A two-dimensional PSV hybrid method and its application to modeling localized structures near the core-mantle boundary

A P-SV hybrid method is developed for calculating synthetic seismograms involving two-dimensional localized heterogeneous structures. The finite difference technique is applied in the heterogeneous region and generalized ray theory solutions from a seismic source are used in the finite difference initiation process. The seismic motions, after interacting with the heterogeneous structures, are propagated back to the Earth's surface analytically with the aid of the Kirchhoff method. Anomalous long-period SKS-SPdKS observations, sampling a region near the core-mantle boundary beneath the southwest Pacific, are modeled with the hybrid method. Localized structures just above the core-mantle boundary, with lateral dimensions of 250 to 400 km, can explain even the most anomalous data observed to date if S velocity drops up to 30% are allowed for a P velocity drop of 10%. Structural shapes and seismic properties of those anomalies are constrained from the data since synthetic waveforms are sensitive to the location and lateral dimension of seismic anomalies near the core-mantle boundary. Some important issues such as the density change and roughness of the structures and the sharpness of the' transition from the structures to the surrounding mantle, however, remain unresolved due to the nature of the data.
Theoretische Ansätze zur Erklärung von Ähnlichkeit und Unähnlichkeit in Partnerschaften

Im Hinblick auf die Ahnlichkeit (bzw. Unahnlichkeit) von Partnern existieren die Redewendungen Gleich und gleich gesellt sich gern sowie Gegensatze ziehen sich an. In dieser Arbeit wird zunachst unter Bezugnahme auf empirische Untersuchungen verdeutlicht, dass die erste der beiden genannten Redewendungen eher zutrifft als die zweite (Abschnitt 2). Anschliesend werden zwei verschiedene theoretische Erklarungsansatze skizziert: der okonomische Ansatz, bei dem die Partnerwahl unter dem Gesichtspunkt der Nutzenmaximierung betrachtet wird (Abschnitt 3), und der rollentheoretische Ansatz, demzufolge die Ubereinstimmung der Rollenvorstellungen von Frau und Mann masgebend fur das Funktionieren einer Partnerschaft ist (Abschnitt 4).
Hormonal abnormalities in obesity.

We have found a number of interesting hormonal abnormalities in obese men and women: 1) Obese women have normal levels of estrone, total estradiol, and total testosterone, but as a consequence of their subnormal levels of SHBG, their levels of free estradiol and free testosterone are significantly elevated. 2) Massive weight loss in obese women (to still elevated weight) results in normalization of the previously elevated free estradiol and free testosterone. 3) Obese women have normal plasma DHEA levels, but a significant, age-invariant decrease of the plasma DHEA/T ratio, which could be due to increased tissue activity of 3 beta-hydroxysteroid dehydrogenase. 4) Massive weight loss produces an age-dependent effect on DHEA levels in obese women: the levels increase to supranormal values in women around age 20, with diminishing increases at higher premenopausal ages and no increase at all at perimenopausal age. 5) Obese men have elevated levels of estrone and both free and total estradiol, and subnormal levels of free and total testosterone and of FSH; all these abnormalities are proportional to the degree of obesity. They also have relatively subnormal LH levels, i.e. normal in the face of hypotestosteronemia. The combination of these findings represents a state of mild hypogonadotropic hypogonadism (HHG), which we believe to be induced by the hyperestrogenemia. 6) Normalization of the estrogen levels of obese men, by suppression of adrenocortical secretion of aromatase substrates or by inhibition of aromatase, tends to normalize the HHG. 7) Massive weight loss in obese men normalizes their HHG without any decrease in plasma estrogen levels.

Comparison of Ofloxacin & Ornidazole with Probiotic versus Doxycycline & Metronidazole for the Outpatient Treatment of Pelvic Inflammatory Disease

Introduction Pelvic inflammatory disease (PID) is a polymicrobial infection of upper genital tract (usually fallopian tubes). It is a serious infectious disease of sexually active women with sequelae such as infertility and ectopic pregnancy (1, 2). It is most commonly caused by Neisseria gonorrhoea, Chlamydia trachomatis and other aerobic and anaerobic pathogens (3, 4). Most patients of PID are treated as outpatients with hospitalization reserved for sick patients or those with complications like diffuse peritonitis or pelvic abscess (5). In view of multiplicity of pathogens combined with the difficulty in obtaining cultures from upper genital tract sites, centre for disease Abstract
A novel PFC circuit using ladder type filter employing only passive devices

For various rectifier circuits such as those for consumer electronics and appliances, rectifier circuits of the capacitor input type are generally used. It is known that such rectifier generates various harmonics in the power system. To improve those harmonic problems, various PFC circuits have been proposed so far. Among these, Takahashi have proposed a PFC scheme using a LC filter without switching devices. This method makes a PFC effect by widening conduction period using the operations of capacitors and inductor. On the basis of this scheme, we propose another PFC circuit. This method attempts to improve the input current, towards satisfactory waveform by using a novel ladder type filter.

Identifying biomarkers of diabetes with gene coexpression networks

Diabetes is one of the most prevalent diseases worldwide, and hundreds of millions of patients are suffering from diabetes and its serious complications. Early detection and early treatment are urgent needed for clinical diagnosis of diabetics. In this work, we establish a gene coexpression network framework to identify biomarkers of transcripts with highly different gene coexpression patterns in disease and control samples. We category the differentially expressed genes into four groups by their pair-wise gene coexpression dynamics, i.e., the gene pairs with (and/or without) high correlation in disease samples, while without (and/or with) high correlation in control samples. And we then identify the key genes significantly associated with the pathogenesis of diabetes mellitus. We evaluate the classification abilities of these gene groups by a support vector machine based method. The genes with good classification accuracy are further investigated in functional enrichment analysis, which are served as identified biomarkers.
griffith . edu . au Face Recognition based on Gradient Gabor feature

In this paper, a novel Gradient Gabor (GGabor) filter is proposed to extract multi-scale and multi-orientation features to represent and classify faces. Gradient Gabor combines the derivative of Gaussian functions and the harmonic functions to capture the features in both spatial and frequency domains to deliver orientation and scale information. The spatial positions are combined into Gaussian derivatives which allows it to provide more stable information. An Efficient Kernel Fisher analysis method is proposed to find multiple subspaces based on both GGabor magnitude and phase features, which is a local kernel mapping method to capture the structure information in faces. Experiments on two face databases, FRGC Version 1 and FRGC Version 2, are conducted to compare the performances of the Gabor and GGabor features, which show that GGabor can also be a powerful tool to model faces, and the Efficient Kernel Fisher classifier can improve the efficiency of the original kernel fisher method.
A poliovirus minireplicon containing an inactive 2A proteinase is expressed in vaccinia virus-infected cells

It has been difficult to evaluate the role of individual viral proteins in poliovirus replication because a suitable complementation system has not yet been developed. To approach this problem, we constructed a chimeric human immunodeficiency virus type 2 (HIV-2)-gag-poliovirus minireplicon in which regions of the gag gene of HIV-2 were inserted in the poliovirus genome between nucleotides 1174 and 2470. Transfection of this chimeric RNA into HeLa cells results in the replication of the minireplicon and expression of an HIV-2-gag-P1 fusion protein which can be immunoprecipitated with antibodies to HIV-2-gag. Expression of the HIV-2-gag-P1 fusion protein was dependent on replication of the chimeric RNA genome. Although the chimeric HIV-2-gag-poliovirus RNA genome replicated in poliovirus-infected cells, transfection of the chimeric HIV-2-gag-poliovirus genome into vaccinia virus-infected cells resulted in increased replication as measured by analysis of chimeric RNA. The increase in replication correlated with an increase in the expression of the HIV-2-gag-P1 fusion protein in vaccinia virus-infected cells. To characterize this system, we constructed a mutation in the 2A gene to change a cysteine at amino acid 109 to a serine. Expression of the HIV-2-gag-P1 fusion protein was not detected when the HIV-2-gag-poliovirus genome containing the 2A mutation was transfected into HeLa cells, demonstrating the mutation was lethal for replication. When the chimeric genome was transfected into poliovirus-infected cells, no RNA replication or expression of the HIV-2-gag-P1 fusion protein was observed. In contrast, transfection of this genome into vaccinia virus-infected cells resulted in replication of the chimeric RNA and expression of two proteins with larger molecular masses than the HIV-2-gag-P1 proteins, possibly representing HIV-2-gag-P1-2A and HIV-2-gag-P1-2ABC fusion proteins. The transfection of the chimeric HIV-2-gag-poliovirus genome containing the 2A mutation into poliovirus-vaccinia virus coinfected cells resulted in the expression and partial processing of the two larger HIV-2-gag-P1 fusion proteins to give the correct molecular mass for the HIV-2-gag-P1 fusion protein. The 2A mutation was reconstructed back into the full-length infectious cDNA of poliovirus. Transfection of this cDNA into vaccinia virus-infected cells followed by immunoprecipitation with anticapsid antibodies demonstrated the presence of two proteins with molecular masses larger than P1, possibly P1-2A and P1-2ABC fusion proteins.

Senti‐CS: Building a lexical resource for sentiment analysis using subjective feature selection and normalized Chi‐Square‐based feature weight generation

Sentiment analysis involves the detection of sentiment content of text using natural language processing. Natural language processing is a very challenging task due to syntactic ambiguities, named entity recognition, use of slangs, jargons, sarcasm, abbreviations and contextual sensitivity. Sentiment analysis can be performed using supervised as well as unsupervised approaches. As the amount of data grows, unsupervised approaches become vital as they cut down on the learning time and the requirements for availability of a labelled dataset. Sentiment lexicons provide an easy application of unsupervised algorithms for text classification. SentiWordNet is a lexical resource widely employed by many researchers for sentiment analysis and polarity classification. However, the reported performance levels need improvement. The proposed research is focused on raising the performance of SentiWordNet3.0 by using it as a labelled corpus to build another sentiment lexicon, named Senti‐CS. The part of speech information, usage based ranks and sentiment scores are used to calculate Chi‐Square‐based feature weight for each unique subjective term/part‐of‐speech pair extracted from SentiWordNet3.0. This weight is then normalized in a range of −1 to +1 using min–max normalization. Senti‐CS based sentiment analysis framework is presented and applied on a large dataset of 50000 movie reviews. These results are then compared with baseline SentiWordNet, Mutual Information and Information Gain techniques. State of the art comparison is performed for the Cornell movie review dataset. The analyses of results indicate that the proposed approach outperforms state‐of‐the‐art classifiers.
H∞ sampled data control of systems with time-delays

Sampled-data Hinfin control of linear systems with state, control and measurement constant delays is considered. The sampling of the controlled input and of the measured output is not assumed to be uniform. The system is modelled as a continuous-time one, where the controlled input and the measurement output have piecewise-continuous delays. The input-output approach to stability and L2-gain analysis is applied to the resulting system. The discretized Lyapunov functional method is extended to the case of multiple delays, where the Lyapunov functional is complete in one of the delays (in the state) and is simple in the other delays (in the input and in the output), which are unknown, time-varying with known upper-bounds. Solutions to the state-feedback and the output- feedback Hinfin control problems are derived in terms of linear matrix inequalities (LMIs).
The Type IV phosphodiesterase inhibitor rolipram interferes with drug‐induced conditioned place preference but not immediate early gene induction in mice

Behavioural effects of psychostimulant and opiate drugs are mediated in part by cAMP pathways operating in the nucleus accumbens. Degradation of cAMP occurs through the action of phosphodiesterases, such as the Type IV phosphodiesterases (PDE4s) that are found throughout the brain. To examine the potential role of PDE4 in reward‐mediated behaviour, we measured the effects of rolipram, a PDE4 selective inhibitor, on cocaine (18 mg/kg i.p.) and morphine (5 mg/kg s.c.) conditioned place preference in Swiss Webster mice. Rolipram (0, 0.2 or 1.0 mg/kg i.p.) given 30 min prior to drug administration dose‐dependently reduced conditioning due to both cocaine and morphine. However, rolipram did not affect place preference induced by food, nor did it prevent the expression of a previously established place preference conditioned by cocaine or morphine. In a second experiment, rolipram administered 30 min prior to a single cocaine injection (50 mg/kg i.p.), did not alter cocaine‐induced c‐Fos expression in the caudate putamen or nucleus accumbens core. However, rolipram, but not cocaine, induced c‐Fos in the nucleus accumbens shell. These results indicate that elevation of cAMP in neurons that express PDE4s may attenuate the rewarding properties of cocaine and morphine, but does not alter the cocaine signalling cascade that induces c‐Fos expression. Thus, PDE4‐mediated regulation of cAMP levels could underlie the establishment of reward valence to abused drugs.
A semi-structured clinical interview for the assessment of diagnosis and mental state in the elderly: the Geriatric Mental State Schedule: I. Development and reliability

Synopsis A standardized, semi-structured interview for examining and recording the mental state in elderly subjects is described. It allows the classification of patients by symptom profile and can demonstrate changes in that profile over time. It is believed that good reliability is demonstrated between psychiatric raters both for psychiatric diagnosis made on the basis of the schedule findings and for individual items. The Geriatric Mental State Schedule (GMS) consists mainly of items from the eighth edition of the PSE (Wing et al. 1967), together with additional items from the PSS (Spitzer et al. 1964), and extra sections dealing with disorientation and other cognitive abnormalities. Modifications have been introduced to facilitate interviewing elderly subjects.
An alternative bioassay employing neonate larvae for determining the toxicity of suspended particles to mosquitoes.

An alternative bioassay using neonate larvae of Aedes aegypti is described for determining the toxicity of suspended particles, particularly insecticidal bacteria, to mosquitoes. This new assay is comparable in precision to the 4th instar bioassay recommended by the World Health Organization, but is quicker and requires much less space. Values obtained using neonate larvae as the test insect showed less variation within and between replicates in regard to LC50 and slope of the regression line, and in general required fewer replicates to fulfill the requirements for a statistically valid bioassay than the W.H. O. assay. The precision of the neonate larval bioassay in combination with its requirements for less time and space may make it especially useful for screening large numbers of samples.
Effect of the psychoactive metabolite of marijuana, delta 9-tetrahydrocannabinol (THC), on the synthesis of tumor necrosis factor by human large granular lymphocytes.

The natural killer cell (NK)/3polymorphonuclear neutrophil axis has recently been identified to be important in early defense against the opportunistic fungi, Candida albicans. Repression of this system is therefore likely to contribute to susceptibility to opportunistic infections. delta 9-Tetrahydrocannabinol (THC), an active constituent of marijuana, has been reported to be immunosuppressive at concentrations that exceed attainable plasma levels. In this report, we examine the possibility that human large granular lymphocytes (LGL) can be immunosuppressed by exposure to THC at physiologically relevant concentrations and probed two functions associated with LGL, i.e., cytokine production and tumoricidal activity. We find that these low levels of THC inhibit tumor necrosis factor-alpha (TNF) induction from LGL by C. albicans and are dependent upon THC dose (0.005-5.0 micrograms/ml) and length of exposure (0.05-3.0 hr). Northern blot analysis indicates that the downregulation of TNF production from LGL by THC resides at the mRNA level. Moreover, exposure of LGL to physiological THC concentrations (0.01-2.0 micrograms/ml) diminishes their cytolytic activity against K562 tumor cells.
MEMS-based multiple fourier-horn silicon ultrasonic atomizer for inhalation drug delivery

Silicon-based centimeter-sized 1.0 - 2.0 MHz ultrasonic nozzles that employ multiple-Fourier horns and external liquid feeding have been realized to produce micrometer-sized (2.2 to 4.6μm) monodisperse droplets at high throughput (600μl/min) and low electrical drive power (<;1 W). A preliminary battery-operated atomizer module has been constructed for inhalation drug delivery.
Cx36 expression in the AII‐mediated rod pathway is activity dependent in the developing rabbit retina

Gap junctions are composed of connexin 36 (Cx36) and play a critical role in the rod photoreceptor signaling pathways of the vertebrate retina. Despite the fact that their connection and modulation in various rod pathways have been extensively studied in adult animals, little is known about the contribution and regulation of gap junctions to the development of the AII amacrine cell (AC)‐mediated rod pathway. Using immunohistochemistry and microinjection, this study demonstrates a steady increase in relative Cx36 protein expression in both plexiform layers of the rabbit retina at around the time of eye opening. However, immediately after eye opening, most Cx36 immunoreactive AII ACs show no gap junction coupling pattern to neighboring cells and it is not until the third postnatal week that AII cells begin to exhibit an adult‐like tracer‐coupling pattern. Moreover, studies using dark‐rearing and AMPA receptor blockade during postnatal development both revealed that relative levels of Cx36 immunoreactivity in AII ACs were increased when neural activity was inhibited. Our findings suggest that Cx36 expression in the AII‐mediated rod pathway is activity dependent in the developing rabbit retina. © 2015 Wiley Periodicals, Inc. Develop Neurobiol 76: 473–486, 2016
Organoleptic assessment of halitosis for dental professionals—general recommendations

An organoleptic assessment of an odor is defined as a method that can measure the strength of target odors and expresses the value in terms of a point or number with reference to a pre-defined organoleptic scale. Organoleptic assessments are performed using different scales and are used widely in industry (e.g. for measuring the effectiveness of anti-odor agents), in research (to discover relationships between bad breath and microbiology of the tongue, or the generation of particular volatile compounds), but it is also a prerequisite for the diagnosis of halitosis in individual patients required before directing appropriate treatment. An organoleptic assessment of halitosis patients may be carried out in specialized institutions but—based on the fact that in most cases the odor originates from oral structures—also by dental professionals including general dental practitioners (GDPs). Thus, this paper describes the scientific background for recommendations on how a GDP or dental hygienist or general practitioner with cases of bad breath should use organoleptic methods as a valid approach to assess malodor in patients, with a view to diagnosis and treatment, and subsequent treatment monitoring.
Energy Storage System With Supercapacitor for an Innovative Subway

In this paper, a new energy storage system (ESS) is developed for an innovative subway without supply rail between two stations. The ESS is composed of a supercapacitor bank and a braking resistor. An inversion-based control of the ESS is deduced from the Energetic Macroscopic Representation of the entire system. This control scheme requires a distribution criterion in order to allow the energy to be shared between the supercapacitors and the braking resistor. Different cases are evaluated via a Hardware-In-the-Loop simulation using a reduced-power ESS. The suggested control enables the energy recovery to be maximal and secure the supercapacitor in real time for different track configurations.
