Analysis of Angle of Attack for Efficient Slope Ascent by Rovers Hiroaki Inotsume

What direction should a rover drive to efficiently ascend slop e f loose soil? To explore the lunar poles, rovers will need to traverse crat ers where high slip will hamper progress. Because of limited energy, rovers need to fin d ef cient routes to traverse such sloped terrain. It is an open question whether fficient and successful slope-ascending is achieved in loose soil by driving direct ly uphill or in a diagonal cross-slope direction. In this thesis, the influence of the rover’s angle of attack on slope-ascent performance was analyzed based on a slope-ascent rover model th at consists of force equilibrium conditions and terramechanics-based wheel–s oil interaction. The terramechanic model was validated in single-wheel experiment s. Rover slip, uphill velocity, and power efficiency were predicted and associated w ith the angle of attack. Analysis shows the ascent in the direct uphill direction res ults in most effective motion, in terms of velocity and power efficiency, on most of the slopes analyzed even if the vehicle longitudinal slip can be reduced by decreasin g the angle of attack. The analysis also indicates that a rover can diagonally ascend s t ep lopes where it can not drive directly up if the rover can generate sufficient lat er l grip against downhill slides. Slope-ascent experiments using a rover were conducted to ex perimentally evaluate the effect of the angle of attack. The test results valid ated the model-based analysis and the usefulness of the proposed slope-ascent mo del. A strategy to select slope-ascending routes is proposed bas ed on the model and experiment based analysis. The utility of the route selecti on method was demonstrated in simulations on various slopes and for different r ove s. The findings in this research are useful to develop path plann ing strategies and also to develop locomotion configuration and controls which can have high slopeascent capability.
EMMPRIN/CD147 is a novel coreceptor of VEGFR-2 mediating its activation by VEGF

EMMPRIN/CD147 is mainly known for its protease inducing function but a role in promoting tumor angiogenesis has also been demonstrated. This study provides evidence that EMMPRIN is a new coreceptor for the VEGFR-2 tyrosine kinase receptor in both endothelial and tumor cells, as it directly interacts with it and regulates its activation by its VEGF ligand, signalling and functional consequences both in vitro and in vivo. Computational docking analyses and mutagenesis studies identified a molecular binding site in the extracellular domain of EMMPRIN located close to the cell membrane and containing the amino acids 195/199. EMMPRIN is overexpressed in cancer and hence is able to further potentiate VEGFR-2 activation, suggesting that a combinatory therapy of an antiangiogenic drug together with an inhibitor of EMMPRIN/VEGFR-2 interaction may have a greater impact on inhibiting angiogenesis and malignancy.
Negotiator Satisfaction in Face-to-Face and Electronically Mediated Negotiations

Development and availability of modern communication technology has changed communication in negotiation fundamentally – different media can today be used for similar negotiation tasks. The process of negotiator satisfaction formation has not been studied in different media settings yet. Hence in this paper, we examine the role that communication medium (EM, FTF) plays in the development of negotiator satisfaction. Negotiator satisfaction is conceptualized as a negotiator’s socio-emotional evaluation of the negotiation outcome and process immediately after conclusion of the negotiation. Using data from an experimental roleplay simulation we can show that the communication medium’s influence on negotiator satisfaction is mediated by behavioral process variables and economic perceptions. In general, we find higher negotiator satisfaction in EM negotiations and explain this finding with lower aspirations in EM negotiations while individual negotiator profits are similar across conditions. Differences in negotiation behavior across media, namely positive relational messages and contentious behavior also account for differences in negotiator satisfaction. Interestingly, only the latter two relationships are also moderated by communication medium.
Collaborative practice-oriented business processes Creating a new case for business process management and CSCW synergy

In very recent times, organisations have started to shift their focus from highly standardised operational business processes (BPs) to other types of processes that cannot be easily replicated due to the knowledge, skills and creativity of people involved. Consequently the field of business process management (BPM) has gradually evolved to include four different, but equally important components: strategy, people, processes and technology. The renewed interest in process-related knowledge and collaboration has opened a new case for possible synergy of BPM and CSCW (computer supported cooperative work) fields. The paper argues that the key to this synergy is in the field of knowledge management. The paper introduces the knowledge dimension of BPs and uses it to determine how collaborative processes, in particular practice-oriented creative BPs, differ from other types of organizational processes. The paper argues that in the case of these BPs, process support needs to co-evolve with process execution itself, and therefore could be also considered as an ever evolving, ldquoorganicrdquo system, creating a new set of interesting research and practical challenges in the future.

Bilingualismus: eine Herausforderung für das sich entwickelnde Gehirn

Zusammenfassung Der Einsatz neurophysiologischer Methoden in der Bilingualismus-Forschung zeigte – entgegen ursprünglicher Annahmen –, dass bilinguale SprecherInnen nicht notwendigerweise andere neuronale Regionen für die Sprachverarbeitung aktivieren als monolinguale SprecherInnen. Faktoren wie die Kompetenz in einer Zweitsprache (L2) und das Alter bei Beginn des L2-Erwerbs können allerdings die Repräsentation der L2 im „bilingualen Gehirn“ beeinflussen. So wurde ein späterer Erwerbsbeginn, verglichen mit einem frühen Start in die Zweisprachigkeit, vielfach mit einer geringeren L2-Kompetenz und mit differierenden neurophysiologischen Aktivierungsmustern für sprachbezogene Aufgaben in Verbindung gebracht. Die bilinguale Forschung mit engem Bezug zu neurowissenschaftlichen Disziplinen konzentrierte sich diesbezüglich bis dato jedoch weitgehend auf sprachliche Fähigkeiten im Erwachsenenalter und beschäftigte sich erst in ihrer jüngsten Entwicklung zunehmend mit dem Erwerbsverlauf sprachlicher Fähigkeiten. Die Ergebnisse unserer Langzeitbeobachtung an 3 bilingualen Kindern, die alle gleich lange und unter vergleichbaren Umständen ihre Zweitsprache lernten, deuten auf einen Zusammenhang zwischen dem Alter zu Beginn des Erwerbs und den grammatikalischen Fähigkeiten in der L2 hin; Wortschatz und Lesefähigkeit scheinen hingegen nicht mit dem Alter bei Erwerbsbeginn zusammenzuhängen. Weiters reagierte das L2-Sprachsystem des ältesten Kindes am stabilsten auf eine vorübergehende Veränderung der sprachlichen Umgebung. Um jedoch generalisierte Aussagen über linguo-kognitive Entwicklungsverläufe bei Kindern und Jugendlichen, die gleichzeitig mehrere Sprachen erlernen, treffen zu können, bedarf es weiterer interdisziplinärer Forschungsbestrebungen zum sich entwickelnden „multilingualen Gehirn“.
HILL: A Hybrid Indoor Localization Scheme

Localization is a fundamental operation in wireless networks. Location determination is normally accomplished using the Global Positioning System (GPS) for outdoor applications. For indoor localization, GPS does not work due to the lack of the line of sight to satellites. High-precision indoor localization is critical to many personal and business applications. WiFi-based indoor localization was proposed to be a practical method to locate WiFi-enabled devices due to the popularity of WiFi networks. However, it suffers from large localization errors. Our experimental results indicate that this scheme consistently leads to an average error around 3 meters. The existence of different locations with similar WiFi signal strength is the reason behind the large errors. To improve the localization precision, a hybrid indoor localization scheme, HILL, is proposed in this paper. Inspired by the fact that a large number of WiFi-enabled mobile devices have been deployed, HILL uses 3 phases to improve the precision of WiFi-based localization. First of all, it measures the distances between each pair of peer devices through acoustic ranging. Secondly, the Classical Metric Multidimensional Scaling (MDS) method is applied to the collected distances, which results in a graph consistent with the distances. Finally, the graph generated by MDS is embedded onto the graph corresponding to WiFi-based localization in order to achieve high localization precision. Our experimental results indicate that the average localization error of HILL is about 1 meter.
A cautionary tale of two matrices: the duality of multivariate abstraction

The metaphorical Tale of Two Matrices reveals how combining the worlds of multivariate abstraction and empiricism can both illuminate and obfuscate biological questions. To be sure, there are many potential benefits to limiting the dimensionality in multivariate problems—greater statistical power and the ability to explore relationships among more than two traits simultaneously are chief among them. Conversely, the rotation of trait space into new orthogonal axes may lead us ever further from the biological realities and intuitions that underlie the questions we pursue. The seduction of generating increasingly complex ways to view selection and multivariate inheritance brings with it the cost of greater and greater abstraction as disparate biological forces are lumped into common summary statistics. The success of matrix diagonalization for examining selection and quantitative genetics will be determined by practitioners’ ability to keep their eyes on the prize and use the techniques to inform experimental tests of the hypotheses they generate. The power of any methodology is determined by its ability to help us answer the questions we want to ask. Evolutionary quantitative genetics (EQG) and related approaches became popular because they are quantitative and simple to apply, and because they offer a direct insight into fundamental questions in evolutionary biology. As is often the case with a new set of tools, the heyday of EQG was accompanied by a sometimes blind application to any and every system, without sufficient regard to the importance of conceptual context and the limitations of the techniques. Diagonalization of the important matrices in EQG gives us a new set of variables to examine, but we are still inherently bound by the same questions, constraints and pitfalls. Below, we offer our opinions on the key problems in selection and EQG and the ways in which matrix diagonalization may or may not move us forward on these fronts. What is the form of natural selection?
A SCUBA-2 survey of FeLoBAL QSOs. Are FeLoBALs in a `transition phase' between ULIRGs and QSOs?

It is thought that a class of broad absorption line (BAL) QSOs, characterized by Fe absorption features in their UV spectra (called `FeLoBALs'), could mark a transition stage between the end of an obscured starburst event and a youthful QSO beginning to shed its dust cocoon, where Fe has been injected into the interstellar medium by the starburst. To test this hypothesis, we have undertaken deep Submillimetre Common-User Bolometer Array 2 (SCUBA-2) 850 μm observations of a sample of 17 FeLoBAL QSOs with 0.89 ≤ z ≤ 2.78 and -23.31 ≤ MB ≤ -28.50 to directly detect an excess in the thermal emission of the dust which would probe enhanced star formation activity. We find that FeLoBALs are not luminous sources in the sub-mm, none of them are individually detected at 850 μm, nor as a population through stacking (Fs = 1.14 ± 0.58 mJy). Statistical and survival analyses reveal that FeLoBALs have sub-mm properties consistent with BAL and non-BAL QSOs with matched redshifts and magnitudes. An Spectral Energy Distribution fitting analysis shows that the far-infrared emission is dominated by active galactic nuclei activity, and a starburst component is required only in 6/17 sources of our sample; moreover the integrated total luminosity of 16/17 sources is L ≥ 1012 L⊙, high enough to classify FeLoBALs as infrared luminous. In conclusion, we do not find any evidence in support of FeLoBAL QSOs being a transition population between an ultraluminous infrared galaxy (ULIRG) and an unobscured QSO; in particular, FeLoBALs are not characterized by a cold starburst which would support this hypothesis.
A Scalable , Reconfigurable , and Efficient Data Center Power Distribution Architecture

Significant improvements in efficiency, power density, power monitoring, and reconfigurability have been achieved in data center power distribution. The past techniques of massive transformer-based power distribution units feeding under-floor hardwired circuits via rigid or flexible conduit are shown to be obsolete. This paper explains some the newer approaches to power distribution including modular power distribution and overhead power busway, and shows their advantages when compared to the legacy approach.
Serotonin and serotonin transporter gene variant in rotating shift workers.

STUDY OBJECTIVES Because serotonin (5-HT) is a neurotransmitter associated with circadian rhythm regulation, we explored a possible relation among 5-HT, serotonin metabolite, 5-hydroxyindolacetic acid (5HIAA), and the functional polymorphism of the serotonin transporter gene (SLC6A4) promoter with rotating shift work. DESIGN AND PARTICIPANTS 683 men were included in this study: 437 day workers were compared with 246 rotating shift workers. RESULTS Platelet 5-HT content differed significantly (P = 0.002) between day workers (41.28+/-1.99 pg/mg) and rotating shift workers (37.91+/-4.16 pg/mg); 5-HIAA content was also significantly (P = 0.00004) higher in day workers (11.40+/-0.82 pg/mg) than in rotating shift workers (9.33+/-1.02 pg/ mg). We looked for further differences in SLC6A4 promoter (5-HTTLPR, 44 bp insertion: long (L)/deletion: short (S) alleles). We found a significant (P = 0.016) difference in genotype distribution between day workers LL: 126 (28.8%), LS: 202 (46.2%), and SS: 109 (24.9%), and rotating shift workers LL: 47 (19.1%), LS: 124 (50.4%), and SS: 75 (30.5%). When we divided the subjects between workers with less and more than 60 month rotating shift-work exposure, the difference in SLC6A4 genotypes frequency was only significant in the group with > or =60 months (P = 0.011). In addition, there was a significantly lower content of platelet 5-HIAA in S allele carriers in comparison with the other genotypes (SS: 9.2+/-1.0 pg/mg vs. SL/LL: 11.0+/-0.8 pg/mg, P <0.02). CONCLUSIONS Platelet 5-HT and 5-HIAA contents were significantly lower in rotating shift workers than day workers, and there was a significant association between the S variant of SLC6A4 promoter and shift work. These findings may be important for targeting effective therapeutic strategies to ameliorate the associated comorbidities and behavioral problems in rotating shift workers.
Editorial - On the Intellectual Structure and Evolution of ISR

Scholars within fields frequently introspect about the evolution of their research disciplines, asking if the discipline is developing a cumulative research tradition, influencing scholarly work in other fields, and expanding its boundaries. In this spirit, I examine the intellectual structure and evolution of one disciplinary journal, ISR, over the most recent four-year period (2012–2015). I use a census of citation data and classify journals citing ISR and cited by ISR into the disciplines they represent. Analyzing 12,833 citations to ISR from 100 journals, and 7,731 citations from ISR to papers published in 67 journals I find that, consistent with prior studies, ISR reflects the multidisciplinarity of the information systems (IS) discipline, its boundaries are expanding to include new disciplines, and the journal draws extensively on other IS journals. I raise some questions for further introspection about the impact and visibility of IS research.
Large deviation analysis of the CPD detection problem based on random tensor theory

The performance in terms of minimal Bayes' error probability for detection of a random tensor is a fundamental understudied difficult problem. In this work, we assume that we observe under the alternative hypothesis a noisy rank-ñ tensor admitting a Q-order Canonical Polyadic Decomposition (CPD) with large factors of size Nq × R, i.e., for 1 ≤ q ≤ Q, R,Nq → ∞ with R1/q/Nq converges to a finite constant. The detection of the random entries of the core tensor is hard to study since an analytic expression of the error probability is not easily tractable. To mitigate this technical difficulty, the Chernoff Upper Bound (CUB) and the error exponent on the error probability are derived and studied for the considered tensor-based detection problem. These two quantities are relied to a key quantity for the considered detection problem due to its strong link with the moment generating function of the log-likelihood test. However, the tightest CUB is reached for the value, denoted by s∗, which minimizes the error exponent. To solve this step, two methodologies are standard in the literature. The first one is based on the use of a costly numerical optimization algorithm. An alternative strategy is to consider the Bhattacharyya Upper Bound (BUB) for s∗ = 1/2. In this last scenario, the costly numerical optimization step is avoided but no guaranty exists on the optimality of the BUB. Based on powerful random matrix theory tools, a simple analytical expression of s∗ is provided with respect to the Signal to Noise Ratio (SNR) and for low rank CPD. Associated to a compact expression of the CUB, an easily tractable expression of the tightest CUB and the error exponent are provided and analyzed. A main conclusion of this work is that the BUB is the tightest bound at low SNRs. At contrary, this property is no longer true for higher SNRs.
Irritability During the Month of Ramadan

Objectives: We hypothesized that people in Morocco are more irritable during the month of Ramadan than during the rest of the year. Our objectives were to measure irritability in fasting Muslims during the month of Ramadan, to describe its various modes of expression, and to examine risk factors for this irritability. Methods and Subjects: We studied 100 healthy volunteers during the month of Ramadan for two successive years (1994 and 1995). All subjects were male (mean age, 32 ± 5.8 years), and 51% of them were smokers. Irritability was assessed over a 6-week period (before, four times during, and after the end of Ramadan). We assessed both subjective (visual analog scale) and objective irritability. We also recorded the consumption of psychostimulants, duration of sleep, and anxiety level as measured by the Hamilton Anxiety Scale. Results: Irritability was significantly higher in smokers than in nonsmokers before the beginning of Ramadan. It was higher in both groups during the Ramadan month. Irritability increased continuously during Ramadan and reached its peak at the end of the month. Consumption of psychostimulants (coffee and tea) and anxiety level followed the same pattern. Smokers and nonsmokers had a similar pattern of irritability over time, but irritability increased more in smokers than in nonsmokers.
Annotation Scheme and Gold Standard for Dutch Subjective Adjectives

Many techniques are developed to derive automatically lexical resources for opinion mining. In this paper we present a gold standard for Dutch adjectives developed for the evaluation of these techniques. In the first part of the paper we introduce our annotation guidelines. They are based upon guidelines recently developed for English which annotate subjectivity and polarity at word sense level. In addition to subjectivity and polarity we propose a third annotation category: that of the attitude holder. The identity of the attitude holder is partly implied by the word itself and may provide useful information for opinion mining systems. In the second part of paper we present the criteria adopted for the selection of items which should be included in this gold standard. Our design is aimed at an equal representation of all dimensions of the lexicon , like frequency and polysemy, in order to create a gold standard which can be used not only for benchmarking purposes but also may help to improve in a systematic way, the methods which derive the word lists. Finally we present the results of the annotation task including annotator agreement rates and disagreement analysis.
Critical Role of the Human ATP-Binding Cassette G1 Transporter in Cardiometabolic Diseases

ATP-binding cassette G1 (ABCG1) is a member of the large family of ABC transporters which are involved in the active transport of many amphiphilic and lipophilic molecules including lipids, drugs or endogenous metabolites. It is now well established that ABCG1 promotes the export of lipids, including cholesterol, phospholipids, sphingomyelin and oxysterols, and plays a key role in the maintenance of tissue lipid homeostasis. Although ABCG1 was initially proposed to mediate cholesterol efflux from macrophages and then to protect against atherosclerosis and cardiovascular diseases (CVD), it becomes now clear that ABCG1 exerts a larger spectrum of actions which are of major importance in cardiometabolic diseases (CMD). Beyond a role in cellular lipid homeostasis, ABCG1 equally participates to glucose and lipid metabolism by controlling the secretion and activity of insulin and lipoprotein lipase. Moreover, there is now a growing body of evidence suggesting that modulation of ABCG1 expression might contribute to the development of diabetes and obesity, which are major risk factors of CVD. In order to provide the current understanding of the action of ABCG1 in CMD, we here reviewed major findings obtained from studies in mice together with data from the genetic and epigenetic analysis of ABCG1 in the context of CMD.
