Bibliographic record
Abstract
International Symposium on SM/MPAC&SEED (Service Module/Micro Particles Capturer and Space Environment Exposure Device) Experiment" was held on March 10-11, 2008 at International Congress Center (Epochal Tsukuba), in Tsuba, Ibaraki, JAPAN.In the Symposium, 22 papers are presented, including three key-note presentations.The SM/MPAC&SEED, consisted of three identical sample units, was launched to ISS (International Space Station) by Progress on August 2001, and attached on the exterior surface of the Russian Service Module(SM) on October 2001.Each sample unit contained various materials to capture micro-particles and to examine the effects of space environment effects.The first unit was retrieved into inside the ISS by EVA (Extra-Vehicular Activity) on August 2002, and returned to the Earth on November 2002.The second unit was retrieved on February 2004, and returned to the Earth on April 2004.The final unit was retrieved on August 2005, and returned to the Earth on October 2005.All the units were successfully retrieved, and the analyses of the samples have been conducted.The unique feature of this experiment is that the identical samples were retrieved changing the space exposure duration.Symposia on SM/MPAC&SEED experiment have been held on March 2004, and on February 2006 for first and second retrieved samples, respectively.In the present, final Symposium, summarizing results of the SM/MPAC&SEED experiment for all the retrieved samples were reported.Analysis results are sometimes confusing and/or contradicted each other in some cases.One cause of this is that the material degradation process is complex phenomena, in which numerous factors are involved, such as atomic oxygen, ultraviolet rays, radiation, contaminants and so on.To understand the space environment effects exactly based on the limited data, exchange of information and experiences, and discussions among the related researchers are mandatory.In this Symposium, the discussions among the participants were active, and in-depth.I believe the Symposium contributed for the advances in this disciplines.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
