A Geographic Information System (GIS) is increasingly recognized as an effective tool for urban modeling. As a part of NASA's multidisciplinary project, this article develops GIS modeling methods of constructing measurements of urban components to monitor and model urban respiration. The first step is to create an Oracle database that stores spatially and temporally referenced measures of trace...

We formulate and study a new variant of the k-armed bandit problem, motivated by e-commerce applications. In our model, arms have (stochastic) lifetime after which they expire. In this setting an algorithm needs to continuously explore new arms, in contrast to the standard k-armed bandit model in which arms are available indefinitely and exploration is reduced once an optimal arm is identified ...

This document defines the requirements for Distributed Mobility Management (DMM) in IPv6 deployments. The traditionally hierarchical structure of cellular networks has led to deployment models which are in practice centralized. Mobility management with logically centralized mobility anchoring in current mobile networks is prone to suboptimal routing and raises scalability issues. Such centraliz...

With the convergence of fixed and mobile networks, heterogeneous networks are becoming ubiquitous. Internet giants seeing plight identity authentication. To address this issue, unified access management (UAM) was conceived. This paper provides a novel scheme, named SGX-UAM, with one-time passwords (OTPs) based on Intel software guard extensions (SGX). SGX-UAM outperforms generic UAM for providi...

Antibodies to C5a have proven to be effective in treating experimental septic primate models. A 17 amino acid peptide (ASGAPAPGPAGPLRPMF) named PepA binds to C5a and prevents complement-mediated lethal shock in rats. AcPepA harboring an acetyl group at the N-terminal alanine showed increased inhibitory activity against C5a. Cynomolgus monkeys destined to expire from a lethal dose of bacterial e...

Anthrax has been described since biblical times. It was the first disease proved to be caused by an identified bacterial agent, the Bacillus anthracis. In man, the disease occurs in a cutaneous form as a malignant pustule, in a pulmonary form as wool sorters' disease, and very rarely in an intestinal form. Although the incidence of anthrax is rare in many parts of the world, it still remains en...

The present study aimed to assess the simultaneous activities of some considered accessory muscles for respiration and search to what extent, subjects postures and forms of respiratory movements can affect the activities of these muscles in subjects positioned upright and in a supine posture. The electromyographic (EMG) study of the pectoralis major (PM), serratus anterior (SA) and external obl...

The federal government’s debt has increased dramatically in the past few years, and large annual budget deficits will probably continue indefinitely under current laws or policies. If current laws remain unchanged, deficits will total roughly $7 trillion over the next 10 years, the Congressional Budget Office (CBO) projects; if certain policies that are scheduled to expire under current law wer...

Directory-based cache coherence is a popular mechanism for chip multiprocessors and multicores. The directory protocol, however, requires multicast for invalidation messages and the collection of acknowledgement messages, which can be expensive in terms of latency and network traffic. Furthermore, the size of the directory increases with the number of cores. We present Library Cache Coherence (...

Considerable research in strategy and innovation has been devoted to examining when and how firms accumulate resources. Yet, little empirical work has focused on when firms disband resources and how this decision to disband resources is affected by firm strategy. This oversight is surprising since theoretical work has highlighted the importance of knowing which assets to grow and which assets t...
