Genetic diversity of peanut (Arachis hypogaea L.) and its wild relatives based on the analysis of hypervariable regions of the genome [PDF]

open access: yes, 2004
BACKGROUND: The genus Arachis is native to a region that includes Central Brazil and neighboring countries. Little is known about the genetic variability of the Brazilian cultivated peanut (Arachis hypogaea, genome AABB) germplasm collection at the DNA ...

Entanglement under restricted operations: Analogy to mixed-state entanglement [PDF]

open access: yes, 2006
We show that the classification of bi-partite pure entangled states when local quantum operations are restricted yields a structure that is analogous in many respects to that of mixed-state entanglement.

Recover Fine-Grained Spatial Data from Coarse Aggregation

open access: yes, 2017
In this paper, we study a new type of spatial sparse recovery problem, that is to infer the fine-grained spatial distribution of certain density data in a region only based on the aggregate observations recorded for each of its subregions.

The many encounters of Thomas Kuhn and French epistemology [PDF]

open access: yes, 2017
The work of Thomas Kuhn has been very influential in Anglo-American philosophy of science and it is claimed that it has initiated the historical turn. Although this might be the case for English speaking countries, in France an historical approach has ...

New spin squeezing and other entanglement tests for two mode systems of identical bosons [PDF]

open access: yes, 2014
For any quantum state representing a physical system of identical particles, the density operator must satisfy the symmetrization principle (SP) and conform to super-selection rules (SSR) that prohibit coherences between differing total particle numbers.

Rayleigh and depinning instabilities of forced liquid ridges on heterogeneous substrates

open access: yes, 2011
Depinning of two-dimensional liquid ridges and three-dimensional drops on an inclined substrate is studied within the lubrication approximation. The structures are pinned to wetting heterogeneities arising from variations of the strength of the short ...

Characterizing electron entanglement in multiterminal mesoscopic conductors

open access: yes, 2007
We show that current correlations at the exit ports of a beam splitter can be used to detect electronic entanglement for a fairly general input state. This includes the situation where electron pairs can enter the beam splitter from the same port or be ...

The resource theory of quantum reference frames: manipulations and monotones

open access: yes, 2008
Every restriction on quantum operations defines a resource theory, determining how quantum states that cannot be prepared under the restriction may be manipulated and used to circumvent the restriction.
