Reaction of families and lines of melon to powdery mildew (2011)

Powdery mildew, caused by Podosphaera xanthii, is an important disease of melon in the Brazilian Northeast. The objective of this work was to evaluate the reaction of families, lines and cultivars of melon to P. xanthii. Two experiments in simple lattice were carried out under field conditions in the municipalities of Mossoró and Baraúna to evaluate 144 families. In a greenhouse, an experiment was carried out in a completely randomized design to evaluate 19 lines and the cultivars Yellow Queen, Chilton and Hy Mark. Disease was assessed by a severity scale. There was genetic variability among families. The families 4, 5, 11, 14, 18, 23, 33, 42, 101, 112 and 140 were identified in both sites as resistant. The lines LOF-027, LOF-105, LPS-124, MEL-008 and cultivar Chilton showed resistance to race 1 of the fungus.
Decentralized Consensus Algorithm with Delayed and Stochastic Gradients (2018)

We analyze the convergence of a decentralized consensus algorithm with delayed gradient information across the network. The nodes in the network privately hold parts of the objective function and collaboratively solve for the consensus optimal solution of the total objective while they can only communicate with their immediate neighbors. In real-world networks, it is often difficult and sometimes impossible to synchronize the nodes, and therefore they have to use stale gradient information during computations. We show that, as long as the random delays are bounded in expectation and a proper diminishing step size policy is employed, the iterates generated by the decentralized gradient descent method converge to a consensual optimal solution. Convergence rates of both objective and consensus are derived. Numerical results on a number of synthetic problems and real-world seismic tomography datasets in decentralized sensor networks are presented to show the performance of the method.
Imaging through Gas-Filled Sediments with Land 3C Seismic Data (2007)

B022 Imaging through Gas-Filled Sediments with Land 3C Seismic Data Y. Li* (BGP) P. Sun (BGP) D. Tang (BGP) Y. He (BGP) H. Chen (BGP) & Y. Yue (BGP) SUMMARY It has been proved in many 4C OBC cases that gas cloud imaging can be improved with converted wave (Li et al. 2001) but few cases have been demonstrated in land 3-C exploration. This paper shows how multi-component (3-C) land data with dynamite source is used to image sub-gas-cloud sediments in CS gas field China. The conventional P-wave data provides unreliable structural images and the interpretation is dubious in an
Contributions of Functional Magnetic Resonance in the Field of Psychological Treatments with Virtual Reality (2010)

Many studies have been developed using brain imaging methods to investigate psychological disorders. On the other hand, there are many studies that make use of virtual reality (VR) to simulate a real condition during psychological treatments. In this research, we plan to analyze brain activity during the exposure to a virtual environment related to phobias. Our first goal is to study the possibility of activating brain areas related to phobias, specifically phobias to small animals (spiders and cockroaches), using virtual reality as stimulus, while the patient is inside a functional magnetic resonance imaging (fMRI) machine. The second goal of the research is to analyze if there are differences in the activated areas after patients have followed a psychological treatment for this specific phobia. That is why two different sessions with fMRI will be performed, before and after an intensive treatment for the phobia. In the fMRI room, participants will wear special glasses to visualize the VR environments in which they have to navigate (using also a joystick adapted to fMRI). They will have to perform some tasks while being exposed to the phobic stimuli. The VR environment used in the fMRI sessions has three different conditions: first, a clean room without spiders or cockroaches; second, the same room, but dirty and disordered (giving the sensation of having small animals, although actually there are none); third, the same dirty room but having spiders and cockroaches. It is our hypothesis that the patients will get anxious in the situation in which it is possible that the animal appears and the patterns of brain activation will be different in this condition.
Nature and Formulation of Biogeographical Hypotheses (1975)

All biogeographical studies seem to pass through three main phases: an empirical or descriptive phase, a narrative phase, and an analytical phase, the last two being the true subject matter of explanatory historical biogeography. Narrative explanations are more or less inductively based and differ from the usual covering law models of explanation in that it is the particular circumstances in the form of an historical narrative that bear the explanatory load. Much biogeographical thinking is of this nature and the hypotheses so formulated suffer from their lack of predictive power and their basic untestability—usually they cannot be falsified and a preference between competing narrative hypotheses cannot be established on logical grounds. Examples of such hypotheses are given. The best biogeographical hypotheses are those that follow the hypothetico-deductive model and an example of how this may be done is provided. A phylogenetic systematic background is essential. Rigorously formulated hypotheses must have explanatory power, internal consistency, predictive power, and potential for falsification. Our aim should be to make our biogeographical hypotheses fit these requirements for only then will we begin to understand the history underlying modern distribution patterns.

The Vitamin D Analog, KH1060, Is Rapidly Degraded Both in Vivo and in Vitro via Several Pathways: Principal Metabolites Generated Retain Significant Biological Activity (1997)

Vitamin D analogs are valuable drugs with established and potential uses in hyperproliferative disorders.Lexacalcitol (KH1060) is over 100 times more active than 1,25-dihydroxyvitamin D 3 [1,25-(OH) 2 D 3 ], as judged by in vitro antiproliferative and cell differentiating assays.The underlying biochemical reasons for the increased biological activity of KH1060 are unknown, but are thought to include 1) metabolic considerations in addition to explanations based upon 2) enhanced stability of KH1060-liganded transcriptional complexes.In this study we explored the in vivo and in vitro metabolism of KH1060.We established by physicochemical techniques the existence of multiple side-chain hydroxylated metabolites of KH1060, including 24-, 24a-, 26-, and 26a-hydroxylated derivatives as well as side-chain truncated forms.KH1060 metabolism could be blocked by the cytochrome P450 inhibitor, ketoconazole.KH1060 was not an effective competitor of C24 oxidation of 1,25-(OH) 2 D 3 .Certain hydroxylated metabolites of KH1060 retained significant biological activity in vitamin D-dependent reporter gene systems (chloramphenicol acetyltransferase).Likewise, those metabolites accumulating in the target cell culture models in metabolism studies, particularly 24a-hydroxy-KH1060 and 26-hydroxy-KH1060, retained biological activities superior to those of 1,25-(OH) 2 D 3 in native gene expression systems in vitamin D target cells (osteopontin and P450cc24).We conclude that KH1060 is rapidly metabolized by a variety of cytochrome P450mediated enzyme systems to products, many of which retain significant biological activity in vitamin D-dependent assay systems.These results provide an explanation for the considerable biological activity advantage displayed by KH1060 compared with 1,25-(OH) 2 D 3 in various in vitro assay systems.
The impact of more visible standard drink labelling on youth alcohol consumption: Helping young people drink (ir)responsibly? (2009)

This study provides initial evidence to support the view that standard drink labelling, in isolation of other modifications to product packaging and marketing, is likely to serve to further increase heavy drinking among young people.
A computationally efficient approach to indoor/outdoor scene classification (2003)

Prior research in scene classification has shown that high-level information can be inferred from low-level image features. Classification rates of roughly 90% have been reported using low-level features to predict indoor scenes vs. outdoor scenes. However, the high classification rates are often achieved by using computationally expensive, high-dimensional feature sets, thus limiting the practical implementation of such systems. We show that a more computationally efficient approach to indoor/outdoor classification can yield classification rates comparable to the best methods reported in the literature. A low complexity, low-dimensional feature set is used in conjunction with a two-stage support vector machine classification scheme to achieve a classification rate of 90.2% on a large database of consumer photographs.

Tradeoffs in certificate revocation schemes (2003)

Cryptographic certificates are a powerful tool for security concerned applications where the participants must be authenticated in order to access some resources or commit a transaction. However, due to various reasons, the validity of such certificates can change over time, introducing the risk of an invalid certificate being used to authenticate an entity. Various methods of mitigating this risk have been devised, known broadly as "certificate revocation" schemes. In this paper, we categorize and analyze them based on our identified characteristics. We further discuss tradeoffs among them and suggest how system designers might apply the analyses.
Compressor Has No Moving Macroscopic Parts (1995)

Compressor containing no moving macroscopic parts functions by alternating piston and valve actions of successive beds of magnetic particles. Fabricated easily because no need for precisely fitting parts rotating or sliding on each other. Also no need for lubricant fluid contaminating fluid to be compressed. Compressor operates continuously, eliminating troublesome on/off cycling of other compressors, and decreasing consumption of energy. Phased cells push fluid from bottom to top, adding increments of pressure. Each cell contains magnetic powder particles loose when electromagnet coil deenergized, but tightly packed when coil energized.
Reversing Aberrant Methylation Patterns in Cancer (2010)

Changes to the epigenetic information within a cell play a significant role in cancer development and progression. These epigenetic changes are important in establishing the aberrant gene expression patterns that are a feature of cancer cell biology. We are currently experiencing a rapid advance in our understanding of how epigenetic information is written and interpreted in the cell, and the enzymes involved in these processes have been recognised as prime targets for therapeutic intervention. Reagents that target these enzymes have the potential to inhibit or reverse epigenetic changes in cancer cells. Evidence suggests that the aberrant regulation of two gene silencing pathways; involving DNA methylation and histone methylation, play an important role in cancer development. Considerable effort is being exerted in the development of inhibitors of these pathways. However, complex functional interactions exist between the DNA and histone methylation pathways, and these interactions will need to be considered in the design of inhibitory molecules. This review details current research into agents developed as inhibitors of these epigenetic pathways, focusing on the types of epigenetic modifications being targeted, interactions between these modifications and the use of these inhibitory agents in cancer treatment.
FORMER INHABITANTS OF THE CITY OF BUENOS AIRES. XVIII AND XIX CENTURIES (2012)

This paper constitutes a part of deeper research whose object of study are the former inhabitants of the city of Buenos Aires. Men and women come in spotlight when studying the basic needs of the population such as job, housing and family. With the passing of time the success or failure in the reproduction and settling (unwanted pregnancy, lack of stable income) as well as structural problems (high infant mortality rates, militarization) caused a series of adaptations in families that would lead to the acquisition of particular characteristics. Although census permit to identify population; in order to investigate the causes, changes and adaptations in the family forms in time I have used two analytical categories: amparo and desamparo. As well as a crossed genealogical model of analysis among the homes considered in the population records (1833 and 1855)
Polymerization of vinyl monomers initiated by KO<sub>2</sub>–charge transfer agent systems. II (1991)

Abstract Vinyl monomers having electron acceptor groups such as nitroethylene, acrylonitrile, and acrolein were polymerized by KO 2 –charge transfer agent initiator systems in dimethylsulfoxide (DMSO) at 25°C. The new initiator systems were found to be stable for almost 1 month under nitrogen atmosphere. The initial rate of polymerization was so fast that both conversion and molecular weight of the polymers obtained were high. Especially their molecular weight distribution was observed to be very narrow by means of gel permeation chromatography (GPC). The anion radicals generated by one electron transfer from potassium superoxide (KO 2 ) to charge transfer agents such as naphthalene, benzoquinone, azobenzene, etc., were suitable as initiator for the anionic polymerization of electron acceptor monomers. Study on block copolymerization of nitroethylene with acrylonitrile or acrolein was also attempted.

Model-less inversion-based iterative control for output tracking: Piezo actuator example (2008)

In this article, we propose a model-less inversionbased iterative control (MIIC) approach for high-speed output tracking in repetitive applications such as the lateral scanning during atomic force microscope (AFM) imaging. The MIIC algorithm extends the inversion-based iterative control (IIC) technique and the enhanced inversion-based iterative control (EIIC) technique. The main contribution of this article is the development of the MIIC algorithm to eliminate the modeling process while further enhancing the output tracking performance. We explicitly consider the disturbance and/or measurement noise effect in the convergence analysis of the MIIC algorithm. It is shown that convergence can be reached in one iteration step if the noise/disturbance effect is negligible; Or, the input error can be quantified by the disturbance/noise to signal ratio (NSR, relative to the desired trajectory). The MIIC is applied to a piezo scanner on an atomic force microscope, and experimental results are presented to demonstrate the efficacy of the MIIC technique.

An Improved SIFT Algorithm for Unmanned Aerial Vehicle Imagery (2014)

The Unmanned Aerial Vehicle (UAV) platform has the benefits of low cost and convenience compared with satellites. Recently, UAVs have shown a wide range of applications such as land use change, mineral resources management and local topographic mapping. Because of the instability of the UAV air gesture, an image matching method is necessary to match different images of an object or scene. Scale Invariant Feature Transform (SIFT) features are invariant to image scaling, rotation and translation. However, the main drawback of a SIFT algorithm is its significant memory consumption and low computational speed, particularly in the case of high-resolution imagery. In this study, in order to overcome these drawbacks, we have analysed the construction of the scale-space in the SIFT algorithm and selected new parameters to construct the SIFT scale-space to improve the memory consumption and computational speed for the processing of UAV imagery. Here, we propose a restriction on the number of octaves and levels for Gaussian image pyramids. Our experiment shows that the proposed algorithm effectively reduces memory consumption and significantly improves the operational efficiency of the feature point extraction and matching under the premise of maintaining the precision of the extracted feature points.

Probabilistic design of integrated circuits with correlated input parameters (1999)

This paper presents an application of advanced first-order second-moment (AFOSM) reliability method to probabilistic design of integrated circuits with correlated parameters. The method avoids the transformation to the space of uncorrelated parameters and provides a conservative estimate of the yield. Optimal nominal values are found such that the cost of tolerances is minimized while the desired yield is achieved. Numerical results are presented for a switched capacitor filter and verified by Monte Carlo simulation.
Multiangle method for temperature measurement of biological tissues by microwave radiometry (1991)

A new approach for deriving the temperature distribution in biological tissues of microwave radiometry is proposed. It consists in the measurement of the thermal radiation of the body, at a given frequency, as a function of the observation angle, for two mutually orthogonal polarizations. Theoretically, this method yields results comparable to those obtained with the multispectral method. In order to derive the relations between the body temperature and the emitted thermal signal, the biological body is modeled by a set of parallel planar layers, each characterized by constant permittivity and temperature. It is demonstrated that for all practical purposes the radiation pattern of the antenna may be approximated by that of an unbounded plane wave.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Recurrent vaginal candidiasis. Results of a cohort study of sexual transmission and intestinal reservoir. (1992)

Yeast cultures from the oral cavity, vagina and rectum were obtained from 125 women experiencing an acute episode of recurrent candidal vaginitis. To investigate the role of sexual transmission, oral, penile and ejaculate cultures were also prepared from all the male sexual partners. The rates of oral and rectal Candida species colonization in the women were 36% (45/125) and 44.8% (56/125), respectively. The male partners' oral cavities were positive in 23.2% (29/125) and the penile coronal sulcus and seminal fluid in 16% (20/125) and 14.4% (18/125), respectively. The susceptibility of the isolated species to the main antimycotic drugs was ascertained with the agar diffusion method. Therapy in the women and the colonized sexual partners was carried out, eliminating the microorganism from every positive site. Control cultures were obtained two weeks after the completion of therapy, and follow-up was continued for one year. The overall clinical and microbiologic cure rate in the study group was 72% (95/125). The rate of relapse was not influenced by the treatment of Candida colonization of the female intestinal tract. The recurrence rate after treatment in the couples in which the man harbored yeast (oral cavity, penile coronal sulcus, seminal fluid) was lower (15.8% vs. 44.8%, P = .0019) than that recorded in the couples without sexual partner involvement. The identification and treatment of the male sexual partner's Candida colonization seems important in the prevention of recurrent vulvovaginitis.
Migration of an inferior vena cava filter to the right ventricle and literature review. (2004)

Migration of an inferior vena cava (IVC) filter to the heart after placement is an extremely rare complication. The case of a 42-year-old man who presented with ventricular arrhythmia and tricuspid valve regurgitation, and underwent open heart surgery to extract an IVC filter from the right ventricle 12 days after infrarenal IVC filter placement, is reported.
Comparative analysis of two gain- and offset-compensated very large time constant switched-capacitor integrators (2002)

A novel gain- and offset-compensated (GOC) very large time constant (VLT) switched-capacitor (SC) integrator is presented and compared with the previously proposed Nagaraj-89 GOC VLT integrator in terms of gain error, phase error and offset voltage error. The effectiveness of the new integrator is demonstrated by designing a 60 Hz notch filter.
Isolation and crystal and molecular structure of a rare example of a mononuclear organo-cuprate (1983)

The reaction of mesitylcopper(I), CuAr, with 1,2-bis (diphenylphosphino)ethane, dppe, gives [(dppe)2Cu2Ar2], whose molecular structure, determined by a single-crystal X-ray study, consist of a linear mononuclear [CuAr2]– unit with a tetrahedral [Cu(dppe)2]+ unit as counter-ion.
Video-assisted ALIF With Cage and Anterior Plate Fixation for L5-S1 Spondylolisthesis (2006)

The results of this technique compare favorably with posterior stabilization and fusion (posterior lumbar interbody fusion and postero-lateral fusion) reported in the literature. Unlike posterior lumbar interbody fusion, however, it seems that the complication rate due to the approach is much lower, the fusion rate is similar. Grade 2 SPL is the limitation of the technique. The main advantage of the technique is to avoid posterior muscle damage and a quick recovery with no blood loss. Preservation of adjacent level disease can be assessed only after long-term follow-up.
