description: We investigated the effect of using a synthetic ferrimagnetic (SyF) free layer in MgO-based magnetic tunnel junctions (MTJs) on current-induced magnetization switching (CIMS), particularly for application to spin-transfer torque random access memory (SPRAM). The employed SyF free layer had a Co40Fe40B20/ Ru/ Co40Fe40B20 and Co20Fe60B20/Ru/Co20Fe60B20 structures, and the MTJs(100x(150-300) nm^2) were annealed at 300oC. The use of SyF free layer resulted in low intrinsic critical current density (Jc0) without degrading the thermal-stability factor (E/kBT, where E, kB, and T are the energy potential, the Boltzmann constant, and temperature,respectively). When the two CoFeB layers of a strongly antiferromagnetically coupled SyF free layer had the same thickness, Jc0 was reduced to 2-4x10^6 A/cm^2. This low Jc0 may be due to the decreased effective volume under the large spin accumulation at the CoFeB/Ru. The E/kBT was over 60, resulting in a retention time of over ten years and suppression of the write current dispersion for SPRAM. The use of the SyF free layer also resulted in a bistable (parallel/antiparallel) magnetization configuration at zero field, enabling the realization of CIMS without the need to apply external fields to compensate for the offset field.

description: Information is stored, retrieved and disseminated by information centres hence they rarely survive without the effective utilisation of professional personnel to actualise the set goals such; as the satisfaction of the users and development of the employees. Information centres, like other organisations today, are fast growing with complex operations and structures which are continually changing and thus require effective employees prepared for goal accomplishment. Studies have identified manpower development programmes through articulated managerial planning and control exercise as one of the critical factors that can enhance survival and improve the organisational and personnel’s efficiency. In other word, information centres cannot survive without the use of competent and experienced employees, who must strive to tackle the challenges of a changing world. Investment in manpower development is justified when management is able to get a good return on its investment through staff effectiveness. It is for the above reasons that the paper examined the managerial ability on planning and control towards staff development programme and the resultant impacts on workers’ effectiveness. In addition, this paper concludes that in order to achieve a high level workers’ efficiency, a conscious and well articulated managerial planning and control programmes that will dissolve the issues and implication associated with staff development exercise and improved efficiency must be put in place. It is therefore recommended that managers should at all-time should develop and maintain a coherent and continuous staff development plans and control mechanism that will yield effectiveness starting from the recruitment to retirement period of the personnel.

REEEM-D7.6_Energy Modelling Platform for Europe (EMP-E)
Creators: name: REEEM Project
Publisher: name: Zenodo
Year: 2019

description: The first conference of the “Energy Modelling Platform for Europe“ (EMP-E) took place at the European Commission in Brussels, Belgium on 17-18 May 2017. The EMP-E was organized as a part of the REEEM Project. It is a deliverable assigned to Reiner Lemoine Institute (RLI) in work package 7. The original plan was to add a special track to an existing European conference on environmental informatics. The idea behind, to give an overview on European energy system modelling and pathway analyses to modellers and policy makers, was discussed by the four LCE 21 projects and the Commission, which resulted in the decision that there should be a separate conference for the EMP-E. The headquarters of the European Commission in Brussels was chosen as the venue for the conference. The RLI acted as the main organiser of the conference with support from the Royal Institute of Technology (KTH), Sweden. The Directorate General for Research and Innovation acted as a partner for the organization in Brussels. The thematic discussions were supported by a scientific committee consisting, in addition to the organisers, of important modelling partners of REEEM (i.e., DTU, USTUTT and UCL), representatives of each LCE 21 project as well as from the Directorate Generale for Energy of the European Commission and the Joint Research Centre (JRC). The EMP-E conference resulted in two days of active knowledge sharing filled with a wide spectrum of expertise and insights provided by independent researchers and policy makers. The speakers gave information and technical input on international energy system modelling projects, as well as on models themselves resulting in very diverse topics for discussions. The contributions started with expectations and insights concerning energy system modelling at European Commissions level and with presentations about modelling efforts of important H 2020 projects, such as the EU-Calc and the four LCE (low carbon energy) projects2 . Later, presentations about pathways, sector coupling, case studies, models, and transparency were given by representatives from various international institutions. The conference was concluded by a poster session, a set of interactive panel discussions, and focus groups (workshops dealing with various crucial focus themes). The conference is accompanied by a publication edited by KTH, gathering contributions from the participants concerning the key subjects of the conference. The discussion about a probable next conference was already started at the first day of the venue and will be continued in depth after the evaluation of the feedback survey. The first EMP-E meeting has set the base for this endeavour and has shown that there already is a common mindset within the community and a great willingness to cooperate. This summary will be a very short list with the most important steps of the organisation and it will point to the various links with more information about and from the conference.

We show that the presence of the parameters characterizing EiBI and the topological charge promote significant changes in the angular deflection of light with respect to that one obtained in Schwarzschild spacetime. Using the expression for angular deflection in the strong field limit, we calculate the position and magnification of the respective relativistic images.

description: This paper shows that in intensity correlation measurements there will be clear and unambiguous signals that new-physics particles are, or aren't, parabosons. For a parabosonic field in a dominant single-mode, there is a diagonal P-representation in the "even and odd coherent states" basis. It is used to analyze zero-time-interval intensity correlations of parabosons in a maximum-entropic state. As the mean number of parabosons decreases, there is a monotonic reduction to (2/p) of the constant bosonic ``factor of two'' proportionality of the second-order versus the squared first-order intensity correlation function.

description: This paper is the first paper of a series that will present the derivation of the modal mineralogy of Mars (M3 project) at a global scale from the near-infrared dataset acquired by the imaging spectrometer OMEGA (Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité) on board ESA/Mars Express. The objective is to create and provide a global 3-D image-cube of Mars at 32px/° covering most of Mars surface. This product has several advantages. First, it can be used to instantaneously extract atmospheric- and aerosol-corrected near-infrared (NIR) spectra from any location on Mars. Second, several new data maps can be built as discussed here. That includes new global mineral distributions, quantitative mineral abundance distributions and maps of Martian surface chemistry (wt % oxide) detailed in a companion paper (Riu et al., submitted). Here we present the method to derive the global hyperspectral cube from several hundred millions of spectra. Global maps of some mafic minerals are then shown, and compared to previous works.
A test of the Poincare dodecahedral space topology hypothesis with the WMAP CMB data

description: It has been suggested by Roukema and coworkers (hereafter R04) that the topology of the Universe as probed by the ``matched circles'' method using the first year release of the WMAP CMB data, might be that of the Poincaré dodecahedral space (PDS) model. An excess in the correlation of the ``identified circles'' was reported by R04, for circles of angular radius of ~11 deg for a relative phase twist -36deg, hinting that this could be due to a Clifford translation, if the hypothesized model were true. R04 did not however specify the statistical significance of the correlation signal. We investigate the statistical significance of the signal using Monte Carlo CMB simulations in a simply connected Universe, and present an updated analysis using the three-year WMAP data. We find that our analyses of the first and three year WMAP data provide results that are consistent with the simply connected space at a confidence level as low as 68%.

description: The non-standard Schwinger fermionic representation of the unitary group is studied by using $n$-fermion operators. One finds that the Schwinger fermionic representation of the U(n) group is not unique when $n\ge 3$. In general, based on $n$-fermion operators, the non-standard Schwinger fermionic representation of the U(n) group can be established in a uniform approach, where all the generators commute with the total number operators. The Schwinger fermionic representation of $U(C^{m}_{n})$ group is also discussed.

description: A radiative transfer model was used to reproduce several millions of OMEGA (Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité) spectra representative of igneous terrains of Mars. This task provided the modal composition and grain sizes at a planetary scale. The lithology can be summarized in five mineral maps at km-scale. We found that the low albedo equatorial regions of the Martian surface (from 60°S to 30°N) are globally dominated by plagioclase with average abundance ~50 vol% and pyroxenes with total averaged abundance close to 40 vol%. An evolution of the LCP/(LCP+HCP) ratio is observed with time at the global scale, suggesting an evolution of the degree of partial melting throughout the Martian eras. Olivine and Martian dust are minor components of the modelled terrains. The olivine distribution is quite different from the other minerals because it is found on localized areas with abundance reaching 20 vol%. A statistical approach, to classify the pixels of the abundances maps, using k-means clustering, highlighted seven distinct mineral assemblages on the surface. This classification illustrates that diverse mineralogical units are found in the Noachian and Hesperian terrains, which suggests the presence of various and complex magmatic processes at a global scale during the two oldest eras. The chemical composition was derived from the modal composition maps. The OMEGA-derived chemical composition is quite consistent with several distinctive geochemical characteristics previously considered as fingerprints of the Martian surface. A major discrepancy is in regards to the Fe content that is significantly smaller than soil and rock analyses from GRS and in situ measurements. The discrepancy could be partly explained by the assumptions used for the spectral modelling or could also indicate surface alteration rinds.

description: Few-body systems with large scattering length have universal properties that do not depend on the details of their interactions at short distances. We study the universal bound state properties of the four-boson system with large scattering length in an effective quantum mechanics approach. We compute the four-body binding energies using the Yakubovsky equations for positive and negative scattering length. Moreover, we study the correlation between three- and four-body energies and present a generalized Efimov plot for the four-body system. These results are useful for understanding the cluster structure of nuclei and for the creation of weakly-bound tetramers with cold atoms close to a Feshbach resonance.

description: Let p be an odd prime satisfying Vandiver's conjecture. We consider two objects, the Galois group X of the maximal unramified abelian pro-p extension of the compositum of all Z_p-extensions of the pth cyclotomic field and the Galois group G of the unramified pro-p extension of the cyclotomic field of all p-power roots of unity. We give a lower bound for the height of the annihilator of X as an Iwasawa module. Under some mild assumptions on Bernoulli numbers, we provide a necessary and sufficient condition for G to be abelian. The bound and the condition in the two results are given in terms of the special values of a cup product pairing on cyclotomic p-units. We obtain, in particular, that for p less than 1000, Greenberg's conjecture on the pseudo-nullity of X holds and G is in fact abelian.

description: The study examines the influence of a sloping porous bed on the efficiency of an oscillating water column (OWC) device facing oblique water waves. A vertical, surface piercing, thin plate near a rigid wall approximates the OWC. The system is simulated using a multi-domain boundary element method assuming the linear potential theory. The impact of varying sloping bed structural parameters and influence of the incident wave angle on the performance of the OWC is evaluated and discussed. The significance of this model to act as a breakwater protecting near-shore marine facilities is also highlighted. The OWC efficiency is found to be highly sensitive to the slope of the porous seabed, and seabed porosity is found to stabilize the resonant frequency against changes in water levels. OWCs are found to be more efficient over porous seabeds with higher frictional coefficients. The results indicate optimum values for the parameters governing such a wave energy conversion system that can be used for the design and implementation of the model.

Modeling and analysis of TCP in satellite and mobile data networks interworking with the Internet
Creators: name: Leung, Eva Y.F.
Publisher: name: University of British Columbia
Year: 2009

description: The Transmission Control Protocol (TCP) is the most widely used transport protocol for the Internet because of its good performance over wireline networks. However, TCP performance is seriously degraded in many interconnected heterogeneous wireless and wired networks because their large delays and high packet loss rates violate many of the original TCP assumptions. This thesis presents an analysis and a comparison of the performance of different TCP implementations in networks with satellite links and mobile links interconnected with remote LANs over the Internet, studies the effects of the critical network elements and the chosen TCP parameters on the TCP throughput performance, and obtains the optimal values for the chosen TCP parameters for the different TCP implementations. Compared with TCP Reno and TCP RFC, TCP Vegas not only has a better congestion avoidance mechanism to prevent network congestion and significantly reduce the probability of creating its own losses, but it also has a faster error recovery mechanism to quickly retransmit lost packets. Simulation results show that the satellite network elements and the TCP parameters have greater effect on the throughput of TCP Vegas than on the other implementations under most conditions for networks with satellite links. However, for networks with mobile links, the throughput performance of both TCP Vegas and TCP Reno is strongly affected by the mobile network elements and the TCP parameters. After jointly optimizing the key TCP parameters, the simulation results show that TCP Vegas has more than 100% better throughput than the other TCP implementations for networks with satellite links under a condition of high packet loss rates and long end-to-end delays. However, it just has an approximately 5% better throughput than TCP Reno for networks with mobile links under a condition of high packet loss rates and high mobility rates.

Offshore-Softwareentwicklung in virtuellen Teams. Eine systemtheoretische Betrachtungsweise.
Creators: name: Gey, R.
Publisher: name: Zenodo

description: Virtuelle Teams in der Offshore-Softwareentwicklung gelten als eine mögliche organisatorische Maßnahme, den Anforderungen einer globalisierten Wirtschaft im Bereich der Softwareentwicklung gerecht zu werden. Sie nutzen die Möglichkeiten der modernen Informations- und Kommunikationstechnik, um an verteilten Standorten, in unterschiedlichen Zeitzonen und mit Mitarbeitern unterschiedlichster Herkunft zusammenzuarbeiten. Das Forschungsanliegen dieser Arbeit liegt in der empirischen Untersuchung der Zusammenarbeit solcher Teams. Theoretische Basis dafür liefert die neuere Systemtheorie nach Niklas Luhmann. Es soll die Frage geklärt werden, inwiefern sich virtuelle Teams in der Zusammenarbeit von Face-to-Face-Teams aus einer systemtheoretischen Sicht unterscheiden. Im empirischen Teil der Arbeit wurde ein qualitativer Zugang mit Hilfe von leitfadengestützten Experteninterviews gewählt. Daraufhin wurden die Daten einer Inhaltsanalyse unterzogen. Die Resultate zeigen, dass die Kommunikation der untersuchten Teams wesentliche Defizite im Vergleich zu Face-to-Face-Teams aufweist und die Bildung von Subgruppen innerhalb der Teams auslöst, was die Zusammenarbeit entscheidend erschwert.

description: Images of natural systems may represent patterns of network-like structure, which could reveal important information about the topological properties of the underlying subject. However, the image itself does not automatically provide a formal definition of a network in terms of sets of nodes and edges. Instead, this information should be suitably extracted from the raw image data. Motivated by this, we present a principled model to extract network topologies from images that is scalable and efficient. We map this goal into solving a routing optimization problem where the solution is a network that minimizes an energy function which can be interpreted in terms of an operational and infrastructural cost. Our method relies on recent results from optimal transport theory and is a principled alternative to standard image-processing techniques that are based on heuristics. We test our model on real images of the retinal vascular system, slime mold and river networks and compare with routines combining image-processing techniques. Results are tested in terms of a similarity measure related to the amount of information preserved in the extraction. We find that our model finds networks from retina vascular network images that are more similar to hand-labeled ones, while also giving high performance in extracting networks from images of rivers and slime mold for which there is no ground truth available. While there is no unique method that fits all the images the best, our approach performs consistently across datasets, its algorithmic implementation is efficient and can be fully automatized to be run on several datasets with little supervision.

description: In the course of investigating regular subalgebras of E(10) related to cosmological solutions of 11-dimensional supergravity supporting an electric 4-form field, a class of rank 10 Coxeter subgroups of the Weyl group of E(10) was uncovered (hep-th/0606123). These Coxeter groups all share the property that their Coxeter graphs have incidence index 3, i.e. that each node is incident to three and only three single lines. Furthermore, the Coxeter exponents are either 2 or 3, but never infinity. We here go beyond subgroups of the Weyl group of E(10) and classify all rank 10 Coxeter groups with these properties. We find 21 distinct Coxeter groups of which 7 were already described in hep-th/0606123. Moreover, we extend the classification to the rank 11 case and we find 252 inequivalent rank 11 Coxeter groups with incidence index 4, of which at least 28 can be regularly embedded into E(11).

Quantum measurements with, and yet without an Observer

description: It is argued that Feynman's rules for evaluating probabilities, combined with von Neumann's principle of psycho-physical parallelism, help avoid inconsistencies, often associated with quantum theory. The former allows one to assign probabilities to entire sequences of hypothetical Observers' experiences, without mentioning the problem of wave function collapse.The latter limits the Observer's (e.g., Wigner's friend's) participation in a measurement to the changes produced in material objects,thus leaving his/her consciousness outside the picture.

description: By combining accurate heat capacity and X-ray resonant scattering results we have resolved the long standing question regarding the nature of the quadrupolar ordered phases in UPd_3. The order parameter of the highest temperature quadrupolar phase has been uniquely determined to be antiphase Q_{zx} in contrast to the previous conjecture of Q_{x^2-y^2} . The azimuthal dependence of the X-ray scattering intensity from the quadrupolar superlattice reflections indicates that the lower temperature phases are described by a superposition of order parameters. The heat capacity features associated with each of the phase transitions characterize their order, which imposes restrictions on the matrix elements of the quadrupolar operators.

Crossover from a fission-evaporation scenario towards multifragmentation in spallation reactions

description: Mostly for the purpose of applications for the energy and the environment and for the design of sources of neutrons or exotic nuclides, intense research has been dedicated to spallation, induced by protons or light projectiles at incident energies of around 1 GeV. In this energy range, while multifragmentation has still a minor share in the total reaction cross section, it was observed to have, together with fission, a prominent role in the production and the kinematics of intermediate-mass fragments, so as to condition the whole production of light and heavy nuclides. The experimental observables we dispose of attribute rather elusive properties to the intermediate-mass fragments and do not allow to classify them within one exclusive picture which is either multifragmentation or fission. Indeed, these two decay mechanisms, driven by different kinds of instabilities, exhibit behaviours which are closely comparable. High-resolution measurements of the reaction kinematics trace the way for probing finer features of the reaction kinematics.

description: Coronal magnetic flux ropes are generally considered to be the core structure of large-scale solar eruptions. Recent observations found that solar eruptions could be initiated by a sequence of "flux feeding," during which chromospheric fibrils rise upward from below, and merge with a pre-existing prominence. Further theoretical study has confirmed that the flux feeding mechanism is efficient in causing the eruption of flux ropes that are wrapped by bald patch separatrix surfaces. But it is unclear how flux feeding influences coronal flux ropes that are wrapped by hyperbolic flux tubes (HFT), and whether it is able to cause the flux-rope eruption. In this paper, we use a 2.5-dimensional magnetohydrodynamic model to simulate the flux feeding processes in HFT configurations. It is found that flux feeding injects axial magnetic flux into the flux rope, whereas the poloidal flux of the rope is reduced after flux feeding. Flux feeding is able to cause the flux rope to erupt, provided that the injected axial flux is large enough so that the critical axial flux of the rope is reached. Otherwise, the flux rope system evolves to a stable equilibrium state after flux feeding, which might be even farther away from the onset of the eruption, indicating that flux feeding could stabilize the rope system with the HFT configuration in this circumstance.

description: Recent studies have revealed effects of various tree species on soil physical and chemical properties. However, effects of various tree species on composition and activity of soil microbiota and the relevant controls remain poorly understood. We evaluated the influence of tree species associated with two different mycorrhizal types, ectomycorrhiza (EcM) and arbuscular mycorrhiza (AM), on growth, biomass and metabolic activity of soil fungal and bacterial communities using common garden tree species experiments throughout Denmark. The soil microbial communities differed between six European tree species as well as between EcM (beech, lime, oak and spruce) and AM (ash and maple) tree species. The EcM tree species had higher fungal biomass, fungal growth and bacterial biomass, while AM species showed higher bacterial growth. The results indicated that microbial community composition and functioning differed between groups of tree species with distinct litter qualities that generate soil C/N ratio and soil pH differences. The mycorrhizal association only partly explained litter quality and soil microbial species differences since lime was more similar to AM tree species. In addition, our results indicated that tree species-mediated soil pH and C/N ratio were the most important variables shaping microbial communities with a positive effect on bacterial and a negative effect on fungal growth rates. The results suggest that tree species-mediated microbial community composition and activity may be important drivers of the different vertical soil C distribution previously observed in AM and EcM tree species.

Identification and control of white water recycle systems
Creators: name: Chen, Huiping
Publisher: name: University of British Columbia
Year: 2009

description: In recent years, more environmental restrictions have been imposed on pollutant discharge and fresh water consumption from paper mills. This gives increasing motivation to industry for closing paper machine white water system. With inter-related recycle loops, the white water system exhibits complicated dynamics. Identification and control of such a system in the presence of dynamics uncertainty is the primary goal of this research. Motivated by its simplicity and strong features in modelling unstructured processes, the Laguerre series representation is chosen for system modelling and on-line identification. A controller for the white water recycle system must be able to handle unmeasurable disturbances, process time delays, interactions inside and outside the plant etc. It has been proved that generalized predictive control (GPC) is a robust algorithm for adaptive applications. This research presents the first application of the Laguerre model based adaptive GPC for the control of the recycle system. Simulation results show that this control scheme provides excellent servo performance and load disturbance rejection.
Stepwise Spectral Swapping with Three Neutrino Flavors

description: We develop a framework for studying collective three-flavor neutrino oscillations based on the density matrix formalism. We show how techniques proven useful for collective two-flavor neutrino oscillations such as corotating frames can be applied readily to three-flavor mixing. Applying two simple assumptions and the conservation of two ``lepton numbers'' we use this framework to demonstrate how the adiabatic/precession solution emerges. We illustrate with a numerical example how two stepwise spectral swaps appear naturally if the flavor evolution of the neutrino gas can be described by such a solution. For the special case where mu and tau flavor neutrinos are equally mixed and are produced with identical energy spectra and total numbers, we find that one of the spectral swaps in the three-flavor scenario agrees with that in the two-flavor scenario when appropriate mixing parameters are used. Using the corotating frame technique we show how the adiabatic/precession solution can obtain even in the presence of a dominant ordinary matter background. With this solution we can explain why neutrino spectral swapping can be sensitive to deviations from maximal 23-mixing when the ``mu-tau'' matter term is significant.

description: The lunar surface has been exposed to the space environment for billions of years and during this time has accumulated records of a wide range of astrophysical phenomena. These include solar wind particles and the cosmogenic products of solar particle events which preserve a record of the past evolution of the Sun, and cosmogenic nuclides produced by high-energy galactic cosmic rays which potentially record the galactic environment of the Solar System through time. The lunar surface may also have accreted material from the local interstellar medium, including supernova ejecta and material from interstellar clouds encountered by the Solar System in the past. Owing to the Moon's relatively low level of geological activity, absence of an atmosphere, and, for much of its history, lack of a magnetic field, the lunar surface is ideally suited to collect these astronomical records. Moreover, the Moon exhibits geological processes able to bury and thus both preserve and 'time-stamp' these records, although gaining access to them is likely to require a significant scientific infrastructure on the lunar surface.
