Conductive polymer composites (CPCs) of carbon nanotubes (CNTs) and graphite nanosheet (GNP)-filled thermoplastic polyurethane (TPU) are 3D-printed into flexible piezoresistive sensors via fused filament fabrication. The sensor, with a customized lever-cross structure, allows detection stretching out-of-plane forces different magnitudes frequencies. force direction is obtained by combing the re...

Self-organizing maps are widely used in visual data mining. This paper proposes a new visualization approach for GHSOM algorithm, a hierarchical variant of SOM. The method is based on pie charts. That improves the visualization in hierarchical data structures making possible to extract all the existing relationships among the attributes of the neurons at any hierarchy level. The methodology is ...

This paper explains the co-ordinate based location system built for XenoSearch, a resource discovery system in the XenoServer Open Platform. The system is builds on the work of GNP, Lighthouse and many more recent schemes. We also present results from various combinations of algorithms to perform the actual co-ordinate calculation based on GNP, Lighthouse and spring based systems and show our i...

Private social welfare expenditures were $680.7 billion in calendar year 1990. Viewed as a share of gross national product (GNP), private expenditures were 12.3 percent for calendar year 1990, while public expenditures for fiscal year 1990 were 19.1 percent of GNP (table 1). The private social welfare expenditure series was developed by the Social Security Administration (SSA) in 1955, with pro...

The graphite nanoplatelets (GNP) were treated by vapor-phase bromination. The increase in weight and atomic concentration of Br indicated the bromine uptake. The intercalation of Br between graphene layers of GNP was confirmed by the X-ray diffraction result, showing an increase in the interlayer spacing from 3.342 Å to 3.361 Å. Two types of bonds between C and Br were introduced simultaneously...

Spatiotemporal control of protein structure and activity in biological systems has important and broad implications in biomedical sciences as evidenced by recent advances in optogenetic approaches. Here, this study demonstrates that nanosecond pulsed laser heating of gold nanoparticles (GNP) leads to an ultrahigh and ultrashort temperature increase, coined as "molecular hyperthermia", which cau...

Solar-thermal technology based on phase change materials (PCMs) has received a lot of attention as cost-effective and practical way to overcome solar energy intermittency. However, weak photothermal conversion ability complex preparation processes have hindered the application PCMs. In this work, new approach for facile, uniform, firm assembly graphene nanoplatelet (GNP) through reaction oxide ...

Gadolinium (Gd) is a unique and powerful element in chemistry and biomedicine which can be applied simultaneously to magnetic resonance imaging (MRI), X-ray computed tomography (CT), and neutron capture therapy for cancers. This multifunctionality can be maximized using gadolinium oxide (Gd2O3) nanoparticles (GNPs) because of the large amount of Gd per GNP, making both diagnosis and therapy (i....

Hybrid materials combining gold nanoparticles (GNP) of variable diameter and an organic thin layer of photochromic diarylethenes were achieved. Solid-state photoswitching based on ring-closure/ring-opening reaction was carried out under alternate UV and visible irradiations. In addition to the spectral changes due to the photochromism itself, the surface plasmon resonance related to the GNP is ...

Using a gravity model, we estimate the magnitude of potential trade flows between Ireland and the five CEEC countries which are currently negotiating accession to the EU. We find that Irish exports were already close to their “normal” level in 1994, but that imports from the CEECs were still less than half of their potential size. The value of estimated potential trade corresponds to 0.8 per ce...
