In the Time Warp (TW) protocol, the system state must be checkpointed to facilitate the rollback operation. While increasing the checkpointing frequency increases the state saving cost, an infrequent scheme also escalates the coast forward eeort when a large number of executed events are redone. This paper proposes a prob-abilistic approach to checkpointing. We derive the roll-back probability,...

Three new species of calcareous sponges from the coast of Bahia State, NE Brazil are described. All of them belong to the genus Paraleucilla (Calcaronea, Leucosolenida, Amphoriscidae): P. solangeae sp. nov., P. oca sp. nov., and P. incomposita sp. nov. The number of species recorded from the Bahia coast has thus increased from 10 to 13. Including these new species, there are now 50 calcareous s...

We appreciate the opportunity to testify on the Deepwater Capability Replacement Project, which was initiated by the Coast Guard to replace and modernize its aging fleet of over 90 cutters and 200 aircraft used beyond 50 miles from shore. This project, the largest acquisition ever attempted by the Coast Guard, will likely cost over $10 billion or more and will not be completed for 2 to 3 decade...

The decapod crustaceans of the Gulf of Oman have been documented based on the published literature and new sampling along the Iranian coast between 2005 and 2015. A total of 121 species were collected along the Iranian coast, of which 43 are new records for the Gulf of Oman. The Decapoda of the Gulf is currently represented by 258 species belonging to five infraorders: Axiidea, Achelata, Anomur...

A team of 10 researchers from the Coast Guard Research and Development Center, University of Southern California, and University of Chile were recognized April 8, 2013, as the recipients of the 2012 Daniel H. Wagner Prize for Excellence in Operations Research Practice at the annual Institute for Operations Research and the Management Science (INFORMS) Analytics Conference in San Antonio. The Co...

The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

In this study graphene oxide (GO) was synthesized by using Hummer’s method. Low dimension graphene quantum dot nanoparticles (GQDs) were synthesized using pulse laser irradiation. Fourier Transform-Infrared Spectroscopy (FTIR), Ultraviolet-Visible (UV-Vis) spectroscopy and photoluminescence (PL) analysis were applied to study the GQDs characteristic. Scanning electron microscopy illustrated the...

Introduction Familial Mediterranean Fever (FMF) is an ethnic disease for Armenian population and represents a significant health care problem. Frequency of carriers of MEFV mutations is 1:3, and the prevalence of FMF is rather high (14-100:10000). During the period between 2003 and 2012 there was a 4.5-fold increase of the total number of children with FMF. Many of these cases have severe clini...
