Radial basis function neural network algorithm for adaptive beamforming in cellular communication systems (2002)

A smart antenna based on a neural network implementation of the optimum Wiener solution for the problem of adaptive interference nulling using circular arrays is presented. Modem cellular satellite mobile communications systems and GPS systems suffer from different sources of interference which limit system capacity. This paper develops a fast tracking system to constantly track the mobile users, and then adapt the radiation pattern of the antenna to direct multiple narrow beams to desired users and nulls to sources of interference. The computation of the optimum weights is viewed as a mapping problem which can be modeled using a three-layer radial basis function neural network (RBFNN) trained with input/output pairs. The results obtained from this network are in excellent agreement with the Wiener solution. It is found that networks implementing these functions are successful in tracking mobile users as they move across the antenna's field of view.
Cardiac glycosides, phenolic compounds and antioxidant activity from plant cell suspension cultures of Thevetia peruviana (2017)

Se establecieron cultivos en suspensión de la especie vegetal Thevetia peruviana en oscuridad, durante 19 días, para estudiar el comportamiento cinético de producción de biomasa, consumo de sustrato, producción de glicósidos cardiotónicos, polifenoles, especies reactivas de oxígeno y actividad antioxidante. Los resultados mostraron una alta producción de biomasa (18,80g PS/L), al igual que consumo total de sacarosa, a los 7 días de cultivo. Se observó un consumo preferencial de glucosa sobre fructosa durante todo el cultivo. La producción de glicósidos cardiotónicos intracelulares alcanzó valores de 2,58mg ED/g PS, al día 19. La mayor producción extracelular (6,19mg ED/L), se alcanzó entre los días 2 y 7. El mayor contenido de compuestos fenólicos extracelular fue de 80,61 ± 5,16mg GAE/L, en el día 7. El contenido de compuestos fenólicos intracelulares incrementó a 2,76 ± 0,14mg AGE/gPF, al día 7 y se mantuvo constante, hasta el día 19. La producción de EROs, al día 7, puede estar relacionada con el consumo total de sacarosa y glucosa. El coeficiente de correlación producto-momento de Pearson (ρ) indicó que los compuestos fenólicos en cultivos celulares en suspensión de T. peruviana eran los responsables de la actividad antioxidante observada. En conjunto, estos resultados brindan las primeras bases relacionadas al comportamiento metabólico de cultivos celulares en suspensión, de T. peruviana.

Novel, one-step synthetic routes for the preparation of 1-methyl-2,4,5-trinitroimidazole (MTNI) are described. In addition, a new, molten-state nitration method for the synthesis of 1-methyl-2,4,5-trinitroimidazole is developed.
Low temperature processing of indium-tin-zinc oxide channel layers in fabricating thin-film transistors (2011)

The authors report on the fabrication of thin-film transistors (TFTs) using indium-tin-zinc oxides (ITZOs) as active channel layers. Transparent amorphous ITZO semiconductors were deposited at room temperature by rf-magnetron sputtering, followed by an annealing treatment at 100 °C. The electrical properties of the ITZO channel layers deposited at room temperature using rf-magnetron sputtering were investigated by controlling the oxygen partial pressure during deposition and introducing postannealing treatments. The devices operated in an n-type enhancement mode exhibited a clear pinch-off behavior and had an on-to-off ratio of ∼108 with a low off current of 3×10−13 A. A field-effect mobility of 17 cm2/V s and a subthreshold slope of 0.5 V/decade were extracted from the device characteristics. These results suggest that ITZO semiconductors show potential as channel materials that are applicable in flexible transparent TFTs.
Evaluation of the mathematical and economic basis for conversion processes in the LEAP energy-economy model (1982)

An evaluation was made of the mathematical and economic basis for conversion processes in the LEAP energy-economy model. Conversion processes are the main modeling subunit in LEAP used to represent energy conversion industries and are supposedly based on the classical economic theory of the firm. The study arose out of questions about uniqueness and existence of LEAP solutions and their relation to classical equilibrium economic theory. An analysis of classical theory and LEAP model equations was made to determine their exact relationship. The conclusions drawn from this analysis were that LEAP theory is not consistent with the classical theory of the firm. Specifically, the capacity factor formalism used by LEAP does not support a classical interpretation in terms of a technological production function for energy conversion processes. The economic implications of this inconsistency are suboptimal process operation and short term negative profits in years where plant operation should be terminated. A new capacity factor formalism, which retains the behavioral features of the original model, is proposed to resolve these discrepancies.
Spontaneous Symmetry Breaking in a Polariton and Photon Laser (2012)

We report on the simultaneous observation of spontaneous symmetry breaking and long-range spatial coherence both in the strong- and the weak-coupling regime in a semiconductor microcavity. Under pulsed excitation, the formation of a stochastic order parameter is observed in polariton and photon lasing regimes. Single-shot measurements of the Stokes vector of the emission exhibit the buildup of stochastic polarization. Below threshold, the polarization noise does not exceed 10%, while above threshold we observe a total polarization of up to 50% after each excitation pulse, while the polarization averaged over the ensemble of pulses remains nearly zero. In both polariton and photon lasing regimes, the stochastic polarization buildup is accompanied by the buildup of spatial coherence. We find that the Landau criterion of spontaneous symmetry breaking and Penrose-Onsager criterion of long-range order for Bose-Einstein condensation are met in both polariton and photon lasing regimes.
Zinc Deficiency in Murine Milk Underlies Expression of the <i>Lethal Milk</i> ( <i>lm</i> ) Mutation (1978)

The inability of nursing pups to survive on milk of mice homozygous for the recessive mutation, lethal milk (lm), is correlated with a reduction in zinc levels of both milk and pup carcass. Administration of zinc to pups nursing on lmlm dams reduces the observed mortality and morbidity. It is suggested that lm alters zinc transport from maternal blood to milk and that its study may provide useful information for understanding the rare human disease, acrodermatitis enteropathica.

Vinylidene Transition‐Metal Complexes, XVII. — Synthesis of trans ‐[IrCl(=C=CH 2 )(PR 3 ) 2 ] (PR 3 = PMe t Bu 2 , PPh 3 ), [IrHCl(CCPh)(PMe 2 t Bu) 3 ], and of some Dihydridoiridium(III) Complexes [IrCl(C 8 H 14 ) 2 ] 2 ( 1 ) reacts with PMe t Bu 2 in the presence of H 2 to give [IrH 2 Cl(PMe t Bu 2 ) 2 ] ( 2 ). Treatment of 2 with acetylene yields the vinylidene complex trans ‐[IrCl(=C=CH 2 )‐(PMe t Bu 2 ) 2 ] ( 3 ). The reaction of 1 with PMePh 2 or PMe 2 t Bu in the presence of H 2 leads to the formation of fac ‐[IrH 2 Cl(PR 3 ) 3 ] ( 4a , 5a ), which on warming to 60°C rearrange to give the more stable mer isomers 4b , 5b . Treatment of 1 with PMePh 2 or PMe 2 t Bu and phenylacetylene affords the hydrido(phenyl‐ethynyl)iridium(III) compounds mer ‐[IrHCl(CCPh)(PR 3 ) 3 ] ( 8, 9 ), which could not be converted by phosphine elimination to the corresponding (phenylvinylidene)iridium complexes. The synthesis of trans ‐[IrCl(=C=CH 2 )(PPh 3 ) 2 ] ( 11 ) has been achieved by CO abstraction from [IrHCl(CCH)(CO)(PPh 3 ) 2 ] ( 13 ) by using trimethylamine oxide.

Ultra-compact high speed mmW transceiver using GaN Power Amplifier technology (2015)

Recent advances in high power millimeter wave (mmW) Gallium Nitride (GaN) technology combined with advances in high-speed modem modulation efficiency has enabled the development of an ultra-compact long range mmW transceiver. This paper outlines the various aspects of this transceiver front-end development including the compact mmW antenna, integrated mmW circuitry, and single-chip GaN Power Amplifier (PA). Data links configured using this transceiver were evaluated in-chamber and outdoors between two mountain tops. Data rates up to 6.5 Giga-bits-per-second (Gbps) were demonstrated.
QT dispersion and electrical heart field morphology in patients treated with dosulepin. (2004)

The aim of the study was to detect the changes of QT dispersion (QTd) due to cardiotoxicity of tricyclic antidepressant dosulepin. Electrocardiographic and vectorcardiographic recordings were obtained using Cardiag 112.2 diagnostic system from 28 psychiatric outpatients treated with prophylactic doses of dosulepin and compared to those obtained from 37 healthy volunteers. From these recordings following parameters were evaluated: QTd, spatial QRS-STT angle and amplitude of T-wave. The acquired data were correlated with the dosulepin plasma levels using Spearman's rank order correlation test. The average QTd (+/-S.D.) in the dosulepin group was significantly higher (70+/-21 ms) than that in the control group (34+/-12 ms) (P<0.001). Moreover, the correlation between QTd and the dosulepin plasma levels was highly significant (r = 0.7871, P<0.001). Similar results were obtained when QTc dispersion was used. On the contrary, the QRS-STT space angle did not correlate with the dosulepin plasma levels. Furthermore, the T-wave amplitude was not significantly correlated to the QT-interval. Thus we can conclude that the QT dispersion could be used as a simple marker of the dosulepin effect on the myocardium.

Density Functional Theory Comparison of Water Dissociation Steps on Cu, Au, Ni, Pd, and Pt (2009)

We report a plane-wave, supercell density functional theory (DFT) investigation of the adsorption and dissociation of water on (111) surfaces of Cu, Au, Pt, Pd, and Ni, five metals of potential interest in the context of water gas shift (WGS) catalysis. Binding energies, preferred adsorption sites, and configurations for H2O and its dissociation products (OH, H, and O) are determined on all five metals, as are the minimum energy paths (MEPs) and activation energies for H−OH and O−H dissociation. Results are compared with the diverse computational literature on H2O dissociation over these metals. Both dissociation steps are found here to be highly endothermic on Au(111) and slightly endothermic on Pt(111) and Pd(111). The first H abstraction from adsorbed H2O is exothermic on Cu(111) and Ni(111), but subsequent OH dissociation is endothermic on Cu(111) and slightly exothermic on Ni(111). Using a simple Langmuir equilibrium model, we show that under the high H2 background pressures typical of low-temperature WGS, the surface coverage of OH is expected to be several orders of magnitude higher than that of O, consistent with a significant role of OH in surface CO oxidation.
Naturally Acquired Human Plasmodium knowlesi Infection (2008)

We report a case of naturally acquired Plasmodium knowlesi in Singapore, a malaria-free country. Diagnosis was confi rmed by PCR with validated species-specifi c primers. In industrialized countries, free-ranging primates are a potential source of P. knowlesi human infection. P. knowlesi infection is a differential diagnosis of febrile illness acquired in Singapore.
The Eventual Intracellular Destruction of Staphylococci by Mononuclear Cells (1962)

SUMMARY: It was found that Staphylococcus aureus usually survived within monoeytes of normal rabbits for several hours without multiplication, but were eventually destroyed. However, there was variation in the intracellular behaviour in leucocytes of different rabbits in that cells from some donors began the slow destruction of the staphylococci shortly after phagocytosis. In many of these experiments streptomycin was incorporated in the tissue-culture medium to suppress the extracellular multiplication of staphylococci. Interference by streptomyein with the intracellular be-haviour of staphylococci was considered as minimal on the basis that the intra ellular survival was not influenced by different concentrations of the drug in the tissue-culture medium nor did incubation of the cells in the antibiotic before infection alter the subsequent survival of the organisms.
Hydrophobic matrix-free graphene-oxide composites with isotropic and nematic states (2016)

We demonstrate a novel route to synthesise hydrophobic matrix-free composites of polymer-grafted graphene oxide (GO) showing isotropic or nematic alignment and shape-memory effects. For the first time, a cationic macroinitiator (MI) has been immobilised on anionic GO and subsequently grafted with hydrophobic polymer grafts. Dense grafts of PBA, PBMA and PMMA with a wide range of average graft lengths (MW: 1-440 kDa) were polymerised by surface-initiated controlled radical precipitation polymerisation from the statistical MI. The surface modification is designed similarly to bimodal graft systems, where the cationic MI generates nanoparticle repulsion, similar to dense short grafts, while the long grafts offer miscibility in non-polar environments and cohesion. The state-of-the-art dispersions of grafted GO were in the isotropic state. Transparent and translucent matrix-free GO-composites could be melt-processed directly using only grafted GO. After processing, birefringence due to nematic alignment of grafted GO was observed as a single giant Maltese cross, 3.4 cm across. Permeability models for composites containing aligned 2D-fillers were developed, which were compared with the experimental oxygen permeability data and found to be consistent with isotropic or nematic states. The storage modulus of the matrix-free GO-composites increased with GO content (50% increase at 0.67 wt%), while the significant increases in the thermal stability (up to 130 °C) and the glass transition temperature (up to 17 °C) were dependent on graft length. The tuneable matrix-free GO-composites with rapid thermo-responsive shape-memory effects are promising candidates for a vast range of applications, especially selective membranes and sensors.
Corticosteroids Induce Intracellular Interleukin-1 Receptor Antagonist Type I Expression by a Human Airway Epithelial Cell Line (1996)

Interleukin-1 (IL-1) is an important proinflammatory cytokine which may contribute to the pathogenesis of inflammatory airway disorders, such as asthma and cystic fibrosis. Interleukin-1 receptor antagonist (IL-1ra) is a naturally occurring IL-1 inhibitor which binds to IL-1 receptors without inducing agonist activity. Three IL-1ra isoforms have been identified: secreted IL-1ra (sIL-1ra), which is preferentially expressed by-inflammatory cells; intracellular IL-1ra (iIL-1ra) type I, which lacks a signal peptide and is preferentially expressed by epithelial cells; and iIL-1ra type II, which is identical to iIL-1ra type I except for the insertion of an additional 21 amino acids. The goal of this study was to assess whether airway epithelial cell iIL-1ra type I production can be regulated by corticosteroids. First, using reverse transcription-polymerase chain reaction (RT-PCR) and immunoblotting, we confirm that normal human bronchial epithelial (NHBE) cells and a human pulmonary mucoepidermoid carcinoma cell line (NCI-H292) express intracellular IL-1ra type I messenger RNA (mRNA) and protein. Second, using immunoblotting and ELISA, we report that dexamethasone induces time- and concentration-dependent increases in iIL-1ra type I protein within NCI-H292 cell lysates. Lastly, utilizing a ribonuclease protection assay, we report that dexamethasone induces concentration-dependent increases in iIL-1ra type I mRNA levels in NCI-H292 cells. These data suggest that corticosteroid-mediated induction of iIL-1ra type I mRNA and protein by human bronchial epithelial cells represents a novel mechanism by which IL-1-mediated airway inflammatory events might be regulated.
Plasmid transfer for enhancing degradation capabilities. (1995)

The kinetics of plasmid conjugation for the TOL and RP4 plasmids depend strongly on the donor cells' specific growth rate and substrate concentration, both of which determine the cells' energy availability. Although transfer rates can be large when energy availability is high, normal biological processes have low energy availability. Therefore, we propose and evaluate preliminarily a simple scheme to create a small zone of high energy availability.
[Conservative treatment of sub-clinical noninfiltrating cancers of the breast (102 EOA in situ, TONO)]. (1995)

102 patients with sub-clinical intra ductal non invasive breast cancer (T0N0) treated by limited surgery and curative radiation therapy. Follow-up ranged from 2 to 10 years with a median follow-up of 59 months. The long term survival rate of this therapeutic approach, consisting of simple excision without any adjuvant treatment and radical mastectomy was close to 100%. The actuarial local recurrence rate was only 8.6% at 10 years (confidence interval: 4.6 to 12.6%), which strongly suggests that radiation therapy is active on multicentric foci. Salvage surgery could be performed in every case of local recurrence. The survival rate of in situ breast cancer (T0N0) treated by conservative radio-surgery is comparable to that of radical mastectomy, while cosmetic results and psychological impact appear to be better for the conservative technique (breast preservation rate = 91 to 96%).
The Impact of Poultry Manure on Water Quality Using Tile Drained Field Plots and Lysimeters (2004)

A six-year study was conducted to determine the effects of four experimental treatments[168 kg N/ha from poultry manure (PM), 168 kg N/ha from urea-ammonium nitrate (UAN), 336 kgN/ha from poultry manure (PM2), and 0 kg N/ha (control treatment)] on corn and soybean yields,grain quality, corn stalk N, soil NO3-N, soil PO4-P, subsurface tile drain water quality, runoff waterquality, and bacteria concentrations in subsurface drain and runoff waters. Eleven field plots wereplanted to a corn-soybean rotation, while six lysimeters were planted to continuous corn.Conclusions indicate that the PM treatment is the better choice in applying nutrients to fields becauseof high yields, which were significantly higher than the UAN treatment and similar to the higher ratePM2 treatment. In addition, the PM treatment resulted in reduced levels of soil NO3-N levelscompared to UAN treatment and lower soil PO4-P trends compared to the PM2 treatment. Also, thePM treatment resulted in reduced NO3-N losses in subsurface drain water as compared to the UANand PM2 treatments. Bacteria concentrations in subsurface drain and runoff waters from the PM2treatment were higher in comparison with the UAN and PM treatments. Additionally, the bacteriaconcentrations from the PM2 treatment were double the concentrations of the PM treatment. Thus,as long as the poultry manure is applied at reasonable nitrogen rates (of 168 kg N/ha), it makes agood soil amendment, gives better crop yields, and reduced NO3-N concentrations in subsurfacedrain water compared to 168 kg N/ha from UAN and 336 kg N/ha from poultry manure.
<i>In Vivo</i> Application of an RNAi Strategy for the Selective Suppression of a Mutant Allele (2010)

Gene therapy for dominantly inherited diseases with small interfering RNA (siRNA) requires mutant allele-specific suppression when genes in which mutation causes disease normally have an important role. We previously proposed a strategy for selective suppression of mutant alleles; both mutant and wild-type alleles are inhibited by most effective siRNA, and wild-type protein is restored using mRNA mutated to be resistant to the siRNA. Here, to prove the principle of this strategy in vivo, we applied it to our previously reported anti-copper/zinc superoxide dismutase (SOD1) short hairpin RNA (shRNA) transgenic (Tg) mice, in which the expression of the endogenous wild-type SOD1 gene was inhibited by more than 80%. These shRNA Tg mice showed hepatic lipid accumulation with mild liver dysfunction due to downregulation of endogenous wild-type SOD1. To rescue this side effect, we generated siRNA-resistant SOD1 Tg mice and crossed them with anti-SOD1 shRNA Tg mice, resulting in the disappearance of lipid accumulation in the liver. Furthermore, we also succeeded in mutant SOD1-specific gene suppression in the liver of SOD1(G93A) Tg mice, a model for amyotrophic lateral sclerosis, using intravenously administered viral vectors. Our method may prove useful for siRNA-based gene therapy for dominantly inherited diseases.
Dynamic Response of Airplanes in Ground Operation (1974)

This investigation deals with deterministic and stochastic analyses of dynamic response of airplanes to runway unevenness. After a brief review of various methods for runway unevenness representation, a new approach of power spectral representation of sectional ergodic runway is presented. This new method, while keeping the computational expedience of power spectral density techniques, has the important feature that the local uneven nature of runways can be revealed. Two complementary approaches are used to obtain dynamic response. They are time-history analysis and power spectral analysis. The mathematical idealization of airplanes used in analysis can take account of the nonlinear behavior of the landing gear systems and the flexural nature of the free-free airframe. The analysis of the dynamic response of the Boeing 707 airplane to a severely uneven runway is taken as an example solution in order to illustrate some applications of the methods. Finally, some of the more significant findings of this investigation are summarized.
