Stellar halo hierarchical density structure identification using (F)OPTICS

Context. The stellar halo holds some of the best preserved fossils of Galactic formation history that can be detected as overdensities. The detection and analysis of merger by-products within the halo enables the reconstruction of the accretion history of the Milky Way. Upcoming large-scale all-sky surveys such as Gaia and The Large Synoptic Survey Telescope (LSST) will provide a huge and rich data set, which at the same time poses challenges for automated halo debris detection. Aims. We investigate the overdensity detection algorithm Ordering Points To Identify the Clustering Structure (OPTICS) as a method to identify tidal debris in the Galactic halo with large-scale surveys, as well as the variant F OPTICS which is capable of handling data sets with multi-dimensional uncertainty ellipsoids. Methods. We applied OPTICS to the a simulated Galactic stellar Halo to assess the detection performance. Additionally, we tested the performance of F OPTICS is tested by introducing uncertainty ellipsoids to the 6D phase space of two test cases. We present the Jaccard index as an alternative way to test the stability of halo debris overdensity detections without the need for a local background density estimate. Results. We optimized the OPTICS overdensity detection algorithm so that it has a slightly superlinear run-time complexity, making the method suitable for large-scale surveys. Our test on a mock galactic halo in 6D phase space shows an excellent capability to not only detect the compact dense clusters, but also the larger streams that cover a significant part of the sky. The output of OPTICS, the so-called 2D reachability diagram, proved to be a very useful tool to grasp the size, density, and substructure of the overdensities without needing to resort to complex projections of the 6D phase space. Using F OPTICS, we show the effects of introducing uncertainty ellipsoids in the 6D phase space on the retrieved tidal streams, and how the detectability of a cluster depends on whether its size and density is sufficiently large to overcome the effects of the uncertainties on the attributes.
Measuring Young’s modulus of 20LP10L20-LLA40 Microspheres and Gelatin-Methacrylamide (Gelma) Hydrogel using nanoindentation

Nanoindentation using AFM and nanoindeter was used to measure the Young's modulus of 20LP10L20-LLA40 Microspheres and Gelatin-Methacrylamide (Gelma). Three different analytical methods were used for calculating the Young's modulus of microspheres in order to compare the results and find the optimal analytical method. The Young's modulus of GelMA samples was calculated from force-displacement and creep curves. Oliver-Pharr's analytical method was used to calculate the modulus from force-displacement data and a curve fitting method developed by Oyen was used to calculate the modulus from creep data.
An Evaluation of Bur Oak (Quercus macrocarpa) Decline in the Urban Forest of Winnipeg, Manitoba, Canada

Winnipeg, Manitoba, Canada, has a large, indigenous population of bur oak (Quercus macrocarpa Michx.). In the 1980s, many of these trees were showing signs of decline, a disease caused by a complex of abiotic and secondary biotic stressing agents. Potential causal factors were investigated by comparing various aspects of 120 bur oaks visually rated as healthy or declined based on crown dieback levels. The results indicated that many selected bur oak trees predated surrounding urban development and that declined trees were significantly older with more severe stem wounds and competition from surrounding trees than healthy specimens. Average annual growth ring widths of healthy and declined trees were similar in the early part of the 20th century. However, decline actually began decades before symptoms were noticed, coinciding with a period of intense city-wide urban development, as growth of declined trees was slower than that of healthy trees beginning sporadically in the 1940s and consistently from 1974 to 2001. During the early years of decline, the year-by-year separation in ring width between the two categories was significantly positively related to precipitation levels. This suggested that in wet years, declined trees may have been surrounded by unfavorable water-logged soils, possibly as a result of natural drainage patterns being impeded by urban development.
Correlates of Anogenital Injuries in Adolescent Females

Objective: We sought to investigate correlates of anogenital injuries (AGIs) in adolescents. Methods: Our retrospective study included sexually assaulted female patients aged 12 to 17 reporting attempted or completed vaginal or anal penetration between 2002 and 2011. Forensic nurses performed anogenital examinations using colposcopy, digital macrovisualization, and toluidine blue dye application. We reviewed case files for AGIs and demographic and sexual assault characteristics. Results: Of the 1961 sexual assault examinations that met our inclusion criteria, 59.6% displayed AGIs. Our logistic regression model using 1752 examinations found the following variables associated with less injury: intercourse within 5 days prior to assault (OR 0.72, 95% CI = 0.55 to 0.95); post-coital interval of 49-72 (OR 0.50, 95% CI = 0.36 to 0.71), 73-96 (OR 0.41, 95% CI = 0.25 to 0.68), and 97-120 hours (OR 0.26, 95% CI = 0.13 to 0.51). Only lack of prior sexual experience was associated with increased injury (OR 2.01, 95% CI = 1.58 to 2.55). Conclusions: In our adolescent patient population, examination findings of AGIs correlate with variables related to time from assault and prior sexual experience.
Characterization of a Measurement System for Dynamic Effects in Large-Aperture SC Quadrupole Magnets

Abstract A new measurement system, based on a large-diameter search-coil rotating in the superfluid helium, a fast digital integrator, a motor drive unit with slip rings, and a flexible software environment was developed at CERN for the measurement of dynamic effects in superconducting magnets. This system has made it possible the measure, with a resolution of up to 1 Hz, the multipole field errors due to superconductor magnetization and interstrand coupling currents. In this paper we present the development and calibration of the measurement system, its installation in the vertical cryostat of CERN’s recently refurbished test station, and its application to the US-LARP built, 120-mm aperture Nb 3 Sn quadrupole magnet (HQ01e) for the upgrade of the LHC insertion regions. THE FAME MEASUREMENT SYSTEM The system used for the magnetic measurements of the 120-mm-aperture Nb 3 Sn quadrupole magnet (HQ01e) [3] is based on the FAME (FAst Measurement Equipment) system developed at CERN [2]. The system was adapted for the vertical test cryostat and equipped with a purpose-built, large-diameter search coil. The FAME system is composed furthermore of a GPS timing board (NI-6682), a motor drive (Micro Rotating Unit), a custom encoder board, ten Fast Digital Integrators, and a computer with a data acquisition software (FFMM).
Study of the Present-Day Tectonics and Seismogenetic Sources of the AL-Hoceima Region (Morocco) Using GPS and MTInSAR

Geodetic analysis and modelling of ground deformation da ta is a valuable tool that allows constraining presentday tectonics deformation styles and its implications on the related seismic hazards. We re-analyzed the survey GPS data available from the Nubian and Iberian (Eurasian) plate boundary to develop surface strain maps. We also study a high non-linear deformation time series using a multitemporal interferometry synthetic aperture radar (SAR) technique, such as those spanning coseismic signals. That analysis has been challenging due to the problem of intrinsic temporal smoothing of such multibaseline techniques. We used StaMPS/MTI version with the minimum possible temporal smoothing and we retrieve time series of deformation spanning the coseismic signal due to the 24 February 2004, Mw 6.3, Al-Hoceima (Rif, Morocco). Applying a temporal smoothing (atmospheric filtering) to the pre- and postseismic subsets of the time series we obtained a filtered time series that show a persistent signal during the postseismic period.
TeV gamma ray opacity in PKS 2155-304

Context. Recently observed rapid time variability in the gamma ray emission from the blazar PKS 2155-304 indicates that either the site of gamma ray emission is close to the black hole or the jet has a very high Lorentz factor. Consideration of the opacity of gamma rays close to the black hole provides additional information related to these two possibilities. Aims. We investigate the TeV gamma ray opacity resulting from pair production on soft photons radiated by the black hole accretion disk, considering situations where the radiation produced by the disk is close to that predicted by the Shakura-Sunyaev model and situations where the disk radiation is much less. Methods. We utilise expressions for the pair opacity of very high energy gamma rays developed by Gould and Schreder and Donea and Protheroe and use expressions for the disk radiation field produced by an accretion disk external to a Poynting flux dominated jet. A lower level of disk emission is modelled by using the spectrum corresponding to a lower accretion rate. We also consider changes in the shape of the gamma ray sepctrum as a flare emerges from the optically thick region. Results. If the gravitational power resulting from accretion is dissipated by radiation in the region of the disk external to the jet, then TeV gamma rays are opaque out to of order 40 gravitational radii ≈6 x 10 15 cm from the black hole. However, the opacity is considerably reduced if the disk radiates a negligible amount of gravitational power as would be the case if there is a significant disk wind external to the jet. In either case the absence of spectral changes during observed flares excludes scenarios in which the TeV gamma rays are emitted even in regions of modest pair opacity.
Development of a Remote Handling Robot for the Maintenance of an ITER-Like D-Shaped Vessel

Robotic operation is one of the major challenges in the remote maintenance of ITER vacuum vessel (VV) and future fusion reactors as inner operations of Tokamak have to be done by robots due to the internal adverse conditions. This paper introduces a novel remote handling robot (RHR) for the maintenance of ITER-like D-shaped vessel. The modular designed RHR, which is an important part of the remote handling system for ITER, consists of three parts: an omnidirectional transfer vehicle (OTV), a planar articulated arm (PAA), and an articulated teleoperated manipulator (ATM). The task of RHR is to carry processing tools, such as the viewing system, leakage detector, and electric screwdriver, to inspect and maintain the components installed inside the D-shaped vessel. The kinematics of the OTV, as well as the kinematic analyses of the PAA and ATM, is studied in this paper. Because of its special length and heavy payload, the dynamics of the PAA is also investigated through a dynamic simulation system based on robot technology middleware (RTM). The results of the path planning, workspace simulations, and dynamic simulation indicate that the RHR has good mobility together with satisfying kinematic and dynamic performances and can well accomplish its maintenance tasks in the ITER-like D-shaped vessel.
Does Personality Affect Career Adaptability

Enterprises in the tourism sector are in search of becoming robust in the competitive environment, reducing labour turnover and employing qualified personnel candidates by improving working environments. Therefore, they provide career opportunities for the potentially qualified personnel they employ at appropriate positions to ensure they will provide services for the business in the long term. However, it is notable that there are many factors which affect and support the personnel’ the compatibilities for the positions they want to build their career on. One of these factors is the personnel’s career adaptabilities. In some of the relevant empirical studies in the literature, research showed that the level of job satisfaction was higher [1] and the level of work-related stress was lower in personnel who had high levels of career adaptability [2] . Also, individuals who had good career adaptabilities had a good level of the perception of work-environment adaptation [3] .
A Virtualized Network Architecture for Improving QoS

Recently, researches have shown that today's best-effort Internet with "one fits all" principle comes to an impasse. Addressed to the different QoS requirements of today's network services, we propose a new network architecture based on network virtualization technology for improving Internet QoS. It divides a "thick" network into multiple "thin" virtual networks deploying on the same substrate, each is customized with a special designing goal and runs a customized protocol. Then the traffic with different QoS requirements is classified at the ingress router, and distributed to different virtual networks, which are the most suitable for carrying the special traffic. Also, we can deploy a service on multiple virtual networks, and making them working collaboratively to achieve a better QoS. To verify this idea, a prototype is implemented in LAN-scale network. By some simply designed experiments for comparison, we observe that, by use of our network architecture, service provider with specific QoS requirement can take its choice to choose appropriate virtual networks to achieve better QoS performance.
In Silico Characterization of Genetic Alterations Associated with Mal De Meleda

Mal de Meleda (MDM) is an autosomal recessive skin disorder majorly caused by mutations in the ARS gene encoding SLURP-1 protein secreted by Keratinocytes. A number of genetic alterations have already been reported in SLURP1 associated with MDM, theoretically proposed to affect the integrity of the downstream product. There are a no reports available to the best of our knowledge, which characterize the effect of respective mutations at the protein structural level, which is the focus of this study. The protein sequence of SLURP1 was obtained from the UniProt database and the disease associated alterations were retrieved and mined from the literature resources. Domain analysis showed that the protein belongs to the Ly6/uPAR superfamily, has antitumor activity and is also a marker of late skin differentiation. Complete tertiary structure of SLURP1 was predicted as shown in figure 4, for further structural analysis as was not previously determined and was submitted to the PMDB after systematic evaluation and validation (PMDB ID: PM0077826). Structural abnormalities in the protein due to mutations were explored through comparative structural analysis along with interspecies conservation of the respective residue through phylogenetic analysis. It is expected that this systematic structural analysis will enhance our understanding about the disease mechanism and will also help to develop better diagnosis and designing treatment strategies in the near future against MDM and other relevant disorders.
The RW index: A new distance measure based on random walks

Considering a graph as a network of resistances, Klein and Randić [3] proposed the definition of a distance measure. Indeed, if each edge of the graph represents a resistance of 1Ω, the equivalent resistance of the graph between each pair of vertices may be used as a distance. Based upon random walks in graphs, Stephenson and Zelen [4] built a computational model to find the probability that each edge is used. From a mathematical point of view, both articles are based upon exactly the same model and the link between random walks and the electrical representation was established by Newman [5] when defining an alternative to Freeman’s betweenness centrality [9, 10] based upon random walks. In the present paper, the similitude between these two processes is exploited to propose a new random walks based distance measure that may be defined as the expected length of a walk between any pair of vertices. From this new definition, the RW Index is proposed that sums the expected walks lengths between pairs of vertices exactly in the same way as the Wiener index sums the shortest paths distances or the Kirchhoff index sums the equivalent resistances. In the same way as the Wiener index [6], vertex and edge decompositions of the RW and Kirchhoff indices are proposed. Interestingly, we show that even if the random walks and the resistance distances are based upon a similar mathematical model, they are not equivalent.
Coating PAMAM dendrimer onto PDMS microfluidic chip to resist nonspecific Biomolecules adsorption

The surface of poly(dimethylsiloxane)(PDMS) microfluidic chips were modified using polyamidoamine (PAMAM) dendrimer via physical coating. The results showed that the surface of the modified chips was coated by a dense, uniform, continuous, hydrophilicity layer of PAMAM. The hydrophilic of the chip surface was markedly improved. The contact angle of the chips modified decreased from108.9° to 46.1°. Adenosine and L-lysine were separated via the modified PDMS microfluidic chips. Compared with unmodified chips, the modified chips successfully separated the two biomolecules. The separation efficiencies of adenosine and L-lysine were 7.19×10 4 Plates/m and 8.111×10 4 Plates/m respectively, and the resolutions(RS) was 4.03. This research may provide a new and effective method to resist nonspecific adsorptionon the PDMS surface and the application of PDMS microfluidic chips in the determination of trace biomolecules.
Interdisciplinarity and complexity: An evolving relationship*

In recent decades, the ideas of interdisciplinarity and complexity have become increasingly entwined. This convergence invites an exploration of the links and their implications. The implications span the nature of knowledge, the structure of the university, the character of problem solving, the dialogue between science and humanities, and the theoretical relationship of the two underlying ideas.
Non-linear deformation of sea-wave profiles in intermediate and shallow water

The present paper is a study of the nonlinear deformations of sea-wave profiles in intermediate (20 m depth) and shallow (4 m) water, based on wave staff and bottom pressure in situ measurements. The nonlinear deformations have been decomposed into two elementary classes : asymmetry with respect to the mean water surface and asymmetry with respect to a vertical line passed through the wave crest. The extend of the deformation of the first kind is estimated by computing the experimental statistical distributions of wave crest heights and through depths. These distributions are shown to deviate from the Rayleigh law (applicable to linear sea states), and are well fitted by a second order perturbation model deduced from the Stokes theory. The second kind of nonlinear deformation was observed in shallow water only, and studied by a bi-spectral analysis : this kind of deformation may be interpreted in terms of a phase shift between first and second order components, and related to the phase of the bispectrum. It has been possible, applying this technique to the shallow water data set, to find anew the steepening of the wave front during its progression towards the breaking point. [NOT CONTROLLED OCR]
Optimized resolution of systems of equations

Sparse systems of equations are an essential part of real models, being decisive in simulation or optimization. By increasing the problems size or going closer to reality, these systems increase in complexity and size. There are several proven methods to solve them efficiently, and it is known that a structural reorganization can enhance efficiency. We propose an improvement to the Extended Direct Method algorithm as a preprocessor of the adjacency matrix associated with the system. This method was originated in the Design of Chemical Plant Instrumentation, expanding the functions of its predecessor, the Direct Method, which did not take into account the degree of nonlinearity of model equations and variables.
Outsourcing of outbound logistics in the tea industry

Outsourcing entails shifting of traditional corporate activities to parties outside of the firm with an aim of gaining access to world class capabilities. Under the relentless pressure to compete, companies globally are striving to increase the quality of all their goods and services and at the same time reduce their costs. Professional logistics management can help with both of these objectives hence the significance of outsourcing. This study focussed on three major objectives. First it sought to identify the challenges facing outsourcing of outbound logistics in Tea Division of Unilever Kenya Limited. Secondly, it sought to establish the strategies the Tea Division of Unilever Kenya Limited has adopted to cope with the challenges of outsourcing and thirdly, it sought to determine the impact of outsourcing on the level of customer service. This study was conducted through a case study to establish the responses. Data was collected from primary source through personal interview with respondents who were managers at Unilever Kenya Limited Tea Division in Mombasa. The data obtained was then analysed and interpreted using content analysis technique. The study identified a number challenges that of Unilever Kenya Limited Tea division has faced as a result of outsourcing. The main ones included poor communication, too much management intervention, loss of control, quality of service, lack of performance measures, and skill level of the 3PL personnel.
The Factors Impact on the Service Quality of People’s Credit Funds: The Case of Mekong Delta River in Vietnam

The paper used results of the survey of 100 clients from 24 PCFs in 3 provinces in the Mekong Delta River in Vietnam. By applying Explanatory Factor Analysis methodology, the result of study showed that tangibles (TAN), responsiveness (RES), reliability (REL), assurances (ASS), and empathy (EMP)affecting to the service quality of PCFs in Mekong Delta River in Vietnam. The research found that PCFs’ service quality would be increased if their empathy and tangibility improved. Then, PCFs’ managers should pay more on creating incentives for credit officers to improve their sympathy and understanding customers needs as well as enhancing appearances of PCF staffs and transaction offices.
MAKERJOINT, A NEW CONCEPT FOR JOINING MEMBERS IN TIMBER ENGINEERING - STRENGTH TEST AND FAILURE ANALYSES

The wood construction industries are becoming more focused on climate change and resource depletion, and individual and industrial consumption must reflect a greater degree of concern for the climate and environmental wellbeing. This paper presents a new concept for timber engineering, the purpose being to acquire information about the failure modes and the tensile and compressive strengths of two types of joint, the Simple Gooseneck and Thick Gooseneck, that can be used in a new concept for joining members in timber structures. This Makerjoint concept uses laminated veneer lumber (LVL) as nodes in regions with a pronounced non-uniform stress distribution and sawn timber in regions with a more uniform stress distribution. No metal fasteners or adhesives are used in the joint between timber and LVL. The concept is intended for joints using 3-axis CNC machinery and to be a system for on-site- and pre-fabrication of e.g. small houses, emergency shelters and exhibition stands. The joints have a higher compressive than tensile strength. The joints exhibited brittle failure in tension (beam and/or node failure) and buckling occurred in compression around the thinnest cross section of the beams. Suggestions are made for how the mechanical properties of the joints can be improved.
