The speed of integrated circuits is ultimately limited by the mobility of electrons or holes, which depend on the effective mass in a semiconductor. Here, building on an analogy with electromagnetic metamaterials and transformation optics, we describe a transport regime in a semiconductor superlattice characterized by extreme anisotropy of the effective mass and a low intrinsic resistance to mo...

extended abstract 1. introduction the story of a hero’s journey and weathering arduous stages for the purpose of accomplishing a specific objective and subsequently bestowing the gifts of that tortuous journey on companions is an archetype which instigated joseph campbell (1904-1987), an american mythologist, to propound a comprehensive outline to portray an archetype of a heroes’ journey, with...

Nanophotonic devices offer an unprecedented ability to concentrate light into small volumes which can greatly increase nonlinear effects. However, traditional plasmonic materials suffer from low damage thresholds and are not compatible with standard semiconductor technology. Here we study the nonlinear optical properties in the novel refractory plasmonic material titanium nitride using the Z-sc...

weeding, and reduced rates or fewer applications of herbicides may be required for weed control. Some accessions of rice (Oryza sativa L.) have been shown to A useful tool for breeders would be an assay to screen inhibit the growth of barnyardgrass (Echinochloa crus-galli (L.) Beauv.). Our objective was to determine if high-performance liquid accessions and individual plants within accessions f...

We present a technique in which small solute nonlinearities may be extracted from large solvent signals by performing simultaneous Z-scans on two samples (solvent and solution). By using a dual-arm Z-scan apparatus with identical arms, fitting error in determining the solute nonlinearity is reduced because the irradiance fluctuations are correlated for both the solvent and solution measurements...

Using connectionist modelling, Thomas and Karmiloff-Smith claim that developmental disorders in children are characterised by atypical trajectories and an ultimate functional architecture that is fundamentally different from normal. We argue that there is no empirical evidence for these claims in any developmental disorder and that the available evidence provides support for residual normality ...

In this work we consider a method for parallelizing matrix factorization algorithms on systems with Intel © Xeon Phi TM coprocessors. We provide performance results of matrix factorization routines implementing this approach and available in Intel © Math Kernel Library (Intel MKL) on the Intel © Xeon © processor line with Intel Xeon Phi coprocessors. Summary New heterogeneous systems consisting...

Nonlinear optical imaging is a powerful method for observing bulk and interfacial phenomena in time and space. Here, we present a stepby-step description of how to carry out second harmonic generation imaging with a kHz amplifier laser system and demonstrate its applicability for SHG microscopy studies of highly size-resolved colloidal CdSe quantum dots having radii of 1-2 nm deposited on glass...

This paper summarizes the history of introducing the Mead-&-Conway VLSI design revolution in Europe. Although the academic scene in Europe was watching the DARPA-supported break-through in the U.S., all national governments declined support by pointing toward the missing funding in all neighbor countries – a classical deadlock. This paper reports how later the E.I.S. project completely removed ...

In the last three years or so we at Enterprise Platforms Group at Intel Corporation have been applying formal methods to various problems that arose during the process of defining platform architectures for Intel’s processor families. In this paper we give an overview of some of the problems we have worked on, the results we have obtained, and the lessons we have learned. The last topic is addr...
