Primitive free cubics with specified norm and trace [PDF]

open access: yes, 2010
The existence of a primitive free (normal) cubic x(3) ax(2) + cx b over a finite field F with arbitrary specified values of a (not equal 0) and b (primitive) is guaranteed.

KNOTS WITH DISTINCT PRIMITIVE/PRIMITIVE AND PRIMITIVE/SEIFERT REPRESENTATIVES [PDF]

open access: yesJournal of Knot Theory and Its Ramifications, 2012
Berge introduced knots that are primitive/primitive with respect to the genus 2 Heegaard surface, F, in S3; surgery on such knots at the surface slope yields a lens space. Later Dean described a similar class of knots that are primitive/Seifert with respect to F; surgery on these knots at the surface slope yields a Seifert fibered space.

Compositional Generalization for Primitive Substitutions [PDF]

open access: yesConference on Empirical Methods in Natural Language Processing, 2019
Compositional generalization is a basic mechanism in human language learning, but current neural networks lack such ability. In this paper, we conduct fundamental research for encoding compositionality in neural networks.

Contribution of the local RAS to hematopoietic function: a novel therapeutic target

open access: yesFrontiers in Endocrinology, 2013
The renin angiotensin system (RAS) has long been a known endocrine system that is involved in regulation of blood pressure and fluid balance. Over the last 2 decades, evidence has accrued that shows that there are local RAS that can affect cellular ...

Primitive Zonotopes

open access: yesDiscrete & Computational Geometry, 2017
We introduce and study a family of polytopes which can be seen as a generalization of the permutahedron of type $B_d$. We highlight connections with the largest possible diameter of the convex hull of a set of points in dimension $d$ whose coordinates are integers between $0$ and $k$, and with the computational complexity of multicriteria matroid ...

Fate Mapping Analysis Reveals That Adult Microglia Derive from Primitive Macrophages

open access: yesScience, 2010
Primitive Origins for Microglia Microglia are the resident macrophages of the central nervous system and are associated with neurodegeneration and brain inflammatory diseases.

3D Building Roof Modeling by Optimizing Primitive’s Parameters Using Constraints from LiDAR Data and Aerial Imagery

open access: yesRemote Sensing, 2014
In this paper, a primitive-based 3D building roof modeling method, by integrating LiDAR data and aerial imagery, is proposed. The novelty of the proposed modeling method is to represent building roofs by geometric primitives and to construct a cost ...

Primitive polynomials with prescribed second coefficient [PDF]

open access: yes, 2006
The Hansen-Mullen Primitivity Conjecture (HMPC) (1992) asserts that, with some (mostly obvious) exceptions, there exists a primitive polynomial of degree n over any finite fieldwith any coefficient arbitrarily prescribed.

A simultaneous solution to two problems on derivatives

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1986
Let A be a nonvoid countable subset of the unit interval [0,1] and let B be an Fσ-subset of [0,1] disjoint from A. Then there exists a derivative f on [0,1] such that 0≤f≤1, f=0 on A, f>0 on B, and such that the extended real valued function 1/f is also ...
