On the fractional stochastic integration for random non-smooth integrands

Abstract The paper suggests a way of stochastic integration of random integrands with respect to fractional Brownian motion with the Hurst parameter H > 1∕2. The integral is defined initially on the processes that are” piecewise” predictable on a short horizon. Then the integral is extended on a wide class of square integrable adapted random processes. This class is described via a mild restriction on the growth rate of the conditional mean square error for the forecast on an arbitrarily short horizon given current observations. On the other hand, a pathwise regularity, such as Hölder condition, etc., is not required for the integrand. The suggested integration can be interpreted as foresighted integration for integrands featuring certain restrictions on the forecasting error. This integration is based on Itô’s integration and does not involve Malliavin calculus or Wick products. In addition, it is shown that these stochastic integrals depend right continuously on H at H = 1/2.
SENSITIVITY OF THE BEHAVIOR OF BACKFLOW CEX IONS TO ION ENGINE PLUME CHARACTERISTICS

A plume from the MUSES-C ion engine was numerically analyzed using the DSMC-PIC method. Computed results were compared with experimental ones, and the optimal parameters were sought so as to fit to the experiments. Thus determined optimal parameters are the beam expansion angle of 15◦ and the Gaussian density profile coefficient of 0.6. In the second stage, the sensitivities of the behavior of CEX ion in the backflow region to charge-exchange cross section, electron temperature, Gaussian density profile coefficient and beam expansion angle were investigated. Finally, the effect of the back wall on the behavior of CEX ion flux was examined.
Multi-agent query reformulation: Challenges and the role of diversity

We investigate methods to efficiently learn diverse strategies in reinforcement learning for a generative structured prediction problem: query reformulation. In the proposed framework an agent consists of multiple specialized sub-agents and a meta-agent that learns to aggregate the answers from sub-agents to produce a final answer. Sub-agents are trained on disjoint partitions of the training data, while the meta-agent is trained on the full training set. Our method makes learning faster, because it is highly parallelizable, and has better generalization performance than strong baselines, such as an ensemble of agents trained on the full data. We evaluate on the tasks of document retrieval and question answering. The improved performance seems due to the increased diversity of reformulation strategies. This suggests that multi-agent, hierarchical approaches might play an important role in structured prediction tasks of this kind. However, we also find that it is not obvious how to characterize diversity in this context, and a first attempt based on clustering did not produce good results. Furthermore, reinforcement learning for the reformulation task is hard in high-performance regimes. At best, it only marginally improves over the state of the art, which highlights the complexity of training models in this framework for end-to-end language understanding problems.
Thermal Percolation Threshold and Thermal Properties of Composites with Graphene and Boron Nitride Fillers

We investigated thermal properties of the epoxy-based composites with a high loading fraction - up to f=45 vol.% - of the randomly oriented electrically conductive graphene fillers and electrically insulating boron nitride fillers. It was found that both types of the composites revealed a distinctive thermal percolation threshold at the loading fraction f>20 vol.%. The graphene loading required for achieving the thermal percolation was substantially higher than the loading for the electrical percolation. Graphene fillers outperformed boron nitride fillers in the thermal conductivity enhancement. It was established that thermal transport in composites with the high filler loading, above the thermal percolation threshold, is dominated by heat conduction via the network of percolating fillers. Unexpectedly, we determined that the thermal transport properties of the high loading composites were influenced strongly by the cross-plane thermal conductivity of the quasi-two-dimensional fillers. The obtained results shed light on the debated mechanism of the thermal percolation, and facilitate the development of the next generation of the efficient thermal interface materials for electronic applications.
Venture Capitalists’ Investment decision criteria for new ventures: A Review

Venture Capitalists (VCs) play the most crucial role to identify high potential and innovative firms. However, VCs adopt different criteria to evaluate the incipient ventures before funding. The purpose of this paper is to discuss the comprehensive literature of the VCs investment evaluation criteria. This study provides a critical review of the conceptual and empirical approaches focusing on how VCs make their investment decision and what are the key influential factors at the times of investment. The critical examination highlights that not all the VCs able to follow the same investment decision process for evaluating new ventures. Some VCs give more importance to entrepreneur’s characteristics, while others are m ore intrigued with financial and marketing perspectives. Thus, findings reveal that VCs follow multi-criteria perspective of the decision-making. This study discusses the various issues and suggestions for future research. The results of the study are useful for both venture capitalists in their decision-making process and entrepreneurs in their venture capital applications to maximize their success rate.
Integration Expertise in HRI Research: A First Survey

—It is widely acknowledged that one of the deciding new challenges for robotics is applicability within unstructured, human-centered environments such as peoples homes. So far, however, this vision remains distant and autonomous systems that can socially interact with humans are rare. In order to realize them, interdisciplinary collaboration is required, so that robots are not only technically sound but also human-adequate. In this contribution, we investigate one of the main factors for building robust and useful systems: How well researchers are supported by sound software engineering methods in their interdisciplinary projects. We have surveyed researchers from Human-Robot-Interaction (HRI), and present results that show ubiquitous collaboration and signiﬁcant use of general-purpose methods. Testing, simulation and benchmarking are not widely used, however, and we present some observations on why this may be and possible steps to improve the situation. Lastly, we present preliminary experience gained with the evidence-based research approach in software engineering for robotics.
GAS REACTIONS OF CARBONS AND GRAPHITES

The following properties of carbons have been investigated: quantitative and qualitative ash analyses, interlayer spac^ing, average crystallite size, surface a,rea, pore volume distribution in pores from 20 Á to 130,000Á radius, resistivity, helium density, apparent density, porosity, and effective diffusion coefficients of hyrogen-nitrogen through the carbons. The determination of these properties and their possible relation to the gas reactions of carbons and graphites are discussed.
PURIFICATION OF TOXIC DETERMINANT LECITHINASE FROM XENORHABDUS SP. AND THEIR LARVICIDAL POTENTIAL

A symbiotic bacteria Xenorhabdus sp. was isolated from Entomopathogenic nematode Steinernema sp. using Insect bait method. This resulted in primary and secondary colony production. The primary colonies were selected for the lecithinase assay. Xenorhabdus produce various Exoenzymes in which the present study was concentrated on the exoenzyme Lecithinase which is the toxic determinant. Lecithinase activity of the bacteria was confirmed by lecithinase assay by spot inoculation of bacterial isolates on the nutrient broth supplemented with egg yolk emulsion, the opalescent zones were observed around the colonies producing the lecithinase enzyme after 24 hrs and lecithovitellin reaction was also performed by inoculating the bacterial isolates into the egg yolk broth which resulted in the formation of opalescent suspension and flocculation of particles floating in the media. Lecithinase enzyme was partially purified using Sephadex G200 column chromatography. Protein profiling of partially purified lecithinase enzyme showed a single band at 70kDa. Larvicidal activity of lecithinase was tested on Coleopteran white grub (Phyllophaga sp). It was found that with increasing concentrations of lecithinase, there was increase in mortality of the pest and vector. Thus this study confirms that the toxic determinant lecithinase can be used as potent larvicides for the control of insect pests of plants. The development of new strategies including naturally occurring larvicides to control white grub (Phyllophaga sp.) and it is important as the chemical larvicides may harm other soil dwelling organisms as well as humans. Key word: Xenorhabdus sp. , Lecithinase, larvicidal potential.
Globin Gene Switching IN VIVO PROTEIN-DNA INTERACTIONS OF THE HUMAN (cid:98) -GLOBIN LOCUS IN ERYTHROID CELLS EXPRESSING THE FETAL OR THE ADULT GLOBIN GENE PROGRAM*

To characterize the protein-DNA interactions impor- tant for the developmental control of the human (cid:98) -glo-bin locus, we analyzed by in vivo dimethyl sulfate foot- printing erythroid cells expressing either the fetal or the adult globin developmental program. In the locus control region (LCR) of the (cid:98) -globin locus, in vivo footprints on NF-E2 (or AP-1) and GATA-1 motifs remained the same regardless of whether the fetal or the adult globin genes are expressed. In contrast, in vivo foot- prints on GT (CACCC) motifs differed between the cells expressing the fetal or the adult globin program. In pro- moter regions, the actively transcribed genes demonstrated extensive and consistent footprints over the ca- nonical elements, such as CACCC and CCAAT motifs. The adult globin expressing cells displayed more exten- sive footprints than the fetal globin expressing cells in the 3 (cid:42) regulatory sequences of both the A (cid:103) - and the (cid:98) -glo-bin genes, suggesting a role of these 3 (cid:42) elements in (cid:98) -glo-bin gene expression. Our results suggest that the bulk of protein-DNA interactions that underlies the developmental control of globin genes takes place in the (cid:103) - and (cid:98) -globin gene promoters, and that GT motifs of the (cid:98) -glo-bin locus LCR in these interactions, we performed a comprehensive analysis of the in vivo interactions of sequence-specific transcription factors of the human (cid:98) -globin gene locus. Our study provides several insights into the type of interactions that occurs within the human (cid:98) -globin locus during the development of erythroid cells.

Based on the theory of Yakuzen, food as medicial treatment has affected dietary over a long history . Especially, there are food care principle which take the advantage of food taste and food character to support health care and treat the disease. Yakuzen theory is still regarded as a hypothesis. Many aspects of herbal treatments’ effectiveness remain to be clarified. Nevertheless, research results show that many rules have been advanced for foods’ associated medical roles. Kikei, one promising hypothesis, holds that food taste will play a special medicinal role in different organs. This study, using data mining techniques, particularly addresses the relation between the food taste, food character and Kikei role to extract the associated rules. Results of cluster analysis and chi-square tests show a therapeutic effect, which encourages our establishment of a systematic methodology related to food care.
Diverging Cusped-Field Hall Thruster ( DCHT ) IEPC-2007-39

An experimental cusped field Hall thruster has been developed as a test bed for exploring its viability as an alternative to more traditional magnetic arrangements in Hall thrusters. Design details and preliminary test results of the Diverging Cusped-field Hall Thruster (DCHT) are presented. The thruster design features strong magnetic cusps arranged in a divergent formation and follows from studies performed by both THALES Electron Devices and the Princeton University Plasma Propulsion Laboratory (PPL). Visual observations and current measurements of preliminary voltage scans performed at the MIT Space Propulsion Laboratory (SPL) are presented. Furthermore, thrust data collected at the Busek Company in Natick, Massachusetts are discussed. Throughout all trials the DCHT operated at power levels between 102 and 538W. A peak efficiency of 44.5% was recorded at a flow rate of 8.5sccm and 550 Volts applied to the anode. Here, the thrust measured 13.4mN and the specific impulse was 1641s. Preliminary observations of deposition profiles on the thruster walls are discussed.

The insecticidal efficacy of the diatomaceous earth formulation SilicoSec (Biofa GmbH) against adults of the rice weevil, Sitophilus oryzae, was evaluated in laboratory experiments on stored wheat. Bioassays were conducted at three temperature levels, 22, 27 and 30°C, two relative humidity (rh) levels, 55 and 65%, and four dose rates, 0.25, 0.5, 1 and 1.5 g of SilicoSec/kg of wheat. Three different aged-adult groups, 1, 2 and 7 d-old, were exposed. The mortality of exposed adults increased with the exposure interval and dose rate. Also, the increase of temperature increased S. oryzae mortality in all exposure intervals examined. The increase of rh from 55 to 65% caused a significant decrease in S. oryzae mortality. The age of the exposed individuals did not have a direct effect on SilicoSec efficacy.
Microfluidics-Driven Fabrication of a Low Cost and Ultrasensitive SERS-Based Paper Biosensor

Surface-enhanced Raman scattering (SERS) spectroscopy stands out due to its sensitivity, selectivity, and multiplex ability. The development of ready-to-use, simple, and low-cost SERS substrates is one of the main challenges of the field. In this paper, the intrinsic reproducibility of microfluidics technology was used for the fabrication of self-assembled nanoparticle structures over a paper film. The paper SERS substrates were fabricated by assembling anisotropic particles, gold nanostars (GNSs), and nanorods (NRs) onto paper to offer an extra enhancement to reach ultra-sensitive detection limits. A polydimethylsiloxane PDMS-paper hybrid device was used to control the drying kinetics of the nanoparticles over the paper substrate. This method allowed a high reproducibility and homogeneity of the fabrication of SERS substrates that reach limits of detection down to the picomolar range. This simple and low-cost fabrication of a paper-based sensing device was tested for the discrimination of different cell lineages.
A Multi-Language Comparison Of Influences On Author Verification Using Character N-Grams

Character N-Grams have been shown to capture markers of an authors writing style, for multiple languages. In this thesis hypotheses about writing style are evaluated based on medium-sized comments left on Wikipedia talkpages, employing a language independent character n-gram algorithm. Noise introduced by topic alignment, time disalignment and language differences are evaluated and quantified. We create a new corpus for author verification, which is more than 5 times larger than the largest currently used corpus for authorship research, and more than 100 times larger than corpora recently used in author verification benchmarking tasks. We investigate whether character n-gram techniques capture the writing style of languages with similar roots with similar precision. The results indicate that author verification works similarly for different languages, but does not show a more significant correlation for languages with similar roots. The influence of noise from topic alignment is investigated by studying author verification precision for texts about different topics, and texts about similar topics. The results show that topic does indeed introduce noise, and topic alignment makes differences between authors more visible. Finally we investigate how much the writing style of an author changes over time, hypothesizing author verification is easier for texts written within a short time frame. The results show a significant reduction in precision when the time between two texts increases.
Generation and Growth of Vertical Cracks by Scribing

Study on Laser Braking of Glass Plate (lst Report) Generation and Growth of Vertical Cracks by Scribing Masayuki IKEI)A, Takayuki SHIBATA, Eiji MAKINO. Yoshimi TAKAHASHI, Atsushi ONO and Fumio MATSUMOTO The demand of liquid crystal display panels for handy type personal computers etc. have been remarkably increased. Liquid crystal display panels were generally formed on glass substrates. In these production process, precise arid fine cutting of glass plates is very important because of the final manufacturing process. Hard and brittle materials like glass plates are conventionally cut by growing vertical cracks. They are generated by scribing with a diamond point or a rotating chisel under optimum load and grown by applying mechanical force onto the scribed trace successively. In the laser braking method, vertical cracks formed on glass plates are grown by tensile stress due to thermal expansion which arises from temperature rise by a CO2 laser beam irradiation onto the scribed trace. High quality and high speed breaking can be achieved without applying mechanical force. In this breaking process, formation of fine vertical cracks by scribing is indispensable. This paper deals with the effect of scribing conditions on features of scribed trace and the vertical crack length experimentally and theoretically. Generation and growing process of vertical cracks were observed. Close agreement of vertical cracks length grown between observed and calculated values was obtained.
Exploring Linguistic Features for Cross-document Named Entity Disambiguation

In natural language processing, named entities are important components. However, due to various ways of writing, named entities have multiple surfaces in texts, e.g., ‘Big Blue’ and ‘IBM’. Moreover, different entities can share the same surface. For example, ‘New York’ as a place name has dozens of different referents in Wikipedia. Thus, crossdocument named entity disambiguation is the task of identifying whether a mention refers to a certain entity and linking mentions in different documents to their corresponding entires in a large-scale knowledge base. Disambiguating named entities relies on context information obtained from source documents and knowledge base texts.
A DIFFUSION EQUATION BASED ALGORITHM FOR DETERMINATION OF THE OPTIMAL NUMBER OF FIBERS USED FOR BREAST CANCER TREATMENT PLANNING IN PHOTODYNAMIC THERAPY АЛГОРИТМ ОПРЕДЕЛЕНИЯ ОПТИМАЛЬНОГО ЧИСЛА ВОЛОКОН ИСПОЛЬЗУЕМЫХ ПРИ ВНУТРИТКАНЕВОЙ ФОТОДИНАМИЧЕСКОЙ ТЕРАПИИ РАКА МОЛОЧНОЙ ЖЕЛЕЗЫ НА ОСНОВАНИИ ДИФФУЗИО

It is essential in interstitial Photodynamic therapy (iPDT) treatment planning to ensure a homogeneous distribution within a tumor volume using cylindrical diffusing fibers while keeping the surrounding tissue intact. Light distribution is simulated through two algorithms based on the diffusion equation assuming diffusers as light sources. The first algorithm analyzes the diffusion equation and studies the effects of different variables (optical properties, delivered power, diffuser length, and position). Next, optical properties of breast were applied to estimate the volume that receives accepted light dose from one diffuser. In the second algorithm, multiple diffusers were simulated in order to find the relation between the volume and the number of required diffusers which are needed to cover cubical or cylindrical volume with sufficient light dose. Throughout this study, real values of optical properties, clinical laser power, and treatment time were considered to evaluate sufficient light doses. This study is in agreement with previous works in that optical properties are the major factors influencing light distribution in iPDT. It is shown that for a homogeneous phantom mimicking breast cancer and cubical or cylindrical shape, the number of required fibers N equal W×L or D 2 respectively.
The Relation Between Idiosyncratic Volatility and Returns for U.S. Mutual Funds

Theoretically the relation between returns and idiosyncratic volatility should be non-existent or positive. Many empirical studies confirm this but Ang, Hodrick, Xing and Zhang (2006) contest the conventional view and find a negative relationship for a sample of U.S. firms. I contribute to the field by investigating the relation for a sample of U.S. mutual funds. The sample consist of a total of 10 917 equity mutual funds, the funds are divided in to four different classes depending on equity focus (growth, value, small cap and large cap). Data were collected for the period 1995 to 2015. Ang et al. (2006) relate returns with lagged idiosyncratic volatility making the implicit assumption that idiosyncratic volatility can be described as a random walk. But as Fu (2009) I find that this is not true and use an AR(2) model to estimate idiosyncratic volatility, inspired by Chua, Choong Tze, Jeremy Goh, and Zhe Zhang (2010). The idiosyncratic volatility is estimated relative to the Carhart (1997) four- factor mode and divided in to an expected and unexpected part as in Chua et al. The relation is examined using Fama-MacBeth (1973) regressions with both gross return and the Carhart alpha as dependent variables. The results suggest a positive relation only when using the Carhart alpha as dependent variable and all the control variables. Otherwise the results are inconclusive. As an additional robustness test I perform portfolio sorting on EIV without control variables and get results that suggest a negative relation.
