Search Cost , Smartphones , and Consumer Choice : Evidence from Korean Gasoline Market

The Korean government has been publishing daily prices of all gasoline stations on a publicly available website since 2008. Combined with the rapid increase of the smartphone user population after 2009, this price information service has changed the consumer search environment significantly. I study the effects of these technology advances on price and markup dispersion among gasoline stations. Using daily price data of three regions from January 2010 to June 2012, I find that price and markup dispersion among gasoline stations tend to increase when the smartphone penetration rate increases. I utilize structural estimations of the two-type consumer search model to find that the proportion of searchers among consumers increases as the smartphone penetration rate increases. These findings suggest that the increase of smartphone users not only changed how consumers search, but also affected how gasoline stations compete and set prices. Empirical markup distributions provide some evidence that is consistent with the bimodal distribution result of the Stahl model.
Genetic markers associated with clinical and radiographic response in adalimumab plus methotrexate- or methotrexate-treated rheumatoid arthritis patients in OPTIMA.

Objectives Biologics, including tumour necrosis factor inhibitors such as adalimumab (ADA), have significantly improved outcomes in rheumatoid arthritis (RA). Because the clinical course of RA and response to therapy may be influenced by the genetic background of the patient, the objective of this retrospective parallel-assigned case-control analysis was to evaluate the associations between candidate genetic markers for RA with clinical and radiographic responses to ADA + methotrexate (MTX) or MTX monotherapy in the Optimal Protocol for Treatment Initiation with MTX and ADA (OPTIMA) study. Methods Three candidate genetic markers were tested: HLA-DRB1 shared epitope (SE), interleukin 4 receptor (IL4R) single nucleotide polymorphism (SNP) rs1805010, and Fc gamma receptor IIb (FcgRIIb) SNP rs1050501. Genetic associations with week 26 clinical and radiographic responses during treatment with ADA + MTX or MTX monotherapy were assessed using summary statistics, chi-square or Fisher's exact test, correlation, regression models, and corrected for multiple-comparisons. Results Low disease activity (p=0.008) and improvement in American College of Rheumatology 20%, 50% and 70% response criteria (p=0.02, 0.01, and 0.02, respectively) were associated with HLA-DRB1 SE copy numbers in the ADA + MTX treatment arm, and the FcgRIIb SNP was a predictor of remission. The IL4R SNP correlated with radiographic progression in patients receiving MTX monotherapy, supporting previous findings. Conclusions This pharmacogenetic analysis identified genetic components that contribute to clinical responses to anti-rheumatic therapy.
An Implementation of Vineent ' s Theorem

Isolation of the real roots of a polynomial equation (or, simply, isolation) is the process of finding real, disjoint intervals such that each contains exactly one real root and every real root is contained in some interval. This process, in itself, is of great interest and use in several areas; as an example we mention Tarskrs decision method 1-16]. In this paper we shall restrict our atten(ion to those isolation methods which have been implemented in computer algebra systems using exact (infinite precision) integer arithmetic algorithms. (For a survey of computer algebra systems see [14].) When we use exact integer arithmetic then, in analyzing an algorithm, the "cost" of an operation on two integers depends not only on the operation itself but on the length (number of bits) of the operants as well. If A is an integer, we define L(A), its length, by
Model Based on Neural Network

Poetry is a special and important cultural heritage in human history. The arrival of the era of big data and the development of deep learning technology have promoted the innovation of algorithm design ideas in the field of artificial intelligence. Deep learning has also developed greatly in poetry generation technology. Even to a certain extent, poetry produced may be difficult for ordinary people to distinguish. However, at present, poetry generation technology still focus on poetry avoid of thoughts and feelings and human spirituality. The work of machine poetry began in the 1970s. The traditional method of poetry generation relies heavily on the professional knowledge of the field of poetry. It requires experts to design a large number of artificial rules to constrain the rhythm and quality of the generated poetry. With the development of deep learning technology, the study of poetry generation has entered a new stage. Many methods of poetry generation based on deep learning have been proposed, such as the method based on RNN language model, the framework based on encoder-decoder, and the method of poetry generation based on GAN. This paper needs to modify this reality from human writing. Based on the iterative polishing mechanism proposed by Rui Yan et al., it adds a more perfect poetry evaluation system and proposes intelligent writing based on deep learning that can be automatically modified for multiple times. The poetry model, after trial and manual evaluation, proves that the method has certain effects.
INCREASING ENERGY EFFICIENCY FOR INTEGRATING SMALL SCALE PV POWER GENERATION TO GRID SYSTEM

The use of renewable energy resources is increasing day by day, and the importance of solar energy is increasing and photovoltaic energy conversion is taking place in micro-networks. Therefore, it is important to take power at high level in photovoltaic systems. The electrical energy produced by the PV panels varies depending on the radiation and temperature, and in some cases this energy is not sufficient for the maximum power transfer of the micro-inverter. The maximum power transfer level of the inverter is increased by providing battery support near the input voltage at which the micro-inverter can deliver maximum power. The output power of the PV system is constantly measured by means of sensors, and the inverter input voltage range near enough to the gentle is kept at a certain level by the microprocessor and the proposed algorithm and PV system efficiency has been increased this
Performance, resources and capabilities of construction organisations: The mediating role of competitive strategies

This study examines the relationships between competitive strategies, resources/capabilities and organisational performance in construction organisations. The main objective is to establish the mediating role of competitive strategies on the strength of relationship between resources, capabilities and performance of large construction business organisations in South Africa. A survey instrument was administered to Grades 7, 8 and 9 construction organisations listed in the Construction Industry Development Board (cidb) database. 72 usable questionnaires were analysed using descriptive statistics and correlations. The results show that organisational resources and capabilities do not exert a direct impact on performance of construction organisations, but technological resources showed significant relationship, when mediated by competitive strategy. This implies that performance of large construction organisations is contingent upon their competitive strategies and organisational capabilities, for them to achieve performance excellence. Furthermore, differentiation strategy influences an organisations’ financial performance negatively whereas cost-leadership strategy has a positive impact. It provides empirical evidence on the relationship between competitive strategy and organisational resources/capabilities in a new setting.
When can abundance surveys be analysed with “ design-based ” methods ?

The IWC Scientific Committee (SC) often has to consider abundance estimates derived from line transect surveys which have been analysed using “design-based estimators”, but where for various reasons it is not clear whether the resulting estimates of abundance and uncertainty are trustworthy for, say, RMP purposes. The SC has therefore in recent years (up to 2016) considered revising its formal Guidelines1 to take advantage of methodological developments, in particular the increased flexibility o↵ered by“model-based”abundance estimates, constructed statistically around smooth estimates of animal density across space. As background for that revision, document IWC/65b/RMP11 (Hedley & Bravington 2014) describes the randomization assumptions required by design-based principles; it also introduces some of the practical issues around model-based estimates, which are more flexible but also more complicated to implement. In section 11 of that document, the authors note that it may sometimes be possible to derive acceptable estimates of abundance and uncertainty using a design-based calculation— which in this document we call an HT (“Horvitz-Thompson-like”) estimate— even when the underlying design-based assumptions are not strictly met, provided that (among other things) realised coverage is su ciently even. This has been common practice at IWC and elsewhere, but generally on an ad hoc basis with no clear criteria for “how bad is too bad? ”. For such cases, IWC/65b/RMP11 recommends instead that HT acceptability needs to be verified on a case-by-case basis, using diagnostics derived from model-based analysis. This document follows up on that suggestion. We briefly review the main di↵erences between HT and model-based estimates (section 2), explain where problems can occur with the former (3), and through simulation demonstrate those problems and how they might be checked for using model-based criteria (sections 4, 5). The idea is to consider a range of scenarios about underlying density gradients, then fit di↵erent spatial models (including a “null model” that is equivalent to an HT estimate) to data simulated from the actual survey tracks and each density scenario, then check the consistency of point estimates and variance estimates across the di↵erent models. Software implementing these criteria/checks is available as an accompanying R package.
ect of Acid / Ethanol Ratio on Medium Chain Carboxylate Production with Di ff erent VFAs as the Electron Acceptor : Insight into Carbon Balance and Microbial Community

Medium chain carboxylates (MCCs) are important precursors for biodiesel production. Using chain elongation to produce MCCs is an emerging bioenergy technology. In this study, batch tests were conducted to investigate fermentative MCC production through chain elongation from acetate, propionate, n-butyrate, and ethanol. The effect of the acid/ethanol ratio on MCC production by mixed culture was investigated. Better MCC production, especially n-caproate production, was achieved at optimal acid/ethanol ratios of 1:4, 1:3, and 1:2 with acetate, propionate, and n-butyrate as the electron acceptor, respectively. The n-caproate concentration was high, up to 41.54 mmol/L, and the highest n-caproate production efficiency was 57.96% with the n-butyrate/ethanol ratio of 1:2. The higher concentration of ethanol might stimulate the growth of chain elongation bacteria to promote chain elongation. The highest MCC production efficiency with different electron acceptors corresponded to less carbon loss and a higher chain elongation degree. In addition, with the optimal acid/ethanol ratio, the substrate was maximally utilized for chain elongation. The microbial community analysis confirmed the carbon balance analysis with the maximum relative abundance of 52.66–60.55% of the n-caproate producer Clostridium_sensu_stricto_12 enriched by the optimal acid/ethanol ratios with different volatile fatty acids (VFAs) as electron acceptors.
Improved aerosol forecasting during extreme events by data assimilation

It is then very important to well simulate the tridimensional distribution of different type of aerosols within the chemistry and transport models (CTMs). Nevertheless, modelling of different type of aerosols is challenging and still subject of many uncertainties due to the complexity of their physical/chemical transformations and the approximations in the parameterizations of their sources/sinks. The improvements of the models can be achieved by means of i) improvements of the physical parameterizations of the aerosols (e.g., Sic et al., 2015, and ii) using data assimilation of aerosol products such as Aerosol Optical Depth (AOD) (e.g., Sic et al., 2016) and lidar backscatter/extinction profiles.
MRSE in Cloud Data using Coordinate Matching & Inner Product Similarity

Cloud computing is the emerging technology, in which storage and retrieval of sensitive data information are incremented in utilization. The efficacious data access control should be done in the efficacious access controlled manner through which one provide a better security. The key work search retrieval over the encrypted cloud data’s are involute and tedious process which need to more concern to ameliorate the utilize amicable environment while probing for a data over an encrypted data. In this paper, for the first time, we define and solve the conundrum of privacy-preserving multi-keyword ranked search over encrypted data in cloud computing (MRSE). We establish a set of stringent privacy requisites for such a secure cloud data utilization system. Among sundry multi keyword semantics, we cull the efficient homogeneous attribute measure of “coordinate matching”, i.e., as many matches as possible, to capture the pertinence of data documents to the search query. The proposed methodology proves that the keyword search retrieval is done efficaciously over the encrypted cloud data’s with the consideration of privacy requisites. The experimental results prove that the proposed methodology is better than the already subsisting methodologies.
Verification and Validation Experience of Safety-grade Optical Modem for Core Protection Calculator ( CPC )

In general, an optical modem used in industry is composed of an integral system for the Transmitter/Receiver. However, a safety-grade optical communication modem in a nuclear safety system is composed of send-only service or receive-only service. A send-only optical modem of the control rod signal transmission is in charge of the transmitting function in the form of frequency-converted optical signals to the receive-only optical modem as frequency-converted optical signals in the range of an input voltage of 0V to 10V. The receive-only optical modem of the control rod signal receiving is in charge of the receiving function toward the Analog Input (AI) Gate through the Core Element Assembly Computer (CEAC) Analog Input (AI) Surge card in the form of frequency-converted optical signals to the sending-only optical modem as frequency-converted optical signals in the range of an input voltage of 0V to 10V. This paper describes the results of a software verification and validation for a send-only optical modem and receive-only optical modem, respectively. All tests were performed according to the test plan and test procedures. Functional testing, performance testing, event testing, and scenario-based testing for a safety-grade optical modem of a Core Protection Calculator in a Korea Standard Nuclear Power Plant as a thirty-party verifier was performed successfully.

Consumer-Oriented ReceiptLog Service Platform for Effective Applications

Although purchase history has been used by enterprise, it also contains valuable information for consumers. This paper develops Receipt Log Service Platform, where every user can store the purchase history from own receipts (we call Receipt Log), and can use the data for various consumer services. The proposed platform consists of three components: receipt scanner, ReceiptLog DB and ReceiptLog API. The receipt scanner digitizes daily receipts, and the ReceiptLog DB manages the scanned data. The ReceiptLog API provides the Receipt Log as a service. The API consists of the basicAPI providing fundamental access for the Receipt Log, whereas the miningAPI performing statistical analysis over the Receipt Log. These APIs are published as Web services, which can used by multiple applications and services for various purposes. also implement two applications using the proposed platform. The one is “Sma-sho”, which supports user’s shopping with receipt log. The other is “ReciLog”, which shares receipts within community. For each of the applications, we conduct experimental evaluation with actual subjects, in order to see the usefulness of services with Receipt Log. Keywords—receiptlog, Web services, database, social network service
Project notes of CLARIN project DiscAn : Towards a Discourse Annotation system for Dutch language corpora

Although discourse is a crucial level in language and communication, many existing corpora of Dutch language lack annotation at this level. This paper describes the recently started DiscAn project, which sets the first step to change this situation for Dutch, in line with international tendencies. The project has five main goals: 1) to standardize and open up an existing set of Dutch corpus analyses of coherence relations and discourse connectives; 2) to develop the foundations for a discourse annotation system that can be used in Dutch natural language corpora; 3) to improve the metadata within European research infrastructure project CLARIN by investigating existing CMDI profiles or adding a new CMDI profile specially suited for this type of analysis; 4) to inventorize the required discourse categories and investigate to what extent these could be included in ISOcat categories for discourse that are currently being developed; 5) to further develop an interdisciplinary discourse community of linguists, corpus and computational linguists in The Netherlands and Belgium, in order to initiate further research on cross-linguistic comparison in a European context.
UNIFORM MODELS AND METHODS FOR GRAY-SCALE TRANSFORMATION OF DIGITAL IMAGES

At present, the models and methods of gray-scale transformation (gradation correction) are used for solving of a series of important problems of digital image pre-processing. As a rule, the gray-scale transformation methods are used for a tone correction of an image with the aim to lighten it, or to darken [1 – 4]. Most often, for solving this problem these are used a polynomial, sinusoidal, exponential, or logarithmic gray-scale transformation model of the following type p(x) x  ; (1)
Nominal Exchange Rates and Prices: Evidence from Taiwan

Economic theories postulate that the nature of relationship between the Nominal Exchange Rate and Prices (domestic and foreign) are linearly related. We investigate this using information from Taiwan and adopted data driven methods in establishing the true nature of the relationship that exists between the Nominal Exchange Rate and the Domestic Prices and we discovered a nonlinear relationship and a 0.25% foreign price pass-through effect on the Nominal Exchange Rate of Taiwan.
Up-regulated transforming growth factor β–inducible gene h3 in rheumatoid arthritis mediates adhesion and migration of synoviocytes through αvβ3 integrin: Regulation by cytokines

Objective To delineate the expression of transforming growth factor β–inducible gene h3 (βIG-H3) in rheumatoid synovitis and to determine the regulatory role of βIG-H3 in the adhesion and migration of fibroblast-like synoviocytes (FLS). Methods Synovial tissue was obtained from patients with rheumatoid arthritis (RA) during joint replacement surgery, and FLS were isolated using enzymatic treatment. Immunohistochemical staining was performed to show the expression of βIG-H3 within rheumatoid synovium. Synthesis of βIG-H3 from FLS was determined by semiquantitative reverse transcription–polymerase chain reaction, Western blot analysis, and enzyme-linked immunosorbent assay. Cell adhesion and migration assays were performed using the YH18 peptide in the fourth fas-1 domain of βIG-H3 and function-blocking antibodies to integrins. Results Expression of βIG-H3 was up-regulated in RA synovial tissue compared with synovial tissue from patients with osteoarthritis. FLS isolated from RA synovial tissue constitutively produced βIG-H3, which was up-regulated by transforming growth factor β1, interleukin-1β, and tumor necrosis factor α. Although FLS expressed a variety of integrins, βIG-H3 mediated adhesion and migration of FLS through interaction with αvβ3 integrin. Cytokines failed to affect the βIG-H3–mediated adhesion. However, migration of FLS guided by βIG-H3 was enhanced by interferon-γ and platelet-derived growth factor type BB. The YH18 peptide in the fourth fas-1 domain of βIG-H3 inhibited adhesion and migration in a dose-dependent manner. Conclusion The results suggest that βIG-H3, which is abundantly expressed in RA synovial tissue, plays a regulatory role in chronic destructive inflammation through the modulation of the adhesion and migration of FLS. This finding indicates the relevance of βIG-H3 and αvβ3 integrin–interacting motifs as potential therapeutic targets in this disease.
Test-case number 10 : Parasitic currents induced by surface tension ( PC ) March 2003

The assessment of the consistency of a numerical model is proposed by comparison to theoretical results. The surface tension modeling is tested thanks to two analytical test cases. The first problem consists in verifying the equilibrium of a cylindrical drop initially at rest. The pressure in the drop is defined analytically (Laplace law). In the second test, an initially square cylindrical drop is oscillating under surface tension forces. The viscous damping of drop oscillations around a cylindrical shape is studied in order to reach a steady cylindrical final state corresponding to the Laplace problem. The oscillation frequency is known theoretically. The aim of the the two cases is to estimate the discretization error on the curvature of a free surface leading to the generation of parasitic numerical currents.
