield, management of hundred thousands of distributed processors, high assurance Multi Level Security (MLS) in the battlefield, and low cost high...
