The importance of chemical communication in reproduction has been demonstrated many marine broadcast spawners. However, little is known about the use by echinoderms, nature compounds involved and their mechanism(s) action. Here, hypothesis that sea cucumber Holothuria arguinensis uses for aggregation spawning was tested. Water conditioned males, but not females, attracted both males females; gonad homogenates coelomic fluid had no effect on attraction. Male water, female stimulated females...

The goal of the HTTP REST API for Tape project is to provide a simple, minimalistic and uniform interface manage data transfers between Storage Endpoints (SEs) where source file on tape. collaboration developers WLCG storage systems (EOS+CTA, dCache, StoRM) transfer clients (gfal2, FTS). For some years, has been growing in popularity as preferred protocol many SEs. However — unlike other protocols such XRootD SRM does not include method stage files from tape disk prior transfer, forcing use...

The CERN Tape Archive (CTA) is the successor to CASTOR and tape backend EOS. It was designed meet needs of archival storage data from LHC Run–3 other experimental programmes at CERN. In wider Worldwide Computing Grid (WLCG), software landscape quite heterogeneous, but we are entering a period consolidation. A number sites have reevaluated their options choosing CTA for future needs. However, CTA’s original mandate imposed several design constraints which not necessarily optimal external...

The EOS disk + CERN Tape Archive (EOSCTA) service is CERN’s primary physics data long-term storage and archival solution for LHC Run 3. It entered production at during summer 2020 has since been serving all the non-LHC workflows involving to-and retrieval from tape. CTA system a complete redesign of previous tape software, cache workflows, which will need to scale rate requirements present activity period, as well one after. At time writing it already set new records monthly volume reached...
