Form and function in experimental design

Standard practices in experimental economics arise for different reasons. The “no deception” rule comes from a cost-benefit tradeoff; other practices have to do with the uses to which economists put experiments. Because experiments are part of scientific conversations that mostly go on within disciplines, differences in standard practices between disciplines are likely to persist.
Low complexity multi-criteria ranking based greedy algorithm for dynamic PRB allocation in 4G systems

A computationally efficient multi-criteria ranking based greedy (MCRG) algorithm is proposed for physical resource block (PRB) allocation in the fourth generation (4G) systems, where the users' utilities are ranked with multiple criteria, to enhance the performance of the basic greedy algorithm. The MCRG algorithm not only outperforms the previous single criterion ranking based greedy algorithm in terms of throughput and outage probability, but also provides a near optimal performance, irrespective of the optimisation utility employed. In particular, when the MCRG algorithm is used to optimise the channel frequency response (CFR) utility, the overall computational complexity is kept at a very low level, without sacrificing the performance.
Standard fixpoint iteration for Java bytecode verification

Java bytecode verification forms the basis for Java-based Internet security and needs a rigorous description. One important aspect of bytecode verification is to check if a Java Virtual Machine (JVM) program is statically well-typed. So far, several formal specifications have been proposed to define what the static well-typedness means. This paper takes a step further and presents a chaotic fixpoint iteration, which represents a family of fixpoint computation strategies to compute a least type for each JVM program within a finite number of iteration steps. Since a transfer function in the iteration is not monotone, we choose to follow the example of a nonstandard fixpoint theorem, which requires that all transfer functions are increasing, and monotone in case the bigger element is already a fixpoint. The resulting least type is the artificial top element if and only if he JVM program is not statically well-typed. The iteration is standard and close to Sun's informal specification and most commercial bytecode verifiers.
High Prevalence of β-lactamase and Plasmid-Mediated Quinolone Resistance Genes in Extended-Spectrum Cephalosporin-Resistant Escherichia coli from Dogs in Shaanxi, China

Objective: The aim of this study was to investigate the occurrence and molecular characterization of extended-spectrum β-lactamases (ESBL), plasmid-mediated AmpC β-lactamase (pAmpC) and carbapenemases as well as plasmid-mediated quinolone-resistant (PMQR) among extended-spectrum cephalosporin-resistant (ESC-R) Escherichia coli from dogs in Shaanxi province in China. Methods: A total of 40 ESC-R Escherichia coli selected from 165 Extraintestinal pathogenic E. coli (ExPEC) isolated from dogs were screened and characterized for the genes encoding for the ESBLs, pAmpC, carbapenemases and PMQR genes by PCR and sequencing. Phylogenetic groups, virulence gene profiles and multilocus sequence typing (MLST) were used to investigate the genetic background of the ESC-R E. coli isolates. Results: Among 40 ESC-R E. coli, the predominant β-lactamase gene was blaCTX−Ms (n = 35), and followed by blaTEM−1 (n = 31), blaSHV−12 (n = 14), blaOXA−48 (n = 8), blaTEM−30 (n = 4), blaCMY−2 (n = 3) and blaDHA−1 (n = 2). The most common specific blaCTX−M gene subtype was blaCTX−M−15 (n = 31), and followed by blaCTX−M−123 (n = 14), blaCTX−M−1 (n = 10), blaCTX−M−14 (n = 10) and blaCTX−M−9 (n = 7). PMQR genes were detected in 32 (80%) isolates, and the predominant PMQR gene was aac(6′)-Ib-cr (n = 26), followed by qnrS (n = 12), qnrD (n = 9), qnrB (n = 8), qepA (n = 4), and all PMQR genes were detected in co-existence with β-lactamase genes. traT (n = 34) and fimH (n = 32) were the most prevalent virulence genes, and virulence genes fimH, iutA, fyuA, malX, iha, and sat were more prevalent in phylogenetic group B2. The 40 ESC-R isolates analyzed were assigned to 22 sequence types (STs), and the clonal lineages ST131 (n = 10) and ST10 (n = 9) were the predominant STs. Conclusion: High prevalence of β-lantamases and PMQR genes were detected among ESC-R E. coli from companion animals. This is also the first description of the co-existence of six β-lantamase genes and five PMQR genes in one E. coli isolate. Moreover, 10 ST131 clones harboring CTX-M-15 were detected.
Algorithmic testing for QT interval measurement

The PTB diagnostic ECG database has been used for testing the fully automated program for the identification and measurement of QT interval. The database consists of 549 ECG recordings of 294 subjects. The testing algorithm uses the Padova program, which identifies all QRS complexes analyzing a global spatial velocity and the ECG signal. Different strategies for the choice of the optimal QT interval have been compared, and the optimization of T end in the single leads was performed using the well annotated CSE database. This paper indicates that the more reliable and accurate estimates of the QT interval is the median value of all the measurements from the analysis of the 12 ECG leads (QT global). In addition, the Challenge and the public PTB database reveal their potentiality for the improvement of ECG classifiers and in particular of QT estimators. However, for clinical evaluation it is necessary to have a more consistent "gold standard".
Small molecule-induced oxidation of protein disulfide isomerase is neuroprotective

Significance Protein disulfide isomerase (PDI) is a chaperone protein in the endoplasmic reticulum. It is up-regulated in mouse models of, and brains of patients with, neurological protein folding diseases. Irreversible inhibition of PDI activity by the small molecule 16F16 results in protection in cell and organotypic brain slice culture models of Huntington disease. Here, we identified lead optimized compound (LOC)14 as a nanomolar, reversible inhibitor of PDI that protects PC12 cells and medium spiny neurons from the toxic mutant huntingtin protein. LOC14 has improved potency compared with 16F16 and displays favorable pharmaceutical properties, making it a suitable compound to evaluate the therapeutic potential of inhibiting PDI in multiple disease models. Protein disulfide isomerase (PDI) is a chaperone protein in the endoplasmic reticulum that is up-regulated in mouse models of, and brains of patients with, neurodegenerative diseases involving protein misfolding. PDI’s role in these diseases, however, is not fully understood. Here, we report the discovery of a reversible, neuroprotective lead optimized compound (LOC)14, that acts as a modulator of PDI. LOC14 was identified using a high-throughput screen of ∼10,000 lead-optimized compounds for potent rescue of viability of PC12 cells expressing mutant huntingtin protein, followed by an evaluation of compounds on PDI reductase activity in an in vitro screen. Isothermal titration calorimetry and fluorescence experiments revealed that binding to PDI was reversible with a Kd of 62 nM, suggesting LOC14 to be the most potent PDI inhibitor reported to date. Using 2D heteronuclear single quantum correlation NMR experiments, we were able to map the binding site of LOC14 as being adjacent to the active site and to observe that binding of LOC14 forces PDI to adopt an oxidized conformation. Furthermore, we found that LOC14-induced oxidation of PDI has a neuroprotective effect not only in cell culture, but also in corticostriatal brain slice cultures. LOC14 exhibited high stability in mouse liver microsomes and blood plasma, low intrinsic microsome clearance, and low plasma-protein binding. These results suggest that LOC14 is a promising lead compound to evaluate the potential therapeutic effects of modulating PDI in animal models of disease.
IRELAND ’ S TRADING POTENTIAL WITH CEECS 161 II PATTERNS OF TRADE BETWEEN THE EU AND THE CEECs 2

*We are grateful to Dermot McAleese and to two anonymous referees for helpful comments. Lars Nilsson generously supplied distance data. Abstract: Using a gravity model, we estimate the magnitude of potential trade flows between Ireland and the five CEEC countries which are currently negotiating accession to the EU. We find that Irish exports were already close to their " normal " level in 1994, but that imports from the CEECs were still less than half of their potential size. The value of estimated potential trade corresponds to 0.8 per cent of Irish GNP. The actual share in 1994 was 0.5 per cent. EU enlargement would raise Ireland-CEEC trade to 1.2 per cent of GNP. The short-term scope for trade expansion therefore appears to be modest. Stronger potential for trade growth emerges in the " long-term " scenario, which assumes partial income convergence of the EU and the CEECs. According to our upper-limit estimate in the convergence scenario, the value of Irish trade with the CEECs could reach 8.3 per cent of Irish GNP in 2020. I INTRODUCTION t is all but certain that a number of Central and Eastern European countries I (CEECs) will join the European Union in the next decade. The EU opened bilateral accession negotiations with six applicant countries in April 1998, and it has declared a strategic aim to embrace an even wider circle of new members in the medium term. These impending changes will undoubtedly impact significantly on a small
Color-Mood-Aware Clothing Re-texturing

In this paper, we present a novel color-mood-aware technique to re-texture clothing in a photograph. An efficient classification algorithm is developed to classify clothing textures using color mood scheme. To re-texture the clothing, our approach first computes the gradient maps for the cloth region to be replaced and then calculates the texture distortion coordinates on the projected cloth region according to the gradient maps. After the user selects a target clothing texture from the classified clothing texture database, the lighting and shading effects on the original photograph is transferred using the HSV color space. Experimental results show that the proposed approach successfully re-textures the clothes in photographs while preserving the geometry and lighting features.
Species composition and abundance of rodents in Kafta-Sheraro National Park, Ethiopia: preliminary results

An ecological survey was conducted to assess the species composition and abundance of rodents in Kafta-Sheraro National Park, Ethiopia from June 2017 to April 2018 covering wet and dry seasons. Rodents were trapped using Sherman live traps from five selected habitat types—natural forest, bushland, grassland, farmland, and human settlement. A total of 209 individuals of rodents belonging to seven species were captured over 2940 trap nights, and three species of rodents were only observed. The trapped rodent species include Mastomys natalensis, Stenocephalemys albipes, Rattus rattus, Mastomys awashensis, Acomys cahirinus, Arvicanthis niloticus dembeensis, and Mastomys erythroleucus. Lemniscomys striatus, Hystrix cristata, and Xerus rutilus were only sighted during the study. Mastomys natalensis was the most abundant species (41.1%), followed by Stenocephalemys albipes (26.3%) and Rattus rattus (18.2%), whereas Mastomys erythroleucus (1.4%) was the least abundant species. The abundance of female (59.8%) was higher than male (40.2%). Of the total trapped rodents, 52.2% were adults, 32% sub-adult and 15.8% young. The abundance of rodents was varied among habitat types and between seasons. The results of the study revealed that the park has diverse species of fauna including rodents.
Open to Diversity: Openness to Experience Predicts Beliefs in Multiculturalism and Colorblindness Through Perspective Taking

The present research examines the influence of personality on ideologies about diversity in society. In two studies (N = 668), we test whether Openness to Experience predicts beliefs in multiculturalism and colorblindness, and whether these relationships are mediated by perspective-taking tendencies. In Study 1, Openness positively predicted multiculturalism but negatively predicted colorblindness through ethnic perspective taking – findings that were independent of empathy, age, gender, and race/ethnicity. In Study 2, we attempted to replicate and extend our findings by using different measures of multiculturalism and colorblindness and a more general, interpersonal operationalization of perspective taking. Results indicate Openness positively predicted both multiculturalism and colorblindness through interpersonal perspective taking (also independent of age, gender, and race/ethnicity), suggesting the pattern of findings varied as a function of perspective-taking type. Implications for the complexity of the Openness dimension and future research directions are discussed.
An MRF cross-layer resource allocation approach with back-pressure features for QoS in dynamic social and cognitive communications

Future dynamic wireless and online social networks will require more agile and efficient infrastructures to support the anticipated user traffic and service requirements. In response, in this work, we propose a novel spectrum-agile resource allocation approach that combines Markov Random Field (MRF) cross-layer decisions for the allocation of resources at the lower protocol layers with Back-pressure (BP) features at the higher ones, in order to achieve the above objectives. The BP-enhanced MRF (BPeMRF) network optimization serves the purpose of improving the capacity of agile infrastructures in a low complexity manner, while espousing the recent developments in dynamic spectrum environments (cognitive radios), which are required to adapt fast according to the demands of overlaying dynamic online social networks. The obtained results exhibit the efficacy of BPeMRF regarding the above objectives and demonstrate significant promise for further improving the corresponding infrastructures.
Insulin-responsive Aminopeptidase Trafficking in 3T3-L1 Adipocytes*

The insulin-responsive aminopeptidase (IRAP/VP165/gp160) was identified originally in GLUT4-containing vesicles and shown to translocate in response to insulin, much like the glucose transporter 4 (GLUT4). This study characterizes the trafficking and kinetics of IRAP in exocytosis, endocytosis, and recycling to the membrane in 3T3-L1 adipocytes. After exposure of 3T3-L1 adipocytes to insulin, IRAP translocated to the plasma membrane as assessed by either cell fractionation, surface biotinylation, or the plasma membrane sheet assay. The rate of exocytosis closely paralleled that of GLUT4. In the continuous presence of insulin, IRAP was endocytosed with a half-time of about 3–5 min. IRAP endocytosis is inhibited by cytosol acidification, a property of clathrin-mediated endocytosis, but not by the expression of a constitutively active Akt/PKB. Arrival in an LDM fraction derived via subcellular fractionation exhibited a slower time course than disappearance from the cell surface, suggesting additional endocytic intermediates. As assayed by membrane “sheets,” GLUT4 and IRAP showed similar internalization rates that are wortmannin-insensitive and occur with a half-time of roughly 5 min. IRAP remaining on the cell surface 10 min following insulin removal was both biotin- and avidin-accessible, implying the absence of thin-necked invaginations. Finally, endocytosed IRAP quickly recycled back to the plasma membrane in a wortmannin-sensitive process. These results demonstrate rapid endocytosis and recycling of IRAP in the presence of insulin and trafficking that matches GLUT4 in rate.
Parsing model for answer extraction in Chinese question answering system

This paper presents a novel approach to answer extraction in Chinese question answering (QA) system. An extended lexicalized context-free grammar parser is used for question and answer understanding, the exact answer is extracted with the clue of named entity (NE) and question classification (QC). It shows that the-performance of QA will be greatly improved with more comprehensive language understanding technologies.
The Role of IT in Customer Satisfaction in Inter-Organizational Relationships

There is an increasing use of modern information technology (IT) in nearly all parts of business life – and inter-organizational relationships are no exemption from this. However the role of IT in relationships is not really understood so far. In this paper we analyze the role of IT in relation to customer satisfaction in business-to-business relationships. We argue that the way in which a customer is treated IT-wise will influence the way the customer is satisfied with a supplier. However, IT satisfaction is assumed to be only one part of the overall satisfaction besides other satisfaction dimensions such as product and service. An empirical study of 131 supplier-customer relationships reveals that IT satisfaction is a separate dimension of the overall satisfaction. Furthermore IT satisfaction has a positive impact on perceived relationship value and trust. The degree of IT use and supplier’s IT know-how are identified as important antecedents of customer’s IT satisfaction. Overall, IT satisfaction is an important influencer of inter-organizational relationships. Managerial implications and further research questions are discussed at the end of the paper.
Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension

Aims - We analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentrations, mimicking sunspots with various representative magnetic field configurations. Methods - Numerical simulations of wave propagation through the solar sub-photosphere with a localised magnetic field concentration are carried out using SAC, which solves the MHD equations for gravitationally stratified plasma. The initial equilibrium density and pressure stratifications are derived from a standard solar model. Acoustic waves are generated by a source located at the height corresponding approximately to the visible surface of the Sun. By means of local helioseismology we analyse the response of vertical velocity at the level corresponding to the visible solar surface to changes induced by magnetic field in the interior. Results - The results of numerical simulations of acoustic wave propagation and dispersion in the solar sub-photosphere with localised magnetic field concentrations of various types are presented. Time-distance diagrams of the vertical velocity perturbation at the level corresponding to the visible solar surface show that the magnetic field perturbs and scatters acoustic waves and absorbs the acoustic power of the wave packet. For the weakly magnetised case, the effect of magnetic field is mainly thermodynamic, since the magnetic field changes the temperature stratification. However, we observe the signature of slow magnetoacoustic mode, propagating downwards, for the strong magnetic field cases.
Study on phase calibration signal processing

The traditional method for the extraction of phase calibration (PCAL) signal is inefficient when the number of PCAL tone is large. According to the special spectrum of the PCAL signal, an efficient method based on DFT is proposed for the multi-tones extraction. All the phases of the multi PCAL tones can be obtained in once DFT. The computation amount of the new method doesn't increase with the number of PCAL tones. Compared with the traditional correlation method, the new method is superior when the tone' number is larger than seven. Field experiment is conducted to verify the new method.
Construction of a Chinese-English WordNet and its application to CLIR

This paper integrates five linguistic resources, including Cilin, a Chinese-English dictionary, ASBC corpus, SemCor, and WordNet, to construct a Chinese-English WordNet. The result is employed in Chinese-English information retrieval. Under TREC-6 text collection, TREC topics 301-350, and Smart information retrieval system, the model for CLIR achieves 69.23% of monolingual information retrieval. It also gains 10.02% increase relative to a model that resolves translation ambiguity and target polysemy together using a Chinese-English dictionary.
Profit-aware Team Grouping in Social Networks: A Generalized Cover Decomposition Approach

In this paper, we investigate the profit-aware team grouping problem in social networks. We consider a setting in which people possess different skills and compatibility among these individuals is captured by a social network. Here, we assume a collection of tasks, where each task requires a specific set of skills, and yields a different profit upon completion. Active and qualified individuals may collaborate with each other in the form of \emph{teams} to accomplish a set of tasks. Our goal is to find a grouping method that maximizes the total profit of the tasks that these teams can complete. Any feasible grouping must satisfy the following three conditions: (i) each team possesses all skills required by the task, (ii) individuals within the same team are social compatible, and (iii) each individual is not overloaded. We refer to this as the \textsc{TeamGrouping} problem. Our work presents a detailed analysis of the computational complexity of the problem, and propose a LP-based approximation algorithm to tackle it and its variants. Although we focus on team grouping in this paper, our results apply to a broad range of optimization problems that can be formulated as a cover decomposition problem.
Digital Audio Information Compression Using Wavelets

The digital representation of audio data offers many advantages: high noise-immunity, stability and etc. The application of wavelet transform for audio information compression was investigated in the present research work. The developed software model allowed to find out the influence of different factors for the compression ratio. The initial audio file is compressed in 2-4 times depending on different parameters. Thus the restored file is deformed less than on 10 %
