The beam dump is a critical component for the in-flight fragment separator using high-power primary beams at the rare isotope science project (RISP) in Korea. The maximum beam power is planned to be 400 kW, and a third of the primary beam power deposits at the isotope production target and the rest are dissipated at the beam dump. The beam dump is designed to be a rotating water drum, which is ...

The carotenoid peridinin is abundant in the biosphere, as it is the main pigment bound by the light-harvesting complexes of dinoflagellates, where it collects blue and green sunlight and transfers energy to chlorophyll a with high efficiency. Its molecular structure is particularly complex, giving rise to an intricate excited state manifold, which includes a state with charge-transfer character...

We generated replacement sets for three highly conserved residues, Pro196, Pro197 and His199, that flank the catalytic nucleophile, Cys198. Pro196 and Pro197 have restricted mobility that could be important for the structural transitions known to be essential for activity. To test this hypothesis we obtained and characterized 13 amino acid substitutions for Pro196, 14 for Pro197 and 14 for His1...

Carving is a common technique in digital forensics to recover data from a memory dump of a device. In contrast to existing approaches, we investigate the carving problem for sets of memory dumps. Such a set can, for instance, be obtained by dumping the memory of a number of smart cards or by regularly dumping the memory of a single smart card during its lifetime. The problem that we define and ...

When a software failure occurs in the field, it is often difficult to reproduce. Guided by a memory dump at the moment of failure (a “core dump”), our RECORE test case generator searches for a series of events that precisely reconstruct the failure from primitive data. Applied on seven non-trivial Java bugs, RECORE reconstructs the exact failure in five cases without any runtime overhead in pro...

In 1985, the scrap tire industry was created when Minnesota became the first state to develop specific legislation and regulations for scrap tires. Up to that time, many scrap tires, like most solid and household wastes, went into the l1)unicipal dump. Those tires not placed in the dump went into stock piles, some of which still exist today. Prior to 1985, few, ifany scrap tires were processed....

Physical, chemical and bacteriological analyses were carried out of water samples from three boreholes located near a landfill, and or soil samples at Akure, Nigeria, to ascertain the effect of the dumpsite on the groundwater and soil quality. The samples from borehole locations with radial distances of 50, 80, and 100 m, respectively, away from the landfill and twelve soil samples collected at...

We investigate pump-dump photoassociation of ultracold molecules with amplitudeand phase-modulated femtosecond laser pulses. For this purpose a perturbative model for the light-matter interaction is developed and combined with a genetic algorithm for adaptive feedback control of the laser pulse shapes. The model is applied to the formation of Rb2 molecules in a magneto-optical trap. We find for...

Because of the complexity and diversity of the terrain and cover types in coal mine dump, it is difficult to set up the research points in the wild dump. This paper introduces an embedded GPS and GIS technology and develops portable environmental information acquisition system applied to coal mine dump investigation. The system mainly achieves the functions of soil, vegetation, microclimate sam...

This paper presents an alternative to traditional file carving, targeted to cell phone forensics. The proposed algorithm processes the cell phone memory dump thanks to a previous partial knowledge of the content of the regular files present in the memory dump. The memory dump is decomposed into elementary parts, each part classified according to the file type it is supposed to belong to, and fi...
