description: We construct the manifestly N=4 supersymmetric off-shell superfield "master" action for any number n of the N=4 supermultiplets (4, 4, 0) described by harmonic analytic superfields q^{+a}(ζ, u), a= 1, ... 2n, subjected to the most general harmonic constraints. The action consists of the sigma-model and Wess-Zumino parts. We present the general expressions for the target space metric, torsion and background gauge fields. The generic target space geometry is shown to be weak HKT (hyper-Kähler with torsion), with the strong HKT and HK ones as particular cases. The background gauge fields obey the self-duality condition. Our formulation suggests that the weak HKT geometry is fully specified by the two primary potentials: an unconstrained scalar potential {\cal L}(q^+, q^-, u)|_{θ= 0} which is the θ= 0 projection of the superfield sigma-model Lagrangian, and a charge 3 harmonic analytic potential {\cal L}^{+ 3a}(q^+, u)|_{θ= 0} coming from the harmonic constraint on q^{+ a}. The reductions to the strong HKT and HK geometries amount to simple restrictions on the underlying potentials. We also show, using the N=2 superfield approach, that the most general bosonic target geometry of the N=4, d=1 sigma models, of which the weak HKT geometry is a particular case, naturally comes out after adding the mirror (4, 4, 0) multiplets with different transformation laws under N=4 supersymmetry and SO(4) R symmetry. Thus the minimal dimension of the target spaces exhibiting such a "weakest" geometry is 8, which corresponds to a pair of the mutually mirror (4, 4, 0) multiplets.

Inward FDI in Indonesia and its policy context

description: Inward foreign direct investment (IFDI) in Indonesia has been an important element of the country's economic development process. Following the introduction of the first foreign direct investment (FDI) law early in the 'New Order' era (1966-1998), IFDI flows to Indonesia were relatively large. Indonesia was hit hard during the Asian financial crisis in 1997-1998, when net IFDI inflows fell sharply. In the first half of 2004, IFDI started to grow again. Indonesia still faces some uncertainties relating to the implementation of regional autonomy and to the high costs of running businesses caused by inadequate infrastructure, restrictive labor regulations and corruption. Nevertheless, the availability of vast reserves of highly diversified natural resources, a huge domestic market potential, a cheap labor force, and continued reforms in the direction of a market-based economy, including privatizations and open access to almost all sectors, are likely to boost IFDI.

description: Portugal's performance in attracting inward foreign direct investment (IFDI) during the economic and financial crisis in 2009 was poor, below the low figures that it had already recorded in the previous couple of years, although Portugal did not record negative FDI inflows like competing countries such as Ireland (in 2008) and Hungary (in 2009). The country's difficulties in attracting IFDI are, however, structural. The "golden" years of the early 1990s, when Portugal emerged as an attractive and fashionable location, are past. The country's IFDI performance throughout the first decade of the 21st century was, in general, weak. In 2009, Spain, France and Brazil were the main sources of IFDI in Portugal. In spite of the Government's commitment to attracting IFDI, policy design and implementation have fallen short in the increasingly fierce competition for international investment.

description: Minimal Flavour Violation can be realized in several ways in the lepton sector due to the possibility of Majorana neutrino mass terms. We derive the scalar potential for the fields whose background values are the Yukawa couplings, for the simplest See-Saw model with just two right-handed neutrinos, and explore its minima. The Majorana character plays a distinctive role: the minimum of the potential allows for large mixing angles -in contrast to the simplest quark case- and predicts a maximal Majorana phase. This points in turn to a strong correlation between neutrino mass hierarchy and mixing pattern.

description: We employ the 'square root' of the Maxwell Lagrangian (i.e. \surd(F_{μν}F^{μν})), coupled with gravity to search for the possible linear potentials which are believed to play role in confinement. It is found that in the presence of magnetic charge no confining potential exists in such a model. Confining field solutions are found for radial geodesics in pure electrically charged Nariai- Bertotti-Robinson (NBR)-type spacetime with constant scalar curvature. Recently, Guendelman, Kaganovich, Nissimov and Pacheva, [Phys.Lett.B704(2011)230] have shown that superposed square root with standard Maxwell Lagrangians yields confining potentials in spherically symmetric spacetimes with new generalized Reissner-Nordström-de Sitter / -anti-de Sitter black hole solutions. In NBR spacetimes we show that confining potentials exist even when the standard Maxwell Lagrangian is relaxed.

description: A computational camera uses a combination of optics and software to produce images that cannot be taken with traditional cameras. In the last decade, computational imaging has emerged as a vibrant field of research. A wide variety of computational cameras have been demonstrated - some designed to achieve new imaging functionalities and others to reduce the complexity of traditional imaging. In this article, we describe how computational cameras have evolved and present a taxonomy for the technical approaches they use. We explore the benefits and limits of computational imaging, and describe how it is related to the adjacent and overlapping fields of digital imaging, computational photography and computational image sensors.

The Apterostigma pilosum species-complex needs athorough taxonomic revision. Lattke (1997) provides a general diagnosis for the putative species in the complex: eyes with 5–6 ommatidia along the mi- nor axis; mesopleural ventral carina present or absent but never prominent, lamelliform, nor thick and shin- ing; frontal lobes in cephalic dorsal view triangular or uniformly convex; anterolateral mesonotal prominence absent; and dorsal postpetiolar profile in lateral view strongly curved. The above specimens all agree with this diagnosis. Distribution. The species of the Apterostigma pilosum complex are widely distributed in Central and South America, ranging from Tamaulipas in Mexico south to Buenos Aires, Argentina.

description: The dynamics of the quantum discord for two identical qubits in both two independent single-mode cavities and a common single-mode cavity are discussed. For the initial Bell state with correlated spins, while the entanglement sudden death can occur, the quantum discord vanishes only at discrete moments in the independent cavities and never vanishes in the common cavity. Interestingly, quantum discord and entanglement show opposite behaviors in the common cavity, unlike in the independent cavities. For the initial Bell state with anti-correlated spins, quantum discord and entanglement behave in the same way for both independent cavities and a common cavity. It is found that the detunnings always stabilize the quantum discord.

description: Introduction: The increasing trend of dementia is an undeniable health phenomenon with multifaceted impacts on the lives of patients and their families. The implicated factors are not solely biological, raising questions about the extent to which management and other parameters can contribute to limiting this clinical phenomenon. Purpose:This paper aims to analyze the nine (9) factors associated with dementia, according to the Lancet committee. All non-pharmacological interventions proposed will be presented, and the ultimate goal is to draw conclusions about their effectiveness. Methodology: The research will be conducted through a systematic review. Articles will be sought on search engines such as PubMed, Cochrane and Scopus, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses ( PRISMA ) system for inclusion and exclusion criteria of studies included in the research. Results: The adoption of a healthier lifestyle, such as quitting smoking, physical exercise, and proper nutrition, has been proven to reduce the risk of dementia through cardiovascular complications and other developing pathologies. This strengthens the Lancet committee position regarding the preventive value of the nine factors and their potential correlation with dementia. Discussion – Conclusions: Many study results lead to the conclusion that biological vulnerability leading to pathogenesis can be limited through a complex of interventions and behaviors, when adopted by individuals at the appropriate age and established as patterns of behavior and lifestyle. Given that the Lancet committee examines some of these parameters, it is expected that the research will reconfirm the correlation of a healthy lifestyle with protection against biological impairments that may lead to dementia over time or more immediately.

description: In recent years, computer games have become increasingly social and collaborative in nature. Massively multiplayer online games, in which a large number of players collaborate with each other to achieve common goals in the game, have become extremely pervasive. By working together towards a common goal, players become more engrossed in the game. In everyday work environments, this sort of engagement would be beneficial, and is often sought out. We propose an approach to software engineering called HALO that builds upon the properties found in popular games, by turning work into a game environment. Our proposed approach can be viewed as a model for a family of prospective games that would support the software development process. Utilizing operant conditioning and flow theory, we create an immersive software development environment conducive to increased productivity. We describe the mechanics of HALO and how it could fit into typical software engineering processes.
title: Mortality benefits and intussusception risks of rotavirus vaccination in low- and middle-income countries

description: Mortality benefits and intussusception risks of rotavirus vaccination in low- and middle-income countries Infant rotavirus vaccines have led to substantial reductions in rotavirus gastroenteritis (RVGE) hospital admissions and costs, but some studies have reported an elevated risk of intussusception, a rare bowel disorder, in vaccinated infants. The aim of this thesis is to quantify the potential mortality benefits and intussusception risks of alternative rotavirus vaccination schedules in 135 low- and middle-income countries (LMICs). The thesis begins with an introduction to the topic and background to the literature and concludes with some final reflections on the research and its relevance for informing national decisions about vaccine safety and optimal scheduling of rotavirus vaccines. The main body of the thesis includes a series of research papers which address specific topics relevant to the estimation of mortality benefits and intussusception risks. These include methods for estimating: RVGE deaths <5 years of age; RVGE age distributions <5 years; vaccine coverage and timeliness; rotavirus vaccine efficacy and waning; and, intussusception incidence, age distributions, and case fatality ratios in children <5 years of age. The final research paper brings together this evidence and uses a national-level vaccine decision support model to estimate the potential rotavirus mortality benefits (averted RVGE deaths <5 years of age) and risks (excess intussusception deaths <5 years of age) of 18 possible vaccination schedules in 135 LMICs. Scenarios with and without age restrictions are evaluated. Rotavirus vaccines are found to have a favourable benefit-risk profile in LMICs. Mortality benefits and intussusception risks are estimated to vary considerably by country and choice of rotavirus vaccination schedule. Schedules involving birth and booster doses could further increase benefits and reduce risks, but more research is needed to assess their feasibility, safety and impact.

description: We consider tensor products of N=2 minimal models and non-compact conformal field theories with N=2 superconformal symmetry, and their orbifolds. The elliptic genera of these models give rise to a large and interesting class of real Jacobi forms. The tensor product of conformal field theories leads to a natural product on the space of completed mock modular forms. We exhibit families of non-compact mirror pairs of orbifold models with c=9 and show explicitly the equality of elliptic genera, including contributions from the long multiplet sector. The Liouville and cigar deformed elliptic genera transform into each other under the mirror transformation.

title: Navigating the immuno-epidemiology of malaria: Potential metrics for surveillance and cluster randomised trials
Creators: name: Wu, L
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2018

description: As malaria endemic countries progress towards elimination, accurately measuring community-level transmission is critical for monitoring control strategies and the design of efficacy trials. However, measuring malaria transmission often faces challenges in pre-elimination settings due to the complexity of human immunity and its interaction with vector and parasite dynamics. This study evaluates current and emerging epidemiological measures of malaria transmission, and explores the use of novel serological markers of malaria infection as metrics in surveillance and cluster-randomised trials (CRTs). The relative sensitivity of commonly used surveillance diagnostics - polymerase chain reaction (PCR), rapid diagnostic tests (RDTs), and microscopy – are cross-compared with respect to their accuracy in quantifying cluster-level prevalence of malaria infection. These are further evaluated against immunological measures of transmission based on antibody responses to two malaria parasite antigens - PfMSP119 and PfAMA1 - used extensively in serological surveillance for the last decade. To investigate novel serological markers of malaria infection, a multiplexed immunoassay was used to characterise post-infection antibody dynamics to 20 Plasmodium falciparum antigens. This was based on a subset of 192 individuals from an all-age longitudinal cohort study in The Gambia. Antibody responses against several antigens showed accuracy in detecting infection in the preceding six months. These may have potential utility in measuring time since infection or short-term changes in transmission. However, variations in immune response by age and transmission intensity were observed and should be taken into consideration for future optimisation of serological assays. Antigens identified as the most promising biomarkers of recent infection were used to estimate cluster-level transmission in four villages in The Gambia. Serological responses are compared between dry and wet season and geographical regions of low and high transmission intensity. Their application was also extended to compare study arms of a cluster-randomised trial in the Zambezi Region, Namibia, comparing the effectiveness of reactive focal case detection, reactive focal mass drug administration, and reactive vector control. These findings may help to inform the development of new serological diagnostic assays for malaria, their use in future malaria surveillance and elimination strategies, and the design of cluster-randomised trials in low transmission settings.

description: We present new results on the Ly-alpha emission-line kinematics of 18 z~2-3 star-forming galaxies with multiple-peaked Ly-alpha profiles. With our large spectroscopic database of UV-selected star-forming galaxies at these redshifts, we have determined that ~30% of such objects with detectable Ly-alpha emission display multiple-peaked emission profiles. These profiles provide additional constraints on the escape of Ly-alpha photons due to the rich velocity structure in the emergent line. Despite recent advances in modeling the escape of Ly-alpha from star-forming galaxies at high redshifts, comparisons between models and data are often missing crucial observational information. Using Keck II NIRSPEC spectra of H-alpha (z~2) and [OIII] 5007 (z~3), we have measured accurate systemic redshifts, rest-frame optical nebular velocity dispersions and emission-line fluxes for the objects in the sample. Accurate systemic redshifts allow us to translate the multiple-peaked Ly-alpha profiles into velocity space, revealing that the majority (11/18) display double-peaked emission straddling the velocity-field zeropoint with stronger red-side emission. We compare our data with the predictions of simple models for outflowing and infalling gas distributions around high-redshift galaxies. While popular "shell" models provide a qualitative match with many of the observations of Ly-alpha emission, we find that in detail there are important discrepancies between the models and data, as well as problems with applying the framework of an expanding thin shell of gas to explain high-redshift galaxy spectra. Our data highlight these inconsistencies, as well as illuminating critical elements for success in future models of outflow and infall in high-redshift galaxies. [Abridged]

description: Italian companies started to invest abroad in the 1960s in search of new markets. However, Italy's outward foreign direct investment (OFDI) performance is quite modest compared with that of other European Union (EU) countries, mainly due to structural characteristics like the low number of large firms, the specialization in traditional low- and medium-technology manufacturing industries and the almost negligible activity in advanced services. The global economic and financial crisis seriously affected the Italian economy. However, the positive trend of Italian OFDI was not interrupted, and in 2009 OFDI flows remained stable compared to 2008. Habitually silent on this policy area in earlier decades, the Italian Government has recently shown a more favorable stance toward OFDI, introducing specific policy measures addressed to small and medium-sized enterprises, which have started to expand strongly abroad "“ these now constitute almost 90% of Italian multinational enterprises (MNEs).

description: Osteoarthritis (OA) is a degenerative joint disease which has been shown frequently to follow injury of the connective tissues of the knee. In order to restore the mechanical function of the joint following such injury, a more complete understanding of joint mechanics is necessary. In this study, a system was developed for the measurement of in-vitro joint and structure loads during robotic application of in-vivo kinematics to the ovine stifle joint. In-vivo kinematics of 3 animals were measured, following which kinematics were re-applied in-vitro using a parallel manipulator. Resulting joint and structure loads were measured, and the sensitivity of these load measurements to kinematic perturbations determined. The development of this method demonstrated the importance of spatial positioning in obtaining valid load measurements. Future directions involve improvement of spatial accuracy, following which the system is expected to provide a useful tool for the estimation of in-vivo joint and structure loading.

description: Considering its high energy demand, the manufacturing industry has grand potential for demand response studies to increase the use of clean energy while reducing its own electricity cost. Production scheduling, driven by smart demand response services, plays a major role in adjusting the manufacturing sector to the volatile energy market. As a state-of-the-art method for scheduling problems, reinforcement learning has not yet been applied to the job-shop scheduling problem with demand response objectives. To address this gap, we conceptualize and implement deep reinforcement learning as a single-agent approach, combining energy cost and makespan minimization objectives. We consider makespan as an ancillary objective in order not to entirely abandon the timely completion of production operations while assigning different weights to both objectives and analyzing the resulting trade-offs between them. Our main contribution is the integration of the energy cost-related objective. We present two innovative reward functions, which consider the dynamic energy prices to select a job for the machine or allow the machine idle. The reinforcement learning agent finds optimal schedules determined by cumulative energy costs for benchmark scheduling cases from the literature.
The role of red blood cells in wound healing
Creators: name: Akbari, Amir
Publisher: name: University of British Columbia
Year: 2012

description: Wound healing is a complex & intricate process that involves the coordinated efforts of an enormous number of unique tissues & cell lineages. Regardless of the cause, defects in this well-orchestrated process often lead to dramatic morbidity and treatments that are among the most costly, from an economic perspective. In an effort to understand the wound healing mechanisms and to establish more effective treatments, the roles of many underlying factors and cell types have been extensively studied. In spite of their ubiquitous presence and involvement in coagulation, thrombosis, and inflammation, the role(s) of red blood cells (RBC) in wound healing remains to be elucidated - RBCs are generally thought of as inert bystanders in wound healing. Recent evidence regarding RBCs novel secondary functions and their ability to actively participate in dynamic biological processes such as inflammation, led us to investigate their role in wound healing. In order to explore RBCs involvement in wound healing, three specific objectives were successfully accomplished in this research project: (1) utilizing Western blot and proteomic analyses the presence of five erythrocytic 14-3-3 isoforms were confirmed, (2) it was established that treatment of dermal fibroblasts with RBC lysate for 24 hours results in significant (p<0.01) upregulation of matrix metalloproteinase (MMP)-1, -2, -3, fibronectin and down regulation of type-I collagen, and (3) utilizing specific inhibitors for three mitogen activated protein kinase (MAPK) pathways, the extracellular regulated protein kinase 1/2 (ERK 1/2) pathway was found to be involved in the RBC mediated upregulation of MMP-1 in dermal fibroblasts. Collectively, this project‟s findings, demonstrate that RBCs are equipped with some form of anti-fibrogenic factor which enables them to actively participate in the dynamic process of ECM modulation, through the activation of ERK 1/2 pathway. Such observations, could potentially pave the way for designing novel treatments for fibrotic disorders such as hypertrophic scars and keloids, which are frequently caused by thermal injuries, surgical incisions and other deep-dermal injuries.

description: Programming with dependent types is a blessing and a curse. It is a blessing to be able to bake invariants into the definition of data-types: we can finally write correct-by-construction software. However, this extreme accuracy is also a curse: a data-type is the combination of a structuring medium together with a special purpose logic. These domain-specific logics hamper any effort of code reuse among similarly structured data. In this paper, we exorcise our data-types by adapting the notion of ornament to our universe of inductive families. We then show how code reuse can be achieved by ornamenting functions. Using these functional ornament, we capture the relationship between functions such as the addition of natural numbers and the concatenation of lists. With this knowledge, we demonstrate how the implementation of the former informs the implementation of the latter: the user can ask the definition of addition to be lifted to lists and she will only be asked the details necessary to carry on adding lists rather than numbers. Our presentation is formalised in a type theory with a universe of data-types and all our constructions have been implemented as generic programs, requiring no extension to the type theory.

description: This paper is interested in improving the quality of Arabic-English statistical machine translation (SMT) on highly dialectal Arabic text using morphological knowledge. We present a light-weight rule-based approach to producing Modern Standard Arabic (MSA) paraphrases of dialectal Arabic out-of-vocabulary words and low frequency words. Our approach extends an existing MSA analyzer with a small number of morphological clitics and transfer rules. The generated paraphrase lattices are input to a state-of-the-art phrase-based SMT system resulting in improved BLEU scores on a blind test set by 0.56 absolute BLEU (or 1.5% relative).

description: Malaysia is still perceived as an important destination for foreign direct investment (FDI). Deregulation by the Malaysian government in 1986 with a new round of Pioneer status tax holidays, tax allowances for expansion projects, liberal rules for firms operating in free trade zones (FTZs), and tax exemptions are encouraging stronger FDI inflows (IFDI). IFDI flows reached a peak in 1988-1993 as export-oriented foreign multinational enterprises (MNEs) relocated manufacturing production operations to Malaysia to benefit from cheap labor, government incentives and liberal conditions for manufacturing FDI. After 1996, due to the Asian financial crisis in 1997-1998, IFDI flows into Malaysia decreased and subsequently recorded the lowest level in 2001 as a result of the world trade recession. Following steady growth in 2002-2007, IFDI in Malaysia fell dramatically in 2008 and 2009 due to the global economic crisis. However, a strong resumption in the first quarter of 2010 and government efforts, including continued liberalization of manufacturing and services, the Government Transformation Programme, promoting new key economic areas, and the active role of the Ministry of International Trade and Industry (MITI), contributed to an increase in inward FDI flows in the second quarter of 2010.

description: A first characterization of many exoplanets has recently been achieved by the observational determination of their radius. For some planets, a measurement of the luminosity has also been possible, with many more directly imaged planets expected in the future. The statistical characterization of exoplanets through their mass-radius and mass-luminosity diagram is thus becoming possible. This is for planet formation and evolution theory of similar importance as the mass-distance diagram. Our aim in this and a companion paper is to extend our formation model into a coupled formation and evolution model. We want to calculate in a self-consistent way all basic characteristics (M,a,R,L) of a planet and use the model for population synthesis calculations. Here we show how we solve the structure equations describing the gaseous envelope not only during the early formation phase, but also during gas runaway accretion, and during the evolutionary phase at constant mass on Gyr timescales. We then study the in situ formation and evolution of Jupiter, the mass-radius relationship of giants, the influence of the core mass on the radius and the luminosity both in the "hot start" and the "cold start" scenario. We put special emphasis on the comparison with other models. We find that our results agree very well with those of more complex models, despite a number of simplifications. The upgraded model yields the most important characteristics of a planet from its beginning as a seed embryo to a Gyr old planet. This is the case for all planets in a synthetic planetary population. Therefore, we can now use self-consistently the statistical constraints coming from all major observational techniques. This is important in a time where different techniques yield constraints on very diverse sub-populations of planets, and where its is challenging to put all these constraints together in one coherent picture.

description: We present a method for tracking and predicting the propagation and evolution of coronal mass ejections (CMEs) using the imagers on the STEREO and SOHO satellites. By empirically modeling the material between the inner core and leading edge of a CME as an expanding, outward propagating ellipsoid, we track its evolution in three-dimensional space. Though more complex empirical CME models have been developed, we examine the accuracy of this relatively simple geometric model, which incorporates relatively few physical assumptions, including i) a constant propagation angle and ii) an azimuthally symmetric structure. Testing our ellipsoid model developed herein on three separate CMEs, we find that it is an effective tool for predicting the arrival of density enhancements and the duration of each event near 1 AU. For each CME studied, the trends in the trajectory, as well as the radial and transverse expansion are studied from 0 to ~.3 AU to create predictions at 1 AU with an average accuracy of 2.9 hours.

description: The women and girls of Kisumu face an array of challenges that hinder their rights to gender equality and empowerment. For instance, girls have limited access to postprimary education and do not participate in formal employment, mainly because they do not have the necessary education and experience. Approximately 57 percent of the unemployed are female. Women also have a much higher HIV prevalence rate than men (13.8 percent and 8.4 percent respectively). Adolescent girls are particularly at risk of being withdrawn from school to care for HIV-positive family members. Women in the city also experience gender-based violence and are victims of harmful traditional practices such as polygamy, wife inheritance and coerced adolescent marriages.

description: In many industries, such as the automotive industry or consumer electronics, the demand for lithium-ion batteries is increasing significantly. The state of the art in battery production is energy-consuming and cost-intensive. The drying process of the viscous active material applied to the conductor foils, together with the coating process, is responsible for more than half of the production costs of an electrode. The high energy consumption of conventional drying processes, such as convection drying, must be reduced. Therefore, lasers are used to dry the active material of the electrodes. Further advantages are the low footprint and the increased process flexibility. Moreover, the controlled energy deposition and the spatially selective heat input increase the energy efficiency of the process innovation laser drying. In this review, the results of experiments on drying anodes by laser are compared with the results of convection drying. For this purpose, different production process parameter combinations and material compositions for anodes are chosen in order to be able to derive the process and material influences on the electrode quality.

description: Health care professionals rely on software to simulate anatomical and physiological elements of the human body for purposes of training, prototyping, and decision making. Software can also be used to simulate medical processes and protocols to measure cost effectiveness and resource utilization. Whereas much of the software engineering research into simulation software focuses on validation (determining that the simulation accurately models real-world activity), to date there has been little investigation into the testing of simulation software itself, that is, the ability to effectively search for errors in the implementation. This is particularly challenging because often there is no test oracle to indicate whether the results of the simulation are correct. In this paper, we present an approach to systematically testing simulation software in the absence of test oracles, and evaluate the effectiveness of the technique.

description: In road haulage, transports are interrupted by truck drivers to comply with driving and rest times. On long-distance routes, these interruptions lead to a considerable increase in transport time. Transport interruption can be avoided by so-called relay traffic: a vehicle (e. g. semi-trailer) is handed over to a rested driver at the end of the driving time. This type of transport requires a certain company size. In Germany, however, transport companies have 11 employees on average. Intra-company relay traffic is therefore not economically viable for most transport companies. To organize an intermodal transport across forwarding companies, long-distance routes need to be split into partial routes to divide them between freight forwarders and carriers. This paper presents a data concept for an algorithm to find the best possible route sections along a previously defined start and endpoint. The developed data concept includes order-specific data, forwarder-specific data, real-time traffic data, geographical data as well as data from freight forwarding software and telematics to be the basis for the route sectioning algorithm. In this paper, different data sources, external services and logistic systems are analyzed and evaluated. It is shown which data is needed and what the best ways are to select and derive this data from the different data sources.

description: We numerically construct an one-parameter family of initial data of an expanding inhomogeneous universe model which is composed of regularly aligned black holes with an identical mass. They are initial data for vacuum solutions of the Einstein equations. We call this universe model the "black hole universe" and analyze the structure of these initial data. We study the relation between the mean expansion rate of the 3-space, which corresponds to the Hubble parameter, and the mass density of black holes. The result implies that the same relation as that of the Einstein-de Sitter universe is realized in the limit of the large separation between neighboring black holes. The applicability of the cosmological Newtonian $N$-body simulation to the dark matter composed of black holes is also discussed. The deviation of the spatial metric of the cosmological Newtonian $N$-body system from that of the black hole universe is found to be smaller than about 1% in a region distant from the particles, if the separation length between neighboring particles is 20 times larger than their gravitational radius. By contrast, the deviation of the square of the Hubble parameter of the cosmological Newtonian $N$-body system from that of the black hole universe is about 20% for the same separation length.
