Predicting Coal Consumption in South Africa Based on Linear (Metabolic Grey Model), Nonlinear (Non-Linear Grey Model), and Combined (Metabolic Grey Model-Autoregressive Integrated Moving Average Model) Models
Authors: Ma Minglu , Su Min , Li Shuyu , Jiang Feng , Li Rongrong
Published: July 2018

South Africa’s coal consumption accounts for 69.6% of the total energy consumption of South Africa, and this represents more than 88% of African coal consumption, taking the first place in Africa. Thus, predicting the coal demand is necessary, in order to ensure the supply and demand balance of energy, reduce carbon emissions and promote a sustainable development of economy and society. In this study, the linear (Metabolic Grey Model), nonlinear (Non-linear Grey Model), and combined (Metabolic Grey Model-Autoregressive Integrated Moving Average Model) models have been applied to forecast South Africa’s coal consumption for the period of 2017–2030, based on the coal consumption in 2000–2016. The mean absolute percentage errors of the three models are respectively 4.9%, 3.8%, and 3.4%. The forecasting results indicate that the future coal consumption of South Africa appears a downward trend in 2017–2030, dropping by 1.9% per year. Analysis results can provide the data support for the formulation of carbon emission and energy policy.

Authors: Lu Taiguo , Zhang Dawei , Qiu Peizhen , Lian Jiqing , Jing Ming , Yu Binbin , Wen Jing
Published: July 2018

In this article, an ultrathin terahertz dual band metamaterial absorber made up of patterned asymmetrical double-split rings and a continuous metal layer separated by a thin FR-4 layer is designed. Simulation results show that two almost identical strong absorption peaks appear in the terahertz band. When the incident electric field is perpendicular to the ring gaps located at 11 μm asymmetrically, the absorptivity of 98.6% at 4.48 THz and 98.5% at 4.76 THz can be obtained. The absorption frequency and the absorptivity of the absorber can be modulated by the asymmetric distribution of the gaps. The perfect metamaterial absorber is expected to provide important reference for the design of terahertz modulator, filters, absorbers, and polarizers.
Picture Hesitant Fuzzy Set and Its Application to Multiple Criteria Decision-Making
Authors: Wang Rui , Li Yanlai
Published: July 2018

To address the complex multiple criteria decision-making (MCDM) problems in practice, this article proposes the picture hesitant fuzzy set (PHFS) theory based on the picture fuzzy set and the hesitant fuzzy set. First, the concept of PHFS is put forward, and its operations are presented, simultaneously. Second, the generalized picture hesitant fuzzy weighted aggregation operators are developed, and some theorems and reduced operators of them are discussed. Third, the generalized picture hesitant fuzzy prioritized weighted aggregation operators are put forward to solve the MCDM problems that the related criteria are at different priorities. Fourth, two novel MCDM methods combined with the proposed operators are constructed to determine the best alternative in real life. Finally, two numerical examples and an application of web service selection are investigated to illustrate the effectiveness of the proposed methods. The sensitivity analysis shows that the different values of the parameter λ affect the ranking of alternatives, and the proposed operators are compared with several existing MCDM methods to illustrate their advantages.
Interactions of Human Dermal Dendritic Cells and Langerhans Cells Treated with Hyalomma Tick Saliva with Crimean-Congo Hemorrhagic Fever Virus
Authors: Rodriguez Sergio E. , McAuley Alexander J. , Gargili Aysen , Bente Dennis A.
Published: July 2018

Crimean-Congo hemorrhagic fever virus is one the most important and wide spread tick-borne viruses. Very little is known about the transmission from the tick and the early aspects of pathogenesis. Here, we generate human cutaneous antigen presenting cells—dermal dendritic cells and Langerhans cells—from umbilical cord progenitor cells. In order to mimic the environment created during tick feeding, tick salivary gland extract was generated from semi-engorged Hyalomma marginatum ticks. Our findings indicate that human dermal dendritic cells and Langerhans cells are susceptible and permissive to Crimean-Congo hemorrhagic fever virus infection, however, to different degrees. Infection leads to cell activation and cytokine/chemokine secretion, although these responses vary between the different cell types. Hyalomma marginatum salivary gland extract had minimal effect on cell responses, with some synergy with viral infection with respect to cytokine secretion. However, salivary gland extract appeared to inhibit antigen presenting cells (APCs) migration. Based on the findings here we hypothesize that human dermal dendritic cells and Langerhans cells serve as early target cells. Rather affecting Crimean-Congo hemorrhagic fever virus replication, tick saliva likely immunomodulates and inhibits migration of these APCs from the feeding site.

Published: July 2018

Public participation is integrated in the European Floods Directive to ensure engagement of societal actors in selecting and accepting measures. This study assesses the Directive’s public participation process and provides recommendations for its improvement by using Cyprus as a case study. Interviews with the organizers and attendees of the public consultations were carried out to evaluate the process while a citizen survey examined people’s flood awareness and opinions of three household-level flood protection measures (permeable pavements, rainwater harvesting systems, and green roofs). Public consultation organizers were generally satisfied with the process while participants suggested better structured information and a more participatory approach. The majority (77%) of the survey respondents did not know if they lived in a designated flood risk area while 93% were unaware of the public consultations carried out for the Floods Directive. Their perception about the effectiveness of the three flood protection measures was positively associated with their willingness to implement them. The results indicated the need for more participatory methods in the public participation process and better strategies to increase awareness and the engagement of people in flood management. Establishing procedures for evaluating the effectiveness of public participation could contribute to the recognition and improvement of the process.
Impact of the 7Be(α, γ)11C Reaction on the Primordial Abundance of 7Li
Authors: Hartos M. , Bertulani C. A. , Shubhchintak  , Mukhamedzhanov A. M. , Hou S.
Published: July 2018

We calculate the radiative capture cross section for 7Be(α, γ)11C and its reaction rate of relevance for the Big Bang nucleosynthesis (BBN). The impact of this reaction on the primordial 7Li abundance is revised including narrow and broad resonances in the pertinent energy region. Our calculations show that it is unlikely that very low energy resonances in 11C of relevance for the BBN would emerge within a two-body potential model. Based on our results and a comparison with previous theoretical and experimental analyses, we conclude that the impact of this reaction on the so-called “cosmological lithium puzzle” is completely irrelevant.
Measuring Model-independent Masses and Radii of Single-lined Eclipsing Binaries: Analytic Precision Estimates
Authors: Stevens Daniel J. , Gaudi B. Scott , Stassun Keivan G.
Published: July 2018

We derive analytic estimates for the ability with which one can obtain precise, empirical stellar masses and radii via single-lined eclipsing binaries (EBs) in the era of Gaia and TESS. Including stars that host transiting substellar companions, such single-lined EBs already number in the hundreds from ground-based transit surveys and will comprise a major component of the science yield from the upcoming TESS mission. We explore the requirements for obtaining a given fractional precision on the masses and radii of single-lined EBs using primarily empirical means: radial velocity and eclipse measurements along with estimates of the primary’s (1) surface gravity from high-resolution spectroscopy; (2) radius inferred from parallax, effective temperature, and bolometric flux; or (3) surface gravity and density from asteroseismology. We then compare these requirements to the precision obtained from invoking stellar models or empirical relations. We show that, for a fiducial transiting hot Jupiter system, precise, accurate, and essentially model-independent mass and radius measurements for such single-lined EBs will be possible in the era of Gaia. These will be comparable in precision to those obtained with double-lined EBs. Moreover, the systems for which these methods can be applied will vastly outnumber double-lined EBs, thereby possessing the potential to sample a more complete range of stellar types (such as M dwarfs); these systems will also, in many cases, be more amenable to precision metallicity and abundance determinations than are double-lined EBs.
Paraplangia sinespeculo, a new genus and species of bush-cricket, with notes on its biology and a key to the genera of Phaneropterinae (Orthoptera: Tettigonioidea) from Madagascar

Published: July 2018

Madagascar is a well-known hotspot of biodiversity. However, many Orthoptera, and especially the Tettigonioidea, belong to little-studied groups. Here we describe a new genus and species of bush-cricket reared from field-collected eggs.Paraplangiasinespeculogen. nov., sp. nov. belongs to Phaneropterinae and shares diagnostic characteristics with members of the tribe Amblycoryphini and its African subtribe Plangiina stat. nov.Paraplangia, which has a chromosome number of 31 X0, differs from other African members of the tribe and subtribe such asEurycoryphaandPlangia, which both have 29 X0. In addition to morphology, we describe the male calling song, female acoustic response, and mating behavior. As calling song, the male produces two series of short syllables. At the end of the second series the female responds with signals of similar duration and spectral composition as the male sounds (peak about 8-9 kHz). To make future identification easier, a key to all genera of Phaneropterinae found in Madagascar is presented.

Published: July 2018

Hyperbaric oxygen has been used as an adjunctive measure in the treatment of chronic osteomyelitis. The aim of this systematic literature review was to analyze the outcome and the complications of hyperbaric oxygen for chronic osteomyelitis. Forty-five of 96 studies reporting the use of hyper-baric oxygen for 460 patients with chronic osteomyelitis met the inclusion criteria and were analyzed qualitatively. All patients previously received antibiotics and surgical debridement. Mixed bacterial flora was detected in most of the studies.
Staphylococcus aureus
was the isolated pathogen in 12 (60%) of the 20 cohort and in 4 (20%) of the 20 case studies. Adjuvant hyperbaric oxygen was effective in 16 (80%) of the 20 cohort and 19 (95%) of the 20 case studies. Overall, 308 (73.5%) of 419 patients with complete data had a successful outcome and no reported relapse. Available evidence supports a potentially beneficial role of adjunctive hyperbaric oxygen, especially in refractory cases of chronic osteomyelitis. [

Authors: Mattos Meghan K. , Nilsen Marci L. , Lingler Jennifer H.
Published: July 2018

Misdiagnosis, lack of specialists, and patient dismissal of symptoms can contribute to delayed detection of early cognitive impairment. Understanding patient perspectives during and around time of cognitive diagnosis is crucial, as reactions to diagnosis can impact disease management and overall health. The current study conducted semi-structured interviews to explore the experiences of rural-dwelling older adults (
n
= 9) and their caregivers (
n
= 10) surrounding diagnosis of mild cognitive impairment or early-stage Alzheimer's disease at a specialty research center (SRC). Content analysis was performed. Overall, researchers found that older adult participants experienced various cognitive symptoms pre-diagnosis and dyads experienced diagnostic uncertainty prior to the SRC visit. All individuals displayed a range of reactive and information-seeking actions. Nurses play significant roles in the diagnostic and post-diagnostic periods for patients with early-stage cognitive impairment, and clinical diagnostic expertise, appropriate and timely direction of resources, and identification and targeting of early interventions to promote cognitive health are particularly important to this underserved population.

El presente trabajo se enmarca en una labor de investigación metodológica denominada LANBIOEVA (Landscape Biogeographic Evaluation) con una trayectoria de más de 25 años y del que, de momento, es su último eslabón. Se trata de un método global de valoración paisajística centrado en la vegetación como elemento principal de las distintas unidades evaluadas. Hasta la fecha, dicho método se ha plasmado en numerosos trabajos: libros, artículos, capítulos de libro, comunicaciones y ponencias, conferencias etc, referentes a diferentes territorios templados y boreales de Europa y América. Se aplica ahora a la comarca de Collsacabra (Girona) con el objetivo de constatar su eficacia y viabilidad en otros ámbitos a los anteriormente reseñados. De las diferentes formaciones estudiadas las que mejores valoraciones globales obtienen son el hayedo con boj, los pastos mesófilos y el bosque mixto robledal-encinar. Los paisajes de bosque se imponen a los de matorral mientras que los pastos, debido a los altos valores del factor de amenaza también hacen que éstos registren puntuaciones elevadas.

Published: July 2018

Se presenta un estudio geográfico, relacionado con el desarrollo rural y transformación del paisaje en la Cuenca de Tulahuencito, ubicada en la comuna de Monte Patria, Región de Coquimbo, Chile.
El objetivo general de la investigación es conocer y analizar las actividades agrarias y ganaderas que han modificado el entorno natural de la unidad de estudio. Los materiales utilizados fueron hojas de muestreo, máquina fotográfica, grabadora y bibliografía especializada. Los métodos empleados fueron trabajo en terreno, análisis de datos cartográficos y entrevistas. En los resultados se observa una degradación del espacio natural de Tulahuencito, producto de las actividades económicas, como la siembra del grano, el pastoreo de ganado vacuno, caballar y caprino, actividades que se iniciaron junto al desarrollo del modelo exportador de materias primas (1830-1930), continuando con el modelo de sustitución de importaciones (1930-1975) y finalmente el modelo de libre mercado (1975 hasta hoy). A modo de conclusión existe degradación en la zona producto de la agricultura y ganadería, que ha dejado en el territorio claros suelos desnudos, afectando la conservación de la biodiversidad.
Supermercados en México: expansión y espacios de inserción
Authors: Casado Izquierdo José María
Published: July 2018

La expansión de los supermercados en México, favorecida por la llegada de Wal-Mart en los 1990s y su competencia con cadenas nacionales, ha impulsado su penetración tanto en localidades cada vez más pequeñas como en espacios de reciente urbanización, siguiendo así el proceso de desconcentración de la población; pero sobre todo los supermercados se han expandido al interior de las grandes ciudades. La proliferación de formatos más pequeños dirigidos a segmentos de menores ingresos ha permitido aumentar su cobertura poblacional, aunque siguen mostrando una clara preferencia por espacios de baja marginación y por tanto altos ingresos, así como por áreas densamente pobladas. Aunado a este proceso se ha asistido a una creciente concentración de estos establecimientos en unas pocas grandes empresas, ejerciendo Wal-Mart un claro dominio en México.

Geografía histórica de los espacios reales: Alóndiga, Aceca y Barciles, despoblados del rey en la vega del Tajo
Authors: Camarero Bullón Concepción , García Juan Laura
Published: July 2018

Para entender el paisaje del presente se hace necesario conocer el del pasado. Es por ello por lo que cobran especial valor las fuentes geohistóricas catastrales. La vocación de pesquisa universal del catastro de Ensenada hace de este conjunto documental una fuente única para la estudio de los territorios de la Corona de Castilla. A diferencia de algunos otros catastros europeos, éste incluye también las propiedades y sitios del rey. En este trabajo estudiamos la configuración de tres despoblados de propiedad de la Corona ligados al Real Sitio de Aranjuez: Alóndiga, Aceca y Barciles, regados por la Real Acequia del Jarama. Ello nos permite reconstruir el paisaje y aprovechamientos de mediados del siglo XVIII de este espacio y valorar la calidad y complementariedad de los datos aportados por los distintos conjuntos documentales del catastro de Ensenada para este tipo de territorios.
Aplicación de las teorías de la complejidad a la comprensión del territorio
Authors: Rubio Terrado Pascual
Published: July 2018

¿Por qué conocer cómo se comporta un territorio no permite inferir cómo lo hará otro de igual estructura y en las mismas circunstancias? ¿Por qué de los enlaces entre los componentes del capital territorial no derivan siempre idénticas consecuencias? ¿Por qué las acciones de desarrollo territorial no son aplicables indiscriminadamente? Todos nos hemos hecho alguna vez esas preguntas y recurrido al carácter complejo del territorio para responderlas. Pero creemos que el argumento de la complejidad se ha asumido sin más, confundiendo complejo con complicado. Es decir, aunque el carácter complejo del territorio se manifiesta en forma de complicación estructural, en realidad, tiene un fundamento funcional derivado de constituir una totalidad organizada y dinámica formada por entidades naturales y antrópicas que mantienen relaciones no lineales entre sí y con el entorno.
Nuestra hipótesis es que las teorías de la complejidad aportan un bagaje conceptual apropiado para dar respuesta al porqué de su carácter complejo. Por ello, comprender y explicar el territorio, aplicando algunas nociones y principios de la complejidad, constituye nuestro primer objetivo. Argumentar sobre la utilidad de los modelos cualitativos de síntesis territorial para alcanzar el propósito anterior y establecer el segundo.
Contribution of Additive Manufacturing of Rare Earth Material to the Increase in Performance and Resource Efficiency of Permanent Magnets
Authors: Urban Nikolaus , Meyer Alexander , Keller Vitalij , Franke Jörg
Published: July 2018

Powerful permanent magnets are of essential meaning for electric drives as well as for environmental friendly energy conversion in general. The main requirements for these applications are high energy products, coercivity and remanent polarization, thermal stability as well as affordable price. As state of the art, rare earth permanent magnets, frequently consisting of NdFeB based alloys, meet these requirements. When complex geometric shapes like arcs, shells or freeform surfaces are required by the application, a trade-off has to be taken into account between magnetic performance and post magnet-fabrication processing steps. Either bonded magnets can be produced with great variety of geometries while accepting low magnetic performance due to a significant amount of nonmagnetic plastic binder matrix, or sintered blocks with great magnetic performance have to be machined out to the specified shape accepting great effort for grinding or wire cutting as well as a significant loss of valuable material. To overcome the drawback of both conventional established magnet manufacturing processes, Laser Beam Melting (LBM) is investigated to provide an alternative process route for magnet production. This innovative Additive Manufacturing (AM) process offers tool less production of nearly any thinkable geometry by use of a metal powder bed fusing process. Due to the challenging material behavior, a detailed parameter study is presented including a systematic design of experiment (DoE) approach. The connection between process parameters, density and key performance indicators on the B/H-curve is broken down.

Published: July 2018

This paper aims to expand the use of CO2blasting by investigating a cryogenic deburring method for machined metallic materials. In advance to the actual deburring experiments, a streaming analysis based on high-speed video records was conducted for different blasting technologies, in order to gain deeper knowledge about their underlying active principles. For the titanium alloy Ti-6Al-4V and the stainless steel X6CrNiMoTi17-12-2, deburring experiments with three different blasting techniques were conducted and evaluated. It has been shown that cryogenic deburring has the potential to represent an alternative deburring solution for metals.
Magnetic Gearing as a Functional Principle in Electric Drives
Authors: Gerlach Tobias , Vollmer Rolf , Kremser Andreas , Gerling Dieter
Published: July 2018

The partitioned stator flux reversal machine (PS-FRPM) is a novel stator PM machine topology, which exhibits a higher torque capability than its single stator counterpart and the conventional permanent magnet synchronous machine (PMSM). The PS-FRPM consists of two stators, one which carries the armature winding, and one which is equipped with surface mounted permanent magnets. The rotor is sandwiched between the two stators. The separation of the stator allows a better utilization of the machine volume which results in a higher torque density. Furthermore, because the magnets are placed on a stationary component, they can be cooled effectively. Consequently, critical rare-earth materials can be saved.The structure of the PS-FRPM is very similar to that of magnetic gears. In this paper the torque production of a PS-FRPM is described by means of the magnetic gearing effect. First the magnetic gearing effect is introduced and then the corresponding analytics is transferred to the PS-FRPM. Based on Maxwell's stress tensor, the torque contributions of the individual space harmonics are determined. In contrast to conventional machines, the torque in PS-FRPM is produced by several space harmonics in both air gaps.
Combining Use Case Methodology and Architecture Models: A Standardized Description Methodology for Complex Systems
Authors: Schäfer Franziska , Engel Lukas , Kuhn Marlene , Otten Heiner
Published: July 2018

The European and International energy policy targets energy efficiency improvement and CO2reduction. Therefore, renewables are key players within our future energy supply system. In order to ensure security of energy supply and to avoid load peaks, highly interconnected power grids, also known as smart grids, have to deal with irregularities of phenomena such as sunlight, wind, tides and intelligently control these dynamic changes. Such a smart grid is denoted as a complex system. That is characterized by a large quantity of heterogeneous actors, collaborating within a dynamic and highly interconnected network. This results in big challenges in the steps planning, realizing and expanding such a system. These steps need to be based on a standardized description process to cope with the aforementioned challenges. In this paper, we combine the Smart Grid Architecture Model (SGAM) with the Use Case Methodology for describing processes in complex systems. Our new UC-SGAM Methodology exploits the benefits of both approaches and can also be applied to the Reference Architecture Model Industry 4.0 (RAMI4.0). The developed methodology is examined on two overload scenarios of the smart grid. It strongly enhances comparability and simplifies the visualization of complex use cases.
Intersections and Contrasts between Energy Efficiency and Flexibility in Production Machinery Energy - An Analysis Regarding Energy Optimisation
Authors: Brugger Martin , Richter Christoph , Reinhart Gunther
Published: July 2018

Energy efficiency is a well-known and often implemented energy-related activity with a variety of different characteristics and fields of application. Energy efficient solutions, especially for pneumatic and electric intensive processes, are usually applied to minimise the electric and pneumatic energy consumption in the field of production. Especially in complex machinery it must be avoided that the energy consumption influences the productivity or quality of the product. On the other hand, due to volatile energy supply from renewable sources, there is a growing awareness of energy flexibility, which is mainly implemented on energy-intensive processes such as metal production, foundries, chemical processes and paper industry. An increase of the energy flexibility potential of machines often influences the energy efficiency. In other cases, energy efficiency and energy flexibility actions can be conducted without an interaction. This paper compares the definition and characteristics of energy efficiency as well as energy flexibility actions. An application of energy flexibility as well as efficiency actions can lead to optimised energy consumption behaviour of production machinery.

Published: July 2018

There are numerous levers and constraints affecting the sustainability of electric motors. While previous work mostly focuses on individual energy and resource efficiency potentials within single phases of the motor’s lifecycle, this paper summarizes sustainability aspects from three different perspectives, namely from the market, product and process view. The first part of this paper analyzes the electric motor market to emphasize the significance of this industry and to outline the importance of state-regulated efficiency classes. The second part provides an overview of the range of electric motor types and their sustainability characteristics. The third part contains an analysis of manufacturing processes in terms of energy and resource efficiency by pointing out appropriate key figures and optimization approaches. In doing so, the connection of the three perspectives market, product and processes offers a holistic view on sustainability aspects of electric motors.
Transparent Acquisition and Processing of Energy Data in the Field of Industrial Production - Requirements and Applications
Authors: Brandmeier Markus , Eckl Norbert , Weberling Daniel , Franke Jörg
Published: July 2018

Energy efficiency becomes a critical production factor due to legal regulations, sustainable customer-side production requirements and the increasingly volatile supply situation. Energy transparency is of crucial importance for the definition of strategic measures to increase energy efficiency. However, the transparent collection and processing of energy data in production not only forms the basis of industrial energy management, but also facilitates the additional optimization of subareas in the production environment. Especially in the context of production-related data, such as process and product quality data and production planning and control information, as well as combined with expert knowledge, energy data provides a wide range of application fields. This paper analyzes the requirements for a holistic, transparent collection and processing of energy data and identifies possible applications for the optimization of production and production-related areas.
Implementation of an Intralogistics Routing-Service Basing on Decentralized Workspace Digitization
Authors: Scholz Michael , Zhang Xu , Franke Jörg
Published: July 2018

The paper presents an intralogistics routing-service for autonomous and versatile transport vehicles. An infrastructural sensor digitize the workspace of the vehicle and is the basis for the vehicle-specific routing plan. Nowadays, a central computing unit allocates transportation task to a known number of automated guided vehicles, which are usually of the same type. Furthermore, this device generates a routing appropriate to the dimensions and the kinematic gauge of the vehicle fleet. The pathing for each specific vehicle is calculated and the result is send to the different entities. The approach of this paper bases on the digitization of the workspace with a ceiling camera, which divides the scenery into moving obstacles and an adaptive background picture. A central computing unit receives the background picture of several cameras and stitch them together to an overview of the entire workspace, e.g. a production hall. Furthermore, the approach includes the development of automated guided vehicles to versatile autonomous vehicles, were each entity is able to calculate the pathing on a given routing plan. A fleet of versatile autonomous vehicles consists of vehicles with task-specific dimensions and kinematic gauges. Therefore, each vehicle needs its own routing-plan. The solution is that each vehicles uses a vehicle parameter-server and register itself with these parameters at the routing unit. This unit is calculating a routing-plan for each specific vehicle dimension and gauge and providing it. When getting a new task, the vehicles uses this routing-plan to do the pathing. The routing-algorithm is implemented inside the service-layer of the versatile autonomous vehicle system. This approach lowers the amount of data, which is send between the service layer and the transportation entities by reducing the information of the workspace to the possible routes of each specific vehicle. Furthermore, the calculation time for routing and pathing is lowered, because each vehicle is calculating its task-specific path, but the route-map is calculated once for each vehicle-type by the routing-service.

Published: July 2018

This paper addresses the problem of efficiently operating a flexible manufacturing machine in an electricity micro-grid featuring a high volatility of electricity prices. The problem of finding the optimal control policy is formulated as a sequential decision making problem under uncertainty where, at every time step the uncertainty comes from the lack of knowledge about fu-ture electricity consumption and future weather dependent energy prices. We propose to address this problem using deep reinforcement learning. To this purpose, we designed a deep learning architecture to forecast the load profile of future manufacturing schedule from past production time series. Combined with the forecast of future energy prices, the reinforcement-learning algorithm is trained to perform an online optimization of the production ma-chine in order to reduce the long-term energy costs. The concept is empirical-ly validated on a flexible production machine, where the machine speed can be optimized during the production.
Kavain Reduces Porphyromonas gingivalis–Induced Adipocyte Inflammation: Role of PGC-1α Signaling
Authors: Singh Shailendra P. , Huck Olivier , Abraham Nader G. , Amar Salomon
Published: July 2018

A link between obesity and periodontitis has been suggested because of compromised immune response and chronic inflammation in obese patients. In this study, we evaluated the anti-inflammatory properties of Kavain, an extract from Piper methysticum, on Porphyromonas gingivalis–induced inflammation in adipocytes with special focus on peroxisome proliferation–activated receptor γ coactivator α (PGC-1α) and related pathways. The 3T3-L1 mouse preadipocytes and primary adipocytes harvested from mouse adipose tissue were infected with P. gingivalis, and inflammation (TNF-α; adiponectin/adipokines), oxidative stress, and adipogenic marker (FAS, CEBPα, and PPAR-γ) expression were measured. Furthermore, effect of PGC-1α knockdown on Kavain action was evaluated. Results showed that P. gingivalis worsens adipocyte dysfunction through increase of TNF-α, IL-6, and iNOS and decrease of PGC-1α and adiponectin. Interestingly, although Kavain obliterated P. gingivalis–induced proinflammatory effects in wild-type cells, Kavain did not affect PGC-1α–deficient cells, strongly advocating for Kavain effects being mediated by PGC-1α. In vivo adipocytes challenged with i.p. injection of P. gingivalis alone or P. gingivalis and Kavain displayed the same phenotype as in vitro adipocytes. Altogether, our findings established anti-inflammatory and antioxidant effects of Kavain on adipocytes and emphasized protective action against P. gingivalis–induced adipogenesis. The use of compounds such as Kavain offer a portal to potential therapeutic approaches to counter chronic inflammation in obesity-related diseases.
Exodus of clergy: ‘When the fight is just not worth it anymore’ – The role of conflict in responding to the call
Authors: Joynt Shaun
Published: July 2018

Conflict affects clergy’s response to the call. Unresolved conflict negatively influences their decision to remain in full-time pastoral ministry. This contributes to a shortage of clergy in the Roman Catholic Church, but to a lesser extent, the Protestant church, as it faces a distribution or displacement challenge. The shortage negatively affects the church, as clergy equip congregants to live the faith and transmit it to the next generation. The purpose of this study is to discover what factors are involved in responding to the call to full-time pastoral ministry. A practical theological grounded theory approach is used to discover the properties of the basic social process responding to the call and more specifically one of its categories, namely conflict. Semi-structured interviews are conducted and data coded, using Glaser and Strauss’ grounded theory methodology in order to determine a basic social process, namely responding to the call. The category of ‘conflict’ includes properties such as conflict due to lack of communication, dealing with favouritism, conflict with leadership and managing conflict or leaving due to conflict. Osmer’s descriptive-empirical task is used to view the category conflict from a practical theological perspective. The results of this study indicate three responses to the call by clergy who left full-time pastoral ministry: not called in the first place, a dual call (being bi-vocational or seasonal), and being called, but leaving anyway due to, among other factors, conflict.

In this study, we examined the association among the erection hardness score (EHS), pulse wave velocity (PWV), and the presence of carotid artery plaques.

Subjects and Methods:

The study enrolled 67 patients who visited our hospital with the chief complaint of ED. Based on the history at the first visit, 28 of the 67 patients were categorized into the EHS 3–4 group and the remaining 39 into the EHS 0–2 group. The two groups were retrospectively analyzed.

Results:

The PWV points were significantly higher in the EHS 0–2 group than in the EHS 3–4 group (P = 0.047). In consideration for error in age, the modified points (PWV at the first visit – reference PWV by age) were significantly higher in the EHS 0–2 group than in the EHS 3–4 group (P = 0.026). This group also showed a higher detection rate of plaques by carotid ultrasound (66.7%).

Conclusion:

This study showed that patients with lower points of EHS had higher PWV and were more likely to have carotid artery plaques. While ED has occasionally been considered as an early risk marker for the onset of cardiovascular events; this study suggests that the hardness of the penis can be an easier-to-measure and more sensitive index.
Elementary Time Frequency Analysis of EEG Signal Processing
Authors: Puranik Parag , Kshirsagar Dr. R. V. , Motdhare Sagar
Published: July 2018

EEG analysis is used as a tool for medical diagnosis of various diseases related to brain like epilepsy, dementia, brain disorders like stress etc. To identify such neural disorders it is essential to process these signal because of the nonstationary behavior. The time frequency analysis of EEG signals provide the correct visualization of EEG signals to extract the various rhythms of frequencies like alpha, beta, gamma waves. The Wavelet transform is used to carry out the time frequency analysis of EEG signal. Wavelets are used to analyze the EEG signals correctly. Their applications include seizure analysis, modeling of neuron potentials etc. To perform these applications it is necessary to perform the mathematical operations on EEG signal by windowing, filtering and then finally reconstruction.
A Soft Anthropomorphic & Tactile Fingertip for LowCost Prosthetic & Robotic Applications
Authors: Secco E. L. , Moutschen C.
Published: July 2018

Nowadays, prosthetic and robotic hands have reached an amazing dexterity and grasping capability. However, to enhance a proper tactile 'experience', dexterity should be supported by proper sensation of daily life objects which such devices are supposed to manipulate. Here we propose a low cost anthropomorphic solution for the integration of a force sensor within a biologically inspired fingertip. A commercial force resistive sensor is embedded within a human-like soft fingertip made of silicone: the housing of the sensor - a 3D printed bay embedded within the fingertip - is analyzed via Finite Element Analysis and optimized to enhance sensor response. Experiments validate the design and proposed solution.

Mixed Perverse Sheaves on Flag Varieties for Coxeter Groups
Authors: Achar Pramod N. , Riche Simon , Vay Cristian
Published: July 2018

In this paper we construct an abelian category of mixed perverse sheaves attached to any realization of a Coxeter group, in terms of the associated Elias–Williamson diagrammatic category. This construction extends previous work of the first two authors, where we worked with parity complexes instead of diagrams, and we extend most of the properties known in this case to the general setting. As an application we prove that the split Grothendieck group of the Elias–Williamson diagrammatic category is isomorphic to the corresponding Hecke algebra, for any choice of realization.

On the Admissible Fundamental Groups of Curves over Algebraically Closed Fields of Characteristic $p > 0$
Authors: Yang Yu
Published: July 2018

In the present paper, we study the anabelian geometry of pointed stable curves over algebraically closed fields of positive characteristic. We prove that the semi-graph of anabelioids of PSC-type arising from a pointed stable curve over an algebraically closed field of positive characteristic can be reconstructed group-theoretically from its fundamental group. This result may be regarded as a version of the combinatorial Grothendieck conjecture in positive characteristic. As an application, we prove that if a pointed stable curve over an algebraic closure of a finite field satisfies certain conditions, then the isomorphism class of the admissible fundamental group of the pointed stable curve completely determines the isomorphism class of the pointed stable curve as a scheme. This result generalizes a result of A. Tamagawa to the case of (possibly singular) pointed stable curves.

О линейных сечениях спинорного 10-мерного многообразия, I
Authors: Kuznetsov Alexander Gennad'evich
Published: July 2018

В данной работе обсуждается геометрия трансверсальных линейных сечений 10-мерного спинорного многообразия $X$, т. е. компоненты связности ортогонального грассманиана 5-мерных изотропных подпространств в 10-мерном векторном пространстве, снабженном невырожденной квадратичной формой.
В частности, мы показываем, что в случае, когда размерность линейного сечения многообразия $X$ больше или равна 5, его целочисленный мотив Чжоу является мотивом лефшецева типа. Мы также обсуждаем классификацию гладких линейных сечений многообразия $X$ малой коразмерности; в частности, мы проверяем, что существует единственный класс изоморфизма гладких гиперплоских сечений и в точности два класса изоморфизма гладких линейных сечений коразмерности 2. Пользуясь этим, мы определяем естественный квадратичный комплекс прямых, ассоциированный с линейным сечением $X$. Мы также обсуждаем схемы Гильберта линейных пространств и квадрик на многообразии $X$ и его линейных сечениях.

Grammaticalization and lexicalization: suggestions regarding the development of the Chinese change-of-state verb
Authors: LI Wenchao
Published: July 2018

This paper discusses the evolution of the Chinese verb 断 (duàn ‘break’), exploring how the lexicon has transformed from being a substantive transitive verb in the past to the various functions it fulfils in contemporary Chinese: i.e. a resultative complement, an adjective, an adverb and a noun. Findings reveal that duàn was initially transitive and its intransitive function was derived during the Spring and Autumn period (772–476 BC). The two functions co-existed for the rest of the Pre-Qin period (before 221 BC). Duàn’s transition into a resultative complement began during the Eastern Han dynasty (AD 25–220), and its noun function was shaped in the Warring State period (475–221 BC). Finally, Duàn’s adjective and adverb functions are noted to begin in Middle Chinese (AD 420–1279). Although some of these transitions took place more or less simultaneously during overlapping periods, they developed via two separate paths: the process by which duàn developed into a resultative complement, an adverb, and an adjective is that of grammaticalization, while on the other hand, the process by which duàn developed into a noun is that of lexicalization. Essentially, it is the intransitive function that is subject to grammaticalization and it is the transitive function that is subject to lexicalization. In this paper it is therefore proposed that the above diachronic change is taken as a cline, and is put forward as follows: (a) grammaticalization and lexicalization are not distinct processes but rather happen to a lexeme more or less simultaneously; and (b) interrelationship between the two processes is orthogonal.
