The Jim Sage volcanic suite (JSVS) exposed in the Jim Sage and Cotterel Mountains of southern Idaho (USA) consists of two volcanic members composed of ~240 km3 of Miocene rhyolite lavas separated by an interval of lacustrine sediments. It is capped by rheomorphic ignimbrite and as much as 100 m of basaltic lava flows probably derived from the central Snake River Plain (SRP) province to the north. The occurrence of volcanic vents in the JSVS links the lava flows to their local eruptive centers, while the adjacent Albion-Raft River-Grouse Creek metamorphic core complex exposes ~3000 km2 of once deep-seated rocks that offer constraints on the composition of the potential crustal sources of these rhyolites. U-Pb zircon ages from the rhyolite lavas of the JSVS range from 9.5 to 8.2 Ma. The Miocene basalt of the Cotterel Mountains has an 87Sr/86Sri composition of 0.7066-0.7075 and εNd(i) = -3.7, and the rhyolite lavas of the JSVS have 87Sr/86Sri = 0.7114-0.7135 and εNd(i) values that range from -6.7 to -7.1. Zircon from the rhyolites of the JSVS range in δ18Ozr (Vienna standard mean ocean water, VSMOW) from -0.5‰ to 5.7‰ and have εHf(i) values ranging from -0.8 to -6.8. Based on geochronology, whole-rock major elements, trace elements, isotopes (Sr and Nd), and in situ zircon O and Hf isotopic compositions, we infer that the JSVS is genetically related to the central SRP province. The eruption of the low-δ18O rhyolites of the JSVS, outside of the main topographic extent of the SRP province (without the large calderas inferred for the SRP rhyolites) implies that there might be an alternative mechanism for the formation of the low-δ18O signature other than the proposed assimilation of hydrothermally altered caldera blocks. One suggestion is that the north to south propagation of SRP-type low- δ18O rhyolitic melt along the Albion fault led to off-axis magmatism. Another possibility is that there was prior and widespread (across a region wider than the SRP) hydrothermal alteration of the crust related to its earlier magmatic and faulting history. The eruption of SRP-type lavas in the hanging wall of an evolving metamorphic core complex helps us outline the role of the SRP magmatic province in the extensional evolution of the northeastern Basin and Range. The lavas of the JSVS imply the addition of basalt, related to the SRP hotspot, to the crust beneath the Raft River Basin that provided a heat source for crustal melting and weakening of the deep crust; this led to a vertical component of crustal flow and doming during extension, after the eruption of the 9.5-8.2 Ma JSVS rhyolites. This younger than 8.2 Ma component of vertical motion during faulting of the Miocene stratified sequence of the Raft River Basin and the rotation of the Albion fault to shallower angles collectively resulted in the subhorizontal detachment structure imaged seismically beneath the Raft River Basin.

The Archean nucleus of Laurentia, the Superior province, formed between 2.7 and 2.6 Ga. There is little record of sediment deposition on the craton for 100 m.yr. until deposition of the Huronian clastic sedimentary rocks (4-12 km thick) began along the south-central margin of the Superior province between 2.5 and 2.2 Ga. Huronian detrital zircon ages ( zircon SHRIMP 207Pbx/206Pbx np266 ages from six samples) are dominantly 2.6-2.7 Ga, with a small population aged 3.0-3.5 Ga in the middle of the Huron section. The mainly younger, and western, Animikie basin (6-12 km thick; 2.21-0.8 Ga) contains a wide range of nearshore and deep-water clastic rocks, including banded iron formations and the 1.85 Ga Sudbury "impactite" deposits with overlying turbidites. Animikie detrital zircon ages (np724 laser ablation ICP-MS 207Pbx/206Pbx zircon ages from 10 samples) contain a complex spectrum, with ages ranging from 1.8 to 3.8 Ga: the basal Chocolay (Denham, East Branch Arkose) samples contain zircons ranging in age from 2.1 to 3.7 Ga, with a dominant population at ~2.6 Ga; the basal Animikie (Menominee) quartzites contain zircons with ages between 2.1 and 3.8 Ga, with peaks variably at 2.1, 2.3, 2.6, and 3.0 Ga; the upper Animikie (Baraga) turbidites contain zircons with ages between 1.8 and 3.6 Ga, with a dominant peak at 1.85 Ga. The Huron and Animikie basins were intensely deformed by Penokean orogenic (1.85 Ga) accretion from the south. Deposition into the Huron basin was from the north and west for 200 m.yr.; then the depocenter shifted to the west at ~2.2 Ga, with the Animikie basin receiving clastic debris from all directions, including from terranes (e.g., Marshfield and the Wisconsin Magmatic Terrane) approaching from the south. Combined Huron and Animikie detrital zircon results record a migrating eastto- west depocenter, perhaps in conjunction with the dynamics of the central Marathon large igneous province mantle plume and dike swarm (~2.07 Ga), over a period of 500 m.yr.

The constraints and the vast solution space of operational research optimization problems make them hard to cope with. However, Computational Intelligence, and especially Nature-Inspired Algorithms, has been a useful tool to tackle hard and large space optimization problems. In this paper, a very consistent and effective hybrid optimization scheme to tackle cardinality constrained portfolio optimization problems is presented. This scheme consists of two nature-inspired algorithms, i.e. Sonar Inspired Optimization algorithm and Genetic Algorithm. Also, the incorporation of heuristic information, i.e. an expert's knowledge, etc., to the overall performance of the hybrid scheme is tested and compared to previous studies. More specifically, under the framework of a financial portfolio optimization problem, the heuristic information-enhanced hybrid scheme manages to reach a new optimal solution. Additionally, a comparison of the proposed hybrid scheme with other hybrid schemes applied to the same problem with the same data is performed. [ABSTRACT FROM AUTHOR]

Increasing integration of renewable energy sources, like solar photovoltaic (PV), necessitates the development of power forecasting tools to predict power fluctuations caused by weather. With trustworthy and accurate solar power forecasting models, grid operators could easily determine when other dispatchable sources of backup power may be needed to account for fluctuations in PV power plants. Additionally, PV customers and designers would feel secure knowing how much energy to expect from their PV systems on an hourly, daily, monthly, or yearly basis. The PROGNOSIS project, based at the Cyprus University of Technology, is developing a tool for intra-hour solar irradiance forecasting. This article presents the design, training, and testing of a single-layer long-short-term-memory (LSTM) artificial neural network for intra-hour power forecasting of a single PV system in Cyprus. Four years of PV data were used for training and testing the model (80% for training and 20% for testing). With a normalized root mean squared error (nRMSE) of 10.7%, the single-layer network performed similarly to a more complex 5-layer LSTM network trained and tested using the same data. Overall, these results suggest that simple LSTM networks can be just as effective as more complicated ones. [ABSTRACT FROM AUTHOR]

Heart failure (HF) with mid-range ejection fraction (HFmrEF) is a newly suggested entity in HF. Since it has been inadequately addressed, there is an urgent need to determine the profile of HFmrEF patients and the optimal approach to their management. The present study aimed to assess the long-term clinical outcomes of hypertensive patients with HFmrEF and the impact of blood pressure (BP) on their mortality and cardiovascular outcome. We performed a retrospective observational study that included 121 hypertensive patients with HFmrEF and 149 hypertensives with heart failure and preserved ejection fraction (HFpEF). The median follow-up was 84 months (22-122). Our analysis did not reveal any statistically significant difference between the two groups in total mortality (P = 0.34) or cardiovascular mortality (P = 0.54). The total mean survival time was 102.9 months (100.5-110.1), while the mean survival time was 105.3 months (80.4-90.2) in HFpEF and 97.6 months (92.7-102.6) in HFmrEF. An office systolic BP > 139 mm Hg and diastolic BP > 89 mm Hg were significantly associated with both all-cause mortality (P = 0.02 and P = 0.013, respectively) and cardiovascular mortality (P = 0.02 for both). In HFpEF patients, no significant association was found between outcome and office BP. HFpEF and HFmrEF have similar long-term outcomes. Suboptimal BP levels are a significant risk factor for an adverse outcome in HFmrEF. Our results emphasize the importance of good BP control in order to achieve better outcomes in hypertensives with impaired EF and HF symptomatology. [ABSTRACT FROM AUTHOR]

Although more than 800,000 displaced people arrived in Greece by sea in 2015, fewer than 5 percent applied for asylum in this first country of arrival. Instead, they either traveled northward informally or remained in Greece in legal limbo. The resultant chaotic conditions deprived many refugees of the benefits of asylum and formal relocation procedures, and also reduced the Greek government's popularity among natives. We argue that governments, regional and international organizations, and aid groups can undermine compliance with their own policies by mishandling information dissemination. Common crisis-management tools—such as frequent policy changes, information dissemination limits, and ad-hoc policy implementation—can easily backfire. Information mismanagement can lead people to develop deep distrust in government and aid organizations, and instead turn to informal brokers like smugglers. To assess our theory, we draw on over 80 discussions with migrants and refugees in Greece, on 25 semistructured interviews with aid workers and government officials, and on weekly rumor correction newsletters produced by the nongovernmental organization Internews. We conclude that governments must prioritize effective communication and policy transparency, especially in crisis contexts. [ABSTRACT FROM AUTHOR]

Since the dawn of the new millennium and even earlier, a coordinated effort has been underway to expand the World Wide Web into a machine-readable web of data known as the Semantic Web. The field of art and culture has been one of the most eager to integrate with the Semantic Web, since metadata, data structures, linked-data, e.g., the Getty vocabularies project and the Europeana LOD initiative—and other building blocks of this web of data are considered essential in cataloging and disseminating art and culture-related content. However, art is a constantly evolving entity and as such it is the subject of a vast number of online media outlets and journalist blogs and websites. During the course of the present study the researchers collected information about how integrated the media outlets that diffuse art and culture-related content and news are to the Semantic Web. The study uses quantitative metrics to evaluate a website's adherence to Semantic Web standards and it proceeds to draw conclusions regarding how that integration affects their popularity in the modern competitive landscape of the Web.

Since 2015, a large number of migrants (refugees and asylum seekers) from the Middle East, Asia, and Africa have arrived in Greece and continued their onward journey to western European countries where they settled. As various European Union (EU) countries have later blocked the flow of migrants from Greece to their final destination, thousands of them have been trapped in Greece, confined in overcrowded, temporary camps (known as "hot spots") and awaiting the processing of their asylum application. The current article examines the response of the Greek educational institutes (primary, secondary and tertiary levels) to the recent migrant influx, with ultimate goals to integrate, educate, and assist them. The number of refugees and asylum seekers living in Greece is estimated to be 58,000 (2018 data) with 22,500 children among them. Their schooling inclusion follows the plan 111, "Refugee Education Host Structures (REHSs)", as initiated by the Greek Ministry of Education in 2017. Students' leakage range is still high (10–40% at elementary school and 45–56% at high School). The disruption in their life results in the lack of regular attendance. Greek universities responded to the challenge of the refugee influx, especially the University of the Aegean (UAeg), which is located on the eastern Mediterranean migration route. The UAeg's response plan focuses on four areas: (a) to provide education to refugees; (b) to conduct research on the refugee phenomenon and migration processes; (c) to increase local citizens' awareness and improve social inclusion toward the migrants; and (d) to develop technologies to improve daily life in the refugee camps. These actions are significant toward the social inclusion and cohesion of refugees and the further improvement of their daily life. [ABSTRACT FROM AUTHOR]
