On Lucky Primes
Winkler (1988) and Pauer (1992) present algorithms for a Hensel lifting of a modular Gröbner basis over lucky primes to a rational one. They have to solve a linear system with modular polynomial entries that requires another (modular) Gröbner basis computation. After an extension of luckiness to arbitrary (commutative noetherian) base rings we show in this paper that for a homogeneous polynomia...
متن کاملLucky Factors
We propose a new method to select amongst a large group of candidate factors — many of which might arise as a result of data mining — that purport to explain the cross-section of expected returns. The method is robust to general distributional characteristics of both factor and asset returns. We allow for the possibility of time-series as well as cross-sectional dependence. The technique accomm...
متن کاملLucky: Reflecting on Relationships in Family Medicine.
Based on my 30 years as a neurologist, I knew his situation was not going to be a picnic, even before we met. An examination confirmed he had a cerebellar-like syndrome. I turned to Chris, paused, and then thought for a moment. “Your unsteady feeling, did it just happen or has it been going on for months?” His wife answered, “I think Chris has mentioned this to me for years.” When he nodded yes...
متن کاملA Lucky Wound
an absolute bull's-eye through the face and out at the back of the neck, and was inflicted by a rifle bullet. He was not rendered unconscious, and was seen only shortly after, by the regimental doctor, Lieutenant Baker, i.m.s. He was transferred the same day to the ambulance, where a detailed examination was made, which has led to the report. There was a small entrance wound just beneath the br...
متن کاملBioCode: Third time lucky?
Fifteen year ago a draft BioCode was presented to the taxonomic community (Greuter et al. 1996). There is now a new version, published in Taxon (Greuter et al. 2011) and available online on the International Committee on Biological Nomenclature website as well as that of the International Commision for Zoological Nomenclature. Has the BioCode matured since it was last put forward? Was it ahead ...
