Clastic facies models, a personal perspective

Mouse models for melanoma: a personal perspective.

Complex biological processes often require in vivo analysis, and many important research advances have been made using mice as a model for the study of various biological systems. Cutaneous melanomas are tumors originating from skin melanocytes, which are present in hair follicles, and interfollicular epidermal and dermal layers. Until recently, mouse melanoma models were largely based on trans...

The Evolution of Linear Models in SAS: A Personal Perspective

Phenomenal growth in computational power from 1970 through 2010 enabled a parallel expansion in linear model methodology. From humble beginnings in agriculture, linear model applications are now essential in sciences of genetics, education, and biostatistics, to name a few. Indeed, the meaning of "linear models" has evolved accordingly. Developers at SAS Institute have been in the forefront of ...

Incompleteness: A Personal Perspective

After proving the completeness of the system of predicate logic in his doctoral dissertation (1929), Gödel has continued the investigation of the completeness problem for more comprehensive formal systems, especially for systems encompassing all known methods of mathematical proof. In 1931 (see [28, 25]) Gödel proved his famous (first) incompleteness theorem, which in modern terms reads: Every ...

A Personal Perspective

It is generally accepted good animal welfare and good science are inseparable; that one of the hallmarks of good science is that scientifically valid, reproducible experiments seek to identify and eliminate unwanted variables; and that the primary effects directly attributable to the controlled experimental variables can be confused with secondary and tertiary changes if other variables or anim...
