55Census: do papers state what the cells were grown in and on, and whether the culture was moved?
# Do reprogramming papers say what the cells were grown in, on, and whether the dish was shaken? ## Answer For vessel and surface the answer is essentially yes; for agitation it is essentially no. Surface (feeder cells…

Gap in AI Audit Standardization
## Answer The main unresolved barrier is the absence of a shared, operationally precise audit regime: there is no agreed set of procedures, taxonomies, standards and auditor qualifications, so audit results cannot be tr…

Retroviral/lentiviral reprogramming efficiency in human peripheral blood mononuclear cells
## Answer Retroviral or lentiviral OSKM delivery into human PBMCs is very inefficient where it is reported at all. The two lentiviral papers print 0.001-0.0002% (Staerk 2010) [c00c1391-5384-4c18-a334-3a5fa37419a0] and 0…

Centiloid scale conversion method for amyloid PET tracers
## Answer There is no single arithmetic SUVR-to-Centiloid conversion: the Centiloid scale is a calibrated 0-100 scale, and each tracer or analysis pipeline needs its own paired calibration against the standard PiB metho…

Rarefaction vs extrapolation for temporal species richness comparison
## Answer Coverage-based rarefaction (Chao & Jost framework) is the better-supported choice for temporal richness comparisons when sampling effort varies across years, but the corpus does not show that it is more accura…

[replication] Has any subsequent study replicated the Okumura et al. 2019 CD34+-enrichment result (5.58% versus 0.17% for bulk PBMCs) in a second donor or with a different Sendai vector?
## Answer No study in the corpus replicates the Okumura et al. 2019 contrast of 5.58% for CD34+-enriched cells against 0.17% for bulk PBMCs, in a second donor or with a different Sendai vector. The contrast comes from o…

V4 vs V3-V4 region taxonomic resolution comparison

[coverage] Is there a primary paper reporting bare retroviral or lentiviral OSKM reprogramming efficiency in human dermal fibroblasts, scored by a stated immunostain (AP+, TRA-1-60+, or NANOG+), with an explicit donor count and a denominator matching cells at the point of transduction rather than cells replated later?
## Answer No verified paper meets all of the requested conditions at once: bare retroviral or lentiviral OSKM, human dermal fibroblasts, a named immunostain among AP, TRA-1-60 and NANOG, an explicit donor count, and a d…

[measurement] Does any study report AP+ and TRA-1-60+ colony counts on the same reprogramming material without first pre-selecting colonies by hESC-like morphology, so AP's known tendency to mark partially reprogrammed colonies can actually be measured against TRA-1-60?
## Answer The supplied verified evidence **does not yet provide a qualifying matched measurement of AP+ and TRA-1-60+ colony counts on the same unselected reprogramming material**. A later BRD2 study is a promising cand…
