Seed Transmission of <i>Pantoea stewartii</i> in Field and Sweet Corn (1998)

Seed transmission of Pantoea stewartii was evaluated by assays of more than 76,000 plants in greenhouse and field grow-out trials. Fourteen P. stewartii-infected seed lots were obtained from two dent corn inbreds and two sweet corn cultivars that were inoculated with either a rifampicin and nalidixic acid-resistant strain (rif-9A) or a wild-type strain (SS104) of P. stewartii. Four additional seed lots were collected from naturally infected inbreds. Percentages of infected kernels ranged from 0.8 to 72%, as determined by agar plating or by individual-kernel enzyme-linked immunosorbent assay (ELISA). Plants grown from this seed were assayed by a stem-printing technique that consisted of cutting and pressing a cross-section of each stem onto agar media. Prints were examined for development of P. stewartii colonies after 24 and 48 h. The transmission rate from seed produced on the inoculated plants was 0.066% (28 of 42,206 plants), based on all seedlings assayed. Transmission was estimated to be 0.14% from infected kernels. The transmission rate from seed produced on naturally infected plants was 0.0029% (1 of 34,924 plants), based on all seedlings, and 0.022% from infected kernels. Seed transmission occurred significantly less often (P = 0.034) from seed produced on naturally infected plants than from seed produced on inoculated plants, probably due to greater kernel damage caused by ear shank inoculation. The rarity of seed transmission of P. stewartii from heavily infected seed lots that would ordinarily be rejected due to poor germination suggests that the likelihood of seed transmission from good quality commercial seed corn is virtually nonexistent.

An Empirical Study of Trade Costs and FDI Location Choice——Based on the Perspective of Trade Costs' Effect on FDI Location Choice (2012)

The traditional gravity model suffers broad controversy when it is used to measure trade costs because it lacks of microscopic theory basis and often assumed the composition of trade costs in advance and ignore the impact of multilateral resistance.This paper uses a revised gravity model proposed by Novy(2008) to measure the trade costs between China and its 14 major trading partners during the period from 1985 to 2007,including the United States,Japan and so on.On this basis,we analyze the impact of trade costs on these countries' FDI location choice.The results show that the reduction of trade costs is an important factor that affects foreign investors to choose to invest in China.
Gelatinase B/matrix metalloproteinase‐9 provokes cataract by cleaving lens βB1 crystallin (2005)

Cataract is a common cause of blindness and results from destruction of the microarchitecture of the lens. It is observed in many genetic syndromes, infections, inflammatory diseases and during aging. Fluctuations in lens density and light scattering by altered refraction index form the physical basis for this process, but the pathogenesis is poorly understood. Increased levels of gelatinase B/matrix metalloproteinase-9 have been reported for cataract-associated disorders such as eye inflammation and diabetes. We demonstrate that incubation of lenses with gelatinase B leads immediately to cataract. In complete eye extracts, betaB1 crystallin was identified as the major gelatinase B substrate by combination of proteomics, mass spectrometry, and Edman degradation analysis. The cleavage of betaB1 crystallin was also observed in vivo after endogenous gelatinase B-induction by the chemokine granulocyte chemotactic protein-2 in wild-type mice but not in gelatinase B-/- mice.
Light-induced kinetic effects in molecular gases (1992)

Abstract Velocity-selective excitation can be achieved by tuning a narrow-band laser within the Doppler-broadened absorption profile of a gas. If the excitation modifies the kinetic properties of the molecules (e.g., the kinetic cross-sections or the molecule-surface interactions), the Maxwell velocity distribution will be distorted. This gives rise to a new class of kinetic effects that do not require external gradients to be imposed on the system; rather, the laser intensity and its gradient can be considered as thermodynamic forces. Examples are light-induced drift, surface light-induced drift and light-induced viscous flow. A phenomenological overview is given of the various light-induced kinetic effects which can arise in pure gases or mixtures. This includes effects resulting from velocity-selective excitation immediately followed by collisional de-excitation (‘velocity-selective heating’). The theoretical description of the various effects is briefly reviewed. Experiments are described which investigate these effects in molecular systems, where the excitation is ro-vibrational, and their results discussed. So far, data have been obtained for CH3F, NH3, CO2, OCS, CH3OH, CH3Br, SF6 and C2H4. Applications include determination of the vibrational-state dependence of intermolecular potentials, dependence of molecule-surface interactions upon the rotational state (J, M J), isotope separation, ortho-para conversion rates and possible astrophysical applications.

Web Application Tests with Selenium (2009)

Web applications tend to continuously evolve and thus need thorough, yet lean and automatic, regression testing. In this installment of Software Technology, Andreas Kornstadt and his colleagues describe automatic regression testing for Web applications that uses the Selenium testing framework. Selenium is portable open source software available for Windows, Linux, and Macintosh. Tests are written as HTML tables or in a number of programming languages and can run directly in most Web browsers. Andreas and his colleagues also provide many useful testing hints for practitioners. We look forward to hearing from both readers and prospective column authors about this column and the technologies we want to know more about.

In vitro evaluation of micronized low-substituted hydroxypropylcellulose as an insoluble swellable matrix for sustained-release tablets. (1991)

Micronized low-substituted hydroxypropylcellulose (L-HPC) was evaluated in vitro as an insoluble swellable matrix carrier for sustained-release tablets, using procainamide hydrochloride, theophylline and indomethacin. The amount of water-soluble fraction and the degree of aggregation of L-HPC particles in water increased with decreases in the particle size. The mechanisms of formation of non-disintegrating matrix tablets by micronized L-HPC are discussed on the basis of fast hydration and gel formation due to loss of the fibrous structural integrity of the cellulose polymer. Simple power law analysis suggests that the drug release from directly compressed L-HPC matrices is affected not only by polymer swelling but also by the drug solubility and the amount of soluble fraction in the matrices.
Requirement-Definition-Confirmation Modeling Approach for Identifying Uncertainties in Product Design Processes (2006)

Product design consists of multiple work elements and their interrelations, but it is often a tacit process in a practical design environment. In order to capture and formalize the work elements and their interrelations, it is useful to introduce a process modeling methodology and to analyze and synthesize the design process in an adequate way. This paper proposes a novel Requirement - Definition – Confirmation (RDC) Model for this purpose. The RDC Model describes a design process as the interrelation of three types of design elements: requirement, definition and confirmation. Use of this description can facilitate visualization of iterations, conflicts and uncertainties in the product design process. Such design qualities are often related to engineering risks, and can be used for supporting engineering decisions. We applied our RDC Model framework to automobile design and showed that RDC models effectively visualize the process quality and engineering risks.
Burial Diagenesis in Gulf Coast Pelitic Sediments (1970)

Abstract Subsurface samples of shales ranging in age from Pleistocene to Eocene obtained from five Gulf Coast oil wells were examined mineralogically and chemically to determine the nature and extent of burial diagenesis in pelitic sediments. Illite/montmorillonite dominates the mineralogy and undergoes a monotonic decrease in expandability from about 80 to a limit of 20 per cent montmorillonite layers with increasing depth. The interstratification changes from random to ordered at about 35 per cent expanded layers. Discrete illite and kaolinite phases are ubiquitous and judged detrital. The discrete illite (mica) content of the whole rock decreases with depth, while the kaolinite shows no systematic variation. Chlorite occurs in appreciable amounts in only one well and there only in samples from the shallow water facies. This chlorite is also considered detrital. Whole rock chemical analyses show no systematic variation with depth except for a decrease in calcium and magnesium caused by solution of carbonate. In contrast, potassium increases progressively with depth in the clay-size fraction, indicating a redistribution of potassium within the rock. Detrital illite (mica) seems to break down with increasing depth, thereby supplying potassium for interlayer fixation in illite/montmorillonite as the proportion of illite layers increases. The diagenetic reaction is independent of the geologic age of the sediments and of stratigraphic boundaries. Temperature seems to be more important than pressure in governing the reaction.
Thermal Initiation of MMA in High Temperature Radical Polymerizations (2005)

Abstract Summary: Several researches have dealt with the thermal initiation of methyl methacrylate (MMA) in the past. Some of them already discussed the presence of peroxide containing species that are formed from dissolved oxygen and the monomer itself as main reason for this initiation. However, a more detailed investigation as well as a kinetic description of this phenomenon is still due in literature. In this paper, the formation and decomposition of methyl methacrylate peroxides are described. MMA that has been in contact with air forms macromolecular peroxides at temperatures below 100 °C from physically dissolved oxygen. These peroxides have molecular weights of approximately 3 000–5 000 g · mol −1 , depending on the temperature during formation. Above this temperature, these peroxides decompose quickly and initiate the radical polymerization. Depending on the reaction conditions, monomer conversions from 15 to 30% are obtained. In combination with additional initiators, the MMA peroxides provoke an acceleration of the reaction rate and can also lead to bimodal molecular weight distributions. An analytical method based on UV‐spectrophotometry was developed for the quantification of the peroxide content in the monomer. The kinetic rate constants for the formation were determined in batch experiments with purified, air‐saturated monomer to be k f,0 = 6.28 · 10 7 l 2 · mol −2 · s and E A = 7.75 · 10 4 J · mol −1 . The decomposition rate constants were determined from batch dead‐end polymerizations and found to be k d,0 = 4.73 · 10 7 l · mol −1 · s −1 and E A = 8.56 · 10 4 J · mol −1 . magnified image
Molecular genetic anatomy of inter- and intraserotype variation in the human bacterial pathogen group A <i>Streptococcus</i> (2006)

In recent years we have studied the relationship between strain genotypes and patient phenotypes in group A Streptococcus (GAS), a model human bacterial pathogen that causes extensive morbidity and mortality worldwide. We have concentrated our efforts on serotype M3 organisms because these strains are common causes of pharyngeal and invasive infections, produce unusually severe invasive infections, and can exhibit epidemic behavior. Our studies have been hindered by the lack of genome-scale phylogenies of multiple GAS strains and whole-genome sequences of multiple serotype M3 strains recovered from individuals with defined clinical phenotypes. To remove some of these impediments, we sequenced to closure the genome of four additional GAS strains and conducted comparative genomic resequencing of 12 contemporary serotype M3 strains representing distinct genotypes and phenotypes. Serotype M3 strains are a single phylogenetic lineage. Strains from asymptomatic throat carriers were significantly less virulent for mice than sterile-site isolates and evolved to a less virulent phenotype by multiple genetic pathways. Strain persistence or extinction between epidemics was strongly associated with presence or absence, respectively, of the prophage encoding streptococcal pyrogenic exotoxin A. A serotype M3 clone significantly underrepresented among necrotizing fasciitis cases has a unique frameshift mutation that truncates MtsR, a transcriptional regulator controlling expression of genes encoding iron-acquisition proteins. Expression microarray analysis of this clone confirmed significant alteration in expression of genes encoding iron metabolism proteins. Our analysis provided unprecedented detail about the molecular anatomy of bacterial strain genotype-patient phenotype relationships.
Leaving Groups Prolong the Duration of 20S Proteasome Inhibition and Enhance the Potency of Salinosporamides (2008)

Salinosporamide A ( 1 (NPI-0052)) is a potent, monochlorinated 20S proteasome inhibitor in clinical trials for the treatment of cancer. To elucidate the role of the chlorine leaving group (LG), we synthesized analogues with a range of LG potentials and determined their IC 50 values for inhibition of chymotrypsin-like (CT-L), trypsin-like (T-L), and caspase-like (C-L) activities of 20S proteasomes. Proteasome activity was also determined before and after attempted removal of the inhibitors by dialysis. Analogues bearing substituents with good LG potential exhibited the greatest potency and prolonged duration of proteasome inhibition, with no recovery after 24 h of dialysis. In contrast, activity was restored after </=12 h in the case of non-LG analogues. Intermediate results were observed for fluorosalinosporamide, with poor LG potential. Kinetic studies indicate that 1 acts as a classical slow, tight inhibitor of the CT-L, T-L, and C-L activities and that inhibition occurs via a two-step mechanism involving reversible recognition followed by rate-limiting formation of a covalent enzyme-inhibitor complex.
Amplitude detection inside CMOS LC oscillators (2006)

In this paper we demonstrate that an intrinsic amplitude detector exists in negative resistance CMOS LC oscillators. The DC bias on the common-mode node in CMOS VCOs depends on the oscillation amplitude. Amplitude control loops can thus be built without a separate amplitude detector. Insights in possible AM to PM noise mechanisms are also derived
Using probabilistic confidence models for trust inference in Web-based social networks (2010)

In this article, we describe a new approach that gives an explicit probabilistic interpretation for social networks. In particular, we focus on the observation that many existing Web-based trust-inference algorithms conflate the notions of “trust” and “confidence,” and treat the amalgamation of the two concepts to compute the trust value associated with a social relationship. Unfortunately, the result of such an algorithm that merges trust and confidence is not a trust value, but rather a new variable in the inference process. Thus, it is hard to evaluate the outputs of such an algorithm in the context of trust inference. This article first describes a formal probabilistic network model for social networks that allows us to address that issue. Then we describe SUNNY, a new trust inference algorithm that uses probabilistic sampling to separately estimate trust information and our confidence in the trust estimate and use the two values in order to compute an estimate of trust based on only those information sources with the highest confidence estimates. We present an experimental evaluation of SUNNY. In our experiments, SUNNY produced more accurate trust estimates than the well-known trust inference algorithm TidalTrust, demonstrating its effectiveness. Finally, we discuss the implications these results will have on systems designed for personalizing content and making recommendations.

Notas a "Observaciones sobre el amor de transferencia", de Sigmund Freud (2012)

La trama del film “Un método peligroso” (Cronenberg, 2011) concluye en la primavera 1913. A inicios del año siguiente, Sigmund Freud se abocaría a la escritura de su artículo “Observaciones sobre el amor de transferencia”, publicado en 1915. Si bien no hay en el texto referencias a la polémica y ulterior ruptura con Jung, se puede inferir que su escritura fue motivada en parte por la errática conducta del analista suizo en el tratamiento de Sabine Spielrein. Dada la importancia de esta obra, ya canónica de la literatura psicoanalítica, reproducimos a continuación una conferencia inédita de Carlos Gutiérrez, que propone un seguimiento original del texto freudiano. Las citas del texto de Freud están tomadas de la traducción de López-Ballesteros y de Torres (O.C. Biblioteca Nueva). Para facilitar el seguimiento a los lectores no familiarizados con esta versión, se consigna también la referencia a la traducción de Etcheverry (O.C. Amorrortu).
Improved Measurement of Sulfur and Nitrogen Compounds in Refinery Liquids Using Gas Chromatography--Atomic Emission Detection (1998)

The measurement of sulfur and nitrogen compounds in refinery liquids is an important analysis for the petroleum industry. Gas chromatography with atomic emission detection (GC-AED) provides a useful means of selectively detecting these compounds. This article presents a GC-AED method optimized for the analysis of sulfur and nitrogen compounds in gasoline through diesel-range materials. By optimizing such parameters as element wavelength, detector gas flow rates, and chromatographic conditions, the selectivity in the presence of hydrocarbons is increased 10-fold for sulfur and by more than 100-fold for nitrogen. These gains in selectivity result in the ability to measure sulfur and nitrogen at low parts-per-million levels.
60μW SMR BAW oscillator designed in 65nm CMOS technology (2008)

This paper presents the simulation results of a BAW- based low power oscillator. The oscillator was designed using high-Q solidly mounted bulk acoustic wave resonators (SMR BAW) exhibiting quality factor around 2200. The oscillator is simulated using RF transistors of the CMOS 65 nm process from STMicroelectronics. The oscillator was optimized for low power purpose and consumes 50 muA from a 1.2 V source with phase noise performance of -124 dBc/Hz at 100 KHz offset. The impact of the bias current on phase noise, output voltage and oscillation frequency was also studied.
