Dimensionally stable one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) high aspect ratio crystalline metal oxide nanostructures are fabricated using soft nanoimprint lithography with inks comprised of nanoparticle (NP) dispersions in solvent or sol–gel precursors for the oxide. Crystalline TiO2 indium tin (ITO) NP imprinted a permeable patterned poly(dimethylsiloxane) (PDMS) stamp to yield robust that dimensionally calcination (less than 8% linear shrinkage feature...

Dynamic mechanical measurements were used to investigate the effect of small molecule additives on order-to-disorder transitions (ODTs) Pluronic, poly(ethylene oxide) (PEO)–poly(propylene (PPO)–PEO triblock copolymer surfactant melts. The contain multiple functional groups (carboxyl or hydroxyl), which selectively interact with PEO component Pluronic via hydrogen bonding, thereby effectively increasing χ system and leading microphase separation in otherwise disordered ODTs these...

Acute leukemia is one of the leading malignancies in United States with a mortality rate strongly influenced by phenotype. This phenotype based on detection cell associated antigens normally expressed during leucopoietic differentiation. In this regard, classified as lymphoid or myeloid also candidate for corresponding chemotherapy protocol. Additionally, subtype degree differentiation and maturity influence prognosis, response to treatment, median survival times. paper, we analyze...

Dimensionality reduction is the process of mapping high-dimension patterns to a lower dimension subspace. When done prior classification, estimates obtained in subspace are more reliable. For some classifiers, there also an improvement performance due removal diluting effect redundant information. A majority present approaches dimensionality based on scatter matrices or other statistics data which do not directly correlate classification accuracy. The optimality criteria choice for purposes...

Compact characterization of soil moisture at a given scale using self-organizing feature maps is presented.

Average latent heat flux computed original image 21204 pixels and are comparable.

Nanoimprint lithography (NIL) offers high precision patterning of structures as small 50 nm using wafer-based or roll-to-roll process platforms, however current resist systems offer little functionality. We developed hybrid UV-NIL resists containing up to 90 wt. % nanoparticles with excellent optical transparency for direct device including a readily scalable print, lift, and stack approach producing large-area, 3D photonic crystal (PC) gratings. have also extended the NIL directly print...

In this paper we present MUSIK, a MUltimedia Service Integration frameworK to address two important problems associated with smart environments: user mobility and multi-device content delivery. We define multimedia service integration as the concept of intelligently delivering services mobile-user equipped multiple networked computing devices. argue that middleware layer is best place problem design MUSIK proxy based framework. The framework relies on Session Initiation Protocol (SIP) basis...

Additional inputs to a feedforward network, derived from the output of hidden layer neurons, allow network deal with temporal pattern recognition and reproduction tasks. These 'network derived' or 'context' augment 'true' retain past information necessary for sequence processing. The choice which neurons provide context is difficult. Use all increases size overall resulting in poorer generalization performance. problem complicated due difficulty choosing number first place. In this paper, we...

Besides regular integer Shapiro steps observed when voltage is measured between input and output leads dc biasing current, we also found additional transverse for large value current. An explanation these given terms competing circulating currents bridge.
