De minimis non curat lex: A Profound Juridical Unity?

De minimis curat lex: New Zealand law and the challenge of the very small

In 2010, the New Zealand Government commissioned a review on the ability of New Zealand's regulatory systems to manage the potential health, safety and environmental risks posed by manufactured nanomaterials. Whilst some of the gaps identified by this review are specific to New Zealand's regulatory arrangements, other potential gaps are common to regulators in different jurisdictions. Scientifi...

Why De Minimis?

De minimus non curat lex--virtual thresholds for cancer initiation by tobacco specific nitrosamines--prospects for harm reduction by smokeless tobacco.

Whereas the impact of tobacco specific nitrosamines in smokers is obscured by the presence of numerous other carcinogens and promoters, for smokeless tobacco virtually all the carcinogenic potential is associated with 4-(nitrosomethylamino)-1-(3-pyridyl)-1-butanone (NNK) and N'-nitrosonornicotine (NNN). In some countries exposure to smokeless tobacco with extremely high nitrosamine concentratio...

Generalized Fibonacci recurrences and the lex-least De Bruijn sequence

The skew of a binary string is the difference between the number of zeroes and the number of ones, while the length of the string is the sum of these two numbers. We consider certain suffixes of the lexicographicallyleast de Bruijn sequence at natural breakpoints of the binary string. We show that the skew and length of these suffixes are enumerated by sequences generalizing the Fibonacci and L...
