Where is this? - gesture based multimodal interaction with an anthropomorphic robot

Traditional visitor guidance often suffers from the representational gap between 2D map representations and the real-world. Therefore, we propose a robotic information system that exploits its physical embodiment to present a readily interpretable interface for visitor guidance. Similar to human receptionists, it offers a familiar point of reference that can be approached by visitors and supports intuitive interaction through both speech and gesture. We focus on employing an anthropomorphic body to improve guidance functionality and interpretability of the interaction. The map, which contains knowledge about the environment, is used by robot and visitor simultaneously, with the robot translating its content into gestures. This setting affords disambiguation of information requests and thus improves robustness. It has been tested both in a laboratory demonstration setting and in our university hall, where people asked for information and thereby used the system in a natural way.
Longitudinal Analysis of Effect of Bicycle Facilities on Commute Mode Share

This paper uses census data to describe changes in bicycle commute mode shares between 1990 and 2000 in the Minneapolis-St. Paul, MN area. It specifically describes the impact of new bicycle facilities that were created during this decade. Previous efforts to understand the impact of facilities on bicycling rates have compared different locations; however, with this method it is not possible to determine the extent to which differences may have already existed before the facilities were built. This study addresses this problem by comparing the same locations before and after facilities were built, using a number of different ways of measuring facility impact. We find that the locations where facilities were built did in fact already have very high bicycle commute mode shares relative to the rest of the region; but also that these differences became even larger after the facilities were built. The areas within our facility buffers showed mode share increasing from 1.7% to 2.0%, while the remainder of the region remained constant at 0.2%. All individual facilities showed statistically significant increases in bicycle mode share. Central city trips crossing the Mississippi River showed a much larger increase than trips that did not; this reflects a number of significant improvements to bicycle accommodation on bridges during this decade. Finally, downtown Minneapolis and the University of Minnesota, where most of the facilities were concentrated, showed large increases in bicycle mode share, while downtown St. Paul, which had few improvements, had no increase.
Greening the Switch

Active research is being conducted in reducing power consumption of all the components of the Internet. To that end, we propose schemes for power reduction in network switches -- Time Window Prediction, Power Save Mode and Lightweight Alternative. These schemes are adaptive to changing traffic patterns and automatically tune their parameters to guarantee a bounded and specified increase in latency. We propose a novel architecture for buffering ingress packets using shadow ports. We test our schemes on packet traces obtained from an enterprise network, and evaluate them using realistic power models for the switches. Our simple power reduction schemes produce power savings of upto 32% with minimal increase in latency or packet-loss. With appropriate hardware support in the form of Wake-on-Packet, shadow ports and fast transitioning of the ports between its high and low power states, these savings reach 90% of the optimal algorithm's savings.
Low power branch prediction for embedded application processors

Modern embedded processors used in media and communication portable devices are now required to execute complex applications and their performance requirements are getting close to the demands of general purpose processors. The performance-per-Watt ratio is an extremely important measure in portable devices because of their limited power capacity. Branch predictors, and especially the BTB, are among the largest on-chip SRAM structures (after caches), and therefore are primary contributors to the total system power. We propose a novel micro-architectural method referred to as Shifted-Index BTB with a Set-Buffer, which reduces both dynamic and static power. Extensive simulations show that up to 80% reduction in dynamic power is achieved at the cost of up to 0.64% system slowdown. 58% reduction is static power is also achieved by applying low-leakage power techniques that mesh well with the Set-Buffer design.
SOME OBSERVATIONS ON RECENT ECONOMIC DEVELOPMENTS Address by Mr IJ Macfarlane , Governor , to the Australian Business Economists Annual Forecasting Conference

I confess that I had diffi culty in deciding on a topic for tonight’s talk. There were, in my view, no burning issues that I wanted to address, or messages that I wanted to leave my listeners with. In the event, I have decided to talk about three topics: how the world has coped with a tripling of oil prices, how the world is emerging from a period of exceptionally low interest rates, and, quite separately, is there an Australian model of macroeconomic policy?
Incremental Spectral Clustering with the Normalised Laplacian

Partitioning a graph into groups of vertices such that those within each group are more densely connected than vertices assigned to different groups, known as graph clustering, is often used to gain insight into the organization of large scale networks and for visualization purposes. Whereas a large number of dedicated techniques have been recently proposed for static graphs, the design of on-line graph clustering methods tailored for evolving networks is a challenging problem, and much less documented in the literature. Motivated by the broad variety of applications concerned, ranging from the study of biological networks to graphs of scientific references through to the exploration of communications networks such as the World Wide Web, it is the main purpose of this paper to introduce a novel, computationally efficient, approach to graph clustering in the evolutionary context. Namely, the method promoted in this article is an incremental eigenvalue solution for the spectral clustering method described by Ng. et al. (2001). Be- yond a precise description of its practical implementation and an evaluation of its complexity, its performance is illustrated through numerical experiments, based on datasets modelling the evolution of a HIV epidemic and the purchase history graph of an e-commerce website.
Influence of a “Warm Touch” Support Enhancement Intervention Among Married Couples on Ambulatory Blood Pressure, Oxytocin, Alpha Amylase, and Cortisol

Objective: To investigate whether a support intervention (warm touch enhancement) influences physiological stress systems that are linked to important health outcomes. Growing evidence points to a protective effect of social and emotional support on both morbidity and mortality. Methods: In this study, 34 healthy married couples (n = 68), aged 20 to 39 years (mean = 25.2 years), were randomly assigned to a “behavior monitoring” control group or participated in a 4-week intervention study in which clinic levels of plasma oxytocin, 24-hour ambulatory blood pressure, and salivary cortisol and alpha amylase were obtained pre and post intervention, at the same time salivary oxytocin was taken at home during weeks 1 and 4. Results: Salivary oxytocin was enhanced both early and late in the intervention group and alpha amylase was reduced at post treatment in intervention group husbands and wives relative to controls. Husbands in the intervention group had significantly lower post treatment 24-hour systolic blood pressure than the control group. Conclusion: Increasing warm touch among couples has a beneficial influence on multiple stress-sensitive systems. BP = blood pressure; ABP = ambulatory blood pressure; SBP = systolic blood pressure; DBP = diastolic blood pressure; OT = oxytocin; HPA = hypothalamic-pituitary adrenocortical; SNS = sympathetic nervous system; AUC = area under the curve.

Distillability and positivity of partial transposes in general quantum field systems

Criteria for distillability, and the property of having a positive partial transpose, are introduced for states of general bipartite quantum systems. The framework is sufficiently general to include systems with an infinite number of degrees of freedom, including quantum fields. We show that a large number of states in relativistic quantum field theory, including the vacuum state and thermal equilibrium states, are distillable over subsystems separated by arbitrary spacelike distances. These results apply to any quantum field model. It will also be shown that these results can be generalized to quantum fields in curved spacetime, leading to the conclusion that there is a large number of quantum field states which are distillable over subsystems separated by an event horizon.
Health and Quality of Life Outcomes

Many women experience vasomotor symptoms at or around the time of menopause. Hot flushes and night sweats are considered primary menopausal symptoms that may also be associated with sleep and mood disturbances, as well as decreased cognitive function. All of these symptoms may lead to social impairment and work-related difficulties that significantly decrease overall quality of life. Hot flushes have shown a great deal of variability in their frequency and severity in women. In some women, hot flushes persist for several months; in others, they may last for more than 10 years. Traditionally vasomotor symptoms were reported to begin 5 to 10 years prior to the cessation of the final menstrual cycle, corresponding with the initial decline in circulating gonadal hormones; however, night sweats in particular most often begin in perimenopause. The pathogenesis of hot flushes has not yet been fully elucidated, but the circuitry involving estrogen and neurotransmitters, norepinephrine and serotonin specifically, are hypothesized to play a major role in the altered homeostatic thermoregulatory mechanisms underlying these events. Menopause-associated vasomotor symptoms are associated with significant direct and indirect costs. Overall costs of traditional pharmacotherapy or complementary and alternative medicine modalities, including over-the-counter treatments and dietary supplements, for managing menopause-related vasomotor symptoms are substantial and include initial and follow-up physician visits and telephone calls. Additional costs include laboratory testing, management of adverse events, loss of productivity at work, and personal and miscellaneous costs. Pharmacoeconomic analyses, including those that consider risks identified by the Women's Health Initiative, generally support the cost-effectiveness of hormonal therapy for menopause-associated vasomotor symptoms, which have been the mainstay for the management of these symptoms for more than 50 years. However, because many women now want to avoid hormone therapy, there is a need for additional targeted therapies, validated by results from controlled clinical trials that are safe, efficacious, cost-effective, and well tolerated by symptomatic menopausal women. Review Menopause is characterized by physiologic and psychosocial changes in a woman's life. Menopause may be associated with vasomotor symptoms (VMS; hot flushes [also referred to as hot flashes] and night sweats), bone loss, urogenital atrophy, urinary tract infections and Published: 05 August 2005 Health and Quality of Life Outcomes 2005, 3:47 doi:10.1186/1477-7525-347 Received: 22 June 2005 Accepted: 05 August 2005 This article is available from: http://www.hqlo. com/content/3/1/47 © 2005 Utian; licensee BioMed Central Ltd.

An Investigation of the Microstructure of an Intermetallic Layer in Welding Aluminum Alloys to Steel by MIG Process

Butt joints of A5052 aluminum alloy and SS400 steel, with a new type of chamfered edge, are welded by means of metal inert gas welding and ER4043 Al-Si filler metal. The microhardness and microstructure of the joint are investigated. An intermetallic layer is found on the surface of the welding seam and SS400 steel sheet. The hardness of the intermetallic layer is examined using the Vickers hardness test. The average hardness values at the Intermetallic (IMC) layer zone and without the IMC layer zone were higher than that of the welding wire ER4043. The tensile strength test showed a fracture at the intermetallic layer when the tensile strength is 225.9 MPa. The tensile value test indicated the average of welds was equivalent to the 85% tensile strength of the A5052 aluminum alloy. The thickness of the intermetallic layers is non-uniform at different positions with the ranges from 1.95 to 5 μm. The quality of the butt joint is better if the intermetallic layer is minimized. The Si crystals which appeared at the welding seam, indicating that this element participated actively during the welding process, also contributed to the IMC layer’s formation.
U-Commerce and Trust in Digital Ecosystems

Trust and the trustworthiness of participants in on-line commerce are critical to successful transactions. U-commerce is an extension to e-commerce that offers the possibility of a richer data environment in which to assess trust. This paper contrasts e-commerce and u-commerce from the perspective of trust and considers the possible role of case-based reasoning in learning trust.
An evaluation of alternate remote sensing products for forest inventory, monitoring, and mapping of Douglas-fir forests in western Oregon

This research evaluates the utility of several remote sensing data types for the purpose of mapping forest structure and related attributes at a regional scale. Several sensors were evaluated, including (i) single date Landsat Thematic Mapper (TM); (ii) multitemporal Landsat TM; (iii) Airborne Data Acquisition and Registration (ADAR), a sensor with high spatial resolution; (iv) Airborne Visible-Infrared Imaging Spectrometer (AVIRIS), a sensor with high spectral resolution; and (v) Scanning Lidar Imager Of Canopies By Echo Recovery (SLICER), a lidar sensor that directly measures the height and canopy structure of forest vegetation. To evaluate the ability of each of the sensors to predict stand structure attributes, we assembled a data set consisting of 92 field plots within the Willamette National Forest in the vicinity of the H.J. Andrews Experimental Forest. Stand structure attributes included age, basal area, aboveground biomass, mean diameter at breast height (DBH) of dominant and codominant stems, me.
Note on the boundary terms in AdS / CFT correspondence for Rarita-Schwinger field

In this letter the boundary problem for massless and massive Rarita–Schwinger fields in the AdS/CFT correspondence is considered. The considerations are along the lines of a paper by Henneaux24 and are based on the requirement that the solutions have to be a stationary point for the action functional. It is shown that this requirement, along with a definite asymptotic behavior of the solutions, fixes the boundary term that must be added to the initial Rarita–Schwinger action. It is also shown that the boundary term reproduce the known two-point correlation functions of certain local operators in CFT living on the boundary.
The Similarities and Differences between four Leadership Models and How They Might Address Contemporary Leadership Issues and

The leadership theories presented in this research are representative of four different eras. The Trait era which began in the early 19th century correspond to the early period as delineated by Wren (2005), the theory of Bureaucracy advanced by Max Weber (1864-1920) and representative of the scientific management era, the theory of Mary Parker Follett (1886-1933), which arises out of what Wren (2005) referred to as “the social person era” and the theory of Renesis Likert (1903-1981) which underscores the modern era. These four perspectives provide the basis for a comprehensive review of leadership theories within the context of their similarities and differences and a concluding discussion on how they might address contemporary leadership issues and challenges. This paper is not an attempt to discuss the four theories from a historical perspective; rather it purposes to give some thoughts for reflection on how theories of leadership influence practices in today’s organizations.
Overexpression of Glutathione Peroxidase Prevents Left Ventricular Remodeling and Failure After Myocardial Infarction in Mice

Background—Oxidative stress plays an important role in the pathophysiology of heart failure. We determined whether the overexpression of glutathione peroxidase (GSHPx) could attenuate left ventricular (LV) remodeling and failure after myocardial infarction (MI). Methods and Results—We created MI in 12- to 16-week-old, male GSHPx transgenic mice (TG+MI) and nontransgenic wild-type littermates (WT+MI) by ligating the left coronary artery. GSHPx activity was increased in the hearts of TG mice, with no significant changes in other antioxidant enzymes. LV concentrations of thiobarbituric acid–reactive substances measured in TG+MI at 4 weeks were significantly lower than those in WT+MI. The survival rate during 4 weeks of MI was significantly higher in TG+MI than in WT+MI, although the infarct size was comparable. LV cavity dilatation and dysfunction were significantly attenuated in TG+MI. LV end-diastolic pressure was increased in WT+MI and reduced in TG+MI. Improvement of LV function in TG+MI was accompanied by a decrease in myocyte hypertrophy, apoptosis, and interstitial fibrosis in the noninfarcted LV. Myocardial matrix metalloproteinase-9 zymographic and protein levels were increased in WT+MI after 3 days but were attenuated in TG+MI. Conclusions—Overexpression of GSHPx inhibited LV remodeling and failure after MI. Therapies designed to interfere with oxidative stress might be beneficial to prevent cardiac failure.
Global Exponential Synchronization of Multiple Memristive Neural Networks With Time Delay via Nonlinear Coupling

This paper presents theoretical results on the global exponential synchronization of multiple memristive neural networks with time delays. A novel coupling scheme is introduced, in a general topological structure described by a directed or undirected graph, with a linear diffusive term and discontinuous sign term. Several criteria are derived based on the Lyapunov stability theory to ascertain the global exponential stability of synchronization manifold in the coupling scheme. Simulation results for several examples are given to substantiate the effectiveness of the theoretical results.

On the Afterglow of the X-Ray Flash of 2003 July 23: Photometric Evidence for an Off-Axis Gamma-Ray Burst with an Associated Supernova?

We present optical and near-infrared follow-up observations of the X-ray flash (XRF) of 2003 July 23. Our observations in the R band cover the temporal range from 4.2 hr to 64 days after the high-energy event. We also present the results of multicolor imaging extending to the K band on three epochs. The light curve of the R-band afterglow the first week after the burst is similar to the light curve for long-duration gamma-ray bursts (GRBs), i.e., a broken power law with a late time slope of α ≈ 2.0 (Fν ∝ t-α). Furthermore, the spectral energy distribution (SED) has a power-law (Fν ∝ ν-β) shape with slope β ≈ 1.0. However, the decay slope at t < 1 day is shallow, consistent with zero. This is in qualitative agreement with the prediction that XRFs are off-axis classical GRBs. After the first week there is a strong bump in the light curve, which peaks at around 16 days. The SED after the peak becomes significantly redder. We discuss the possible interpretations of this bump and conclude that an underlying supernova is the most likely explanation since no other model appears consistent with the evolution of the SED. Finally, we present deep spectroscopy of the burst both in the afterglow and in the bump phase. A firm upper limit of z = 2.3 is placed on the redshift of XRF 030723 from the lack of Lyα forest lines in the spectrum of the afterglow. The lack of significant absorption and emission lines in either of the two spectra excludes a spectroscopic redshift determination.
Moon search algorithms for NASA's Dawn Mission to asteroid Vesta

A moon or natural satellite is a celestial body that orbits a planetary body such as a planet, dwarf planet, or an asteroid. Scientists seek understanding the origin and evolution of our solar system by studying moons of these bodies. Additionally, searches for satellites of planetary bodies can be important to protect the safety of a spacecraft as it approaches or orbits a planetary body. If a satellite of a celestial body is found, the mass of that body can also be calculated once its orbit is determined. Ensuring the Dawn spacecraft's safety on its mission to the asteroid (4) Vesta primarily motivated the work of Dawn's Satellite Working Group (SWG) in summer of 2011. Dawn mission scientists and engineers utilized various computational tools and techniques for Vesta's satellite search. The objectives of this paper are to 1) introduce the natural satellite search problem, 2) present the computational challenges, approaches, and tools used when addressing this problem, and 3) describe applications of various image processing and computational algorithms for performing satellite searches to the electronic imaging and computer science community. Furthermore, we hope that this communication would enable Dawn mission scientists to improve their satellite search algorithms and tools and be better prepared for performing the same investigation in 2015, when the spacecraft is scheduled to approach and orbit the dwarf planet (1) Ceres.
