  Identification of an abnormal beryllium lymphocyte proliferation test

Thanks to Drs Stange and Furman, ORISE-Rocky Flats for identifying these errors 

1) Throughout the paper all "logs" are base e,  i.e. Ln(x) and log(x) 
 mean the same thing
              /x
              |   1
  log(x)  =   |  -- dt  for x in <0, +infinity>  = Ln(x) ,
             / 1  t

the "natural logarithm"  as usually defined in mathematics.  Unfortunately,
none of the authors, reviewers, or editors noticed this inconsistency. 

In the pre-computer days ( say < 1960) when tables were used to find
"logs", base 10 was used as a matter of computation convenience.

The most flagrant inconsistency occurs in Step 5 of Sec 2.2, i.e.

 SLsi = Ln(SI)/SE[log(SI)] should be   SLsi = Ln(SI)/SE[Ln(SI)]

In some figures  LN(M,S) is used to represent the log normal
distribution with location parameter M and scale parameter S. 

2) On page 50 Change:
"... in Serum 3040083 is 48/56 or 85.7% 1- and the specificity (false
positive rate) is 992/1024 or 96.9%"

To:
"... in Serum 3040083 is 48/56 or 85.7% and the specificity (1 - false
positive rate) is 992/1024 or 96.9%"

3) Exhibit A4 Pages 54-55 should appear as
