Constitutive Expression of <i>hrap</i> Gene in Transgenic Tobacco Plant Enhances Resistance Against Virulent Bacterial Pathogens by Induction of a Hypersensitive Response (2002)

Hypersensitive response-assisting protein (HRAP) has been previously reported as an amphipathic plant protein isolated from sweet pepper that intensifies the harpin(Pss)-mediated hypersensitive response (HR). The hrap gene has no appreciable similarity to any other known sequences, and its activity can be rapidly induced by incompatible pathogen infection. To assess the function of the hrap gene in plant disease resistance, the CaMV 35S promoter was used to express sweet pepper hrap in transgenic tobacco. Compared with wild-type tobacco, transgenic tobacco plants exhibit more sensitivity to harpin(Pss) and show resistance to virulent pathogens (Pseudomonas syringae pv. tabaci and Erwinia carotovora subsp. carotovora). This disease resistance of transgenic tobacco does not originate from a constitutive HR, because endogenous level of salicylic acid and hsr203J mRNA showed similarities in transgenic and wildtype tobacco under noninfected conditions. However, following a virulent pathogen infection in hrap transgenic tobacco, hsr203J was rapidly induced and a micro-HR necrosis was visualized by trypan blue staining in the infiltration area. Consequently, we suggest that the disease resistance of transgenic plants may result from the induction of a HR by a virulent pathogen infection.
Electrodynamic Tether Propulsion and Power Generation at Jupiter (1998)

This report discusses the results of a study performed to evaluate the feasibility and merits of using an electrodynamic tether (EDT) for propulsion and power generation for a spacecraft in the Jovian system. The environment of the Jovian system has properties which are particularly favorable for utilization of an EDT. Specifically, the planet has a strong magnetic field and the mass of the planet dictates high orbital velocities which, when combined with the planet&apos;s rapid rotation rate, can produce very large relative velocities between the magnetic field and the spacecraft. In a circular orbit close to the planet, tether propulsive forces are found to be as high as 50 N and power levels as high as 1 MW.
An improved Au/Be contact to <i>p</i>-type InP (1987)

An improved Ohmic contact for p-type InP has been demonstrated which is based on theAu/Be-Au material system but includes a chromium-barrier layer. This Au/Be-Cr-Au contact exhibits a lower specific-contact resistivity than that previously reported for the Au/Be-Au contact and does not degrade with time. The chromium barrier prevents indium out-diffusion into the gold (which has been observed even at room temperature) as well as reduces the phosphorus evaporation from the InP surface during the contact anneal. A specific-contact resistivity of 5×10−5 Ω cm2 has been observed for an anneal temperature of 410 °C and anneal times of 3–4 min. This value is believed to be the lowest reported value for an Ohmic contact on p-type InP which is doped in the 1×1018 cm−3 range. This contact has the advantage of not containing zinc which has a rapid diffusion rate and contaminates vacuum systems.

Pediococcus acidilactici MA18/5M is a commercially available probiotic that is widely used in swine, poultry, aquaculture feeds, and human dietary supplements. We prepared a genome sequence for this strain consisting of 2 scaffolds totaling 1,992,928 bases including gaps for a total of 3,346 bases and a G+C content of 42%.
Encapsulation of <i>Leiophron uniformis</i> by <i>Lygus lineolaris</i> and its relationship to host acceptance behavior (1989)

Abstract In no‐choice tests Leiophron uniformis (Gahan) from the Southwestern United States readily attacked their reported hosts, Lygus hesperus Knight, L. lineolaris (Palisot de Beauvois), L. elisus Van Duzee, and a previously unreported host, L. desertinus Knight. Only 6.7% of the L. lineolaris attacked were successfully parasitized compared to 84–87% parasitization of the other species. Such low parasitism of L. lineolaris was obtained with both laboratory‐reared and field‐collected parasitoids. Two factors caused the low rate of parasitism of L. lineolaris. (1) This host successfully encapsulates most of the L. uniformis eggs oviposited in them. This is the first time such an immune response to a parasitoid has been demonstrated in the Heteroptera. (2) Female L. uniformis oviposit less frequently into L. lineolaris than into other hosts. Résumé Etude de l'encapsulation de Leiophron uniformis par Lygus lineolaris et de ses relations avec le comportement d'acceptation de l'hôte L'aptitude du braconide Leiophron uniformis à parasiter les larves de quatre espèces nuisibles importantes de Lygus a été examinée. Les espèces de Lygus signalées comme hôtes de L. uniformis: L. hesperus, L. lineolaris, L. elisus , et un hôte jamais signalé, L. desertinus ont été exposées séparément à des femelles de braconide. Les larves des quatre espèces sont fortement attaquées. Seules 6,7% des larves de L. lineolaris attaquées ont été parasitées avec succès, contre 84 à 87% pour les trois autres espèces. Ce faible taux de parasitisme de L. lineolaris était le résultat aussi bien des attaques de parasitoïdes récoltés dans la nature qu'élevés au laboratoire. Les larves de L. hesperus et L. lineolaris attaquées par les femelles de L. uniformis ont été disséquées. Seuls 12,8% des larves de L. lineolaris contenaient des indices de pontes contre 83,7% pour celles de L. hesperus. 66,7% des oeufs trouvés dans L. lineolaris étaient encapsulés. C'est la première fois qu'une telle réponse immunologique a été observée chez un hétéroptère. Le faible nombre d'oeufs pondus par la femelle du braconide montre qu'elle est capable de détecter l'inadéquation de L. lineolaris comme hôte et d'éviter de gaspiller ses oeufs en utilisant peu les larves attaquées.

Analysis of multichannel narrow-band filters for image texture segmentation (1991)

A model for texture analysis and segmentation using multiple oriented channel filters is analyzed in the general framework. Several different arguments are applied leading to the conclusion that the two-dimensional Gabor filters possess strong optimality properties for this task. Properties of the multiple-channel segmentation approach are analyzed. In particular, perturbations of textures from an ideal model are found to have important effects on the segmentation that can usually be ameliorated by simply preceding the segmentation process by a logarithmic operation and using a low-pass postfilter prior to making region assignments. The difficult problems of space-variant textures and multiple component textures are also considered. Local spatial frequency estimation approaches are suggested that use the responses as constraints in estimating the locally emergent texture frequencies. Complex texture aggregates containing multiple shared frequency components can be analyzed if the textures are distinct and few in number.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis and characterization of new alternating, amphiphilic, comblike copolymers of poly(ethylene oxide) macromonomer and <i>N</i>‐phenylmaleimide (2004)

Abstract A surface‐active p ‐vinyl benzyloxy‐ω‐hydroxy‐poly(ethylene oxide) macromonomer containing 22 pendant structural units of ethylene oxide (St–PEO 22 ) was synthesized with an initiation method. Because of its solubility in a large variety of solvents, the free‐radical copolymerization with electron‐acceptor N ‐phenylmaleimide (NPMI) was performed at 60 °C in benzene and tetrahydrofuran (THF) as isotropic media and in a water–THF mixture or water as a heterogeneous medium. Oil‐soluble 2,2′‐azobisisobutyronitrile and water‐soluble 4,4′‐azobis(4‐cyanovaleric acid) were used as the initiators at fixed concentrations. Two different St–PEO 22 /NPMI comonomer ratios (1/1 and 3/7) at a fixed total comonomer concentration in the polymerization system were used. The structures, compositions, and microstructure peculiarities of the obtained alternating, amphiphilic, comblike copolymers were determined by NMR analysis. For the copolymers synthesized in hydrophilic media, differential scanning calorimetry showed, near the endothermic peak attributed to the melting of the poly(ethylene oxide) side chains, the presence of a second peak due to the partially ordered phase that could exist between the crystalline state and the isotropic melt. Also, the thermal stability of the obtained copolymers was studied with thermogravimetric analysis. © 2004 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 43: 479–492, 2005
Transforming Growth Factor-β1 Produced by Ovarian Cancer Cell Line HRA Stimulates Attachment and Invasion through an Up-regulation of Plasminogen Activator Inhibitor Type-1 in Human Peritoneal Mesothelial Cells (2003)

The processes of ovarian cancer dissemination are characterized by altered local proteolysis, cellular proliferation, cell attachment, and invasion, suggesting that the urokinase-type plasminogen activator (uPA) and its specific inhibitor (plasminogen activator inhibitor type-1 (PAI-1)) could be involved in the pathogenesis of peritoneal dissemination. We showed previously that expression of uPA and PAI-1 in the human ovarian cancer cell line HRA can be down-regulated by exogenous bikunin (bik), a Kunitz-type protease inhibitor, via suppression of transforming growth factor-beta1 (TGF-beta1) up-regulation and that overexpression of the bik gene can specifically suppress the in vivo growth and peritoneal dissemination of HRA cells in an animal model. We hypothesize that the plasminogen activator system in mesothelial cells can be modulated by HRA cells. To test this hypothesis, we used complementary techniques in mesothelial cells to determine whether uPA and PAI-1 expression are altered by exposure to culture media conditioned by HRA cells. Here we show the following: 1) that expression of PAI-1, but not uPA, was markedly induced by culture media conditioned by wild-type HRA cells but not by bik transfected clones; 2) that by antibody neutralization the effect appeared to be mediated by HRA cell-derived TGF-beta1; 3) that exogenous TGF-beta1 specifically enhanced PAI-1 up-regulation at the mRNA and protein level in mesothelial cells in a time- and concentration-dependent manner, mainly through MAPK-dependent activation mechanism; and 4) that mesothelial cell-derived PAI-1 may promote tumor invasion possibly by enhancing cell-cell interaction. This represents a novel pathway by which tumor cells can regulate the plasminogen activator system-dependent cellular responses in mesothelial cells that may contribute to formation of peritoneal dissemination of ovarian cancer.

Monolithic integration of both GaInAs photodiodes and GaInAsP lasers with impedance matching circuits for 6 GHz transmissions (2003)

The authors report the realization of monolithic impedance-matched lasers and photodiodes on InP substrates. The objective was to demonstrate the advantage of such an approach by using a transmission link operating at 6 GHz and 1.3 mu m. Starting from the analysis and modeling of discrete lasers and photodiodes fabricated in Thomson-CSF/LCR, the equivalent circuits of each device have been determined to design the associated impedance-matching cells.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Gb Virus C Infection is Associated with a Reduced Rate of Reactivation of Latent HIV and Protection against Activation-Induced T-Cell Death (2012)

GBV-C appears to inhibit immune activation and IL-2 signalling pathways, which might contribute to a reduction in reactivation of latent HIV from cellular reservoirs. In addition, GBV-C viraemia was associated with a reduction in activation-induced T-cell death. GBV-C-associated T-cell effects could contribute to the observed protective effect of GBV-C coinfection in HIV-infected individuals.

Metamorphic graded bandgap InGaAs-InGaAlAs-InAlAs double heterojunction p-i-I-n photodiodes (2002)

High-speed metamorphic double heterojunction photodiodes were fabricated on GaAs substrates for long-wavelength optical fiber communications. The high quality linearly graded quaternary InGaAlAs metamorphic buffer layer made possible the growth of excellent InGaAs-InGaAlAs-InAlAs heterostructures on GaAs substrates. The use of a novel double heterostructure employing an InGaAlAs optical impedance matching layer, a chirped InGaAs-InAlAs superlattice graded bandgap layer (SL-GBL), and a large bandgap i-InAlAs drift region enabled photodiodes to achieve a low dark current of 500 pA, a responsivity of 0.6 A/W, and a -3 dB bandwidth of 38 GHz at -5 V reverse bias for 1.55 /spl mu/m light. The effect of accumulated charges at the InGaAs-InAlAs heterointerface was examined through a comparison of the dark currents of InGaAs-InAlAs and InGaAs-InP abrupt single heterojunction photodiodes; to photodiodes with chirped InGaAs-InAlAs SL-GBLs. The charge accumulation effects observed in abrupt heterojunction devices were suppressed by including a chirped InGaAs-InAlAs SL-GBL between the InGaAs absorption layer and InAlAs drift layer. The effect of passivation techniques was evaluated by comparing dark currents of unpassivated photodiodes and photodiodes passivated with either polyimide or SiN/sub x/. The enhancement of photodiode bandwidth through the inclusion of a transparent large bandgap I-InAlAs drift region was verified by comparing the bandwidths of the P-i-I-N photodiodes that have I-InAlAs between i-InGaAs photoabsorption layer and N/sup +/ InAlAs cathode to conventional P-i-N photodiodes without a drift region.
Reducing power dissipation in low voltage flash memories (2002)

A new low voltage flash circuit model is presented. This SPICE model is used to identify techniques for reducing the average power dissipated in a flash memory during a programming cycle. The AND flash memory cell is used in this analysis. For a selected bitcell in a NOR block, the power dissipated is dominated by a band-to-band transient current. SPICE simulations show that this power can be reduced by decreasing the charge pump's slew rate and the erase threshold voltage. In an unselected bitcell, the power dissipated is the sum of band-to-band and drain charging currents. Simulations show that this power can be reduced by increasing the positive word line bias applied to unselected bitcells in the NOR block.
A-78773: a selective, potent 5-lipoxygenase inhibitor. (1993)

The potency and selectivity of A-78773, a newly discovered 5-lipoxygenase inhibitor, were examined. The compound was significantly more potent than zileuton in inhibiting leukotriene formation in cell free lysates and in isolated human neutrophils. A-78773 inhibited a RBL cell lysate 5-lipoxygenase at concentrations 2 orders of magnitude lower than those required to inhibit rabbit reticulocyte 15-lipoxygenase or human platelet 12-lipoxygenase. The compound was also a potent, long lasting, orally active inhibitor of leukotriene formation ex vivo in dogs and in vivo in the rat. In experiments where leukotriene formation was completely inhibited, no increase in eicosanoids from other pathways was observed. A-78773 should prove to be a valuable clinical tool in treating leukotriene mediated diseases.
Deep Learning with Hierarchical Convolutional Factor Analysis (2013)

Unsupervised multilayered (“deep”) models are considered for imagery. The model is represented using a hierarchical convolutional factor-analysis construction, with sparse factor loadings and scores. The computation of layer-dependent model parameters is implemented within a Bayesian setting, employing a Gibbs sampler and variational Bayesian (VB) analysis that explicitly exploit the convolutional nature of the expansion. To address large-scale and streaming data, an online version of VB is also developed. The number of dictionary elements at each layer is inferred from the data, based on a beta-Bernoulli implementation of the Indian buffet process. Example results are presented for several image-processing applications, with comparisons to related models in the literature.
The Delta-t transport protocol: features and experience (2003)

With the advent of new high performance networks and distribution systems there is renewed interest in transport protocol designs that can support both request/response and stream styles of communication. The author examines Delta-t, a transport protocol designed to meet such goals. Delta-t's main contribution is in the area of connection management, where it achieves hazard-free connection management without explicit packet exchanges. The author reviews Delta-t's features and connection management in general and outlines some lessons useful for the implementation of high-performance networks.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Platelet-activating factor receptor (PAF-R)-dependent pathways control tumour growth and tumour response to chemotherapy (2010)

We suggest that PAF-R-dependent pathways are activated during experimental tumour growth, modifying the microenvironment and the phenotype of the tumour macrophages in such a way as to favour tumour growth. Combination therapy with a PAF-R antagonist and a chemotherapeutic drug may represent a new and promising strategy for the treatment of some tumours.
