Solid State Molecular Reactors in Space [PDF]

open access: yesEAS Publications Series, 2011
Lunar minerals and impact glasses, convert the polyatomic beam of solar wind (SW) ions into a flux of small molecules (e.g., H-2, N-2, H2O, CO, CO2, CH4, C2H4, C2H6, HCN, metal carbides and deuterides, etc.). They thus behave as "Solid State Molecular Reactors".

Degenerate double solids as twister spaces [PDF]

open access: yesCommunications in Analysis and Geometry, 2002
A metric on a four-manifold is called self-dual if the anti-self-dual part of the Weyl tensor vanishes. In this case the corresponding twistor space is a complex manifold. A closed four-manifold with a self-dual metric of positive scalar curvature is homeomorphic to a sphere or to a connected sum of \(n\) copies of \({\mathbb C} P ^ n\). By results of \

Layering and wetting transitions for an SOS interface [PDF]

open access: yes, 2010
We study the solid-on-solid interface model above a horizontal wall in three dimensional space, with an attractive interaction when the interface is in contact with the wall, at low temperatures. There is no bulk external field.

RELATIVE SOLIDITY FOR SPACES OF HOLOMORPHIC FUNCTIONS [PDF]

open access: yesMathematical Proceedings of the Royal Irish Academy, 2004
The author studies sequence spaces associated with holomorphic functions on the unit disc, identifying any such function with his Taylor sequence. The author's abstract: We define and investigate relative solidity for sequence spaces, and use it to study spaces of holomorphic functions on the unit disk and related coefficient multiplier spaces.

On order-bounded subsets of locally solid Riesz spaces

open access: yes, 2015
In a topological Riesz space there are two types of bounded subsets: order bounded subsets and topologically bounded subsets. It is natural to ask (1) whether an order bounded subset is topologically bounded and (2) whether a topologically bounded subset

Influence of Cu/Li ratio on the microstructure evolution of bobbin-tool friction stir welded Al–Cu–Li alloys

open access: yesJournal of Materials Research and Technology, 2019
Two modern aluminum lithium alloys were welded by semi-stationary bobbin tool friction stir welding. The influence of the Cu/Li ratio on precipitation phenomena under process heat impact was investigated by comparing the response of low Cu/Li alloy 2196 ...

Solidity in Sequence Spaces

open access: yesRevista Matemática Complutense, 1991
Bekanntlich heißt ein Raum \(E\) von komplexwertigen Folgen \(x=(x_ n)\) solid, wenn gilt: \(x\in E\;\&\;| y_ n|\leq| x_ n|\), \((n\in\mathbb{N})\Rightarrow y\in E\). Diese Eigenschaft läßt sich auf vektorwertige Folgenräume in verschiedene Richtungen verallgemeinern. Für einen normierten Raum \(X\) bezeichne \(s(X)\) den Raum aller Folgen \(x=(x_ n)\)

Anderson localization and Mott insulator phase in the time domain [PDF]

open access: yes, 2015
Particles in space periodic potentials constitute standard models for investigation of crystalline phenomena in solid state physics. Time periodicity of periodically driven systems is a close analogue of space periodicity of solid state crystals.
