Adherence of Mycobacterium avium complex (MAC) to human respiratory epithelial cells (HEp-2) induced 2 distinct modes of internalization. In the first, MAC induced ruffling of HEp-2 cell membrane and formation of surface projections securing the bacilli on the surface, and concurrent membrane depressions, beneath the sites of attachment of bacilli, resulted in internalization of the organisms. ...

Keywords: MAC protocol Wireless sensor networks Fire emergency a b s t r a c t We introduce ER-MAC, a novel hybrid MAC protocol for emergency response wireless sensor networks. It tackles the most important emergency response requirements, such as autonomous switching from energy-efficient normal monitoring to emergency monitoring to cope with heavy traffic, robust adaptation to changes in the ...

Mac-1 (alphambeta2), a leukocyte adhesion receptor, has been shown in vitro to functionally interact with Fcgamma receptors to facilitate immune complex (IC)-stimulated polymorphonuclear neutrophil (PMN) functions. To investigate the relevance of Mac-1-FcgammaR interactions in IC-mediated injury in vivo, we induced a model of Fc-dependent anti-glomerular basement membrane (GBM) nephritis in wil...

INTRODUCTION The purpose of this study was to separate MAC lung disease from colonization and to define indications for treatment. MATERIALS AND METHODOLOGY Over 4 years, we evaluated patients who had positive MAC cultures, MAC infection and coinfection with MTB. In the first study, 42 immunocompetent patients with sputum or BAL culture positive only for MAC during a single year (2004) were r...

Wireless sensor networks consist of sensor nodes which are expected to be battery-powered and are hard to replace or recharge. Thus, reducing the energy consumption of sensor nodes is an important design consideration in wireless sensor networks. For the implementation of an energy-efficient MAC protocol, a Sensor-MAC based on the IEEE 802.11 protocol, which has energy efficient scheduling, has...

LWT-MAC is a new Low Power Listening MAC protocol for WSNs designed to rapidly react to instantaneous increases of the network load. It takes advantage of overhearing by waking up all nodes at the end of a transmission to send or receive packets without needing to transmit the long preamble before. In this work, detailed analytical models of the LWT-MAC and B-MAC protocols, for both saturated a...

A cryptanalysis is given of a MAC proposal presented at CRYPTO 2003 by Cary and Venkatesan. A nice feature of the CaryVenkatesan MAC is that a lower bound on its security can be proved when a certain block cipher is modelled as an ideal cipher. Our attacks find collisions for the MAC and yield MAC forgeries, both faster than a straightforward application of the birthday paradox would suggest. F...

Computer forensic tools for Apple Mac hardware have traditionally focused on low-level file system details. Mac OS X and common applications on the Mac platform provide an abundance of information about the user’s activities in configuration files, caches, and logs. We have developed Mac MarshalTM, an extensible tool suite for the analysis of files on Mac OS X disk images. Mac Marshal provides ...

There exist a lot of medium access control (MAC) protocols for wireless sensor networks. However, they consider mainly energy efficiency rather than latency which is important in delay sensitive mobile sensor networks. Therefore, a new MAC protocol called MS-MAC is proposed suitable to both stationary and mobile sensor networks. MSMAC uses an adaptive frame structure improved for well known pro...
