Rilievo e ricostruzione virtuale del Ponte Sud di Hierapolis di Frigia (Turchia)
Authors: Di Giacomo Giacomo , Limoncelli Massimo , Scardozzi Giuseppe 
Published: November 2015

<p>The paper concerns the topographical survey and the 3D reconstruction of a Roman bridge-aqueduct located immediately to the south of Hierapolis in Phrygia (south-western Turkey), along the ancient route directed to Colosse and the internal Anatolia; only its southern abutment and scarce remains of the northern one are preserved. It is in a very difficult location, inside the narrow and deep valley, and it was never studied before. During the 2011 field work campaign of the Italian Archaeological Mission, it was surveyed using a high precision differential GPS system (for the plan documentation and its positioning in the digital archaeological map of Hierapolis) and through a Motorized Robotic Total Station (for the documentation of the elevation and the creation of a 3D model of the southern side) with the aim of its virtual reconstruction.</p>

<p>Both on-site data-collection surveying technologies and the new possibilities of graphical and cartographical techniques, currently allow us to obtain products that far exceed the traditional topographic maps and detailed representations of the graphical drawings that document the archaeological sites.<br />This paper aims to show, through concrete examples, the advantages of combining the use of different state-of-the-art technologies to achieve a graphic documentation in line with current demands, which logically are increasing due to technological advances as well.<br />In this way, different instruments have been used to carry out the field work: a high-definition laser scanner for massive data capture, a RTK GPS for the georeferencing the base points of the surveying, a laser total station to reference the point clouds to the UTM system and UAV devices, with a high resolution digital camera on board, to capture textures. In the office work state-of-the-art software has been used in order to perform the registration of different scans, application of textures to the point cloud, surface modelling and obtain various graphic products.<br />The quality of the products obtained enables archaeologists to achieve an archaeological analysis much more comprehensive than using a traditional documentation; last but not least, it is the speed of the fieldwork performance, the true potential of new technologies in the archaeological sites.</p>

<p>The assessment of the timelessness of Architecture as work of art, together with his temporality as a result of their evolution along time, results from our<br />contemporary culture. Nowadays we appreciate the material essence in architectural heritage, the processes that erected, transformed and even destroyed, and its role as bearer of meaning. Its consideration as a "document" is a value that determines and molds its conservation, research, management and spreading, requiring strategies and tools. This paper sets out in this forum, some observations that we consider essential about the resources, tools and methodological approaches that our group has been applying in its work.</p>

<p>In recent years, the continuing development of architectural survey techniques based on point clouds captured by laser scanning has revolutionized the field of<br />documentation prior to intervention, management or research in heritage. No clutch, affirming that these techniques have displaced others, such as photogrammetry, that have played an important role in the field of architectural survey, is a precipitated guess. Among other advantages, photogrammetry offers the ability to capture missing realities, lacking the materialness required for the use of laser scanner. In that vein, this paper describes the work of photogrammetric survey, location of parts and graphical anaparástasis of prior state to collapse of the Keep of the Castle of Constantine.</p>

The Euro Zone Economic Crisis and Sub-Saharan Africa’s Real Economy: Analysis and the Way Forward
Authors: Chea Ashford C. 
Published: November 2015

<p class="ber"><span lang="EN-GB">The purpose of the paper was to investigate if there were some negative impact of the euro zone economic crisis on sub-Saharan Africa’s (SSA) real economy. The evidence revealed that the euro zone crisis had affected sub-Saharan Africa economy in terms of trade, development assistance, and remittance. The conclusion derived from the evidence is that SSA’s economic growth was negatively affected slightly. This was due to prudential policies implemented by SSA policy-makers. The article begins with the historical background of the euro zone economic crisis and its root causes. It then provides an analysis of the transmission channels of the crisis and its impact on SSA’s economies. This is followed by a discussion of the policy responses to the crisis by SSA’s policy-makers. The paper concludes with an analysis of SSA’s recent economic performance and the way forward for long term growth and sustainable development. </span></p>
Formation of hybrid hafnium oxide by applying sacrifacial silicon film
Authors: Lin Chiung-Wei , Zheng Bo-Shen , Huang Jing-Wei 
Published: November 2015

Abstract
In the fabrication of hafnium oxide (HfO2)-based metal–insulator–semiconductor (MIS) devices, a sacrificial amorphous silicon (a-Si) film was used as silicon source for facilitating the formation of hafnium silicate (Hf-silicate; HfSiO) between HfO2 and crystallized Si (c-Si). HfSiO can assist in changing the phase of the HfO2 film into the tetragonal phase and achieve high dielectric constant. The combination of HfSiO and HfO2 was named as “Hybrid HfO2”. When this Hybrid HfO2 insulator was applied to MIS devices, it can form a good insulator/semiconductor interface with c-Si. Hybrid HfO2 cannot only suppress the leakage current but also show high dielectric strength. The Hybrid HfO2 film in this work exhibited a high dielectric constant of 25.5 and a high dielectric strength of 17.9 MV/cm.
Visualizing tephra deposits and sedimentary processes in the marine environment: The potential of X‐ray microtomography

Published: November 2015

AbstractLocalized tephra deposition in marine sequences is the product of many complex primary and secondary depositional processes. These can significantly influence the potential applicability of tephra deposits as isochronous marker horizons and current techniques, used in isolation, may be insufficient to fully unravel these processes. Here we demonstrate the innovative application of X‐ray microtomography (µCT) to successfully identify tephra deposits preserved within marine sediments and use these parameters to reconstruct their internal three‐dimensional structure. Three‐dimensional visualizations and animations of tephra dispersal in the sediment permit a more thorough assessment of postdepositional processes revealing a number of complex microsedimentological features that are not revealed by conventional methods. These features include bioturbation burrows and horizontally discontinuous tephra packages, which have important ramifications for the stratigraphic placement of the isochron in a sedimentary sequence. Our results demonstrate the potential for utilizing rigorous two and three‐dimensional microsedimentological analysis of the ichnofabric to enhance and support the use of tephra deposits as isochronous marker horizons and to identify the stratigraphic position that best reflects the primary fallout of ash. The application also provides an exceptional insight into the style and rate of sedimentation processes and permits an assessment of the stratigraphic integrity of a tephra deposit. We discuss the possibility of applying these µCT methods to the identification of cryptotephras within various paleoclimatic sequences and to enhance our understanding of marine sedimentation processes.
Submarine and subaerial lavas in the West Antarctic Rift System: Temporal record of shifting magma source components from the lithosphere and asthenosphere
Authors: Aviado Kimberly B. , Rilling‐Hall Sarah , Bryce Julia G. , Mukasa Samuel B. 
Published: November 2015

AbstractThe petrogenesis of Cenozoic alkaline magmas in the West Antarctic Rift System (WARS) remains controversial, with competing models highlighting the roles of decompression melting due to passive rifting, active plume upwelling in the asthenosphere, and flux melting of a lithospheric mantle metasomatized by subduction. In this study, seamounts sampled in the Terror Rift region of the Ross Sea provide the first geochemical information from submarine lavas in the Ross Embayment in order to evaluate melting models. Together with subaerial samples from Franklin Island, Beaufort Island, and Mt. Melbourne in Northern Victoria Land (NVL), these Ross Sea lavas exhibit ocean island basalt (OIB)‐like trace element signatures and isotopic affinities for the C or FOZO mantle endmember. Major‐oxide compositions are consistent with the presence of multiple recycled lithologies in the mantle source region(s), including pyroxenite and volatile‐rich lithologies such as amphibole‐bearing, metasomatized peridotite. We interpret these observations as evidence that ongoing tectonomagmatic activity in the WARS is facilitated by melting of subduction‐modified mantle generated during 550–100 Ma subduction along the paleo‐Pacific margin of Gondwana. Following ingrowth of radiogenic daughter isotopes in high‐µ (U/Pb) domains, Cenozoic extension triggered decompression melting of easily fusible, hydrated metasomes. This multistage magma generation model attempts to reconcile geochemical observations with increasing geophysical evidence that the broad seismic low‐velocity anomaly imaged beneath West Antarctica and most of the Southern Ocean may be in part a compositional structure inherited from previous active margin tectonics.
Diking‐induced moderate‐magnitude earthquakes on a youthful rift border fault: The 2002 Nyiragongo‐Kalehe sequence, D.R. Congo
Authors: Wauthier C. , Smets B. , Keir D. 
Published: November 2015

AbstractOn 24 October 2002, Mw6.2 earthquake occurred in the central part of the Lake Kivu basin, Western Branch of the East African Rift. This is the largest event recorded in the Lake Kivu area since 1900. An integrated analysis of radar interferometry (InSAR), seismic and geological data, demonstrates that the earthquake occurred due to normal‐slip motion on a major preexisting east‐dipping rift border fault. A Coulomb stress analysis suggests that diking events, such as the January 2002 dike intrusion, could promote faulting on the western border faults of the rift in the central part of Lake Kivu. We thus interpret that dike‐induced stress changes can cause moderate to large‐magnitude earthquakes on major border faults during continental rifting. Continental extension processes appear complex in the Lake Kivu basin, requiring the use of a hybrid model of strain accommodation and partitioning in the East African Rift.
Geochemistry, thermal evolution, and cryovolcanism on Ceres with a muddy ice mantle
Authors: Neveu Marc , Desch Steven J. 
Published: November 2015

AbstractWe present a model of the internal evolution of Ceres consistent with pre‐Dawn observations and preliminary data returned by Dawn. We assume that Ceres accreted ice and both micron‐ and millimeter‐sized rock particles and that micron‐sized fines stayed suspended in liquid during differentiation. We conclude that aqueously altered grains were emplaced on Ceres's surface during the first tens of megayears of its evolution. Our geochemical simulations suggest that Ceres's unusual surface mineralogy is consistent with aqueous alteration of CM material, possibly by NH3‐bearing fluid. Thermal evolution simulations including insulating fines yield present‐day liquid at depth if Ceres has a small core or no core at all; otherwise, they yield temperatures at the core‐mantle boundary of 240–250 K, just warm enough for chloride brines to persist and be freezing today. We hypothesize that ongoing freezing may overpressurize liquid or briny reservoirs, driving cryovolcanic outflow whose surface expression may have been observed by Dawn at Ceres's “bright spots.” These outflows may contribute to the water vapor being produced at Ceres.
Ancient and recent clay formation on Mars as revealed from a global survey of hydrous minerals in crater central peaks
Authors: Sun Vivian Z. , Milliken Ralph E. 
Published: November 2015

AbstractClay minerals on Mars have commonly been interpreted as the remnants of pervasive water‐rock interaction during the Noachian period (>3.7 Ga). This history has been partly inferred by observations of clays in central peaks of impact craters, which often are presumed uplifted from depth. However, combined mineralogical and morphological analyses of individual craters have shown that some central peak clays may represent post‐impact, possibly authigenic processes. Here we present a global survey of 633 central peaks to assess their hydrous minerals and the prevalence of uplifted, detrital, and authigenic clays. Central peak regions are examined using high‐resolution Compact Reconnaissance Imaging Spectrometer for Mars and High Resolution Imaging Science Experiment data to identify hydrous minerals and place their detections in a stratigraphic and geologic context. We find that many occurrences of Fe/Mg clays and hydrated silica are associated with potential impact melt deposits. Over 35% of central peak clays are not associated with uplifted rocks; thus, caution must be used when inferring deeper crustal compositions from surface mineralogy of central peaks. Uplifted clay‐bearing rocks suggest the Martian crust hosts clays to depths of at least 7 km. We also observe evidence for increasing chloritization with depth, implying the presence of fluids in the upper portions of the crust. Our observations are consistent with widespread Noachian/Early Hesperian clay formation, but a number of central peak clays are also suggestive of clay formation during the Amazonian. These results broadly support current paradigms of Mars' aqueous history while adding insight to global crustal and diagenetic processes associated with clay mineral formation and stability.
Seasonal variation of Martian middle atmosphere tides observed by the Mars Climate Sounder
Authors: Wu Zhaopeng , Li Tao , Dou Xiankang 
Published: November 2015

AbstractThe increased local time coverage retrieved from the Mars Climate Sounder on board the Mars Reconnaissance Orbiter enables the direct extraction of thermal tides in the Mars middle atmosphere. Using temperature profiles from Mars years 30 to 32, we studied the latitudinal and seasonal variations in the tides and stationary planetary waves with zonal wave numbers s = 1–3. The amplitude of the migrating diurnal tide exhibits strong semiannual variations in both the equatorial region and the middle latitudes of Southern Hemisphere. The migrating semidiurnal tide (SW2) shows clear semiannual variations in the equatorial region and the middle latitudes of Northern Hemisphere but an annual variation in the Southern Hemisphere. The spatial and temporal correlations between the SW2 amplitude and the density‐scaled opacity of both the water ice and dust in the equatorial region may provide a possible explanation for the tidal forcing of SW2. Three Kelvin modes with zonal wave numbers 1–3 (DE1–DE3) have significant seasonal variations in the equatorial region. DE1 appears to have a semiannual variation, whereas DE2 and DE3 have clear annual variations. Herein, for the first time, we have extracted the westward propagating diurnal tide with s = 2 and 3 and semidiurnal tide with s = 1 in the Mars middle atmosphere using observational data. All three waves have asymmetric latitudinal distributions, which should correspond to their possible excitation source, i.e., nonlinear interactions between stationary planetary waves and migrating tides.
The effect of regional groundwater on carbon dioxide and methane emissions from a lowland rainforest stream in Costa Rica
Authors: Oviedo‐Vargas Diana , Genereux David P. , Dierick Diego , Oberbauer Steven F. 
Published: November 2015

AbstractIn the tropical rainforest at La Selva Biological Station in Costa Rica, regional bedrock groundwater high in dissolved carbon discharges into some streams and wetlands, with the potential for multiple cascading effects on ecosystem carbon pools and fluxes. We investigated carbon dioxide (CO2) and methane (CH4) degassing from two streams at La Selva: the Arboleda, where approximately one third of the streamflow is from regional groundwater, and the Taconazo, fed exclusively by local groundwater recharged within the catchment. The regional groundwater inflow to the Arboleda had no measurable effect on stream gas exchange velocity, dissolved CH4 concentration, or CH4 emissions but significantly increased stream CO2 concentration and degassing. CO2 evasion from the reach of the Arboleda receiving regional groundwater (lower Arboleda) averaged 5.5 mol C m−2 d−1, ~7.5 times higher than the average (0.7 mol C m−2 d−1) from the stream reaches with no regional groundwater inflow (the Taconazo and upper Arboleda). Carbon emissions from both streams were dominated by CO2; CH4 accounted for only 0.06–1.70% of the total (average of both streams: 5 × 10−3 mol C m−2 d−1). Annual stream degassing fluxes normalized by watershed area were 48 and 299 g C m−2 for the Taconazo and Arboleda, respectively. CO2 degassing from the Arboleda is a significant carbon flux, similar in magnitude to the average net ecosystem exchange estimated by eddy covariance. Examining the effects of catchment connections to underlying hydrogeological systems can help avoid overestimation of ecosystem respiration and advance our understanding of carbon source/sink status and overall terrestrial ecosystem carbon budgets.
Social Contagion in Competitors Versus Cooperators
Authors: Park Su Hyoun , Son Lisa K. , Kim Min‐Shik 
Published: November 2015

SummaryThe current study examined social contagion—or the spreading of memories from individual to individual—in two different social contexts: Competition and Cooperation. Participants were provided with words (Experiments 1A and 1B) or scenes (Experiment 2) to study. After study, participants were randomly divided: Half were given a competitive context, and the other half, a cooperative context. Then, in the paired recall phase, each participant took turns with a confederate partner in recalling the previously studied items. On a subsequent test, participants had to report the items that were recalled on the pair recall phase, in addition to who had recalled that item. The results showed that competitors, as compared with cooperators, were more likely to focus on other people's memories, and surprisingly, the same difference obtained for false memories. Essentially, people who are primed with a competitive context were more easily ‘infected’ by memories, true or false. Copyright © 2015 John Wiley & Sons, Ltd.
