Authors: Mukheimer Aiman , Vujaković Jelena , Hussain Azhar , Aydi Hassen , Radenović Stojan , Yaqoob Saman 
Published: November 2019

Abstract
The notion of nonlinear $(\mathcal{F}_{s}, \mathcal{L})$(Fs,L)-contractive multivalued operators is initiated and some related fixed point results are considered. We also give an example to show the validity of obtained theoretical results. Our results generalize many existing ones in the literature.
Stability of delay neural networks with uncertainties via delayed intermittent control
Authors: Tian Yujuan , Wang Fei , Wang Yao , Li Xiaodi 
Published: November 2019

Abstract
In this paper, we investigate the stability of neural networks with both time-varying delays and uncertainties. A novel delayed intermittent control scheme is designed to ensure the globally asymptotical stability of the addressed system. Some new delay dependent sufficient criteria for globally asymptotical stability results are derived in term of linear matrix inequalities (LMIs) by using free-weighting matrix techniques and Lyapunov–Krasovskii functional method. Finally, a numerical simulation is provided to show the effectiveness of the proposed approach.

AbstractThe present study aims to understand the potential of a new and novel type of geothermal play system for high temperature and electricity production: crustal fault zones (CFZ). According to geological and geophysical data, the Pontgibaud fault zone (French Massif Central) is suspected to host an active hydrothermal system at a depth of a few kilometers. The deep geometry of the fault zone and the permeability distribution are the main unknown parameters that are required to assess the geothermal potential of the Pontgibaud site. Structural and thin-section observations, laboratory permeability and connected porosity measurements and X-ray micro-tomography observations suggest that the hydrothermal system behaves like a double matrix-fracture permeability reservoir. Numerical modeling in which we varied the fault dip and the ratio between the fault zone permeability and host rock,R, was performed. Results indicate that three main convective regimes can be identified (weak convection, single cellular-type convection and bicellular convection). For a sufficiently high fault zone permeability (> 1 × 10−15 m2), buoyancy-driven flow creates a positive thermal anomaly of several tens of °C at a depth of 2–5 km. For a vertical fault zone, the thermal anomaly is larger for higherRvalues. Numerical models, then applied to the geologically constrained Pontgibaud fault zone, show that a temperature of 150 °C at a depth of 2500 m can be obtained for a fault zone permeability of 1.6 × 10−14m2. Based on a multi-disciplinary approach, this work establishes a potential predictive tool for future high-temperature geothermal operations within basement rocks hosting large-scale fault systems.

Published: November 2019

AbstractActive faults commonly repeat cycles of sudden rupture and subsequent silence of hundreds to tens of thousands of years, but some parts of mature faults exhibit continuous creep accompanied by many small earthquakes. Discovery and detailed examination of creeping faults on land have been in a rapid progress with the advent of space-borne synthetic aperture radar interferometry. In this study, we measured the spatial variation of the creep rate along the Philippine fault on Leyte Island using ALOS/PALSAR data acquired between October 2006 and January 2011. Prominent creep of$$33\pm {11}$$33±11 mm/year was estimated in northern and central parts of the island except for a locked portion around latitude 11.08–11.20$$^\circ$$∘N. We compared the creep rate distribution along the fault with the slip distribution of the 2017$$M_w$$Mw6.5 Ormoc earthquake which occurred in northern Leyte, estimated from the displacements mapped by ALOS-2/PALSAR-2 interferometric data. The estimated slip of the 2017 earthquake amounted up to 2.5 m and to moment magnitude of 6.49, with the dominant rupture area coinciding with the locked portion identified from the interseismic coupling analysis. Teleseismic waveforms of the 2017 earthquake and another event that occurred in 1947 ($$M_s$$Ms6.9) exhibit close resemblance, indicating two ruptures of rather similar locations and magnitudes with a time interval of 70 years.

AbstractBackgroundTo determine the burden of Rheumatoid Arthritis (RA) on patients’ work productivity and health related quality of life (HRQoL), and examine the influence of several exposure variables; to analyze the progression of RA over 1 year and its impact on work productivity and HRQoL.MethodsInternational multicenter prospective survey including patients in 18 centers in Argentina, Brazil, Colombia and Mexico with diagnosis of RA and aged between 21-55 years. The following standard questionnaires were completed at baseline and throughout a 1-year follow-up: WPAI:RA, WALS, WLQ-25, EQ-5D-3 L and SF-36. Clinical and demographic variables were also collected through interview.ResultsThe study enrolled 290 patients on baseline visit. Overall mean scores at baseline visit were: WPAI:RA (presenteeism) = 29.5% (SD = 28.8%); WPAI:RA (absenteeism) = 9.0% (SD = 23.2%); WPAI:RA (absenteeism and presenteeism) = 8.6% (SD = 22.6%); WALS = 9.0 (SD = 6.1); WLQ-25 = 7.0% (SD = 5.1%); SF-36 Physical Scale = 39.1 (SD = 10.3) and Mental Scale = 45.4 (SD = 11.3); EQ-5D-3 L VAS = 69.8 (SD = 20.4) and EQ-5D-3 L index = 0.67 (SD = 0.23). Higher educational levels were associated with better results in WLQ-25, while previous orthopedic surgeries reduced absenteeism results of WPAI:RA and work limitations in WLQ-25. Higher disease duration was associated with decreased HRQoL. Intensification of disease activity was associated with decreased work productivity and HRQoL, except in WLQ-25. In the longitudinal analysis, worsening in disease activity was associated with a decrease in both work productivity and HRQoL.ConclusionsRA patients are dealing with workplace disabilities and limitations and loss in HRQoL, and multiple factors seems to be associated with this. Worsening of disease activity further decreased work productivity and HRQoL, stressing the importance of disease tight control.

Published: November 2019

AbstractContextSerum uric acid has been linked to risk of type 2 diabetes (T2DM), but debate persists as to whether it plays a causal role. Indeed, it is unclear if changes in uric acid relate to the pathophysiologic determinants of T2DM (insulin resistance, beta-cell dysfunction), as would be expected if causal.ObjectiveTo evaluate the impact of changes in uric acid over 2 years on changes in insulin sensitivity, beta-cell function, and glycemia in women with and without recent gestational diabetes (GDM), a model of the early natural history of T2DM.Design/Setting/ParticipantsAt both 1 and 3 years postpartum, 299 women (96 with recent GDM) underwent uric acid measurement and oral glucose tolerance tests that enabled assessment of insulin sensitivity/resistance (Matsuda index, homeostasis model assessment of insulin resistance [HOMA-IR]), beta-cell function (insulin secretion-sensitivity index-2 [ISSI-2], insulinogenic index/HOMA-IR [IGI/HOMA-IR]), and glucose tolerance.ResultsWomen with recent GDM had higher serum uric acid than their peers at both 1 year (281 ± 69 vs 262 ± 58 µmol/L, P = 0.01) and 3 years postpartum (271 ± 59 vs 256 ± 55 µmol/L, P = 0.03), coupled with lower insulin sensitivity, poorer beta-cell function, and greater glycemia (all P &lt; 0.05). However, on fully adjusted analyses, neither uric acid at 1 year nor its change from 1 to 3 years was independently associated with any of the following metabolic outcomes at 3 years postpartum: Matsuda index, HOMA-IR, ISSI-2, IGI/HOMA-IR, fasting glucose, 2-hour glucose, or glucose intolerance.ConclusionSerum uric acid does not track with changes over time in insulin sensitivity, beta-cell function, or glycemia in women with recent GDM, providing evidence against causality in its association with diabetes.
Closed-loop management of inpatient hyperglycaemia
Authors: Boughton CK , Hovorka R 
Published: November 2019

The prevalence of diabetes in the inpatient setting is increasing, and suboptimal glucose control in hospital is associated with increased morbidity and mortality. Attaining the recommended glucose levels is challenging with standard insulin therapy. Hypoglycaemia and hyperglycaemia are common and diabetes management in hospital can be a considerable workload burden for health-care professionals. Fully automated insulin delivery (closed-loop) has been shown to be safe, and achieves superior glucose control than standard insulin therapy in the hospital, including in those patients receiving haemodialysis and enteral or parenteral nutrition where glucose control can be particularly challenging. Evidence that the improved glucose control achieved using closed-loop systems can translate into improved clinical outcomes for patients is key to support widespread adoption of this technology. The closed-loop approach has the potential to provide a paradigm shift in the management of inpatient diabetes, particularly in the most challenging inpatient populations, and may reduce staff work burden and the health-care costs associated with inpatient diabetes.
Цифровое поколение: гражданская мобилизация и политический протест российской молодежи
Authors: Бродовская Елена Викторовна , Хуанг Тони 
Published: November 2019

В статье представлен анализ базовых трактовок понятия «цифровое гражданство». Основной исследовательский вопрос на который ориентировались авторы: с чем в первую очередь связан высокий уровень протестного потенциала цифрового поколения, это внутренняя характеристика носителей культуры цифрового гражданства или скорее поведенческая стратегия, актуализированная мобилизационными эффектами социальных медиа? Отвечая на поставленный вопрос, авторы реализовали прикладное исследование, применяя метод массового опроса и процедуру онлайн-анкетирования. Полевой этап исследования прошел в июле-сентябре 2019 г. Выборочная совокупность составила 1000 респондентов, репрезентативна по полу, возрасту (в соответствии со статистическими данными о представленности в составе российской молодежи групп 15-19 лет, 20-24 лет и 25-29 лет) и территориальной принадлежности (в выборке воспроизведено соотношение численности молодежи во всех федеральных округах РФ). В рамках исследования были проанализированы основные гражданские и политические практики, востребованные молодыми российскими пользователями в онлайн- и офлайн-средах, масштаб протестной мобилизации в социальных сетях, репертуар протестных сообщений, протестные установки цифровых граждан. Подвергнув кластеризации массив данных опроса, авторы выделили четыре типа носителей разного уровня протестного потенциала в среде российской молодежи: «зрители», «вовлеченные», «активисты», «лидеры». В свою очередь, процедура многомерного шкалирования позволила зафиксировать дифференциацию ценностных профилей и стилей жизни носителей разного типа протестного потенциала. Ключевой вывод исследования заключается в том, что наибольший потенциал протестной активности проявляют вовсе не типичные представители цифрового поколения, а те, чей ценностный выбор и стратегии цифрового гражданства скорее отклоняются от общераспространенных.

An Improved Error Control Model in Packet Switched Wide Area Networks
Authors: Ogbimi Voke , Francis Emuejevoke 
Published: November 2019

Error is an important problem in communication that occurs in shared networks when a packet fails to arrive at the destination or it arrives at the destination but some of the bits are in error or have been altered. In typical packet switched wide area networks, this can occur quite easily when output links are slower than inputs and multiple traffic sources competing for same output link at the same time. Typical for packet switched WAN, the packet transmit input/output buffer and queue of the network devices in their way towards the destination. Moreover, these networks are characterized by the fact that packets often arrive in “burst”. The buffers in the network devices are intended to assimilate these traffic hosts until they can be processed. Nevertheless, the available buffers in the network nodes may fill up rapidly if the network traffic is too high which in turn may lead to discarded packets. The situation cannot be avoided by increasing the size of the buffers, since unreasonable buffer size will lead to excessive end-to-end (e2e) delay. A typical scenario for congestion occurs where multiple incoming link feed into single outgoing link (e.g several Local Area Networks connected to Wide Area Networks). The routers of the networks are highly susceptible for traffic congestion because they are too small for the amount of traffic required to handle.
This paper presented general concepts of Error Control and its mechanisms and its application to packet switched wide area networks An improved model was proposed with reduced error while transmitting packets from one channel to the other.
Simulating the model for reducing error control in packet switched wide area networks increased the number of messages, reduced response time used in transmitting and receiving packets, reduced network utilization.
Histoire et paysages dans quelques écritures de terrain contemporaines : Jean-Christophe Bailly, François Bon, Patrick Deville et Marie Richeux
Authors: Bernard Isabelle 
Published: November 2019

Abstract
This article reviews four works representative of current field writings and attempts to define their major characteristics. First it proposes to encircle in Paysage fer (2000) by François Bon, The Change of scenery. Travels in France (2011) by Jean-Christophe Bailly, Taba-Taba (2017) by Patrick Deville, and Climats de France (2017) by Marie Richeux a common modus operandi; then it identifies in these hybrid works a singular and original writing of the ego, made of biographical and autobiographical fragments, and finally, taking into account the contributions of geocritics, it suggests the viability of ‘egogeographies,’ kinds of own landscapes to each author that a content both testimonial and patrimonial impregnates strongly.
Die Bedeutung des Gelesenen: Eine komparatistische Studie über Rainer Maria Rilke und Marcel Proust
Authors: Slavtscheva Maria 
Published: November 2019

Abstract
The article discusses the hierarchical model of readers’ types outlined by Marcel Proust in his essay “Journées de lecture” and reconstructs Rainer Maria Rilke’s poetics of reading in accordance with the poems “Der Lesende” and “Der Leser” as well as the thematic relevant parts of the novel Die Aufzeichnungen des Malte Laurids Brigge. Based on the conclusions made thereby, it draws attention to the possibilities arising from a comparative reading of the description of the scene in which the young Marcel reads in the garden of Combray from Proust’s Du côté de chez Swann, and Rilke’s poem “Hebend die Blicke vom Buch”. Moreover, it is shown that in this short but complex poem, the German poet fulfills the ideal of a unity of reading and writing emphasized by the French author. Combining the motive of looking away from the book typical of his prose and poetry with Proust’s typical motive of the memory of a certain read, Rilke brings into being a poetic picture of reading, which triggers both the memory and the reflection, and an image of a reader that reveals his own productive reception.
Research on the Transition Section Length of the Mixed Workface Using Gangue Backfilling Method and Caving Method
Authors: Tai Yang , Guo Shuai , Fang Kun 
Published: November 2019

Abstract
Aiming at the problem of the sudden increase of the working resistance of the support in the transition section of the mixed workface, this paper adopts the physical simulation to study the fracture and movement characteristics of the overburden strata in the backfilling section and the caving section after analysis of the system layout of mixed workface. Then, the definition of the transition section of the mixed workface is given. Next, a numerical model of the transition section length is established based on the geological conditions of the Ji15-31010 mixed workface of Pingdingshan No.12 Coal Mine. In the numerical simulation, it is used to study the influence of the advancing length of the mixed workface and the length of the backfilling section on the transition section length. The results show that with the increase of the advancing length of the mixed workface and the decrease of the backfilling section length, the transition section length increases continuously and eventually stabilizes. The range of variation is 6.2~13.5 m, corresponding to 4~9 hydraulic supports with a width of 1.5 m. Based on the above conclusions and the price of transitional hydraulic supports, the 4 transitional hydraulic supports used in the transition section of the Ji15-31010 mixed workface is determined. Filed measurement shows that as the mixed workface is advanced from 10 m to 40 m, the transition section length increases from 2 supports to 4 supports, and decreases to 2 supports again when advanced to 60 m. This indicates that the main roof of the mixed workface between 40 and 60 m experiences the initial caving. The maximum length of the transition section is 6.0 m, corresponding to 4 hydraulic supports.

AbstractIn order to assess the rainfall erosivity in the Pannonian basin, several parameters which describe distribution, concentration and variability of precipitation were used, as well as 9 extreme precipitation indices. The precipitation data is obtained from the European Climate Assessment and Dataset project for the period 1961-2014, for 8 meteorological stations in northern Serbia, 5 in Hungary and 1 in eastern Croatia. The extreme values of precipitation were calculated following the indices developed by the ETCCDI.RclimDexsoftware package was used for indices calculation. Based on statistical analysis and the calculated values, the results have been presented with Geographic Information System (GIS) to point out the most vulnerable parts of the Pannonian basin, with regard to pluvial erosion. This study presents the first result of combined rainfall erosivity and extreme precipitation indices for the investigated area. Results ofPCIindicate presence of moderate precipitation concentration (mean value 11.6). Trend analysis ofFI(mean value 22.7) andMFI(mean value 70.2) implies a shift from being largely in the low erosivity class, to being completely in the moderate erosivity class in the future, thus indicating an increase in rainfall erosivity for most of the investigated area (except in the northwestern parts). Furthermore, the observed precipitation extremes suggest that both the amount and the intensity of precipitation are increasing. The knowledge about the areas affected by strong soil erosion could lead to introducing effective measures in order to reduce it. Long term analysis of rainfall erosivity is a significant step concerning flood prevention, hazard mitigation, ecosystem services, land use change and agricultural production.

AbstractThe Tunisian North-western region, especially Tabarka and Ain-Drahim villages, presents many landslides every year. Therefore, the landslide susceptibility mapping is essential to frame zones with high landslide susceptibility, to avoid loss of lives and properties. In this study, two bivariate statistical models: the evidential belief functions (EBF) and the weight of evidence (WoE), were used to produce landslide susceptibility maps for the study area. For this, a landslide inventory map was mapped using aerial photo, satellite image and extensive field survey. A total of 451 landslides were randomly separated into two datasets: 316 landslides (70%) for modelling and 135 landslides (30%) for validation. Then, 11 landslide conditioning factors: elevation, slope, aspect, lithology, rainfall, normalized difference vegetation index (NDVI), land cover/use, plan curvature, profile curvature, distance to faults and distance to drainage networks, were considered for modelling. The EBF and WoE models were well validated using the Area Under the Receiver Operating Characteristic (AUROC) curve with a success rate of 87.9% and 89.5%, respectively, and a predictive rate of 84.8% and 86.5%, respectively. The landslide susceptibility maps were very similar by the two models, but the WoE model is more efficient and it can be useful in future planning for the current study area.
