1 Size-dependent change in body shape and its possible ecological role in the Patagonian squid ( Doryteuthis 1 gahi ) in the Southwest Atlantic 2 3

19 Cephalopods are a versatile group with several mechanisms in place to ensure the success of future generations. 20 The Patagonian long-finned squid (Doryteuthis gahi) populations on the southern Patagonian shelf are believed 21 to be genetically homogenous but mechanisms connecting them geographically and temporally are unresolved. 22 Individual growth is highly variable within cephalopod populations and is likely to affect individual patterns of 23 migration and, thus, population connectivity as a whole. Therefore, this study aimed to make inferences about 24
Phase I-Evaluation of a Functional Interconnect System for Solid Oxide Fuel Cells Final Topical Report Reporting Period : July 1 , 2005 – September

This project is focused on evaluating the suitability of materials and complex multi-materials systems for use as solid oxide fuel cell interconnects. ATI Allegheny Ludlum has generated promising results for interconnect materials which incorporate modified surfaces. Methods for producing these surfaces include cladding, which permits the use of novel materials, and modifications via unique thermomechanical processing, which allows for the modification of materials chemistry. The University of Pittsburgh is assisting in this effort by providing use of their in-place facilities for dual atmosphere testing and ASR measurements, along with substantial work to characterize post-exposure specimens. Carnegie Mellon is testing interconnects for chromia scale spallation resistance using macro-scale and nano-scale indentation tests. Chromia spallation can increase electrical resistance to unacceptable levels and interconnect systems must be developed that will not experience spallation within 40,000 hours at operating temperatures. Spallation is one of three interconnect failure mechanisms, the others being excessive growth of the chromia scale (increasing electrical resistance) and scale evaporation (which can poison the cathode). The goal of indentation fracture testing at Carnegie Mellon is to accelerate the evaluation of new interconnect systems (by inducing spalls at after short exposure times) and to use fracture mechanics to understand mechanisms leading to premature interconnect failure by spallation. Tests include bare alloys from ATI and coated systems from DOE Laboratories and industrial partners, using ATI alloy substrates. West Virginia University is working towards developing a cost-effective material for use as a contact material in the cathode chamber of the SOFC. Currently materials such as platinum are well suited for this purpose, but are cost-prohibitive. For the solid-oxide fuel cell to become a commercial reality it is imperative that lower cost components be developed. Based on the results obtained to date, it appears that sterling silver could be an inexpensive, dependable candidate for use as a contacting material in the cathode chamber of the solid-oxide fuel cell. Although data regarding pure silver samples show a lower rate of thickness reduction, the much lower cost of sterling silver makes it an attractive alternative for use in SOFC operation.
Purification of the Major Protein-tyrosine-phosphatases of Human Placenta*

This report describes the purification of the major protein-tyrosine-phosphatases from human placenta. Enzyme activity was followed with a novel artificial substrate, namely reduced, carboxamidomethylated, and maleylated lysozyme, phosphorylated on tyrosine by a partially purified preparation of insulin and epidermal growth factor receptor kinases, also from human placenta. The key step in the purification of the protein-tyrosine-phosphatases was affinity chromatography on a column of thiophosphorylated, reduced, carboxamidomethylated, and maleylated lysozymeSepharose, Purification was carried out separately from both the soluble and particulate fractions. Whereas multiple and distinct enzyme forms were obtained from each of these, little difference could be detected between the behavior of the “soluble” enzyme subtypes and their “particulate” counterparts. The major subtypes were purified to apparent homogeneity with an -23,000-fold enrichment and 10% yield from the soluble fraction and a 4,300-fold enrichment and 13% yield from the particulate fraction. Both samples migrated as bands of 35 kDa on sodium dodecyl sulfatepolyacrylamide gel electrophoresis and had specific activities of -45,000 nmol of Pi released min” mg-’, at least 2-3-fold higher than that of the type 1 and 2A serinelthreonine phosphatases. The level of proteinty ros ine-phosphat~ in the soluble fraction of human placenta (2,000 units/g of protein) was approximately the same as protein-serine/threonine-phosphatases 1 and 2A in skeletal muscle.
Impact of Corporate Diversification and Segment Reporting on Stock Price Crash Risk

We show that diversified firms, compared to focused firms, display lower future stock price crash risk. We also investigate the impact of SFAS No. 131, the accounting standard on disclosure about segment financial data. Using difference-in-differences design, we provide evidence that focused firms, which changed their reporting by disclosing multiple segments post-SFAS No. 131, experienced a significant immediate (within two years) decline in future stock price crash risk. Our results further show that diversified firms, which disclosed more segments and new information post-SFAS No. 131, on average, did not experience a significant immediate (within two years) change in future stock price crash risk. However, diversified firms that changed their disclosures by a higher level or an increase in information disaggregation post-SFAS No. 131 revealed stockpiled bad news immediately upon adopting SFAS No. 131 and experienced an increase in crash risk within two years post-SFAS No. 131. The results collectively show that while the difference in crash risk between diversified and focused firms is significantly reduced due to SFAS No. 131, marginal difference in crash risk remains. Our findings collectively support the information transparency effect of corporate diversification on information asymmetry and that SFAS No. 131 significantly increased information transparency, thereby reduced bad news hoarding as implied in future stock price crash risk.
L2‐signatures, homology localization, and amenable groups

Aimed at geometric applications, we prove the homology cobordism invariance of the L2‐Betti numbers and L2‐signature defects associated to the class of amenable groups lying in Strebel's class D(R), which includes some interesting infinite/finite non‐torsion‐free groups. This result includes the only prior known condition, that Γ is a poly‐torsion‐free abelian group (or a finite p‐group). We define a new commutator series that refines Harvey's torsion‐free derived series of groups, using the localizations of groups and rings of Bousfield, Vogel, and Cohn. The series, called the local derived series, has versions for homology with arbitrary coefficients and satisfies functoriality and an injectivity theorem. We combine these two new tools to give some applications to distinct homology cobordism types within the same simple homotopy type in higher dimensions, to concordance of knots in three manifolds, and to spherical space forms in dimension 3. © 2012 Wiley Periodicals, Inc.
www.econstor.eu Inequality in minimum-effort coordination∗

Successful coordination is key for economic and societal wealth. The rich literature on the minimum-effort game (MEG) has provided valuable insights into coordination, both theoretically and empirically. Yet, although real-world scenarios often involve asymmetric benefits and/or costs from coordination, most previous studies rely on symmetric MEGs. We investigate the effect of unequal equilibrium payoffs in the MEG. In two experiments, we observe that players are better able to coordinate on an equal rather than an unequal Pareto-dominant equilibrium. We find that the ability to coordinate on the unequal Pareto-dominant equilibrium critically hinges on the costs of miscoordination for the player who benefits most from successful coordination: when her costs are low, she seems able to stabilize the Pareto-dominant equilibrium even if payoffs are highly unequal, whereas coordination success worsens substantially when her costs are high.

University of Alberta Automated Essay Scoring Framework for a Multilingual Medical Licensing Examination by

Automated essay scoring (AES) is a technology that efficiently and economically score written responses by emulating intelligence of human scorer. Present study had employed open-source Natural Language Processing technologies for developing AES framework, to score multilingual medical licensing examination. English, French, and translated-French responses of constructed-response items were scored automatically, and the strength of multilingual automated scoring framework were evaluated in relation to human scoring. Machine-translation was also contextualized for raising AES performance, when restricted sample size counters the performance of AES software. Specific feature extraction and model building strategies resulted in high concordance between AES and human scoring, with average maximum human-machine accuracy of 95.7%, which was in almost perfect agreement with human markers. Results also revealed that the machine-translator had raised predictive consistency but negatively influenced the predictive accuracy. Implications of results for practice, as well as directions for future research are
TWTRENDS: THE TOPIC-GRAPH EXTRACTION FROM TWITTER TRENDS

Twitter provides a list of trending topics, a list of social trends or issues that users of the social networking services (SNS) will be interested in at a given time. However, they are presented as a list of key phrases making it challenging to identify or infer the message of the trending topics. In an attempt decipher the meaning and the structure hidden in the list of trending topics provided by Twitter, we developed a system to visualize topic maps according to the co-occurrence structure of typical tweets that mention the trending topics. This paper describes an overview of the system structure, the main logic to construct topic maps, and findings from its operation from the 1 st of January 2019 to 30 th of June 2019.
Anticipated backward doubly stochastic di(cid:27)erential equations driven by teugels martingales with or without re(cid:29)ecting barrier

We are interested in this paper on re(cid:29)ected anticipated backward doubly stochastic di(cid:27)erential equations (RABDSDEs) driven by teugels martingales associated with Levy process. We obtain the existence and uniqueness of solutions to these equations by means of the (cid:28)xed-point theorem where the coe(cid:30)cients of these BDSDEs depend on the future and present value of the solution ( Y, Z ) . We also show the comparison theorem for a special class of RABDSDEs under some slight stronger conditions. The novelty of our result lies in the fact that we allow the time interval to be in(cid:28)nite.
GIS Technologies and their Environmental Applications 253

In environmental applications such as forestry, the capture of the polygonal structuring of the data is expensive in terms of hardware, software and labour due largely to difficulties in constructing a topologically complete map. This paper will show that, for many applications, topological structuring and data entry methods may be made quite simple. The example used is a paper map of forest polygons. The map must usually have the relevant polygons digitized manually, but instead of drawing individual boundaries to be connected later the operator is instructed to draw around the interior of each polygon in turn, generating a set of'fringe' points labelled with the relevant polygon's number. If the map has no other information on it then it may be scanned instead, and saved as an image. Simple image processing techniques may be used to generate fringe points as in the manual process. Polygon boundaries are generated by first creating the Voronoi diagram of these fringe points. These triangle edges are examined in a single-pass 'visibility order' to extract the Voronoi cell edges only between fringe points with differing labels. These edges are connected with no topological errors, They may be exported to a CIS as arcs, or preserved internally for polygon labelling and other processing. Both Voronoi cells and extracted arcs are saved internally using the QuadArc, a modification of the Quad-Edge data structure, which is guaranteed to manage connected graphs on the manifold using just two operators. In an objectoriented language the data structure management is only a few lines of code, giving a simple and elegant approach to topology management.

Kobe University Repository : Kernel タイトル Tit le Cloning of a gene encoding 4-amino-3-hydroxybenzoate 2 , 3-dioxygenase from Bordetella sp

Bordetella sp. 10d produces a novel dioxygenase catalyzing the meta-cleavage of 4-amino-3-hydroxybenzoic acid, 4-amino-3-hydroxybenzoate 2,3-dioxgenase (4A3HBA23D). A gene encoding 4A3HBA23D was cloned and named ahdA. The deduced amino acid sequence of ahdA showed 29.2-24.2% identities to those of prokaryotic and eukaryotic 3-hydoxyenzoate 3,4-dioxygenases in reported meta-cleavage dioxygenases. However, no identities were observed in the amino terminal sequences of the first 29 amino acid residues. An ORF was found downstream of ahdA. The deduced amino acid sequence of the ORF showed identities to those of LysR family regulators involved in protocatechuate metabolism, and contained motifs conserved in the regulators. On the basis of these results, the ORF was named ahdR encoding a putative LysR family regulator. The transcription start point of ahdA was localized 414-bp upstream of the start codon of ahdA. Two DNA-binding motifs of LysR family regulators were found upstream of the transcription start point. These observations suggest that a LysR family regulator encoded by ahdR regulates the expression of ahdA.
Load Flow Analysis for Radial Distribution Networks Using Backward/Forward Sweep Method

Power flow analysis is important for the performance’s evaluation of operational conditions of electric power system and the planning of its future upgrading. The radial distribution networks RDN are characterized by load unbalances and high R/X ratios making the Newton Raphson and Fast Decoupled methods to fail in the analysis. In this work, the backward and forward sweep method was proposed as an efficient and easy tool for Radial Distribution Network analysis. The sweep path is based on Kirchhoff’s voltage and current laws. The method was tested on the IEEE 33 bus radial test systems with different load scenarios under MATLAB and the results comparison has shown better voltage profile and accurate line power losses.
Knowledge and Anchoring: Verification of Three Circumstances in Which Knowledge Does Not Interfere with Anchoring

Many researchers have demonstrated that those people with higher knowledge are less subject to the impact of a given anchor. In real life, however, a situation might be quite complicated and not simply a question of an existing high (or low) anchor. We have designed four tests to demonstrate the relation between knowledge and anchoring. We hold that only in general situations can knowledge interfere with the anchoring effect. Study 1 was used to demonstrate this hypothesis. The research result in turn served as the foundation for our follow-up studies. Based on this foundation, we conducted three experiments to demonstrate that, when faced with a complicated and difficult estimation that must be completed within a short period of time (Study 2), when the source of information possesses a high degree of reliability (Study 3), and when practical experience is lacking (Study 4), the anchoring effect will still exert influences on people with higher knowledge.

RELATIONSHIP BETWEEN VOLATILITY OF STOCK MARKET ILLIQUIDITY AND EXCHANGE RATE VOLATILITY: THE CASE OF BORSA ISTANBUL

Low liquidity (illiquidity) of a market is considered to have important asset pricing implications such that the higher the transaction costs the lower will be the asset prices and higher the rates of return. This is due to an illiquid asset offering higher rate of return to compensate the investors for having liquidity cost. According to John Maynard Keynes, an asset is defined to be liquid when "it is more certainly realizable at short notice without loss". The major aim of this paper is to analyze the relationship between exchange rate volatility and volatility of stock market illiquidity for Borsa Istanbul. In this way the effects of external shocks and the exchange rate volatility as the risk indicator for an open economy will be investigated. Volatility of stock market illiquidity and exchange rate volatility are estimated by applying different approaches available in the relevant literature. Afterwards the relationship between these two variables is analyzed by using Moon and Yu approach. Based on empirical findings some policy recommendations are made for market players.
Diagonal dominance of damping and the decoupling approximation in linear vibratory systems

A common approximation in the analysis of non-classically damped systems is to ignore the off-diagonal elements of the modal damping matrix. This procedure is termed the decoupling approximation. It is generally believed that errors due to the decoupling approximation should be negligible if the modal damping matrix is diagonally dominant. In addition, the errors are expected to decrease as the modal damping matrix becomes more diagonally dominant. It is shown numerically in this paper that, over a ﬁnite range, errors due to the decoupling approximation can increase monotonically at any speciﬁed rate while the modal damping matrix becomes more diagonally dominant with its off-diagonal elements decreasing continuously in magnitude. An explanation for these unexpected drifts of decoupling errors is provided with the use of complex coupling coefﬁcients. Small off-diagonal elements in the modal damping matrix are not sufﬁcient to ensure small errors due to the decoupling approximation. Any error-criterion based solely upon the diagonal dominance of the modal damping matrix would not be accurate.
Asymptotic analysis and numerical modeling of mass transport in tubular structures

In the paper the flow in a thin tubular structure is considered. The velocity of the flow stands for a coefficient in the diffusion-convection equation set in the thin structure. An asymptotic expansion of solution is constructed. This expansion is used further for justification of an asymptotic domain decomposition strategy essentially reducing the memory and the time of the code. A numerical solution obtained by this strategy is compared to the numerical solution obtained by a direct FEM computation.
Recent progress in the symmetric generation of groups

Many groups possess highly symmetric generating sets that are naturally endowed with an underlying combinatorial struc- ture. Such generating sets can prove to be extremely useful both theoretically in providing new existence proofs for groups and prac- tically by providing succinct means of representing group elements. We give a survey of results obtained in the study of these symmet- ric generating sets. In keeping with earlier surveys on this matter, we emphasize the sporadic simple groups. ADDENDUM: This is an updated version of a survey article orig- inally accepted for inclusion in the proceedings of the 2009 'Groups St Andrews' conference (27). Since (27) was accepted the author has become aware of other recent work in the subject that we incorporate to provide an updated version here (the most notable addition being the contents of Section 3.4).
Design of Efficient Construction Process Interlock Cost Estimation and Project Management in Bridge Construction

In this study, we proposed the efficient DB construction process to interlock cost estimation and process management in bridge construction. In the proposed system, construction process is divided into five hierarchical levels that are milestone network & cost analysis, skeleton network & cost analysis (sub network & cost analysis), frag network & cost analysis and cost estimating. Milestone network & cost analysis level is the highest level and cost estimating level is the lowest level. Each level is designed as DB structure so that cost calculation by level is easy and project management is efficient.
An Algorithm for Finding Positive Solutions to Polynomial Equations

We present a numerical algorithm for finding real non-negative solutions to polynomial equations. Our methods are based on the expectation maximization and iterative proportional fitting algorithms, which are used in statistics to find maximum likelihood parameters for certain classes of statistical models. Since our algorithm works by iteratively improving an approximate solution, we find approximate solutions in the cases when there are no exact solutions, such as overconstrained systems.
