    Papanikolau, N.

    Welcome by the Mayor of Valtetsi Mr. Chairman Ladies and Gentlemen The municipality of Valtetsi welcomes you and wishes success in your work. Arcadia is both a historical and modern region. Moreover, as a name it remained in the western culture recalling a harmonious and peaceful dream, a lost and desirable situation where the human being lived in balance with nature, a region where the person did not feel yet uprooted. For thousands of years the poetic voices retained vivid this eternal bucolic call of simplicity and accessible happiness. Gazing the starlit sky we will always see Kallisto, the daughter of Lykaona, king of Arcadia and her son Arcadian as they were both transformed in to the constellations Major and Minor Ursus because of the erotic libido of Jupiter and the jealousy of Hera. And we will always remember Centaurus Cheirona, the great schoolteacher of ancient heroes, who was the first to name the constellations according to mythology. Finally we would like to thank the patriot Mr. T. Tzioumi who returns to his beautiful village in Arcadia just like Antaios did. In the geographic place that inspired the arcadian ideal, such activities recall in the limelight Arcadia as was dreamed by Europe. Mr. Chairman, ladies and gentlemen, success in your scientific work. The Municipality of Valtetsi and I myself will be always next to you so that your stay at Arcadia will always remain vivid in your memory. Thank you. Nikos Papanikolaou Mayor of Valtetsi

  5. Evolution of a Quaternary peralkaline volcano: Mayor Island, New Zealand

    USGS Publications Warehouse

    Houghton, B.F.; Weaver, S.D.; Wilson, C.J.N.; Lanphere, M.A.

    1992-01-01

    Mayor Island is a Holocene pantelleritic volcano showing a wide range of dispersive power and eruptive intensity despite a very limited range in magma composition of only 2% SiO2. The primary controls on this range appear to have been the magmatic gas content on eruption and a varying involvement of basaltic magma, rather than major-element chemistry of the rhyolites. The ca. 130 ka subaerial history of the volcano contains portions of three geochemical cycles with abrupt changes in trace-element chemistry following episodes of caldera collapse. The uniform major-element chemistry of the magma may relate to a fine balance between rates of eruption and supply and the higher density of the more evolved (Ferich) magmas which could be tapped only after caldera-forming events had removed significant volumes of less evolved but lighter magma. ?? 1992.

  5. The role of a keystone fault in triggering the complex El Mayor-Cucapah earthquake rupture

    NASA Astrophysics Data System (ADS)

    Fletcher, John M.; Oskin, Michael E.; Teran, Orlando J.

    2016-04-01

    The 2010 Mw 7.2 El Mayor-Cucapah earthquake in Baja California, Mexico activated slip on multiple faults of diverse orientations, which is commonly the case for large earthquakes. The critical stress level for fault failure depends on fault orientation and is lowest for optimally oriented faults positioned approximately 30¬į to the greatest principal compressive stress. Yet, misoriented faults whose positioning is not conducive to rupture are also common. Here we use stress inversions of surface displacement and seismic data to show that the El Mayor-Cucapah earthquake initiated on a fault that, owing to its orientation, was among those that required the greatest stress for failure. Although other optimally oriented faults must have reached critical stress earlier in the interseismic period, Coulomb stress modelling shows that slip on these faults was initially muted because they were pinned, held in place by misoriented faults that helped regulate their slip. In this way, faults of diverse orientations could be maintained at critical stress without destabilizing the network. We propose that regional stress build-up continues until a misoriented keystone fault reaches its threshold and its failure then spreads spontaneously across the network in a large earthquake. Our keystone fault hypothesis explains seismogenic failure of severely misoriented faults such as the San Andreas fault and the entire class of low-angle normal faults.

  8. Did stresses from the Cerro Prieto Geothermal Field influence the El Mayor-Cucapah rupture sequence?

    NASA Astrophysics Data System (ADS)

    Trugman, Daniel T.; Borsa, Adrian A.; Sandwell, David T.

    2014-12-01

    The Mw 7.2 El Mayor-Cucapah (EMC) earthquake ruptured a complex fault system in northern Baja California that was previously considered inactive. The Cerro Prieto Geothermal Field (CPGF), site of the world's second largest geothermal power plant, is located approximately 15 km to the northeast of the EMC hypocenter. We investigate whether anthropogenic fluid extraction at the CPGF caused a significant perturbation to the stress field in the EMC rupture zone. We use Advanced Land Observing Satellite interferometric synthetic aperture radar data to develop a laterally heterogeneous model of fluid extraction at the CPGF and estimate that this extraction generates positive Coulomb stressing rates of order 15 kPa/yr near the EMC hypocenter, a value which exceeds the local tectonic stressing rate. Although we cannot definitively conclude that production at the CPGF triggered the EMC earthquake, its influence on the local stress field is substantial and should not be neglected in local seismic hazard assessments.

    2012-02-10

    Large [moment magnitude (M(w)) ‚Č• 7] continental earthquakes often generate complex, multifault ruptures linked by enigmatic zones of distributed deformation. Here, we report the collection and results of a high-resolution (‚Č•nine returns per square meter) airborne light detection and ranging (LIDAR) topographic survey of the 2010 M(w) 7.2 El Mayor-Cucapah earthquake that produced a 120-kilometer-long multifault rupture through northernmost Baja California, Mexico. This differential LIDAR survey completely captures an earthquake surface rupture in a sparsely vegetated region with pre-earthquake lower-resolution (5-meter-pixel) LIDAR data. The postevent survey reveals numerous surface ruptures, including previously undocumented blind faults within thick sediments of the Colorado River delta. Differential elevation changes show distributed, kilometer-scale bending strains as large as ~10(3) microstrains in response to slip along discontinuous faults cutting crystalline bedrock of the Sierra Cucapah.

The sources, including surface explosions, large bolides, mining events and a space shuttle, combined with the very high density of recording sites, have contributed to an understanding of the broad range of infrasound signals that can be recorded at seismic sensors. One finding from these studies is that infrasound propagation modeling using both ray theory and linear full-waveform synthesis methods fails to predict the full range of arrivals observed at the recording sites. This failure reflects inaccuracies either in the atmospheric specifications - the wind and static sounds - that guide acoustic propagation, or in the assumptions used in linear propagation methods. The effect of nonlinearity on infrasound propagation modeling is investigated for the 7.2 El Mayor earthquake that occurred on 4 April, 2010. This event generated infrasound at frequencies of several Hertz that was recorded over 200 km away at sites to the north and west of the epicentral region, despite stratospheric winds that favor propagation in an eastward direction. The observations of higher frequency infrasound suggest non-linear steepening, either at stratospheric or thermospheric altitudes. The locations of the epicenter, aftershocks, and surface rupture suggest that the rupture had a spatial extent of roughly 75 km in length, i.e nearly a line source. We compute waveforms with and without the effects of nonlinearity from a line source for a wind and sound speed model relevant to the El Mayor rupture, and compare these to waveforms recorded for this event.

    Cities and Mayors are increasingly being recognized as important in shaping social policy and improving social well-being. And municipal food policies are increasingly important as a tool to reduce food insecurity and prevent diet-related chronic diseases. Thus city governments have a unique ability to improve local food environments. To realize this potential for improving urban food environments, nutrition advocates will need to find innovative approaches for influencing municipal food policy. This paper examines Mayoral elections as a vehicle to advance food policy. To explore this strategy, Mayoral elections in two cities, New York City (NYC) and London, during two recent cycles were compared. To gather evidence multiple sources were used including campaign documents, media and opinion polls as well as the authors' own observations as food policy observers and participants in the two cities. Mayoral governance differs between NYC and London, with the Mayor in NYC having greater powers of management and administration, whilst the London Mayor has a more strategic role and may need to also use 'influence'. Food policy and related issues did not feature strongly in the first election cycles in either city. However by the 2012 and 2013 elections food issues were definitely 'on the table' and featured in main candidates' campaign literature. These latter elections also saw the importance of food advocates coming together to form common alliances and place food issues higher on the municipal agenda. In this way, food policy has become part of the election dialogue in both cities and candidates are expected to consider food policy issues. This analysis leads to make observations which could guide advocates as to how to use Mayoral elections to raise policy objectives for the benefit of public health. PMID:25834929

  12. Mechanisms of Postseismic Deformation Following the 2010 M=7.2 El Mayor-Cucapah Earthquake

    Aseismic deformation processes such as fault creep, viscous flow, and pore fluid motion influence the states of stress on fault zones, making them important in regional seismic hazard assessment. A large earthquake imparts stress changes to the surrounding medium that can accelerate these processes, producing transient surface deformation that can yield valuable information about them. The Salton Trough is an ideal site in which to use this method to study the rheological structure of extensional environments: the extensional component of relative plate motion there has thinned the continental lithosphere and brought the asthenosphere up to within 45 km of the surface, while the transform component of relative motion produces large strike-slip earthquakes that impart large stress changes to this shallow asthenosphere. The most recent such earthquake, the 2010 M=7.2 El Mayor-Cucapah event, was the largest earthquake in this region since at least 1892 and occurred directly above shallow asthenosphere. Using the Wei et al [2011] slip model for the El Mayor-Cucapah event and the deformation modeling software RELAX, we simulate postseismic surface deformation resulting from afterslip and viscoelastic relaxation in a variety of hypothetical geometries, then compare these forward models to postseismic displacements observed in GPS data. We observe a broad pattern of westward postseismic displacement in the Peninsular Ranges that is consistent with linear Newtonian viscoelastic relaxation in a low-viscosity asthenosphere. Displacement timeseries in the eastern Imperial Valley suggest that a power-law rheology may also be present in at least the shallow Salton Trough asthenosphere. A systematic pattern of postseismic uplift in the Imperial Valley is also best explained by viscoelastic relaxation in the asthenosphere and/or mantle lithosphere. Near-field horizontal displacements in the Imperial Valley feature both a short-term decaying signal consistent with power-law viscoelastic relaxation or deep afterslip and a notable sustained signal consistent with Newtonian viscoelastic relaxation in the lower crust and/or mantle lithosphere. The best-fitting models feature complex, laterally heterogeneous assortments of many of these mechanisms, suggesting that high heat flow in the Salton Trough results in reduced viscosities in both the crust and upper mantle.

  13. Studies on bioflocculant production by a mixed culture of Methylobacterium sp. Obi and Actinobacterium sp. Mayor

    2013-01-01

    Background Bioflocculants effect the aggregation of suspended solutes in solutions thus, a viable alternative to inorganic poly-ionic and synthetic organic flocculants which are associated with deleterious health problems. Consequently, a consortium of two bacteria species were evaluated for optimized bioflocculant yield following the inadequacies of axenic cultures. Results 16S rDNA nucleotide sequencing and BLAST analysis of nucleotide sequences were used to identify the bacterial species, carbon and nitrogen sources optimally supporting bioflocculant production were assessed and the purified bioflocculant characterized. Nucleotide sequences showed 97% and 96% similarity to Methylobacterium sp. AKB-2008-KU9 and Methylobacterium sp. strain 440. The second isolate, likewise, showed 98% similarity to Actinobacterium OR-221. The sequences were deposited in GenBank as Methylobacterium sp. Obi [accession number HQ537130] and Actinobacterium sp. Mayor [accession number JF799090]. Flocculating activity of 95% was obtained in the presence of Ca2+ and heat-stability was exhibited with retention of above 70% activity at 100¬įC in 30¬†min. In addition, bioflocculant yield was about 8.203¬†g/l. A dose of 1¬†mg/ml of purified bioflocculant was optimal for the clarification of Kaolin suspension (100¬†ml) following Jar test. FTIR spectrum revealed the presence of carboxyl and hydroxyl functional groups amongst others. Conclusions The mixed culture produced bioflocculant with high flocculating activity and an improved yield. The efficiency observed with jar test may imply industrial applicability. PMID:23915393

  18. The Mayor of EarthCube: Cities as an Analogue for Governing Cyberinfrastructure

    NASA Astrophysics Data System (ADS)

    2012-12-01

    Historical development of national and global infrastructure follows common paths with common imperatives. The nascent development may be led a by champion, innovator, or incubating organization. Once the infrastructure reaches a tipping point and adoption spreads rapidly, the organization and governance evolves in concert. Ultimately, no wide-spread infrastructure (from canals to highways to the electric grid to radio/television, or the Internet) operates with a single overarching governing body. The NSF EarthCube initiative is a prototype implementation of cyberinfrastructure, using the broad geoscience community as the testbed. Governance for EarthCube is emulating the pattern of other infrastructure, which we argue is a system of systems that can be described by organized complexity, emergent systems, and non-linear thermodynamics. As we consider governance cyberinfrastructure in the geosciences, we might look to cities as analogs: cities provide services such as fire, police, water, and trash collection. Cities issue permits and often oversee zoning, but much of what defines cities is outside the direct control of city government. Businesses choose whether to locate there, where to operate, and what to build. Residents make similar decisions. State and federal agencies make decisions or impose criteria that greatly affect cities, without necessarily getting agreement from them. City government must thus operate at multiple levels - providing oversight and management of city services, interaction with residents, businesses, and visitors, and dealing with actions and decisions made by independent entities over which they have little or no control. Cities have a range of organizational and management models, ranging from city managers, councils, and weak to strong mayors, some elected directly, some chosen from councils. The range and complexity of governance issues in building, operating, and sustaining cyberinfrastructure in the geosciences and beyond, rival those of running a medium to large city. The range of organizational and management structures in meeting community needs and goals are also diverse and may embody a multi-faceted set of governing archetypes, best suited to carry out each of myriad functions. We envision cyberinfrastructure governance to be a community-driven enterprise empowered to carry out a dynamic set of functions, operating within a set of processes (comparable to a city charter) and guiding principles (constitution).

    Due to its location on a transtensional section of the Pacific-North American plate boundary, the Salton Trough is a region featuring large strike-slip earthquakes within a regime of shallow asthenosphere, high heat flow, and complex faulting, and so postseismic deformation there may feature enhanced viscoelastic relaxation and afterslip that is particularly detectable at the surface. The 2010 El Mayor-Cucapah earthquake was the largest shock in the Salton Trough since 1892 and occurred close to the US-Mexico border, and so the postseismic deformation recorded by the continuous GPS network of southern California provides an opportunity to study the rheology of this region. Three-year postseismic transients extracted from GPS displacement time-series show four key features: (1) 1-2 cm of cumulative uplift in the Imperial Valley and 1 cm of subsidence in the Peninsular Ranges, (2) relatively large cumulative horizontal displacements 150 km from the rupture in the Peninsular Ranges, (3) rapidly decaying horizontal displacement rates in the first few months after the earthquake in the Imperial Valley, and (4) sustained horizontal velocities, following the rapid early motions, that were still visibly ongoing 3 years after the earthquake. Kinematic inversions show that the cumulative 3-year postseismic displacement field can be well fit by afterslip on and below the coseismic rupture, though these solutions require afterslip with a total moment equivalent to at least a earthquake and higher slip magnitudes than those predicted by coseismic stress changes. Forward modeling shows that stress-driven afterslip and viscoelastic relaxation in various configurations within the lithosphere can reproduce the early and later horizontal velocities in the Imperial Valley, while Newtonian viscoelastic relaxation in the asthenosphere can reproduce the uplift in the Imperial Valley and the subsidence and large westward displacements in the Peninsular Ranges. We present two forward models of dynamically coupled deformation mechanisms that fit the postseismic transient well: a model combining afterslip in the lower crust, Newtonian viscoelastic relaxation in a localized zone in the lower crust beneath areas of high heat flow and geothermal activity, and Newtonian viscoelastic relaxation in the asthenosphere; and a second model that replaces the afterslip in the first model with viscoelastic relaxation with a stress-dependent viscosity in the mantle. The rheology of this high-heat-flow, high-strain-rate region may incorporate elements of both these models and may well be more complex than either of them.

    The Magnitude 7.2 El-Mayor/Cucapah earthquake the occurred in Mexico on April 4, 2012 was well instrumented with continuous GPS stations in California. Large Offsets were observed at the GPS stations as a result of deformation from the earthquake providing information about the co-seismic fault slip as well as fault slip from large aftershocks. Information can also be obtained from the position time series at each station.

  1. Mastering Slip Distributions by Minimizing Model Parameterization Errors: A Case Study with the 2010 Sierra El Mayor, Mexico Earthquake

    2010-12-01

    Inversions of coseismic slip distributions from geodetic observations provide important information about the spatial distribution and magnitude of slip that can be used in better understanding static stress changes, the nature of slip asperities, and relations of aftershocks to co- and post-seismic processes. A variety of errors, including incorrect fault geometry, improper or simplified rigidity structure, and noise are propagated into slip distributions leading to incorrect assumptions when using these models to drive further modeling. In this work, we explore the potential to understand model parameterization errors by constraining the model geometry through a variety of means. We use the 2010 April 4 Sierra El Mayor earthquake as a case study due to the abundance of geological and geodetic observations of the rupture and local faults. We begin by exploring very simple, planar fault geometries to demonstrate errors associated with oversimplification. We then use digitized fault traces from geologic maps and literature to demonstrate errors that may be propagated into the slip distributions by assuming an incorrect fault location or fault strand. We also use fault traces digitized from deformation maps derived through pixel tracking offsets in SAR scenes to derive a model geometry. This technique allows us the best constraint on the actual surface rupture location without going into the field, but does not necessarily provide strong constraints on the fault geometry at depth. We explore the potential modeling errors associated with deeper portions of the fault through the use of a synthetic scenario similar to the Sierra El Mayor earthquake. In addition to variable fault geometries, we also demonstrate how variable model dislocation sizes can allow for parameterization of complicated surface fault traces without introducing unresolved resolution at depth.

    Surface fracturing (triggered slip) occurred in the central Salton Trough and to the southwest, in the Yuha Desert area‚ÄĒall in association with the 4 April 2010 (M7.2) El Mayor-Cucapah earthquake and its aftershocks. Triggered slip in the central Salton Trough occurred on the ‚Äėfrequent movers‚Äô: the southern San Andreas, Coyote Creek, Superstition Hills, and Imperial Faults, all of which have slipped in previous moderate to large, local and regional earthquakes in the past five decades. Other faults in the central Salton Trough that also slipped in 2010 include the Wienert Fault (southeastern section of the Superstition Hills Fault), the Kalin Fault (in the Brawley Seismic Zone), and the Brawley Fault Zone; triggered slip had not been reported on these faults in the past. Geologic measures of slip on faults in the central Salton Trough ranged from 1 to 18 mm, and everywhere was located where previous primary (tectonic) or triggered slip has occurred. Triggered slip in the Yuha Desert area occurred along at least two dozen faults, only some of which were known before the 4 April 2010 El Mayor-Cucapah earthquake. From east to northwest, slip occurred in seven general areas; 1) in the Northern Centinela Fault Zone (newly named), 2) along unnamed faults south of Pinto Wash, 3) along the Yuha Fault (newly named), 4) along both east and west branches of the Laguna Salada Fault, 5) along the Yuha Well Fault Zone (newly revised name), 6) along the Ocotillo Fault (newly named), and 7) along the southeastern-most section of the Elsinore Fault. Faults that slipped in the Yuha Desert area include northwest-trending right-lateral faults, northeast-trending left-lateral faults, and north-south faults, some of which had dominantly vertical slip. Triggered slip along the Ocotillo and Elsinore Faults occurred only in association with the 14 June 2010 (M5.7) aftershock, which also initiated slip along other faults near the town of Ocotillo. Triggered slip on faults in the Yuha Desert area was most commonly less than 20 mm, but two significant exceptions are slip of about 50-60 mm on the Yuha Fault and of about 80 mm on the Ocotillo Fault. All triggered slips in the Yuha Desert area occurred along pre-existing faults, whether previously recognized or not.

    The Colorado River Delta region of southern Imperial Valley, California, and Mexicali Valley, Baja California, is a tectonically dynamic area characterized by numerous active faults and frequent large seismic events. Significant earthquakes that have been accompanied by surface fault rupture and/or soil liquefaction occurred in this region in 1892 (M7.1), 1915 (M6.3; M7.1), 1930 (M5.7), 1940 (M6.9), 1950 (M5.4), 1957 (M5.2), 1968 (6.5), 1979 (6.4), 1980 (M6.1), 1981 (M5.8), and 1987 (M6.2; M6.8). Following this trend, the M7.2 El Mayor-Cucapah earthquake of April 4, 2010, ruptured approximately 120 kilometers along several known faults in Baja California. Liquefaction caused by the M7.2 El Mayor-Cucapah earthquake was widespread throughout the southern Imperial Valley but concentrated in the southwest corner of the valley, southwest of the city centers of Calexico and El Centro where ground motions were highest. Although there are few strong motion recordings in the very western part of the area, the recordings that do exist indicate that ground motions were on the order of 0.3 to 0.6g where the majority of liquefaction occurrences were found. More distant liquefaction occurrences, at Fites Road southwest of Brawley and along Rosita Canal northwest of Holtville were triggered where ground motions were about 0.2 g. Damage to roads was associated mainly with liquefaction of sandy river deposits beneath bridge approach fills, and in some cases liquefaction within the fills. Liquefaction damage to canal and drain levees was not always accompanied by vented sand, but the nature of the damage leads the authors to infer that liquefaction was involved in the majority of observed cases. Liquefaction-related damage to several public facilities - Calexico Waste Water Treatment Plant, Fig Lagoon levee system, and Sunbeam Lake Dam in particular - appears to be extensive. The cost to repair these facilities to prevent future liquefaction damage will likely be prohibitive. As such, it is likely that liquefaction will recur at these facilities during the next large earthquake in this area.

    The realization of national climate change commitments, as agreed through international negotiations, requires local action. However, data is still insufficient to make accurate statements about the scale of urban emissions (UNHABITAT, 2011). The need of comparable emission inventories at city level, including smaller cities, is widely recognized to develop evidence-based policies accounting for the relation between emissions and institutional, socio-economic and demographic characteristics at city level. This paper presents a collection of harmonized greenhouse gases (GHG) emission inventories (the "CoM sample 2013") at municipal level directly computed by the cities and towns that participate in the EU Covenant of Mayors initiative. This is the mainstream European movement of local and regional authorities who voluntarily commit to reduce GHG emissions by 20 % or more by 2020. The "CoM sample 2013" (http://edgar.jrc.ec.europa.eu/com/data/index.php?SECURE=123, doi:10.2904/EDGARcom2013) has been carefully checked to ensure its internal consistency and its congruity with respect to internationally accepted guide values for emission factors. Overall, it provides valuable data for the analysis of the heterogeneity of final energy consumption and greenhouse gas emissions of cities.

    Among the many preserved sound artefacts deposited in the offerings of the Aztec Templo Mayor are a set of ten tubular duct flutes made from clay, dating Late Postclassic Mesoamerica, 1350-1521 AD. The aerophones are completely painted in blue, and characterized by: (1) a short mouthpiece; (2) a framed aperture; (3) a tube with four fingerholes; and (4) an applicated mask with features of the Aztec rain god Tlaloc, basically three rings and a standardized relief structure of two clouds. While all measurements follow the same pattern, one particular organological distinction was made, as five flutes show an exit hole in the middle ring of the mask and five flutes are stopped. Thus, five instruments sound considerably higher, apart from the minimal pitch deviation of each specimen. Both the tonal capacity of each flute and the acoustics of several flutes played simultaneously were recorded and measured. A series of remarkable interference effects could be produced, which were strongly related to the ritual complex reflected in the offering. Taking in consideration the Aztec concept of music, it could be supposed that they were perceived as a principle of the song, or proper voice of Tlaloc.

    We detect and precisely locate over 9500 aftershocks that occurred in the Yuha Desert region during a 2 month period following the 4 April 2010 Mw 7.2 El Mayor-Cucapah (EMC) earthquake. Events are relocated using a series of absolute and relative relocation procedures that include Hypoinverse, Velest, and hypoDD. Location errors are reduced to ~40 m horizontally and ~120 m vertically.Aftershock locations reveal a complex pattern of faulting with en echelon fault segments trending toward the northwest, approximately parallel to the North American-Pacific plate boundary and en echelon, conjugate features trending to the northeast. The relocated seismicity is highly correlated with published surface mapping of faults that experienced triggered surface slip in response to the EMC main shock. Aftershocks occurred between 2 km and 11 km depths, consistent with previous studies of seismogenic thickness in the region. Three-dimensional analysis reveals individual and intersecting fault planes that are limited in their along-strike length. These fault planes remain distinct structures at depth, indicative of conjugate faulting, and do not appear to coalesce onto a throughgoing fault segment. We observe a complex spatiotemporal migration of aftershocks, with seismicity that jumps between individual fault segments that are active for only a few days to weeks. Aftershock rates are roughly consistent with the expected earthquake production rates of Dieterich (1994). The conjugate pattern of faulting and nonuniform aftershock migration patterns suggest that strain in the Yuha Desert is being accommodated in a complex manner.

    Triggered slip in the Yuha Desert area occurred along more than two dozen faults, only some of which were recognized before the April 4, 2010, El Mayor-Cucapah earthquake. From east to northwest, slip occurred in seven general areas: (1) in the Northern Centinela Fault Zone (newly named), (2) along unnamed faults south of Pinto Wash, (3) along the Yuha Fault (newly named), (4) along both east and west branches of the Laguna Salada Fault, (5) along the Yuha Well Fault Zone (newly revised name) and related faults between it and the Yuha Fault, (6) along the Ocotillo Fault (newly named) and related faults to the north and south, and (7) along the southeasternmost section of the Elsinore Fault. Faults that slipped in the Yuha Desert area include northwest-trending right-lateral faults, northeast-trending left-lateral faults, and north-south faults, some of which had dominantly vertical offset. Triggered slip along the Ocotillo and Elsinore Faults appears to have occurred only in association with the June 14, 2010 (Mw5.7), aftershock. This aftershock also resulted in slip along other faults near the town of Ocotillo. Triggered offset on faults in the Yuha Desert area was mostly less than 20 mm, with three significant exceptions, including slip of about 50‚Äď60 mm on the Yuha Fault, 40 mm on a fault south of Pinto Wash, and about 85 mm on the Ocotillo Fault. All triggered slips in the Yuha Desert area occurred along preexisting faults, whether previously recognized or not.

    Virtual globes are becoming ubiquitous for visualizing the Earth and other planets. However, as earth scientists pursue methods to visually explore and interpret earth surface processes using sub-meter pixel resolution digital elevation models (DEM) and imagery data spanning large areas, limitations of the commonly used virtual globes have emerged. We developed Crusta as an alternative virtual globe that allows users to investigate such data by conducting interactive, real-time, virtual field mapping. Crusta represents the globe as a 30-sided polyhedron to avoid distortion, in particular, the singularities at the poles characteristic of other projections. Each side can be subdivided to an arbitrarily fine grid to accommodate DEM and image data of arbitrary resolution. A convenient pre-processing tool based on the GDAL library facilitates importing a number of data formats into the Crusta-specific multi-scale hierarchical format. We designed Crusta with a focus on dynamic, interactive exploration of data: vertical exaggeration, shading, color ramp application, and display, generation and editing of decorated vector lines are supported in real time, directly on the virtual 3D landscape. These powerful visualization and interaction capabilities enable fluid and intuitive exploration, assist discovery and interpretation, and provide detailed feature mapping. Currently, we are using Crusta to investigate LiDAR data collected after the 4 April 2010, Mw7.2 El Mayor-Cucapah earthquake in northern Mexico. We have generated a single dataset comprised of multiple layers of finer DEMs embedded in coarser ones: 1) tripod LiDAR covering about 2 km of the rupture zone at 3 cm/pixel; 2) aerial LiDAR covering almost the entire rupture zone (over 300 km2) at 50 cm/pixel; 3) ASTER 30 m/pixel over the California/Mexico border region; 4) NASA's BlueMarble Next Generation over the whole globe at about 500 km/pixel. The interactive capabilities of Crusta to visually explore this dataset and create accurate, high-quality 3D geologic maps of the fresh, meter-scale coseismic surface ruptures has potential to advance understanding of how earthquakes deform the Earth's surface.

    The 4 April 2010 Mw 7.2 El Mayor-Cucapah earthquake generated strong shaking that was recorded by over 200 strong motion instruments throughout northern Baja California and southern California. At longer periods (T > 2 sec), rupture directivity and basin response effects lead to amplified ground motions and extended shaking durations in the Imperial/Coachella, San Bernardino and Los Angeles regions. Using a suite of hypothetical finite-fault rupture models, we test the ability of long-period ground-motion simulations of scenario earthquakes to produce waveforms consistent with these recordings. The hypothetical ruptures are constructed using the methodology proposed by Graves and Pitarka (2010) and require, as inputs, only a general description of the fault location and geometry, event magnitude and hypocenter. For each rupture model, simulations are run for two Southern California Earthquake Center (SCEC) 3D community seismic velocity models (CVM-4m and CVM-H62). While the details of the motions vary across the simulations, the median levels match the observed peak ground velocities reasonably well with the standard deviation of the residuals generally within 50% of the median. For the non-basin regions, simulations with the CVM-H62 model perform significantly better than those of CVM-4m, which we attribute to the inclusion of the Tape et al. (2009) tomographic updates within the background crustal velocity structure of CVM-H62. Within the greater Los Angeles region, the CVM-4m model generally matches the level of observed motions whereas the CVM-H62 model over-predicts the motions in the southernmost portion of the basin. Animations of the simulated wave fields demonstrate this over-prediction is created by the sharp impedance contrast along the southern margin of the Los Angeles basin in the CVM-H62 model. For both seismic velocity models, the variance in the peak velocity residuals is lowest for a rupture that has significant shallow slip (less than 5 km depth), whereas the variance in the residuals is greatest for ruptures with large asperities below 10 km depth. These results are consistent with recent source inversion studies indicating this earthquake was dominated by shallow (less than 10 km depth) moment release (e.g., Wei et al, 2010).

  13. Timing and controls on late Quaternary landscape development along the eastern Sierra El Mayor range front in northern Baja California, Mexico

    The Sierra El Mayor-Sierra Cucap√° mountain range in northern Baja separates the Colorado River delta from the Laguna Salada Basin and is important in terms of understanding the structural transition from the northern Gulf Extensional Province to the San Andreas system. One of the principal Quaternary landscape features of the eastern Sierra El Mayor-Sierra Cucap√° is a prominent surface that slopes ~ 1-2¬į eastward towards the Colorado River Delta. Along the eastern side of the Sierra El Mayor and facing the Colorado River delta, but not along other piedmont mountain fronts that face the delta, this surface is terminated by a series of stepped terrace surfaces. The terrace surfaces are cut into fluvial-deltaic deposits from the Colorado River delta system and are capped by ~ 1 m thick gravels. Optically stimulated luminescence ages from interbedded coarse sands in the capping gravels of the upper surface and two of the inset terraces range from ~ 17 to 31 ka (average 24 ¬Ī 3 ka) but lack a systematic age trend from upper to lower surface. The underlying fluvial-deltaic deposits have older optically stimulated luminescence ages of 31 to 39 ka and suggest Colorado River delta deposition during the relatively stable interstadial of the Middle Wisconsinan substage (Marine Isotope Stage 3) when sea level was ca - 60 to - 80 m. Samples from depth-profiles in the capping gravels and from the top of the upper surface have a mean 10Be terrestrial cosmogenic nuclide age of 59 ¬Ī 5 ka. When corrected for inheritance, an average age of ~ 21 ka is computed for exposure of the capping gravels on the upper surface and inset terraces, which is in the range of the optically stimulated luminescence burial ages. Both the upper surface and inset terraces formed 17-30 ka at a transition time from dry to relatively wet climate when increased aggradation caused alluvial fan development on the upper surface. Regionally, these surfaces correlate with the Q2c-Q3a age deposits of the southwestern North America alluvial fan and terrace deposits. Sea level was also falling rapidly at this time, which may have caused the Colorado River to become entrenched near the range front thus allowing rapid response and down-cutting to form the inset terraces on the east side of the Sierra El Mayor facing the delta. Assuming the 34 ka delta deposits graded to a base level that was - 60 to - 80 m during Marine Isotope Stage 3, the computed surface uplift rate for the eastern side of the Sierra El Mayor is ~ 2.1-2.7 mm/yr. This uplift may be accommodated on a fault or fault system that is a southward extension of the Mexicali spreading and seismic zone that is buried beneath the Colorado River delta east of the Sierra El Mayor. The uplift rates from this study are consistent with geologic and geodetic data for the Sierra El Mayor and Sierra Cucap√°, and account for much of the missing extensional strain across the area.

    Objetivos. Nos propusimos determinar el grado de preparaci√≥n frente a los desastres naturales de los adultos mayores en los Estados Unidos y evaluar los factores que pueden afectar negativamente la salud y la seguridad durante este tipo de incidentes. M√©todos. Obtuvimos una muestra de adultos de 50 a√Īos en adelante (n‚ÄČ=‚ÄČ1‚ÄČ304) de la encuesta del 2010 del Estudio de la Salud y la Jubilaci√≥n (HRS por su sigla en ingl√©s). La encuesta recogi√≥ datos sobre las caracter√≠sticas demogr√°ficas generales, el estado de discapacidad o las limitaciones funcionales, y tambi√©n sobre factores y comportamientos relacionados con la preparaci√≥n frente a los desastres. Calculamos una puntuaci√≥n global de preparaci√≥n mediante indicadores individuales a fin de evaluar el grado de preparaci√≥n general. Resultados. La media de la edad de los participantes (n‚ÄČ=‚ÄČ1‚ÄČ304) fue de 70 a√Īos (desviaci√≥n est√°ndar [DE]‚ÄČ=‚ÄČ9,3). Solo 34,3% informaron que hab√≠an participado en un programa formativo o que hab√≠an le√≠do materiales sobre la preparaci√≥n para los desastres. Casi 15% indicaron que usaban dispositivos m√©dicos el√©ctricos que pod√≠an correr riesgo de no funcionar si se interrumpiera el suministro el√©ctrico. La puntuaci√≥n de preparaci√≥n indic√≥ que la edad m√°s avanzada, la discapacidad f√≠sica y el menor nivel de escolaridad y de ingresos se asociaban independiente y significativamente a un grado de preparaci√≥n general inferior. Conclusiones. A pesar de la mayor vulnerabilidad ante los desastres y del n√ļmero cada vez mayor de adultos mayores en los Estados Unidos, muchos de los problemas sustanciales que encontramos son remediables y requieren atenci√≥n en los sectores de la sociedad dedicados a la atenci√≥n cl√≠nica, a la salud p√ļblica y al manejo de situaciones de emergencia.

    Sobre la base de observaciones realizadas en Cerro Tololo y el Casleo, se presenta un cat√°logo con fotometr√≠a UBV integrada de 504 c√ļmulos y 120 asociaciones estelares en la Nube Mayor de Magallanes. Se determinan edades en t√©rminos de los tipos SWB y se identifican 38 c√ļmulos tipo VII, muchos de los cuales pueden ser c√ļmulos globulares cl√°sicos. El tama√Īo de las distribuciones espaciales crece uniformemente con la edad (tipo SWB), en tanto que existe una diferencia en el cociente axial entre los grupos m√°s j√≥venes y m√°s viejos que 30 millones de a√Īos, lo que implica una orientaci√≥n aproximadamente de frente para los primeros y una posici√≥n inclinada ~ 45o para el segundo grupo. Las asimetr√≠as en las distribuciones espaciales, juntamente con la falta de coincidencia de los centroides de los diferentes grupos de edad, sugiere que el disco de la Nube Mayor de Magallanes fue severamente perturbado en el pasado.

    A method is outlined by means of which it is possible to estimate high-resolution vertical displacements due to an earthquake even in the case where high-resolution topography is lacking before the earthquake. This result can be achieved by combining a highly accurate, post-event digital elevation model (DEM), for example lidar, with archived satellite imagery. The method is illustrated by calculating vertical displacements for the 2010 El Mayor-Cucapah earthquake. For this earthquake, there are both pre- and post-event lidar DEMs from which vertical displacements may also be estimated after correcting for the lateral advection of topography due to horizontal displacements. A comparison between the two means of deriving vertical displacements shows generally good agreement, with the displacements obtained using satellite imagery performing better in high relief areas. As a result of this property, we are able to trace the vertical offsets due to the El Mayor-Cucapah earthquake as the rupture jumped from the Pescadores fault to the Borrego fault in propagating through the high relief of the Sierra Cucapah.

    Fault dips are usually measured from outcrops in the field or inferred through geodetic or seismological modeling. Here we apply the classic structural geology approach of calculating dip from a fault's 3-D surface trace using recent, high-resolution topography. A test study applied to the 2010 El Mayor-Cucapah earthquake shows very good agreement between our results and those previously determined from field measurements. To obtain a reliable estimate, a fault segment ‚Č•120 m long with a topographic variation ‚Č•15 m is suggested. We then applied this method to the 2013 Balochistan earthquake, getting dips similar to previous estimates. Our dip estimates show a switch from north to south dipping at the southern end of the main trace, which appears to be a response to local extension within a stepover. We suggest that this previously unidentified geometrical complexity may act as the endpoint of earthquake ruptures for the southern end of the Hoshab fault.

    4 April 2010 M 7.2 El Mayor-Cucapah earthquake that occurred in Baja California, Mexico and terminated near the U.S. Mexican border caused slip on the Imperial, Superstition Hills, and East Elmore Ranch Faults. The pattern of slip was observed using radar interferometry from NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) instrument collected on 20-21 October 2009 and 12-13 April 2010. Right-lateral slip of 36 ¬Ī 9 and 14 ¬Ī 2 mm occurred on the Imperial and Superstition Hills Faults, respectively. Left-lateral slip of 9 ¬Ī 2 mm occurred on the East Elmore Ranch Fault. The widths of the zones of displacement increase northward suggesting successively more buried fault motion to the north. The observations show a decreasing pattern of slip northward on a series of faults in the Salton Trough stepping between the El Mayor-Cucapah rupture and San Andreas Fault. Most of the motion occurred at the time of the M 7.2 earthquake and the UAVSAR observations are consistent with field, creepmeter, GPS, and Envisat observations. An additional 28 ¬Ī 1 mm of slip at the southern end of the Imperial Fault over a <1 km wide zone was observed over a 1 day span a week after the earthquake suggesting that the fault continued to slip at depth following the mainshock. The total moment release on the three faults is 2.3 √ó 1023-1.2 √ó 1024 dyne cm equivalent to a moment magnitude release of 4.9-5.3, assuming shallow slip depths ranging from 1 to 5 km.

  19. Correlation of Peak Dynamic and Static Coulomb Failure Stress with Seismicity Rate Change after the M7.2 EL Mayor-Cucapah Earthquake

    2012-12-01

    We have investigated the relation between the April 4 Mw7.2 El Mayor-Cucapah earthquake and seismicity rate changes in southern California and northern Baja California in the months following the mainshock. Specifically, we use a dynamic rupture model with observational constraints for the event simulated in the SCEC 3D CVM4.0 (Roten and Olsen, 2009) to calculate the changes in the resulting static (dCFS) and dynamic Coulomb failure stress, parameterized by its largest positive amplitude (peak dCFS(t)). We employ a modified cross correlation between the seismicity rate change (for both undeclustered and declustered catalogs) and both dCFS and peak dCFS(t) in time and space (as used by Kilb et. al, 2002). We find that the correlation parameter is greater for peak dCFS(t) compared to dCFS and highest for periods after the mainshock of longer than 1 week for dCFS, and a maximum at 1 month for peak dCFS(t). We perform this analysis using both CVM-4 and CVM-H, investigating, in particular, which model better describes the increased seismicity NW of the rupture. The stress changes are rotated onto the focal mechanism of the June 15, 2010 Mw5.7 aftershock as well as onto optimum oriented planes (King, 1994). For regionally rotated stresses we find that while the dCFS values are very similar for the two CVMs, the corresponding peak dCFS(t) values are noticeably different. In particular, CVM-H generates a lobe of (directivity-induced) large peak dCFS(t) between the Elsinore and San Jacinto Faults toward the Los Angeles basin not present in the results from CVM-4. However, both CVMs produce similar peak dCFS(t) lobes near San Diego. Finally, we searched for threshold levels of dCFS and peak dCFS(t) that may be required to trigger earthquakes/aftershocks of different magnitude that might provide clues to earthquake prediction; we found a possible peak dCFS(t) threshold value of 0.7 bars for aftershocks (>4000) in regions of positive static stress. Peak dynamic stress change (in bars) calculated from CVM-4 for the April 4 Mw7.2 El Mayor- Cucapah earthquake, rotated onto a strike of 310 degrees, corresponding to the rupture of the Mw 5.72 June 15, 2010 event (epicenter depicted by the white star, mainshock by black star).

    The April 4, 2010 "Easter Sunday" earthquake on the US-Mexico border was the largest event to strike Southern California in the last 18 years. The earthquake occurred on a northwest trending fault close to, but not coincident with the identified 1892 Laguna Salada rupture. We investigate coseismic deformation due to the 2010 El Mayor-Cucapah earthquake using Synthetic Aperture Radar (SAR) imagery form ENVISAT and ALOS satellites, optical imagery from SPOT-5 satellite, and continuous and campaign GPS data. The earliest campaign postseismic GPS survey was conducted within days after the earthquake, and provided the near-field cosesmic offsets. Along-track SAR interferograms and amplitude cross-correlation of optical images reveal a relatively simple continuous fault trace with maximum offsets of the order of 3 meters. This is in contrast to the results of geological mapping that portrayed a complex broad zone of distributed faulting. Also, SAR data indicate that the rupture propagated bi-laterally from the epicenter near the town of Durango both to the North-West into the Cucapah mountains and to the South-East into the Mexically valley. The inferred South-East part of the rupture was subsequently field-checked and associated with several fresh scarps, although overall the earthquake fault does not have a conspicuous surface trace South-East of the hypocenter. It is worth noting that the 2010 earthquake propagated into stress shadows of prior events - the Laguna Salada earthquake that ruptured the North-West part of the fault in 1892, and several M6+ earthquakes that ruptured the South-East part of the fault over the last century. Analysis of the coseismic displacement field at the Earth's surface (in particular, the full 3-component displacement field retrieved from SAR and optical imagery) shows a pronounced asymmetry in horizontal displacements across both nodal planes. The maximum displacements are observed in the North-Eastern and South-Western quadrants. This pattern cannot be explained by oblique slip on a quasi-planar fault. Multi-parametric inversions of the space geodetic data suggest that the El Mayor-Cucapah earthquake occurred on a helix-shaped rupture, with Eastward dip in the Northern section and Westward dip in the Southern section. This interpretation is consistent with field observations of the surface rupture and aftershock data, and provides an explanation for a strong non-double-couple component suggested by the seismic moment tensor solution. The total geodetic moment of our best-fitting model is in a good agreement with the seismic moment. We will also discuss effects of the elastic structure on the inferred static rupture model, and observations of early postseismic deformation.

    Radar interferometry (InSAR), field measurements and creepmeters reveal surface slip on multiple faults in the Imperial Valley triggered by the main shock of the 4 April 2010 El Mayor-Cucapah Mw 7.2 earthquake. Co-seismic offsets occurred on the San Andreas, Superstition Hills, Imperial, Elmore Ranch, Wienert, Coyote Creek, Elsinore, Yuha, and several minor faults near the town of Ocotillo at the northern end of the mainshock rupture. We documented right-lateral slip (<40 mm) on northwest-striking faults and left-lateral slip (<40 mm) on southwest-striking faults. Slip occurred on 15-km- and 20-km-long segments of the San Andreas Fault in the Mecca Hills (‚ȧ50 mm) and Durmid Hill (‚ȧ10 mm) respectively, and on 25 km of the Superstition Hills Fault (‚ȧ37 mm). Field measurements of slip on the Superstition Hills Fault agree with InSAR and creepmeter measurements to within a few millimeters. Dislocation models of the InSAR data from the Superstition Hills Fault confirm that creep in this sequence, as in previous slip events, is confined to shallow depths (<3 km).

    In this manuscript, we introduce a framework for developing earthquake forecasts using Virtual Quake (VQ), the generalized successor to the perhaps better known Virtual California (VC) earthquake simulator. We discuss the basic merits and mechanics of the simulator, and we present several statistics of interest for earthquake forecasting. We also show that, though the system as a whole (in aggregate) behaves quite randomly, (simulated) earthquake sequences limited to specific fault sections exhibit measurable predictability in the form of increasing seismicity precursory to large m > 7 earthquakes. In order to quantify this, we develop an alert-based forecasting metric, and show that it exhibits significant information gain compared to random forecasts. We also discuss the long-standing question of activation versus quiescent type earthquake triggering. We show that VQ exhibits both behaviours separately for independent fault sections; some fault sections exhibit activation type triggering, while others are better characterized by quiescent type triggering. We discuss these aspects of VQ specifically with respect to faults in the Salton Basin and near the El Mayor-Cucapah region in southern California, USA and northern Baja California Norte, Mexico.

    Whether static or dynamic stress changes play the most important role in triggering earthquakes in the near field is still in debate. Here, we examine the seismicity rate changes in southern California following the 2010 Mw 7.2 El Mayor-Cucapah earthquake. We focus on the Salton Sea Geothermal Field (SSGF) and the San Jacinto Fault Zone (SJFZ) because of high-sensitivity continuous borehole recordings and ample background seismicity. A significant increase in seismic activity is found in both study regions immediately following the main shock. However, near the SSGF where the static Coulomb stress decreased, the seismicity rate dropped below the pre-main-shock rate after ňú1 month. In comparison, along the SJFZ with an increase in the static Coulomb stress, the seismicity rate remained higher than the background rate with several moderate-size earthquakes occurring in the subsequent months. While we cannot completely rule out other mechanisms, these observations are best consistent with a widespread increase in seismicity from dynamic stress changes immediately after the main shock, and longer term seismicity rate changes from static stress changes. Our observation, together with other recent studies, suggests that both static and dynamic stress changes are important in triggering near-field earthquakes, but their affected regions and timescales are different.

    The M7.2 El Mayor-Cucapah earthquake of April 4, 2010 in Mexico’s Baja California caused extensive damage to the agricultural area of Mexicali Valley. The damage included wide-spread liquefaction and lateral spreading which destroyed or damaged irrigation canals. Without water, wheat, alfalfa, and other crops were lost. Fields were cut by fissures and partially buried by massive sand blows. Regional tilting from the earthquake was a serious issue for the gravity-controlled irrigation system. Ruptured canals and groundwater from sand blows flooded fields, roads, and towns. Flooding further damaged crops and brought contamination with it. Fissures and scarps through farm communities cracked buildings; ruptured water, sewer, and other pipelines; and made roads temporarily difficult to pass. Economically, farmers, seasonal farm workers, and agricultural suppliers were affected; reducing their ability to consume the goods and services of businesses unrelated to agriculture. Similar damage was observed in earlier earthquakes over the past 100 years. Society quickly forgets how the earth responds to strong shaking. We hope to provide a vivid portrait of this agricultural disaster so that other farming communities prone to strong seismic shaking may visualize what can happen from their own inevitable future earthquake.

    Differential LiDAR provides unprecedented images of the near-field ground deformation and fault slip due to earthquakes. Here we examine the performance of the Iterative Closest Point (ICP) technique for data registration between pre- and post-earthquake LiDAR point clouds of varying density. We use the 2010 El Mayor-Cucapah data set as our region of interest since this earthquake produced different types of surface ruptures, yielding a variety of deformation styles for analysis. We also test a more simplistic, Chi-Squared minimization approach and find that it produces good results when compared to ICP. We present different techniques for visualizing large vector fields, and show how each method highlights a unique feature in the data set. Dense vector fields are useful when analyzing smaller deformations in the surface. A sparse, averaged vector field analyzes the bigger, overall shifts without interference caused by small details. Flow-based visualizations like Line Integral Convolution (LIC) graphs, provide insight into particular artifacts of data collection, such as distortions due to uncorrected pitch and yaw of the aircraft during the survey. Animations of the vector field establish the direction of movement in the landscape, quickly highlighting areas of interest.

    High-resolution surface topography is valuable for studying coseismic fault zone deformation and fault geometry. It enables us to measure three-dimensional surface displacements in earthquakes, as shown in recent studies that used light detection and ranging (lidar) to determine coseismic motion. However, the applicability of lidar is limited by its relatively high cost and low availability. In this study, we use the 2010 El Mayor-Cucapah earthquake to demonstrate the capability of Pleiades stereo imagery to measure coseismic vertical ground displacement. We acquired post-earthquake Pleiades tristereo imagery from backward, near-nadir, and forward orientations for a 45 km √ó 7 km portion of the epicentral area. One meter resolution digital elevation models (DEMs) were produced with the four different combinations of incidence angles and compared to the post-earthquake lidar DEM. Elevations from tristereo have slightly (ňú15%) smaller uncertainties than bistereo as the tristereo DEM incorporates more observations. Elevation differences between the Pleiades and post-earthquake lidar DEMs show that the vertical accuracy of the Pleiades DEMs is ňú0.3 m. By differencing the Pleiades DEM and the pre-earthquake, 5 m resolution lidar DEM, we mapped meter and submeter offsets along the faults obtaining results comparable to a previous study that differenced the two lidar DEMs. This is the first case study of assessing very high resolution (VHR) satellite stereo imagery to determine submeter vertical ground displacement in an earthquake. By extension, we expect it to be possible to measure submeter vertical offsets occurring in earthquakes using pre-earthquake and post-earthquake VHR stereo imagery.

    El Mayor-Cucapah earthquake occurred on 4 April 2010 in northeastern Baja California just south of the U.S.-Mexico border. The earthquake ruptured several previously mapped faults, as well as some unidentified ones, including the Pescadores, Borrego, Paso Inferior and Paso Superior faults in the Sierra Cucapah, and the Indiviso fault in the Mexicali Valley and Colorado River Delta. We conducted several Global Positioning System (GPS) campaign surveys of preexisting and newly established benchmarks within 30 km of the earthquake rupture. Most of the benchmarks were occupied within days after the earthquake, allowing us to capture the very early postseismic transient motions. The GPS data show postseismic displacements in the same direction as the coseismic displacements; time series indicate a gradual decay in postseismic velocities with characteristic time scales of 66 ¬Ī 9 days and 20 ¬Ī 3 days, assuming exponential and logarithmic decay, respectively. We also analyzed interferometric synthetic aperture radar (InSAR) data from the Envisat and ALOS satellites. The main deformation features seen in the line-of-sight displacement maps indicate subsidence concentrated in the southern and northern parts of the main rupture, in particular at the Indiviso fault, at the Laguna Salada basin, and at the Paso Superior fault. We show that the near-field GPS and InSAR observations over a time period of 5 months after the earthquake can be explained by a combination of afterslip, fault zone contraction, and a possible minor contribution of poroelastic rebound. Far-field data require an additional mechanism, most likely viscoelastic relaxation in the ductile substrate.

  8. Geologic and structural controls on rupture zone fabric: A field-based study of the 2010 Mw 7.2 El Mayor-Cucapah earthquake surface rupture

    We systematically mapped (scales >1:500) the surface rupture of the 4 April 2010 Mw 7.2 El Mayor-Cucapah earthquake through Sierra Cucapah to understand how faults with similar structural and lithologic characteristics control rupture zone fabric, which is here defined by the thickness, distribution and internal configuration of shearing in a rupture zone. Fault zone architecture and master fault dip showed the strongest controls on rupture zone fabric. Highly localized slip was observed along simple narrow fault cores (<20 m), whereas wide cores (>>50 m) composed of multiple zones of high shear strain had wider and more complex rupture zones that generally lacked principal-displacement scarps. Rupture zone thickness also increases systematically with decreasing fault zone dip. We observed that coseismic slip along faults that dip >40¬į was mostly confined to the fault core, whereas faults that dip as low as 20¬į had surface rupture entirely developed entirely outside of the fault zone. The lack of large off-fault strain along faults dipping >40¬į is contrary to predictions by dynamic stress modeling (e.g., Ma, 2009). We show that static tectonic loading, which varies significantly with fault orientation, has a significant effect not only on rupture zone fabric but also on the evolution of fault zone architecture in this transtensional setting. Rupture zones in undeformed alluvium are dominated by secondary fractures associated with fault-tip propagation, and arrays of fault scarps become wider and more complex with oblique slip compared to pure normal dip-slip or pure strike-slip. Field relations show that as magnitude of coseismic slip increases from 0 to 60 cm, the linkages between kinematically distinct fracture sets increases systematically to the point of forming a through going principal scarp, which is contrary to many analogue models (e.g., Tchalencko, 1970; Naylor et al., 1995) Our data indicate that secondary faults and penetrative off-fault strain continue to accommodate the oblique kinematics of coseismic slip after the formation of a through going principal scarp.

    Very high-resolution (VHR) imagery can in principle measure surface topography with decimetric precision. The question is how well 3D mapping based on VHR stereo imagery is capable of capturing sub-metric height changes occurring in an earthquake, particularly those in remote areas? The aim of this study is to assess the capability of the Pleiades satellites to determine such height changes. We acquired Pleiades stereo imagery with backward (B), near-nadir (N) and forward (F) orientations over a 40 km √ó 5 km area in Baja California, Mexico, part of the epicentral area of the 2010 Mw 7.2 El Mayor-Cucapah earthquake. Coverage was chosen to coincide with the post-seismic LiDAR digital elevation model (DEM) for the area. DEMs have been produced with four different combinations of incidence angles (B-N, N-F, B-F and B-N-F). The raw point cloud has the lowest average density of ~0.7 points/m2 for B-F, ~1.0 points/m2 for B-N and N-F, and the greatest average density of ~3 points/m2 for tri-stereo (B-N-F). Compared to the post-earthquake LiDAR DEM, the Pleiades DEMs have a mean error of 1 m to 4 m, with a standard deviation of 0.5 m to 0.7 m. A series of topographic profiles from the Pleiades DEMs across the earthquake rupture were used to measure vertical offsets. These profiles show that the Pleiades DEM is capable of capturing vertical offsets of ~0.5 m. The measurements of vertical offsets from tri-stereo have smaller uncertainties than bi-stereo; this suggests that the tri-stereo DEM incorporating redundant observations is more robust and reliable. By differencing the 1-m tri-stereo Pleiades DEM and the pre-earthquake, lower-resolution (5-m) LiDAR DEM, we mapped metre and sub-metre offsets along the faults obtaining results comparable to a previous study that differenced the two LiDAR DEMs (Fig. 1). By extension, we expect it to be possible in similar settings to measure sub-metre vertical offsets occurring in earthquakes using pre- and post-event Pleiades stereo imagery.

  10. Coupling of Pore Pressure and Ground Motion Data Recorded During the 2010 El Mayor-Cucapah (Baja California) Earthquake at the NEES@UCSB Wildlife Station

    Pore pressure built up during an earthquake and the hazard associated with soil liquefaction present a major challenge for our society, as was dramatically displayed during the 2011 Higashi Nihon Daishinsai (Tohoku-oki, Japan) earthquake. Currently, there is a consensus among scientists that a better assessment of the risk associated with liquefaction requires a better understanding of the coupling between pore pressure time histories and ground motion time histories. Specifically, there is a basic need to investigate the coupling as a function of the frequency content of the ground motion. The 2010 El Mayor-Cucapah (Baja California) earthquake (M 7.2) provides a remarkable opportunity to undertake such an investigation and lay the basis to model the coupling. The event was well recorded at the NEES@UCSB Wildlife station located 110 km from the hypocenter. The station is equipped with three-component strong-motion accelerometers at the surface and in boreholes at various depths and with pore pressure transducers located in a saturated, liquefiable layer. The recorded pore pressure and ground motion time histories are both characterized by a frequency content that is a function of time. A wavelet representation is a natural approach to investigate non-stationary time histories. To study the coupling between two signals we use the following procedure: We first compute the wavelet coefficients associated with the two signals. Then we compute the correlation between the wavelet coefficients of the two signals as a function of the frequency. Correlation coefficients provide information about the degree of linear dependence between the two signals. To account for the presence of multiplicative constants relating the wavelet coefficients of the first signal to the wavelet coefficients of the second signal, we compare the square norm of the wavelet coefficients of the two signals for the available frequency range. Additionally, investigating the distribution of the square norm of the wavelet coefficients as a function of the frequencies allows the identification of the dominant wavelet coefficients necessary to reconstruct the signal. We discuss the procedure outlined above for the following cases: when the two signals correspond to two ground motion time histories located at different depths; when the two signals correspond to two pore pressure time histories located at different depths; and when one of the two signals corresponds to a ground motion time history and the second corresponds to pore pressure both (approximately) recorded at the same depth.

  11. Analysis of Triggering of Earthquakes and Tremor in the Western U.S. due to the 2010 El Mayor Cucapah Earthquake and the Mw6.8 Mendocino Triple Junction Earthquake in 2014

    Recent studies indicate that the passage of seismic waves from large earthquakes are able to trigger small earthquakes and tremor at regional distances. These small events may be detected by applying a high-pass filter to seismograms to remove the much larger ground motion amplitudes from the large distant earthquake. Our interests are in examining the local triggering of earthquakes and tremor throughout the West Coast of North America from the magnitude 7.2 El Mayor-Cucapah 2010 earthquake and the magnitude 6.8 Northern California, March 10, 2014 earthquake, just north of the Mendocino Triple Junction. We will present the results of the analysis of waveform data from hundreds of seismometers throughout Southern California, Northern California, Oregon, Washington, as well as some stations bordering these states. Our preliminary results suggest that triggering of local earthquakes and tremor occurred for both earthquakes. In the case of the records of the Southern California stations for the El Mayor Cucapah 2010 earthquake, 27 stations showed triggering near the seismic station. 13 of these stations are located in or near known geothermal areas, while others were located along active faults and one offshore. While conducting this study, we detected an instrumental noise signal present in 63 of the Southern California seismograms for the El Mayor-Cucapah earthquake. Initially, the signal looked like a typical triggered event, yet with further investigation we found its likely cause to be instrumental noise. We plan to relate our observations of triggered seismicity and tremor to the tectonic environment to test the hypothesis that triggering and tremor most commonly occurs in volcanic and geothermal areas.

    The 4 April 2010 Mw 7.2 El Mayor-Cucapah (EMC) earthquake provides the best opportunity to date to study the lithospheric response to a large (>M6) magnitude earthquake in the Salton Trough region through analysis of Global Positioning System (GPS) data. In conjunction with the EarthScope Plate Boundary Observatory (PBO), we installed six new continuous GPS stations in the months following the EMC earthquake to increase station coverage in the epicentral region of northern Baja California, Mexico. We modeled the pre-EMC deformation field using available campaign and continuous GPS data for southern California and northern Baja California and inferred a pre-EMC secular rate at each new station location. Through direct comparison of the pre- and post-EMC secular rates, we calculate long-term changes associated with viscoelastic relaxation in the Salton Trough region. We fit these velocity changes using numerical models employing an elastic upper crustal layer underlain by a viscoelastic lower crustal layer and a mantle half-space. Forward models that produce the smallest weighted sum of squared residuals have an upper mantle viscosity in the range 4-6 √ó 1018 Pa s and a less well-resolved lower crustal viscosity in the range 2 √ó 1019 to 1 √ó 1022 Pa s. A high-viscosity lower crust, despite high heat flow in the Salton Trough region, is inconsistent with felsic composition and might suggest accretion of mafic lower crust associated with crustal spreading obscured by thick sedimentary cover.

  18. Testing long-period ground-motion simulations of scenario earthquakes using the Mw 7.2 El Mayor-Cucapah mainshock: Evaluation of finite-fault rupture characterization and 3D seismic velocity models

    Graves, Robert W.; Aagaard, Brad T.

    2011-01-01

    Using a suite of five hypothetical finite-fault rupture models, we test the ability of long-period (T>2.0 s) ground-motion simulations of scenario earthquakes to produce waveforms throughout southern California consistent with those recorded during the 4 April 2010 Mw 7.2 El Mayor-Cucapah earthquake. The hypothetical ruptures are generated using the methodology proposed by Graves and Pitarka (2010) and require, as inputs, only a general description of the fault location and geometry, event magnitude, and hypocenter, as would be done for a scenario event. For each rupture model, two Southern California Earthquake Center three-dimensional community seismic velocity models (CVM-4m and CVM-H62) are used, resulting in a total of 10 ground-motion simulations, which we compare with recorded ground motions. While the details of the motions vary across the simulations, the median levels match the observed peak ground velocities reasonably well, with the standard deviation of the residuals generally within 50% of the median. Simulations with the CVM-4m model yield somewhat lower variance than those with the CVM-H62 model. Both models tend to overpredict motions in the San Diego region and underpredict motions in the Mojave desert. Within the greater Los Angeles basin, the CVM-4m model generally matches the level of observed motions, whereas the CVM-H62 model tends to overpredict the motions, particularly in the southern portion of the basin. The variance in the peak velocity residuals is lowest for a rupture that has significant shallow slip (<5 km depth), whereas the variance in the residuals is greatest for ruptures with large asperities below 10 km depth. Overall, these results are encouraging and provide confidence in the predictive capabilities of the simulation methodology, while also suggesting some regions in which the seismic velocity models may need improvement.

    Aerial LiDAR surveys reconstruct with amazing fidelity the sinuosity of terrain relief. In this research we explore the 3D deformation field at the surface after a big earthquake (M7.2) by comparing pre- to post-event aerial LiDAR point clouds. The April 4 2010 earthquake produced a NW-SE surface rupture ~110km long with right-lateral normal slip up to 3m in magnitude over a very favorable target: scarcely vegetated and unaltered desert mountain range, sierras El Mayor and Cucapah, in northern Baja California, close to the US-México border. It is a plate boundary region between the Pacific and North American plates. The pre-event LiDAR with lower point density (0.013-0.033 pts m-2) required filtering and post-processing before comparing with the denser (9-18 pts m-2) more accurate post event dataset. The 3D surface displacement field was determined using an adaptation of the Iterative Closest Point (ICP) algorithm, implemented in the open source Point Cloud Library (PCL). The LiDAR datasets are first split into a grid of windows, and for each one, ICP iteratively converges on the rigid body transformation (comprising translations and rotations) that best aligns the pre- to post-event points. Perturbing the pre- and post-event point clouds independently with a synthetic right lateral inverse displacements of known magnitude along a proposed fault, ICP recovered the synthetically introduced translations. Windows with dimensions of 100-200m gave the best results for datasets with these densities. The simplified surface rupture photo interpreted and mapped in the field, delineates very well the vertical displacements patterns unveiled by ICP. The method revealed block rotations, some with clockwise and others counter clockwise direction along the simplified surface rupture. As ground truth, displacements from ICP have similar values as those measured in the field along the main rupture by Fletcher and collaborators. The vertical component was better estimated than the horizontal having the latter problems in flat areas as expected. Hybrid approaches, as simple differencing, could be taken in these areas. Outliers were removed from results. ICP detected extraction from quarries developed between the two dates of LiDAR collection and expressed as a negative vertical displacement close to the sites. To improve the accuracy of the 3D displacement field, we intend to reprocess the pre-event source survey data to reduce the systematic error introduced by the sensor. Multidisciplinary approach will be needed to make tectonic inferences from the 3D displacement field revealed by ICP, about the processes at depth expressed at surface.

  20. A New Ensemble-Based Method for Assessing Uncertainties and Parameter Tradeoffs in Complex Models of Postseismic Deformation: Application to the 2010 M=7.2 El Mayor-Cucapah Earthquake

    The 2010 M=7.2 El Mayor-Cucapah earthquake occurred in the Salton Trough, a region of thinned lithosphere and high heat flow, and the postseismic deformation following this earthquake presents a unique opportunity to study the rheology of extensional environments and the mechanics of ductile flow within and beneath the lithosphere. Previous work [Rollins et al, in prep.] revealed that GPS timeseries of surface displacement following the earthquake were well fit to a coupled model simulating stress-driven afterslip on the deep extension of the coseismic rupture, Newtonian viscoelastic relaxation in a low-viscosity zone in the lower crust of the Salton Trough aligned with areas of high heat flow, and Newtonian viscoelastic relaxation in a three-dimensional asthenosphere with geometry matching that of the regional lithosphere-asthenosphere boundary inferred from receiver functions. Extending the success of this model to a robust interpretation of the mechanics of deformation at depth requires a better understanding of uncertainties and trade-offs between parameters (depth of the brittle-ductile transition, viscosities of the lower crust and asthenosphere, geometry of viscosity anomalies in the Salton Trough, frictional parameters of the possible downdip extensions of the coseismic rupture, and correlations among these parameters). We will show results from recent work that uses a newly developed method to efficiently explore this model space in a Bayesian sense. The method employs the Neighborhood Algorithm of Sambridge [1999], which makes use of Voronoi cells to optimize the search in the model space, samples regions that contains models of acceptable data fit, and extracts robust information from the ensemble of models obtained. The method is particularly well suited to identify a class of models that fit geodetic data approximately equally well, allowing us to present and discuss a range of possible deformation mechanisms. This method can be applied to any study of postseismic deformation and represents a significant step towards directly inferring best-fit rheological parameters from geodetic data in a way that considers many deformation mechanisms simultaneously.

    Following the 4 April 2010 M7.2 El Mayor-Cucapah earthquake, teams from UC Riverside, UC Santa Barbara, and San Diego State University installed an array of 8 temporary seismometers in the Yuha Desert area north of the Mexican border. This temporary array complemented the existing network stations and continuously recorded data from the aftershock sequence from 6 April through 14 June 2010. SCSN and the temporary aftershock array data will be used to study several aspects of fault structure and behavior, including precise relocation of the aftershock sequence. While the mainshock sequence ruptured multiple fault strands west of the Cerro Prieto fault, and south of the Sierra Cucapah Range, the aftershocks are densely clustered in three areas. The largest cluster is located to the northwest of the mainshock, in an area with no previously mapped faults. By relocating aftershocks, we hope to illuminate the network of faults that extend from the Laguna Salada fault in Mexico to its northern extension towards the Elsinore and San Jacinto faults. Right-lateral displacements up to 2 cm were identified on several right- and left-lateral fault segments by the USGS/CGS geologists in the area south of Hwy 98, and into the Pinto Wash (Treiman et al., personal communication, 2010). We relocate aftershocks within a 20 km by 14 km region containing 1 network and 8 temporary stations. Within this region over 4,000 aftershocks are in the SCEDC catalog from 6 April to 14 June 2010, during the time the temporary network was installed. The P and S wave arrival times for both the network and temporary stations were manually picked for each of these events. We compute the double difference hypocenter locations using the picked phase arrivals and waveform cross-correlations in the hypocenter relocation program, hypoDD (Waldhauser & Ellsworth 2000). In the event relocation, we used the velocity profile for the Imperial Valley from the SCEC Unified Velocity Model (Version 4). Future work will include detecting and relocating events that are not in the SCEDC catalog using the continuous data from the temporary array. All of the data will then be relocated using waveform cross-correlation in hypoDD to further improve the locations. Since little is known about the fault structure in the Yuha Desert region, we hope that accurate earthquake locations will help illuminate the complex and unmapped fault structure in the area. Additionally, more precise earthquake depths will help determine the extent of the seismogenic zone.

    We study postseismic deformation after the Mw 7.7 earthquake in the Balochistan region of western Pakistan on 24 September 2013 and the Mw 7.2 El Mayor-Cucapah (EMC) earthquake in Baja California of northern Mexico on 4 April 2010. Pakistan InSAR measurements from the German TerraSAR-X (TSX) and Canadian RADARSAT-2 (RS2) satellites include TSX narrow stripmap beams on a descending track, RS2 wide strip modes, and TSX wide-swath ScanSAR images on an ascending track, specially acquired with interferometric alignment of ScanSAR bursts. For the EMC earthquake, InSAR includes Envisat, ALOS, and RS2 satellites and NASA/JPL UAVSAR airborne InSAR, with piece-wise time coverage. Plate Boundary Observatory acquires continuous GPS data and others collect campaign GPS. Interferograms show significant afterslip on both main ruptures in the first weeks and months, not masked by the atmospheric effects. Balochistan shallow afterslip reaches at least 10 cm in 2-4 months in the same area as the largest coseismic slip, but less near the aftershock activity. Rapid afterslip was observed primarily at the ends of the EMC mainshock rupture where the strike changes, with magnitudes up to 30 cm. Large variations of tropospheric water vapor complicate measurement of small long-wavelength deformation so we do time series analysis. We expect viscoelastic relaxation after these two strike-slip earthquakes to differ due to completely opposite tectonic settings: EMC earthquake in the Salton Trough rift and fast-moving strike-slip system, where crust and lithosphere are thin and hot with very shallow asthenosphere, and Balochistan earthquake in the shortening Makran accretional prism with much slower strike-slip deformation rates and cold and thick lithosphere of the subducting Arabian plate directly beneath it, so asthenosphere is much deeper. Studies have found rapid and large viscoelastic relaxation for the EMC quake, but we don't expect measurable relaxation in the Balochistan area in the first year, based on preliminary modeling. These very different lithospheric configurations have strong implications for transfer of stress and future earthquake risk.

  3. Late Quaternary Range-Front Fault Scarps in the Western Sierra El Mayor, Baja California, Mexico: A Geomorphologic Expression of Slip Across an Active Low-Angle Normal Fault

    The western margin of the Sierra El Mayor (SEM), in northeastern Baja California, is controlled by an active, top-to-the-west, low-angle normal fault named the Canada David detachment (CDD) that accommodates part of the extensional component of shearing between the Pacific and North American plates. The CDD has a length of 60 km and shows a curvilinear trace with two major antiformal and synformal megamullion pairs. Late Quaternary slip has produced a broad array of Quaternary scarps cutting alluvial fans along nearly the entire length of the CDD. Detailed mapping reveals eight regional strath terraces distinguished by surface weathering characteristics, soil profile development and relative elevation. Relative height between terraces increases in domains where the CDD and basin deposits are being uplifted due to either the basinward migration of faulting (e.g., rolling hinge) or flexural uplift in antiformal megamullion domains. Linear diffusion analysis of 46 synthetic fault scarps, with a calculated angle of repose őėo = 28.75¬į, reveal fault scarp domains exhibiting both multi-modal and unimodal distribution of diffusion ages (kt). Uni-modal domains are typically younger, but there is no systematic variation in scarp age with distance along the CDD. Scarps yielding negative kt ages (i.e. scarps steeper than őėo) are common in the north, near inferred locations of important historic seismic events. Microseismicity drops off significantly adjacent to these very young scarp arrays, which likely reflects a recent post-seismic stress drop. Domains of high seismic risk are identified by high microseismicity and lack of young scarps. Minimum estimates of the diffusivity constant (k) are calculated by coupling scarp diffusion ages and 10Be surface exposure ages of the faulted deposits. In the southernmost SEM a Q6 terrace with a minimum surface exposure age t = 233¬Ī6.6 ky (weighted mean of six rock samples) is cut by scarps with an average kt = 11.25¬Ī9.31 m2, which yields a minimum k = 0.05¬Ī0.04 m2/ky. Scarps cutting Q4 terraces yield diffusion ages (kt = 0.16¬Ī0.04 m2) consistent with the inferred post-glacial age of the four youngest terraces.

  4. Spectral Amplification Factors of Long-Period (3 to 10 s) Strong Ground Motions in and around the Los Angeles Basin during the Mw7.2 El Mayor-Cucapah Earthquake of April 4, 2010

    Hatayama, K.; Kalkan, E.

    2012-12-01

    We evaluated spectral amplification factors of long-period ground motions (3 to 10 s) in the Los Angeles (LA) basin by computing Fourier spectral ratios of the basin sites with respect to the surrounding reference hard-rock sites from the Mw7.2 April 4, 2010 El Mayor-Cucapah earthquake records and presented period-specific (4, 6, 8 and 10 s) maps of amplification factors for the long periods. This earthquake was the first event providing many (236) high-quality recordings to study spatial variation of long-period amplification in the LA basin. We also tried numerical wave propagation simulations for two of the recent 3D seismic-velocity models for south California: SCEC (Southern California Earthquake Center) CVM (Community Velocity Model)-4.0 and CVM-H 6.2 to examine how these models account for the observed long-period amplification factors. Comparison of the period-specific maps of amplification factors between the observation and the simulation for the two velocity models shows that both CVM-4.0 and CVM-H 6.2 can roughly reproduce the observed amplification factors with the period range of 8 to 10 s in the LA basin. Concerning the shorter-period range (4 to 6 s), however, both of the two models leave more to be improved so that the observed amplification factors can be better simulated. We also find that CVM-4.0 has an advantage over CVM-H 6.2 in terms of the south-eastern part of the LA basin, because CVM-H 6.2 indicates non-observed large amplification there, while CVM-4.0 does not indicate the false amplification. For the period of 10 s, the largest amplification factor of about 5 was observed in the central part of the LA basin, which is well simulated in terms of good agreements between the observed and the simulated amplification factors. The simulation from the two velocity models also indicates the large amplification even in the San Gabriel (SG) valley, which disagrees with the observation. For 8 s, larger amplification factors of about 5 were observed not only in the central part of the LA basin but also in the SG valley, which are also well simulated by both of the two models. The CVM-H 6.2 simulation undershoots the observation in the western part of the LA basin, while CVM-4.0 can almost reproduce it. For 6 s, the largest amplification is observed in the western part of the basin (Manhattan Beach), although the amplification in the central part is also large. Around Manhattan Beach, the ground motions with this period are amplified by a factor of 10. There is significant discrepancy between the observation and the simulation for the two models in terms of the places where the largest amplification occurs. For the period of 4 s, the largest amplification factor of about 8 occurs in the central part of the LA basin. Again, the spatial pattern of amplification is basically failed to simulate by either of the two models.

  5. Characteristics of Long-Period (3 to 10 s) Strong Ground Motions Observed in and around the Los Angeles Basin during the Mw7.2 El Mayor-Cucapah Earthquake of April 4, 2010

    We examined the characteristics of long-period strong ground motions within a period range of 3 to 10 s in and around the Los Angeles (LA) basin during the Mw7.2 El Mayor-Cucapah earthquake. The contour map of the observed peak ground velocity (PGV) values clearly shows that the LA basin significantly amplifies the long-period motions. The largest PGV values observed within the LA basin range from 0.1 to 0.12 m/s, though the basin is around 350 km away from the epicenter. These largest PGV values were recorded at seven stations in the central part, and one station in the western part of the basin. The Fourier acceleration spectra of records from these eight stations are predominant at the periods of 6 to 8 s with the corresponding peak values of 1 to 1.4 m/s. The ratio of Fourier amplitudes with respect to a reference site (STG station of the Southern California Seismic Network, located on hard rock in the southeast edge of the LA basin) show that the spectral amplitudes at these eight stations are 5 to 13 times larger than those at the reference site within a wide period range, 5.5 to 9 s. To understand how the spatial variation of amplification for the long-period motions is related to the basin underground structure, we plotted contours of the amplification factors at 3, 5, 7 and 10 s spectral periods with respect to the reference site (i.e. STG station) onto several different maps, where depths to different S-wave velocities (Vs) are also depicted using the latest SCEC Community Velocity Model (CVM-H 6.2). Comparison of amplification contours with the basin model indicates that for the 10 s spectral period, the largest amplification occurs in the central part of the LA basin where the depth to the Vs of 3.2 km/s reaches to the maximum, 9.5 km. For the 3, 5 and 7 s spectral periods, the amplification becomes larger in almost the same area as the 10 s case (the central part of the LA basin) and also in the San Gabriel valley, where the depth to the Vs of 1.5 km/s reaches to the maximum, 3.7 km. Although the depth to bedrock (Vs > 3.2 km/s) is shallower (3.6 to 4 km) in the San Gabriel valley than the LA basin, the large amplification is due to the thick soft sediments (Vs < 1.5 km/s). This suggests importance of precise seismic velocity profiles at both shallow- and deep-part of sedimentary basins for a more accurate prediction of long-period strong ground motions.

    In this work we present preliminary results obtained from the analysis carried out on the medium-size bubble structures located in the southeast region of the Large Magellanic Cloud (LMC). We determine the characteristic parameters of these structures (surface brightness; electronic density; emission measure; mass; luminosity; ambient density; age; energy; among others). This will allow us to discriminate which is the origin (stellar wind; supernova explosion; or other mechanisms) of the different bubbles that form the LMC9 supershell. Thus; we will try to determine whether the analyzed objects have kinematically some identity as a group; or they are relatively isolated objects on the diffuse background they belong to.

    Based on Washington photometric observations carried out with the Victor Blanco 4m telescope at Cerro Tololo Inter-American Observatory (Chile); we examine the Large Magellanic Cloud (LMC) recent chemical evolution. As tracers of the LMC metallic enrichment; we observed and used 81 star clusters projected on different regions of the galaxy. Our sample includes 44 previously unstudied clusters. We find that the more metal-rich clusters are mainly located in the inner disc; while more metal-poor clusters are distributed throughout the entire disc. Intermediate-age clusters tend to be located at greater deprojected Galactocentric distances while the youngest ones are mainly found in the inner disc. These trends are maintained when the sample is complemented with others found in the literature and studied with the same technique. The resulting age-metallicity relationship appears to be independent of which LMC region is considered. FULL TEXT IN SPANISH

    Many studies have tried to identify genetic markers for infectious diseases, some of them have focused on human leukocyte antigens (HLA). The products of HLA genes interact with surface-specific receptors of T lymphocytes, resulting in activation of the host's immune response. Association of bacterial, viral, parasitic and fungal infections with the host's HLA has been widely investigated. The type and strength of this association differs among distinct populations, as well as among racial and/or ethnic groups. The new molecular methods for the identification of the HLA alleles, and the resulting new nomenclature, have contributed to a better understanding of this system. Unfortunately, this information has not been adequately transmitted to clinicians, which hampers the understanding of the association between the HLA system and diseases. We revised relevant studies on the association of HLA genes with infectious diseases, demonstrating their importance in the pathogenic mechanisms, through increased susceptibility or protection against infections and their complications.

We confirm a high probability of physical reality for some of the studied binary or multiple system candidates. We also determine their probable formation epochs and show that some of them could not be genuine physical systems. In all cases we recommend to confirm the physical association of these SC systems by examining their heliocentric distances and relative radial velocities. FULL TEXT IN SPANISH

    We present results obtained for 41 faint star clusters located in the bar and the disc of the Large Magellanic Cloud (LMC). The observations were carried out with the ``Victor Blanco'' 4m telescope at Cerro Tololo Inter-American Observatory using the Washington and Kron-Cousins filters. Clusters' linear radii were determined from the stellar density radial profiles. Using theoretical isochrones; we derived ages and metallicities from extracted color-magnitude diagrams; previously cleaned from field star contamination. Whenever possible; we also derived ages using the parameter and estimated metallicities from the Standard Giant Branch procedure. We find that the two methods for both age and metallicitiy determination are in good agreement with each other. Since none of the observed clusters has been previously studied; the present fundamental parameter determinations turn out to be the first ones. Seventeen clusters were found to be intermediate-age clusters (1-2 Gyr); with [Fe/H] values ranging from -0.4 to -0.8. The remaining 24 clusters are aged between 125 and 900 Myr and their metallicities range between 0.0 and -0.4. FULL TEXT IN SPANISH

CMD cluster features turn out to be identifiable when performing annular extrac- tions around their respective centres, once they were cleaned from field star contamination; their main sequences extending from one up to four mag- nitudes downwards. The clusters resulted to be small angular size objects projected or immersed in dense star fields, as judged from their radial stellar density profiles, so that crowding effect could be responsible for the limited magnitude reached in some cases. We estimated their ages from isochrone fitting - along with the E(B - V ) colour excesses - assuming a metallicity of Z = 0.008 ([Fe/H] = -0.4 dex) and a LMC distance modulus of (m - M)o = 18.50 ¬Ī 0.10 mag.

    Simulation systems are becoming increasingly essential in medical education. Hereby, capturing the physical behaviour of the real world requires a sophisticated modelling of instruments within the virtual environment. Most models currently used are not capable of user interactive simulations due to the computation of the complex underlying analytical equations. Alternatives are often based on simplifying mass-spring systems, being able to deliver high update rates that come at the cost of less realistic motion. In addition, most techniques are limited to narrow and tubular vessel structures or restrict shape alterations to two degrees of freedom, not allowing instrument deformations like torsion. In contrast, our approach combines high update rates with highly realistic motion and can in addition be used with respect to arbitrary structures like vessels or cavities (e.g. atrium, ventricle) without limiting the degrees of freedom. Based on energy minimization, bending energies and vessel structures are considered as linear elastic elements; energies are evaluated at regularly spaced points on the instrument, while the distance of the points is fixed, i.e. we simulate an articulated structure of joints with fixed connections between them. Arbitrary tissue structures are modeled through adaptive distance fields and are connected by nodes via an undirected graph system. The instrument points are linked to nodes by a system of rules. Energy minimization uses a Quasi Newton method without preconditioning and, hereby, gradients are estimated using a combination of analytical and numerical terms. Results show a high quality in motion simulation when compared to a phantom model. The approach is also robust and fast. Simulating an instrument with 100 joints runs at 100 Hz on a 3 GHz PC.

  6. Effects of the El Mayor Cucapah April 4, 2010 earthquake and water management decisions on the Colorado River Delta tidal inundation patterns: implications for shorebirds habitat availability

    2010-12-01

    The Upper Gulf of California and Colorado River Delta (CRD) provide feeding and resting areas for migratory and resident shorebirds. Coastal and inland wetlands create a variety of habitats that support 31 shorebird species. Total shorebirds during the winter and spring migration ranges from 56,156 to 195,073. The Cienega de Santa Clara is an artificial wetland that receives saline water inflows from the United States, and the southeastern portion (the Santa Clara Slough) receives a mix of brackish effluent from the Cienega and occasional tidal inundation during extreme high tides. This transitional wetland between the sea and the land is one of the main shorebird aggregation areas within the CRD, supporting 29 to 75% of the individuals using the entire Upper Gulf and CRD. The Cienega de Santa Clara is currently experiencing a 30% reduction in inflows due to operation of the Yuma Desalting Plant in the United States. The 2010 Baja California earthquake caused changes in the tidal water inflows patterns in the delta. Time sequence Landsat images and aerial observations showed that a new wetland area has been created since tidal water inflows are now diverted from the southeast edge of the Cienega to the southwest areas due to subsidence effects. The aim of this study was to document the changes in the shorebird inland habitats to predict shifts in shorebird habitat use by using aerial and ground surveys before and after the earthquake. Preliminary results shows that some of the areas with a high density of shorebird use has dried out mainly as a consequence of the reduction in water inflows to the Cienega from the United States and diversion of water from the Santa Clara Slough to the new tidal basins northwest of the Slough. Aerial surveys suggest that shorebirds were not yet visiting the new wetland area during the past spring migration and were more abundant over the San Felipe coastline and Montague Island. Shorebird habitat has been influenced by a combination of water management decisions, tidal dynamics, and landform changes due to the recent seismic event in the CRD. Further monitoring is needed to determine if shorebirds will relocate to new habitat or diminish in numbers in this important ecosystem.

    Sediments of the Sima de los Huesos vary greatly over distances of a few meters. This is typical of interior cave facies, and caused by cycles of cut and fill. Mud breccias containing human bones, grading upwards to mud containing bear bones, fill an irregular surface cut into basal marks and sands. The lack of Bedding and the chaotic abundance of fragile speleothem clasts in the fossiliferous muds suggests that the deposit was originally a subterranean pond facies, and that after emplacement of the human remains, underwent vigorous post-depositional rotation and collapse and brecciation, caused by underlying bedrock dissolution and undermining. The fossiliferous deposits are capped by flowstone and guano-bearing muds which lack large-mammal fossils. U-series and radiocarbon dating indicates the capping flowstones formed from about 68 ka to about 25 ka. U-series analyses of speleothem clasts among the human fossils indicate that all are at, or close to, isotopic equilibrium (> 350 ka). The distribution of U-series dates for 25 bear bones (154 +/- 66 ka) and for 16 human bones (148 +/- 34 ka) is similar and rather broad. Because the human bones seem to be stratigraphically older than chose of the bears, the results would indicate that most of the bones have been accumulating uranium irregularly with time. Electron spin resonance (ESR) analyses of six selected bear bones indicates dates of 189 +/- 28 ka, for which each is cordant with their corresponding U-series date (181 +/- 41 ka). Combined ESR and U-series dates for these samples yielded 200 +/- 4 ka. Such agreement is highly suggestive that uranium uptake in these bones was close to the early-uptake (EU) model, and the dates are essentially correct. Another three selected samples yielded combined ESR U-series dates of 320 +/- 4 ka with a modeled intermediate-mode of uranium uptake. The dating results, therefore, seem to provide a firm minimum age of about 200 ka for the human entry: and suggestive evidence of entry before 320 ka. PMID:9300339

    The fit of synthetic spectra has proved to be a powerful tool for determining astrophysical parameters of stellar clusters (SCs). Such methodology is particularly useful to treat integrated spectra of extragalactic SCs. In this work, we present the results obtained by applying this technique to a sample of SCs belonging to the Large Magellanic Cloud (LMC) observed from CASLEO, and using the starlight code. The fitting of the data was performed by means of evolutive--synthesis models of simple--stellar populations of different ages and metallicities, based on the MILESM stellar libraries. The integrated spectra of 34 SCs of the LMC were fitted in order to obtain the age and metallicity of each object. This study also presents a comparison between the properties derived from those fittings and the method of confrontation of our observations with spectral templates of well known ages.

  12. Understanding differences in access and use of healthcare between international immigrants to Chile and the Chilean-born: a repeated cross-sectional population-based study in Chile

    PubMed Central

    2012-01-01

    Introduction International evidence indicates consistently lower rates of access and use of healthcare by international immigrants. Factors associated with this phenomenon vary significantly depending on the context. Some research into the health of immigrants has been conducted in Latin America, mostly from a qualitative perspective. This population-based study is the first quantitative study to explore healthcare provision entitlement and use of healthcare services by immigrants in Chile and compare them to the Chilean-born. Methods Data come from the nationally representative CASEN (Socioeconomic characterization of the population in Chile) surveys, conducted in 2006 and 2009. Self-reported immigrants were compared to the Chilean-born, by demographic characteristics (age, sex, urban/rural, household composition, ethnicity), socioeconomic status (SES: education, household income, contractual status), healthcare provision entitlement (public, private, other, none), and use of primary services. Weighted descriptive, stratified and adjusted regression models were used to analyse factors associated with access to and use of healthcare. Results There was an increase in self-reported immigrant status and in household income inequality among immigrants between 2006 and 2009. Over time there was a decrease in the rate of immigrants reporting no healthcare provision and an increase in reporting of private healthcare provision entitlement. Compared to the Chilean-born, immigrants reported higher rates of use of antenatal and gynaecological care, lower use of well-baby care, and no difference in the use of Pap smears or the number of attentions received in the last three months. Immigrants in the bottom income quintile were four times more likely to report no healthcare provision than their equivalent Chilean-born group (with different health needs, i.e. vertical inequity). Disabled immigrants were more likely to have no healthcare provision compared to the disabled Chilean-born (with similar health needs, i.e. horizontal inequity). Factors associated with immigrants‚Äô access to, and use of, healthcare were sex, urban/rural status, education and country of origin. Conclusion There were significant associations between SES, and access to and use of healthcare among immigrants in Chile and a higher prevalence of no health care provision entitlement among poor and disabled immigrants compared to the Chilean-born. Changing associations between access and use of healthcare and SES among immigrants in Chile over time may reflect changes in their socio-demographic composition or in the survey methodology between 2006 and 2009. Resumen Introducci√≥n La evidencia internacional indica menor acceso y uso de servicios de salud por parte de inmigrantes, pero sus factores desencadenantes var√≠an significativamente dependiendo del contexto. Algunas investigaciones se han desarrollado en este tema en Am√©rica Latina, desde una perspectiva cualitativa. Este estudio cuantitativo explor√≥ el auto-reporte de acceso y uso de servicios de salud de inmigrantes en Chile y los compar√≥ con la poblaci√≥n chilena. M√©todos An√°lisis secundario de datos de encuesta nacional CASEN 2006 y 2009. Inmigrantes fueron comparados con chilenos en caracter√≠sticas demogr√°ficas (edad, sexo, urbano/rural, composici√≥n del hogar, etnia), estatus socioecon√≥mico (educaci√≥n, ingreso, situaci√≥n contractual), tipo de previsi√≥n (p√ļblica, privada, otra, ninguna), y uso de varios servicios de atenci√≥n primaria. An√°lisis descriptivo, estratificado, y modelos de regresi√≥n ponderados para entender factores asociados al acceso y uso de servicios de salud en STATA 11.0. Resultados Se observ√≥ un aumento de reporte de inmigrantes y de la desigualdad en el ingreso de inmigrantes entre 2006 y 2009. Hubo una disminuci√≥n en la tasa de inmigrantes sin previsi√≥n y un aumento en el acceso al sistema privado. Los inmigrantes usaron m√°s frecuentemente la atenci√≥n prenatal y ginecol√≥gica, y menos la atenci√≥n del ni√Īo sano. No hubo diferencia en el uso de citolog√≠a vaginal o el n√ļmero total de atenciones recibidas en comparaci√≥n con los chilenos. Los inmigrantes en el quintil inferior de ingresos reportaron 4 veces m√°s la ausencia de prestaci√≥n de salud que los chilenos (inequidad vertical). Similares resultados se observaron al comparar inmigrantes con discapacidad con chilenos con discapacidad (inequidad horizontal). Los factores asociados con el acceso y uso del servicio de salud por parte de los inmigrantes fueron el sexo, urbano/rural, educaci√≥n y pa√≠s de origen. Conclusi√≥n Se observ√≥ una asociaci√≥n significativa entre estatus socioeconomico, migraci√≥n y acceso y uso de asistencia sanitaria. Los resultados de este estudio pueden deberse a verdaderos cambios en la composici√≥n de los inmigrantes y sus patrones de uso del sistema de salud chileno, pero tambi√©n pueden deberse a cambios en la metodolog√≠a y recolecci√≥n de datos entre encuestas 2006 y 2009. Este aspecto requiere mayor an√°lisis y debate en la regi√≥n. PMID:23158113

    Complementing our recent Washington photometric studies on intermediate age and young Large Magellanic Cloud (LMC) clusters, we present in this work new results for 6 previously unstudied star clusters in the transition range 200-700 Myr. We study NGC 1836, NGC 1860 and NGC 1865, which are projected on the LMC bar; SL 444, also located in the central disc but outside the bar, and LW 224 and SL 548, both located in the outer disc. We derive ages and metallicities from extracted T1 versus C-T1 colour-magnitude diagrams (CMDs), using theoretical isochrones recently computed for the Washington system. For the metallicity determinations, these CMDs are particularly sensitive. We also estimate ages and metallicities of the surrounding fields of NGC 1860 and NGC 1865 by employing the őīT1 index and theoretical isochrones.

  16. Coseismic Deformations Associated with the M=7.2, April 04, 2010, El Mayor-Cucapah Earthquake, Observed from Leveling Survey, Geotechnical Instruments and Water Level Changes in the Mexicali Valley

    2010-12-01

    A first order, second class leveling survey in the Mexicali Valley had been just finished in February 2010, for a project carried out by CICESE (Center for Scientific Research and Higher Education of Ensenada), IMTA (Mexican Institute of Water Technology) and CONAGUA (National Water Comission). Immediately after the M=7.2 earthquake the survey was repeated along 240 km of the profiles in the area of the Cerro Prieto pull-apart basin. The leveling started at the LN00 GPS monument in La Puerta. Overall, an uplift of about 30 cm towards the NE, along the 38 km line, in direction SW-NE is observed with larger gradient to the South of the area. Three subsidence bowls differ from this general pattern. One, south from Ejido Saltillo, with the relative subsidence of 19 cm (considering the displacement at LN00 as zero subsidence), probably reflects subsidence of the Saltillo-Guerrero graben; the second, with a subsidence of 23 cm, is situated south from Ejido Nuevo Leon and can be related to the subsidence triggered by the earthquake in the production area of Cerro Prieto IV. For the third one, with relative depth of 36 cm, situated close to Zacamoto, the southeastern limit cannot be determined, so only a comparison with other methods can explain the origin of this anomaly. All the subsidence bowls are associated with liquefaction observed in the area, with more liquefaction observed close to Zacamoto. Since 1996, CICESE has been operating a network of geotechnical instruments (REDECVAM) for continuous recording of deformation related to tectonic (seismic and interseismic) phenomena, as well as anthropogenic deformation caused by the deep fluid extraction at the Cerro Prieto Geothermal Field. The instruments are installed along the faults which limit the Cerro Prieto pull-apart basin at a distance from 8 to 15 km from the epicenter. Coseismic step-like groundwater level changes ranging from 0.4 to 5.0 meters were recorded at 4 wells in the Cerro Prieto Pull apart-basin equivalent to coseismic volumetric strain field, in the depth of the piezometers, of the order of 10-6 - 10-5. Instruments installed along the ‚Äúcontinuation of the Cerro Prieto‚ÄĚ fault recorded vertical slip of 6 cm, and inclination changes of ~700 microradians, with 10 cm vertical slip measured with a ruler at the surface, Instruments installed on the Saltillo fault recorded up to 3000 microradians change, and vertical and horizontal displacements, measured manually, were of the order of centimeters. The Morelia fault had about 30 cm vertical displacement measured manually. The displacement velocities observed by the instruments are much larger than the aseismic slip velocities or triggered slip velocities observed previously in this area. A comparison between leveling results and geotechnical observations suggests that the magnitude of deformation observed by the instruments is confirmed by the leveling only in the Saltillo-Guerrero graben, thus suggesting that the observed slip triggered on the Morelia and Cerro Prieto faults is shallow.

    RESUMEN Durante la d√©cada de 1990 en los Estados Unidos (EU), el conocimiento sobre el trastorno de estr√©s post-traum√°tico (TEPT) evolucion√≥ de estudios espec√≠ficos en un principio, sobre veteranos de guerra y sobre v√≠ctimas de desastres, a estudios epidemiol√≥gicos m√°s tarde, sin embargo, la epidemiolog√≠a del TEPT en pa√≠ses en desarrollo ha sido un √°rea poco estudiada hasta ahora. Los expertos en el √°rea de trauma han propuesto que los sucesos traum√°ticos que ocurren en la ni√Īez son m√°s perjudiciales para la salud mental que aquellos que ocurren m√°s tarde en la vida. Este trabajo revisa los resultados de un estudio epidemiol√≥gico llevado a cabo en Chile. Espec√≠ficamente, se revisan los resultados sobre las tasas de prevalencia del TEPT, traumas asociados m√°s frecuentemente con √©l, as√≠ como la comorbilidad de este trastorno con otros trastornos psiqui√°tricos a lo largo de la vida. Igualmente se analizaron las diferencias del TEPT en cada sexo, as√≠ como la exposici√≥n a traumas en una muestra representativa de chilenos. Adem√°s se compar√≥ la prevalencia de trastornos psiqui√°tricos en personas que sufrieron su primer trauma durante la ni√Īez, durante la edad adulta, o que no reportaron traumas durante su vida. En estos estudios epidemiol√≥gicos se usaron m√≥dulos del TEPT y trastorno de personalidad antisocial (TPA) de la entrevista diagn√≥stica siguiendo los criterios del DSM-III-R (DIS‚ÄďIII-R). Para evaluar el resto de los trastornos psiqui√°tricos se us√≥ la Entrevista Diagn√≥stica Internacional Compuesta (CIDI). Estos instrumentos fueron administrados en tres ciudades chilenas a 2390 personas mayores de 15 a√Īos. Para estimar los errores est√°ndares (EE) debido al dise√Īo de la muestra y a la necesidad de ajuste se us√≥ el m√©todo Taylor de linearizaci√≥n seriada. Tambi√©n se us√≥ un an√°lisis de regresi√≥n log√≠stica para examinar la relaci√≥n entre el TEPT, los factores demogr√°ficos de riesgo y el tipo de trauma. Adem√°s se utiliz√≥ la regresi√≥n log√≠stica multivariada para evaluar si la relaci√≥n entre el TEPT y el sexo pudiera ser explicada por medio de otros factores de riesgo, as√≠ como para calcular las tasas y la oportunidad relativa (raz√≥n de productos cruzados) de trastornos psiqui√°tricos a lo largo de la vida. El primer an√°lisis arroj√≥ que la prevalencia de TEPT a lo largo de la vida fue de 4.4% (2.5% para hombres y 6.2% para mujeres). De los hechos traum√°ticos reportados, la violaci√≥n sexual tuvo una correlaci√≥n m√°s alta con el TEPT que los dem√°s hechos traum√°ticos. Las mujeres tuvieron m√°s probabilidades de experimentar TEPT que los hombres, despu√©s de controlar la variable asalto violento. El segundo an√°lisis evidenci√≥ que los que hab√≠an sufrido traumas a lo largo de la vida tuvieron mayor probabilidad de tener un trastorno psiqui√°trico en comparaci√≥n con aquellos que no reportaron traumas. Tambi√©n se encontr√≥ que los que sufrieron su primer trauma durante la infancia tuvieron m√°s probabilidad de desarrollar trastornos de p√°nico a lo largo de la vida que aquellos que sufrieron su primer trauma en la edad adulta, independientemente del n√ļmero de traumas que sufrieron y de las diferencias demogr√°ficas. Aunque Chile tiene un contexto hist√≥rico-cultural y una econom√≠a diferente a otros pa√≠ses en los que se ha estudiado anteriormente la epidemiolog√≠a del TEPT, el presente estudio reflej√≥ tendencias similares a las reportadas en estudios previos. Los hallazgos expuestos enfatizan la importancia de investigar la prevalencia del TEPT, los patrones de comorbilidad del TEPT y las diferencias de sexo en la prevalencia del TEPT en diferentes pa√≠ses. Tambi√©n estos resultados sugieren que los sucesos traum√°ticos en la infancia (y no en la adultez) pueden estar relacionados con la ocurrencia de trastornos psiqui√°tricos espec√≠ficos.

  16. "One of the Most Uniform Races of the Entire World": Creole Eugenics and the Myth of Chilean Racial Homogeneity.

    PubMed

    Walsh, Sarah

    2015-11-01

    This article illuminates why Nicol√°s Palacios's 1904 monograph, Raza chilena: Libro escrito por un Chileno i para los Chilenos [Chilean Race: A Book Written by a Chilean for Chileans], is central to the creation of a myth of Chilean racial homogeneity at the turn of the twentieth century. Placing Palacios in the context of Latin American eugenic discourse, it demonstrates how he selected a specific racial origin story in order to accommodate his belief in racial hierarchy while also depicting race mixing in a positive light. Specifically, the article highlights how the myth of Chilean racial homogeneity elided the difference between the term "mestizo," which was applied to people of mixed racial heritage, and "white." I contend that Palacios sought to differentiate Chileans from other Latin Americans by emphasizing their racial distinctiveness. The article therefore highlights that Latin American eugenics was concerned with the creation of national narratives that historicized particular racial mixtures in order to reify and affirm national differences. As such, it connects to literature regarding the history of eugenics, race, nation, and the creation of whiteness. PMID:25733067

  1. Distribution of fallout and environmental radionuclides in ice-free areas of King George Island (Western Antarctica)

    Castillo, Alejandra; Schuller, Paulina; Dercon, Gerd; Nguyen, Minh-Long; Navas, Ana; Ramírez, Paola; López, César

    2013-04-01

    Climate change is progressing at a rate which is several times the global average in Western Antarctica. The Antarctic Peninsula region has experienced a rise of ca. 3¬įC for surface air temperature over the last 50 years; and 87% of 244 glaciers along the west coast of the Antarctic Peninsula have retreated in the last 50 years. Examining the impacts of climate change in Antarctic landscapes, in particular in the soils at the foot of retreating glaciers, can provide a better understanding of the future impacts of climate change on landscape dynamics (including land degradation and resulting changes in land, water and ecosystem quality) in the higher mountainous cold regions of the world. In this paper, results of an exploratory assessment of soil movement and identification of sediment sources and sediment sinks by investigating the distribution of fallout (FRN's) and environmental radionuclides (ERN's) in ice-free areas of King George Island (Western Antarctica) are discussed. This assessment has been carried in the context of an Instituto Ant√°rtico Chileno project, and supported by the IAEA Technical Cooperation, studying land degradation in the cold regions of South America. To this purpose soil profiles were sampled at depth increments at three different control sites. In addition, topsoil (0-1 cm depth) samples were collected from areas identified as potential soil sources and from others identified as sinks of sediments. The soil profiles at the control sites showed distinctive patterns in the depth distribution of the FRN's and ERN's. The 137Cs and 210Pbex activity mass concentration (Bq kg-1) were highest in the topsoil and penetration depth was less than 8 and 25 cm, respectively. The depth distribution of 226Ra and 232Th in the soil profiles was quite homogeneous and greater variation was found for 40K and 238U, possibly related to differences in the mineralogical composition of soils. Average mass activity values of 137Cs and 210Pbex at the source areas were significantly lower than those found at sink areas, suggesting that processes of soil movement are relatively important. The knowledge gained with this research provided baseline information to establish future sampling strategies intended to ensure minimal intervention in the environment. Furthermore, the values of the areal activity density (Bq m-2) of 137Cs, 210Pbex and 7Be in soils and sediments proved the potential for using FRN's to study the redistribution of soil and sediments associated to the process of glacier retreat.

    In spite of abundant archeological material available in Mexico, archeomagnetic studies are extremely scarce. In this work, we conducted systematic archeointensity measurements on some well-known archeological sites in central and eastern Mexico (e.g., Teotihuacan, Templo Mayor among others) to contribute to the relative and absolute chronology of Mesoamerica. Our sampling strategy was guided largely by Linda Manzanilla's detailed study of two of the most important archeological sites in Central Mexico, Teotihuacan, and Templo Mayor, since we sampled only materials that are already studied and provide more or less coherent archeological ages. Moreover, we incorporated data from some Mexican lava flows that erupted during historic times in order to extend the archeointensity master curve for Mexico and Mesoamerica to the present.

  4. Bikes, helmets, and public health: decision-making when goods collide.

    PubMed

    Bateman-House, Alison

    2014-06-01

    How ought public officials address policy choices that entail trade-offs between desirable public health goods? Increasing cycling improves public health both by promoting physical activity and by decreasing vehicle use, thus reducing vehicular emissions. Proponents of bicycle helmets argue that, used properly, they protect individual cyclists; however, there is concern that mandating helmet use may result in a decrease in cycling. In 2012, New York City Mayor Michael Bloomberg opposed a bicycle helmet mandate, concerned that it would have a negative impact on the city's cycling rate, which he had sought to increase. The mayor did not explain his rationale, leaving constituents unsure why he opposed the proposal. This case study underscores the challenge of creating public policy in the context of competing public health goods. PMID:24825196

    Dealing with complex environmental issues frequently inhibits redevelopment of industrial sites in urban settings. In 1993, the City of Chicago (City) Department of Planning and Development, Department of Buildings, and Mayor`s Office joined the Department of Environment to investigate reuse of former industrial/commercial properties (brownfields) suspected of environmental or industrial contamination. The collective result is the Brownfield Program, a three-pronged initiative: Brownfield Pilot Program, Brownfield Forum, and Brownfield Research. Black and Veatch Waste Science, Inc. (Waste Science) carried the Brownfield Program forward by performing a Phase 1 environmental site assessment for the City on one of five pilot sites. Waste Science subsequently completed a Phase 2 environmental site assessment and Phase 3 site remediation at the site. Waste oil and PCB-contaminated soil was removed.

    2010-01-01

    The son of a Lithuanian artist, Antanas Mockus was the president of the National University in Colombia before he became mayor of Bogot√° in 1995. As mayor, he transformed the city into a huge classroom, not only bringing to his administration a new view of governing but also transforming the way people exercised their citizenship. Mockus resorted to a creative communicative and pedagogical effort to change the citizens' hearts and minds in favor of peaceful coexistence and legal compliance. Symbols, metaphors, and humor became the language through which the administration would enforce its measures to deal with urban violence. Unconventional techniques, such as a symbolic vaccine against domestic violence and the use of mimes to control traffic circulation and create a sense of shame among those who committed infractions, helped to stop crime and develop a new sense of citizenship.

El mosaico comprendido por tres posiciones adyacentes tomadas a lo largo de varios semestres nos permite caracterizar la población estelar en la zona que presenta una interacción más importante entre las estrellas masivas y la nube molecular que les dió origen. Los diagramas color-magnitud nos permiten identificar numerosas fuentes con exceso infrarrojo, la mayoría de ellas imposible de detectarse en el rango óptico debido a la fuerte absorción del polvo presente en la región. Es altamente probable que la mayoría de estas fuentes con exceso sean protoestrellas, aunque es necesario realizar espectroscopía infrarroja de las mismas para confirmar su naturaleza.

    Los modelos de Heggie y Ramamani de satélites galácticos en órbitas circulares se basan en una teoría aproximada, por lo que es importante verificar su estabilidad mediante simulaciones numéricas. En esta forma, hemos logrado mostrar que son estables sobre intervalos de tiempo mucho mayores que los que lograron los propios autores de los modelos. Por otra parte, dado que hemos mostrado que el caos es significativo en estos modelos, son un sistema ideal para investigar si, pese a ello, se mantienen estacionarios. Nuestras simulaciones numéricas muestran que, pese al caos, la estacionariedad se mantiene sobre intervalos de centenares de tiempos de cruce del sistema, mucho mayores que los tiempos de Liapunov característicos de sus movimientos caóticos.

    Early efforts for establishing an archeomagnetic reference curve for Mesoamerica failed due to the absence of reliable radiometric dates. Recently, numerous 14C data become available from Central Mexico (Teopancazco and Xalla in Teotihuacan area, Xochicalco, Templo Mayor, Tlatelolco, Cholula and Cacaxtla). In light of these new radiometric and magnetic information, we present here an updated secular variation curve for the last two millennia. In addition, a comparative analysis were carried out with southwest North American data (Lengylel and Eighmy , 2001).

  6. UAVSAR Indication of Right-Lateral Faults in Southern California

    NASA Astrophysics Data System (ADS)

    Donnellan, A.; Parker, J. W.

    2011-12-01

    UAVSAR data have been collected in southern California since spring of 2009. Data started being routinely collected in fall of 2009. Repeat pass interferometry (RPI) products show multiple lineations that strike SE parallel to the main strike of the San Andreas fault (outside of the Big bend). Aside from slip associated with the 2010 M 7.2 El Mayor Cucapah earthquake the lineations, while prominent in the data products, do not indicate large or any offsets on the faults. Faults that are indicated in the data include the Rialto-Colton fault, and the Superstition Hills fault. The RPI products indicate line of site changes between the ground and the instrument, which in this case is on an airborne platform. The flight lines were designed to be generally perpendicular to strike slip motions in southern California, and as a result should show the maximum component of motion toward the instrument. However, it is not possible to decompose horizontal versus vertical motions. Cross sections across these lineations show no offset, except near the 2010 El Mayor-Cucapah rupture, but show substantial differences in range change near the fault as compared to further from the fault. It is likely that different material properties within the fault zone, coupled with either ground-water migration or shaking from the El Mayor-Cucapah earthquake are the cause of these range change differences. We also discuss conjugate faulting associated with the 2010 earthquake and other crustal deformation observed in the Salton Trough.

    The 2010 El-Mayor Cucapah earthquake was the first earthquake to be observed with UAVSAR. UAVSAR observations, GPS time series analysis, and simulations suggest that the fault that ruptured in the earthquake is coupled to the Elsinore, San Jacinto, and San Andreas faults to the north. GPS and UAVSAR observations indicate a zone of shear that extends southward from the Big Bend of the San Andreas fault near Gorman through the San Fernando Valley towards the Newport-Inglewood fault. The zone steps over to the region of the Elsinore or San Jacinto faults, though the partitioning of strain between the two faults is not as clear. State changes in GPS time series data fall in line with the shear zone through the San Fernando Valley and extend northward from the El Mayor-Cucapah earthquake rupture. Seismicity hotspots also indicate elevated earthquake hazard near the San Fernando Valley and in the Inland Empire near the Elsinore and San Jacinto faults. Inversions of GPS velocity vectors favor a fault underlying the shear zone extending from the Big Bend to the Newport-Inglewood fault over substantial slip on the San Andreas fault under north of Los Angeles. Virtual California simulations of southern California are being analyzed for fault activity associated with the identified shear zone and for subsequent earthquakes that may be related to El Mayor-Cucapah type earthquakes in Baja.

  8. First hundred years of research on western Atlantic coral reefs 1850-1950

    The history of research on coral reefs of the Western Atlantic is the history of geology for the same period write small. The inter-related, pioneer researchers were led by the Agassizs, Louis and his son Alexander, who explored and described reefs in Florida and the Bahamas. Among their followers were Alfred G. Mayor the founder-director and premier researcher of the Carnegie Laboratory in the Dry Tortugas; C.F. Hartt who first described southernmost reefs off Brazil; Louis Pourtales whose dredging off the Florida coast stimulated interest in organic limestones; and T. Wayland Vaughan whose research ranged from coral biology to the regional geology and history of reefs. The initial 19th century research was sparked by a combination of practical and scientific questions and the what and where of exploration. To build lighthouses on the wreck-strewn Florida reefs one needs to know their foundations. Is the present-day Florida platform a result of reef growth during subsidence a la Darwin or are the reefs merely icing on a limestone cake. In the second phase of research extending from the early 1900's to 1940's, the singular aspects are two dynamic researchers, Alfred Mayor and T. Wayland Vaughan and the Carnegie Institution's Marine Biology Laboratory in the Dry Tortugas. Mayor through his own biological research and his stimulations of other scientists made the Carnegie Laboratory the world center for reef research. Vaughan pioneered connections between reef-building corals, reef deposits and their logical record.

    Introducci√≥n: la esperanza de vida est√° aumentando y convirti√©ndose en un fen√≥meno caracter√≠stico de los pa√≠ses desarrollados y, cada vez m√°s, de los pa√≠ses en desarrollo, como Brasil. El proceso de envejecimiento produce cambios en algunas funciones fisiol√≥gicas, como la p√©rdida del olfato o gusto o p√©rdida de apetito, entre otros, que terminan alterando la ingesta de alimentos de estos individuos.Objetivos: este estudio tuvo como objetivo evaluar el consumo de alimentos de los ancianos y de los ancianos m√°s longevos en una ciudad del sur de Brasil.M√©todos: un estudio transversal realizado mediante visitas a domicilio en Palmeira das Miss√Ķes - RS, Brasil. Los datos sociodemogr√°ficos, antropom√©tricos y diet√©ticos fueron recogidos a trav√©s de cuestionarios y recordatorio de 24 horas. La adecuaci√≥n de nutrientes se evalu√≥ de acuerdo con las ingestas de referencia en la dieta. Los datos fueron analizados utilizando el software SPSS 18.0.Resultados: el estudio incluy√≥ a 424 adultos mayores, el 84.4% (n = 358) de ellos menores de 80 a√Īos y el 15.6% (n = 66) con m√°s de 80 a√Īos. La ingesta de energ√≠a y prote√≠nas fue insuficiente tanto para j√≥venes adultos como para los m√°s ancianos. El consumo de vitaminas y minerales ha sido insuficiente en todos los adultos mayores a excepci√≥n del hierro, que presentaba una ingesta excesiva. Hubo una diferencia estad√≠sticamente significativa entre las personas de edad y mayores s√≥lo en cuanto al consumo de l√≠pidos y vitamina B12. Conclusi√≥n: la mayor√≠a de los estudios con personas mayores corrobora los resultados obtenidos en este art√≠culo. Una ingesta inadecuada de nutrientes puede dar lugar a deficiencias nutricionales y, por lo tanto, a cambios fisiol√≥gicos y patol√≥gicos que pondr√≠an en peligro la capacidad funcional de los ancianos. El consumo de energ√≠a y de macronutrientes result√≥ insuficiente tanto para los ancianos como para los ancianos m√°s longevos. Adem√°s, el consumo de vitaminas y minerales. PMID:27019240

Todos los ciudadanos menores de 75 a√Īos residentes en Navarra en 2001 fueron seguidos durante 7 a√Īos para conocer su estado vital. El indicador de posici√≥n socioecon√≥mica usado ha sido la superficie de la casa y el n√ļmero de veh√≠culos del hogar. Se han estimado las tasas de mortalidad general y por causa de muerte ajustadas por edad seg√ļn estos indicadores.Resultados. La raz√≥n de tasas por todas las causas de muerte en las categor√≠as inferiores es seg√ļn la superficie de la vivienda de 1,14 (IC 95%: 1,05-1,24) y 1,25 (IC 95%: 1,18-1,32) en mujeres y hombres respectivamente y de 1,46 (IC 95%: 1,36-1,57) y 1,97 (IC 95%: 1,89-2,05) seg√ļn el n√ļmero de veh√≠culos. El sida es la causa de muerte que presenta una mayor diferencia en las tasas de mortalidad entre las personas con menor y mayor bienestar material. Otras causas de muerte con elevada diferencia en las tasas de mortalidad son las enfermedades digestivas y la diabetes mellitus en mujeres y las enfermedades del aparato digestivo y respiratorio en hombres.Conclusiones. La tasa de mortalidad en la poblaci√≥n navarra muestra un gradiente inverso con el bienestar material, a excepci√≥n de algunas localizaciones de c√°ncer.

    We report on a statistical analysis of the engagement in the electoral processes of all Brazilian cities by considering the number of party memberships and the number of candidates for mayor and councillor. By investigating the relationships between the number of party members and the population of voters, we have found that the functional forms of these relationships are well described by sublinear power laws (allometric scaling) surrounded by a multiplicative log-normal noise. We have observed that this pattern is quite similar to those we previously reported for the relationships between the number of candidates (mayor and councillor) and population of voters [Europhys. Lett. 96, 48001 (2011)], suggesting that similar universal laws may be ruling the engagement in the electoral processes. We also note that the power-law exponents display a clear hierarchy, where the more influential is the political position the smaller is the value of the exponent. We have also investigated the probability distributions of the number of candidates (mayor and councillor), party memberships, and voters. The results indicate that the most influential positions are characterized by distributions with very short tails, while less influential positions display an intermediate power-law decay before showing an exponential-like cutoff. We discuss the possibility that, in addition to the political power of the position, limitations in the number of available seats can also be connected with this changing of behavior. We further believe that our empirical findings point out to an under-representation effect, where the larger the city is, the larger are the obstacles for more individuals to become directly engaged in the electoral process.

El estudio de tendencia permiti√≥ conocer un valor promedio de las variaciones de la tasa de incidencia (TI), calculadas por regresi√≥n lineal simple y expresadas como variaci√≥n anual promedio (VAP). Se analizaron el n√ļmero de casos notificados y TI por 100 000 habitantes de todas las formas de TB, los casos de TB pulmonar (TBP) y TBP confirmados por bacteriolog√≠a, total casos por grupos de edad: 0 ‚Äď 14; 15 ‚Äď 29 y mayores de 64 a√Īos, entre el 1¬į de enero de 2000 al 31 de diciembre de 2011. La declinaci√≥n de la TI fue menor al 5% para todas las formas de TB e inferior en las TBP confirmadas bacteriol√≥gicamente. Los casos de TBP y TI m√°s elevadas, se concentraron en el grupo de 15 a 29 a√Īos, con tendencia estable o ligeramente ascendente de la TI en la TBP bacil√≠fera. El mismo comportamiento presentaron los casos de TBP infantil con confirmaci√≥n bacteriol√≥gica. La mayor velocidad de descenso en la TI de la TBP se produjo en este grupo de edad, mientras que en mayores de 64 a√Īos, el descenso fue sostenido en el tiempo. La TB persiste como un riesgo de salud en la RSV, con casos en edades j√≥venes, por lo que sigue siendo necesario fortalecer el control de la TB en esta regi√≥n. PMID:26117604

    Under Mayor Richard M. Daley's leadership, the City of Chicago initiated the Chicago Climate Action Plan (CCAP) to better understand local implications of global climate change in both higher and lower emissions scenarios, reduce greenhouse gas emissions, and implement programs to build future climate change resilience. The City approached this work not only as a way to make Chicago more adaptable in the future, but also to improve Chicago's quality of life today. The Chicago Climate Action Plan adopted stresses the importance of both reducing greenhouse gas emissions in Chicago and preparing for climate changes that may be unavoidable. Building off of the City's significant environmental programs and projects, and based on our analyses of the climate effects and impacts that improved the scientific understanding of future climate change impacts on Chicago, the City then developed a set of climate change adaptation strategies, resulting in the City of Chicago Climate Change Adaptation Summary. This document includes prioritization of climate change adaptations based on relative risk as well as framework strategies for those tactics categorized as "must do/early action." In early 2008, The Mayor's Office asked five Commissioners from its Green Steering Committee to chair adaptation work groups including: extreme heat; extreme precipitation; buildings, infrastructure and equipment; ecosystems; and leadership, planning and communications. Working with staff from relevant departments, sister agencies and other stakeholders, these work groups developed 39 basic adaptation work plans, including plans for enhancing the City's existing projects and programs that relate to climate change adaptation. Climate change adaptation work will be on-going in City Departments under the Mayor's Office leadership. The City intends to continually monitor and improve its response to climate change, resulting in an improved quality of life for Chicago residents.

  17. From protest to programs: neighborhood associations in a Brazilian municipality.

    1992-01-01

    The examples of community participation and organization in Brazil reflect the benefits to health and education programs and land entitlement. The community and government were working together toward self-improvement. An alliance was formed between neighborhood groups and a reform mayor. The result was an end to clientelism, stronger community organization, and local participation in designing and implementing development programs. The neighborhood groups were located in Cambe, which is a region located within the metropolitan area of Londrina, the 3rd largest city in southern Brazil. Mechanization of agriculture and extensive cattle ranching had caused migration into the area. Population increased 60% during the 1980s. The poorest neighborhoods were Jardim Tupy, Santo Amaro, and Novo Bandeirantes. Jardim Tupy was the poorest, and in 1980 a neighborhood association was formed to demand infrastructure and public services. The clientelism mayor and national government refused aid. When the association sued over a motor vehicle accident involving farm workers living in the community and won, there was momentum to change city hall. Support was given to the reform mayor who won and agreed to community demands for a community garden. The garden became a model for 14 others in Cambe and led to a strong neighborhood association which learned the strength of unity. The mayor rewarded good neighborhood organization with increases in public goods and services. The Catholic Church became involved in Jardim Tupy with a Pastoral of the Child program to reduce infant and child mortality rates. Health improvements in the community are attributed to the neighborhood association, the Pastoral of the Child, the local Catholic parish, and a thaw in the relationship with local government. The residents learned the limits of local government and the lessons of self-help. Santo Amaro, while not as well organized as Jardim Tupy, was successful at overcoming the lack of resources. novo Bandeirantes was successful in direct action to design and implement public programs. This involved survey in the socioeconomic conditions of the neighborhood, obtaining funding for and building latrines, and helping landholders gain title to their lands. PMID:12286184

    Oxytocinase has been reported to hydrolyse the peptide hormone oxytocin (OT). We have previously described changes in oxytocinase activity in human breast cancer, where a highly significant increase occurred in tumoral tissue. In the present work, we analysed oxytocinase activity in serum of rats with breast cancer induced by N-methyl-nitrosourea (NMU). We also correlated these data with the number and size of tumors and the body weight of the animals to evaluate the putative value of this activity as a biological marker of the disease. Our results confirm the involvement of OT in carcinogenesis and suggest a mayor role for oxytocinase activity in the development of breast cancer. PMID:15234194

    Three cases of secular variation of Mexico will be analyzed. The first is the preliminary results of the record of the transition Bruhnes-Matuyama in a paleosol sequence. The second is the research of a rock shelter since late Pliocene-early Holocene to Posclassic (AD 900-1527). Finally the improvement of the first archaeomagnetic secular variation curve of Mesoamerica from 1973 to 2012 with the inclusion of new results like La Ciudadela and Teopancazco of Teotihuacan, Tlatelolco and Templo Mayor of Mexico City and Tula. Our results will be compared with previous records from lake sediments and volcanic rocks, the models available like CALS*K or other published curves.

    Between around 1491 and 1513, three draft general ordinances were drawn up to regulate Castilian medical practitioners (physicians, surgeons and apothecaries). None were finally enacted because of disagreement among those responsible for their drafting, namely the court-appointed physicians, mayors with exclusive jurisdiction over these activities, and the Royal Council, which was the supreme organ of governance and justice of the Crown of Castile. Consequently, health activities could not be standardized throughout the territory of Castile, and the court-appointed physicians continued to regulate them locally in a unilateral and uncoordinated manner.

    1982-01-01

    Band model theories are used to calculate the transmission of the methane spectrum. In a band model the monochromatic absorption coefficient over a small wavelength interval is replaced, and an average pressure coefficient is introduced. Two main types of band models were developed. The first is the 'regular' band model, in which the lines in a band are presumed evenly spaced; this is also called the Elsasser band model. In the second type of band model, the lines are randomly spaced; this is often referred to as the Mayor-Goody band model. The methane spectrum is sufficiently irregular that the second band model, the irregular band model, should apply.

    New paleomagnetic data from Permo-Triassic and Late Cretaceous rocks yield a consistent trend of vertical-axis-tectonic-rotations which are consistent with the Central Andean Rotation Pattern (CARP). However, three sites in the Tuina Formation and one site in the Purilactis Group record large rotations (80¬į). These mayor rotations are probably due to dextral-transpressive deformation occurring in close relation with the Incaic tectonic phase. Consequently, it is possible to infer that previous tectonic phases Peruvian and K-T would not have produced significant tectonic rotations in the area.

    This year marks the 20th anniversary of the first definitive detection of an exoplanet orbiting a Sun-like star by Mayor and Queloz (1995). Almost 2000 exoplanets have been discovered since this breakthrough, but many fundamental questions remain open despite the enormous progress: How common are analogues of the Solar System? How do planets form and evolve? What is the relationship between stars and planets? We are observing stars that are near-perfect matches to the Sun to provide new insights into the above questions, thus exploring the planet-star connection with unprecedented precision.

The GPS and seismic data collected during the 2011 Tohoku-Oki (Japan) and the 2010 El Mayor-Cucapah (Mexico) earthquakes are analyzed by using a tightly-coupled integration. The performance of the integrated results is validated by both time and frequency domain analysis. We detect the P-wave arrival and observe small-scale features of the movement from the integrated results and locate the epicenter. Meanwhile, permanent offsets are extracted from the integrated displacements highly accurately and used for reliable fault slip inversion and magnitude estimation. PMID:24284765

    A sample of 323 residents of New Jersey stratified by neighborhood quality (excellent, good, fair, poor) was gathered to determine if trust in science and technology to protect public health and environment at the societal scale was associated with trust of the local officials, such as the mayor, health officer, developers, mass media, and legislators who are guardians of the local environment. Societal (trust of science and technology) and neighborhood (mayor, health officer) dimensions of trust were found. These societal and neighborhood trust dimensions were weakly correlated. Respondents were divided into four trust-of-authority groups: high societal-high neighborhood, low societal-low neighborhood, high societal-low neighborhood, and low societal-high neighborhood. High societal-high neighborhood trust respondents were older, had lived in the neighborhoods for many years, were not troubled much by neighborhood or societal environmental threats, and had a strong sense of control over their environment. In strong contrast, low societal-low neighborhood trust respondents were relatively young, typically had lived in their present neighborhood for a short time, were troubled by numerous neighborhood and societal environmental threats, did not practice many personal public health practices, and felt little control over their environment.

    2004-12-01

    For the first time results of an archaeomagnetic study of mural paintings and unburned lime-plasters from Mesoamerica are presented. The magnetic measurements show that at least four murals (sites: Cacaxtla, Cholula and Templo Mayor) retain a remanent magnetization carried by a mixture of hematite and magnetite grains. In most specimens, a characteristic magnetization is successfully isolated by alternating field demagnetization. The mean directions are reasonably well determined for each murals and within the range of secular variation during the last centuries. Studied Mesoamerican murals apparently retain the direction of the magnetic field at the time they were painted and are therefore an invaluable source of information concerning its secular variation. Lime-plaster samples were selected from two archaeological excavation projects in the Teopancazco residential compound of Teotihuacan and the large multi-stage structure of Templo Mayor in Tenochtitlan, where chronological information is available. The intensity of remanent magnetization and low-field susceptibility are weak reflecting low relative content of magnetic minerals. NRM directions are well grouped and alternating field demagnetization shows single or two-component magnetizations. Rock-magnetic experiments point to fine-grained titanomagnetites with pseudo-single domain behavior. Anisotropy of magnetic susceptibility measurements document a depositional fabric, with normal to free-surface minimum AMS axes. Characteristic mean site directions were correlated to the paleosecular variation curve for Mesoamerica. Our results suggest that archaeomagnetic dating can be applied to mural paintings and lime-plasters, which are materials widely employed in Mesoamerica.

  5. Emerging techniques to quantify 3D ground deformation using high resolution optical imagery and multi-temporal LiDAR

    NASA Astrophysics Data System (ADS)

    Leprince, S.; Ayoub, F.; Conejo, B.; Avouac, J.

    2012-12-01

    We demonstrate how 3D ground deformations, involving different types of geomorphological processes, can be recovered using three different techniques. First, we focus on the availability of high resolution imagery such as provided by the Quickbird or Worldview satellites, to reconstruct the 3D displacement field induced by the 2010 El-Mayor Cucapah earthquake. Full-field ground deformation is recovered using sub-pixel image matching and triangulation on a set of images acquired before the earthquake, and on a set of images acquired after the earthquake. This technique is implicitly equivalent to reconstructing two elevation models, before and after the earthquake, using stereoscopy, and matching them. Second, we show that the ground deformation recovered for the El-Mayor Cucapah earthquake using multi-angle and multitemporal optical imagery can also be recovered using image correlation techniques applied to gridded LiDAR data. However, we also show that image correlation techniques applied to LiDAR data fail when the topography to be analyzed is too smooth, as is often the case on sand dunes. Therefore, we finally introduce a point-cloud matching technique based on the Free Form Deformation (FFD) framework, which delivers promising results even when applied to smooth and poorly textured LiDAR data. In particular, we study a time series of LiDAR data acquired above the White Sand Dunes, NM, and we derive their migration field from 2007 to 2010.

  6. Stress- and structure-controlled anisotropy in a region of complex faulting‚ÄĒYuha Desert, California

    Cochran, E. S.; Kroll, K. A.

    2015-08-01

    We examine shear velocity anisotropy in the Yuha Desert, California using aftershocks of the 2010 M7.2 El Mayor-Cucapah earthquake. The Yuha Desert is underlain by a complex network of right- and left-lateral conjugate faults, some of which experienced triggered slip during the El Mayor-Cucapah earthquake. An automated method that implements multiple measurement windows and a range of bandpass filters is used to estimate the fast direction (ŌÜ) and delay time (őīt) of the split shear waves. We find an average ŌÜ oriented approximately north-south suggesting it is primarily controlled by the regional maximum compressive stress direction. However, the spatial variability in ŌÜ reveals that the fault structures that underlie the Yuha Desert also influence the measured splitting parameters. We infer that the northeast- and northwest-oriented ŌÜ reflect shear fabric subparallel to the conjugate fault structures. We do not observe a simple correlation between őīt and hypocentral distance. Instead, the observed spatial variation in őīt suggests that near-source variation in anisotropic strength may be equal to or more important than effects local to the station. No temporal variation in splitting parameters is observed during the 70-day period following the main shock. In this region of complex faulting, we observe a spatially variable pattern of anisotropy that is both stress- and structure-controlled. This study suggests that shear fabric can form even along short, discontinuous fault strands with minimal offset.

    Kapitza-Dirac-Talbot-Lau interferometry (KDTLI) has recently been established as an ideal method to perform quantum matter wave experiments with large, highly polarizable molecules in an unprecedented mass range of beyond 1000 atomic mass units [1]. Since the interference visibility reveals important information on the properties of the examined particles, such as their mass and polarizability, we identified KDTLI as a valuable tool for precision metrology. We demonstrate that quantum interferometry can therefore also serve as a powerful complement to mass spectrometry [2], in particular in cases where fragmentation may occur in the detector. Our new method is applicable to a wide range of molecules and is particularly valuable for characterizing neutral molecular beams. [1] S. Gerlich, L. Hackerm"uller, K. Hornberger, A. Stibor, H.

  9. Politics, Police Accountability, and Public Health: Civilian Review in Newark, New Jersey.

    PubMed

    McGregor, Alecia

    2016-04-01

    Police brutality, a longstanding civil rights issue, has returned to the forefront of American public debate. A growing body of public health research shows that excessive use of force by police and racial profiling have adverse effects on health for African Americans and other marginalized groups. Yet, interventions to monitor unlawful policing have been met with fierce opposition at the federal, state, and local levels. On April 30, 2015, the mayor of Newark, New Jersey signed an executive order establishing a Civilian Complaint Review Board (CCRB) to monitor the Newark Police Department (NPD). Using a mixed-methods approach, this study examined how advocates and government actors accomplished this recent policy change in the face of police opposition and after a 50-year history of unsuccessful attempts in Newark. Drawing on official public documents, news media, and interviews conducted in April and May 2015, I propose that: (1) a Department of Justice investigation of the NPD, (2) the activist background of the Mayor and his relationships with community organizations, and (3) the momentum provided by the national Black Lives Matter movement were pivotal in overcoming political obstacles to reform. Examining the history of CCRB adoption in Newark suggests when and where advocates may intervene to promote policing reforms in other US cities. PMID:26661578

The Baths have been marketed as a health resort to lure visitors. Dr Stockmann alerts officials about the problem and assumes that they will close the Baths until it is corrected. He is met with fierce resistance, however. His brother, the town's mayor, favors keeping the Baths open and correcting the problem gradually. He advances multiple arguments that appeal to the economic interests of the town and Thomas's role-related obligation as a citizen. His wife, Katherine, wants him to cooperate with the mayor. She marshals several arguments that appeal to his obligations as a father. This paper reconstructs and examines the competing arguments, shows how Ibsen's play has both contemporary relevance and moral depth, and demonstrates how Dr Stockmann's responses can be interpreted as an argument that complying with his duties to protect the public health do not force him to renege on his core commitments as a parent and as a citizen.

    Wonju is the first municipality in the Republic of Korea to fund the Healthy City project through municipal revenues from the local tobacco consumption tax. We investigated the process of the local tobacco consumption tax being approved as the main source of financing for the local Healthy City project. We also examined the sustainability and sufficiency of the funding by looking at the pricing policies instituted for cigarettes, smoking prevalence, cigarette consumption and revenues from local tobacco consumption as well as the budgetary allocations among programs in the city. The strong initiative of the mayor of Wonju was one of the factors that enabled the earmarking of the local tobacco consumption tax for the Healthy City Wonju project. He consulted academic counselors and persuaded the municipal government and the City Council to approve the bill. Despite the increasing price of cigarettes in Korea, adequate funding can be sustained to cover the short-term and mid-term programs in Wonju for at least 5 years of the mayor's term, because the smoking rate is persistently high. Analyzing the effects of strong leadership on the part of local authorities and the balance between revenues from the tobacco tax and the prevalence of smoking in the face of anti-smoking policies would be helpful for other countries and communities interested in developing sustainable Healthy Cities projects.

    RESUMEN. Se ha considerado un proceso de coagulaci6n de granos en nubes colapsantes de diferentes metalicidades. Se aplicaron los calculos al intervalo de densidades n = lO to , forrespondiendo a la fase isotermica de contracci6n de nubes. A lo largo de esta fase en el colap- so, la temperatura es por lo tanto constante, en donde se alcanza T Q lOKpara nubes de metalicidad solar y T 100 K para nubes de baja metalicidad. El tamano final del grano es mayor para las mayores metali- cidades. ABSTRACT. A process of grain coagulation in collapsing clouds of different metallicities is considered. The calculations are applied to the density range n = 1O to , corresponding to the isothermal phase of cloud contraction. Along this phase in the collapse, the temperature is thus a constant, where T % 10 K for solar-metallicity clouds, and T % 100 K for low metallicity clouds is reached. The final grain size is larger for the higher metallicities. Keq : INTERSTELLAR-CLOUDS - INTERSTELLAR-CRAINS

    2007-01-01

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K. Kelly. The Chilean teachers are visiting Magdalena while they are on their Southern Hemisphere summer vacation, and Magdalena's schools are in session. Two Magdalena teachers, Joleen Welborn and Sandra Montoya, will visit San Pedro in June, while they are on summer vacation and the Chilean schools will be in session. Dr. Eduardo Hardy, the AUI/NRAO representative in Chile, will accompany the Chilean teachers on their visit, which has been coordinated by Harrison. "ALMA is a groundbreaking example of the type of international cooperation that marks the future of astronomy. We are especially pleased to sponsor a program that brings together two communities that both enjoy proximity to world-class astronomical research facilities," said Dr. Fred K.Y. Lo, NRAO Director. "While separated by many miles, San Pedro de Atacama and Magdalena have much in common. Both are small communities in high desert environments, and both are next to telescopes where the world's astronomers will be making many exciting discoveries in the coming decades. Bringing these two communities together will advance education and international understanding," Harrison said. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

    Pore pressure built up during an earthquake and the hazard associated with soil liquefaction present a major challenge for our society, as has been dramatically illustrated by recent large events (e.g. the 2011 Tohoku-oki, Japan, earthquake). There is consensus among scientists that a better assessment of the liquefaction risk requires a better understanding of the coupling between pore pressure and ground motion time histories. There is a basic need to investigate coupling as a function of the frequency content of the ground motion. The 2010 M7.2 El Mayor-Cucapah event has provided a remarkable opportunity to investigate and model the coupling. The event was well recorded at the NEES@UCSB Wildlife station located 110 km from the hypocenter. The station is equipped with three-component strong-motion accelerometers at the surface and in boreholes at various depths and with pore pressure transducers located in a saturated, liquefiable layer. The recorded pore pressure and ground motion time histories both have frequency content that is a function of time. We have applied a wavelet decomposition technique to the El Mayor ground motion and pore pressure data, looking for a linear relationship between the signals. The analysis shows that the early P-wave accelerations (vertical component) initiate pore pressure response. However, the pore pressure records contain a low-frequency component that dominates the signal with no corresponding low-frequency component in the ground motion signals recorded near-by. Although uncommon, a similar behavior has been also reported in the literature for pore pressure signals recoded during the 1980 Mammoth Lakes, California, earthquake. We have extended this work to the analysis of 4 other seismic events that have induced an increase in pore pressure at WLA. As the response of pore pressure is potentially a local phenomenon, we have restricted our analysis to recordings from the same site. These events include the M5.8 Ocotillo earthquake that was the largest aftershock of El Mayor.

  18. Quartz Resorption as a Geospeedometer in Peralkaline Rhyolites

    2010-12-01

    Magma ascent rate affects eruptive style and intensity as it determines time available for syn-eruptive crystallization, vesiculation and permeable gas loss. The width of hornblende reaction rims has previously been used to estimate ascent rates for eruptions of andesitic volcanoes. Reactions between quartz and the coexisting melt could provide a similar proxy for peralkaline silicic magmas. Mayor Island, a peralkaline rhyolitic volcano in New Zealand, was used as a case study to investigate the use of quartz resorption as a geospeedometer. During the last 130 ka, Mayor Island has exhibited a wide range of eruptions, both with regards to intensity and volume. Previous studies have determined the pre-eruptive temperature to be around 750¬įC and pressure to be 100-125 MPa, and proposed that the magma chamber is saturated in water (Barclay et al., 1996). Neither the composition of the magma (72-74 wt% SiO2) nor the water content (4.4 wt%) have changed significantly between the different styles of eruptions, and the wide range of eruptive style was therefore attributed to variations in the ascent rate. In general, the quartz phenocrysts from the effusive eruptions are rounded, whereas those from the explosive eruptions are euhedral. Scaillet and Macdonald (2001) established that there are realistic conditions for which quartz in peralkaline rhyolites goes from stable to unstable to stable again during decompression. In this study, the stability fields of quartz were determined for a Mayor Island magma composition using an externally heated cold-seal pressure vessel. The rate of quartz resorption was assessed by carrying out time-series experiments. The pre-eruptive conditions were determined to be about 700-750¬įC from feldspar thermometry and phase equilibria. The results indicate that the magma was water under-saturated and consequently stored at higher pressures than previously calculated. The time-series experiments imply that magma that erupt explosively did not spend more than a couple of days at pressure between 150 and 50 MPa. REFERENCES Barclay, J., Carroll, M. R., Houghton, B.

    Using relative astrometry and ground based imaging, we study nearby stellar multiple systems in order to detect the astrometric signal of exoplanets around one of the stellar components. We suppress differential chromatic refraction effects by observing in the near infrared with a narrow-band filter and by choosing an iterative calibration strategy (using a stellar cluster) we obtain a precision down to 100 őľas in our relative astrometric measurements. This allows us to study the occurence and properties of exoplanets in nearby (less than 100 pc) stellar multiple systems. While trying to detect the astrometric signal of the exoplanet orbiting HD19994 A (Mayor et al. 2004), we detected the astrometric signal of a further object around the B component. This astrometric detection is confirmed by speckle interferometry and follow-up radial velocity (RV) observations. Thus, HD19994 is an exoplanet host-triple system.

    In this work we report an updated study of the sea level variations for the Mediterranean sea for the period from October 1992 to January 2008. The study addresses two mayor issues: (i)The analysis of the spatial and temporal variability of sea surface height (SSH) from radar altimetry measurements (from TOPEX/Poseidon (T/P) + Jason-1, etc.). We use EOF analysis to explain most of its interannual variation, and how the different basins interact. (ii) The analysis of dynamics and balance of water mass transport for the whole period. We estimate the steric SSH by combining the steric SSH estimated from temperature and salt profiles simulated by the ECCO model with time-variable gravity (TVG) data (from GRACE) for the Mediterranean Sea. The estimated steric SSH together with the SSH obtained from altimetry allow for a more realistic estimation of the water mass variations in the Mediterranean for the whole period.

    We determine the fraction of F, G, and K dwarfs in the solar neighborhood hosting hot Jupiters as measured by the California Planet Survey from the Lick and Keck planet searches. We find the rate to be 1.2% {+-} 0.38%, which is consistent with the rate reported by Mayor et al. from the HARPS and CORALIE radial velocity (RV) surveys. These numbers are more than double the rate reported by Howard et al. for Kepler stars and the rate of Gould et al. from the OGLE-III transit search; however, due to small number statistics these differences are of only marginal statistical significance. We explore some of the difficulties in estimating this rate from the existing RV data sets and comparing RV rates to rates from other techniques.

    The Air borne Multi AXis DOAS (AMAXDOAS) was successfully operated during two connected campaigns in summer 2002 and winter 2003. It was installed aboard the DLR Falcon. The campaigns reached from the Arctic to the Tropics. They were part of the national SCIAMACHY validation program and therefore revered to as SCIA values. Together with the AMAXDOAS the OLEX (Lidar) and the ASUR (Microwave) were operated onboard the aeroplane. With up to ten different viewing angles, looking above and below the aircraft, AMAXDOAS can distinguish between the corresponding columns for many trace gases e.g.: BrO, H2O, HCHO, NO2, O3, SO2. For SCIAMACHY validation the separation of tropospheric and stratospheric columns is of mayor interest. In this article first steps towards the separation are shown.

    Cardiac failure is still one of the mayor reasons for death in the Western population but the pathophysiology of the molecular processes in the heart is far from being completely understood. Therefore further basic research is necessary. With recent developments of optical technologies novel tools to investigate cardiac physiology and pathophysiology became available. They comprise non-linear imaging techniques such as second harmonic generation imaging and fast two-photon excitation imaging of cardiac tissue. In addition, high-speed multi-beam two-photon imaging as well as ultra-high speed single beam single photon 2D-confocal imaging offer novel approaches to study cellular and subcellular signalling events in cardiac tissue and/or single cardiac myocytes. Here we introduce and discuss these new technologies and their practical application to study cardiac physiology and pathophysiology.

    1988-08-01

    Public reaction to the risk from radon varied widely in three communities chosen for qualitative analysis. In Boyertown, PA, some residents were very alarmed, but most were apathetic toward this newly identified environmental risk. In Clinton, NJ, residents were concerned and worked with the mayor and the state to determine whether they were at risk and to disseminate information about mitigation of high indoor radon levels. Residents in Vernon, New Jersey were very alarmed and actively opposed the state's decision to site low-level radium wastes there. The qualitative study examines why reactions differed among the three communities, and extracts lessons for communicating about the risk from radon. These lessons should apply to communicating about other environmental hazards to individuals and communities.

    Impairment of intelligence in Duchenne muscular dystrophy (DMD) patients was described by Duchenne de Boulogne himself in 1868. Further studies report intelligence disorders with mayor impairment of memory. The aim of the present study was to assess the presence of affective and personality disorders in a group of children affected by DMD. Twenty six male DMD patients, mean age eleven and four months years old, were assessed for their affective and personality disorder. Only eight subjects had a total IQ below average with major difficulties in verbal and visual-spatial memory, comprehension, arithmetic and vocabulary. All the subjects presented some disorders: tendency to marginalization and isolation, self-depreciation, sense of insecurity, hypochondriac thoughts and marked state of anxiety. These disorders are often a dynamic prolongation of a psychological process which starts when the diagnosis is made and continues, in a slow and latent fashion, throughout the evolution of the disease.

    Previous radial velocity observations of HD6434 (Mayor et al. 2004, cat. J/A+A/415/391) were undertaken with the CORALIE spectrometer mounted on the 1.2m Euler Swiss telescope at La Silla. Those observations were conducted as part of the CORALIE exoplanet search program (Udry et al. 2000, cat. J/A+A/356/590). We continued to monitor HD6434 using CORALIE to improve the Keplerian orbital solution and provide an accurate transit ephemeris. The complete data set of 137 measurements is shown in Table2 including previously acquired measurements and 59 new measurements. These new measurements extend the overall time baseline for the radial velocity observations by a factor of ~3.6, for a total baseline of ~15 years. (1 data file).

    Burning a county's or municipality's refuse and turning is into electricity should take off as a major growth industry, and capital investment in such plants over the next 10 years could reach $20 billion. Charles River Associates predicts that by 1995 some 75 incinerators will be in operation, taking in annual revenues of $4 billion. Unlike the ill-starred attempts to turn profits into trash in the 1970s, the new plants will use a proven technique called mass burning. While there is some concern about dioxin emissions, these plants emit negligible pollution when properly run. Since Americans throw away 170 million tons of household garbage annually - and since the country is fast running out of landfill sites - the refuse problem is especially acute in heavily populated areas. The biggest prizes, of course, for the refuse-to-energy companies will be the big cities; Mayor Koch wants five for New York City, one for each borough.

  12. Why 400 Years to Discover Countless Planets?

    Carr, Paul H.

    2011-04-01

    In 1584, Dominican monk Giordano Bruno envisioned the stars as "countless suns with countless earths, all rotating around their suns." Searching for intellectual freedom, he fled his native Italy to Protestant Switzerland and Germany, but in 1600 the Roman Inquisition condemned him for heresy. He was burned at the stake. Fast-forwarding to 1995, the Swiss astronomers Michel Mayor and Didier Queloz announced the discovery of a planet orbiting a star similar to our sun (51 Pegasi). In 2010, 500 planets had been found orbiting 421 stars. On Feb 2, 2011, NASA announced 1200 planet candidates. It took 400 years for telescope technology to advance and for Copernicus, Galileo, Newton, Bradley, and Foucault to make major contributions, culminating in today's astrophysics with digital imaging and processing. Contrasting with Bruno, in 2010 Dominican Francisco Ayala, who had been president of the Sigma Xi and AAAS, won the 1.6M Templeton Prize for affirming life's spiritual dimension.

    Se presentan observaciones espectrosc√≥picas de 32 blue stragglers en 6 c√ļmulos abiertos. Un m√≠nimo de 4 espectros por objeto fueron obtenidos en base a los cuales se determina tipo espectral, velocidad radial y velocidad de rotaci√≥n proyectada. La comparaci√≥n con la velocidad media de los c√ļmulos asegurar√≠a una alta probabilidad de pertenencia para la mayor√≠a de los objetos estudiados. Un an√°lisis de variabilidad conduce a la detecci√≥n de un nuevo blue straggler binario en el c√ļmulo NGC 6530 adem√°s de otras probables binarias. En base a la frecuencia de binaridad y a la distribuci√≥n de velocidades rotacionales se discuten los probables mecanismos de formaci√≥n de los blue stragglers.

    Impairment of intelligence in Duchenne muscular dystrophy (DMD) patients was described by Duchenne de Boulogne himself in 1868. Further studies report intelligence disorders with mayor impairment of memory. The aim of the present study was to assess the presence of affective and personality disorders in a group of children affected by DMD. Twenty six male DMD patients, mean age eleven and four months years old, were assessed for their affective and personality disorder. Only eight subjects had a total IQ below average with major difficulties in verbal and visual-spatial memory, comprehension, arithmetic and vocabulary. All the subjects presented some disorders: tendency to marginalization and isolation, self-depreciation, sense of insecurity, hypochondriac thoughts and marked state of anxiety. These disorders are often a dynamic prolongation of a psychological process which starts when the diagnosis is made and continues, in a slow and latent fashion, throughout the evolution of the disease.

    2015-05-01

    Fear-based public health campaigns have been the subject of an intense moral and empirical debate. We examined how New York City, under Mayor Michael Bloomberg, used fear-based appeals to confront three challenges to public health: high rates of tobacco use, obesity, and HIV infection. New York City's use of this type of messaging may have set a precedent. Other state and local health departments will have to navigate how and whether to use fear in a context where it is possible to assert that it can serve the interests of public health. But this will not reduce the need to carefully balance efficacy, uncertainty, stigma, marginalization, emotional burdens, justice, community participation, and scientific credibility. PMID:25941287

    Agave turneri, a new species of Agave from the Sierras Cucap√° and El Mayor in northeastern Baja California, Mexico, is a medium-sized species that does not produce offsets, has a relatively short and narrow panicle, and has a distinctive flower structure. The closest relatives to this new species are Agave moranii, which occurs approximately 200 km to the south of the type locality, and A. deserti var. simplex, which occurs in Arizona and California. This new species is a narrow endemic restricted to specific granodiorite and tonalite habitats in a hyperarid environment. Agave turneri appears to be a critically endangered owing to its habitat preference for specific types of granite in the Sierra Cucap√°, threats due to prolonged drought and global change, and its close proximity to the Mexicali metropolitan area.

    Cross-sectional scanning tunneling microscopy was used to study at the atomic scale the double capping process of self-assembled InAs/InP quantum dots (QDs) grown by molecular beam epitaxy on a (311)B substrate. The thickness of the first capping layer is found to play a mayor role in determining the final results of the process. For first capping layers up to 3.5 nm, the height of the QDs correspond to the thickness of the first capping layer. Nevertheless, for thicknesses higher than 3.5 nm, a reduction in the dot height compared to the thickness of the first capping layer is observed. These results are interpreted in terms of a transition from a double capping to a classical capping process when the first capping layer is thick enough to completely cover the dots.

    This paper describes the investigation by a British local government board inspector in 1902, H Timbrell Bulstrode, into the cause of an outbreak of enteric fever after a mayoral banquet given at Winchester. This investigation helped to confirm the role of oysters as an agent of transmission of typhoid fever. The data are also reanalysed using a modern approach, which confirmed the role of oysters (odds ratio = 11.2, 95% CI 2.5 to 50.1). This episode is illustrative of the role of British public health inspectors at the turn of the 20th century as well as of the conditions in which the technique of investigating outbreaks of food borne diseases using a standardised menu was developed. Current methods of outbreak investigations that differ from Bulstrode's pioneering work are also discussed. PMID:15650138

    We study the contractile dynamics of a collection of active polar filaments, such as actin, on a two dimensional substrate, using a continuum hydrodynamic description in the presence of spatiotemporal noise. The steady states, characterized by a variety of phases generically consisting of a transient collection of inward pointing asters. We next study the dynamics of particles advected along these active filaments. This is relevant to the dynamics and organization of a large class of cell surface molecules. We make several predictions regarding the statistics of fluctuations of these passive advective particles which we confirm using fluorescence based experiments. We then show how such active patterning of filaments can give rise to membrane stresses leading to membrane shape deformations. In collaboration with Kripa Gowrishankar and Satyajit Mayor.

    Following the Department of Energy's announcement in April 1985 that three Tennessee sites were to be considered for the Monitored Retrievable Storage facility, Governor Lamar Alexander initiated a review of the proposal to be coordinated by his Safe Growth Team. Roane County and the City of Oak Ridge, the local governments sharing jurisdiction over DOE's primary and secondary sites, were invited to participate in the state's review of the MRS proposal. Many issues related to the proposed MRS are being considered by the Governor's Safe Growth Team. The primary objective of the Clinch River MRS Task Force has been to determine whether the proposed Monitored Retrievable Storage facility should be accepted by the local governments, and if so, under what conditions. The Clinch River MRS Task Force is organized into an Executive Committee cochaired by the Roane County Executive and Mayor of Oak Ridge and three Study Groups focusing on environmental (including health and safety), socioeconomic, and transportation issues.

    Semi-insulating InP is most commonly obtained by doping with the deep acceptor iron to compensate the shallow donors which otherwise render the material n-type conducting. As the Fermi level in semi-insulating InP is closed to the iron acceptor level, both charge states - Fe{sup 2+} as well as Fe{sup 3+} corresponding to the acceptor level occupied unoccupied by an electron - are present. Mayor et al.(1) presented a method based on absorption measurements in the nearbandgap region of InP to determine the concentration of both charge states separately. In this paper we compare iron concentrations obtained by this method with the results from intracenter absorption, DLTS, EPR, Hall effect measurements and glow discharge mass spectroscopy. We present a new calibration for the optical absorption cross sections.

    Airborne lidar (light detection and ranging) topography, acquired before and after an earthquake, can provide an estimate of the coseismic surface displacement field by differencing the preevent and postevent lidar point clouds. However, estimated displacements can be contaminated by the presence of large systematic errors in either of the point clouds. We present three-dimensional displacements obtained by differencing airborne lidar point clouds collected before and after the El Mayor-Cucapah earthquake, a Mw 7.2 earthquake that occurred in 2010. The original surface displacement estimates contained large, periodic artifacts caused by systematic errors in the preevent lidar data. Reprocessing the preevent data, detailed herein, removed a majority of these systematic errors that were largely due to misalignment between the scanning mirror and the outgoing laser beam. The methodology presented can be applied to other legacy airborne laser scanning data sets in order to improve change estimates from temporally spaced lidar acquisitions.

    This paper analyzes the outcomes of an innovative technology experience for students and teachers (ITEST) project, Mayor's Youth Technology Corps (MYTCs) in Detroit, MI, which was funded by the NSF ITEST program. The MYTC project offered an integration of two technologies, geographic information system (GIS) and information assurance (IA), to stimulate students' interests in science, technology, engineering, and mathematics (STEM) career pathways and learning opportunities among high schools in underserved communities of the City of Detroit. Pre- and post-surveys demonstrated that the MYTC students showed growth in nearly every area covered in the surveys, including dispositions about STEM career and learning. A STEM career goal measure showed that overall interest in having a career in STEM increased 9 % throughout the program, with an additional 10 % for those who participated in an internship experience, the capstone of the MYTC project.

    In this paper we describe the DEMONSTRATOR structures and active units (PETALs) developed for the detector CALIFA of the experiment R3B - FAIR. The design is based in the CALIFA BARREL mechanical solutions, but adapted to the characteristics of the PETALs, namely in what concerns the load distribution during setup and service. The R&D program defined the materials and procedures for both producing the pieces of carbon fiber (CF) composites as well as the mounting of the bundles to make an alveolar structure. The procedures also include a quality control program to ensure the dimensional properties of the CF assemblies. We are also developing the use of tomographic imaging analysis for this quality program, that will be of mayor interest in the construction of the future CALIFA CF-structure.

    This document presents a first approach to study the behavior of a static fluid radiated by infrared light (980nm,100mW) transmitted by a single-mode optical fiber, for this simulation temperature and radiation pressure are calculated based on the intensity delivered by a laser diode. The Computing Fluid Dynamics (CFD) results were based on a mesh Tet/Hybrid, TGrid for a Silica micro-particle and a mesh Hex/Wedge, Cooper for the beam. The results show that as the particle moves along the axis, temperature and pressure decreases, having the points of mayor temperature and pressure around the axis. The conclusion of this work is that it is possible to simulate the interactions between the beam, the micro-particle and the surrounding medium in terms of temperature, velocity and pressure using the energy and viscous model.

    El R√≠o de la Plata (RdlP) presenta significativas variaciones naturales (hidrodin√°micas y oceanogr√°ficas) asociadas a diferentes condiciones clim√°ticas. El prop√≥sito de este trabajo es inferir los cambios de aportes continentales de sedimentos y su relaci√≥n con las variaciones hidrol√≥gicas del R√≠o de la Plata, a trav√©s del an√°lisis de proxies sedimentol√≥gicos y geoqu√≠micos en testigos de sedimentos de la plataforma interna uruguaya que registran los √ļltimos 100 a√Īos, aproximadamente. A partir de la dataci√≥n por 210Pb de dos testigos de sedimentos (GeoB 13813-4 y BAR1) se reconstruy√≥ la geocronolog√≠a del ambiente, y se relacion√≥ con datos de las forzantes clim√°ticas Pacific Decadal Oscillation, El Ni√Īo/La Ni√Īa Southern Oscillation, Atlantic Multidecadal Oscillation, y las anomal√≠as hidrol√≥gicas de los r√≠os Paran√° y Uruguay. Los valores m√°s positivos y estables del Southern Oscillation Index, los cuales corresponden a fases La Ni√Īa, se observan en el periodo correspondiente entre 1910-1970, respecto al resto de la serie, donde se aprecia una mayor variabilidad y una tendencia hacia valores m√°s negativos (eventos El Ni√Īo). Se hicieron dendrogramas (clustering) jer√°rquicos para ambos testigos. Para el testigo GeoB 13813-4, se utiliz√≥ la relaci√≥n Ca/Ti y la granulometr√≠a, mientras que para BAR1 se recurri√≥ a variables granulom√©tricas y la tasa de sedimentaci√≥n. El mayor aporte continental hacia la regi√≥n de la plataforma adyacente al R√≠o de la Plata registrado a partir del a√Īo 1970, podr√≠a ser el factor principal de los agrupamientos observados en los clusters para ambos testigos. Las agrupaciones mostraron una diferenciaci√≥n en la d√©cada de 1970, lo que estar√≠a asociado al aumento de los caudales de los r√≠os Paran√° y Uruguay, durante las √ļltimas tres d√©cadas del siglo XX. Por otra parte se observa que la granulometr√≠a del testigo BAR1 present√≥ un mayor tama√Īo de grano y m√°s variabilidad que en el caso del testigo GeoB 13813-4. Tambi√©n se determin√≥ una mayor acumulaci√≥n de sedimentos a trav√©s del tiempo en el cintur√≥n de barro del R√≠o de la Plata (plataforma continental adyacente), comparado con aquel registrado en la Barra del Indio (l√≠mite entre zona intermedia y externa del estuario). Estas diferencias podr√≠an estar relacionadas con la influencia del R√≠o de la Plata, el cual genera un ambiente altamente din√°mico sobre la Barra del Indio y un ambiente m√°s estable sobre el cintur√≥n de barro en la plataforma continental.

    The discovery of 51 Peg b by Mayor and Queloz revealed (among other things) that discovering extrasolar planets, though certainly difficult, was not as hard as professional astronomers had previously thought. At the same time, the astronomical equipment available to amateurs -- including optics, mountings, and CCD detectors -- had become quite capable. This combination of factors led to successful exoplanet programs that leaned heavily on amateur-grade hardware, seeking faster development times and lower costs than were possible for traditional no-compromises astronomical instrument programs. I will describe two of these in which I played a role: the AFOE (Advanced Fiber Optic Echelle) spectrograph, and the STellar Astrophysics and Research on Exoplanets (STARE) transit-search wide-field imager.

    SAR Interferometry (InSAR) has its unique advantages, e.g., all weather/time accessibility, cm-level accuracy and large spatial coverage, however, it can only obtain one dimensional measurement along line-of-sight (LOS) direction. Offset tracking is an important complement to measure large and rapid displacements in both azimuth and range directions. Here we perform offset tracking on detected point-like targets (PT) by calculating the cross-correlation with a sinc-like template. And a complete 3-D displacement field can be derived using PT offset tracking from a pair of ascending and descending data. The presented case study on 2010 M7.2 El Mayor-Cucapah earthquake helps us better understand the rupture details.

    How often will elections end in landslides? What is the probability for a head-to-head race? Analyzing ballot results from several large countries rather anomalous and yet unexplained distributions have been observed. We identify tactical voting as the driving ingredient for the anomalies and introduce a model to study its effect on plurality elections, characterized by the relative strength of the feedback from polls and the pairwise interaction between individuals in the society. With this model it becomes possible to explain the polarization of votes between two candidates, understand the small margin of victories frequently observed for different elections, and analyze the polls' impact in American, Canadian, and Brazilian ballots. Moreover, the model reproduces, quantitatively, the distribution of votes obtained in the Brazilian mayor elections with two, three, and four candidates. PMID:20856800
