The Right Order of Concepts: Graßmann, Peano, Gödel and the Inheritance of Leibniz's Universal Characteristic

open access: yesPhilosophia Scientiæ, 2014
This paper tackles the question of whether the order of concepts was still a relevant aspect of scientific rigour in the 19th and 20th centuries, especially in the case of authors who were deeply influenced by the Leibnizian project of a universal ...

Research on Universal Combinatorial Coding

open access: yesThe Scientific World Journal, 2014
The conception of universal combinatorial coding is proposed. Relations exist more or less in many coding methods. It means that a kind of universal coding method is objectively existent. It can be a bridge connecting many coding methods.

FRACTAL STRUCTURE OF TITANIUM NITRITE DEPOSITED ON STAINLESS STEEL SUBSTRATE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2014
On the basis of images obtained using scanning tunneling microscope, it was shown that the fractal dimension can be considered as some universal surface characteristic of the titanium nitrite, deposited on stainless steel.

Universal Ratios of Characteristic Lengths in Semidilute Polymer Solutions

open access: yes, 2002
We use experimental and simulation data from the literature to infer five characteristic lengths, denoted $\xi_s$, $\xi_f$, $\xi_\Pi$, $\xi_\phi$, and $\xi_D$ of a semidilute polymer solution.

Classification of linearly compact simple Nambu-Poisson algebras [PDF]

open access: yes, 2015
We introduce the notion of universal odd generalized Poisson superalgebra associated to an associative algebra A, by generalizing a construction made in [5].

Universal characteristic factors and Furstenberg averages [PDF]

open access: yesJournal of the American Mathematical Society, 2006
Let X = ( X 0 , B , μ , T ) X=(X^0,\mathcal {B},\mu ,T) be an ergodic probability measure-preserving system. For a natural number k k we consider the averages (*)

On the abelian fivefolds attached to cubic surfaces

open access: yes, 2013
To a family of smooth projective cubic surfaces one can canonically associate a family of abelian fivefolds. In characteristic zero, we calculate the Hodge groups of the abelian varieties which arise in this way.

Basepoint freeness for nef and big line bundles in positive characteristic

open access: yes, 1998
A necessary and sufficient condition is given for semi-ampleness of a numerically effective (nef) and big line bundle in positive characteristic. One application is to the geometry of the universal stable curve over M_g, specifically, the semi-ampleness ...

A conserved function for pericentromeric satellite DNA

open access: yeseLife, 2018
A universal and unquestioned characteristic of eukaryotic cells is that the genome is divided into multiple chromosomes and encapsulated in a single nucleus. However, the underlying mechanism to ensure such a configuration is unknown.

A note on the restricted universal enveloping algebra of a restricted Lie-Rinehart Algebra

open access: yes, 2015
Lie-Rinehart algebras, also known as Lie algebroids, give rise to Hopf algebroids by a universal enveloping algebra construction, much as the universal enveloping algebra of an ordinary Lie algebra gives a Hopf algebra, of infinite dimension.
