Lamport’s Happened-before relation is fundamental to coordinating actions in asynchronous systems. Its role is less dominant in synchronous systems, in which bounds are available on transmission times over channels. This paper initiates a study of the role that time bounds play in synchronous systems by focusing on two classes of problems: Ordered Response, in which a triggering event must be f...

INTRODUCTION The chemical industry is a much safer place to work than many industries with fewer inherent hazards. Nevertheless, almost all the accidents that have occurred need not have occurred. Most of them have happened before and have been described in published reports. Someone knew how to prevent them even if the people on the job at the time did not. There is something seriously wrong w...

This study assesses the public health functions played by news information and social capital in the context of Hurricane Katrina. In-depth interviews were conducted with 57 hurricane shelter residents between 4 and 6 weeks after the hurricane. Depression was more common for participants who relied more on news information than for other participants after the hurricane (adjusted odds ratio [AO...

Irma was a major hurricane that developed during the 2017 season. It category 5 on Saffir–Simpson Hurricane wind scale. This caused severe damage in Caribbean area and Florida Keys. The social, economic, environmental impacts, mainly related to coastal flooding, were also significant Cuba. maximum limits of flooding by this determined research. Field trips use GPS supported our work, which focu...

OBJECTIVE To examine the impact of Hurricane Katrina on the health of individuals with diabetes. RESEARCH DESIGN AND METHODS This was an observational study in 1,795 adults with an A1C measurement 6 months before and 6-16 months after Hurricane Katrina in three health care systems: private (Tulane University Hospital and Clinic [TUHC]), state (Medical Center of Louisiana at New Orleans [MCLNO...

On October 29, 2012, Hurricane Sandy (Sandy) made landfall in densely populated areas of New York, New Jersey, and Connecticut. Flooding affected 51 square miles (132 square kilometers) of New York City (NYC) and resulted in 43 deaths, many caused by drowning in the home, along with numerous storm-related injuries. Thousands of those affected were survivors of the World Trade Center (WTC) disas...

Hurricanes are large-scale disturbances with the potential to exert extensive damage in coastal ecosystems. On August 29, 2005 Hurricane Katrina catastrophically impacted a large area of the Gulf of Mexico spreading from coastal Alabama to Louisiana. For five months before hurricane landfall we were assessing the structure and functioning of a mixed seagrass bed located in an area greatly affec...

Meteorological disturbances, such as hurricanes, can cause wide distributional changes to fish populations, but studies documenting movement in response these disturbances are rare and serendipitous. We opportunistically examined how a hurricane influenced behavior of Red Snapper Lutjanus campechanus at an artificial reef complex the western Gulf Mexico. had variety responses, with some emigrat...

Hurricane winds can have large impacts on forest structure and dynamics. To date, most evaluations of hurricane impacts have focused on short-term responses after a hurricane, often lacked pre-hurricane measurements, and missed responses occurring over longer time scales. Here, we use a long-term data set (1974–2009, 35 years) of tree stems (.3 cm in diameter at 1.3 m aboveground) in four sites...
