Efficiency Enhancement of 250W Doherty Power Amplifiers Using Virtual Open Stub Techniques for UHF-band OFDM Applications (2006)

We propose a new efficiency enhancement method of Doherty power amplifiers (PAs) using virtual open stub techniques. In this method, we consider a peak amplifier's output line as a virtual capacitive open stub only seen at low power level. Using this method, we can transform the low power load impedance seen from the carrier amplifier into higher than the impedance of classical Doherty PA (>100ohm). The relations of the load impedance and the length of the virtual open stub are derived analytically. The developed UHF-band 250W 2-way Doherty PA has been achieved a drain efficiency of 42.1% and an intermodulation (IM) distortion of -27.3dBc at an output power of 44.1dBm (10dB output backed-off) under an integrated services digital broadcasting-terrestrial (ISDB-T) OFDM signal. To the best of our knowledge, these results are the highest backed-off efficiency ever reported among the over 40dBm saturation high power Doherty amplifiers

Effect of Dietary Fiber on Endogenous Nitrogen Flows in Lactating Dairy Cows (2002)

The effect of dietary fiber on endogenous N secretion was studied using a 15N isotope dilution technique in four fistulated Holstein cows. Two isonitrogenous diets differing only in fiber (NDF and ADF) content were used in a crossover design. One diet (HF) contained 37.4% NDF, while the other (LF) contained 23.3%. A new model was developed to estimate endogenous N secretions and losses for the preintestinal, intestinal, and the total sections of the gastrointestinal tract. Three precursor pools: TCA-soluble fraction of plasma, intestinal mucosa, and milk were compared. Although endogenous losses estimated with the model were numerically different for each precursor pool selected (TCA-soluble fraction > mucosa > milk), treatment effects were similar. As intestinal mucosa is probably closest to the precursor pool, these data are discussed. Non-urea N endogenous secretions contributed 13% of the duodenal N flow but were not affected by the fiber content of the diet. The nonurea N endogenous flow at the duodenum was comprised of approximately equal inputs from endogenous N direct, and that incorporated into the microbial biomass. Total endogenous N flows at the duodenum exceeded, by nearly twofold, estimated inputs of urea-N to microbial biomass. Metabolic fecal output averaged 17% of fecal N and was not affected by level of dietary fiber, but net losses from secretions occurring in the small intestine were higher with the low fiber diet. Overall, endogenous N secretions represented 30% of total digestive tract protein synthesis.
Diversity Among Isolates of<i>Bean pod mottle virus</i> (2002)

ABSTRACT Isolates of Bean pod mottle virus (BPMV), a member of the genus Comovirus, collected from soybean fields in Kentucky, Virginia, Arkansas, and Iowa were classified into two distinct subgroups, I and II, based on nucleic acid hybridization analysis using cloned cDNA probes to RNA-1 from BPMV strains K-G7 and K-Ha1. Slot blot hybridization analysis using cloned cDNA probes to RNA-2 from the same two strains (K-G7 and K-Ha1), however, revealed that some of the isolates, initially classified as belonging to subgroup I after analysis with RNA-1 probes, are in fact natural reassortants between the two strain subgroups. This was corroborated by nucleotide sequence analysis of full-length cDNA clones of both RNA-1 and RNA-2 from a putative reassortant strain (K-Ho1). These results indicate that BPMV strain diversity is more complex than initially anticipated, and that the use of cloned probes to both genomic RNAs during nucleic acid hybridization analysis is required to unravel the extent of such diversity. In a field plot experiment, BPMV isolates that belong to distinct strain subgroups induced symptoms that varied in severity and in the level of yield losses. In this regard, the reassortant strain K-Ho1 caused the most serious damage compared with four other BPMV isolates tested. Furthermore, the soybean alleles Rsv(1) and Rsv(4), known to confer resistance against Soybean mosaic virus, a member of the genus Potyvirus, did not provide any protection against BPMV. Additionally, we developed a reverse transcription-polymerase chain reaction procedure based on the sequence of a highly conserved region in the capsid polyprotein coding sequence that provides efficient and highly sensitive detection of all BPMV isolates tested, regardless of their strain classification.
Idiopathic Pulmonary Fibrosis (1976)

Idiopathic pulmonary fibrosis is a fatal disorder that starts as an alveolitis and progresses to interstitial fibrosis. Correlative morphologic, physiologic, and biochemical studies in 29 patients have shown that the inflammatory process in best followed by serial bronchoalveolar lavage and 67 Ga citrate scanning, and the fibrotic process is best followed by quantitation of the exercise-induced drop in arterial oxygen tension per unit of oxygen consumed. Although biopsies in idiopathic pulmonary fibrosis seem to show increased amounts of fibrotic tissue, biochemical studies suggest that the disease is probably one of collagen rearrangement rather than collagen increase. Perhaps becasue of this, peripheral lymphocytes of these patients recognize collagen as "non-self" and, when exposed to it in vitro, produce lymphokines and cell lysis. The fibrotic process is probably irreversible, but the inflammatory and immune processes that cause it may be amenable to therapy if diagnosed early.
Determination of optical properties of turbid media spanning visible and near-infrared regimes via spatially modulated quantitative spectroscopy (2010)

We present a novel, noncontact method for the determination of quantitative optical properties of turbid media from 430 to 1050 nm. Through measuring the broadband reflectance from an unknown sample as a function of the spatial frequency of the projected illumination patterns, the absolute absorption and reduced scattering coefficients can be calculated without a priori assumptions of the chromophores present. This technique, which is called spatially modulated quantitative spectroscopy (SMoQS), was validated through the quantification of optical properties of homogenous liquid phantoms with known concentrations of absorbers and scatterers. The properties of the phantoms were recovered across the range of values prepared with R(2) values of 0.985 and 0.996 for absorption and reduced scattering, respectively. A measurement was also performed on skin tissue as a demonstration of the method's performance in vivo. The resultant absorption spectrum was well described by a multichromophore fit, and the quantitative values for oxy- and deoxyhemoglobin, water, and melanin were within published ranges for skin.

Mode Coupling in Plasmonic Heterodimers Probed with Electron Energy Loss Spectroscopy (2017)

While plasmonic antennas composed of building blocks made of the same material have been thoroughly studied, recent investigations have highlighted the unique opportunities enabled by making compositionally asymmetric plasmonic systems. So far, mainly heterostructures composed of nanospheres and nanodiscs have been investigated, revealing opportunities for the design of Fano resonant nanostructures, directional scattering, sensing and catalytic applications. In this article, an improved fabrication method is reported that enables precise tuning of the heterodimer geometry, with interparticle distances made down to a few nanometers between Au-Ag and Au-Al nanoparticles. A wide range of mode energy detuning and coupling conditions are observed by near field hyperspectral imaging performed with electron energy loss spectroscopy, supported by full wave analysis numerical simulations. These results provide direct insights into the mode hybridization of plasmonic heterodimers, pointing out the influence of each dimer constituent in the overall electromagnetic response. By relating the coupling of nondipolar modes and plasmon-interband interaction with the dimer geometry, this work facilitates the development of plasmonic heterostructures with tailored responses, beyond the possibilities offered by homodimers.

Dispersion of Livestock Building Ventilation Using Windbreaks and Ducts (2001)

Installations of windbreak walls, short ducts, and stacks on livestock and poultrybuildings are described. With each, some vertical deflection of airflow (elevation of discharge)improves dispersion. In the case of windbreak walls downwind of exhaust fans, increasedmixing of odorous plumes into wind flow near the ground is achieved. Gaussian dispersiontheory shows that, except for tall stacks (greater than 15 m in height) or very close neighbors(e.g. within 0.5 km), dilution and dispersion using these devices is not expected to eliminateodor nuisances. Air cleaning or treatment within structures designed to enhance dispersionmay provide adequate reductions.

Scalable lineage capture for debugging DISC analytics (2013)

A fundamental challenge for big-data analytics is how to efficiently tune and debug multi-step dataflows. This paper presents Newt, a scalable architecture for capturing and using record-level data lineage to discover and resolve errors in analytics. Newt's flexible instrumentation allows system developers to collect this fine-grain lineage from a range of data intensive scalable computing (DISC) architectures, actively recording the flow of data through multi-step, user-defined transformations. Newt pairs this API with a scale-out, fault-tolerant lineage store and query engine.

The Impact Of Conjugate Vaccine On Carriage Of Haemophilus Influenzae Type B (1995)

Conjugate vaccines against Haemophilus influenzae type b (Hib) may modify Hib pharyngeal colonization. Hib colonization was compared in 371 infants and their families. In Oxfordshire, infants received PRP-T (polyribosylribitol phosphate conjugated to tetanus toxoid) and in Buckinghamshire they did not (controls). Infants were followed at 6, 9, and 12 months of age. Also, 6 unvaccinated Hib carriers were vaccinated and followed for 6 weeks. Hib acquisition was lower in vaccinees than controls (P < .01). During surveillance, 1.5% of vaccinees and 6.3% of controls carried Hib (P = .04). Among those with family Hib exposure, the carriage rates were 8.7% and 38.5% (P = .07), respectively. Hiv carriage rates were lower among vaccinees' unvaccinated siblings. Giving conjugate vaccine to a child carrying Hib did not rapidly terminate carriage. Thus, a primary means by which herd immunity to Hib is induced in a vaccinated population may be through reduction or delay in the initial acquisition of Hib.
Sequential Allylic Substitution/Pauson–Khand Reaction: A Strategy to Bicyclic Fused Cyclopentenones from MBH-Acetates of Acetylenic Aldehydes (2014)

An efficient approach for the construction of novel bicyclic fused cyclopentenones starting from Morita-Baylis-Hillman (MBH) acetates of acetylenic aldehydes with flexible scaffold diversity has been achieved using a two-step reaction sequence involving allylic substitution and the Pauson-Khand reaction. This strategy provided a facile access to various bicyclic cyclopentenones fused with either a carbocyclic or a heterocyclic ring system in good yield.

Heterojunction conception of n-La2Ti2O7/p-CuO in the limelight of photocatalytic formation of hydrogen under visible light (2014)

The heterojunction based photocatalyst between La2Ti2O7 and CuO is fabricated by a solid state reaction method. The prepared photocatalyst is characterized by X-ray diffraction, diffuse reflectance UV-vis spectroscopy, high resolution transmission electron microscopy, photoluminescence spectroscopy, X-ray photoelectron spectroscopy, BET surface area and photoelectrochemical measurements. The formation of the heterojunction is ascertained from XRD, HRTEM and XPS analysis. The activity of the photocatalyst is tested towards hydrogen evolution under visible light illumination. The conduction band of CuO is more positive than the hydrogen reduction potential, but after the formation of the heterojunction with La2Ti2O7, the system is able to evolve hydrogen under visible light. This is possible due to the alignment of the Fermi level which leads to the bending of the vacuum level during the formation of the heterojunction. As the vacuum level bends, the conduction and valence bands of La2Ti2O7 and CuO also bend w.r.t. the vacuum level. The bending of the conduction and valence bands make the hydrogen evolution possible. The hydrogen evolution mechanism is established with the help of photoelectrochemical measurements and X-ray photoelectron spectroscopy.

Electrical Characterization of Terphenyl-Based Molecular Devices (2011)

The electrical characteristics of phenylene-based molecular devices were assessed. The device consisted of nanogap electrodes and phenylene-based conjugated molecules. One nanogap electrode was obtained by the electromigration of a Au nanowire modified with a self-assembled monolayer (SAM) of 4,4- p -terphenyldithiol (TPDT). The other nanogap electrode was fabricated by the shadow evaporation of metals and subsequent deposition of SAM. Some devices obtained by the electromigration of Au nanowire modified with SAMs exhibited a large activation energy of electrical conduction of up to 0.26 eV. This large activation energy coincides with the intramolecular barrier estimated by ab initio molecular orbital calculations. On the other hand, the devices composed of shadow evaporated nanogaps and subsequently deposited TPDT exhibited a comparatively small activation energy. Neither device showed a clear gate effect with an electrical field up to 3 MV/cm. These results indicate that the electrical characteristics of molecular devices are affected by the fabrication process and the resultant molecule-electrode configuration.

Liver proteins as sensor of human malignancies and inflammation (2010)

In this review we would like to highlight the importance of acute-phase proteins as sensor of diseases. Both acute-phase protein levels and glycosylation have been reported to be altered in inflammation and other diseases including cancer. Factors that promote acute-phase protein synthesis and enhance the expression of specific glycosyltransferases, such as sialyltransferases and fucosyltransferases, may be up-regulated in some tumours and would explain the changes in acute-phase protein levels and the specific N-glycosylation modifications of some acute-phase proteins in cancer. However, further studies are required to define the potential clinical application of these acute-phase protein cancer-specific modifications as possible cancer diagnostic or monitoring tools.
Thermal and Mechanical Properties of Polyethylene/Doped-TiO<sub>2</sub>Nanocomposites Synthesized Using In Situ Polymerization (2011)

Ethylene polymerization was carried out using highly active metallocene catalysts (Cp 2 ZrCl 2 and Cp 2 TiCl 2 ) in combination with methylaluminoxane. Titanium (IV) oxide containing 1% Mn as dopant was used as nanofillers. The effects of filler concentration, reaction temperature, and pressure on the thermal and mechanical properties of polymer were analyzed. The improvement of nanoparticles dispersion in the polyethylene matrix was checked by WAXD. The thermal properties were analyzed using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The filler impact on the melting temperature of polyethylene synthesized using Cp 2 ZrCl 2 was very minimal which is due to the degree of short-chain branching. The ash content was also analyzed for each nanocomposite and found to be in line with the activity of the catalyst. There was a significant increase in the mechanical properties of the polyethylene by addition of filler.
