Quadratic Difference Operators and Structural Compression in the Erdős–Rankin Prime Gap Problem
Using the 52 known even perfect numbers, this paper identifies underlying structural regularities by projecting discrete arithmetic patterns into a continuous geometric space via a characteristic quadratic mapping.

Development of retroviral vectors for selective gene transfer into haematopoietic precursor cells and investigation of the gamma-retroviral R-peptide mediated membrane fusion [PDF]
, 2009 Eine in vivo Modifizierung von Blutstammzellen wäre für eine Reihe gentherapeutischer Therapieansätze vorteilhaft. Dies würde voraussetzen, dass retrovirale Vektoren gezielt auf Blutstammzellen ausgerichtet werden können.

Contributions to Analytic Number Theory
, 2004 This paper reports on some recent contributions to the theory of multiplicative arithmetic semigroups, which have been initiated by John Knopfmacher's work on analytic number theory. They concern weighted inversion theorems of the Wiener type, mean-

Factorizations of a^n±1, 13 ≤ a < 100
, 1992 As an extension of the "Cunningham" tables, we present tables of factorizations of a n \Sigma 1 for 13 a ! 100. The exponents n satisfy a n ! 10 255 if a ! 30, and n 100 if a 30.

Factorizations of a^n ± 1, 13 ≤ a < 100: Update 2
, 1996 This Report updates the tables of factorizations of a n \Sigma 1 for 13 a ! 100, previously published as CWI Report NM-R9212 (June 1992) and updated in CWI Report NM-R9419 (September 1994). A total of 760 new entries in the tables are given here.

Update 1 to: Factorizations of a
, 1994 In an earlier Report (NM-R9212, June 1992), two of us gave tables of factorizations of a n \Sigma 1 for 13 a ! 100. The exponents n satisfied a n ! 10 255 if a ! 30, and n 100 if a 30.
