Pact is a parallel programming environment relieving the programmer from the burdens of parallel programming which are not really necessary to write efficient parallel programs. This is done by providing a simple synchronization model and virtual shared data with user-defined granularity and automatic consistency control. Pact guarantees user-transparent fault-tolerance with low overhead by usi...

Few recent stories about teen pregnancy have been so compelling as the item that surfaced in June 2008 in Time magazine, and was then zoomed around the world’s media post haste. The location is Gloucester, Massachusetts – America’s oldest seaport. The venue is Gloucester High School. The protagonists are a 17-strong group of girls, aged 14–16 years, who over the past calendar year have become p...

Abstract In the years after First World War, a worrying legal and cultural phenomenon appeared in English criminal court, something that would captivate reading public throughout Britain. Young people, specifically young couples, were agreeing to die together, what become known as ‘suicide pact’. This article examines curiously brief life of suicide pact legal, social, problem It contends becam...

Dendritic spines cut loose to mature D eveloping dendritic spines need to hold on tight to the extracellular matrix as they seek out partnering neurons. Once they fi nd partners, however, the spine tips must sever their matrix ties to reshape into post-synaptic receiving stations, according to Tian et al. (page 687). Dendritic spine growth and maturation coincides with the expression of a neuro...

The story of the Pact of unity between Chiara Lubich and Igino Giordani, which was the prelude to Chiara’s mystical experience in the summer of 1949, concludes with the introduction of something new arising from the Pact: the Soul. Chiara describes it as “the bond between us,” the “space” where the multiplication of the one and the unification of the many is both actualized and explained. This ...

This paper addresses actuator outages, or any actuator fault under the reconfiguration strategy. Based on the lattice structure of the set of system configurations, the concept of an extensive control law is introduced and shown to allow the design of a fault tolerant control strategy that mixes the passive and active approaches (PACT strategy). Extensive controls for α-stability and quadratic ...

Using internal illumination with an optical fiber in the oral cavity, we demonstrate, for the first time, photoacoustic computed tomography (PACT) of the deep brain of rats in vivo. The experiment was performed on a full-ring-array PACT system, with the capability of providing high-speed cross-sectional imaging of the brain. Compared with external illumination through the cranial skull, interna...
