Common Radio Resource Management Strategies for Quality of Service Support in Heterogeneous Wireless Networks

Hoy en dia existen varias tecnologias que coexisten en una misma zona formando un sistema heterogeneo. Ademas, este hecho se espera que se vuelva mas acentuado con todas las nuevas tecnologias que se estan estandarizando actualmente. Hasta ahora, generalmente son los usuarios los que eligen la tecnologia a la que se van a conectar, ya sea configurando sus terminales o usando terminales distintos. Sin embargo, esta solucion es incapaz de aprovechar al maximo todos los recursos. Para ello es necesario un nuevo conjunto de estrategias. Estas estrategias deben gestionar los recursos radioelectricos conjuntamente y asegurar la satisfaccion de la calidad de servicio de los usuarios. Siguiendo esta idea, esta Tesis propone dos nuevos algoritmos. El primero es un algoritmo de asignacion dinamica de recusos conjunto (JDRA) capaz de asignar recursos a usuarios y de distribuir usuarios entre tecnologias al mismo tiempo. El algoritmo esta formulado en terminos de un problema de optimizacion multi-objetivo que se resuelve usando redes neuronales de Hopfield (HNNs). Las HNNs son interesantes ya que se supone que pueden alcanzar soluciones sub-optimas en cortos periodos de tiempo. Sin embargo, implementaciones reales de las HNNs en ordenadores pierden esta rapida respuesta. Por ello, en esta Tesis se analizan las causas y se estudian posibles mejoras. El segundo algoritmo es un algoritmo de control de admision conjunto (JCAC) que admite y rechaza usuarios teniendo en cuenta todas las tecnologias al mismo tiempo. La principal diferencia con otros algorimos propuestos es que estos ultimos toman las dicisiones de admision en cada tecnologia por separado. Por ello, se necesita de algun mecanismo para seleccionar la tecnologia a la que los usuarios se van a conectar. Por el contrario, la tecnica propuesta en esta Tesis es capaz de tomar decisiones en todo el sistema heterogeneo. Por lo tanto, los usuarios no se enlazan con ninguna tecnologia antes de ser admitidos.
Regulation of alternative polyadenylation by Nkx2-5 and Xrn2 during mouse heart development

Transcription factors organize gene expression profiles by regulating promoter activity. However, the role of transcription factors after transcription initiation is poorly understood. Here, we show that the homeoprotein Nkx2-5 and the 5’-3’ exonuclease Xrn2 are involved in the regulation of alternative polyadenylation (APA) during mouse heart development. Nkx2-5 occupied not only the transcription start sites (TSSs) but also the downstream regions of genes, serving to connect these regions in primary embryonic cardiomyocytes (eCMs). Nkx2-5 deficiency affected Xrn2 binding to target loci and resulted in increases in RNA polymerase II (RNAPII) occupancy and in the expression of mRNAs with long 3’untranslated regions (3’ UTRs) from genes related to heart development. siRNA-mediated suppression of Nkx2-5 and Xrn2 led to heart looping anomaly. Moreover, Nkx2-5 genetically interacts with Xrn2 because Nkx2-5+/-Xrn2+/-, but neither Nkx2-5+/-nor Xrn2+/-, newborns exhibited a defect in ventricular septum formation, suggesting that the association between Nkx2-5 and Xrn2 is essential for heart development. Our results indicate that Nkx2-5 regulates not only the initiation but also the usage of poly(A) sites during heart development. Our findings suggest that tissue-specific transcription factors is involved in the regulation of APA. DOI: http://dx.doi. org/10.7554/eLife.16030. 001

Survie et comportement des oiseaux limicoles hivernant sur le Banc d’Arguin, Mauritanie

Using automated and manual radio-telemetry and resightings of individual colour-ringed birds, we assessed the daily use of space of red knots Calidris canutus canutus at a tropical wintering area along the Sahara coast, the Banc d’Arguin in Mauritania. Con- firming earlier suggestions, we found that birds were very faithful to their roosts and that the daily foraging range was small; in the course of several winter months birds used an area of only 2–16 km of intertidal area. We found no differences between their movements in daylight and at night. Additionally, individuals seem to return to exactly the same locations in subsequent win- ters. This pattern is very different from red knots win- tering in the temperate Wadden Sea. Here, they readily change roost sites and easily cover areas of about 800 km in the course of weeks but, just as in Mauri- tania, no differences between day and night are appar- ent. In northern Patagonia and north-western Australia, red knots have range sizes closer to those on the Banc d’Arguin, but here they do show differences in space use between day and night. Ecological explanations for these contrasting patterns require further comparative data based on in-depth studies on the predictability of the food base and the presence of diurnal and nocturnal predators.
Pulmonary vein stenosis after radiofrequency ablation: in vivo optical coherence tomography insights.

A 56-year-old woman with paroxysmal atrial fibrillation refractory to medical treatment developed left inferior pulmonary vein (LIPV) stenosis 3 months after catheter ablation. Radiofrequency was delivered at the antrum of the vein, but some ostial applications were needed to achieve vein disconnection at the carina between both the left PV. …
Onychomadesis outbreak linked to hand , foot , and mouth disease , Spain , July 2008

In July 2008 an onychomadesis outbreak in a nursery setting was reported in Saragossa (Spain). Some of the cases had previously suffered from hand, foot and mouth disease (HFMD). In order to study the outbreak and to determine the relation between the two diseases, two epidemiological studies were conducted: a descriptive study focused on cases and a retrospective cohort study. Samples from stool, pharynx and nails were obtained from cases for microbiological analysis. During the study period, 27 children fulfilled the case definition. The average age was 1.8 years. A case shed on average four nails (minimum one maximum twelve). Twenty-four of the 27 cases had previously presented with HFMD which started an average of 40 days before the onset of onychomadesis (relative risk: 14). Unidentified non-polio enterovirus (n=10), coxsackie B1 (n=4) and coxsackie B2 virus (n=3) were isolated in 28 specimens obtained from 14 cases. The analysis showed a strong association between HMFD and onychomadesis. Microbiological results have not been conclusive; consequently more studies are necessary to determine the causal agent of infectious onychomadesis.
Efficiency-based hp-refinement for finite element methods

Two efficiency-based grid refinement strategies are investigated for adaptive finite element solution of partial differential equations. In each refinement step, the elements are ordered in terms of decreasing local error, and the optimal fraction of elements to be refined is determined based on efficiency measures that take both error reduction and work into account. The goal is to reach a pre-specified bound on the global error with a minimal amount of work. Two efficiency measures are discussed, work times error and accuracy per computational cost. The resulting refinement strategies are first compared for a one-dimensional model problem that may have a singularity. Modified versions of the efficiency strategies are proposed for the singular case, and the resulting adaptive methods are compared with a threshold-based refinement strategy. Next, the efficiency strategies are applied to the case of hprefinement for the one-dimensional model problem. The use of the efficiency-based refinement strategies is then explored for problems with spatial dimension greater than one. The work times error strategy is inefficient when the spatial dimension, d, is larger than the finite element order, p, but the accuracy per computational cost strategy provides an efficient refinement mechanism for any combination of d and p.
Walker Circulation response to global warming

The structure and variance of the Walker Circulation is analyzed by examining 21 models of the Coupled Model Intercomparison Project Phase 5 (CMIP5) and 24 models of Phase 3 (CMIP3). In this study the equatorial zonal circulation is characterized by a zonal pressure gradient in combination with a surface temperature gradient across the Pacific. The climate models in this study include twentieth century and twenty-first century simulations. Several authors characterized the circulation intensity by setting an index derived by a zonal difference of spatial means. The variability of the Walker Circulation measured by the indices according to recent studies is analyzed in this study. A connection between the temperature and pressure gradient can be seen and most models indicate a weakening trend in the twenty-first century. Nevertheless the signal of global warming is too weak to be detected. No significant outcome can be obtained by any of the chosen indices which suggests that different meteorological parameters might be more meaningful to gain clearer evidence for the Walker Circulation variability. Future projections are characterized by high uncertainty which is mostly due to model uncertainty. The climate models presented here illustrate the Walker Circulation variability unequally when using the defined measure of the Walker Circulation intensity. Hence the definition of an index needs to be reconsidered and an improvement of climate models reproducing atmospheric circulation variability still remains to be a focus of current research.
Plan and operation of the NHANES I Epidemiologic Followup Study, 1992.

OBJECTIVES The NHANES I Epidemiologic Followup Study (NHEFS) is a longitudinal study that uses as its baseline those adult persons 25-74 years of age who were examined in the first National Health and Nutrition Examination Survey (NHANES I). NHEFS was designed to investigate the association between factors measured at baseline and the development of specific health conditions. The three major objectives of NHEFS are to study morbidity and mortality associated with suspected risk factors, changes over time in participants' characteristics, and the natural history of chronic disease and functional impairments. METHODS Tracing and data collection in the 1992 Followup were undertaken for the 11,195 subjects who were not known to be deceased in the previous surveys. No additional information was collected in the 1992 NHEFS for the 3,212 subjects who were known to be deceased before the 1992 NHEFS data collection period. RESULTS By the end of the 1992 NHEFS survey period, 90.0 percent of the 11,195 subjects in the 1992 Followup cohort had been successfully traced. Interviews were conducted for 9,281 subjects. An interview was conducted for 8,151 of the 8,687 surviving subjects; 551 interviews were administered to a proxy respondent because the subject was incapacitated. A proxy interview was conducted for 1,130 of the 1,392 decedents identified in the 1992 NHEFS. In addition, 10,535 facility stay records were collected for 4,162 subjects reporting overnight facility stays. Death certificates were obtained for 1,374 of the 1,392 subjects who were identified as deceased since last contact. Approximately 32 percent of the NHEFS cohort is known to be deceased with a death certificate available for 98 percent of the 4,604 NHEFS decedents.
POLARIZATION TRENDS ACROSS THE EUROPEAN REGIONS

This paper examines the level of polarization in the distribution of GDP per capita in 263 European regions over the period 1995-2008. To that end I have completed the non-parametric analysis of the external shape of the distribution with the information provided by a series of measures proposed by Esteban and Ray (1994) and Esteban et al. (2007). The results show a reduction in the degree of polarization across the European regions throughout the study period. This conclusion does not depend on the specific number of groups considered in the analysis and the value assigned to the polarization sensitivity parameter. The analysis carried out also shows that polarization and spatial autocorrelation have followed a similar trend between 1995 and 2008, which reveals the importance of the geographical location of the various regions in explaining the variations registered by the distribution of GDP per capita over time.
Wpływ OFE na saldo Funduszu Emerytalnego

System otwartych funduszy emerytalnych (OFE) zostal utworzony w Polsce w 1999 r. OFE finansowane są z 37,4% skladki emerytalne, podczas gdy reszta środkow pozostaje w publicznym systemie zdefiniowanych skladek (SDS). Udzial finansowania OFE w skladce emerytalnej jest stosunkowo wysoki w porownaniu z innymi krajami o podobnych systemach, zwlaszcza biorąc pod uwage obecnie wysoki deficyt strukturalny systemu emerytalnego. W 2010 r. Okolo OFE zasilily środki w wysokości 1,6% PKB. Skumulowana wartośc transferow od początku reformy siegnela 16,5% PKB. Koszt ten byl w pelni pokryty z budzetu panstwa. Wielkośc transferow rodzi pytanie o jej ramy czasowe i graniczne. Okres przejściowy akumulacji aktywow w OFE bedzie jeszcze trwal wiele lat. Tylko osoby urodzone po 1968 r. zostaly zobowiązane do przystąpienia do OFE, co oznacza, ze wyplaty z nowego systemu istotną role zaczną odgrywac po 2030-40. Aby oszacowac wplyw OFE na saldo przeplywow środkow publicznych, obliczono przekazywane do OFE skladki emerytalne oraz nizsze wydatki na emerytury wyplacane z I filara. Wplyw utworzenia OFE zostal oszacowany poprzez zestawienie symulowanego salda publicznego funduszu emerytalnego w dwoch scenariuszach: jeden z udzialem OFE a drugim, alternatywnym, gdzie cala skladka emerytalna wklad pozostaje w publicznym systemie. Roznica miedzy saldem funduszy emerytalnych w tych dwoch scenariuszach stanowi realny koszt wprowadzenia OFE. Co ciekawe, wykonane analizy wskazują ze OFE bedzie generowac koszty (choc niewielkie) nawet na koncu horyzontu analizy (rok 2060). Uwzgledniając koszt finansowania, do 2060 r. Skumulowane koszty transferow do OFE osiągną 94% PKB.
ANALISIS INDEKS KUALITAS TANAH PERTANIAN DI LAHAN PASIR PANTAI SAMAS YOGYAKARTA (ANALYSIS OF SOIL QUALITY INDEX FOR SAND DUNE AGRICULTURE LAND AT SAMAS YOGYAKARTA)

The utilization of sand dune at Samas for agriculture land has been started since 1986 and still expanding. The main treatment applied to improve soil properties in the land was adding clay soil and cattle manure with dose based on the prior research. This study was conducted in Bulak Tegalrejo, Samas, Bantul, aimed to calculate soil quality index for different age of land use, so that it could be recognized relationship between period of land utilization and soil quality improvement. The result showed that according to soil quality index, the applied treatment could improve soil quality. The better soil quality, the higher soil quality index. Land utilized for 19 and 11 years had better soil quality than virgin land, while land utilized for 3 years had no significant different compared to the virgin land. Soil quality index for the three locations were 0.35; 0.32; 0.28 and 0.17 for land uitilzed for 19, 11, 3 and virgin land respectively.
Spatial variation in springtime food resources influences the winter body mass of roe deer fawns

It is well established that the dynamics of mammalian populations vary in time, in relation to density and weather, and often in interaction with phenotypic differences (sex, age and social status). Habitat quality has recently been identified as another significant source of individual variability in vital rates of deer, including roe deer where spatial variations in fawn body mass were found to be only about a tenth of temporal variations. The approach used was to classify the habitat into blocks a priori, and to analyse variation in animal performance among the predefined areas. In a fine-grained approach, here we use data collected over 24 years on 1,235 roe deer fawns captured at known locations and the plant species composition sampled in 2001 at 578 sites in the Chiz forest to determine the spatial structure at a fine scale of both vegetation and winter body mass of fawns, and then to determine links between the two. Space and time played a nearly equal role in determining fawn body masses of both sexes, each accounting for about 20% of variance and without any interaction between them. The spatial distribution of fawn body mass was perennial over the 24 years considered and predicted values showed a 2 kg range according to location in the reserve, which is much greater than suggested in previous work and is enough to have strong effects on fawn survival. The spatial distribution and the range of predicted body masses were closely similar in males and females. The result of this study is therefore consistent with the view that the life history traits of roe deer are only weakly influenced by sexual selection. The occurrence of three plant species that are known to be important food items in spring/summer roe deer diets, hornbeam (Carpinus betulus), bluebell (Hyacinthoides sp.) and Star of Bethlehem (Ornithogalum sp.) was positively related to winter fawn body mass. The occurrence of species known to be avoided in spring/summer roe deer diets [e.g. butcher’s broom (Ruscus aculeatus) and beech (Fagus sylvatica)], was negatively related to fawn body mass. We conclude that the spatial variation in the body mass of fawns in winter in this forest is as important as the temporal variation, and that the distribution of plant species that are actively selected during spring and summer is an important determinant of spatial variation in winter fawn body mass. The availability of these plants is therefore likely to be a key factor in the dynamics of roe deer populations.
Effects of FK506 on regeneration and macrophages in injured rat sciatic nerve

Abstract Effects of FK506 [5.0 mg/kg body weight (BW), subcutaneous, daily] on nerve regeneration and presence of macrophages in lesioned rat sciatic nerves were studied. Models of autologous nerve graft or a nerve crush lesion were used and regeneration was evaluated by immunocytochemistry (also used to detect ED1/ED2 macrophages) and sensory pinch reflex test, respectively. Treatment with FK506 did not increase regeneration distance or regeneration rate in the autologous nerve grafts. However, regeneration distances after nerve crush were significantly longer following treatment with FK506. The number of macrophages (ED1/ED2) in nerve grafts increased over time, but treatment with FK506 had limited effects only in the presence of ED2 macrophages. Present and previously published studies may imply that there is a time‐related and type‐of‐injury‐related profile of FK506's pro‐regenerative effect.
NLM Medical Text Indexer: A Tool for Automatic and Assisted Indexing

This study was designed to define the mechanism of bupivacaine inhibition of ICa,L. METHODS: Cardiomyocytes were enzymatically dispersed from hamster ventricles. Certain voltage-and time-depen­ dencies of ICa,L were recorded using the whole-cell patch clamp method in the presence and absence of different concentrations of bupivacaine. RESULTS: Bupivacaine, in a concentration-dependent manner (10-300 microM), tonically inhibited the peak amplitude of ICa,L. The inhibition was characterized by an
Repeatable measurement of Twitter user impact NASA and the great American Eclipse of 2017

NASA is viewed as part of the frontier of human knowledge by several generations, and is relied upon to educate the public on astronomical matters. For decades NASA has provided not only North America but the entire world with information and events pertaining to our Universe and beyond. With the Great American Eclipse of 2017, NASA’s production was crucial to the general public’s awareness and understanding of the event. To date, it may have been NASA’s largest production of an event spanning many social media platforms and hundreds of Media outlets. With the eruption of data mining avenues and techniques available, being able to study and quantify such major events from a “reach” perspective has become of utmost importance for many of the groups involved. Our goal with this paper is to understand how the public perceived the social media coverage that NASA had provided, specifically in the world of Twitter, a free social networking microblogging service that allows registered members to broadcast short posts called tweets. We accomplish this through sentiment analysis and the spotting of trends within Twitter data. Furthermore, we follow a framework of study that allows simple and cost-effective analysis of discrete events of arbitrary nature.
Understanding plant community composition in agricultural wetlands: Context dependent effects and plant interactions

Question: What is the relative importance of resident native plant richness, resident functional group composition, soil N, soil P, and pasture-type in determining wetland invasion? Do nonnative richness, frequency, and biomass respond to the same abiotic and biotic variables? Location: MacArthur Agro-Ecology Research Center, south-central Florida, USA Methods: We measured native and non-native species richness and frequency in 15 1 m 2 plots / 40 wetlands across two different pasture-types, agronomically improved (IMP) and semi-natural (SNP). Biomass of both non-native and native plants was collected in five 0.25 m 2 plots/wetland, sorted to species, dried and weighed. Soil cores were collected from five points/wetland to analyze soil total N and P. Preliminary analyses showed that native C3 perennial grass (C3g) abundance was the only functional group related to non-native attributes. We used residual maximum likelihood (REML) to model non-native richness, frequency, and biomass as a function of native attributes, C3g abundance, N, P, and pasture-type. Effect sizes were used to determine the strength of the covariates in relation to one another. Non-metric multidimensional scaling was used to determine if there were different suites of non-natives among pasture-types. Results: In SNP wetlands non-native richness was negatively correlated to native richness and positively correlated to soil N while non-native frequency was positively associated with soil total P. In contrast, abiotic variables were unimportant in explaining non-native richness or abundance in IMP wetlands. However, non-native richness, frequency and biomass were all
