Multi-Channel Access has the potential to solve the throughput and scalability issues that mar the performance of 802.11 mesh and adhoc networks. It allows multiple simultaneous transmissions in a radio neighborhood thereby increasing network throughput and scalability. In spite of this potential, it is limited to simulation studies and its implementation on hardware is rare. In this demo, we d...

CONTEXT One of the goals of providing manipulative treatment such as osteopathic manipulative treatment (OMT) is to restore maximal, pain-free movement of the musculoskeletal system and to enhance neuromuscular function. Anecdotally, some athletes have reported that their athletic performance improves after manipulative treatment. OBJECTIVE To develop preliminary data to gain more understandi...

From version 2.6.22, the mac80211 framework has been incorporated as part of the stock kernel in Linux. This means millions of Linux based devices depend on this framework to provide wireless networking. The framework provides functionalities and interfaces for wireless device drivers (e.g., ath5k) to delegate common tasks to the kernel and to exchange information between physical and upper lay...

conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...

ackground: Risperidone has been shown to be clinically effective for the treatment of aggressive behavior in children, yet no information s available regarding whether risperidone exhibits aggression-specific suppression in preclinical studies that use validated developmentally mmature animal models of escalated aggression. Previously, we have shown that exposure to low doses of the psychostimu...

The poor state of security on the Internet calls for more effective ways to protect networked systems from attacks. One solution is to be able to counter attack with offensive capabilities. With attacker information available, companies find themselves in a dilemma – counter attack for immediate self-defense, retaliate for future deterrence, inform the appropriate law enforcement authorities, o...

background and objectives: day-shift taxi drivers have a long duration of direct sun exposure. however, the efficiency of this occupational exposure in vitamin d synthesis has not been addressed yet. the aim of this study was to assess the vitamin d status of taxi drivers in tehran, and examine vitamin d status association with some anthropometric and circulating biomarkers. materials and metho...

Introduction: Sleepiness may predispose drivers to road traffic accidents. Obstructive Sleep Apnea Syndrome is the most common medical cause of sleepiness. Hence increased neck circumference (NC) and obesity are known as obstructive sleep apnea syndrome risk factors. This study was conducted to assess OSAS role in occurrence of road traffic accidents in sleeping drivers of commercial heavy veh...

How does diversity affect performance? We develop a theoretical framework in which diversity of prevention employees (protecting the organization from harm) and of promotion employees (advancing positive outcomes) have different effects on individual and organizational performance. We use data for twenty-eight soccer teams and 1723 players that played in 6120 games during ten seasons and find t...

We discuss a reference model for security measures to preserve integrity of information. Unlike traditional approaches which focus on an defensive approach to preserving integrity, we also present offensive measures to stimulate integrity of information, by providing feedback from usage. The reference model is used to analyze the security measures proposed in the design of the Dutch national El...
