Magnetic and electric properties of bismuth ferrite lead titanate ceramics [PDF]

open access: yes, 2010
Solid solutions of multiferroic BiFeO3 doped with ferroelectric PbTiO3 (BFPT) can be prepared by conventional mixed oxide processing to produce a range of polycrystalline ceramics ranging throughout the xBiFeO3 - (1-x)PbTiO3 series. Sintered ceramics are

Coincidence and modality [PDF]

open access: yes, 2012
How should we understand de re modal features of objects, if there are such features? Any answer to the question is connected to how we should think about coincident objects, objects which occupy the same spatio-temporal region and share the same ...

Early atomic models - from mechanical to quantum (1904-1913) [PDF]

open access: yes, 2012
A complete history of early atomic models would fill volumes, but a reasonably coherent tale of the path from mechanical atoms to the quantum can be told by focusing on the relevant work of three great contributors to atomic physics, in the critically ...

Neutron stars: Cosmic laboratories for matter under extreme conditions [PDF]

open access: yes, 2016
The true nature and the internal constitution of the compact stars known as neutron stars (NSs) is one of the most fascinating enigma in modern astrophysics.

Is There a Compelling Argument for Ontic Structural Realism? [PDF]

open access: yes, 2011
Structural realism first emerged as an epistemological thesis aimed to avoid the so-called pessimistic meta-induction on the history of science. Some authors, however, suggested that the preservation of structure across theory-change is best explained by

Applications of artificial neural networks (ANNs) in several different materials research fields [PDF]

open access: yes, 2010
PhDIn materials science, the traditional methodological framework is the identification of the composition-processing-structure-property causal pathways that link hierarchical structure to properties.

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

Andisols [PDF]

open access: yes, 2012
Andisols are soils that typically form in loose volcanic ejecta (tephra) such as volcanic ash, cinders, or pumice. They are characterized by andic properties that include physical, chemical, and mineralogical properties that are fundamentally different ...

Atom cavity encoding for NP-complete problems

open access: yesQuantum Frontiers
We consider an atom-cavity system having long-range atomic interactions mediated by cavity modes. It has been shown that quantum simulations of spin models with this system can naturally be used to solve number partition problems.

Configuration transitions of divacancies in silicon and germanium [PDF]

open access: yesЯдерна фізика та енергетика, 2013
High-resistance samples p-Si (p0 = (1.63 - 7.09)·1011 cm-3) and n-Si (n0 = 1.19·1014 cm-3), grown by the float-ing zone melting after irradiation with fast neutron reactor at 320 C after isothermal and isochronal annealing were studied.
