The Improvement of Neural Network Cascade-Correlation Algorithm and Its Application in Picking Seismic First Break

Neural Network is a kind of widely used seismic wave travel time auto-picking method. Most commercial software such as Promax often uses Back Propagation (BP) neural network. Here we introduce a cascade-correlation algorithm for constructing neural network. The algorithm’s convergence is faster than BP algorithm and can determine its own network architecture according to training samples, in addition, it can be able to expand network topology to learn new samples. The cascaded-correlation algorithm is improved. Different from the standard cascade-correlation algorithm, improved algorithm starts at an appropriate BP network architecture (exits hidden units), but the standard one’s initial network only includes input layer and output layer. In addition, in order to prevent weight-illgrowth, adding regularization term to the objective function when training candidate hidden units can decay weights. The simulation experiment demonstrates that improved cascade-correlation algorithm is faster convergence speed and stronger generalization ability. Analytically study five attributes, including instantaneous intensity ratio, amplitude, frequency, curve length ratio, adjacent seismic channel correlation. Intersection figure shows that these five attributes have distinctiveness of first break and stability. The neural network first break picking method of this paper has achieved good effect in testing actual seismic data. Key words : Neural network; Cascade-correlation algorithm; Picking seismic first break
Particle scattering and vacuum instability by exponential steps

Particle scattering and vacuum instability in a constant inhomogeneous electric field of particular peak configuration that consists of two (exponentially increasing and exponentially decreasing) independent parts are studied. It presents a new kind of external field where exact solutions of the Dirac and Klein-Gordon equations can be found. We obtain and analyze in- and out-solutions of the Dirac and Klein-Gordon equations in this configuration. By their help we calculate probabilities of particle scattering and characteristics of the vacuum instability. In particular, we consider in details three configurations: a smooth peak, a sharp peak, and a strongly asymmetric peak configuration. We find asymptotic expressions for total mean numbers of created particles and for vacuum-to-vacuum transition probability. We discuss a new regularization of the Klein step by the sharp peak and compare this regularization with another one given by the Sauter potential.
Somatic embryogenesis in Mucuna pruriens Harini S

This study reports the induction of somatic embryos in Mucuna pruriens. Different explants cultured on MS medium supplemented with 11.31 μM 2,4-D produced golden yellow embryogenic callus that induced synchronized embryo development on MS basal liquid medium. Organization of pre-embryonic mass was noticed 15 d after sub culturing the callus, which progressively developed to globular, heart, torpedo and cotyledonary shaped embryos. Attempts to germinate them did not succeed as the cotyledonary embryos turned characteristic red and subsequently brown before finally turning black and unresponsive. The reaction was consistent across different media constituents, hormonal concentrations and pH ranges. Supplementation of anti-oxidants was also ineffective. Polyacrylamide gel electrophoretic analysis of the brown and non-brown embryos revealed quantitative differences in protein contents between the two. More detailed study is necessary to establish the precise cause for embryo browning and ways of its regulation.
Hopf Cyclic Cohomology in Non-symmetric Monoidal Categories

First, referring to our previous work, 'Hopf cyclic cohomology in braided monoidal categories', we reduce the restriction of the ambient category C being symmetric. We let C to be non-symmetric but assume only the restriction, ψ 2 = id, on the braid map correspond to the Hopf algebra H, which is the main player in the theory. We define a family of examples of such desired braided Hopf algebras, H, living in the category of anyonic vector spaces. Next, on one hand, we will prove that these anyonic Hopf algebras are the enveloping (Hopf) algebras of particular quantum Lie algebras, which we will construct. On the other hand, we will show that, analogous to the non-super and the super case, the well known relationship between the periodic Hopf cyclic cohomology of an enveloping (super) algebra and the (super) Lie algebra homology also holds for these particular quantum Lie algebras.
Pattern of Wing Moult and Its Relationship to Breeding in the Eurasian Stone-Curlew Burhinus oedicnemus

The timing, duration and pattern of the poorly documented wing moult in the Eurasian Stone-curlew Burhinus oedicnemus were described and related to the breeding cycle. Between 1998 and 2007, 141 birds were trapped in the Taro River Regional Park (Parma, Italy) both while incubating and during the post-breeding season. The timing of primary moult was estimated according to the method of Underhill & Zucchini (1988) and Underhill et al. (1990). Primary moult was very slow and overlapped most of the breeding season, beginning in early May and ending in October. Secondary moult was much more irregular and was not completed within a single moult cycle. Innermost and outermost secondaries were more likely to be shed than those at the centre of this tract. Juvenile secondaries were not shed during the first winter. The study provides the first detailed analysis of wing moult in the Eurasian Stone-curlew and suggests some useful ageing criteria based on the pattern of secondary moult. The extensive overlap between breeding and moulting is relatively uncommon compared to other waders. This could be interpreted as a way to maximize breeding success through renesting potential (up to 4 attempts), i.e. by spreading the cost of moult over a prolonged time period. A between-species comparison using independent contrasts was consistent with this hypothesis: species with a prolonged breeding season also showed considerable overlap in the timing of primary moult and breeding activities.
Evolution or Revolution of Organizational Information Technology – Modeling

This paper suggests a new normative model that attempts to analyze why improvement of versions of existing decision support systems do not necessarily increase the effectiveness and the productivity of decision making processes. Moreover, the paper suggests some constructive ideas, formulated through a normative analytic model, how to select a strategy for the design and switching to a new version of a decision support system, without having to immediately run through a mega conversion and training process while temporarily losing productivity. The analysis employs the information structure model prevailing in Information Economics. The study analytically defines and examines a systematic informativeness ratio between two information structures. The analysis leads to a better understanding of the performances of decision support information systems during their life-cycle. Moreover, this approach explains normatively the phenomenon of “leaks of productivity”, namely, the decrease in productivity of information systems, after they have been upgraded or replaced with new ones. Such an explanation may partially illuminate findings regarding the phenomenon known as the Productivity Paradox. It can be assumed that the usage of the methodology that is presented in this paper to improve or replace information structure with systematically more informative versions of information structures over time may facilitate the achievement of the following major targets: increase the expected payoffs over time, reduce the risk of failure of new versions of information systems, and reduce the need to cope with complicated and expensive training processes.
A new generator of chaotic bit sequences with mixed-mode inputs

This paper presents a new generator of chaotic bit sequences with mixed-mode (continuous and discrete) inputs. The generator has an improved level of chaotic properties in comparison with the existing single source (input) digital chaotic bit generators. The 0-1 test is used to show the improved chaotic behavior of our generator having a chaotic continuous input (Chua, R\"{o}ssler or Lorenz system) intermingled with a discrete input (logistic, Tinkerbell or Henon map) with various parameters. The obtained sequences of chaotic bits show some features of random processes with increased entropy levels, even in the cases of small numbers of bit representations. The properties of the new generator and its binary sequences compare well with those obtained from a truly random binary reference quantum generator, as evidenced by the results of the $ent$ tests.
Heat Pipe Solar Receiver Development Activities at Sandia National Laboratories

Over the past decade, Sandia National Laboratories has been involved in the development of receivers to transfer energy from the focus of a parabolic dish concentrator to the heater tubes of a Stirling engine. Through the isothermal evaporation and condensation of sodium. a heat-pipe receiver can efficiently transfer energy to an engine's working fluid and compensate for irregularities in the flux distribution that is delivered by the concentrator. The operation of the heat pipe is completely passive because the liquid sodium is distributed over the solar-heated surface by capillary pumping provided by a wick structure. Tests have shown that using a heat pipe can boost the system performance by twenty percent when compared to directly illuminating the engine heater tubes. Designing heat pipe solar receivers has presented several challenges. The relatively large area ({approximately}0.2 m{sup 2}) of the receiver surface makes it difficult to design a wick that can continuously provide liquid sodium to all regions of the heated surface. Selecting a wick structure with smaller pores will improve capillary pumping capabilities of the wick, but the small pores will restrict the flow of liquid and generate high pressure drops. Selecting a wick that is comprised of very tine filamentsmore » can increase the permeability of the wick and thereby reduce flow losses, however, the fine wick structure is more susceptible to corrosion and mechanical damage. This paper provides a comprehensive review of the issues encountered in the design of heat pipe solar receivers and solutions to problems that have arisen. Topics include: flow characterization in the receiver, the design of wick systems. the minimization of corrosion and dissolution of metals in sodium systems. and the prevention of mechanical failure in high porosity wick structures. « less

A new model for planning the distributed facilities locations under emergency conditions and uncertainty space in relief logistics

Article history: Received July 2, 2016 Received in revised format September 10, 2016 Accepted October 21 2016 Available online October 21 2016 The life of many people across the world can face various dangers with incurrence of incidents and unpredictable diseases. Incidents often require quick relief as they directly affect human lives. The process of planning, management and monitoring the flow of relief sources to injured and sick individuals is called relief logistics. When best relief services are provided through available sources, relief logistics appear. In this article, a multi-objective model for relief resources distribution facilities under an uncertain condition is investigated in two ways of demand satisfaction by considering the relief resources accessibility and demand satisfaction in a fuzzy logic. In the presented model, the concepts of cost, chance of demand satisfaction, elevation of response capability of system, discount levels for relief commodities, late satisfaction of demand, hub for accumulation of late and returned orders and special route for time significance in distribution of relief commodities are considered. For the first problem, the chance of relief resources accessibility and for the second problem, demands were investigated using fuzzy logic. Considering the conducted analysis, the demand amount is taken more in the second problem than the first one, which has led to an increase in the cost of the second problem. On one hand, the chance of demand satisfaction with no late orders is higher than the second problem. Satisfaction of demand occurs more in the second problem as well. Thus, these problems should be utilized in a way that suits the space of this problem. To solve the problem and to do the sensitivity analysis, we present a NSGA-II algorithm to deal with multi-objectiveness of the problem. A ε-Constraint method is also proposed to evaluate the performance of the proposed algorithm. Growing Science Ltd. All rights reserved. 7 © 201
An Acoustic Study of the Word-final Lateral Approximant in Korea

The phonological representation of the Korean lateral has been widely discussed while less attention has been paid to the phonetic realizations of the sound. In the present study, we examine the static and dynamic properties of the Korean lateral from a production study and we measure the duration, the three formants and the time-normalized trajectories. Based on the results of a production study, it was found that (i) the duration of the lateral approximant in Korean is constant irrespective of the preceding vowel contexts, that (ii) the three formants of the lateral are severely influenced by the preceding contexts, and that (iii) the initial part of the lateral articulation share similar acoustic properties with the preceding vowels, but as the articulation continues, it becomes unaffected by the vowels.
Involvement of mast cells , CD 68 + and VEGF + expressions in response to Himatanthus drasticus commercial latex in mice wound healing model

This study aimed to evaluate Himatanthus drasticus latex in a mice wound healing experimental model. Animals were divided into four groups (n=7) according to the treatments: GI saline 0.9% (control), GII mineral oil (vehicle), GIII H. drasticus commercial latex (HdCL) and GIV H. drasticus mixed isolated fraction (MIF, 1 mg/mL). The treatments were applied topically once daily, 50 μL for 14 consecutive days. Macroscopic lesions were evaluated, considering parameters such as swelling, redness, granulation tissue and reepithelialization. VEGF+, CD68+ expressions and mast cells (Toluidin blue stain) were evaluated. HdCL induced higher contraction and exuberant granulation tissue (P > 0.05). HdCL showed a mild inflammatory process while MIF induced intense infiltrate inflammatory predominantly by lymphocytes, vascular congestion, bleeding and did not presented full reepithelialization. Reorganization of collagen fibers (red picrosirius stain) was observed. CD68+ expression and mast cells were presented as moderate, intense and mild in GI, GIII and GIV, respectively. Neovascularization occurred in all groups, while VEGF+ expression was intense in MIF in relation to HdCL. We concluded that HdCL presents wound healing potential, through modulation of mast cells, CD68+ and VEGF+ expressions that can be associated to triterpenes presence according MIF isolated from HdCL.
Spectroscopy of the variable K-dwarf UNSW-V-760: is it a pre-main-sequence pulsator?

The star UNSW-V-760 is a known variable, showing both flares and two non-sinusoidal periodicities. Availability of high signal-to-noise spectra reported in this paper has enabled a revision of the spectral type of this star to K3 IV-Vk. The star is a very rapid rotator (v sini ∼ 140 km s −1 ), and the abundance of lithium appears to be enhanced. 48 radial velocity measurements were obtained over the course of three successive nights. These may show the same two frequencies detected photometrically, but there is some uncertainty in the interpretation. Application of pulsation theory suggests that photometric frequencies could be explained
Optimization of the Speaker Recognition in Noisy Environments Using a Stochastic Gradient Descent

Noise-robust speech recognition system is still one of the ongoing, challenging problems, since these systems usually work in the noisy environments, such as offices, vehicles, airplanes, and others. Even though deep learning algorithms provide higher performances, there is still a large recognition drop in the task of speaker recognition in noisy environments. The proposed system is tested on VIDTIMIT dataset in the presence of Additive White Gaussian Noise changing the Signal-to-Noise Ratio levels. The experimental results show how the optimization of Stochastic Gradient Descent algorithm parameters such as learning rate and dropout rate, can improve the performance of speech recognition in both noisy and less noisy environments.
SOME STATISTICAL EVALUATIONS OF NUMERICALLY OBTAINED ATMOSPHERIC COMPOSITION FIELDS IN BULGARIA

Some extensive numerical simulations of the atmospheric composition fields in Bulgaria have been recently performed. The obtained ensemble of numerical simulation results is large enough to allow statistical treatment - calculating not only the mean concentrations and different source categories contribution mean fields, but also standard deviations, skewness, probability density functions, etc. with their dominant temporal modes (seasonal and/or diurnal variations).
The role of over expression of P5CS gene on proline, catalase, ascorbate peroxidase activity and lipid peroxidation of transgenic tobacco (Nicotiana tabacum L.) plant under in vitro drought stress

In this study proline content and activity of catalase (CAT), and ascorbate peroxidase (APX) and level of lipid peroxidation in terms of malondialdehyde (MDA) content were measured in transgenic tobacco (Nicotiana tabacum cv. Wisconsin), over expressing a Δ-1-pyrroline-5-carboxylate synthase (P5CS) gene, and non transgenic plants as control. Drought stress was applied using polyethylene glycol (PEG) 6000 at concentrations of 217, 264, 320, 637, 1292 mmol/kg equal to (0, 5, 10, 20, 30% respectively). Proline content, especially in transgenic plants, was increased in leaves and roots signiﬁcantly. CAT and APX activities increased under drought stress and the highest activity was observed in 10 and 20% of the PEG treatment. MDA content was increased by increasing of PEG and the highest MDA content was revealed in transgenic and non transgenic plants at 20% and 30%, respectively. Our results suggest that P5CS is an inducible gene and over production of proline and induction of CAT and APX activities are involved in drought tolerance mechanism.
CARDIOVASCULAR ENGINEERING: MODELIZATION OF VENTRICULAR-ARTERIAL INTERACTION IN SYSTEMIC AND PULMONARY CIRCULATION

The heart pumps pressure and flow signals with relevant amount of frequency components cushioned along the arterial system. A pressure transfer function approach was designed to evaluate the Ventricular-Arterial Interaction. Two transfer functions were calculated relating ventricular to arterial pressure. A frequency response analysis followed the time-domain adaptation. Additionally, a viscoelastic model was proposed to characterize the arterial wall mechanical behavior, using the elastic (E) and viscous (η) moduli. Six merino sheep were instrumented and anesthetized. Pressure measurements were registered in both ventricles, in aorta and in the pulmonary artery. Diameters (sonomicrometry) were measured in both arteries. The frequency transfer function asymptotic negative slope, describing the attenuation within the dynamic range, resulted 5 times greater in aorta (p<0.05), what presents the systemic as a more selective circuit than the pulmonary. E and η resulted higher (p<0.05) in aorta than in the pulmonary artery whereas E/η was similar. The viscoelastic results might indicate a similar segmental (unit-cell) response in both arteries. The enhanced cushioning ability of the left circuit with respect to the right, might be understood as a more selective vascular filtering system. This filtering performance might be related to the functional length of unit-cell responses along the systemic circulation.
FERMENTATION QUALITY OF KING GRASS SILAGE TREATED WITH LIQUID OR DRIED INOCULANT OF LACTIC ACID BACTERIA

The aim of this study was to evaluate the nutritive value and fermentation characteristic of king grass silage treated with addition of liquid or dried lactic acid bacteria (LAB) inoculant. Experiment was arranged to a completely randomized design with four treatments and three replications. Four treatments as follows (A) king grass without LAB inoculant as the control; (B) king grass + 30 ml of liquid of epiphytic LAB inoculant/kg of fresh forage; (C) king grass + 30 g of freeze-dried powder of LAB inoculant/kg of fresh forage; (D) king grass + 30 g of centrifuged powder of LAB inoculant/kg of fresh forage. The liquid LAB inoculant was sprayed on the top of grass and then mannualy mixed by hand. The intial LAB concentration in all inoculants were 1.0 × 106 cfu/g. About 500 g of silage materials were ensiled into plastic silos and stored at room temperatures (approximately 28oC) for 30 days. Results showed that pH value, concentrations of lactic acid, N-amonia (NH3-N), butyric acid and total volatile fatty acids (VFA) as well as Fleigh Point were affected by treatment of LAB inoculant. Silage treated with liquid or dried of LAB inoculant had lower (P<0.01) pH value compared to the control silage. Concentrations of NH3-N and butyric acid significantly decreased (P<0.01) in silage treated with LAB inoculants. Silage treated with centrifuged powder of LAB inoculant had the highest (P<0.05) Fleigh Point than other silage. In vitro neutral detergent fiber (NDF) digestibility was significantly higher (P<0.05) in silage treated with LAB inoculant compared to the control silage.
