A proper understanding of Millikan [PDF]

open access: yes, 2006
Ruth Millikan’s teleological theory of mental content is complex and often misunderstood. This paper motivates and clarifies some of the complexities of the theory, and shows that paying careful attention to its details yields answers to a number of ...

Renormalization of the isovector $\pi N$ amplitude in pionic atoms [PDF]

open access: yes, 2003
The extraction of the isovector s-wave pi N amplitude from pionic atoms is studied with special emphasis on uncertainties and their dependence on the assumptions made regarding the neutron density distributions in nuclei and on the size of the data base ...

The close circumstellar environment of the semi-regular S-type star Pi^1 Gruis [PDF]

open access: yes, 2008
We study the close circumstellar environment of the nearby S-type star Pi^1 Gruis using high spatial-resolution, mid-infrared observations from the ESO/VLTI.

Bohr almost periodic maps into $K(\pi ,1)$ spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1997
Let \(X\) be a locally finite simplicial complex of finite topological dimension, and assume further that \(X\) is a \(K(\pi,1)\)-space where \(\pi\) is a group whose only abelian subgroups are infinite cyclic. The first hypothesis ensures that there exists an imbedding of \(X\) in Euclidean space \(R^n\).

Permutations over cyclic groups [PDF]

open access: yes, 2012
Generalizing a result in the theory of finite fields we prove that, apart from a couple of exceptions that can be classified, for any elements $a_1,...,a_m$ of the cyclic group of order $m$, there is a permutation $\pi$ such that $1a_{\pi(1)}+...+ma_{\pi(

Real $K(\pi,1)$ arrangements from finite root systems [PDF]

open access: yesMathematical Research Letters, 1996
The author studies the complement of certain classes of subspace arrangements in real \(n\)-space that are invariant under the action of \(S_n\) by permuting the coordinates and whose subspaces are defined by equality of certain coordinates. Such arrangements are called ``orbit arrangements'' and were introduced by \textit{A.

Identification of rice blast resistance genes in the rice varieties developed with DNA-markers assistance

open access: yesЗерновое хозяйство России, 2018
Eight rice varieties of the Far East breeding have been studied by the method of DNA-typing to establish the presence of rice blast resistance genes. Six varieties possess one gene each: the varieties ‘Khankaysky 429’ and ‘Khankaysky 52’ possess the gene

Novel Soft-Pion Theorem for Long-Range Nuclear Parity Violation

open access: yes, 2018
The parity-odd effect in the Standard Model weak neutral current reveals itself in the long-range parity-violating nuclear potential generated by the pion exchanges in the $\Delta I=1$ channel with the parity-odd pion-nucleon coupling constant $h_\pi^1$.

The Deep Past of the White Shark, Carcharodon carcharias, in the Mediterranean Sea: A Synthesis of Its Palaeobiology and Palaeoecology

open access: yesLife, 2023
The white shark, Carcharodon carcharias, is the main top predator of the present-day Mediterranean Sea. The deep past of C. carcharias in the Mediterranean is witnessed by a rather conspicuous, mostly Pliocene fossil record.
