A low-complexity time-domain signal processing algorithm for N-continuous OFDM (2013)

N-continuous orthogonal frequency division multiplexing (OFDM) is a promising sidelobe suppression technique by enhancing the continuity between adjacent symbols with higher-order derivatives. However, it has high computational complexity due to the large-scale matrix operations in frequency domain. In this paper, a low-complexity time-domain signal processing (TDSP) algorithm for N-continuous OFDM is proposed. Based on linear combination of basis vectors, it utilizes small-scale matrix operations to generate the coordinates to construct N-continuous OFDM signal. Simulation results approve that the proposed algorithm achieves dramatic complexity reduction with identical sidelobe suppression and BER performance compared to conventional frequency-domain processed N-continuous OFDM.
<title>Further investigations into the use of linear and nonlinear mixing models for hyperspectral image analysis</title> (2002)

This paper presents the latest results of a series of experiments deigned to identify situations in which linear and nonlinear mixing models are expect to occur. It continues to investigate the possibility that there may be naturally occurring situation in which the typically used linear mixture model may not provide the most accurate spectrum. It has already been shown that for specific situations, in binary mixing cases, the nonlinear mixing model can produce more accurate endmember abundance estimates. These results are extended to include ternary and quaternary mixtures, as well as hyperspectral imagery collected over Cuprite, Nevada. In order to test these hypotheses, laboratory endmember and mixture data are collected in various scenarios for analysis. As shown in experiments, ternary and quaternary mixtures are more complicated than binary mixtures and the nonlinear mixing is more likely to occur in ternary and quaternary mixtures than in binary mixtures.
Cadmium telluride films by metalorganic chemical vapor depositiona) (1991)

Polycrystalline films of cadmium telluride (CdTe) have been deposited on glass and SnO2:F/glass substrates at 350–400 °C by the reaction of dimethylcadmium (DMCd) and diisopropyltellurium (DIPTe) in a hydrogen atmosphere. The DMCd/DIPTe molar ratio in the reaction mixture is an important factor affecting the deposition rate, conductivity type, and photoluminescence of deposited films. Photoluminescence measurements indicate that CdTe films deposited at 400 °C are of better quality than films deposited at 350 °C. The films deposited at 400 °C are p-type at DMCd/DIPTe molar ratios of 0.51 or less and are n-type at higher ratios. The structural, optical, and electrical properties of CdTe films have been characterized.
Adaptive exploiting user profile and interpretation policy for searching and browsing the Web on KODAMA system (2002)

The main thrust of the KODAMA research project is an investigation into novel ways of agentifying the Web based on the pre-existing hyper-link structure, and how this community of agents can automatically achieve and update its interpretation policies and cooperate with other agents to retrieve online distributed relevant information on the Web. The paper focuses on the use of the user interface agents in the KODAMA system for personalized information filtering and adapting, and discusses the method to update a user profile and interpretation policies adaptively for the user. This is an ideal and challenging environment for interface agents. The proposed idea is to employ an adaptive autonomous user interface agent that works for satisfying a user's information needs cooperatively with other agents in the KODAMA system, Web page agents and server agents.
Migration of Eosinophils through Basement Membrane Components <i>In Vitro</i> : Role of Matrix Metalloproteinase-9 (1997)

In general, inflammatory cells cross basement membranes by producing proteinases. To investigate the role of proteinases in eosinophil basement membrane migration, we studied peripheral blood eosinophils in Matrigel-coated chemotaxis chambers. Electron microscopy showed degradation of the Matrigel layer when eosinophils, added to the upper chamber, transmigrated the membrane in the presence of both platelet-activating factor (PAF) in the lower chamber and interleukin (IL)-5 in both chambers. In the absence of either or both PAF and IL-5, no changes occurred in the Matrigel layer. Matrigel transmigration of eosinophils induced by PAF and IL-5 was inhibited by 1,10-phenanthroline, batimastat, 3,4-dichloroisocoumarin, chymostatin, and a neutralizing antibody for the matrix metalloproteinase (MMP)-9, indicating that serine proteinase(s) and MMP, specifically MMP-9, were involved in the transmigration of eosinophils through Matrigel. In contrast, eosinophil migration through a bare membrane was not affected by batimastat. Using gelatin zymography and immunoblotting, MMP-9 was detected in the migration upper chamber supernatant of the eosinophil transmigration assay and in the conditioned medium of eosinophils. Release of MMP-9 by eosinophils was increased by IL-5, PAF, or both, but the substrate-degrading activity of MMP-9 was increased only in the presence of both IL-5 and PAF, indicating that the releasing and activating mechanisms of MMP-9 are involved in eosinophil basement membrane migration. This study implicates MMP-9 in basement membrane migration of eosinophils and suggests its involvement in inflammatory diseases where tissue eosinophilia plays a role.
Piezoelectricity of Ferroelectret Porous Polyethylene Thin Film (2009)

A ferroelectret porous polyethylene (Fp-PE) film with a thickness of 30 µm and a porosity of 58% was fabricated; its perpendicular piezoelectric constant d33 was 80 pC/N. In the Fp-PE film observed by atomic force microscopy (AFM), pores with a diameter of about 0.3 µm were almost homogeneously distributed. Moreover, from piezoresponse force microscopy (PFM), it was found that areas surrounding the pores shift in one direction following the application of ac voltage, but that areas far from the pores cannot move freely. These results indicate that the electrical charges trapped in areas surrounding the pores in the Fp-PE film play an important role in piezoelectricity.
INDEPENDENT AND SYNERGISTIC ACTIONS OF SOMATOMEDIN-C IN THE STIMULATION OF PROTEOGLYCAN BIOSYNTHESIS BY CULTURED RAT GRANULOSA CELLS (1986)

The role of somatomedin-C (Sm-C) in the regulation of granulosa cell proteoglycan biosynthesis was investigated in vitro in a primary culture of rat granulosa cells labeled with [35S]sulfate. Basal [35S]sulfate incorporation into extracellular proteoglycans was increased by 93 percent in response to treatment with highly purified Sm-C (50 ng/ml) by itself. Whereas treatment with a minimally effective dose of FSH (20 ng/ml) alone produced a 43 percent increase over basal levels in extracellular [35S]sulfate-labeled proteoglycans, concurrent treatment with Sm-C yielded a 2.7-fold amplification of the FSH effect. Qualitatively similar results were obtained when [35S]sulfate incorporation into cellular proteoglycans was determined, the latter accounting for approximately one half of the total radioactivity incorporated. Significantly, fractionation of the major extracellular proteoglycan species revealed FSH to favor the exclusive production of dermatan sulfate (1.6-fold increase), whereas Sm-C supported the simultaneous biosynthesis of both heparan and dermatan sulfate (2.5- and 1.8-fold increments, respectively). Moreover, Sm-C proved capable of diverting FSH-driven proteoglycan biosynthesis from the exclusive stimulation of dermatan sulfate towards the enhanced production of heparan sulfate over dermatan sulfate. These findings suggest that while Sm-C may synergize with FSH in stimulating granulosa cell proteoglycan biosynthesis, it is also able to act in tis own right to effect marked quantitative as well as qualitative alterations in proteoglycan economy. Given the possible role of proteoglycans in follicular antrum formation and follicular atresia, our findings raise the possibility that Sm-C of granulosa cell origin may partake in the growth as well as the demise of the developing ovarian follicle.
Precipitation of Carbides in a Ni-based Superalloy (2014)

Alloy B is relatively new precipitation hardening superalloy. It´s applications are in the hot sections of the aero engines, rocket nozzles, gas turbines and in the chemical and petro-leum applications. The alloy is characterized by keeping high strength at elevated tempera-tures and high creep resistance. It´s excellent mechanical properties and corrosion resis-tance are due to the balanced amount of the coherent γ' matrix, combined with other alloy-ing elements and carbides.There are three types of carbides which can be found in nickel-based superalloys: MC, M23C6 and M6C. Primary MC carbides act as source of carbon for the secondary carbides, which precipitate at the grain boundaries. They can have strengthening effect by hindering the movement of dislocations.In this work both simulation and experimental analysis are conducted in order to investi-gate the behaviour of the secondary carbides. JMatPro simulation is used to predict the behaviour of the material. Heat treatments are conducted at soak temperatures ranging from 920 °C to 1130 °C, with steps of 30 °C, and dwell times of 0.5, 1, 2 and 24 hours. Experimental methods included analysis at LOM, SEM, EDS, manual point counting and hardness tests.Main results show chromium rich M23C6 carbides are stable at lower temperature compared to molybdenum rich M6C. Both appear as fine and discrete particles at the grain boundaries at 1070 °C. This morphology is believed to be beneficial for the mechanical properties of the alloy. The volume fraction varies between 0.6 and 1.3%. Hardness values are relevant in the range of 920-1010 °C. Above this range there is sudden drop of the hardness

Embedding rectangular grids into square grids (1991)

It is shown that two-dimensional rectangular grids of large aspect ratio can be embedded into rectangular grids of smaller aspect ratios with small expansion and dilation. In particular, width can be reduced by a factor of up to two with optimal expansion, i.e. when the host rectangle is the smallest sufficient to contain the guest, and optimal dilation, i.e., two. A width reduction factor of three can be obtained with optimal expansion and dilation three. In general, any rectangular grid can be embedded into a square grid that is no more than unity larger on the side than the minimum possible, with dilation no more than three. These results improve on those previously obtained, in which dilation of better than 18 could not be guaranteed. They might be applicable to more complex grid embedding problems, such as embedding multidimensional grids into hypercubes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Visualization of surface charge distribution on insulating films using spatial optical phase modulation system (2002)

A visualization and a quantification technique of a latent electric charge image on a dielectric material has been developed by using Pockels effect and a computer image processing. An optical phase modulation technique and computer image lock-in amplifier processing were used to improve the signal to noise ratio. The measurement system has several improved performances: a sensitivity of surface charge of 1 nC cm/sup -2/; a spatial resolution of 200 /spl mu/m; and discrimination of the charge polarity. The basic principle of advanced electrooptic surface charge measurement is described and the typical surface charge distribution of a positive discharge streamer produced by an impulse high voltage (5 kV/sub peak/) is demonstrated. A comparison is also made between the modulation method and the nonmodulation method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Control of a Three Phase Inverter Feeding an Unbalanced Load and Operating in Parallel with Other Power Sources (2002)

A control for a three phase inverter, acting as a voltage source, is presented. The inverter is able to work in parallel with a constant-voltage constant-frequency system, as well as with other inverters or also in standalone. There’s no communication interface needed. The different power sources can share the load also under unbalanced conditions. To achieve this the frequency and the amplitude of the grid voltage can have small variations. By introducing a secondary control load sharing is even possible without frequency or amplitude deviations in steady-state. Measurements are presented to prove the good control behaviour.
Narrow-Band Absorption-Enhanced Quantum Dot/J-Aggregate Conjugates (2009)

We report narrow-band absorption enhancement of semiconductor nanocrystals via Förster resonance energy transfer from cyanine J-aggregates. These J-aggregated dyes associate electrostatically with short quantum-dot (QD) surface ligands in solution. Energy transfer efficiencies approach unity for this light sensitization and result in a 5-fold enhancement in the QD excitation near the J-aggregate absorption maximum. Because a thin layer of J-aggregates attenuates the same amount of light (at peak absorbance) as a far thicker film of monomer dye, these absorption-enhanced materials may have applications in light-sensitizing applications such as photodetection and optical down-conversion.
Toward a New Generation of World Climate Research and Computing Facilities (2010)

The impending threat of global climate change and its regional manifestations is among the most important and urgent problems facing humanity. Society needs accurate and reliable estimates of changes in the probability of regional weather variations to develop science-based adaptation and mitigation strategies. Recent advances in weather prediction and in our understanding and ability to model the climate system suggest that it is both necessary and possible to revolutionize climate prediction to meet these societal needs. However, the scientific workforce and the computational capability required to bring about such a revolution is not available in any single nation. Motivated by the success of internationally funded infrastructure in other areas of science, this paper argues that, because of the complexity of the climate system, and because the regional manifestations of climate change are mainly through changes in the statistics of regional weather variations, the scientific and computational requirements to predict its behavior reliably are so enormous that the nations of the world should create a small number of multinational high-performance computing facilities dedicated to the grand challenges of developing the capabilities to predict climate variability and change on both global and regional scales over the coming decades. Such facilities will play a key role in the development of next-generation climate models, build global capacity in climate research, nurture a highly trained workforce, and engage the global user community, policymakers, and stakeholders. We recommend the creation of a small number of multinational facilities with computer capability at each facility of about 20 petaflops in the near term, about 200 petaflops within five years, and 1 exaflop by the end of the next decade. Each facility should have sufficient scientific workforce to develop and maintain the software and data analysis infrastructure. Such facilities will enable questions of what resolution, both horizontal and vertical, in atmospheric and ocean models, is necessary for more confident predictions at the regional and local level. Current limitations in computing power have placed severe limitations on such an investigation, which is now badly needed. These facilities will also provide the world's scientists with the computational laboratories for fundamental research on weather–climate interactions using 1-km resolution models and on atmospheric, terrestrial, cryospheric, and oceanic processes at even finer scales. Each facility should have enabling infrastructure including hardware, software, and data analysis support, and scientific capacity to interact with the national centers and other visitors. This will accelerate our understanding of how the climate system works and how to model it. It will ultimately enable the climate community to provide society with climate predictions, which are based on our best knowledge of science and the most advanced technology.

Increased Activity of Constitutive Nitric Oxide Synthase in Cardiac Endothelium in Spontaneous Hypertension (1995)

The cNOS activity is upregulated in cardiac endothelial cells of genetically hypertensive rats. The high activity of cardiac cNOS is related to increased arterial pressure of these animals. We propose that in the heart, endothelial cells respond with a higher production of nitric oxide as a compensatory mechanism against high blood pressure and its damaging effects in this organ.
Mechanical milling of aluminum powder using planetary ball milling process (2012)

Mechanical alloying has recently attracted considerable attention as researchers strive to enhance nanocomposite properties and extend their utility. The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions (milling time, ball size, processing control agent (PCA) and speed) in mechanical alloying of aluminum powder to achieve particle size reduction with less contamination. Two types of PCA, i.e. stearic acid and methanol have been used and microstructure evolutions at different operating conditions were studied. It was shown that the optimized milling parameters for aluminium composite are 100 stainless steel ball (10 mm), 200 rpm rotation speed with direction reversal and 1 min pause time after every 15 min running time, under argon gas for 30 hr of milling.
