Self-assembled quantum dots (DQ) can be grown as stacks where the QD distance can be controlled with atomic layer control. This distance determines the interaction of the artificial atom states to form artificial molecules. The design of QD stacks becomes complicated since the structures are subject to inhomogeneous, long-range strain and growth imperfections such as non-identical dots and inte...

By combining density functional theory, nonequilibrium Green's function formulism and effective-Hamiltonian approaches, we demonstrate strain-engineered surface transport in Si(001), with the complete isolation of the Si surface states from the bulk bands. Our results show that sufficient tensile strain can effectively remove the overlap between the surface valence state and the bulk valence ba...

PURPOSE A high prevalence of tooth surface loss due to erosion is well recognized in the United Kingdom (UK), but not in the United States (US). This could be due to prevalence or perception or a combination of both. The aim of this study was to measure the prevalence of erosion of the upper permanent incisors in US and UK samples of 11-13 year old children. METHODS Convenience samples of 129...

Strains in Bradyrhizobium japonicum serocluster 123 are the major indigenous competitors for nodulation in a large portion of the soybean production area of the United States. Serocluster 123 is defined by the serotype strains USDA 123, USDA 127, and USDA 129. The objective of the work reported here was to evaluate the ability of two soybean genotypes, PI 377578 and PI 417566, to restrict the n...

Erratum As reported in the original paper [1], the Center for Regulatory Research on Tobacco Communication conducted a telephone survey in 2014–2015 with a national sample of adults ages 18 and older living in the United States (N = 5014). Poverty level was determined using the household size and income reported by the respondents and applying the federal poverty numbers available from the U.S....

patient care when prescribers must use an alternative agent,” whereas the FDA focuses only on “products used to prevent or treat a serious or life-threatening disease or medical condition for which there is no other available source with sufficient supply of that product or alternative drug available.”2–5 The Drug Information Service at University of Utah Health Care (UUHC), which partners with...

The accuracy of strategies combining heterogeneous mechanical tests and full-field strain measurement techniques is dependent on many factors. Recently, with different specimen shapes have been proposed using optimization or empirical knowledge. However, a comparison difficult task because studies use materials representations the stress states. This work discusses metrics, calculated from tens...

We have studied the influence of oxidation-induced strain on the electronic structure in Si quantum wires and quantum point contacts. The strain calculations were done using a semiempirical approximation which enabled three-dimensional (3-D) strain simulations of the device structures. The strain-induced deformation of the conduction band gives rise to a 3-D potential minimum having a depth of ...
