Introduction: The satellites of Saturn less than 150 km radius occupy several dynamical niches: within rings (Pan, Daphnis, Atlas, Prometheus, Pandora), Coorbiting (Janus and Epimetheus), orbiting among faint rings or in ring arcs (Aegaeon, Methone, Anthe, Pallene) [1], and populating libration regions of larger moons (Telesto, Calypso, Polydeuces, and Helene). Hyperion orbits between Titan and...
Background and Aim: the study of antibacterial properties of resin cements and modified glass ionomers is of great importance. The aim of this study was to determine the antibacterial effect of resin-modified glass ionomers and resin cements on cariogenic bacteria, Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus. Materials and Methods:In this experimental laboratory s...
The beta-chain repertoire of the T cells that infiltrate spontaneously regressing nevi (the halo nevus phenomenon) was studied. In addition to the infiltration of the halo nevi by cutaneous lymphocyte-associated Ag-positive lymphocytes, oligoclonal expansion of T cells was observed in all halo nevi of all patients. T cells using the same TCR beta-chain were observed in distinct halo nevi of the...
The popularity of ASR (automatic speech recognition) systems, like Google Voice, Cortana, brings in security concerns, as demonstrated by recent attacks. The impacts of such threats, however, are less clear, since they are either less stealthy (producing noise-like voice commands) or requiring the physical presence of an attack device (using ultrasound). In this paper, we demonstrate that not o...
The application of nuclear reactors for space power and/or propulsion presents some unique challenges regarding the operations and control of the power system. Terrestrial nuclear reactors employ varying degrees of human control and decision-making for operations and benefit from periodic human interaction for maintenance. In contrast, the control system of a space nuclear power plant (SNPP) em...
ABSTRACT We investigate the performance of group finding algorithms that reconstruct galaxy groups from positional information tracer galaxies are observed in redshift surveys carried out with multiplexed spectrographs. use mock light-cones produced by L-Galaxies semi-analytic model evolution which underlying reality is known. particularly focus on at high redshift, and how this affected choice...
