Strain Engineering of Ge Quantum Wells in Planar Ge/Si1 − xGex Heterostructures
Advanced Materials Interfaces, EarlyView.Germanium is explored as a promising semiconductor for quantum applications due to long hole spin coherence, superconducting correlations, and CMOS compatibility. This work investigates in‐plane and out‐of‐plane strain in Ge quantum wells embedded in Si1 − xGex barriers to engineer the electronic properties of the wells.

Nonequilibrium Period with Emergence of Marangoni Circulations in Meniscus Splitting
Advanced Materials Interfaces, EarlyView.The emergence and evolution of Marangoni convection in the meniscus splitting phenomenon are investigated. During the mass circulation of viscous fluids, the confluence and bifurcation of polymer dispersions beneath the evaporative interface lead to the inhomogeneous densification of the skin layer.

The equivariant Lefschetz fixed point theorem for proper cocompact G-manifolds
, 2001 Suppose one is given a discrete group G, a cocompact proper G-manifold M, and a G-self-map f of M. Then we introduce the equivariant Lefschetz class of f, which is globally defined in terms of cellular chain complexes, and the local equivariant Lefschetz

A Schauder fixed point theorem in semilinear spaces and applications
, 2013 In this paper we present existence and uniqueness results for a class of fuzzy fractional integral equations. To prove the existence result, we give a variant of the Schauder fixed point theorem in semilinear Banach spaces.MSC:34A07, 34A08.

A Generalization of Kannan's Fixed Point Theorem
Fixed Point Theory and Applications, 2009 In order to observe the condition of Kannan mappings, we prove a generalization of Kannan's fixed point theorem. Our theorem involves constants and we obtain the best constants to ensure a fixed point.

Lefschetz fixed point theorem for digital images
, 2013 In this article we study the fixed point properties of digital images. Moreover, we prove the Lefschetz fixed point theorem for a digital image. We then give some examples about the fixed point property.
