Fiber Optical Cable and Connector System (FOCCoS) for PFS/Subaru
FOCCoS, Fiber Optical Cable and Connector System, has the main function of
capturing the direct light from the focal plane of Subaru Telescope using
optical fibers, each one with a microlens in its tip, and conducting this light
through a route containing connectors to a set of four spectrographs. The
optical fiber cable is divided in 3 different segments called Cable A, Cable B
and Cable C. Multi-fibers connectors assure precise connection among all
optical fibers of the segments, providing flexibility for instrument changes.
To assure strong and accurate connection, these sets are arranged inside two
types of assemblies: the Tower Connector, for connection between Cable C and
Cable B; and the Gang Connector, for connection between Cable B and Cable A.
Throughput tests were made to evaluate the efficiency of the connections. A
lifetime test connection is in progress. Cable C is installed inside the PFI,
Prime Focus Instrument, where each fiber tip with a microlens is bonded to the
end of the shaft of a 2-stage piezo-electric rotatory motor positioner; this
assembly allows each fiber to be placed anywhere within its patrol region,
which is 9.5mm diameter.. Each positioner uses a fiber arm to support the
ferrule, the microlens, and the optical fiber. 2400 of these assemblies are
arranged on a motor bench plate in a hexagonal-closed-packed disposition.Comment: 11 pages, 20 figure

Terrestrial behavior in titi monkeys (Callicebus, Cheracebus, and Plecturocebus) : potential correlates, patterns, and differences between genera
For arboreal primates, ground use may increase dispersal opportunities, tolerance to habitat change, access to ground-based resources, and resilience to human disturbances, and so has conservation implications. We collated published and unpublished data from 86 studies across 65 localities to assess titi monkey (Callicebinae) terrestriality. We examined whether the frequency of terrestrial activity correlated with study duration (a proxy for sampling effort), rainfall level (a proxy for food availability seasonality), and forest height (a proxy for vertical niche dimension). Terrestrial activity was recorded frequently for Callicebus and Plecturocebus spp., but rarely for Cheracebus spp. Terrestrial resting, anti-predator behavior, geophagy, and playing frequencies in Callicebus and Plecturocebus spp., but feeding and moving differed. Callicebus spp. often ate or searched for new leaves terrestrially. Plecturocebus spp. descended primarily to ingest terrestrial invertebrates and soil. Study duration correlated positively and rainfall level negatively with terrestrial activity. Though differences in sampling effort and methods limited comparisons and interpretation, overall, titi monkeys commonly engaged in a variety of terrestrial activities. Terrestrial behavior in Callicebus and Plecturocebus capacities may bolster resistance to habitat fragmentation. However, it is uncertain if the low frequency of terrestriality recorded for Cheracebus spp. is a genus-specific trait associated with a more basal phylogenetic position, or because studies of this genus occurred in pristine habitats. Observations of terrestrial behavior increased with increasing sampling effort and decreasing food availability. Overall, we found a high frequency of terrestrial behavior in titi monkeys, unlike that observed in other pitheciids
