Nesting of relations is very much essential for many database representations in reality. Nesting of relations tends to reduce the data redundancy in the relations. It helps in dropping certain constraints in normalization which tend to omit certain sensitive data when tried to be normalized. Query processing or conversion of data repositories, as required, can be easily being tackled by the ai...

Large strain-energy arising from lattice mismatch allows one-dimensional heteroepitaxial growth of InxGa1−xAs on silicon substrates without any catalyst or pattern assistance. In this paper, we show that in contrast to nanowires (NWs) grown by metal-catalyzed vapor−liquid− solid mechanism, strain-induced InxGa1−xAs NWs have several unique morphological features including no tapering, slight ben...

Nanowire field effect transistors (NW-FETs) can serve as ultrasensitive detectors for label-free reagents. The NW-FET sensing mechanism assumes a controlled modification in the local channel electric field created by the binding of charged molecules to the nanowire surface. Careful control of the solution Debye length is critical for unambiguous selective detection of macromolecules. Here we sh...

Branched nanostructures represent unique, 3D building blocks for the "bottom-up" paradigm of nanoscale science and technology. Here, we report a rational, multistep approach toward the general synthesis of 3D branched nanowire (NW) heterostructures. Single-crystalline semiconductor, including groups IV, III-V, and II-VI, and metal branches have been selectively grown on core or core/shell NW ba...

There has been tremendous interest and progress with synthesis of inorganic nanowires (NWs). However, much of the progress only resulted in NWs with diameters much greater than their respective quantum confinement scales, i.e. 10–100 nm. Even at this scale, NW-based materials offer enhanced charge transport and smaller diffusion length scales for improved performance with various electrochemica...

There has been a surge of paleo-climatic/environmental studies of Northwestern China (NW China), a region characterized by a diverse assortment of hydro-climatic systems. Their common approach, however, focuses on "deducing regional resemblance" rather than "exploring regional variance." To date, efforts to produce a quantitative assessment of long-term intra-regional precipitation variability ...

Decoders are employed to address individual NWs in crossbars (xbars) used for storage and computation. We report on the simulation and analysis of a membranebased nanowire (NW) decoder proposed by Pribat and Savage [1] that implements the randomized-contact decoder (RCD) introduced by Williams and Kuekes [2] and analyzed by Hogg et al [3] and Rachlin and Savage [4]. An RCD has two sets of paral...

Ag nanowire (NW) films obtained by the spraying the Ag NWs on the substrates were nano-welded by rapid thermal annealing (RTA) process and the effect of RTA process on the change of sheet resistance and optical transmittance of the Ag NW films was investigated. The increased number of Ag NW sprays on the substrate decreased the sheet resistance but also decreased the optical transmittance. By t...

The dietary patterns of sixty-four adolescents (thirty-seven young men and twenty-seven young women) between 15 and 17 years of age were examined by analysis of food, energy and nutrient intakes, over a period of 5 d, including a Sunday. Adolescents were identified for inclusion in two study groups: (1) overweight and obese subjects (O) with a BMI (kg/m2) > or = 75th percentile, and (2) subject...
